  • Recomposing data structure in Excel

    - by Velletti
    I've got a sheet of 35k rows of the following kind of data that I want to reshape into table below. So, I want to reshape this data in a way to get all the people within a specific GroupID in separate columns. I suppose that I should add a counter for each row within specific group id? Also, I suppose these kind of issues are a lot more comfortable to be done in databases? Since I often have this kind of data, I need be much quicker about solving it, then I am now.

  • C++ - my loop keeps on adding up to 0

    - by user1756913
    so far here's my code #include <iostream> using namespace std; int main () { int num1 = 0; int num2 = 0; int sum = 0; for(num2 = num1; num1 <= num2; num1 +=2) sum += num1; num1 = num1 / 2 == 0? num1 : num1 + 1; num2 = num2 / 2 == 0? num2 : num2 - 1; cout << "Enter the First Number:" << endl; cin >> num1; cout << "Enter the Second Number:" << endl; cin >> num2; cout << "Total Sum: " << sum << endl; } //end for but the sum keeps on adding up to 0 :/ here's the problem. Create a program that displays the sum of the even numbers between and including two numbers entered by the user. In other words, if the user enters an even number, that number should be included in the sum. For example, if the user enters the integers 2 and 7, the sum is 12 (2 + 4 + 6). If the user enters the integers 2 and 8, the sum is 20 (2 + 4 + 6 + 8 ). Display an error message if the first integer entered by the user is greater than the second integer.

  • With Ubuntu 12.04 unlike 11.04 Wine installed application start menu links are missing

    - by Ron Whites
    With Ubuntu 12.04 and wine 1.4 unlike ubuntu 11.04 with wine 1.2.2 installed application start menu links are missing. For instance with Ubuntu 11.04 including Wine I can install one of our Windows applications and then can go to Applications Wine Programs Semantic Designs TestCoverage Documentation to bring up the documentation for how to run our tool. Unfortunately with Ubuntu 12.04 the Applications menu is gone and going to Dash I do see "Recent Apps and more apps" but my installed Wine application and related documentation link is shown present, even though the wine uninstaller shows in present. I found this online suggestion and tried using the gnome "main menu"... Windows key to launch the Dash. Enter "Main Menu" in the search field and open the old Edit Main Menu app. Select the Category (aka Unity Dash Filter) you want the item in. Name the Dash/Launcher Item Add the Command to launch said app With "mainmenu" then get down to the TestCoverage Documentation and I could see a command link in properties of .. env WINEPREFIX="/home/sdtest/.wine" wine C:\windows\command\start.exe /Unix /home/sdtest/.wine/dosdevices/c:/users/sdtest/Start\ Menu/Programs/Semantic\ Designs/Test\ Coverage/Java\ 1.7\ Documentation.lnk BUT I could not execute this link to view the installed documentation. So I copied the link properties into a file, set it as executable, and ran it as a bash script and the documentation came up! So why can't I use this link under main menu?

  • Encrypted directory makes file operations for whole disk very slow

    - by user1566277
    I am running an arm GNU/Linux and I have a SD-Card with three partitions on it. On one of the Partition I create an encfs file and then mount it on a directory which is in another partition to make that directory encrypted. Works fine. But now the writing speed on all the partitions are reduced drastically. I can understand that it should be slow for encrypted directory but why the its reducing write speed for all the partitions. E.g., if do not mount the encrypted directory 20MB is transferred in 2 Sec. roughly but with the encrypted directory mounted its like 20 Seconds for same file. I am using LUKS and all the partitons are ext3 except for the directory where /dev/mapper/encfs is mounted as type ext2. Any hints?

  • Can no longer duplicate display to external monitor on Windows 7

    - by rbeier
    We have a large TV at work - I connect my laptop to it to share my screen during meetings. Until today, my laptop display has been duplicating to the TV automatically when I connect the TV cable to the laptop. The display resolution would decrease automatically to be compatible with the TV. Today, however, it's stopped working. When I connect the cable to the TV, the display extends rather than duplicating. Using the Win+P key combination (or Fn+F7 on my Lenovo laptop), I can choose to duplicate the display - but when I do this, it ends up only displaying on the laptop. I can get it to display on the TV by hitting Win+P and choosing "projector only", but then I can't see what I'm doing on the laptop screen. I have a Lenovo W520 laptop running Windows 7, connected to the TV using a DisplayPort-to-HDMI converter cable. The TV's native resolution is 1280x720; the laptop's native resolution is 1600x900. I've tried booting with the TV cable already connected; I've tried manually lowering the display resolution on the laptop to 1280x720 before duplicating the display. Neither works. Does anyone have any other suggestions?

