  - by GUI Junkie

  At this moment, ever since I installed Ubuntu on this machine, the battery status says: not present. Looking at this answer, however, I find that /proc/acpi/battery/BAT1/info (sometimes its /proc/acpi/battery/BAT0/info, use tab complete to help) has the following info: present: yes design capacity: 4400 mAh last full capacity: 4400 mAh battery technology: rechargeable design voltage: 11100 mV design capacity warning: 300 mAh design capacity low: 132 mAh cycle count: 0 capacity granularity 1: 32 mAh capacity granularity 2: 32 mAh model number: BAT1 serial number: 11 battery type: 11 OEM info: 11 In accordance to this answer, I've checked the /proc/acpi/battery/BAT1/state file: present: yes capacity state: ok charging state: charged present rate: unknown remaining capacity: unknown present voltage: 10000 mV The acpi -b command returns: Battery 0: Unknown, 0%, rate information unavailable Any suggestions on getting the battery info updated?

• Windows 8 and Ubuntu 12.10 dual boot

  - by Marty

  I have been having a tough time getting a new computer (Lenovo h430) that came with windows 8 to dual boot with ubuntu linux. I can get ubuntu to install from a usb drive and can use the live system (ubuntu 12.10) but dual booting has not worked. I have cruised the internet and tried a number of solutions such as easybcd 2.2 and boot repair under linux. I have also gone into the setup screen to try and fix it but the lenovo acromyms in the setup are not illuminating for me. Does anyone know of a clear set of instructions for installing ubuntu on a machine delivered with windows 8 ?

• Which programming language suits a system that must work without user input

  - by Ruud

  I'm building a prototype of a device that will function much alike a digital photoframe. It will display images retrieved from the internet. The device must start up and run the photoframe. It will have no user interface. The device has a minimal ubuntu installation, but I could install Xorg or whatever needed. Question: I have trouble figuring out which programming language will be suitable. I've just started using Python to try out several things and I am able to download and display images. I guess that means Python can do what I'd like, but is it suitable as a language that will be run on boot without any user interference? Related questions: - How do I set up Linux to start that script automatically? - How to setup a second Python script as a server that runs in the background to retrieve images before they are displayed (Because I think I'll need threading of some sort?)

• 14.04 Chinese Ibus Input - No Options

  - by RhZ

  getting my new 14.04 rig going ;-) Pretty happy with it, everything seems to be working great. For Chinese input, however, having a problem. I went through the typical steps, open language in settings, let it install some stuff, then add Chinese and choose Ibus. Then, after logging in and out, I see the language icon in my system tray. However, when I go to add the Chinese into Ibus, it only lets me choose "Chinese", which isn't an input method. It should give me a bunch of choices like pinyin, bopomo or whatever, I only use pinyin so don't know those names. I saw someone online had a little command which helped people with similar problems, but it did not work for me, even after a re-start. So, anyone got a solution? Edit: Here is what it looks like, just "Chinese" in the list, when there should be a bunch of input options like pinyin, potomofo, and so on.

• Outline Shader Effect for Orthogonal Geometry in XNA

  - by Griffin

  I just recently started learning the art of shading, but I can't give an outline width to 2D, concave geometry when restrained to a single vertex/pixel shader technique (thanks to XNA). the shape I need to give an outline to has smooth, per-vertex coloring, as well as opacity. The outline, which has smooth, per-vertex coloring, variable width, and opacity cannot interfere with the original shape's colors. A pixel depth border detection algorithm won't work because pixel depth isn't a 3.0 semantic. expanding geometry / redrawing won't work because it interferes with the original shape's colors. I'm wondering if I can do something with the stencil/depth buffer outside of the shader functions since I have access to that through the graphics device. But I don't believe I'm able to manipulate actual values. How might I do this?

• How can I stop LibreOffice from randomly crashing?

  - by Sam Mercier

  Libreoffice keeps on crashing randomly. It will do this when I am typing and when I am switching desktops or anything. There is no patter to it. I need some help here. Anyone had this problem or problem similar to it? Anyone have found a fix. Also it seems to happen especially prominently after my screensaver has started. I would say it happens about 97% of the time after that. This is an annoying bug and is keeping my productivity low.

• Are there any specific workflows or design patterns that are commonly used to create large functional programming applications?

