  • How can I set a Windows user environment variable that takes effect for the current session?

    - by Graham Powell
    I am trying to set a Windows user environment variable and then launch an application via either batch file or a script. However, the environment variable is not set to the appropriate value until after the user logs off and logs back on. (I think a more accurate description would be that the new value is not available to the app until after the next logon.) Is there any way to set a variable in the user's environment so that it's immediately available? I'm doing this because this program's functionality can be controlled by environment variables, and users will need different functionality at different times. Because of license constraints I need to set this dynamically, if possible. Thanks, Graham

  • I want to plot ocean current with a GPS in a bottle.

    - by Fantomas
    Thinking of using a wine bottle with a cork that barely sticks out. Anyhow, I want to put in a GPS, a battery and a transmitter and to be able to collect position about every minute or so. Off-the-shelf components are preferred. What are my options as far as hardware and software choices? Thank you in advance!

  • Is there a historical computer peripherals or accessories museum or even just a current list?

    - by zimmer62
    Thinking about all the unique and different peripherals I've owned over the years, from ISA capture cards, to parallel port controlled shutter glasses for 3d games. I've seen many many accessory or computer peripherals come and go. The nostalgia of these things is a lot of fun. I tried to find some sort of historical time-line or list but what mostly turned up is computers themselves. I'm more interested in the mice, scanners, the weird adapters that shouldn't exist, short run very rare products, strange devices from computer shows in the 80's and 90's... Hardware you might find in a geeks basement that would be completely useless now, but was the coolest thing around when it was new. An example would be a drawing tablet I had for my TI-99 computer, or the audio tape player accessory for a C64 which let you save files to audio tapes, An ISA card that did the same for PC's hooked up to a VCR. Remember that IBM-PC Jr upgrade kit, that added a floppy drive, more memory and the AT switch in the back? I'd love to find either a wiki, or a list that has already been assembled which contain many of these weird (or common) accessories. I've had so many over the years I suppose I could start a wiki here if such a list doesn't already exist.

  • What are current options to scan or convert a hand written note to a file on my laptop?

    - by goldenmean
    I wonder how come there are not many options when it comes to scan or convert a device which could be connected to a laptop/desktop, which could - 1] Allow me to write with a digital pen on some special surface, which is connected to my laptop and thus converts my hand written notes to a pdf/jpg/word. (Microsoft's failed attempt at windows based tablet PC in past comes to mind, but not anymore) Any such solution I can use with my laptop? 2] A document scanning device, apart from a flat bed scanner, integrated these days into multi function printers; anything that is portable enough to connect to my laptop?

  • How to echo current document.title with Firefox Vimperator -> autocmd?

    - by shox
    When I try to do this :autocmd LocationChange .* echo document.title the first page that gets displayed makes no echo. If I proceed to the next tab, the title of the last tab gets echoed. Does anybody know how I can get for every landing on the page the title echoed instantly instead of when "leaving" the tab? And it only works every two times. If I go through my tabs 1,2,3,4,5,6,7,8 (next tab) the output will be (being at 1 currently) _blank Title of 1 _ Title of 3 _ Title of 5 _ Title of 7 _ (now being at tab 8) But I want Title of 1 Title of 2 ... Any ideas?

  • How to make the cursor shape dependent on the current Vim mode using iTerm2 on OS X and zsh

    - by i0n
    I am using zsh and iTerm2 to edit with Vim. I really love the integration and portability, and because of that I have chosen not to use MacVim. But.... I can't work out how to get my cursor to change from a block to a line when in Vim's insert mode. I've been lead to believe that it's not possible by standard means, but people seem to think that it is possible using zsh. I've done as much Google searching as I can take without an answer, any help or advice would be greatly appreciated.

  • How to Detect that Current (Bash) Shell is a (Vi/Vim) Subshell?

