Bitcoin has fallen to ~$78K, down ~7% in 24 hours, over 12% in the past week, and down ~37% since its ATH in Oct. 2025; Ethereum dropped ~18% in the past week (Bloomberg)

Starting to look at some performance improvements for various scopehal filters as I begin the push for v0.2.
The benchmark dataset is P/N legs of 100baseTX Ethernet sampled at 500 Msps with a ThunderScope.
At 50M point memory depth, each waveform is 100 MB in size (2 channels * 8 bits * 500 Msps) and covers 100ms of real time.
The filter graph currently takes just shy of a second to run, meaning we're at 10% of real time. I want to improve on this.

Doing Gigabit Ethernet Over My British Phone Wires
Disclaimer: None of this is written by AI, I’m still a real person writing my own blog like its 1999 I finally figured out how to do Gigabit Ethernet over my existing phone wires. Powerline adapter…

The same way kids are addicted to TikTok nowadays, I was addicted to TV as a kid. In the place and time of my teenage years, that is Argentina during the 1980s, it was the times of hyperinflation and eternal crisis (which begs the question: has anything changed in forty years?) Such a tense situation also meant that there was not much content on the telly about a subject that I was definitely interested in since a young age: computers. I mean, you could barely afford food, so, understandably en…

Friends, if anybody could inform me about my home network setup problem, I'd greatly appreciate it!
Namely, I have a situation of a router (ISP's; I'm not given access to its configuration) that has a 2.5Gbit ethernet port, and two PCs that have 1Gbit ethernet cards (stock, on the motherboard).
To avoid running two ethernet cables across the room to the PCs, my idea was to get a switch and run one cable to the switch, and then two small cables from the switch to the P…

When you notice your carefully uploaded Mango sub-dir on your Codeberg is actually empty and the disk has been wiped. Obviously. Eternal n00b 😆

Another evening of filter refactoring and optimization, a few more nice performance jumps.
I've now done a first pass (remove deprecated method signatures, add explicit input location, add NVTX trace data, do easy GPU optimization if I see an obvious low effort win) on all filters A-F alphabetically plus a few later on that were priorities for one reason or other.
90 down (of which 23 were optimized and the rest just refactored), 115 to go.
Some of the remaining ones sh…
