• Desktop interface crashes after software updates

  - by N.C. Weber

  Recently, after installing Ubuntu software updates on the evening of December 7th, 2012, my desktop interface crashes regularly leaving me with a command line screen with a long string of automated commands showing (I assume what goes on behind the pretty desktop). At first, I thought it was only crashing whenever I played DirectX games in WINE, but now it crashes if I open the native Firefox browser or if it's doing nothing at all but sitting there. Apport attempts to report the bugs after restart, but often they crash as well. I've done a SMART check on the hard drive, and everything report OK. No read errors, no bad sectors. I am using an Acer Extensa 4620Z Memory: 2.0 GiB Processor: Intel Pentium Dual CPU T2370 @ 1.73GHz x 2 GraphicsL: Intel 965GM x86/MMX/SSE2 OS: Ubuntu 12.10 32-bit Disk: 116.0 GB with 33.4 GB Available

• Ubuntu 12.04, web cam light flashing

  - by user205877

  Have been running Ubuntu on my Compaq C757 reliably since 9.10. Currently running a fresh install of 12.04 LTS. Somewhere during my regular updates, my webcam started flashing its power light. Light flashes from logon screen all throughout my session. I am not running Google Chrome but chromium and firefox. Webcam works normally whenever I run Cheese webcam booth, light comes on solid and webcam works normally. I close out of Cheese, webcam shuts off, and then the light starts blinking again. My system is dual boot, when I boot into Windows 7, webcam does not exhibit this problem. I suspect issue may be related to new laptop power management settings in kernel based on research on the web of similar problems, but I do not know how to instruct it to treat webcam differently.

• Why is this by passing the SUDO password?

  - by John Isaacks

  I have a bash script I am using to automate a SVN checkout. The contents of the file were: #!/bin/bash cd /var/www-cake sudo svn checkout file:///usr/local/svn/bash_repo/repo/ Then when I double click the file it would ask me what to do, I would click the button "Run In Terminal" and then a terminal would pop up and ask me for the SUDO password. I would enter it, the script would execute and the terminal would close. I wanted to give some sort of indication that the script ran successfully so I edited my file to look like: #!/bin/bash cd /var/www-cake sudo svn checkout file:///usr/local/svn/bash_repo/repo/ echo "Head revision has been pushed to live server" I expected the terminal to now stay open and tell me the message afterwards. To my surprise it now opens and immediately closes. The script does execute and I no longer have to put in the SUDO password. Is this right? I do not understand why this is happening, seems like a security issue.

• Scrum - how to carry over a partially complete User Story to the next Sprint without skewing the backlog

  - by Nick

  We're using Scrum and occasionally find that we can't quite finish a User Story in the sprint in which it was planned. In true Scrum style, we ship the software anyway and consider including the User Story in the next sprint during the next Sprint Planning session. Given that the User Story we are carrying over is partially complete, how do we estimate for it correctly in the next Sprint Planning session? We have considered: a) Adjusting the number of Story Points down to reflect just the work which remains to complete the User Story. Unfortunately this will mess up reporting the Product Backlog. b) Close the partially-completed User Story and raise a new one to implement the remainder of that feature, which will have fewer Story Points. This will affect our ability to retrospectively see what we didn't complete in that sprint and seems a bit time consuming. c) Not bother with either a or b and continue to guess during Sprint Planning saying things like "Well that User Story may be X story points, but I know it's 95% finished so I'm sure we can fit it in."

• Using RegEx's in Multi-Channel Funnels in Google Analytics

  - by Rob H

  For some reason, I can't get my multi-channel funnel which utilizes RegEx's in the path steps to function -- it keeps coming back with no data. There are a few variables which may be holding things up, but I can't figure out the origin of the problem, nor a solution. Here's the situation: The funnel is tracking conversions, defined as when a user completes 4 steps to signup Steps are not "required" Default URL is set to https://example.com There is a 302 redirect set up on our site that leads from http://example.com to https://example.com Within the funnel, steps switch from non-secure pages (unless browser is set to secure browsing), to secure pages once the user moves from the landing page to the second page of the sign-up process (account placeholder has been created) URL at that point contains the variable of publisher number within (but not at the end) the URL My RegEx's are all properly written as tested on rubular.com

• Windows 8 keyboard shortcuts when virtualising OS X

  - by mbrit

  Seriously, I have no idea why this took me so long to actually sort out.So in Windows 8 you have new keyboard shortcuts for accessing search (Win+Q), charms (Win+C), settings (Win+I), etc. Problem is that some of those collide with standard OS X mapping - for example Win+Q will close down VMware, Win+C will issue copy, etc.You can add additional mappings into VMware. Use the Preferences panel to do that. Here you can see that I've mapped Win+Shift+C to Win+C. (OK, that assumes you use a Windows keyboard with a Mac, like I do. If you use a Mac keyboard, you're mapping Apple+Shift+C to Win+C.)

