  • Is there a way to identify the device data is being received from? (python)

    - by Ed Prince
    Summary I have an MT4000 device connected to my computer using the serial port ttyS0. This is broadcasting data which is being received and read by a udp listener written in Python. I am also sending data manually through the terminal using a bash script I wrote. The Goal Is it possible to identify the device being used? The aim is for a web-page to allow the user to select which device they wish to see the data being sent. I would rather achieve this by directly identifying the device rather than saying anything from ttyS0, in case a different device is plugged in on that port. The Answer Is this possible, and if so, how? Everything I have found so far, is on identifying through a specific port.

  • VLC without chrome in Windows

    - by timberwo7ves
    I'm trying to run VLC (2.1, 64 bit) without any chrome on Windows 7. You can achieve it by going to Preferences, and in the Interface tab, unchecking Integrate video in interface, and also in the Video tab, unchecking Window decorations. The problem lies in the fact that without Window decorations there is no apparent way to move or resize the video window - in GOM player, for example, you can move window by dragging on the video itself; is there an option for this in VLC? Ideally, I would like to move the window by the method described above (by dragging the video), and would like the Window decorations to reappear on mouseover, to allow resizing; I'm a new VLC user, but unsure how far the customisation goes. - I'd settle with just the moving of the window via dragging the video if this is possible by advanced setting. There is a similar question here, but not exactly, and no solution to that particular question.

  • Kill xserver from command line (init 3/5 does not work)

    - by John Smith
    Hi, I'm running Linux Mint 10, although I've had this same issue with other variants of Linux. I've been told/found while researching that if the X server hangs or otherwise errors, one can drop to a root prompt, usually at another tty, and execute init 3 (to drop to single user mode) and then init 5 to return to the default, graphical session. Needless to say, I've tried this before in multiple configurations on multiple machines to no avail. The only feedback I receive form executing those two commands is a listing of VMWare services (from a kernel module) that are stopped and then restarted. Note: If I run startx (either before or after init 3), then I am told that the xserver is still running and that I should remove /tmp/.X0-lock. Having tried that, it removes that error message, but claims that the xserver cannot be attached as another instance is running. How do I kill the xserver completely? Can I killall some process name?

  • Mac OS X app window is too large - how can I resize?

    - by Kyle Cronin
    I'm a MacBook user, and when I'm home I plug into a large external monitor to get additional screen space. When I'm on the go I disconnect and use my laptop's built-in display. For the most part this arrangement works very well; however, I occasionally run into an issue where I'll resize an app on the external, causing it to be too large to fit on the built-in screen when I disconnect. Most apps don't have a problem decreasing their height automatically or resizing to fit when I click the green orb, but some (like iTunes) don't want to cooperate. How can I resize apps like iTunes without reconnecting to my external? Here's a screenshot:

  • Check if current Command Prompt was launched as the Administrator

    - by Canadian Luke
    I am looking to write a script that takes user input, then makes system wide changes. I need this to be very generic, but simply put, at the top, I need it to check to see if it's being run 'As an Administrator'. If it's not, then I want to display a message to tell them that; if it is, I want it to continue on. Is there a constant way to verify this? I am not looking to start a new session as the Administrator, I just want to detect if it's currently run as admin

  • Minimizing windows to tray in xfce

    - by Gryllida
    For XFCE (v. 4.8), I'm searching for possible options to minimize windows to tray (iconify). This means that 1) they're not in the window listing and 2) they're not in the alt+TAB menu and 3) when closed, the window hides (it disappears from window listing but still stays running). "alltray" has some weird GTK-related bug (https://bugs.launchpad.net/alltray/+bug/589831; windows hide but unhiding doesn't do anything; they stay in the tray icon until the user undocks them). "trayer" complains that "another systray is already running" and there's no obvious workaround. This question here is to ask about possible minimalistic (as everything in XFCE is) solutions which don't involve manual compiling, and aren't an overkill like cairo-dock is (a rather bloated gnome-style application which creates a new large 'tray' instead of using the existing one). Thanks!

  • Thunderbird: Synchronize tags

    - by fuenfundachtzig
    When I check my mail (via IMAP) on my laptop I'd like to see the same tags that I set when I checked my mail on my office computer. So the question is: Is it possible to synchronize user-specified mail tags between Thunderbird running on different computers? I've read that tags could be stored via IMAP on the server, so maybe it's just that the server of my mail provider does not support this IMAP feature? (Whichever it is...) Has anybody any experience with this? Related, but not my primary concern: Will there ever be a more flexible tagging system in Thunderbird which allows for an easier definition of new tags? (I.e. that a don't have to define new tags in the preferences menu, but can just type them in when reading a mail?)

  • Why is a SUBST'd drive inaccessible via shortcut or Run menu, but works fine from My Computer?