  • USB Drive that simultaneously connects to more than one computer

    - by user2499
    Background: I have a portable USB drive that I use to make sure I have access to common files whenever at home, work, travel etc for cases when I may not have Internet/Network access of any kind. There are some cases when I have to work simultaneously on a laptop and a desktop computer, and for those cases I usually have to unplug this USB hard drive and move it between the two. Question: dual-computer USB drive? Is there a USB-based solution that would enable me to use this portable drive between two computers simultaneously? If there is not a USB-based solution, does anyone have alternative suggestions, consistent with the underlying rationale? Rationale: Sometimes I have to work on a desktop computer with locked-down networking capabilities (such as at the local photocopy shop) and it can be difficult to get a network configuration that allows dual-computer access without breaking things, or accidentally making my USB drive visible to the entire network. Basically what I need is a very simply LAN that is guaranteed to work regardless of the rules or constraints set by the network administrator for wherever I happen to be at the time.

  • What is the `/etc/hostname` used/required for?

    - by static
    I found in the /etc/hostname my IP-address, than I deleted it and each time I use sudo - I get a message and a system email sudo: unable to resolve host (none) or if in the /etc/hostname is saved myhostname than sudo: unable to resolve host (myhostname). I know it is used to set the system's hostname via /etc/init.d/hostname.sh while booting process, but what is this setting required for (programs, services, daemons ...)? What if i set to localhost (so it doesn't happen any sudo: unable to resolve host (none) anymore, but is it still ok?)? UPD1: I found some information here: http://jblevins.org/log/hostname, but it is all about how to use it and not about - why it is required.

  • Print from MAC OS 10.5.8 to HPC3180 on Windows 7, How?

    - by Tom Groszko
    Can anyone point to a document that describes how to print from a Max OS 10.5.8 to an HP Photosmart C3180 series print connected to Windows 7. I can’t get anything but nonsense to print. I was able to do this with Windows XP, could not do it with Vista and am now hopping to get it done with System 7. HP has been no help at all. Apparently nobody who works for them knows anything about both computers.

  • Thunderbird, Windows 7: How can I get a unique list of people who have sent me an email

    - by Parris
    Is there some command within Thunderbird or command line to will allow me to pipe a list of all email addresses I've received emails from to a file? I would like to do this for a specific email account and folder within Thunderbird as well, and not just all of my accounts. I have maybe 100 unique people who have sent me an email for some contest and it would be optimal not to have to type all of this stuff up by hand. Thanks!!!

  • Windows 7 startup MUCH slower after reinstall (on an SSD)

    - by user326639
    I installed Windows 7 Prof 64 bits OEM (Spanish) on my new machine. As I wanted my Windows to be in English, the web shop where I bought the DVD recomended me to download an ISO file with the same Windows version (but in English), burn it on a DVD and install it. And that I should be able to use my registration code. Location ISO: http://msft-dnl.digitalrivercontent.net/msvista/pub/X15-65805/X15-65805.iso I've done this and everything works (I have not activated my Windows yet but I expect no problem there). Just one thing: its startup is MUCH slower now! Have a look at my PC specs (bottom). On my first install (Spanish), it was like: - motherboard splash screen -- shows for a second or two - list of found drives -- a few seconds - the text "Windows starting" -- about a second before the dots appear - four collored dots form the Windows logo -- a few seconds after the logo is fully formed it moves on to the login screen. On my second install (English): - motherboard splash screen -- shows for 15 seconds - list of found drives -- a few seconds - the text "Windows starting" -- shows for 40 seconds before the dots appear - four collored dots form the Windows logo -- now it moves on to the login screen about equally fast as before. Ones it's up and running it seems to be as responsive as before, although it's possible that I'm not noticing the difference. I did the first install on the virgin SSD drive straight from the box. The second time I let the Windows installation program format the drive first to get rid of the old installation. I noticed that there were two partitions on my SSD: partition 1, 100 Mb, "reserved for the system" and partition 2, 111.7 Gb. I only formated the big partition, and I left the system partition untouched. Between the two installs, I didn't open the computer so everything is connected to the same port. I did not change anything in BIOS. Has Windows not recognized my SSD as an SSD but as a normal HDD. I suspect that Windows has not done the neccesary automatic configuration settings that it should do for SSD's (but that's just a hunch). How do I get my SSD back into its virgin state, as if it came right from the box, so I can go for a 3rd attempt to install windows. Should I use DISKPART? Other ideas are welcome. Specifications: mobo: Gigabyte GA-Z68X-UD3H-B3 CPU: i7-2600K SSD: OCZ Agility3 2,5" HDD: Samsung Spinpoint F4 mem: Kingston HyperX DIMM 8 Gb DDR3-1600

  • Host file in browser?

