  • Non-trivial desktop apps that use Ruby?

    - by Mark A. Nicolosi
    I'm about to start a project developing a Ruby desktop application. I expect to to be fairly big and I want to learn techniques for dividing code among modules and other techniques for managing complexity. Most large apps I've looked at are Rails apps, but these aren't very helpful, because most of the work is done by Rails itself. What source code would you recommend I take a look at? I'm not interested in libraries or Rails apps, because I get how they do things. CLI apps are OK, but I'm mostly interested in GUI apps (I'm using Gtk+, but I can learn just as much from apps using other GUI toolkits).

  • View OS X Desktop on windows remotely at higher resolution then hosting machine

    - by Elijha
    I have a new macbook air 11, which I do some web based programming on, I have a windows box with a 1920x1200 display which I'd like to use to view the mac desktop and keep working at home when I can - taking advantage of the higher resolution screen and full sized keyboard/mouse. I don't think VNC or such is the answer I'm looking for as it would restrict the display to the airs 1366x768 - negating the main benefit more lines of text on screen. From some rudimentary googleing I think I'm after some sort of x-windows / x-11 remote display. But I'm not a Linux user and any discussion seems to be about linux os x or windows Linux setups. Can anyone provide a clear set of instructions on how to do this or an application that can do this.

  • 64-bit 13.10 shows 1GB less RAM than 64-bit 13.04 did

    - by kiloseven
    Multiple 64-bit versions (Kubuntu, Lubuntu and Xubuntu) once installed on my ThinkPad R60 show 3GB of RAM, not the correct 4GB of RAM. Last week with 13.04, I had 4GB of RAM (which matches the BIOS) and this week I have 3GB available. Inquiring minds want to know.

  • How to achieve 'Activities' in Unity?

    - by Ralf Hersel
    I like the concept of an activities centric desktop and I wonder if this can be achieved in Unity. For me, an activity is a couple of applications that belong to the same subject, like 'photo manipulation', 'software development', 'office work', 'social activities', 'music and video'. I would like to utilize the virtual desktops to arrange applications that belong to the same activity group. Example: Desktop 1 contains all applications that belong to 'office work' Desktop 2 contains all applications that I need for 'software development' Desktop 3 contains all applications that I usually need for 'photo works' Therefore I would like to give names to the virtual desktops that reflect their purpose. And I would like Unity to auto-start the required applications when I start my computer or when I switch to one of the virtual desktops. Is this possible with Unity (or any other desktop)?

  • Virtual Windows desktop

    - by Zack
    Is there any virtual desktop software that can virtualize desktop just like a virtual desktop to sandbox (sort of like virtualization and sandbox combined). I want to create many desktop and each of them must be sandbox. For example if I have virus infected in one of the desktop, I just have to clear or close the desktop and everything is fine. Is there any software that can do that kind of jobs that I have mentioned? Remember I am not asking recommendation of software, but the software that can do the job. UPDATE: I mean that every virtual desktop is working as a virtual box or sandbox. Clearing or closing the desktop will work as shutting down that virtual box.

  • What's the environment variable for the path to the desktop?

    - by Scott Langham
    I'm writing a Windows batch file and want to copy something to the desktop. I think I can use this: %UserProfile%\Desktop\ However, I'm thinking, that's probably only going to work on an English OS. Is there a way I can do this in a batch file that will work on any internationalized version? UPDATE I tried the following batch file: REG QUERY "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders" /v Desktop FOR /F "usebackq tokens=3 skip=4" %%i in (`REG QUERY "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders" /v Desktop`) DO SET DESKTOPDIR=%%i FOR /F "usebackq delims=" %%i in (`ECHO %DESKTOPDIR%`) DO SET DESKTOPDIR=%%i ECHO %DESKTOPDIR% And got this output: S:\REG QUERY "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders" /v Desktop HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders Desktop REG_EXPAND_SZ %USERPROFILE%\Desktop S:\FOR /F "usebackq tokens=3 skip=4" %i in (`REG QUERY "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folder s" /v Desktop`) DO SET DESKTOPDIR=%i S:\FOR /F "usebackq delims=" %i in (`ECHO ECHO is on.`) DO SET DESKTOPDIR=%i S:\SET DESKTOPDIR=ECHO is on.

  • How can I make full-screen desktop applications only cover the snapped desktop?

