• Recover data from OST file

  - by Daniel Hilgarth

  I need to recover some mails from a backed up OST file. Unfortunately, I deleted the corresponding IMAP mail account from Outlook. When I recreate the mail account and replace the created OST file with my backup I get the following error message: The file {path}.ost cannot be accessed because it has been configured for use with a different mailbox. How to solve this problem? Please don't suggest a OST to PST tool unless you know it works. I tried numerous of those tools from dubious looking websites and none worked. Please note: I am using Outlook 2013 Preview.

• Can I connect my ipod's earphones to my computer?

  - by user1361315

  My computer (recent model Dell z600) has 2 input devices on the front of the computer, 1 has an icon of headphones and the other is a Mic icon. When I plugin my earphones to the input device that has the headphones, and play some sound I don't hear anything from my earphones (sounds comes from built in speakers). I know when I plugin a USB headphone set, it switches over to those on but for some reason my earphones are not being picked up. Is it not compatible? Note: my earphones look similar to http://www.hdaccessory.com/catalog/reprearphone.jpg

• How can I improve the "smoothness" of a 2D side-scrolling iPhone game?

  - by MrDatabase

  I'm working on a relatively simple 2D side-scrolling iPhone game. The controls are tilt-based. I use OpenGL ES 1.1 for the graphics. The game state is updated at a rate of 30 Hz... And the drawing is updated at a rate of 30 fps (via NSTimer). The smoothness of the drawing is ok... But not quite as smooth as a game like iFighter. What can I do to improve the smoothness of the game? Here are the potential issues I've briefly considered: I'm varying the opacity of up to 15 "small" (20x20 pixels) textures at a time... Apparently varying the opacity in this manner can degrade drawing performance I'm rendering at only 30 fps (via NSTimer)... Perhaps 2D games like iFighter are rendered at a higher frame rate? Perhaps the game state could be updated at a faster rate? Note the acceleration vales are updated at 100 Hz... So I could potentially update part of the game state at 100 hz All of my textures are PNG24... Perhaps PNG8 would help (due to smaller size etc)

• VirtualBox cannot start a virtual machine on Windows 7

  - by Zan Lynx

  Note that this question is mostly so others can find this information. I ran into a problem recently with my Fedora-14 virtual machine running on a Windows-7 host with VirtualBox. VirtualBox could not start the Fedora virtual machine, but it could start a Ubuntu virtual server machine that was configured for 512 MB of RAM. The Fedora-14 machine was configured for 2 GB of RAM. The Fedora-14 machine had been working a week ago. What had I recently changed...? Answer to follow.

• webgame engine how does it works

  - by TWCrap

  Hy all, first off all, don't yell that i shouldn't start with it, i just want to know how that works... The thing is, how does the engine of an webgame works. A game like tribalwars, grepolis and forge of empires. How does that keeping alive work. I mean, a user is building an building, and quit the browser... The building is build even when the session of the user is expired. but the points of the user is updated when the building is finished... So how does that works. What do you guys think? do they have some kind of cronjob that is fired every second, and that walks throug the database, and search for finished buildings, and update's the stuff? or do you guys think that they do it difrent?!? I hope that i was clear. -NOTE- i don't need anny code, i'm just intrested in the progress behind the game... Greetingz Marc

• Weird behaviour/rendering of backspace in Terminal.app when SSHing into zsh using tmux/screen

  - by Nils Riedemann

  Hi there, I just stumbled upon a weird problem. When I SSH into my server (centos, zsh) and I type some stuff and hit backspace It looks like a space - but internally it really deleted the characters. ls -l a Note that the space between land a is actually when I hit backspace. When I now hit return ls -a gets executed. This is only in zsh, in bash it works fine. Hope anyone has an idea what this is all about and how to fix this. Update: Only happens when using tmux/screen

• Generating random tunnels

  - by IVlad

  What methods could we use to generate a random tunnel, similar to the one in this classic helicopter game? Other than that it should be smooth and allow you to navigate through it, while looking as natural as possible (not too symmetric but not overly distorted either), it should also: Most importantly - be infinite and allow me to control its thickness in time - make it narrower or wider as I see fit, when I see fit; Ideally, it should be possible to efficiently generate it with smooth curves, not rectangles as in the above game; I should be able to know in advance what its bounds are, so I can detect collisions and generate powerups inside the tunnel; Any other properties that let you have more control over it or offer optimization possibilities are welcome. Note: I'm not asking for which is best or what that game uses, which could spark extended discussion and would be subjective, I'm just asking for some methods that others know about or have used before or even think they might work. That is all, I can take it from there. Also asked on stackoverflow, where someone suggested I should ask here too. I think it fits in both places, since it's as much an algorithm question as it is a gamedev question, IMO.

