• Folding at home refusing connection?

  - by user49191

  I am having a slight problem. I love contributing to folding at home, if some of you dont know what it is, it's a program that downloads work from the stanford university servers, has your computer process it (takes about 12 hours for 1 assignment depending on the processor, and then uploads it back. The problem with mine is that when I run FAHControl in terminal, it says Error 111 connection refused. This doesnt happen when i run folding at home on windows. Can someone tell me how to fix this? Thanks.

• No WiFi after upgrading 12.04 kernel to 3.2.0-24-generic-pae

  - by lunar

  I'm on Ubuntu 12.04 LTS. With the previous kernel everything was okay — until today's upgrade to 3.2.0-24-generic-pae. The device network tools show that my WiFi card is in an inactive state. How can I enable it? These commands don't work: sudo ifconfig wlan0 up sudo /etc/init.d/networking restart The last one returns some weird errors, brackets, tildes, ampersands like in some kind of a loop.

• What failure can kill a long running IRC client? [closed]

  - by Xeoncross

  I have an IRC bot that I built in PHP using sockets that attempts to run forever and (if disconnected) reconnects again. I have it listening to several channels. Apparently it's fairly resilient, because it can run for several days before the process ends and CRON has to start it up again. However, based on the fact the process ends I'm assuming there are other conditions I'm not accounting for that are causing problems. I have nothing in my error logs giving me a hint. In addition, sometimes the process will continue running - but I notice it's no longer present in any of the channels on the IRC server which makes me think it violated some part of the protocol. I have logic setup to handle: reply to PING's correctly reconnect on disconnect (and reconnect to channels) respond to private messages (so someone doesn't ban it) prevent memory leaks What other failure could be killing my long-running IRC client?

• Assessing Relative Maintainability

  - by João Bragança

  We (a contractor, actually) are implementing an off the shelf system to replace a legacy homegrown system for the core domain of the company (designing widgets). Unfortunately both systems will have to run concurrently for some time, as the product just isn't ready yet. Also, the decision was made to only migrate some of the widgets from the legacy system, based on date of last sale activity. Later on a new requirement came down: certain people in the company, most of them outside of the widget development context, want to search all widgets. The search results screen has 3 pieces of data: a GUID, a human readable id that is searchable, and a brief description (may need to be searchable in the future). In the widget details, there will be multiple screens. These screens align very well along SOA / bounded context lines - a screen for marketing data, a screen for sales history, etc. UML ahead! I am probably using the wrong kind of arrows here so please forgive me. The current solution - which is not in production yet - is something like the following: Both systems will be queried and the controller will merge the results. The new system has its own proprietary query language (we've alleviated this a bit with a LINQ provider). It also puts a lot of data on the wire. 15 search results typically run about 60k of unintelligible SOAP-wrapped xml. So I would prefer to avoid querying this system directly. These two systems publish events to help us integrate with other systems, mainly an ERP system. One of these events contains all the data necessary for the search screen. I proposed the following alternative: However I am being told that 'adding another database' will create more maintenance down the road. However, I believe this to be false, as I had to add a relatively simple feature that took several hours longer than anticipated because of this merging code. I want to get a feel for which system is more maintainable in the long run. I personally have not had the burden of maintaining any large system. I want something more than my gut. Specifically I'd like to know if having more, specialized physical databases is more or less maintainable than having less larger physical databases.

• How to install again Update Manager after uninstalling it

  - by biezdar

  Ok, the thing is this I tried asking many times on few ubuntu forums how to deal with my non-responsive Update Manager, but all I was getting was the same stuff (run it from the terminal, run some lines, apt-get update blah blah). Nothing was helping. Eventually I went mad Windows style and tried to simply uninstall it and install it again. The problem is - how to install it again? Can't do it through Software Center, can't really build a package (because I'm too stupid to do that). And I seriously want to avoid reinstalling the whole system. I am running a 12.04 verison (Update Manager was unable to update to a newer one) Please help. I am furious with this thing.

• How to change the IP address on my Ubuntu virtual NIC

  - by DextrousDave

  I have a physical windows system, on which I run Vmware Workstation. Now on VMware I run Ubuntu 12.10. I am running a webserver on Ubuntu via LAMP, inside VMware. Problem: Now my local IP address for my virtual NIC (the one Ubuntu is using) has an address of 192.168.159.7, and my home router only issues IP addresses of the range 10.0.0.x. So if I want to port forward to the virtual NIC, which has a 192.168 address, I cannot, so my LAMP webserver cannot be accessed externally since the router does not know to send the packets on port 80 to the virtual NIC... How do I fix that? The only way I guess is to assign a 10.0.0.x ip address to the virtual NIC?? But how do I do that? I tried to do it on the host Windows machine with 'Get my IP address automatically' but it issues a 192.168 address every time... Thank you

• How can i fit 2 commands in 1 terminal shortcut

  - by Nicky Bailuc

  10 latest updates and drivers and I need to run a game called unreal tournament, but in terminal it requires 2 commands The first one is to mount into the folder: cd /usr/local/games/ut2004/ and then the second one is to open the actual game: sudo aoss ./ut2004 In one shortcut i can only fit 1 command but both don't fit in is there any way i can turn these 2 commands into one? Perhaps turni9ng on the desktop shortcut already mounted into the folder? Any help would be really appreciated because im getting kinda sick of using the terminal to run it every time.

