Second post in my Ruby concurrency series is up! "Your Ruby programs are always multi-threaded: Part 2". It digs into: fiber vs thread-locals, safely coordinating threads, a Github thread security issue, and how you can identify unsafe code and gems 🧵 https://lnkd.in/eVF84vvU

It's my first post on the Gusto engineering blog, and it's all about #RailsConf! https://lnkd.in/e4zCVUQ4

Last night I released my #RustLang crate steady_state="0.0.16" About it: https://lnkd.in/gq-w86k3 (give me a star) I hope to clean up docs and tests for a 1.0 release next month. Right now I am asking for feedback. #Makers #inventors #builders #programming 38

I have a question for software teams that meet ISO-27001 / SOC 2 Type II *and* who use outsourced software development with git. Do you have all your contractors sign all your policies so they can contribute to your codebase directly? Or do you have the outsourced team work in a separate git repository and then have an employee merge to the main repo? Or some other model?

I'm not sure my original post did this justice... it's not that Claude made this _image_... It didn't, I did. Claude made the GraphQL API and the ActiveRecord graph and wired it all up. The GraphQL schema _works_. It works. You can play with it here https://lnkd.in/gmyHrehf. It's just a mock schema, but it runs. It's not a rails app running it, but without _that_ much work, it could be. I'm not sure Claude could get it running on it's own, but I could. Why is this useful or interesting? It's an example of synthetic data generation. In this case, my synthetic data is a "ball of mud rails monolith." That's the scenario I got Claude to model. And it did a great job. Now I can use this toy app as a communication tool and testing ground for modularity tooling. I'm gonna get a blog post up on this soon, but I think it's impressive what Claude is capable of here. This kind of mundane fiction--world building, i guess--would have taken me _days_ to accomplish on my own...

We released a new update of our Visual Studio Code Java extension. Go try it! Bunch of new improvements and already supporting JDK 23 Early Access builds as the extension is directly leveraging javac. https://lnkd.in/g8BKsNjS #java #IDE #OpenJDK #VSCode

Ruby has way better support for parsing (and creating!) CSVs that I would've guessed! Check out the tutorial I wrote on the Honeybadger blog ⬇️ https://lnkd.in/gJCfcmss

First off Larry Diehl is one of the brightest ppl I ever had the pleasure to work with. His technical insights and experience are only matched by his pragmatic approach in building products. I've personally witnessed and experienced him doing so in complicated dense domains and his discipline, awareness, and ability to navigate complex + dense topics (e.g. type theory and formal verification) while keeping a pragmatic product development roadmap is truly astonishing. Secondly, I've had the privilege of seeing Larry build Colimit in real-time! It truly is a seamless gateway to bring reliability and thoroughness to apis backed by solid and principled fundamentals. Like it or not...everyone building APIs IS building distributed systems. However, not all of us have the time, expertise, and skills to build and test them reliably. Larry Diehl and Colimit are paving the way to bring that to the masses. It's truly a space that needs more love and attention. Hoping to bring Colimit to some of our teams in due time too! Super excited for what's to come! #formalverification #distributedsystems #apis

New documentation on using vanilla HTML/CSS/JS with Excalibur.js! In this example the menu is all vanilla HTML. https://lnkd.in/gxfPrXay This crystalizes patterns that the team uses when building games. PLUS a sample you can use and adapt to your favorite frontend framework. https://lnkd.in/g22AzRpS #gamedev #excaliburjs

Vercel is moving away from Edge! Lee Robinson discusses on twitter a Vercel's decision to revert all edge rendering back to Node.js, clarifying misconceptions and sharing insights. He explains the various uses of Vercel's Edge Network, the challenges of edge rendering for application compute, and the unexpected findings regarding performance, cost, and security. Robinson emphasizes the importance of careful naming and nuance in discussions and shares ongoing experiments with Partial Prerendering, showing promising results for faster load times. He hints at upcoming improvements in Vercel Functions. This is all about serving users faster and having better SEO. I will write in next post more about LCP (Large contentful paint) and FCP ( First contentful paint). Stay tuned #react #vercel #nextjs #SEO #UX #Frontend

Is this valid TypeScript? Why or why not? I 💖 type safety. I recently gave an engineering talk on it at Stay AI and this line of code helps explains the differences between values and types in TypeScript quite succinctly.

Editing tutorials that other people have written is, often, a fun challenge. 😄 Seriously! It is. What might not be obvious, though, is that (perhaps) the most challenging task of editing is figuring out what the author was trying to say. This can be made harder when the author is quite knowledgeable on a topic! Why? Because with knowledge often comes great passion. You have to passionate to be good at something, after all. But, that passion can take over, resulting in thoughts being jumbled up with one another, sentences half-finished, and so much more. 😥 That said, I'd happily work with an author who may have trouble expressing themselves — or be overly-enthusiastic — over one who is lazy and, in effect, expects me to co-write their tutorials. I'm not wanting to be harsh here, but my role is not to finish someone's thoughts — or to write their tutorial for them! That's their job. But, if you give your best, yet your thoughts are a little jumbled, that's okay. I'll take passion over laziness any day. If you've read this far and would like to write tutorials for the Twilio blog, then check out the Developer Voices Program: https://lnkd.in/eaRT4xGH. We're always looking for new contributors with knowledge, enthusiasm, and a great idea to teach! Otherwise, if you'd like me edit your tutorials and bring out the magic within them, get in touch and let's see if we're a good fit for one another. #technicalwriting // #writing // #developersarewriterstoo // #developers // #softwaredevelopers

I was reading through Charity Major's blog on stackoverflow this morning: https://lnkd.in/eWPc8Wwa and it covered several major issues: 1. What a good definition of a 'senior computer engineer' should be 2. How we can't train people the way many of us were trained by self-learning anymore.. there is too much information and too little time 3. Programming is an apprenticeship program like carpentry, mechanics, etc. You learn by doing over and over under the guidance of people who can help you grow. 4. Replacing junior programmers with AI is cutting off your future for little gain. 5. Replacing senior programmers with AI is going to be hard with the LLM way because you need to reason and deliberate over design choices more which LLM's do not do. There are lot of other good things in this post also.. but those are the ones which hit me.

Have you ever wondered how video game Auto-Tiling in games works? Excalibur.js contributor Justin Young is on🔥with this latest post about authoring tile maps with aesthetically pleasing tiles! The algorithm is surprisingly grokkable and low effort to implement 🤯 https://lnkd.in/gsVHwc5V #gamedev #typescript #javascript

An illuminating blog from my favorite #CMU #Database professor Andy Pavlo. Leaving the title aside, it's a best source for diving deep into the internals of #PostgreSQL #MVCC, Snapshot Isolation, how multiple row versions are stored within data pages, how queries find correct row versions, how indexes refer to the multiple row versions, vacuum/autovacuum, table bloat, index maintenance, heap-only tuple updates (HOT). https://lnkd.in/gryabzFj
