I wanted something different:

• ⚡ Fast

• 🧼 Clean UI

• 🎯 Straight to the point

This tool is designed to help you quickly answer questions like:

• How much EPF will I contribute this month?

• What is my employer contributing?

• What’s the total deduction from my salary?

---

🧮 What the Calculator Does

The calculator lets you:

• Input your monthly salary

• Instantly see:

  • Employee EPF contribution

  • Employer EPF contribution

  • Total EPF contribution

It reflects standard EPF contribution structures used in Malaysia, making it practical for:

• Employees checking payslips

• HR or payroll quick checks

• Anyone planning savings projections

This isn’t meant to replace official tools — it’s meant to make your daily life easier.

Whether you’re:

• Checking your take-home salary

• Estimating job offers

• Planning monthly finances

This tool gives you quick, reliable answers without friction.

---

📌 Example Use Case

Let’s say you’re offered a salary of RM5,000.

Instead of manually calculating percentages or digging through EPF tables, you can:

1. Open the calculator

2. Enter 5000

3. Instantly see:

   • Your contribution

Integrate alert_threshold into Jenkins

To run this application periodically and ensure system admins/support receive timely alerts, a Jenkins installation is required.

1. Make sure you have already run this app as described in the How to run this app section.
2. Download and install Jenkins. While Jenkins setup is outside the scope of this document, more information can be found here.
3. Create a Freestyle Project in Jenkins and apply the appropriate settings. The minimum required settings are:
• Build periodically
• Execute Shell
4. That’s it! Check the console output for any errors. A YouTube video has also been created to briefly demonstrate this integration:

How to draw arrow in GIMP using plugin

GIMP is a great image editing program that allows us to alter images and better convey our intentions. I like using GIMP for tasks such as resizing, changing formats, or cropping images. In this article, I will explain how to draw an arrow in GIMP.

First, download the arrow.zip which contains two Scheme script files. There should be 3 files in total. Below is a summary of the files:

• ArrowScriptNotes.pdf : description of the arrow.
• arrow.scm            : Scheme script file for gimp version 2.x
• arrow_V3.scm         : Scheme script file for gimp version 3.x

Depending on your GIMP installation, copy the appropriate file to the GIMP script directory and then make it executable. For example , I'm using GIMP version 3.0.4-3 so I would do the following:

$ cp arrow_V3.scm $HOME/.config/GIMP/3.0/scripts

$ chmod 770 $HOME/.config/GIMP/3.0/scripts/arrow_V3.scm

$ # for GIMP version 2.x

$ # cp arrow_V3.scm $HOME/.config/GIMP/2.10/scripts

Restart GIMP if it is already running. I also created a YouTube video demonstrating how to draw an arrow using this plugin.

APC UPS 1200VA connected to linux debian

On 1st November 2023 was one of the worst ever day in my working life. One super strongest ever lightning strike completely shut off the the whole house electric supply! I have UPS connected to my laptop which the laptop also shut off abruptly. I would say "lucky" ? that that the laptop managed to boot up unfortunately the USBs are all broken, it does not function anymore. Never in my life would think that even with a laptop protected by an APC UPS, the device would be damage, well partially. Closer inspection show that laptop power adapter socket, the live connector got burned mark. It is just how strong was the lightning strike! So lesson learn, this time I bought a new APC UPS which connected in serial fashion and behind a surge protector (Targus) and hoping that with 2x protections, I will survive in the incoming lightning storm. hopefully. 🤞🙏

Let's see the APC UPS

and when it is connected and running

This unit come with monitoring system. It can be connected to the pc device via USB cable which is awesome! Best part is, if you are using linux, it comes detected automagically. At the time of this writing, I'm using Debian 12.7.

and even better, gnome automatically detect it. I was really impress how little effort require to make things work.

one thing it does not work out of the box is communication with UPS also lost... but not sure how gnome able to detect the battery percentage..anyway, guess this is the work require.

Now I know why zoom feature is available in operating system for.

I use to think why would an O/S feature is created as it sudden zoom ridiculous 10-100x of the current resolution. 

But as one age, it FINALLY make sense, all comes around! Let's give an example. Given the current view at current resolution of the following picture

Given the following webshot, what's the difference can you identify?

Sure, some with very good eye can spot but it would also take sometime to identify. But if you can zoom in, wouldn't that be nice?! In linux , try super + alt + 8, yes the 8 is not on the numpad. Now it should be clearly shown what is the difference.

