• Microsoft Azure Outage

  The beginning of Azure's troubles was documented last Wednesday at approximately 1:45 a.m. GMT when its service management component malfunctioned. The initial message on the outage, posted by Microsoft on its Azure service dashboard, read: We are experiencing an issue with Windows Azure service management. Customers will not be able to carry out service management operations. Microsoft continued with its updates at 5 a.m. GMT, when it assured users that fewer than 3.8 percent of hosted services had been affected by the outage. The company also said it was doing its best to stop the issue ...

• Color distortion with Intel HD4000 over HDMI output - VGA is fine

  - by Simon Möller

  I set up a new system with i5 3570k gigabyte z77 d3h using integrated graphics (HD4000) and I've installed the 64bit Desktop version of 12.04. Connected to my Acer Screen via HDMI, the colors are horribly distorted. I think the biggest issue is that black appears as greenish. Over VGA everything is fine. Interestingly, I once observed that connecting both, the VGA and the HDMI cable at the same time, solved the issue. Ubuntu thought 2 screens were connected, I mirrored the image, and over HDMI the colors looked fine. However, after a reboot I am now unable to reproduce this behavior. I read frequently, that Intel hardware should be supported out of the box by Ubuntu but it doesn't seem to be the case here. Should I upgrade my Kernel? If so, which version would you recommend? Thank you for your answers!

• Theme sometimes fails to load on some UI elements

  - by Neil

  I have no idea if this error as been seen before or not, I have looked around and found people saying they have errors that sound the same but none of the fixes work, my issue is that sometimes the theme does not load some parts of the UI, (the buttons and icons in this case) but the rest is just fine (window bars e.t.c) so I have no idea what the issue is, it works just fine for the most part but sometimes has this bug, if you restart the system it tends to fix it for some time so its hard to see how it could be a graphic card error, however I am very new to linux systems so I may be missing someting very fundamental here. Thank-you in advance. This image shows my problem

• Still no wireless after b43 with Dell Inspiron 1525 (Ubuntu 12.04)

  - by DanielleN

  So I followed the instructions here http://ubuntuforums.org/showthread.php?t=1974006 about how to solve this issue. It worked for a bit and then stopped. After doing a modprobe I could at least see my network and click on it but it would not connect (I can always see it if I look under the listed wireless networks under VPN Connections, however). I'm thinking, from what I read at least, the issue might be that my wireless switch was on during those first steps. Do I now have to undo the b43 install and do it again? Or is there something else I could try? I just made the switch to Linux yesterday, so I am hesitant at this point to mess with anything on my own. I should note now that it was installed by someone who knows what they are doing, so we are all good on that front.

• Blender: Having trouble moving vertices

  - by capcom

  I've been using Blender for two days now, and ran into an issue while following a tutorial. Before anything else, I'd like to show you all what my problem precisely is. Here is a short video I uploaded: click here. I thought it may be easier for you all to help me identify and solve my problem more accurately with a visual aid. I would like to emphasize that this issue began to occur after I extruded that trapezoidal region (misstated as a parallelogram in the video). I decided that I did not want the extruded region, and just hit undo. Ever since then, I began to experience the problem you viewed. Thanks.

• IIS and content caching

  - by JayC

  I'm a web developer and administer of a Windows 2008R2 Could Instance with IIS 7. I recently made an update to our website, but when I revisited the website, the website was being viewed with old stylings. I did a refresh (shift + reload button in Firefox) and of course the website displayed as it should. I didn't worry about it, until my client had the same issue in Safari. So, my question, in general, is, how do I prevent this from happening again, and yet still afford some caching of our site? I noticed we did not have content expiration set up on our webserver sites, so I've set that up, but did I really need to? I've also looked at Etags, and, honestly, it's hard for me to know whether or not I should use them or not. One comment I read somewhere there isn't really any issue with Etags scenarios in IIS (even in webfarms)... but, I dunno. Anybody have any suggestions, links, info? Thanks.

