  • Screen tail -f window closes immediately

    - by t.heintz
    I have this in my ~/.screenrc file: startup_message off screen -t top 0 top screen -t log 2 tail -f /path/to/application/log/* screen -t action 1 #caption always "%?%F%{.R.}%?%3n %t%? [%h]%?" hardstatus alwayslastline "%-Lw%{= BW}%50>%n%f* %t%{-}%+Lw%<" When I start screen, it opens all three windows, but as soon as I try to switch to window 2, it closes immediately. I would assume there is a problem with the shell and it exits instantly, but I can't find anything wrong with it. I have tried using quotation marks around the path and the entire command, which only leads to "file not found" errors. The command works just fine when I enter it directly into a shell. The screen version is: Screen version 4.00.02 (FAU) 5-Dec-03 Help?

  • alternatives to accessing google reader with oauth?

    - by Dustin Getz
    I'm really new to this oauth stuff. I want to access a user's google reader liked items feed. This blog says that oauth doesn't work (yet) with google reader. The working way seems to be to get the user's google credentials (email, password) directly, and login directly to google. This also gives me access to the rest of their services. Is there a better way, or must the user trust me with their google credentials?

  • Adobe Reader unable to open downloaded file in IE6

    - by chillysapien
    I'm working on a web app that allows users to downloaded dynamically generated PDF files. This works fine in IE8 and Firefox but fails in IE6 with Adobe Reader giving the message "there was an error opening this document. this file cannot be found" If I save the file to disk first then it opens fine in Reader. I've given the file a simple short filename, without spaces so not sure what else to try. Any suggestions are very welcome.

  • Screen Flicker on a black MacBook

    - by sixtyfootersdude
    I have a MacBook Black. For about the last six months I have had a strange screen flicker when I: start my machine and plug in the power cord of my machine This morning when I woke up my computer the screen backlight did not turn on at all. When I held the computer in direct sunlight I could see the screen and I could tell that everything was working normally (other than the backlight). Pressing the screen brightness controls (F2) brought up the brightness panel. The brightness panel informed me that the screen was at maximum brightness. I did a bit of Searching and this is what I found: This post describes how to buy and replace a macbook screen. Do you think that this would solve my problem? Additional info: I am running 10.6.4 I recently upgraded from 10.4. I experienced similar issues in 10.4. I am pretty sure that this is a hardware issue. The problem does not occur when the screen is at a specific angle. It usually only happens at startup/wakeup or when the power is plugged/unplugged.

  • Is there a screen sharing/remote desktop app for mac that lets you use a different host screen resolution?

    - by MarqueIV
    Ok, there are tons and tons of questions about remote desktop for mac and they're all being closed as duplicates. I however am specifically looking for one that will let me use a different resolution than the host, the way you can with Remote Desktop for Windows. For instance, when I connect to my 11" Macbook Air booted into Windows7 from my quad-screen desktop, also booted into Win7 using Microsoft's Remote Desktop Client, it blanks out the screen on the notebook, then virtualizes the video across all four of my desktop's monitors at their native resolutions (2560x1600, 2 x 1920x1200 and 1600x1200) and the notebook now acts as if it has four physical monitors connected to it. All of this from a notebook that only has a 1366 x 768 native resolution. Even when running OS X on the client running RDC, while it doesn't support multi-monitors like its Win counterpart, it still lets me run at the native resolution of the client screen of 2560x1600. Again, it just blanks out the host screen while doing so. However when using Mac's screen sharing, since that is just glorified VNC, it just mirrors what's already on the host's screen, meaning it will always be a single screen with the resolution of 1366x768. This of course makes sense since VNC is a mirroring solution, not a video-virtualizing one like RDC, but it means that on my quad-monitor setup, the remote window isn't even large enough to fill up a single monitor, let alone four (unless you have a client that can scale it up, but that's video scaling. It's still only 1366x768.) So what I'm looking for is if there is a solution on the Mac that lets me do the same thing as RDC in a Win environment. Don't care if I have to pay. I'd gladly pay several hundred dollars for this. I just need that specific feature. Note: People have suggested various VNC clients, but the VNC host still runs at 1366x768 so that will not work here. Ever. Also, people have suggested Synergy/Synergy+/Teleport and such which share the keyboard and mouse, not video. Completely different animal unrelated to what I'm looking for.

