  • Can't fix broken packages using Synaptic (Broken Package: Wine1.4)

    - by Rustyblade
    Ok so I am trying to fix a broken package in order to install wine. When I do "sudo apt-get install wine" I get: sam@ubuntu:~$ sudo apt-get install wine [sudo] password for sam: Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.

  • How do I rename a mounted Truecrypt volume?

    - by invert
    When I mount the Truecrypt file on my USB drive it shows up as truecrypt1. The volume is FAT, using mtools to rename a volume label involves e2label /dev/sdbx, however truecrypt1 does not map to a physical partition. fdisk -l does not show the volume partition (only the physical USB device), and df -h lists the volume path as /dev/mapper/truecrypt1. Finally, using the Nautilus 'Rename' context action, gives the error: "Sorry, could not rename "truecrypt1" to "towel": Operation not supported by backend". Apparently this can be done in Win, but how can I rename this volume in Ubuntu? As Nicolas said, specifying the mount point names the partition the same. The truecrypt GUI does not remember the mount point I set, so I specify the mount points in a script which I placed in my main menu. #!/bin/bash gksudo truecrypt /media/usbdrive/encryptedfile /media/securedata/

  • What functional language is most suited to create games with?

    - by Ricket
    I have had my eye on functional programming languages for a while, but am hesitating to actually get into them. But I think it's about time I at least starting glancing that direction to make sure I'm ready for anything. I've seen talk of Haskell, F#, Scala, and so on. But I have no clue the differences between the languages and their communities, nor do I particularly care; except in the context of game development. So, from a game development standpoint, which functional programming language has the most features suited for game programming? For example, are there any functional game development libraries/engines/frameworks or graphics engines for functional languages? Is there a language that handles certain data structures which are commonly used in game development better? Bottom line: what functional programming language is best for functional game programming, and why? I believe/hope this question will declare a clear best language therefore I haven't marked it CW despite its subjective tendency.

  • Problems about responsiveness and keyboard/mousepad not working

    - by ChrisTheNoob
    So I installed Ubuntu 12.04, I'm very new at this and want to get into the world of Linux but have run into nothing but problems. I have an Acer Aspire 5553g. First off, my keyboard won't work. Second, my computer has more than enough of everything to run Ubuntu smoothly, but everything runs extremely slow. (You move the mouse and it gets there a few seconds later) It's to the point where I can't even use it and I really want to. I'm tired of Microsoft stuff and I've been looking at learning how to use Linux based operating systems for a while. Please send me some help to fix these issues and maybe some tips to help get me started. Thanks in advance chris

  • How do I install xulrunner in 12.04?

    - by chessplayer
    I am trying to migrate a virtual machine I use for my classes at the university from 10.04 to 12.04 and in that I am using xulrunner so that first, I can have SQLiteManager as a stand alone app next, KNIME can provide help for its nodes I tried adding the the mozilla ppa as described in some posts, e.g. here or here, but when I search for xulrunner in Synaptic I get no match. I read in this link, that xulrunner was left out intentionally, which, frankly, I think is a bad decision! Anyway, does anyone know a way out of this, i.e. how to get xulrunner for 12.04? Any help appreciated!

  • Problem with NVIDIA G86 on Kubuntu 12.04

    - by Stefan
    I got problems some weeks ago with my NVIDIA G86 (8500 GT), supposedly due to the infamous 295.40 version of the driver. I got errror messges like NVRM: RmInitAdpterFailed. Tried varous sugestions about setting kernel acpi and memory options, but no luck. I pulled in x-swat and got 302.17, if I remember correctly. It did not help. People recommended xorg-edgers , so I pulled that in and got kernel 3.5.0.12 and nvidia 304.43 but the problem remained. Getting slightly panicked, I tried to back back to vanilla 12.04, so I purged nvidia* and located and removed anything on the system that smelled nvidia. I installed nouveau, cause people said it was great, but as it turns out, my card does not seem to be supported. :-( Sigh... So now I fear that I have atmessed up system, and graphics is terrible. Any help would be appreciated. Xorg.0.log: http://paste.ubuntu.com/1189616/ kern.log: http://paste.ubuntu.com/1189634/

Bring up the config.cmd, choose update existing domain. 5: Update the domain using the template that just generated. Go through the Configuration wizard.

  • Question about server usage, big community platform

    - by Json
    I’m working on a community platform writen in PHP, MySQL. I have some questions about the server usage maybe someone can help me out. The community is based on JQuery with many ajax requests to update content. It makes 5 - 10 AJAX(Json, GET, POST) requests every 5 seconds, the requests fetch user data like user notifications and messages by doing mySQL queries. I wonder how a server will handle this when there are for more than 5000 users online. Then it will be 50.000 requests every 5 seconds, what kind of server you need to handle this? Or maybe even more, when there are 15.000 users online, 150.000 requests every 5 seconds. My webserver have the following specs. Xeon Quad 2048MB 5000GB traffic Will it be good enough, and for how many users? Anyone can help me out or know where to find such information, like make a calculation?

  • How to keep a team well-trained?

