Tam Le letam

I’ve been ~~obsessing~~ interested in air quality for the last 2 months (pretty much because I saw that famous DHH talk and the Awair Element gamify it - but I highly recommend it to check if the changes you’re making are actually working). Here are a few things to consider:

I recommend getting a ultrasonic one just because the maintenance is just way easier. And your should REALLY think about maintenance (you don't want a filter you need to change filters every month and have a hard time cleaning it). The ones I recommend are:
- Levoit ultrasonic 300S: huge 6L tank, good for bedrooms and smaller rooms, super easy to fill and clean. Works with Alexa and Google.
Levoit ultrasonic LV600S: huge 6L tank, generates a lot of umidity, ideal for bigger rooms, dece

Adjusting child processes for PHP-FPM (Nginx)

When setting these options consider the following:

How long is your average request?
What is the maximum number of simultaneous visitors the site(s) get?
How much memory on average does each child process consume?

Determine if the max_children limit has been reached.

sudo grep max_children /var/log/php?.?-fpm.log.1 /var/log/php?.?-fpm.log

OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

NERDTree

o.......Open files, directories and bookmarks....................|NERDTree-o|
go......Open selected file, but leave cursor in the NERDTree.....|NERDTree-go|
t.......Open selected node/bookmark in a new tab.................|NERDTree-t|
T.......Same as 't' but keep the focus on the current tab........|NERDTree-T|
i.......Open selected file in a split window.....................|NERDTree-i|
gi......Same as i, but leave the cursor on the NERDTree..........|NERDTree-gi|
s.......Open selected file in a new vsplit.......................|NERDTree-s|
gs......Same as s, but leave the cursor on the NERDTree..........|NERDTree-gs|

O.......Recursively open the selected directory..................|NERDTree-O|

	## Context

	1. Coding in Typescript for 2 year, 3 years on NodeJS before that, 15+ years in general (mostly Java)
	2. Spent about 6 months on VS Code and 6 month with WebStorm
	3. Cost is not a factor (company provides JetBrain licenses)
	4. What my projects look like: back-end, OOP, Typescript, Mocha, ESLint, pnpm and monorepos (~15 packages, ~300 files)

	## WebStorm does better

	How to convert a video file to an animated GIF on Linux:

	Install required software:
	apt-get install ffmpeg gifsicle imagemagick:
	Convert the video file to a series of small images:
	mkdir /tmp/gif/
	ffmpeg -i YOURVIDEOFILE.mp4 -r 10 /tmp/gif/out%04d.gif
	Combine these images together into a GIF animation:
	gifsicle –delay=10 –loop /tmp/gif/*.gif > animation.gif
	Optimise the GIF animation so the file size is smaller:
