The result of those many months of work is this first video in a series on time and timekeeping with a Raspberry Pi time server (called 'Time Pi'), and that video is out this morning! Watch it here: https://www.youtube.com/watch?v=zT71UvUxhjU

I was honored to be visited by John Clark (Masterclock's CEO) and Dr. Demetrios Matsakis, former Chief Scientist at the US Naval Observatory, a physicist who contributed much to our understanding of time (and it's measurement). We spoke at length about DIY timing solutions!

In that second picture is my 'Time Pi', a project I've been working on for over a year which runs a Raspberry Pi as a Stratum 1 NTP/PTP server with a timing-specific GPS module from u-blox. More details on my blog: https://www.jeffgeerling.com/blog/2025/diy-ptp-grandmaster-clock-raspberry-pi

For the past few months, people have been asking me about these two clocks that keep showing up in my videos—one in my rack, another at my desk.

Both are PoE-powered NTP clocks from a local company called Masterclock 🧵

For illustrative purposes, re: Bosch requiring WiFi connection + app to use certain features like rinse or eco mode.

My old GE dishwasher broke (completely dead, tried many ways to reset, was dying for months though...).

Bought a new Bosch 500 (highest not-zillion-dollar model I could get over weekend).

Installed, went to mess with some settings, then saw:

"this setting requires the HomeConnect app"

Oh. Okay, so like Bluetooth or NFC or something?

Nope. They want me to connect my _dishwasher_ to WiFi to configure a number of settings on it! Ugh. No way, no how.

@dipolecat indeed, I hate shorteners for that very reason. (Ironic on a post relating to infosec!)

Because if the length of the URL it wouldn't fit on Twitter and I think bsky. Since I often post across 6+ sites, I don't always customize the messages for each.

@klopf I still use X, Bsky, Threads, Insta, LinkedIn, Mastodon, Facebook, and my good ol blog, because that's where viewers are.

Despite rumors to the contrary and despite Elon's best efforts to trash it, X is still a huge community, especially in the maker and electronics crowd.

Even though the scammers are getting pretty clever, you'd think these unicode-fooling names could still be detected by Google, what with all their fancy Gemini AI...

Targeted phishing is only going to get worse (re: my GitHub issue last week: https://x.com/geerlingguy/status/1901313223015518250 )

So I've been getting at least 2-4 of these emails _every day_ for a couple weeks now... they are from YouTube, and they always come from a channel named "YouTube Creators".

Except the channel name is actually not that, it just looks like that: https://tinyurl.com/2cs63xk4

Happy Jellyfin user here! ;) https://www.jeffgeerling.com/blog/2022/why-i-use-jellyfin-my-home-media-library

@nitpicking @wes If anything I'd do something like PeerTube, but it's just not a viable alternative in terms of keeping any form of community aspect + enough monetary compensation for the video content to keep me afloat.

There are few things that grate on me more than people copying and pasting straight ChatGPT generated comments on blogs, videos, etc.

At least do the minimum effort of typing out your own thought based on their summary and your own brain.

Just finished uploading subtitle tracks for all my videos on Floatplane!

The UX is a little annoying to add them, but it's only two more clicks than YouTube. Well worth it to add captions!

@kc8sbv all the videos are still on YouTube, floatplane is only my out in case YouTube decides to nuke my channel via AI robots

I got The Witcher 3 running on RISC-V Linux... just don't look too closely at the fps!

OpenAI's nightmare: DeepSeek R1 on a Raspberry Pi 5 ;)

The irony that 'Open'AI is so closed that a Chinese open model can come in and deflate the OpenAI bubble in less than a week...
