Confusingly, on FreeBSD this option is SO_REUSEPORT_LB; SO_REUSEPORT is something different. I think the confusing thing was that Linux added an option and named it "SO_REUSEPORT" even though that name had meant something compl

This release brought to you from Las Vegas airport, where I was waiting for my suitcase to arrive. If anyone wants to talk about FreeBSD, I'll be at AWS re:Invent for the next couple days.

Indeed. Growing up in the 80s -- in a fairly middle class family -- a lot of my friends had bunk beds. Now "living wage" calculations assume that every child has their own bedroom.

Oh yuck. Invalidating all the pointers to the stack? That's got to be expensive. I guess if you're already doing garbage collection moving the stack doesn't make things all that much worse though... still, yuck.

by cperciva 2y ago
Aha, 2k stacks. I figured that stacks would be page size (or more) so 2500 seemed both too small for the thread to have a stack and too large for it to not have a stack. 2k stacks are an interesting design choice though... presumably they&

This depends a lot on how you define "concurrent tasks", but the article provides a definition: Let's launch N concurrent tasks, where each task waits for 10 seconds and then the program exists after all tasks finish. The nu

It serves the same purpose as asking customers "are you a terrorist" -- it creates an easily prosecutable offence.

The binary coding example would have been much better with Gray codes.

I'm not a medical doctor, but my understanding is that in the scenario of "patient's limb has been trapped/crushed for an extended period and can now be freed" you're supposed to tourniquet off the limb before

Attorneys (including defense attorneys), as officers of the court, are ethically barred from lying to the court or bringing witnesses whom they know intend to lie. Defense attorneys will sometimes tell their clients "if you're gu

A lot of the other "cures" involve immunosuppressants I'm optimistic about the VX-264 approach of islet cell encapsulation. Even if the encapsulation eventually breaks down, using stem cell derived cells (rather than cadav

Graviton has weaker memory ordering than amd64. I know this because FreeBSD had a ring buffer which was buggy on Graviton...

by cperciva 2y ago
We use atomic operations to update the pointers in a thread-safe manner Are you sure about that? Atomics are not locks, and not all systems have strong memory ordering.

Not even old languages, in many languages today (notably slavic) nouns decline differently with "1", "2", "3", "4" and say "5". Hence a wonderful piece of Soviet humour: A factory needs 5

If the network is connected, the first time you vote succeeds and marks you as having voted; subsequent attempts fail because they know you've already voted. If the network is not connected, your three remote ballots go into envelopes

Voter registration is reasonable, but it should be possible to register on Election Day, at a polling location, and it shouldn't take more than 5 minutes.

We just had an election in BC, Canada, and the way it worked here is that everyone has a "home" polling location which is responsible for ensuring that their vote is counted once and only once. If the distributed system is not par

Sorry, yes I only meant in the context of cryptography of course. NIST is a great organization and it's really a historical accident that they do anything with crypto.

by cperciva 2y ago
NIST is basically the publishing arm of the NSA, so it really depends on whether the NSA is taking the "protect national information assets" or the "attack foreign information assets" part of its mandate more seriously f

A single employee made that offer, was fired, and the case was referred to the police. Not exactly a matter of government policy.

Things stalled; there were a couple outstanding bugs (one I know has now been fixed, not sure about the other) and I had to take over FreeBSD release engineering and didn't have time to follow up on the Firecracker bits. I understand t

Pretty close in British Columbia. When you adjust for month to month shifts in the market (aka everyone's homes have appreciated X% since the last annual property tax assessment) the vast majority of sales occur within 5% of the adjus
