I've got a program that takes keyboard input with BufferedReader and readline(), but readline() is blocking so I can't increment any sort of counter to quit the application after a period of inactivity, because the program is just waiting for an input from readline(). Do I need to create multiple threads, where one thread counts down an inactivity timer, or is there some method of using non-blocking keyboard inputs?

Using an ATI Tv wonder HD 600 card, and i'm trying to use it to view an analog signal through the coax input. Normally, I'd tune the tv to channel 3 and be done with it. I'm not really sure how to proceed with it.

Then I checked the microphone and have set it properly and its working now. The details how i made my microphone working is at the following link: [url]

I know it is possible, and I have been trying everything I can find, but I can't seem to get it to work. I went to languages in YaST and enabled Japanese as a second language, and I have tried adding japanese as a secondary keyboard layout under configure desktop-> regional and language settings. I have a little flag in the system tray that I can click to change from US to Japanese, but all that does is change what the punctuation buttons do.

View 3 Replies View Relatedi've written a socket server. when i launch a client, it connects to servers running on various machines on my local network, which then reply to the client with some string messages, and the client exits.
however, when i launch the client repeatedly (say 5 or 6 times in quick succession) the client is unable to bind to its local port. this appears to be because servers are still trying to connect to the client machine's port, even though the client exited and shut the socket down. the actual error i receive is "Error binding socket to 192.168.1.6:44561: Address already in use".
so, is it enough just to shutdown and close a socket? is there some way that in doing so the client machine can send a CONNECTION_REFUSED message to any machine trying to connect to it? i am using PHP, not that that should make much of a difference i hope.
the problem resolves itself after around 20 seconds as the machines trying to connect to the client timeout. i still need to fix this issue though.
The issue I've been having is with Flash on websites; most notably, Livestream's Flash-based browser viewer, and Adult Swim's flash-based games. Clicking works perfectly fine, but the keyboard input is entirely disabled for the Flash area. Text boxes, or game controls, won't respond at all, even when everything else is still working.The only way to input any text into Flash-based text boxes is to write it somewhere else (Firefox's URL or Search bar, or in GEDIT), then copy+paste into the tect box (again, Ctrl+V won't work, only right-clicking and pasting will go through).
I've tried multiple versions of the Adobe Flash player, including the installer directly from Adobe's site, the adobe-flashplugin package in Synaptic, the flashplugin-installer package, and I believe I tried GNASH as well (although I'm not sure if that did anything).I haven't had a chance to attempt to downgrade either one yet, however, nor have I been able to test another browser.I've seen a few other issues of this sort pop up here before, but they've all either gotten no solutions, or they're a year or two old, or they're running into 64-bit-specific issues. Hopefully this is posted in the correct location, and fingers crossed someone has an answer (or better yet, a solution).
I have done a clean install of Ubuntu 10.04 on my laptop. However I don't like Evolution mail client and installed Thunderbird from the repositories. It installed fine and comes up with the wizard to fill account details in but for some reason you can't input anything from the keyboard - it seems greyed out. I tried uninstalling and re-installing but it's still the same. Everything else is fine and working.
View 9 Replies View Relatedhow to change my input language (the way typing in accents affects the output character).
Currently I am on a Brazilian abnt keyboard and an English system (which is what I want), but I am unable to output accented characters - which I sometimes want, when I am not programming.

