• incorrect work gnome terminal

  - by Flatline

  I use at work Ubuntu Desktop 12.04. 80% of the time I spend in the terminal. After switching from the putty on gnome terminal, I was unpleasantly surprised to work with some devices (eg Extereme Summit X650): gnome terminal: # Module lldp configuration. Press <SPACE> to continue or <Q> to quit: after press SPACE: # Module lldp configuration. Press <SPACE> to continue or <Q> to quit:[60;D# # # Module msdp configuration. # putty(Windows and Linux)/konsole # Module lldp configuration. Press <SPACE> to continue or <Q> to quit: after press SPACE: # Module lldp configuration. # # # Module msdp configuration. # How to fix the gnome terminal?

• Wireless network unstable and often WPA2 protected networks just don't work

  - by Pedro

  I have an issue with my wireless network,so that the connection is working for only a few minutes, after which my browser no longer is able to load pages, even if the wireless is still active/connected. Furthermore, most of the time WPA2-personal protected networks don't work, (yesterday was the first time it worked - for a few minutes). By "don't work" I mean that it seems to successfully connect, but the browser can't load pages. I am running Ubuntu 10.10 32bit, and my wireless card is a RaLink rt3090. No changes have been done to any settings since Ubuntu was installed - networking began working on its own after the installation - but as described in first paragraph not very well.

• Recommendations for finding part-time consultancy work

  - by Mark Heath

  Although I have a full-time development job, I have occasionally done some part-time paid work in evenings / weekends for various people who have contacted me as a result of open-source projects I have worked on. It's a nice way to earn a bit of extra cash, but obviously it is not always available. My question is, what is a good way of getting your name out there to do some small projects? I have seen a few programmers-for-hire type websites, but I don't know which I can trust or whether there are too many people willing to work for very low prices. Also, being UK based, I would want something which did not assume I have a US bank account.

• Reasons why crontab does not work

  - by Adam Matan

  Many a time and oft, crontab scripts are not executed as expected. There are numerous reasons for that, for example: wrong crontab notation, permissions, environment variables and many more. This community wiki aims to aggregate the top reasons for crontab scripts not being executed as expected. Write each reason in a separate answer. Please include one reason per answer - details about why it's not executed - and fix(es) for that one reason. Please write only cron-specific issues, e.g. commands that execute as expected from the shell but execute erroneously by cron.

• xmonad keyboard doesn't work

  - by Mikkel Paulson

  I'm experimenting with xmonad, which I installed from the Ubuntu Software Centre on Ubuntu 12.10. It looks cool, but when I invoke it (using xmonad --replace from the command line) my title bars disappear and my keyboard stops working. At all. The terminal stops working, the keystrokes I've seen in online "getting started" guides are ignored, and the only way for me to actually power the system off is to hit the reset button or ssh in from my phone. Ironically, my mouse still works. One guide I saw suggested replacing the default window environment with xmonad, but I'm afraid of rendering my system completely inoperable if I do that. Any suggestions?

• window title bar and controls (minimize, maximize and close) don't work sometimes

  - by Ravindranath

  I am using Ubuntu 11.10. Sometimes the window controls don't work. If I click on any of the icons on top-right or top-left they just become colorless and fade away, as though that are not present. The window has not frozen, as I can click inside the window and continue to work with it. The moment I click inside the window the titlebar controls regain their color, but when I click them again, they fade and bcm colorless. As a result, I cannot close, minimize or maximize. This is not a continuous problem, but happens very frequently.

• Numlock doesn't work after logging in

  - by Tobi

  I've a strange problem after upgrading to Ubuntu 11.10 The Numlock of my Apple Keyboard (white, wired) doesn't work anymore. Strange thing because it works with the guest account but not with my user account. I did change the lightdm.conf to get the numlock working for the login and it works, but nor in my user account. Even stranger, pushing zero effects a right click? I also tried different keyboard layouts, but it shows Numlock on (stuck on) but doesn't work. Any idea which config file stores information about this?

• Dealing with frustration when things don't work.

  - by John Isaacks

  You ever try to implement something simple but for some strange reason it doesn't work. So you try a possible solution but then something else doesn't work. You keep trying different workarounds but every time something different isn't working. Every time you get one step closer you also get one (or more) step farther from solving this problem and its now been 3 hours when this should have taken you 10 minutes. And it still isn't solved. There is no one in your company who can help, and you are about to put your fist through your screen. At this point you are so frustrated you can no longer think about the problem clearly. What should you do at this point? Or what can you do to avoid reaching this point?

• What issues are there for doing freelance work?

  - by Telos

  I'm considering doing some contract work on the side of my normal job. I know that it will kill my free time, but I figure I can control when I'm doing projects and then get a little extra money or even eventually make it my full time job. But as I've never done this before, I'm wondering what issues people face to do this kind of work. For instance: how do you find customers? What difficulties do you normally face on a project? How do you deal with projects that are too large for one programmer to effectively complete? What about projects that need other skill sets (for instance web design for a web app?)

