Just ran a successful non-interactive build and test cycle of ngscopeclient in a Debian VM with a PCIe passthrough GPU.
Just start the VM from the snapshot, paste a handful of shell commands into a SSH session, and I get this.
Still need to work out how to actually spawn the VM, specify the hash I want to build, shut it down and revert when done, etc.
Took only three and a half minutes on this instance (16GB RAM, 16 vCPU, GTX 1630) which is pretty decent considering there w…

Well I think I just found and root caused accidental O(n^2) behavior in a piece of commercial software that was turning what should have a been a few-second operation into six minutes.
It's sooo nice working with cooperative vendors. Finding and root causing the bug took me only a couple of minutes in VTune thanks to the vendor sharing a non-stripped binary with me to help me troubleshoot.

Das IOC ist ähnlich korrupt wie die FIFA und mindestens genau so willfähig gegenüber Diktaturen und tief im Enddarm Trumps. Daher mein Respekt für Sportler*innen und auch Fans, die für Menschenrechte und Demokratie die Zähne auseinander kriegen - und dafür, wie der skandalösen Ausschluss des ukrainischen Skeleton-Fahrers Wladislaw Heraskewytsch zeigt, einiges riskieren.

OK, I think I'm at the point that I need to spend a few minutes narrating a demo video of this. Screenshots don't do it justice.
100baseT1 decode, eye measurements, and constellation - including S-parameter de-embedding of the directional coupler on the test fixture - running in real time on a ThunderScope.

Welp. That was a long night.
Good news: my last box on Debian Bookworm has been updated, I'm now 100% Trixie, both bare metal and VMs.
And the prodigal scope is back from the LeCroy service center after what feels like several months of downtime between waiting for friends to help me rack/unrack the 70 pound boat anchor and shipping back and forth.
Turns out there were multiple failed internal power supplies, both on the acquisition board and the top level system PSU, p…

Is there a name for a number representation system where you store an exponent for an entire dataset, then a mantissa for each value?
So you might have e.g. units=Hz, scale factor=1e6, values=A....Z (measured in MHz)

Thinking about future release plans for ngscopeclient.
There have been massive performance improvements and some significant bug fixes since v0.1.1 and the ThunderScope dev edition units are going to manufacture so we'll be getting a lot of additional users in ~2 months.
But there's also a lot of ongoing backend refactoring and changes to filter graph blocks that won't be strictly backwards compatible (old filter graphs will need updating) and while I freely break sof…
