• 12.04 Epson Scanner will not install dependency not met

  - by Howard Graham

  I'm trying to install Epson V100 scanner in 12.04. I downloaded files from Epson: iscan_2.29.1-5~usb0.1.ltdl7_amd64.deb iscan_2.29.1-5~usb0.1.ltdl3_amd64.deb iscan-plugin-gt-s600_2.1.2-1_amd64.deb from Ubuntu Software Center via double click on the file or from the terminal "dependencies not met" error occurs. What can I do. Apparently 12.04 is not able to process these files. Does anyone know where I can download older versions of the above files. I can not access avasys.jp from my location in China.

• Slowdowns while using Firefox

  - by aneal

  I have Windows 7 and Natty installed on my computer. There is no problem on Windows 7's side, but whenever I log into Natty, it slows down while using Firefox 4. I tried it in normal mode using Unity and classic mode. However, the result is the same: it slows down e.g. when I scroll, it takes time to get effect, and also when I click other tabs, it takes time to active them. Moreover I cannot type properly, due to the lag. I don't know what the problem is?

• Ubuntu on AMD based Sony Vaio VPCY B15AG

  - by Gaurav

  Last week I bought a AMD E350 (AMD Fusion platform) based Sony VAIO (VPCYB15AG) having AMD Radeon HD 6310 graphics, I removed Windows that came along with and installed Ubuntu 10.10 (AMD64) using USB drive. During installation my touchpad was not working, I managed through keyboard, but after completing installation & restarting the machine still there was no touchpad support. Also there's no proper graphic card drivers. Even I tried connecting the USB mouse to it but the left key is not working and had to configure the mouse as left-hand to get the left click enabled. I tried searching for any possible solutions for these but found nothing helpful, is there any hope? What should I do to enable i) enable touch pad support ii) get higher resolution 1366x768, etc?

• I can't open Ubuntu Software Center

  - by user165700

  I downloaded google chrome that was made for my computer from https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb. For some reason after I installed I can't open. Also in the corner where the time and other things are there's this red circle with a white dash in the middle of it. It says "An error occured, please run package manager from the right click menu or apt-get in a terminal to see what is wrong. The error message was: 'Unknown Error:''(E:The package google-chrome-stable needs to be reinstalled,but I can't find an archive for it.)' This usually means that your installed packages have unmet dependencies.

• Blank space on right side of screen with XMonad/Gnome

  - by Andrew

  Fresh install of 11.10 x64. I set up XMonad with gnome-session as I did before on 11.04, following the guide on the Arch wiki. Everything works, but there's this weird vertical space about the size of a scrollbar on the side of the screen. The space is also above xmobar (the battery system tray icon is hidden behind it and I can't click it). XMonad weird space (since I can't post images) Is there some weird XMonad or Gnome option I'm missing? I don't even know where to begin to look.

• Bad FPS for smaller size (OpenGL ES with SDL)

  - by ber4444

  If you saw my other question, well, there is still a little problem: Click here to watch on youtube Basically, the frame rate is very bad on the actual device, where for some reason the animation is scaled (it looks like the left side on the video). It is quite fast on the simulator where it is not scaled (right side). For a test, I submitted this new changeset that hard-codes the smaller size (plus increases the point size for HII regions to make the dust clouds more visible), and as you see in the video, now it is slow even in the simulator (left side shows the small size, right side shows the original size -- otherwise the code is the same). I'm clueless why it's soooo slow with a smaller galaxy, in fact it should be FASTER. As for general speed optimization (which is not strictly part of my question but is closely related to it, esp. if we need a workaround to speed things up), some initial ideas: reducing the number of items drawn may affect the appearance negatively but screen resolution could be reduced there are too many glBegin(GL_POINTS)/glEnd() blocks, we could draw more than just a single star at once

• 12.04: Having problem with REISUB

  - by Jerry-bliss

  Often my ubuntu freezes up altogether(only able to move my cursor). So i try to reboot using the keys "ALT+PrntScrn+REISUB", but this is what happens Once i finish hitting the keys RE, my screen goes BLACK and it shows up a few lines of commands (or whatever) which I dont understand. I have no other choice other than manually force shut down (by pressing power button for 3-4 seconds) Here is a screenshot of what my black screen displays as soon as I hit R,E What do these lines mean? Is there anyway I can safely restart my PC? (Since i was unable to use printscreen, i had to manually take a snap of my monitor using my camera. I had taken 3 pictures of the same screen, because I could not capture the entire text displayed on my screen in a single click)

• Should "closed as duplicate" software programming be extreme or functional? [migrated]

  - by Web Developer

  I'm a web developer loving this site for it's potential, and it's Coffee look . I was reading a great question, that is this: click here and noticed 8 moderators tagged it as DUPLICATED! The question was closed! Obviously it isn't and I'm going to explain why if needed but it can be seen: the question is unique, is the case/story of a young who have SPECIFIC experience with C++ , VB and Assembler and asking, knowing this specifications an answer (It is not a general question like "hey I'm young can I do the programmer??") Let me know your opinion! do you think this question should or should not be closed? And let's think about also the people not only the "data" and "cases covered" ... do you think this is important too? or is better to keep a place where people doesn't count?

