This week Jonathan Bennett and David Ruggles chat with Rak Siva and Steve Demchuck to talk about Nitric! That’s the Infrastructure from Code framework that makes it easy to use a cloud back-end in your code, using any of multiple providers, in multiple programming languages.
This week Jonathan Bennett and Doc Searls sit down with Mathias Buus Madsen and Paolo Ardoino of Holepunch, to talk about the Pear Runtime and the Keet serverless peer-to-peer platform. What happens when you take the technology built for BitTorrent, and apply it to a messaging app? What else does that allow you to do? And what’s the secret to keeping the service running even after the servers go down?
Are you interested in the history of beer, food science, or just a fan of gathering “um, actually” details about things? Well you’re in for a treat because FoodCult (exploring Food, Culture, and Identity in early modern Ireland) has a fantastic exhibition showcasing their recreation of beer last brewed in the sixteenth century by putting serious scientific work into it, and learning plenty in the process.
A typical historical beer of middling strength was around 5% alcohol by volume, similar to a modern-day lager.
The recipes, equipment and techniques are straight from what was used at Dublin Castle in the late 1500s. This process yielded very interesting insights about what beer back then was really like, how strong it was, and what was involved in the whole process.
Documentation from the era also provides cultural insight. Beer was often used to as payment and provided a significant amount of dietary energy. Dublin Castle, by the way, consumed some 26,000 gallons per year.
In many ways, beer from back then would be pretty familiar today, but there are differences as well. Chief among them are the ingredients.
While the ingredients themselves are unsurprising in nature, it is in fact impossible to 100% recreate the beer from 1574 for a simple reason: these ingredients no longer exist as they did back then. Nevertheless, the team did an inspired job of getting as close as possible to the historical versions of barley, oats, hops, yeast, and even the water.

This week Jonathan Bennett and Aaron Newcomb chat with Isaac Connor about Zoneminder! That’s the project that’s working to store and deliver all the bits from security cameras — but the CCTV world has changed a lot since Zoneminder first started, over 20 years ago. The project is working hard to keep up, with machine learning object detection, WebRTC, and more. Isaac talks a bit about developer burnout, and a case or two over the years where an aggressive contributor seems suspicious in retrospect. And when is the next stable version of Zoneminder coming out, anyway?
On March 8, 2014, Malaysia Airlines Flight 370 vanished. The crash site was never found, nor was the plane. It remains one of the most perplexing aviation mysteries in history. In the years since the crash, investigators have looked into everything from ocean currents to obscure radio phenomena to try and locate the plane. All have thus far failed to find the wreckage.
It was on July 2015 when a flaperon from the aircraft washed up on Réunion Island. It was the first piece of wreckage found, and it was hoped it could provide clues to the airliner’s final resting place. While it’s yet to reveal a final answer as to the aircraft’s fate, some of the ocean life living on it could help investigators need to find the plane. The picture is murky right now, but in an investigation where details are scarce, every little clue helps.
If you read the December 1970 issue of Mechanix Illustrated, you’d be treated to [Len Buckwalter]’s crystal radio build. He called out Modern Radio Labs as the supplier for parts. That company, run by [Elmer Osterhoudt], got so many inquiries that he produced a kit, the #74 crystal set. [Michael Simpson] found an unopened kit on eBay and — after a bidding war, took possession of the kit. The kit looked totally untouched. The crystal detector was still in the box, and there were period-appropriate newspaper wrappings.
The kit itself isn’t that remarkable, but it is a classic. An oatmeal box serves as a coil form. There’s a capacitor, a crystal detector, and headphones. The original cost of the parts was $7, but we imagine the eBay auction exceeded that by a large amount.
If the name [Len Buckwalter] sounds familiar, he was quite prolific in magazines like Electronics Illustrated and also wrote several books about transistors. [Michael] also shows off his innovative coil winder made from plastic cups and a coat hanger.
We’d love to find some old kits like this, although, from one way of thinking, it is almost a shame to build them after all these years. With an added audio amplifier and fiddling with the cat whisker, it sounded just fine.
What were some of the best posts on Hackaday last week? Elliot Williams and Al Williams decided there were too many to choose from, but they did take a sampling of the ones that caught their attention. This week’s picks were an eclectic mix of everything from metal casting and plasma cutters to radio astronomy and space telescope budgets. In between? Some basic circuit design, 3D printing, games, dogs, and software tools. Sound confusing? It won’t be, after you listen to this week’s podcast.
