  • online CSS optimizer?

    - by Dand
    Is there an online CSS optimizer equivalent to Googles JavaScript Closure Optimizer. I've found plenty of CSS compressors online, but I'm looking for a CSS optimizer ... where it actually removes redundant/conflicting attributes

  • Books on string algorithms

    - by Max
    There have been numerous posts on string algorithms: http://stackoverflow.com/questions/246961/algorithm-to-find-similar-text, http://stackoverflow.com/questions/451884/similar-string-algorithm, http://stackoverflow.com/questions/613133/efficient-string-matching-algorithm However, no general literature was mentioned. Could anyone recommend a book(s) that would thoroughly explore various string algorithms? The topic which is of special interest is approximate string matching [things like google-offered corrected search string variants :) ]. Thanks a lot for advice.

  • What is a good balance for having developers learn at work

    - by Mel
    So now I am the manager. One of the things I always promised myself I would do is have the other developers focus on learning new stuff. In fact I even want to force them to read a couple books that really helped me learn to program. However now I am also accountable for the product getting finished. I have this vision of everyone reading books instead of working and me getting fired. What is the best way to work learning into the developers schedules, especially for the ones that just don't care to learn. How much time should be spent on learning in a work week?

  • Programmatically determine the relative "popularities" of a list of items (books, songs, movies, etc

    - by Horace Loeb
    Given a list of (say) songs, what's the best way to determine their relative "popularity"? My first thought is to use Google Trends. This list of songs: Subterranean Homesick Blues Empire State of Mind California Gurls produces the following Google Trends report: (to find out what's popular now, I restricted the report to the last 30 days) Empire State of Mind is marginally more popular than California Gurls, and Subterranean Homesick Blues is far less popular than either. So this works pretty well, but what happens when your list is 100 or 1000 songs long? Google Trends only allows you to compare 5 terms at once, so absent a huge round-robin, what's the right approach? Another option is to just do a Google Search for each song and see which has the most results, but this doesn't really measure the same thing

  • Online Hotel Booking System, Simultaneous Booking?

    - by KiiroSora09
    I'm asked to create an online booking system with online payment and I'm wondering what to do in the case when 2 customers booked for the same room(s) at the same time. For Example: At the same time: Customer1 and Customer2 booked for a standard room which only has 1 room available. (The Room availability will display that there is still 1 room available). And then they hit the 'confirm' button at the same time.

    - by howdyworld
    I develop applications using PHP and MySQL. They're not trivial, though they're not too complex. As an example to that I have written an online application to enable football administrators manage the player, competition and judiciary processes. Separately to that I have used Joomla to create websites for small businesses. I'd like to be able to use Joomla as my online application development environment. Is there a way I can use Joomla for that?

  • "Steam needs to be online to update" - 404 fetching *_osx.zip.*

    - by Chris Boyle
    Since yesterday evening, when I launch Steam on OSX, a self-update progress bar appears instead (at 0 of 30MB or so). This bar does not advance, an error dialog appears: Steam needs to be online to update Please confirm your network connection and try again. The app then exits. This happens whether wifi or ethernet or both are connected, and pings to the outside world succeed throughout. If I look at the logs in Console, they are very similar to this example (though that's not mine). Specifically: Success! http://store.steampowered.com/public/client/steam_client_osx?date=718277 [...] Failed! http://cdn.store.steampowered.com/public/client/breakpad_osx.zip.27f59114a86fcd50533e1d7b128f9300947f9969 Failed! http://cdn.store.steampowered.com/public/client/steam_osx.zip.11a99384214805f2dd3be5084ba6be61d662f8ac Failed! http://cdn.store.steampowered.com/public/client/miles_osx.zip.d9fb546541f59c1fdd03962a605236b1021abab8 Requesting the first URL successfully returns some data including the filenames of the latter three, and requesting any of those gives me a 404 (I've tried multiple clients on multiple continents). Searches on Google and Twitter show about 10-20 others having this problem in the past 24 hours, but hardly the angry mob I'd expect if the problem affected all Steam OSX users. Things that have already been tried with no effect: Switching between wifi and ethernet. Killing all Steam processes including ipcserver. Moving the ~/Library/Application Support/Steam/registry.vdf file away. Requesting those URLs with other clients and from other locations. Interesting: that first URL with the date parameter returns the same content even without that parameter (thus would lead to the same 404s) suggesting that the problem is not necessarily specific to coming from a particular currently-installed version of Steam.

