+
+# [Event Driven Architecture](https://pradeeploganathan.com/architecture/event-driven-architecture/)
+
+A long explanation on what Event Driven Architectures are.
+
+Honestly, it is one of my favourite patterns, 'cause it allows high decoupling
+of data. You have one thing creating events and you can have a lot of things
+consuming those events: You can save them directly to the database; you can
+make them go through a summing service, so you have the data read ready; and
+so on.
+
+# [Writing Safe Shell Scripts](https://sipb.mit.edu/doc/safe-shell/)
+
+I've seen a couple of tips like these floating around, so I picked one.
+
+Shell scripts are a hell of lifesaver, giving the initial states for a way to
+automate stuff. But doing it right is a bit hard, and starting it in the safe
+way can save your bacon in the long run -- or, at least, till you find a more
+suitable tool.
+
+# [Rust Dynamic Dispatching deep-dive](https://medium.com/digitalfrontiers/rust-dynamic-dispatching-deep-dive-236a5896e49b)
+
+Dynamic Dispatching is a way to make Rust applications behave like you had
+polymorphism: You attach a trait (interface) to a structure and call methods
+using the trait instead.
+
+I had trouble making it work recently and this explanation -- which is pretty
+complete -- got me back in track.
+
+# [Rust Web Development Tutorial: REST API](https://cloudmaker.dev/how-to-create-a-rest-api-in-rust/)
+
+Actix is all in rage for development web applications in Rust: It basically
+took almost [every position on web frameworks
+benchmark](https://www.techempower.com/benchmarks/) a few months ago and has
+only consolidated its position -- not that the things it does are important
+for CRUDs.
+
+But the tutorial does the full job, explaining not only Actix, but also how to
+plug Diesel, Rust famous ORM, into it.
+
+# [Shlide: a slide deck presentation tool written in pure bash](https://github.com/icyphox/shlide)
+
+Say goodbye to the problems of resolution! Do the hipster thing and instead of
+using graphics, do everything in the console.
+
+# [An Open-Source Collection of +200 Algorithmic Flash Cards to Help you Preparing your Algorithm & Data Structure Interview](https://github.com/teivah/algodeck)
+
+While some people work on those "Awesome X", some people actually builds cards
+for you to learn about algorithms and related knowledge.
+
+And it's all open source.
+
+# [How to Give a Great Presentation: Timeless Advice from a Legendary Adman, 1981](https://www.brainpickings.org/2012/12/20/writing-that-works-roman/)
+
+Working one a presentation? Thinking on doing some online presentation in
+these days of "stay at home"?
+
+On a personal note, I've been doing presentations for over two years already,
+and most of the stuff I learnt in the field instead of some technical list.
+But I see that small tips like these really do help, specially when you see
+people actually paying attention (well, at least, when you're not doing this
+online).
+
+# [Writing Runbook Documentation When You’re An SRE](https://www.transposit.com/blog/2020.01.30-writing-runbook-documentation-when-youre-an-sre/)
+
+I worked with Runbooks once and I think they are awesome: "If you find this
+problem, do this".
+
+The only "but" I could add to this is that it focused on SRE people, and I do
+believe who should write those are the _developers_: they are the ones that
+know why a save file operation failed.
+
+Sadly, this is not quite true, 'cause developers tend to ignore errors, or use
+some tool that doesn't provide a good view on where things can fail -- or,
+worse, can fail without notifying the developer. In this case, the Runbook
+should be built with the SRE _and_ developers, so both can learn how the
+application work and where it can fail.