• Where do I have to paste an "xinput" command so that it executes it when GNOME is started?

  - by michuk

  On my Thinkpad I need to execute something like this in the terminal: xinput set-int-prop "TPPS/2 IBM TrackPoint" "Evdev Middle Button Emulation" 8 1 so that my the 2 buttons on my touchpad emulate the middle mouse click. Now I need this line to be executed each time I start GNOMe or X or whatever, so that it "just works". I tried ~/.xsession or ~/.bashrc but to no avail. Should I put it in GNOME start scripts or in /etc/X somewhere? I'm using Ubuntu 11.10.

• Package Manager Console For More Than Managing Packages

  - by Steve Michelotti

  Like most developers, I prefer to not have to pick up the mouse if I don’t have to. I use the Executor launcher for almost everything so it’s extremely rare for me to ever click the “Start” button in Windows. I also use shortcuts keys when I can so I don’t have to pick up the mouse. By now most people know that the Package Manager Console that comes with NuGet is PowerShell embedded inside of Visual Studio. It is based on its PowerConsole predecessor which was the first (that I’m aware of) to embed PowerShell inside of Visual Studio and give access to the Visual Studio automation DTE object. It does this through an inherent $dte variable that is automatically available and ready for use. This variable is also available inside of the NuGet Package Manager console. Adding a new class file to a Visual Studio project is one of those mundane tasks that should be easier. First I have to pick up the mouse. Then I have to right-click where I want it file to go and select “Add –> New Item…” or “Add –> Class…”   If you know the Ctrl+Shift+A shortcut, then you can avoid the mouse for adding a new item but you have to manually assign a shortcut for adding a new class. At this point it pops up a dialog just so I can enter the name of the class I want. Since this is one of the most common tasks developers do, I figure there has to be an easier way and a way that avoids picking up the mouse and popping up dialogs. This is where your embedded PowerShell prompt in Visual Studio comes in. The first thing you should do is to assign a keyboard shortcut so that you can get a PowerShell prompt (i.e., the Package Manager console) quickly without ever picking up the mouse. I assign “Ctrl+P, Ctrl+M” because “P + M” stands for “Package Manager” so it is easy to remember:   At this point I can type this command to add a new class: PM> $dte.ItemOperations.AddNewItem("Code\Class", "Foo.cs") which will result in the class being added: At this point I’ve satisfied my original goal of not having to pick up a mouse and not having the “Add New Item” dialog pop up. However, having to remember that $dte method call is not very user-friendly at all. The best thing to do is to make this a re-usable function that always loads when Visual Studio starts up. There is a $profile variable that you can use to figure out where that location is for your machine: PM> $profile C:\Users\steve.michelotti\Documents\WindowsPowerShell\NuGet_profile.ps1 If the NuGet_profile.ps1 file does not already exist, you can just create it yourself and place it in the directory. Now you can put a function inside like this: 1: function addClass($className) 2: { 3: if ($className.EndsWith(".cs") -eq $false) { 4: $className = $className + ".cs" 5: } 6: 7: $dte.ItemOperations.AddNewItem("Code\Class", $className) 8: } Since it’s in the NuGet_profile.ps1 file, this function will automatically always be available for me after starting Visual Studio. Now I can simply do this: PM> addClass Foo At this point, we have a *very* nice developer experience. All I did to add a new class was: “Ctrl-P, Ctrl-M”, then “addClass Foo”. No mouse, no pop up dialogs, no complex commands to remember. In fact, PowerShell gives you auto-completion as well. If I type “addc” followed by [TAB], then intellisense pops up: You can see my custom function appear in intellisense above. Now I can type the next letter “c” and [TAB] to auto-complete the command. And if that’s still too many key strokes for you, then you can create your own PowerShell custom alias for your function like this: PM> Set-Alias addc addClass PM> addc Foo While all this is very useful, I did run into some issues which prompted me to make even further customization. This command will add the new class file to the current active directory. Depending on your context, this may not be what you want. For example, by convention all view model objects go in the “Models” folder in an MVC project. So if the current document is in the Controllers folder, it will add your class to that folder which is not what you want. You want it to always add it to the “Models” folder if you are adding a new model in an MVC project. For this situation, I added a new function called “addModel” which looks like this: 1: function addModel($className) 2: { 3: if ($className.EndsWith(".cs") -eq $false) { 4: $className = $className + ".cs" 5: } 6: 7: $modelsDir = $dte.ActiveSolutionProjects[0].UniqueName.Replace(".csproj", "") + "\Models" 8: $dte.Windows.Item([EnvDTE.Constants]::vsWindowKindSolutionExplorer).Activate() 9: $dte.ActiveWindow.Object.GetItem($modelsDir).Select([EnvDTE.vsUISelectionType]::vsUISelectionTypeSelect) 10: $dte.ItemOperations.AddNewItem("Code\Class", $className) 11: } First I figure out the path to the Models directory on line #7. Then I activate the Solution Explorer window on line #8. Then I make sure the Models directory is selected so that my context is correct when I add the new class and it will be added to the Models directory as desired. These are just a couple of examples for things you can do with the PowerShell prompt that you have available in the Package Manager console. As developers we spend so much time in Visual Studio, why would you not customize it so that you can work in whatever way you want to work?! The next time you’re not happy about the way Visual Studio makes you do a particular task – automate it! The sky is the limit.

