Before gastropods evolved, stromatolites were significant reef builders. In the Ordovician, tabulate corals were important reef builders, although they mostly form patch reefs. Stromatporoids (kind of a hard sponge - they're weird) wer

That's really misleading. There are large spans of Earth's recentish (i.e. Phanerozoic) history where there are aren't significant reef building organisms at all. Furthermore, "bleaching" is very specific to today&

Keep in mind that the energy expended in C02 sequestration is concentration. It's easily soluble in water when injected and then is reactive to produce mineral precipitates. And that's only the geologic sequestration. There are m

ShakeAlert and similar systems are awesome, but not exactly what most folks mean by a prediction, FWIW. They're meant for warnings of seconds, but not for things on the scale of minutes or hours or days. Not to take away from ShakeAle

I really want to write up a long response to this... I used to be closely adjacent to this field, and I do ML work in other domains. ML is mostly irrelevant for this, though. Here's the short version: We're good at predicting whe

It's highly imprecise, but not impossible. The alerts are already "this is over some threshold of ground acceleration", so there's an inherent severity estimate in the alert going out at all. But expected intensity info

Put simply, no. The details are messier because groundwater flow very much does affect earthquakes (poroelasticity), but by and large, seasons don't affect groundwater flow significantly at the depths involved. E.g. wet vs dry weathe

It's less that and more that you're not maximizing retirement savings at that point, which is something that stresses a lot of folks out. Also, even within software, I can't imagine trying to find a job with a 6-month gap on

I can't really agree that VS Code or Helix are "great out of the box". I haven't tried zed. VS Code feels really awful to me (note: this is probably just me) without weeks spent re-configuring it. Even then, it's

As pointed out in the original article, if they were trying to clear hydrate blockages without coordination with folks at the "other end" of the pipeline, it could make sense that they'd try to operate on both in the same tim

by jofer 4y ago
This really is a plausible scenario. Hydrate buildup is a very real risk in a pipeline that isn't flowing. Trying to deal with it in a less than ideal way can absolutely lead to loss of containment and would explain the multiple leaks

It's not logical, but it is a standard on the finance and business side of things. MM is universally "million" there, be it dollars, liters, barrels, etc.

I've been working 100% remotely for about 6.5 years now. Overall I love it. However, there are very real drawbacks that have taken me awhile to fully realize. For me, the primary one is that it's _way_ too easy for everyone to ge

Ideally, yes, but the pepper still winds up fully cooked, it's just that it's not mush. You want to blister the skin so it peels off easily. That's the main goal, but a lot of flavor comes out of caramelizing / charring

I kept reading that as "paleogeography", which is a common geological term. (i.e. reconstructing ancient landscapes) Weird how the brain jumps to "term I know" rather than actually reading a word.

That's more of a "you didn't mention my recent research on this" than frustration with the "usual scientific news cycle". (The commenter does have a good point, though -- the writeup is on "Hey, these obse

It's a matter of how you interpret and use them. If you think about it as "strong suggestions", then yeah it seems obvious that they're suggestions for how to approach ambiguous situations. However, that's also mis

The issue with using S3 cells as a raster is the inefficiency in storing information. You're basically making a row in a DB for every _pixel_ with the S2 approach. The main point of raster storage is that it avoids the overhead associa

More generally, gdal is a raster I/O library. S2 is a point only system. It's not meant to store or work with raster data in any way. (Sure, you can represent raster as points, but it's hideously inefficient to do so.) Basica

EPSG:4326 doesn't really use lat/lon. Sure, it's in the spec, but that part is irrelevant. Everything is stored in lon/lat for any relevant format when the projection is EPSG:4326. There have been some unfortunate decisi
