The Greenwald-Khanna quantile estimator is a classic sequential quantile estimator which has the following features: It allows estimating quantiles with respect to the given precision $\epsilon$. It requires $O(\frac{1}{\epsilon} log(\epsilon N))$ memory in the worst case. It doesn’t require knowledge of the total number of elements in the sequence and the positions of the requested quantiles. In this post, I briefly explain the basic i..

I want you to consider for a moment all the human lifetime wasted in ideological stalemates on the Internet, all that energy, all that anger and frustration. Imagine if you take even a fraction of that time, and put it to creating something constructive instead, learning skills, doing anything meaningful. It boggles the mind, doesn’t it? It must amount to entire human lifetimes every week. Ideology, or in a wider sense, ethics, is all a..

Traditionally, git’s default branch was called master - but this isn’t always true, it’s just a default - and one that’s currently undergoing change. GitHub & GitLab have changed their defaults to main and the git project itself is in the process of doing the same. I have a longstanding git alias - git up - that I use to pull my local checkout up to date with the remote. It’s a shorthand for the following: Change branch to the default....

I have been using Macbook Pro with M1 since the release of the MBP 13" M1 in 2020. And I am huge fan of the new Apple CPU - M1. Time to time I need to do some work on my 2019 16" MBP with Intel Processor (all maxed out), so I keep experience the difference between using those two. On MBP with M1 I can definitely see that the macOS works way more smooth. No more glitches or frozen screens for a few seconds, less heat, less time I hear the ..

Show me a gambler and I’ll show you a loser, show me a hero, and I’ll show you a corpse. Mario Puzo, author of The Godfather Last week we began the “ How to be a game changer ” series. Today, we’ll start answering the question - “Which games to change”, by defining the two main types of games we don’t want to play - zero-sum games and win-lose games. Zero sum games One way to simplify looking at games, is to look at the pos....

In this scholarly biography by Janet L. Nelson, Charlemagne is stripped back from the years of mythologizing and idolizing that have occurred since his death. He is presented as distinctly human, and this book is the first time I have felt I could reasonably understand Charlemagne as the man he was, not the man he has since been painted to be. Moreover, Nelson is excellent in her discussions of Charlemagne’s wives and their roles. For examp..

Building Mach for everyone If Mach engine only benefits people interested in using that engine, and not the broader Zig (and even gamedev) community I would consider that a total failure . Whether you’re interested in using all of Mach, just some of it with your own engine / project, or just the to....

After 20 years in software development, my frustations with watching organizations hurt themselves from bad practices finally boiled over in my article, Reality Driven Development. The response and discussion from Hacker News lead me into the work of Donald Reinertsen, who laid out the math that validated everything I was experiencing. Much of the Scaled Agile Framework is based on his work, which lead into my journey with SAFe 3 years ago...

Have you wanted to generate PDFs from your Python project? Many of the current libraries require designing the document down at the pixel level. Would you be interested in a tool that lets you specify the page layout while it handles the specific details of laying out the text? This week on the show, we talk with Joris Schellekens about his library for creating and manipulating PDFs named borb.

Previously in exploring PL/pgSQL: Strings, arrays, recursion and parsing JSON In my last post I walked through the basics of PL/pgSQL, the embedded procedural language inside of PostgreSQL. It covered simple functions, recursions and parsing. But there was something very obviously missing from that post: a working interpreter. So in this post we'll walk through building a Forth-like language from scratch in PL/pgSQL. We'll be ab....

You are invited to a dinner party. After talking for a while food is served on the table. You pounce. “Haha, suckers!”, you think, and load all the food on your plate and leave nothing but scraps for the hosts. You feel victorious. Serves them right for inviting you into their home. You wolf down the food with ravenous appetite while they look on. That was tasty, but now you got a piece of meat stuck between your teeth so you go to the ba..

In July, the Free Software Foundation (FSF) put out a call for whitepapers about the “philosophical and legal questions” around GitHub’s Copilot . I wanted to write one, but decided not to until encouraged to do so by an employee of the FSF. By that time, I only had five days to write it, so the paper ended being subpar, but I got it in. As to be expected, my paper was not chosen for publication, and I don’t blame them. However, I ..
