Weekly Tech - 9th March of 2025

Postgres and the power of the RAM, OpenTelemetry but for your LLMs? What about load-testing in PHP and more? Yes, there's all of that this week and more, ready?

Hi everyone, hope you're all fine?

New weekly tech freshly delivered and this week, PHP and the machine learning are the new stars under the light, small notice here, I'll be out during the week between the 24th and the 28th of March (I'll be present at SymfonyLive Paris, don't hesitate to say hi if you're around), now that we shared the small details, time to start.

Common knowledge

Let's start with the version 1.9 of Gleam and its support of Git (you should keep an eye on this project).

• Gleam 1.9 is out

---

Database

So, what's new in the database world? Well, not much except a brilliant article about using Postgres in "high available resources" (I'll keep the wording) and especially how it handle memory and resource under the hood.

• Could Postgres handle larger infrastructure? - French

---

Cloud computing

Small stop at the cloud mark to discover Infiscial, an open-source platform to manage your secrets (think Hashicorp Vault but without HashiCorp).

• Infiscial, an open-source secret management platform

---

Machine learning

So... Machine learning right? Let's start with OpenLLMetry, an "OpenTelemetry-like solution for LLMs" (good luck with this one as they're non-deterministic), you will also notice the release of Gemma 3 (the new "made-by Google" version of Gemma) and finally, a feedback about using a swarm of agents to handle tasks (I hate the word agent but that's just my POV).

• OpenLLMetry, an open-source observability library for your models

• Managing secrets in MCP servers thanks to Infiscial

• Could a swarm of agents handle complex situations better than a single one?

• Gemma 3, the latest model from Google

---

Rust / Go

Small detour at the Rust store to (re)discover an article about building a garbage collector in Rust, for Rust, I missed some technical details earlier last year so let's read it again one more time (did I said that I love Rust?).

• Building a garbage collector for Rust, in Rust

---

PHP

So, PHP, the big one, this week is all about load-testing (thanks to Volt, a "Go-bridged" library with a PHP SDK), you will also find a feedback about using Rust to "try to solve" PHP issues when it comes to handling long-running processed, last but not least, you'll find a deep-dive analysis of the PHP ecosystem and the published librairies.

• So, what could we learn by analyzing the whole PHP ecosystem?

• Could Rector and PHPStan improve Symfony projects with custom rules?

• VoltTest, a load-testing tool with a PHP SDK

• Grapheme, a library to mesure the width of unicode strings

• Could Rust solve PHP scaling issues? Well, not completely

That's all for this week, do not hesitate to like / comment if you liked this weekly tech, I'll publish the audio version next week (in french for this time again), until next week and especially Friday for the weekly tech, have a wonderful weekend and a great week.

See you on friday!
