  • What is the best objective way to measure language popularity trends? (What's better than TIOBE?)

    - by Eric Wilson
    The best way to get data on computer language popularity that I know is the TIOBE index. But everyone knows that TIOBE is hopelessly flawed. (If someone provides a link to support this, I'll add it here.) So is there any data on programming language popularity that is generally considered meaningful? The only other option I know is to look at the trends at indeed.com, which is inherently flawed, being based on job postings. It isn't like I would make a future language decision solely based on an index, but it might provide a useful balance to the skewed perspective one obtains by talking to ones friends and colleagues. To illustrate that bias, I'll point out that based on the experience of those I personally know, the only languages used professionally today (in order of popularity) are Java, C#, Groovy, JavaScript, Ruby, Objective C, and Perl. (Though it is evident that C, C++ and PHP were used in the past.) So my question is, everyone bashes TIOBE, but is there anything else? If so, can anyone explain how we know the alternative has better methodology? Thanks.

  • Windows XP SP3 dissapearing mapped drives

    - by Alan Spark
    I am running Windows XP Pro SP3 and I've got a few shares on my NAS that are mapped to reconnect automatically. I can access the drives soon after starting windows but after a period of inactivity I get the error "The local device name is already in use". This cannot be remedied until I restart the computer - I've tried disconnecting and re-mapping without success. This was working fine until I recently reinstalled Windows and I'm not sure what is going on. Any help would be greatly appreciated. Thanks, Alan

  • I screwed up, exit in .bashrc

    - by camel_space
    I put "exit" in my .bashrc file. I don't have physical access to the machine so to connect to it I use ssh. I don't have root privileges. Every time I connect to the server, the connection automatically closes. So far, I've tried: Overwriting .bashrc with scp and sftp. The connection closes before I can do anything. Using a few different GUI programs to access ssh (connection closes) Overwriting the file with ftp. (can't use ftp) From my home computer $ ssh host "bash --noprofile --norc" (connection closes) $ ssh host "mv .bashrc bashrc_temp" (connection closes) $ ssh host "rm .bashrc" (same thing) $ ssh host -t (connection closes) Is there anything I can do to disable .bashrc or maybe overwrite the file before .bashrc is sourced?

  • "Punch card" application

    - by icelava
    Our main-con manager is looking for a "punch card" type of attendance-logging application. We need to take attendance every day, and the most "automatic" method is simply to track when people unlock their Windows desktop screen (not logon, because many simply leave the computer on indefinitely), and report to a remote location/repository, where the administrator will be able to observe which users unlocked their screens each day. Has anybody come across such an application suite? It likely has to be a Windows service so that it operates regardless of who is logged into the system.

  • Open Directory authenticated bind succeeds, but creates incomplete record

    - by Jay Thompson
    I have about a dozen Macs running 10.6.7 or 10.6.8, which are all failing to bind properly to my new 10.7.4 Server OD. I can bind them just fine via Directory Utility or dsconfigldap, and it reports success. However, when I look at the record, it is failing to write the MAC address. Even if I manually update the record with the MAC address, MCX doesn't do anything and clients can't log in to OD accounts. All of the affected clients have hundreds of lines in the /Library/Logs/DirectoryService.error.log like so: 2012-09-15 22:23:18 EDT - T[0x00007FFF70292CC0] - GetMACAddress returned 0x *** bad control string *** 8x I do know that all of these clients were previously managed with the Guest computer account, and I also know that they were all imaged with a DeployStudio image when they were purchased. I've tried dscacheutil -flushcache, but after that I'm drawing a blank. Google has a few hits, but nothing very helpful. Re-imaging would be ideal but probably isn't going to happen. Anyone come across this before?

  • Ubuntu live cd : black screen and blinking cursor

    - by IFasel
    I try to install ubuntu 12.04 on my computer. I can get to the purple screen on the live cd but then, if I choose "Installing Ubuntu", I have a black screen with a cursor blinking (and nothing else happens). My PC : acer aspire M3920, CPU i5-2300, 8 Gb RAM, NVIDIA gt 405. What I already tried : I tried with 12.04 and 13.04 daily build I tried with a live usb and with a live dvd I tried the following boot options : nomodset, acpi=off I googled a lot and it seems that it could be a graphic card problem. Do you know any other boot options that I could try ? UPDATE This is not a duplicate : I've tried all the common boot options (nomodeset, noacpi...) and it doesn't change anything. With the option "no splash" (instead of "quiet splash"), I can see what happens before the forever-blinking cursor : [sdg] no caching mode present [sdg] assuming drive cache : write trough ata8.00: excetion Emask 0x52 ... frozen ata8 : SError : { RecovData RecovComm UnrecovData...} ata8.00 : failed command : IDENTIFY PACKET DEVICE ... ata8.00 : status : { DRDY } ata8 : hard resetting link Does somebody know what it means ? N.B. astonishingly, Puppy Linux boots fine (but Debian, Fedora and Ubuntu do not) Solution In fact, it was not a graphic card problem. I had to disconnect the dvd drive and connect it to another free sata connector (I don't really understand why Ubuntu had trouble with this connector and Windows 7 not). After that, everything worked fine.

