    World, Meet RockMelt

    Hello Interwebs! The rumors are true… starting today, we’re offering access to an early version of RockMelt, a new browser designed around you and how you use the Web.

    RockMelt does more than just navigate Web pages. It makes it easy for you to do the things you do every single day on the Web: share and keep up with your friends, stay up-to-date on news and information, and search. And of course, RockMelt is fast, secure, and stable because it’s built on Chromium, the open source project behind Google’s Chrome browser. It’s your browser – re-imagined and built for how you use the Web.

    If you can stand a few kinks and bugs, sign up for early access, and we’ll get you an invitation as soon as we can. We’d love to know what you think.

    Your World Built into Your Browser

    With RockMelt we’ve re-thought the user experience because a browser can and should be about more than simply navigating Web pages. Today, the browser connects you to your world. Why not build your world right into your browser?

    Your friends are important to you, so we built them in. Now you’re able to chat, share that piano-playing-cat video everyone’s going to love, or just see what your friends are up to, regardless of what site you’re on. Your favorite sites are important to you, so we built them in too. Now you can access them from anywhere, without leaving the page you’re on. And RockMelt will tell you when something new happens.

    Share or tweet links often? Yeah, us too. No more wading through each site’s goofy share widget or copy-pasting URLs. We built sharing directly into the browser, right next to the URL bar. Like a site or story? Click “Share” and BAM – link shared. You can use it on any site to post to Facebook or tweet about it on Twitter. It’s just one click away. That easy.

    Personalized and Backed by the Cloud

    Wherever you go on the Internet, RockMelt makes the Web a personal experience. Because RockMelt is the first browser you log into, it unlocks your Web experience with your Facebook friends, your feeds, your favorite services, even your bookmarks and preferences. RockMelt is also the first browser to be fully backed by the cloud. This means you can access your personal browsing experience from anywhere, and you get quick updates from the people and sites that are important to you.

    Behind the scenes, RockMelt is always working on your behalf. Do you visit the same site 10 times a day, checking for new posts or updates? Well, RockMelt keeps track of all your favorite sites for you, alerting you when a new story comes out, a friend posts new pictures, or a new video is available. And when you open a RockMelt feed, the content is already waiting for you. You can Like, comment, reply, retweet, share - all the actions you’ve come to expect from each service you follow.

    Faster Search

    Last but not least, RockMelt makes search faster. And better. We got tired of clicking back and forth trying to find the right search result. So we made search as simple as leafing through a magazine. With RockMelt, you can use your keyboard to flip through Google search results and pick the one you want. Super fast. Super cool.

    Rock Solid Foundation

    Any intro to RockMelt wouldn’t be complete without recognizing all the tremendous work that came before us—and which we’ve built upon. We’re based on Chromium, the open source project behind Google’s Chrome browser, which in turn is based on WebKit, the open source HTML layout engine used by Apple, as well as a host of other projects from Mozilla and others. These projects, which we contribute to, represent the best browser technology out there. RockMelt wouldn’t be possible without these projects, as well as the open APIs, help and support we’ve received from Facebook, Twitter, and others. We’re proud and deeply grateful to be able to build on the shoulders of these giants. Thanks friends!

    Get Your RockMelt On!

    After two years of work, RockMelt is still a baby. It’s our baby and we’re proud of it, but we’re most excited about what it will grow into. We’ve just scratched the surface of what we want to do. If you’re on Mac or Windows and you don’t mind some kinks and bugs, we hope you’ll sign up for early access and let us know what you think! We are sending out invitations as fast as we can, while making sure our service scales up. We hope you like RockMelt as much as we do. You can follow our blog or our Twitter account or like us on Facebook for updates. Happy browsing!

  5. How to Win a Chess Game Fast

    in Off-topic

    Posted · Edited by Fi8sVrs

    Many people believe that chess is the ultimate game. It requires skill, strategy and the ability to think ahead. There are some moves, however, that can bring crushing defeat to an opponent very early on, sometimes before they even know what hit them. This guide provides step by step instructions on how to execute a classic chess strategy that will defeat inexperienced players in just four short moves.

    Instructions

    Things You'll Need:

    • Chess board
    • Opponent

    1. win-chess-game-fast-1.1-120X120.jpg

    Move the Pawn that is situated in square E2, directly above the King. You can move this Pawn forward either one or two spaces. It does not matter which you choose, however, moving only one space will provide a better defense in the event that you are matched against an experienced player who will try to reverse this strategy on you.

    2. win-chess-game-fast-1.2-120X120.jpg

    Know that after your initial move, it will be your opponent's turn. Very few moves your opponent can make will change your outcome at this stage. For simulation purposes, assume that the other player leads out with their Queen's Knight. Make your second move and move your Queen three spaces to space F3. In the example given, an inexperienced player may be hoping that you will be foolish enough to take the Knight with your Queen and will not likely anticipate your next move.

    3. win-chess-game-fast-1.3-120X120.jpg

    Let your opponent make a second move. For simulation purposes, assume that they move their Pawn forward to E5 in an attempt to apply pressure to your Queen. This is a common move and one that you may really encounter. After the other player moves it is your turn once again. They will be expecting you to use your Queen, but move your King's Bishop instead. Move the Bishop four spaces to space C4.

    4. win-chess-game-fast-1.4-120X120.jpg

    Let your opponent make a third move. Assume that they move their Pawn forward an additional space in hopes of taking your Queen. Now it is your fourth and final move. Move your Queen all the way up to space F7, taking the opponent's Pawn and placing them in Check Mate. You have just won the chess game in four simple moves.

