  • Unity bar only shown in Desktop - Alt+Tab doesn't show anything

    - by Christian Vielma
    I've experienced something weird with Unity and that is that sometimes the Alt+Tab switcher stops showing (yes, only showing because I can still to blind switch between applications), and the left unity bar is only shown on the desktop. I might think that it's compiz, but the rest of the effects are ok :S I don't have the exact sequence to repeat this error, it seems to be random :S Do you know what could it be?

  • What is wiser for me? Eclipse or IntelliJ aka not another IDE war. [closed]

    - by Xorty
    I hope you guys won't take this as attempt of flamewar :) I am quite happy Eclipse user atm, but I am having little dilema: All big companies in my area are using Eclipse, and I quite like Eclipse, but IntelliJ is simply smarter and comfortable in some things. What would you do? If I decide to switch to IDEA I am afraid that I'll regret it someday ... And I don't want to remember like all shortcuts in both eclipse & IDEA, that's simply too much :)

  • Auto Selecting Cultures for Localization in ASP.NET

    - by Rick Strahl
    When creating multi-language Web sites, one of the key issues you need to deal with is how to assign a culture to display the appropriate resources. Whether you need to auto-switch locales based on browser language, or explicitly assign a locale based on user preferences there is generally some code logic involved in making these decisions. In this post I show what options are available and a small helper that simplifies setting the culture in ASP.NET applications.

  • Should I blog in english or in my native language?

    - by Jérémy
    I had a blog which was written in my native language, but now I'm wondering if I should switch to english because of a wider audience. For sure, I want to share my knowledge, but at the meantime I'd like to get hired or be recognized from my peers. Reputation can be important and it can help in making my professional network larger. Do you have any feedback? Btw, my native language is french if that matters.

  • How do I correct the kernel version loaded by Grub2 in Ubuntu 12.04

    - by Paul D'Ambra
    I have a linux vps running Ubuntu 12.04 and when I run uname-r it replies: paul@webforms:~$ uname -r 2.6.32.33-kvm-i386-20111128-dirty paul@webforms:~$ sudo grub-install -v grub-install (GRUB) 1.99-21ubuntu3.1 if I run update-grub I get: paul@webforms:~$ sudo update-grub Generating grub.cfg ...

  • How do you manage updates without a staging environment: CentOS 6.3

    - by Gregg Leventhal
    I am managing about 20 servers, many of them virtual. They are almost all different purpose, and none are clustered. I have a distributed LAMP stack, a few application servers, some build servers, a few KVM hosts. They are CentOS 6.3 mostly with a few Ubuntu (unfortunately). I don't have the resources to setup a staging environment where I can have duplicates of my machines and test updates before rolling them out. I am taking file backups. What I want to know is how you are approaching backing up your Linux systems. I assume you don't just do yum update, but then how are you choosing the packages worthy of updating? When (if ever) are you updating the kernel, etc.. How do you test updates without a staging environment? Snapshot and hope for the best?

  • Depth buffer values reset on change shader?

    - by bobobobo
    I have 2 different shaders, and when I change the shader (glUseProgram), it seems that the depth information is lost, because everything drawn with the 2nd shader appears completely on top of anything drawn by the first shader. If I switch the order of shader use/drawing, then it's the same (the last drawn object always appears on top of the first drawn object if there is a shader change between the 2 objects, even if the last drawn object is further away)

    I've been trying to get my dual desktops working on Ubuntu for a while. I previously had them as one large desktop, but that was incredibly slow for some reason. I tried to switch them to multi display desktop on the AMD Catalyst Control Center.

  • 2 internet connections

    - by oshirowanen
    If I have a wireless and a usb internet connection on my Ubuntu 12.04 as in: At the moment, Ubuntu seems to only make use of the Wired connection which is the usb connection. Is it possible to get ubuntu to use the wireless connection without unplugging the wired connection? So basically, as will, I would like to switch between the connections without unplugging any of them while leaving them both enabled. Is this possible?

