4 Things That Totally Suck About Using Technology In School [Opinion]


class="align-right" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/11/image19-300x300.png" alt="" />I’ve read that href="http://www.makeuseof.com/tag/the-best-6-sites-to-get-free-ebooks/">e-books are the future of books, and href="http://www.pcworld.com/article/243129/ebooks_vs_print_books.html">it’s not a matter of if they’ll surpass print books but when.  Being still in college, I wondered if that was the case for href="http://www.makeuseof.com/tag/3-websites-purchase-electronic-college-textbooks/">e-textbooks. There’s certainly more buzz on e-textbooks as they’re cheaper and it means that students don’t have to break their backs with heavy physical books. But are they better? Is going all digital better?

This whole semester I’ve been dealing with e-textbooks and using just an href="http://www.makeuseof.com/pages/best-android-apps">Android href="http://www.makeuseof.com/tag/5-fun-apps-kill-time-android-honeycombtablet/">tablet (Acer Iconia A500) to digitize all of my schoolwork to answer these questions. It’s not even the end of the semester but I can conclude that it’s been more of a hassle than a convenience. The href="http://www.makeuseof.com/tag/3-android-tablets-today-buyer-check/">tablet itself is great, but using technology in school isn’t quite the same. Remember the href="http://www.zdnet.com/blog/education/the-kno-is-deadlong-live-kno-thanks-to-30-million-from-intel-et-al/4545">Kno tablet? While I thought it was revolutionary, the concept didn’t seem to be picked up by schools. Universities, professors and students simply (some may be but most) aren’t ready to embrace digital textbooks, and not all professors make it easier for students who want to use their laptops or tablets to replace pen and paper.

Have An e-Textbook? You Will Fail An Open-Book Test

align="center"> class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/11/image20.png" alt="image" width="491" height="328" border="0" />

The argument of e-books versus traditional textbooks books goes beyond whether you prefer the look and feel of an actual book to the more unnatural book-on-a-screen experience. In terms of practicality, there are many obstacles and opposing forces to replacing physical books with digital versions for good. For instance, even right now when tablets have been hot for at least a year since the iPad 1 came out and there are quite a few people who can afford them, none of my professors at my href="http://www.makeuseof.com/tag/infographic-schools-rule-web/">apparently-expert-in-social-media school so far have declared that they prefer digital textbooks. One of my Computer Science professors reasoned that you can easily cheat on a test, go online on your web-enabled device and easily call or email your mom and ask her to look up the answer in a textbook for you. You could also simply Google the answer.

Having e-books and web-enabled devices also limit forms of testing, which is a just a headache for instructors. They’ll probably hate you for making them figure out a way you can’t cheat on the test and giving them additional work. This is true when the study material is as difficult as figuring out the answer to some obscure logic riddle, and some professors might prefer to give open-notes and open-textbook tests. Right now, since there are some students with the physical books and some with the e-books, those who purchase the digital versions of the textbooks end up disadvantaged.

align="center"> class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/11/image21.png" alt="image" width="364" height="439" border="0" />

Students could solve this by printing segments of their textbooks for the exams, but this is usually not permitted per the textbook publisher. How do I know this? My classmates who buy the (cheaper) digital textbook end up going through hoops of inconvenience to secure a remotely decent grade during these open-textbook exams. That usually includes having to figure out a way to bypass the limitation the textbook publisher has imposed for the e-book – you can only print 10 pages at a time. So the unpleasant options you have when you buy the digital textbook are to either print 10 pages at a time, harass a classmate to make photocopies of their physical book or buy the textbook anyway. I swear this is happening in one of my classes this semester.

Have An e-Textbook & Are Majoring In The Sciences? Your Book Will Confuse You

Another downside I have seen when traditional textbooks are replaced is that not all the text in a specialized textbook will be compatible with the rendering engine of an e-reader or tablet. I am NOT kidding. I’ve seen this first hand when one of my classmates who got the Kindle textbook ended up being totally confused with a formula. The way the formula was displayed on the Kindle involved a delta triangle instead of the correct symbols.

Talking about incompatibility, here’s an example of something equally confusing from my actual Logic class notes on my Android tablet.

align="center"> class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/11/image22.png" alt="image" width="580" height="497" border="0" />

I’m pretty sure those squares up there in the screenshot were meant to be curly braces, but that is just a guess.

Stylus Or Not, Hand-Writing On A Tablet Will Suck (& Be Slower Than If You Just Freakin’ Use Pen & Paper)

Right now, iPad and tablet owners have probably thought it best to try a stylus in the hope that they can replace paper. I know I have. I used href="http://www.amazon.com/Bamboo-Stylus-for-iPad-CS100K/dp/B004VM0SE6/ref=sr_1_1?ie=UTF8&qid=1320470440&sr=8-1">Bamboo’s Stylus for iPad, which is supposed to be one of the best styluses out there, on href="https://market.android.com/details?id=com.adsk.sketchbookhd">Autodesk’s SketchBook Pro, which is probably the best drawing app on the Android Market right now. Though both were good, no matter how long I tried to get used to it, I have found that using a stylus on a touchscreen just isn’t as pleasurable as it is using pen and paper.

It’s probably too much to ask for the stylus experience to be similar to what you get with a pen, I reckon, but it’s the precision and extra pressure you need to add that put me off. Want some proof? Here are my actual notes, taken with a stylus. Does this look legible to you?

align="center"> class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/11/image23.png" alt="image" width="580" height="384" border="0" />

Parts of my hand-writing aren’t so bad; some other parts look like hieroglyphs. If you own an iPad and have experienced something different, let me know in the comments. For me, no matter how much I try to like a stylus, it just doesn’t cut it for me.

align="center"> class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/11/image24.png" alt="image" width="568" height="416" border="0" />

As you can see here in my actual Logic class notes, another problem I’ve experienced is that if you’re focusing somewhat hard on making your notes legible, guess what, it’ll take you longer than usual and perhaps the professor will have moved on and erased the tidbit of information that was meant to copied quickly.

There are also problems when your tablet doesn’t actually support palm rejection or requires you to write really big and you have to keep zooming in and out. There have been some newer tablets that hold promise and seem to solve some of these problems, like the href="http://noteslate.com/">Noteslate (which seems to be vaporware), the HTC View and the href="http://www.youtube.com/watch?v=pz48l2Va3Wk">Lenovo Thinkpad tablet. If you have these tablets, please share your experiences in the comments.

Now if we’re talking about a graphics tablet (like a 12’’ href="http://www.wacom.com/en/Products/Cintiq/Cintiq12WX.aspx">Cintiq), it might be a whole different ball game, but you’ll have to lug around both your laptop and the graphics tablet to school, and set up your little office during every single class, provided you have enough desk space…

There’s No Way To Sync Last-Read Points In Your Study Material

align="center"> class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/11/image25.png" alt="image" width="357" height="290" border="0" />

You like having your leisure books synced on the Kindle, Kobo, Google Books, etc. apps, right? Imagine having to study books and slides (especially PDF slides and Powerpoint presentations that professors use so much these days) and not having a way to sync these across your computer, tablet or phone. It becomes increasingly annoying when there are more and more instructors relying on these slideshows and there’s always a need to either print them out (countering the purpose of saving paper in the first place) or re-figure out again where it is that you last read.

