Puts debugging is the best. In this tutorial, I’ll walk you through my workflow for debugging Rails codebases using a custom toolkit inspired by Rust. We will also discuss how to smuggle your debug tools, through even the most rigorous code review process. Why and how to puts debug Ruby code? I’ve never been a fan of (or properly learned) using debug breakpoints. While I sometimes use ruby debug , most of the time, I’m a puts debugger .....

MCP (Model Context Protocol) [1] is all the rage now. Introduced by Anthropic about four months ago, it has already been accepted as an open standard and has seen widespread adoption, including by major AI companies and prominent AI tool makers. There is even a directory [2] listing over 13,000 MCP implementations. Technically, it is a very simple API spec that facilitates RPC-like (Remote procedure call) communication between an AI..

Introduction In part 1 we took a higher level view on serialization in general and JSON in specific. In part 2 we looked at emitting JSON. In part 3, we’ll look at an issue you might encounter when consuming JSON, Zero vs NULL field values. To clarify the definition of NULL, this means the absence of value. So here is the question: Given a field in a Go struct set to its zero value, how do you know that zero value was set by the ..

As a prelude to what is to follow, I must say that while I am not a professional mathematician (I have a masters degree in theoretical physics and work in the software world), I do enjoy reading the occasional textbook or review paper, and wandering through its pages in a type of reverie, like walking through a glade looking at flowers. My wife has opinions about this - I suppose most of us who compare textbooks and theorems to forests and ....

When it comes to programming LLM tools, I've seen modes of interaction in the form of code completion, patch application, improvement suggestions, and text chat amongst others. Text chat is everywhere. In the context of text chat UX, I haven't really come across huge differentiators across offerings. That's not to say they don't exist. The landscape moves fast and there are far too many products out there for me to check out, thus my ques....

I tested Codex on real repos from day one of the research preview. It's fast but fragile — here's where it works and where it falls apart.

RST defaults to high This is an addendum to the article about Espressif’s automatic reset. In that article, we observed the effect of the RST pin on the ESP32-S2-Saola-1RI board: I skipped over this topic quickly, so I am now taking the time to explain how the RST pin manages to have a defined behavior […] The post The ESP32-S2 reset pin appeared first on Quentin Santos .

AI is rapidly transforming how we work, learn, and communicate. But as it evolves, we face new questions: What decisions should we let AI make? Who is responsible when it gets things wrong? And how do we ensure that the technology reflects – not replaces – our values and ideas? In this post, we’ll explore the ethical dimensions of artificial intelligence (AI) – and ideally, leave with more questions than answers.

Update 2025/05/17: It turns out that connecting Rigol scopes to the network can be very useful sometimes. Apparently you can connect your Rigol directly to PulseView by doing Connect to device → Rigol DS (rigol-ds). Update 2025/05/21: I also have access to a Siglent SDS 1202X-E, and while (AFAIK) PulseView can’t be connected to this … Continue reading Analyzing USB-PD negotiation with an oscilloscope (e.g. Rigol DS1202Z-E/Siglent SDS 1202..

What is the best way to record the Python dependencies for the reproducibility of your projects? What advantages will lock files provide for those projects? This week on the show, we welcome back Python Core Developer Brett Cannon to discuss his journey to bring PEP 751 and the pylock.toml file format to the community.

Some API vendors give you an API doc in a giant custom-edited PDF file. In my case it’s >1200 pages, with a “ helpful” table of contents that itself spans about 20 pages. Well, I dislike reading giant PDF docs, love writing Ruby, and there’s an awesome RubyLLM gem , and Gemini supports PDF parsing, so maybe I can just throw together a quick CLI tool that can answer questions for me? Alas, Gemini is limited to 1000 pages. E....

I like Gary Bernhardt. In fact, he might be my idol. He had original ideas and presented them very well. I learned a lot from his teachings. Watch this 2012 talk please , it is well worth it. In short, he listed several technologies that upon their release either “allowed saying new things” (capable) or “made innovations accessible for the industry” (suitable). According to him, LISP, C++, Ruby innovated while Fortran, SQL, Java standa....

In addition to including user content, Journelly entries typically bundle a few extra details like timestamp, location, and weather information, which look a little something like this: Behind the scenes, Journelly entries follow a fairly simple org structure: * [2025-04-23 Wed 13:24] @ Waterside House :PROPERTIES: :LATITUDE: 51.518714352892665 :LONGITUDE: -0.17575820941499262 :WEATHER_TEMPERATURE: 11.4°C :WEATHER_CONDITION: Mostly ....

I've been participating in the NixOS 25.05 Zero Hydra Failures event where people are encouraged to fix build failures in Nixpkgs. The website for the event is zh.fail (clever use of the fail tld!) and here's the current list of all failing packages and tests. I looked around in the website but I didn't find any way to filter failures only for Linux or architecture (x86_64/aarch64). This feature was requested when the zh.

I seem to be building a series on these ChatGPT-generated recipes. This one - spinach, egg, and cheddar fritters - I made on Mother’s Day morning. My wife enjoyed them. I enjoyed them. My kids - who are 5 and 7 - wouldn’t even try them.
