I learnt that multiple exclamation marks are allowed for visual representations of alarms on medical devices (IEC 60601-1-8, section 6.3.2.2.2), so I've added this to the css:

.alarmed::after
{
  content: "!!!";
}

My first use of ::after.

Here are my learning stuffs:

  • Using some hacking tools to practice some CTF challenges on hackable.ca and hackme.inndy.tw. It's hard work because there are many CTF challenges are waiting for me to resolve :).
  • I plan to build my hacking tool environment based on Ubuntu 18.04 to resolve above CTF website :).
  • Developing a web-based YouYube downloading site to let my family members download video on YouTube conveniently/easily.

You can chain assignment operators in JS.

w = z = x = y 

This means you can also do horrible things like:

w +=y *= x -= z