• Why to let / not let developers test their own work

  - by pyvi

  I want to gather some arguments as to why letting a developer testing his/her own work as the last step before the product goes into production is a bad idea, because unfortunately, my place of work sometimes does this (the last time this came up, the argument boiled down to most people being too busy with other things and not having the time to get another person familiar with that part of the program - it's very specialised software). There are test plans in this case (though not always), but I am very much in favor of making a person who didn't make the changes that are tested actually doing the final testing. So I am asking if you could provide me with a good and solid list of arguments I can bring up the next time this is discussed. Or to provide counter-arguments, in case you think this is perfectly fine especially when there are formal test cases to test.

• Part-time work as a beginner programmer [on hold]

  - by Valentas

  I wrote to one company near my university (starting in September) and they responded that they will probably hire me from the work I have already done (some projects and Euler problems solving). It's for 15 hours/week or so in order to not fall behind uni work. They require Python, SQL, XML and a good idea about how the Web works. The job role involves acquiring data from the Web and supplying it as search results for flight seekers (people). I am eager to learn but still, what can I do to become prepared for this? I ask because I tend to gravitate from one technology to the other, trying out things but never mastering it properly. What Web technologies are involved in such a job role? I have two months and want to learn as much as possible because there is much info but I have no idea where to start.

• wlan0 (WPA2) doesn't work when configured manually

  - by 71GA

  I have been trying to reconfigure my eth0 and wlan0 interfaces by editing /etc/network/interfaces file as folows: auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 192.168.1.11 gateway 192.168.1.1 netmask 255.255.255.0 network 192.168.1.0 dns-nameservers 193.2.1.66 auto wlan0 iface wlan0 inet static address 192.168.1.10 gateway 192.168.1.1 netmask 255.255.255.0 network 192.168.1.0 dns-nameservers 193.2.1.66 wpa-driver wext wpa-ssid lausi wpa-ap-scan 2 wpa-proto RSN wpa-pairwise CCMP wpa-group CCMP wpa-key-mgmt WPA-PSK wpa-psk 8952a447c860d13847ba1cabd15314ba9caf2fb207f19598f90c43fcd43c0d97 But my wireless doesnt work when i use command /etc/init.d/networking restart and when i do this i get an error: * Running /etc/init.d/networking restart is deprecated because it may not enable again some interfaces * Reconfiguring network interfaces...

• External classes positions don't work?

  - by SystemNetworks

  I have an external class which reads the user's mouse clicks. I gave a position where the user have to click, and when the user clicks on that position, it would turn my boolean "mouse" to true. But when I connect that to my game(state based) class, it does not work. Here's the code: External class public void UI(Input input, GameContainer gc, float posX, float posY) { int x = Mouse.getX(); int y = Mouse.getY(); if(posX<=100 && posY<=100) { if(Mouse.isButtonDown(1)) { mouse = true; } } } Game class(main) public void update(GameContainer gc, StateBasedGame sbg, int delta) throws SlickException { int x = Mouse.getX(); int y = Mouse.getY(); civ.UI(input, gc, x,y); } The problem is when I click my mouse at posX<=100 && posY<=100. It does not work.

• Somes importants shorcuts of Blender does not work on Ubuntu

  - by Linko

  In Ubuntu (and Mint) some important shortcuts for Blender does not work. Alt + right click to select an edge loop (heavily used on all 3D softwares) doesn't work, a useless menu of Ubuntu pop up to ask if the application must be closed or minimize. Ctrl + Alt + 0 to define the current view as the view of the camera minimize the application. This shortcut of Ubuntu is useless, it's faster to click on the minimize icon. Ctrl + number to apply a subdivision surface level do nothing on Blender, it's one of the most used shortcut of Blender. For the moment I stay on Windows 7 just to use these 3 shortcuts.

• Collaborative work (small team) - Best practices

  - by LEM01

  I'm currently working in a very small team of programmers (2-3) and I'm looking for advices/best practices on how to organise our work. We're all working on the same application using PHP. Today we're kind of all working on our way. Today situation: List item that have to be worked on by each dev 1/week. What has to be done is defined at a high functional level (ex: Build the search engine for this product..) Commit / merge our individual branches (git) every week before the next meeting No real dev rules, no code review No test written (aouutch) Problems faced: Code quality issue: discovering someone else code is sometime tough (inline, variable+function+class names, spaces, comments..) Changes in already existing classes (impact on someone else work) Responsibility of each dev unclear: after getting someone else code and discover something messy, should I make the change? Should he make the change? How to plan those things,... What I'm looking for: Basically I'm looking into structuring the way we develop things in order to avoid frustration and improve overall quality. How to define coding standards (naming convention, code rules...)? Do you you any validation script to make sure code is valid before committing? Do you think that defining an architect role in the team is needed? Someone that would actually define what has to be developed during the next phase. By defining interfaces or class descriptions that have to be written. (Does it make sense in such a small team?) Today we're losing time into understanding what others did or tried to do, we're also losing time in discussion like "you should have done it that way! Why is this class doing that and not that..? Shouldn't we have a embedded class rather that this set of data...". I'm looking into a work process, maybe with more defined responsibilities and process in order to improve our performance. If you have experience, advices, best practices or anything to share that we could benefit from it will be much appreciated! Thanks a lot for your time!

