• Subversion error: (405 Method Not Allowed) in response to MKCOL

  - by Sergio del Amo

  I am getting the following error while trying to commit a new directory addition. svn: Commit failed (details follow): svn: Server sent unexpected return value (405 Method Not Allowed) in response to MKCOL request for '.... I have never seen this error before. How can I fix this problem? Solution I managed to solve the problem: Delete the parent's directory of the folder giving the problem. Do SVN Update. A folder with the same name as the new one already existed in repository. Delete this folder. SVN commit. Copy the new folder, schedule for addition and SVN commit.

• Remote server's x menus without vino, vnc etc

  - by Fredde

  A question where both google searches, as well as askubuntu and ubuntu forums searches fails though rephrasing the question a number of times. Have a Lubuntu server with some storage and functions and a lubuntu laptop. Previous when running winXP, I had Xming, could start a x-session on the server, got the lxpanel on the laptop, switching, running x-programs without a hitch though the lxpanel menu. A very neat and convenient solution. However the winXP crashed, me moving to lubuntu also for the laptop. still things work, I ssh into the server and can start x-programs without a hitch. But, as with all graphical desktops, I at times need access to the lx menus on the server to find programs and here the problems arise, most finding I got talk about installing VNC, vino etc overkills, avoiding existing X-integration between the servers. I'll like to do as I did with Xming, see the menu system on the server, in my "client's" xwin? Just to see the servers installed software without colliding with the laptop X-server, just using it as normal X-apps.

• The best way to learn how to extend Orchard

  - by Bertrand Le Roy

  We do have tutorials on the Orchard site, but we can't cover all topics, and recently I've found myself more and more responding to forum questions by pointing people to an existing module that was solving a similar problem to the one the question was about. I really like this way of learning by example and from the expertise of others. This is one of the reasons why we decided that modules would by default come in source code form that we compile dynamically. it makes them easy to understand and easier to modify for your own purposes. Hackability FTW! But how do you crack open a module and look at what's inside? You can do it in two different ways. First, you can just install the module from the gallery, directly from your Orchard instance's admin panel. Once you've done that, you can just look into your Modules directory under the web site. There is now a subfolder with the name of the new module that contains a csproj that you can open in Visual Studio or add to your Orchard solution. Second, you can simply download the package (it's NuGet) and rename it to a .zip extension. NuGet being based on Zip, this will open just fine in Windows Explorer: What you want to dig into is the Content/Modules/[NameOfTheModule] folder, which is where the actual code is. Thanks to Jason Gaylord for the idea for this post.

• The cable of my USB port hub is too short - what to do?

  - by Anna

  Hi, I just bought a new USB port hub "MSY USB 2.0 4-port hub". It has two inputs: A small USB entrance input for external power (?) The problem is that the cable that comes with the hub (small USB on one end, large USB on the other - to input into my computer), is too short for my needs. Is there a solution to this? buying a longer cable might be risky, I know that it might cause problems with power. Is there anything else I can do to make it work? Thanks.

• Bridging wireless and wired networks on Linux box

  - by nixnotwin

  I have the following setup: modem + router - - - - -Ubuntu box on master mode.........wireless devises. Ubuntu machine connects to Internet on wired network. I've dhcp3-server, masquerading, and wireless card with master mode on Ubuntu box. The issue is Ubuntu connects to the router on NAT. The wireless devises connect to the Ubuntu box on a NAT too (though different). SO my wireless devises are behind two NAT networks. The solution I am looking for is Ubuntu should forward dhcp requests to the modem+router, and Ubuntu should act as a switch or a bridge that allows wireless devises to connect to the wired network. So the modem+router should act a main router.

• Minutely cron, ensuring only a single instance

  - by Christopher Nadeau

  Is there a way to run a script every minute (or 2, or 5, etc), but only if it isn't already running? We have a set of scripts that need to run every minute. Sometimes they might start and finish in a second, other times they might go on for 5 minutes. Our current way of avoiding simultaneous executions is by setting a is_running flag in each script, and exiting if it's still enabled. But this is a little unreliable (i.e., fatal errors would cause the flag to remain enabled even after the script halted). We could write our own little manager, but I'm wondering if there is a more fashionable solution that already exists.

