  • Is it possible for root to execute a command as non-root

    - by adnan kamili
    I am root user and suppose i want to run any application as another user. is it possible, without switching to another user. Something like # google-chrome user=abc I am actually executing a cli program as a non root user. I have set the sticky bit on and i am using setuid. So the program runs with root privileges. Now i am using system() with in the program to invoke gui app. But i dont want to run it as root. so i want to temporarily drop root privileges only for that call.

  • How would you shorten 5,000+ URLs? [closed]

    - by Tyler J Fisher
    How would you go about shortening approximately 5,000 permalinks? The links point to a remote media archiving server, and are unlikely to change. Example URLs: rtsp://foo-1.bar.com/xx/xx/xx/xx.rm http://media.foo.org/xx/xx/xx.mp4 The URLs are going to be stored in a local MySQL database, as such it's crucial that the URLs are in a manageable form (i.e bit.ly or ow.ly). There are bulk URL shortening services, but those only allow shortening of 100 links/day, which isn't technically feasible so I need to think of something else.

  • Redirect user to dir upon SFTP connection.

    - by Gabriel A. Zorrilla
    Hi guys. I have an FTP user which i log in into the server via SFTP and a key file. Right, lovely, works like a charm. Now, by default the user logs to /home/ftp which is not cool. I'd like to know if there is a way to redirect just before the connection to a dir such as /var/www/site.com/public/files/ Mmm? :)

  • Are there any advantages of GO Widgets over vanilla Android Widgets

    - by Supuhstar
    I use a suite of GO programs on my Android 4.1.2 device. Most relevant to this question, I've installed the GO Launcher EX and GO Weather, and they've recently given me the choice of one paid Go Weather Widget skin for free. Here, my conundrum lies: The skin I want comes in two versions: one for the GO Widget (can only be used on GO Launcher EX) and one for the vanilla Android widget. Are there any advantages for me choosing the GO Widget? I'm thinking things like increased performance because it'd be better integrated into the GO ecosystem, or more options, or something along these lines.

  • Firefox "auto-complete" is very slow

    - by netvope
    Firefox version: 3.6 My places.sqlite is rather big (114MB, after being optimized by SpeedyFox.) If I turn on auto-complete, it may take 1 or 2 seconds for Firefox to accept a newly typed URL. To reproduce the issue: Type a URL into the URL bar, press enter. Nothing happens, and Firefox consumes 100% CPU (actually 50% of 2 cores) for 1 to 2 seconds Then Firefox start the network connection and load the webpage. Since it consumes 100% CPU, I don't think the bottleneck is the disk. I have some experience with SQLite and I know a 100MB DB is very small. To achieve the delay Firefox must be doing some expensive processing or inefficient queries. The issue does not appear if: auto-complete is turned off, or the URL is frequently used, or a new profile with no history is used Does anyone have any idea how to solve the problem? Should I file this as a bug? I don't want to give up my 100MB history, but I don't want to give up auto-complete either :)

  • If Nvidia Shield can stream a game via WiFi (~150-300Mbps), where is the 1-10Gbps wired streaming?

