  • Randomize table guests in Excel

    - by Jo Voud
    I have a list of people: Column A: person A, person A guest, person B, person C, person C guest, ... Column B: 1, 1, 2, 3, 3, ... So in column A there is the person's name, column B gives a person a unique ID (the same id for their guest so we know that they are together). Now pretend we have a list of 100 people (also note that not all persons have guests) and we have to seat them. We have a list of tables (for example 10 * 4 person table and 10*6 person tables). We have to randomize that each person is assigned to a table and the guest is seated on the same table. What is the best way to do this? (it is also needed that I can generate this 4 times in a row without the same results, so when during the 4 courses of the diner the person are switching tables but not losing their guest).

  • copy WinXP Home recovery files to new SSD

    - by maGz
    My wife's Samsung netbook, which has Windows XP Home Edition OEM and a 5400 SATA 2 HDD, has finally crawled to (almost) a halt, and I've decided to install an OCZ SSD into it. The problem is that the machine came with no recovery media, but the recovery partition exists and I can boot into it. How can I go about creating a bootable DVD from that partition, and then boot off that to install on the SSD? NOTE: My aim after this is to upgrade to Windows 7 Home Premium, as the upgrade option is a lot cheaper than purchasing a retail or DSP equivalent.

  • USB HD Freezes Windows Explorer

    - by nfplee
    I recently purchased a "Seagate STBX1000200 1TB Expansion 2.5 inch External Hard Drive". It has been working without problems until recently. When i plug the device into a USB port the device is recognised as it appears in the device manager but when i go to Windows Explorer and try to open it (or right click on it) it hangs/freezes windows explorer. Please note i am using Windows 7 Professional. I have already tried various things without success after searching for people with similar problems. I did read that it could be a problem with how the computer assigns a drive letter. But whrn i go to disk management (when running as an administrator) it hangs and displays the following message: Connecting to virtual disk service I'd appreciate it if anyone could offer some advice. Thanks

  • What and all the areas of a Linux a PHP developer should know about? (Like just commands of it or something advanced)

    - by droidsites
    I've developed a website using PHP but I implemented it on Windows OS and hosted it on Windows server. I just searched the PHP job market to know the on-going technology requirement and to keep my knowledge up-to-date accordingly with the job market. I see more are asking for LAMP stack. I understand the sort of skills required for a developer in PHP and MySQL. But coming to the Linux and Apache what kind of the skills exactly companies expect from a developer? On what should I be focusing in case of Linux, Apache whilst developing my website using these LAMP stack? I am going to develop a new website and want it to be using LAMP. But I want to know what difference it makes? Why LAMP stack got more demand in the job market compared to WAMP ? Edit: Sorry I thought my question is creating confusion ... so I put my question in different words as What and all the areas of a Linux a PHP developer should know about? (Like just commands of it or something advanced) Note: I am Linux newbie

  • GitHub Not Accessible from Google Chrome

    - by KPthunder
    Whenever I try to go to GitHub through Google Chrome 11 I get the following error message: GitHub works perfectly fine in Firefox 4: This has been going on for a few weeks. This is a fairly new install of Windows (I don't even remember if I've successfully got on to GitHub on this installation with Chrome in the past). I don't even use GitHub for hosting my own code personally, but this has proven annoying in that I can't even access other people's projects through Chrome! Does anybody know what is going on here? An interesting side note: The Sight extension for Chrome doesn't work either! It worked on my old installation of Windows but not on this one. Is my Chrome installation just screwy? I've tried disabling certain other extensions but nothing seems to change.

  • phpMyAdmin logs out when selecting database

    - by deed02392
    I'm having an issue with pma whereby after logging in (as root or the database owner), and trying to switch to a certain database, I am automatically logged out. I cannot do any actions on the database and in the page that loads immediately before I'm logged out I note that I can't see any tables in the database. The database is accessible by the cli mysql program and all records are still present. To clarify: Literally login works fine, I can browse ALL databases except the one of my projects. Trying to use that database causes the phpMyAdmin session to end. Thanks!

