I was trying to deploy a Rails application using Apache and got into some problems when I tried to configure the app so that Apache will be the one that serves the precompiled assets (javascripts, css, images and others). Since I’m on tight deadline (yeah, I should’ve tested production mode much more earlier), I tried my luck with Nginx and it worked easily without any hassle. So, this is how I did it.

Here’s a guide on how to setup Xen virtualization in Slackware.

This will be multi part post about high availability solution for Slackware. My first post will be about Corosync and Pacemaker.

You need to combine Corosync and Pacemaker with other distributed storage system such as DRBD/OCFS2/GFS. I’ll talk about these stacks in another post.

These are the steps I used to replace LILO with GRUB as the boot manager after upgrading my kernel to v3.

It’s time for an upgrade!

I’ve decided to merge posts about reading MyKad from my previous blog into a single post.

Notes:

1. The original codes were written by Xenon from Lowyat.net. Somehow, he managed to reverse engineer MyKad’s APDU so that we can read it without buying any SDK.

2. This application only reads data from Jabatan Pendaftaran Negara (JPN).

This should help you with NCReport in Qt.

This guide will help you (mostly will help me in the future) to configure your Ruby on Rails to support connection to Sybase.

I’m pretty sure I’m going to forget these steps, so, just to be safe, I’m putting it here. I’m dividing this tutorial into two sections, one for default MySQL that comes from Slackware and the other one is for new MySQL.

First of all, at the time of this writing, NVIDIA Hybrid SLI Technology is not supported on Linux and without proper configuration, you won’t even be able to load your Desktop Environment such as Xfce.

Known to work with:

• Slackware v13.37
• Qt SDK v1.1.5 (32 bit)
• Qt v4.8.0
• MySQL v5.5.18

The Story

At the end of last year, my friends and I were tasked to read our staff card. The main objective was pretty simple which is to create a library where we don’t have to depend on the vendor every time we want to read our own staff card and the library should also work in Linux and Windows (that means Java to us).

Apparently there’re some codes scattered on the net telling people that you can print to a Zebra printer by sending ZPL II codes using PrintService. But the problem is, it’s not working, I don’t know why, maybe because of a different version of printer or model but I’m pretty sure the thing that came out from the printer are just ordinary texts not barcode which is what the code was supposed to output.
