IBMs acquisition of Red Hat

02 November 2018 | 3 min read

For those that haven’t been paying attention, IBM announced on Sunday (28-10-2018) that it will pay $34 billion to acquire Red Hat and the deal is on pace to close in the second half of 2019.

Many were shocked by the news as I see lot of discussion regrading this kind of thing on Fedora user mailing list, IRC channels, Reddit and etc.

Lot of people from Fedora and Centos communities are throwing all kind of comments, thoughts, reaction and response. Everyone are curious what happen next especially on RHEL, Fedora and Centos. Plus, Java developers also wondering what kinds of changes are coming to the Java ecosystem too.

BTW, I think Oracle has to hate this deal because Oracle’s Linux (the kernel part) is based on Red Hat.

The news are wildly spread on Fedora 30 released date and few days later, Red Hat 7.6 Beta are released. Are this is the last and final version of Fedora and RHEL released?

Sync clipboard between remote and host when using VNC on SLES

09 October 2018 | 2 min read

I need to run simulation tool (GUI application) on our EXSi testing server booted with SLES11 P4 (SUSE Linux Enterprise Server Patch 4).

So I created simple VNC server session by vncserver -geometry 1024x768 -depth 16 from ssh terminal.

VNC session created and by default it will load TWM desktop when you access the remote server with VNC. It very lightweight but too geeky and slugish for me. I prefer KDE or GNOME.

To load KDE, you need to modify ~/.vnc/xstartup file. Comment or remove twm & and replace with that line with /usr/bin/startkde. Then kill existing VNC session and start VNC session. For Gnome just change it with /usr/bin/gnome. Only one desktop type should be inside your configuration.


Sync clipboard between you and remote server (SLES/SUSE) on VNC

I need to transfer some string data with copy and paste between me and remote server that connected with VNC, but by default both client and host clipboard are not transferred and I don’t like it.

Fedora 28 - Linux, Apache, MariaDB & PHP

I need to setup a working LAMP environment on my Fedora 28 workstation. I created out this tutorial as my personal references and it might be useful for you.

First thing, you need to update your repository at first :

$ sudo dnf update --refresh

Then, lets begin to install Apache web server and MariaDB database server:

$ sudo dnf install httpd
$ sudo dnf install mariadb-server

Now install PHP engine and some dependency

$ sudo dnf install php php-mbstring php-pear php-mysqlnd php-common php-pdo php-xml

Do you need PhpMyAdmin? I always need that:

$ sudo dnf install phpmyadmin 
  • It will install bunch of packages needed to execute phpmyadmin.

Start Apache and MySQL services via systemctl:

$ sudo systemctl start httpd.service
$ sudo systemctl start mariadb.service

Linux Fedora 28 and Avantree ANC032 wireless headphone

10 September 2018 | 4 min read

I just bought a headphone from Shopee (use referal code RYUUN222 to register and get discount!) website. I planned to buy one since last year but keep pending and now it suitable time to grab what I want.

The original plan is to buy Sony WH-1000XM2. I still remember on Jan 2018, I come back from Hong Kong to Singapore (I arrived at Changi Airport). I want to paid Sony WH-1000XM2 from the store inside the airport but my CC is limit per day, so I need to cancel my purchase :’(

I looking some decent and more cheaper headphone. I looking an wireless over ear head phone with noise cancelling featured.

My personal laptop have built-in bluetooth adapter and audio jack port are broken.. so wireless is my solution.

Why I looking headphone with noise cancelling feature? Currently, I worked as software developer of warehouse conveyor system, so during comisioning I will be on-site and the noise from conveyor and other machine inside warehouse are very annoying and disturbing when you need to focus doing stuff.

Seem Avantree just released new product, a wireless headphone with noice canceling feature and the price is much cheaper than other brands.