• What's the best way to version CSS and JS URLs?

  - by David Eyk

  As per Yahoo's much-ballyhooed Best Practices for Speeding Up Your Site, we serve up static content from a CDN using far-future cache expiration headers. Of course, we need to occasionally update these "static" files, so we currently add an infix version as part of the filename (based on the SHA1 sum of the file contents). Thus: styles.min.css Becomes: styles.min.abcd1234.css However, managing the versioned files can become tedious, and I was wondering if a GET argument notation might be cleaner and better: styles.min.css?v=abcd1234 Which do you use, and why? Are there browser- or proxy/cache-related considerations that I should consider?

• How to update dependency during runtime in my .NET application?

  - by Louis Rhys

  I have a server-client application. Sometimes the server is updated which requires some DLLs in the client to be updated as well (The DLLs are the dependencies of the main executable). For now, we have to close the client, manually deploy the DLLs, and then start the client again. This is kind of an inconvenience because the client is an automated application, so normally it doesn't need any user intervention. Is it possible for this to be done automatically without restart or user intervention? Like, the client would download the latest DLL, and replace the current one?

• Are the National Computer Science Academy certifications worth it?

  - by Horacio Nuñez

  Hi to every one. I have a question regarding the real value of having NCSA's certifications. Today I reach their site and I easily passed the JavaScript certification within minutes, but I never reach questions related to Literal Javascript Notation (Json), closures or browser specific apis. This facts let me to doubt a bit of the real value of the test (and the proper certification you can have if you pay them $34), but maybe Im wrong and just earned a respected certification within the States for easy questions... in wich case I can spend some time doing other certifications on the same site. Did you have an NCSA certification and think is worth having it in your resume, or you know of a better certification program? thanks in advance, and looking forward to see your considerations.

• Website inheritance of ownership question

  - by Adrian Denham

  I paid for a web site for my motel business, then due to my landlord actions I was placed in a position to file for bankrupcy. I asked my IT manager and web developer to close down the web site for the business. He has since then sold my web site to the new owners. I took all the photos myself and I am in at least 4 of the photos on the site. There are no changes to the site as I left it and it now states that it is under the copyright on the new owners? I am not sure what I should do as this happen 10 months ago and I have just found this out. Thank you for your help, I am in Australia.

• VPS Server OS differences

  - by silvercover

  I have two VPS servers. one of them is running Linux and the other is Windows one. I've uploaded same file to their public_html folders and could see them in my browser via static IP address of each one like http://178.63.165.178/getorder/file.xml and http://178.63.165.178/getorder/file.xml. On the other side there is a device called SMSPrinter that configured to read those XML files using GPRS and need static IP address to reach destination server. unfortunately this device can only read file from windows server and could not reach the file on Linux server. There is no note in this device manual suggesting Windows server or specific OS! I've also set file permission on Linux server to 777 to have no limitation. what could be the cause of our problem? Thanks.

• Webapps don't open correctly when using Chromium

  - by Alex

  I have just installed Ubuntu 12.10 completely fresh, the old version of Ubuntu was discarded or overwritten (or whatever you call it). I want to use the Ubuntu webapps with Chromium but I've had several problems. }The first problem is that Chromium won't ask me if I want to install a webapp if I go to a supported site (and I don't already have the webapp installed). The second problem is that when I install the webapp by visiting the site in Firefox, and then I try to open it in Chromium, Ubuntu will open a completely new Chromium icon and window in the Launcher, and the icon will be labeled "Untitled"; also there is no search bar in the new window, only the tab at the top. I've tried using several webapps with Firefox set as the default browser and they work as expected: once the webapp icon is clicked a Firefox window is opened on the Firefox launcher icon, and the window has 'new tab' button and search bar.

• Why does Google Analytics show false referrals?

