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.

I've been playing with Nuxt and some of its modules including the module one I like being to write everything in markdown and I have decided to move my blog from gridsome to nuxt just need to figure out pagination and how I can set up a feed to cross-post on here. I've learnt how to use async data with nuxt and how the config works.

I learn that angular has a validator to input checkbox to valid if it's true.

Eg: "aceptTerms":[false,Validators.requiredTrue]

Learnt that no matter how hard I pretend to have infinite capacity, I don't. Investing in getting everything to stop being overwhelming :)

@fasterthanlime Had an existential crisis, realized I said 'yes' to a few too many things and ended up making my life a mess, so I'm slowly going back and saying 'no more' and clawing back time and mental bandwidth. Could be far worse! Glad to hear you're having fun at work :)

I learned about JavaScript’s event bubbling and capturing which was so illuminating!

[Nick Taylor]

Noice!

Not programming related, I've been studying for my finals exams next week. Lots about DB management and OS design!

You can chain assignment operators in JS.

w = z = x = y 

This means you can also do horrible things like:

w +=y *= x -= z