• Bug unsubscribing from Ubuntu One Mobile

  - by rhino

  Hi guys, I have an Ubuntu One Mobile subscription, which I can see in my subscriptions page: one.ubuntu.com/account/subscription/756082 I no longer need my Ubuntu One Mobile subscription, so click the link to cancel the Mobile service subscription: one.ubuntu.com/account/cancel/756082/ Then confirm that request to cancel: one.ubuntu.com/account/cancel/756082/confirm/ But the process ends there showing a "Something has gone wrong page", and my subscription remains active :( The same problem occurred when I attempted the same a few weeks back, so not a temporary problem I'm thinking. Any input gratefully received. I would like to report this problem directly to the maintainer of this part of the Ubuntu site but cannot see how to do that.

• What's New In 11.1.2.1 (Talleyrand SP1)

  - by russ.bishop

  This release is primarily about bug fixes and that's what we spent the most time on, but we also addressed a number of other things: 1. Performance improvements We've done a lot of work to improve the performance of page load and execution times. For example, the View Compare page is about half the size it was previously! We've also done a lot of work on the server to improve performance of queries, exports, action scripts, etc. We implemented some finer-grained locking so fewer operations will block other users while they are in progress. We made some optimizations to improve performance when you have a lot of network or database latency as well. Just a few examples: An Import that previously took 8 GB of memory and hours to complete now runs in about 30 minutes and never takes more than 1 GB of RAM. Searching by exact Node Name now completes within 2 seconds even for a hierarchy with millions of nodes. Another search that was taking 30 seconds to run now completes in less than 5 seconds. 2. Upgrade support This release supports automatic upgrade from previous releases, built right into the console. 3. Console Improvements The Console has been reorganized and made easier to use. It is also much more multi-threaded so it responds quicker without freezing up when you save changes or when it needs to get status. 4. Property Namespaces Properties now have a concept called a Namespace. This is tied into the Application Templates to prevent conflicts with duplicate property names. Right now, if you have an AccountType and you pull in the HFM template, it also has AccountType so you end up creating properties with decorations on the name like "Account Type (HFM)". This is no longer necessary. In addition, properties within a namespace must have unique labels but they can be duplicated across namespaces. So in the Property Grid when you click on the HFM category, you just see "AccountType". When you click on MyCategory, you see "AccountType", but they are different properties with different values. Within formulas, the names are still unique (eg: Custom.AccountType vs HFM.AccountType). I'll write more about this one later. 5. Single Sign On DRM now supports Single Sign-On via HSS. For example, if you are using Oracle's OAM as your SSO solution then you configure HSS to use OAM just like you would before. You also configure DRM to use HSS, again just like before. Then you configure OAM to protect the DRM web app, like you would any other website. However once you do those things, users are no longer prompted to enter their username/password. They simply get redirected to OAM if they don't already have a login token, otherwise they pick their application and sail right into DRM. You can also avoid having to pick an application (see the next item) 6. URL-based navigation You can now specify the application you want to log into via the URL. Combined with SSO and your Intranet, it becomes easy to provide links on our intranet portal that take users directly into a specific DRM application. We also support specifying the Version, Hierarchy, and Node. Again, this can be used on your internal portal, but the scenarios get even more interesting when you are using workflow like Oracle BPEL you can automatically generate links within emails that will take users directly to a specific node in the UI. 7. Job status and cancellation A lot of the jobs now report their status and support true cancellation. Action Scripts also report a progress complete percentage since the amount of work is known ahead of time. 8. Action Script Options Action scripts support Option declarations at the top of the file so a script can self-describe (when specified in the file, the corresponding item in the file is ignored). For example: Option|DetectDelimiter Option|UsePropertyNames|true This will tell DRM to automatically detect the delimiter (a pipe symbol in this case) and that all references to properties are by Name, not by Label. Note that when you load a script in the UI, if you use Labels we automatically try to match them up if they are unique. Any duplicates are indicated and you are presented with a choice to pick which property you actually referred to. This is somewhat similar to Version substitution, but tailored for properties. There are other more minor changes and like I said earlier a lot of bug fixes and performance improvements. Hopefully I will get a chance to dig into some of these things in future blog posts.

