This Week I Learned - 2017 Week 31

Another week, another post. Looking for last week post or something from the archive?


The annual nature appreciation week. Didn't realize that such a place exists in this country. I really need to brush up my local geographical knowledge. However, nature should be explore in its natural form, as in camping, not from some resort built near to it.  And the food, that's a lot to be desired. Pity though.


Fighting with idiotic MySQL 2013 lost connection error for the past week with the Docker instance. Tried different approaches to tweak the server so the database restoration process won't kept throwing such error. In the end, proceed with Plan B approach by changing the mysqldump script so that it will skip extended insert. The side effect of such approach is that the dump file will be bigger and database reloading will take longer. But something working even though slow is way better that something broken. In coming weeks, will look into different approaches, for example, putting the whole test databases in memory (using tmpfs approach which can speed up testing), mysqlpdump (parallel version of mysqldump), or using ProxySQL.


Scientific communication as sequential art. I hope one day that the academic world will publish literature in more readable and accessible way. Actually it's not that hard, some common sense with certain good "taste".


Unit circle. After living for so long, I finally grok trigonometry and understand what the heck is sine, cosine, and tangent.


If you've fork a repository and want to sync from the remote upstream? Two steps. First, set up the remote upstream URL. Second, sync the fork from the upstream.
