rguiscard··on Shapelearn Qwen 3.8 27B (13.1 GB VRAM)
I wonder the same thing for Bonsai 2. ByteShape offers 5 models from IQ2_XXS-2.56bpw (8.8GB), IQ3_XXS-2.88bpw (9.9GB), IQ3_XS-3.01bpw (10.4GB), IQ3_S-3.23bpw (11.0GB) to IQ4_XS-3.84bpw (13.1GB). Their benchmarks show gradual improvement with size and users can pick one to fit theirs need. Bonsai-2-27B now is about 8.6GB. It might be good to have a quaternary version around 10-11GB to fit a computer with 16-24GB RAM.
rguiscard··on Biohub releases a world model of protein biology
A similar work is Foundry (https://github.com/RosettaCommons/foundry). While both of them are good, the main issue is that it is not accurate enough at atom level. There are good chances that predicted or designed active site is slightly different from the real structure solved by X-ray, NMR or cryo-electronic microscopy. A side-chain or two may turn the other way so that it changes how the interaction is interpreted. So the tools are good and convenient now. But the design or prediction is often hit-and-miss.

I think the point is that if the president of USA issued a few executive orders or have laws passed, he can legally take whatever he wants.

Not that I agree with that. It just seems to be the reality.

rguiscard··on China claims 3D hybrid bonding techniques for 120 TFLOPS of power
Original title is "China claims domestically-designed 14nm logic chips can rival 4nm Nvidia silicon — architecture leverages 3D hybrid bonding techniques for claimed 120 TFLOPS of power".

And the key conclusion is "14nm logic bonded directly to 18nm DRAM to drastically increase memory bandwidth and reduce compute latency."

I cannot tell it is real or not.

rguiscard··on Trade with China Is Becoming a One-Way Street
It reminds me the “First Opium War”[1] that “Qing dynasty of China did have a favorable balance of trade, primarily exporting goods like tea and silk and importing very little from Britain” (summarized by ChatGTP).

"In the U.S., migrants seeking asylum typically receive no federal aid, but they are permitted to work once they submit their applications. In Germany, they aren’t generally allowed to work until they are officially deemed refugees, which can take months or even years. But they are entitled to benefits worth as much as hundreds or thousands of euros a month..."

rguiscard··on Show HN: A note-keeping system on top of Fossil SCM
OP is here. First, thanks for all the comments. I am not aware that Fossil supports CGI and it open a new opportunity.

An important reason to use files instead of tickets or wiki is that not all my notes are in plaintext format. I unfortunately have many document in Office format. Therefore, I prefer not to use a system which solely supports text files. I need a system which can keep all the files while allow files to be opened by its application. Any system which do not have a local copy will not work well for me. Fossil does this well: it has a local copy so that files can be opened locally, it can sync to remote site, and text files can be read easily through web interface.

Another reason is that Fossil is local-first. I have written many versions of note keeping system in Rails. It is easy to start with and can be accessed easily. But migrating codes and database is not easy for someone who codes as a hobby. Keeping files in Fossil and synchronizing to other devices is just as easy as zipping all files and unzipping in another device. It is like rsync plus a web server in some sense. So instead of keeping a centralized database and maintaining it, Fossil allows me to work on files and I don’t need to worry about hosting and upgrading a database.

Of course all my comments are highly opinionated and are probably not applicable to others. It is just a demo and I appreciate all the comments. I choose Fossil because I happen to know it. I heard Hg, but never use it. So I cannot comment on the pros and cons.

The title is slightly misleading. Swimming pools are not hidden. They are undeclared for tax purpose. AI finds these pools from aerial images so that they can be taxed along with the houses.
