  • How do you unit test your javascript.

    - by Erin
    I spend a lot of time working in javascript of late. I have not found a way that seems to work well for testing javascript. This in the past hasn't been a problem for me since most of the websites I worked on had very little javascript in them. I now have a new website that makes extensive use of jQuery I would like to build unit tests for most of the system. My problems are this. Most of the functions make changes to the DOM in some way. Most of the functions request data from the web server as well and require a session on the service to get results back. I would like to run the test from either a command line or a test running harness rather then in a browser. Any help or articles I should be reading would be helpful.

  • Avoiding duplicate bug reports

    - by Jaakko Seppälä
    I use Linux and other open source software in my home. As I'm not a professional coder, I usually report bugs to developers as my skills are not enough to solve problems on my own. What kind of things you want me to check before I send a bug report? I mean, once I thought I found a bug in Gedit and I couldn't find similar bug in Bugzilla. But after I sent the report, some developer said that the bug is already in Bugzilla as the bug was in GTK+, not in Gedit. Sometimes it might be hard for an amateur to guess whether some previously known bug would solve the issue I found.

  • Torrent clients suddenly stopped downloading

    - by Vasilis Baltikas
    A few days ago I noticed, that Transmission in my Ubuntu 10.04 machine suddenly couldn't download anything anymore. To overcome this I have uninstalled and reinstalled Transmission and tried downloading with other clients (Deluge, Vuze) well seeded torrents (ubuntu iso images for example) without success. On the same computer I have also installed Ubuntu 10.10 and Windows 7, which I rarely use. What makes the problem I encounter weirder, is the fact that downloading via torrents works fine in my Ubuntu 10.10 and Windows partitions but not in Lucid Lynx. Browsing the web for similar problems didn't give me answers. Any help would greatly appreciated.

  • What should I worry about when changing OpenGL origin to upper left of screen?

    - by derivative
    For self education, I'm writing a 2D platformer engine in C++ using SDL / OpenGL. I initially began with pure SDL using the tutorials on sdltutorials.com and lazyfoo.net, but I'm now rendering in an OpenGL context (specifically immediate mode but I'm learning about VAOs/VBOs) and using SDL for interface, audio, etc. SDL uses a coordinate system with the origin in the upper left of the screen and the positive y-axis pointing down. It's easy to set up my orthographic projection in OpenGL to mirror this. I know that texture coordinates are a right-hand system with values from 0 to 1 -- flipping the texture vertically before rendering (well, flip the file before loading) yields textures that render correctly... which is fine if I'm drawing the entire texture, but ultimately I'll be using tilesets and can imagine problems. What should I be concerned about in terms of rendering when I do this? If anybody has any advice or they've done this themselves and can point out future pitfalls, that would be great, but really any thoughts would be appreciated.

  • Oracle Communications Calendar Server: Upgrading to Version 7 Update 3

    - by joesciallo
    It's been some time since I have posted an entry. Now, with the release of Oracle Communications Calendar Server 7 Update 3, it seems high time to jump start this blog again. To begin with, check out what's new in this release: Authenticating Against an External Directory Booking Window for Calendars Changes to the davadmin Command Enable and Disable Account Autocreation LDAP Pools New Configuration Parameters New Languages New populate-davuniqueid Utility New Schema Objects Non-active Calendar Accounts Are No Longer Searched or Fetched Remote Document Store Authentication The upgrade is a bit more complicated than normal, as you must first apply some new schema elements to your Directory Server(s). To do so, you need to get the comm_dssetup 6.4 patch, patch the comm_dssetup script, and then run the patched comm_dssetup against your Directory Server(s) instances. In addition, if you are using the nsUniqueId attribute as your deployment's unique identifier, you'll want to change that to the new davUniqueId attribute. Consult the Upgrade Procedure for details, as well as DaBrain's blog, before forging ahead with this upgrade. Additional quick links: Problems Fixed in This Release Known Issues Calendar Server Unique Identifier Changes to the davadmin command Get the Calendar Server patch Get the comm_dssetup patch

