  • Can I get the amount of time for which a key is pressed on a keyboard

    - by Adi
    Dear all, I am working on a project in which I have to develop bio-passwords based on user's keystroke style. Suppose a user types a password for 20 times, his keystrokes are recorded, like holdtime : time for which a particular key is pressed. digraph time : time it takes to press a different key. suppose a user types a password " COMPUTER". I need to know the time for which every key is pressed. something like : holdtime for the above password is C-- 200ms O-- 130ms M-- 150ms P-- 175ms U-- 320ms T-- 230ms E-- 120ms R-- 300ms The rational behind this is , every user will have a different holdtime. Say a old person is typing the password, he will take more time then a student. And it will be unique to a particular person. To do this project, I need to record the time for each key pressed. I would greatly appreciate if anyone can guide me in how to get these times. Editing from here.. Language is not important, but I would prefer it in C. I am more interested in getting the dataset.

  • Weird problem with PHP mail() under Linux.

    - by Vilx-
    This is the case when it "works on my machine". Except that my machine is Windows, and the target is some sort of Linux. The idea is that the mail() function puts a newline between the MIME-Version and Content-Type headers, thus breaking the whole thing. Here's the code, simpliefied as much as possible: <?php $HTMLPart = chunk_split(base64_encode('<html><body style="color: red">Test.</body></html>')); $PlaintextPart = chunk_split(base64_encode('>>> TEST <<<')); $Headers =<<<AKAM From: "My Test" <[email protected]> Reply-To: [email protected] MIME-Version: 1.0 Content-Type: multipart/alternative; boundary="9-1410065408-1410065408=:27514" AKAM; $Body =<<<AKAM This is a multi-part message in MIME format. --9-1410065408-1410065408=:27514 Content-Type: text/plain; charset="windows-1252" Content-Transfer-Encoding: base64 $PlaintextPart --9-1410065408-1410065408=:27514 Content-Type: text/html; charset="windows-1252" Content-Transfer-Encoding: base64 $HTMLPart --9-1410065408-1410065408=:27514-- AKAM; echo 'Try 3: '; echo mail('[email protected]', 'Testmail', $Body, $Headers) ? 'WIN' : 'FAIL'; ?>

  • Do you disable SELinux?

    - by manicmethod
    I want to know if people here typically disable SELinux on installations where it is on by default? If so can you explain why, what kind of system it was, etc? I'd like to get as many opinions on this as possible.

  • Add device driver to Windows CE 6.0 through Platform Builder

    - by Luís Mendes
    I'm trying to add a device driver to a Windows CE 6.0 image that I'm creating through Platform Builder. The driver in question, for the VIA 6656 chipset (used in many USB Wi-Fi adapters/dongles), is available in the manufacturer's website and consists of several files: .PDB, .REG, .BIB, .DLL, .MAP and .REL. I understand that the REG file must be imported in my OSDesign.reg, the BIB file to my OSDesign.bib and the DLL must be placed in the /Windows folder of my image. What I don't understand is what to do with the remaining files (PDB, MAP and REL). Could anyone assist me in this matter? Thank you in advance!

  • MySQL nested CASE error I need help with?

    - by AK
    What I am trying to do here is: IF the records in table todo as identified in $done have a value in the column recurinterval then THEN reset date_scheduled column ELSE just set status_id column to 6 for those records. This is the error I get from mysql_error() ... You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'CASE recurinterval != 0 AND recurinterval IS NOT NULL THEN SET date_sche' at line 2 How can I make this statement work? UPDATE todo CASE recurinterval != 0 AND recurinterval IS NOT NULL THEN SET date_scheduled = CASE recurunit WHEN 'DAY' THEN DATE_ADD(date_scheduled, INTERVAL recurinterval DAY) WHEN 'WEEK' THEN DATE_ADD(date_scheduled, INTERVAL recurinterval WEEK) WHEN 'MONTH' THEN DATE_ADD(date_scheduled, INTERVAL recurinterval MONTH) WHEN 'YEAR' THEN DATE_ADD(date_scheduled, INTERVAL recurinterval YEAR) END WHERE todo_id IN ($done) ELSE SET status_id = 6 WHERE todo_id IN ($done) END The following mySQL statement worked just fine before I revised like above. UPDATE todo SET date_scheduled = CASE recurunit WHEN 'DAY' THEN DATE_ADD(date_scheduled, INTERVAL recurinterval DAY) WHEN 'WEEK' THEN DATE_ADD(date_scheduled, INTERVAL recurinterval WEEK) WHEN 'MONTH' THEN DATE_ADD(date_scheduled, INTERVAL recurinterval MONTH) WHEN 'YEAR' THEN DATE_ADD(date_scheduled, INTERVAL recurinterval YEAR) END WHERE todo_id IN ($done) AND recurinterval != 0 AND recurinterval IS NOT NULL

  • Android playing Video data from a custom network stream?

    - by Cinar
    Does Android MediaPlayer can only work with file sources? I would like play media (video) from a network stream, but the stream comes in a non-standard protocol, so I have to somehow feed Android MediaPlayer with the data only. Is there anyway to do that? I found a few web pages suggesting using a temporary file for the buffered media data etc. but I would like to minimize the I/O usage as much as I can, so I'm looking for a API only solution if there is any? how about JNI? but looks like the permissions going to be an issue with that also.

