I received a couple BliKVM units recently, and since I don't have as much of a need (my only 'remote' PC is about 2' away from my desk...), I brought them to my Dad's radio station, and we set it up in their main on-air PC so operators could access the PC and fix problems at home, instead of driving in!

I started submitting my blog posts to Hacker News around 2016, but only ones I thought relevant to the HN community.

Until 2020, I would do this about once a week, and most submissions would fall off /newest within an hour, never to be seen again. But a problem arose (well, 'problem' depends on your perspective 😉): over time, more of my posts started hitting HN's front page.

HN is an interesting communityâ

tl;dr : This website is currently being hosted off-grid, on a cluster of Raspberry Pis, via 4G LTE—or at some points through the same tunnel via WiFi if signal strength gets too low. Here's the GitHub repo for the project .

Note : The website was down for a few hours this morning, as shortly after this post I started getting a 40-50 Mbps flood of POST requests (over 6 million in a 30 minute time frame).

The internal WiFi module on the Compute Module 4 (that's the bit under the metal shield in the picture above) routes its antenna signal via software. You can route the signal to either:

1. The built-in PCB triangle antenna (this is the default).
2. The external U.FL connector (which has an external antenna plugged into it in the picture above)

To switch the signal to the U.FL connector (for example, if you're installing your CM4 in a metal box where

64-bits. More is always better, right?

Well, not exactly. And that's why it's taken years for Raspberry Pi OS to add an officially-supported 64-bit version, in addition to the 32-bit version they've had since the original Pi came out.

Since May 2020 , there's been a beta 64-bit version of Pi OS, but it wasn't intended for beginners, and was never linked from the

Today's video is about Starlink—I've had an active subscription since last February, and as it's been a year, I figured I should post an update.

The tl;dr: when I had a new roof put on late last summer, I took down 'Dishy McFlatface', but I haven't put the dish back up. I have been holding out hope I could transfer my hardware to my cousin, who lives on a farm 70 miles away, and

Yesterday André Costa emailed me about his new website, rpilocator .

It's a website to track Raspberry Pi 4 model B, Compute Module 4, Pi Zero 2 W, and Pico availability across multiple retailers in different countries.

In his own words:

This database was created out of frustration trying to locate a Raspberry Pi product in the height of the chip and supply chain shortages of 2021. I got tired of visiting multiple websites every day trying to figure out if there were any Raspberry Pi

Since I've set this up a number of times, but I just realized I've never documented it on my blog, I thought I'd finally do that.

I have a set of servers that are running on a private network. That network is connected to the Internet through a single reverse proxy / 'bastion' host.

But I still want to be able to manage the servers on the private network behind the bastion from outside.

Method 1 - Inventory vars