• Distributed cache and improvement

  - by philipl

  Have this question from interview: Web Service function given x static HashMap map (singleton created) if (!map.containsKey(x)) { perform some function to retrieve result y map.put(x, y); } return y; The interviewer asked general question such as what is wrong with this distributed cache implementation. Then asked how to improve on it, due to distributed servers will have different cached key pairs in the map. There are simple mistakes to be pointed out about synchronization and key object, but what really startled me was that this guy thinks that moving to database implementation solves the problem that different servers will have different map content, i.e., the situation when value x is not on server A but on server B, therefore redundant data has to be retrieved in server A. Does his thinking make any sense? (As I understand this is the basic cons for distributed cache against database model, seems he does not understand it at all) What is the typical solution for the cache growth issue (weak reference?) and sync issue (do not know which server has the key already cached - use load balancing)? Thanks

• Wifi very slow on Ubuntu 12.04 but not on Win7, need help

  - by user84504

  I have an enormous problem: I've a Sony Vaio VGN-NR21S with win7 and Ubuntu 12.04 in dual boot. With Windows everything is fine (except that is windows) but with Ubuntu the wireless connection is awfully slow, basically unusable. I've already search for similar discussion but the solution proposed didn't worked. I've noticed this issue also in live mode both with ubuntu and linux mint. I've installed Ubuntu onto an Acer that shows the same problem when connected via wifi to my router, so I think that maybe the issue is about compatibility with my home router. I really need help, I don't want unistall ubuntu! Please tell me which output u need to help me, thanks.

• Simulate 'Shock absorbtion' with tire rubber in PhysX (2.8.x)

  - by Mungoid

  This is a kinda tricky question and I fear there is no easy enough solution, but I figured I'd hit SE up before giving up on it and just doing what I can. A machine I am working on has no suspension or shocks or springs of any sort in the real machine, so you would think that when it drives over bumps, it would shake like crazy but because its tires (6 of them) are quite large they seem to absorb a lot of shock from the bumps. Part of this is because the machine is around 30k lbs and it just smashes/compresses any bumps in the ground down (This is another issue im still working on) and the other part is that the tires seem to have a lot of flex to them with a lot of air as well. So my current task is to simulate shock absorption in physx without visibly separating the tires from the spindle/axle.. I have been messing with all kinds of NxMaterial, NxSpring, Joints, etc. and have had no luck getting this to work. The main problem is that the spindle attached to the tire is directly in the center and the axle is basically solidly attached to the chassis, so if i give it any spring or suspension travel, that spindle on the tires will move upwards or downwards, looking very odd because now its not any longer in the center of the tire. I tried giving it a higher restitution but that just makes it bouncy without any shock absorption. Another avenue I am messing with is to actively smooth the terrain in front of the tires so that before it hits a bumpy patch, that patch is smoothed and it doesn't bounce. The only issue with this is that it is pretty expensive to do with 6 tires, high tesselation of the terrain and other complex things going on at the same time in this simulation. I am still working on this but I am hoping to mix and match a few different aspects to get the best possible outcome. This is a bit of a complex issue so I'm not expecting anyone to have a definitive answer, just hoping someone may think of something I haven't =-) -Side note: Yes i know PhysX 2.8.x is quite outdated but we have to stick with it for this implementation. We are in the process of going to another physics engine but it is out of scope to apply that engine to this project.

• Ubuntu 12.10 Sound resumes after I suspend and resume.[ACER 4830 TG]

  - by user70716

  I installed the 12.10 yesterday and like 12.04 there was no sound, I have an ACER 4830 TG. I noticed that the HDMI output is working fine , But Speaker or Headphone isnt working. So i did the following: sudo add-apt-repository ppa:ubuntu-audio-dev sudo apt-get update sudo apt-get dist-upgrade And still couldn't get the sound . Then i found the temp fix for this issue. The temp fix is to Suspend the machine completely and resume. However after restart the same thing happens. Is there a solution to this issue?