  • Disable Control-L hotkey on YouTube

    - by Heptite
    I am used to using Ctrll to access my address bar. Unfortunately YouTube "helpfully" defines Ctrll as a hotkey to jump forward several seconds in the currently playing video, so I need a way to stop YouTube from adding that key binding. A Greasemonkey/Scriptish userscript that disables the binding after page load would be acceptable. To be clear, this is while I am on a YouTube video's page, not on a third-party site that has embedded a YouTube video, and the behavior occurs when the Flash player does not have focus. Note: I am aware that Altd does the same as Ctrll in Firefox, but I'm too used to Ctrll and I'd rather not be forced to switch. Edit: OS-specific solutions are less desirable since I use multiple OSes; in-browser solutions are preferred.

  • How large administrators team should be? [closed]

    - by Artyom
    I'm trying to find an answer about how many server administrators/technicians are required to run a server farm with 7/24 availability of let's 10, 100, 1000 Linux servers? Are there any studies for this? Edit I was not expected this question to be closed. There are lots of studies about for example software development where from "lines of code" you can approximate the software development cost (COCOMO), so I was searching for something similar in administration. Note, I'm 100% understand that it is not a straightforward or easy to answer question, but it is a real question...

  • How do I set up two existing disks with identical contents as a single mirrored volume in Windows 7 without losing data?

    - by Software Monkey
    I have two data disks that were, heretofore, in a mobo RAID configuration in Windows 7. They are now separate AHCI disks, visible in Computer Management. How to I go about making them a single mirrored volume in Windows? Note: The data is backed up up on two other separate disks, but it's a fair amount of work to do a restore (over 120'000 files, and I have to reset permissions). Note2: Currently the two disks are identical, and I can use the content of either one for this.

  • How to route traffic from VM (Parallels) over an Open VPN connection on the host (OS X)

    - by withakay
    Scenario: I have a Mac running Lion that is connected to an OpenVPN server I have a Windows XP VM (running on parallels, but I don't think this is important) I want to be able to route traffic from the XP VM via the host Mac's OpenVPN connection so that I can log on to a domain. The remote network is 172.16.0.0/23 (255.255.254.0) Open VPN is configured to supply address in the 10.100.101.0/24 range and sets up the routing to 172.16.0.0 using the gateway 10.100.101.1/32 My local network is 192.16.1.0/24 NOTE: I do not want to install OpenVPN into the XP virtual machine as I would have to use a passwordless key in order for OpenVPN to connect before logon. Anyone got any ideas?

  • crontab still sending emails even with > /dev/null

    - by user2344668
    I have a crontab (root) that runs a script and output is set to /dev/null but I always get the emails whenever it runs. I only want to receive error emails. # Rackspace driveclient update (12pm MST) 0 12 * * * /root/scripts/driveclient-update > /dev/null The only way I can get it to turn off is to use /dev/null 2&1 but then I won't get error emails. This is happening on three different CentOS servers, two are 6.3 and one is 6.4. NOTE: I have read over and over that /dev/null is supposed to send stdout there and prevent the email if there is nothing but stdout from the script, so at works for at least some people; I cannot figure out why it is not working on these servers. Here's an example of where /dev/null is supposed to work: http://www.alphadevx.com/a/384-Suppressing-Cron-Job-Email-Notifications

  • Should I always encapsulate an internal data structure entirely?

