• How important is using the same language for client and server?

  - by Makita

  I have been evaluating architecture solutions for a mobile project that will have a web-service/app in addition to native apps and have been looking at various libraries, frameworks, and stacks like Meteor, this being a sort of "open stack package framework", is tightly bound with Node.js. There is a lot of talk about the benefits of using the same language both client and server side, and I'm not getting it. I could understand if you want to mirror the entire state of a web application on both client and server but struggling to find other wins... Workflow efficiency? I'm trying to understand why client/server language parity is considered to be a holy grail. Why does client/server language parity matter in software development?

• How can I restart compiz from tty? (& Related, how can I set up a fallback WM?)

  - by Jon

  So I'm testing Natty, and Compiz keeps crashing on me. I expect this sort of thing from alpha software, of course, but it doesn't always give me the option to restart compiz, and for some reason doesn't have a fallback WM configured. Without a window manager, all my programs are still running, but they're not accepting input from the keyboard, and I can't switch between them. I can, however, press Ctrl+Alt+F1 and get a terminal, and I can killall Xorg to reset everything, but I'd rather just reset compiz if possible. If I try typing compiz --replace there in the tty, it complains "fatal--couldn't open display." Is there a way to have tty1 restart compiz? Like compiz --replace --display=something? Additionally, is there a way to configure a fallback window manager so that there's an easier way to recover from compiz crashing?

• Unity launcher full - Need more icons

  - by Martin Wildam

  I have already reduced the Unity launcher icons to 32 but still the space is exhausted already with my most-used programs. Basically I have to scroll often in the unity launcher bar with is annoying. So far (Ubuntu 10.04) I had those icons as mini ones in the top panel (smaller icons and wider space) where they could fit all. I was thinking already of sub-launchers or something the like but could not find something like the drawer was in Gnome 2. I am using Ubuntu at home and in the office. I am a consultant and need a lot of stuff on a regular basis. To put links at the desktop does not make sense because of the many windows that I usually have open there is hardly ever a piece of the desktop looking through. How do you - power users get keep most-used programs at reach (and I mean <= 2 clicks away)?

• How can I backup files on /etc using Deja Dup? [closed]

  - by Chris Good

  Possible Duplicate: How do I open Deja Dup as root? I am using Ubuntu 12.04 LTS. I'm trying to setup Deja Dup to backup the files for several users (/home) and /etc but as it runs as myself, there are many files it cannot read and therefore cannot backup. I want to try running Deja Dup as root as then it should be able to read and backup all files. I've seen some other info about how to set up a particular App to run as root, so I guess I should try that.

  Xamarin abandonne Moonlight la version Mono de Silverlight, la plateforme a-t-elle encore un avenir ? Microsoft supportera la version 5 de Silverlight jusqu'en 2021, et pourrait même développer une version 6.

• Debugging OpenOffice crashes

  - by JD Long

  This is partly an OpenOffice question and partly a Ubuntu question. I'm running OpenOffice 3.2.0 and Ubuntu 10.04. I get frequent crashes of OO, especially the Calc app, although I get crashes in the word processor as well. They are very abrupt and accompanies by no warning or error message. I'm just typing away and then the app is gone. Sometimes I even end up thinking I'm typing in OO and discover that OO has crashed and I'm typing in whatever application was under OO. However, I can't reproduce these crashes on demand. They seem random. I can open the same file and do the same exact thing but it does not crash. In Ubuntu how do I trace, track, or diagnose these types of crashes? Is there software I can invoke to help diagnose? Can I start OO from a command prompt with debugging of some sort enabled? Note: if someone could add the tag OpenOffice, I would appreciate it

• Where can I find a package for "project looking Glass"? ("The Java desktop")

  - by Alvar

  Hi, I really really want to find this package. Because after I saw the youtube clip I realized it's just one of those things I must have done before I die. This tutorial would be great if the repository were online. My question is: Where can I find the file, and how can I install it without changing my current desktop? The project was called "project looking glass" and was released in 2007. It is now an "inactive open source project", according to its Wikipedia article. @Takkat found this VERY good live cd, hope it works.

