OpenCL University Kit from AMD for computer science students

February 28th, 2011

AMD has announced the introduction of the OpenCL University Kit, a set of materials that can be leveraged by any university to assist them in teaching a semester course in OpenCL programming.

OpenCL is the non-proprietary industry standard available today for heterogeneous computing to help developers to harness the full compute power of both the CPU and GPU to create innovative applications for vivid computing experiences.

“As a former professor at Washington University in St. Louis, I firmly believe that the university setting is a vital environment to cultivate the best and brightest minds and set them on a path to succeed,” said Manju Hegde, corporate vice president, AMD Fusion Experience Program. “By ensuring that an industry standard like OpenCL is a central element of the education process, we are helping to put the PC application ecosystem in good hands to take full advantage of a heterogeneous computing future.”

“Teaching students to effectively leverage the OpenCL standard involves all the intricacies of parallel programming plus support for a new class of heterogeneous computing devices built on a variety of hardware technologies,” said David Kaeli, professor and associate dean of undergraduate programs, Northeastern University College of Engineering. “The OpenCL University Kit introduced by AMD is an easy tool to enable educators to quickly introduce OpenCL learning into their curriculum, helping them strike a balance between teaching syntax and higher level architectural issues.”

Included in the University Kit is a 13 lecture series, equipped with instructor and speaker notes, as well as code examples where necessary. An advanced understanding of OpenCL is not needed to understand the course materials; students only require a basic knowledge of C/C++ programming. A C/C++ compiler and an OpenCL implementation (such as the AMD APP SDK) are needed to complete the exercises.

For students and developers who are interested in presenting technical papers on heterogeneous computing, AMD will be holding its first AMD Fusion Developer Summit from June 13-16 in Seattle, Washington. Proposals can be submitted until February 25. Summit participants will engage in interactive sessions and hands-on labs to deepen their knowledge of advanced CPU and GPU programmability, and gain a better understanding of how software applications can take full advantage of the parallel processing power of APUs, bringing supercomputer-like performance to everyday computing tasks.

Idaho’s education reforms attract computer makers

February 28th, 2011

As Idaho looks at education reforms that could place laptops in every high school, computer companies are already eyeing what could become a lucrative contract with the state.

Public schools chief Tom Luna unveiled his sweeping overhaul at the start of the 2011 Idaho Legislature, calling for the state to place laptops and other technology in the hands of high school students while making online courses a requirement to graduate.

The legislation call for the state Department of Education to provide a classroom’s worth of mobile computing devices, which could be laptops to start and later come in the form of other electronics such an iPad or another tablet, in every high school for the next five years.

While online education providers stand to profit in Idaho should lawmakers decide to make their courses mandatory, computer makers could also make a bundle if the reforms are placed into law. And a handful of companies have already contacted the state.

“We’ve been very careful with the vendors that have approached and certainly what we’ve said to them is that, there’s going to be a task force that comes forward with recommendations,” aid Luna’s chief of staff, Luci Willits. “We have not engaged any vendors.”

A budget plan for the proposed reforms includes $4.7 million each year, for five years, to phase in laptops for high school students. There’s another $2.3 million to $9.5 million budgeted each year for maintenance, repairs and support. Altogether, a statewide contract could be worth an estimated $57.2 million over five years.

The legislation calls for Luna to form a task force that would decide how to implement the online course requirements and the laptop program, making recommendations on the types of devices Idaho should use and whether there should be a statewide contract or multiple contracts for individual school districts.

Idaho may not be picking sides yet when it comes to which company would provide the hardware, but at the state Legislature, it’s not uncommon to find a lobbyist for Apple Inc. touting the latest technology being used in the classroom or to hear a representative from chip-maker Intel Corp., praise Luna’s education reforms at a public hearing.

“Most of the people who have been there from these companies are their education arms, so they’ve brought research and have been able to show how technology can influence the classroom,” Willits said. “Certainly there’s another arm, which is the vendor arm, and we’ve not engaged any vendors whatsoever.”

