Cawbird - Linux Twitter Client

Sun, 05 Sep 2021 22:24:38 +0800

Peace be upon you and hello everyone!

Have you heard Corebird before? It a twitter client for linux desktop user but the project (and others 3rd party twitter client) stopped when Twitter decide to remove “UserStream API”.

Twitter actually replace that API with new ones called “Accounts Activity API”, but the Corebird developer stated it too difficult to implement and he may not have much time for development anymore. So the project was discontinue since 2018 and honestly, Corebird are the best GUI twitter client for linux.

My FOSS contributions and rants on Feb-April 2021

Sun, 18 Apr 2021 15:18:00 +0800

My rants and contributions to FOSS in Feb - April 2021

Involve with Debian and joined Debian Med teams, thank you Andreas Tille.
I intend to help Steffen Möller to package python-scanpy by fixing blocker and I end up packaging it missing dependencies which are python-sinfo and python-stdlib-list . Many thanks to who teach me how to packaging and Nilesh Patra for sponsoring me. The work on scanpy still unfinished, there is still leftover to do. WIP.
At same time I also send another ITP for python-scanorama, it working but the unit test asking for another missing package called as annoy from spotify and fbcpa from facebook.
Both missing package I able to rebuild locally but I not sending ITP yet. I send a request to Debian Python Team to join them and place both of this package under it.
I still contribute to Fedora as QA and few stuff. Another point, recently (actually few month ago but nvm, just put here), Izhar aka Kagesenshi get highsugar and re-activate the local community (Fedora Malaysia) via discord. He also setup a new team called Fedora Data Engineering SIG
After a while using and involve (contribute) with Fedora for fews years, I sometimes get a feel that Fedora and Red Hat moving so fast on everything and feel it not community oriented it more like leader oriented, take a look on something worth called as “flamewar” on Fedora-devel list which debate on changes on os-release.. check the Wiki here

There is few’s more contribution but I not keep track it properly, will update when I remember it 🤪

Fedora - dnf history with fedora-repos-archive

Fri, 01 Jan 2021 05:52:00 +0000

Fedora use dnf as package manager and dnfhave option to see transaction history and undo/rollback the transaction.

For example I updated icecat web browser via dnf update icecat to newer version that just released and then after installed the newer package, I can check and see my last transaction history :

bash

$ dnf history info last
Transaction ID : 15

As we can see, I just updated my icecat web browser from 78.5.0-2.rh2.fc33 to 78.6.0-2.rh1.fc33 via dnf at 31 Dec 2020 09:31:29 AM.

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

How to disable ICMP ping replies (linux)

Tue, 08 Dec 2020 01:42:00 +0000

Few weeks ago during server setup phase for one of my project, I notice there is no ICMP or ping replies from server and some port are not able to access.

I told the network engineer to check and seem they blocking the ports and disabling ICMP replies from their firewall configuration.

From that accident I do some google-fu if I can do same thing for personal computer / server. We can setting the kernel variable or use iptable to disable ICMP / ping replies if requested.

Sending JSON data file using CURL to API endpoint

Mon, 30 Nov 2020 10:23:00 +0000

I developed warehouse system and use restful as communication method between our software and client software. We let end point of our system to talk each other with API designed.

For simple and small test using Postman or SOAP-UI is enough for me but to when to test this system with massive data via API is quite headache, plus the mock features on Postman limited and not “mocking” enough as I want.

Fedora rawhide + everything : bare-bones minimal KDE

Mon, 05 Oct 2020 01:12:00 +0000

The goal of this articles is how to get a bare-bones KDE desktop from Fedora rawhide everything installer. I’d welcome any suggestions and comments to improve it.

Let me remind before we proceed, Fedora rawhide is pre-release / testing / master / current development / rolling version of Fedora. Please read here for more details. If you are novice and not advance user, please don’t follow this tutorial, it not stable and “new unreport wild bugs” may appears and you will have problem to troubleshoot.

Setup python 3.6 enviroment with virtualenv

Tue, 23 Jul 2019 09:00:00 +0800

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! 😬