    - by acidzombie24
    Instead of changing my host file i'd like firefox to think my domain is on my own server while my other browser to use the real ip address. I use to edit my host files but that forces both browsers to change the ip address. I found change hostbut it doesnt appear to use the alternative host file. I also saw a comment asking when it will work on firefox 6+ I tried Host Admin and it fails. It works but the alternative IP address must be in your host file already (which i dont want) and it lets you deselect a domain so the host file is ignored. Not what i want.

  • My CPU hits 100°C... Help me!

    - by JamesT
    The safe limit for processors is typically 50°C or so, but I have found that my CPU likes to do up to 100°C. I have got these readings from SpeedFan 4.42. I have a Intel Quad Core unclocked. I am using the standard intel fan with heatsink that came with the prossesor My case is a Cooler Master and I have two fans installed on the case. I took the side off to see if that helped. It lowered the temp be 3C. I don't really want to blow the processor and I don't know how to cool it down.

  • zune - how do i make the PC zune download a movie, not stream it?

    - by bharal
    As the title suggests - I have bought a tv show series season on PC Zune. My gf watched the show, and now i'd like to be able to watch the show too. The catch - i'm going to go overseas on a trip soon, and i'd like to be able to watch the show from outside the US. Given that Zune won't let me stream things overseas (past experience, anyway), I would like to download the show to my computer and watch it that way. The problem is that although the full season has been "watched" it appears it was only streamed, not downloaded. Or rather, that one episode was downloaded, and the rest streamed. I bought a season pass (so all the episodes at once) and the show was bought, not rented. How do i make Zune download, not stream, a show?

  • Run script on login with ssh

    - by user912447
    I have a feeling this is quite easy to do but every solution found on google has to do with adding a script to be run whenever someone logs into the machine. What I am looking for is a way to run a script when only I log into the machine. I ssh into a shared computer and need to have it load a couple modules for me and I imagined the easiest way to do this would to just run a script on login. Is there a simple way?

  • How can I get Dreamscene wallpapers to change randomly in Win7?

    - by andygrunt
    Having only recently moved over from Windows XP to Windows 7, I’m a big fan of the ‘Dreamscene’ animated wallpaper. I’m also a big fan of the Win 7 ability to select a group of still wallpaper bitmaps and set it to randomly change wallpapers every ‘X’ minutes/hours. What I want is the ability to do the same with the dreamscene animated wallpapers, i.e. select a group and they randomly change every ‘X’ minutes. Beyond that, I’d also like to be able to select a group of stills and animated wallpapers and randomly change between them.

  • System requirements for running windows 8 (basic office use) in virtualbox (ubuntu as host os)

    - by Tor Thommesen
    I want to run windows 8 as a guest os with virtualbox on some thinkpad (haven't bought one yet) running Ubuntu 12.04. Apart from virtualizing windows 8 (mostly just for use with the office suite app) my needs are very modest, I don't need much more than emacs and a browser. What I'd like to know is what kind of specs will be necessary to run windows 8 well as a vm, using the office apps. It would be a shame to waste money on overpowered hardware. Are there any official guidelines from oracle or windows on this? Would this lenovo x220, for example, be sufficiently strong? The specs below were taken from this review. Intel Core i5-2520M dual-core processor (2.5GHz, 3MB cache, 3.2GHz Turbo frequency) Windows 7 Professional (64-bit) 12.5-inch Premium HD (1366 x 768) LED Backlit Display (IPS) Intel Integrated HD Graphics 4GB DDR3 (1333MHz) 320GB Hitachi Travelstar hard drive (Z7K320) Intel Centrino Advanced-N 6205 (Taylor Peak) 2x2 AGN wireless card Intel 82579LM Gigabit Ethernet 720p High Definition webcam Fingerprint reader 6-cell battery (63Wh) and optional slice battery (65Wh) Dimensions: 12 (L) x 8.2 (W) x 0.5-1.5 (H) inches with 6-cell battery Weight: 3.5 pounds with 6-cell battery 4.875 pounds with 6-cell battery and optional external battery slice Price as configured: $1,299.00 (starting at $979.00)

  • Is there a fix for Windows 8 Release Preview freezing intermittently on Macbook Air

    - by RyanCEI
    I've successfully installed Windows 8 x64 Release Preview on a 2010 Macbook Air (4GB/256GB). I was also able to install the Apple Boot Camp tools without incident, but the computer will intermittently freeze up completely (need a forced shutdown) for no apparent reason. As such, there is no logging information to help me troubleshoot this any further. I have no other software installed at this point; only the latest updates from Microsoft. Any ideas?
