CurtMonash writes "Web analytics databases are getting even larger. eBay now has a 6 1/2 petabyte warehouse running on Greenplum — user data — to go with its more established 2 1/2 petabyte Teradata system. Between the two databases, the metrics are enormous — 17 trillion rows, 150 billion new rows per day, millions of queries per day, and so on. Meanwhile, Facebook has 2 1/2 petabytes managed by Hadoop, not running on a conventional DBMS at all, Yahoo has over a petabyte (on a homegrown system), and Fox/MySpace has two different multi-hundred terabyte systems (Greenplum and Aster Data nCluster). eBay and Fox are the two Greenplum customers I wrote in about last August, when they both seemed to be headed to the petabyte range in a hurry. These are basically all web log/clickstream databases, except that network event data is even more voluminous than the pure clickstream stuff."

Meneguzzi writes "Having stuck with wired mice for years, I have recently been impressed by a couple of cordless mice I've used on other people's computers so much that I now want to buy one to use with my Mac Book Pro. However, while shopping around for the perfect cordless laptop mouse I was stuck with the question of whether to go for a bluetooth mouse or one of the many proprietary cordless mice with tiny USB receivers. To my surprise, there seems to be little literature systematically comparing these two options for attributes like precision, battery life (both for the mouse and the laptop), RF interference, and whatnot. As a Mac user, bluetooth has the advantage that it won't take up a USB port, and (in theory), would consume less battery than a USB port, but I wonder if this is actually true in practice. On top of that, I noticed that there are far fewer (and less fancy) options for Bluetooth mice than there are for proprietary cordless ones. Logitech, for instance, has a very basic Bluetooth Mouse, while its proprietary options are much fancier. So I was wondering what are the experiences from Slashdotters on this particular type of hardware, and any recommendations."

mighty7sd writes "I am about to be released from my contract with Time Warner for my home internet service, and I am evaluating alternatives to my current cable modem setup. I would love to use AT&T U-Verse or Verizon Fios, but they are not available in my area. I have a good idea of the costs and limitations of Cable and DSL service, so I am considering using mobile broadband for my home internet connection. Most providers seems to cap the connection at 5 GB of data transfer per month. I am a relatively heavy internet user using streaming video and a web server, so I need decent down/upload speeds and a large data transfer cap. Has anyone in the /. community had a good experience using mobile broadband cards at their home, specifically with lots of streaming video or a home server? What has happened if you have gone over your data transfer limit? Cricket Wireless is available in my area for $40 per month with 'unlimited' service, but I am skeptical that it is truly reliable and unlimited. I also found products that act as a WiFi router for mobile broadband services, but it seems that this is against most carriers TOS. Can they really detect these, and are they comparable to a wired broadband router?"

g2 in the desert writes "I live in a small rural community in the US Southwest, where broadband service varies from decent but very expensive, to lousy but less expensive. Now that the Federal Communications Commission has approved the use of the soon to be vacated White-Space Spectrum, I'm interested in helping the community build its own local Internet service, providing villagers another choice. Does anyone know what companies will be manufacturing hardware that will be required to utilize this spectrum, and what steps need to be taken in order to be in compliance with any FCC rules and regulations?"

r3lody writes "Styling Web Pages with CSS: Visual QuickProject Guide, by Tom Negrino and Dori Smith, helps the beginning web designer learn how to use CSS in a simple, easy-to-follow format. This being my first exposure to one of the Visual QuickProject Guides by Peachpit Press, I was both pleased and disappointed when I received this slim volume. I was pleased in the presentation and clear descriptions given to each aspect of Cascading Style Sheets (CSS). I was disappointed in the brevity of the text, and the lack of downloadable materials to use to follow the examples in the book." Read below for the rest of Ray's review.

Frequent Slashdot contributor Bennett Haselton writes with his take on the recent Time Warner Cable fiasco: "Net Neutrality crusaders at FreePress.net recently called attention to Time Warner's plan (later rescinded) to impose fines on users for going over bandwidth limits. I agree generally, but I think this is easily confused with the reasoning in favor of Net Neutrality, and it's important to keep the arguments separate." Read on for the rest of Bennett's thoughts.

david_adams writes "All the recent talk about various polls and elections being pranked or hijacked, serious and silly alike, prompted me to write an article about the technical realities behind online polling, and the political fallout of ever becoming subject to online voting for serious elections. Even if we were to be able to limit voting to legitimate, legal voters, the realities of social networking and the rise of Internet-based movements would dramatically alter the political landscape if online voting were to become commonplace."

