• QMake et au-delà : le futur de l'outil de compilation de Qt, un article de Marius traduit par Louis

  Bonjour, QMake est un outil qui simplifie grandement le processus de compilation pour de différentes plateformes. Son prédécesseur était un script Perl nommé TMake, qui, dépassé, avait vite été remplacé par le QMake que nous connaissons. Aujourd'hui, ce dernier semble à son tour ne plus apporter une réponse au besoin initial, étant devenu difficile à maintenir. Ainsi, devant la diversité et le nombre des avis internes, Marius a décidé de rédiger un article dans les Qt Labs Blogs afin de demander aux développeurs aguerris leur avis sur la question. Qu'allons-nous faire de QMake ? C'est la question, posée par Marius en début...

• Scripting for a C#, multiplayer game

  - by Vaughan Hilts

  I have a multiplayer game written in C# and we've recently been creating a lot of content but have been looking for a way to give our entities customization logic that the designers can hook into. I took a look at this post. With something like this in mind (using C# as a scripting language); I have a few questions. 1) Would one embed the script itself in the entity object before persisting to it to the disk? Is this okay? 2) Would I compile once per scripting then - this seems like a lot of overhead to store all these compiled Assemblies to execute. Any general advice on how to do thigns is welcome, too. These entities are generated on the fly inside the editor and could be composed of a lot of different things.

• Ubuntu One Windows Client 3.0.1 - Sync not connecting

  - by Tweezak

  I've got sync working at home on Natty and I need to access files at work. I've just installed client 3.0.1 at work on Windows 7. It's finding my account and sees what devices are already set up for sync but it just repeatedly tries to sync (File sync starting...) and after a while fails (File Sync is disconnected.). This cycle loops endlessly. I'm suspicious that it's a problem with my proxy setup. My employer doesn't use a manual proxy configuration but instead uses an automatic configuration script at a specific http address. Does U1 recognize that kind of setup or is it only looking for a proxy server in the form of an address/port?

• Simultaneous Animation for a GameObject - Unity3D

  - by Fahim Ali Zain

  Its my second week with Unity. I am doing a 2D game and I have a small GameObject which should change its sprite along with following a definite path defined in Animation Curves. I did both of them in separate .anim files since the transform animation had many keyframes, i thought it wont be good to put the '2' sprite keyframe repeatedly along side the transform keyframe. But the problem is, I cant get it both working together at the same time. I dont want any blending because the animation is timed well already. Also, I tried deleting the sprite change animation and tried it under script changing the SpriteRenderer.Sprite property under Update(); but it works only when the Animator component is disabled in the GameObject. Any Solutions ? :)

• Why doesn't apache2 respect my envvars file?

  - by Avery Chan

  My envvar files has these lines in it: export APACHE_RUN_USER=www-data export APACHE_RUN_GROUP=www-data My apache2.conf has these lines in it: # These need to be set in /etc/apache2/envvars User ${APACHE_RUN_USER} Group ${APACHE_RUN_GROUP} But when I run apache2 -M I get this: apache2: bad user name ${APACHE_RUN_USER} A temporary fix is to hard-code www-data into it my apache2.conf file. There was some speculation here that this was because some configuration script didn't replace the env vars correctly in my apache2.conf file. Regardless how do I get apache2 to consult my envvars file? As another data point this site seems to indicate the envvars is generated at build, but read by apache2ctl at runtime, suggesting that this file isn't just poop leftover by the build process.

• How to make sudo remember my password and how to add an application to startup

  - by Bragboy

  I guess this should be a simple thing for ubuntu users out there. I have two questions. Whenever I need to run some command that requires permission from root, I run as sudo followed by that command. It would be nice if that does not prompt for password (but I should still be issuing a sudo to make sure that I know what I am doing). How to do this? Every time I start my system, I go to terminal and start my VPN using sudo vpnc. This is almost everytime! How to automate this to a startup script? Help much appreciated! Thanks

• Font gets enlarged when rotating screen

• Installation automation

  - by Denis Gorbachev

  Use case: When I install Ubuntu on another computer, I need to: install all the packages that I use; make some config changes; svn checkout some projects; git clone some projects; setup .ssh/config; download a custom Eclipse build; download some additional Eclipse plugins; make many other tweaks. So, I want to run a script, like sudo install-everything-needed, that would execute these predefined actions. Is there any package that provides the backbone for such system?

• Dual Partion windows not working ?

  - by Jason Wagner

  I originally set up Ubuntu "along side" widows(Vista) and realized it was done though wubi after I tried to set up a VB and didn't have enough room. I then repartitioned the HD and did a stand alone Ubuntu install. The problem is when I try to boot windows it starts to load then does a flash and heads back to the start up boot page with ubuntu and windows on the boot screen. Ubuntu loads fine, everytime but windows goes back. Here is the boot script info. http://paste.ubuntu.com/6405545/ Any help would be appreciated. I want to leave windows behind but still need it for some things on this machine.

• How to keep "dot files" under version control?