  • Mount to /dev/sdb1 without password

    - by Jarmo
    I am unable to mount a USB drive (or SD card) to my system without root access. When I plug in a USB drive, it is visible in the left column of Nautilus, but when I click on it to open it, I receive the error message Unable to mount 2.1 GB Filesystem Error mounting: mount exited with exit code 1: helper failed with: mount: only root can mount /dev/sdb1 on /media/sdb1 I am able to mount the drive using sudo mount -w /dev/sdb1, but this causes problems for operations such as creating startup discs, which requires unmounting and remounting the drive. I suspect this problem may be caused by the fact that when I upgraded from 11.10 to 12.04, I had an SD card plugged in. This caused the system to stall during later startups, as it could not find this drive. I remedied this by editing a line of /etc/fstab to read /dev/sdb1 /media/sdb1 vfat noauto 0 0 However, I am dual booting Ubuntu with Windows XP, and I have no problem mounting the C: drive of the Windows system without root access, so I feel that this is a problem related to the mount point rather than mounting in general.

  • Jquery Carousel - Need A Script Hack to Customize

    - by Leah
    I hope someone can help me out here. I am coding a site for a client using the carouFredsel. I am using this because it allows for variable widths with in the slideshow as seen here: http://2938.sandbox.i3dthemes.net/index-old.html. My problems are as follows: to use the built in auto center script the scrolling changes the white space in between images during the transition to fit the width of the wrapper. I need a hack to keep the white space during transition the same, like this: http://2938.sandbox.i3dthemes.net/index.html. Also, I can't figure out how to put this snippet into my code and make it work scroll: { onAfter: function() { if ( $(this).triggerHandler( "currentPosition" ) == 0 ) { $(this).trigger( "pause" ); } } }

  • Force Your Mac to Sort Folders on Top of Files (Windows Style)

    - by Eric Z Goodnight
    Even die-hard Mac converts have their issues with Mac OS, and one of those problems is that OS X lists folders mixed in with all other files. Here’s how to fix that in under five minutes with a clever hack. You know you’ve had that issue. You’ve dug through your files looking for that one elusive folder, and because it’s jumbled in with all the other stuff, it’s more or less impossible to find. Have no fear, with no downloads or silly plug-in software, you can finally make Mac OS behave like Windows and Linux and list those folders in the proper order.  How To Encrypt Your Cloud-Based Drive with BoxcryptorHTG Explains: Photography with Film-Based CamerasHow to Clean Your Dirty Smartphone (Without Breaking Something)

  • Has anyone got the Mist engine to work on gtk3? [closed]

    - by David
    Possible Duplicate: What GTK+ 3 engines are available? I've just upgraded my xubuntu installation to Precise and run into gtk3 theme problems - my theme based on the Mist engine doesn't work for gtk3 apps. There's a package gtk3-engines in the GNOME PPA that includes Mist, has anyone got this to work? It has a themes/Mist/gtk3.0 folder with a gtkrc file but it doesn't seem to work for me. Even if someone just has an idea where I could find more help on this I'd be grateful (is there even any documentation on making themes in gtk3?)

  • Python GUI and MVC - get variable from other module

    - by lyvic
    I am trying to split my code in different layers: GUI, reading the GUI, creating input, calculating the model, interpreting data, creating view, sending the view to the GUI. I got the idea of the MVC and would like to try to build my program that way. But I'm a little confused about how to exchange information between those modules. I'm running into problems with undefined global names and so forth. Example code how I'm trying to get out of this can be found here: http://stackoverflow.com/questions/17385373/setup-a-mvc-mvw-system-in-python-with-tkinter

  • How can I get my mysqld-swamped CPU under control?

    - by Shay Guy
    I was AFK for about 24 hours and came back to find gnome-system-monitor saying all four CPU cores on my laptop were running at full throttle. mysqld is taking up more than one full core; when I tried to end the process, it restarted with a new PID. Then there's ksoftirqd/0-3, which apparently has something to do with interrupts, but I can't tell from Google what I'm supposed to do with those four particular processes. They're taking up a quarter or more of my processor cycles. Then there's Chrome, but I can probably handle that on my own -- how do I cool down the other processes giving me problems?