I just made a script to read out /dev/input/event3 into a file (My keyboard is identified here [ Machine is a laptop which runs on slax-atma distro ]). Then used a hexdump to convert the binary into hex. After that used a gwak script to print out the keys corresponding to each keyboard input. So now when I put this in my rc.local , It is taking down all the keys I press. Including login passwords (In short, each and every keys I press).Isn't this a big security risk, because intruder who has a physical access to my machine or has root password can put this file in rc.local and run a script to mail him all the details like my passwords, account and PIN numbers.
View 14 Replies View RelatedI have a Python script that copies a couple of DLL's and EXE to a directory before running the EXE. It can be a fresh copy or the files can already be in the target directory and are then overwritten. The script uses shutil.copy() to copy the files and that works but as the files are copying processing continues and the script tries to run the files mid copy, causing an error.
I need a way to wait for the files to finish copying before the script continues. Putting the thread to sleep isn't good enough, calling os.system("copy ...") also doesn't work, using os.path.exist() won't work because the file will exist during the copy.
I am using gpg keys with passphrases set to connect to different jabber accounts. When I restore from hibernate I am prompted by two pinentry dialogs for these passphrases. But very often one of these dialogs that is not in focus steals keyboard input from the other dialog. Even worse, they steal keyboard input from fluxbox and other applications and I am unable to do anything until I enter it or click cancel if I do not want to input password right now. How can I forbid pinentry to steal keyboard input and to get it only if it is in focus? I am using pinentry-0.8.0 on Gentoo amd64 with USE="ncurses qt4" (/usr/bin/pinentry is a symlink pointing to pinentry-qt4).UPDATE:After some research, I found that pinentry accepts --no-global-grab option, which, according to the info page, should be used only by developers. Still unsure how to make it default: having#!/bin/zshexec /usr/bin/pinentry-qt4 --no-global-grab $@in place of /usr/bin/pinentry symlink does not work (this script is launched, but option is ignored), if I place it into /usr/local/bin it is not launched at all though I have /usr/local/bin in $PATH before /usr/bin.
View 1 Replies View RelatedBeen a long time since I was on ubuntu again. Saw the new 9.10 version and decided I should take it up again. Only problem is, and I've come across it quite alot, (but never a working solution). That my ctrl key isn't doing anything at all, therefor making every keyboard shortcut (copy/paste/new tab in firefox...etc) not working. It's not compiz his fault, i've had the same issue before i installed it.
Also i tried switching keyboard layouts, when i key press i don't see the ctrl key light up on screen, BUT when i press shift+ctrl, it does Anyone got a clue in how to revive my loving and overused ctrl button again ?
I'm running a 13" white Macbook. The keyboard worked fine, until today. I logged in and half the keys didn't work, the other half were numbers not the letters they were supposed to be. This started after log in, meaning I was able to enter my password properly: The problem starts when gnome boots up.
By copy and pasting, I installed Kubuntu, where the keyboard also works properly, so this is clearly a gnome problem. I haven't ruled out malicious software, which seems like the next step: How do I verify and replace all the software (gnome) that might be corrupted?
I am trying to get the sounds that are played on the Casio CTK-651 keyboard from the keyboard into ubuntu or windows. I can get the signal, but no sound is played back under Windows when it's connected with an AUX-to-USB connector. When I do it with the MIDI-to-USB connector in windows and ubuntu, whenever I press a key, I get what is programmed into LMMS through connecting in a channel. I can't get the piano or guitar or whatever sound that the keyboard is making into the computer. I can upload some video to show what I'm talking about with the aux connector.

View 6 Replies View RelatedI have a very strange problem with Fedora 13 on my home PC. When booting it just hangs at random points in the boot process. When it happend the first time, I thought the PC probably is completed frozen, but then I discovered that hitting the return button got the boot process going on again, but just step by step. That means on every boot I have to keep hitting the return button until gnome starts up, that's very annoying. So for any reason the boot process seems to switch to interactive mode somehow...
I already removed the kernel boot options rhgb and quiet to see, where exactly this happens in the boot process. But as I said, it seems to be completely random. Sometimes it's when "Starting udev", sometimes, when setting up eth card, when starting atd, and so on. It's different every time.
By the way, a similar thing happens when shutting down. It can take up to half an hour until the PC really shuts down. But it's usually going faster if I just keep hitting return after issueing the shutdown command (which actually looks a bit dull). But the PC finally shuts down at some point. That's not the case when booting up. I thought, maybe there's some kind of timeout problem. But even waiting for two hours, the PC does not startup without keeping hammering the return button