  - by Andrew

  I have been exploring Clojure for a while now, although I haven't used it on any nontrivial projects. Basically, I have just been getting comfortable with the syntax and some of the idioms. Coming from an OOP background, with Clojure being the first functional language that I have looked very much into, I'm naturally not as comfortable with the functional way of doing things. That said, are there any specific workflows or design patterns that are common with creating large functional applications? I'd really like to start using functional programming "for real", but I'm afraid that with my current lack of expertise, it would result in an epic fail. The "Gang of Four" is such a standard for OO programmers, but is there anything similar that is more directed at the functional paradigm? Most of the resources that I have found have great programming nuggets, but they don't step back to give a broader, more architectural look.

• Crontab opens as blank page, cannot save

  - by Sarah

  I am really not familiar with linux, and only started using it recently, so be patient with me. I am trying to control a camera on regular intervals through a script that is called upon in the crontab. When I start up the computer, I can open crontab, edit and save, and everything is executed correctly. However, I can never open crontab a second time, unless I restart the computer first. If I type crontab -e, I get a blank page, located in the /tmp directory. I can enter my commands in there, but cannot save it. I don't know if this is relevant, but when I try sudo crontab -e, I get something like "no cron installed for root". Any help is really appreciated! Sarah

• Unable to login following permission changes in device manager (11.10 + Gnome)

  - by Symanuk

  (Running Gnome 3 on Ubuntu 11.10) Everything working well (at least a couple of months), until recently when I changed the permissions through the device manager on the sda1 /2/ 3 drives, thinking it would save all the switching I seem to have to do between users in order to see / use files I previously copied across from an external drive. Now when I boot up the Ubuntu splash screen loads indefinitely, and if I go in through the GRUB / recover option, i'm getting a load of negative permission messages back (regardless of using the fsck or remount options) Either way = unusable machine (Laptop Dell Inspiron n5050), and no way through to login. I'm looking for: (1) a way back in so any help greatfully received (answers need to be pretty basic as i'm a novice), and (2) if i'm to learn anything, a decent thread on setting permissions within Ubuntu / Gnome 3. I'm new to both Ubuntu & Linux, so please be gentle!! Cheers

• Am I bored with programming? [closed]

  - by user1167074

  I have started programming 2 years back and I have learnt web programming while working for big corporate companies. I was very passionate and I even did couple of side projects which were well appreciated by my friends and colleagues. But for the past 2 months I am not doing anything really interesting with programming, even if I get good ideas I am not feeling like coding, sub consciously I am feeling like "So What?" if I do this project. I would like to know from the more experienced programmers if this is just a phase or am I really missing something? Thanks

• How can I manage changes between a local config file and a remote config file in a mobile application?

  - by hib

  I have an application with a configuration file that is stored in the application bundle. This config file stores the names of images on a remote server. Whenever the application is started, I download the configuration file from the server and see if there are any changes or updates. If there are changes, I iterate over the array of configuration settings and download the changed images to the user's iPhone I think that I will first list all of the name changes in an array, and after that start loading that changed images. However, I'm wondering if there is a better approach to solving this problem.

• UDK/ UnrealScript class interaction? HUD advice?

  - by Holly

  Beginner basics requested here, While i'm familiar with the basics of OOP programming i've just started looking as UnrealScript for a game i had made in the UDK editor up to now. I have a class that extends UTHUD and another that extends UDKPAWN. I have the pawn destroyed when its been shot 3 times and some basic helloworld text displaying in my HUD but i'm completely lost as to how one would get some sort of feedback between the two classes going on? What i would like to do to start off, is have some text that says something like "Amount of baddies killed: 0" Displayed on the HUD which would then increment each time the player destroyed one of my pawns. I'm sorry if this is an inappropriate question but i've never really worked within a framework like this before and wasn't sure where to go for help to get my footing. All advice appreciated!

• Static HTML to Wordpress Migration SEO Implications?

  - by Kayle

  Recently, I migrated a client's site to a new server and a new home within wordpress so they could more easily edit their website and start a blog section. The static site was 10 years old a was showing up at place #3 for it's primary keyword, consistently, according to my client, and has dropped to rank #6-8 following the migration. At launch, we made sure the urls were identical (save the removal of ".htm" which we used 301 redirects to compensate for) and we generated a new XML map and pinged google with the new site. We keep a 404 log to make sure we're not losing any incoming links. We also have Google Webmaster Tools on this site and have zero errors/suggestions, everything seems ok. I was told by numerous sources that Google would not penalize us for the use of 301s, but it's the only thing I can think of right now that is different about the site, other than the platform. Any ideas about what we could be getting docked for?