House Education Committee Chairman Bob Nonini was among lawmakers impressed last week during a presentation by Apple Inc., which provides laptops to Maine students under a four-year, $64 million lease signed in 2009 and showed off some of the latest mobile devices and online curriculums being used by students.

“I think technology is great. I wish we would have had it in our era but we didn’t,” Nonini said. “I don’t think we can let the kids move forward without it.”

Democrats on the committee were more skeptical and questioned how much the technology would cost and whether teachers had been let go to help pay for computers in other states. Under the Idaho plan, the state would increase class sizes in grades four through 12 to pay for a bulk of the education reforms, cutting 770 teaching jobs.

State Rep. Brian Cronin, a Boise Democrat, sits on the education committee and said he felt like he was being “sold a solution” for public schools.

“Apple is, after all, a high-tech manufacturing company,” Cronin said. “And as unusual as it might be for Apple to come to us and say: ‘What do you guys think will be the next great iPhone?’ … I’m not sure I understand the idea of a high-tech company necessarily advising us on educational policy.”

Apple lobbyist Renee Sinclair countered she was merely trying to brief lawmakers, at their request, on the latest online applications being used in schools.

“We show them on Apple products because that’s what we do. We’re not here to sell you a product,” said Sinclair, who later hailed the company’s experience with big state initiatives like the one proposed in Idaho. “We’ve tried to be a resource here as this legislation is moving through,” she said.

When asked if Apple would ultimately like to be the company that provides the hardware should Idaho adopt the reforms, Sinclair said: “I would imagine we would … My role is to talk about policy. There are sales people, when that time comes, who will deal with that end of it.”

The legislation to boost technology in the classroom remains in the Idaho Senate, where it was introduced this month and is being reworked amid lawmaker concerns that include increased class sizes. The Senate passed two other bills that are in Luna’s reform package and would eliminate tenure for new teachers, restrict collective bargaining and introduce merit pay

This session not the first time companies have been sure to get their name in while the state considers legislation that would place more education-driven products in the classroom.

“The same thing happened when the textbook program, this happened with (Idaho Standardized Achieve Test) remediation,” said Department of Education spokeswoman Melissa McGrath. “Anytime there’s an additional revenue stream for school districts, those companies call us and will look at that revenue stream and see how they can participate.”

The Decline (and Fall?) of Computer Books

February 24th, 2011

If you’re a publisher or author of a computer book — you have my sympathy. Times are tough. And they’re only likely to get tougher going forward.

The larger arc of the story is a familiar one. Computer-related books are located inside the same Internet blast radius that has so far devastated the music industry, print journalism, DVD sales, and book retailers (witness Borders bankruptcy filing last week).

Still, the details regarding computer books are worth a closer look.

The industry survives. But it’s struggling against forces largely beyond its control. The assault on the computer book industry comes from three directions:

1. Vanishing target audience

Before the rise of the Internet, if you wanted to learn more about your computer (let’s say a Mac), you had three main choices: Join a user group, subscribe to a magazine or buy a book. For a time, all three alternatives thrived. By comparison, all three are suffering today. The book market has been especially hurt by an erosion of its target audience.

Computers (we’ll focus on Macs here for obvious reasons) have become easier to use than ever. As for iPhones and iPads, most of what you need to know can literally be mastered by a three-year-old. If you do need more hand-holding, Apple’s retail stores offer a wealth of introductory help. The result is that many beginning users, who might have purchased a Mac books years ago, find it unnecessary today. More and more, today’s audience would not purchase an introductory-level computer book for the same reasons they don’t expect to have to purchase a 300+ page volume on HD televisions.

What about the other end of the spectrum? The advanced user. I’m not talking about developers and network administrators here. I’m talking about one step down — the people we used to refer to as “power users” — the guys who leads SIGs at Mac Users Groups, rather than attending them. Surely they retain the motivation to sit down with a good in-depth Mac book. Right? Nope. Not so much. For them, the knowledge base gets updated far too rapidly to depend on the relatively glacial pace of change in book publishing.

