This Week I Learned 2018 - Week 49

Last week post or some old posts.

How to identify and utilize the hidden pocket time available? Surprisingly, there are 13 time slots available. Generally, how do we to shed unnecessary time off your daily schedule, for examples, choosing what to wear or 40 minutes per day on buying stuff? Planning, automation, and limit the choices you've to make. Plan your week ahead, preps your meals up front, or wear the same type of clothing everyday. All these to prevent decision fatigue by removing yourself to make unnecessary decisions in your daily life.

What are you thankful for? I share the same sentiment with this person. Of course, personally, be content.

Does quitting social medias like Instagram or Facebook make you happier? (via HN) Indeed, as the author experienced, it will make your lighter and thus happier. I believe the same experience you felt when going for vegetarian food for a period, your stomach felt lighter. As usual, moderation is the key but take note, these apps were explicitly designed to "consume" you. Start slowly. Instead of drastic changes, disconnect yourself during the weekend, then weekday, and finally totally remove yourself from it.

How does one living with less? Fit everything you own into one carry-on bag. As usual, there always a subreddit, r/onebag, exists. If you travel a lot for a long period of time, the author list of items is a good way to start or reduce the "stuff" you owned to the essential bare minimum.

How smooth jazz took over the '90s? When you mix the technicality of Jazz and melodically of Pop music, then you have Smooth Jazz.

Is Microsoft Edge (Spartan render engine) or Internet Explorer (Trident render engine) going to be replaced by Microsoft own version of Chromium? Yes and finally bloody yes. (via HN) The demise of Edge/IE browser allows me to check off an item from my to-do item after so many, many years of painful experiences and wasted numerous hours trying to get web sites / web apps to work correctly with Edge/IE and numerous hacks and workarounds (remember the stupid box model and their refusal to fix it?). Maybe right now we can have a consistent and standardize web browser render engine with minimum differences. Yes, they may pull another "embrace, extend, and extinguish" strategy again but at least right now we have a FOSS web browser and Firefox.

Why you should switch to Firefox web browser? (via HN) If you values and concerns about privacy. First, Mozilla values your privacy. All the browser data (bookmark, browser history, and etc) synced through Mozilla Sync cannot access by any parties except you. Second, the Firefox Multi-Account Containers extension where cookies are not shared and kept within the container tab itself. This means that each tab is a new browser session and isolated from other tabs where you can use multiple identities and accounts simultaneously. For Google Chrome, there is this extension, SessionBox that did the same but do you trust a third party vendor instead of Mozilla? Third, tracking protection is already built into the browser itself.

This Week I Learned 2018 - Week 39

Last week post or some old stuff.


What is the worst pain you've ever experienced? For a woman, giving child labour. For a human, kidney stones. Contrary to the headline, (via HN), it's NOT beautiful at all but excruciating painful and can put a tough guy down to his knee.  Imagine coral reef passing your kidney or being stabbed in your kidney. If you're facing financial issue, maybe you should try roller coaster to get those stones out. Yes, it works and it's proven scientifically. What can you do right now? Prevention is still better than cure. Less salty food and drink plenty of water, like 2 litres per day.

How many books you should read at a time? Three. One hard, one easy, and one very easy. Currently I'm reading just one hard book (the material is so dry). The next step is to find another easy (fiction perhaps?) and very easy (manga?) book. Which time slot I should allocate to? Judging from my almost daily progress, is it possible to finish three books per month?

What is the most additive game in this year's JS13kGames competition? (via HN1024 Moves and I'm quite surprised and addicted to the games. The creativity shown in some of the submissions have reminded me how computing power have changed since the early days of computing.

How do we prevent muscle loss as we age? (via HN) Nothing but strength training. Every single fscking day. The MRI image below tells a lot about the importance of exercise towards maintaining your muscle flexibility regardless your age. The usual exercise regime should be 150 minutes and 3 times per week. Instead of cardio, maybe I should focus on strength training (weight lifting). Furthermore, building muscle actually burns more fat.

So Good They Can't Ignore You? (via HN) I can relate to the opposite view instead what of the book preaches. Is the book worth it? Yes, it's a popular-science writing made easy for layman. Once you've done with the book, you should explore something deeper like Flow: The Psychology of Optimal Experience. Read both book and the scientific papers published. Regardless your passions or skill sets, reality have to step in.

What is the dark side of working at a successful startup? Not surprisingly, money and lots of money. Money changed people. Sadly, towards the evil side of human nature. Some may argue this is reality of life. Perhaps.

Does four days work week possible? (via HN) Yes, either four-tens or you take a pay cut. Possible for those working in Asia region? Doubtful.

Which type of programmer you are? There are two types, starter and finisher.

Next.js? If you need a proper framework than the bare essential React. The frontend is so crowded and mess right now.

This Week I Learned 2018 - Week 27

Last week post or something from the archive.

How does we diagnostic aquarium tropical fish diseases? There are many ways and this diagnostic website (there is another one with better graphic) provides a quick way to identify the actual disease based on several symptoms. Aquarium Co-Op recommends three medications besides all quarantine any fishes into this aquarium store. MSR also used similar way. We're a bit concern on the usage of Erythromycin (which is an antibiotic) as it may cause antimicrobial resistance. Moreover, we're not sure about the side effect of long term exposure towards human to this medications. Unless you're managing a aquarium store, it's best to use natural ingredients (garlic or Indian Almond leaves) instead.

Buying new headphones? I've been asked this question numerous time for the past week. Just visit Audio Guide. One thing I've learned is that budget aside, you can pick the head phone based on different sound signatures such as V-shaped, bright, neutral, dark, warm, and mid-forward (names can be different). I was wondering how does this apply to Hi-Fi system? More posts on this in coming future regarding these audio signatures.

