• How to organise projects with dependencies on BitBucket?

  - by Timwi

  Both Mercurial and BitBucket make one fundamental assumption: 1 repo = 1 project. If I have a project that has a dependency (a library) which is shared by many projects, this assumption gets in the way. Now it is no longer possible to have a separate BitBucket page for each project while still being able to commit atomic revisions to multiple projects. If I put all the projects into one repo, they all become one “project” on BitBucket. If I put them in separate repos, it is no longer possible to know which version of the library project was in use at revision X of a dependent project. How is this situation normally solved on BitBucket, or is there explicitly no support for this common scenario?

• Is there a way to disable a particular pci port

  - by mxdog

  I have a MB with 2 nics on it. a switch burned up and took out one of them. there is no way to turn them off individually in the bios. is there a way to turn off one of the ports. unmap it,unbind it, power it down so the system doesnt see it at after boot. they are mapped as 0000:02.08.0 and 0000:02.08.1 I want to turn the second one off somehow. Since they both use the same driver, blacklisting the module will take out both of them. Normally I would just live with it but it seems there should be a way to do that like in windows (gasp)--just disable it. I Actually have the exact same problem on another comp running XCP so this will be a 2fer if it gets figured out. the OS is 12.4 lts server with xen on it. THX

• How to prevent Gnome desktop from crashing?

  - by nixnotwin

  I have ubuntu 10.10 32bit running on my Asus EEEPC 1005PX. I am experiencing frequent desktop crashes. When I turn on my netbook at least once in 5 times the defualt ubuntu theme disapears and the classic gnome theme appears. Many times while doing some work, the desktop crashes and the CLI gets shown, and after a few seconds the login screen appers. I am not using any widgets or dock bars, I just have a single gnome panel with default menus. The crashes also happen when using the default bundled ubuntu apps. Is there any way to avoid these crashes?

• Using PHP Redirect Script together with Custom Fields (WordPress)? [on hold]

  - by Alex Scherer

  I am currently trying to make yoast's link cloaking script ( Yoast.com script manual // Github Script files ) work together with the Wordpress plugin Advanced Custom Fields. The script fetches 2 values (redirect id, redirect url) via GET and then redirects to this particular URL which is defined in a .txt file called redirects.txt I would like to change the script, so that I can define both the id and redirection URL via custom fields on each post in my WP dashboard.. I would be really happy if someone could help me to code something that does the same as the script above but without using a redirects.txt file to save the values but furthermore gets those values from custom fields. Best regards ! Alex

• Open XML at TechEd 2010

  Open XML was a big part of my first session at TechEd 2010 called, "Office 2010: Developing the Next Wave of Productivity Solutions". The thing that gets the biggest reaction is the Open XML SDK 2.0 "Productivity Tool"-- especially the ability to reflect over an Office document to produce C# code that will produce the target document. Here's the scenario: I have a Word document (Excel spreadsheet, PowerPoint deck) that a user produced manually. I want to be able to produce that same document...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Page Load Time - "Waiting on..." taking ages. What part of page request process is hung?

  - by James

  I have a new cluster site running on Magento that's on a development server that is made up of 2 x web servers and 1 x database server. I have optimized the site in all areas I know (gzip, increasing php memory limits, increasing database memory limits etc) but sometimes the page loading gets stuck on 'waiting for xxx.xx.xx.xxx' (Chrome and other broswers, chrome just shows it that way). It can sit there for 40 + seconds, sometimes it just never loads and I close it in frustration. What part of the page loading process is this hung at? Is it a server issue, database issue, platform issue? I need to know where to start or whether to push the hosting provider about it.

• Constructive ways to answer "What was your most challenging project? and why?"

  - by tau

  I am asked this question many times in the interviews. What was your most challenging project -- and why? I get confused about which project to tell them and why some project would look challenging or non-challenging. What are they looking for in the answer? Any software is a challenge before it gets started and it becomes a normal software engineering task after it has finished. All softwares I made were challenging until they got finished. Do I misunderstood the word "challenge"? What's wrong in my thinking? What's an appropriate and constructive way to approach this question?

