Making silicon chips is not easy, requiring hugely expensive fabs, with massive clean-room environments and at every process shrink, the complexity and difficulty of making the things goes up significantly. It looks like TSMC and GlobalFoundries are both having serious yield problems with their 28 nm process nodes, according to Mike Bryant, technology analyst at Future Horizons and this is causing a rash of non-working wafers – to the point of having nothing working with some chip designs submitted for production. It seems that the root cause of these problems are to do with the pressures of bringing products to market, rather than an inherent problem with the technology; it just takes time that they haven't got to iron out the kinks and they're getting stuck: "Foundries have come under pressure to release cell libraries too early – which end up with designs that don't work," Bryant said. In an effort to try and be seen to treat every customer equally, TSMC is attempting to launch ten 28 nm designs from seven companies, but it's not working out too well: "At 45-nm, only NVIDIA was affected. At 28-nm any problems for TSMC will be problems for many customers" said Bryant.
Guru3D reports on a post from NVIDIA tech support on NVIDIA's forums regarding TDR issues (Timeout Detection & Recovery problem (display stopped responding but has successfully recovered)). These problems centre around Battlefield 3 and Windows Media Centre, which NVIDIA can't reproduce, so it looks like the problems may be with specific card models. NVIDIA rep ManuelG posted:
Hot on the heels of our previous story of Apple Macs falling prey to a DDoS trojan, we now have another Mac trojan come on the market, as explained by Sophos. Yes, the Apple platform must indeed be becoming more popular to get this one. It's an unfortunate fact of life that the popularity of any computing platform, including smartphones, can be judged by the number of criminals who will attack it. This little nasty, called OSX/Miner-D or 'DevilRobber', hijacks Mac OS X to perform various tricks, which include minting Bitcoins (the virtual and now virtually worthless currency) stealing usernames and passwords (of course) taking screenshots and stealing the victim's Bitcoin wallet while it's at it, if there is one. And for good measure:
it runs a script that copies information to a file called dump.txt regarding truecrypt data, Vidalia (TOR plugin for Firefox), your Safari browsing history, and .bash_history.So, now the criminals also know about all the sites one has visited, eroding user privacy even more. It looks like this malware has covered all the bases, but wait, there's more.
Finally a fix for the BSOD/disconnect bug that has been plaguing users for months is available for SF-2200 based SSDs. OCZ uses these, has been testing this new firmware for several weeks and now believes that it's fit for release. The new firmware is at version 2.15 for OCZ drives and 3.3.2 for drives that SandForce's standard numbering system. As with any firmware update, it should be used cautiously, all data backed up and perhaps used on a non-mission critical Windows install for a while, for confidence. Note that there may be more unresolved issues and new ones introduced.
