  • ATI graphics card, with gnome shell on Ubuntu 11.10, screen flickers

    - by bioShark
    After installing gnome shell, without any problem, after log in the fonts are missing and it looks like crap...nothing is readable. Don't want to make it a double post, because my issue is similar to the one from this question but for me the problems have not been solved properly. After running the commands from that post, and installing the latest AMD 11.10 driver, the Gnome shell display issues have been solved. But each time I move the mouse in the upper left corner, to bring up the applications...my entire screen flickers. Without the applications been displayed, everything looks fine. Hardware: ATI HD4870, Intel Q6600.

  • Ubuntu 11.10 Gnome Shell new window focus problem

    - by grafthez
    I'm using gnome shell with new ubuntu for few days now and have experienced really annoying behaviour with new windows. Sometimes when I use another window and press e.g. Alt Ctrl T to open new terminal window, I don't get this window being brought to front. Instead I get notification at the bottom that "New terminal window is ready to use". The same is with Pidgin being integrated with gnome shell (via extension). Every time I get new message, window pops up but doesn't show. I need to either Alt Tab it or click the notification. Is there any way to have new windows being always brought to front, and remove those annoying "Window is ready" notifications?

  • Only close button shows up in Google Chrome in GNOME Shell

    - by TreefrogInc
    After I installed the GNOME shell in Ubuntu, I decided that I didn't like having the "Close/Minimize/Maximize" buttons on the right, so I switched them over to the left using gconftool-2 --set "/apps/metacity/general/button_layout" --type string "close, minimize, maximize:" After resetting the shell, however, I found that with the GTK+ theme, only the close button shows up. Using system title bar and borders will make all the buttons appear, but I really want to use the theme because the system title bar makes the top bar too thick. Logging out and back in didn't fix it, and I tried reinstalling Chrome, but the problem persists.

  • What's shell script's advantage over interpreted programming languages?

    - by Lai Yu-Hsuan
    (I'm not sure if it's a appropriate question here) Shell script, like bash, can do many things. It can call Unix programs, pipe their output, redirect I/O from/to files, control flow, check whether a file exists, etc. But a modern programming language, e.g, python and ruby, can also do these all. And their are (I think) more readable and maintainable. bash is worldwide spreaded. But many distributions have installed python interpreter, too. So what's the advantage of shell script? If I could write python, ruby or perl, is it worth to learn bash?

  • New windows from the dock in Gnome Shell

    - by Andrea
    I am using Gnome Shell on Ubuntu 11.10, and I frequently use workspaces, as the shell encourages to do. My only complaint is that it is slow to place different windows of the same program in different workspaces. What I would like to do: click on an empty workspace, click on the Nautilus icon in the dock and browse to the correct folder. Then click on another empty workspace, click on the Nautilus icon and so on. This does not work: the second time I open Nautilus, the dock lets me switch to the previous instance, which is almost never what I want. So I have to click on the Nautilus icon, open a new window, place it on a different desktop, switch to that folder and finally browse to the correct folder. Is there a way to simplify this flow? It would be even better if I was able to link a specific folder from the dock, or better yet to have something similar to a Unity lens, where I can choose between the most used folders.

  • How to disable Gnome-Shell auto-open in Dashboard

    - by user48027
    I am personalising my Gnome-Shell in Ubuntu 11.10 I would like to disable the feature to open the Gnome's Dashboard when I close the last Window in a Workspace. Edit to clarify: The dashboard is available only in GNOME Shell. The dashboard opens if you press the windows key (aka SUPER) or if you move the mouse to the upper left corner. If you close the last window of a workspace, but there are open windows on other workspaces, the dashboard opens automatically. The latter behaviour is annoying if you do not want to use the dashboard to open new windows or to change workspace. There are many ways to to both (Gnome do, Docky, keyboard shortcuts, clicking on something on the desktop, ...). Edit: There is a related Q&A, which was closed because the asked the same question for Mint: How can I prevent the activity view for opening when I close the last running app?

