As long as you are using the LoRaWAN protocol (not just LoRa modulation), encryption is not optional. It's built into the link layer of LoRaWAN, and a device cannot join a network …

Interesting concept for a project... From what I have seen in the industry, it seems like this is something every organization ends up developing at least one custom tool for. EDA …

This is an awesome write up! I have one of these scopes, with exactly this issue after a long period in storage. When I was looking into it a few years ago the failure mode was kno…

I don't understand why fuzzing hardware is being presented as a new thing here... In silicon validation, constrained random testing has been the standard methodology for at least 1…

https://www.prbs23.com/blog/ Started a couple years ago, but I don't have as much time to write as I'd like. The majority of topics relate to ASIC design and verification, since th…

I rewrote the UI for an off the shelf WiFi digital photo frame so that it shows the latest raw images sent back from the Perseverance Mars rover. https://prbs23.com/blog/posts/pict…

If you are interested in more OSSI varieties like those, check out Wild Garden Seed: https://www.wildgardenseed.com The owner, the Frank Morton who was mentioned in article, is the…

Most architectures do not provide an interrupt that is generated by an integer overflow. Since this would be a significant architectural change in the hardware, it can't be simply …

I somewhat recently blogged about my process of setting up a private LoRaWAN network as well. https://prbs23.com/blog/posts/getting-started-with-a-private... LoRaWAN is definitely …

As others have said it's not the concept of DWDM that's new here. That has been around for a while. What is interesting here is that they have managed to integrate a DWDM transceiv…

> No. I won’t do that. It inhibits natural communication. Quite the opposite, it inhibits effective communication. Giving someone a one sentence summary of why you need to talk ena…

From what I have seen of both the open source and commercial EDA software, I think it would take a well funded team somewhere around 4 years of development to catch up with the cur…

You seem to have already made a judgement about IME and associated management processors by calling them backdoors. Intel doesn't put IME into their processors to be a back door, b…

I totally agree that having visual diagrams of a code base can be super helpful, especially when getting familiar with the code, or onboarding a new engineer. However I don't think…

It feels like there is a cultural difference here. If someone tells me something in a one on one or small group conversation, my default assumption is that I should not share that …

I've been following the IceStorm project for a while and it's some really impressive work. Now if only we could get a decent open source SystemVerilog simulator to go along with it…