    - by Jeet
    From inside Vi/Vim, I can type: :shell to drop into a shell. Is there any way to detect that I am in a Vi-spawned subshell? The environmental variable SHLVL is 2, but that does not tell me explicitly that I am in a Vi/Vim-spawned subshell. On OS X, the following variables are also set: MYVIMRC, VIMRUNTIME, VIM. How universal are these? Can I count on these being set in any system, if and only if I am in a Vi/Vim subshell? If not, is there any portable, robust and hopefully efficient way to tell that I am in a Vi/Vim subshell? Thanks.

  • CMD: How do I delete all the contents of all directories (in the current directory) without deleting the directories themselves?

    - by merlin2011
    For example: I'm in the directory: F:\Data Inside this directory, I have four directories: F:\Datadir 22179 22915 23459 23460 These directories have various content, including directories and files. I'm trying to run something like: rmdir /s *\* where I delete all the contents of these numbered directories, while leaving the empty directories. Is there a one-liner that can do this, or do I have to loop through the sub-directories?

  • Simple, current how-to install mod-security on cPanel server?

    - by linux911
    Does anyone have or know of a simple, up to date how to for installing mod-security on cPanel and configuring it after install? Every how to on the web I've found is at least two years old and is based on a mod-security addon function in cPanel which doesn't exist anymore. There are a couple of free add ons to simplify selecting rule files (configserver's for example) but there's no documentation on which rules a cPanel system "should" be using and so on.

  • What are the current options to encrypted a partition on mac os x ?

    - by symbion
    I recently got my laptop stolen with some sensitive informations on it (personal source code, bank details in a secure file, passwords, etc) and I learnt the lesson: encrypt your sensitive data. Now, I am wondering what are the options to encrypt a partition (not an encrypt disk image) ? Aim: The aim is to prevent anyone (except me) to access those data. Requirement 0: The software must be able to encrypt non system partition. Requirement 1: Plausible deniability is required but preventing cold boot attack is however not an absolute requirement (I am not famous enough or have sensitive enough info to have this kind of requirement). Requirement 2 : Software taking advantage of AES hardware encryption are very welcome as I intent to get a Macbook Pro with i7 CPU (with AES-NI enabled instructions). I will have avirtual machine running in the encrypted partition. Requirement 3 : Free or reasonably cheap. Requirement 4 : Software must run on Mac OS X Snow Leopard or Lion. So far, TrueCrypt is the only option I have found. Regards,

  • Clone current host OS to a guest virtual machine.

    - by ProfKaos
    I would like to run a few repeated checks on a setup procedure I am documenting, to verify my document. I would like to somehow create a VM that replicates the environment on my machine, i.e. the host machine, onto a guest VM. Then I can use Windows' System Restore on the guest to start at the point before I commenced the setup procedure and repeat it as many times as required until no more trial-and-error etc. is required to supplement my document. I have Virtual PC and VirtualBox available to install as host environments, running on Windows 7 Professional.

  • How to force a remap of sectors reported in S.M.A.R.T C5 (Current Pending Sector Count)?

    - by edgh
    The S.M.A.R.T C5 value of my Samsung HM640JJ Hard Drive (in an HP Pavilion dv6 laptop) is "yellow status = caution" C5 was 10 yesterday, and it's 21 today. C4 (Reallocation Event Count) = 0 and 05 (Reallocated Sectors Count) = 0 How can I force the firmware to reallocate them? I removed the partitions, recreated them again and formatted the entire drive. I ran chkdsk /r /f I ran the BIOS disk check utility and other diagnose/repair tools

  • Open application in background without losing current window focus. Fedora 17, Gnome 3

    - by Ishan
    I'm running a script in the background which loads an image with feh depending on which application is currently in focus. However, whenever the script opens the image, window focus is lost to feh. I was able to circumvent this by using xdotool to switch back to the application that was originally in focus, but this introduces a short annoying period of time where the focus is switched from feh to the application. My question is this: is there any way to launch feh in the background such that window focus is NOT lost? System: Fedora 17, Gnome 3, Bash Thanks a ton!

  • How do I sync the Solution Explorer with the current File in Visual Studio?