In between, there remain a cadre of “intermediate level” users that might still benefit from a book and be sufficiently motivated to buy one. But, as in politics, I believe these centrists are diminishing as the market bifurcates to the two extremes.

The end result? Bad news for Mac (and iOS device) books.

2. The pace of change

I’ve already hinted at this problem. As I see it, you cannot write — and revise — a Mac or iOS book sufficiently fast enough or often enough to keep pace with the rate of change.

Some of you may be aware that (a long, long time ago in a galaxy far, far away), I wrote a book titled Sad Macs, Bombs, and Other Disasters. The first edition was over 600 pages, which was a “big book” at the time, although not record-breaking in size. What you probably don’t know is that the interval from the day I signed my book contract to the day the book appeared on store shelves was….almost 18 months. My writing pace, together with the wealth and depth of material I was covering, turned out to require it. Yes, this was considered a long interval even back in those days. But my point is that such an interval was at least possible. It was tolerated — because a book with this long a delay could still be a success. Sad Macs progressed through four editions. By its third edition, Sad Macs had become a number #1 best-seller.

Such tolerance is a thing of the past. In the current environment, Sad Macs would be doomed to fail.

For one thing, major changes to hardware and software occur much more rapidly now. The span of one recent 18 month period, for example, covered the end of the life-cycle for the iPhone 3G, the entire life cycle of the iPhone 3GS, and the release of the iPhone 4. At the same time, the iOS went from iOS 2.x to 4.x. An iPhone book would ideally need to be written, and updated at least twice, during this interval in order to stay current.

Actually, it’s worse than that. Users begin anticipating a new model or OS version for months before its release, as news about the product begins to emerge. For example, Mac OS X Lion has already been announced, even though it probably won’t see the light of day until September. A new iOS version comes out about every year. The next version is typically announced several months before it goes on sale, so as to allow developers to revise their apps in time for the release. The result is that a book about iOS is considered obsolete within 9 months of the iOS version’s release. After this, people start holding off on a purchase, waiting for the next edition of the book. This means that, if a new iOS book doesn’t come out until 4 months after the iOS is first available, the shelf life of the book is only about 4-5 months!

Here’s where the other shoe drops. One way to lengthen the shelf life of a computer book is to get it out sooner. In other words, rather than taking four months after a new iOS version is released to publish a book about the iOS, have the book come out within four weeks. This has an added benefit: It’s a well-known axiom that the first book(s) out of the gate sell the most copies, even if they later turn out to be far from the best books on the subject.

As a result, the pressure to get a book out “fast” is more intense than ever. The dilemma is: How can you possibly begin and complete a book within a few weeks of a product’s release? The answer is: You can’t. What authors do is write the majority of the book before the product goes on sale. They accomplish this sleight-of-hand via rumors, beta versions of software, existing similar hardware, and educated guesses. When the product is at last released, the book draft is quickly revised to (hopefully) resolve any errors due to discrepancies between the theoretical and actual product. And then it’s off to the publisher.

In my opinion, such books can never be of the highest quality. Numerous errors inevitably slip through. Plus, important details that can only be learned from actually working with the product for a period of time are completely ignored. For more advanced topics, such as my own troubleshooting forté, it would be impossible to do a decent book in this manner. This is another reason why such books have largely vanished from the marketplace.

3. The Internet

Given the rapid rate of change just described, it’s almost impossible for print computer books to keep up. Potential readers know this. That’s why they are turning instead to online resources.

While it may take a bit more effort to ferret out information via a Google search than grabbing a book off your shelf, the Web information is usually free and almost certainly more current than a book. For example, when iOS 4.2.1 was released, details about its new features were online within 24 hours. Solid, in-depth material was posted within a week.

Reading a half-dozen scattered websites loses the unified vision and voice of a good book. But this is not enough to allow books to compete effectively with the Web.

