This Week I Learned 2018 - Week 45

Last week post or something else from the old archive.

手写的温度还在吗?放慢生活节奏,回归朴实。

What would happened to Red Hat after IBM have acquired it? (via HN) I'm not sure Red Hat will be still Red Hat (you can work your own FOSS stuff even if it detriment to the company) since IBM is well-known for aggressive creating and protecting its patents portfolio. FOSS is not its core business values, it's just another department. But question remains, why purchased Red Hat? They need to control and be a major player as a cloud vendor compare to Amazon, Microsoft, and Google. Red Hat, with its full FOSS stack, libraries, or tools, provides a platform for them.

Build your own professional-grade audio amp on the sort of cheap (via HN), worth it? Not really, unless you're really into learning (great things to do with your kids) and assembly the whole thing. Most of the DIY kits are way too pricey (Cmoy is the exception) and not worth the effort of getting the whole thing from Ali Express. Again, it's not the audio equipment itself, you still needs to manage the audio room or environment with acoustic panels. Be warned, stop when you can and don't buy into the whole system, cables, furniture, panels, and misc. Unless you can hear the differences (doubt so in my case), you're making money from audio, or friscking rich, don't join the audiophile madness.

Why does privacy matter or I'm not motivated enough to take privacy seriously? Well, if you want to prevent something like Social Credit System from the big brother.

Why kick timing is important in swimming? I intrigued by so many coaches overlook the kick timing aspect in the swimming drill. It seemed the focus was on building the stamina through drill rather than the technique and style. With the right kick timing that syncs with hand actions (catch, pull, exit, and recovery). Sun Yang, is a well-known swimmer which utilizes all three kick timing techniques depends on his breathing patterns as shown in his 1500m freestyle world record in 2012 Olympics race. 2-beat or 4-beat kick for the first 1400m and 6-beat kick for the last 100m.

So You Wanna Be a Chef? (via HN) Why the world need more honesty so young people can calibrate their own expectation in their career of choice? If not, we're setting them up for unreasonable failed expectation and brutal honestly about life, especially when come to financial (high student debt) and emotional reality (unreciprocate passion) . While having passion is good for your career of choice, but this does not means you can work for free or being undercharged.

Was Hindu god, Ganesha created to curb Buddhism? Debatable view but one thing for sure, Buddhism influence was limited by Adi Shankara in the 8th century.

When should you go to bed? The right question to ask is what time you want to wake up instead.

What is your books reading strategy? This approach is probably the most comprehensive I've seen so far.


Upgrading to Ubuntu 18.10 (Cosmic Cuttlefish)

Ubuntu 18.10 was released last week and I've managed to upgrade most of my machines to this newer version. Compare to upgrade experience of 18.04, no show stopper was encountered. Reading through the release notes, it's not a major releases, just some upgrades to existing packages. However, some interesting items caught my attention.

1/ GNOME Disks now supports VeraCrypt. The name sounds familiar until I googled it up. It seemed that VeraCrypt is the fork version of the discontinued TrueCrypt, a popular disk encryption software many moons ago. A few old acquaintances love to use this software to stash their favourite collections.

2/ Sounds over-amplication. This is a welcome needed feature especially if you have lots of music files with incorrect volume range. Previous workaround was to play it through VLC which support this.
