Submission + - Cache of the titans: Are SSD accelerators any good? (extremetech.com)

MrSeb writes: "When solid-state drives first broke into the consumer market, there were those who predicted the new storage format would supplant hard drives in a matter of years thanks to radically improved performance. In reality, the shift from hard drives (HDDs) to SSDs has thus far been confined to the upper end of the PC market. For cost-conscious buyers and OEMs, the higher performance they offer is still too expensive and the total capacity is insufficient. SSD cache drives have emerged as a means of addressing this situation. They are small, typically containing between 20-60GB of NAND flash and are paired with a standard hard drive. Once installed, drivers monitor which applications and files are accessed most often, then cache those files on the SSD. It can take the software 1-2 runs to start caching data, but once this process is complete, future access and boot times are significantly enhanced. ExtremeTech compares the effect of SSD cache solutions — Intel Smart Response Technology, and Nvelo Dataplex — on the performance of a VelociRaptor, and a slow WD Caviar drive. The results are surprisingly positive."

Submission + - The world's greatest competitive programmer (technologyreview.com)

An anonymous reader writes: Technology Review profiles Petr Mitrichev, who has since 2005 dominated the world of competitive programming, a little known sport where competitors furiously code for five hours in pursuit of glory and cash prizes worth tens of thousands of dollars. Mitrichev now works for Google, and competes only for leisure, but is still ranked number one. Many large tech companies, such as Facebook and Google, now sponsor and pay close attention to competitive coding contests, seeing them as a place to recruit new talent.

Submission + - SkyDrive account suspensions prove you can't trust cloud storage (blogspot.ca) 1

quantr writes: ""When cloud storage services started appearing they proved very popular, with Dropbox being the standout example of how easy and useful files in the cloud can be. The convenience of having an online storage pool you can access from any and all devices is great, and such services are only going to get more popular as we consume ever more digital content.

There is a problem, though. Each service has its own set of terms and conditions, and if you violate the rules, you could see your account suspended and access to your files cut off. This has recently been demonstrated by Megaupload being taken offline, but in that case all users lost their files, not just a few individuals.
This problem gets worse if the cloud storage service you use is linked to other services. One example of this is Microsoft’s SkyDrive, which is accessed through a Windows Live login that is also used for accessing Hotmail, Messenger, and Xbox Live. If your account gets suspended, you lose access to all those services.""
