• Jave JIT compiler compiles at compile time or runtime ?

  - by Tony

  From wiki: In computing, just-in-time compilation (JIT), also known as dynamic translation, is a technique for improving the runtime performance of a computer program. So I guess JVM has another compiler, not javac, that only compiles bytecode to machine code at runtime, while javac compiles sources to bytecode,is that right?

• using qsub (sge) with multi-threaded applications

  - by dan12345

  i wanted to submit a multi-threaded job to the cluster network i'm working with - but the man page about qsub is not clear how this is done - By default i guess it just sends it as a normal job regardless of the multi-threading - but this might cause problems, i.e. sending many multi-threaded jobs to the same computer, slowing things down. Does anyone know how to accomplish this? thanks. The batch server system is sge.

• Modifying text files and executing programs with command line parameters in c# or c++ on Linux

  - by Robert Harvey

  I have a need to create a utility in Suze Linux. The utility will make modifications to some text files, and then use the information in those text files to program a device in the computer using a different executable which accepts command line parameters. I am fluent in c#, but have never worked with Linux. Should I take the time to learn Gnu C++ to do this, or install Mono? How would I execute the programming utility and pass it command line parameters?

• Reopening serial port fails if not closed properly with CloseHandle

  - by superg

  I am working with USB device on Windows that is seen as a virtual serial port. I can communicate with the device using CreateFile and ReadFile functions, but in some cases my application does not call CloseHandle (when my application in development crashes). After that all calls to CreateFile fail (ERROR_ACCESS_DENIED), and the only solution is to log in to my computer again. Is there any way to force closing the open handle (or reopening) programmatically?

• Can an algorithmic process ever give true random numbers ?

  - by Arkapravo

  I have worked with random functions in python,ruby, MATLAB, Bash and Java. Nearly every programming language has a function to generate Random numbers. However, these apparently random sequences are termed as pseudo-random number sequences as the generation follows a deterministic approach, and the sequence seems to repeat (usually with a very large period). My question, can an algorithmic/programming process ever yield true random numbers ? The questions probably is more of theoretical computer science than just programming !

• How to secure the communication between an MSSQL database and a c# administrative tool?

  - by citronas

  How can I secure the communication between a C# programm running locally on my computer and a MSSQL Server in a hosted environment? I have an asp.net application that is secured by SSL encryption. So using the asp.net from an open wlan connection is no problem. How can I achieve the same kind of encryption for my administrative tool? Would it be best to write a service? But how would that connection to the service be secured?

• HTML5 applicationCache in local development

  - by jesper

  I'm experimenting with application cache based on this example: http://html5demos.com/html5demo.manifest This example works fine in ff, but when I create analogous site (almost identical) I get only status "UNCACHED (numeric value 0) -- The ApplicationCache object's cache host is not associated with an application cache at this time." I work on xampp and I've set correct mime-type. When the page is loading ff "is asking to store data on your computer for offline use" and when I show Tools - Options - Advanced - Network - Offline data there is localhost but with 0B size.