• Sending from alternative addresses in Exchange

  - by Sam Cogan

  One of the most frequent requests I get from users with Exchange, is to be able to send from one of their alternative email addresses, that is one of the addreses there account is configured with in Exchange, but that is not their primary address. Unfortuantely as far as I am aware Microsoft have not yet come up with a solution to this. I've used a number of hacks to get round this, sepearate accounts with POP3 access, Using the from field in outlook, but each have there draw back. What have you used in these situations to allow the use of these alternative addresses?

  Hi I am currently using three screens at the same time with my ATI 5770 & an active displayport converter. The thing is that the third screen ( the one that is using the active displayport converter ) is showing terrible resolution compared to my other two screens. ( Samsung syncmaster p23 ) two of my screens got a max resolution of 1920* 1090, meanwhile the third on is only capable of 1600 * 1200. Do any of u guys got any solution to this problem?

• Thinking skills to be a good programmer

  - by Paul

  I have been programming for last 15 years with non-CS degree. Main reason I got into programming was that I liked to learn new things and apply them to my work. And I was able to find and fix programming errors and their causes faster than others. But I never find myself a a guru or an expert, maybe due to my non-CS major. And when I saw great programmers, I observed they are very good, much better than me of course, at solving problems. One skill I found good in my mid-career is thinking of requirements and tasks in a reverse order and in abstract. In that way, I can see what is really required for me to do without detail and can quickly find parts of solution that already exist. So I wonder if there are other thinking skills to be a good programmer. I've followed Q&As below and actually read some of books recommended there. But I couldn't really pickup good methods directly applicable for my programming work. What non-programming books should a programmer read to help develop programming/thinking skills? Skills and habits to develop to be good at programming (I'm a newbie)

• Moving 2d camera in the y direction

  - by Alex

  I'm developing a simple game for the iphone and am struggling to work out the best way for the camera to follow the main character. The following picture hightlights the three main components: There are 3 components to this: Circle - the main character Green line - terrain Black background The terrain is simply made from an array of points (approx 20 points per screen width). The terrain is moved in the x direction relative to the black background in order to keep the circle in its position shown. The distance to move the terrain is simply: movex = circle.position.x - terrain.position.x with a constant to fix the circle at some distance from the left of the screen. I am struggling to determine the best way to position the terrain in the y plane keep the focus in the character. I want to move the terrain in the y direction smoothly and not fix it to the position of the circle, so the circle can move in the y plane. If I take the same approach as the x positioning, the character is fixed at a point on the screen and the terrain moves. I could sample some terrain points either side of the character and produce an average, but in my implementation this was not smooth. I thought another approach might be to create a camera 'line' that is a smooth version of the terrain line and make the camerea follow this, but I'm not sure if this is the optimum solution. Any advice is much appreciated!

• How do you make Windows 7 fully case-sensitive with respect to the filesystem?

  - by trusktr

  I want to make Windows 7 case-sensitive when it reads/writes anything on the hard drive (the C drive, or any other NTFS drive). I found a video via google that says to change the registry key HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\DontPrettyPath to a value of 1 (source). I also found a Windows support item that says something about modifying the registry key HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\kernel\obcaseinsensitive that leads me to assume putting a value of 0 will make Windows case-sensitive with NTFS filesystems (source). I have a feeling the second solution is the answer, but I'm not sure and I don't want to try it without being sure. Does anyone know for sure what is the correct way to make Windows 7 case-sensitive when it reads/writes to the C drive (and any other NTFS drive)?

• Samsung i780 networking problem

  - by Infinity

  Hello guys! Maybe this is not the right place to ask this, but I give a try for it. Please don't rate it down, just ignore it if you don't like. So I have a Samsung i780 mobile phone and I would like to use the internet through my wireless router. I have connected to it. I got an IP address. My laptop is also connected to the same wireless network and I can ping the mobile phone and I get answer. When I open the internet explorer and enter an address it says that it cannot connect to the internet. I have googled very much, but can't find the problem. What do you think, what is the solution?

