This Week I Learned 2018 - Week 11

Last week post or something from the past.

Another week, another compilation of vocabulary list. The list of words were a bit tricky to cohere (一致,连贯) together into a convincing paragraph. Just let your imagination go wild then!
The island have been inhabited (居住在) by the isolated indigenous (土著) peoples since long before it was discovered by foreign outsider. Strangely enough, the tribe was hospitable (好客的) and willing to embrace outsider even though there was some resistant initially. People in the island are not herbivore (草食动物) due to the climate and available food source. Within the cold climate with little greens available, tuna fish is their daily source of protein. Tuna fish, due to its distinct smelly fishy odor inhere (存在) can lead to to halitosis (口臭), which can be quite put off to outsider. The people in the island adhere (持有信仰) to a strange religious ritual where they don't inhume (埋葬) the death but instead leave it open in the wild wrapped in Tuna fish skin in a helical (螺旋) way. Everyone was inhibited (抑制) from getting near to the burial ground forever as it will bring bad luck for those who ignore the rule.
Ask HN: Were we more productive 10, 15, or 20 years ago? The question raised was related to development works itself. Were we? When comes to web development, not really, more marketing hype and too many choices available. Furthermore, too many tools, and too many abstractions. In other words, paralysis by analysis or decision fatigue, which made us ends up doing nothing.  What worse, we were bombarded by so-called news these days which read like tabloid instead. Technology made things done faster but at a price, we're more disconnected and distracted. Or maybe we (those reaching middle age) are more grumpier.

The Pilot System rule. The first system will always developed incorrectly somehow due to lacking of understanding and edge cases. Focus on the programmer productivity instead of focusing on optimizing the system itself.

Lesson learned when breeding Betta fish. We've made a few mistakes by our self and pretty much can relate to the breeder himself.

While we're talking about fish, the best video so far on using salt in your aquarium or towards your fish. We must be using salt wrongly, no salts are created equally, even chemical components are different!

Betta Spawn Log : BSL20180315 : Giant Dark Blue (M) x Giant Galaxy (S)

After numerous attempts to mate two giant Bettas, we've finally found success with this particular pair. Compare to other types of Bettas, the giant Betta was probably the hardest to breed. First, it's hard to find good enough quality with reasonable price giant Betta (this is so true for female Betta). Second, giant Betta needs large tanks for growth compare to normal Betta, thus breeding this type of Betta without enough large tanks or plastic bottle is not recommended. Third, they have big appetite and thus additional costs in fish food. The nice thing about giant Betta is that they grow very fast and definitely a good choice for those who have big aquarium tank.

Male: Giant Dark Blue
Age: 4+ months
Temperaments: Aggressive but clumsy as well.
Size: Medium (4.0cm body only)
Grade: B

This male Betta was not our first choice but we failed to breed the female Betta below with other male Betta. And this male Betta seemed very compatible with the female Betta without trying to kill each other.

Female: Giant Galaxy
Age: 3+ months
Temperaments: Fast.
Size: Medium (3.0cm body only)
Grade: B+

Overall we love this female Betta, the body size is nice and balance. It was a lucky purchase from local breeder who were willing to let go a few female giant Bettas at an acceptable price. One unique characteristic about this Betta is this is one hell of fast swimmer. We've tried to mate her with three different male Betta and all of these males were unable to catch up with this female Betta. Only on one unlucky incident, its tail fin was bitten off by an very aggressive Giant male.

Log Notes
Both male and female Bettas were overly nice with each other and we thought both going to mate soon. Little we realized that both already mated and numerous eggs have been fertilized. The spawn seemed good enough. We decided to keep the female for a while as it's still mingling with the male Betta (suspect maybe to continue mating). Even the eggs were larger that normal Betta eggs (see photo below).
