FMADIO is the company blog at fmad.io, writing about hardware and systems. Since 2016, 6 different Hacker News readers have linked it 6 times, most often “Recovering a Bricked SSD with JTAG and a Raspberry Pi”. It is still writing: the last post was on 2026-08-14, and you can follow it by feed.
Too few sampled comments (3) to say how often HN recommends it.?
Why HN links it
HN readers link FMADIO's blog on network line rate and on turning raw oscilloscope or SDR signal data into Ethernet frames. Comments mostly cite the posts as sources for networking and high-speed packet topics.
Summarised by Claude from a sample of 3 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
we are actually doing that now at https://fmad.io for SDR instead of raw oscilloscope ADC. SDR is about an order of magnitude less data e.g. 6GS/sec instead of 60GS/sec and Matlab as the backend instead of Python.. as its a bit faster when mining terabytes of data for that ah-ha wtf bit. Surprisingly cool going from raw IQ/analog data to ethernet frames much like the op has written.

HN discussionhttps://www.fmad.io/blog/what-is-10g-line-rate As the article calls it, the gold standard. If a device is capable of forwarding/switching packets at the smallest packet size line rate on all interfaces at the same time you don't have to think too much about its performance when designing your network. Haven't worked much with hardware for a few years but it was common that Cisco switches were not capable of this.

HN discussionI've never heard this weird qualification for the definition of "line rate" that it somehow requires minimum packet size, so I looked it up. The first three sources for a quoted big-g search all imply or directly state that it's the same as bandwidth: https://blog.ipspace.net/2009/03/line-rate-and-bit-rate.html https://www.reddit.com/r/networking/comments/4tk2to/bandwidt... https://www.fmad.io/blog-what-is-10g-line-…