  • Unity no longer loads in 13.04 for main user

    - by user152973
    When Ubuntu starts up, Unity fails to load (I can only see my desktop with no unity sidebar and no system bar in the top right). I tried the advice of Unity does not start in Ubuntu 13.04 which recommended the following commands: dconf reset -f /org/compiz/ unity --reset-icons &disown I ran the commands without errors an restarted the computer, but the problem persists. I am currently running Gnome. I have looked at other pages from the Google search "ubuntu unity failed to load 13.04", but the advice was similar to above and seems to be concerned with a system upgrade in April 18, 2013. I suspect my issue is something far more recent. Please give me advice on how to restore Unity on my account or at least figure out what the problem is. Thank you. Some information that might be relevant: -Unity has worked fine on 13.04 for the 6 months that I've had it until today. (November 10, 2013) -I have set up the update tool to automatically update when available. It is very possible that the system applied some updates without my knowledge. -Interestingly, Unity works fine on the Guest account. -I have made it so the system automatically logs me in at start-up. -This is a personal laptop. No one else has access to it. -I was not doing anything with the system settings or the terminal and have not installed any new software for the past 3 days. -I am running the System76 native Linux laptop Ultra Lemur. I did not contact their support yet because it seemed unlikely that this is a System76-specific error.

  • How do I get the machine name from an IP via Multicast DNS?

    - by Adam
    I have a list of IP addresses on a network, and most of them support multicast DNS. I'd like to be able to resolve the server name instead of just having the IP address. ping computer.local 64 bytes from 192.168.0.52: icmp_seq=1 ttl=64 time=5.510 ms 64 bytes from 192.168.0.52: icmp_seq=2 ttl=64 time=5.396 ms 64 bytes from 192.168.0.52: icmp_seq=3 ttl=64 time=5.273 ms Works, but I'd like to be able to determine that name from the IP. Also the devices don't necessarily broadcast any services, but definitely do support mDNS broadcast. So looking through services won't work.

  • How to optimize a box2d simulation in action game?

    - by nathan
    I'm working on an action game and i use box2d for physics. The game use a tiled map. I have different types of body: Static ones used for tiles Dynamic ones for player and enemies Actually i tested my game with ~150 bodies and i have a 60fps constantly on my computer but not on my mobile (android). The FPS drop as the number of body increase. After having profiled the android application, i saw that the World.step took around 8ms in CPU time to execute. Here are few things to note: Not all the world is visible on screen, i use a scrolling system Enemies are constantly moving toward the player so there is alaways to force applied to their body Enemies need to collide between each others Enemies collide with tiles I also now that i can active/desactive or sleep/awake bodies. Considering the fact that only a part of the enemies are possibly displayed on screen, is there any optimizations i can do to reduce the execution time of box2d simulation? I found a guy trying an optimization based on distance of enemies from the player (link). But i seems like he just desactives far bodies (in my case, i could desactive bodies that are not visible). But my enemies need to move even when they are not visible on screen, and applying forces will not workd on inactive bodies. Should i play with sleeping bodies here? Also, enemies are composed by two fixtures and are constantly colliding with each others and with tiles but i really never need to get notified about that. Is there anything i can do to optimize this kind of scenario? Finally, am i wrong to try to run simulation at 60FPS on mobile and should i try to make it run at 30FPS?

  • Mysterious "media" volume mounted on desktop Mac OS X

    - by Allen
    I have a mysterious volume mounted on my desktop that I can't seem to forcibly unmount. I've tried using umount and also diskutil, but it seems to automatically remount itself. I've copied my hdd with Time Machine, and copied it onto a new computer, and it also has the drive mounted on it. It's not pointing to anything and I can't open it, nor can I forcibily remove it by hand with rm -Rf. Any ideas? I noticed this problem after I upgraded to Mountain Lion from Lion. It causes problems because when I try to select a file using the built in Finder dialog box, it freezes for a few minutes because it tries to cache or read into the "media" mounted volume.

  • Launching multiple applications with a single command/script/shortcut

    - by Bill
    I realized a few days ago that every time I sit down at work, I do a few things after unlocking my computer. First, I open up Firefox, then I open up Chrome, then I log in to Digsby. I realized I could probably save repeating this daily by writing a small batch script to open up Firefox and Chrome , but I couldn't figure out how to make it work.. and since the whole effort is to save time I don't want to bash my head around in the windows command prompt to do it. I also tired this in powershell but ran in to a bunch of security nonsense. Is there a way to do this that I am missing? Bonus points if somebody has figured out how to manipulate Digsby via COM , scripting, or python =)

  • Why is my USB data transfer so slow?