• How to store 250TB of data and develop a backup/recovery plan?

  - by luccio

  I'm really new to this topic, so big apology for stupid questions. I have a school project and I want to know how to store 250TB of data with life-cycle for 18 months. It means every record is stored for 18 months and after this period of time can be deleted. There are 2 issues: store data backup data Due to amount of data I will probably need to combine data tapes and hard drives. I'd like to have "fast" access to 3 month old data, so ~42TB on disk. I really don't know what RAID should I use, or is here any better solution than combining disk and data tapes? Thanks for any advice, article, anything. I'm getting lost.

• Moving only the contents of a map and not the map itself on linux

  - by WebDevHobo

  Using the cp command, one can move files and folders on linux. I want to make a new user and move the contents of the skeleton map to their home directory. I use this command: cp -r /etc/skel/ /home/testuser/ However, this only creates a skel folder in testuser. The idea is that the contents of the /etc/skel folder be copied to /home/testuser, and not that a map be made in /home/testuser with those contents. I've checked the man page: Link, but nothing on there really seemed like the solution to me. Is there a way to do this, or do files really need to be moved manually, 1 by 1?

• What conventions or frameworks exist for MVVM in Perl?

  - by Will Sheppard

  We're using Catalyst to render lots of webforms in what will become a large application. I don't like the way all the form data is confusingly into a big hash in the Controller, before being passed to the template. It seems jumbled up and messy for the template. I'm sure there are real disadvantages that I haven't described properly... Are there? One solution is to just decide on a convention for the hash, e.g.: { defaults => { type => ['a', 'b', 'c'] }, input => { type => 'a' }, output => { message => "2 widgets found of type a", widgets => [ 'foo', 'bar' ] } } Another way is to store the page/form data as attributes in a class (a ViewModel?), and pass a whole object to the template, which it could use like this: <p class="message">[% model.message %]<p> [% FOREACH widget IN model.widgets %] Which way is more flexible for large applications? Are there any other solutions or existing Catalyst-compatible frameworks?

• I want to be a programmer, work in corporate environment, earn well, learn fast and eventually become a great programmer [on hold]

  - by Shin San

  I'll try to keep this simple: I'm 29, been dabbling with computers for the past 10 years, had entry level jobs in tech support for different apps, been fixing computers for a while and now want to specialize in something. I'm not 100% stranger to programming but haven't gone past if/then/else with anything. A bit of JavaScript, PHP, Python and currently checking out the "SELECT" statement in SQL :)) I'm curious about programming, I enjoy it and I'm thinking of making a living out of it. So, while I'm at it, why not earn a bit more than the average Joe? So, that's why I'm checking what the best solution, the best learning path and the most useful languages are considering: a) how easy/fast can you find a job by knowing it b) how much would I be able to earn c) how fast can I learn it By reading 10-20 articles online I've come up with an example, but I'm here for some expert advice. Example: * ratings from a) and b) point of view #1 sql ; #2 java ; #3 html (please don't start the markup language debate) ; #4 javascript From this ratings, I'd say a good way to go is learn html/css/(javascript or php) for the web part of apps, some SQL/MySQL/whateverSQL for holding data and loads of Java for the program itself. Please let me know if this is a good idea and if so, what should be the order for learning all of the above. Else, please let me know a better way and why it would be better. Many thanks for taking the time to read my question. Best wishes to you guys Edit: if I think Java + SQL + HTML&JavaScript is the way to go, does the order I'm learning them in matter? Or can I try to learn them all at once?

• reg delete gives me "access is denied" but regedit delete is ok

  I need to delete a key from a command line. So I wanted to use reg delete "the key to be deleted" /f but I get ERROR: access is denied. From the same login session (the same user) I am able to delete the key without any troubles from regedit.exe that is not run as administrator. I cannot use runas command to execute reg that I believe would be to solution because in fact I want to use reg to delete registry entry for administrator profile so runas works again.