• How to Send the Contents of the Clipboard to a Text File via the Send to Menu

  - by Jason Faulkner

  We have previously covered how to send the contents of a text file to the Windows Clipboard with a simple Send To shortcut, but what if you want to do the opposite? That is: send the contents of the clipboard to a text file with a simple shortcut. No problem. Here’s how. Copy the ClipOut Utility While Windows offers the command line tool ‘clip’ as a way to direct console output to the clipboard, it does not have a tool to direct the clipboard contents to the console. To do this, we are going to use a small utility named ClipOut (download link at the bottom). Simply download and extract this file to a location in your Windows PATH variable (if you don’t know what this means, just extract the EXE to your C:\Windows folder) and you are ready to go. Add the Send To Shortcut Open your Send To folder location by going to Run > shell:sendto Create a new shortcut with the command: CMD /C ClipOut > Note the above command will overwrite the contents of the selected file. If you would like to append to the contents of the selected file, use this command instead: CMD /C ClipOut >> Of course, you could make shortcuts for both. Give a descriptive name to the shortcut. You’re finished. Using this shortcut will now send the text contents copied to your Windows Clipboard to the selected file. It is important to note that the ClipOut tool only supports outputting text. If you had binary data copied to your clipboard, then the output would be empty. Changing the Icon By default, the icon for the shortcut will appear as a command prompt, but you can easily change this by editing the properties of the shortcut and clicking the Change Icon button. We used an icon located in “%SystemRoot%\System32\shell32.dll”, but any icon of your liking will do. As an additional tweak, you can set the properties of the shortcut to run minimized. This will prevent the command window from “blinking” when the send to command is run (instead it will blink in your taskbar, which is hardly noticeable). Links Download ClipOut Utility

• Booting 11.10 from USB stick on MacBook Pro 5,1 fails

  - by Helge Stenström

  I've created a bootable memory stick on a Windows computer, and tested it on an HP PC. It's made from a 64-bit image of Ubuntu 11.10, downloaded from http://www.ubuntu.com/download/ubuntu/download. When I boot from this memory stick, there is some kind of boot menu, where I can choose to run Ubuntu from the memory stick, or install. I select Run from memory stick. (the words may be wrong here, I'm taking it from memory.) From this point, the screen is black (but backlighted), and I can't do anything but turn off the computer. It gets hot, too. Has anyone been more successful than me? Are there known issues? The computer is a 15 inch MacBook Pro 5,1 (unibody, late 2008), 4 GB memory.

• Why are slower programming languages considered worse than faster ones?

  - by Emanuil

  Here's how I see it. There's machine code and it's all that the computers needs in order to run something. The computers don't care about programming languages. It doesn't matter to them if the machine code comes from Perl, Python or PHP. Programming languages exist to serve programmers. Some programming languages run slower then others but that's not because there is something wrong with them. It's often because they do more things that otherwise programmers would do and by doing these things, they do better what they are supposed to do - serve programmers. So why are slower programming languages considered worse than faster ones?

• Brocken package manager due to incorrect Banshee package

  - by user54974

  Sup, so, I'm not familiar with linux at all so help is much appreciated. I've been trying to boot my pc up from a live CD unsuccessfully. I get to the stage at which there are the options to test without installing or install or so on where I select 'Install Ubuntu.' Here it relays through some fast DOS commands until it reaches 'end trace' and then, eventually, 'Killed.' I have already got a functional 11.10 version installed, could this be a problem? The reason I am attempting a reinstall is because the package system is damaged inside 11.10, a problem I can't seem to solve. If I try to install any new software from within the software centre it tells me that two banshee extensions must be removed. I try to remove these from inside the terminal, using apt-get remove, which results in:** You might want to run apt-get -f install to correct these: The following packages have unmet dependencies. banshee-extension-ubuntuonemusicstore : Depends: banshee (>= 2.2.1) but 2.2.0-1ubuntu2 is to be installed E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution). The software centre suggests that I disable all third party repositories and run apt-get install -f I have done so but the package system remains damaged and apt-get install -fattempts to install banshee 2.2.1 but returns: Errors were encountered while processing: /var/cache/apt/archives/banshee_2.2.1-1ubuntu3_i386.deb E: Sub-process /usr/bin/dpkg returned an error code (1) I have also tried apt-get update (runs fine) and apt-get upgrade. The upgrade command apt-get upgrade results in: Reading package lists... Done Building dependency tree Reading state information... Done You might want to run ‘apt-get -f install’ to correct these. The following packages have unmet dependencies. banshee-extension-soundmenu : Depends: banshee (>= 2.2.1) but 2.2.0-1ubuntu2 is installed banshee-extension-ubuntuonemusicstore : Depends: banshee (>= 2.2.1) but 2.2.0-1ubuntu2 is installed E: Unmet dependencies. Try using -f. I seem to be going round and round in circles here! If only I could reinstall successfully. Only proposed updates (oneiric proposed) is not enabled.

• "Time Control" in a 2d Platformer

  - by Woody Zantzinger

  I am making a 2d platformer where the player can press a button, and restart the level, only their previous character will also run the level at the same time, like they are traveling back in time. I know other games have done this before, and the way I have thought of doing it is to make the game character have a set of actions (Idle, Jumping, Walking Left etc.) and then detect changes in those actions and log them into a list along with the game time. So then when I need the character to run the level again on its own, I can just go through the list changing its actions at the right time. Is this the best way to do it? Does anyone have any experience in this? Thanks.

• Naming conventions for newtype deconstructors (destructors?)

  - by Petr Pudlák

  Looking into Haskell's standard library we can see: newtype StateT s m a = StateT { runStateT :: s -> m (a, s) } newtype WrappedMonad m a = WrapMonad { unwrapMonad :: m a } newtype Sum a = Sum { getSum :: a } Apparently, there (at least) 3 different prefixes used to unwrap a value inside a newtype: un-, run- and get-. (Moreover run- and get- capitalizes the next letter while un- doesn't.) This seems confusing. Are there any reasons for that, or is that just a historical thing? If I design my own newtype, what prefix should I use and why?