The future

What can book authors and publishers do to meet these challenges? I believe the future of the computer book industry, if it has one at all, depends on ebooks. These digital books don’t entirely level the playing field with the web, but they may make it close enough. Most especially, without the delays and costs required for print, a publisher can bring an ebook to market significantly faster and cheaper than a print book. Updating an ebook, especially if the changes are relatively minor, is much much quicker to do than with a print book.

With ebooks, there is the potential for another advantage not possible with print books. If the publisher can maintain some sort of “registration” of purchases (as software publishers do), they can offer minor updates to a book for free and major upgrades at a substantial discount compared to a new purchase. Again, as with software, this can encourage purchasers to become “subscribers” to a book, making it much more likely that existing owners continue to buy new editions. In the end, I believe this can generate greater and more steady revenue than the traditional print models.

For the author, this model will likely mean a smaller (or no) advance. But it may offer a greater royalty percentage. Plus, an author doesn’t have to worry about getting charged for unsold copies of their book. In the end, for a successful book, the author can make out quite well. This is already the model used by Tonya and Adam Engst’s Take Control books.

I don’t expect print computer books to disappear altogether. However, I predict that, within the next couple of years, the vast majority of Mac and iOS-device book sales will be ebooks. Most such books will be available only as an ebook. The “golden age” of print computer books is behind us. Computer books, print or ebook, will never again be the dominant force they once were. For better or worse, they are another casualty of our digital age.

Hacked and Hijacked: What to Do if Your PC Gets Compromised

February 24th, 2011

There are a range of telltale signs that your PC has been infiltrated by a binary ne’er-do-well, but, counterintuitively, the worst case scenario is when there are no obvious symptoms at all. For starters, you may have an infection if your PC or Internet throughput has become consistently sluggish, and a restart doesn’t cure it. Frequent, random pop-up windows with ads or system warnings are almost always clues to an infection. And, if you’ve discovered that your login credentials for any website have been hijacked — whether for e-mail, banking or Facebook — there’s a possibility that malware is on your PC.

Diagnosis:
You’re doubtless familiar with at least a few of the ever-multiplying terms for the nasties that can frustrate and even destroy your PC, such as viruses, Trojans, worms, malware, adware, spyware and rootkits. Depending on what bug your computer has caught, the ailment may just be an annoying hindrance, like those viruses that reset your browser home page or spew Viagra pop-up ads. Some varieties, however, are legitimately dangerous. Some can suck up all of the personal info from your PC and send it off to a remote hacker. Others can record your keystrokes in order to steal the password to any site. Still others can take complete control of your PC — using it to send out spam e-mails by the millions, to host porn or illegal software, or even to attack corporations and governments. Botnets — networks of thousands or even millions of hacked PCs that have been turned into “zombie” armies under the control of an individual or group — are actively used by organized crime these days. It’s serious stuff.

Side note: At the risk of starting a commenter flame war, currently all of these ills — and by that we mean 99.999999-percent, in real-world circumstances — only affect Windows users. So, if you are a Mac or Linux user who hasn’t shut off your firewall or installed sketchy pirated software, any computer issues you have are almost definitely software- or hardware-related. We’re sure some day soon you’ll have to worry about this stuff, and a few instances of malware on OSX have crept up, but it’s currently a non-issue. You’d certainly be smart to run anti-virus software, but the odds your OS X or Linux box have been infected with something are extremely low to non-existent. (Flame on!)

If you’re a Windows user and have ruled out software and hardware issues, it’s safe to assume you’ve been infected with something. Congratulations! Figuring out what it is, or they are, can be as simple as running a garden variety anti-virus program. For especially devious bugs, though, you may need more specialized care. In some cases, it may end up being more time- and cost-efficient to call it a day, erase your hard drive altogether, and reinstall the OS — after backing up all of your important files and media to an external hard drive first!

