I have spent countless hours playing role-playing video games. Recently, I bought Icewind Dale: Enhanced Edition for Linux. It is still a great experience, but I have to admit that I have gone to the dark side and modified the save file. Just think of it as a programming exercise.
I wrote a simple application to explain the current
UMASK value. It was a while ago, but I want to share it with you as it is quite a useful utility.
Sometimes I want to monitor and log particular PostgreSQL statements or execute other kinds of external action.
I am using the notify mechanism and slightly modified sample application found in the database documentation to achieve this.
Today I have found an interesting issue as I tried to forbid shell script execution from different directory.
After a longer period of time, I have decided to install Kolab and use it as a personal information manager. The installation process went as expected until the setup process tried to install the Roundcube database and failed miserably.
Learning programming may seem like an impossible feat, that being said however, with the right resources and information just about anyone can learn the most essential language that is used today.
A couple of days ago, I mentioned calculating the sunrise and sunset times. This is an interesting problem, so after reading Astronomy Answers – Position of the Sun, I quickly implemented it using C language. It is only an experiment, so results are approximate.
As a small experiment, I wrote an elementary C program to display min and max values of the basic object types.
Last year I published the blog post Cacti – How to graph CCQ on Ubiquiti devices. Recently I updated ubiquiti_ccq.pl script, so it will work with all NanoBridge and PowerBridge devices.
As you probably already know, the CCQ value is not available via SNMP (AirOS 5.5.2), but of course it doesn’t mean it can’t be graphed using Cacti. To graph CCQ on Ubiquiti devices, you just need to use a simple script to read the desired value using the web interface.