• file:///cdrom/pool/main/k/klibc/klibc-utils_1.5.25-1ubuntu2_amd64.deb was corrupt

  - by curlyreggie

  I guess this is trivial and most commonly asked question, but I'd reiterate it again here as I'm not able to find a correct solution. I'm trying to install Ubuntu Cloud setup on VMWare using the package from http://download.ubuntu.com and have this basic installation setup issue as per the below image. file:///cdrom/pool/main/k/klibc/klibc-utils_1.5.25-1ubuntu2_amd64.deb was corrupt The issue is I cannot continue by skipping this as you know this happens to be the most important setup. How can I fix this? Help is sincerely appreciated.

• Full brightness and keyboard backligh at boot

  - by joelalmeidaptg

  I own an Asus N56VZ, and each time I start Ubuntu (13.10 and prior versions) my screen brightness and keyboard backlights reset their values to the max. Ubuntu doesn't save my settings on reboot. I was wondering if someone could help me with this? It is horrible when, at night, I turn on my computer - it is like looking directly to the sun, and it hurts my eyes. I tried googling and none of the pages I found actually helped. I think my issue might be grub-related. I have a dual-boot with Windows 8.1, so before I start my computer I see grub to choose my operating system. My screen starts at full brightness as soon as I reach grub. Maybe he is making the OS forget about my last values, overriding it with its? Does someone knows how to solve this? Thanks in advance :) PS: I'm using bumblebee with Nvidia driver 304, but this issue existed before I installed it.

• How can I fix unreliable Unity startup?

  - by Vagrant232

  When I log in, either Unity loads perfectly or it just doesn't; all I see is my desktop background. Commands don't seem to work and I can't switch to the terminal view. No matter how long I wait, Unity doesn't start. I never had this issue with Oneiric Ocelot. Other GUIs such as GNOME 3.4 don’t seem to be having that issue. I've got MyUbuntu, Ubuntu Tweaks, CompizConf and other tweaking tools installed. Could they be causing the problem? If not, what should I do? I'd really like to use Unity again. Thanks in advance!

• How to teach your users/customers to send better error descriptions

  - by ckeller

  I often have to deal with customers or users which are reporting errors in applications. Most of the time their content is something useless as ERROR!!! x does not work without much more information. For resolving the issue I have to request every single detail of them, which often is more time consuming than fixing the issue itself. Other send information in formats which are not ideal, like screenshots (of data records, not of errors) although they could send a link (we have access to the systems) and so on. How do you tell your users/customers to describe the problems with more details so that the whole process could be easier for both sides? edit This question is more about the social skills, than how to achieve programmatic collection of logs and error information. I'm aware of the fact that this should be part of good software design.

• CSS not loading when site is viewed via Windows VPN

  - by Dreamling

  Internal site has recently been redesigned, but IE8 does not seem to be loading the new css rules only when viewed via VPN. I really have no clue what to look for. I can't reproduce the problem, but it's apparently affecting client for the last month. I've suggested: Reloading IE8 Checking Internet Permissions Flushing the cache I'm not really certain what direction to search for the answer. Is it likely to be a server permissions issue? a VPN connection issue? a rare ie8 CSS bug?

• My webcam stopped working, how do I fix it?

  - by Delilah

  I'm using Ubuntu 10.10 on a new Compaq Presario CQ56. The webcam was working fine for the first two days, in both Skype and Cheese, but simply turned black with thin vertical lines in the middle of a Skype call and now refuses to work in any program, including gstreamer-properties, Cheese, and VLC. It gives a black screen when rebooted into a live CD and tested. When tested, it either shows a plain black screen or black with thin vertical lines. Attached is an image of the video shown (it is static, there is no noise or static, and no response to variance in light). Also, when I play music or sounds, it makes a garbled noise related to the sound being played, which may or may not be connected to the webcam issue. If anyone has any ideas on what caused this, or whether it's a hardware or software issue, or how to fix it, I would appreciate them very much, Thanks

• Compiz ( or even compositing in general) is not starting up when I login. Solution?

  - by ender.cc

  Whenever I log into a desktop environment, it doesn't seem that compositing is starting. Unity 2D works fine, but when I go to Unity 3D Compiz doesn't start up. I have to type compiz --replace & in terminal every time I login. Another example is when I log into a Cinnamon session, theming support is suddenly gone (although this may be a separate issue). If it helps im using the latest (295.40) NVIDIA drivers. EDIT: I am having exactly the same issue in both cases, upgrading from 11.10 and with a clean installation, in 32 and 64 bits. Related post.