    - by Dave M G
    Whenever I do any kind of file transfer using USB, whether to a USB stick, or with my Android phone, or anything else, it is ridiculously slow. It says 59.8 KB/sec, which would be an awesome speed if this were 1991 and I was using a modem to dial up to my local BBS. Surely USB technology is better than that...? 37 seconds to move less data than the equivelent of 1 MP3 file? Also, regardless of what it says about speed and time, the reality is much, much slower. I routinely see it say something like "37 seconds left" and have to wait for minutes. Sometimes, if I want to move large amounts of files, it can say it will take 8 hours or more. Is this normal? My computer may not be the most awesome on the market, and about a year old, but it's an i5 with 4GB RAM and modern components, so surely this isn't the hardware's fault. What can I do to get better USB data transfer performance? Also, I did look at this question, but my newbie eyes don't see anything that look like an actual solution, just a lot of discussion about what transfer rates could or should be. Update: As requested in the comments, I've generated a whole bunch of output from the command line, and put it on Ubuntu Pastebin. Please see it here.

  • preloading RSS contents in thunderbird, before actually reading them

    - by Berry Tsakala
    i have thunderbird 3.x, and i'm subscribed to several RSS feeds. How can I tell thunderbird to load/download any new RSS items in the background? The usual behavior with RSS feeds is that it download the headrs, or few introductory lines from the contents, but only when i'm clicking a feed item it starts loading "for real". I really want to receive the feeds and not to wait for them to load, the same way i receive emails in any email client - all messages are fully downloaded at once. there could be several reasons, BTW. - e.g. if i have short connection time, i'd rather connect, sync everything at once, and read it later. - or if i have a slow wifi connection, it's annoying to wait for each and every message, but the computer is idle while reading.. thanks

  • Manually forcing TCP connection to retry

    - by Vi
    I have a TCP connection (SSH session to some computer for example) Network suddenly goes down and drops all packets (disconnected cable, out of range). TCP resends packets again and again, retrying with increasing delays. I see the problem and plug the cable back (or restore network somehow). TCP connection finally successfully resends some packet and continues. The problem is that I need to wait for a some timeout on point 5. I want to use my opened SSH session now and not wait for 5-10 seconds until it finds out that connection is working again. How to force all TCP connections to resend data without now in GNU/Linux?

  • $DISPLAY dependent gtk themes

    - by Vlad Seghete
    I have a computer at home that I log into remotely. The "monitor" for it is a TV, so I want gtk applications to use a large font and icon theme, which I managed to do by editing the ~/.gtkrc-2.0 file and some other similar stuff. What I want to be able to do is have a separate theme for when I'm logging in remotely. The best way to explain is that I would like my gtk theme choice to be dependent on the X display that the application is started on. For example, if I start something on :0.0 then that is the TV and I want large fonts, but if I start it on localhost:10.0 I want to use a regular size font, because it will get rendered on my laptop screen. The elegant solution would be to have some sort of IF statement in the .gtkrc-2.0 file that checks the $DISPLAY variable and behaves accordingly. The problem is I can't find any documentation on control structures in .gktrc files, or if it's even possible to do that.

  • Recover data from SD card

    - by Paul Tarjan
    I have a 2GB kingston microSD card which is about 3 years old. I put it in a reader today in my Windows Vista computer, wrote a 32MB file onto it, safely removed it, and then tried to read it elsewhere. Nothing. Putting it back in vista it now says You need to format the disk in drive F: before you can use it. What should I do? I have access to many computers and OSes if your recommendations need that. I would be very sad if I lost all the contents of the card. Most of the data is backed up, but there are a few things that aren't. :( Doing a # dd if=/dev/sdg of=~/tmp/sd.bin gives me a 2 gig file, and grepping the file it seems like lots of my data is still there, how can I put it back together?

  • Looking for a way execute a task on all files in a directory (recursively) on Windows

    - by stzzz1
    I have a huge number of mp4 video files that needs to have a volume boost. I need a way to execute a ffmpeg audio filter on all files in a specified base directory (and in subdirectories as well). My problem is that I'm working on a Windows computer and I have no knowledge of its shell syntax. I would like to do the equivalent of what this bash script does : TARGET_FILES=$(find /path/to/dir -type f -name *.mp4) for f in $TARGET_FILES do ffmpeg -i $f -af 'volume=4.0' output.$f done I spent quite some time this afternoon looking for a solution but the recursive nature of what I need (that is so simple with find!) isn't too clear. Any help would be greatly appreciated!

