"Buried deep in a pile of slashdot comments, Matthew Dillon of DragonFly gives a detailed assessment of the Intel Core bugs. While a lot of news sites and bloggers were quick to dismiss the issue as inflated, Dillon's comments provide a much closer look at the actual issues."

Theo contributed a lot to the SPARC port of NetBSD/OpenBSD; he is a de-facto spokesman for OpenBSD, so he basically says what the other ~80 developers think (including those who do the very low-level work).
Theo definitely doesn't poll the developers before he opines.
Matt used to design hardware and operating systems from scratch; he is a VM guru (so he has authority to talk on MMUs); he worked on nearly every part of the DragonFlyBSD kernel, including low-level stuff.
He never designed a processor from scratch, nor, as far as I know, has he ever worked on a processor bringup.
They certainly have way more authority to judge hardware errata than you or I.
The whole point of my comments on this thread is that "authority" is meaningless in discussions like this.
I have been involved in the design of processors from scratch, I have done low level bringup on very complex processors, and I have dealt with far worse errata than those that Theo is complaining about. However, I would not want you to take my word for this.
Theo has offered no arguments to support his claims, only claims. Matt has offered arguments, but others have offered counters. You should forget Matt's credentials and compare his arguments to those being offered in rebuttal.
If you understand the field, then you will realize that Matt has overreacted in this instance, and Brandon has done a good job of addressing his concerns.
"So in summary... Google has pulled the plug on support on a protocol they've helped popularize, after years of promising interoperability, for reasons that are dubious at best, and in a way that leaves people who don't jump to the new Hangouts app unable to talk to their contacts without any feedback that their IMs aren't getting through... And they've done that with no warning to anyone. I imagine there's a bunch of people out there wondering where some of their buddies have gone, or why their messages aren't getting responses, because this isn't documented anywhere." Google really messed this up. Such a dick move.
The Tizen Greek Community has some screenshots of a very recent build of Tizen running on a Samsung GT-i8800. It looks wholly unremarkable.Joint statement to The Next Web from Microsoft and Google: "Microsoft and YouTube are working together to update the new YouTube for Windows Phone app to enable compliance with YouTube's API terms of service, including enabling ads, in the coming weeks. Microsoft will replace the existing YouTube app in Windows Phone Store with the previous version during this time." Good to know these children stopped acting like little pricks. Can we have full Google support in Windows 8 now, please?
Yahoo is acquiring Tumblr, the microblogging and social networking website, for $1.1 billion USD. Tumblr offers little revenue but lots of eyeballs if Yahoo can monetarize them. Now Yahoo is bidding for Hulu, the streaming video service. After years of ineffective responses while Google, Facebook, and others took large chunks of the online advertising market, Yahoo is fighting back. Can Yahoo reignite the momentum it had at the turn of the century? What do you think?
"Sources have described iOS 7 as 'black, white, and flat all over'. This refers to the dropping of heavy textures and the addition of several new black and white user interface elements." I couldn't be happier.
"Ilja van Sprundel, a security researcher with IOActive, has discovered a large number of issues in the way various X client libraries handle the responses they receive from servers, and has worked with X.Org's security team to analyze, confirm, and fix these issues."
"Google is facing a new antitrust probe by the U.S. Federal Trade Commission into whether the company is using its leadership in the online display-advertising market to illegally curb competition, people familiar with the matter said." Sucks to be Google today, apparently."In the midst of the major press blitz surrounding its annual I/O Conference, Google dropped some unfortunate news about its instant messaging plans. In several places around the web, the company is replacing the existing 'Talk' platform with a new one called 'Hangouts' that sharply diminishes support for the open messaging protocol known as XMPP (or sometimes informally Jabber), and also removes the option to disable the archiving of all chat communications. These changes represent a switch from open protocols to proprietary ones, and a clear step backward for many users." That's why I always say: only suckers trust companies."The wave of departures is a sign of internal struggle, but amidst all the bad news, there is a glimmer of hope. According to an anonymous HTC executive cited by WSJ, the crucial HTC One is selling 'pretty good so far'. The executive revealed that HTC sold about five million One units since launch, a performance that is deemed encouraging. However, sales have been limited by the persisting supply issues that still plague the production of the HTC One." Finally some good news for HTC. Five million units amidst supply constraints is very impressive.
"Sony gave the PS4 50% more raw shader performance, plain and simple (768 SPs @ 800MHz vs. 1152 SPs & 800MHz). Unlike last generation, you don't need to be some sort of Jedi to extract the PS4's potential here. The Xbox One and PS4 architectures are quite similar, Sony just has more hardware under the hood. Weâll have to wait and see how this hardware delta gets exposed in games over time, but the gap is definitely there. The funny thing about game consoles is that itâs usually the lowest common denominator that determines the bulk of the experience across all platforms. On the plus side, the Xbox One should enjoy better power/thermal characteristics compared to the PlayStation 4. Even compared to the Xbox 360 we should see improvement in many use cases thanks to modern power management techniques." AnandTech does its usual in-depth thing.

> Neither Theo nor Matt have much direct experience in bringing up OSes on processors, and so neither are more qualified judges of hardware errata than anyone here is likely to be.
