This Week I Learned 2018 - Week 03

Last week stuff and all the archive posts.

大水冲了龙王庙 (一家人不认一家人)。看了几套大陆片,一直听到这句歇後語(英文应该是Idiom吧?)非常适合那些说话不直截了当,话中有话的人。另外还有几句普遍的,例如:
  • 有事鍾無艷,無事夏迎春
  • 豬八戒照鏡子(裏外不是人)
  • 秀才遇到兵(有理說不清)
  • 無事獻殷勤 (非奸即盜)
  • 泥菩薩過江(自身難保)
  • 快刀斬亂麻 (乾淨俐落)

Chinese New Year is around the corner, surprisingly this year, the weather is getting colder and not warmer especially after the Dongzhi festival. Several fishes have died due to infection and we suspected that tank contamination from other fishes without quarantine and cold weather may be the root cause. Water parameters are a dead and life issue for these fishes.

All the Bettas have been quarantines and water changes done on almost daily basis. Some of them are recovering and seems more active. We have change our approach to water changes and sea salt, which are good practices to keep the fishes healthy. Unless necessary, no more chemical like Malachine Green (debatable toxicity issue, it can kill both bacteria or fishes). Methylene Blue or Formaldehyde (aka Formalin) are still safe to use. Even so, each antimicrobials have their own safety issue and met with apprehension issue in the fishing industry, especially aquaculture (fishes breed for eating). Aquarium medication is an interesting area for investigating. Expect more future discussions on this.

Overfed your fishes? Expect bloating and constipation issue to follow suit. Nothing but pea to help them with their digestion. Surprisingly these fishes crave pea. Well, pea should be on their weekly diet then.

cron.weekly is no more. It's not easy to continuously writing up and weekly aggregate posts. Definitely you're going to burn out somehow or another. I've tried different approach and the only possible way is to do it on daily basis, sit down in front of you computer for 15 minutes and write something up. Consistency is the key here, whether you like it or not.

Cal Newport have a good write-up on digital de-cluttering. Find and cultivate high-quality leisure instead of instant gratification low-quality digital distractions (news feeds, social media posts, or videos). A deliberated and strategic pause of using your mobile devices will have quite a significant effect on your daily life. What are your analog activities? These is something I need to reflect upon. For a start, rediscover what you like to do when you're young? Long forgotten hobbies? That's a good start!

Yes, I've installing and setting up my printer and scanner drivers the wrong way (using the official M2070W drivers from Samsung) for so long. There always this conflict between the printer and scanner driver everything I've upgraded my Ubuntu distro. It took me a while, but I was made aware there have been this The Samsung Unified Linux Driver Repository since 2015. Adding a repository, update, and install the necessary drivers and everything works as intended.

Timezone cheatsheet in MySQL. Timezone is always tricky and to do it correctly or explain it persuasively to layman.

This Week I Learned 2018 - Week 02

Last week post or something recent from the past.

农历新年即将来临,在寻找适当的春联Antithetical couplet)时,偶然读到古代的「烟锁池塘柳」这上联,自古以来,难有适当的下联。但花燃山色用程序来寻找最佳的下联即搞笑又聪明。佩服!佩服!话说回来,历代比较好的对句如下:

  • 烟锁池塘柳,灯镶酒坊楼。
  • 烟锁池塘柳,炮镇海城楼。
  • 烟锁池塘柳,桃燃锦江堤。

After watching the demo on how to build your Javascript project using Webpack and Gulp. I'm seriously wonder what the eff have happened to the web development, especially the front end? While I'm for using latest development tools if possible, but the complexity of building and bundle the JavaScript rubs me the wrong way. Yes I know, once you get used to it and embrace it somehow. Where was the simple way of building web application?

When you're getting a new fish or plant to your tank, you will need to quarantine both. The issue with introducing new fishes or plants is that they may carry disease, fungus, and bacteria. Having a proper quarantine procedures also prevent potential pests (e.g. snails, insects, or worms) from being introduced to your tank. How we going to do that then? A teaspoon of aquarium salt and Methylene blue (a drop per gallon, depends). Vinita Phord have written a good introductory guide on the whole process. Adapt and adjust on your own.

Interesting talk given by a fellow data scientist who was originally a developer. Wish more young fresh graduates could join the talk. On the career side, the presenter gave tips on how to get yourself ready in data science. Three things: build enough competency, have confidence, and know enough to get it through. Always hire for the right reason, not just mere head counts. For young people, the most important criteria for selecting a job is the role is supportive to your career growth. Not just the salary, when you're fresh, pick the right environment to learn and contribute. Unfortunately, the talk was diverted into another old unresolved discussion or dispute of why we don't have enough lady in tech?

Fishackathon. Just realized this week that such even exists. The monitoring device in the 2016 winner team piqued my interest. Does a similar devices on a smaller scale exists in the market for hobbyist? Yes, there is Open Aquarium (based on Arduino) which is, unfortunately, costly and bulky.

Surprised to found that famous illustrator or comic artist, Chen Uen have passed away last year. Parka Blog have a review of his works. While I'm not a fan of his works, I firmly believe that Wuxia comics should definitely drawn in traditional Chinese painting style rather than the typical manga style.
