More progress toward a usable light mode theme in ngscopeclient.

MR-Compare: A Mixed-Reality Framework for Spatially Grounded Visual Comparison of 3D Gaussian Splatting and Mesh Reconstructions with the Physical Environment

https://arxiv.org/abs/2607.20325 https://arxiv.org/pdf/2607.20325 https://arxiv.org/html/2607.20325
arXiv:2607.20325v1 Announce Type: new
Abstract: We introduce MR-Compare, a mixed reality framework for spatially grounded visual comparison between 3D Gaussian splatting and mesh reconstructions with live video see-through (VST). Implemented on a PC-tethered Meta Quest~3, it combines a two-stage registration pipeline with a 3D Slider for cross-media comparison. We evaluated five representative desktop and mobile reconstruction workflows through a real-world benchmark with an exploratory user study ($n=30$) in two static indoor rooms. MR-Compare achieved centimetre-level translation error across all workflows. The two desktop 3DGS workflows showed the strongest overall pattern, with 3DGS-MCMC yielding the lowest registration error and strongest VST-referenced visual consistency. Room-session measures indicated high perceived usability and low workload. We further propose an anisotropy filter, a zero-shot module that leverages Gaussian anisotropies to improve 3DGS registration in MR-Compare. A controlled Replica threshold sweep shows that moderate pruning can improve robustness and reduce residual errors. These results establish system-level feasibility in the tested setting rather than task-level effectiveness or standalone deployment. The project is available at https://github.com/changruizhu96/MR-Compare.

Turbulence Cascade in Cygnus X Revealed by Multi-point VDF Method
Junjie Huang, Yangjun Pu, Keping Qiu, Junhao Liu, Yingxi Li, Mengke Zhao
https://arxiv.org/abs/2609.08894 https://arxiv.org/pdf/2609.08894 https://arxiv.org/html/2609.08894

Abstract: Turbulence plays a crucial role in regulating star formation activities within molecular clouds, yet few methods can directly reveal its properties and underlying processes. We use molecular line data from the Nobeyama 45m Cygnus X CO Survey to study the turbulence properties and their relationships with star-forming activities and/or other non-thermal motions. In this work, we apply the multi-point velocity dispersion function (VDF), rather than direct linewidth measurements, to investigate the non-thermal properties of molecular cloud motions. We filter out the large-scale ordered structure and isolate a relatively small-scale turbulence component. Through the Friends In Velocity (FIVe) algorithm, we identify 10 substructures of the clouds and derive the turbulent properties of each cloud using the VDF method. We find that both the cloud-complex regions and the 10 velocity substructures exhibit turbulence correlation lengths of $\sim 2$--5 pc. This plateau scale suggests a parsec-scale turbulence correlation or driving scale in Cygnus X. Below this scale, the rising VDFs trace the velocity scaling of the turbulent cascade, whereas larger-scale VDF variations likely reflect cloud-scale motions. The comparison between cloud complexes and substructures further suggests that, in observational data, the VDF may constrain the turbulence correlation scale more robustly than the turbulence velocity dispersion.

I wanted local news for Wassenaar, but without press releases pretending to be journalism, political parties' own opinions dressed up as reporting, and definitely without gambling ads. So I built my own aggregator.The idea is simple enough: pull RSS from every local source I can find, dump it in a database, filter out the garbage, read what's left. In practice the filtering turned into the whole project.Right now I'm pulling from eight feeds. The municipality's own news, Omroep West, Centraal , Wassenaarders.nl, the Police1, Wassenaar Times, a 112-incident feed, and Vrienden van Wassenaar2. There's also a Google News search bolted on for regio15.nl (for pictures of accidents), since that site doesn't bother with RSS. That one runs backwards from the others: instead of a blacklist of things to exclude, it needs a whitelist of every street name in Wassenaar.Local news has a lot of overlap, and that turned out to be its own little problem. A fire, a crash, a stabbing — the same incident shows up on Omroep West, Centraal , Wassenaarders.nl and the municipality's site within a few hours, each with its own angle and its own stock photo. Reading all four versions back to back is a waste of my time. So every article gets a story ID, and anything covering the same event shares one. The August fire near Wassenaarse Slag is a good example: the municipality's evacuation notice, Omroep West's first report, Centraal 's follow-up and Wassenaarders.nl's colour piece all fold into a single thread. I read it once instead of four times with diminishing returns each pass.
The municipality's own feed, for what it's worth, is fine — road closures, permit notices, the odd royal decoration. Boring in exactly the way a municipal feed should be. The actual problem is political parties. Wassenaarders.nl in particular runs a fair amount of content that reads like it came straight out of the VVD's press office: opinion with the "opinion" part quietly removed, no facts, never a critical word. Similar stuff turns up on other sites too, from groups clearly attached to a party. None of it belongs in a news feed, because it isn't news, it's a party talking about itself.And then, separately, there's the gambling ads. At some point the person running Wassenaarders.nl started slipping in LLM-written ads for online casinos. Tacky doesn't cover it, that's close to unethical, and it has no business anywhere near something calling itself local news.Both problems land on the same site, which is why its exclude list dwarfs everyone else's combined, and keeps growing. The real reason it's such a pain is that the guy doesn't use metadata at all — no categories, no tags, nothing structured to filter on. Every other feed gives me some kind of handle beyond raw text. This one just gives me a title and a blob, so I'm stuck excluding it phrase by phrase as new junk appears. Death by a thousand keywords.One nice side effect of all this: both the 112-meldingen.nl feed and the police feed carry GPS coordinates and a priority code for every incident. Too good a dataset to ignore, so I'm using it to plot a risk map of incidents around Wassenaar, somewhere you can actually see where things cluster, rather than scroll a list of accident reports. Give it a few more months and I can map the most dangerous places in Wassenaar.Aggregating local news sounded like a small job. It wasn't, because most local sites simply aren't built to be aggregated: no proper feeds, no metadata, party messaging laundered as journalism, and in one case, a whole side business in AI-written gambling ads. The technical bit was the easy part. The filtering never really finishes.
Which took an incredible effort to find, only to discover het Police only posted two items in the last 3 years. ∩A weird local organisation that's quite critical of the government. ∩

