This post derives the exact analytical bias-correction factor for MAD with $n = 2$. Pragmastat recommends Spread — the Shamos estimator — as a more efficient robust scale estimator that avoids these corrections altogether. Confidence intervals are available via SpreadBounds . pragmastat.dev github.com/AndreyAkinshin/pragmastat I already covered the topic of the unbiased median deviation based on the traditional sample median..

I have been working with AWS API Gateway and Lambda using Go a lot recently. One of the more annoying things about API Gateway and Lambda is the inability to run things locally. As a result I tend to write a lot of unit tests to compensate. This works up till you start doing things like SQL queries as mocking away the database is a less than ideal situation if you are working with raw SQL, which I tend to do since I don’t like most ORM’s. T..

Plain Org v1.4 is now available on the App Store . I was on a long flight recently 🦘, so I gave list and checkbox editing a little love. There's a couple of other minor improvements included. If you haven't heard of Plain Org , it gives you access to org files on iPhone while away from your beloved Emacs . I love org markup, but we (iPhone + org users) are a fairly niche bunch. If you're finding Plain Org useful, please help su....

This is more than a mildly embarrassing post to have to write but it is an interesting example of how habits can bite you hard – so, so hard. I recently wanted to start on an application and actually be current on everything: Rails, Bootstrap, etc. I have long admitted to having issues with respect to "modern" web development (specifically JavaScript / the asset pipeline) and I'm mildly starting to deal with those issues. I began with a..

Service meshes and networking in Kubernetes have their tricks! Working with service meshes is really an interesting concept and sells you the benefits of, well, the service mesh itself, mutual TLS, end-to-end encryption, and more. Unfortunately though, not everything is as straightforward as you might think. In fact, Istio's own documentation page has a full section dedicated to "common issues". These issues are not so evident if you come..

I've been pondering about minimalism, and trying to implement it into my life for quite some time. However, the idea proved itself to be elusive due to various reasons. While this elusiveness can be partly attributed to the nature of the beast, other parts can be attributed to me. The idea minimalism puts forward is an enticing one, which can be simplified as "having no excess, but what you need", which brings many promises and possible o....

With my third booster shot out of the way I’ve felt a bit safer finally going out into the world a bit more and actually experimenting with different work locations. One of the things I love about remote work is being able to work from anywhere, but throughout the pandemic it was impossible to explore this possibility because it simply wasn’t safe to do anything but stay at home.

Hello! It’s been an eventful few weeks months: the job has been quit, the truck has been sold, the California has been left, and the new venture has been started (full-time!). Selling the truck is probably the biggest and most blog-relevant event. Even though I’d already announced my plans to sell it, having legitimately sold it still feels different . One of those things that doesn’t really register until it’s actually happened...
