scary-size··on I turned my security cameras into an automatic bird identification system
Really nice project! Expected a visual ID system, surprised it was using audio. "Flock" would be a great name for the project...oh well!
scary-size··on Inception-style curved map for turn-by-turn directions
That surprised me too. VR is no issue for me, I can also usually stare at my phone in the car. But this site made me dizzy immediately.
scary-size··on Ask HN: What is your favorite lightweight tool or CLI utility in 2026?

scary-size··on Tech leaders say AI means less work – staff say they work up to 90 hours a week
They didn’t get a definition. Probably looked at the word „sprint“. Went: „Yep, sounds fast but only for a short period. Gotta be these 90 hour weeks once in a while. Definitely can’t be the thing these folks are doing continuously.“. Crunch would be a better fit for that.
scary-size··on Germany Records Historic 12B KWh Solar Feed-In in July 2026
Yey, we contribute 432 kWh to that. Northern Germany, small 6.3 kWp system.
scary-size··on Flint: A Visualization Language for the AI Era
Fair. How is this specific to the marketed AI integration? This could just be a unifying abstraction layer for a bunch of, in my opinion, verbose chart APIs. And then the LLM could just be the abstraction layer.

There’s this great post about „The Death Of Day Dreaming“: https://www.afterbabel.com/p/on-the-death-of-daydreaming
scary-size··on Windows 10 quietly gets one more year of support and updates
Already switched to CachyOS, haven’t booted to Windows 10 since then. Desktop gaming was my only use, everything else happens on an M1 Air.

It’s a delight, no pop ups, sell ups, Cortana and whatever else MS kept throwing at you.

scary-size··on Oracle shed about 20k roles globally in the last year
IIRC, WARN filings in NYC require to indicate whether lay-offs were due to AI. None of the filings of the past year checked that box [1]

scary-size··on Proportional-Integral-Derivative (PID) controllers
„How To Build a Thrust Vectored Model Rocket“ has a good section on this IIRC: https://www.youtube.com/watch?v=4cw9K9yuIyU
scary-size··on How many of the 170k English words do you know?
Check button hidden under the URL bar thing in safari, progress bar hidden when scrolling check button in view. In between endless whitespace.
scary-size··on The Future of Email
Have been paying for Fastmail for years. It’s actually fast and lets me use my own domain. (And doesn’t shove AI down my throat). Cash well spent.
scary-size··on AUR Packages Compromised with Infostealer and Rootkit
Installed CachyOS to replace my Win 10 installation a month ago. Not looking back! But yeah this sucks, I've mostly used Ubuntu with apt in the past. Pacman and makepkg felt a bit weird to use in the beginning.
scary-size··on Chrome is looking to permanently drop MV2 extension
I thought the AdGuard folks were looking doing just that!
scary-size··on How's Linear so fast? A technical breakdown
It's so satisfying to see all these techniques applied to a product. There's nothing really new tech-wise. Optimistic updates were shown in a lot of early React demos more than ten years ago. Bundle splitting, preloading and service workers have been around for a long time. But it does take a huge amount of rigor and determination to apply these methods in each layer.
scary-size··on Private equity bought America's essential services
Huh, that somehow reminds me of Crassus from Rome [1]

> The first ever Roman fire brigade was created by Crassus. Fires were almost a daily occurrence in Rome, and Crassus took advantage of the fact that Rome had no fire department, by creating his own brigade—500 men strong—which rushed to burning buildings at the first cry of alarm. Upon arriving at the scene, however, the firefighters did nothing while Crassus offered to buy the burning building from the distressed property owner, at a miserable price. If the owner agreed to sell the property, his men would put out the fire; if the owner refused, then they would simply let the structure burn to the ground. After buying many properties this way, he rebuilt them, and often leased the properties to their original owners or new tenants.

scary-size··on Germany Power Prices Turn Deeply Negative on Renewables Surge
I guess „it‘s complicated“. For our system, 6kWp with iMSys, the grid operator can cap the ingestion as they see fit. For systems over 7kWp, you are required to install a iMSys that allows them to cap. Systems without a iMSys must have the capability to cap to 60% (either at all times or „intelligently“ depending on your consumption). BUT if you install anything today, you most likely will install a iMSys anyway. Also export fees for 7kWp and below are a bit of a joke anyway.

IIIRC, new individual systems are already required to have the capability to wind down export based on external signals.
scary-size··on Show HN: Dull – Instagram Without Reels, YouTube Without Shorts (iOS)
Interesting perspective! Are we in the „fast fashion“ period of software now?
scary-size··on Show HN: Moji – A read-it-later app with self-organizing smart collections
Pretty cool! (I can't test it, seems unavailable in Germany).

How are you handling the text extraction with Readability.js? Does that run in a WebView in the background? I've built a similar, albeit less feature-complete, read-it later app in the past [1]. Spent most of my rewriting the core of the Postlight parser [2] in native Swift.

Anyway, cool project, and I'd probably buy this once its available.

scary-size··on Hacking an old Kindle to display bus arrival times
Real nice! Shutting down networking between refreshes definitely helps with the battery life. I also prevent mine [1] from updating between 10PM and 6AM. Nobody is looking at it anyway. If you search around on Github for Kindle dashboards, there's a lot of scripts out there with a bunch of battery life improvements (shutting down daemons, wifi etc.).

I built GTFS based public transit display on top of a Raspberry Pi Zero and a 2" e-ink display ~10 years ago [2].

scary-size··on I built Timeframe, our family e-paper dashboard
Maybe the folks at TRMNL? https://trmnl.com/
scary-size··on I built Timeframe, our family e-paper dashboard
Yep, it’s super cheap. I wrote about mine here:: https://franz.hamburg/writing/kindling-e-ink-dashboard.html
scary-size··on Avoid UUID Version 4 Primary Keys in Postgres
This reminds me about this old gist for generating Firebase-like "push IDs" [1]. Those have some nicer properties.

scary-size··on Let's put Tailscale on a jailbroken Kindle
I think they mean that even an OLED display will actively emit light. When, in contrast, the e-ink displays shown in the linked posts are unlit. That, for me, is the key advantage making the device blend in.
scary-size··on Let's put Tailscale on a jailbroken Kindle
I love just how non-intrusive an e-ink dashboard is sitting in a room. Definitely can recommend it as a base device that gets you display, wonky Linux, a battery and networking in neat little package.

Also recently showed my dashboard here: https://franz.hamburg/writing/kindling-e-ink-dashboard.html

scary-size··on SQLite as an Application File Format
Actually used it for a desktop blogging app a few years ago. It was great! I could set up a blog skeleton, send the file to a family member. They could focus on writing content and hitting deploy.

scary-size··on Ask HN: What are you working on? (September 2025)
Thanks, yes it’s obviously for a power system.
scary-size··on Ask HN: What are you working on? (September 2025)
Building a little dashboard for our solar system. Running on a mini PC in the office closest. Bun, React, DuckDB

scary-size··on Rules for creating good-looking user interfaces
For engineers doing UIs once in a while, I can recommend Refactoring UI [1]. It has a bunch of practical tips for making your life easier: Picking a color palette, font sizes, margins/padding etc.