• Using gerrit (or similar tool) on a team where multiple devs work on a single feature

  - by Bacon

  We have a team of roughly ~8 devs who regularly work on the same feature over the course of a 3 week sprint. It isn't quite pair programming, but in our current workflow devs regularly push up incomplete code for a colleague to complete. This worked fine before we introduced Gerrit, but now our commits need to represent chunks of test-passing, complete, logical functionality, and so the model breaks. My only idea is to have everybody push up to a separate, untracked branch up until the functionality is ready for review, then squash everything into commits that make sense and push up. Is there another Gerrit-ized workflow that could work? I know this is a widely discussed topic on Google Groups, and that there has recently been some discussion of Gerrit topic reviews, but I wanted to see if there is anybody out there using Gerrit in this way, and what the suggested workflow would be.

• ctrl + a doesn't work in browsers

  - by protos87

  The combination for select all (ctrl+a) doesn't work in a browser (either if we speak about firefox or chromium). It doesn't work if I try to clik in to the adress bar nor if I try to use it to select what I've written in google search bar at google.com. When I press ctrl + a it simply takes the cursor before the first letter. This doesn't happen when I use a text editor software like Libre Office. There the shortcut does what's supposed to do, selecting all the text. What could be the problem?

• GitHub OS project how to have a good version and a work in progress version

  - by Para

  I have started my own OS application, I am hosting it on GitHub. My problem is that I push changes to the repository from more than one location so sometimes I want to work on it and sometimes I can't always finish something in time but I would still like to push it anyway so I can fetch it later from my other location. I'd like to be able to somehow have a stable version and have the master branch be a 'work in progress'. How do I do this? Is there some button I can push that will take the code from my master branch and make it into a zip file in my downloads tab and call it a version or should I do this by hand? Would it be better to have the master branch be nice and neat and have a separate branch to play with and then merge the two when the time is right? Would this not cause more problems in the merging phase?

• 12.10 nautilus on dell xps 12 does not work

  - by user108664

  I have installed 12.10 on a new Dell XPS 12 ultrabook. Everything seems to work properly right now, including the touch screen, except for nautilus. The left pane works properly, I can select an item on the left and the contents will show up on the right, but when I go to do anything with the contents on the right nothing happens, I can't double click to open, I can't right click to bring up a menu. I can however hold down the left button and to draw a box to select more than one item, but I can't do anything with the selected items. I did not have these problems when I tried 12.04, but unfortunately the touchscreen does not work out of the box on 12.04 and 12.10 seemed to be the faster way go. Any ideas? How can I log what is happening when I try to do anything in nautilus?

• Help my graphists sharing their work

  - by Andy M

  As a developer I'm used to Subversion for source control and I think it's great for sharing source code between developers. Now thinking about my graphists and game designers, they need to have a slightly different approach I think. They need to share binary files They need to be able to have a thumbnail and preview of their work I don't want to include their binaries into my game repository (would be much too heavy for developer when updating) I've seen that some graphists uses personally created website to share their work but I was wondering if some "standard" application existed in order to provide my graphists a cool way of working together. Is there a common way of dealing with this? Is the way I want to do (only final sprites on my game repo) correct? How do you guys do this as game developers?

I need to describe use-cases, perliminary definitions, example workflows of the application, goals, i/o of the application, requirements etc. Does someone have a sample doc. with "work packages" or a link to some corresponding resource in the net? Thx. PS. Initial term "(ger.) Arbeitspaket".

• Sudden Breakthroughs (Miracles at work)

  - by MobileDev123

  Lot of things has been discussed that can be taken as negative things about programmers work. Lets discuss about something good and unexpected things that happen to programmers. Example: (After R&D of two days and a lot of disappointments) You just spend an hour with your PM to explain that some feature due to some problem you are unable to release this module in today's beta... after a lot of arguments you are given an hour to make your app work without this module. You sit on your workstation to make a release and all of a sudden you find what turns out to be a silly little problem.... (you solve it and prepare a desired build) did you face miracle (= sudden, positive surprises?) in your life?? what was your reaction in case you have come through such experience?? (N.B. I know my English is not that good and that's why I'm open to every linguistic mistakes needed to be corrected)