    - by Enigma
    Facts: It is surprising and uncharacteristic that a wireless game streaming solution is the *first to hit the market when a 1000mbps+ Ethernet connection would accomplish the same feat with roughly 6x the available bandwidth. 150-300mbps WiFi is in no way superior to a 1000mbps+ LAN connection aside from well wireless mobility. Throughout time, (since the internet was created) wired services have **always come first yet in this particular case, the opposite seems to be true. We had wired internet first, wired audio streaming, and wired video streaming all before their wireless counterparts. Why? Largely because the wireless bandwidth was and is inferior. Even today despite being significantly better and capable of a lot more, it is still inferior to a wired connection. Situation: Chief among these is that NVIDIA’s Shield handheld game console will be getting a microconsole-like mode, dubbed “Shield Console Mode”, that will allow the handheld to be converted into a more traditional TV-connected console. In console mode Shield can be controlled with a Bluetooth controller, and in accordance with the higher resolution of TVs will accept 1080p game streaming from a suitably equipped PC, versus 720p in handheld mode. With that said 1080p streaming will require additional bandwidth, and while 720p can be done over WiFi NVIDIA will be requiring a hardline GigE connection for 1080p streaming (note that Shield doesn’t have Ethernet, so this is presumably being done over USB). Streaming aside, in console mode Shield will also support its traditional local gaming/application functionality. - http://www.anandtech.com/show/7435/nvidia-consolidates-game-streaming-tech-under-gamestream-brand-announces-shield-console-mode ^ This is not acceptable to me for a number of reasons not to mention the ridiculousness of having a little screen+controller unit sitting there while using a secondary controller and screen instead. That kind of redundant absurdity exemplifies how wrong of a solution that is. They need a second product for this solution without the screen or controller for it to make sense... at which point your just buying a little computer that does what most other larger computers do better. While this secondary project will provide a wired connection, it still shouldn't be necessary to purchase a Shield to have this benefit. Not only this but Intel's WiDi claims game streaming support as well - wirelessly. Where is the wired streaming? All that is required, by my understanding, is the ability to decode H.264 video compression and transmit control/feedback so by any logical comparison, one (Nvidia especially) should have no difficulty in creating an application for PC's (win32/64 environment) that does the exact same thing their android app does. I have 2 video cards capable of streaming (encoding) H.264 so by right they must be capable of decoding it I would think. I should be able to stream to my second desktop or my laptop both of which by hardware comparison are superior to the Shield. I haven't found anything stating plans to allow non-shield owners to do this. Can a third party create this software or does it hinge on some limitation that only Nvidia can overcome? Reiteration of questions: Is there a technical reason (non marketing) for why Nvidia opted to bottleneck the streaming service with a wireless connection limiting the resolution to 720p and introducing intermittent video choppiness when on a wired connection one could achieve, presumably, 1080p with significantly less or zero choppiness? Is there anything limiting developers from creating a PC/Desktop application emulating the same H.264 decoding functionality that circumvents the need to get an Nvidia Shield altogether? (It is not a matter of being too cheap to support Nvidia - I have many Nvidia cards that aren't being used. One should not have to purchase specialty hardware when = hardware already exists) Same questions go for Intel Widi also. I am just utterly perplexed that there are wireless live streaming solution and yet no wired. How on earth can wireless be the goto transmission medium? Is there another solution that takes advantage of H.264 video compression allowing live streaming over a wired connection? (*) - Perhaps this isn't the first but afaik it is the first complete package. (**) - I cant back that up with hard evidence/links but someone probably could. Edit: Maybe this will be the solution I am looking for but I still find it hard to believe that they would be the first and after wireless solutions already exist. In-home Streaming You can play all your Windows and Mac games on your SteamOS machine, too. Just turn on your existing computer and run Steam as you always have - then your SteamOS machine can stream those games over your home network straight to your TV! - http://store.steampowered.com/livingroom/SteamOS/

  • Windows 7 BSOD Crashes

    I recently upgraded to Windows 7 64 doing a clean install from Vista 64 and ever since I keep getting random blue screen crashes.

  • Why Is Web Sharing Broken on My Mac?

    - by Sam Murray-Sutton
    Background: I use my Mac for web development, running copies of web sites locally. I recently installed the Snow Leopard update, which to all intents and purposes seems to have gone fine, except... What's not working? Web-sharing; more specifically I can't turn it on via preferences. The preference pane just hangs when I try to. So Apache doesn't start on reboot. I can start Apache by hand, but I don't know enough to either setup apache to start with the computer, or to properly fix web sharing. Further details My Apache error log shows nothing on when the system boots up (as I would expect). This is the error message when I try to start web sharing from the sharing preference pane. 28/09/2009 10:58:05 System Preferences[834] setInetDServiceEnabled failed with 1 for org.apache.httpd Here's the messages given when I start apache from the command line.

Any help would be greatly appreciated. UPDATE I have added an answer of my own below - I was able to solve it thanks to being pointed in the right direction by the comments below, so thanks very much. But I'm still not totally clear as to what caused the problem or how my solution addressed it, so I'm leaving the question open for now.

  • Ubuntu Natty: 32-bit userland, 64-bit kernel?

  • Adding a new operator symbol to a custom language in Notepad++?