  • Howto get exit code of a script started in screen session

    - by Bettina
    Hi folks, I am currently creating a backup script which uses screen to start a backup job with rsync inside a screen session. The backup jobs are started as follows. screen -dmS backup /usr/bin/rsync ... As soon as the rsync job is finished, the screen session is terminated automatically. To make sure, that the backup was successful, I would like to check the exit code of the rsync job but unfortunately I really don't know how to get the exit code after the screen was terminated. Does someone have a good idea how to automatically check, if the rsync job was successful or not? Would be great if someone does. I already thought about using a temp file but like this: screen -dmS myScreen "rsync -av ... ; echo $? /tmp/myExitCode" but this unfortunately does not work. Then I thought about using stderr like in the example below: screen -dmS myScreen "rsync -av ... 2 /tmp/rsync-sterr None of my ideas worked out so far, since stderr is not written when I use the command above. :-( ? Would be great if someone has a good idea or even a solution. Cheers, Bettina

  • Windows 7, Black screen with cursor, impossible to logon

    - by PJC
    First - I have gone through as many possible solutions I've found here and elsewhere. [Edit - to describe the issue in more detail, the PC appears to boot correctly, but instead of the logon screen, I have been getting a black screen WITH the pointer cursor, and it responds correctly to the mouse. Pressing CTL-ALT-DEL brings up the logon screen's background, but with no logon area nor any other content. This screen was at the full resolution before I uninstalled the graphics driver in safe-mode.] I also just ran a full up-to-date AVG scan from boot media. [Edit - the AVG scan, which was updated to today's virus signatures, found no issues at all.] So - steps I've tried: Safe Boot, Restore from before the issue - done, no help. Uninstall the graphics driver - done, now i have a 1024x768 fallback screen, still no way in. sfc /scannow - only doable from Safe boot obviously, but no change. [Edit - booting from restore media, performing a startup repair and...]Restore further back - restored to 2 days ago, and I'd had many reboots since then with no problem. Enable autologin to try to get beyond the login screen - done, doesn't work. It seems the best advice is complete reinstall, but I really don't want to do that because it'll take 3-4 days to add all the apps I use. Some key points to note - in both states - before and after removing the video driver, I always had a mouse cursor on the screen. CTL-ALT-DEL flashes up the login background, but no login info. I can (and often do) reinstall from scratch, but was at a fairly stable state before this, and would prefer not to. -Paul

  • Google Reader API with Objective-C - Problem getting token

    - by JustinXXVII
    I am able to successfully get the SID (SessionID) for my Google Reader account. In order to obtain the feed and do other operations inside Google Reader, you have to obtain an authorization token. I'm having trouble doing this. Can someone shed some light? //Create a cookie to append to the GET request NSDictionary *cookieDictionary = [NSDictionary dictionaryWithObjectsAndKeys:@"SID",@"NSHTTPCookieName",self.sessionID,@"NSHTTPCookieValue",@".google.com",@"NSHTTPCookieDomain",@"/",@"NSHTTPCookiePath",@"NSHTTPCookieExpires",@"160000000000",nil]; NSHTTPCookie *authCookie = [NSHTTPCookie cookieWithProperties:cookieDictionary]; //The URL to obtain the Token from NSURL *tokenURL = [NSURL URLWithString:@"http://www.google.com/reader/api/0/token"]; NSMutableURLRequest *tokenRequest = [NSMutableURLRequest requestWithURL:tokenURL]; //Not sure if this is right: add cookie to array, extract the headers from the cookie inside the array...?

I'm probably not doing it right. I set the dictionary values according to the documentation for NSHTTPCookie.