This frustration is something I’ve personally experienced and perhaps is not well-founded since you could try to figure out a way to remember the last checkpoints in your collection of slides, but I just don’t see why e-books can be synced so easily nowadays, yet digital slides, online tutorials, etc, aren’t so easy to organize.

align="center"> class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/11/image26.png" alt="image" width="580" height="324" border="0" />

That’s why I appreciate ideas like href="http://www.makeuseof.com/dir/ibisreader-cool-ebook-reader/">Ibis Reader which allows you to upload PDF documents and read them on the web with any device, but until the project is optimized for bookmarking last-read pages and so forth, it’s just for the casual reader that’s not in school.

Yes, Benefits Do Exist

I’ve encountered some inconveniences as you can see, but there are more good sides of owning a laptop , tablet or smartphone.

class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/11/image27.png" alt="image" width="580" height="347" border="0" />

Not only do tablets (and smartphones too!) make good clocks, they also are just lighter than a pile of textbooks of course, offer excellent battery life, are great e-readers (not for school), can be your personal planners, etc.

The point of this post isn’t to bash tablets or laptops. This rant is just my opinion of the current state of personal technology in schools. There are many ways to solve or remedy these concerns, but as of right now, the notion of having digital textbooks and using tablets for school is fraught with many problems. The transition to digitizing schoolwork is just fractured in many places because some are enthusiastic about the old ways, and others are ready to touch the future (on their tablets).

Decoding AMD’s Fusion Laptop Processor List [Technology Explained]


class="align-right" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/08/amdlaptop1.jpg" alt="" />In an earlier article I explained class="vt-p" href="http://www.makeuseof.com/tag/decoding-intels-laptop-processor-list-technology-explained/">the differences between Intel’s numerous laptop processors. But Intel is not the only company in this market. AMD remains, and its newly released Fusion product line is the most competitive mobile part the company has offered in years.

I’d like to be able to say that this new product line is easy to understand, but as is often the case with technology, it’s not. There are several different types of class="vt-p" href="http://www.makeuseof.com/tag/apu-technology-explained/">Fusion APUs available, and each has a difference balance of performance, price and efficiency.

Fusion In A Small Package – The C & E-Series

class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/08/Asus-Eee-PC-1215B.jpg" alt="" width="450" height="338" />

At the bottom of the entire AMD Fusion line you’ll find the C-Series, which consists of just two different APUs. In some odd positioning, the less expensive C-30 has a clock speed of 1.2 GHz while the more expensive C-50 ships at just 1 GHz. The catch? The C-50 has two cores.

The E-Series is more conventional. It again consists of just two parts, but the E-240’s clock speed of 1.5 GHz slots below the E-350’s speed of 1.6 GHz. Again, the part with the higher number offers two cores.

class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/08/amdlaptop2.jpg" alt="" width="386" height="329" />

If you’re looking for easy product differentiation baked into AMD’s naming scheme, you’re going to be disappointed. There isn’t any. Both the C and E-Series parts are built on the same micro-architecture and have the same integrated class="vt-p" href="http://www.makeuseof.com/tag/top-performing-laptop-video-cards-gaming-hd-video-technology-explained/">GPU. The only difference is clock speeds. In addition to the lower CPU clock on the C series, the graphics solution is limited to just a hair over 275 MHz, while the E series clocks as high as 500 MHz.

AMD must be hoping that, with only two processors in each series, consumers won’t have cause for confusion. While I think they’re correct, I hope they don’t intend to release many additional options for each line.

The Latest & Greatest – AMD’s Fusion A-Series

class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/08/amdlaptop3.jpg" alt="" width="500" height="316" />

While the original Fusion C and E Series parts have been around for months, they’re low-end processors, and not well suited for laptops selling over $500.  Those looking for a powerful processor are better off considering the new AMD Fusion A-Series.

There are more parts in the A-Series, but AMD has implemented a naming scheme that makes the list of processors somewhat easier to understand. The line is split into three different groups: A4, A6, and A8.

Among these, the A4 stands out the most. It is the only group that is made up of dual-core processors, and this also means that the class="vt-p" href="http://www.makeuseof.com/tag/cpu-technology-explained/">clock speeds are high despite the budget focus. Even the basic A4-3300M has a base clock of 1.9 GHz, which matches that of the quickest A8.  Graphics power comes courtesy of 240 Radeon cores clocked at 444 MHz.

Both the A6 and A8 parts are quad-core, and there isn’t a clear difference between them in clock speeds. Instead, the difference between these parts is the integrated graphics. The A8 offers 400 Radeon cores clocked at 444 MHz, while the A6 offers just 320 Radeon cores at 400 MHz.

class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/08/amdlaptop4.jpg" alt="" width="284" height="257" />

While this processor list isn’t as precise as Intel’s, the jist is clear. The higher the number behind the A, the better the graphics. Processor clock speeds and core counts, however, are not apparent in the processor’s name.

AMD for some reason decided to add the “MX” suffix to some of its A-Series processors. This is applied to the fastest A4, A6 and A8 options, but otherwise doesn’t indicate anything special about the processor.

Conclusion

While describing Intel’s processor list wasn’t easy, AMD has created a labyrinth of letters and numbers that don’t have little relation to the components they represent.

Fortunately, there are not as many parts to remember, so understanding AMD’s products isn’t as difficult as it could be. For now, at least. But if AMD continues to release parts into these same brands without clarifying the naming system used, consumers will not be at fault for their confusion.

What You Need To Know About Touchpads Before Buying Your Next Laptop [Technology Explained]


class="align-right" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/05/touchpadthumb.jpg" alt="" />If you walk into a retail store and ask a sales rep to explain a laptop to you, chances are you’ll receive a long list of hardware information focusing on what’s inside. You’ll be told what the processor is, you’ll be told the size of the hard drive, and you’ll be told the RAM installed.

This is information you’ll want to know, but in today’s world of speedy processors and cheap RAM, many users will rarely ask about all their laptop has to give. As a result, the difference between a good laptop and a great one comes down to the little things, like the touchpad. Yet the touchpad itself is a mysterious item. It’s there, it works, and it has for years. Not all touchpads are built the same however.

The Basics Of Touchpad Technology

class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/05/touchpad.jpg" alt="" width="500" height="375" />

The first class="vt-p" href="http://www.makeuseof.com/tag/how-to-disable-the-touchpad-while-you-are-typing/">touchpads made their debut in the early 1990s, and were one of several responses to the problem of providing an portable input solution with a portable computer (trackpointers and trackballs were also common). The first laptop to have a touchpad –or trackpad, as it was officially called at the time – was the Apple PowerBook 500.

Modern touchpads use a technology called capacitive touch. This is the same tech used by most modern class="vt-p" href="http://www.makeuseof.com/dir/touch-test-touch-screen-test-app/">touchscreens, and it works by detecting the electrical current of a human finger as it comes into contact with the touchpad surface. This allows for smooth, easy navigation that doesn’t rely on physical pressure.

However, capacitive touch does have one minor disadvantage, and that’s the inability to detect inanimate objects or gloved human hands. Special touchpads, like the tablets from class="vt-p" href="http://www.wacom.com/">Wacom, are required for use with a class="vt-p" href="http://www.makeuseof.com/answers/tag/stylus/">stylus. Fortunately, only artists and Eskimos routinely bump into this problem.

The Differences Between Touchpads

class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/05/touchpad4.jpg" alt="" width="412" height="530" />

While virtually all touchpads use the same basic technology to detect input, there are a wide variety of ways to use this technology, and a wide variety of touchpad sizes and textures.