• Input Signal Out of Range 1920x1080

  - by Zach

  I've recently installed Ubuntu 12.04 on my computer. Now, every time I boot and when I shut down, my monitor goes blank and says "Input Signal Out of Range - Change Setting to 1920x1080 60Hz." Once the computer gets to the login screen, it's okay again. This problem also happens when I try to open any 3d app. My graphics card is NVIDIA GEforce 6150 SE. I tried updating the drivers, but it broke everything and I had to reinstall Ubuntu. Any help?

• Sync csv file using nodejs

  - by Amit Dugar

  There is a remote csv file that gets updated every second or so. I need to download it(on a Windows machine) ONCE and always sync local file with the remote one. Obviously, downloading the whole file every time is not an option. I need to download only the changes.(something like rsync, rdiff-backup) I searched quite a bit but could not find how I can do this. I am sort of new to nodejs and am using this app as an opportunity to expand my nodejs skills. Also, I am planning to use nodejs and to package it using node-webkit(https://github.com/rogerwang/node-webkit)

• Can't set 1280x1024 with Nvidia Geforce 8400 GS

  - by torbengb

  I've just installed 10.04 LTS using the Windows installer. The system hangs during boot; the splash screen is frozen and it accepts neither Ctrl+Alt+F2 nor Ctrl+Alt+Del, only a hard reset. (I'm a linux noob.) When I edit the default Grub boot option to omit quiet splash, it gets to the point saying * setting sensors limit [OK] _ and there it stays. I can only get to the desktop using the Grub recovery boot option, of course with a lower resolution (800x600) but everything else seems to work fine. As I said, this is a new install. The only thing I've done is to use the Update Manager to get everything up to date, and activate the newest Nvidia driver using the "Hardware drivers" window. I had a similar problem when I installed 9.04 a year ago, and at that time posted this question with an answer that worked - this doesn't work with 10.04. Running nvidia-xconfig to create a new xorg.conf didn't fix it either (while in Recovery boot).

• Adwords: Is there a drawback to setting a really high CPC to learn what works faster?

  - by Rob Sobers

  I'm toying with increasing my max CPC really high on all my keywords so ensure my ad gets shown in the top spot on page one in order to draw more clicks. I think this will be a good way to quickly figure out whether the ads I'm writing have a decent CTR and, more importantly, whether the landing pages I'm building are converting. Since I can set a max daily budget for my campaign, I won't risk breaking the bank. I can't think of any drawbacks, personally. Am I missing any?

• Tip #15: How To Debug Unit Tests During Maven Builds

  - by ByronNevins

  It must be really really hard to step through unit tests in a debugger during a maven build.  Right? Wrong! Here is how i do it: 1) Set up these environmental variables: MAVEN_OPTS=-Xmx1024m -Xms256m -XX:MaxPermSize=512mMAVEN_OPTS_DEBUG=-Xmx1024m -Xms256m -XX:MaxPermSize=512m  -Xdebug (no line break here!!)  -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=9999MAVEN_OPTS_REG=-Xmx1024m -Xms256m -XX:MaxPermSize=512m 2) create 2 scripts or aliases like so:  maveny.bat: set MAVEN_OPTS=%MAVEN_OPTS_DEBUG% mavenn.bat: set MAVEN_OPTS=%MAVEN_OPTS_REG%    To debug do this: run maveny.bat run mvn install attach your debugger to port 9999 (set breakpoints of course) When maven gets to the unit test phase it will hit your breakpoint and wait for you. When done debugging simply run mavenn.bat Notes If it takes a while to do the build then you don't really need to set the suspend=y flag. If you set the suspend=n flag then you can just leave it -- but only one maven build can run at a time because of the debug port conflict.

• Can't print, CUPS package corrupted and hangs on re-install

  - by Little Bobby Tables

  When I upgraded to Ubuntu 10.4 (Maverick), the upgrade process got stuck on the post-installation of the CUPS package. I had to kill processes and run several forced updates before I could finally get regular updated. Ever since I can't print - The printed file gets messed up and crashes the printer. I also can't re-install CUPS, as each time the installation hangs and I have to kill it before it completes. I tried to find a workaround for this problem, but in vain. Does anyone know how to bypass this? Or at least why can the post-installation hang, and how to re-install a problematic package? Some system specs and other hints: Dell D630 laptop running Ubuntu 10.4, Gnome desktop, standard LAN network, printing to an LPD server. Everything worked fine on 9.10. Also, the printed files themselves are not corrupted. The problem does not seem to be Evince-specific, but common to all printouts.