    - by Kev
    I have shortcuts to C:, D:, and E: in my quick launch bar. C and E work fine when I click on them, but D does nothing (that I can see) when I click on it. D and E are both SUBST'd drives pointing to folders that happen to be network shares. (I do this rather than mapping them so it doesn't have to go through the network layer--that way it works faster and I still get recycle bin functionality, etc.) If I go Start-Run and type D: or D:\, I get an error box saying This file does not have a program associated with it for performing this action. Create an association in the Folder Options control panel. If I go to My Computer and double-click the D drive, it comes up fine. Also, if I type \\servername\sharename pointing to the same place, it comes up fine. This just started happening this morning, out of the blue. It has been working fine ever since I set it up. Why might this be?

  • How can I setup a group writeable directory?

    - by meder
    $ whoami meder $ cd /var/www $ sudo mkdir html $ sudo groupadd web $ sudo usermod -a -G web meder $ sudo usermod -a -G web medertest $ sudo chown meder:web html $ sudo chmod -R g+rwx html The problem is, anytime I create a new file in /var/www/html even though the group is set to web, it is only writeable by the original user. I was given the advice of setting the umask to be 002 because the default is what causes the problems. But I would have to do this for all users in that group, and as far as I know it would be tedious having all of them modify ~/.bashrc to have umask 002. Even if I can do it myself with a shell command for all of those users, it still seems too tedious. Can anyone offer any advice on having a group writeable directory?

  • Mapped network drive connection timeout

    - by Terix
    I have server "Alpha" and server "Beta". Server Beta has a shared folder, that is mapped on server Alpha as "X:" On server Alpha there is a .vbs script that runs and take some files on local drive and copy them on X: drive. My issue is if no user log on server Alpha for a long time, it seems like the tcp connection underneath the mapped drive has a timeout, and the vbs script fails on the copy of file. As soon I log with remote desktop on Alpha server, the .vbs is successfull on the copy of the files. I have made many tests, using file logs to check what was happening and I found no way to refresh the connection and let the .vbs be able to copy files unattended.. I have always to log with remote desktop on Alpha server to refresh the connection and let the .vbs copy the files without issues. What can I do to avoid to log every time? The .vbs script runs 3 times a day and is very annoying. I do not have control over server Beta so I cannot change anything there, and I am very limited on changes I can do on server Alpha ( I cannot change registry and that sort of things)

  • How to repair damaged repository (which has a centralized .svn directory)?

    - by Heinrich Ulbricht
    I recently upgraded my TortoiseSVN installation to version 1.7.1. This forced me to upgrade my working copy as well. The upgrade removed all (but one) of the .svn directories from all subdirectories leaving only one in the root. Now out of the blue (of course; I suspect my antivirus software) there is an error when I for example try to clean up the working copy. I am also not able to commit anything. The error message when cleaning up is: Cleanup failed to process the following paths: C:\svn Can't open file 'C:\svn.svn\pristine\73\73bcc5fa7819f84f56b81dfa0236f0aac7b7d404.svn-base': The system cannot find the file specified. I traced the error to be related to the presence of one directory within the working copy. If I rename it then everything works. When it is present I get the error. I also deleted it and checked it out again. No change, the error persists. With previous versions I could repair damages in the .svn easily: just delete the offending folder and check out again. I cannot do this anymore because now the .svn dir is centralized. What could I do to repair my working copy?

  • A desktop Wiki editor/viewer: is there anything out there?

    - by MrBertie
    I'm a big user of wikis, mainly Dokuwiki, I really like the clarity and ease of use of simple text files. However all good wikis seem to require a web-server of some kind; has anyone come across a good desktop wiki editor/viewer that work with plain-text files, and allow me to work with wiki text files just like any other document file type (note: not a desktop wiki running inside a local webserver) Before you rush to suggest (I hope!) I have done months of research on this and have tried Wixi, Wikidpad, zulupad.... Any ideas anyone?

  • How do I make zeitgeist work in Arch?

    - by wleoncio
    I've been trying to setup Zeitgeist on my Gnome-shell system for a couple of days, but I'm yet to get it to work. I've done everything I could think of, i.e. installing zeitgeist from [extra], as well as libqzeitgeist. I've also installed all Gnome extensions created by Seif (https://extensions.gnome.org/accounts/profile/seif), since they're the reason I'm installing the package in the first place. I've tried running "zeitgeist-daemon --replace" and then "gnome-shell --replace", but nothing seems to work. According to Der Harm's wiki (https://wiki.archlinux.org/index.php/User:Der_harm#Gnome_Zeitgeist), the Zeitgeist daemon doesn't need to be explicitly started, but even if it was, I don't know how to do it (since it's not in /etc/rc.d, I bet adding "zeitgeist" to my rc.conf wouldn't do any good either). I can't believe there isn't a very simple setup here, please help me see what I'm missing!

