• Running python batch file that has a path with SPACE character

  - by prosseek

  The batch file is something like this, I put the python in some directory that has SPACE character in its path. C:\"Documents and Settings"\Administrator\Desktop\bracket\python\python C:\\"Documents and Settings"\\Administrator\\Desktop\\bracket\\[10,20]\\brackettest.py When I run this one, I get this error. C:\Documents and Settings\Administrator\Desktop\bracket\python\python: can't ope n file 'C:\Documents and Settings\\Administrator\\Desktop\\bracket\\[10,20]\\bra ckettest.py': [Errno 2] No such file or directory C:\Documents and Settings\Administrator\Desktop\bracket What might be wrong? Wrapping the path doesn't solve this problem. "C:\\Documents and Settings\\Administrator\\Desktop\\bracket\\[10,20]\\brackettest.py" Are the brackets ('[]') cause of the problem? On Mac, python works well with bracket character.

• ASP.NET MVC4: How to convert an IEnumerable to a string for ViewBag

  - by sehummel

  This is what I'm trying to do, but it doesn't work: HardwareType hwt = new HardwareType { HType = "PC" }; IEnumerable<Hardware> Pcs = db.Hardware.Where(h => h.HardwareType.Contains(hwt)); ViewBag.Pcs = Pcs.ToString(); So how do I convert my IEnumerable to a string (or other primitive data type) so the compiler won't give me an error when I try to use it in my Razor? @foreach (var item in ViewBag.Pcs) { <li><a href="#" class="btn"><i class="icon-hdd"></i> @item.HType</a></li> }

• Fun Visual Studio 2010 Wallpapers

  - by ScottGu

  Two weeks ago I blogged about a cool new site that allows you to download and customize the Visual Studio code editor background and text colors (for both VS 2008 and VS 2010 version). The site also allows you to submit and share your own Visual Studio color schemes with others. Another new community site has recently launched that allows you to download Visual Studio 2010 themed images that you can use for your Windows desktop background.  You can visit the site here: http://vs2010wallpapers.com/  In addition to browsing and downloading Visual Studio themed wallpapers, you can also submit your own into the gallery to share with others. [In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu] Browsing Wallpaper Images The site has dozens of wallpaper images that you can browse through and choose from.  They range from the cool and abstract: To the fun and silly: Enabling the Wallpaper Images as your Windows Desktop You can zoom in on any image (hover over the image and then click the “zoom” button that appears over it) and then download it to be your Windows desktop image.  If you visit the site using Internet Explorer, you can also zoom in on the image, then right click on the image and choose the “Set as Background” context menu item to enable it as your Windows desktop. Note: you want to make sure you download the zoomed-in/high resolution version of the wallpaper to make sure it looks good as the wallpaper on your desktop. Hope this helps, Scott

• Windows 8: Is Internet Explorer10 Metro mode disabled? Here is the fix.

  - by Gopinath

  Are you having issues with Internet Explorer 10 on Windows 8? Is Internet Explorer 10 application not launching in Metro mode and always launching in Desktop mode? Continue reading the post to understand and fix the problem. When Internet Explorer 10 does not launch in Metro mode? On Windows 8 when Internet Explorer is launched from Start screen it launches in Metro UI mode and when launched from Desktop it launches in traditional desktop UI mode. But when Internet Explorer  is not set as default browser, Windows 8 always launches Internet Explorer in Desktop mode irrespective of whether its launched from Start screen or Desktop. This generally happens when we install the browsers Firefox or Chrome and set them as default browser. How to restore Internet Explorer 10 Metro mode? The problem can be resolved by setting Internet Explorer 10 as the default web browser in Windows 8. But setting default web browser in Windows 8 is a bit tricky as there is no option available Options screen of  of Internet Explorer. To set Internet Explorer 10 as the default web browser follow these steps 1. Go to Start screen of Windows 8 and search for Default Programs app by typing Default using keyboard. 2. Click on the link Set your default programs 3. Choose Internet Explorer on the left section of the screen(pointer 1) and then click on the option Set this program as default available at the bottom right section(pointer 2) 4. That’s it. Now Internet Explorer is set as default web browser and from now onwards you will be able to launch Metro UI based Internet Explorer from Start screen

• Is it possible to update from Windows 8 Enterprise to version 8.1 without having to reinstall the OS?

