Hi friends, it's been a minute since I shared an update here on this project.

Last time I posted about building a debug GUI in Rust with egui, and I enjoyed the experience so much that I decided to write a status bar for my tiling window manager using egui too!

There is a whole live coding video series which documents the creation of the bar, and I think in general the codebase has some useful tips on doing things with egui like loading custom fonts at runtime and enabling application-wide theming from colorschemes palettes like base16 and catppuccin.

Happy to answer any questions about the technology choices, the experience in general, rough edges etc.

I'm sure most of us have had to deal with issues reported by end users that we ourselves aren't able to reproduce

This video is an extended case study going through my thought process as I tried to track down and fix a mysterious performance regression which impacted a small subset of end users

I look at the impact of acquiring mutex locks across different threads, identifying hot paths by attaching to running processes, using state snapshot comparisons to avoid triggering hot paths unnecessarily, the memory implications of bounded vs unbounded channels, and much more

Hi friends, I develop and maintain the komorebi tiling window manager and have been posting live coding videos documenting its development for just over a year now.

I'm starting a new mini series on building a visual debugging gui tool to aid development on komorebi and especially to help with understanding some of the more esoteric edge cases and the interactions between the twm, user-defined rules and WinEvents.

I'll be building this from scratch using egui/eframe, so if you're interested in what building a non-trivial real-world immediate-mode gui and integrating with other (Rust, in this case) processes via IPC looks like, you'll probably get something out of this series.

Sharing some numbers on what people can realistically expect with GitHub Sponsors on a moderately popular project without any external / VC / corporate backing.

In this video I discuss the trade-offs of building on top of unstable reverse-engineered private APIs, why I decided against it, and compare to similar software that chose to use them.

A couple of people who aren't particularly interested in the software itself told me that this was an interesting and engaging video on general programming approaches when building applications for closed-source systems, so I thought I'd share it a bit more widely here.

tl;dr all the same caveats with self-hosted software apply; don't do anything you wouldn't do with a self hosted database or monitoring stack.

Well the actual rules โ€” who gets access to what

The rules themselves are the same public rules in the IAM docs on AWS, GCP etc., while the collections of these public rules (eg. the storage_analytics_ro example in the README) defined at the org level will likely be stored in two ways: 1) in a (presumably private) infra-as-code repo most probably using the Terraform provider or a future Pulumi provider, 2) the data store backing the service which I talk about more below.

"Who received access to what" is something that is tracked in the runtime logs and audit logs, but as this is a temporary elevated access management solution where anyone who is given access to the service can make a request that can be approved or denied, this is not the right place or tool for a general long-lived least-privilege mapping of "this rule => this person/this whole team".

where is that stored and how is it secured, to what standards?

This is largely up to the the team responsible for the implementation and maintenance, just like it would be for a self-hosted monitoring stack like Prom + Grafana or a self-hosted PostgreSQL instance; you can have your data exposed through public IPs, FQDNs and buckets with PostgreSQL or Prom + Grafana, or you can have them completely locked down and only available through a private network, and the same applies with Satounki.

Is there logging, audit, non-repudiation, tamper-proof, time-stamping etc.

Yes, yes, yes, yes and yes, though the degree of confidence in each of these depends to some degree on the competence of the people responsible for the implementation and the maintenance of the service as is the case with all things self-hosted.

If deployed in an organization which doesn't adhere to at least a basic least-privilege permissions approach, there is nothing stopping a bad internal actor with Administrator permissions wherever this is deployed from opening up the database directly and making whatever malicious changes they want.

Apologies in advance for sharing two link posts here two days in a row. Unemployment may be driving me a little nuts... ๐Ÿ˜…

I've been working on Satounki since I got laid off last month. It's the culmination of a lot of experience building similar ad-hoc internal tooling at various places throughout my professional career.

Satounki already includes:

  • AWS support
  • GCP support
  • Cloudflare support
  • Auto-generated Terraform providers from the Rust API
  • Auto-generated Typescript client wrapper from the Rust API
  • Slack bot for request notifications, approvals and rejections
  • CLI for requests, approvals and rejections
  • Dashboard for exploring policies, requests and stats

The scope of this project is pretty big and I'm looking for contributors.

The majority of the project is written in Rust, including the generated Go and TS code. The stack is pretty simple; Actix, Diesel, SQLite, Tera etc., so if you have experience with writing web apps in Rust it should feel familiar!

Even if this is a totally new stack to you, this is a great project to develop some familiarity and experience with it, especially if you can help improve the quality of the generated Go and TS code at the same time!

Thanks! Turns out I have a lot more time on my hands to be found around the internet since I got laid off last month ๐Ÿ˜…

This (Windows employing different methods to prevent users from writing programs that programmatically change application focus) has been an ongoing struggle for me for the better part of 3 years.

I finally made what feels like some significant progress this past week.

If you've ever obsessively gone deep down into a hole trying to understand and wrangle weird OS-level behaviors before, you might enjoy this video and feel a vicarious sense of victory :)

I wish I had more advice, but I'm in a similar boat, just got laid off earlier this month after being with the same company from Series A in 2018 all the way until today. I'm sending job applications and trying to get interviews, but it's hard to get past the resume screening stage, even with 8+ years of experience.