• My data vanished after copying to E drive

  - by pnp

  Of late I had been thinking of having a fresh install of Ubuntu. So I cut-pasted all my required files and folders in my E drive. Then I decided to not to have a fresh install and just let it be. Later, when I booted up in Windows (dual-boot with 12.04 and Windows 7), I found that the files and folders I had cut-pasted from my home account in Ubuntu are just not there. What is even more surprising is that now, when I am back on Ubuntu, those files and folders that should have been there in my E drive are also not there. Is it an Ubuntu issue or a hard drive issue?

• Ubuntu 12.04 intermittently fails to wake up from sleep

  - by stacksia

  When I put my Ubuntu 12.04 machine into sleep, sometimes on waking up, it fails, logs me out, and takes me back to login screen. When I log back in, it tells me some unexpected error happened, but it fails to let me report the bug. This has started to happen recently, but I don't know what triggered it. uname -a Linux [name] 3.2.0-30-generic #48-Ubuntu SMP Fri Aug 24 16:52:48 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux The issue seems similar to Xorg intermittently restarts after suspend. But in my case I am not sure if it is a Xorg issue. I looked at xorg logs, but didn't notice anything indicating an error. I know I am not providing a lot of info, but I am not sure where (e.g. which log files) I should seek for more info.

• laptop screen goes blank after waking from sleep

  - by Tojo Chacko

  I have been facing this issue from the last week after some update. Whenever my laptop wakes up from suspend state it just shows me a blank screen. Regardless of whatever I do(move my mouse, press keyboard buttons) it just refuses to wake up. I am forced to do a restart and lose all my unsaved files. Has this issue been reported for Ubuntu 12.04? I am using a Lenovo X200 with Intel Mobile 4 Series Graphics Chipset. Please let me know if any body has found a fix for this.

• Site returning 404 header to google, not sure why

  - by Damon

  A Drupal site that works fine for regular users returns a 404 not found error when I try to use the W3C validator on it; it is also not being indexed by google at all (which is the main issue but I suspect there is a connection). It is a https:// site with .htaccess rule to redirect any http:// request to the https://. I had had it running in google webmaster tools and thought it was fine, but it turns out I had not added the https domain. After adding the https domain it's also returning the header as HTTP/1.1 404 Not Found Date: Mon, 15 Oct 2012 19:37:43 GMT Server: Apache Expires: Sun, 19 Nov 1978 05:00:00 GMT Cache-Control: no-cache, must-revalidate, post-check=0, pre-check=0 Robots.txt just has User-agent: * Crawl-delay: 10 # Files Disallow: /cron.php How can I check what the issue is here?

• How to fix indicator icons from being cut off?

  - by Jay

  A friend of mine just upgraded from 9.10 to 10.04 and the icons for the indicator applets all appear cut off on both the bottom and the top. See picture above. Note that the icons in the old systray/notification area on my friend's panel all still display correctly, so it's a problem with indicator clearly. My question: How can this be fixed? (I have a 10.04 system that I did a fresh install on, and I don't have this issue, so I'm guessing it's an issue with upgrading. Thanks.

• 12.04 freezes on install

  - by CHris

  I'm new to ubuntu and can't for the life of me understand how to get around this issue. I'm having a problem where when I insert the boot disk that i burned for 12.04, it loads and gives me the language option and select an installation type, i select either try ubuntu / install ubuntu and it begins to load. Then after about 5 mintues of the purple screen with the dots under the UBUNTU it freezes the whole computer, and the only way to get out is to turn off the laptop with the power button. I have read previous threads saying people had similar "freezing" issues including ones that mention my model of laptop, HP Pavillion DV1000. But it appears their problems are post installation and relate to their wireless cards. I have tried changing the boot options (F6) and I am totally stuck. Can anyone shed any light on to this issue? Thanks in advance.........