    - by Wolfpack'08
    I'd like to create a custom operator for a custom language I'm highlighting in Notepad++. Has anyone done this in the past? A special character that often comes up in my language is the yen symbol (?), and I would like to highlight the phrases immediately following and immediately preceding that symbol; unfortunately, I cannot figure a way to add a custom operator, of it is even possible. Also, if anyone has any additional tag recommendations, please edit.

  • Get Python to raise MemoryError instead of eating all my disk space

    - by asmeurer
    If I run a Python program with a memory leak, I would normally expect the program to eventually die with MemoryError. But instead, what happens is that all the virtual memory is used until my disk runs out of space. I am running Mac OS X 10.8 on a retina MacBook Pro. My computer generally has between 10GB to 20GB free. Mac OS X is smart enough to not die completely when the disk runs out of space (rather, it gives me a dialog letting me force quit my GUI programs). Is there a way to make Python just die when it runs out of real memory, or some reasonable amount of virtual memory? This is what happens on Linux, as far as I can tell. I guess Mac OS X is more generous than Linux with virtual memory (the fact that I have an SSD might be part of this; I don't know just how smart OS X is with this stuff). Maybe there's a way to tell the Mac OS X kernel to never use so much virtual memory that leaves less than, say, 5 GB free on the hard drive?

    - by Josip Medved
    I converted basic disk to dynamic on my laptop. However, now I cannot install Windows 7 on another partition. I just get message that installing them on dynamic disk is not supported. Is there a way to convert dynamic disk to basic without losing data on already existing partition?

  • Google Chrome - Issues with download dialogs using BinaryWrite

    - by Mila
    Hello, I have an empty ASP .NET page with the code behind to support downloading of PDF files. The page is called from a link-like web control that has NavigateUrl set to this page. In short, I am using the following for streaming: Response.Buffer = false; Response.ClearHeaders(); Response.ContentType = "application/x-pdf"; Response.AddHeader("Content-Disposition","attachment; filename="MyPDFFile.pdf"); byte[] binary = (dataReaderRemote[DataPDFFieldName]) as byte[]; //dataReaderRemote[DataPDFFieldName] has previously retrieved data if (binary != null) { MemoryStream memoryStream = new MemoryStream(binary); int sizeToWrite = CHUNKSIZE; //CHUNKSIZE=1024 for (int i = 0; i < binary.GetUpperBound(0) - 1; i = i + CHUNKSIZE) { if (!Response.IsClientConnected) return; if (i + CHUNKSIZE >= binary.Length) sizeToWrite = binary.Length - i; byte[] chunk = new byte[sizeToWrite]; memoryStream.Read(chunk, 0, sizeToWrite); Response.BinaryWrite(chunk); Response.Flush(); } } Response.Close(); IE as well as Firefox bring the download prompt window asking you whether you wish to open or save the file, while the user remains on the same page containing the link. However, Google Chrome opens a new blank tab and downloads the file automatically. Is there any way to prevent Chrome from opening the extra blank and therefore useless tab? I am using the Google Chrome version 5.0.375.55 (Official Build 47796) on Windows XP. Thanks in advance! Mila

  • What are possible ways to override User Access Control (UAC) while registering an ActiveX Control?

    - by Itz.Irshad
    In an ASP.NET 2.0 Application, an ActiveX control is used. When user first time access the appliction and he/she did not have that ActiveX registered. Application show a popup to install ActiveX. When user follow the process, ActiveX is registered and application loads the ActiveX to accomplish desired tasks. In Windows Vista, Win 7 and Win 8, User Access Control (UAC) is prompted to allow to install the ActiveX at very first time. This happens even if user is Administrator too. What are alternatives to override this UAC component while installing ActiveX ? Suggestions are appreciated.

  • How reliable are Compact Flash drives

    - by bakytn
    For example, USB drives have read/write limits. and they are considered as unreliable and not durable for daily use over many years. My question is, however, about Compact Flash drives. AFAIK they are built almost in the same way as USB flash drives. I was going to use one Compact Flash drive for daily usage and install a lightweight operating system to it (Linux). What kind of limitations do they have? Read/write operations? Just a time? something else? Thank you!