    - by thepaulpage
    When I have an open code file in Visual Studio that I am editing I would like to keep that same file highlighted inside of the solution Explorer so that I know where I am at. What I'd really like is to change the focus to a different code file and the solution explorer to move to the file that I am editing. Further Explanation and example: I have a project with 2 files. Class1 and Class2. I open both files. The focus is on Class1. I click on the Class2 Tab, thereby changing the file that I am editing to Class2. Desired Behavior The solution explorer will highlight Class2.

  • How to run a command in a process that is not a child of the current process?

    - by amicitas
    I am having a library conflict issue with calling an external program from within a interpreted programming environment (IDL). The issue seems to be that since the program I am calling ends up as a child of IDL, libraries are not being reloaded. From within IDL I can launch sub-processes either directly or using a shell. Is there a good way that I can cause my program to be run without ending up as a child process? The only solution I have found so far is to use ssh localhost my_program. This works perfectly but I would like a more direct solution.

  • In Excel how can I sum all the numbers above the current cell?

    - by Mark Meuer
    I want to have a column in Excel that consists of a header, a bunch of numbers, and then have the sum of those numbers at the bottom. I'd like the sum to adapt to the insertion of new numbers above the total. Something like this: Numbers 1 2 5 10 18 Total If I later insert 10 new numbers in the middle of the list, I want the sum to automatically include them. I know the SUM() function can sum a whole column, but if the total is also in that column then it complains about a circular reference. How can I just sum the numbers above the total?

  • How can I get the comment of the current authorized_keys ssh key ?

    - by krosenvold
    Edit: What I really need to know WHICH ssh key from authorized_keys has been used to identify the currently logged on user. According to "man sshd": Protocol 2 public key consist of options, keytype, base64-encoded key, comment. I see that when I use ssh-keygen, the comment is usually the local identity of the user. Is there any way to access this value when I'm on the remote computer ? (Kind of like the SSH_CLIENT shell variable) (Assuming I enforce the comment to be a remote identity of some sort, I would like to log this from a shell-script! This is on ubuntu)

  • Run init.d script in the context of the current user session.

    - by akellehe
    I'd like to run a script in init.d (on Fedora) in the context of the user session I'm logging in as. I have a script called keyboard_deadkeys I wrote to set some deadkeys on my keyboard. The script is very simple: #!/bin/bash /usr/bin/xmodmap /home/julie/keymappings I put it in the directory /etc/init.d so it will run at boot time. It is also in /etc/rc.d/init.d I changed the permissions to a+rwx for good measure. When I boot; the deadkeys aren't set in the user's session. When I then run the script manually; the keys are set. How can I rectify this?

  • "Upgrade current target for ipad" is grayed out (disabled)?

    - by Eric
    I'm trying to create a universal iPhone/iPad app using this method: http://www.enscand.com/roller/enscand/entry/ready_for_ipad which is also described all over the web. My problem is that the "Upgrade current target for iPad" line is grayed out and doesn't appear at all when I right click the target. I'm working on an app that I inherited from someone, and have tried this with an app that I wrote entirely myself (no problems on that one). And yes, I'm sure that I'm selecting the target. Just wondering if anyone has any insight into what checks are being run that would cause this option to be unavailable.

  • How do I zoom an MKMapView to the users current location without CLLocationManager?

    - by Danny Tuppeny
    With the MKMapView there's an option called "Show users current location" which will automatically show a users location on the map. I'd like to zoom into this location without adding a CLLocationManager (this seems silly if the map is already taking care of this). The problem is, I can't find a nice event that fires when the map has figured out the users location, so I don't know where to put the code that will zoom/scroll. I tried using the viewForAnnotation method like this: - (MKAnnotationView *) mapView:(MKMapView *)map viewForAnnotation:(id <MKAnnotation>)annotation { if ([annotation class] == [MKUserLocation class] ) { NSLog(@"UserLocation annotation"); return [map viewForAnnotation:annotation]; } return nil; } However it doesn't fire if the users location is off the screen. Is there a way to be notified when an MKMapView has got the user location so I can zoom in to it, or do I just have to add a CLLocationManager for this?
