  • Git Daemon on linux?

    - by bwawok
    Trying to set up a simple git-daemon on a linux server, and talk to it from a windows box. On linux server: Make a folder /home/foo/bar CD to /home/foo/bar do a git --bare init here Do a touch git-daemon-export-ok CD to /home/foo Run the command git-daemon --verbose --reuseaddr --base-path=/home/foo --enable=receive-pack On Windows Client w tortoise Git Do git.exe clone --progress -v "git://servername/bar" "C:\source\myFolderName" (works) Create file a.txt, add it to git, and commit (works) Do a git.exe pull "origin" master and then get fatal: Couldn't find remote ref master (makes sense, master isn't there yet) Do a git.exe push "origin" master:master and tortoise hangs forever without do anything I realize why I can't pull from master yet on the remote branch.. but why can't I push my first commit into the remote repo? #4 really should work. Tried it both with tortoise and the mysysgit command line, both cases I hang forever. What am I missing? Server has no useful log

  • Postfix cleanup daemon access control

    - by Flimzy
    Is there any way to control which hosts are permitted to connect to the cleanup daemon over TCP? Our 'master.cf' contains: 2526 inet n - - - 0 cleanup This is necessary because we have a cluster of SMTP servers running custom code, and they can all inject mail to the centralized postfix server via the cleanup daemon. However, we want to allow only our authorized servers to connect to the cleanup daemon. The current configuration allows any host to connect to port 2526. Clearly we can use iptables to restrict access, but is there a way to do this within postfix itself?

  • How to Make the Gnome Panels in Ubuntu Totally Transparent

    - by The Geek
    We all love transparency, since it makes your desktop so beautiful and lovely—so today we’re going to show you how to apply transparency to the panels in your Ubuntu Gnome setup. It’s an easy process, and here’s how to do it. This article is the first part of a multi-part series on how to customize the Ubuntu desktop, written by How-To Geek reader and ubergeek, Omar Hafiz. Making the Gnome Panels Transparent Of course we all love transparency, It makes your desktop so beautiful and lovely. So you go for enabling transparency in your panels , you right click on your panel, choose properties, go to the Background tab and make your panel transparent. Easy right? But instead of getting a lovely transparent panel, you often get a cluttered, ugly panel like this: Fortunately it can be easily fixed, all we need to do is to edit the theme files. If your theme is one of those themes that came with Ubuntu like Ambiance then you’ll have to copy it from /usr/share/themes to your own .themes directory in your Home Folder. You can do so by typing the following command in the terminal cp /usr/share/themes/theme_name ~/.themes Note: don’t forget to substitute theme_name with the theme name you want to fix. But if your theme is one you downloaded then it is already in your .themes folder. Now open your file manager and navigate to your home folder then do to .themes folder. If you can’t see it then you probably have disabled the “View hidden files” option. Press Ctrl+H to enable it. Now in .themes you’ll find your previously copied theme folder there, enter it then go to gtk-2.0 folder. There you may find a file named “panel.rc”, which is a configuration file that tells your panel how it should look like. If you find it there then rename it to “panel.rc.bak”. If you don’t find don’t panic! There’s nothing wrong with your system, it’s just that your theme decided to put the panel configurations in the “gtkrc” file. Open this file with your favorite text editor and at the end of the file there is line that looks like this “include “apps/gnome-panel.rc””. Comment out this line by putting a hash mark # in front of it. Now it should look like this “# include “apps/gnome-panel.rc”” Save and exit the text editor. Now change your theme to any other one then switch back to the one you edited. Now your panel should look like this: Stay tuned for the second part in the series, where we’ll cover how to change the color and fonts on your panels.

  • Need help with creating complex UITableView items (like the Settings app).

    - by Craig
    I hoping to create a custom Settings view, similar to the Settings application, but with more control over the UI and access to some settings (i need to lock some of the settings). Obvously, there are a variety of UI elements mixed in each row of application's UITableView. For example, the 'Airplane Mode' setting shows a UISwitch, while the 'Wi-Fi' setting has a text value adjacent to the disclosure symbol (''). Further complicating matters, is the grouping of these settings. I have some general questions about the approach I should take: Seems like i need to save the name of the setting, its current value, its grouping, and the type of UI element(s) needed to modify its value. i would like to make use [NSUserDefault standardUserDefaults], but not have these settings appear in the Settings application. I'm guessing that I will need to create my own settings-persistence class. is it better to build each one of these complex UI-element combinations in code or to create a series of custom views based on the UITableViewCell and load the appropriate one? i'm guessing the latter. some of the setting require that i load another view to select its value. assuming that the application is based on the Utility pattern, should the SettingsView manage the navigation stack, rather than having the app delegate do so? Thanks for your time and comments. Craig Buchanan

  • How can I merge the gnome clipboard and the X selection?