The most important feature to look for in a touchpad is multitouch gesture support. Although this has become a common extra, it’s not ubiquitous. For example, I recently tested a MSI GT680R gaming laptop, priced at about $1,500, which did not have multitouch. Determining if a laptop supports this feature is easy if you can use it hands-on. Just try scrolling down a webpage with your middle and index fingers.

If a laptop doesn’t have multi-touch, it should at least have scroll space available. This is a small vertical area, usually on the right side of the touchpad, that’s exclusively designed to translate finger movement into an up/down scrolling motion.

Material quality, although low-tech, is critical. Most inexpensive laptops will simply construct the touchpad out of the same plastic as the surrounding laptop, and that works alright, but it doesn’t result in the smoothest feel. More expensive laptops, like the MacBooks, use a glass surface because it provides less resistance to finger movement. You’ll occasionally find other materials used, as well. The class="vt-p" href="http://event.asus.com/notebook/bamboo/index2.html">ASUS Bamboo series, for example, crafts the touchpad out of the same bamboo you’ll find on the rest of the laptop.

class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/05/touchpad6.jpg" alt="" width="550" height="411" />

Finally, the touchpad buttons are important. The best option is a touchpad that offers two separate physical mouse buttons, but many touchpads use what is called a rocker-style button. This means there is one individual with a rocker in the middle, which means the button operates like a seesaw. Rocker-style buttons look sexy, but they can be annoying to use because pressing the button near the rocker requires more force than pressing the button at the edge.

The perfect touchpad should offer multitouch support, a smooth surface, and two individual buttons with great tactile response. Finding all of these features together is difficult, particularly in inexpensive laptops, but it’s not impossible.

The Importance Of Software Support

class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/05/touchpad7.jpg" alt="" width="550" height="394" />

Although your touchpad’s hardware is important, the software being used also has an impact on how your touchpad performs.

For example, Windows did not even support multitouch until Windows 7 ( class="vt-p" href="http://www.makeuseof.com/tag/easily-activate-finger-scroll-windows-laptops/">although there are ways to hack it), even if the hardware was capable of it. Although much has been made about the inclusion of multitouch as it relates to tablets, its impact on laptops has been more immediate and obvious. Navigating Windows with a touchpad is much easier than before.

With that said however, there are still clear differences between Windows 7 and Mac OS X, which offers incredible multitouch support. Much of the difference between navigating Windows and Mac OS X on a laptop comes down not to the hardware (although the MacBook’s glass touchpad is nice) but to the software support. Ubuntu also offers full multitouch support as of version 10.10.

Conclusion

It’s easy to forget about the touchpad when a sales rep is gushing to you about the great hardware packed inside the new laptop you have your eye on. Don’t let that distract you. The touchpad is something you’ll be using a lot, and it cannot be replaced or upgraded, so you need to be sure to buy a laptop with a touchpad you like. />

    What A Hex Editor Is & Why You Might Use It [Technology Explained]


    class="align-right" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/03/xvi32.png" alt="what is a hex editor">The term hex, short for href="http://en.wikipedia.org/wiki/Hexadecimal">hexadecimal or base-16, is the raw data structure that all files stored on your computer follow. Although literally every file is stored on your computer in this format, you almost never see this data anywhere. Yet being able to directly modify the raw bits and bytes in your computer can sometimes be used to your advantage.

    So how does hex work, what is a hex editor and why might you need to use one on your PC?

    id="more-67096">

    What Is Hex?

    The number system that humans use to count is called decimal, the numbers from 0 to 9. Decimal was invented by the Persians about 6000 years ago.

    Fast forward to 1679. The binary number system made up of 0s and 1s was href="http://mathforum.org/library/drmath/view/52344.html">invented by Gottfried Wilhelm von Leibniz.

    Finally in the 1950s or 1960s IBM formalized the Hexadecimal number system, which is a short way to represent binary data. Instead of using digits 0-9, hexadecimal uses digits from 0 to F. Counting from 0 to 31 (converting from decimal to hexadecimal):

    0 1 2 3 4 5 6 7 8 9 A B C D E F 10 11 12 13 14 15 16 17 18 19 1A 1B 1C 1D 1E 1F

    Once you reach the end of the numeric “digits”, you simply increase the number to the left by one, just like you do with the decimal counting system.

    Now that we have the basics of hexadecimal out of the way, let’s move on to some hex editors.

    Hex Editors

    Hex editors differ from a regular text editors in a number of ways. The basis of a hex editor is that they display the raw contents of the file. No encoding or translation into text – just the raw machine code. The second is that line numbers instead of being based on “lines” are an offset address from the beginning of the file.

    href="http://www.pspad.com/en/">PSPad

    style="text-align: center;"> class="aligncenter" style="border: 0pt none;" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/03/pspad.png" alt="what is a hex editor" width="560" height="355" />

    My favorite hex editor is href="http://www.pspad.com/en/">PSPad. PSPad, in addition to being a great text and code editor, offers the “Open in HEX Editor …” option which will launch the special editing mode.

    Once you are in this mode, you can see the location and hexadecimal values of each bit of the file. You have two choices for editing the file – you can either edit the hexadecimal values by location, or on the right side you have the alphanumeric representation of that value which you can also edit.

    href="http://www.chmaas.handshake.de/delphi/freeware/xvi32/xvi32.htm">XVI32

    style="text-align: center;"> class="aligncenter" style="border: 0pt none;" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/03/xvi32.png" alt="what is a hex editor used for" width="560" height="356" />

    href="http://www.chmaas.handshake.de/delphi/freeware/xvi32/xvi32.htm">XVI32 is also a very capable hex editor. As with PSPad you can edit the hex values directly or the character representation.

    It also has some advanced hex editing tools such as an address calculator for checking offsets and some other hex-specific options which can help you get around a hex file if you know what you are doing.

    What Can You Do With A Hex Editor?

    Now that you know what a hex value is, and how you can open and edit them, why would you want to do that exactly?

    Find Out A File Type

    Every once in a while you might come across a file that you just can’t seem to open. It has a normal size, but Word or Adobe won’t open it. So can you do anything about that?

    The first thing I will do is open the file in a hex editor. Most files include some information in the very top of the file which describes what kind of file it actually might be.

    Below, is a character representation of an Adobe PDF file. Let’s say someone mistakenly saves a PDF file as a Microsoft Word .DOC file.

    style="text-align: center;"> class="aligncenter" style="border: 0pt none;" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/03/pdf-example.png" alt="what is a hex editor" width="158" height="302" />

    When your system sees that extension, it will try to launch Microsoft Word to open the file – but it will fail. Open the file in a hex editor, and it is immediately clear that this file is indeed a PDF file, and a quick switch to the file extension and you will be able to open it right up in Adobe Acrobat or other proper reader.

    If you see a filetype but have no idea what kind of program might be used to open that file, you might check out href="http://www.openwith.org/">OpenWith which lists many file extensions and the programs used to open them.

    Game & File Hacking

    Another popular reason you might use a hex editor is game hacking. You can load up a game href="http://www.fantasyanime.com/garden/savestatehacking2.htm">save state file and change the amount of money you have from $1,000 to $1,000,000, for example.

    Now, on more recent games this has been made much harder. Many modern games include either compression or encryption which make it many times more difficult to decompile the save state or game. However, some games still allow you to edit certain variables, such as in href="http://info.sonicretro.org/SCHG_How-to:Use_a_Hex_Editor">Sonic Spinball.

    In addition to looking into game files, sometimes you can glean other important information from a saved file that you otherwise might not have access to. This depends greatly on the type of file and what information you are looking for, but using a hex editor is useful in determining what exactly resides within a file.