  - by andrewsomething

  Etckeeper is a great tool for keeping track of changes to your configuration files in /etc A few key things about it really stand out. It can be used with a wide variety of VCSs: git, mercurial, darcs, or bzr. It also does auto commits daily and whenever you install, remove or upgrade package. It also keeps track of file permissions and user/group ownership metadata. I would also like to keep my "dot files" in my home directory under version control as well, preferably bazaar. Does anyone know if a tool like etckeeper exists for this purpose? Worst case, I imagine that a simple cron job running bzr add && bzr ci once or twice a day along with adding ~/Documents, ~/Music, ect to the .bzrignore Anyone already doing something similar with a script? While I'd prefer bazaar, other options might be interesting.

• lock screen before hibernating [12.04]

  - by Emanuel Ey

  So when i hibernate my laptop the screen doesn't lock automatically. To solve this if changed /etc/acpi/powerbtn.sh to contain: su - myUsername -c "gnome-screensaver-command -l" sudo pm-hibernate exit 0 When running this file from a command line it works as intended (ie, lock the screen and then hibernate). Unfortunately, when pressing the power button, it still just hibernates without locking the screen -what am I missing? EDIT: I've added the line whoami>>~/Desktop/test.txt to verify which user is executing the /etc/acpi/powerbtn.shscript. When pressing the power button, the file test.txt is created, but is empty. From this i conclude that the script is in fact being called when pressing the power button. What i do not understand is how the output of whoami can be empty...

• How to opendns with dynamic ip

  - by Joshua Robison

  OpenDNS is almost completely useless with a dynamic ip and most people have dynamic ip addresses. There isn't even a decent client for Linux to update your IP. There is a script you can install but it only seems to update on startup and all my child needs to do is unplug and replug the cable from the wall or router and a new ip is created totally killing the opendns service . I'm not even sure the Mac or windows ip update clients can protect from such a simple maneuver . How can I get my ip address to constantly update with opendns, is my question.

• Network Manager Applet menu freezes and does not respond

  - by pst007x

  Since the latest update in Ubuntu 10.10, the nm-applet has started doing some strange things. I boot up the PC, all is fine, internet works, etc... but after a period of time, approx and hour, the nm-applet menu in the Gnome panel fails to respond. when I click on the icon, the menu appears, all looks well, but when I select any option, eg DISCONNECT, nothing happens. Even the VPN sub menu disappears (no triangle to select the menu.) However I do not lose the network connection... If I Run this script: killall nm-applet /etc/init.d/NetworkManager restart nm-applet all returns as normal, for a while... weird? i tried uninstall/reinstall... I even reinstalled Ubuntu, but once the latest updates are applied this issues arises... Any help?

• In NetworkManager, my nm-dispatcher is never called.

  - by Alain Pannetier

  I've got two Ubuntu laptops (both 10.10). One is a new Maverick install and the other has been upgraded many times since 9.04. On the latter, setting up a custom script hook in /etc/NetworkManager/dispatcher.d/ worked instantaneously. However, on the older laptop, I can't get nm-dispatcher to get called, or at least to execute its hooks. I've tried to run NetworkManager --no-daemon -log-level=DEBUG But there is no mention of nm-dispatcher. How can I Have a look at the source (I looked into the git repo but could not find anything. find why the nm-dispatcher never gets called.

• AutoSSH for a robust tunnel

  - by Budric

  I'm trying to start an ssh tunnel from A to B and have it run despite things like: period network/wifi drops on A and remote server reboot on B. My ssh tunnel starts using upstart script on A with event start on (net-device-up IFACE=eth0) I've found autossh which is supposed to handle these kinds of things, but had some trouble getting it to work. The upstart executes: autossh -M 0 -2qTN -o "ServerAliveInterval 30" -o "ServerAliveCountMax 2" -L 5678:somehost:5678 user@B However when I log into B and kill -9 that tunnel session, autossh just exits with "Connection to B closed by remote host." That's not what I expected autossh to do. Any advice on how to set this up? Any GUI service monitoring utilities out there that essentially display a green light if a service is up? Thanks.

• How to import .m3u playlist

  I exported my my iTunes playlists to .m3u files before I got rid of Win7 completely. Now I would like to import the playlists into Rhythmbox, but can't. My playlists contain windows filenames (e.g. D:\music....) instead of linux filenames (e.g. /mnt/music....). The music is still stored on the exact same disk and folder as it was under windows. I need a script to convert the file names, can anyone help?

• Getting bank account information from a bank and displaying on a website [closed]

  - by Ali Syed

  Hello I am looking for a way to get bank account information (transactions and balance) from a financial institution and display it on a website. The question is vague intentionally.... Everything is open. I haven't chosen a bank, serverside technology or front end technology. The idea is to have a script run automatically periodically (once or twice a day) and get the latest account information from the bank server automatically. Probably something in the direction of OFX (Open financial exchange), HBCI (home banking c.. interface), fnts or something like it. Even working over a closed source API is not out of question: Wesabe or Mint or something. Paypal is not an option because it won't work in India or Pakistan. cheers *Explanation: I have an exclusive small club. My members make irregular payments. These transactions should be online for all MEMBERS (with login) to see *
