Old but gold.

This science fiction / comedy / absurdist / completely serious talk traces the history of JavaScript, and programming in general, from 1995 until 2035. It’s not pro- or anti-JavaScript; the language’s flaws are discussed frankly, but its ultimate impact on the industry is tremendously positive.

Advice to new managers:

• Earn trust by giving it
• Inspire, don’t tell
• Eat lunch with your team
• Show their work matters
• Be a player-coach
• Feedback in private, praise in public
• In victory, lead from back
• In crisis, lead from front
• Be the manager you wish you had

I downloaded the beta and gave it a try.

At this stage, it’s already a better email client than Airmail.

Some notes:

• Amazing startup speed. Why can’t all apps be like this?
• Nice and clean UI. Community themes could be a great feature to have but I don’t mind not having it.
• I specially like the conversation list view. It’s just so clean.

TIL

series

async function series() {
  await wait(500); // Wait 500ms…
  await wait(500); // …then wait another 500ms.
  return "done!";
}

parallel

async function parallel() {
  const wait1 = wait(500); // Start a 500ms timer asynchronously…
  const wait2 = wait(500); // …meaning this timer happens in parallel.
  await wait1; // Wait 500ms for the first timer…
  await wait2; // …by which time this timer has already finished.
  return "done!";
}

Best year at work yet!

• I worked on a project (with a several members of my team) to migrate our apps onto Kubernetes cluster since the beginning of 2017. We’ve been using Kubernetes in production since.
• Convince and guide other teams to follow our initiative to migrate to Kubernetes.
• 💸 Significantly reduce our AWS bills with the use of spot instances / spot fleet while maintaining high availability of the system.
• ✌️ Got a new job!! Employer gave a counter offer matching compensation but I decided it’s time to move on.

Overall, I’ve set a concrete infrastructure for my company to move forward. I believe my team can step up and continue working on current projects.

My one and only

Being a dad is overwhelming but certainly a great experience. Sleep depreviation surely sucks but any bad feelings seems to disappear when those little tiny hands hold my face and give me quick kiss on the cheek.

More books

I will not force myself to finish the book I’m not enjoying or learning from. I did this rigorously last year just for the sake of finishing the books.

I also want to learn speed-read this year.

Average readers read at speeds of around 250 words per minute with a typical comprehension of 60%. Imagine if you can read at 500 wpm, you can read twice as many books. It’s truly an amazing skill to have.

Talks

I didn’t give any talks last year. I would love to do 1 or 2 this year. Let’s make it happen.

2018 is gonna be a great year!

From 2016. Still very good talk by Jessie Frazelle.

In the past, I used to use Ctrl+R to search my terminal command history but it’s unreliable. I couldn’t wrap my head around how it search sometimes.

Thanksfully, I was introduced to fzf and it’s has been a wonderful little gem. The power of fzf is much more than just searching through command history, depends on how creative you are.

The one I show here is just an example of how powerful fzf is. Basically, it can be pipe to just anything and fuzzy search that.

fh () {
    print -z $( ([ -n "$ZSH_NAME" ] && fc -l 1 || history) | fzf +s --tac | sed 's/ *[0-9]* *//')
}

Now go brew install fzf, add the above function and thanks me later 😁

A lot has changed since last I look at it. Still a bit awkward but the toolings around Lambda have significantly improved.

Found this on HackerNews. Very much on point, though I don’t quite agree with the last item.

1. You have to have your people’s back, this is the most important thing… be there for them, insulate them from problems and management stupidity and always fight for them.

2. Lead by example, never ask them to do something you won’t do yourself.

3. Communicate, I have booked on afternoon a week from 14:00pm till 16:00 and more to just talk with my team and discuss everything from work, to weather, sports, to bitch and moan against the company, etc…

4. Get together as much as you can on a real “team building exercise” - the whole team in another city for at least 2 days with a great party and lots of eating and drinking on company dime…
