• VS2010 changes your ASP.NET Version on setup projects to 4 - regardless

  - by blomqvist

  When converting your projects to VS2010 you get the question to migrate them to .net4. But even if you do not do that VS set the ASP.NET version to 4 for setup projects. And then when you try to install your application on a machine that does not have .NET 4 installed you will get the error message: “Could not open key: Software\Microsoft\ASP.NET\4.0.30128.0. Verify that you have sufficient access to that key, or contact your support personnel” What you need to do is to change the ASP.NET version back to 2.0 if that is what you want to use. You do that in the properties of the setup project.

• How to install kghostview

  - by feelfree

  In order to use kghostview, I download the page from here. After that, I run the following command: sudo dpkg -i kghostview_3.5.10-0ubuntu1~hardy1.1_i386.deb However, I have the following error messages: dpkg: dependency problems prevent configuration of kghostview: kghostview depends on gs; however: Package gs is not installed. kghostview depends on kdelibs4c2a (>= 4:3.5.8-1); however: Package kdelibs4c2a is not installed. kghostview depends on libqt3-mt (>= 3:3.3.8-b); however: Package libqt3-mt is not installed. dpkg: error processing kghostview (--install): dependency problems - leaving unconfigured It seems that I should also install some external packages such as gs, kdelibs4c2a and libqt3-mt. However, I do not have any idea of how to install them. I try the sudo apt-get install command, but fail. Any idea will be appreciated.

• Disabling eth0 Module on a Macbook Aluminum

  - by user115488

  The Ubuntu page for my device states the following at the bottom (Known Issues) PowerTOP reports that the module for the 10/100/1000 interface wakes the processor 100+x/sec, accounting for 50% of wakeups on an idle system. This dramatically shortens battery life. One potential solution is to unload this module if you only use wireless. I only use wireless, but I could not find instructions to "unload the module". I have a feeling if I try something related to this, but not the same, battery life will not improve and my eth0 won't work. Anyone have a good guide on this?

• Chinese bots in my forum

  - by TdotThomas

  I have a small community forum that doesn't really get posts or any real traffic. The only thing that happens on the regular is bots with Chinese IPs signing up gibberish usernames. Most bots don't make it past the captcha but some do. I try to stay on top of this by banning IPs and ranges of IPs but it doesn't really seem to help. The bots never post anything so what are they doing? Should I be worried? Should I keep banning IPs or is it futile?

• How to properly shield a PO from outside?

  - by xsAce

  Update: We are a very small team (3 people) and thus I (SM) and the PO are also developers doing some coding. We are aware of this situation and we are actively trying to recruit some new talents. But it's hard! Meanwhile... we need to adapt... so my question: The PO complains about having too much outside noise (mainly stakeholders feature requests), and he can't focus on the sprint realisation. We agree that we should try to educate people on our process implications (sprint durations and product backlog), to reduce the noise. But as a ScrumMaster, how am I supposed to shield a PO from outside? Isn't he supposed to be in contact with the management and business? Also, if people outside don't want to waste too much time learning agile, what is the best way to educate them?

• External hard drive failing, is backup recovery possible?

  - by backitup

  I have a Seagate Freeagent external hard drive. While I was backing it up on Windows XP my pc crashed and I received the horrifying "Delayed Write Error" when I rebooted citing "$MFT" and a few other files. I tried to unmount it, but to no avail. Now my pc just crashes when I try to access it via Windows. In Ubuntu I am able to view it through disk utility. SMART status is "DISK FAILURE IMMINENT". Fdisk doesn't work, and the SMART tests fail on "Reallocated Sector Count". Is there any way for me to rescue any of my data. I can still access the drive but as soon as I do that it crashes.

• Menus don't sync in the first place

  - by Bruce Mincks

  I have been wrestling with prompts about my default key ring for months, finally made contact with Ubuntu with the right password, and find that when I try to sync evolution Ubuntu directs me to "system-preferences- " and then the road forks between the "passwords and encryption" you indicate and the "encryption and keyrings. I have no idea which version I am using, at this point. The road goes downhill from there. I would really like to synch my windows manager and Inkscape vs. ImageMagick display (circles display as semicircles). Can someone set me straight?