  - by foregon

  Today we are told that the 8.1 update, (a version which allows you to keep apps, settings, and files), is officially being rolled out worldwide. No longer will you have to do a clean OS install, to go from 8 to 8.1. But I don't see the update inside my (Enterprise's) desktop 'Windows Update' program, and furthermore, Microsoft themselves say: If you’re running [Enterprise], you can't install the free update to Windows 8.1 or Windows RT 8.1 from the Store. However they DO also say: If you installed Windows 8 using an MSDN ISO, you might be able to install Windows 8.1 using a similar ISO from MSDN But it does not specify whether this method allows seamless apps and settings-retaining upgrading or not. Is there a method for doing it (whether official or unofficial - perhaps confirmed via experience of updating with some sort of Enterprise 8.1 ISO), or is an update indeed expected for the Enterprise version via the desktop 'Windows Update' program? A further observation which may help: the page I cite refers to the 'Windows Store', which is the 'Modern UI' app store and NOT the desktop 'Windows Update' program which typically updates desktop Office and desktop Windows alike.

• can't start vino VNC service on Ubuntu 12.04

  - by user1689961

  I just installed vino, but when I run it, I get the following error. # ./start_vnc (vino-server:2502): EggSMClient-CRITICAL **: egg_sm_client_set_mode: assertion `global_client == NULL || global_client_mode == EGG_SM_CLIENT_MODE_DISABLED' failed ** Message: The desktop sharing service is already running, exiting. MORE DETAILS: UltraVNC client running on a Windows computer can login and shows the Ubuntu desktop, and controls the Ubuntu mouse to do things, but the VNC client view at the Windows computer does NOT show any changes to the display at the Ubuntu desktop, only the original desktop view at the time of VNC client login. UPDATE I solved it by following the askubuntu post: "VNC session very slow in 12.04 compared to older versions", which said to do this: gsettings set org.gnome.Vino disable-xdamage true ..and it worked. But should I be concerned about the error messages?

• Windows 8.1 Will Start Encrypting Hard Drives By Default: Everything You Need to Know