• Why is Python used for high-performance/scientific computing (but Ruby isn't)?

  - by Cyclops

  There's a quote from a PyCon 2011 talk that goes: At least in our shop (Argonne National Laboratory) we have three accepted languages for scientific computing. In this order they are C/C++, Fortran in all its dialects, and Python. You’ll notice the absolute and total lack of Ruby, Perl, Java. It was in the more general context of high-performance computing. Granted the quote is only from one shop, but another question about languages for HPC, also lists Python as one to learn (and not Ruby). Now, I can understand C/C++ and Fortran being used in that problem-space (and Perl/Java not being used). But I'm surprised that there would be a major difference in Python and Ruby use for HPC, given that they are fairly similar. (Note - I'm a fan of Python, but have nothing against Ruby). Is there some specific reason why the one language took off? Is it about the libraries available? Some specific language features? The community? Or maybe just historical contigency, and it could have gone the other way?

• Sharepoint insists it knows the link to my UNC and won't let me remove hyperlink formatting

  - by ray023

  We have a file share at work (one I do not have the power to rename) and it contains a space in it: \\WorkFileShare\Visual Studio\SP1 I'm creating a Wiki Entry that informs users they can locate the VS2010 SP1 download on this Share. For some reason, SharePoint will highlight and hyperlink the UNC up to the space. (I've been dealing with this behavior for years in Outlook and I fix by putting focus on the character before the space and then hitting backspace to remove the formatting). Simple enough and SharePoint also removes the formatting when you backspace on the character before the space. However, as soon as I move away from the link, SharePoint goes right back to highlighting and hyperlinking what it thinks is the UNC. Naughty Sharepoint!! So does anyone have any idea how to clear the formatting? NOTE: Highlighting the text and clicking on the "Clear Format" icon does not work.

• During interviews, how do I gauge a company's respect for my position?

  - by Bluu

  I'm a web developer who previously joined a software company not knowing their value and respect went to big data analysis, not their website. Sure, they needed a public-facing website, but I eventually found that the most exciting, valued projects there went to data teams. Realizing this, members of the web team were picked off and switched teams, making it hard for those left behind to keep up the work load, and making us look bad. At times it seemed the company culture sneered at us, wondering, "What does that team even do here?" A friend of mine had the opposite problem at another software company. All he wanted to do was crunch big numbers. However he complained that the rest of the company wouldn't shut up about developing the usability of their website. Meanwhile his analytics team languished. I've also heard of salespeople getting love at a company, while engineering as a whole is undervalued, or vice versa. As for my story, if I could have known the company was like that, I might have avoided the job in the first place. So, before I join a new company, how do I gauge its actual respect for my programming role? For its other roles? I want to avoid companies that aren't serious about my particular focus in programming, or, perhaps bigger picture, companies that don't value everybody who works there. (Note I think gauging the company's attitude toward the basic needs of its programmers is covered by these related questions.)

• How can I disable the purple bootloader splash at boot?

  - by wim

  This question has been answered before, but neither of the methods in the accepted answer worked for me on 11.10. First I tried editing in /etc/default/grub, and then running sudo update-grub. But after that I still got a blank, plain, purple screen while the kernel is loading. The screen has no boot options, and it obscures those dmesg that I want to see going in the terminal. Next I tried removing the plymouth-theme-*, but that just broke my gnome-shell theme looks, and the purple screen still remains. I have also tried configuring it with startupmanager package, but nothing seems to get rid of that darned purple splash. here are the contents of my /etc/default/grub file: # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT="0" GRUB_HIDDEN_TIMEOUT="0" GRUB_HIDDEN_TIMEOUT_QUIET="true" GRUB_TIMEOUT="0" GRUB_DISTRIBUTOR="`lsb_release -i -s 2> /dev/null || echo Debian`" #GRUB_CMDLINE_LINUX_DEFAULT="" GRUB_CMDLINE_LINUX_DEFAULT="" GRUB_CMDLINE_LINUX="" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) # GRUB_TERMINAL="console" # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE="640x480" # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID="true" # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1" GRUB_DISABLE_OS_PROBER="true"

• Can only connect to IIS site through localhost

  - by Rembrandt Q. Einstein

  I'm building a web service for my company's iPhone application, and everything's been working smoothly by running tests through localhost on the development machine. I'm now in the phase where I need to test connections from other computers within the network, and any connection other than localhost gives me a 404. My internal IP, 127.0.0.1, and computername all get 404 when connecting from any computer, either the one the site's hosted on or any others on the network. Telnet can get through to port 80, and I've temporarily disabled all firewalls on this machine (I do not have control over the external firewall, but I'm only testing connections within the network) Does anyone have a clue why this is happening? I was able to connect to the web service from other computers when hosted on a Mac via Apache, but because I'm now using a SQL Server connection I'm restricted to using IIS for Windows Authentication. Googling only provided answers related to firewalls, and mine is disabled note: I cannot use Anonymous Authentication, but even in testing that it did not affect the issue.

