Show HN: OverType – A Markdown WYSIWYG editor that’s just a textarea
Hi HN! I got so frustrated with modern WYSIWYG editors that I started to play around with building my own. The problem I had was simple: I wanted a low-tech way to type styled text, but I didn’t want to load a complex 500KB library, especially if I was going to initialize it dozens of […]
Does OLAP Need an ORM
TL;DR · ORMs have proven to be useful for many developers in the OLTP/transactional stack (Postgres, MySQL, etc). · OLAP/analytical databases like ClickHouse could potentially benefit from ORM abstractions. · Existing transactional ORMs probably shouldn’t be extended to OLAP due to fundamental differences in semantic meaning between OLTP and OLAP. · Moose OLAP (part of […]

Here be dragons: Preventing static damage, latchup, and metastability in the 386
I’ve been reverse-engineering the Intel 386 processor (from 1985), and I’ve come across some interesting circuits for the chip’s input/output (I/O) pins. Since these pins communicate with the outside world, they face special dangers: static electricity and latchup can destroy the chip, while metastability can cause serious malfunctions. These I/O circuits are completely different from […]

Show HN: NextDNS Adds “Bypass Age Verification”
We just shipped a new feature in NextDNS: Bypass Age Verification. More and more sites (especially adult ones) are now forcing users to upload IDs or selfies to continue. We think that’s a terrible idea: handing over government documents to random sites is a huge privacy risk. This new setting workarounds those verification flows via […]
Derivatives, Gradients, Jacobians and Hessians
This article explains how these four things fit together and shows some examples of what they are used for. Derivatives Derivatives are the most fundamental concept in calculus. If you have a function, a derivative tells you how much that function changes at each point. If we start with the function , we can calculate […]
Faster Index I/O with NVMe SSDs
The Marginalia Search index has been partially rewritten to perform much better, using new data structures designed to make better use of modern hardware. This post will cover the new design, and will also touch upon some of the unexpected and unintuitive performance characteristics of NVMe SSDs when it comes to read sizes. The index […]
BBC Micro: The Ancestor to a Device You Are Guaranteed to Own
Meet my BBC Master, plus 5 1/4″ floppy disk drive, and three-button mouse ARM-based chips are found in nearly 60 percent of the world’s mobile devices Introducing the “Beeb” – the inventors of the ARM architecture used these machines to simulate and develop chip designs. Those chips are now in every home and business. This […]
LL3M: Large Language 3D Modelers
LL3M: Large Language 3D Modelers Paper arXiv Code BibTeX University of Chicago LL3M uses a team of large language models to write Python code that creates and edits 3D assets in Blender. Given user text instructions, the agents are capable of creating expressive shapes from scratch, and realizing complex, precise geometric manipulations in code. Whereas […]
