Introduction If you can write a for-loop, you can do statistics. - Jake Vanderplas A lot of developers shy away from problems which involve statistics or probability. Which is shameful since in today’s data-rich environment, you can gain a lot of insights from data. In this blog post, I’ll show you how to write a simulation tool which requires no knowledge in statistics or probability. Simulations are easy to write and can be a very ..

Since I’ve never found a complete and easy tutorial on how to setup an encrypted account using the default macOS/iOS Mail.app, I’ll try to explain my setup and how I made this. Keeping things separate for the two type of encryption, an easy and less secure way: S/MIME, and the more robust and secure PGP. I’m using both on my macOS/iOS devices, with two different apps, when I want to use a friendly way and I don’t have to share important inf..

This is an early attempt at blender from 2021. It started with a drawing that I loved. I’ve poked around Google Images but so far I haven’t found the original artist. I quickly modeled a few things, trying to create a more 3d look rather than sticking with the more stylized look. I’m not sure if this was ultimately the right choice. The moon was a little tricky to get right and I haven’t nailed the look of low light.

Figure 1. Asciidoc. I’ve been using reStructuredText for writing on this blog, because it has lots of built-in features that markdown doesn’t. However, reStructuredText’s actual syntax is a bit… fiddly - particularly its non-atx headings, too many things relying on lining up white space, etc… If I don’t use it for a bit, I have to look up or copy & paste all the advanced syntax. I’d prefer to use AsciiDoc, as it has all the extra....

Preface This is a tale of the intersection between thermal physics, cosmology, and a tiny amount of computer science to answer a seemingly innocuous question: “How strong does a password need to be for it to be physically impossible to brute-force, ever?” TLDR at the bottom. Note: this post contains equations. Since none of the equations were long or complex, I decided to just write them out in code blocks instead of using images ....

MP² quantile estimator: estimating the moving median without storing values

In one of the previous posts, I described the P² quantile estimator. It allows estimating quantiles on a stream of numbers without storing them. Such sequential (streaming/online) quantile estimators are useful in software telemetry because they help to evaluate the median and other distribution quantiles without a noticeable memory footprint. After the publication, I got a lot of questions about moving sequential quantile estimators.....

The First 90 Days” by Michael D. Watkins is a book on leadership transition that I had delivered to me from my new manager at the role I just took on at a new company. I read the book ahead of starting last month but finally got around to sitting down and writing out my summary. The book provides a comprehensive framework for making a successful transition, with practical advice and tips that are applicable to any industry or organization.

Background : I decided I should get a small portable boombox to practice my dope dance moves . I currently still suck because I think I spend more time computering than out on the floor.

GNU Stow is a tool from the GNU Project presenting itself as a symbolic link manager. As a reminder, a symbolic link is a shortcut to a file stored elsewhere on the disk. Thus, reading or writing a symbolic link will redirect to the original file. On the other hand, deleting the symbolic link does not delete the original file. Stow allows you to better manage the numerous configuration files present in Linux by creating symbolic lin..

You sent me a Word doc on Wed 18 Mar 2020. Inside the doc was a copy/paste of a very large slack conversation. Inside the conversation was the complete contents of our production incidents channel on the morning of Mon 16 Mar. I glanced at the document, but was busy - our systems were straining and crashing because COVID-19 had erupted and US schools had closed, and teachers turned to Remind at scales we had never seen. Teachers have r....

If you’re familiar with the Rails ecosystem, the names Devise and OmniAuth might ring a bell: the former is a gem that handles (nearly) everything related to authentication; coupled with the latter, it makes implementing popular Social Login providers (e.g. Login with Facebook, or Twitter, or GitHub…) a breeze.