Causes:
Hopping online without having a secure, “hardened” PC is the equivalent of walking down a dark alley with wads of Benjies hanging out of your pockets. An old but intriguing study by the SANS institute documented how a bare Windows XP system would be compromised in under 20 minutes simply by being plugged into the ‘Net. The good news is that Microsoft has made great strides with security since then, and Windows 7 in particular is notably robust out-of-the-box (and technically even more secure than Apple’s vaunted OSX, by some accounts). Yet, for some reason, a healthy plurality of Windows users still use XP (about 40-percent). Plus, while there have been a million security patches in the intervening years, a lot of users just don’t bother to install updates, much less upgrade their operating system.

As a result, even basic Web surfing on an older, unmaintained PC is enough to get socked by so-called drive-by infections (whereby simply visiting sites that have been hijacked can install malware on your PC). Downloading torrents and cracked software are also surefire ways to put your PC at risk. Simply visiting torrent sites (and porn sites) can be just as disastrous. Flash drives are especially popular in corporate and government espionage, and an exceedingly common way for malware to be spread. But, by far the most prevalent way to hose your PC is by clicking on links in places you shouldn’t: spam e-mails, pop-up windows, and unsolicited messages on Skype and instant messaging applications.

With older Windows systems, users often sign into their PCs as administrators. If a user does so, and he is duped into accidentally installing malware, the bug is able to burrow deep into the PC. Newer versions of Windows require users to enter the administrator password every time they want to install something that can affect the system (instead of just their account).

Treatment:

1. As always, back up all your most important files, applications and data to an external hard drive, lest you lose it all if your PC dies on you. You should do this regularly anyway, but definitely do it now.
2. Check and make sure a firewall is installed and running. (Click here to see how depending on your Windows Version.)
3. Install all the Windows security patches you may have neglected in the past; if you’re a novice user with generally basic needs, we’d recommend allowing automatic updates directly from Microsoft, though advanced users may prefer to do so manually. (Click here for info on how to enable automatic updates.)
4. Update and run an anti-virus program. (Remember the one you quit updating when the free trial ran out?) Either pay up, or install a free version of anti-virus/malware software, such as Microsoft’s own Security Essentials 1.0 or Ad-aware Free Internet Security (which we prefer). Update them, run them, and run them again. It may take a while depending on how big your hard drive is and how slowly your PC runs.
5. If things still aren’t hunky-dory, you’ll need to try a hybrid approach. Install and run an alternate security application, such as Spybot Seach and Destroy (free) or pony up for Spyware Doctor 2011 ($30), Norton Anti-Virus 2011 ($40) or Kaspersky Anti-Virus 2011 ($40); we’re partial to Spyware Doc as it gets top marks from testing labs, but it’s still possible for any one of these programs to clean up stuff others can’t, and vice versa. Be warned that you’ll likely have to uninstall or disable security software before installing and running new ones or they’ll cause trouble; check the specifications of whatever program you use first before attempting to install another.
6. Some malware is smart enough to prevent you from doing any of the above, or will have hacked up your system so thoroughly that you’ll need to download anti-virus software to a separate PC, put it on a flash drive and then plug it into the infected PC and attempt to install and run it. If that doesn’t work, trying rebooting your PC into safe mode (by hitting F8 until you see the Safe Mode screen after hitting restart). And if that fails you may need to boot from a system CD that came with your PC, and then install and run the downloaded software.
7. It’s still possible that newer rootkits and malware can evade detection or removal from even top-shelf security programs, in which case you’ll need pro help. We’re fans of the Tech Support Guy forums, where kind-hearted experts diagnose and try to cure intractably sick machines for free. But the process isn’t for the faint-hearted, and is best left to the technically inclined. It’s worth a shot, though; otherwise it’s up to you to find a reliable and trustworthy professional — and again, make sure you’ve backed up everything before handing your PC over to anyone.
8. If you haven’t already, create an administrator account on your PC. Then, create another account for you (or several for family members) that requires you to log out and use the administrative password whenever you want to install software. (Click here for directions.) These maneuvers will go a long way in keeping malware and crapware off your PC.