• Changing DisplayMode seems not to update Input&Graphic Dimension

  - by coding.mof

  I'm writing a small game using Slick and Nifty-GUI. At the program startup I set the DisplayMode using the following lines: AppGameContainer app = new ... app.setDisplayMode( 800, 600, false ); app.start(); I wrote a Nifty-ScreenController for my settings dialog in which the user can select the desired DisplayMode. When I try to set the new DisplayMode within this controller class the game window gets resized correctly but the Graphics and Input objects aren't updated accordingly. Therefore my rendering code just uses a part of the new window. I tried to set different DisplayModes in the main method to test if it's generally possible to invoke this method multiple times. It seems that changing the DisplayMode only works before I call app.start(). Furthermore I tried to update the Graphics & Input object manually but the init and setDimensions methods are package private. :( Does someone know what I'm doing wrong and how to change the DisplayMode correctly?

• Why using the word "mechanism" in CS?

  - by Nick Rosencrantz

  I'm not sure about the usage of the word "mechanism" when in fact most of the time what is meant is an algorithm. For instance there's talk about Java's "thread-scheduling mechanism" - why not call it an algorithm and why borrow a term from mechanics where relations sometimes are the opposites than of computer science? I'm aware that an algorithm is considered a "mechanical solution" but is this really the case in fact when a lot of algorithm don't have mechanical representations for instance a file-sharing network that gets quicker and faster as the usage grows, that would be the reverse of a mechanical structure that would go slower when usage grows.

• Fixed Sized Buffer or Variable Buffers with C# Sockets

  - by Keagan Ladds

  I am busy designing a TCP Server class in C# that has events and allows the user of the class to define packets that the server can send a receive by registering a class that is derived from my "GenericPacket" class. My TCPListener uses Async methods such as .BeginReceive(..); My issue is that because I am using the .BeginReceive(); I need to specify a buffer size when I call the function. This means I cant read the whole packet if one of my defined packets is too big. I have thought of creating a fixed sized Header that gets read using .BeginRead(); and the read the rest using Stream.Read(); but this will lead to the whole server having to wait for this operation to complete. I would like to know if anyone has come across this before and I would appreciate any suggestions.

• MAAS fails to Commission nodes

  - by user3644848

  I'm evaluating MaaS/Juju. I followed instructions in this link http://maas.ubuntu.com/docs1.5/install.html to setup MaaS. I'm running this in Oracle VirtualBox environment so Power options are not configured for the VMs. PXE booting VM works fine. The node shuts down itself and registers with MaaS in Declared state. Issues: a) When I Commission the VM (which is in the Declared state), first it gets IP-Config: no response after 60 secs - giving up errors. (See link below for a screenshot). b) Fails to mount the boot device and drops into initramfs prompt. I've copied logs here: https://www.dropbox.com/sh/5gy9nnonbnccufo/AAD9o4awSOtyaCCmRe5q7rBva Any help to get past this is greatly appreciated. Thanks!

• How to perform efficient 2D picking in HTML5?

  - by jSepia

  I'm currently using an R-Tree for both picking and collision testing. Each entity on screen has a bounding box for collisions and a separate one for picking. Since entities may change position very frequently, both trees must be updated/reordered once per frame. While this is very efficient for collisions, because the tree is used in hundreds of collision queries every frame, I'm finding it too costly for picking, because it only gets queried when the user clicks, thus leading to a lot of wasted tree updates. What would be a more efficient way to implement picking without as much overhead?

• Searching for a Calendar Application That Meets the Following Criteria

  - by Navarr

  My Step Father is starting his own company, and he gets the wonderful life of having to deal with multiple clients. He needs a calendar system that can do the following: Can be updated from iCal (I'm pretty sure this just means CalDAV support) Needs to be able to show different clients the details of whats on his calendar for them, while showing other client's arranged times as only busy Wants to show it in a professional way, preferably on his own website. I was looking at Google Calendar, but alas it doesn't seem to actually support it like I thought it would. He was looking at MobileMe, but its simply public. Is there a calendar app or PHP application that can be installed on his server that can do this?

