I'm grown increasingly dubious of unikernels; cutting out a layer of indirection by running the target process in kernel space seemed like a good idea -- as long as you didn't need, you know, multiple processes -- but it looks lik

I hated the transition to point and click, because it turned into "hunt for the right pixel" -- with text based games you generally only needed to be in the vicinity of the object you were trying to manipulate.

I learned to spell by playing KQ1 and SQ1. Well, playing the games and having parents whom I could ask questions like "how do you spell 'search body'". It's not just kids without exposure to English who struggled w

It was Space Quest 1 for my family and friends. "Insert disk into computer"? "Insert disk into drive"? "Use computer to read disk"? Nope, turns out the magic words were "Insert disk into slot ".

In the latter case, the delay window is up to 4 hours, which seems unlikely barring some natural catastrophe It's unlikely that one flight will be over 4 hours late; but the delay time which matters is based on when you reach your

You should subscribe to the tarsnap-announce mailing list. That's where tarsnap announcements are emailed out. (And yes, the above text is what I sent to the list.)

unacquire This reminds me of when some code was lightly edited to remove references to "master" and "slave", only to end up with a function "enminion".

Agreed. I'd like to get four or five nines rather than merely 99.9% availability. But the first priority is making sure that I don't lose anyone's data.

Refuse to defend gay clients, no. Refuse to defend gay rights, probably? The distinction is being drawn between the identity of a potential client and the nature of the creative work being requested. EDIT: I'm reminded of a recent ca

That's in Firecracker, time it takes to boot the kernel aka before we start running init. Including userland -- i.e. "boot to login prompt" -- it's around 450 ms on the same VM; I haven't optimized the userland bits

Not all code is slow. I can now boot a FreeBSD kernel in under 20 ms, which I'm pretty sure beats a 20 year old FreeBSD (not to mention a 20 year old Windows).

I've taken quite a few flights in E90s and was always impressed by them. I was sad when Air Canada replaced them with A220s -- of course I understood the politics of wanting to use a Bombardier plane.

I agree that there should be some mileage weighting; but on the other hand, long distance widebody flights are usually piloted by more experienced crew (they're preferable and flights are typically assigned by seniority). It would be i

Looking at this list I'm struck by the separation between narrowbody jets which generally make shorter flights (Embraer, 737, A318-A321) and widebody jets which generally make longer flights (A330, 767, 777). The exceptions of course a

Posting this here because (as pointed out by pg's recent tweet about Wikipedia) many people don't realize just how important a role Jessica Livingston has played "behind the scenes".

If you enjoyed this, you might enjoy my work porting FreeBSD to Firecracker. I gave a talk at BSDCan which will be on YouTube sometime soon, and also wrote it up for the upcoming edition of the FreeBSD Journal.

Negotiating voltage after being connected avoids the problem of sparking while the connector is being plugged in, but I don't think it helps with avoiding sparking in the process of un plugging the connector? Unless one of the leads

AWS does provide sponsorship for some open source usage of their infrastructure. They host some FreeBSD mirrors, for example. I've reached out to a couple of my contacts to point them at this.