    - by PierrOz
    Hi dear fellows, I'm currently mentoring a small team of 4 junior dev in small software company. They are very smart and often achieve their tasks with a high-quality job but I'm sure they still can do better - actually I have exactly the same feeling for myself :) -. Besides some of them are more "junior" than other. So I would like to find of a funny way to improve their CS skills (design, coding, testing, algorithmic...) in addition to the experience they acquire in their daily work. For instance, I was thinking of setting up weekly sessions, not longer than 2 hours, where we could get together to work on challenging CS exercises. A bit like a coding dojo. I'm sure the team would enjoy that but is it really a good idea? Would it be efficient in a professional context? They already spend all their week to code so how should I organize that in order for them to get some benefits? Any feedback welcome !

    I'm doing this question because I can't edit other questions and I'm trying to set up my computer with Ubuntu but I'm a total idiot about this. I want to give Ubuntu a try, I build up a system specially for Ubuntu but when everything seems to be OK I made a suggested update and now when I restart my computer Ubuntu is stuck in the purple screen.

My keyboard shutdown when this happens and only accepts Alt-Ctrl-Del to reboot again. Ctrl-F4 is not working for me. Pleas Help Me, cure my MS insanity Pleaseee! :) Any help I will appreciate it!

  • Documenting user interfaces in a mouse-less touch UI

    - by Daniel Cazzulino
    “Old” apps rely on mouse pointing and tooltips to explain what a given button is for. Maybe there is text associated with the button, but you can only put so much text without wasting useful screen state. More so in a phone or tablet app. I’ve seen a trend in Google apps where they put an overlay on top of the app the first time it runs, to explain how the various pieces of UI work. I have seen this also on my Nexus phone, but don’t have a screenshot. I don’t recall a way to actually bring that help overlay back again, so that’s maybe some built-in gesture that’s missing. Here’s what it looks like in Gmail, the first time you use the new compose layout:   I like the approach very much, and I think it’s something that should become standard part of mobile OS, and Windows, including a standard way to bring that help up from within any app....Read full article

  • Not Quite Multiseat

    - by user2773520
    I am attempting to create a pair programming environment sort of set up like multiseat: https://help.ubuntu.com/community/MultiseatX[1] or https://help.ubuntu.com/community/MultiseatOneCard[2] (as the standard issue boxes only have one graphics card) The thing is, I only want one login session, just with 2 monitors, keyboards, and mice. As well as having 2 active applications (so 2 people can be typing independantly). They should ideally be able to mouse over and click & type in the other persons monitor, as well as move windows between the montors. Does anybody know of anything like this that will work? We are running Ubuntu 12.04.

  • 5 ways to stop code thrashing&hellip;

    - by MarkPearl
    A few days ago I was programming on a personal project and hit a roadblock. I was applying the MVVM pattern and for some reason my view model was not updating the view when the state changed??? I had applied this pattern many times before and had never had this problem. It just didn’t make sense. So what did I do… I did what anyone would have done in my situation and looked to pass the blame to someone or something else. I tried to blame one of the inherited base classes, but it looked fine, then to Visual Studio, but it seemed to be fine and eventually to any random segment of code I came across. My elementary problem had now mushroomed into one that had lost any logical basis and I was in thrashing mode! So what to do when you begin to thrash? 1) Do a general code cleanup – Now there is a difference between cleaning code and changing code . When you thrash you change code and you want to avoid this. What you really want to do is things like rename variables to have better meaning and go over your comments. 2) Do a proof of concept – if cleaning code doesn’t help. The  you want to isolate the problem and identify the key concepts. When you isolate code you ideally want it to be in a totally separate project with as little complexity as possible. Make the building blocks and try and replicate the functionality that you are getting in your current application. 3) Phone a friend – I have found speaking to someone else about the problem generally helps me solve any thrashing issues I am having. Usually they don’t even have to say anything to solve the problem, just you talking them through the problem helps you get clarity of mind. 4) Let the dust settle – Sometimes time is the best solution. I have had a few problems that no matter who I discussed them with and no matter how much code cleaning I had done I just couldn’t seem to fix it. My brain just seemed to be going in circles. A good nights rest has always helped and often just the break away from the problem has helped me find a solution. 5) Stack overflow it – So similar to phone a friend. I am really surprised to see what a melting pot stack overflow has been and what a help it has been in solving technology specific problems. Just be considerate to those using the site and explain clearly exactly what problem you are having and the technologies you are using or else you will probably not get any useful help…

  • How can I maximally compress .gz files in Nautilus?

    - by Takkat
    When selecting Compress... from the right click context menu in Nautilus I am able to quickly compress files to .gz format. However by default Nautilus does not use maximum compression. Can I make Nautilus to use maximum compression like gzip -9? Using gconftool or gconf-editor to set the compression_level for File Roller to maximum seems right but infortunately has not the desired effect and will not lead to maximum compressed files. As this is the expected way of how to set compression levels a bug report has been filed upstream. Any ideas for a workaround are welcome.

  • Broken Links in different browsers

    - by kdorival
    Hi I'm having problems with our website, http://www.accessiblehomehealthcare.com, which is a wordpress 2.7 (version). All of a sudden our RSS links broke on the right side, which has happened before and I fixed it within 5 mins. Now, when I fix it, it doesn't look right in different version of I.E. or Firefox, I have I.E. 8 and Firefox 3.6.15 and it looks good for the most part, but there are a few parts where the links are broken. One browser the links would look ok but go to another page and the links or logos would be broken. Certain parts of the website should be static(identical) to the other pages of the site, but if a link is broken on one page, its perfect on another page. I was wondering was there a secret code for wordpress to keep the sites compatible with all browser versions or is there a bigger issue???? Any help or suggestions will help???