    Debugging & Editing

    Finally the last main reason you might use a hex editor is if you are a programmer who is debugging your code. Instead of going back to recompile you code, a simple hex edit might be all you need to test out a verification pattern. Editing a raw binary file is not recommended for the feint of heart – modify just one character in a file could potentially render it useless. Make sure you have a backup before modifying any files using a hex editor.

    When a Hex Isn’t a Hex

    Hopefully you’ve learned a little bit about computers that you hadn’t known before, or at least have had your memory refreshed. Knowing how your computer ticks becomes more and more important as they become easier and easier to use. I know if you made it this far, you are ready to use these advanced strategies for getting the most out of the bits and bytes stored on your hard drive!

    What Is An APU? [Technology Explained]


    class="align-left" style="border: 0px none; margin-left: 20px; margin-top: 5px; float: right;" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/02/aputhumb.png" alt="what is an apu" width="207" height="194" />The CPU has been the heart of every PC since Intel’s x86 processors became popular over two decades ago. Yet the CPU does have weaknesses,the greatest of which is their relatively linear data execution. Graphics processors, by comparison, consist of many small cores that execute data simultaneously. This makes it easier for them to perform certain tasks, like video decoding and 3D graphics.

    Both Intel and AMD know this, and have for some time. In response they’ve combined the strengths of both CPUs and GPUs, resulting in a new type of product called the APU.

    id="more-65363">

    APU Architecture

    style="text-align: center;"> class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/02/apu1.jpg" alt="what is an apu" width="576" height="296" />

    What is an APU? The term APU stands for Accelerated Processing Unit. At the moment, this is a term that only AMD is using for its products. Intel’s recently released update to its processors also qualifies as an APU; Intel simply seems unwilling to use the definition. That’s understandable, since the company has been known as the world’s leading href="http://www.makeuseof.com/tags/cpu/">CPU maker for years.

    An APU is simply a processor that combines CPU and GPU elements into a single architecture. The first APU products being shipped by AMD and Intel do this without much fuss by adding graphics processing cores into the processor architecture and letting them share a cache with the CPU. While both AMD and Intel are using their own GPU architectures in their new processors, the basic concepts and reasons behind the decision to bring a GPU into the architecture remain the same.

    The Benefits Of An APU

    AMD and Intel wouldn’t go to the trouble of integrating a GPU into their CPU architectures if there weren’t some benefits to doing so, but sometimes the benefit of a new technology seems to be focused more on the company selling the product than the consumer. Fortunately, the benefits of the APU are dramatic and will be noticed by end users.

    style="text-align: center;"> class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/02/apu2.png" alt="what is an apu processor" width="500" height="400" />

    Obviously, improved performance is one advantage. The graphics placed on current APUs are not meant to be competitive with high-end or even mid-range discrete graphics cards, but they are better than previous integrated graphics processors. Intel HD Graphics 3000, the fastest graphics option available on the company’s newest processor, is href="http://www.anandtech.com/show/4083/the-sandy-bridge-review-intel-core-i7-2600k-i5-2500k-core-i3-2100-tested/11"> two to three times quicker than the previous Intel HD Graphics solution, which was on the processor die but not integrated into the architecture. This also makes it possible to include new features, like href="http://www.makeuseof.com/tag/intels-quick-sync-video-technology-explained/"> Intel’s QuickSync video transcoding techology.

    Another advantage brought by APUs is improved power efficiency. Integrated the GPU into the architecture makes it possible to share resources and achieve the same results with less silicon. This means an APU can replicate the performance of a system equipped with a low-end discrete graphics card while using far less power. Early benchmarks of Intel Sandy Bridge and AMD Fusion laptops make this advantage obvious; systems equipped with these processors have href="http://www.makeuseof.com/tag/20-ways-to-increase-the-life-of-your-laptops-battery/"> better battery life than similar system saddled with a CPU and a separate discrete or integrated graphics processor.

    Should You Buy One?

    style="text-align: center;"> class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/02/apu3.png" alt="what is an apu" width="450" height="225" />

    Now you know the benefits of an APU, you may be thinking about purchasing one of these fancy new processors. Upgrading to a new processor is never inexpensive, however. Is an APU worth your money?

    The answer is yes, but on the other hand, it doesn’t matter if you upgrade now or later. You are, eventually, going to end up owning an APU no matter what you do. All of Intel’s processors from here on, with the exception of the Atom processor, will be APUs. AMD’s entire line of processors will be updated to APUs by the end of this year. And Nvidia, which recently announced intentions to create a line of ARM processors for desktops, will of course be creating an APU.

    In fact, you may want to wait, if only because this technology is relatively new. Both Intel and AMD are hard at work on new products that further leverage the advantages of this design, and AMD’s desktop APU is unlikely to become available before the summer.

    Conclusion

    The APU is the future of processor design. The only question at this point is the term itself. While Intel’s new processors also fit the definition of an APU, the term APU is only used by AMD in its marketing. If Nvidia also decides this is a term worth using as it develops its new processor it may have some legs. Otherwise, I wouldn’t be surprised if Intel uses its considerable marketshare might to squash it.

    But whatever this new generation of hardware is called five years from now, the results are the same. APUs are here, they’re awesome, and they’ll make it easier for users to enjoy media without consuming unreasonable amounts of power.

    The benchmark graph is part of Anandtech’s href="http://www.anandtech.com/show/4083/the-sandy-bridge-review-intel-core-i7-2600k-i5-2500k-core-i3-2100-tested"> review of Intel’s Sandy Bridge processors. Check it out for full information. />

    What All This MD5 Hash Stuff Actually Means [Technology Explained]


    class="align-left" style="border: 0px none; margin-left: 20px; margin-top: 5px; float: right;" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/02/intro.jpg" alt="md5 hash" width="180" height="180" />In a recent article about checking whether you were href="http://www.makeuseof.com/tag/find-email-address-leaked-gawkers-database/">affected by Gawker’s hacking incident, one of the steps involved converting your email address into an MD5 hash.

    We had a few questions from readers asking exactly what was going on, and why this process was necessary. It’s not our style to leave you guys asking questions, so here’s a full run-down of MD5, hashing and a small overview of computers and cryptography.

    id="more-64811">

    Cryptographic Hashing

    MD5 stands for Message Digest algorithm 5, and was invented by celebrated US cryptographer Professor Ronald Rivest in 1991 to replace the old MD4 standard. MD5 is simply the name for a type of cryptographic hashing function Ron came up with, way back in ’91.

    The idea behind cryptographic hashing is to take an arbitrary block of data and return a fixed-size “hash” value. It can be any data, of any size but the hash value will always be fixed. Try it for yourself href="http://www.miraclesalad.com/webtools/md5.php">here.

    style="text-align: center;"> class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/02/cryptohash.png" alt="md5 hash" width="539" height="385" />

    Cryptographic hashing has a number of uses, and there are a vast number of algorithms (other than MD5) designed to do a similar job. One of the main uses for cryptographic hashing is for verifying the contents of a message or file after transfer.

    If you’ve ever downloaded a particularly large file ( href="http://www.makeuseof.com/pages/getting-started-guide-linux">Linux distributions, that sort of thing) you’ll probably have noticed the hash value that accompanies it. Once this file has been downloaded, you can use the hash to verify that the file you downloaded is in no way different to the file advertised.