    - by TREE
    I'm constantly frustrated by the two separate clipboards in X/Gnome. I'm constantly doing things like control-C to copy, and then middle-click to paste, and getting the wrong data. Or select something, then go where I want to paste it, and selecting what I want to paste over, only to lose my first selection! Is there any way to merge these two clipboards?

  • Is it possible to control the whole Gnome desktop with vi-like commands?

    - by roy
    I know with readline you can use emacs or vi commands to edit the input of several interactive text programs. I wonder if there exists such a similar facility to control the whole desktop in Gnome or in any other desktop environment. Maybe it could be a program that intercepts keystrokes and process them in the way vi does, translating sequences of characters to desktop commands and delivering to the active window only the text that is writen in insert mode. Do you know some tool like that?

  • How to change the X-Windows default border width for all window frames in Ubuntu using Gnome 2.28

    - by Heston T. Holtmann
    Way back from Windows 3.x days to the latest 64bit Windows 7 (classic/standard theme).. there is a way to make the window edge border wider then 1 pixel... I often use 3 to 5 pixel to make it easy to grab on hi-resolutions displays and hi DPI monitors. There doesn't seem to be an easy or obvious way to do this with the Gnome X-Windowing system? Does any one know how?

  • xmodmap reverting periodically

    - by JediBrooker
    I'm using xmodmap to swap control and command keys on my macbook pro. However, periodically the key revert back to their original state and this is becoming quite annoying. I'm on Ubuntu 13.10 and I can remember when this situation started occurring was when the system got a keyboard settings (in the system settings) update. Any ideas as to how to either: 1) delete the keyboard settings, or 2) stop the keyboard settings from reverting my keys ??? Cheers!

  • Install updates without breaking shell theme?

    - by Niko
    Recently I installed a copy of Oneiric Ocelot 11.10 on my ThinkPad. Everything went fine, I installed the gnome shell and gnome-tweak-tool to customize everything. I changed the shell theme, the GTK+ theme and the icon set. After everything fit my needs perfectly, I installed some updates from the update manager (no upgrades, just small updates). I had to restart, and after I restarted, my gnome shell was broken. In tweak-tool, it showed the customized shell as the default one, and my gtk theme was broken as well (it looked like two themes "frankensteined" together...). The bad thing was - I couldn't get things back into the default settings! So the only thing left was to use the -non broken- unity shell. What can I do to stop these things from happening? (I mean...sure I could avoid the updates, but that would be kind of stupid, too.) I only have these PPAs installed: ferramroberto-gnome3-oneiric.list (and .save), playonlinux.list (and .save) And how can I fix the broken gnome-shell?

  • Raleigh theme on LightDM, Ubuntu desktop, Nautilus window, menus & menu-bars

    - by Tassos Seligkas
    After performing an upgrade from Natty to Oneiric, I had a problem similar to the one reported in here at every system boot: Desktop forgets theme? Everything, from the LigthDM greeter to the ubuntu desktop used the ugly raleigh theme, apart from firefox, thunderbird few other applications after logging in. Unfortunately none of the solutions suggested in the topic above worked for me. The only way I could get acceptable appearance would be to switch to gnome at login and using the Adwaita theme. The lightdm greeter still uses the raleigh theme though. Unfortunately, I tried some "brute-force" methods by reinstalling (sudo apt-get install --reinstall) ubuntu-desktop, unity, unity-common, unity-greeter, gnome-session, gtk2-engines. I also tried moving .config, .gconf, .gconfd, .gnome, .gnome2 to a backup dir to reset account desktop preferences. None of the above solved the issue. On the contrary, logging-in to Ubuntu setup does not show unity and window decorations anymore. My fallback remains the Gnome logon and the Adwaita theme. This is my workstation machine I am hosting Ubuntu on, so, though possible, it is time consuming to perform a backup and format-reinstall ubuntu 11.10. Could you please let me know if I can get an alternative way of repairing my ubuntu desktop? (I believe it all started when, during the 11.04-to-11.10 upgrade, the installation of downloaded packages for oneiric broke when nautilus-dropbox failed to access the dropbox servers - I am behind a proxy but with proper proxy settings had no problems using apt-get & synaptic. However I removed dropbox and resumed partial installation on second boot.)

