Dave Stokes: Ever Run Into A PostgreSQL Query That You Can Figure Out What It Does??

Ever have a query 'tossed over the fence' that you find incomprehensible but still have to support it? A few years ago, you would have needed to triage the query. Obfuscated queries can be tough to decipher.  Sometimes, the query is due to someone or an ORM being clever. Many times the query is touch to read because the DBeaver recently added its AI Chat to the free, open-source DBeaver Community Edition. And you will find it very at determining what a query does. Let's start with a simple que

Built a terminal-first tool for working with HTTP APIs

Been working on a small side project for the last few months called reqsh. The idea started because I was constantly jumping between curl commands, Postman, editing headers, copying tokens, changing base URLs... it just felt more annoying than it should. So I ended up building a terminal-first HTTP REPL where you stay in one interactive session. You can save base URLs, keep headers around, use variables, organize requests and just experiment without rewriting the same command over and over. It's

What Every Python Developer Should Know About the CPython ABI

Better tools made Copilot code review worse. Here&#8217;s how we actually improved it.

Give an agent better tools and it should do better work. That’s the instinct, anyway. When you open a pull request, Copilot code review reads the diff and explores the surrounding code to find the problems that matter before they ship. To do that, it used its own code exploration tools. So when we swapped in the better-maintained, shared tools that power the Copilot CLI, grep, glob, and view, we expected a clean upgrade. Instead, in our benchmarks, we found that the cost of reviews was h

Go-flavored concurrency in C

Go's concurrency is one of the main reasons people like the language. You write go f(), send values through channels, and the runtime scheduler runs thousands of goroutines on just a few OS threads. It feels effortless. None of that machinery exists in C. Which made me wonder: how close can you get to Go's concurrency model using only POSIX threads? Obviously, native OS threads can't match the efficiency of lightweight goroutines, but what is the actual cost, when does it become a problem, and i

A full (slow) solution to the Billion Row Challenge

We've been picking off small sub-tasks of the Billion Row Challenge, which asks us to summarise a large amount of data as quickly as we can. This time we complete the whole challenge, but in a slow way, to make sure we understand it. In future videos we will attack the last remaining sub-tasks, which concern how to collect together the information (probably in a hashmap) and print a summary.

Does anyone else end up learning more from debugging than from tutorials?

I'm still pretty new to Rust, and one thing I've noticed is that I often learn way more after spending an hour fighting a compiler error than I do from watching a tutorial. At first it's frustrating, but once I finally understand why Rust was complaining, the concept tends to stick. Borrowing, lifetimes, ownership—none of them really clicked until I had to debug real code. Is that how most people learned Rust, or did you have a different approach that made things click sooner? submitted by

Limits of Uniform Certification in the Standard Turing Model -- Semantic Invariants and Admissible Methods

arXiv:2607.07723v1 Announce Type: new Abstract: This paper does not address the mathematical truth of P versus NP. Instead, it identifies a structural limitation of uniform proof-generation methods in the standard Turing model. The observation is model-theoretic: it concerns the interaction between semantic invariants and syntactic verification, not the provability of complexity statements. We formalise an admissible method as a generator-verifier pair that produces, for each program, a finite

ReCoLoRA: Spectrum-Aware Recursive Consolidation for Continual LLM Fine-Tuning

arXiv:2607.07719v1 Announce Type: new Abstract: Parameter-efficient fine-tuning adapts a large language model to one task cheaply, but across a task sequence LoRA-style methods keep stacking low-rank updates on the same frozen weight, so each new task tends to overwrite the previous ones.

Specification-driven composition for flexible data workflows

Specification-driven composition addresses a common scalability bottleneck in data pipelines. Data pipelines often start as simple scripts, but as they grow, you duplicate transformation logic and small changes cascade across multiple workflows. Copying and modifying data transformation logic across scripts leads to workflows that become difficult to manage at scale. Tracking what each pipeline does becomes harder because workflow intent is embedded in code. This lack of visibility complicates g

Data Stitching

If you collect some data with respect to a specific context, when there are significant changes in that context, the original data no longer fits seamlessly with any newly collected data.One way to handle this is to change all of the old data, updating it to the new changes. This works, but it could take quite a while in production and can be extremely risky. A change in massive data can take days or even weeks to run. A small mistake could effectively destroy the old data. The other way to han
