SwiftUI 3D is Flat

SwiftUI 3D is Flat SwiftUI looks like it does 3D. rotation3DEffect takes an axis, an anchor, an anchorZ, and a perspective parameter. projectionEffect takes a full ProjectionTransform, and ProjectionTransform can even be initialized directly from a CATransform3D. A custom GeometryEffect hands you the view’s size and lets you return any projection matrix you can compute. Pose one view with these and it looks convincingly, beautifully three-dimensional. So build a cube. Six faces, one shared spa

Could multiple microphones/speakers be combined for faster dial up?

i was thinking about how dial up is basically your phone literally making sounds to your compute, which the computer hears and translates into data. could you design a system that used multiple phone speakers and multiple microphone pickups to simultaneously get dial-up internet info to speed it up? if so, how many phone receivers would it take to get modern internet speeds? submitted by /u/gmanflnj [link] [comments]

A distributed safety system independently converged to biological architecture, paper exploring why

I designed a distributed observer system for fleet-scale infrastructure safety in an industrial context (the implementation is proprietary, but the paper describes the convergence at structural level). Think: something that watches a large execution platform across multiple independent trust boundaries and halts everything if it detects compromise. After completing the design, I realized the architecture had independently converged to the same solutions biology uses: heartbeat liveness signaling

What is a good way to represent files semantically for vector search

I recently had an idea that is it possible to make a software service which could help me search files from my files system though context of content inside the files. So like i can search "where is the file which contained x thing" and get would a list of files that would match my question. So I don't want sear or keywords but ch by file name context. Also for all types of files like iamge, text, video, audio, code etc So I kept thinking about it and knew that the answer lied within vector sear

We Pay Engineers to Cut Our Infra Bill

One engineer at Rootly added lifecycle policies to our ECR repositories. 95% of them had no cleanup policy. Container image storage was trending from $3K to $7.6K per month. A few PRs later, we were saving roughly $44K a year. Their reward? A thumbs-up emoji in Slack.

Reciprocal Rank Fusion: the one-line algorithm behind hybrid search

If you have ever built a RAG pipeline, you have probably faced the same awkward problem: BM25 returns a list of documents with scores like 18.3, your vector index returns another list with cosine similarities between 0 and 1, and somebody on the team asks the obvious question — how do we merge these into one ranking? The naive answer (“normalize and add them up”) is wrong in interesting ways. The good answer is a sixteen-year-old paper with a one-line formula.

Learning about exploits through the safety of Incus

The last few weeks have been quite busy with vulnerabilities that affect all sort of operating systems. It’s the age of AI, and AI tools help identify yet another class of security vulnerabilities. Several of those vulnerabilities are released while the updates are not ready yet. There exist mitigations though, and it’s important to do the mitigations until the package updates are ready. We are looking into the ssh-keysign-pwn security vulnerability. Here, a unprivileged process can d...

Salvius joins moltbook

Earlier this year a new social network emerged, gaining notoriety due to its target user base: bots, or rather AI agents. The platform's name, "moltbook" originating from the AI assistant tool, Molt (formerly Clawdbot, now OpenClaw). Started by Matt Schlicht, moltbook acts as a central hub where AI agents are able to post, comment, and follow one another. Discussion topics range from AI agents sharing about what they do for their human, to complex existential and philosophical points of vie...

Why Vision-Language AI Models Can "See" Images But Fail at Basic Reasoning (And How to Fix It)

Your Multimodal Model Can See the Math Problem But Forgets How to Solve ItTL;DR — Multimodal AI models with Mixture-of-Experts architecture can read text from images perfectly but somehow fail at reasoning tasks they'd solve easily if you just typed the same text. The problem? The image distracts the routing system from activating the right "expert" neurons.What It IsPicture this: you show a vision-language model a screenshot of a math word problem. It reads every number correctly, understa...

Using OxCaml to implement type-safe reference counting between OCaml and Python

Jane Street is known for being an OCaml shop, but for years now Python has been our second major programming language, acting as the primary tool for data analysis and (especially importantly these days) machine learning. Most of our traders and researchers think and write in Python, even as the majority of our infrastructure is written in OCaml.