  • Help, broken Gsettings

    - by Rene
    I was trying to disable the global menu as per http://ubuntuhandbook.org/index.php/2013/07/disable-global-menu-on-ubuntu-13-10-saucy/#comment-8612, but while it didn't change anything, after running the autoremove command unity-tweak-tool broke. Obviously my first reaction was to re-install the removed package but it remains broken. TBH I don't know if it is even related or just a coincidence. When I start it from the launcher it just blinks and disappear. When I start it from terminal I get this error: $ gnome-tweak-tool WARNING : Shell not installed or running WARNING : Error detecting shell Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/gtweak/tweaks/tweak_shell_extensions.py", line 199, in __init__ raise Exception("Shell not running or DBus service not available") Exception: Shell not running or DBus service not available INFO : GSettings missing key org.gnome.nautilus.desktop (key computer-icon-visible) WARNING : Shell not running None INFO : GSettings missing key org.gnome.mutter (key workspaces-only-on-primary) Segmentation fault (core dumped) I had a look with dconf-editor if I could just add the missing key, but apparently keys aren't meant to be added "by hand". So how can I fix this? I'd rather prefer not having to reinstall everything. Which package is broken, can I just reinstall that? EDIT: I found by being root gnome-tweak-tool no longer crashed so possibly a permission issue somewhere. I don't know that I changed any permissions. Another related problem, actually the reason I noticed the problem at all, is that unity-tweak-tool seem no longer to want to save the values edited. I normally just have the Unity launcher on the primary display but wanted to check what it was like having it on both. I didn't like it so I went into unity-tweak-tool to set it back - but regardless how many time I tick "only primary display" it never changes anything. What does the Unity-tweak-tool actually change and can I do this directly somehow?

  • How to make pulseaudio and ubuntu detect the same audio device as alsa driver

    - by Kiwy
    I use Ubuntu 14.04 x64 and I use gnome-shell on my laptop. I have a Bose companion 5 (which is basically a USB sound system) and a HDMI port, both does work perfectly when I just boot with the cable plugin. However, when my laptop go to sleep or get unplugged from those two outputs, if I plug back the device, I end up without any hardware detection (only the built-in speakers) from pulse and gnome-shell sound output selector while if I use alsamixer, the device look up and ready. gstreamer-properties allow me to select and test effectively any device but while alsa recognize any device on the run, pulse is not capable of handling things correctly, my question is then: How can I make pulse detect and use the same hardware as alsa, or how to remove completely and gracefully pulseaudio (meaning volume applet running in gnome shell) I don't mind if the project implies to recompile half gnome shell if it implies those audio outputs work all the time. Pulse does not list my soundcard when I use command pactl list cards while the module plug&play for sound card is loaded in pactl list modules. I really don't know what to do, the behavior seems pretty random.

  • Missing launcher after 12.04 upgrade

    - by Preston Zacharias
    I recently upgraded to ubuntu 12.04 and after doing some updates and such my application launcher and title bars (for window dialogues) are missing. Basically the entire unity GUI is missing! Not sure what happened so I installed gnome 3 and it was missing a launcher too, but did have title bars. In addition the bar found at the top that lets you know what's open and allows gnome extensions to be displayed is not interactive. I can't click, right click, alt + click (right or left), alt + super click (right or left) anywhere! I even installed an application menu from the gnome site and it is not interactive either. However, since there is no way to launch applications i have to use terminal and if i minimize an app it will disappear completely. Then i decided to try unity 2D and it is incredibly messed up. Black background, launcher is there but icons and top bar while on desktop are completely distorted. They're not just pixalated; they're all sorts of funky colors and when i open something from unity 2d launcher it will show it's opened in the launcher but nothing appears on my screen. When trying to view videos on youtube the video is distorted and looks just as unity 2d does. Strange enough: the audio works fine, just not videos. Pictures loads, but not ads that stream video. Any suggestions to get my launcher and the unity GUI back? I tried reinstalling gnome, unity 3d, and unity 2d from terminal. no change. also reinstalled unity desktop and tried resetting it: nothing happened.

