Despite its name suggesting otherwise, Dune II was a first – a real-time strategy game that sprang out of the box with almost every gameplay attribute and control system seen in every RTS since. In direct lineage, it was the father of the globally successful Command & Conquer franchise, in that its code was used as a basis of the first game of the series. Yet in terms of wider influence, the battles first fought out on the vibrant sands of ..

Kernel density estimation boundary correction: reflection (ggplot2 v3.4.0)

eng
Kernel density estimation (KDE) is a popular way to approximate a distribution based on the given data. However, it has several flaws. One of the most significant flaws is that it extends the support of the distribution. It is pretty unfortunate: even if we know the actual range of supported values, KDE provides non-zero density values for the regions where no values exist. It is obviously an inaccurate estimation. The procedure of adjustin..

I’m well aware that I may have a bit of an obsession with fonts . I don’t think that’s too unusual for someone who works in tech, however. Sites like Programming Fonts exist to let people test drive and compare a bunch of different fonts. Just for fun, I thought I’d write up some of the features I look for in a programming font that I’ve come to deliberately pick out. Critical letter forms: i, I, l, 1; o, O, 0 # These are probably....

The other day we did a .NET 7 Spotlight event at this month’s DevRomagna meetup. The speakers were Ugo Lattanzi and me. In my session, I chose to talk about my top 7 new features in .NET 7 (pun intended.) What follows is a mix of my preparation notes and what I ended up really saying 1 . 1. Performance Since the initial release of “new dotnet” (.NET Core), performance has always been a critical goal for the .NET team. Starting wit..

Git can be confusing. Git can be scary. Git CLI may be the least intuitive tool you have to use on a daily basis. But also Git is a wonderfully simple and cleverly designed version control system that definitely deserves its popularity. To prove this point I invite you to implement your own tiny Git that would be able to create a local repository, commit a single file to it, view commit logs and checkout a certain revision of that file.

Using Polars on results from DuckDB's Arrow interface in Rust

I found myself wanting to manipulate/compute a large Arrow result set from a DuckDB query in Rust. I first wrote code to iterate over these results and compute what I needed, but the result was a lot of code that ran slowly and was cumbersome to write. I decided to reach for Polars instead. The end result is way less code that is much more performant. I also have the Polars API to work with on any result set from DuckDB, which lets me itera..

Ever since I wrote Clojure needs a Rails, folks reach out to ask for my opinion on their web framework for Clojure. What's clear from these discussions is a lot of software developers have no idea what a framework is.

Fixing apt: Key is stored in legacy trusted.gpg keyring Warnings

If you see messages like this when running APT updated on Debian/Ubuntu systems: W: https://download.virtualbox.org/virtualbox/debian/dists/jammy/InRelease: Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details. This is because using apt-key - particularly the mechanism where it dumps all its keys into one large file (/etc/apt/trusted.gpg) - is a bad idea and deprecat....

Wrapped by Spotify, the 2022 edition just landed in my mailbox. This year I listened to twenty-four different genres. My favorite was Indie Jazz, followed by Hip Hop, Jazz, Electronica and Rock. I am a little puzzled about that Hip Hop in second place. In total, I spent 14143 minutes listening to music, 80 percent more than other listeners in Italy did. My favorite track was Fear Of The Dawn by Jack White, followed by The Beginning by..

Surveys by Common Sense Media and the Consumer Mobility Report both state a large majority Americans sleep next to their phone or with their phone in hand. According to a 2019 Statista survey , 44% of participants reported feeling some anxiety when separated from their phone (not the same thing as the smartphone itself causing anxiety ). This isn’t a public decrying of how we are hopelessly addicted to our phones.

In a previous post we shared some suggestions for how to adjust a Rails application to make it run better in a containerized setting. In this post I'd like to explore the opposite relationship: five changes we have made to our Kubernetes clusters to better accommodate Rails workloads and workflows. All of these ideas can be relevant to non-Rails apps too! Selecting the right deployment strategies The two deployment strategies Kubernetes....

Marcus Hutchins on Mastodon: What I missed about Mastodon was its very different culture. Ad-driven social media platforms are willing to tolerate monumental volumes of abusive users. They’ve discovered the same thing the Mainstream Media did: negative emotions grip people’s attention harder than positive ones. Hate and fear drives engagement, and engagement drives ad impressions. More here . I have been on Mastodon for a few week..
