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.

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..

Refactoring UI is one of the best things I've read this year in terms of stuff learned, I feel like I've become a way better designer after reading every chapter, the thing I like about it is that it focuses a lot on the little things that when used together makes an average website 10x better

You acquire a skill or experience through time and effort, then downplay the impact of writing and sharing the learning process. Professionals seem naturally to imagine a high bar for what is worth writing about. I think that's misguided. This article is not criticism of folks with these beliefs, but rather encouragement for folks looking for a reason to write. There are (at least) a few concrete reasons to write about what you've lea....

Have you ever really sat down and thought about Batman? I had a surplus of spare time on my hands recently, so I went back and played through Batman: Arkham City. When it originally came out, people consistently told me it was good, but I never got around to playing it because I just never cared about superhero comics or any other type of cape media. It’s a middling game - lot’s of time wasting minigames - but I’m not here to elaborate on t..

Masen’ka (or Mary) is Nabokov’s debut novel. It was written when he was in his twenties, living as an émigré in Berlin, just like the story’s protagonist. In the introduction of my Italian edition (Adelphi), the author admits that some life events poured into the narration. The depiction of Ganin’s life in a pension filled with fellow Russian ex-pats, and the relationships between them, is undoubtedly reminiscent of Nabokov’s own experience..
