  • What operating systems are used in airplanes, and what programming languages are they developed in?

    - by adhg
    I was wondering if anyone knows what is the operating system used in commercial airplanes (say Boeing or Airbus). Also, what is the (preferred) real-time programing language? I heard that Ada is used in Boeing, so my question is - why Ada? what are the criteria the Boeing-guys had to choose this language? (I guess Java wouldn't be a great choice if the exactly in lift off the garbage collector wakes up).

  • Ruby installed on Ubuntu 10.10 slow on one machine but not other

    - by Aaron Jensen
    I have a machine that was provisioned several months ago. RVM was used to install ruby 1.9.3-p125 as well as 1.9.3-p125-perf. When I compared raw ruby performance to another identical machine the older machine smoked them. For example: ================================================================================ With in-block needle calculation ================================================================================ Rehearsal ---------------------------------------------- detect 3.790000 0.000000 3.790000 ( 3.800895) each 2.410000 0.000000 2.410000 ( 2.420860) any 3.960000 0.000000 3.960000 ( 3.972099) include 1.440000 0.000000 1.440000 ( 1.442862) ------------------------------------ total: 11.600000sec vs ================================================================================ With in-block needle calculation ================================================================================ Rehearsal ---------------------------------------------- detect 10.740000 0.000000 10.740000 ( 10.769366) each 6.080000 0.010000 6.090000 ( 6.106323) any 10.600000 0.000000 10.600000 ( 10.641606) include 4.160000 0.000000 4.160000 ( 4.171530) ------------------------------------ total: 31.590000sec I attempted to reinstall 1.9.3-p125 with rvm on the fast machine and that ruby is now slow. It's as if something changed in RVM, or I installed some package that made compiled versions of ruby perform significantly worse. I know this is a tough question to answer, but what things should I look into in order to track down why the performance has suffered so much? edit I just attempted to install with ruby-build and the version installed was fast. Something rvm is doing to build it in my environment is slow.

  • How to make a PHP function triggered automatically at a user defined time

    - by mithilatw
    I am developing an internal system for a company with PHP using Zend framework. I need one of its functions to execute on a time specified by user. My research on this matter found me several ways of doing this using CPanel Cron jobs and setting up scheduled tasks on the server. But in this scenario, I don't have a CPanel and I already use scheduled tasks. But my challenge is to provide an interface for the user to specify the time to trigger the function.

  • How to create a temporary staging server on my home machine [closed]

    - by Homunculus Reticulli
    Possible Duplicate: What things required to host a website at home I want to create a temporary staging server which can be accessed (i.e. via browser) by other people that I want to show the website to (a business partner who is half way accross the world). IIRC, my ISP issues dynamic addresses so I may need to register with a (DNS server?) - not sure about this.

    - by Tom D
    I want to log every time I run a certain type of command in the terminal. For example, every time I run: sudo apt-get install [something] I want to add [something] to a log file in my home directory that will look like the following: [timestamp] [something] 2012-10-02 mysql-server 2012-10-03 ruby1.9.1 2012-10-06 gedit-plugins 2012-10-07 gnome-panel synaptic What's the easiest way to make this happen automatically?

  • Getting wireless to work on Ubuntu 11.10 (on a mac machine)

    - by yayu
    I have a 2008 white 13.3 inch macbook that now solely runs ubuntu. However, I cannot get wifi or cable to work on it. Regarding the cable, it atleast tries to connect but eventually disconnects from the wired network. Here is the output for lspci (pastebin) I tried installing b43-fwcutter and firmware-b43 but get errors. (I loaded them from a thumb drive and tried sudo dpkg -i). I cannot understand these instructions from the documentation, as I cannot locate the pool directory. b43-fwcutter is located on the Ubuntu install media under ../pool/main/b/b43-fwcutter/ and patch is located under ../pool/main/p/patch/ or both in the official repositories online. Note: In some versions (10.04 and 11.04 at least) there is not a /pool/main/p/patch/ If this file is missing then you don't need it. In this case you only need to install /pool/main/b/b43-fwcutter by following the instructions below.

