  • Exclude an input language from Alt+Shift/Ctrl+Shift switching cycle on Windows

    - by Headcrab
    I have 3 input languages installed on my Windows 7: English, Russian and Japanese. So when I switch between them by Ctrl+Shift, they go like English - Russian - Japanese - English - ... I don't use Japanese much, but still need it occasionally. Is there a way to somehow exclude it from the "Ctrl+Shift cycle" without uninstalling it from the system? E. g. Ctrl+Shift will be like English - Russian - English - ..., while I still could switch to Japanese by a dedicated keyboard shortcut, say, Ctrl + 3? That extra Ctrl+Shift to go through Japanese just to switch between English and Russian is very annoying, and using Ctrl+1, Ctrl+2, Ctrl+3 for each input language isn't very ergonomic, either.

  • A way to auto cycle (close) through all screen sessions

    - by JBWhitmore
    I frequently use screen when I log into the interactive nodes to a supercomputer that I have access to -- and I often run things and move on. There are about 20 separate nodes that I can log into; and if I check any one of them I'll have something like 4 detached sessions. Each of those sessions will have maybe 5 screen sessions within that. Is there a quick way to cycle through all of these and close them down if they are not running any processes? My current process is to screen -ls and then screen -r #### then type exit until I'm back to the base screen.

  • OS X SnowLeopard menubar icons appear/disappear in 8 second cycle

    - by Robot
    I just bought a new Mac Mini, and used Migration Assistant to move a user from an iMac to it. All went well, except a very strange behavior... the default OS X menubar icons like time, spotlight, etc (but NOT user installed app icons like dropbox or xmarks) appear and disappear in a very regular 8 second cycle. They appear for about 2 seconds, and then disappear for about 6. This is a screenshot with the icons, and this is a screenshot without them. This is very annoying and I have not found anything online with similar symptoms. Any ideas?

  • Cycle in Eclipse

    - by Sebi
    If I open two Java projects in Eclipse which depend on each other, I have to add dependencies between these two projects in the Build Path (Properties - Java build path). This works fine for one way, but why doesn't allow Eclipse to set the dependencies vice versa? The following error message occurs: A cycle was detected in the build path of project 'A' and A cycle was detected in the build path of project 'B' I know what's causing this error but i wonder why exactly this isn't allowed. Thanks.

  • avoid NullPointerException at the first cycle

    - by user1508419
    I have this piece of code: EventSnapshot snapshotEvent = new EventSnapshot(); EventSnapshot currentEvent = new EventSnapshot(); do { ... currentEvent.setContent(in_stats); ... if(!snapshotEvent.equals(currentEvent)) snapshotEvent.setContent(in_stats); } while(true); At the first cycle I get a NullPointerException because obviously the object snapshotEvent is empty. At the second cycle this doesn't happen.how can avoid this problem?

  • How does cross domain authentication work in a firewalled environment?

    - by LVLAaron
    This is a simplification and the names have been changed to protect the innocent. The assets: Active Directory Domains corp.lan saas.lan User accounts [email protected] [email protected] Servers dc.corp.lan (domain controller) dc.saas.lan (domain controller) server.saas.lan A one way trust exists between the domains so user accounts in corp.lan and log into servers in saas.lan No firewall between dc.corp.lan and dc.saas.lan server.saas.lan is in a firewalled zone and a set of rules exist so it can talk to dc.saas.lan I can log into server.saas.lan with [email protected] - But I don't understand how it works. If I watch firewall logs, I see a bunch of login chatter between server.saas.lan and dc.saas.lan I also see a bunch of DROPPED chatter between server.saas.lan and dc.corp.lan. Presumably, this is because server.saas.lan is trying to authenticate [email protected] But no firewall rule exists that allows communication between these hosts. However, [email protected] can log in successfully to server.saas.lan - Once logged in, I can "echo %logonserver%" and get \dc.corp.lan. So.... I am a little confused how the account actually gets authenticated. Does dc.saas.lan eventually talk to dc.corp.lan after server.saas.lan can't talk to dc.corp.lan? Just trying to figure out what needs to be changed/fixed/altered.

  • Automatically clear cache of all major browsers installed

    - by MorganTiley
    I would like a way to clear cache from all my locally installed browsers - quickly and easily. A simple utility that would ask "Clear all browser caches?" with Yes/No. Just the major browsers -IE, Firefox, Safari, Chrome and optionally Opera I understand CCleaner can do this but it is not as simple as I would like (as it has other functions as well). I tried googling/stacking and couldn't find anything.

