Gene Wolfe. Somehow resolves or explains every seemingly random occurrence throughout the story, even if the first person narrator is extremely unreliable and doesn’t make the connection

I grew up there in near rain forest area (just slightly short of the technical rainfall requirement). There aren't really any poisonous snakes on the island, just one type that has mildly irritating saliva (I caught and got bit by lots of these as a kid, barely noticed). Depending on which micro-biome you are in, there can be lots of mosquitoes, or not many at all. Where I grew up, there were very few probably because of all the predators (and most of the water was moving not standing). Caught a few tarantulas growing up, never got bit. There were some pretty giant centipedes where I lived but I rarely saw them, never got bit. A few bee stings, but nothing too bad- but wasps... hate those f**ers.

what struck me about Hawaii on my last visits though is the juxtaposition against Puerto Rico (the lost opportunities). Very similar in a lot of ways- but hasn't nearly leveraged the richness of its culture (history, music, cuisine, etc.) as much as Hawaii has.

many islands have similarly diverse environments packed closely together; doesn't make Puerto Rico any less beautiful though.

Thanks for the DD, I spent 30 secs scanning the article before thinking "this sounds like drivel, I'm going to check the comments"

I also like to point out in a few similar contexts: even if you could measure all the things, and you could create a perfect/optimal cost function, there would still be no guarantee that you'd be able to find the optimal global solution. So relax.

I am a researcher in academia that handles most of my system admin needs myself. It’s way cheaper to do yourself than some of these comments here make it sound (if you have good server rack space available). I ordered two 60 drive JBODs that I racked by myself (I removed all the drives first to lighten them) for ~82k. I used Zfs and 10 drive raidz2 vdevs for a total capacity of ~960TB of useable file system space. Installing the servers and testing some setups and putting it into use took about 4-5 days. In four years I’ve put many PBs of reAfs and writes through these and had to replace 3 drives. I’d estimate I spend about 2% of my active work focus on maintaining and troubleshooting it. Scaling up to 10PB I’d probably switch to a supported SDS solution, which would be much more expensive, but still way way cheaper than cloud.

It's a bit on a non-sequitur, but I am also looking at using MinIO as a S3 interface to a ZFS filesystem. Would be interested to hear from others about this use case for MinIO and possible alternatives.

I think deletes in ZFS are just slow, my guess is it is doing work to update/coalesce free segments lists so that future writes stay fast.

BeetleB is being disingenuous, the GOP fled and would not return until they were sure the bill died. There were other things that needed voting on- the climate bill was publicly dropped so that the missing senators would come back and they could vote on other issues. Putting the blame for this bill failing to pass on anyone but these senators is disingenuous by omission.

My guess is that ZFS is already pretty slow at deletes, your pool was pretty close to capacity and fragmented.

This was the first book I read of his, and it blew me away. Gene Wolfe has been my favorite author ever since. His writing was at just the right level of sophistication where it was still accessible to me (I couldn't finish Ulysses) while being thoroughly enjoyable. His attention to detail and casually tying off loose-ends is pretty stunning when examined carefully. And he is one of the few authors whose books make me feel like I'm having a lucid dream.

My Mazda 6 manual has a very smooth and light clutch and “hill assist” where the car will brake for you on hills as you ease into gear. It’s an awesome combo and I get virtually no fatigue from driving in stop and go traffic trough hilly areas. My old manual though was another story- you’d have a sore leg after a long drive in bad traffic, and getting stopped on a steep hill with the automatic drivers crawling right up to your rear was nerve wracking.

What amazed me the most from the first Snowden leak was that the NSA was vastly more effective and competent in their efforts than I had expected.

I've seen this nonsense spouted a few places now. Personally, I think there is a big difference between the two, one focused primarily on cheerleading to get out the vote, the other using inflammatory fabrications to enrage your base (and get out the vote). I see this as a classic example of when "the ends don't justify the means".

Just last week Google maps directed we take a turn going down the wrong way of a one way street that was already clearly marked as one-way on the map- yeah, I'm not too worried about even Google's dominance in this area.

Also, Apple maps in my area has been quietly, but steadily improving. Still not as many POIs as Google, but nicer interface and turn-by-turn (IMO).

Yes. I was going to add that the lines in the original image are more likely due to the discontinuity between the top, bottom, left, right edges. The other comment wasn’t mine, but is right that an aperture in the back focal plane of a lens would cut out image information at higher resolution.

The very strong 45º lines in the rotated image are probably mostly artifacts caused by the image edges seen in the rotated version. A rotation in real-space is equivalent to one in reciprocal space, so the two transforms should look the same (barring the interpolation differences, etc.) but rotated.
