However, since I’m only an amateur CS student without too many years of solid development experiences
(without the word solid, I may say 8 years, but with it, I’d go with only 5 years, being conservative),
I’m very hesitant to give myself a single 5 score on anything,
because I still need to occasionally check manuals and documentations on many technologies I work with.
For this reason, instead of numbers, I’ll show the scores with stars.
One ★ means one score (and it’s also more intuitive to look at).
Ordered at my own discretion, what I deem more important goes first :)
- C++ #3#
Stack Overflow activity (also my top tag as of May 2019)
Reason for not giving a fourth score: I’m not particularly familiar with STL and I haven’t participated in a scaled C++ project. This should be considered a downside as I’m familiar with C++ syntax and many sneaky language features (and that’s where my Stack Overflow score under the [c++] tag primarily comes from).
- C #4#
Stack Overflow activity (also my second top tag as of May 2019) and my repositories
- Python #4#
Stack Overflow activity
Also long-term contributor to SmokeDetector, a mid-scale Python chatbot that detects spam and deletes them rapidly.
- Bash #3#
Stack Overflow activity and a collection of my gadgets written in Bash or POSIX
- VBScript #3#
A vicious project and some gadgets.
- SQL #1#
Merely touched and played with. Built some projects with MariaDB. SQLite3 CLI utility is good for tampering game saves :)
- Ruby #1#
Barely touched Ruby, write short snippets to aid existing Ruby projects (my Jekyll website or other Rails apps)
- Verilog #1#
Learned from school courses Digital Circuit labs and Computer Organization and Design labs. Not practiced much
- Scala / Chisel #1#
Assigned a research on Chisel for performing particularly well in Digital Circuit labs, and have worked on a few entry-level projects (my COD repo and this RISC-V project).
- Flash ActionScript #2#
A very addictive plane-shooting game when I wrote back when I was 14. (Project home page)
The ugly “previous” website that I designed and wrote on my own. Also a few pages on this site contains short JS snippets serving for various purposes. jQuery included.
- Go #1#
Touched a little bit.
- Regular expressions #5#
The only item on this page that I dare claiming solid knowledge on. Still learned and practiced in the SmokeDetector project linked above.
- Git #3#
I was about to give myself a score of 5 on this when I realized that Ciro Santilli claimed the same score, but backed with a huge tutorial he wrote on his own.
Then I reevaluated myself and gave a score of only 3 - I can’t even write a fifth of Ciro’s tutorial.
- Linux #3#
Daily working environment (WSL) with enough supporting knowledge. Ironically, I don’t have a preferred desktop environment because I mostly work in CLI. I have a few Ubuntu and Debian servers that I maintain personally, including a Raspberry Pi.
What about checking out my tmux config?
- Windows Desktop #4#
Long since I was 12 I began to learn various configurations and tweaks (primarily the Registry) of Windows XP and Windows 7, which helped build my solid knowledge on Windows setup, maintenance and recovery.
Still using a Windows laptop (by MSI) for day-to-day working, yet heavily relies on WSL.
- Vim #3#
My most-used text editor. With Vim coding is just so easy and I’ve always wondered why one would need VSCode or JetBrains stuff.
- NGINX #2#
Preferred HTTP server over Apache. Have some experiences configuring and tuning it, as well as web optimization. Best paired with Docker.
- Docker #2#
My favorite application deployment solution, but haven’t got much experience with it. I also have private CIs running in Docker containers.
- LXD (Linux Containers) #2#
Did a project organizing LXD containers as VMs for students to do their course experiments on. Wrote a Django frontent with the help of
pylxd library. Also manages a small cluster of LXD containers for own and friends’ use.
- Make #1#
My preferred build automation system. Usually writes
Makefile for personal projects.
- DNS #4#
Have a deep understanding of how DNS works, and set up and maintained different kinds of DNS services (local recursive
dnsmasq / authoritative
bind9), and manages more than 8 domains and some servee clusters on my own.
- Hardware maintenance #3#
I assembled several desktop computers, and I maintain all my hardware on my own, ranging from my laptop to my phones. I send them to repair shops only when I identify that I can’t repair or replace it by myself.
- I disassembled new laptop even on day 1 of puechase, usually for an immediate upgrade (e.g. SSD 256 GB → 1 TB). (Dec 2018)
- I replaced a broken screen of an old phone manually. (Oct 2016)
- I dismantled a HDD to learn how it worked. (April 2016)
- I assembled my first desktop computer from parts. (May 2014)
- Cryptography #2#
My specialty in CTF competitions.
