• Ubuntu on Thinkpad Edge 11/13/14/15

  - by lasseespeholt

  I think a community wiki on problems (and solutions) when installing Ubuntu (10.10) on a Thinkpad Edge 11 would be nice (because I just got one ;)). I'll contribute with my own problems and solutions, and hope others will join too. Thinkwiki entry for the Edge 11 Known problems: No wifi-driver, solution: answer #1, answer #2 Fan is loud, even though it's on auto. No solution. Thinkfan is a possible solution, but correction values for sensors should be supplied (mapping sensors to specific areas). Also, one sensor is between -100C and +100C - maybe some kind of deactivation would help. FN keys stop working: see below. No sound on headphones: see below.

• Your software-problem-solution approach

  - by Panoy

  Hi, I am unfamiliar with many software development philosophies/approaches such as these: DDD - Domain Driven Development Design TDD - Test Driven Development BDD - Behavior Driven Development Other 3-letter acronym that ends with "development" and many more My question is, when will you get to decide to choose what kind of philosophy/approach to follow? Espceially the top 3 approach in the list: What is TDD for? Why use DDD for this problem? Mainly your answer would be a case-to-case basis or maybe that there is no single universal philosophy/approach to consider. In that case, could you just tell me what type of project/scenario and why did you use that philosophy/approach.

• Is it worth it to learn some programming before college?

  - by Howlgram

  I'm in my last year of highschool and I am very interested in programming, the thing is I don't know if it could be worth it to start learning programming now, im afraid that when I get to college they might just teach all I might have learned in a few classes making a waste the time spent on learning that before college. Right now I'm on my last year of highschool and I know absolutely nothing about programming. There are other similar questions where people answer saying it is good to learn beforehand, but I doubt their situation might be like mine, maybe they had much more time to learn programming (as if they were not on their last year of highschool) before college so they could learn some serious skills, besides they say they already know at least the basics about a language, instead, I know nothing and I have no idea how much could I learn this year. If it wasn't clear I want to study computer's science

• A command-line clipboard copy and paste utility?

  - by Peter.O

  In Windows I used command-line clipboard copy-and-paste utilities... pclip.exe and gclip.exe These were UnixUtils ports for Windows (but they only handled plain text). There were a couple of other native Windows utils which could write/extracy any format. I've looked for something similar in Synaptic Package Manager, but I can't find anything. Is there something there, that I've missed? ... or maybe this is available in bash scripting? The type of utility I'd like will be able to read/write via std-in/std-out or file-in/file-out, and handle Unicode/Rich-text/Picture/etc clipboard formats... Late Edit: NB: I'm not after a clipboard manager.

• How can I receive more traffic? My VPS fails!!!

  - by Vic

  I have a web site - photo gallery. About 400 photos. Site on Gallery 3. mySQL. Hosted on VPS from myhosting.com (CPU 1792 MHz, 2048 MB RAM). Everything seems to be ok, but there is one big problem. Once traffic reaches ~ 20 people (online) - website start loading really really slow. Actually website can't be loaded about 30-60 sec. What should I do? Buy more RAM / CPU on the same VPS? Move to a dedicated server or maybe myhosting.com just sucks? What do you recommend?

• Why I can't see my desktop icons in ubuntu 13.04?

  - by Edgar

  I just installed Ubuntu 13.04 in my laptop Aspire-M3-5871TG, and I can't see anything (neither icons, ...). Only is visible the desktop background but I can open and work with the terminal. Maybe the problem is related with Nvidia Geforce GT 640M vs Unity. I've tried several commands: dconf reset -f /org/compiz/ unity --reset-icons &disown and unity --replace & but nothing happens. I've tried other commands as well: sudo add-apt-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get install nvidia-current and nothing happens. I've also tried to install tweak but is it not possible to find it. Thus, I can't do nothing ... Definetely my laptop is not compatible with Ubuntu 13.04?

