1e1a··on Can you build a recognizable World Map in under 500 bytes?
I feel like this challenge would be a lot more interesting if the size of complete code needed to output the map were counted.
1e1a··on Dissecting Apple's Sparse Image Format (ASIF)
Additionally, while I don't know much about APFS, I don't think it would be beneficial to point the extracted app to blocks that are also part of the dmg file, i.e. some copying has to happen anyway.
1e1a··on IP Crawl: Living atlas of open webcams discovered on the public internet
Many consumer routers allow any connected device to configure port forwarding using UPnP. If you want, you can play around with this using a client such as miniupnpc's example client.
1e1a··on Framework's 10G Ethernet module exposes USB-C's complexity
I wonder why they went with USB-C for expansion slots instead of PCIe
1e1a··on 45°C cooling design cuts data center water use to near zero
Yes, they are using evaporative cooling.
1e1a··on OpenAI unveils its first custom chip, built by Broadcom
you can try it out here: https://chatjimmy.ai/
1e1a··on Optocam Zero: a Pi Zero based digital camera made using off the shelf components
The electronics alone are at least €100
1e1a··on Show HN: I am building a map of people who lived in the Roman Empire
Ah, I was referring to the zoom-level-dependent clustering, which I find makes it hard to see the distribution of points when zoomed out all the way. There's still quite a bit of detail even with many of the points sharing the same location.
1e1a··on Tesla allegedly in autopilot mode crashes into Texas house, woman killed
Why do news outlets so often use the phrase "high rate of speed"? Speed isn't a discrete event, it can't really have a rate, unless it is a rate of change, in which case they would be referring to acceleration.
1e1a··on Show HN: Make PDFs look scanned (CLI or in the browser via WASM)
MacOS does this as well in Preview.
1e1a··on Firewood Splitting Simulator
This is fun and looks amazing, however there seems to be quite a bit of texture in the out of focus blur. There's also a lot of aliasing on the grass. Also, I think the camera shake could do with a very slight delay after the axe hits, and maybe a slightly slower decay curve.
1e1a··on Show HN: I am building a map of people who lived in the Roman Empire
This is very cool, but unfortunately it's hard to get a sense of what the actual spatial distribution of people looks like when nearby nodes are grouped into larger dots that obscure the local structure.
1e1a··on The IsUpMap lets you check the status of over 100 major sites at once
Would be interesting if sites could be grouped based on what services they rely on, or just grouped based on which have correlated downtime.
1e1a··on Gmail thinks I'm stupid, so I left
Apple does this as well with MacOS update notifications

  Upgrade to MacOS Tahoe?
  
  [ ] Yes
  [ ] Remind me later
1e1a··on Show HN: Hallucinate – Massively Multiplayer Online Rave
I made a player motion heat map from ~5 hours of data: https://i.imgur.com/7lDuJI6.png
1e1a··on I'm Getting into Mesh Networks (Meshtastic, MeshCore, and Reticulum)
Radio Transmission Optimization
1e1a··on YouTube to automatically label AI-generated videos
Even worse, sometimes it dubs ads, where there's no way to switch the audio track and no way to see if it's being dubbed. This also makes it look like the dubbed audio is the original audio from the ad, which makes the advertiser look terrible.
1e1a··on Warm up your MacBook (2019)
Another (more useful) option is to render an animation in Blender, or run a local LLM.
1e1a··on Hacker News front page as a site
What about a global toggle to switch between the AI summaries and article snippets?
1e1a··on Apple Is Quietly Building the Most Profitable AI Toll Booth
Merely 30% of this page's area is made up by the actual content I'm trying to read.
1e1a··on Distributing Mac software is increasing my cortisol levels
I believe that at least app-store apps are already ran in some sort of sandbox.
1e1a··on Serving a website on a Raspberry Pi Zero running in RAM
One could record from the microphone and then transmit via RF side channel.
1e1a··on Debunking the CIA's “magic” heartbeat sensor [video]
If they can detect the faint signal of a heartbeat from so far away, why not instead deliberately transmit a weak, wider-bandwidth pseudorandom magnetic signal? Such a signal would be even harder to detect than a heartbeat without prior knowledge, yet easier to identify and track using a matched filter.
1e1a··on Apple ignores DMA interoperability requests and contradicts own documentation
I too was confused
1e1a··on Filing the corners off my MacBooks
The edges of the air intake slits are much sharper.
1e1a··on Show HN: I made a YouTube search form with advanced filters
I looked into youtube's search filters recently, and the length range option is stored as an enum (stored as base64-encoded protobuf in the sp query parameter), so it doesn't look like it's possible to set to specific values.
1e1a··on Show HN: OsintRadar – Curated directory for osint tools
Some of the descriptions are a little vague, eg. "GeoPlaner provides capabilities for geospatial analysis, map verification, and location intelligence."
1e1a··on ESP32-S31: Dual-Core RISC-V SoC with Wi-Fi 6, Bluetooth 5.4, and Advanced HMI
For reference, the 4-bit PSRAM interface on the ESP32-S3 normally runs at 80 MHz (maximum 120 MHz) and shares bandwidth with the external flash.

I wonder if it will be possible to (ab)use the faster PSRAM interface on the ESP32-S31 as a general purpose 8-bit parallel interface, eg. for ADCs...

1e1a··on I decompiled the White House's new app
This website is quite GPU intensive when scrolling.
1e1a··on Automatically generate all 3D print files for organizing a drawer
It looks like that's just a generic error message. For me, this websocket message is received when the error appears:

    {"error":true,"body":"Your credit balance is too low to access the Anthropic API. Please go to Plans & Billing to upgrade or purchase credits.","done":false,"id":"XXXXXXXX","type":"cf_agent_use_chat_response"}