  - by Peter Merrill

  Ever since Google revamped their Analytics interface I've been noticing a weird "bug" while viewing the "Real-Time" overview area. From this area I can obviously see live stats of visitors to my website but when I visit my website by opening a new tab (Chrome) and manually visit website the real time stats sometimes look like the image linked below. http://i.stack.imgur.com/mfniY.png Is there any reason why Google is saying that I was referred by Stack Overflow when I'm visiting my website from a new tab? Could this be something do to with how I installed the analytics on my site or could this be an issue with browser cookies? Have anyone else noticed this? I am mainly concerned about this because in the standard reporting area of my Analytics panel my referral stats are getting thrown off every time I visit my own website.

• What is the replacement for the Web Intents HTML standard?

  - by Tom

  "Web Intents" were deprecated in Chrome 24 (November/2011) and are no longer supported in any browser: We also gathered a lot of valuable data and feedback from our experimental support for Web Intents and decided to disable the feature in today's Beta release. Is there an HTML5 standard that I can look into as an alternative to what Web Intents intended? I'm interested in how web services can be stitched together. For example, imagine a website that can import a image from any number of web-services, modify the image in some way, then push the file back to any number of other web-services, all via HTML5 standards.

• How to mimic the same fixed-size horizon as in this racing game?

  - by Aybe

  I am trying to replicate the same horizon (buildings and sky) as in the image below: As you can see, the player has advanced in a straight line, yet the horizon has still the same size: This is my attempt using 3D, while it's okay when the player is on the start line: It's not so great when the player advanced as much as in the image no. 2: This is an overview of where the horizon buildings and sky are located: Obviously this won't achieve such effect when one is close to it, so I've tried to scale up the horizon on all axes but the problem is that the buildings are too small depending where you look at them from. How can one mimic such rendering ?

• 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.

The package and it's dependencies all installed fine and I log in using a web browser, however I'd like to add hosts now and according to the official Nagios Documentation the config file should be in the /usr/local/nagios/* directory.

I'm running Xubuntu 12.04 64-bit Any help at all would be greatly appreciated, Thank you!

• HTML5-Canvas: worth using ImpactJS or other framework?

  - by John

  I've been making an HTML5 game without any type of external framework. I haven't found a reason to use one so far. However, there is one thing I'm wondering about. On my Galaxy Nexus, I get about ~40fps. While that would usually be a decent framerate, my game is a rather fast paced game with a gamepad. Because of this, it feels very unsatisfying to play when not capped at 60fps. Are there frameworks out there that can improve performance without toning down on graphics? Or is there something I could do myself without necessarily having to use a framework? I've looked over the basic things such as sticking to integer coordinates, but I didn't see an increase in performance whatsoever? I did some testing with jsperf and results were virtually identical. Does this depend more on the browser?

• After changing web host, I get a 'file does not exist' error

  - by Jordan

  I run a WordPress blog, and have recently changed web hosts. When changing web hosts, I copied all files and exported/imported the database etc as explained by lots of tutorials found easily on Google. The blog home page works fine. What goes wrong: When I click on any link from the home page, the browser gets stuck in a redirect loop. Looking at the error log, I see: File does not exist: /usr/local/apache/htdocs/index.php The directory /usr doesn't even exist for my website - so perhaps this is looking for a file that was present using my old Web Host and is no longer present with my new web host? What is going on, and how might I resolve it?

• 13.10 Unable to link Google account

  - by Lolwhites

  When I try to connect my Google account, the following happens: I open "Online Accounts" - the Google account appears in the left hand margin. When I highlight it, I am invited to grant access. On clicking on "Grant Access", I get a window with the following message: Erreur :invalid_request Invalid response_type: code&access_type=offline En savoir plus Détails de la requête response_type=code&access_type=offline scope=https://docs.google.com/feeds/ https://www.googleapis.com/auth/googletalk https://www.googleapis.com/auth/userinfo.email https://www.googleapis.com/auth/userinfo.profile https://picasaweb.google.com/data/ redirect_uri=https://wiki.ubuntu.com/ client_id=759250720802-4sii0me9963n9fdqdmi7cepn6ub8luoh.apps.googleusercontent.com type=web_server Clicking the "Cancel" button returns me to Online Accounts, but a new window opens with the same error messages, and pops up repeatedly when I try to close it. I have tried to remove the account and re-add, but when I click on "Remove Account" I am asked if I'm sure, but nothing happens when I click "Remove"; the dialogue box disappears but the account stays. There's a bug report on Launchpad here but it says the bug has been fixed. Not for me, apparently...
