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.
