Hi, I'm using delayed_job to run jobs, with new jobs being added every minute by a cronjob. Currently I have an issue where the rake jobs:work task, currently started with 'nohup rake jobs:work &' manually, is randomly exiting. While God seems to be a solution to some people, the extra memory overhead is rather annoying and I'd prefer...
I want to get the exact size of a particular dir in linux through a C program. I tried using statfs(path,struct statfs &) but it doesn't give exact size. I also tried with stat() but it returns size as 4096 for any dir ! Please suggest me the way through which I can get the exact size of dir just like we get after "du -sh dirPath" comma...
I need to get Python code, which relies on Python 2.6, running on a machine with only Python 2.3 (I have no root access). This is a typical scenario for virtualenv. The only problem is that I cannot convince it to copy all libraries to the new environment as well. virtualenv --no-site-packages my_py26 does not do what I need. The lib...
I dynamically load a library in C++ like described here. My abstract base class looks like this: #include <boost/ptr_container/ptr_list.hpp> class Base { public: virtual void get_list(boost::ptr_list<AnotherObject>& list) const = 0; }; And my library now provides a derived class Derived class Derived : public Base { ... }; void...
I have a dir with files and dirs in it. What I want is to make rsync copy of several folders from that dir. For example, lets say I have this: /home/user -- drwxr-xr-x folderA -- drwxr-xr-x folderB -- drwxr-xr-x folderC -- -rw-r--r-- file.1 -- -rw-r--r-- file.2 I want to copy folderA and folerB using rsync. I have created file rs...
Using Bash, how can you traverse folders within specified folder, find all files of specified file type, and every time you find a file, get full file path with file name and full file path without file name as a variables and pass them to another Bash script, execute it, and continue searching for the next file? ...
Hello all, Is there an option for the CURL command to show only a percentage output to shell rather than all of this, for example: % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 12.4M 100 12.4M 0 0 4489k 0 0...
How does one programmatically cause the OS to switch off, go away and stop doing anything at all so that a program may have complete control of a PC system? I'm interested in doing this from both an MS Windows and Linux environments. Any languages or APIs considered. I want the OS to stop preempting my program, stop its virtual memory...
This is what I have so far: [my1@graf home]$ curl -# -o f1.flv 'http://osr.com/f1.flv' | grep -o '*[0-9]*' ####################################################################### 100.0% I wish to use grep and only extract the percentage from that progress bar that CURL outputs. I think my regex is not correct and I am also not sure ...
I am a systems programmer, so i just know some basic css/html. I like to learn basic of template development for sites. I have some idea about joomla. wordpress, and I am also experimenting with few wikis. A friend of mine is fireworks/photoshop advanced user, it looks quite easy to make a template using fireworks. Is there any equivalen...
Hello all, I am about to be writing a Ruby on Rails app which will use sub-domains to authenticate users. We will have two types of accounts: user accounts domain accounts Users will thus be able to belong to multiple domain accounts using the same credentials. I hope to have the ability for a domain account administrator to be able...
Hello everyone, I'm tasked with choosing an open source web browser to run on a fairly low-end embedded Linux system, that is ARM based. I'd really appreciate some advice. I've been doing some research and there appear to be a few choices: Firefox/Mozilla - too huge to run on limited resources Konqueror/Embedded - the development appe...
We've been bashing our heads off of this one all morning. We've got some serial lines setup between an embedded linux device and an Ubuntu box. Our reads are getting screwed up because our code usually returns two (sometimes more, sometimes exactly one) message reads instead of one message read per actual message sent. Here is the code ...
Users will be remotely accessing ***nix based machines via SSH and I need to determine the fastest way to check if the username that they are currently using has NOPASSWD access in the /etc/sudoers file. Possible options: grep for the username in /etc/sudoers, parse command prompt output to determine if it has NOPASSWD, if not, remove...
When mail() fails, there not much info about what went wrong. I understand that the best course of action is to check your sendmail logs, or whatever mailer has PHP used. But from a programming and pragmatic, point of view: on a Linux hosted environment, what can a PHP program do to get as much extra info to properly log the failure, pro...
Ok, the setup is a bit convoluted. Don't blame me, I'm not the sysadmin. Here's the situation. There is one machine that I can SSH into from outside the network. I can only remote in as root (yes, you heard right) using my private key. I know that it is more typical to log in as a user and then elevate privileges, but in this case, I ha...
Im trying to use inotifywait to detect every time a file or folder gets moved into a folder in realtime (eg. /root in the case) I tried this, which does detect both folders and files, but this is for a created file, I want it for a moved file/folder. inotifywait --monitor --format %f --event create /root So then I use this, but using...
I'm interested in setting up my own website-based game (PBBG) as a hobby. Traffic shouldn't be too much, a couple of dozen users at a time on average. From all the reviews I've seen, Ruby on Rails is the best way to go as far as coding and platform. As far as OS goes, I've only used Ubuntu in the past and, while it worked smoothly, I ...
I want to check internal web pages, so I cannot use the W3C validation service directly. I managed to run the XHTML validator locally, however, I have some problems with the css-validator. I do not really want to setup Tomcat or Jigsaw in order to be able to run Java servlet, and the commandline option give me an error message Exception...
