This Week I Learned - 2016 Week 06

Previous post.

#1 PatternCraft. Learning Design Pattern through StarCraft. Never underestimate the importance of Software Metaphors in abstracting software engineering concepts.

#2 Ask HN: Best curated newsletters? Need a way to reduce your time from the net but at the same time still fear of missing out? Pick your favourite curated newsletters. Cron.weekly seems to have plenty of links which I've found interesting if you're looking into system administration. Mandarin Weekly caught my attention as well.

#3 How Git Merging turns you into a GITar Hero. Till today, I still don't understand why developers still fail to see the benefit of Git Rebasing. Maybe the complexity of the merged trees indicates productivity or sense of accomplishment? You know, software engineers tends to over-analyze and over-engineer.

#4 Linux Performance Analysis in 60,000 Milliseconds. Using uptime, dmesg, vmstat, mpstat, pidstat, iostat, free, sar, and top command, you can have an overview of the resource usage of a system. Don't want to go through the hassle of all these commands? Just use Glances, web or console-based monitoring tools written in Python. Perhaps, htop, an interactive process viewer or iotop, disk I/O status monitoring tool.

#5 Ping Sweep. Fun activity to do with nephews during CNY. We all learn how to find all available hosts that were connecting to the Access Point (AP). From the list of IP addresses, divide the these these hosts into mobile and computing devices. Have fun times scanning the network where they both overloaded the Wifi router by "nmapping" the network. The seed of learning have been planted, is really up to them to explore further. Hopefully, by the next CNY, they will move ahead even further and know which particular field in IT they want to venture into.

#6 Janice Kaplin: "The Gratitude Diaries". Is time to reflect and appreciate on what we have and where we are. How? Keep a gratitude journal.

#7 Today I Learned (TIL) is a famous subreddit. For technology related (programming or system administration), there are TIL collections created by Josh Branchaud, hashrocket, Jake Worth, and thoughtbot.