  • How can I access user files on a disk moved from a Windows 7 machine to an XP machine?

    - by Fantius
    I moved the hard drive from one machine (Win 7) to another (XP) and now certain folders tell me "Access denied". I am logged in as an administrator. I had a different account on the other machine. Neither account authenticated to anything besides the local machine. The old machine is apparently dead, so I can't do anything in there like change permissions, etc. How can I access these files? Edit: After changing the ownerships of all the files and folders on the drive, I am getting a different error. And it is troubling me deeply. "xxx refers to a location that is unavailable. It could be on a hard drive on this computer, or on a network. Check to make sure that the disk is properly inserted, or that you are connected to the Internet or your network, and then try again. If it still cannot be located, the information might have been moved to a different location." No change after rebooting. Any ideas? Surely the files are still there, right?

  • Installing multiple ubuntu partitions on same machine without corrupting GRUB

    - by LGB
    I had only ubuntu installed on my pc, but I felt like adding another ubuntu (same version) partition so I could have one just for work/study and another one just for personal generic use. I installed it and it worked out okay, but I found I needed more space on the new created Ubuntu partition, so I booted up from the Live CD, and used GParted to move/shrink/grow the partitions as the Ubuntu's tutorials suggested it was pretty straightforward. But in doing all this I messed up with Grub, so when I start my system it shows: error: unknow filesystem grub rescue What would be the easiest way to recover it so I could have both partitions working? Btw, it wouldn't be a problem for me to lose the partitions if it's the shortest/easiest way. Thanks in advance.

  • Menu to let me choose OS to run in a dual boot machine

    - by user1145905
    I recently re-imaged my Dell PC to dual-install Windows 7 and Ubuntu 12.04.1 LTS. The dual-boot was a success, since I was able to start whichever OS I wanted. Now, I installed some software (the OpenJDK package) on the Ubuntu side of the PC. Upon restarting Ubuntu, I unfortunately lost the ability to choose the OS that I wanted to run (i.e., Ubuntu). Ordinarily, I'd expect to: 1. Hit the power button 2. A menu (Grub?) shows up listing all OSs installed in the PC (namely, Win7 and Ubuntu) 3. Choose which OS I want and hit enter. bingo. The problem is that I don't see that menu (step 2 above). Instead, windows automatically starts, even when I hit F12 to see the boot options, none of which I understand. Your help would be great! Thanks! - Kiptoo

    - by The Geek
    Today at 11:11 and 11 seconds, the date and time will be a perfect same-number palindrome—that is, it will read the same backwards and forwards, using the same number. It will be 11:11:11 on 11/11/11, and that won’t happen again for another 100 years. Naturally, it’ll happen again at 11 PM, for those that don’t observe military time.

  • How to access Virtual machine using powershell script

    - by Sheetal
    I want to access the virtual machine using powershell script. For that I used below script, Enter-PSSession -computername sheetal-VDD -credential compose04.com\abc.xyz1 where, sheetal-VDD is hostname of virtual machine compose04.com is the domain name of virtual machine and abc.xyz1 is the username of virtual machine After entering above command , it asks for password. When the password is entered I get below error, Enter-PSSession : Connecting to remote server failed with the following error message : WinRM cannot process the reques t. The following error occured while using Kerberos authentication: There are currently no logon servers available to s ervice the logon request. Possible causes are: -The user name or password specified are invalid. -Kerberos is used when no authentication method and no user name are specified. -Kerberos accepts domain user names, but not local user names. -The Service Principal Name (SPN) for the remote computer name and port does not exist. -The client and remote computers are in different domains and there is no trust between the two domains. After checking for the above issues, try the following: -Check the Event Viewer for events related to authentication. -Change the authentication method; add the destination computer to the WinRM TrustedHosts configuration setting or us e HTTPS transport. Note that computers in the TrustedHosts list might not be authenticated. -For more information about WinRM configuration, run the following command: winrm help config. For more information, see the about_Remote_Troubleshooting Help topic. At line:1 char:16 + Enter-PSSession <<<< -computername sheetal-VDD -credential compose04.com\Sheetal.Varpe + CategoryInfo : InvalidArgument: (sheetal-VDD:String) [Enter-PSSession], PSRemotingTransportException + FullyQualifiedErrorId : CreateRemoteRunspaceFailed Can someone help me out in this?

