I'm a robotics researcher. My interests include cybersecurity, repeatable & reproducible research, as well as open source robotics and rust programing.

  • One thing I appreciate about NixOS is the ability to use overlays and override package sources. For example, overlays can be used to selectively install unstable and stable packages alongside each other:

    While there may be caveats, this approach has been working for me just fine, as I can install VSCode from unstable to get the most recent monthly releases as they roll out, but then pin the rest of my desktop environment to stable to limit anything else shifting underneath me unexpectedly.

  • If there was a simple Debian based distro that I could declaratively manage via a single config file, I think I'd try it. I.e. not using Puppet or Chef that can only bootstrap a system state, but something to truly manage a system's entire life cycle, including removing packages and anything littering the system file tree. But since there isn't, I'm using NixOS instead.

    Having a DSL to declare my entire system install, that I can revision control like any other software project, has been convenient for self documenting my setup and changes/fixes over time. Modularizing that config has been great for managing multiple host machines synchronously, so both my laptop and desktop feel the same without extra admin work.

    Nixpkgs also bolsters a lot of bleeding edge releases for the majority of FOSS packages I use, which I'm still getting used to. And because of how the packaging works, it's also trivial to config the packages to build from customer sources or with custom features. E.g. enabling load monitoring for Nvidia GPUs from btop that many distros don't ship by default.

  • NixOS Web Services with Cloudflared: A Complete Guide - YouTube

  • Yeah, the centralization of public Internet infrastructure around Cloud flare has been concerning, not only as a single point of failure but also in terms of consolidation of trust.

    As a prior student workout a public IP deep behind several NATs, with little funds for self hosting hobbies, these kinds of tunnel services were a handy gateway in getting started.

    Although, I hope ISP adoption of IPv6 or cheaper bandwidth quotas for VPS providers help compete on this front for self hosting networking.

  • Too bad you have to rely on cloudflare to then manage your domain to utilize this feature, like if it's just a demo for a one off project.

  • From NixOS to Ubuntu (Jon Seager Ubuntu VP Engineering)

  • I've been straddling between NixOS and a Debian derivative for a while recently. Using nix, I really enjoy managing my system using declarative code, like I would for any other software infrastructure.

    Although, for work, I still resort back to Debian or Ubuntu when it comes to collaborating with existing FOSS communities around robotic software or medical imaging, as those respective domains are heavily ingrained/invested into the Debian release and package distribution.

    So it's been a challenge to migrate anything other than my personal computing to NixOS. However I do appreciate the easy access to latest version releases of packages, kernels, and drivers. Being able to patch and document the idiosyncrasies of my hardware using declarative configs and revision control has been so helpful and solving a bug once and never forgetting how to reproduce the fix later on.

    Another benefit is being able to explore public repositories for examples of how other users may be installing the same types of modules or software features I'm looking to setup, or solve a similar issue. It's one thing to read the stack overflow answer about how to edit an arcane etc config for an anonymous package version, but it's another to be able to read the commit history of hundreds of other nix users and PRs from nixpkgs maintainers.

    My flake config is still rather simplistic, and synchronizing two hosts between two branches. I did appreciate the reference repo linked by the author as an example for modular host and user config.

    https://github.com/jnsgruk/nixos-config

    Any suggested resources or templates on that front? I.e. structuring and modularizing NicOS flake configs for multiple hosts for overlapping and non overlapping use cases? For example, I've just gotten into how to overlay nixpkgs PRs and explore dev shells.

  • Qt Group unveils expansion plans for technology-agnostic Qt ecosystem

    Jump

  • Yeah, any details published so far have been rather vague. I like the prospect of writing my backend UI logic in a memory safe language, but that falls short of benefiting from doing so end to end.

    Supposedly Qt would be in a decent position to use their own static analysis and testing frameworks for hardening such bridge interfaces, but using a memory safe system programming language for everything would be ideal. Are there any Rust based UI projects that are looking at ISO certification to ease integration as a Software of Unknown Pedigree?

  • What's on my Home Server 2025 – NixOS Edition - YouTube

    Jump

  • I'm not the original author, even with the YouTube title being as is, but what do you mean? Perhaps relying that the desired services exist as nix packages, or that nix packages have desired defaults or exposes desired config parameters?

    There are two other nix media server config projects I can think of, but I think this approach mostly facilitates the install, but not the entire initial config setup, given that a lot of the stack's internal state is captured in databases rather than text config files. So simplifying the backup and restoration of such databases seems the next best thing to persist your stack configs with nix.

  • On top of that, it'd be nice for the Bluetooth spec to roll out a higher bitrate version of HFP, as it's common 16 kHz monaural configuration is awful when listening to multimedia while on video calls, like for remote watch parties or just listening to music or playing video games while hanging out on discord. I ended up just buying a USB to TRRS adapter with pass through Power Delivery in order to use my Android device with proper AV quality.

  • Any particular reason that those OEMs made that decision when releasing those boxes? Was that range blacklisted in firmware because of the legacy specification? I thought the spec just forebode range's public allocation, but not necessarily its internal use.

  • Have you had any luck with projectors for coding? I've only ever used them for large mob-programming sessions, like during hackathons. I feel like the low/narrow contrast of projectors makes it hard to use for dark mode, not to mention the space real estate requirements. :P