  • How to clear Windows disk read cache?

    - by Sebastiaan Megens
    For performance testing I need to clear Windows' disk read cache. I tried googling but I couldn't find anything other than rebooting or other manual stuff. Before I give in and do that, I'd like to know if anyone knows of a way to clear Windows disk read cache. I'm testing on Windows 7, but I'm also interested in Windows XP solutions.

  • clear IP address of Ethernet interface

    - by jackhab
    What is the Linux command to clear IP address of an interface without bringing it down and/or restarting network services. Seems strange ifconfig is able to change IP address but has no option to clear it, or am I wrong? EDIT:As simple as ifconfig eth0 0.0.0.0. They should have put it in the man

  • nginx rewrite or internal redirection cycle

    - by gyre
    Im banging my head against a table trying to figure out what is causing redirection cycle in my nginx configuration when trying to access URL which does not exist Configuration goes as follows: server { listen 127.0.0.1:8080; server_name .somedomain.com; root /var/www/somedomain.com; access_log /var/log/nginx/somedomain.com-access.nginx.log; error_log /var/log/nginx/somedomain.com-error.nginx.log debug; location ~* \.php.$ { # Proxy all requests with an URI ending with .php* # (includes PHP, PHP3, PHP4, PHP5...) include /etc/nginx/fastcgi.conf; } # all other files location / { root /var/www/somedomain.com; try_files $uri $uri/ ; } error_page 404 /errors/404.html; location /errors/ { alias /var/www/errors/; } #this loads custom logging configuration which disables favicon error logging include /etc/nginx/drop.conf; } this domain is a simple STATIC HTML site just for some testing purposes. I'd expect that the error_page directive would kick in in response to PHP-FPM not being able to find given files as I have fastcgi_intercept_errors on; in http block and nave error_page set up, but I'm guessing the request fails even before that somewhere on internal redirects. Any help would be much appreciated.

  • Track kids browsing history even when they know how to clear it manually

    - by Darren Newton
    I have a colleague with two teenage boys (yes, cue cliche's about 'I have this friend see...') He's currently having issues with them browsing pr0n and wants to do a little spying on their browsing (I'm staying clear of the philosophies/ethics on this.) The kids are savvy enough to clear their browsing history when they're done. As I'm his goto for IT he has asked me if there is a way to keep a hold of the browsing history. The family uses Macs, and the kids surf with Safari. I know that browsing history is kept here ~/Library/Safari/History.plist. I figure there should be a way to write either an AppleScript or other script (Python/Ruby/Bash) that can backup this file to a different location (/opt/local/history, etc.) Since the kids know to clear their history when they're done should the file be periodically backed up with something similar to a cron job or something like Hazel? While that could work it seems like it would create a ton of little incremental backups. Or is it possible to 'watch' ~/Library/Safari/History.plist and incrementally add changes to a backup file (saving a diff so to speak) but not lose any data? Any ideas/solutions appreciated. UPDATE/EDIT: Got the word from concerned dad that the oldest uses Firefox on a different PC, so the OpenDNS solution (preferably at the router level) is the best answer so far as it would capture usage for the whole house.

  • IIS7 - Lock Violation error, HTTP handlers, modules, and the <clear /> element

    - by Daniel Schaffer
    I have an ASP.NET site that uses its own set of HTTP handlers and does not need any modules. So, in IIS6, all I had to do was this in my web.config: <httpModules> <clear /> </httpModules> However, if I try to do the same in the system.webServer area for IIS7, I get a 500 error when I try to view the site, and in IIS manager when I try to view the handler mappings, I get a popup box with the message: There was an error while performing this operation Details: Filename: \?\C:\Sites\TheWebSiteGoesHere\web.config Line number: 39 Error: Lock violation Line 39 is where the <clear /> element is. Some googling led me to a solution involving running this command: %windir%\system32\inetsrv\appcmd.exe unlock config -section:system.webServer/modules ...but that did not solve the problem.

  • How to clear the REPLACEBATT state from APC UPS after hot-swapping the battery

    - by Hubert Kario
    I replaced a battery in APC SmartUPS by hot-swapping. While the swap was all right and didn't disturb connected computers, the "Battery failed" LED on the front face kept glowing. I tried to use apctest from apcups package. Turned off the daemon and run self test (first changing BATTDATE in EEPROM). The test run fine but didn't clear the REPLACEBATT status or the glowing LED. How to clear the failed battery state without powering the UPS and connected equipment down?

