Hi, I would like to experiment with ideas about distributed file synchronization/replication. To make it efficient when the user is working, I would like to implement some kind of daemon to monitor changes in some directory (e.g. /home/user/dirToBeMonitored or c:\docs and setts\user\dirToBeMonitored). So, I could be able to know which f...
What's the easiest way to play a sound file (.wav) in Python? By easiest I mean both most platform independent and requiring the least dependencies. pygame is certainly an option, but it seems overkill for just sound. ...
I have a problem writing a SQL statement for both Oracle and MS SQL server. I'd like to write the SQL so that it works in both. I don't want to have to mess around with setting a database type variable and switching I have a column of course names that have values like this: 9RA923.2008W 1223.200710 P0033330.200901 I w...
Yes, I realize this question was asked and answered, but I have specific questions about this that I feel were not clear on that thread and I'd prefer not to get lost in the shuffle on another thread as well. Previous threads said that rendering the email address to an image the way Facebook does is overkill and unprofessional user expe...
How do I know if I am overanalysing? I've been chasing a problem the last 3 days. I've been through many designs and reached a complex solution using about 3 classes. Having discussed with a colleague, I realized that all I need is one method and a struct. How can I avoid being an architecture astronaut? ...
Hi, A project is looming whereby some code that I will be writing may be deployed on any hardware that potential clients happen to have. Its a business application that will be running 24/7 so I envisage that most of the host machines will be server type boxes but smaller clients might, for example, just have a simple PC. A few more de...
I have made a custom dll for my setup project. My dll is very simple, registering few services, not CLR or any 3rd party lib dependent. Have statically linked with msi.lib only. I have removed the .net and windows installer prerequisite requirements from the setup project. My setup fails on macines not having .net framework..? As I hav...
how do cross platform frameworks like sdl or java provide platform independed keycodes. do they have mapping tables for all possible cases? or is there another (eventually better) way to achieve this. i need this because i am working on an open source framework for (continuous) dynamic keystroke authentication. i have clients int the fo...
I need to execute a program and retrieve its stdout output in c++. I'd like my code to be cross-platform too. Having recently discovered the wonderful world of the Boost c++ libraries for all your cross platform needs, I figured I'd just go to boost.org and read up on the documentation of Boost.Process. Much to my surprise, it wasn't th...
Hi, I'm looking for suggestions about choosing a portable way to achieve local IPC in a robust way, since i'm new to C++ and would like to avoid common pitfalls of fiddling with shared memory and locks; therefore I was thinking about message-passing style ipc. I was planning to use qt for other reasons anyway, thus i took a peek to Qt ...
I am trying to implement a simple, moderately efficient bignum library in C. I would like to store digits using the full register size of the system it's compiled on (presumably 32 or 64-bit ints). My understanding is that I can accomplish this using intptr_t. Is this correct? Is there a more semantically appropriate type, i.e. something...
I'm working on a paper about multi-platform programming and I'd like to include sections on advantages/disadvantages. From my understanding; having any application be multi-platform is a huge selling point for the developer since it enables almost any computer user as a potential buye, among other things. I'm just trying to figure out po...
I have build an installer using NSIS. And now I want to extend it to Solaris and Linux thorugh WINE. But I wanna know few things here- Is WINE flavour dependent? I mean are there different packages for different Linux versions? Whats if my Installer creates some SQL or Oracle database? Will this feature be also supported by WINE? Is th...
You always read in changelogs when your system or browser or any program updates that they fixed a bug that made possible that an attacker can execute any code in your computer with a forged website, or attacking your computer with carefully forged packets, etc... Because you read it so often that means any program can have similar vuln...
Hi, I'm working with an OCR project which is developed using Visual C++ on .net framework. But since the .net is platform dependent I want to make this project platform independent and make it supports to multiple operating systems. So can some one give me a hint to how to do it. Thanks. ...
Hello, I was searching a bit for another platform independent language like Java. Are there other P.I. languages? Thanks ...
I've already done some little things using Visual Basic and some nice things with eMbedded Visual Basic, but now I want to go on the scripting way, then I want to know if Linux, BeOS and other OSes browsers will support VBScript pages. ...
If one has three fields in a db that they are querying an object by.... One of these fields must always be an associations id. Concerning the other two fields "only one needs to be true" What interpretation do you take or make of "only one needs to be true"? ...
Is there a native PHP wbxml API that can be used platform-independently? Perhaps a loadable module? I have seen the pecl implementations but I have not been able to successfully work with the builds on win32 platforms. ...
The gnomonic projection maps spherical triangles to straight-edged plane triangles. But I've heard that the Chamberlin trimetric projection has less distortion, so I'd like to use that instead. Alas, when I use my (extremely rough and probably buggy) implementation of Chamberlin trimetric projection to map the spherical triangle formed ...
