A common concern with the current crop of Solid State Drives is the performance penalty associated with block-rewriting. The flash memory used on today's SSDs is comprised of cells that usually contain 4KB pages that are arranged in blocks of 512KB. When a cell is unused, data can be written to it relatively quickly. But if a cell already contains some data--no matter how little, even if it fills only a single page in the block--the entire block must be re-written. That means, whatever data is already present in the block must be read, then it must be combined or replaced, etc. with the new additional... Read more...

Italy has been showing BitTorrent no mercy lately. First, Italy shuts down the country's largest BitTorrent tracker site, Colombo-BT.org, a couple of weeks ago; and now it is trying to block country-wide access to The Pirate Bay--the Swedish-based BitTorrent site that claims to be "the world's largest BitTorrent tracker"--by ordering all Italian ISPs to block access to The Pirate Bay. According to TorrentFreak, the initial country-wide blocking of the site was successful: "An insider working at an Internet provider in Italy told TorrentFreak that all the relevant large access ISPs in Italy have...

A recent issue where MSN Messenger and Windows Live were blocking YouTube has now been resolved.  Microsoft has laid the blame on an unnamed partner that is allegedly responsible for blocking unsafe content.  Thankfully the situation has now been resolved and Microsoft is assuring users that there won’t be a repeat of such an issue:"Microsoft did not request to block any of the URLs that were accidentally blocked," it said in the blog. "The blocks were made by our partner as a result of their process to block harmful URLs.  We are still investigating the specific reason our partner made these incorrect... Read more...
Pirate Bay has announced plans to Danish ISP Tele2 over their court ordered block of their web site that began in February.   Pirate Bay set up a sister site with trackers called The Jesper Bay to prove just how ineffectual the block was, and as a result the block was more or less an exercise in futility.“The court case was initiated by the IFPI - the infamous anti-piracy organization that represents the recording industry.  The IFPI later tried to use the “landmark decision” to force Swedish ISPs to do the same, but failed.  In fact, it seems that filtering traffic to The Pirate Bay is actually...

Blockbuster is offering to buy Circuit City. They made the offer privately in February, and made it publicly today; a defacto appeal to Circuit City shareholders to pressure the board to sell.

When Apple formally announced plans for an iTunes rental service it was only inevitable that a conflict between Blockbuster and Apple was to occur.  We weren’t entirely sure how this conflict was going to be waged, but now things are becoming clearer:  Blockbuster is developing a set-top box to compete with the Apple TV.“The product would be an offshoot of Movielink, the online film service Blockbuster acquired last year that allows consumers to watch films licensed from the major studios on their PCs.Delivering movies to TV might be the most audacious attempt yet that Blockbuster is making to...

Need to access older versions of certain Office files and suddenly can't?  Did you install SP3?If you need to access old Microsoft file formats for early versions of Word, Excel, or Powerpoint -- but you've suddenly and dramatically found yourself unable to do so -- there's an intentional reason from Microsoft behind that conundrum, according to a bulletin put out by Microsoft last month.The reason for the unexpected incompatibility is that, by default, the SP3 update, which became available in mid-September, blocks the file formats used by these older desktop productivity tools from Microsoft.Moreover,...

In the wake of the recent allegations that Comcast, the second largest ISP in the U.S., has been stopping or slowing P2P traffic, a new tool has been released that will allow users to discover for themselves if their own ISP is taking similar measures. The tool was developed by Electronic Frontier Foundation, a San Francisco-based nonprofit organization that aims to help users determine if they are the victims of data discrimination.“The new software compares lists of data packets sent and received by two different computers and looks for discrepancies between what one sent and the other actually...

In recent months Comcast has been accused of blocking BitTorrent traffic on more than one occasion and the company has even gone so far as to cut customers off who use an 'excessive' amount of their 'unlimited' bandwidth.On one side of the recently drawn battle lines are the customers who are claiming that Comcast needs to spend more money on infastructure instead of taking such restrictive measures.  On the other side is, of course, Comcast who maintains that their TOS gives them discretion to cut off users whenever they feel like it.  Users have taken their war to local news agencies...

Want to find out if you're dating a player?  Or simply want revenge (as we could see as a possible abuse of this service)?  This could be the service for you, and it's all text message-based.Based on the highly optimistic starting assumption that "people cheat and lie while dating and in relationships," PlayerBlock claims to be the first ever text-based service that enables romance seekers to investigate the dating habits of others (the Web already hosts similar date- and fidelity-tracking sites).PlayerBlock members (who pay $4.99 per month for up to 100 messages) are encouraged to report...

In a move that runs counter to the very concept of Net Neutrality - that all data is treated the same - the Associated Press has found, and confirmed with tests, that Comcast blocks attempts by users to share files online.The interference, which The Associated Press confirmed through nationwide tests, is the most drastic example yet of data discrimination by a U.S. Internet service provider. It involves company computers masquerading as those of its users.If widely applied by other ISPs, the technology Comcast is using would be a crippling blow to the BitTorrent, eDonkey and Gnutella file-sharing...