    The same method works for messages, with the hash verifying that the message received matches the message sent. On a very basic level, if you and a friend have a large file each and wish to verify they’re exactly the same without the hefty transfer, the hash code will do it for you.

    Hashing algorithms also play a part in data or file identification. A good example for this is peer to peer href="http://www.makeuseof.com/dir/tag/file-sharing/">file sharing networks, such as eDonkey2000. The system used a variant of the MD4 algorithm (below) which also combined file’s size into a hash to quickly point to files on the network.

    style="text-align: center;"> class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/02/md4hash.png" alt="what is md5 hash" width="300" height="330" />

    A signature example of this is in the ability to quickly find data in hash tables, a method commonly used by search engines.

    style="text-align: left;">Another use for hashes is in the storage of passwords. href="http://www.makeuseof.com/dir/password-tool-storing-passwords-online/">Storing passwords as clear text is a bad idea, for obvious reasons so instead they are converted to hash values. When a user inputs a password it is converted to a hash value, and checked against the known stored hash. As hashing is a one-way process, provided the algorithm is sound then there is theoretically little chance of the original password being deciphered from the hash.

    Cryptographic hashing is also often used in the generation of passwords, and derivative passwords from a single phrase.

    Message Digest algorithm 5

    The MD5 function provides a 32 digit hexadecimal number. If we were to turn ‘makeuseof.com’ into into an MD5 hash value then it would look like: 64399513b7d734ca90181b27a62134dc. It was built upon a method called the Merkle–Damgård structure (below), which is used to build what are known as “collision-proof” hash functions.

    style="text-align: center;"> class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/02/merkledamgard.jpg" alt="what is md5 hash" width="581" height="271" />

    No security is everything-proof, however and in 1996 potential flaws were found within the MD5 hashing algorithm. At the time these were not seen as fatal, and MD5 continued to be used. In 2004 a far more serious problem was discovered after a group of researchers described how to make two separate files share the same MD5 hash value. This was the first instance of a collision attack being used against the MD5 hashing algorithm. A collision attack attempts to find two arbritary outputs which produce the same hash value – hence, a collision (two files existing with the same value).

    Over the next few years attempts to find further security problems within MD5 took place, and in 2008 another research group managed to use the collision attack method to fake href="http://www.makeuseof.com/tags/ssl/">SSL certificate validity. This could dupe users into thinking they are browsing securely, when they are not. The US Department of Homeland Security href="http://www.kb.cert.org/vuls/id/836068">announced that: “users should avoid using the MD5 algorithm in any capacity. As previous research has demonstrated, it should be considered cryptographically broken and unsuitable for further use“.

    style="text-align: center;"> class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2011/02/Selection_159.png" alt="md5 hash" width="580" height="291" />

    Despite the government warning, many services still use MD5 and as such are technically at risk. It is however possible to “salt” passwords, to prevent potential attackers using dictionary attacks (testing known words) against the system. If a hacker has a list of random often-used passwords and your user account database, they can check the hashes in the database against those on the list. Salt is a random string, which is linked to existing password hashes and then hashed again. The salt value and resulting hash is then stored in the database.

    If a hacker wanted to find out your users’ passwords then he would need to decipher the salt hashes first, and this renders a dictionary attack pretty useless. Salt does not affect the password itself, so you must always href="http://www.makeuseof.com/dir/randomkeygen-generate-multiple-secure-passwords-quickly/">choose a hard-to-guess password.

    Conclusion

    MD5 is one of many different methods of identifying, securing and verifying data. Cryptographic hashing is a vital chapter in the history of security, and keeping things hidden. As with many things designed with security in mind, someone’s gone and broken it.

    You probably won’t have to worry too much about hashing and MD5 checksums in your daily surfing habits, but at least now you know what they do and how they do it.

    The Difference Between DDR2 & DDR3 RAM [Technology Explained]


    class="align-left" style="border: 0px none; margin-left: 20px; margin-top: 5px; float: right;" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2010/09/ddrramthumbnail.jpg" alt="ddr memory" width="300" height="198" />RAM, or Random Access Memory, is your computer’s short term memory. If your computer needs information and does not find the RAM, it then needs to journey to the class="vt-p" href="http://www.makeuseof.com/tag/all-the-tools-you-need-to-predict-the-death-of-your-hard-drive/">hard drive to try and retrieve the data, which is far more time consuming. Many older computers that feel sluggish can be given new life if upgraded with additional RAM.

    However, capacity is only one specification. RAM is also available in a variety of versions and speeds. A 2GB stick of DDR2 800 RAM is not the same thing as a 2GB stick of DDR3 1333 RAM. Understanding the difference is important because computers will generally accept only certain types of RAM.

    id="more-52913"> /> Let’s take a look at the different types of DDR memory on the market and how they are different from each other.

    The Big Issue: DDR2 vs DDR3

    In late 2008, Intel released the first Core i7 processors. These processors were paired with a new motherboard chipset called X58. This chipset introduced the need for a new type of memory called DDR3.

    style="text-align: center;"> class="aligncenter" style="border: 0pt none;" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2010/09/ddrram1.jpg" alt="ddr memory"/>

    In the last two years the entire industry has converted over to DDR3. All of Intel’s new processors can only be used with a motherboard that requires DDR3. Recent AMD motherboards are also changing over to DDR3.

    The term “DDR” stands for Double Data Rate RAM. This term came into use at the turn of the century when the first Double Data Rate RAM modules arrived. Double Data Rate RAM was capable of two data transfers per clock cycle, giving it twice the theoretical peak bandwidth of previous SDRAM while running at the same clock speed.

    style="text-align: center;"> class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2010/09/ddrram2.jpg" alt="ddr ram" width="350" height="220" />

    DDR2 and DDR3 are improvements on the same technology and further increase the number of data transfers per clock cycle. DDR2 RAM provides 4 data transfers per cycle, while DDR3 increases the number to 8. Assuming a base clock speed of 100Mhz, DDR RAM will provide 1600 MB/s of Bandwidth, DDR2 provides 3200 MB/s, and DDR3 provides 6400 MB/s. More is always better!

    Performance & Compatibility Consequences

    Does this mean you’ll notice a big difference between DDR2 and DDR3 systems? Well, maybe not. While the increase in memory bandwidth is great, the truth is that 99% of programs are not capable of creating a workload that will be restricted by memory bandwidth. The issue is most relevant to server and workstation class products.

    To see a difference in performance you’ll usually need to use a class="vt-p" href="http://www.makeuseof.com/tag/5-free-benchmark-programs/">benchmark program capable of testing memory bandwidth.

    style="text-align: center;"> class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2010/09/ddr3ram.jpg" alt="ddr ram" width="480" height="209" />

    However, purchasing DDR2 or DDR3 RAM isn’t usually a matter of preference. DDR2 and DDR3 RAM are not compatible. If your motherboard uses DDR2, you cannot upgrade to DDR3 without upgrading your motherboard. This means that if you currently own a computer with DDR2 RAM and you want to upgrade to a brand new processor and motherboard you have to throw your your perfectly good DDR2 RAM and buy new DDR3 RAM.

    There are a few motherboards which are exceptions to this rule, but they are exceptions only because they provide both DDR2 and DDR3 RAM slots, and these exceptions are available only on older chipsets.

    I know – it’s a bummer, but there isn’t much you can do about it. Both Intel and AMD have committed to DDR3 RAM for future products, so you’ll be forced to either buy new RAM and deal with your computer becoming a dinosaur.

