+# (Managing Hierarchical Data in MySQL)[http://mikehillyer.com/articles/managing-hierarchical-data-in-mysql/]
+
+A bunch of tips on how to manage nested/hierarchical information in MySQL.
+While the storage format could be used in any database, it seems the insertion
+part in the post is MySQL specific.
+
+Curious, nonetheless.
+
+# [The Commons Clause will destroy open source](https://drewdevault.com/2018/08/22/Commons-clause-will-destroy-open-source.html)
+
+While I don't agree with Drew in some points (mostly the things he rants
+about), and while I don't think, on the surface, that the Commons Clause may
+destroy open source, his words are a cautionary tale about picking the right
+license[^1].
+
+# [Guide to starting with Clojure](https://grison.me/2020/04/04/starting-with-clojure/)
+
+It's been too long since I saw a very detailed introduction of a language like
+this. Explaining installs, IDE/Editor configuration, a short description of
+the language, a toy problem and a way to build and deploy the result.
+
+Really complete -- and, on the plus side, it's Clojure!
+
+# [The Svelte Compiler Handbook](https://lihautan.com/the-svelte-compiler-handbook/)
+
+While related to Svelte -- the JavaScript templating language -- what it
+describes is pretty close to what every compiler do, in a high level, even if
+some do more stuff, like Rust having two more steps before the code
+generation, for optimization.
+
+# [Language Design: Stop Using \<\> for Generics](https://soc.me/languages/stop-using-for-generics)
+
+Let's get into some controversy, shall we?
+
+One the major points of Clojure is exactly how it pick one single pair for
+each different aspect, contrary to Lisp, which used parenthesis for
+everything.
+
+So, what is being described here is to use `[]` instead of `<>` for generics.
+But wouldn't that clash with array access? Sure, that's why array access
+should be `()`. But wouldn't that clash with function calling? Sure, that's
+why function calling should be... should be what again? Nothing? So we let it
+clash?
+
+"`<>` is hard for compilers to parse". Oh, poor compiwer, it is weaving a bad
+time? Newsflash, the job of a compiler _is_ to take the hard work and leave
+the simpler thing to users; the harder it does its work, the easier it is for
+their users. If the users can clearly see generics with `<>` -- because it is
+different from everything else -- then it is good.[^2]
+
+# [Your configs suck? Try a real programming language.](https://beepb00p.xyz/configs-suck.html)
+
+Another controversy, just for fun.
+
+Ok, so config formats are bad 'cause you can't replicate some stuff -- I can
+agree with that, imagine having to copy and paste the same value over and
+over?
+
+But the problem is: Using a "real programming language" for configuration may
+also have a problem: you need to cut a lot of stuff. Django uses Python itself
+as a configuration -- and, again, I can agree with that, 'cause it allows one
+to have a default configuration and just import it and override things for
+your local execution -- but it doesn't block running anything. Worse, because
+you can import things into the configuration file, one project that gets
+compromised will _always_ run the code.
+
+Again, I agree with a lot of points, including the fact that the current
+formats for configuration files are bad, but using a programming language for
+it is not the solution. Besides, it is possible to overcome those problems
+with better configuration settings themselves than the format; as hard as it
+is.
+
+# [Security and Privacy Implications of Zoom](https://www.schneier.com/blog/archives/2020/04/security_and_pr_1.html)
+
+While articles about the raise of Zoom and its problems popping everywhere,
+but Bruce Schneier, the father of internet security, made a post with all its
+problems, from privacy to security.
+
+# [My tools are going Rusty](https://elliehuxtable.com/my-tools-are-pretty-rusty/)
+
+A short summary of common Unix/Posix/GNU tools written in Rust.
+
+# [How SEO Ruined the Internet](https://www.superhighway98.com/seo)
+
+Yes, everybody knows how the current trend of creating content focused on
+producing better search results -- instead of, say, better quality content
+that _should_ be indexed due its quality -- basically made the internet a
+terrible place.
+
+This post describes some of the effects of this focus on the general internet
+content.

+[^1]: This was weirdly timed with a presentation I finished talking about
+  licenses -- it's in Portuguese, and I haven't present it yet, but at some
+  point there will be a companion post for it, even in English.
+
+[^2]: Personally, using Scala as an example of "doing right" feels really
+  wrong. Scala does _a lot_ wrong, I don't freaking care how much you like
+  Scala. Also, saying Python uses `[]` for generics is wrong 'cause Python
+  does _not_ have generics.