  • Is it a bad practice to register sntsh.com if my name is Santosh?

    - by Santosh
    My name is Santosh but I can't register a santosh.com because it is already taken. Most extensions for Santosh are already taken. I was trying to register a domain with .sh extension but santo.sh would cost me very high and I can't afford ~$100 for just a personal domain and that's only for one year only. Now I am thinking that I should register a sntsh.com. But there is a problem, will sntsh.com over my name Santosh don't create a SEO problem? One more thing, that totally different from above topic. If I register a santosh.name domain which is not registered, won't it create copyright and any legal problems with other santosh domains?

  • What alternatives exist of how an agent can follow the path calculated by a path-finding algorithm?

    - by momboco
    What alternatives exist of how an agent can follow the path calculated by a path-finding algorithm? I've seen that the most easy form is go to one point and when the agent has reached this point, discard it and go to the next point. I think that this approach has problems when the game has physics with dynamic objects that can block the travel between point A and point B, then the agent is taken from his original trayectory and sometimes go to the last destiny point is not the most natural behavior. In the literature always I have read that the path is only a suggestion of where the agent has to go, but I don't know how this suggested path must be followed. Thanks.

  • unmet dependencies updating Intel graphics driver

  • Ripping MP3s in Rhythmbox Ubuntu 12.10 (64 bit)?

    - by James Fellows Yates
    I installed a couple of days ago Ubuntu 12.10 (64 bit). I today tried ripping a CD in the MP3 format. However, whenever I try to rip, it says it is missing an extra multimedia plugin "Gstreamer extra plug-ins (i386)". I then try to install the :i386 version of the gstreamer-ugly plugins, but then I get the same problem but with the id3-demuxer (or something similar) The Terminal output I get from both problems (but replace the "MPEG-1 Layer 3 (MP3) encoder" with the "ID3-demuxer" name) is: james@clefairy:~$ rhythmbox (rhythmbox:24122): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed Rhythmbox-Message: Missing plugin: gstreamer|0.10|rhythmbox|MPEG-1 Layer 3 (MP3) encoder|encoder-audio/mpeg, mpegversion=(int)1, layer=(int)3 /usr/lib/python2.7/dist-packages/gobject/constants.py:24: Warning: g_boxed_type_register_static: assertion `g_type_from_name (name) == 0' failed import gobject._gobject It doesn't help that each time I have to install/remove the entire Gstreamer-ugly collection each time - I can't find that specific file. The CD plays fine, it's the ripping plugin that doesn't seem to work. I didn't have this problem previously on 12.04 (64 bit).

  • Audio playback: part of song is skipped

    - by Homulvas
    I am experiencing some problems with music playback after upgrading to Ubuntu 12.10. Basically some of the songs stop playing after some time as if the song has ended. It's always the same songs and the same time. The weird thing that it happens with Clementine and Totem but VLC doesn't have this problem and it also plays as it should on Windows. I'm guessing there might be a problem with some library that's shared with by the first two applications. I don't know if it's relevant but the file format of the audio files is flac(don't know if the problem affects mp3, because I don't have many of them).

  • Windows Phone 7 Design Template

    Expression Blend is a wonderful design environment for WP7 (Windows Phone 7) but for quickly visualizing a concept nothing beats Illustrator! I am excited about WP7 and decided that having a solid .ai template would prove invaluable. Some of the details of the WP7 UI Design and Interaction Guide are a bit fuzzy (literally) but I was able to generate some useful layout guides, character styles, and symbols. While the template does not cover every aspect of the guide I think it is a good launching point; if you find it useful and extend it please share your updates (I created the template in CS4, if you have problems in earlier versions let me know).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.