    Clock Speed – The Other Part Of The Equation

    style="text-align: center;"> class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2010/09/ddrram4.jpg" alt="ddr memory" width="399" height="284" />

    Another important specification to consider when looking at RAM is the clock speed. Clock speed is an indication of how well the RAM will perform in much the same way that clock speed indicates how well a processor will perform, and it is part of the equation that determines the maximum theoretical peak bandwidth of memory. A higher clock speed is better. However, as I mentioned previously, this is a difference that is unlikely to be noticeable in normal daily use. The typical enthusiast won’t see much benefit from memory with a higher clock speed.

    With that said, there are motherboards that only accept memory within a limited range of clock speeds. It is always a good idea to consult a motherboard manufacturer’s website to double-check the RAM that is compatible. Motherboards are usually very flexible in this regard, but it is better to be safe than sorry.

    Conclusion

    The bad news is that the invention of DDR3 is making DDR2 obsolete by force. I have four sticks of spare DDR2 memory that are no longer capable of finding a home in a new system, even a low-power class="vt-p" href="http://www.makeuseof.com/tag/using-your-linux-computer-as-a-media-center-part-1/">HTPC or office computer, because of the change. The good news is that new RAM technology is at least several years off, so DDR3 purchased today should be good for a while. Just be sure to check the type of RAM a new motherboard requires before purchasing RAM to go with it!

    Basic Types and Requirements for Web Designing: Given by Pseudo Technology


    Web site design crosses multiple disciplines of information systems, information technology and communication design. The web site is an information system whose components are sometimes classified as front-end and back-end. The observable content (e.g. page layout, user interface, graphics, text and audio) is known as the front-end. The back-end comprises the organization and efficiency of the source code, invisible scripted functions, and the server-side components that process the output from the front-end. Depending on the size of a Web development project, it may be carried out by a multi-skilled individual (sometimes called a web master), or a project manager may oversee collaborative design between group members with specialized skills.

    Multidisciplinary requirements:

    Issues: As in collaborative designs, there are conflicts between differing goals and methods of web site designs. These are a few of the ongoing ones.

    1. Lack of collaboration in designIn the early stages of the web, there wasn’t as much collaboration between web designing and larger advertising campaigns, customer transactions, social networking, intranets and extranets as there is now. Web pages were mainly static online brochures disconnected from the larger projects. Many web pages are still disconnected from larger projects. Special design considerations are necessary for use within these larger projects. These design considerations are often overlooked, especially in cases where there is a lack of leadership, lack of understanding of why and technical knowledge of how to integrate, or lack of concern for the larger project in order to facilitate collaboration. This often results in unhealthy competition or compromise between departments, and less than optimal use of web pages.

    2. Liquid versus fixed layoutsOn the web the designer has no control over several factors, including the size of the browser window, the web browser used, the input devices used (mouse, touch screen, voice command, text, cell phone number pad, etc.) and the size and characteristics of available fonts. Some designers choose to control the appearance of the elements on the screen by using specific width designations. This control may be achieved through the use of a HTML table-based design or a more semantic div-based design through the use of CSS. Whenever the text, images, and layout of a design do not change as the browser changes, this is referred to as a fixed width design. Proponents of fixed width design prefer precise control over the layout of a site and the precision placement of objects on the page. Other designers choose a liquid design. A liquid design is one where the web designing moves to flow content into the whole screen, or a portion of the screen, no matter what the size of the browser window. Proponents of liquid design prefe greater compatibility and using the screen space available. Liquid design can be achieved through the use of CSS, by avoiding styling the page altogether, or by using HTML tables (or more semantic divs) set to a percentage of the page. Both liquid and fixed design developers must make decisions about how the design should degrade on higher and lower screen resolutions. Sometimes the pragmatic choice is made to flow the web designing between a minimum and a maximum width. This allows the designer to avoid coding for the browser choices making up The Long Tail, while still using all available screen space. Depending on the purpose of the content, a web designer may decide to use either fixed or liquid layouts on a case-by-case basis. Similar to liquid layout is the optional fit to window feature with Adobe Flash content. This is a fixed layout that optimally scales the content of the page without changing the arrangement or text wrapping when the browser is resized.

    3. Flash.Adobe Flash (formerly Macromedia Flash) is a proprietary, robust graphics animation or application development program used to create and deliver dynamic content, media (such as sound and video), and interactive applications over the web via the browser. Adobe Flash is today widely used in Web Designing. Flash is not a standard produced by a vendor-neutral standards organization like most of the core protocols and formats on the Internet. Flash is much more restrictive than the open HTML format, though, requiring a proprietary plug-in to be seen, and it does not integrate with most web browser UI features like the “Back” button.According to a study, [1] 98% of US Web users have the Flash Player installed. [2] Numbers vary depending on the detection scheme and research demographics. [3] Many graphic artists use Flash because it gives them exact control over every part of the design, and anything can be animated and generally “jazzed up”. Some application designers enjoy Flash because it lets them create applications that do not have to be refreshed or go to a new web page every time an action occurs.

    What Is An API & What Are They Good For? [Technology Explained]


    class="align-left" style="border: 0px none; margin-left: 20px; margin-top: 5px; float: right;" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2010/08/communication.jpg" alt="what does api stand for" />What does the acronym API stand for? API means Application Programming Interface and they say that APIs are the underlying aspect of Web 2.0.  But what does it really mean – what is an api? Let’s try to demystify the term a little.

    The word to really pay attention to is “Interface”. If you have any experience at all with programming, all kinds of abstractions and contracts must be coming to your mind when you hear the word “interface” but we are more interested in the classical meaning of the term.

    An interface is a common boundary between two separate systems. It is the means or the medium via which these two systems communicate.

    id="more-51415">

    Definition

    An API is the interface implemented by an application which allows other applications to communicate with it.

    Why Is It Needed?

    In one word – communication. You might ask why communication is so important. Just imagine Notepad couldn’t copy-paste to and from Microsoft Word or class="vt-p" href="http://www.makeuseof.com/dir/tag/chrome/">Google Chrome. Imagine having to type each and every time although the text is already there in some other application. This is only one of the examples of communication between applications and all this communication is made possible via APIs.

    What Is It Really?

    You cannot run an API like you would run say a class="vt-p" href="http://www.makeuseof.com/tags/notepad/">Notepad application. This is because APIs are generally invisible to the end users like you and me. APIs are carefully thought out pieces of code created by programmers for their applications that allow other applications to interact with their application.

    APIs are specially crafted to expose only chosen functionality and/or data while safeguarding other parts of the application which provides the interface. Creating an API is indeed time well spent, because ultimately the more applications that interact with your application the more popular it becomes.

    style="text-align: center;"> class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2010/08/twitterclients.jpg" alt="what does api stand for" />

    An excellent example is class="vt-p" href="http://www.makeuseof.com/dir/tag/twitter/">Twitter. Most people prefer their favorite class="vt-p" href="http://www.makeuseof.com/tag/twitter-clients-web-apps-desktops-apps/">Twitter client instead of the web interface. You can interact with Twitter whether you are using a mobile phone, a smart phone, an iPod or a computer. This has been made possible by the excellent class="vt-p" href="http://apiwiki.twitter.com/">Twitter API.

    What Is It Good For?

    As we have seen, APIs facilitate communication allowing different applications to communicate effectively with each other. So these are really well suited for extending a platform and for class="vt-p" href="http://www.makeuseof.com/dir/tag/mashup/">mashups. We have already seen Twitter as an example of how APIs are useful in extending a platform. When you combine data or functionality from more than one application to create another application, you have essentially created a mashup.

