Devstral | Mistral AI

mistral.ai

agentic LLM for software engineering tasks. Devstral is built under a collaboration between Mistral AI and All Hands AI 🙌, and outperforms all open-source models on SWE-Bench Verified by a large margin. We release Devstral under the Apache 2.0 license.

All Hands AI

all-hands.dev

Open Source Agents for Developers
Use AI to tackle the toil in your backlog, so you can focus on what matters: hard problems, creative challenges, and over-engineering your dotfiles

A Critical Look at MCP - Raz Blog

raz.sh

"MCP is an open protocol that standardizes how applications provide context to LLMs. Think of MCP like a USB-C port for AI applications. Just as USB-C provides a standardized way to connect your devices to various peripherals and accessories, MCP provides a standardized way to connect AI models to different data sources and tools."

Emacs Lisp

Emacs Lisp Elements by Protesilaos Stavrou is a book about the emacs lisp Programming Language.

Prot - the author - is a pretty incredible guy. He maintains a bunch of nice Emacs packages and themes.

But maybe even more remarkable: he got kicked out of his flat in Greece, couldn't afford a new place, bought a small plot of land in the mountains and started building a hut from materials he was able to afford or from things neighbours gave him. Really the bare minimum (he often sat in his hut with a jacket in winter cause it wasn't well isolated/heated)

Absolutely inspiration, all documented on his YouTube channel https://youtube.com/@protesilaos?si=MnjV7MhKtsT5RDSM -- via Hacker News

Grepping logs remains terrible - Chronicae Novis Rebus

chronicles.mad-scientist.club

look at victorialogs as an alternative to #elasticsearch

VictoriaLogs, a high performance log database. It’s not your average generic indexer like ElasticSearch and its ilk, nor is it anything like a traditional relational database. It shows some resemblance to document stores, but only on the surface. It is specifically built for logs. Structured data is indexed and tokenized. Due to tokenization, the on-disk (and thus, in-memory) data is a lot smaller, and many queries are considerably cheaper, even if performing a full scan: rather than comparing arbitrary long strings, it will compare much smaller, bounded integer tokens in most cases.

Markdown and the Slow Fade of the Formatting Fetish

ia.net

Over the years, the format used in writing apps started to change from proprietary .docx to .pages and .pdf to the innocuous syntax called Markdown. Outside the tech field, few are familiar with its name, and yet more and more people use it unknowingly.9

Today, Slack, Discord, WhatsApp, Google Chat, Teams, and Trello, among others, use Markdown syntax, at least partially. Seeing weird characters when you copy-paste from AI? That’s because ChatGPT, Claude, Gemini, DeepSeek, and others use Markdown to format their responses. GitHub, Reddit, and similar tech-oriented sites have been using their own Markdown flavors for years now.

Horseless intelligence | Ned Batchelder

nedbatchelder.com

My advice about using AI is simple: use AI as an assistant, not an expert, and use it judiciously. Some people will object, “but AI can be wrong!” Yes, and so can the internet in general, but no one now recommends avoiding online resources because they can be wrong. They recommend taking it all with a grain of salt and being careful. That’s what you should do with AI help as well.

Introduction | Pocket ID

pocket-id.org

Pocket ID is a simple OIDC provider that allows users to authenticate with their passkeys to your services.

The goal of Pocket ID is to be a simple and easy-to-use. There are other self-hosted OIDC providers like Keycloak or ORY Hydra but they are often too complex for simple use cases.

Additionally, what makes Pocket ID special is that it only supports passkey authentication, which means you don’t need a password. Some people might not like this idea at first, but I believe passkeys are the future, and once you try them, you’ll love them. For example, you can now use a physical Yubikey to sign in to all your self-hosted services easily and securely.
