This teardown and commentary remains a favorite of mine, really worth reading through: https://blog.bolt.io/juicero/

Originally it said: --- The issue has been identified as a DNSSEC signing problem at DENIC, the organization responsible for the .DE top-level domain. Cloudflare has temporarily di…

Exactly this. Many modern PHYs also integrate 802.3az (energy-efficient ethernet, a subset of Green Ethernet) but it's not super common. I also finally found this old page of using…

The original paper proposing the technology is actually very good (and surprisingly still online!): https://www.amd.com/content/dam/amd/en/documents/archived-te...

The Tailscale client (non-GUI) is open source: https://github.com/tailscale/tailscale And they collaborate with Headscale to provide an open-source coordination server (with, unsur…

I've been thinking about that illustration of Smaug for nearly 40 years and I never knew where it came from (I didn't recall it was from a Tolkien-related thing, but I remember it …

This someone jogged a memory of an all-time favorite line from a 2005 laptop review (well, more of a rant than a review): https://web.archive.org/web/20090709072628/https://arstech…

The ratio of the length of the diagonal of a pentagon to one of its sides is the golden ratio -- easiest visualization is with similar triangles. Draw a regular pentagon (sides of …

In this lovely paper: https://tom7.org/chess/longest.pdf The author points out that: "This rule only applied to games started after its introduction, so it is possible that some pr…

This comment has, I think, made me more sad than anything I've ever read on HN before. David is one of the most thoughtful, critical, and valuable voices on the topic of digital ar…

That's my understanding as well, but I still wouldn't disassemble a 1960s microwave without protection (I have assisted in the dismantling of a couple microwave communications devi…

As a second regards the microwave, depending on the age, please be extremely careful about the magnetron the insulators on which could contain beryllium oxide, which can kill you. …

There are approaches to real-time ethernet (some industry implementations like profinet or ethercat, 802.1as from IEEE) but support is spotty and it requires specialized gear to be…

A long time ago I used one of these HDMI-CEC-to-USB/serial bridges: https://web.archive.org/web/20110219131237/http://rainshadow... (I'd gotten a large LG monitor instead of a flat…

We'll be celebrating this at the Internet Archive! As a lead-up, we're again hosting our Public Domain Film Remix Contest: https://blog.archive.org/2025/12/01/2026-public-domain-da…

If you have the opportunity, I would strongly recommend visiting the vintageTEK Museum whose site this is on (it's just outside Portland) sometime. Many of the folks working there …

Among the many reasons that stretch of 26 is dangerous is that the approach from Portland is essentially a freeway from Gresham through Sandy, and then turns into a rural highway u…

I'm maybe too close to the problem to evaluate well (studied foundational math) but I know that Lawvere and Schanuel's book "Conceptual Mathematics" has been fairly well-regarded a…

It's kinda gimmicky but I found this thing on clearance at a local hardware store and it works fairly well (gets most weeds out without me having to bend over, which is nice): http…

I had the same concerns awhile back and ending up running a slightly modified version of https://github.com/wiedehopf/mlat-client -- not quite as simple as an http push, but much s…

Lovely, thank you! Looking forward to checking it out.

Do you happen to recall which version? I've picked up a couple kid's books/playsets but mine is ready for a chapter-book type version soon. FWIW my favorite reading copy is the UC …

Hi, I run the datacenter/infrastructure team at the Internet Archive! We would love to see you at our various events this fall but if paying for the ticket is difficult for you, pl…

There's not a huge amount of info I've seen on the specifics of Starlink's LISL setup, but there are a couple interesting bits in here: https://www.pcmag.com/news/starlinks-laser-s…