• photshop: why low quality jpg saved as high quality increases the file size?

  - by Alex Angelico

  i have a low quality background about 85kb. If I open the file in Photoshop and save it, I have to save this image as 100% quality, the file size increases to 640kb. This doesn't make sense, the image si already compressed, the quality cannot be better than the source, so the 100% quality while saving should produce THE SAME FILE OPENED. The problem is, I have this background and want to add a logo image over it, and then save it. But If I do so, i have to save this with 10% quality, and the logo looks horrible. If I save this to 100% quality, the file size is huge... How can I achive this?

• 12.04 - why does the network icon dissapear every time my machine is turned off

  - by Howard Walker

  After spending an hour or two working out how to find the network Icon, I find that when I reboot the machine, I have to go through the whole procedure again. 1. The network menu is not there - so first I have to find the terminal. This has no particular location that I can find but usually I have to type terminal in the dash. 2. Then I have to type nm-applet in terminal 3. The network manager icon then appears, but only works if the terminal window remains open. Shut down the terminal window and the network disappears. This is a pain - plus I have to type my password in every time, which is another waste of time, thought this has always been a problem. So can anyone tell me how to make the web automatically connect at startup without any intervention from me.

• Benefits of using the same language for client and server?

  I'm looking at architecture solutions for a mobile project that will have a web-service/app in addition to native apps. I've been looking at various libraries, frameworks, and stacks like jqm, backbone, parse, and meteor. Meteor, sort of an "open stack package framework", is tightly bound with node.js.

• Joomla Backend running slow on localhost

  - by boothe

  I made a local backup of a Joomla site a few months ago to test changes before updating the live site. Everything worked fine. Today I checked the local version after a while but when I open the backend (/administrator) it takes a while until the site is loaded. I tried out different things and accidently disconnected my Network Connection. After that everything loads as fast as before. But when I connect the Network Connection the problem reappears. I am running Joomla 1.5.14 on XAMPP 1.7.0.

• Bug Tracking Etiquete - Necromany or Duplicate?

  - by Shauna

  I came across a really old (2+ years) feature request issue in a bug tracker for an open source project that was marked as "resolved (won't fix)" due to the lack of tools required to make the requested enhancement, but since the determination was made, new tools have been developed that would allow it to be resolved, and I'd like to bring that to the attention of the community for that application. However, I'm not sure as to what the generally accepted etiquette is for bug tracking in cases like this. Obviously, if the system explicitly states to not duplicate and will actively mark new items as duplicates (much in the way the SE sites do), then the answer would be to follow what the system says. But what about when the system doesn't explicitly say that, or a new user can't easily find a place that says with the system's preference is? Is it generally considered better to err on the side of duplication or necromancy? Does this differ depending on whether it's a bug or a feature request?

• How to fix missing menus in non ubuntu maverick apps

  - by piedro

  Hi! There's a bug with the menue of filezilla: When opening filezilla there is no menue list. Very inconvenient because you can't open the "settings"-dialog. There are several workarounds that I tried - none of them really work. change theme while filezilla is running, menue reapperars. Once you close and reopen it the menue is gone again. add "export UBUNTU_MENUPROXY=0" " to .bash.rc or just call it before starting filezilla. Doesn't have any effect for me - menue still missing. tried "sudo apt-get remove appmenu-gtk" cause it's obviously to do with unity but the funny thing is even this method has bo effect at all! How can I fix this? How to do the troubleshooting? thx fior reading, p.

• pgadmin III doesn't work due to "The server lacks instrumentation functions."

  - by Chaz SLiger

  When pgAdmin III is used to open a PostgreSQL database the following message appears. There does not seem to be any obvious package listed in the Ubuntu Software Center for this. The server lacks instrumentation functions. pgadmin III uses some support functions that are not available by default in all PostgreSQL versions. These enable some tasks that make life easier when dealing with log files and configuration files. The adminpack is installed and activated by default if you are running the one-click installer of PostgreSQL. On Unix, you may have to install the contrib package, either with your package installer tool or by compilation.