  • Writing a basic C Shell - understanding argv[] [on hold]

    - by Flame
    I have an assignment for my class to write a basic C Shell. I have found many pages that explain parts of it and some fully implemented code. I'm not going to copy, i'm just using it right now as a way to get started. So I'm at the beginning of this project obviously. One example I am looking at parses the user's input and stores a pointer to the beginning of the argument in char *argv[3]; Am I just misunderstanding this or would this technically break if there are more than 3 arguments? (say /a.out arg1 arg2 arg3 etc). Would I wanna malloc this somehow? I know a.out is considered argv[0], and the arguments argv1 - however many there are. It's probably bad practice to have too many arguments for a program, but I still would at least want to address it as I don't know what my TA's are going to use to test my shell.

  • Is there a way to prevent output from backgrounded tasks from covering the command line in a shell?

    - by Chris Pick
    I would like to be able to run task(s) in the background of a shell and not have their output to stdout or stderr cover the command line at the bottom. Frequently I need to run other commands to interact with the background processes and would like to do so from the same shell without having to open up another terminal or using multiplexer to split the terminal like screen. Ideally there would be some setting that I just don't know about (I commonly use bash or ksh), but a new or different shell or a script would be fine by me. I'm open to any suggestions and appreciate any help, thanks.

  • Erlang-style light-weight processes in .NET

    - by alexey
    Is there any way to implement Erlang-style light-weight processes in .NET? I found some projects that implement Erlang messaging model (actors model). For example, Axum. But I found nothing about light-weight processes implementation. I mean multiple processes that run in a context of a single OS-thread or OS-process.

  • Node.js or Erlang

    - by gotts
    I really like these tools when it comes to the concurrency level it can handle. Erlang looks like much more stable solution but requires much more learning and a lot of diving into functional language paradigm. And it looks like Erlang makes it much better when it comes to multi cores CPUs(fix me if I'm wrong). But which should I choose? Which one is better in the short/long term perspective?

  • Code hot swapping in Erlang

    - by Roger Alsing
    I recently saw a video about Erlang on InfoQ, In that video one of the creators presented how to replace the behavior of a message loop. He was simply sending a message containing a lambda of the new version of the message loop code, which then was invoked instead of calling the old loop again. Is that code hot swapping in Erlang reffers to? Or is that some other more native feature?

  • What is Erlang's concurrency model actually ?

    - by arun_suresh
    I was reading a paper recently Why Events are Bad. The paper is a comparative study of Event based and thread based highly concurrent servers and finally concludes stating that Threads are better than events in that scenario. I find that I am not able to classify what sort of concurrency model erlang exposes. Erlang provides Light Weight Processes, but those processes are suspended most of the time until it has received some event/message of some sort. /Arun

  • Should I consider Erlang for web mvc?

    - by gotts
    Can I do that? I'm afraid that this can be an overkill and eventually I'll end up with much less productivity than with traditional stack like Ruby/Python/you name it. I understand that you will start with much lower productivity if you start to work with new technology but .. is it potentially worth trying and finally switch to Erlang as the only tool for web development and all the backend stuff. Or is Erlang more suitable for only some high performance backend tasks?

  • Adding nodes dynamically and global_groups in Erlang

    - by ZeissS
    Erlang support to partition its nodes into groups using the global_group module. Further, Erlang supports adding nodes on the fly to the node-network. Are these two features usable with each other? As far as I understand, you have to name every node on startup to use the global groups.

  • Find maximum positive integer value in Bourne Shell

    - by l0b0
    I'm checking a counter in a loop to determine if it's larger than some maximum, if specified in an optional parameter. Since it's optional, I can either default the maximum to a special value or to the maximum possible integer. The first option would require an extra check at each iteration, so I'd like to instead find out what is the maximum integer that will work with the -gt Bourne Shell operation.

  • How to delay putting process in background until after it is ready to serve, in shell

    - by Jakub Narebski
    I have two processes: a server that should be run in background, but starts serving requests after a delay, and a client that should be started when server is ready. The server prints line containg "Acceptin connections" to its stderr when ready (server stderr is redirected to a file when running it in background). How to delay putting server process in background until server is ready to serve requests? Alternatively, how to delay running client until server is ready? Language: shell script (or optionally Perl).
