There are two great Cloudflare-related stories published this weekend. The first is Steven Levy’s incredible story about Tim Jenkin, who created a secure communication protocol for the African National Congress to overthrow the apartheid regime in South Africa. Cloudflare’s CTO, John Graham-Cumming, later helped break past the cryptography system’s lost password, which he blogged about … Continue reading Cloudflare Stories →

Code Matters

It looks like the code that the newly announced Figma Sites is producing isn’t the best. There are some cool Figma-to-WordPress workflows; I hope Sites gets more people exploring those options.

Berkshire Hathaway Meeting

I’ve checked off a bucket list item: I’m attending a Berkshire Hathaway shareholder meeting. It’s really an event! Thousands flock to Omaha, Nebraska, for the legendary Q&A sessions with Warren Buffett and shareholder deals. They’ve made it quite the circus, with every Berkshire Hathaway company having a booth of some sort, and typically selling their … Continue reading Berkshire Hathaway Meeting →

Reflecting

I know there’s been a lot of frustration directed at me specifically. Some of it, I believe, is misplaced—but I also understand where it’s coming from. The passing of Pope Francis has deeply impacted me. While I still disagree with the Church on many issues, he was the Pope who broke the mold in so … Continue reading Reflecting →

Greatest Hits

I’ve been blogging now for approximately 8,465 days since my first post on Movable Type. My colleague Dan Luu helped me compile some of the “greatest hits” from the archives of ma.tt, perhaps some posts will stir some memories for you as well: Where Did WordCamps Come From? (2023) A look back at how Foo … Continue reading Greatest Hits →

A robotic hand with the dexterity to sign the whole ASL alphabet

Even if we ignore intelligence, humans are able to speak when other animals — even other great apes — can’t, because of our specialized and complex vocal anatomy. Similarly, ASL (American Sign Language) wouldn’t be possible without our incredible hand and finger dexterity. Like any other complex physiological system, that is difficult to recreate artificially. […] The post A robotic hand with the dexterity to sign the whole ASL alphabet appeared first on Arduino Blog.

Updated Arduino cores with ZephyrOS (beta)  

Last December we released our beta Arduino cores based on Zephyr. Today, we are excited to make another step in this beta program for Arduino cores based on Zephyr! ZephyrOS is an open-source, state-of-the-art, real-time operating system (RTOS) designed for low-power, resource-constrained devices. We are transitioning Arduino cores to ZephyrOS to ensure continued support and […] The post Updated Arduino cores with ZephyrOS (beta)   appeared first on Arduino Blog.

How to run Uptime Kuma in Docker in an IPv6-only environment

I use Uptime Kuma to check the availability of a few services that I run, with the most important one being my blog. It’s really nice. Today I wanted to set it up on a different machine to help troubleshoot and confirm some latency issues that I’ve observed, and for that purpose I picked the cheapest ARM-based Hetzner Cloud VM hosted in Helsinki, Finland. Hetzner provides a public IPv6 address for free, but you have to pay extra for an IPv4 address. I didn’t want to do that out of principle, so I went ahead and copied my Docker Compose definition over to the new server. For some reason, Uptime Kuma would start up on the new IPv6-only VM, but it was unsuccessful in making requests to my services, which support both IPv4 and IPv6. The requests would time out and show up as “Pending” in the UI, and the service logs complained about not being able to deliver e-mails about the failures. I confirmed IPv6 connectivity within the container by running docker exec -it uptime-kuma bash and running a few curl and ping commands with IPv6 flags, had no issues with those. When I added a public IPv4 address to the container, everything started working again. I fixed the issue by explicitly disabling the IPv4 network in the Docker Compose service definition, and that did the trick, Uptime Kuma made successful requests towards my services. It seems that the service defaults to IPv4 due to the internal Docker network giving it an IPv4 network to work with, and that causes issues when your machine doesn’t have any IPv4 network or public IPv4 address associated with it. Here’s an example Docker Compose file: name: uptime-kuma services: uptime-kuma: container_name: uptime-kuma networks: - uptime-kuma ports: - 3001:3001" volumes: - /path/to/your/storage:/app/data image: docker.io/louislam/uptime-kuma restart: always networks: uptime-kuma: enable_ipv6: true enable_ipv4: false That’s it! If you’re interested in different ways to set up IPv6 networking in Docker, check out this overview that I wrote a while ago.

This inexpensive adapter brings Apple Universal Control to vintage Macs

In the distant past of about two decades ago, one would need to use a KVM (Keyboard, Video, Mouse) switch to control multiple computers with the same mouse and keyboard — and even then, it would take a button press to move from one to the other. Today, Apple’s Universal Control feature lets users seamlessly […] The post This inexpensive adapter brings Apple Universal Control to vintage Macs appeared first on Arduino Blog.
