A spectacular view of our Moon as photographed by South Korea’s KPLO lunar orbiter.  Image: KARI Newly forged KASA aims to land on Luna At long last, South Korea formed its space agency called the Korea Aerospace Administration (KASA) to consolidate and/or coordinate the country’s various space activities—which span space science research, rocket and spacecraft technology development, and private space activities. So far, each of these core activities tended to have distinct organizati...

Copying data in software is cheap, but it is not at all free. As you start optimizing your code, you might find that copies become a performance bottleneck. Let me be clear that copies really are cheap. It is often more performant to copy that data than to track the same memory across different threads. The case I am interested in is when copies turn a trivial operation into one that is relatively expensive. Recently, the fast JavaScript runtime (Bun) optimized its base64 decoding routines.B...

Hello, Grab your best lube, because it's time to talk about fluids! Reaching the breaking point It is no secret that Factorio's fluid system is unpredictable, unintuitive, and at times, frustrating. Pipe throughput decreases over distance at an inconsistent rate, so the only way to reliably know how much fluid you can push through a pipe is to reference a table on the wiki . Furthermore, the throughput can vary depending on the order that the pipes were built. It is not a fun system ...

Previous parts of this series: Physical Properties #1 Physical Properties #2 Physical Properties #3 Relational query planning makes a distinction between "logical properties" and "physical properties." Logical properties are the attributes of a result set that are essential to it being considered correct, such as "which rows are present." Physical properties are those that are artifacts of the way we computed a result set, like the order of the rows in a stream. One way I've define...

I maintain a GitHub Action called check-for-changed-files . For the purpose of this blog post what the action does isn't important, but the fact that I authored it originally in TypeScript is. See, one day I tried to update the NPM dependencies. Unfortunately, that update broke everything in a really bad way due to how the libraries I used to access PR details changed and howthe TypeScript types changed. I had also gotten tired of updating the NPM dependencies for security concerns I didn...

Retrieval Augmented Generation (RAG) is a technique for adding extra "knowledge" to systems built on LLMs, allowing them to answer questions against custom information not included in their training data. A common way to implement this is to take a question from a user, translate that into a set of search queries, run those against a search engine and then feed the results back into the LLM to generate an answer. I built a basic version of this pattern against the brand new Claude 3.5 Sonnet ...

Yes I did. Yes I did.

I've been harbouring some thoughts about the state of data breaches over recent months, and I feel they've finally manifested themselves into a cohesive enough story to write down. Parts of this story relate to very sensitive incidents and parts to criminal activity, not just on behalf of those executing data breaches but also very likely on behalf of some organisations handling them. As such, I'm not going to refer to any specific incidents or company names, rather I'm going to speak more gener...

< Cadey > This is a clip from a longer stream VOD. This has been mildly edited for clarity and brevity. The full stream VOD is available on my website .

To use the Montreal subway (the Métro), you tap a paper ticket against the turnstile and it opens. The ticket works through a system called NFC, but what's happening internally? How does the ticket work without a battery? How does it communicate with the turnstile? And how can it be so cheap that you can throw the ticket away after one use? To answer these questions, I opened up a ticket and examined the tiny chip inside. The image below shows the chip inside the ticket, highly magnified. The...
