> SFP28 modules are still very pricey SR is ~$40 and LR is ~$60, so more expensive than SFP+ modules but not out of the reach of someone who even has a capable SFP28 port.

Thanks! I did find this: https://lists.linuxfoundation.org/pipermail/iovisor-dev/2017... and some references to bpf_skb_ct_lookup/bpf_xdp_ct_lookup -- are these fully baked?

Is it possible to do stateful stuff like NAT in eBPF without having to reimplement conntrack? I think cilium does it but has to reimplement in using maps.

eFile could be free too but it's an enormous pain in the ass to even get registered as an IRS developer. IRS provides docs: https://www.irs.gov/e-file-providers/tax-year-2021-modernize... but hides them from the p

This is how it works in a lot of other countries. You get a pre-filled return and can accept it or file on your own.

A lot of the closed source boot Roms look to be SOC vendor code: they'd buy a subsystem ip from someone and have to redistribute the code for that thing but don't have the source licensed. Unlikely that will ever be cleared up sin

Full disclosure, I was an early employee and wrote the first integrations, so I'm likely not the right person to ask. https://www.particlehealth.com/ should have details.

Well, you don't end up having to query their DB directly, you can do it via standardized IHE ITI XDS/XCA over a network like CareQuality. There are startups like Particle that can do it as a SaaS.

Ehh, Epic cares about Epic. They lose their gatekeeping ability once TEFCA roles out with teeth. The P in HIPAA stands for portability, of course.

There needs to be a real Kuhnian paradigm shift IMO; it's embarrassing to have modern-day epicycles used as a fudge whenever a model breaks down vs. questioning the core assumptions of the model. There are more interesting and less imp

It's also wrong: the path must be a stationary point of the action, not minimal. In GR you maximize proper time to get geodesics.

Regular PTP is old hat as you say. ~5ns though I thought needs some real thought, and picosecond sync needs a combo of PTP + SyncE + link compensation, which is now the "high accuracy" profile. It's all fairly simple in the e

by nimish 5y ago
Yeah I think SyncE is what telecom RANs use to get within 5g reqs on timing. White Rabbit operates like 1588 + SyncE + a compensation model for the fiber link. It's pretty slick. It does need L2-L1 coordination but the ethernet MAC usu

Interesting. CERN has white rabbit for sub-ns timing. Needs special hardware but is now IEEE 1588 (PTP) "High Accuracy" profile. I wonder how this deals with the numerous retimers and DSPs required for really high speed ethernet.

You could see this happen in real-time as Intel sold essentially the same processor between 2015 and 2020 stuck on 14nm while increasing prices and lowering quality -- replacing solder with thermal paste, sticking with 4 cores as long as po

Those bootleg ARM processors would be banned in a flash by the US ITC, and on top of that who would fab them? No legit foundry would want to jeopardize their relationship with the real ARM. ARM China now has the designs for several-year-old

Of course. They are basically a privately funded research group at this point. No one has any idea how to operate a profitable fusion plant.

Sure you can, gas lasers exist. Stick your hand into the gain medium and have fun getting fried!

I don't think they'll have SPARC by 2025 but the physics work out. It's basically a bog-standard tokamak with superconducting magnets but with much more current capacity and therefore magnetic field strength from newer HTS. I

It's a rather enlightening exercise to work out how and why the earth is curved purely from the perspective of a human able to see maybe a small patch. This is directly analogous to how general relativity models spacetime as being intr

You've uncovered the fundamental issue with numerous public health studies: the effect size is irrelevant. You don't get attention for being modest.

A root user on the jump box can intercept data. https://news.ycombinator.com/item?id=19643977 is a nice explanation. The jump box is used only to establish a tunnel and you don't have to deal with multiple agents commu

ProxyJump absolutely rules. Much, much simpler than dealing with agent forwarding which is janky even at the best of times.
