Here is the monthly newsletter from the Micro blog.

2019-09-02: Lovely. https://leon-kim.com/
2019-09-02: Old times good times: A Brief Timeline of the History of Blogging. Although I came late to the party (around 2006), I remember all those emerging blogs from the 2000s, I mean, before the advent of social networks. Then came Twitter, Blogger and Tumblr.

2019-09-02: Random Forests, Decision Trees, and Categorical Predictors: The “Absent Levels” Problem (PDF).> This problem occurs whenever there is an indeterminacy over how to handle an observation that has reached a categorical split which was determined when the observation in question’s level was absent during training.TL;DR No feature engineering heuristics seem to really help mitigate this kind problem.
2019-09-02: eBay’s TSV Utilities: Command line tools for large, tabular data files. Filtering, statistics, sampling, joins and more.
2019-09-03: > The good things in a community site come from people more than technology; it’s mainly in the prevention of bad things that technology comes into play. Technology certainly can enhance discussion. Nested comments do, for example. But I’d rather use a site with primitive features and smart, nice users than a more advanced one whose users were idiots or trolls. — Paul Graham, What I’ve learned from Hacker News

2019-09-04: Lisp people: What’s your go-to language for when you want to write a quick script. I for one do most of my scripting stuff using Bash, sed/awk, and Python. However, it looks like some folks tend to rely on Clojure, various flavours of Scheme, CL, or even Perl 6 (but why?).
2019-09-04: Robust Arithmetic in Computational Geometry.
2019-09-04: Static Sites with Hugo, Tachyons, and Netlify.

2019-09-05: Early in the morning, I decided to reformat my old notes from various formats (RST, MD, TXT) to Org. It took me more than two hours to make things look like they weren’t writtent in 2005 on Linux!
2019-09-05: I have been using my bluetooth Magick Keyboard at my office since 3 weeks now, and it’s kinda difficult to write on the Macbook built-in keyboard right now. Or I may just be tired. Anyway, to reiterate what I was saying last year, this is definitely a very good keyboard.
2019-09-05: So now I know why I lost several Go of free space on my HD:

2019-09-06: > You’ll be fighting the compiler to the end as long as you have writes to uint8t arrays in your core loops. — Incrementing vectors.
2019-09-06: Apprently, the TAB key of my built-in keyboard started to screw up seriously. Not a bid deal since I’m using an external keyword at my offcie, but in order to anticipate any definitive failure, I remapped my right option key to TAB. Not a bad deal after all, since I never use this modification key. Now, for switching between app, I can simply use my two hands: left for ⌘ and right for ⌥ .
2019-09-06: Not sure I deserve a medal this morning, but at least I reached the point where Emacs told me my code looks like a giant mess in a Git repo.So, after a bit of googling, I’m now reading How I Lint My Python, although Emacs does it all for free.

2019-09-10: Fira code is now v2. I’m still loving Iosevka, so I won’t fall back to Fira Code for my editor and terminal, but this surely remains my preferred monospace font for technical writings.

2019-09-18: While I’m really impressed with the Eisvogel template for my Org->PDF toolchain—the rendered listings remember me of the Nord theme that I use in my terminal and under Emacs or Vim), I’m also investigating other alternatives. Here are is a nice candidate: arabica, but that may well be too much for what I need.

2019-09-20: Hugo-theme-docdock looks like a very nice theme for project documentation.
2019-09-21: I’m currently processing all my blog posts — cleaning things here and there. And so I was thinking that a lot of code snippets I post on this blog could be rendered as Gist, as Hugo offers a nice shortcode for that specific purpose. So here we go: Compare to the original version.
2019-09-21: Quite a big work of revision (reformatting and proofreading, essentially):
I’m only halfway thu, though.
