Django logger (my personal favourite format)

Thu, 09 Mar 2023 22:28:51 +0800

Personally, I do lot of programming using JAVA and log4j is my favourite package that I use on my project.. but sometimes I also use PYTHON and been using DJANGO framework because of it simplicity and easier to deploy.

When I use DJANGO, I still prefer to have logger on each of importance line of code (LoC) so I can trace back what actually happened when the code are executed.

Fedora - koji kernel regression testing

Thu, 31 Dec 2020 08:45:00 +0000

I will show how to get latest kernel from Koji for testing purpose. For your infomation, Koji build packages take times to appear on updates-testing repository.

The faster way to get latest kernel the is manually download from Koji. As example here, on this blog post I will show how I will load kernel kernel-5.10.4-200 to my Fedora 33 Workstation.

Firstly check the latest success build kernel here

For example, I will use this build

After awhile, I found the solution, I actually just need to install qt5-qtx11extras-devel package from Fedora to allow cmake found the dependencies needed and everything is working fine now.

Where the heck is “Qt5Qml” ? I try my luck and I am right, the package from repository that I need to be install are qt5-qtdeclarative-devel

Use this - GrepWin [Windows]

Thu, 30 Jul 2020 16:01:57 +0800

If you are linux enthusiast users then you know how to “grep” and how useful this tools.

Sadly, there is no built - in tool on Windows that can beat “grep”. So I looking for third party software and found this tool called as “GrepWin”.

It licensed under “GPL-3.0 License”. Oh, please take note it only can be use if you are using Windows 7 SP1 and above, It won’t work on Windows XP or Vista!

Use this - My favorite tools

Thu, 30 Jul 2020 15:54:23 +0800

Assalamualaikum and hello everyone,

I plan to create some blog post section called Use This. Yeah, I gonna post about what software, tools, script that I use. It just my own personal preferences of choices and I just recommend what I am use.

Maybe this kind of blog post will be useful and I also can jot down my settings and tweaks for everyone and my future references.

It will be cross platform, so Windows and Linux will be listed together. No worries. I will covers opensource, free and commercial software. Each post will hold only just one tools. Not just like regular “use this” interview that put all they favourite into one posts.

Komuniti “Mambang.org” atau “Mambang.org.my” atau lebih mudah disebut “Mambang” adalah sebuah komuniti opensource tempatan yang sangat berahsia binti misteri tapi mempunyai banyak khazanah dan produk yang bagus.

Setup python 3.6 enviroment with virtualenv

My wife ask me to convert few of PDF files to Excell spreadsheet. I did same thing last year by creating some small scripting program in python to do the conversion, but I don’t know where I put my code right now. Maybe lost during formating my laptop last year..haha 😜

I am 懒 right now (guess what I wrote in hànzì) and I don’t remember how I did last time. Hahaha.. With my Google-fu skill, I found out DfTables offer free API for converting document to another format. Nice! 😬
