Demoiselle crane flies over Himalayas and over Everest during its yearly migration, so it'd be flying at least 30k feet high.

I only know that from Planet Earth documentary, which was such a great show!

Unless I screwed up the math, they would be quarter of a light year apart. Plenty of space for each black hole to form its own accretion disk.

Kepler’s laws should still provide a pretty good estimate, at least until black holes get much closer. I did a quick back of the envelope calculation, and looks like they’ll be roughly 14k astronomical units, or 0.22 light years apart.

1604. One could say we are overdue. I’m not sure about dust or other obstacles blocking it, but based on brightness alone a supernova in our galaxy should be visible with naked eye.

New comment by ardel95 in "How do merging supermassive black holes pass the final parsec?"

ardel95 — Thu, 24 Oct 2024 15:03:43 +0000

It would be. Which is why any pair of orbiting bodies will eventually collide.

It’s just that for black holes this effect is insignificant (a merger would take much longer than the age of the Universe) until they get close to each other, much closer than 1 parsec.

The potential to detect Supermassive Black Hole mergers is one of the reasons I'm really excited about the LISA project [1], and hope it actually gets funded and doesn't delay too much.

New comment by ardel95 in "AI Needs Enormous Computing Power. Could Light-Based Chips Help?"

ardel95 — Tue, 21 May 2024 13:59:06 +0000

In quantum mechanics, bosons are (often massless) force carrying particles like photons or gluons. Fermions are the massive matter particles, such as electrons or quarks.

So, while I’ve never heard this saying before, I assume it’s meaning is that massless particles like photons are best for carrying information around (rather than electrons we are using in circuits today), while the electrons are best for carrying state, like in a switch.

Note, that in networking we have already made that transition by using fiber optics, rather than electric wire to transfer information over longer distances.

The article didn’t mention this, but don’t u128s get mapped to SSE2 registers on most modern x86_64 processors, and not regular 64-bit ones?

New comment by ardel95 in "Majority of web apps could just run on a single server"

ardel95 — Sun, 24 Mar 2024 23:56:00 +0000

That’s a pretty pedantic interpretation of the word application. In the context of software owned by most teams, that they may decide to run on single vs multiple hosts most applications are absolutely stateless. Most applications outsource state to another system, like a relational database, a managed no-SQL store, or an object store.

And so no, most teams don’t need to worry about the hard problems you bring up.

Totally. But most applications are not stateful.

If you have the ability to spin up a new machine when the old one fails, and deploy your app onto it in one minute, it’s not a big leap to also run your app on two machines and avoid that downtime altogether.

New comment by ardel95 in "So you think you understand IP fragmentation?"

ardel95 — Sun, 18 Feb 2024 01:31:36 +0000

Almost every modern router in a multipath network peeks at the next layer to implement flow hashing correctly.

ardel95 — Sat, 17 Feb 2024 18:28:33 +0000

One of the biggest misses with IP fragmentation was not requiring each fragment to carry the higher protocol header. Or at least do that for UDP.

That decision alone would’ve made fragments so much simpler on network devices and appliances, and much less likely for them to get dropped.

That would effectively kill software patents. Which is a fine outcome.
