As someone who uses Windows Vista practically daily, I've always wondered where all the negativity in the media comes from. Sure, Vista isn't perfect (as if any operating system is), but I just don't see where all the complaints are coming from. It runs just fine on my old (6 years) machine, all my software and hardware is compatible, and it's stable as a rock. Microsoft has been wondering the same thing, and after a little test, they may have found out why people seem to dislike Vista so much.

What is so hard about UAC running an md5 against the exe file in question.
IT'S NOT POSSIBLE!
First example:
1. user executes destroy.exe: UAC prompt, user clicks on "always consent"
2. malware executes destroy.exe, no prompt because the exe is the same.
-> you're pwned!

Incorrect. End user loads it once, knows that it is an application he or she wants to use on a constant basis - heck, it could be their very own application they've written.
If you do an md5, compare the result of the stored one to the one done at the execution of the application - if malware has through some way replaced the legitimate file with something bad - the md5 comparison will fail and a warning along the lines of "exe has failed security check, file possibly compromised, excution haulted".
Second example:
1. user changes a firewall rule: UAC prompt, user clicks on "always consent"
2. malware changes a firewall rule, no prompt because the firewall configurator executable is the same.
-> you're pwned!
Third example:
1. user copies a file in c:\windows using windows explorer: UAC prompt, user clicks on "always consent"
2. malware copy a trojan in c:\windows, no prompt because the copy command executable or the explorer.exe is the same.
-> you're pwned!

If you are going to compare, don't be dishonest and quote only the first half; the issue was addressing a specific question; the specific question was a specific executable file. It didnot involve file copying, it didn't involve anything else. It involved running one piece of software and the contious asking whether its ok to run it because it isn't signed.
The issue has NOTHING to do with UAC, because it isn't UAC querying the end user. This security check exists on Windows XP to; if you choose to run something downloaded via the internet from the download window - when one clicks on 'open', one is faced with the same question.

"At the end of a week in which Electronic Arts confirmed it wasn't developing a thing for the Wii U, one of the software engineers in EA Sports' Canada studio, in a series of since-deleted tweets, disparaged the console as 'crap' and suggested Nintendo should give up on hardware altogether. 'The Wii U is crap. Less powerful than an Xbox 360. Poor online/store. Weird tablet', tweeted Bob Summerwill, listed as a senior software engineer at EA Canada, in a reply to a tweet posting a link about EA's no-Wii U news. 'Nintendo are walking dead at this point'." The Wii U is turning into the 21st century's Virtual Boy.

"In NixOS, the entire operating system - the kernel, applications, system packages, configuration files, and so on - is built by the Nix package manager from a description in a purely functional build language. The fact that it's purely functional essentially means that building a new configuration cannot overwrite previous configurations. Most of the other features follow from this." Interesting approach. A Linux distribution, sure, but with some very refreshing ideas about system configuration.

Appfour added, among other features, C/C++ support to its new version of AIDE. From Android-IDE, "Now you can write parts of your app or your whole app in C/C++ on your device. AIDE supports the Standard Android NDK toolchain (GCC 4.6 + Bionic, STL, ...). No changes are necessary if you want to build an app developed on a PC with Eclipse. C/C++ development is fully integrated: Build errors appear in the error list and files can easily be navigated to with Go to file. The editor supports C/C++ syntax highlighting."

Ars nails it: "The answer is that Google did announce what amounts to a fairly substantial Android update yesterday. They simply did it without adding to the update fragmentation problems that continue to plague the platform. By focusing on these changes and not the apparently-waiting-in-the-wings update to the core software, Google is showing us one of the ways in which it's trying to fix the update problem."

"It is good for programmers to understand what goes on inside a processor. The CPU is at the heart of our career. What goes on inside the CPU? How long does it take for one instruction to run? What does it mean when a new CPU has a 12-stage pipeline, or 18-stage pipeline, or even a 'deep' 31-stage pipeline? Programs generally treat the CPU as a black box. Instructions go into the box in order, instructions come out of the box in order, and some processing magic happens inside. As a programmer, it is useful to learn what happens inside the box. This is especially true if you will be working on tasks like program optimization. If you don't know what is going on inside the CPU, how can you optimize for it? This article is about what goes on inside the x86 processor's deep pipeline."

"It was the only moment I heard regret slip into Otellini's voice during the several hours of conversations I had with him. 'The lesson I took away from that was, while we like to speak with data around here, so many times in my career I've ended up making decisions with my gut, and I should have followed my gut,' he said. 'My gut told me to say yes.'" The world would've been a much different place - Apple would have been less dependant on Samsung for its chips, which probably would've meant less money for Samsung to develop its Galaxy business.

Glass is getting some love at Google I/O as well. New applications have been released - Facebook, Twitter, Evernote, Elle, Tumblr, and CNN. Perhaps more interesting: the newly announced Google Glass Developer Kit will allow offline applications and direct hardware access - great for hacking and expanding Glass' potential. This kit will really allow hackers to put Glass through its paces.

"But Beck and Merrill decided that simply banning toxic players wasn't an acceptable solution for their game. Riot Games began experimenting with more constructive modes of player management through a formal player behavior initiative that actually conducts controlled experiments on its player base to see what helps reduce bad behavior. The results of that initiative have been shared at a lecture at the Massachusetts Institute of Technology and on panels at the Penny Arcade Expo East and the Game Developers Conference." Absolutely fascinating stuff. I'm a League of Legends player, and to be honest, the community isn't nearly as bad as some make it out to be. I'm happy Riot games has the guts to employ science to address the issue.

"Android and iOS, the number one and number two ranked smartphone operating systems worldwide, combined for 92.3% of all smartphone shipments during the first quarter of 2013 as Windows Phone crept past BlackBerry for 3rd place. According to the International Data Corporation Worldwide Quarterly Mobile Phone Tracker, Android smartphone vendors and Apple shipped a total of 199.5 million units worldwide during 1Q13, up 59.1% from the 125.4 million units shipped during 1Q12." Windows Phone doubles from a few to twice few, iOS loser market share as its growth is slower than that of the overall market. BlackBerry continues slide into irrelevance.