  • Cron Job that Boots Screen at Start

    - by Pez Cuckow
    I am trying to set up a number of processes that start during boot (servers for games) with the below command as the cron item: @reboot /usr/bin/screen -fa -d -m -S NAME COMMAND However if the server crashes for what ever reason screen closes and the server doesn't get a chance to run it's auto restart (as far as I understand; screen sees no processes in the socket and so closes). Is there a way that I can get around this so screen will sit there even if nothing is running in it?

  • Square Reader Modified to Record Off Old Reel-to-Reel Tape [Video]

    - by Jason Fitzpatrick
    The Square Reader is a tiny magnetic credit card reader that has taken the mobile payment industry by storm. This clever hack dumps the credit card reading in favor of snagging the audio from old music reels. Evan Long was curious about whether the through-the-headphones interface of the Square Reader could be used to read audio data off old magnetic recordings. With a very small modification (he had to bend a metal tab inside the reader to allow the audio tape to slide through more easily) he was able to listen to and record audio off old reels. Watch the video above to see it in action or hit up the link below to read more about his project. iPod Meets Reel [via Make] HTG Explains: What Is Windows RT and What Does It Mean To Me?

  • How to refresh Google Reader cache for a specific domain

    - by Renan
    Brief history domain.com was associated with a blogspot. domain.com changed to an institutional site and features a small code instructing which file should be retrieved by RSS readers. <link rel="alternate" type="application/rss+xml" href="http://domain.tumblr.com/rss" /> Google Reader didn't update the RSS to the new blog. domain.com/blog retrieves the posts correctly because it was never used for that purpose in the older blog. How is it possible to force Google Reader to update the cached information? I tried using another RSS reader and it worked perfectly with the new domain. However, when I tried to follow domain.com in another Google Reader account, it still showed the posts from the older blog. It's been almost a month that the aforementioned changes were made.

  • Using ctrl-arrow keys with PuTTY and screen

    - by kbosak
    I searched and couldn't find a solution for this anywhere. I'm using PuTTY from Windows to connect to various servers where I run bash and screen. It seems bash works fine with ctrl-arrow keys to jump word-to-word on the command line but within screen it's not working. Not in screen, ctrl-left sends "^[OC and ctrl-right is "^[OD". Within screen I instead get "^[[C" and "^[[D", which appears to be the codes for just the left/right arrow keys. Is there any way to get screen to recognize ctrl-arrow keys when using PuTTY? (FYI, I don't remember having this problem when using gnu-terminal in linux instead of PuTTY).

  • 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.

  • Use only external monitor at screen's native resolution

    - by joaoc
    My laptop's screen lamp just died (I can see content on the screen if I point a light at it) and I was using it with an external monitor. I can switch from extended desktop to mirrored mode but, and here is where I need help, the resolutions don't match. The laptop's resolution is 1600x1200 and the external monitor is 1680x1050. I am ok with just using one screen ATM but I would like for it to at least use the native resolution of the external monitor. This is Windows XP and under Monitor settings I only get the resolutions for the original monitor under mirrored mode. How can I force the screen into a resolution not supported by the laptop screen but that is a native resolution for the external monitor?

  • Looking for Google Reader javscript commands for controlling events

    - by JayCrossler
    I've played in the /reader/ui/ code for a few hours now, and couldn't figure this out. Also, I didn't see any exact help when searching StackOverflow. This is really a JavaScript un-obfuscator question. I'm looking for a way to call the obfuscated Google Reader javascript commands... and am having trouble determining what actual function is called when the "Next Items" button is pressed or the spacebar is hit. I've tried using Firebug as well as FireEvents to track it down, but it's just too well hidden. Any ideas? Something that I could type into the URL bar and make it run, something like 'javascript:SH("entries-down", "click");void(0);' Thanks in advance! And, please let me know if it's against Google's terms of service to de-obfuscate their code to view these JavaScript commands.

Here is the problem I am having. For the following RSS feed example, I am having trouble getting it to load the feed. Comes up with an error that it cannot connect. However on my Mac RSS Reader it works fine, so I know the link is good. Any ideas on why it cannot load this particular feed but it can load others fine? http://www.okstate.com/rss.dbml?db_oem_id=200&media=news Thanks.