  • How system services are started in 12.10?

    - by Salem
    One thing that always confused me in Ubuntu was how system services are started. I know that Ubuntu uses Upstart and supports SysV, but which one is used to start the services? This matters when you want a "manual" start for a service. For example, on my system i have files for the following services either in /etc/init.d/<service> (Upstart) and /etc/init/<service>.conf (SysV): acpid, mysql, networking, qemu-kvm, ufw, libvirt-bin So if i want to disable MySQL execution at startup, i must use the Upstart way or the SysV way to disable it? Also, how can i tell which of those is really used to start a generic service? Edit The really doubt here is not how disable/enable services using SysV/Upstart. What really confuses me is that some services seem to be defined (and enabled) in SysV and Upstart at the same time. Is there any precedence between them (like if mysql is enabled in both launch it using SysV)? Or can it be the case that one tool uses the other in background?

  • Any command line calculator for Ubuntu?

    - by AgentCool
    I am looking for a Calculator which can do calculations in the terminal itself without any other extra prefixes and suffixes. For example: If I typed something like 10000-9000 in the terminal, the answer should come out as 1000. Once again I am saying, I just need a quick calculator in terminal, without any characters added. I know if I switch to Python, it can do that but I don't want it in such a way.

  • Solution to Manage and Monitor (Ubuntu) Machines

    - by Elmar Weber
    I'm looking for a tool like Canonical (system management and monitoring for Ubuntu) that is Open Source and free. The goal is to manage a dozen or so KVM machines for private testing purposes. I know of puppet and munin or RHQ as separate tools to manage and monitor, but I'd prefer something integrated. Any tips? Basic requirements would be: system package management and update (individual selection for each managed node) configuration of basic system services (Users, NFS, cron, ideally also Apache) monitoring (charting of system resources, disk, io, memory, etc) and alerting, ideally a default configuration with sensible values for alerts

  • Windows Server 2008 R2 Upgrade via Remote Desktop

    - by Marko
    Is it possible to do an in-place upgrade of Windows Server 2008 R2 to Windows Server 2012 using only Remote Desktop? My plan is to extract WS 2012 installation iso file to C:\WS2012 and run the setup. After restart Remote Desktop connection will be lost, but will it be restored later? Is setup going to automatically install everything, restart, run WS 2012 and start listening for RDP connections? Server is rented and I would like to save the KVM fee. I read here that it's possible to upgrade WS 2008 to WS 2008 R2 like that. Thanks!

  • switching users in byobu session

    - by JohnMerlino
    I launched a byobu session (tmux) and then tried to switch to a user called kommander "su - kommander", it immediately prompted me with: [Oh My Zsh] Would you like to check for updates? Type Y to update oh-my-zsh: Now I usually press "n" and everything is fine, but within the byobu session, when I press enter it just displays a "^M" character. I have no idea how to exit out if this prompt: [Oh My Zsh] Would you like to check for updates? Type Y to update oh-my-zsh: n^M

  • Is it possible to use mac trackpad gestures on a linux virtualbox? (macbook pro)

    - by David
    Specifically, I would just love to use the trackpad to do "three finger swipes" and switch between workspaces, that would just be slick as hell. I imagine this might require a plugin or some such thing, in addition to the disabling of the underlying mac os's responding to the gestures, which is what it currently does. This might be impossible. PS/FYI: I am running ubuntu, but I imagine this might apply to debian builds as well.

  • I need help with specific types of movement.