    Tips & Warnings

    • This strategy may not work every time. A player may see this coming, or inadvertently move a piece that throws a wrench in the monkey works. It is still good to try the first time you play someone so that you will have a feel for how advanced your opponent is.
    • Inexperienced chess players usually fall for this move very easily. Be warned, however, that experienced players will often consider it to be a cheap shot and will try very hard to take you down if they see you attempting this tactic.

  8. Logic behind Arabic Numbers

    in Off-topic

    Posted

    The number system what we use today (1,2,3,4,5…) is called Arabic Numbers System. We also have Roman Numbers System (I, II, III, IV, V, …) which is rarely being used.

    Have you ever thought WHY One is 1, Two is 2, Three is 3 … and so on?

    It is all because of Angles. Yes, it is the number of angles in each letter.

    The following image has ancient Arabic numbers. All the angles that are formed in these letters are mentioned by the letter o.

    The number of angles gives meaning to each letters.

    Number 1 has one angle

    Number 2 has two angles

    Number 3 has three angles

    Quite the dollar amount. This is the new LSI SLP-300 acceleration card, intended for a different set of purchasers that me and… well probably you too. It’s a low-profile solid state storage card aimed directly at big companies hoping to keep performance but reduce clutter. This bad boy delivers data efficiency to the tune of hundreds of hard drives while consuming less than 25W of power, claims LSI. That sounds quite amazing, says we. Sounds quite amazing indeed.

    LSI_PCIe-580x353.jpg

    By the numbers, you’d need 400+ mechanical hard drives and 36U of rack space, PLUS more than 300 times the power you’d usually use to achieve the same result. If you happen to get your hands on one of these, you can bet you’ll get up to 240,000 sustained IOPS and 300GB of SLC solid state storage capacity, all of this in a teeny tiny card (the one you see above.) You can plug it directly into your standard 8 lane PCI-Express Generation 2 server slot. Once plugged in, it can take up to 1,400MB/s of throughput with access latency of under 50 microseconds. That rocks. That rocks so very much. Read the entire press release below:

    LSI Bolsters Channel Portfolio with PCI Express Solid-State Storage Card for Application Acceleration

    New LSI™ WarpDrive™ plug-and-play I/O acceleration card dramatically improves application performance while reducing rack space, power and cooling costs

    MILPITAS, Calif., November 16, 2010 – LSI Corporation (NYSE: LSI) today introduced in the channel the LSI WarpDrive™ SLP-300 acceleration card, a PCI Express (PCIe®) card offering performance up to 240,000 sustained IOPS and 300GB of SLC solid-state storage capacity within a low profile form factor. The WarpDrive card can help customers accelerate application performance, reduce energy costs and eliminate racks of storage by delivering the I/O performance of hundreds of hard disk drives while consuming less than 25 watts of power.

    ”The LSI WarpDrive card sets a new standard for data center efficiency by providing IT administrators with previously unattainable levels of performance while helping to reduce operational and capital expenditures,” said Brent Blanchard, director of worldwide channel sales and marketing, LSI. “The WarpDrive card complements the LSI CacheCade™ and FastPath™ solid-state storage acceleration solutions, providing our channel partners with a one-stop shop to address the performance, deployment and integration requirements that high-performance applications and dense computing demand.”

    The low-profile, half-length WarpDrive card plugs into a standard 8 lane PCIe Gen 2.0 server slot and is designed to deliver high performance with low latency and a low CPU burden independent of main memory size. It offers system builders, system integrators and their end customers a cost-effective, plug-and-play solution for maximizing the transactional I/O performance of applications such as Web serving, data warehousing, data mining, professional video and high-performance computing.

    A WarpDrive card can sustain up to 1,400MB/s of throughput, with reliable and consistent performance across both sequential and random reads and writes. It delivers up to 240,000 4K read IOPS and up to 200,000 4K write IOPS, with access latency of less than 50 microseconds. To achieve equal performance on a write IOPS basis utilizing hard disk drives would require over 400 drives, 36U of rack space and consume more than 300 times the power.

    “The LSI PCIe-based WarpDrive card offers simple, effective, and affordable application acceleration for enterprise servers,” said Bob Farkaly, director of marketing, Storage System products for Exar. “Utilizing two WarpDrive cards combined with Exar’s BitWackr ™solution, we measured an aggregate performance of 1,028 MB/second, which is almost twice the speed we were able to achieve with other PCIe-based flash products.”

    “Schooner’s MySQL and NoSQL solutions combined with the LSI WarpDrive card provide industry-leading performance for database and key-value stores, delivering over 9x performance throughput increase relative to hard drive configurations and over 3x performance throughput increase relative to alternative PCIe flash-based solutions,” said Dr. John Busch, founder and CTO, Schooner Information Technologies. “Beyond raw IOPS and latency performance, we are very impressed with the LSI WarpDrive card’s performance stability, observing negligible performance variance over time. Also, the LSI WarpDrive card’s very low overhead consumption of server processor and DRAM memory resources enables even higher performance by leaving these resources available for useful application processing and data caching.”

    The WarpDrive card utilizes industry-standard and widely deployed LSI SAS software drivers to provide channel partners with simple integration and management using existing SAS infrastructure. It features the LSISAS2008 6Gb/s SAS I/O controller and is based on the enterprise-proven LSI Fusion-MPT™ architecture. The WarpDrive card is bootable, has no external power requirement and installs as a single drive with no user configuration required. The WarpDrive card helps to ensure high reliability with a management infrastructure offering extensive monitoring, including health, error rate and drive failure.

    The WarpDrive card builds upon LSI enterprise-level experience in the design, manufacture and support of advanced server and storage solutions. The WarpDrive card is designed to provide system integrators and system builders with a robust and stable solution with assured interoperability and a low-risk path to market. The WarpDrive card also helps to minimize hardware requirements, reducing initial investment costs and eliminating points of failure for greater overall system reliability.

    Price: $11,500