    Such mashups are extremely popular on the Internet these days. The Internet thrives on communication so it is an ideal place to take advantage of APIs. It is a common practice to expose part of your functionality or data as an API to others on the Web. They can then tap into what you offer, combine it with what they (or someone else) offers and then provide improved and added functionality to their users.

    style="text-align: center;"> class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2010/08/googlemapsyelp.png" alt="what does api stand for" width="519" height="370" />

    class="vt-p" href="http://www.makeuseof.com/tag/search-fo-worst-local-businesses-yelp">Yelp for example has data on restaurants, hotels, shopping destinations and other local services but it would be a wasteful and tedious job if they set out to create their own Maps engine to let users know where the various destinations are. So instead they tap into the Google Maps API and plot their data on top of it, thereby increasing the utility of their service to the end user. This is a typical use of an API.

    Popular APIs You Can Use Or Try

    APIs are all over the place. The most popular ones are the Web APIs like class="vt-p" href="http://code.google.com/apis/maps/index.html">Google Maps API, class="vt-p" href="http://apiwiki.twitter.com/">Twitter API and the  class="vt-p" href="http://www.flickr.com/services/api/">Flickr API. These are not the only ones though. You can find a complete, classified and searchable directory of APIs at class="vt-p" href="http://www.programmableweb.com">Programmable Web and class="vt-p" href="http://www.webmashup.com/">WebMashup. Here you can see the level of interest in an API, what services are provided by the API and which services are making use of the API.

    How you actually use an API depends upon your needs and your level of expertise. You might want to create the next big thing on the Internet, in which case you would most likely need to program for the Web using languages such as PHP, ASP.NET, Java or Python. A good starting point is to visit the official API page for the service you choose. Look for libraries others have written in the language of your choice. Usually these libraries make your job a lot easier and faster. Twitter for example mentions a number of these class="vt-p" href="http://dev.twitter.com/pages/libraries">libraries on its API wiki. You can also find tutorials, official documentation and best practices on these pages.

    APIs have existed in one form or another for a very long time. The first communication between cooperating applications may or may not have been through an officially documented API, but nowadays they are an important component of your application especially if yours is a Web application.

    Have you ever created or used an API? We would love to hear about your experiences in the comments.

    Basic Layout and Requirements for Web Designing: by Pseudo Technology


    CSS versus tables for layout:

    When Netscape Navigator 4 dominated the browser market, the popular solution available for designers to lay out a Web page was by using tables. Often even simple web designing for a page would require dozens of tables nested in each other. Many web templates in Dreamweaver and other WYSIWYG editors still use this technique today. Navigator 4 didn’t support CSS to a useful degree, so it simply wasn’t used. After the browser wars subsided, and the dominant browsers such as Internet Explorer became more W3C compliant, designers started turning toward CSS as an alternate means of laying out their pages. CSS proponents say that tables should be used only for tabular data, not for layout. Using CSS instead of tables also returns HTML to a semantic markup, which helps bots and search engines understand what’s going on in a web page. All modern Web browsers support CSS with different degrees of limitations. However, one of the main points against CSS is that by relying on it exclusively, control is essentially relinquished as each browser has its own quirks which result in a slightly different page display. This is especially a problem as not every browser supports the same subset of CSS rules. For designers who are used to table-based layouts, developing Web sites in CSS often becomes a matter of trying to replicate what can be done with tables, leading some to find CSS design rather cumbersome due to lack of familiarity. For example, at one time it was rather difficult to produce certain design elements, such as vertical positioning, and full-length footers in a web designing using absolute positions. With the abundance of CSS resources available online today, though, web designing with reasonable adherence to ,;;’ standards involves little more than applying CSS 2.1 or CSS 3 to properly structured markup. These days most modern browsers have solved most of these quirks in CSS rendering and this has made many different CSS layouts possible. However, some people continue to use old browsers, and designers need to keep this in mind, and allow for graceful degrading of pages in older browsers. Most notable among these old browsers are Internet Explorer 5 and 5.5, which, according to some web designers, are becoming the new Netscape Navigator 4 – a block that holds the World Wide Web back from converting to CSS design. However, the W3 Consortium has made CSS in combination with XHTML the standard for web designing.

    Form versus Function:

    Some web developers have a graphic arts background and may pay more attention to how a page looks than considering other issues such as how visitors are going to find the page via a search engine. Some might rely more on advertising than search engines to attract visitors to the site. On the other side of the issue, search engine optimization consultants (SEOs) are concerned with how well a web site works technically and textually: how much traffic it generates via search engines, and how many sales it makes, assuming looks don’t contribute to the sales. As a result, the designers and SEOs often end up in disputes where the designer wants more ‘pretty’ graphics, and the SEO wants lots of ‘ugly’ keyword-rich text, bullet lists, and text links. One could argue that this is a false dichotomy due to the possibility that a web designing may integrate the two disciplines for a collaborative and synergistic solution. Because some graphics serve communication purposes in addition to aesthetics, how well a site works may depend on the graphic designer’s visual communication ideas as well as the SEO considerations. Another problem when using a lot of graphics on a page is that download times can be greatly lengthened, often irritating the user. This has become less of a problem as the internet has evolved with high-speed internet and the use of vector graphics. This is an engineering challenge to increase bandwidth in addition to an artistic challenge to minimize graphics and graphic file sizes. This is an on-going challenge as increased bandwidth invites increased amounts of content.

    Accessible Web design:

    Main article:

    Web accessibilityTo be accessible, web pages and sites must conform to certain accessibility principles. These can be grouped into the following main areas:use semantic markup that provides a meaningful structure to the document (i.e. web page)Semantic markup also refers to semantically organizing the web page structure and publishing web services description accordingly so that they can be recognized by other web services on different web pages. Standards for semantic web are set by IEEE-use a valid markup language that conforms to a published DTD or Schema-provide text equivalents for any non-text components (e.g. images, multimedia)-use hyperlinks that make sense when read out of context. (e.g. avoid “Click Here.”)-don’t use frames-use CSS rather than HTML Tables for layout.-author the page so that when the source code is read line-by-line by user agents (such as a screen readers) it remains intelligible. (Using tables for web designing will often result in information that is not.)However, W3C permits an exception where tables for layout either make sense when linearized or an alternate version (perhaps linearized) is made available.Website accessibility is also changing as it is impacted by Content Management Systems that allow changes to be made to webpages without the need of obtaining programming language knowledge.

    What Google Chrome Canary Is [Technology Explained]


    class="align-left" style="border: 0px none; margin-left: 20px; margin-top: 5px; float: right;" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2010/08/0-canary-intro.jpg" alt="google chrome canary" width="270" height="223" /> class="vt-p" href="http://www.google.com/chrome/intl/en/landing_chrome.html?hl=en&platform=win">Google Chrome is now my default browser for pretty much everything. The stable release has finally got to a point where it is stable enough for me to use all the time. I’ve even been using the class="vt-p" href="http://www.google.com/chrome/eula.html?extra=betachannel">beta/ class="vt-p" href="http://www.google.com/chrome/eula.html?extra=devchannel">developer builds of Chrome on my laptop without any problems.

    On July 22, Google, being all about speed, announced that they were going to shorten the release cycles of new, stable versions of Chrome from quarterly to 6 weeks. With this announcement came the Canary release channel.

    In this article, I am going to explain exactly what class="vt-p" href="http://tools.google.com/dlpage/chromesxs">Google Chrome Canary is and why you should be excited about its release. I will explain the meaning of its name, as well as its overall purpose in the grand scheme of things.

    id="more-51208">

    Why Call It Canary?