The display might be too small, try open the image in a new window tab. It should be clearly seen that the vertical line is dashed whilst the horizontal line is dotted. Well that's the difference!

It is like the zoom feature allow one to inspect the DNA.. well, computer DNA.. :) 

how to setup mariadb galera cluster in docker container

 1. create network (one time)

   docker network create --subnet=172.18.0.0/16 mynet123

2. create image that can start service in container (one time)

   mkdir systemd

   cd systemd

   vim Dockerfile

   FROM almalinux

   ENV container docker

   RUN (cd /lib/systemd/system/sysinit.target.wants/; for i in ; do [ $i == systemd-tmpfiles-setup.service ] || rm -f $i; done);

   RUN rm -rf /lib/systemd/system/multi-user.target.wants/ \

   && rm -rf /etc/systemd/system/.wants/ \

   && rm -rf /lib/systemd/system/local-fs.target.wants/ \

   && rm -f /lib/systemd/system/sockets.target.wants/udev \

   && rm -f /lib/systemd/system/sockets.target.wants/initctl \

   && rm -rf /lib/systemd/system/basic.target.wants/ \

   && rm -f /lib/systemd/system/anaconda.target.wants/*

   VOLUME [ “/sys/fs/cgroup” ]

   CMD ["/usr/sbin/init"]

3. build image (one time)

   docker build -t almalinux-md .

4. start the container in the background

   docker run -v /tmp/node1/:/var/lib/mysql --detach --rm -it --privileged --net mynet123 --ip 172.18.0.11 --name node1  almalinux-md 

   docker run -v /tmp/node2/:/var/lib/mysql --detach --rm -it --privileged --net mynet123 --ip 172.18.0.12 --name node2  almalinux-md

   docker run -v /tmp/node3/:/var/lib/mysql --detach --rm -it --privileged --net mynet123 --ip 172.18.0.13 --name node3  almalinux-md  

5. attach it and so can install mariadb and gelera, etc

   docker exec -it node1 bash

   docker exec -it node2 bash

   docker exec -it node3 bash

6. install in all 3 nodes

   dnf install -y mariadb-server.x86_64  mariadb.x86_64 rsync python3-policycoreutils vim nc telnet epel-release.noarch mariadb-server-galera.x86_64

7. on first node

   systemctl start mariadb

   systemctl status mariadb

   [root@6c3d7f5bc394 /]# mysql -uroot

   MariaDB [(none)]> set password = password("password");

   quit;

   systemctl stop mariadb

      

8. from step 5. wsrep_node_address and wsrep_node_name update to its corresponding name   

   [root@cfeee129fe92 /]# cat /etc/my.cnf.d/galera.cnf

   [mysqld]

   binlog_format=ROW

   default-storage-engine=innodb

   innodb_autoinc_lock_mode=2

   bind-address=0.0.0.0

   # Galera Provider Configuration

   wsrep_on=ON

   wsrep_provider=/usr/lib64/galera/libgalera_smm.so

   # Galera Cluster Configuration

   wsrep_cluster_name="ot_mariadb_cluster"

   wsrep_cluster_address="gcomm://172.18.0.11,172.18.0.12,172.18.0.13"

   # Galera Synchronization Configuration

   wsrep_sst_method=rsync

   # Galera Node Configuration

   wsrep_node_address="172.18.0.13"

   wsrep_node_name="node3"

   [root@cfeee129fe92 /]# 

9.  on first node, start the cluster

    galera_new_cluster

   

10. check on the first node,

    mysql -u root -ppassword -e "SHOW STATUS LIKE 'wsrep_cluster_size'"   

   

11. bring up the remaining nodes one by one

    systemctl start mariadb

    mysql -u root -ppassword -e "SHOW STATUS LIKE 'wsrep_cluster_size'"   

12. ready to write/read

mysql -u root -ppassword -e 'CREATE DATABASE playground;

CREATE TABLE playground.equipment ( id INT NOT NULL AUTO_INCREMENT, type VARCHAR(50), quant INT, color VARCHAR(25), PRIMARY KEY(id));

INSERT INTO playground.equipment (type, quant, color) VALUES ("slide", 2, "blue");'

mysql -u root -ppassword -e 'SELECT * FROM playground.equipment;'
