Learning Maths Where can you learn math Math Foundations from Scratch is part of a large course on AI, but nice and concise Robotics 501: Mathematics for Robotics for a more unexplored area of maths applied to robotics The Book of Proof - I love this one.

There are multiple way to work with Google Calendar. I choose to not work with the private key thing for now. Instead I will try to use the option working with the .ics format. This should give a relatively universal solution for all kind of calendars. I don’t want a locked-in solution that would work only for Google. (Not that this would very surprising if in the end we find out we have to do something custom because it’s google)...

So, i had this planned for a while to add some more math content to this blog. Mostly for the content I do in french, where I do a lot of school related content for the kids but also for here, in english, where I will likely need it later when adding content about recommender system and other ML topics. Anyway, figured out that Latex is the way to go usually when you want to do some maths in a paper, and well, turns out there is a library for this name Katex and it’s super simple to integrate in Hugo....

A known thing - I am just posting this here as a reference Beautiful is better than ugly. Explicit is better than implicit. Simple is better than complex. Complex is better than complicated. Flat is better than nested. Sparse is better than dense. Readability counts. Special cases aren’t special enough to break the rules. Although practicality beats purity. Errors should never pass silently. Unless explicitly silenced. In the face of ambiguity, refuse the temptation to guess....

Keeping Secrets Secret in Python Based on an article by originally published by Jason Goldberger but unfortunately the original is not online anymore so I have rewritten a short version, since this is something I have been looking for a while. Fernet has one classmethod called generate_key() and two instance methods encrypt(plaintext_binary) and decrypt(cipher_binary). Step 1 : Generate a key Generate a key and save it to the OS’s environment variables:...

Kubernetes has multiple moving parts. Here is an short article aiming at mapping all this to create some clarity. Some Basic Vocabulary Nothing fancy but let’s get this out of the way. Nodes A node can be a physical machine or a virtual machine. Cluster A cluster is a group of nodes Container runtime Docker (or runC) Pod A pod is a group of containers - that together form a logical application....

A refactored digest of my reading of the month. A short introduction to give a bit of context : I have been looking for a way to share on a regular basis some of my learnings. I tend to go through a pretty large amount of content as part of my work and in general. So here I will try to provide it as a structured digest. The goal is to provide an interesting selection of content both practical and conceptual to help advancing how to use tech to solve real problems....

We have a bone to pick with the printer industry. Today, you can litteraly print anything… … as long as it is not on paper. You can 3D print your own laptop parts or even a 3D chocolate cake. But If you dare to print a black and white A4, then, it’s suddenly it’s super high tech… Ink Cartridges Are A Scam An ink cartridge cost about 1$ but is sold up to 100 time its original cost....

Ok this is an experimental post. I realised I collect a lot of information during the week. I don’t have the time to make sense of it immediately, in a way that would be deep, and reasonate with the global zeigest… So, instead of pilling drafts on my drive, I decided to publish it as a weekly review of the stuff I collect. and will later, if time allow, get back to it....

Patience. Grit. Perseverance. Borderline Stubbornness. The number one reason people failed, especially when it comes to content marketing and organic reach, is a lack of patience and will try one more time. Statistics will be your first enemy The beauty of digital marketing is that it brings you statistics, and you know pretty much what’s happening with your content, which at the beginning, is not much. It is very tempting to let it go, drop the pace slowly, miss a few milestones until your plans to post daily on your blog are gone, or you let your twitter engagement running at an all time low....
