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 : BSL20180316 : HMPK Super Red (S) x HMPK Blue (S)

Size does matter! One of the difficulty in breeding Betta fish is the male size. If you have a small male Betta, it's very hard for the male to mate and breed with the female Betta. Generally, the female Betta will become more aggressive and attack the male Betta instead. This was the case here for this particular small male.

Male: HMPK Super Red
Age: 3+ months
Temperaments: Fast and very aggressive.
Size: Small (2.5cm body only)
Grade: B+

We were thinking maybe the small size because this male was still a juvenile. But after one month of observation and being well fed, the body size still remains the same. Hence, our conclusion this was a mature male Betta but with smaller body size.

Female: HMPK Blue
Age: 3+ months
Temperaments: Quiet and passive.
Size: Small (2.0cm body only)
Grade: C

The second smallest female Betta in our collection. Yet, we think it was a suitable choice for the small size male. While we can't see vertically stripe lines and any eggs from this female, we believe this female can mate with the male. Colour-wise, it's unimpressive with dark blue although the body shape was quite nice.

Log Notes
Let the blue female Betta into the breeding tank. The male was very playful with the female but not attacking it in any possible way. We thought history going to repeat itself again where both fishes will flare each other but will not mate.We leave it as it without any interference.

Since there was not eggs produced and the blue female Betta was inactive at the corner, we replaced the female with another super red female Betta. As usual, using the same water from the breeding tank, quarantined the blue Female for a few days before we relocated it back to the sorority community tank.

We're surprised to find out that fry were hatching and swim vertically this morning. We thought that the original pair failed to mate. The next step was to remove the other female Betta super red from the breeding tank immediately. The poor super red female Betta was bitten quite a few times and its fins was somehow damaged due to our oversight. Note to self, check the bubble nest properly with good light source. Maybe the bubble wrap was not a good choice for a base of bubble nest, it was hard to observe any eggs.
