Are you teaching Advanced Placement Computer Science? Are you looking for supplemental exercises that may help you students with the concepts? If so this announcement may be of interest to you. Pex for Fun has been around for a while offering coding duels in C#, F# and Visual Basic. Recently though it was decided to invest some time, money and effort to adapt some exercises specifically to help learn APCS concepts. Most students find the differences between Java and C# pretty minor at this level so most APCS students will find this doable even if they have only been taught Java previously.

Throughout the year I try to share resources and information with you that I think will be helpful for you. Often times these resources will include links to free eBooks that we make available on a variety of topics. Today, I thought I would post a large collection of eBooks for you here so that you can find them in one place and consume them as you see fit. Also, if you find this list helpful, please share it with your peers and colleagues so that they too can benefit from these resources.

"Late Friday, Wired writer Mat Honan ran into a digital buzzsaw as his iCloud, Gmail and Twitter accounts were compromised in rapid succession. The hackers did a tremendous amount of collateral damage along the way, spewing racist and homophobic tweets on Honan's account plus the Gizmodo Twitter account (linked to his). Worse, they proceeded to wipe all the data from his iPhone, iPad and his Mac laptop via Find My iPhone and Find My Mac."

Why it's a good idea to own a USB-to-SATA adapter The USB-to-IDE/SATA adapter the most indispensable tool in my PC repair kit. Just this weekend, it once again proved itself worthy of that title. In a nutshell, the adapter allows you to connect an internal hard drive to your PC-externally. What would an internal drive be doing outside your desktop or laptop? Funny you should ask. About a week ago, my media-center PC starting displaying this message during boot-up: "Hard drive failure imminent." And you know what? It was. In short order, the machine wouldn't boot at all. Long story short, I had to replace the drive, reinstall Windows, etc. But I wondered if I could salvage any/all of my recorded TV shows. To find out, I connected the old, non-booting drive (now "naked" outside the system) to a USB port via my adapter. Huzzah! The machine was able to read the drive and copy over the recordings. Except for the hassles (and expense) of actually replacing the drive, no harm done. There's another reason to keep one of these adapters on hand, and that's if you're planning to upgrade to a solid-state drive (SSD). Unless you buy a kit that comes with an adapter, you'll need one so you can image (i.e. clone) your existing drive to the new SSD. Then you'll remove the old drive, install the new one, and presto, you're back in business. (Much faster business: SSDs rock.) Unless you have a pretty old desktop or laptop, you can skip buying a USB-to-IDE/SATA adapter and just go for USB-to-SATA. At the same time, I recommend one that supports USB 3.0. You may not need it now, but it's a good bet your next PC will have USB 3.0 ports -- and that'll make for much faster copying between drives. Trust me: When the time comes that you need to upgrade or replace a hard drive, you'll be glad to have a USB-to-SATA adapter on hand. By-The Xpert Crew @ http://techvedic.com

"So I thought I would share a couple of habits that I find great when it comes to being a programmer and perhaps you will adopt a few yourself."

"From its humble beginnings in 2006, the Ubuntu Women mission has been clear - to encourage women to use and contribute to Ubuntu. The organization is not political, so you'll find no mentions of feminism or the like, but rather a safe place where women, curious about the Ubuntu developer community, can come and ask questions without fear of intimidation or condescension."

Microsoft has added a wonderful Windows repair tool to find a quick way out of Windows problems. This is actually a reverse gear, which you can use to alter any changes that might have incurred to the operating system due to faulty software or driver update, virus or malware attack, incompatible driver, or more. So don't forget to create Restore Point within a reasonable timeframe-say, the last couple of months to stay safe.

Despite updated operating system, browser, browser add-ons, installed firewall, and acute computer security settings, clever viruses, spyware or Trojans may find loop-holes to slip into your system. Not only in terms of performance, but in terms of stability and security too, these malicious software push you on back-foot. What to do next?

If you were not happy with the Surface RT touchscreen response, then it's worth to spend some time here. Tweaking the registry settings, you can find a quick and easy way around.

Most computer users have a haunting fear that somehow malware will find a way to sneak onto their PCs  when they are not looking. The truth is that while this does sometimes happen, the most common types of malware rely on trickery to invade and infect your computer.

Near-clone apps in the iOS App Store? It's not a new phenomenon, by any means; last week, developer Anton Sinelnikov had the bulk of his app library yanked from the store for plagiarism. In fact, high-profile app launches like RealMac Software's Clear can find themselves with unwanted "tribute" apps even before they arrive in the store.

"What these courses have in common, aside from the focus on Android development, is that they are all 100% free. You should be able to get yourself started off on developing your first app, and those who have some development experience will find advanced topics covered as well."

So, you want to learn the Python programming language but can't find a concise and yet full-featured tutorial. This tutorial will attempt to teach you Python in 10 minutes. It's probably not so much a tutorial as it is a cross between a tutorial and a cheatsheet, so it will just show you some basic concepts to start you off.

Deciding to become a software developer is a great initial step, congrats!  The job opportunities are growing quickly and in just about every industry that you can imagine.  The best part is that you do not necessarily have to go to a four year university to become a great software developer to lock down one of these jobs.  The web has all the resources you'll need to interact, learn, get support and finally find a job as a software developer.