  - by Chris Hoffman

  Windows 8.1 will automatically encrypt the storage on modern Windows PCs. This will help protect your files in case someone steals your laptop and tries to get at them, but it has important ramifications for data recovery. Previously, “BitLocker” was available on Professional and Enterprise editions of Windows, while “Device Encryption” was available on Windows RT and Windows Phone. Device encryption is included with all editions of Windows 8.1 — and it’s on by default. When Your Hard Drive Will Be Encrypted Windows 8.1 includes “Pervasive Device Encryption.” This works a bit differently from the standard BitLocker feature that has been included in Professional, Enterprise, and Ultimate editions of Windows for the past few versions. Before Windows 8.1 automatically enables Device Encryption, the following must be true: The Windows device “must support connected standby and meet the Windows Hardware Certification Kit (HCK) requirements for TPM and SecureBoot on ConnectedStandby systems.”  (Source) Older Windows PCs won’t support this feature, while new Windows 8.1 devices you pick up will have this feature enabled by default. When Windows 8.1 installs cleanly and the computer is prepared, device encryption is “initialized” on the system drive and other internal drives. Windows uses a clear key at this point, which is removed later when the recovery key is successfully backed up. The PC’s user must log in with a Microsoft account with administrator privileges or join the PC to a domain. If a Microsoft account is used, a recovery key will be backed up to Microsoft’s servers and encryption will be enabled. If a domain account is used, a recovery key will be backed up to Active Directory Domain Services and encryption will be enabled. If you have an older Windows computer that you’ve upgraded to Windows 8.1, it may not support Device Encryption. If you log in with a local user account, Device Encryption won’t be enabled. If you upgrade your Windows 8 device to Windows 8.1, you’ll need to enable device encryption, as it’s off by default when upgrading. Recovering An Encrypted Hard Drive Device encryption means that a thief can’t just pick up your laptop, insert a Linux live CD or Windows installer disc, and boot the alternate operating system to view your files without knowing your Windows password. It means that no one can just pull the hard drive from your device, connect the hard drive to another computer, and view the files. We’ve previously explained that your Windows password doesn’t actually secure your files. With Windows 8.1, average Windows users will finally be protected with encryption by default. However, there’s a problem — if you forget your password and are unable to log in, you’d also be unable to recover your files. This is likely why encryption is only enabled when a user logs in with a Microsoft account (or connects to a domain). Microsoft holds a recovery key, so you can gain access to your files by going through a recovery process. As long as you’re able to authenticate using your Microsoft account credentials — for example, by receiving an SMS message on the cell phone number connected to your Microsoft account — you’ll be able to recover your encrypted data. With Windows 8.1, it’s more important than ever to configure your Microsoft account’s security settings and recovery methods so you’ll be able to recover your files if you ever get locked out of your Microsoft account. Microsoft does hold the recovery key and would be capable of providing it to law enforcement if it was requested, which is certainly a legitimate concern in the age of PRISM. However, this encryption still provides protection from thieves picking up your hard drive and digging through your personal or business files. If you’re worried about a government or a determined thief who’s capable of gaining access to your Microsoft account, you’ll want to encrypt your hard drive with software that doesn’t upload a copy of your recovery key to the Internet, such as TrueCrypt. How to Disable Device Encryption There should be no real reason to disable device encryption. If nothing else, it’s a useful feature that will hopefully protect sensitive data in the real world where people — and even businesses — don’t enable encryption on their own. As encryption is only enabled on devices with the appropriate hardware and will be enabled by default, Microsoft has hopefully ensured that users won’t see noticeable slow-downs in performance. Encryption adds some overhead, but the overhead can hopefully be handled by dedicated hardware. If you’d like to enable a different encryption solution or just disable encryption entirely, you can control this yourself. To do so, open the PC settings app — swipe in from the right edge of the screen or press Windows Key + C, click the Settings icon, and select Change PC settings. Navigate to PC and devices -> PC info. At the bottom of the PC info pane, you’ll see a Device Encryption section. Select Turn Off if you want to disable device encryption, or select Turn On if you want to enable it — users upgrading from Windows 8 will have to enable it manually in this way. Note that Device Encryption can’t be disabled on Windows RT devices, such as Microsoft’s Surface RT and Surface 2. If you don’t see the Device Encryption section in this window, you’re likely using an older device that doesn’t meet the requirements and thus doesn’t support Device Encryption. For example, our Windows 8.1 virtual machine doesn’t offer Device Encryption configuration options. This is the new normal for Windows PCs, tablets, and devices in general. Where files on typical PCs were once ripe for easy access by thieves, Windows PCs are now encrypted by default and recovery keys are sent to Microsoft’s servers for safe keeping. This last part may be a bit creepy, but it’s easy to imagine average users forgetting their passwords — they’d be very upset if they lost all their files because they had to reset their passwords. It’s also an improvement over Windows PCs being completely unprotected by default.

• Can I get my video card to output a DVI and VGA signal at the same time?

  - by Roy Pardee

  Hey All, I've got: a lovely 24" monitor, w/both DVI and VGA inputs, a personal desktop w/a Radeon HD Pro 2400 video card (both DVI and VGA outputs) a work laptop w/both outputs, and a KVM switch that handles VGA only Right now I've got laptop connected to the monitor's VGA, and the desktop connected to the DVI. This works, but requires me to switch the KVM and monitor input sources separately, which annoys me (I switch back & forth a lot to make skype calls & manage my music). I'd like to feed both VGA and DVI signals out of my desktop so I can do quick things on my desktop & switch right back, but then when I'm done working, switch the monitor over to DVI to get the crisper picture. Alas, just attaching both VGA and DVI cables to my desktop's video card did not do the trick. Can this card be persuaded to output both signals at the same time? Many thanks! -Roy

I have also disabled automount in Nautilus preferences by using dconf-editor (following this post): user@server:~$ gsettings list-recursively org.gnome.desktop.media-handling org.gnome.desktop.media-handling automount false org.gnome.desktop.media-handling automount-open false org.gnome.desktop.media-handling autorun-never false Now i see every mount device twice in Nautilus (the entry in fstab already mounted). When clicking on the other entry i get the eligible message mount.nfs: /media/nas_share is busy or already mounted How i can i disable the appearente of those devices in Nautilus? EDIT Regarding automount: I have only one line in /etc/auto.master: +auto.master

