I’ve found an interesting question on Twitter, recently. Is there any performance impact of using FILTER in SQL (PostgreSQL, specifically), or is it just syntax sugar for a CASE expression in an aggregate function? As a quick reminder, FILTER is an awesome standard SQL extension to filter out values before aggregating them in SQL. This … Continue reading The Performance Impact of SQL’s FILTER Clause →

Last month I have been developing a Rust tool to create container images from Conda environments, without going through Docker. It was a wild trip down the rabbit hole of OCI images, so I thought I’d share part of the adventure here. Enjoy! But why? If you are used to building container images, you might be asking yourself why on earth someone would want to deviate from the well-trodden path of Dockerfiles.
This is a very brief post announcing a fascinating discovery. It appears to be possible to use the cosine similarity approach powering explore2.marginalia.nu as a substitute for the link graph in an eigenvector-based ranking algorithm (i.e. PageRank). The original PageRank algorithm can be conceptualized as a simulation of where a random visitor would end up if they randomly clicked links on websites. With this model in mind, the modifi..
FOSDEM 2023 - danielpecos.com - 3 years ago - spa
This weekend I traveled to Brussels to attend FOSDEM 2023 , although only for the first day (Saturday 4th, 2023). It hasn’t been my first one, but it has been the first massive event I have attended after the COVID-19 pandemic. After the morning keynote, I had a quick look around the buildings where the event was hosted to visit the different stands of the many sponsors of the conference. Among the most interesting ones (for me personal....

There are several ways on how to schedule repeatable jobs in Nest.js. The official documentation suggests using @nestjs/schedule. This library offers an elegant CRON-based API, which should be familiar to most Nest.js developers. Look at how neat and simple this declarative API is: @Injectable() export class MyService { @Cron("* * * * * *") handleCron() { console.log("CRON is triggered"); } } With one line, we now have a method which will ..

In a C# library I’ve been working on, I wanted to use C# 9.0’s init keyword. Quoting the documentation : The init keyword defines an accessor method in a property or indexer. An init-only setter assigns a value to the property or the indexer element only during object construction. This enforces immutability so that once the object is initialized, it can’t be changed again. Consider the following class: public class Person ..

It definitely feels like Twitter is slowly dying. I have used Twitter for years, definitely more as a consumer than a publisher. During this time I have refined the accounts I follow to provide a clean and useful stream of information. This was aided by the use of Flamingo as my client of choice which provided a feed free of adverts and cruft.