  • Efficient algorithm for Virtual Machine(VM) Consolidation in Cloud

    - by devansh dalal
    PROBLEM: We have N physical machines(PMs) each with ram Ri, cpu Ci and a set of currently scheduled VMs each with ram requirement ri and ci respectively Moving(Migrating) any VM from one PM to other has a cost associated which depends on its ram ri. A PM with no VMs is shut down to save power. Our target is to minimize the weighted sum of (N,migration cost) by migrating some VMs i.e. minimize the number of working PMs as well as not to degrade the service level due to excessive migrations. My Approach: Brute Force approach is choosing the minimum loaded PM and try to fit its VMs to other PMs by First Fit Decreasing algorithm or we can select the victim PMs and target PMs based on their loading level and shut down victims if possible by moving their VMs to targets. I tried this Greedy approach on the Data of Baadal(IIT-D cloud) but It isn't giving promising results. I have also tried to study the Ant colony optimization for dynamic VM consolidating but was unable to understand very much. I used the links. http://dumas.ccsd.cnrs.fr/docs/00/72/52/15/PDF/Esnault.pdf http://hal.archives-ouvertes.fr/docs/00/72/38/56/PDF/RR-8032.pdf Would anyone please clarify the solution or suggest any new approach/resources for better performance. I am basically searching for the algorithms not the physical optimizations and I also know that many commercial organizations have provided these solution but I just wanted to know more the underlying algorithms. Thanks in advance.

  • A tale of UAC on a Windows 7 Development Machine

    - by TATWORTH
    This week I faced an interesting problem on a Windows 7 Development PC. I have run MakeLog (http://commondata.codeplex.com/releases/view/13206) sucessfully on my PC but my colleague could not run it sucessfully. Both of us are local administrators, so what I could do on my PC, he should have been able to do. The cure was to turn UAC completely off and re-boot. Once re-booted, the installation ran without incident. While I would never suggest turning off UAC normally, on development PCs, it is a liability as it stops many normal operations and occasionaly without giving a prompt.

  • Remove ubuntu when it's the only OS on the machine

    - by Frances
    I've been trying for hours to remove ubuntu 12 which is the only OS on my laptop. I don't have a Windows installation there. I've followed various bits of help, including trying to get boot-repair to work (I just get error messages when I try to run the recommended commands). Please can someone tell me how to get rid of ubuntu? It won't recognise my .iso copy of Windows - tries to read the DVD and then just boots ubuntu anyway. The DVD is fine - I can use it on other computers and it's perfectly OK. Frances

  • How detailed should your report/invoice be for hourly work? [on hold]

    - by Marcus Cavanaugh
    When working on development projects (like an iPhone app for a client), how detailed should your reports be when providing an invoice? In other words, how specific should you be regarding the particular development tasks you were working on at a given time? Just as helpful would be a short example of what one of your invoices looks like, with sample times and tasks that you would typically include.

  • Do I need to use any other attributes other than CssClassProperty to enabled design-time support?

    - by keith
    Hi, I'm trying to provide the same design-time support that the CssClass provides on some custom properties of a server control. The documentation suggests that decorating the property with the CssClassProperty is all that's required. [CssClassProperty] public string SomeOtherCssClass{get;set;} This has no effect, in vs2008 or vs2010. I've looked at the WebControl class using reflector and implemented all the attributes, and every combination thereof, to my property and still no class dropdown. Some blog posts suggest that the use of the Editor attribute but a) there's not mention of it in the documentation and b) none of editors which are remotely related to css classes have any effect either. Am I missing something to enable this feature? Thanks in advance, Keith.