  • o2cb thinks ocfs2 cluster is still online, and refuses to shut down

    - by Kendall
    I have a handful of OpenSuSE 11.2 servers that utilize OCFS2 volumes. I've noticed that o2cb can't figure out when the OCFS2 cluster is actually mounted. For example, when I try to shutdown o2cb, after stopping OCSF2, o2cb refuses to shutdown because it thinks OCFS2 is still up! After stopping OCFS2 I try to stop o2cb... hamguy:/dev/disk/by-label # /etc/init.d/o2cb stop Stopping O2CB cluster ocfs2: Failed Unable to stop cluster as heartbeat region still active So I check the status... hamguy:/dev/disk/by-label # /etc/init.d/o2cb status Driver for "configfs": Loaded Filesystem "configfs": Mounted Stack glue driver: Loaded Stack plugin "o2cb": Loaded Driver for "ocfs2_dlmfs": Loaded Filesystem "ocfs2_dlmfs": Mounted Checking O2CB cluster ocfs2: Online Heartbeat dead threshold = 31 Network idle timeout: 30000 Network keepalive delay: 2000 Network reconnect delay: 2000 Checking O2CB heartbeat: Active And double check OCFS2... hamguy:/dev/disk/by-label # /etc/init.d/ocfs2 status Configured OCFS2 mountpoints: /u/conf /u/logs /u/backup /u/client /u/data /u/mdata OCFS2 is clearly down, while o2cb clearly thinks otherwise. The versions of OCFS2 and o2cb are... kendall@hamguy:~> rpm -qa |grep ocfs2 ocfs2console-1.4.1-25.6.x86_64 ocfs2-tools-o2cb-1.4.1-25.6.x86_64 ocfs2-tools-1.4.1-25.6.x86_64 kendall@hamguy:~> rpm -qa |grep o2cb ocfs2-tools-o2cb-1.4.1-25.6.x86_64 What causes this, and is there a way around it? If I try to reboot the machine, it will just sit there forever until your physically power cycle it. That obviously is a bit of a problem. Any insight is appreciated, thank you. Kendall

  • Online computer not responding to pings

    - by mastercork889
    I was doing a bit of scanning on my network lately, knew all the hostnames to each computer connected. But whilst pinging one of them ping returned Request timed out.. This is strange as I know the computer is online and that the computer responds correctly to pinging on a different (enterprise) network. Is there something on the computer, my network, or my computer that is bugging with this? - That's just a sub-question, I don't expect this to be the main answer. The real question: Why does this happen? Why does pinging the IP4 address not work? EDIT : Pinging the Hostname used to default to the IP4 address, but now it defaults to the IP6 address. Why does this happen? But now that it pings using IP6, how come it all of a sudden works? > ping -6 THE_COMPUTER Pinging THE_COMPUTER [lengthy IP6 address] with 32 bytes of data: Reply from [lengthy IP6 address]: time=1ms Reply from [lengthy IP6 address]: time=1ms Reply from [lengthy IP6 address]: time=1ms Reply from [lengthy IP6 address]: time=1ms Ping stats: Sent = 4, Recieved = 4, Lost = 0 (0% loss) But when this is done using IP4 it doesn't work. So there are now two questions: How come IP6 works and not IP4? Why does IP4 not work?