Vigile writes "With the release of AMD's latest budget graphics card, the Radeon HD 4770, the GPU giant is bringing a lot of technology to the table. The card sports the world's first 40nm GPU (beating out CPUs to a new process technology for the first time), GDDR5 memory, and 640 stream processors, all for under $100. What is even more interesting is that as PC gaming has evolved it appears that a $99 graphics card is all you really need to play the latest PC titles — as long as you are comfortable with a resolution of 1920x1200 or below. Since so few PC gamers have screens larger than that, could the world of high-end PC graphics simply go away?"

nandemoari alerts us to news over at DSLReports that Cablevision will be offering subscribers 101-Mbps download service, a new US record. That's fast enough to download an HD movie in less than 10 minutes. The package, known as "Ultra," will launch on May 11 and will cost $99.95 a month. Upload speed is 15 Mbps and there are no monthly limits. Cablevision is also doubling the speed of its Wi-Fi service, which is available free to subscribers using hotspots across the Northeast. "...the company will be launching a new 'Ultra' tier on May 11. The new tier features speeds of 101Mbps downstream and 15Mbps upstream for $99.95 a month. That's an unprecedented amount of speed at an unprecedented price, suggesting that Cablevision just took the gloves off in their fight against Verizon FiOS. ... Cablevision spokesman Jim Maiella confirmed for me that the $99.95 price is unbundled, and the new tier does not come with any kind of a usage cap or overage fees."

yahyamf writes "I have a lot of free educational content in the form of audio lectures and text, which I'd like to translate into as many languages as possible. I would also want to transcribe the audio and create audiobooks from the text. There are already several volunteers willing to contribute, but I need some web based software to manage all the work. Facebook is already doing something like this, but it is only for their content. I've also looked at Damned Lies, which is part of the Gnome project, but it doesn't seem to handle audio. Are there any other open source translation projects out there that I can customize and build upon?"

marpot writes "Does your school/university check your homeworks/theses for plagiarism? Nowadays, probably Yes, but are they doing it properly? Little is known about plagiarism detection accuracy, which is why we conduct a competition on plagiarism detection, sponsored by Yahoo! We have set up a corpus of artificial plagiarism which contains plagiarism with varying degrees of obfuscation, and translation plagiarism from Spanish or German source documents. A random plagiarist was employed who attempts to obfuscate his plagiarism with random sequences of text operations, e.g., shuffling, deleting, inserting, or replacing a word. Translated plagiarism is created using machine translation."

Hugh Pickens writes "The Electronic Frontier Foundation has filed suit against Apple to defend the First Amendment rights of BluWiki, a noncommercial, public Internet 'wiki' site operated by OdioWorks. Last year, BluWiki users began a discussion about making some Apple iPods and iPhones interoperate with software other than Apple's iTunes. Apple lawyers demanded removal of the content (pdf) sending a letter to OdioWorks, alleging that the discussions constituted copyright infringement and a violation of the DMCA's prohibition on circumventing copy protection measures. Fearing legal action by Apple, OdioWorks took down the discussions from the BluWiki site but has now filed a lawsuit to vindicate its right to restore those discussions (pdf) and seeking a declaratory judgment that the discussions do not violate any of the DMCA's anti-circumvention provisions, and do not infringe any copyrights owned by Apple. 'I take the free speech rights of BluWiki users seriously,' said Sam Odio, owner of OdioWorks. 'Companies like Apple should not be able to censor online discussions by making baseless legal threats against services like BluWiki that host the discussions.'" Random BedHead Ed adds ZDNet quotes EFF's Fred von Lohmann, who says that this is an issue of censorship. 'Wikis and other community sites are home to many vibrant discussions among hobbyists and tinkerers. It's legal to engage in reverse engineering in order to create a competing product, it's legal to talk about reverse engineering, and it's legal for a public wiki to host those discussions.'"

RyuuzakiTetsuya writes "According to Kotaku, Marvel vs. Capcom 2 is making its way to the PS3 and the Xbox 360. It's based on the Dreamcast code, and it includes Online play and widescreen support. A demo will be available Thursday on the Playstation Network, and the full game will retail for $15 on each of the respective online services. A gameplay trailer is available as well."

A wave of new companies are springing up to offer such things as virtual cemeteries, alerts to remind loved ones about the anniversary of your death, and even email services that send an alert to your sinful relatives in danger of being left behind when the Rapture carries you away. "People have a desire to perpetuate not only for themselves, but for their loved ones, the story of their lives, and technology has all these new great ways of doing that," said John McQueen, owner of the Anderson McQueen funeral home.