• How do I route my SMTP outgoing mail through gmail (Google Mail) ?

  - by Paula DiTallo

  Here is the quick answer:  Go into your client e software (e.g. Outlook, Thunderbird, etc.) for the account you are working on (usually default). Set the SMTP server to smtp.gmail.com Set the username as your gmail account user name (e.g. [email protected]). Gmail will need the username and password you use for that account, so if your default is set to some other email, be sure to set the username and password to that value, or click on the checkbox for username/password. Check TLS as the secure connection.   If you are looking for more in-depth info, check out Gina Trapani 's block on the topic.

• Command line method to find disk usage of camera mounted using gvfs

  - by Hamish Downer

  When my camera was mounted on /media I could use the standard tools (df) to see the disk usage of the card in my camera. However now the camera is mounted using gvfs, and df seems to ignore it. I've also tried pydf and discus to no avail. The camera is definitely available through nautilus, and when I select the camera in nautlius, the status bar tells me the amount of disk free. I can also open the ~/.gvfs/ folder in nautilus and right click on the camera folder and get the disk usage in a graphical way. But that is no use for a script. Are there command line tools that are the equivalent of df for gvfs filesystems? Or even better, a way to make df report on gvfs filesystems?

• Problems with opening CHM Help files from Network or Internet

  - by Rick Strahl

  As a publisher of a Help Creation tool called Html Help Help Builder, I’ve seen a lot of problems with help files that won't properly display actual topic content and displays an error message for topics instead. Here’s the scenario: You go ahead and happily build your fancy, schmanzy Help File for your application and deploy it to your customer. Or alternately you've created a help file and you let your customers download them off the Internet directly or in a zip file. The customer downloads the file, opens the zip file and copies the help file contained in the zip file to disk. She then opens the help file and finds the following unfortunate result:     The help file  comes up with all topics in the tree on the left, but a Navigation to the WebPage was cancelled or Operation Aborted error in the Help Viewer's content window whenever you try to open a topic. The CHM file obviously opened since the topic list is there, but the Help Viewer refuses to display the content. Looks like a broken help file, right? But it's not - it's merely a Windows security 'feature' that tries to be overly helpful in protecting you. The reason this happens is because files downloaded off the Internet - including ZIP files and CHM files contained in those zip files - are marked as as coming from the Internet and so can potentially be malicious, so do not get browsing rights on the local machine – they can’t access local Web content, which is exactly what help topics are. If you look at the URL of a help topic you see something like this:   mk:@MSITStore:C:\wwapps\wwIPStuff\wwipstuff.chm::/indexpage.htm which points at a special Microsoft Url Moniker that in turn points the CHM file and a relative path within that HTML help file. Try pasting a URL like this into Internet Explorer and you'll see the help topic pop up in your browser (along with a warning most likely). Although the URL looks weird this still equates to a call to the local computer zone, the same as if you had navigated to a local file in IE which by default is not allowed.  Unfortunately, unlike Internet Explorer where you have the option of clicking a security toolbar, the CHM viewer simply refuses to load the page and you get an error page as shown above. How to Fix This - Unblock the Help File There's a workaround that lets you explicitly 'unblock' a CHM help file. To do this: Open Windows Explorer Find your CHM file Right click and select Properties Click the Unblock button on the General tab Here's what the dialog looks like:   Clicking the Unblock button basically, tells Windows that you approve this Help File and allows topics to be viewed.   Is this insecure? Not unless you're running a really old Version of Windows (XP pre-SP1). In recent versions of Windows Internet Explorer pops up various security dialogs or fires script errors when potentially malicious operations are accessed (like loading Active Controls), so it's relatively safe to run local content in the CHM viewer. Since most help files don't contain script or only load script that runs pure JavaScript access web resources this works fine without issues. How to avoid this Problem As an application developer there's a simple solution around this problem: Always install your Help Files with an Installer. The above security warning pop up because Windows can't validate the source of the CHM file. However, if the help file is installed as part of an installation the installation and all files associated with that installation including the help file are trusted. A fully installed Help File of an application works just fine because it is trusted by Windows. Summary It's annoying as all hell that this sort of obtrusive marking is necessary, but it's admittedly a necessary evil because of Microsoft's use of the insecure Internet Explorer engine that drives the CHM Html Engine's topic viewer. Because help files are viewing local content and script is allowed to execute in CHM files there's potential for malicious code hiding in CHM files and the above precautions are supposed to avoid any issues. © Rick Strahl, West Wind Technologies, 2005-2012 Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();