    By calling the release Canary, Google is referring to the old technique of using canaries in coal mines. Back in the day, coal miners used to bring canaries down in the mines with them as a precaution. If there was any kind of deadly gas build-up, the canary would be the first to die. If the canary died, everyone knew it would be a good idea to leave the mine as soon as possible.

    style="text-align: center;"> class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2010/08/1-canary-version.png" alt="google chrome canary" width="522" height="294" />

    Chrome Canary offers the same set of precautions. The Canary build is less stable, but it will be used to test even more cutting-edge features than the developer’s build, which already tests new features before they are pushed to the beta build. If a change “kills” Chrome Canary, Google will block it from the developer build.

    What’s Different About It?

    Chrome Canary is somewhat of a mix between the Chrome developer build and the Chromium snapshot builds. It can be run side-by-side with any other channel, which is a new feature. This means that it isn’t linked to your other Chrome installs and can therefore run different class="vt-p" href="http://www.makeuseof.com/tag/cool-tips-you-can-use-to-get-more-out-of-bookmarks-in-chrome/">sync profiles, class="vt-p" href="http://www.makeuseof.com/tag/design-browser-theme-google-chrome/">themes, class="vt-p" href="http://www.makeuseof.com/dir/tag/chrome/">apps, and use different preferences.

    Unlike the other channels (beta and dev), Canary’s side-by-side feature allows builds to be installed without overwriting a regular Chrome build, which means that, technically, you can install both a Canary build and a regular build that could be on the stable, beta or dev channel.

    style="text-align: center;"> class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2010/08/2-canary-icons.png" alt="google chrome canary" width="270" height="285" />

    If you install Chrome Canary, you will notice that it has a different, all-yellow icon instead of the multi-colored Chrome icon or even the all-blue icon you might be accustomed to. Also, the skin of the browser is blue, helping you tell it apart from other versions of Chrome as well.

    style="text-align: center;"> class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2010/08/3-canary-default.png" alt="google canary" width="538" height="208" />

    [Note]: As Canary is a secondary installation of Chrome, you cannot set it as the default browser. Also, it is currently only available on Windows.

    Why Is It Necessary?

    Giving users the option to run a more advanced version of Chrome without having to fully commit to alpha testing it should help increase the number of people willing to use the browser.

    style="text-align: center;"> class="aligncenter" src="http://main.makeuseoflimited.netdna-cdn.com/wp-content/uploads/2010/08/4-canary-dev.png" alt="google canary" width="580" height="214" />

    Canary will auto-update more frequently than any other versions available to developers. Google is working on making it update as often as they have successful nightly builds, according to their class="vt-p" href="http://groups.google.com/a/chromium.org/group/chromium-dev/browse_thread/thread/bf71d02dae94eb88?pli=1">developer’s email list. When something doesn’t work on the Canary, you can just fall back on your beta version.

    Also, by speeding up the Chrome development cycle, it will begin testing new features with the public and collecting feedback more quickly. The data – especially crash statistics – that they get back from users will help them find (and fix) regressions in the software faster.

    [Note]: Since the Canary version of Chrome will be very unstable, it should only be used by those who are willing to risk losing browsing data in the event of a program crash.

    Conclusion

    Well there you have it. As I stated earlier, I use Google Chrome as my browser, so I am quite pleased with the news of a faster development cycle. Google seems to be very enthusiastic about getting their browser to the top and class="vt-p" href="http://www.makeuseof.com/tag/2-reasons-google-chrome-pull-mozilla-firefox/">surpassing Mozilla once and for all.

    From a user’s standpoint, I think this is good news for all of us. Quicker releases mean better features, and better features for Chrome should inspire some of these other companies to pick up the pace with their browsers as well.

    What do you think of this news? Will you be giving Canary a try?

    The Mp3 Bible – Technology and Religion


    One of the most technologically advanced versions of the Bible is an MP3 Bible. For those of you who do not know what an MP3 is, it stands for MPEG Audio Layer 3. It is a digital audio technology that allows you to compress music or sound files into much smaller files with little or no loss of sound quality. It is able to do this by removing inaudible information from the file. You can store MP3s on your computer and upload and download them over the Internet, which means they can be listened to on a variety of different media, including CD players, iPods and MP3 players, or right on the default media player of your personal computer.

    The entire narrated Audio Bible which takes 72 hours to listen to, has been recorded onto traditional audio CD’s and requires about 60 audio CDs to hold all the recordings. In contrast, to give you an idea of how much compression takes place using the MP3 format, you only need to use two to four MP3 CD-ROMs to hold the entire MP3 Bible, which can then be uploaded or downloaded to your playing device. This technology has changed the way the Bible can be delvered to audiences. By making it extremely easy to transport and use the Bible MP3 recordings at conferences, retreats, catechism classes where children’s Bible stories are played, evangelism and outreach programs, and listening groups there is now a wider range of sharing the message of the Bible . Many different Christian websites even offer free audio Bible downloads and daily Bible Podcasts that you can sign up for online. Well-known pastors sometimes record the Podcasts themselves and they often contain short dramatizations of the Bible or homilies related to the weekly readings.

    Since many cultures in developing parts of the world have never heard the Word of the God or ever had a chance to hold a copy of Bible in their hands, MP3 Bibles are one of the best new ways to share the scriptures with them. Many volunteer organizations will bring MP3 Bibles and other audio Bible formats to villages and play them for a large group. When used in conjunction with printed Bibles, children and villagers who have not learned to read can follow along and begin learning written words. Right now there are audio Bibles for hundreds of different languages, and new translations are being worked on as we speak.

    Whether you prefer reading the Bible, listening to Bible MP3 recordings at home or at the gym, you have many new opportunities to incorporate the Bible into your life and the lives of others around you. You can even donate MP3 Bibles to those less fortunate to help evangelize the Good Word and spread the teachings of Jesus to other cultures in countries far from your own.

    The Rio Mp3 Player – Affordable Mp3 Technology


    For music enthusiasts everywhere, the most modern version of portable music enjoyment is the MP3 player. A small and comprehensive system that holds your personal play lists, keeps track of your calendar, and even allows video function has revolutionized the way in which we are entertained. The MP3 player was designed for a modern society on the go; such technology allows us to enjoy music no matter where we are or what we are doing. The most popular system on the market today is the Apple iPod. The iPod’s infinite success has prompted a variety of companies to get into the game of MP3 technology – including Sonic Blue’s Rio MP3 player.

    The MP3 player technology works to compress audio files to such a size that they can be contained in a much smaller physical space than traditional vinyl records or CDs. Users are able to download their favorite music – sometimes up to thousands of songs depending on the unit – and construct their own personal play lists that remain on their portable MP3 player. The Rio MP3 player is no different in this technology.

    The Rio MP3 player is available in a number of different models offered at different price points. They include the Rio Karma, Rio Cali, Rio Chiba, CE2100, Forge Sport, Rio One, Carbon, Fuse Street, and the Nitrus – the first MP3 player to include a one-inch hard drive.

    The Rio MP3 player has been marketed to people who have different needs from their MP3 player. Whether you listen to your MP3 player in your car, while working out, or at home, there is a Rio MP3 player that is right for you.

    Consumers have responded to the Rio MP3 player for its affordable technology. While it does not provide all of the features popular to iPod or Microsoft Zune, it is an affordable option for those interested in having a MP3