  • VPS goes slow at more than 20 users online at the same time

    - by hachiari
    I have 512 MB VPS (brustable to 1GB) Somehow, the site goes slow when there are about 10 users, and becomes impossible to load at 20 users online at the same time. I wonder what could be the problem for this. The bandwidth connection of the VPS is 1Gbps. Here is some settings in my VPS: KeepAlive Off <IfModule prefork.c> StartServers 7 MinSpareServers 7 MaxSpareServers 10 ServerLimit 64 MaxClients 64 MaxRequestsPerChild 0 </IfModule> my.cnf settings - calculated Max Memory 300MB Output from UNIXBENCH INDEX VALUES TEST BASELINE RESULT INDEX Dhrystone 2 using register variables 376783.7 13429727.4 356.4 Double-Precision Whetstone 83.1 1137.5 136.9 Execl Throughput 188.3 1637.4 87.0 File Copy 1024 bufsize 2000 maxblocks 2672.0 148868.0 557.1 File Copy 256 bufsize 500 maxblocks 1077.0 79430.0 737.5 File Read 4096 bufsize 8000 maxblocks 15382.0 1410009.0 916.7 Pipe Throughput 111814.6 4419722.0 395.3 Pipe-based Context Switching 15448.6 561505.1 363.5 Process Creation 569.3 10272.7 180.4 Shell Scripts (8 concurrent) 44.8 514.3 114.8 System Call Overhead 114433.5 3537373.8 309.1 ========= FINAL SCORE 295.0 I am afraid that the VPS company limit the number of connection to the VPS... is it possible? The server is in Japan, but the site has global traffic (some of the traffic are from countries with low speed connection). Could this be the problem? This is a serious problem :( my site just cant grow if this keeps on happening... please tell me if you have any idea. Thank You, Bryant

  • Listen to music from different sources possible?

    - by hsmit
    I would like to be able to listen to any song I've listened once before. Sometimes I listen to a CD, then to a MP3, a portable music player, ipod, radio channel, online services. I think it must be possible to save an index online of all my music. This index must indicate where the music is stored and ultimately be able to retrieve that song from the location. Is there a service available who accomplishes this?

  • The Oracle Retail Week Awards - most exciting awards yet?

    - by sarah.taylor(at)oracle.com
    Last night's annual Oracle Retail Week Awards saw the UK's top retailers come together to celebrate the very best of our industry over the last year.  The Grosvenor House Hotel on Park Lane in London was the setting for an exciting ceremony which this year marked several significant milestones in British - and global - retail.  Check out our videos about the event at our Oracle Retail YouTube channel, and see if you were snapped by our photographer on our Oracle Retail Facebook page. There were some extremely hot contests for many of this year's awards - and all very deserving winners.  The entries have demonstrated beyond doubt that retailers have striven to push their standards up yet again in all areas over the past year.  The judging panel includes some of the most prestigious names in the retail industry - to impress the panel enough to win an award is a substantial achievement.  This year the panel included the likes of Andy Clarke - Chief Executive of ASDA Group; Mark Newton Jones - CEO of Shop Direct Group; Richard Pennycook - the finance director at Morrisons; Rob Templeman - Chief Executive of Debenhams; and Stephen Sunnucks - the president of Gap Europe.  These are retail veterans  who have each helped to shape the British High Street over the last decade.  It was great to chat with many of them in the Oracle VIP area last night.  For me, last night's highlight was honouring both Sir Stuart Rose and Sir Terry Leahy for their contributions to the retail industry.  Both have set the standards in retailing over the last twenty years and taken their respective businesses from strength to strength, demonstrating that there is always a need for innovation even in larger businesses, and that a business has to adapt quickly to new technology in order to stay competitive.  Sir Terry Leahy's retirement this year marks the end of an era of global expansion for the Tesco group and a milestone in the progression of British retail.  Sir Terry has helped steer Tesco through nearly 20 years of change, with 14 years as Chief Executive.  During this time he led the drive for international expansion and an aggressive campaign to increase market share.  He has led the way for High Street retailers in adapting to the rise of internet retailing and nurtured a very successful home delivery service.  More recently he has pioneered the notion of cross-channel retailing with the introduction of Tesco apps for the iPhone and Android mobile phones allowing customers to scan barcodes of items to add to a shopping list which they can then either refer to in store or order for delivery.  John Lewis Partnership was a very deserving winner of The Oracle Retailer of the Year award for their overall dedication to excellent retailing practices.  The business was also named the American Express Marketing/Advertising Campaign of the Year award for their memorable 'Never Knowingly Undersold' advert series, which included a very successful viral video and radio campaign with Fyfe Dangerfield's cover of Billy Joel's 'She's Always a Woman' used for the adverts.  Store Design of the Year was another exciting category with Topshop taking the accolade for its flagship Oxford Street store in London, which combines boutique concession-style stalls with high fashion displays and exclusive collections from leading designers.  The store even has its own hairdressers and food hall, making it a truly all-inclusive fashion retail experience and a global landmark for any self-respecting international fashion shopper. Over the next few weeks we'll be exploring some of the winning entries in more detail here on the blog, so keep an eye out for some unique insights into how the winning retailers have made such remarkable achievements.