  • Embedding Python and adding C functions to the interpreter

    - by monoceres
    I'm currently writing an applications that embedds the python interpreter. The idea is to have the program call user specified scripts on certain events in the program. I managed this part but now I want the scripts to be able to call functions in my program. Here's my code so far: #include "python.h" static PyObject* myTest(PyObject* self,PyObject *args) { return Py_BuildValue("s","123456789"); } static PyMethodDef myMethods[] = {{"myTest",myTest},{NULL,NULL}}; int main() { Py_Initialize(); Py_InitModule("PROGRAM",myMethods); PyRun_SimpleString("print PROGRAM.myTest()"); Py_Finalize(); } Thanks!

  • Android strace in Real device

    - by Martin Solac
    I have the following situation, I want to monitor the system calls on Android phones so I made an script to do that. With Android Emulator works perfectly (writes the traces of the application in a specific file on my Ubuntu). The problem is when I attach a real phone to analyze it, it says the following in the result file: ptrace attach failed: Operation not permitted I'm using this code to get it, but I don't understand why it works on the emulator and not in the rooted real device. This is the comand I use in perl: system("$dirTools/adb -s $Device shell strace -p $PID[1]>$dirRecordDataSet/$Date/$appName &"); Any suggestion? Thanks in advance

  • gcc architecture question

    - by Andy
    Hi, I'm compiling my program with architecture set to -mtune=i386 However, I'm also linking statically against several libs (libpng, zlib, jpeglib, vorbisfile, libogg). I've built these libs on my own using configure and make, so I guess these libs were built with architecture being set to my system's architecture which would be i686. But I don't want that! I want my program to run on i386, too, so I need to make sure that all these libs that I'm statically linking against are built for i386, too. So my question: Is there a convenient way to build libpng/zlib/jpeglib/vorbisfile/libogg etc. for i386 or do I have to modify all of their makefiles manually and make sure that -mtune is set to i386? Thanks for help! Andy

  • X11 and ARGB visuals: does DefaultDepth() never return 32?

    - by Andy
    Hi, I'm establishing a connection to the X server like this: display = XOpenDisplay(NULL); screen = DefaultScreen(display); depth = DefaultDepth(display, screen); I'm wondering now why "depth" is always set to 24. I would expect that it is only 24 when compositing is turned off, but in fact, it is still 24 even when I turn on compositing. So in order to get a 32-bit ARGB visual I need to call XGetVisualInfo() first with depth set explicitly to 32. Now to my question: Will DefaultDepth() generally never return more than 24 or is it just on my system? (my graphics board is somewhat dated...). I know that it could return 15, 16 or even 8 for a CLUT display but can it return 32? Or do I always have to use XGetVisualInfo() first to get a ARGB 32-bit visual? Thanks, Andy

  • ps: Clean way to only get parent processes?

    - by shkschneider
    I use ps ef and ps rf a lot. Here is a sample output for ps rf: PID TTY STAT TIME COMMAND 3476 pts/0 S 0:00 su ... 3477 pts/0 S 0:02 \_ bash 8062 pts/0 T 1:16 \_ emacs -nw ... 15733 pts/0 R+ 0:00 \_ ps xf 15237 ? S 0:00 uwsgi ... 15293 ? S 0:00 \_ uwsgi ... 15294 ? S 0:00 \_ uwsgi ... And today I needed to retrieve only the master process of uwsgi in a script (so I want only 15237 but not 15293 nor 15294). As of today, I tried some ps rf | grep -v ' \\_ '... but I would like a cleaner way. I also came accross another solution from unix.com's forums: ps xf | sed '1d' | while read pid tty stat time command ; do [ -n "$(echo $command | egrep '^uwsgi')" ] && echo $pid ; done But still a lot of pipes and ugly tricks. Is there really no ps option or cleaner tricks (maybe using awk) to accomplish that?

It looks like the issue is due to the following line not working properly: builtin eval export $previousFilenameVar=$filename I have a some theories to explain why: in the original code, functions are declared and exported as readonly which makes them unable to modify global variable. I removed readonly declarations in the above sample, but probleme persists. Function calls are performed in $() which should make them run into seperated shell instances so variable modified are not exported to the main shell But I cannot manage to find a workaround to this issue... Any help is appreciated, thanks in advance!

  • What algorithm should I use for encrypting and embedding a password for an application?

    - by vfclists
    What algorithm should I use for encrypting and embedding a password for an application? It obviously is not bullet proof, but it should be good enough to thwart someone scanning the database with a hex editor, or make it hard for someone who has the skills to use a debugger to trace the code to work out, either by scanning for the encrypted password, or using a debugger to run through the decryption code. Object Pascal would be nice. /vfclists

  • How does py2exe actually -and simply explained- work? :)

    - by sandra
    Hi folks, I have a c++ app that calls another python one (bundled into an exe with py2exe) So I have 2 apps. So I was wondering: What if my c++ did what py2exe does? i.e. embed the python app in the c++ one. This way I won't depend on py2exe and its configurations nighmares (yes, it has some) Hence my questions: how does py2exe work (so I can do its job with my c++ app) What about just embedding the whole python app with the c++? I read the python doc about embedding, did an example (a very simple one that does PyRun_SimpleString) but what about a whole python app with tons of modules? (zipimport maybe?) I'd love to hear how you'd do that. Thanks a lot! :)

  • per process configurable core dump directory

    - by Hanno Stock
    Is there a way to configure the directory where core dump files are placed for a specific process? I have a daemon process written in C++ for which I would like to configure the core dump directory. Optionally the filename pattern should be configurable, too. I know about /proc/sys/kernel/core_name_format, however this would change the pattern and directory structure globally. Apache has the directive CoreDumpDirectory - so it seems to be possible.