• Too early to apply for post-graduation jobs?

  - by Rob Lourens

  I graduate in May 2012. I'm on an internship with one company right now that will probably make me an offer in August, but I will only have a couple weeks to take or leave it. I'm not sure whether I'll want to accept it- it will depend on the specifics. So I plan to apply for other jobs to see if I can get another offer, but would it be too early to be applying over the next few weeks when I wouldn't start until next May at least? I hate to turn down an offer having nothing else lined up. I'm a software engineer at one large software company and I would apply for jobs at other large software companies. I assume a smaller company would work on a much shorter hiring schedule, but maybe large companies wouldn't mind hiring 8-9 months in advance? I also hate to start applying any earlier than I have to- I know I'll only have more experience and be more employable with time.

• Pros and cons of the Google font API

  - by Seamus

  I am currently using a font from the google font directory on my website. I don't fully understand how it works, but it seems like when someone opens my site, their browser is told to go and fetch the font from Google. (correct me if I'm wrong). Now, what I'm wondering is, what are the pros and cons of this over just specifying a font family the old-school way? Presumably doing it the google font directory way has the advantage that they'll definitely see the font I want them to. (as long as the font directory is up). But does this way have disadvantages? Maybe using fonts that are stored locally speeds up the site loading?

• magic trackpad - Ubuntu

  - by UbuntuGuy

  I've been using a mac in my job for a while now. The only feature i like about it above my ubuntu (on an hp) is the trackpad. I love doing the strokes to move between different files. It really makes things quicker. Is it possible to imitate this feature on my ubuntu laptop. (like maybe there might be something that utilizes my mouse pad on the laptop, as well as the scroller) If that is impossible or doesn't exist then can i set up a magic trackpad to ubuntu on my hp.

• Repercussions to sharing .bashrc across machines with Dropbox?

  - by Alan Peabody

  I work on a lot of different machines, all running Ubuntu (not always the same version). I have some really basic customizations to my prompt I would like to have available on all machines. I currently use Dropbox and store all my other "dot files" there, such as my .vim/ .vimrc .gitconfig .ackrc. I then just link them to my home folder from my Dropbox folder. Voilà, all machines in sync. I am unsure what the repercussions of doing something like this with my bashrc is. Can any one offer suggestions? Maybe an easy way to load a separate file in the bashrc?

• forked-daapd without avahi

  - by vixducis

  I'm trying to setup forked-daapd, but i'd prefer it if i could run it without avahi (or rather define my own avahi service instead of using the dbus api). The reason is that i want a netatalk share for my time machine backups and a samba share for the symbolic link support (netatalk doesn't support symlinks). Those two are defined as different services in avahi. To make that work, i have to disable avahi's dbus api, or else netatalk tends to take over all the services (osx prefers afp over smb). If I now try to start forked-daapd, it just doesn't. Forked-daapd requires avahi's dbus api to be enabled and running. Is there some sort of way around this limitation, so that i can manually define my own daap service in avahi. Maybe something like enabling but ignoring the dbus in avahi, or launching a duplicate avahi daemon with a different config file?

• What happened this type of naming convention?

  - by Smith

  I have read so many docs about naming conventions, most recommending both Pascal and Camel naming conventions. Well, I agree to this, its ok. This might not be pleasing to some, but I am just trying to get you opinion why you name you objects and classes in a certain way. What happened to this type of naming conventions, or why are they bad? I want to name a struct, and i prefix it with struct. My reason, so that in IntelliSense, I see all the struct in one place, and anywhere I see the struct prefix, I know it's a struct: structPerson structPosition anothe example is the enum, although I may not prefix it with "enum", but maybe with "enm": enmFruits enmSex again my reason is so that in IntelliSense, I see all my enums in one place. Because, .NET has so many built in data structures, I think this helps me do less searching. Please I used .NET in this example, but I welcome language agnostic answers.

• Deterministic Multiplayer RTS game questions?

