• Jiri Eischmann: Bisecting Regressions in Fedora Silverblue

  I know that some blog posts on this topic have already been published, but nevertheless I have decided to share my real-life experience of bisecting regressions in Fedora Silverblue.

  My work laptop, Dell XPS 13 Plus, has an defective chip maker Intel IPU6 webcam. It still lacks upstream drivers, so I have to use RPMFusion packages containing Intel’s software stack to ensure the webcam’s functionality.

  Dear syslog-ng users,

  This is the 117th issue of syslog-ng Insider, a monthly newsletter that brings you syslog-ng-related news.

• Hackaday ☛ Linux Fu: Curling C

  Sometimes, it pays to read the man pages of commands you use often. There might be a gem hidden in there that you don’t know about. Case in point: I’ve used curl (technically, cURL, but I’m going to stick with curl) many times to grab data from some website or otherwise make a web request. But what happens if you want to do the same thing from a C program? Well, you could be lazy and just spawn a copy of curl. But it turns out curl has a trick up its sleeve that can help you. If only I’d read the man page sooner!

• Barry Kauler ☛ woofV topological sort

  If you have ever used Woof, the Puppy-builder, or even as a user of Puppy, you may be familiar with /root/.packages/woof-installed-packages. Or, in recent Woof-CE-built pups, it is at /var/packages/woof-installed-packages.

  This has a list of the packages that are "builtin", in "Puppy DB" format. By builtin, that means that are in the SFS(s); in the case of EasyOS that is 'easy.sfs'. Here is an example of one line in that file:

• KDAB ☛ Optimizing Embedded Product Design

  Choosing the right system-on-chip (SoC) is probably your first consideration when designing an embedded product, followed closely by deciding whether to use an off-the-shelf board or design your own.

• R

  • Rlang ☛ Discrimination by proxy (a real case study)

    Yesterday, with Laurence Barry, we posted a blog post “Who benefits from data sharing?” explaining why data sharing, in insurance, could end mutualization.

  • Rlang ☛ Conquering R’s Apply Family: Your Guide to apply(), lapply(), sapply(), and tapply()

    Welcome, fellow R warriors! Today, we delve into the heart of vectorized operations with R’s “apply” family: apply(), lapply(), sapply(), and tapply().

  • Rlang ☛ Introducing rOpenSci Champions – Cohort 2023-2024

    The rOpenSci Champions Program starts this 2024 with a new cohort of Champions. We are pleased to introduce you to our Champions and their projects!

  • Creating and Searching Embeddings in Java with Hugging Face API

    In the field of natural language processing (NLP), embeddings play a crucial role in representing text data in a numerical format that machine learning models can understand. Embeddings capture semantic information about words, phrases, or sentences, enabling various NLP tasks such as sentiment analysis, text classification, and machine translation.