• UNESCO, J-ISIS, and the JavaFX 2.2 WebView

  - by Geertjan

  J-ISIS, which is the newly developed Java version of the UNESCO generalized information storage and retrieval system for bibliographic information, continues to be under heavy development and code refactoring in its open source repository. Read more about J-ISIS and its NetBeans Platform basis here. Soon a new version will be available for testing and it would be cool to see the application in action at that time. Currently, it looks as follows, though note that the menu bar is under development and many menus you see there will be replaced or removed soon: About one aspect of the application, the browser, which you can see above, Jean-Claude Dauphin, its project lead, wrote me the following: The DJ-Native Swing JWebBrowser has been a nice solution for getting a Java Web Browser for most popular platforms. But the Java integration has always produced from time to time some strange behavior (like losing the focus on the other components after clicking on the Browser window, overlapping of windows, etc.), most probably because of mixing heavyweight and lightweight components and also because of our incompetency in solving the issues. Thus, recently we changed for the JavaFX 2.2 WebWiew. The integration with Java is fine and we have got rid of all the DJ-Native Swing problems. However, we have lost some features which were given for free with the native browsers such as downloading resources in different formats and opening them in the right application. This is a pretty cool step forward, i.e., the JavaFX integration. It also confirms for me something I've heard other people saying too: the JavaFX WebView component is a perfect low threshold entry point for Swing developers feeling their way into the world of JavaFX.

• Optimal Configuration for five 300 GB 15K SAS Drives

  - by Bob

  I recently acquired an HP Z800 workstation that has five 300 GB 15K SAS Drives. This system will be dedicated to running multiple virtual machines under VMware Workstation (Note: I'm not using ESXi because I do plan to use the system for other purposes.). For the host OS, I plan to install RHEL 5. My number one concern is guest performance. For example, should I create a RAID 10 array for the OS and virtual machine storage with four of the drives and reserve the 5th? Or, is there a solution that will provide better performance?

• Decorator not calling the decorated instance - alternative design needed

  - by Daniel Hilgarth

  Assume I have a simple interface for translating text (sample code in C#): public interface ITranslationService { string GetTranslation(string key, CultureInfo targetLanguage); // some other methods... } A first simple implementation of this interface already exists and simply goes to the database for every method call. Assuming a UI that is being translated at start up this results in one database call per control. To improve this, I want to add the following behavior: As soon as a request for one language comes in, fetch all translations from this language and cache them. All translation requests are served from the cache. I thought about implementing this new behavior as a decorator, because all other methods of that interface implemented by the decorater would simple delegate to the decorated instance. However, the implementation of GetTranslation wouldn't use GetTranslation of the decorated instance at all to get all translations of a certain language. It would fire its own query against the database. This breaks the decorator pattern, because every functionality provided by the decorated instance is simply skipped. This becomes a real problem if there are other decorators involved. My understanding is that a Decorator should be additive. In this case however, the decorator is replacing the behavior of the decorated instance. I can't really think of a nice solution for this - how would you solve it? Everything is allowed, even a complete re-design of ITranslationService itself.

• Pull row of data from one place in spreadsheet to another

  - by bookcasey

  I have a list of names and their assorted properties. I am trying to find a way to quickly move an entire row's worth of data into a different sheet so I can manipulate it. Currently I can accomplish this by copy and pasting the entire row, but this is not elegant nor dynamic (the number in blue does not update with this method): My ideal solution: A name is typed into the "Name" column. The spreadsheet program pulls the associated row from the "main" sheet into the new sheet. I am currently using Numbers.app, but am curious if this is possible in Excel, OpenOffice Calc, Google Docs, or any other spreadsheet program. Thank you.

• Restart my graphics card without rebooting?

  - by defaye

  Wondered if it is possible to use DevCon to restart a display device as a stop-gap solution to artifacts left over from a graphics card malfunction? In particular it leaves my cursor very un-user-friendly: I found out the hardware ID of my display adapter through device manager (below) [(windows key + pause break) - device manager - display adapters - right click your display adapter - properties - details - hardware ids.] I tried the commands (opened with admin privileges) devcon restart "PCI\VEN_1002" and devcon restart =display but it always come back with No devices restarted.. Is it even possible to restart the graphics card without a system reboot?
