Computing in the Core is a non-partisan advocacy coalition of associations, corporations, scientific societies, and other non-profits seeking to elevate the national profile of computer science education in K-12 within the US and work toward ensuring that computer science is one of the core academic subjects in K-12 education.

Non-Myths About Programming

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

I frequently see a problem when people (especially techies) try to teach programming to someone (especially non-techies). Many programming tutorials begin with basic programming principles: variables, loops, data types. This is both an obvious way to teach programming and almost certainly a wrong way to teach programming. It's wrong because nobody wants to learn how to program

Good find, Doug. His book is excellent: http://inventwithpython.com/chapters/

Welcome to the distribution center for BYOB (Build Your Own Blocks), an advanced offshoot of Scratch, a visual programming language primarily for kids from the Lifelong Kindergarten Group at the MIT Media Lab. This version, developed by Jens Mönig with design input and documentation from Brian Harvey, is an attempt to extend the brilliant accessibility of Scratch to somewhat older users-in particular, non-CS-major computer science students-without becoming inaccessible to its original audience. BYOB 3 adds first class lists, sprites, and procedures to BYOB's original contribution of custom blocks and recursion.

Last year we introduced HTTPS by default for Gmail and encrypted search. We're pleased to see that other major communications sites are following suit and deploying HTTPS in one form or another. We are now pushing forward by enabling forward secrecy by default. Most major sites supporting HTTPS operate in a non-forward secret fashion, which runs the risk of retrospective decryption. In other words, an encrypted, unreadable email could be recorded while being delivered to your computer today. In ten years time, when computers are much faster, an adversary could break the server private key and retrospectively decrypt today's email traffic.

Aeronautics to Writing MIT offers a wide selection of online (non-credit) video based courses. The computer science one is particularily good.

"Topics include abstraction, algorithms, encapsulation, data structures, databases, memory management, security, software development, virtualization, and websites. Languages include C, PHP, and JavaScript plus SQL, CSS, and HTML. Problem sets inspired by real-world domains of biology, cryptography, finance, forensics, and gaming. Designed for concentrators and non-concentrators alike, with or without prior programming experience."

Everyone is familiar about the term SIM (Subscriber Identification Module) which means small card slides into the back of many smartphones available in the market. Basically, it acts as an official identifier which depicts that your mobile phone belongs to you.
