  • How to receive a datastream from a device on your computer, in C#

    - by WebDevHobo
    I plan to build a small audio-recorder app in C#. My laptop has a built in Microphone that's always active, so I want to use that as an early-stage test. I would simply start recording, save the file as a .wav or even use the LAME dll to make it into an MP3. The problem is, I don't know how to contact that microphone. Do I use a library that can detect a device, or do I just catch a stream of bytes from the port that the device is on? I don't have any experience with receiving data from connected devices. I suppose that I'll need to enter all the data into a byte array and then Serialize that into a WAV file, but I'm not sure. Can I get some pointers on this subject?

  • Do you think the AI industry will ever come back?

    - by Isaiah
    I just spent some time reading about the collapse of the AI industry and realized a lot of the reason it failed was because technology was slow to catch up with their theories on when it would be available. I also read that it is believed computers that will be able to emulate human synapses may be made round 2015-2025. It's 2010 now and were getting pretty close to that time frame. I was wondering if anyone thinks that the AI industry will return as the technology lands? And if so, will it change the language market? Could Lisp like languages suddenly experience a burst of growth if it does? Idk I just thought it was interesting thinking about it.

  • How to prevent WD MyBook Live Duo from going to sleep?

    - by Chris Pietschmann
    I have an issue of my WD MyBook Live Duo going into some kind of low power standby mode when it hasn't been accessed for awhile. When I try accessing the drive it takes a minute or two to become responsive. When this happens Windows Explorer says the drive is unavailable. If I'm accessing the drive regularly throughout the day then this issue doesn't occur. Does anyone know of a way to make the drive more readily accessible on demand?

  • Can't see any entries on "File Types" tab on Windows 7's Desktop Search

    - by Mick
    For some reason, Windows Desktop Search (included with Windows 7.0) now no longer shows any file types on the "Advanced Options" dialog box. Any ideas on how to fix this? WDS claims to be indexing...but I'm not sure what it's actually indexing right now. I should also add that when I try to add a file type, nothing shows up or is ever actually added. If I login as a different user on the same system, everything appears normally.

  • Custom settings with PHP on Nginx

    - by miki
    I have multiple websites setup using Nginx and Apache, but when I try to add a vhost based PHP directive using fastcgi_param PHP_VALUE , the value get added to all of my vhosts. Checking the value of the PHP parameter from PHP-CLI remain the actual one for whole server. e.g. I used fastcgi_param PHP_VALUE "memory_limit=512M" for a domain based nginx config, but it will be propagated to all domains on server. The 'php -i | grep memory_limit' show 128M though Not sure what I am missing

  • Better Java method Syntax? Return early or late? [closed]

    - by Gandalf
    Duplicate: Should a function have only one return statement? and Single return or multiple return statements? Often times you might have a method that checks numerous conditions and returns a status (lets say boolean for now). Is it better to define a flag, set it during the method, and return it at the end : boolean validate(DomainObject o) { boolean valid = false; if (o.property == x) { valid = true; } else if (o.property2 == y) { valid = true; } ... return valid; } or is it better/more correct to simply return once you know the method's outcome? boolean validate(DomainObject o) { if (o.property == x) { return true; } else if (o.property2 == y) { return true; } ... return false; } Now obviously there could be try/catch blocks and all other kinds of conditions, but I think the concept is clear. Opinions?

  • In FLEX, How can you stop ENTER Key from my Alert being caught by the control that initiated the Al

    - by WeeJavaDude
    I am having an issue where I show an AlertBox message when the user hits ENTER and the focus is in a text area. The pop up works fine, but when the user hits enter the Alert closes as expected, but the TextArea listener receives the ENTER event from the Alert and pops the dialog up again. I have tried a number of ways to catch and eat the event but so far I have not been lucky. Is there way to accomplish this? public function init():void { myTextInput.addEventListener(KeyboardEvent.KEY_UP, handleKeyStrokes); } public function handleKeyStrokes(evt:KeyboardEvent):void { if(evt.keyCode == Keyboard.ENTER) { myAlert = Alert.show("This is a test and only a test", "Title", 4, null, alertCallBack); } } <mx:TextInput id="myTextInput" left="600" top="10"> </mx:TextInput>

The package installs fine, but when I try to run it lkl -l -k /usr/share/lkl/keymaps/us_km -o ./kbd.log & it hogs the CPU usage to 50% and never logs a keystroke (in fact the kbd.log file is never created) Any clues? TIA

  • unable to mount disks in usb dvd drive

    - by Arcath
    I have 2 USB DVD drives. One that I borrowed from work which I have been testing with which works fine for me, which is why I brought one of myself. When I try and mount my new dvd drive this happens: [18:06:45][arcath@londinium][~] sudo mount /dev/sr0 /mnt/dvd/ mount: special device /dev/sr0 does not exist /dev/sr0 is only in the list when the drive is attached and it works on other machines using the same cables so it must be something with my server. The server is running Ubuntu 10.10 server

  • Up-to-date Comparison of High-Speed USB Flash Drives

    - by Zoredache
    I am looking for comparison of the performance of USB flash drives. I have found several older comparisons, but I am trying to find a more up-to-date comparisons that apply to the larger storage sizes (32-128GB). I can try looking up the specs of various drives, but vendors have been known to exaggerate, or use numbers that are on accurate in tests that do not reflect actual usage. I was hoping to find 3rd party site which had perform testing.

  • Creating a PHP call home "time bomb" to protect my interests

    - by RC
    Hi everyone, I produced a PHP web app for a client some months back that is hosted on their own server. I have still not been paid for this work, and they are giving me the runaround. It turns out that I still have remote admin access to their server, so I can make code changes. What I was thinking of doing was to move the core kernel off-site onto one of my own servers, and program in some kind of callback or include that gets the kernel (critical functions) from my server. Give it two weeks or so for their backups to catch this change, and then pull the plug and exercise leverage. If I do this, they will pay immediately, because the site is a critical one for a very large and influential client of theirs. What is the most effective and easiest way of doing this? What code do I use? Thanks for any pointers.

  • Java String to SHA1

    - by AeroDroid
    I'm trying to make a simple String to SHA1 converter in Java and this is what I've got... public static String toSHA1(byte[] convertme) { MessageDigest md = null; try { md = MessageDigest.getInstance("SHA-1"); } catch(NoSuchAlgorithmException e) { e.printStackTrace(); } return new String(md.digest(convertme)); } When I pass it toSHA1("password".getBytes()), I get "[?a?????%l?3~??." I know it's probably a simple encoding fix like UTF-8, but could someone tell me what I should do to get what I want which is "5baa61e4c9b93f3f0682250b6cf8331b7ee68fd8"? Or am I doing this completely wrong? Thanks a lot!