• Can't get nmap to work under Windows 7 64 bit

  - by jitbit

  I'm trying to install and run the nmap tool to test my server, but it keeps saying Note: Host seems down. If it is really up, but blocking our ping probes, try -P0 and showing all the server ports are closed. Which is not true - the server is up and has lots of open ports. Any ideas? UPDATE: Just to clarify - the server can be pinged and port-scanned fine by other programs. It's juts nmap that does not work. Even "google.com" seems to be down for nmap.

• How are cached Windows credentials stored on the local machine?

  - by MDMarra

  How are cached Active Directory domain credentials stored on a Windows client? Are they stored in the local SAM database, thus making them susceptible to the same rainbow table attacks that local user accounts are susceptible to, or are they stored differently? Note, that I do realize that they are salted and hashed, so as not to be stored in plain-text, but are they hashed in the same way as local accounts and are they stored in the same location? I realize that at a minimum they're be susceptible to a brute force attack, but that's a much better situation than being vulnerable to rainbow tables in the event of a stolen machine.

• Can I use a wildcard to denote subdirectories as opposed to just files in the Windows Command Prompt

  - by Dinosaurus

  I know I can use a wildcard to list the files in a single directory: dir *.java However, does anyone know if it is possible to denote a subdirectory with a wildcard as well? I would like to do something like dir classes/*/*.java Where, it will list all the java files in every subdirectory beneath the classes directory. So, if there is: classes/cs1100/ classes/cs1200/ classes/cs1500/ It will list all the java files within these. Note, I'm not using this specifically for the "Dir" command, but instead another command line tool that accepts a list of files. But, if it works for Dir, it shoudl work in my other program as well.

• Do most front and rear USB connections deliver the same power and performance?

  - by Bratch

  I was reading this Three Monitors For Every User and there were some comments about rear USB ports being able to deliver more power than front USB ports because they are directly connected to the motherboard and closer to the power supply (by circuit board runs). Even though the front USB ports may have connectors farther from the power supply, and there are cables from the motherboard to the front ports, I think that the difference in power would be negligible (unless the case is over 5 meters long). Anyone know for sure if they are the same or different? Note that I'm not talking about an older case where the front might have been USB 1.1 and the rear USB 2.0. A modern case would have USB 2.0 on all ports. And of course using a powered hub would deliver plenty of power.

• How to run scripts within a telnet session?

  - by wenzi

  I want to connect to a remote host using telnet there is no username/password verification just telnet remotehost then I need to input some commands for initialization and then I need to repeat the following commands: cmd argument argument is read from a local file, in this file there are many lines, each line is a argument and after runing one "cmd argument", the remote host will output some results it may output a line with string "OK" or output many lines, one of which is with string "ERROR" and I need to do something according to the results. basically, the script is like: initialization_cmd #some initial comands while read line do cmd $line #here the remote host will output results, how can I put the results into a variable? # here I want to judge the results, like if $results contain "OK";then echo $line >>good_result_log else echo $line >> bad_result_log fi done < local_file the good_result_log and bad_result_log are local files is it possible or not? thanks! NOTE: I can't control B, I can only run initial cmds and cmd $line on B

• GVim Stop at end of line with arrows

  - by viking

  When using the arrow keys in Vim on Linux, they act the same way as h and l , stopping when the end of a line is reached. GVim on Windows doesn't do this, instead allowing the arrow keys continue past the end (or beginning) of a line and on to the next line. Is there any way to change the arrow key behaviour and cause them to stop at the end of a line like the character navigation keys? NOTE: I am not looking for a way to get to the beginning or end of a line, I realize that 0 and $ do this.

• Mac webcam photo application with access to camera settings (resolution, camera selection, color balance, focus)

  - by Pascal T.

  Does anyone know about a webcam photo application (ie an alternative to photo booth) with would allow to change the settings on the camera, such as : Select camera (I.e I want to use an external webcam) Change camera resolution (with photobooth change camera settings (I.e autofocus, aperture, color balance, etc..) I did a lot of research on the internet with no success. I am looking for a very simple app (such as wmcap.exe on Windows) What I tried so far: photo booth: it works with an external camera, however there is no way to change the resolution, or the color/focus settings manycam : a virtual webcam driver. you can add special effects to your camera and transfer those effects to any app, but not change your camera settings... iGlasses : enables you to change the camera settings inside photo booth and other apps. However you cannot control the focus, nor the video resolution macam (did not work on my Mac book Pro) Does anyone know better than me? Note : my only solution now is to launch a virtual machine (with parallels desktop) and take the pictures from there!

