This Week I Learned - 2017 Week 07

Last week post or the whole series.

When come to getting new stuff, I really should have a one-item policy. For example, if I'm going to get a new bag, either I sell off the existing bag or donate it out. Otherwise, no point having two bags where you only going to use one. Not only is wasteful, it's also a hassle to store it and clean it as well. Something for me ponder upon when I'm thinking of getting any new stuff.

#1 Six modern keys to wealth. HN user, monodeldiablo describes six possible ways for anyone to accumulate wealth. In essence, you should be competent (both book smart and street smart), persistent (perseverance), and extraordinary lucky (right place, right time, and right people).

Developers are generally book smart but always having difficulties to monetize their projects or technical ability (turn it into a business). The most recent example is JWE, the author and maintainer for GNU Octave is looking for job after 25 years of maintaining the software (I think he is doing a great job since he have been doing it for 25 years but having some financial difficulties these few years). I've made a small contribution to him and being a FSF associate member can help too (just make a note in your monthly contribution). Expect some blog posts on GNU Octave in coming future.

#2 Coroutines in Perl? Use Coro module. More on asynchronous programming in Perl in coming posts. Busy week and I can't seem to allocate any time to look into this. So many things to follow up and so little time.

#3 Prioritize! Prioritize! This reminds me of Stephen Covey's four quadrants approach (similar to The Eisenhower Method) of prioritizing to-do list and time management.

#4 theXeffect subreddit. Fundamental approach to build habits and prevent procrastination. Also known as the "Seinfeld Strategy". Following Bombjoke advice, the steps as follow.
  • Buy a pack of index card. Get the one from Daiso with 5mm grid.
  • Start with Bol√©ro by Maurice Ravel as your background music.
  • Pick a daily habit you want to develop. May I recommend meditation?
  • Write the reasons on why you want to develop the habit on the back of the card.
  • Start now. Do the habit. Once done, mark a big 'X' on the box. If you fail, mark a big 'O'.
  • Continue for 66 days or 2 months. A habit is formed after that period.
The index card by hardcase00 shown below is a good example to illustrate the steps mentioned. Look closely at the card. In order to continue the streak, he have different minimum meditation time ranging from 5 seconds till 15 minutes. Set your goal so low and easy that you don't have any excuses of not doing it. Remember the main purpose is not to focus on how long you can meditate but to develop a habit of daily meditation.



#5 Software developers who started after 35. I have mixed feeling about this. Is good that anyone who are diligent enough can pick up software development skill but Peter Norvig's post on teaching yourself programming in ten years reminded me otherwise. Well, it depends on how you see software development itself. Is it a tool for your to achieve your goal? Or a skill you wish to gain and master? Different people have different motivations.

#6 Is PostgreSQL good enough? (via HN) By far, best written technical post I've read this year. Sad about the font size though. Seriously, who read at such small font size? I've seen quite a few systems which can benefit greatly if they switch to PostgreSQL instead of MySQL. MySQL, being popular and easy to learn doesn't means that it's suitable for all scenarios.There are other requirements where PostgreSQL fits, for example, PostGIS. For a comparison between two to programming languages, MySQL is like dynamic-typed programming language and PostgreSQL is like static-typed programming language. If I'm going to develop any intranet web application which involves critical financial information, my first choice is definitely PostgreSQL.

#7 Goals are for Losers. Passion is Overrated. Provocative opinion but make sense. You need to implement a system or habit to achieve what you want in life. Not passions or goals. Example from the slide is losing 10kg is a goal but eating the right way is a system. To increase the success of what you want in life, use a system approach to acquire more skills which can increase your odd. Summary of this approach. Item #4 is also another good example of systematic approach increasing the success rate of what you want to achieve in life.