• Web Host for Small Rails-based CMS site [closed]

  - by clem

  Possible Duplicate: How to find web hosting that meets my requirements? I am building a site for someone that uses a Rails-based content management system that I built myself. All of the Rails deployment experience I have so far has been over small intranets. I'm looking at web hosts like rackspace, because it seems like they're well-suited for Rails deployment. However, for a site that's not going to have more than a couple of hundred hits a month (if even that), I'm not sure it's necessary. I've also used Dreamhost's Phusion Passenger deployment for small projects before, but it seems barely functional and not well-supported, and I've also used Heroku for deployment, but I think a regular web host may do a little bit better, as they'll need things like Google Apps for Gmail set up. If anyone could provide some guidance on this, I'd greatly appreciate it. I get confused when I see things on rackspace like "1.5c/hour", because I'm not sure how that gets computed.

• Is there now any way to convert mp3 files to m4a or aac 192kbit?

  - by piedro

  Since about two years now I am trying to find a way to convert high quality mp3 files to m4a or aac files with a fixed bitrate 192k. Please don't suggest using another format - i thought this through as far as it goes. The problem here is: ffmpeg obvioulsy can't convert to a higher bitrate than 152k. Even when it says it does so the resulting files still have 152k instead of 192k. ffmpeg also has/had a bug not writing the bitrate into the audio file tags which means when testing you have to calculate the bitrate manually by dividing the filesize by the length of the audio in seconds (resulting in 152k - see above) choosing faac as converter gets me the same results other programs don't work reliably (see this thread Howto convert audio files to *.m4a? I know that this is not an original new problem but I am wondering if there is still no way to convert with ubuntu/kubuntu 12.04 after a lot time passed and I can't find some of the bug issues mentioned in the other thread anymore. So: Is there a solution after all?

• Game has noticeable frame drops but when through a profiler it always runs smooth

  - by felipedrl

  I'm trying to optimize my PC game but I can find the bottleneck since every time I run it through a profiler (gDEBugger) it runs smooths. When running outside gDEBugger I get these annoying hiccups. It's not just the graphics, the sound also gets choppy. The drops are inconsistent across runs, i.e, sometimes I run the same scenario and get no drops at all, sometimes I get a few drops, and others the game is consistently slow. The only constant is: when running through gDEBugger I ALWAYS get a smooth run. I'm suspecting something outside my game is interfering and causing these drops, but what in the hell does gDEBugger do that nullifies these drops? A higher process priority? Any ideas? Thanks in advance.

• Cleaning a dataset of song data - what sort of problem is this?

  - by Rob Lourens

  I have a set of data about songs. Each entry is a line of text which includes the artist name, song title, and some extra text. Some entries are only "extra text". My goal is to resolve as many of these as possible to songs on Spotify using their web API. My strategy so far has been to search for the entry via the API - if there are no results, apply a transformation such as "remove all text between ( )" and search again. I have a list of heuristics and I've had reasonable success with this but as the code gets more and more convoluted I keep thinking there must be a more generic and consistent way. I don't know where to look - any suggestions for what to try, topics to study, buzzwords to google?

• Xubuntu Mail Watcher (XFCE Plugin) Won't Connect To IMAP

  - by Xophmeister

  I am trying to get the XFCE Mail Watcher panel plugin to check my IMAP mail, but it won't connect to my server. I have entered the details correctly -- they're exactly the same as those I use in Thunderbird -- but nothing! When I go to select the "New mail folders..." it returns with "Failed to get folder list". If I change my username from name@domain to name, I still get this error, but it takes a few seconds longer to appear. Nothing shows up in the log. If it makes a difference, my mail is hosted by Microsoft, in some way. Like I say, I can access it through Thurderbird using the IMAP credentials; but I have the Exchange 2010 web app, if I use webmail. Could this be the problem? (Thunderbird often complains with "Command Error. 12" with what it gets back from the server, but carries on regardless.)

• Why does Live-USB boot freeze at the moving dots?

  - by Caleb

  I am currently trying to boot into Ubuntu 12.04 x86 using a USB. I used Untetbootin to do all that boot crap and what not. But for some reason Ubuntu wont load pass that screen with the dots and the purple background. What happens is the dots all light up once, then they go back to white then they all light up at the same time and then it just gets stuck there. Ive even tried using an x64 copy (since my CPU supports it) but have no luck with that either. Ive even tried different DISTRIBUTIONS of Linux and all have failed with loading. Please help
