This Week I Learned 2018 - Week 06

Last week post or you're bored, something from the past.

What a long discussion on Perl 5 vs Perl 6.

唐山大地震。的确是一套催泪的戏。值得一看。另外一提,有人说要养鱼先要学会养水,直接说道养鱼的精粹!

Review of my total steps walked until now. Interestingly, on average is roughly around 5000 steps. Something far lower than the first target of 6000 steps. Need to make adjustment and reevaluate again. Also, good to get the replacement pedometer.



Follow up with last week video on our popular health drink here. In other words, check the ingredient of any processed food.


Discussion with a local Betta breeder confirmed our suspicion that in a spawn of frys, only 10% or less (1% according to Sturgeon's Law since 99% of everything are crap) are show grade (if both the male or female are show grade quality), the remaining are either grade A, B, or C. Nothing surprising here, the spawn is just following the nature law of normalization distribution.

One of the key issue (headache) in breeding Betta or any types of fish, find good food source with rich protein. Having a consistent food source for the frys will influence the speedy growth of the frys or even their survival rate. However, culturing food sources is a time consuming (smelly too) process.

If you want to breed Betta of certain colour, you've to selectively breed (it can be inbreeding or outbreeding) to achieve that. Interesting colour of Betta described below. We have one which was originally dark blue and suddenly he shed all his colour and become red. The type of the food source, water parameters, and stress level will also influence the outcome of the colour.
The actual colors of a Betta are layered. In order to produce a Betta of specific color, other colors that are layered on top must first be "stripped away" through selective breeding. The top color is blue; next is red, then black and finally yellow.
Straturday! I'm surprised how fun guitar duet was. Interesting indeed.


I know is bad but I'm trying to contain my laughter so much. But joke aside, it has been a brutal strech for him. He needs to go to a good team that fully utilize and appreciate him.