• Basic Ubuntu FTP Server

  - by JPrescottSanders

  I would like to setup a basic FTP server on my Ubuntu Server install. I have been playing with VSFTPD, but am having issues getting the server to allow me to create directories and copy files. I have set the system to allow local users, but it appears that doesn't mean I get access to create directories. This may be an instance where I need to be better grounded in Unbuntu server setup in order to configure this FTP server adequately. The end goal is to be able to move files from my local dev folder into my www folder for deployment. Directories need to be able to move as well. Any help would be greatly appreciated.

• How To Troubleshoot Internet Connection Problems

  - by Chris Hoffman

  Internet connection problems can be frustrating. Rather than mashing F5 and desperately trying to reload your favorite website when you experience a problem, here are some ways you can troubleshoot the problem and identify the cause. Ensure you check the physical connections before getting too involved with troubleshooting. Someone could have accidentally kicked the router or modem’s power cable or pulled an Ethernet cable out of a socket, causing the problem.

• Making a collision detection system

  - by Sri Harsha Chilakapati

  I'm very new to game development (just started 3 months ago) and I've learning through creating a game engine. It's located here. In terms of collision, I know only brutefoce detection, in which case, the game slows down if there are a number of objects. So my question is How should I program the collisions? I want them to happen automatically for every object and call the object's collision(GObject other) method on each collision. Are there any new algorithms which can make this fast? If so, can anybody6 sh6ed some light on this topic? And I think of making it like the game maker Thanks

• unmet dependencies updating Intel graphics driver

  - by Nick Jacobs

  I am trying to update my graphics driver by running: sudo apt-get install xserver-xorg-video-intel But I keep getting this message: 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. The following information may help to resolve the situation: The following packages have unmet dependencies: xserver-xorg-video-intel : Depends: xorg-video-abi-11 E: Unable to correct problems, you have held broken packages. When I run: sudo apt-get install -f Nothing happens, because the program doesn't even get half way to installing. I am running Lubuntu 12.04 on a HP Mini 110 netbook. I have tried changing to several different ppa's but that doesn't work. I want to update my driver so that my mouse stops flickering and ScummVM stops flickering every minute.

• .NET Reflector Open Source Alternative

  - by bconlon

  When I found out yesterday that one of my top 5 development tools .NET Reflector will no longer be free at the end of February, I thought I'd see if work had started on a good open source alternative...and guess what...work on ILSpy is already well underway!! There seems to be a difference of opinion on what Red Gate said when they purchased .NET Reflector from Lutz Roeder in 2008. They say that they would try to keep it free, where as others think they promised to keep it free. Either way at the time I thought it was a smart purchase by Red Gate as it would raise their profile overnight within the .Net community. But not only are they going to charge $35 for v7 (which is up to them), they have also time-bombed v6 to force users to pay. This I think will lower their profile overnight within the .Net community!! Maybe they are been slightly naive in thinking the community wouldn't just write an alternative?  #

• "sudo apt -get install foo-" causes removing foo package and everything depends on it

  - by M.Elmi

  While working in command prompt, I accidentally typed following command: sudo apt-get install python3- and ubuntu started removing python3 and everything depends on it (including firefox and much more). Fortunately I closed that terminal immediately and reverted everything by checking dpkg log file, but I was wondering why an install command should act like remove? Is it a bug? Consider the situation that you are looking for a package name (pressing Tab twice) and going through possibilities by pressing Enter key and those Enter keys remain in the keyboard buffer and.... youhaaaa... apt-get is removing the entire installation in front of your eyes.

• SEI Turns Software Architecture into a Game

  - by Bob Rhubart-Oracle

  "Architecture is the decisions that you wish you could get right early in a project." -- Ralph E. Johnson Unless you can see into the future, getting those decisions right comes down to a collection of hard choices. But the Software Engineering Institute (SEI) of Carnegie Mellon University has turned those hard choices into a game. Literally. According to the SEI website: The Hard Choices game is a simulation of the software development cycle meant to communicate the concepts of uncertainty, risk, options, and technical debt. In the quest to become market leader, players race to release a quality product to the marketplace. By the end of the game, everyone has experienced the implications of investing effort to gain an advantage or of paying a price to take shortcuts, as they employ design strategies in the face of uncertainty.   Check it out for yourself: Download the Hard Choices Board Game Download the companion white paper: The Hard Choices Game Explained