    - by nhinkle
    In Windows 8, you can "snap" two apps next to each other, and one of those apps can be the legacy Windows desktop environment. A convenient application for this (or so I thought) would be to snap a chat client, small browser, or other app while watching content in full-screen on the desktop. The problem with this is that full screen desktop applications will take over the entire screen, even if the desktop is snapped to only occupy 3/4th of the display. What I would like is some way to force "full screen" desktop apps to only cover the snapped desktop area, and to truly go full screen if the desktop is snapped to full-width. Is there some way to configure this? If that didn't make sense, let me illustrate with pictures: Desktop in snapped view with SU chat in mini-browser: What happens when you click "full screen": What I want to happen when I click "full screen" (note this is digitally altered, not a real screenshot)

  • Searching For a Desktop Security Software to harden Windows machines, anybody?

    - by MosheH
    I'm a network administrator of a small/medium network. I'm looking for a software (Free or Not) which can harden Windows Computers (XP And Win7) for the propose of hardening standalone desktop computers (not in domain network). Note: The computers are completely isolated (standalone), so i can't use active directory group policy. moreover, there are too many restriction that i need to apply, so it is not particle to set it up manual (one by one). Basically what I’m looking for is a software that can restrict and disable access for specific user accounts on the system. For Example: User john can only open one application and nothing else -- He don’t see no icon on the desktop or start menu, except for one or two applications which i want to allow. He can't Right click on the desktop, the task-bar icons are not shown, there is no folder options, etc... User marry can open a specific application and copy data to one folder on D drive. User Dan, have access to all drives but cannot install software, and so on... So far ,I've found only the following solutions, but they all seems to miss one or more feature: Desktop restriction Software 1. Faronics WINSelect The application seems to answer most of our needs except one feature which is very important to us but seems to be missing from WINSelect, which is "restriction per profile". WINSelect only allow to set up restrictions which are applied system-wide. If I have multiple user accounts on the system and want to apply different restrictions for each user, I cant. Deskman (No Restriction per user)- Same thing, no restriction per profile. Desktop Security Rx - not relevant, No Win7 Support. The only software that I've found which is offering a restriction per profile is " 1st Security Agent ". but its GUI is very complicated and not very intuitive. It's worth to mention that I'm not looking for "Internet Kiosk software" although they share some features with the one I need. All I need is a software (like http://www.faronics.com/standard/winselect/) that is offering a way to restrict Windows user interface. So if anybody know an Hardening software which allows to set-up user restrictions on Windows systems, It will be a big, big, big help for me! Thanks to you all

  • Can Remote Desktop Services be deployed and administered by PowerShell alone, without a Domain in WIndows Server 2012 and 2012 R2?

    - by Warren P
    Windows Server 2008 R2 allowed deployment of Terminal Server (Remote Desktop Services) without a domain, and without any insistence on domains. This was very useful, especially for standalone virtual or cloud deployments of a server that is managed remotely for a remote client who has no need or desire for any ActiveDirectory or Domain features. This has become steadily more and more difficult as Microsoft restricts its technologies further and further in each Windows release. With Windows Server 2012, configuring licensing for Remote Desktop Services, is more difficult when not on a domain, but possible still. With Windows Server 2012 R2 (at least in the preview) the barriers are now severe: The Add/Remove Roles and Features wizard in Windows Server 2012 R2 has a special RDS deployment mode that has a rule that says if you aren't on a domain you can't deploy. It tells you to create or join a domain first. This of course comes in direct conflict with the fact that an Active Directory domain controller should not be the same machine as a terminal server machine. So Microsoft's technology is not such much a Cloud Operating System as a Cluster of Unwanted Nodes, needed to support the one machine I actually WANT to deploy. This is gross, and so I am trying to find a workaround. However if you skip that wizard and just go check the checkboxes in the main Roles/Features wizard, you can deploy the features, but the UI is not there to configure them, and when you go back to the RDS configuration page on the roles wizard, you get a message saying you can not administer your Remote Desktop Services system when you are logged in as a Local-Computer Administrator, because although you have all admin priveleges you could have (in your workgroup based system), the RDS configuration UI will not accept those credentials and let you continue. My question in brief is, can I still somehow, obtain the following end result: I need to allow 10-20 users per system to have an RDS (TS) session. I do not need any of the fancy pants RDS options, unless Microsoft somehow depends on those features being present. I believe I need the "RDS Session Host" as this is the guts of "Terminal Server". Microsoft says it is "full Windows desktop for Remote Desktop Services client. I need to configure licensing so that the Grace Period does not expire leaving my RDS non functional, so this probably means I need a way to configure TS CALs. If all of the above could technically be done with the judicious use of the PowerShell, I am prepared to even consider developing all the PowerShell scripts I would need to do the above. I'm not asking someone to write that for me. What I'm asking is, does anyone know if there is a technical impediment to what I want to do above, other than the deliberate crippling of the 2012 R2 UI for Workgroup users? Would the underlying technologies all still work if I manipulate and control them from a PowerShell script? Obviously a 1 word Yes or No answer isn't that useful to anyone, so the question is really, yes or no, and why? In the case the answer is Yes, then how.