• Seamless Mode Not Working Correctly in Virtual Box

  - by Jeremy

  I run Ubuntu Desktop in a VirtualBox seamless mode, hosted on Windows 7. I recently upgraded from 11.10 to 12.04 and seamless mode no longer works correctly. I have re-installed guest extensions. The problem is that the Ubuntu desktop wallpaper is shown, effectively blocking the Windows desktop. I can bring Windows apps to the foreground, but as soon as I bring any Ubuntu window to the foreground, all the windows apps will disappear, hidden by the ubuntu desktop even if I activated an Ubuntu window in a different monitor. So, it is not very much different from full-screen mode at this time. I suspect if I could turn off the Ubuntu desktop or wallpaper this would be a sufficient workaround (this is basically what Seamless mode is) but that does not seem to be possible within Ubuntu itself. [Jeremy doesn't specify system config, but I can confirm I'm seeing this behavior in Win 7 64-bit with both 32-bit and 64-bit guests. Giovanni sees the same thing on his laptop running Vista Ultimate 64 bit after upgrading his 32-bit guest to 12.04 (forums.virtualbox.org p225407, requires logging in with your free Oracle account). I was using vbox 4.1.14r77440 and matching Guest Additions. I upgraded to 4.1.16-78094 vbox+additions. Still a problem. And I filed launchpad bug 999929 to see if I can get feedback from developers. – tbc0] Any other ideas?

• How to create a PPA for C++ program?

  - by piotr

  My questions are: c++/gtkmm project created with NetBeans. How to make package to PPA from this? I have created target files structure (*.desktop, iconfile, ui glade files). Binary goes to /opt/extras.ubuntu.com/myagenda/bin/myagenda. There is also a folder of glade files, that must go to /opt/extras.ubuntu.com/myagenda/bin/myagenda/ui. Desktop file goes to /usr/share/applications/myagenda.desktop. Icon goes to /usr/share/icons/hicolor/scalable/apps/myagenda.svg As you see, there is really small amount of files. Now, how to manage all this stuff, to create package on PPA, which knows where and how put this files to their targets? +-- opt ¦   +-- extras.ubuntu.com ¦   +-- myagenda ¦   +-- bin ¦   ¦   +-- myagenda ¦   +-- ui ¦   +-- item_btn_delete.png ¦   +-- item_btn_edit.png ¦   +-- myagenda.png ¦   +-- myagenda.svg ¦   +-- reminder.png ¦   +-- ui.glade +-- usr +-- share +-- applications ¦   +-- myagenda.desktop +-- icons +-- hicolor +-- scalable +-- apps +-- myagenda.svg Update: Created install file in debian directory with targets: data/myagenda /opt/extras.ubuntu/com/myagenda/bin data/ui/* /opt/extras.ubuntu/com/myagenda/ui data/myagenda.desktop /usr/share/applications data/myagenda.svg /usr/share/icons/hicolor/scalable/apps After dpkg-buildpackage it builds, but for amd64 architecture.

• Are there any plans to create a standard based on libunity?

  - by Sebastian Billaudelle

  In the last few month and maybe even years, Ubuntu and Canonical often were criticised for developing software and desktop components without talking to other groups in the free software community. I don't want to comment on this topic, but I see problems arising with creating a "proprietary" solution for displaying indicators and progressbars with a launcher like Unity. In the world of free and open Desktop Environments we often try to standardize parts and libraries or write specifications to increase collaboration between different desktops. We have the instrument of http://freedesktop.org and a lot of specifications are getting implemented by the major Desktop Environments. In this context, proposing a standard for those indicators would be a great step towards better interoperability between desktops. These indicators represent a great feature on the Linux Desktop and I'm sure that other projects like AWN, Docky, etc. would pick them up. With the great market share of Ubuntu, Canonical is in a position to propose it as a standard and encourage projects to implement it. Thank you in advance, Sebastian Billaudelle