The engine on which it was built was designed for a single player, so how did it work as a multiplayer game? This blog will attem...

Our MongoDB TLA+ Workshop

Shortly after I joined MongoDB research, we ran a TLA+ workshop. It was a two-day ordeal. We had a 1.5 days of instruction on TLA+ and syntax, after which we tried to help people get started with modeling. People liked learning about TLA+ on the first day, but except for a person or two, we didn't get anyone onboarded with TLA+ modeling. It was too much to offload on people and ask them to level up in a short time frame.Well, two years after that first workshop, on May 11th, 2026, we ran a se...

British Bastards - Illegitimacy in the English Monarchy

The laws and customs pertaining succession to the throne in the Kingdom of England were, in normal times, simple. The eldest legitimate surviving son of the monarch automatically succeeded his father on the throne after his father's death. If the monarch did not have surviving sons but had surviving brothers, then the eldest of those would rule. The formal name for this succession method is agnatic primogeniture. But what if the King had no surviving legitimate male heirs? Then things became ...

Adapting Apple's RGB Color Monitor for Analogue & MiSTer

While the Apple IIgs could connect to a composite display, Apple released a high-quality color RGB monitor specifically designed for the IIgs. This monitor was called the Apple Color RGB Monitor, A2M6014. It was the only color monitor Apple ever released which could accept full analog RGB video signals at the standard 240p/480i resolution (using a 15.7KHz horizontal line frequency). I have recently acquired a full Apple IIgs setup, and while the IIgs needs some repair to its mainboard the mon...

ACM CAIS: Conference on AI and Agentic Systems

And yes, I promise to write a summary of our paper, "A Case for Simulation-Driven Resilience in Agent-First Data Systems" soon! To start with an overall impression of the conference: much of the work presented felt exploratory and anecdotal. Since the compound AI space is still so new, many work seemed to share on-the-ground best practices that...

Our Collective Bike Shed Moment

Writing Code vs. Shipping Code: Productivity Effects Across Generations of AI Coding Tools

Running Doom on a 20-Year-Old Snom 360 Office Phone

This post is dedicated to my ADD and getting sidetracked at every possible step. A while back, I was given several VoIP phones that were phased out at my old job, among which were two Snom 360 Business phones from 2005. My original plan was to set up an Asterisk PBX with the phones I’d collected. But then, while upgrading the firmware on one of the Snom 360s, I had a better idea. Since this phone had a screen and a keyboard … could I get Doom running on it?

Debian testing kernel update snafu

I have a few Linux machines (one Linux box at home, and a few VPS) running Debian testing (currently Forky). In the past few days, its version of Linux kernel was upgraded to 6.19.6+deb14, then a few days later upgraded again to 6.19.6+deb14+1. And that caused some problems. Usually kernel upgrades on Debian are trivial. After the new kernel is installed, grub will be updated to have both, with the newer one being the default one. Then you remote reboot the machine, and after it rebooted int...

More Fake Mastodon Signups

Instead the applications are either friendly, generic text… I value online communities that are mo...

JStack by Command String

This has been bugging me for years: you often run a JVM by a shell script wrapper, then want to jstack it to figure out what it’s doing, but can’t figure out what PID to ask for. Running jps gives remarkably unhelpful output, especially for tools like Leiningen. I wrote a hacky little Ruby script to dig into the process tree of everything matching a given pattern, find any JVMs those processes spawned, and hit the highest numbered one (presumably the last one started) with jstack. This is...

AI agent as a teaching assistant – an experiment

I have always been experimenting with how LLMs can help me learn fundamental programming concepts. As agents become more powerful, the fundamentals only increase in relevance. However, a recent study has shown how using coding agents impairs learning. The study goes on to show that the manner in which agents are used can either contribute to or impair learning. I see agents as both the problem and the antidote, and I want to learn to use them the right way. About a year back, I learnt some f...