  • Unable to remove/hide icons from desktop folder

    - by Kyomu
    I wish to hide some windows icons from my desktop folder1, but cannot. When I click delete, it says they will be deleted from my desktop (which they already are), but they remain visible in the desktop folder, which is where I wish them removed. Is there any way I can remove these? (I always use Win+E which really lets me get to all of these easy enough). Offending icons: Libraries, Homegroup, User folder, Computer, Network, Control Panel, and Recycle Bin. For those who might be wondering why, I find myself in this folder a bit to often (including when uploading a file), and find these nothing but clutter, especially as these always default to the top. Thanks for your help! 1 By desktop folder, I mean the folder you would see by going to "My Computer" and clicking "Desktop" on the top left under Favorites. Note: Changing my "Desktop Icon Settings" under "Personalize" does not affect the desktop folder, but rather just the desktop view.

  • Integrated webcam in lenovo t410 not working with 12.04

    - by kristianp
    I have a Lenovo T410 with an inbuilt webcam and I haven't been able to get the webcam working. I tried skype, cheese, both just give me a black window. The microphone works fine with skype, by the way. Can anyone provide any clues please? The webcam is enabled in the bios, but there is no light indicating the webcam is on (not sure if there should be, though). I tried this on Kubuntu 11.10 and have upgraded to 12.04 with the same results. The Fn-F6 keyboard combination doens't seem to do anything either. EDIT: I got the webcam replaced, it looks like it was a hardware problem, because it works fine now.

  • HTG Explains: What You Can (and Can’t) Do on the Desktop in Windows RT

    - by Chris Hoffman
    Windows RT and Windows 8 aren’t the same thing. While Windows RT has a desktop that looks just like Windows 8’s, Windows RT’s desktop is very limited. The difference doesn’t just matter to geeks; it matters to all Windows users. We’ve explained the difference between Windows RT and Windows 8 before. Unlike Windows RT, Windows 8 includes a fully functional desktop (although there’s no Start menu by default.) 6 Ways Windows 8 Is More Secure Than Windows 7 HTG Explains: Why It’s Good That Your Computer’s RAM Is Full 10 Awesome Improvements For Desktop Users in Windows 8

  • How To Manage Your Remote Desktop Connections Easily

    - by Gopinath
    If you regularly access PCs using Microsoft Remote Desktop Connection, here is an nice utility to make your life easier. Remote Desktop Organizer is a freeware application that allows you to easily organize your multiple remote desktop connection in one place. It has many useful features(we run them down after the break) but my favorites are the ability to organize & save connection details and the ease at which it allows to switch between multiple connections. The above screen grab of the applications shows how well we can save & organize multiple connection by creating folders hierarchy and also multiple Remote Connections in one window for easy switching. These two features are huge time savers to me as I often connect to multiple servers and switch between them. The complete list of features as given by the official website of the freeware Organize remote desktop connections in folders and subfolders Drag and drop support for moving connections and folders Tabbed connections Quick Connection Connect to console Change connection port Minimize to system tray (optional) Close to system tray (optional) To run this application you need Microsoft .NET Framework 2.0 or higher installed on your PC.