  • MS Clear Screen Saver doesn't work

    - by ufoq
    I have a problem with really exotic thing - Microsoft Clear Screen Saver. As it's name suggests, it's a screen saver, that's transparent (MS posted it as a part of W2k Resource Kit). When you move the mouse/hit a key, the "lock" dialog appears. I would like to use this to view servers desktops without need to log in. I tested it on my XP's, and it works flawlessy. But on W2K3 servers it doesn't work. After the screensaver timeout, the error message is displayed: "The Clear Screen Saver cannot display the user desktop after the workstation has been locked"

  • jQuery Cycle plugin IE6/7 issues

    - by Aaron Moodie
    I've implemented a slideshow using the Cycle plugin, which is working in all browsers except IE6&7, where the images just show up in a list, and the #page_copy div is not hiding. I've been going through the code all day without any luck, and not exactly sure how or what I should be looking for. What would be the best way to go about debugging this issue? I know that the #page_copy div is hiding when I remove the rest of the code, and I've tried the reverse (which had no result) <script type="text/javascript" charset="utf-8"> jQuery.fn.fadeToggle = function(speed, easing, callback) { return this.animate({opacity: 'toggle'}, speed, easing, callback); }; $(document).ready(function() { $('#page_copy').hide(); $('a#info_close_button').click(function() { $('#page_copy').fadeOut(200); return false; }); $('a#info_button').click(function() { $('#page_copy').fadeToggle(200); return false; }); }); $(window).load(function() { // vertically center single image var $image_cnt = $("#images > img").size(); if($image_cnt < 2) { var $single_img = $("#images").children(':first-child'); var h = $single_img.height(); $single_img.css({ marginTop: (620 - h) / 2, }); $(".next").css("display","none"); $(".prev").css("display","none"); } }); // wait until images have loaded before starting cycle $(window).load(function() { // front image rotator $('#images').cycle({ fx: 'fade', speed: 300, next: '.next', prev: '.prev', containerResize: 0, timeout: 0, delay: -2000, before: onBefore }); }); // hide all but the first image when page loads $(document).ready(function() { $('#images img:gt(0)').hide(); }); // callback fired when each slide transition begins function onBefore(curr,next,opts) { var $slide = $(next); var w = $slide.width(); var h = $slide.height(); $slide.css({ marginTop: (620 - h) / 2, marginLeft: (650 - w) / 2 }); }; </script>

  • How to cycle through matrix blocks?

    - by luiss
    I have some matrix which I want to cycle through blocks, the matrix could be of many different sizes, but I can know the size, is there a way to fast cycle through blocks? i.e: to fast output the indexes of the blocks, suppose a matrix of 4*4 I should have: Block1: (0,0),(0,1)(1,0)(1,1) Block2: (0,2),(0,3)(1,2)(1,3) Block3: (2,0),(2,1)(3,0)(3,1) Block4: (2,2),(2,3)(3,2)(3,3) Where the indexes are (row,col). For blocks I mean a submatrix of size sqrt(matrixSize)* sqrt(matrixSize) where matrix is a matrix of matrixSize*matrixSize. For example a matrix of 4*4 has 4 blocks of 2*2, a 9*9 has 9 blocks of 3*3... I'm workdeing in C, but I think that the pseudocode is useful also, I only need the loop on the indexes... Thanks

  • On mobile is there a reason why processes are often short lived and must persist their state explicitly?

    - by Alexandre Jasmin
    Most mobile platforms (such as Android, iOS, Windows phone 7 and I believe the new WinRT) can kill inactive application processes under memory pressure. To prevent this from affecting the user experience applications are expected to save and restore their state as their process is killed and restarted. Having application processes killed in this way makes the developers job harder. On various occasions I've seen a mobile app that would: Return to the welcome screen each time I switch back to it. Crash when I switch back to it (possibly accessing some state that no longer exists after the process was killed) Misbehave when I switch back to it (sometimes requiring a restart or tasks killer to fix) Otherwise misbehave in some hard to reproduce way (e.g. android service killed and restarted at the wrong time) I don't really understand why these mobile operating systems are designed to kill tasks in this way especially since it makes application development more difficult and error prone. Desktop operating systems don't kill processes like that. They swap out unused pages of memory to mass storage. Is there a reason why the same approach isn't used on mobile? Mobile hardware is only a few years behind PC hardware in term of performance. I'm sure there are very good reasons why mobile operating systems are designed this way. If you can point me to a paper or blog post that explain these reasons or can give me some insight I'd very much appreciate it.