  • Empathy 3.6.0 requires reauthorisation to Windows Live on every reboot

    - by Allu2
    I've been testing Ubuntu 12.10 beta2 and the only problem I've faced has been that with Windows Live Messenger(a.k.a MSN) After I have added Windows Live in the online-accounts in system settings, empathy works fine and connects to Windows Live Messenger with no problems until I reboot my system. After rebooting and logging in, when empathy connects to services it shows me message "Windows Live account requires authorisation" next to it is a button that takes me back to online-accounts where i can see the authorized Windows Live. So far the only way to get MSN work again has been to remove the Windows Live authorisation and add it again, which makes it work till the next time i close my computer. How could i make empathy to remember the authorisation to Windows Live

  • shutdown logging in ubuntu 10.04 & 11.10

    - by Joe
    When my system starts up it logs everything into syslog/dmesg. And I can review it for problems. When my system shuts down, where does that get logged? I didn't see anything obvious in /var/log in 10.04. (My 11.10 system is out of reach at the moment.) I looked at How do I turn on 'shutdown logging' or operating system tracing? but didn't see anything that helped. I use kubuntu, but all of the stuff at this level is probably the same.

  • Dimming the backlight is irreversible on a Samsung Q210 notebook, what do I do?

    - by user27304
    I'm new to the community, although I have been using Ubuntu since 2010. I have a Samsung Q210 notebook; Specs: Intel® Core™2 Duo CPU P8400 @ 2.26GHz × 2 4 Gigs RAM Nvidia 9200m GS (although system information in Ubuntu doesn't know) 194 GB HD OS: Ubuntu 11.10 Kernel is 3.0.0-12-generic-pae Although Samsung seems to be infamous for problems with Ubuntu, after upgrading to Oneiric, finally the FN Brightness Buttons are recognized. The only problem is, after dimming the backlight for a fixed amount of steps (3 or 4, I dare not count now because that would mean rebooting because I can't see anything), the display goes completely dark and using the FN buttons to brighten the backlight does not work anymore (before reaching that threshold, going brighter after dimming works). Now what do I do? File a bug report? If not, what then? If yes, how? Not sure... guess I should ask here first.. thanks for answering in advance.

  • MVC shared model different required fields on different type

    - by kurasa
    I have a model called Car and depending on what type of Car the user select the view is presented differently. For example the user selects from a grid of different cars and depending if it is a Volvo or a Kia or a Ford the view must allow different fields to be editable. For example with a Volvo the color is editable and is mandatory but with a Kia it is not. I would like to use the one Car class to bind the view but want the client side validation to pick up the required fields based on what type of car. I want to go only to one Action method for the Update what is a good way to approach this problem...? create a base class and inherit from it? will this give me binding problems..?

  • External display suddenly not detected

    - by NChase
    I have a Lenovo IdeaPad U410 running Ubuntu Desktop 13.04. I have an external monitor that I connect to via HDMI, and it's worked flawlessly for six months. I plug in my laptop, it detects the display. The "change display" key built into the laptop works for switching between the two screens. Never any problems. This afternoon, when I reconnected my computer after taking it into another room for a bit, it didn't work. When I open up Display settings, it can't detect the display. I tried disconnecting/reconnecting everything multiple times. And most strangely, that same "change display" key now behaves like a Super key, opening the dash instead of toggling the display. Nothing at all changed between when I plugged it in this morning and when it stopped working a few hours later. I tried xrandr, that doesn't detect it either. Anyone have any ideas?

  • How to recognize a good programmer?

    - by gius
    Our company is looking for new programmers. And here comes the problem - there are many developers who look really great at the interview, seem to know the technology you need and have a good job background, but after two moths of work, you find out that they are not able to work in a team, writing some code takes them very long time, and moreover, the result is not as good as it should be. So, do you use any formalized tests (are there any?)? How do you recognize a good programmer - and a good person? Are there any simple 'good' questions that might reveal the future problems? ...or is it just about your 'feeling' about the person (ie., mainly your experience), and trying him out? Edit: According to Manoj's answer, here is the question related to the coding task at the job interview.