  - by Martin K

  I am working on a cross-platform multiplayer RTS game where the different clients and a server(flash and C#), all need to stay deterministically synchronised. To deal with Floatpoint inconsistencies, I've come across this method: http://joshblog.net/2007/01/30/flash-floating-point-number-errors/#comment-49912 which basically truncates off the nondeterministic part: return Math.round(1000 * float) / 1000; Howewer my concern is that every time there is a division, there is further chance of creating additional floatpoint errors, in essence making it worse? . So it occured to me, how about something like this: function floatSafe(number:Number) : Number {return Math.round(float* 1024) / 1024; } ie dividing with only powers of 2 ? What do you think? . Ironically with the above method I got less accurate results: trace( floatSafe(3/5) ) // 0.599609375 where as with the other method(dividing with 1000), or just tracing the raw value I am getting 3/5 = 0.6 or Maybe thats what 3/5 actually is, IE 0.6 cannot really be represented with a floatpoint datatype, and would be more consistent across different platforms?

• What algorithm(s) can be used to achieve reasonably good next word prediction?

  - by yati sagade

  What is a good way of implementing "next-word prediction"? For example, the user types "I am" and the system suggests "a" and "not" (or possibly others) as the next word. I am aware of a method that uses Markov Chains and some training text(obviously) to more or less achieve this. But I read somewhere that this method is very restrictive and applies to very simple cases. I understand basics of neural networks and genetic algorithms(though have never used them in a serious project) and maybe they could be of some help. I wonder if there are any algorithms that, given appropriate training text(e.g., newspaper articles, and the user's own typing) can come up with reasonably appropriate suggestions for the next word. If not (links to)algorithms, general high-level methods to attack this problem are welcome.

• Using macro keys with razer blackwidow ultimate 2013

  - by user119020

  I recently bought a Razer blackwidow ultimate 2013 keyboard. The keyboad contains 5 macro keys and according to the manual, they can be quickly set using the key combination fn+f9. However, this doesn't work; it won't record any macros. All the other function buttons on the keyboard work fine (e.g. volume up, volume down, stand-by) Does anyone know how I can enable those keys? Maybe an extra package. I am using 64 bit ubuntu 12.04 Thanks in advance :)

• In which object should I implement wait()/notify()?

  - by Christopher Francisco

  I'm working in an Android project with multithreading. Basically I have to wait to the server to respond before sending more data. The data sending task is delimited by the flag boolean hasServerResponded so the Thread will loop infinitely without doing anything until the flag becomes true. Since this boolean isn't declared as volatile (yet), and also looping without doing anything wastes resources, I thought maybe I should use AtomicBoolean and also implement wait() / notify() mechanism. Should I use the AtomicBoolean object notify() and wait() methods or should I create a lock Object?

• Complete Guide/Tutorials on LWJGL?

  - by user43353

  Dont get me wrong, I finished these tutorials on http://lwjgl.org/wiki/index.php?title=Main_Page. I finished The Basics section, OpenGL 3.2 and newer section, and I looked at the Example Code section. They were great tutorials, and I have looked at the external tutorials as well. I don't know where to go from here, and OpenGL is not my strong point. Some one suggested Learning Modern 3D Graphics Programming, and I didnt learn much. I looked at the port to LWJGL, but the book was on C and I couldn't really understand what the OpenGL meant. I am trying to learn 2D gaming, not 3D. Maybe later. Is there any tutorials that aren't C/C++ heavy and teach you 2D OpenGL?

• Formalizing programmers errors

  - by Maksee

  Every one of us make errors leading to bugs. Once I wanted to start logging my errors for future analysis, probably mentioning project title, approximate time spent and the most important, the type of error. For example when I copy-pasted a fragment about 'x' and replaced every occurrence of 'x' with 'y' and forgot to replace a tiny piece, this goes to 'copy-paste error'. The usefulness of this approach depends on whether I can formalize my errors at all and probably minimizing the number of types to choose from. Otherwise I would start postponing, ignoring and so on so make this system useless. Are there existing research in this area, probably a known minimum set of errors? Maybe some of you already tried to implement something like this and succeeded/failed?