  • installing SQLite3 gem on remote FreeBSD server using RVM - root permissions needed?

  • Are flash drives and hard drives thought of as "an ocean of bytes"?

    - by Jian Lin
    Why can a USB Flash drive be formatted as NTFS or FAT32? Is the USB Flash Drive and Hard Drive just to be thought of as "an ocean of bytes"? I get very used to hearing formatting a hard drive as FAT32 or NTFS, but we can also format a USB Flash drive as NTFS or FAT32? Is it because a hard drive or Flash drive both can be thought of as "an ocean of bits" or "an ocean of bytes"? I remember RAM as: it takes 16 bit or 32 bit as an address signal (the 16 or 32 copper footing on the circuit board), and give out 8 bit of data (the other 8 copper footing on the circuit board). So can a hard drive be thought of as working that way too? So that's why a Flash drive can be the same too? Just an "ocean of bytes". But is it true that hard drive's hardware make it an ocean of sector or something else, that is, the smaller unit of read / write is not byte but something else? So with this "ocean of bytes", NTFS has the format that says, "if the first byte is __, then it means __ (it is a file or folder, and link to which sector, indicated by byte 2 and 3, etc, etc)"

  • Windows 7: Search indexing is stuck

    - by Ricket
    When I open Indexing Options, it says: 4,317 items indexed Indexing in progress. Search results might not be complete during this time. It's stuck at 4,317 though; no more items have been indexed. Worst of all, SearchIndexer.exe is taking up 100% CPU (well, 50%, but I have a dual core CPU; it's taking up all processing power it can). It is not causing hard drive activity though. I tried clicking "Troubleshoot search and indexing" at the bottom of the Indexing Options window, but it couldn't find any problem. I've also tried the repair registry key that several websites suggest; I change HKLM\SOFTWARE\Microsoft\Windows Search SetupCompletedSuccessfully to 0 and restarted the computer, and it apparently repaired because it flipped back to 1, but the same problem continues to occur. It's reducing the battery life of my laptop and making it really hot so that my fans are running all the time. I've had to disable the Windows Search service. How can I fix this? Do I need to just flat-out reformat my computer? Update: I've tried rebuilding a couple times. There's nothing unusual about the locations I have to index, and I don't have any downloads in progress or anything like that. I don't see any reason why it stopped, and I noticed it much too late to do a system restore. At this point, I'm hoping someone will offer up some secret answer that will fix the problem, thus the bounty. Another update: I tried starting the service again, just to let it try yet again. It seemed okay at first (Indexing Options showed it operating at reduced speed due to user activity, and the number of files was going up). A while later I checked, and the service had stopped. Event viewer revealed some errors like this: Log Name: Application Source: Application Error Date: 2/1/2010 7:34:23 PM Event ID: 1000 Task Category: (100) Level: Error Keywords: Classic User: N/A Computer: ricky-win7 Description: Faulting application name: SearchIndexer.exe, version: 7.0.7600.16385, time stamp: 0x4a5bcdd0 Faulting module name: NLSData0007.dll, version: 6.1.7600.16385, time stamp: 0x4a5bda88 Exception code: 0xc0000005 Fault offset: 0x002141ba Faulting process id: 0x13a0 Faulting application start time: 0x01caa39f2a70ec02 Faulting application path: C:\Windows\system32\SearchIndexer.exe Faulting module path: C:\Windows\System32\NLSData0007.dll Report Id: b4f7a7ae-0f92-11df-87fc-e5d65d8794c2 Event Xml: <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event"> <System> <Provider Name="Application Error" /> <EventID Qualifiers="0">1000</EventID> <Level>2</Level> <Task>100</Task> <Keywords>0x80000000000000</Keywords> <TimeCreated SystemTime="2010-02-02T00:34:23.000000000Z" /> <EventRecordID>10689</EventRecordID> <Channel>Application</Channel> <Computer>ricky-win7</Computer> <Security /> </System> <EventData> <Data>SearchIndexer.exe</Data> <Data>7.0.7600.16385</Data> <Data>4a5bcdd0</Data> <Data>NLSData0007.dll</Data> <Data>6.1.7600.16385</Data> <Data>4a5bda88</Data> <Data>c0000005</Data> <Data>002141ba</Data> <Data>13a0</Data> <Data>01caa39f2a70ec02</Data> <Data>C:\Windows\system32\SearchIndexer.exe</Data> <Data>C:\Windows\System32\NLSData0007.dll</Data> <Data>b4f7a7ae-0f92-11df-87fc-e5d65d8794c2</Data> </EventData> </Event> If you are having the same error and arrived here from a Google search, please comment or add an answer detailing your progress on this, if any...