I really need to build a "timing checker" filter for ngscopeclient that given a signal, optional clock, and some setup, hold, minimum pulse width, etc. constraints can verify that they're being met, or point out where a violation took place
Why is shader optimization so addictive? I have other things to do...
But it's 2AM, I'm thoroughly caffeinated, and staring at the Radeon GPU profiler reordering SSBO memory transactions for improved coalescing.
And successfully shaved about 1.7 ms off the first shader in the PAM4 edge detector (4.71 -> 2.98 ms, a 58% speedup). The overall filter went from 11.22 to 8.8 ms, a 27.5% speedup.
There's definitely still more room to tune, too.
Didn't get to see a total eclipse yet since I picked up astrophotography, but here's the annular one in 2023, as seen from Roswell, New Mexico.
Very simple setup with a professional-grade telescope solar filter film (from Baader) and a small handheld Nikon J5 mirrorless camera.
I would recommend NOT to use those cardboard eclipse glasses for photography, it's way too easy to get it wrong and ruin your camera sensor (or worse, your eyesight if you look through e.g. a DSLR and it accidentally slips).
If you don't really know what you're doing it's much better to just enjoy an event like this directly with the eclipse glasses on your face. (It's safe to look directly during totality, and totality only.)
There will be plenty of pictures!

There's still 117 pages left to go through, of which 96, at a rough count, are one-sentence descriptions with no other content. Who knows how much I'll have time to actually write, there's so much more to do.
But until the ThunderScop…

Got the ILA working with digital vector signals, long overdue for ngscopeclient.
There's a lot more work to do (most notably trigger comparators) but as long as you can provide an external trigger input in gateware this is usable for debug.
Threw together a quick protocol decoder for APB to test it out.
ngscopeclient now has a newly unbitrotted RGMII protocol decode!
We had this years ago in scopeclient but it used the old inefficient (std::vector<bool> at each sample) parallel bus data model and was commented out for ngscopeclient until we could come up with a better data model.
Now it's back, in time for v0.2.
I also had to un-bitrot this session file: it was an ancient (June 2020) dataset that predated the modern multi-instrument data model in ngscopeclient.…
Thinking about the integration flow for VIO-style devices in ngscopeclient (i.e. a bunch of multi-bit scalar digital input and output channels).
Does it make more sense to have one filter graph node per VIO with separate streams per input/output port? Or one node per input or output on the VIO?
Mission accomplished! Still a bunch of rough edges to work out, and I need to build equivalent blocks for other line codings as well as a "generic" ILA that just records waveforms.
But here's a simultaneous cross-trigger of the SERDES ILA and an analog waveform capture of the signal going into the SFP, (manually) deskewed and aligned.
Now imagine extending this to additional debug blocks within the FPGA.

These are all portable systemverilog and will run on anything, but the immediate motivation is making up for Efinix's rather lackluster debug tools.
The general concept is basically "CoreSight / ADIv5 for FPGAs". You have a generic transport (so far only UART is implemented) that provides read/write access to an internal APB bus with debug IPs hanging off it.
The debug bridge points to a ROM table …
