I run a particular program on linux which sometimes crashes. If you open it quickly after that, it listens on socket 49201 instead of 49200 as it did the first time. netstat reveals that 49200 is in a TIME_WAIT state. Is there a program you can run to immediately force that socket move out of the TIME_WAIT state? ...
At work we have an application to play 2K (2048*1556px) OpenEXR film sequences. It works well.. apart from when sequences that are over 3GB (quite common), then it has to unload old frames from memory, despite the fact all machines have 8-16GB of memory (which is addressable via the linux BIGMEM stuff). The frames have to he cached into...
I want to open a folder window, in the appropriate file manager, from within a cross-platform (windows/mac/linux) Python application. On OSX, I can open a window in the finder with os.system('open "%s"' % foldername) and on Windows with os.startfile(foldername) What about unix/linux? Is there a standard way to do this or do I have...
There are numerous libraries providing Linq capabilities to C# code interacting with a MySql database. Which one of them is the most stable and usable on Mono? Background (mostly irrelevant): I have a simple C# (.Net 2.0) program updating values in a MySql database. It is executed nightly via a cron job and runs on a Pentium 3 450Mhz, L...
I want to build a decently performing, but above all stable Linux system for home server use, on a reasonable budget. Sadly, I have several bad experiences trying to install Linux on recently purchased hardware. Whilst pretty much every component runs on Windows, Linux support is sometimes flaky or just plain nonexistent. Which off-the...
I know that default cron's behavior is to send normal and error output to cron's owner local email box. Is there other ways to get theses results (for example to send it by email to a bunch of people, to store them somewhere, and so on) ? ...
I have 1 process that receives incoming connection from port 1000 in 1 linux server. However, 1 process is not fast enough to handle all the incoming request. I want to run multiple processes in the server but with 1 end-point. In this way, the client will only see 1 end-point/process not multiple. I have checked LVS and other Load Bal...
On Fedora Core 7, I'm writing some code that relies on ARG_MAX. However, even if I #include <limits.h>, the constant is still not defined. My investigations show that it's present in <sys/linux/limits.h>, but this is supposed to be portable across Win32/Mac/Linux, so directly including it isn't an option. What's going on here? ...
I am writing a c program in linux. Commands like execv() require a path in the form of a c string. Is there a command that will return the current path in the form of a c style string? ...
I'm trying to install GODI on linux (Ubuntu). It's a library management tool for the ocaml language. I've actually installed this before --twice, but awhile ago-- with no issues --that I can remember-- but this time I just can't figure out what I'm missing. $ ./bootstrap --prefix /home/nlucaroni/godi $ ./bootstrap_stage2 .: 1: godi_conf...
I have a fairly standards compliant XHTML+CSS site that looks great on all browsers on PC and Mac. The other day I saw it on FF3 on Linux and the letter spacing was slightly larger, throwing everything out of whack and causing unwanted wrapping and clipping of text. The CSS in question has font-size: 11px; font-family: Arial, Helvetica,...
I've heard that creating a new process on a Windows box is more expensive than on Linux. Is this true? Can somebody explain the technical reasons for why it's more expensive and provide any historical reasons for the design decisions behind those reasons? ...
More out of interest than anything else, but can you compile a DirectX app under linux? Obviously there's no official SDK, but I was thinking it might be possible with wine. Presumably wine has an implementation of the DirectX interface in order to run games? Is it possible to link against that? (edit: This is called winelib) Failing ...
I'm using an Ubuntu 8.04 (x86_64) machine to connect to my employer's Cisco VPN. (The client didn't compile out of the box, but I found patches to update the client to compile on kernels released in the last two years.) This all works great, until my DHCP client decides to renew its lease and updates /etc/resolv.conf, replacing the VPN-s...
Simply, are there any Java Developer specific Linux distros? ...
I really enjoy Chrome, and the sheer exercise of helping a port would boost my knowledge-base. Where do I start? What are the fundamental similarities and differences between the code which will operated under Windows and Linux? What skills and software do I need? Note: The official website is Visual Studio oriented! Netbeans or E...
I know php scripts don't actually compile until they are run. However say I want to create a small simple program and compile it to a binary without requiring the php binary. How could I do this? I'v seen a few IDE's out there that would do this, but either they are all for windows or the linux versions don't actually build properly. Wh...
I normally boot into Linux using grub so have linux as the first hard drive in my machine. I have Windows installed onto a second hard drive and am trying to get grub to boot it. The grub config file contains title Windows rootnoverify (hd1,1) chainloader +1 makeactive but it does not work. ...
Following this question: Good crash reporting library in c# Is there any library like CrashRpt.dll that does the same on Linux? That is, generate a failure report including a core dump and any necessary environment and notify the developer about it? Edit: This seems to be a duplicate of this question ...