  • is it okay to use random URLs instead of passwords?

    - by stew
    Is it considered "safe" to use URL constructed from random characters like this? http://example.com/EU3uc654/Photos I'd like to put some files/picture galleries on a webserver that are only to be accessed by a small group of users. My main concern is that the files should not get picked up by search-engines or curious power-users that poke around my site. I've set up an .htaccess file, just to notice that clicking on http://user:pass@url/ links doesn't work well with some browsers/email clients, prompting dialogs and warnings messages that confuse my not-too-computer-savy users.

  • Need guidelines for studying Game Development

    - by ShutterBug
    Hello Everyone, I've completed my graduation in Computer Science and currently working as a Software Engineer in a software company. I was wondering if I can build my career in Game Development. If so, what should be my approach. I've a few questions: Which universities to apply for masters? Preferably in Canada. Scholarships available? How shall I prepare myself before applying which shall give me an edge or advantage over others? I know Java, C#, PHP etc. I dont think these languages will be needed in Game Development. In that case, what languages shall I focus on from now? How do I get some ideas about IDE/Engines/Platform of game development? I'm not talking about flash/browser games. Please suggest me anything you want as I don't know much about it so I'm most likely to miss the most important questions. Feel free to make this thread a starter guide for those interested in perusing their career in game development. Post every relevant information. Thanks in Advance. EDIT: I can see a lot of people suggested to build a small project/game. If so, please suggest me how do I start a small game developing (maybe a clone to some existing small games ie pacman, brick game etc) from start to end.

  • Online backup service _with_ filtering (by extension, size and so...)

    - by QyRoN
    Hello, I recentely discovered an ability to backup personal data to online server but I was never surprised when I didn't found a popular service provides filtering capabilities, i.e. all of them they backup all the contents of specific folder. Are there any free options with filtering? To be specific, I need following features: Backup to online server. Automatic but bandwidth-transparent backup, i.e. it will backup my files automatically but won't try to do it if I'm heavily using the computer or internet at the moment. Individual filtering settings for folders, i.e. I want to specify which files to backup in every folder. Some free plan (since I'm not going to use more than 500MB of space).

  • Boot camp install from a HDD image

    - by Dombou
    How would one go about imaging an old work computer (old IBM aptiva from 2001ish) with Windows XP and lots of stuff (VPN client with settings etc) to a new iMac, while preserving Mac OSX? I can't simply install XP on the iMac and then reinstall/copy across stuff; it NEEDS to be an image. Can you even image smaller HDD's and then place them on large ones, or do they have to be the same size? Recommendations on how I go about this? Edit: It MUST be boot camp. I don't want to virtualize it from within OsX

  • Dual displays not working - NVidia - Ubuntu 12.04 - Second Monitor - Two Screens

    - by user75105
    Graphics Card: NVidia 460 GTX. Driver: NVIDIA accelerated graphics driver (version current) I have one DVI monitor, an old Dell LCD from 2005, and one VGA monitor, an Asus ML238H from 2010 whose HDMI port broke. The Asus is plugged into my graphics card's primary monitor slot and is the better monitor even though it is VGA but my computer defaults to the Dell. This happens when I boot as well; the loading screens, the motherboard brand image, etc. are all displayed on the Dell monitor until Windows loads. Then both monitors work. The same thing happened when I booted up Ubuntu 12.04 but I did not see the second monitor when the log-in screen popped up, nor did I when I logged in. I went to System Settings/Displays and my Asus monitor is not an option. I clicked Detect Displays and the Asus is not detected. I looked at the other questions regarding NVIDIA drivers and recalled my problems with Ubuntu a few years ago and decided to check the driver. I went to Additional Drivers to install the proprietary driver and it looks like it's installed and active but I'm still having this problem. There is another driver option, the post-release NVIDIA driver, but that does not fix the problem either. Also, under System Details/Graphics the graphics device is listed as Unknown, which might indicate that it is using an open source generic driver and not the proprietary NVidia driver. But under Additional Drivers it says that I am using the NVidia driver. Any help is appreciated.

  • Unix Shell/SSH config to allow TCP port forwarding without showing a command prompt

    - by Raphael K
    I'm running a Debian Linux. I'd like to have a user account that is able to connect via SSH for TCP-forwarding only, without a command prompt. e.g the following would work (from a remote computer): ssh -D1234 user@myhost but no command prompt would appear. Using a shell like /bin/false or /sbin/nologin is too restrictive as it doesn't even allow the user to log in. A shell that only allows the "exit" or Ctrl+D commands would do the job. I know that something similar is possible to allow only SFTP, but I can't find the equivalent for TCP forwarding. Thanks