  • Trying to write up a C daemon, but don't know enough C to continue

    - by JamesM-SiteGen
    Okay, so I want this daemon to run in the background with little to no interaction. I plan to have it work with Apache, lighttpd, etc to send the session & request information to allow C to generate a website from an object DB, saving will have to be an option so, you can start the daemon with an existing DB but will not save to it unless you login to the admin area and enable, and restart the daemon. Summary of the daemon: Load a database from file. Have a function to restart the daemon. Allow Apache, lighttpd, etc to get necessary data about the request and session. A varible to allow the database to be saved to the file, otherwise it will only be stored in ram. If it is set to save back to the file, then only have neccessary data in ram. Use sql-light for the database file. Build a webpage from some template files. $(myVar) for getting variables. Get templates from a directory. ./templates/01-test/{index.html,template.css,template.js} Live version of the code and more information: http://typewith.me/YbGB1h1g1p Also I am working on a website CMS in php, but I am tring to switch to C as it is faster than php. ( php is quite fast, but the fact that making a few mySQL requests for every webpage is quite unefficent and I'm sure that it can be far better, so an object that we can recall data from in C would have to be faster ) P.S I am using Arch-Linux not MS-Windows, with the package group base-devel for the common developer tools such as make and makepgk. Edit: Oupps, forgot the question ;) Okay, so the question is, how can I turn this basic C daemon into a base to what I am attempting to do here?

  • How to access MyProject.MySettings.Default.SomeSetting from xaml?

    - by Shimmy
    I have defined a StringCollection in the Project Settings. I want to use the values in a ComboBox. Is there a way to access it xamly? I tried: <CollectionViewSource Source="{x:Static src:MySettings.Default.MyCollection}" /> <CollectionViewSource x:Key="RoomSections" Source="{x:Static src:MySettings.Default.RoomSections}" /> *src is the xmlns of the project It says: "Type src:MySettings.Default was not found". The thing is that MySettings is a class that offers a Default property which is a thread-safe instance of MySettings, I really want to get the collection from the Default property and not by instantiating a new on. Is there other ways I am not aware of, maybe ObjectDataProvider can access static objects? I thought, maybe I can make in the App.xaml a global resource that return MySettings.Default which is an instance of the MySettings class, and then access all its properties, I will try that out, but I prefer the easy way.

  • Trying to setup a PHP daemon using System_Daemon and I'm having issues getting it to run.

  • Is it good to use .settings for storing controls text data?

    - by Zenya
    In my WinForms applications I often put the controls text data (form title, labels texts, button captions, etc.) into a .settings (feature automatically generated by Visual Studio - based on the ApplicationSettingsBase class). In particular, Add a form or a control. In Solution Explorer add a new string item into the application scope of the settings file. Bind the control text property with the corresponding item of the settings file (through the property binding). Good point of this is that all my text data is collected in one place and easy to check and edit. Also it is convenient when I want to use the same text for several controls. However, I haven't heard that somebody uses the .settings such way. In tutorials for creating multilingual applications, for example, it is recommended to enter texts directly into the control property. So, is it good practice to use .settings for storing controls text data? Brief conclusion from the answers: Storing controls text data in the .settings is not common practice.

  • XNA/C# Game Settings (Menu?)

    - by PCAddict
    It's my first time trying to make anything really interesting in C# and I was trying to make a simple form or game screen where the user could define a custom resolution/screen ratio etc. or to automatically detect the max screen size/ratio and output? its my first game, so I was wondering if it was possible or if there would be any major issues with such, rather than just setting it to 1366x768 (the resolution of all of my computers). Thanks in advance for any assistance.

  • ASP.NET plug-in architecture, settings problem

    - by Xaqron
    I want to divide business layer (BLL) of an asp.net application into multiple components. Each component is a .NET class library which is compiled as a standalone DLL. These components should have their own configuration files. For example "MyNameSpace.Users.dll" contains classes about users of the website and there's a password policy to check if password length is at least x characters. When webmaster edits the config file of this DLL and set x to y then component (DLL) should use new value (y) in the future and enforce passwords to be at least y characters. I want each component as a single project and compile them separaely (and not to put all projects in a solution in Visual Studio), and put the DLLs of these libraries into the "Bin" folder of my ASP.NET application. Is it possible ? Where should I put these config files ?