    - by Prog
    Please consider this class: class ClassA{ private Thing[] things; // stores data // stuff omitted public Thing[] getThings(){ return things; } } This class exposes the array it uses to store data, to any client code interested. I did this in an app I'm working on. I had a ChordProgression class that stores a sequence of Chords (and does some other things). It had a Chord[] getChords() method that returned the array of chords. When the data structure had to change (from an array to an ArrayList), all client code broke. This made me think - maybe the following approach is better: class ClassA{ private Thing[] things; // stores data // stuff omitted public Thing[] getThing(int index){ return things[index]; } public int getDataSize(){ return things.length; } public void setThing(int index, Thing thing){ things[index] = thing; } } Instead of exposing the data structure itself, all of the operations offered by the data structure are now offered directly by the class enclosing it, using public methods that delegate to the data structure. When the data structure changes, only these methods have to change - but after they do, all client code still works. Note that collections more complex than arrays might require the enclosing class to implement even more than three methods just to access the internal data structure. Is this approach common? What do you think of this? What downsides does it have other? Is it reasonable to have the enclosing class implement at least three public methods just to delegate to the inner data structure?

  • Computer temporarily freezes and then resumes

    - by trizicus
    This happens on ALL operating systems (7, Ubuntu, etc.). What happens is everything for 1-3 seconds becomes unresponsive, I then hear what sounds like my other internal hard drive 'spinning up', and then viola everything is responsive again. Note: Already ran SMART tests, no issues at all. I think issue is that the HDD spins down and when need it gets 'turned-on' (OS settings turn off HDD's after 20 mins of inactivity) and because my pagefile is on the other HDD it causes OS to temporarily freeze. Need more tips, and insight. Thanks More info: Running Quad CPU, 4GB RAM, Intel SSD, GT 240.

  • what should I read in Windows [closed]

    - by Umesha MS
    I think I am asking generic question. Being a developer in windows what should I read to improve my skills? Do I need to read concepts on need basis or do I need to read concepts well in advance? If I want to read the concepts in advance then what topics do I need to read. (Note : I am a Windows developer. I use c++ programming language, Win32/MFC frame work and I use Visual studio IDE.) Updated: To be more specific when a fresher comes to my team I will ask him to read the following things and I tell him that these are very important. 1)C++ : 1 The C++ Programming Language by Bjarne Stroustrup's 2 Thinking in C++ 2nd Edition by Bruce Eckel 2)Win32/MFC : 1 Programming Applications for Microsoft Windows by Jeffrey Richter 2 windows programming by charles petzold 3 Programming Windows with MFC –by Jeff Prosise For 2 years and above developer I ask them to read 1)Above concepts (C++ and Win32/MFC)are mandate 2)Design Pattern : 1)Gang Of Four. 2)Head first patter. 3)Design princples. But for above 6 years’ experience developer what are the concepts are important.

  • How do I automatically start Clamz with AMZ files for Amazon MP3 downloads?

    - by Takkat
    Chromium can open downloaded files with the default application (e.g. PDF in Evince). In my setup a downloaded .AMZ (for Amazon MP3) always opened with Gedit. However I would like to have all downloaded .amz files to autromatically open with Clamz, a command line tool for downloading that works like a charm. As in Nautilus my .amz files were associated to open with Gedit too I thought it was a good idea to add a clamz.desktop file in ~/.local/share/applications (according to this answer) [Desktop Entry] Encoding=UTF-8 Name=Clamz Comment=Open AMZ files for Amazon MP3 download Exec=/usr/bin/clamz %u Terminal=True Type=Application Icon= Categories=Application; StartupNotify=true MimeType=audio/x-amzxml; NoDisplay=true This lets me choose Clamz as default application in Nautilus. But when opening an .amz file in Nautilus it still does not open with Clamz as expected but is treated as an executable text file instead (note that the executable bit is not set!). Is there any other way to make Chromium or Nautilus always open an .amz file with Clamz? Did I miss to change setting in another place?

