The Many Paths To Data Corruption 121

Posted by Zonk on Friday September 14, 2007 @05:45PM from the luke-alan-cox-is-your-guru dept.

Runnin'Scared writes "Linux guru Alan Cox has a writeup on KernelTrap in which he talks about all the possible ways for data to get corrupted when being written to or read from a hard disk drive. This includes much of the information applicable to all operating systems. He prefaces his comments noting that the details are entirely device specific, then dives right into a fascinating and somewhat disturbing path tracing data from the drive, through the cable, into the bus, main memory and CPU cache. He also discusses the transfer of data via TCP and cautions, 'unfortunately lots of high performance people use checksum offload which removes much of the end to end protection and leads to problems with iffy cards and the like. This is well studied and known to be very problematic but in the market speed sells not correctness.'"

Speaking of Google, does anyone else find it kind of funny that the number 1 AOL search term for the timeframe is google? I got a chuckle out of it.

Who Needs a Satellite Dish When You Have a Wok? 250

An anonymous reader writes "Why pay $20,000 for a commercial link to run your television station when a $10 kitchen wok from the Warehouse is just as effective? This is exactly how North Otago's newest television station 45 South is transmitting its signal from its studio to the top of Cape Wanbrow, in a bid to keep costs down."

Sony Says Nobody Will Ever Use All the Power of a PS3 581

Tighthead Prop writes "Sony executive Phil Harrison has made some brash comments about the Cell processor and the PlayStation 3. Harrison says that the current PS3 game lineup is using less than half of the machines power, adding that 'nobody will ever use 100 percent of its capacity.' Is he right? 'The major reason Harrison wants to hype up the "unlimited" potential of the PS3's architecture is to downplay comparisons between games running on Sony's console and Microsoft's Xbox 360. The two systems are not completely dissimilar: they both contain a PowerPC core running at 3.2 GHz, both have similarly-clocked GPUs, and both come with 512 MB of RAM.'"

Microsoft's IE7 Search Box Bugs Google 803

tessaiga writes "The New York Times reports that Google is crying foul over a new IE7 search box feature that defaults to MSN Search. Although the feature can be modified to use Google or other search engines, Google asserts that "The best way to handle the search box [...] would be to give users a choice when they first start up Internet Explorer 7." Google goes on to assert that the move "limits consumer choice and is reminiscent of the tactics that got Microsoft into antitrust trouble in the late 1990s". I notice that in my version of Firefox the search box defaults to Google, and that the pulldown menu of pre-entered options doesn't even include MSN Search, but Google seems to have been oddly quiet on that front for the many years prior to IE7 that Firefox has made this feature available."
