what an amazing article packed with very useful physics insights. Need to follow up more on the last idea of the gaussian random force and the quantization of Newton's equations. Even the opening sentence had me try to remember some of my DE by expressing the rational faction via the technique of the variation of constants :) (have to admit that i felt too rusty...). Thank you for posting this!

My employer cannot hire H-1Bs.
You must be a US citizen to work for my company. No "US Persons" (visa holders) or foreigners allowed.
You have to be eligible for a Secret security clearance. You don't have to get one if you don't want to as there is usually plenty of uncleared work to go around, but you have to be eligible in case that goes away and we need to put you in for a clearance.
We cannot find qualified applicants.
I've had this conversation many times on HN so here are some preemptive responses:
No, we don't make weapons for the military. Well, we do but not my part of the company. The most harmful thing the products I build do is quantify in precise detail how climate change is dooming us all.
No, our positions aren't ghost positions.
Yes, we are willing to train someone who is motivated. We won't re-teach linear algebra to a developer applicant but we will pay a tech writer to go to school nights/weekends to get a degree in engineering (me, I did that).
Yes, we have extensive high school and college work-study/internships and participants make $72k/yr. with full benefits for the duration of the program. That pipeline is actually successful.
No, you can't work remotely. You (even programmers!) have to touch the things we build in order to build them and nobody has an ISO certified clean room in their house.
Yes, we pay well.
No, we don't pay as much as Meta. We build components for satellites that have been sold to space agencies and purchased by various departments/ministries of the environment, not your personal information to advertisers-- one party has more money to spend than the other.
We have shortages in mech/EE/Aero, shortages in software, and critical shortages in engineering technicians.
One issue is that we expect programmers to remember linear algebra and have more than the ability to shovel frameworks on top of each other until a phone app comes out the other side.
similarly i am in this ridiculous position. I am a security engineer, wanting to work in vulnerability research. Got an EB2-NIW green card due to my skills being valuable for the national interest. Can't even get an interview because all vulnerability researcher positions require TS clearance... I guess i will just have to wait 4 more years for the citizenship, but it's a pity.

Why is it written in C++, when Google made Wuffs[1] for this exact purpose?
this is a valid question why is it being downvoted?
Thanks. This is awesome. I think they are doing more work themselves in terms of crypto, whereas we rely on QUIC+TLS more.
Regarding holepunching, our approach is a bit less pure p2p, but has quite good success rates. We copy the DERP protocol from tailscale.
I am confident that we have a better story regarding handling of large blobs. We don't just use blake3, but blake3 verified streaming to allow for range requests.
Also I wrote my own rust library for blake3 verified streaming that reduces the overhead of the verification data. https://crates.io/crates/bao-tree
I tried to get on their discord at https://veilid.com/discord, but I get an invalid invite. You know a better way to get in touch?
hmm this is strange, i tried the invite and it worked for me.
If you are on fedi, @thegibson@hackers.town is part of the team.
thanks for the links, i will get in touch personally when i try ir0h :)
This looks very interesting. They made very similar choices than we (iroh) did. Rust, ed keys, blake3.
They seem to do their own streams, while we are adapting QUIC to a more p2p approach. Also the holepunching approach seems to be different. But I would love to get more details.

this was the presentation at DC'31. i will also check out iroh! thanks for working in building something in this space, it is much much needed!
if you are looking for something similar to ipfs but a bit more minimalistic and performance oriented, check out iroh https://github.com/n0-computer/iroh .
It is a set of open source libraries for peer to peer networking and content-addressed storage. It is written in rust, but we have bindings to many languages.
One part of iroh is a work in progress implementation of the willow spec. The lower layers include a networking library similar to libp2p and a library for content-addressed storage and replication based on blake3 verified streaming.
Most iroh developers have been active in the ipfs community for many years and have shared similar frustrations... See this talk from me in 2019 :-)
https://veilid.com/ should also be a great alternative. i haven't had time to use it yet, but it was built to address performance issues with ipfs and allow for both dht style content discovery, but also for direct websocket connections for streaming (and doing that in an anonymous fashion)

You can use `ifconfig` / `ip link` if you want. The submitted article is about having systemd-networkd manage it.
i would also need wpa_supplicant for the wifi though. i would also need to install ifconfig or iptools and making sure that systemd/network-network manager respects my config. I would also need to figure out the interface's name-du-jour or add udev rules to force a name of my preference. I hope you see my point.

I'm sorry but i fail to see how this is _simple_ networking.
It shows the state of Linux these days.
Compare that with OpenBSD's interface to do the same thing.
wired: ifconfig [if] autoconf up
wireless: ifconfig [if] join [ssid] wpakey [pass] autoconf up
Consistent documentation existing in man ifconfig. The sad thing is that Linux used to be designed not evolved.
I feel privileged to watch this. I live in north Africa and I feel like taking a flight to California to go visit him, inquire about his health, tell him about my children progress at school, show him how much I love him and how much I'm grateful.
completely agree with you. ken and the not so big group of people who has positively shaped all our technology really need more appreciation from us users, although i'm sure he would be weirded out by it like any proper geek. That been said: thanks ken!
