The situation: I want to play around with IRC bots as general communications interfaces to other code I am investigating. The server hardware would be old and low-memory, but running on a relatively up-to-date Debian GNU/Linux install. I don't expect more than a hundred users at a time, tops, and probably in the single-digits most of ...
I'm wondering if mono.net is included in the default installation of Ubuntu, Kubuntu, and Fedora, and other popular distros? If so, does anyone have a good reason why NOT to use it to develop a new GUI application targeted mainly for linux? ...
When I'm in Windows, I use the excellent MicroOLAP Database Designer for PostgreSQL, but its not open source or multiplataform. Do you know or can recommend me an alternative to this software, that I can use in Linux? EDIT: Just to clarify, I don't want to use wine to emulate MicroOlap for PostgreSQL, it doesn't work too well, I would p...
What would be the best approach to install a keyboard hook on Linux (X-windows) in order to trigger some application when some key-combo is pressed?? Is there a way to do this regardless of which window manager is running? The idea is to have an application being called ( or brought to foreground ) when some key is pressed in a way simil...
I have Apache running on a public-facing Debian server, and am a bit worried about the security of the installation. This is a machine that hosts several free-time hobby projects, so none of us who use the machine really have the time to constantly watch for upstream patches, stay aware of security issues, etc. But I would like to keep t...

We have a large codebase that takes approx 12 minutes on the developer machines to auto-generate some Java 5 classes using JavaCC and then compiles all the classes as well as running the units test. The project consists of multiple projects which can be built in groups, but we are aiming for a full a build in under 10 minutes What tips...
I've been reading up on Linux's "swappiness" tuneable, which controls how aggressive the kernel is about swapping applications' memory to disk when they're not being used. If you Google the term, you get a lot of pages like this discussing the pros and cons. In a nutshell, the argument goes like this: If your swappiness is too low, i...
My custom homebrew photography processing software, running on 64 bit Linux/GNU, writes out PNG and TIFF files. These are to be sent to a quality printing shop to be made into fine art. Working with interior designers - it's important to get the colors just right! The print shops usually have no trouble with TIFF and PNGs made fr...
Hi, This is not a programming question per se, but this is certainly about something which would help increasing my programming productivity. In KDE, one can assign short-cuts to particular windows. This eliminates alt-tabbing completely and, is very very convenient when multiple apps(browser, console, emacs etc) are open. My question ...
Are there any good configuration file reading libraries for C\C++ that can be used for applications written on the linux platform. I would like to have a simple configuration file for my application. At best i would like to steer clear of XML files that might potentially confuse users. ...
Some people want to move code from user space to kernel space in Linux for some reason. A lot of times the reason seems to be that the code should have particularly high priority or simply "kernel space is faster". This seems strange to me. When should I consider writing a kernel module? Are there a set of criterias? How can I motivate...
I have backups of files archived in optical media (CDs and DVDs). These all have par2 recovery files, stored on separate media. Even in cases where there are no par2 files, minor errors when reading on one optical drive can be read fine on another drive. The thing is, when reading faulty media, the read time is very, very long, because ...

Is there a way set flags on a per-file basis with automake? In particular, if I have a c++ project and want to compile with -WAll all the files except one for which I want to disable a particular warning, what could I do?