  • Yes WinRT Devices Have a Desktop&hellip;But Not For Us

    - by D'Arcy Lussier
    So tonight this convo happened: Intrigued, I viewed the video Lee mentions and found that its the now infamous Brent Ozar video which shows a bug in Word on the Surface RT (you can read this article which talks about the tempest in a teacup that ensued). But Lee is correct – in the video, when Brent starts up Word 2013, we see this: That sure does look like a desktop doesn’t it! But…aren’t Windows RT devices *not* supposed to come with a desktop? Actually, it does. However, it’s not a *full* desktop. From Seth Rosenblatt’s fantastic Windows RT FAQ article: Windows RT will have a Desktop mode, but it will be restricted to pre-installed, Microsoft-produced software. This will include touch-optimized versions of Microsoft Word, Excel, PowerPoint, and OneNote as the new Microsoft Office So yes, there’s a desktop mode in Windows RT but no, you won’t be able to install apps to it. Confused yet? Read the rest of the Seth’s FAQ – it does a great job clearing the haze of confusion that Microsoft Marketing Merlins have cast upon all of us. D

  • How to get the Ubuntu look back after installing lubuntu-desktop

    - by Wauzl
    I have a fresh install of Ubuntu 13.10. I wanted to try out Lubuntu, so I installed the package lubuntu-desktop. Everthing worked fine, I can do Lubuntu sessions now, as well as normal Ubuntu sessions with unity. I realized that I liked unity better. Unfortunately, since I installed lubuntu-desktop my login screen and my notifications look different. How can I revert this and get my old Ubuntu look back? I already removed the package lubuntu-desktop, but it did’t help. Also, when I installed it, it came with a lot of packages that weren’t removed when I removed lubuntu-desktop

  • unity top menu keyboard shortcuts for desktop alone, no programs running

    - by user108754
    Alt+F1 accesses the launcher menu, with arrow keys to navigate the list (side menu). Alt+F10 accesses the top bar in an open application (or Alt+an underlined menu item letter), which allows access to the global ubuntu settings in the top right (battery, wifi/networking, audio, time/calendar, user, power). Alt+F10, when no application is open and you're just staring at the desktop, accesses those ubuntu settings immediately. But the top menu bar does list, in the top left, menu commands for the desktop per se (create new folder, go home, help, start server, etc). These can be accessed only by mouse hovering and click. No way to get to them only by keyboard (arrow keys just cycle through the settings, don't jump over to the left side of the top bar). Is there a keyboard shortcut way to access the desktop menu bar for manipulating icons on your desktop and other general things? Or is this a work in progress for unity? If you use the context menu key (or some equivalent you've set to generate that signal) along with other shortcuts for working on the desktop, you can cover most of the functionality of the top menu bar. However, I don't want to memorize those keys to become proficient. I just want a way to open and browse through those menu items (and they aren't ALL available through hotkeys anyway).

  • trying live-usb 12.04.1 image on an old desktop

    - by 213441265152351
    I am trying to load Ubuntu 12.04.1 32-bit desktop image on an old desktop computer. The system shows the initial menu, but after a while, I get an error like the one in the following two screenshots (it takes a few seconds to go from one to the other in the screen): I tried to load it using the different USB ports at the back of the computer, just in case, and I get basically the same error. Find another screenshot from another try: Any ideas what might be happening? NOTES: I checked the md5sum of the iso file to be e235b63c02644e219b7bf3668f479c9e *ubuntu-12.04.1-desktop-i386.iso. I did the 'Test' on the laptop where I created the USB drive, and it loads up correctly. The desktop computer in question is an old AMD Duron 1800MHz with 512MB RAM. I ran a memtest on the computer, and all went fine.

  • Remove packages to tranform ubuntu Desktop to Server?

    - by Azendale
    I have a VPS that has Ubuntu 11.10 on it. Unfortunately, only the 11.10 Desktop (not server) image was available as an image to install your VPS with. How can I remove the packages included in the Desktop install, and, if needed, install the packages that only the server install has? I've tried sudo apt-get remove ubuntu-desktop and then sudo apt-get autoremove. Unfortunately, that didn't work: it only removed 'libjudy-debian' (or something like that) which was installed from having 'miredo' installed at one point.

  • How to modify the default position of desktop icons

    - by Hanynowsky
    Is it possible to modify the default desktop icons position so that icons move a little bit to right. If yes, how? As far as I know, there is no tweak for that in Nautilus. When I click "Organize Desktop by Name", the icons get aligned to the left of Desktop: that's fine, but they're too close to the launcher when it's in AUTO HIDE mode. So when Launcher is revealed, it comes over icons. Reproduce: Download some files from your browser or copy files/folders from a folder to the desktop, then these latter will be placed just like the screenshot. Their position is fine when the launcher is hidden, but when revealed, it hides a part of the icons. There is no problem when LAUNCHER AUTO-HIDE MODE is disabled. Thanks in advance.
