This Week I Learned - 2017 Week 05

Last week post or whole series.

Always an interesting CNY holidays. The flood was not as worse as it seems. The weather is good and the air, seems cleaner. I've managed to get some good rest and deep sleep (more on this in #4).

#1 Canonical have launch Ubuntu tutorials, a step-by-step guideline for setting up development or devops related activities. I was surprise that they started the tutorial using Intel Joule 570x (their answer to IoT?) as the reference hardware. With a price tag of USD 369, I failed to see how this development kit is going to gain any traction when compare to Raspberry Pi. Maybe the target audience is not the Maker community but the industry?

#2 I've bought TI MSP430 development kit to learn more about embedded programming. So far,, the only thing I learned is microcontroller or MCU is "computer on a chip" or also known as System on a chip (SoC). Compare to the Arduino, Raspberry Pi, or Beageboard, it's way more low-level and cheaper. Once I've done with this, the next SoC that I will get is the ESP32, the successor to ever popular ESP8266. For the time being, the next step is introductory write-up on the hardware, setup the development board, testing the serial communication, go through the tutorials, and follow these four things to do with new microcontrollers.

I've noticed that there is this M430F1612 chip (square shape) on the launchpad. Feature-wise, it's similar to MSP430G2553 (rectangular shape) but was used for debugging purpose via JTAG from our computer.

I was thinking on getting more MSP430G2553 and stumbled upon this site, FindChip, which can search through all the popular electronic parts resellers. Note that the search links does contains affiliate links. But is a good way to find available stock and prices in one place.

#3 Are we over-dramatize our life or why people need drama in their life? Sometimes, no news is good news. If you ever complain about boring and simple life, you've been trying to mold your life according to a fairy tale. Follow your dream is such a clichéd pieces of advice. Too abstract and too vague. Be more specific, for example, stay healthy by exercising for 30 minutes on 5 days a week.

#4 Interesting idea on restricting exposure of lights can affect your sleep patterns. I've been living in the city for many years and my exposure and computing usage (you brain is kept active and Melatonin production is delayed) have somehow affecting my sleep cycle and thus my health. Maybe I should switch to something like Philips Hue Bulb? Need to readjust my time and remember, bedroom is for sleeping. Is okay to have TV in the room, just for the sake of white noise. Maybe because there is a healthier life without Internet. Remember, there is way to get you hook on an app or site. Off course, there is antidote to that as well.

#5 "Short answer, It doesn't. Long answer, It does not." Regardless the context of the discussion, the comment is both humourous and fscking brilliant. There is a similar saying as well. "To make it short, is a long story". Maybe we should invest our time in writing? While we on writing, be careful when you use the pharase "duly noted". It usually means "heard and ignored" in a sarcastic way or if you add an extran 'l', it becomes "dully" noted, which means you "barely" acknolwdge. To prevent unnecessary misunderstanding, replace it with "Got it, thanks!" (informal) or "Noted, and thanks!" (format).
