It worked 4 days ago, no less! (I search on a ~daily basis for mentions of "cperciva", "Tarsnap", and "daemonology.net" to see where I and/or my work are mentioned.)

Correct. You could construct a weird scenario with a buggy side channel attack where using a different value for d would matter, but generally speaking the attacker doesn't know and doesn't care what value (out of the infinitely

This isn't used in practice because if you care about efficiency you're not calculating M^d mod N; instead you compute exponents mod p and mod q and use the CRT to combine (as mentioned in the author's link to "Garner&#x

Definitely a massive job. Some FreeBSD developers have stepped up to volunteer tremendous amounts of help (and also the FreeBSD Foundation has paid staff helping out with parts of this) but my best guess is that I'll be spending aroun

Target is 2025-12-02 00:00 UTC. Given that this is a major release, there are fairly wide error bars on that; it could be as much as 3 weeks earlier if the first release candidate turns out to be perfect, and of course it could be later if

Release engineering for FreeBSD 15.0-RELEASE. Major releases are always a lot of work, but this is probably the biggest release in 20 years due to the new base system distribution system landing. (We're switching from "here&#x27

Google maps has been able to figure out parking structures for me recently. Not sure what technology is involved (gps isn't great for vertical) but it's clearly possible.

I've done this on EC2 -- in particular back in the days when EBS billed per I/O (as opposed to using a "reserved IOPs" model where you say up front how much I/O performance you need). I haven't bothered recent

Currently, everyone only flies wide-body aircraft. Air Canada operates YUL-EDI and YHZ-LHR on 737s, and WestJet operates YHZ-BCN, YYZ-EDI, and YYZ-DUB. And that's not even counting the dozens of flights to and from KEF (which might

Good news! This is exactly how the free tier works now.

I don't blame them. That problem statement seems to be deliberately confusing.

Right, using beta is more convenient and also it's better behaved since it doesn't have the weird "goes to infinity then comes back from negative infinity as you keep increasing it" behaviour.

The Bank of Canada did a report about this a few years back, and found that cash was the cheapest payment form for merchants to handle for transactions of up to $6 while debit cards were cheaper above that point; credit cards of course were

In particular for "Ownership", the part about "They act on behalf of the entire company, beyond just their own team." does not at all mean what the author implies, and is well connected to the rest of the description in

The Leadership Principles are less "principles" and more "operational guidelines". Aside from maybe "Strive to be Earth’s Best Employer" (which is a recent addition) they're not saying what Amazon wants t

To be clear, I'm not saying it has to be literally Paxos as a service. There's a bunch of ways you can take operations from different sources in a distributed system and produce a consensus view of what happened first. But aside

The British Commonwealth isn't entirely different from the Barbarian Kingdoms -- a lot of the political structure (elections to a Parliament modelled on Westminster, a nominally apolitical civil service) have been largely retained, and

There are several advantages to using spiped rather than tunneling via ssh: * Reduced attack surface: The spiped protocol (and implementation) is orders of magnitude simpler than ssh. * spiped opens a separate transport layer connection for

I have a 40V (well, 2x 20V) mower, and use two pairs of batteries to mow the lawn. But that's fine; between the lawn mower, the leaf blower, the weed whacker, and the snow blower, I've got plenty of spares.

Good enough for what? I'd love to have a lawn mower which can dump grass clippings in my compost pile (mulching them and leaving them behind is better for the lawn, I know, but my wife is allergic to grass so this would basically mean
