I wish to implement some part of my codes to use the GPU of my graphic card but I have no idea whether GNU as already implemented it (as for OpenMP). I mean, there are PGI Fortran compiler which embedded CUDA but I figure it's not free. I also wonder if that works only with ATI graphic cards or if for instance I can use my Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller.
View 4 RepliesIn Fedora 10, I cannot get to the installer because it shows these messed up strips graphics (its not due to my graphic card, my graphic card is supported 7600gt) in non-quiet install it shows logical errors and i/o errors.

I am looking for a program that would allow me to "cut" a piece out of the picture that would have correct proportions e.g. sides in ration 1:2. What I mean is that I would open the picture, set the proportion of sides, pick my part of the picture and then could resize it. graphic program that does that? I tried several ones and did not succeed. I won't be a problem if its only a one purpose utility.

One of the feature in my application involve changing of hardware setting. This require the user to be root or have administrative right.Before my application enable that feature, I want it to check whether the user is "root" or not, or whether user use "sudo" command to run the application or not, or whether the user has administrative rights or not.What are the codes or library that can do this?
NOTE: Sometimes, advanced linux user may set the user id of root to something else other than 0. So, getuid() may not be helpful in this case.
I need a script that can print some series of strings in colors based in the information of a file, for simplicity let's say it only does:
Code:
#!/bin/bash
printf "e[1;31;32m%-10se[00m" "OK"
When you execute this in the command line it prints a bold green 'OK'. So far so good.
Now, I need to check the output of the script over time using the command watch. The problem then arises. watch seems to ignore the escape codes and just prints:
Code:
[1;31;32mOK [00m
Is there any way to fix this?
If not, how can I check inside the script if it is being executed from a command? (watch in this case) So I can print without color for those cases.
I am doing real time programming in C++, under Linux. I have two processes, let me say A and B. A process is being started periodically, every 5ms. B process is being started every 10ms. The process A is doing data processing. The process B is reading that data and displays it. I am confused about how to run periodically processes. The problem is that the period of process A should be as much as it is possible accurate (5ms). For the process B it isn't so important. I have created independent processes, each in one .cpp file, and I am starting them from bash file. Is that OK? I don't have to make child processes in order to have parallel processes?
View 1 Replies View RelatedSo basically, there is a really cool writing system I have been working on. It could be viewed (for simplification purposes) like an encryption method for the Latin script.
Facts about the writing system:
It has a little over 300 symbols.
It is syllable-driven.
It is highly compositional (eg. "c", "ca", "cae", "ca " and "ci." all map to different symbols - and NOT by overlaying elements)
Symbols have medium graphical complexity (comparable to Korean Hangul, or Japanese Hiragana)
Has a rather complex set of diacritics (~10, some of which can go on any symbol)
Has no ligatures
How transliteration occurs:
Sequences of Latin symbols map to certain symbols. Example below:[G][rou][p ][hu][g.]Characters sequences between "[" and "]" map to a single symbol (so it would take only 5 symbols to write "Group hug.").
How I want it to work:
I would like to have a daemon that: Intercepts all text displayed on the screen.
Converts it to my writing system (changes letter sequences with individual Unicode codes)
Leaves unsupported symbols unchanged.
Displays all the text on the screen using my font and characters intertwined with the fonts and characters left unchanged.
For example, if you take the following line of C++ code:for (i = 1; i <= n; i++)
I would like it displayed like this:[fo][r ]([i ]= [1]; [i ]<= [n]; [i]++)
Bold-symbols should be in my Unicode font with special symbols defined for this writing system, and the rest should be in its original font and encoding. Also, I would like this encoding to hold for display-purposes only. The data in the memory should remain unaffected. This also means real-time adjustments: if I open a text editor (say, from the OpenOffice Suite) and I start typing, I would like to see what I type encoded with my writing system, even though the document actually contains Latin letters. This also means that the symbol immediately before the cursor may change as you type.
I have these but not working.

I developed a protocol "it's a modification of OLSR" for wireless networks, it was with JAVA and I try to simulate it on NS2, I used AgentJ, so in the TCL I did any thing like usual;
set val(chan) Channel/WirelessChannel ;# channel type
set val(prop)Propagation/TwoRayGround ;# radio-propagation model
set val(netif) Phy/WirelessPhy ;# network interface type
[code]....
and I didn't specified the protocol because I attached my nodes to the JAVA class responsible for the protocol, but when I run it generates errors, it claims the protocol to use, so I don't know how proceeding.
I implemented a SSL client using openssl on Linux and it's working fine i am getting response from server...
But my problem is I have a separate thread for each request comes form front end and i have to do SSL communication in each thread, for this i have to create a separate SSL Context for each thread and this is taking too much time hence my transaction is getting delayed
My question is can we implement Persistent SSL connection where i will do SSL Handshake only at the time of application startup and use that connection in all the threads....

I installed ubuntu but when I first tried to login with my correct passwords it goes in a loop and prompt me to log in again. I went to recovery mode and selected safe mode then I was able to log in without any further prompts. As a result of what happened, I unlocked the login screen and changed the setup to allow me to log in automatically and in safe mode only. I am now stuck to login in safe mode only. I tried to unlock the login screen to change to default but no chance. If there is no graphic card in the PC would that have an effect on memory or login?

View 2 Replies View RelatedHow can I implement c_str() for a string class?
View 2 Replies View RelatedI have an interpteter that supports string literals, and the way it works is that the lexer returns the entire string as a single token, with the quotes removed and escape sequences replaced with the literal characters they represent.
I already implemented single-quote strings, they don't interpret any characters specially except for the single quote. I partially implemented double-quoted strings, they already support all the same backslash escape sequences that C does. But I would also want to add variable substitution.
The way it would work is that "${expression}" would interpret the expression (which could just be a variable name) and replace itself with the result. But I have no idea how to do this.
In case it matters, I'm using a hand-written lexer and recursive-descent parser.
I need to implement SAML 1.1 SSO process in Php(Preferred), Java, or C# I am having a very difficult time finding information related to this task. If I could use SAML 2.0 I would be home free with "Simple Saml Php" but I am not that lucky. Would the process be as simple as building the SAML in XML then submitting it with a SoapClient? According to the Docs I've read that would appear to work.

I'm implementing a TCP protocol. TCP implementation requires to send packets continuously and if the receiver doesnt respond after a particular interval of time it should resend the packet again. I need some method to implement a timer expiry function. How can I implement it? Should i implement threads (If yes can you please give a sample)? or is there any better method?