I've mainly been working in DevOps/SRE/Platform Infrastructure, but I am also an accomplished developer with a pretty thick portfolio of widely used open source projects, though it doesn't seem to matter.

There are so many applicants for every single job now that it feels hopeless, and of course every single opening wants you to waste your time on multiple asinine LeetCode gotcha questions.

If I lived somewhere with a public health system I'd love to take what money I have saved up and open a traditional middle eastern bakery, but I need to do something that will bring health coverage for myself and my family. Who knows, I might just end up working at Trader Joe's. ๐Ÿคทโ€โ™€

I got laid off this month and have a lot of time on my hands while I'm looking for new jobs ๐Ÿ˜…

I tried making a LinkTree but the website UI for editing is so janky and frustrating, and on top of that you have to go Premium for advanced theming, again in the janky UI...

I found this great Hugo theme called Lynx and built out my own links webpage like we did back in 90s on Geocities with Dreamweaver

Some folks on Mastodon and Twitter messaged me asking for a walkthrough because there are a few rough edges that are mostly related to changes between Hugo versions and the docs on the theme, so I made this end-to-end video going from project init to deployment on Cloudflare pages with analytics enabled

It's a pretty fun project and I think it can also be useful as a "portfolio links" page for people that are looking for jobs right now

Someone on another website asked me whether it makes sense to use agenix or sops-nix to encrypt secrets for NixOS configurations.

I realized that I hadn't seen a good overview article of the different approaches to secret handling in NixOS and when each one is appropriate to use, so I put down all of my knowledge and opinions in this post ๐Ÿคž

I think it's a stack that really pays off in the long run for solo projects. After a long week of work the last thing I want to do is go tracking down runtime errors (undefined is not a function, my old friend) or messing around with Docker containers and Kubernetes clusters. It also doesn't hurt that once you throw away the costly deployment abstractions, the operating expenses turn out to be a lot cheaper.

Found some time this past weekend to work on a little "passion feature" that I've been wanting to implement for a while now; sharing the technical write-up for anyone else who is interested in automating headless screenshots with these tools or with others (the knowledge is pretty transferable!)

These days I reach for chumsky pretty much any time I need to write a DSL parser.

I thought it would be an interesting exercise to take a DSL parser that I've written using chumsky and reimplement it the "old fashioned" way.

Highly recommended viewing if you'd like to learn more about the limits of reproducibility in the Docker ecosystem.

[-] LGUG2Z@lemmy.world 5 points 1 year ago

I understood your point, and while there are situations where it can be optional, in a context and scale of hundreds of developers, who mostly don't have any real docker knowledge, and who work almost exclusively on macOS, let alone enough to set up and maintain alternatives to Docker Desktop, the only practical option becomes to pay the licensing fees to enable the path of least resistance.

[-] LGUG2Z@lemmy.world 6 points 1 year ago

Lot's of (incorrect) assumptions here and generally a very poorly worded post that doesn't make any attempt to engage in good faith. These are the reasons for what I believe is my very first down-vote of a comment on Lemmy.

[-] LGUG2Z@lemmy.world 5 points 1 year ago

NixOS on WSL2 is actually my development environment of choice these days! (With my tiling window manager komorebi, of course! ๐Ÿ˜€)

[-] LGUG2Z@lemmy.world 6 points 1 year ago

I believe this is the Docker Desktop license pricing.

On an individual scale and even some smaller startup scales, things are a little bit different (you qualify for the free tier, everyone you work with is able to debug off-the-beaten-path Docker errors, knowledge about fixes is quick and easy to disseminate, etc.), but the context of this article and the thread on Mastodon that spawned it was a "unicorn" company with an engineering org comprised of hundreds of developers.

Hi!

First I'd like to clarify that I'm not "anti-container/Docker". ๐Ÿ˜…

There is a lot of discussion on this article (with my comments!) going on over at Tildes. I don't wanna copy-paste everything from there, but I'll share the first main response I gave to someone who had very similar feedback to kick-start some discussion on those points here as well:

Some high level points on the "why":

  • Reproducibility: Docker builds are not reproducible, and especially in a company with more than a handful of developers, it's nice not to have to worry about a docker build command in the on-boarding docs failing inexplicably (from the POV of the regular joe developer) from one day to the next

  • Cost: Docker licenses for most companies now cost $9/user/month (minimum of 5 seats required) - this is very steep for something that doesn't guarantee reproducibility and has poor performance to boot (see below)

  • Performance: Docker performance on macOS (and Windows), especially storage mount performance remains poor; this is even more acutely felt when working with languages like Node where the dependencies are file-count heavy. Sure, you could just issue everyone Linux laptops, but these days hiring is hard enough without shooting yourself in the foot by not providing a recent MBP to new devs by default

I think it's also worth drawing a line between containers as a local development tool and containers as a deployment artifact, as the above points don't really apply to the latter.

More and more lulls with more and more years of experience. I hit the gym more, socialize more, cook more extravagantly, take walks more often etc. The most important thing was to train myself to not give a damn when people were making stupid decisions at work that were going to bite them N months down the line during those lulls.

If I can even help one person avoid that same fate, it's worth it!