    - by IronGiraffe
    I'm adding movable crates to my game and I need some help with my movement code. The way I've set up my movement code the crate's X and Y are moved according to a vector2 unless it hits a wall. Here's the movement code: if (frameCount % (delay / 2) == 0) { for (int i = 0; i < Math.Abs(cSpeed.X); i++) { if (!Level.PlayerHit(new Rectangle(crateBounds.X + (Math.Sign(cSpeed.X) * 32), crateBounds.Y, crateBounds.Width, crateBounds.Height))) { if (!Level.CollideTiles(crateBounds.X + (Math.Sign(cSpeed.X) * 32), crateBounds.Y, crateBounds.Width, crateBounds.Height)) { if (cSpeed.X != 0) { crateBounds.X += Math.Sign(cSpeed.X); } else { Equalize(2); } } else { cSpeed.X = 0f; } } else { if (!Level.CollideTiles(crateBounds.X - (Math.Sign(cSpeed.X) * 32), crateBounds.Y, crateBounds.Width, crateBounds.Height)) { if (cSpeed.X != 0) { crateBounds.X -= Math.Sign(cSpeed.X); } else { Equalize(2); } } else { cSpeed.X = 0f; } } } for (int i = 0; i < Math.Abs(cSpeed.Y); i++) { if (!Level.PlayerHit(new Rectangle(crateBounds.X, crateBounds.Y + Math.Sign(cSpeed.Y), crateBounds.Width, crateBounds.Height))) { if (!Level.CollideTiles(crateBounds.X, crateBounds.Y + Math.Sign(cSpeed.Y), crateBounds.Width, crateBounds.Height)) { crateBounds.Y += Math.Sign(cSpeed.Y); } else { cSpeed.Y = 0f; } } else { if (!Level.CollideTiles(crateBounds.X, crateBounds.Y - Math.Sign(cSpeed.Y), crateBounds.Width, crateBounds.Height)) { crateBounds.Y -= Math.Sign(cSpeed.Y); } else { cSpeed.Y = 0f; } } } } The frameCount and delay variables just slow down the movement somewhat. Anyway, I've added a tool to my game that acts as a gravity well (drawing objects into it's center; the closer they get to the center the faster they go) and what I'm trying to do is make it so that the crate will bounce off the player (and vice versa) when they collide. Thus far, my code only keeps the crate and player from getting stuck inside each other (the player can still get stuck under the crate, but I'll fix that later.) So what I'd like to know is how I can best make the crate bounce off the player. The other movement problem I'm having is related to another tool which allows the player to pick up crates and move around with them. The problem is that the crate's movement while being carried isn't tied to the movement script (it moves the crate itself, instead of adding to speed), which makes the crate go through walls and such. I know what I have to do: make the crate's speed match the player's speed while the player is holding it, but I need the crate to snap to a certain position (just in front of the player) when the player grabs it and it needs to switch to another position (just in front of the player on the other side) when they player faces the other direction while holding it. What would be the best way to make it switch places while keeping all the movement tied to the speed vector?

  • virsh console and tty size

    - by pehrs
    I have a virtualization server to which I connect over ssh. If I now change the size of the window it will automatically propagate to the server. It's most easily seen using stty -a, checking the columns and row values. I then use virsh console to connect to the serial interface on a KVM based virtual machine. When I now change the size of the window it does not propagate to the virtual server. This is most easily seen by checking stty -a, which is not updated on the virtual machine when I change window size. This means that line breaks does not work correctly in the terminal and any application that relies on window size for formatting (emacs, man, etc) gets messed up unless the window size on the client matches the default size on the server. A workaround is to manually set the window size to match the client window using stty, but I wonder if there is any way to get this information to propagate and set the window size in the virtual machine automatically.

  • Switching from an Ubuntu derivative to original Ubuntu

    - by SteliosSk
    I installed Zorin 6 (based on Ubuntu 12.04), because I like all the whistles it has (plymouth screen,compiz effects,installed codecs, sound themes, etc.). I miss though the modern and futuristic unity environment (launcher, dash, HUD, indicators etc.). Is there a way to switch from Zorin to Ubuntu 12.04.1 LTS and keep all these effects? Or What additional software should I install in an Ubuntu clean install to add the effects Zorin has (plymouth, compiz effects, sounds, audio and video codecs etc.)