• Ubuntu One doesn't show captcha in windows 7

  - by Fredrik Hansson

  I try to set up a new U1 account in W7. However, the sign on screen reports "There was a problem getting the captcha, reloading" - but nothing seems to happen. I tried it on two different computers (in the same home network). Same result. Anything to do or is U1 for W7 corrupt? Also experiencing this problem. Trying to install latest U1 on brand new Toshiba Win7 laptops at work and the captcha field is simply blank, there is nothing to copy. Tried refresh, restart, reload and different browsers (Firefox 13, IE9) and nothing improved the situtation. Without being able to see the captcha I cannot do anything at all and will have to use silverlight if I can't overcome this.

• Why can't I access hw:1,0 until gstreamer-properties is run once?

  - by Shadd

  Not necessarily an Ubuntu-specific question but I wasn't sure where else to ask. I have an AverMedia DVD EZMaker 7 which plugs into USB and works well on Ubuntu 12.04. I downloaded and installed the official drivers without error. However, when I try: gst-launch alsasrc device="hw:1,0" ! alsasink device="hw:0,0" it tells me: Setting pipeline to PAUSED ... Pipeline is live and does not need PREROLL ... Setting pipeline to PLAYING ... New clock: GstAudioSrcClock which is the normal output, however there is no audible sound. Trying the command again doesn't help. If I run gstreamer-properties and close it right away (don't need to touch any controls), THEN the gst-launch command works. If I unplug the device and plug it back in or restart the computer, I have to run gstreamer-properties again. What is gstreamer-properties doing that enables the audio?

• Beginner help: where to begin [closed]

  - by shad

  I want to learn how to program. A main stream programming language such as Java, C++/C# is my primary target. Currently, I am a high school student planning to take programming, Digital electronics courses next semester. My biggest problem is that I do not know where to start and I have no one to consult with. Should I take a course at my local community college this summer? Get some books or try learning from some internet websites? What would be the best option a book or website? note that this is no longer my words, but rather ChrisF's because he decided to reword the question a bit (bad) and spaced it out better (good).

• 1080p on TV not working

  - by and471

  I am trying to connect my laptop (Samsung Series 5 Ultrabook) to my TV (Toshiba WLT66/67 Series) and get it to output to the TV at 1080i (so basically 1920x1080) through HDMI The issue I have is that in 'Displays' the highest resolution that it gives the monitor is 1280x768, however I know that the TV can output at 1920x1080 at 30Hz as when I use Windows 7 it allows me to do this. I looked around and found that I could use xrandr to try and get his resolution, however when I do: cvt 1920 1080 30 # 1920x1080 29.95 Hz (CVT) hsync: 33.01 kHz; pclk: 79.75 MHz Modeline "1920x1080_30.00" 79.75 1920 1976 2168 2416 1080 1083 1088 1102 -hsync +vsync xrandr --newmode "1920x1080_30.00" 79.75 1920 1976 2168 2416 1080 1083 1088 1102 -hsync +vsync xrandr --addmode HDMI1 1920x1080_30.00 xrandr --output HDMI1 --mode 1920x1080_30.00 My TV screen just remains blank :( Any help? (if you need any more information please ask)

• eth0 not working on startup

  - by user4106

  Hi to all, This might sound strange but, working with my Lubuntu 10.04 i've experienced troubles when connecting to my eth0 newtwork. After some googling, i've found out that by writting in the CLI the following command: mii-tool eth0 -F 10baseT-FD and activating the eth0 in the toolbar (by clicking "activate eth0") everything works just fine. Well, up to now, i did not have any problem, because every time i turned on the computer i had to do this, but it was very little effort.But now, i would like to use the machine as a file server, accesing it by ssh, without monitor or keyboard. So, i won't be able to make this actions, and can't do this at startup because mii-tool needs root permissions. So, the question is: Do you know what does that command do, and how can id make that change permanent? Or do you know any other solution for my problem? I hope i was clear! If not, tell me and i'll try to be as clearer as possible. Thanks in advance!

