+ - Ask Slashdot: What's there to like about the BETA?-> 7

Submitted by Narnie
Narnie (1349029) writes "I come to /. not for the nearly interesting pseudo-tech articles, but for the lively, self-moderated discussion. Today I'm bit surprised to see every discussion summarized to fuckbeta. Popping up all over the place there's discussions about beta and even alternatives being revived and created. As I tend not to RTFA, I haven't sampled the beta myself. So, I ask you guys, what's there to like about the BETA and what's there to loath?"

+ - Demonstrating a Weakly-Ordered CPU->

Submitted by Narnie
Narnie (1349029) writes "Jeff Preshing provides a C++11 demonstration of using shared memory on a weakly-ordered CPU and the resulting memory reordering when not properly using memory_order_acquire and memory_order_release constraints. Preshing writes in his blog:

If there’s one thing that characterizes a weakly-ordered CPU, it’s that one CPU core can read values from shared memory in a different order than another core wrote them. That’s what I’d like to demonstrate in this post using pure C++11. For normal applications, the x86/64 processor families from Intel and AMD do not have this characteristic. So we can forget about demonstrating this phenomenon on pretty much every modern desktop or notebook computer in the world. What we really need is a weakly-ordered multicore device. Fortunately, I happen to have one right here in my pocket: The iPhone 4S fits the bill. It runs on a dual-core ARM-based processor, and the ARM architecture is, in fact, weakly-ordered.

As commenter Ross Smith posted, "a rash of bug reports in multithreaded libraries and applications (occurred) around April 2011--Just after the iPad2 was released. That was the first mass market hardware with a multicore ARM CPU, and it gave a lot of supposedly threadsafe code a workout it had never had before."

The blog comes complete with some psudo-code, C++11 snippets, and the resulting assembly generated by the compiler."

+ - Sociopath Scoffs Internet Infamy->

Submitted by Narnie
Narnie (1349029) writes "Follow up to yesterday's story of a PR rep's lack of professionalism. Kyle Orland provides a follow up interview with Paul Christoforo after a simple email chain escalated into internet infamy. N-Control official response to Paul Chrostoforo's actions can be found here. Kotaku.com even has a whole section devoted to covering the entire ordeal. I for one found myself caught following the news releases and in awe of the combined load forced on penny-arcade's servers from slashdot, reddit, digg, kotaku, and other news sites covering the story."

+ - Vista main culprit in Microsoft layoffs->

Submitted by Narnie
Narnie (1349029) writes "Infoworld.com author Tom Sullivan is suggesting that Vista's performance is so poor that it has forced Microsoft to initiate layoffs.

When Microsoft released its earnings report on Thursday, the company indicated not only that it would lay off up to 5,000 workers or 5 percent of its total headcount but also that software client revenue — as in Windows Vista — sank by 8 percent.
"Windows Vista didn't do well. Based on our data, a lot of clients are skipping Windows Vista," said Neil McDonald, an analyst at Gartner. Indeed, nearly every other major analyst firm found a similar lack of Vista adoption, with Forrester Research likening the OS to the failed New Coke.
