@recursive @abraxas3d @Stormgren There are also hacker spaces with mills and CNC gear, and people there who may happy to do machining for others.

@Stormgren totally agreed, and there is simply not enough time for a normal person to do everything from scratch.

@Stormgren @recursive @abraxas3d This is where I'm at with uwaves. I built a 10 GHz amp from a kit a while back and that was a good learning experience at the next level down. One barrier is having the right lab gear for hacking on uwave circuits. It's a significant investment in older tech (or very expensive new tech), and gaining specialized knowledge to use it. Slowly but surely...

@adamjsy Actually that seems like a reasonable price. I'm seeing $140-$400 for name brands.

Troubleshooting a Tek spectrum analyzer PSU. Gonna need a bigger boat. I mean, an ESR meter.
Any recommendations on a budget ESR meter? 🤔

A new batch of Linux Security Summit stickers has arrived! These will be distributed at upcoming conferences, starting with LSS-EU in a few weeks. There's also now a "Europe" 🇪🇺 version of the sticker.

I read this while flying across the Pacific Ocean and can highly recommend. Mersini-Houghton has established, with a testable theory, how our universe arose from an energy landscape as one of many different universes, overturning millennia of entrenched thinking that our world is special.

There's a good video on this here but I definitely needed the book to understand the finer details.

It's interesting that the observed evidence for her theory is stronger than she indicates in the video -- she is incredibly humble!

@vathpela not that I know of. I think this can be run on a real quantum computer if I can figure out the right cloud magic.

Definitely living in the future here -- using AI to write code for a quantum computer.

The local electronics store (Vetco) is an Aladdin's cave of test equipment at the moment.

It could be interpreted as "to avoid starting a new interaction, do not reply", so if you did not want a new interaction, you would in fact need to reply.

@appfrosch @searls It is confusing English, and can be interpreted as the opposite of what they are trying to say.