What sound track for testing your audio equipment? I recently rediscover Yosi Horikawa. His Vapor album is a good start. A mix of nature sounds, human voice, and music mixed together.

Can you suggest one way to improve your writing? Vary your sentence length. Gary Provost gave a good example in his book "100 ways to improve your writing" as shown below.

Monotonous 5-words sentence.
This sentence has five words. Here are five more words. Five-word sentences are fine. But several together become monotonous. Listen to what is happening. The writing is getting boring. The sound of it drones. It's like a stuck record. The ear demands some variety. 
Varying sentence length.
Now listen. I vary the sentence length, and I create music. Music. The writing sings. It has a pleasant rhythm, a lilt, a harmony. I use short sentences. And I use sentences of medium length. And sometimes when I am certain the reader is rested, I will engage him with a sentence of considerable length, a sentence that burns with energy and builds with all the impetus of a crescendo, the roll of the drums, the crash of the cymbals--sounds that say listen to this, it is important.
Picking up React? What the best way for seasonal developer to start? React from zero (via HN). Note that web components (custom HTML element) may seemed to overlap (some part of it) with React.

Is this capitalism? Regardless how much you earn, there should be a threshold amount where you will reach an equilibrium of having enough and not being a slave to your money.

How will the 2018/2019 NBA season looks like? This comic said it all (via 老崔愛叭噗). The weird thing was the NBA free agency was way more bizarre and shocking than the FIFA world cup. Talked to a few people and the general consensus was that FIFA this time was quite boring.

NASA and FBI, what the difference? The former is an abbreviation where you can pronounce it as a word. Meanwhile, the later is an initialism or alphabetism where you pronounce it as individual alphabet. 

This Week I Learned - 2017 Week 33

Last week post or the old ramblings.

The Vox POP is probably the most entertaining and educational YouTube channel right now. I wish they produce more and frequently.

Mommy, Why is There a Server in the House? Suitable for those who are active in /r/homelab.

Refurbished my battle station and upgraded my Fedora 25 to 26. Nothing special about this release and I was expecting something significant or may be I miss out something?
$ sudo dnf upgrade --refresh
$ sudo dnf install dnf-plugin-system-upgrade
$ sudo dnf system-upgrade download --releasever=26
$ sudo dnf system-upgrade reboot

Gigabyte MA10-ST0 powered by Intel® Atom C3958 SoC. A 16-core Atom (C3958 SoC) server board which can be a good server-based motherboard for virtualization or NAS. Think ESXi, FreeNAS, or Proxmox. I was thinking of buying and setting one up for data hoarding.

Does programmer needs office? Definitely. I still fail to understand why corporation still craze over open office floor plan. It's very hard to concentrate without any distraction. People walking by and talking non-stop. Collaboration doesn't means physical communication, it can be done through any messaging app. Private office does works. The funny thing is, I miss cubicle. At least you can really concentrate and work in the zone.

Unknown electronic parts? Get it from Octopart. Buying chips and checking availability? Find Chips.

Speaker broke down and I need to get a new pair of cheap bookshelf speaker. Initially was searching for a pair for good bookshelf speaker like Pioneer SP-BS22-LR, but unfortunately, this model have been either phased out or you have to purchase whole Hi-Fi set. Meanwhile, no local distributor is importing Micca PB42x. I read good review on Swan HiVi D1010-IV or Swan Hivi D1080-IV, might as well allocates budget to purchase this instead. Luckily we can still find it from the local supplier and the price still acceptable, within MYR 450-plus. All this discussion about cheap and good quality speaker is useless if you can't can't hear audio quality? Otherwise, you're just wasting money without any actual benefits.

When you have a pair of speakers, to get the best out of your 2.1 setup. The next purchases will a Digital Analog Conveter (DAC), which convert binary bits (zero or one) to analogue signal and a amp. If you have a DAC, you can skip buying a sound card. Popular DAC is Behringer UCA202 or UCA222 and for amp, Lepai 2020A+SMSL SA50Diagram below illustrates this setup.

Slow MySQL performance in Docker instance? Use TMPFS, where you put the whole database into the RAM. The approach for MySQL docker instance seems easy enough to setup and there have been many documented results.

Why are we trying hard to optimize the MySQL Docker instance? One of the main issue is that big database restoration may kill the MySQL daemon due to either large volume of records. Which begs the question, how many rows? This is determined by server parameter of `max_allowed_packet` or adjust the server according to these parameters.
- bulk_insert_buffer_size = 256M
- innodb_log_buffer_size = 64M
- innodb_log_file_size = 1G
- max_allowed_packet = 1G

While we're on MySQL, it seems we can delete records from two tables in one DELETE statement. The key thing here is the columns from both tables need to be specified.
DELETE a.*, b.*
FROM table1 a
LEFT JOIN table2 b
ON =

It has been a while that I talked about Perl. Getting unique array list. Sigh, every single damn time I've encountered this I was wondering why this is not built into the core language itself?

GNOME is 20 years. It has been so long since I first tried it. I'm getting old. After Ubuntu switching to GNOME as default desktop environment, I felt that GNOME have finally won the GNU/Linux desktop war against KDE after so many fricking years.

No space life in Docker Machine in Windows? Maybe you can recreate another `default` Docker Machine following these settings. Assumed you're using VirtualBox.
$ docker-machine create
--driver virtualbox
--virtualbox-memory 8096
--virtualbox-disk-size 40000
