https://pages.cs.wisc.edu/~dbbook/ is a great overview, specifically chapters 13 and 14 on query optimization. it is difficult to reason about though, and every compiler is differe…

it's sad to see this location go. it was such an amazing store on the inside. the theme had some great homages to Mars Attacks!, as well as a great many other sci-fi films. this al…

anyone cheering this on really has no idea how bad this is. higher education is an area in which the US has had a completely dominant position. the smartest and most driven people …

i think this already happened to some extent, with the Social Security Administration. unless something's changed it's all stored in IMS, i.e. pre-relational. perhaps there's some …

btrfs has similar aims to ZFS, but is far less mature. i used it for my root partitions due to it not needing DKMS, but had many troubles. i used it in a fairly simple way, just a …

It's too bad they didn't put a roundabout here, there's one in the middle of old town Orange and it works pretty well. Terrible waste of money to make the intersection worse like t…

yeah, you could argue that the RIVA128 was the first successful PC GPU that didn't require a separate video card, but that's not the same thing.

we do have semi-autonomous trains, in the US at least. i'm not sure about elsewhere. PTC stops a large class of disastrous operator errors (overspeed, missed/ignored signal, etc.).…

the resistance is a problem. there are a few in Pasadena, CA on Los Robles between California and Raymond where it's a roundabout, with stop signs on each entrance. the worst of bo…

stop and get out of the car because someone just got flung onto/underneath your car? or perhaps have enough situational awareness to see that someone is about to walk into oncoming…

A Brompton is really small when folded. Smaller than a carry-on suitcase by volume. It rolls on little scooter wheels on the rear rack when folded. I bring mine into all the places…

That’s really awful. These kind of incidents need to be investigated. Whatever situation caused the car to just run into the path of a pedestrian in a crosswalk can’t be allowed.

don't they do this with crab pots? i'm not sure how far those go down though.

At least on the crash carts I've used, the displays were always VGA. Not sure if that's still the case. I'm not sure why.

I always hear a lot of grousing about DB, but I took it a lot the two times I visited, and I liked it. Even when there was a horrible windstorm that blew trees all over the tracks …

I know they started testing a while back in LA, has anyone been in one there? I haven’t seen them around town like I have in SF.

It's fine if you, your coworkers, and your manager have the discretion to understand vacation is not optional. I've never seen this. It usually ends up being a race to the bottom, …

An induction range draws a great deal of current, so it might entail a lot of very expensive electrical work. Many places that have gas appliances weren't designed with the idea of…

It seems very much like throwing the baby out with the bathwater to ban them outright. Require a fume hood, and if that is not enough then at least just ban it for new construction…

Most headunits with Carplay require you to have the vehicle speed sensor connected to them. They also have a compass. So, if you lose GPS, you have the 3 components you need for de…

This is the exact method by which many classic Tiki cocktails were kept secret and therefore nearly lost to time. For example the original recipe for the Zombie is disguised twice.…

It can get kind of confusing though. Consider the Navy Grog, a classic Tiki cocktail. The Trader Vic’s recipe is very different than the original Donn the Beachcomber version. This…

Airbnb is such a joke now. I had a host steal from me with no repercussions in November. The host said the room wasn't ready through text, and then, when they said it was ready, so…

This reads like a less amusing version of the UNIX-HATERS handbook. The citation on the Linux kernel containing "a whole lot of very low quality code" is a Slashdot post. The autho…

I built a custom home server using Mini-ITX form factor parts and I would have to agree with this conclusion. ECC ram in that form factor is very expensive. The biggest issue I had…