• how to fully unit test functions and their internal validation

  - by Patrick

  I am just now getting into formal unit testing and have come across an issue in testing separate internal parts of functions. I have created a base class of data manipulation (i.e.- moving files, chmodding file, etc) and in moveFile() I have multiple levels of validation to pinpoint when a moveFile() fails (i.e.- source file not readable, destination not writeable). I can't seem to figure out how to force a couple particular validations to fail while not tripping the previous validations. Example: I want the copying of a file to fail, but by the time I've gotten to the actual copying, I've checked for everything that can go wrong before copying. Code Snippit: (Bad code on the fifth line...) // if the change permissions is set, change the file permissions if($chmod !== null) { $mod_result = chmod($destination_directory.DIRECTORY_SEPARATOR.$new_filename, $chmod); if($mod_result === false || $source_directory.DIRECTORY_SEPARATOR.$source_filename == '/home/k...../file_chmod_failed.qif') { DataMan::logRawMessage('File permissions update failed on moveFile [ERR0009] - ['.$destination_directory.DIRECTORY_SEPARATOR.$new_filename.' - '.$chmod.']', sfLogger::ALERT); return array('success' => false, 'type' => 'Internal Server Error [ERR0009]'); } } So how do I simulate the copy failing. My stop-gap measure was to perform a validation on the filename being copied and if it's absolute path matched my testing file, force the failure. I know this is very bad to put testing code into the actual code that will be used to run on the production server but I'm not sure how else to do it. Note: I am on PHP 5.2, symfony, using lime_test(). EDIT I am testing the chmodding and ensuring that the array('success' = false, 'type' = ..) is returned

• Trac/SVN to DVCS Migration

  - by quanticle

  The project I'm currently working on is using Trac, with SVN integration. It's worked great until now. Now, however, we've taken on some additional developers and we're running into issues with branching and merging. Because of this, I think a move to a distributed version control system is in order. The problem is that Trac is very closely integrated with the SVN repository. We have tight integration between the tickets and the revision numbers of code changes corresponding to those tickets. In addition we have a support wiki that has a lot of data that helps the tech. support team. Is there a way we can migrate to git or mercurial without losing the benefits of Trac? I've looked at the git plugin for Trac, and I'm unsure of how well it works. Has anyone here used it with a project that's been migrated from SVN? EDIT: I should note that the most important priority for us is maintaining the links between Trac tickets and the corresponding changesets in SVN. That's a tool that we use every day, and it provides an easy way to jump to code changes when reviewing tickets. Wiki migration would be nice to have, but if it's not possible, we can continue to run the old system whilst we write some kind of a one-off script to migrate the content.

• Acrobat keyboard stealing in Firefox

  - by Uiy

  There are times when I open a pdf in firefox(which uses the acrobat plugin) and the "pdf" steals control of the keyboard. The arrow keys do not work in other programs. Well, If I hold them down they will then work but it becomes hard to navigate that way. It seems acrobat installs a global keyboard hook in some cases and takes control of the keyboard. This didn't start happening until recently(a few months ago). Note that it doesn't happen on all pdfs and everything returns to normal when the pdf is closed. This seems to be an issue with acrobat... maybe a setting? Anyone have any ideas what is going on?

• Tunneling over HTTP

  - by Morgan

  Hello, I have a network at work that is locked behind a firewall and Internet connection is available only by using a proxy server. At work, I can connect to databases that are distributed across the network. However, at home, I cannot connect to the proxy server or the databases. How can this be done? I can access my workstation via LogMeIn, so I can install anything on it. I thought of installing some kind of tunneling mechanism in my workstation. Then, at home, I could connect to this mechanism, which would in turn do the required connections. So essentially, what I'd like to do can be represented by the following diagram: Home = Workstation = Database. For example, whenever I connect to, say, 10.140.0.1:1234 at home, this would be redirected to 10.140.0.1:1234 of my Workstation, because 10.140.0.1:1234 is only available through the corporate network. NOTE: I'm using Windows XP.

• Load balancing + NAT issue on BNT GBE 2-7 gear

  - by Clément Game

  Hi guys, I've got troubles configuring an Hardware load-Balancer with NAT functions. I have the following architecture: Internet === VIP (public) LB (private ip) ==== private addressed servers When a connection is initialised from the outside (internet) , the LB correctly forwards the SYN packet to one of the private servers. But when these servers want to reply with a SYN/ACK there is a problem. the initial SYN packet had as ip header : VIP = Private_server_Address But the private servers cannot reach VIP from their side (this is normal since it's nated), and then provide a correct reply. Have you guys any solution to correctly forward the packets to their correct destination ? Note: The load balancer, which is the default gw for the servers, also has a NAT rule for "masquerading" (actually more SNAT than real masquerading) Regards, Clément.