  • OSX: Selecting default application for all unknown and different file types (extensions)

    - by Leo
    I work in cluster computing and am using Mac OS X 10.6. I send off hundreds of computing jobs a day, and each one comes back with with a different extension. For example, svmGeneSelect.o12345 which is the std output of my svmGeneSelect job which is job number 12345. I don't control the extensions. All files are plain text. I want OSX to open any file extension that it hasn't seen before with my favorite text editor when I click on it. Or even better set up file association defaults for extension patterns ie textEdit for extensions matching *.o*. I do NOT want to create file associations for individual files since this extension will only ever exist once, and I do not want to go through the process of selecting the application to use for each file. Thanks for any help you can offer.

  • Free video capture programs for windows 7?

    - by chobo2
    I want to record my screen to make a tutorial. I tried to use camStudio but it goes all weird after a couple mins. Like I am recording then all of a sudden a popup from windows says that all the memory for colors is being used and it will stop using areo. Then a few mins later my screen starts going nuts and it starts flashing green. So I am not sure what to record and I can't afford to buy Camtasia.

  • Easy solution to monitoring & blocking connections to non-malicious services, IP's, and tracking companies

    - by binarybunny
    Our family lives in the middle of nowhere, so the only high-speed internet available is Verizon's 3G mobile broadband. We have the highest package available, yet continually go over the 10GB limit and get charged $10 every 1GB we go over. We run a business from home, so stopping when we hit the limit is not an option. I've found the majority of connections are to Google, Microsoft, Akamai, Facebook, and other web service companies (mainly google). I know these are harmless connections, but when it costs money for them to monitor our web activity it becomes a serious problem. Here's some things I've done, but I'm sure there's something else that could help before blocking a huge set of IP ranges: stopped using windows (on my machine) use MVPS host file on all computers use firefox on all computers (with don't track me option) ad block plugin on all browsers blocking google updates blocking windows updates block images in browsers (when possible) use comodo (paranoia-level style of blocking..) virus-free computers with ESET NOD32 bought router and installed dd-wrt in attempt to block connections more diligently (and throttle bandwidth if it comes to that) Anything I'm missing? I know Google analytics is on almost all websites, as well as FB like buttons but I would like to be able to stop these connections without blocking use of google services like gmail, etc. Any ideas?

  • What ssh command would I use to set up "backwards listening"

    - by Nathan
    Machine A is behind a firewall. I have physical access to it, but I want to log into it remotely, and I do not have access to the firewall settings. Machine B is remote, and not behind any firewall. (It's my linode) Machine C is the mobile device I'm going to attempt to ssh into A from. Is there an ssh command that I can run from machine A that connects to machine B and stays open, that will allow me to log into A from C, via B? From the manual I'd guess it would be to run the follwing on A ssh -R *:9999:localhost:22 me@B and then run this on C ssh me@B -p 9999 but the previous command reports "Connection refused."

  • Windows 8 & Hyper-V Can't Bridge Wifi Connection

    - by xinunix
    So I have an odd issue that I can't quite figure out... I am running Windows 8 Enterprise on a Dell 6420 laptop. I have a Broadcom 802.11n wireless adapter. I am connected to an home router (Netgear WNDR3700) that is connected to the internet. It is a very simple home network setup. I am trying to stand-up a few VMs in Hyper-V and want the VMs to be able to access the internet over my wireless connection. I have found numerous examples of how to set this up using both External and Internal Virtual Switches but have yet to be able to get it to work on my machine. I have narrowed the issue down to the fact that my host machine always loses internet connection when I bridge my wifi connection (both when it is bridged automatically by windows when I setup an external virtual switch bound to the wifi adapter or if I do it manually by creating an internal virtual switch, right click on it and my wifi network and select "Bridge Connections".) In both cases after the bridge is established, my host machine can no longer connect to the internet. I am not sure where to start with troubleshooting this problem. After the bridge is setup, an ipconfig shows all netowrk devices on the machine as "Media Disconnected". I do know that the wireless adapter is connected to the router b/c it shows the connection as active and full-strength. The only thing I can possibly think of is that this machine also has the Cisco VPN client installed on it which installs a Cisco Virtual Network Adapter. Is it possible that this Cisco Virtual Adapter is causing me issues when I try to bridge? I saw some people had a similar issue with a VirtualBox virtual adapter when trying to share via Hyper-V. Any thoughts or suggestions on how to troubleshoot?