• Scalability of multi-threading in game server

  - by Taylor Hill

  What is a reasonable number of threads for a simple 2D mmo in Java? Is it reasonable to have two threads per connection, one for the input stream and one for the output stream? The reason I ask is because I use a blocking method on the input stream, and a workaround seems unnecessarily complex if I were to try to get around it without adding threads. This is mostly for my own edification; I don't expect to have 5 million people playing it ever, or even 5, but I'm wondering what a good scalable solution is, and if this is reasonable for a small server (<30 connections).

• Any chance for fully working X1600 PCI-E ID 71c3/Unity under Ubuntu 12.04?

  - by user74975

  How can I get Unity working under an ATI Radeon X1600 PCI-E on Ubuntu 12.04? I'm rather Windows guy, but I can do some things with CLI. ATI seems to have ended support for this card for both Windows and Linux. Theres no proper driver in jockey; binary driver from Software Center doesn't give Unity, just Unity 2D. Yes, I've tried the commands from this post - without any positive results; should I try installing drivers manually?

• My boss decided to add a "person to blame" field to every bug report. How can I convince him that it's a bad idea?

  - by MK_Dev

  In one of the latest "WTF" moves, my boss decided that adding a "Person To Blame" field to our bug tracking template will increase accountability (although we already have a way of tying bugs to features/stories). My arguments that this will decrease morale, increase finger-pointing and would not account for missing/misunderstood features reported as bug have gone unheard. What are some other strong arguments against this practice that I can use? Is there any writing on this topic that I can share with the team and the boss? I find this sort of culture unacceptable to work in but want to try and change it before jumping ship. Any input is appreciated.

• Instantiating Interfaces in C#?

  - by RealityDysfunction

  I am reading/learning about interfaces in C# at the moment, and thus far I managed to understand how it differs from an abstract class. In the book I am reading the author explains that interfaces are the ultimate abstract class and that it simply sets the standard of certain methods the inheriting class will have, but then provides the following example... static void Main(string[] args) { ... Circle c = new Circle("Lisa"); IPointy itPt = null; try { itPt = (IPointy)c; Console.WriteLine.(itPt.Points); } catch (InvalidCastException e) { Console.WriteLine(e.Message); } ... } The line that absolutely throws me off is the "IPointy itfPt=null;" did he just declare an interface??? I thought interfaces are abstract and can only be inherited? What kind of sorcery is going on here? Thanks for any help, I

• Creating a interactive grid for puzzle game

  - by Noupoi

  I am trying to make a slitherlink game, and am not too sure how to approach creating the game, more specifically the grid structure on which the puzzle will be played on. This is what a empty and completed slitherlink grid would look like. The numbers in the squares are sort of clues and the areas between the dots need to be clickable. http://i.stack.imgur.com/U1kXn.gif http://i.stack.imgur.com/RMwiv.gif I would like to create the game in VB .NET. What data structures should I try to use, and would it be beneficial using any frameworks such as XNA?

• Issues with external mounting after pysdm removed

  - by K. R. Huard

  So, I'm very new to ubuntu. I was having troubles getting my external hard drive to be read/write permission. It's owner is my macbook, and writing on the drive was repeatedly denied. In trying to sort this out, I tried the Nautilus commands (no success), installed the PYSDM application, changed some things (as suggested by this user in this forum http://askubuntu.com/a/113992 )but then found that I was getting an error message whenever I tried to mount an external storage device. The error is: Unable to mount DERPSTICK error mounting: mount exited with exit code 1: helper failed with: [mntent]: line 14 in etc/fstab is bad mount: only root can mount /dev/sdc1/ on /media/sdc1 Others with similar problems put their fstab up here, but I'm not sure how to bring it up, or if I should even try. Thanks for your time!