  • OpenGL : sluggish performance in extracting texture from GPU

    - by Cyan
    I'm currently working on an algorithm which creates a texture within a render buffer. The operations are pretty complex, but for the GPU this is a simple task, done very quickly. The problem is that, after creating the texture, i would like to save it. This requires to extract it from GPU memory. For this operation, i'm using glGetTexImage(). It works, but the performance is sluggish. No, i mean even slower than that. For example, an 8MB texture (uncompressed) requires 3 seconds (yes, seconds) to be extracted. That's mind puzzling. I'm almost wondering if my graphic card is connected by a serial link... Well, anyway, i've looked around, and found some people complaining about the same, but no working solution so far. The most promising advise was to "extract data in the native format of the GPU". Which i've tried and tried, but failed so far. Edit : by moving the call to glGetTexImage() in a different place, the speed has been a bit improved for the most dramatic samples : looking again at the 8MB texture, it knows requires 500ms, instead of 3sec. It's better, but still much too slow. Smaller texture sizes were not affected by the change (typical timing remained into the 60-80ms range). Using glFinish() didn't help either. Note that, if i call glFinish() (without glGetTexImage), i'm getting a fixed 16ms result, whatever the texture size or complexity. It really looks like the timing for a frame at 60fps. The timing is measured for the full rendering + saving sequence. The call to glGetTexImage() alone does not really matter. That being said, it is this call which changes the performance. And yes, of course, as stated at the beginning, the texture is "created into the GPU", hence the need to save it.

  • WebsitePanel 2 totally NOT working on Windows Server 2012 on Azure

    - by Carmine Giangregorio
    I’m having many troubles installing WebSitePanel on an Azure Virtual Machine, with Windows Server 2012. I followed the steps in http://www.websitepanel.net/documentation/deployment-guide/server-configuration/preparing-windows-server-2008-r2-for-websitepanel-installation/ and installed everything I needed. Then, I installed the WebSitePanel Standalone Server package with the installer. I opened the endpoint for the port 9002 on Windows Azure; so I pointed my browser to myhostname.cloudapp.net (note: in Azure you don’t have a static IP address, instead you have an hostname like [hostname].cloudapp.net). So, loading myhostname.cloudapp.net:9002 fails, and any browser shows something like “Unable to load page”. Notice: if I try to load the WebSitePanel Portal directly on the server, I get an error HTTP 400 Bad Request. How come? IIS works perfectly on the server, in fact the default website runs without problems on port 80.

  • Two Hidden NetBeans Keyboard Shortcuts for Opening & Toggling between Views

    - by Geertjan
    The following are two really basic shortcuts for working with NetBeans editor windows that will be added to the Keyboard Shortcuts card for NetBeans IDE 7.2: Ctrl-Alt-PgUp/PgDown: Shortcuts for switching between editor types (e.g. Source, Design, History buttons). Switching between the editor types is a frequent operation sometimes, e.g., when using GUI builder, and while it can be done easily via mouse, or from View | Editors menu, it is very handy to know the shortcuts as well. Ctrl-PgUp/PgDown: Similarly, these are shortcuts for switching to next/previous opened document (tab). Note this is not like Ctrl-Tab that cycles in the last used order, but going through the tabs as they appear in the editor. Both shortcuts should fit into the "Opening and Toggling between Views" section. These are important to mention on the card because they are not visible anywhere else in the UI (as there are no menu items like "Go to next/previous editor type" or "Go to next/previous document"). Reported by Tomas Pavek from the NetBeans Team, here: http://netbeans.org/bugzilla/show_bug.cgi?id=213815

  • Autosaving on emacs or xemacs files (preferably on loss of focus)

    - by Spencer
    Ideally I want to replicate with emacs functionality from TextMate, whereby on loss of focus i.e. I click away from the buffer, my file saves. If this isn't possible, I want to customize emacs so that it will autosave the file for every character I write. When I say this I don't mean I want to autosave to the ~ backup files. I want to save the file I am currently working on. I am working on a Fedora VM. Note I am not looking for a backup or autosave. I want the file I am actually in to save, so that if I loaded the html file I am editing in a web browser it would reflect my new changes without me having to explicitly change it.