  • GhostScript noob help - Breaking a multipage PDF file into many single page PS or EPS files.

    - by godzilla_g
    Hi, I'm trying to do the following with ghostscript: Turn one multipage PDF file (about 3,000 pages, 200mb file) into: One file per page of the PDF, and convert each (page/file) to EPS or PS (post script(preferably)). Example: hello.pdf (10 pages) would produce: hello1.ps (page 1 out of 10) hello2.ps hello3.ps ... hello10.ps How can I do this? I've been trying for 4 days, and can't figure it out. I have a script I've tried(won't work): Note: Windows(7) user here. gs -sDEVICE=epswrite -o documentname-%.eps documentname.pdf I also don't know how to navigate to the directory where my file resides (cannot figure that out, too). If you can, please show me how. A big thank you.

  • Office jukebox systems

    - by Jona
    We're looking for a good office jukebox solution where staff can select songs via a web interface to be played over the central set of speakers. Must haves: Web Interface RSS / easy to scrap display of currently playing songs Ability to play mp3s and manage an ordered playlist. Good cataloguing of media. Multiple OSs supported as clients - Windows, Mac, Fedora Linux (will probably be accomplished by virtue of a web interface). We have tried XBMC which worked well as a proof of concept however the web interface is just too immature and has too many bugs for a reliable multi-user solution. I believe the same will be true of boxee. Nice to have: Ability to play music videos onto a monitor Ability to listen to radio streams specifically Shoutcast and the BBC. Ability to run on Linux is a nice to have but windows solutions which worked well would certainly be considered. I am aware of question 61404 and don't believe this to be a duplicate due to the specific requirements.

  • Windows 7 upgrade advisor issue

    - by Groo
    I am preparing to migrate a pretty old XP machine to Windows 7. I ran the Windows 7 Upgrade Advisor and got a couple of smaller issues (low 512Mb RAM complaints and similar stuff). Apart from that, everything else was shown as compatible, including my old ATI Radeon 9550/X1050 card: ATI Radeon 9550/X1550 Series: This device is compatible with Windows 7. The thing that concerns me is that people around the web seem to be unable to actually find a Windows 7 driver for this card. Even the ATI web page states that this is a legacy device: If the user chooses to, they can install the ATI Catalyst Windows Vista graphics driver under Windows 7. [...] Using the ATI Catalyst Windows Vista driver under Windows 7 is not officially supported by AMD [...] Should I trust the Advisor and continue with the update? Does this mean Microsoft will provide at least a generic driver which will allow hardware acceleration with this card?

  • Detect damage done by virus

    - by user38471
    Hey, this morning after I went to college a virus infected my pc without any user interaction at my end. When I came home my computer was completely frozen and infected with lots of trojans. I have not typed anything important since returning so keys cannot be logged. However I want to know exactly when my computer crashed from the time of infection to see what could potentially be done remotely by a hacker. The virus my pc was diagonosed with was "fakespypro" http://www.microsoft.com/security/portal/Threat/Encyclopedia/Entry.aspx?Name=Win32%2fFakeSpypro on a fully updated windows 7 installation with firewall enabled. My computer was connected to an internal dorm room network, so probably that has had to do something with it. Any further information about how I could backtrace this virus infection or ways to discover what data might be stolen would be greatly appriciated.

  • Running a command line app with sudo and password automatically on OS X startup

    - by Designer023
    I need to run an app at startup/login on my mac. I want it to launch in the background and start doing it's work without interrupting me or me having to start it up because I invariably forget and then when I need it, it wasn't running! I have tried using AppleScript to tell Terminal to run it and type my password in, but it ends up opening multiple Terminal windows and not working. Ideally I need a script that I can just add to the user login items and it will run for me. The app has no way of taking a password argument either and it has a password as well as the sudo! I need a solution that can either be done as an applescript (which can be made into an executable) or i need a commandline script but I have no idea about them. This is the manual code I type $ sudo serverStatus password:123456 password:serverpass My AppleScript: tell application Terminal activate do shell script "sudo serverStatus" delay 5 do shell script "123456" delay 2 do shell script "serverpass" end tell

  • Change the white background in webpages to another color

    - by Bruce Connor
    I'm currently using a dark theme in firefox. It looks really nice, but many webpages use a plain white background. The resulting contrast is a little unpleasant and sometimes hurts the eye when I switch from a dark tab to a white tab. Is there a way to make firefox replace white backgrouns everywhere with some other color (light gray, for instance)? It could be a Stylish script, a userChrome.css hack, or anything that works (preferably as light as possible). To make myself clear: after I achieve my objective, the background color whenever I visit the super-user site should be light-grey instead of white, and the same should happen to any other site with a white background (google sites, tech crunch, etc). Is there a way to do that?