• How to make a great functional specification

  - by sfrj

  I am going to start a little side project very soon, but this time i want to do not just the little UML domain model and case diagrams i often do before programming, i thought about making a full functional specification. Is there anybody that has experience writing functional specifications that could recommend me what i need to add to it? How would be the best way to start preparing it? Here i will write down the topics that i think are more relevant: Purpose Functional Overview Context Diagram Critical Project Success Factors Scope (In & Out) Assumptions Actors (Data Sources, System Actors) Use Case Diagram Process Flow Diagram Activity Diagram Security Requirements Performance Requirements Special Requirements Business Rules Domain Model (Data model) Flow Scenarios (Success, alternate…) Time Schedule (Task Management) Goals System Requirements Expected Expenses What do you think about those topics? Shall i add something else? or maybe remove something?

• Very few visitors on Analytics: incorrect setting?

  - by Akaban

  it's quite a long time Analytics is making me crazy: I have a 2 years old website, started with Aruba (an Italian provider) and then transfered on Hostgator. It's a blog Wordpress + MyBB forum, and on both the platforms I've the Analytics code in the footer. The problem is that the stats on Analytics are simply ridiculous compared to the numbers reported by the Aruba (before) and Hostgator (then). I think that the numbers of Aruba/Hostgator are correct, simply because just the daily users connected on the forum is higher than the Analytics numbers. I know it's a really confused request, but maybe you can help me to understand what's the problem.

• How do I get rid of the drive mount confirmation question for sshFS on boot?

  - by Dave M G

  With help from this site, I was able to set up an SSHFS connection between two computers on my LAN so that one auto mounts on the other at boot time. Everything works, but there is this annoying confirmation that comes up whenever I boot: An error occurred while mounting /home/dave/Mythbuntu. Press S to skip mounting or M or Manual recovery If I press S, then booting continues, and my drive is mounted as hoped, so it seems like even though I "skipped" it, maybe it tried again and succeeded later in the boot process. I followed the instructions here to set up "if up / if down" scripts, and here is my current /etc/fstab: sshfs#[email protected]:/home/mythbuntu /home/dave/Mythbuntu fuse auto,users,exec,uid=1000,gid=1000,allow_other,reconnect,transform_symlinks,BatchMode=yes 0 0 Although the mounting is working, this step of having to press S every time I boot is obviously kind of a hassle. How do I configure my computer so I don't have to do that, and so that my other computer will still automount?

• How do I share different files in a git repo with different people?

  - by David Faux

  In a single directory with a Git root folder, I have a bunch of files. I am working on one of those files, X.py, with my friend Alice. The other files I am working on with other people. I want Alice (and everyone else) to have access to X.py. I want Alice to only have access to X.py though. How can I achieve this with Git? Is there a way I can split a directory into two repos? That sounds rather cumbersome. Maybe I could add a remote repo that Alice can access containing X.py?

• Resources on learning to program in machine code?

  - by AceofSpades

  I'm a student, fresh into programming and loving it, from Java to C++ and down to C. I moved backwards to the barebones and thought to go further down to Assembly. But, to my surprise, a lot of people said it's not as fast as C and there is no use. They suggested learning either how to program a kernel or writing a C compiler. My dream is to learn to program in binary (machine code) or maybe program bare metal (program micro-controller physically) or write bios or boot loaders or something of that nature. The only possible thing I heard after so much research is that a hex editor is the closest thing to machine language I could find in this age and era. Are there other things I'm unaware of? Are there any resources to learn to program in machine code? Preferably on a 8-bit micro-controller/microprocessor. This question is similar to mine, but I'm interested in practical learning first and then understanding the theory.
