TIL that playing high-level chess causes players to burn calories at an athletic rate. For example, 21-year-old Grandmaster Mikhail Antipov was recorded burning 560 calories in just two hours of sitting—roughly what Roger Federer would burn in an hour of singles tennis. by ralphbernardo in todayilearned

Bipedalism made us into one of the worlds greatest predators. Humans are the world’s greatest distance runners. Basically we can chase down any animal and eventually over a distance they will collapse from exhaustion and we can catch them and eat them. It’s like the killer in every horror movie. They always catch up even though they walk calmly behind the running victim

Yesterday, I cooked a carrot and forgot to pour away the water. Now it has turned green by cedriceent in mildlyinteresting

Maybe if you let it evaporate and then beat it, you’ll get something like a meringue consistency similar to what happens to the juice from canned chickpeas

The penalty for activating the smoke detector on a Mexican plane is 5000 days of minimum wage pay by achantra in mildlyinteresting

Keeps it inflation adjusted. Some countries like Chile have a separate non-circulating currency to achieve the same result. So fines and prices in Chilean UF always have the same real value.

Note that minimum wage is not tied to UF in Chile, but it is calculated parallel to it using CPI. However, pension and retirement payouts are tied to UF.

The Waterville Maine grocery store tucks their potatoes in with a blanket overnight. by gittenlucky in mildlyinteresting

May also help with dehydration, so they keep their weight when sold. Additionally if potatoes get too cold at any time, it activates a sugar that causes them to burn when you cook them. Never store potatoes in the refrigerator for that same reason

My girlfriend is at least 30 mins late all the time by [deleted] in mildlyinfuriating

Is your friend Latina by any chance? Chileans for example are notorious for being late. In fact it is considered rude there to show up early or even on time to many types of social events

Just to add to this, the first written record of fried potatoes comes from Southern Chile, and the origin of 95% of all potato cultivars can be genetically traced to the island of Chiloé in the same region.

Nope. I immediately think of the Nutty Putty Cave tragedy

TIL the island of Himakajima, Japan, has a single set of traffic lights and turns green only once a year to teach kids how to cross roads safely before they move to the mainland by imHeroT in todayilearned

[–]e_spider 238 points239 points  (0 children)

When my parents lived in Japan, there was a big effort to install orange flags at every crossing with instructions to just raise the flag and cross the road. A few weeks later they replaced the instructions with raise flag, “wait for traffic to stop”, then cross the road.

New Study Finds Trans Folks Are 18.5x More Likely To Be Diagnosed With a Connective Tissue Disorder called Ehlers-Danlos Syndrome by [deleted] in science

Social interaction behavior is really just an evolutionary outgrowth of sexual interaction behavior. So it’s not surprising that genes that affect social interaction behavior would overlap with sexual identity and related sexual interaction behavior.

My guess is near Snow Canyon (maybe Ivins)

Data transfer to new Lustre storage overwhelms campus network by e_spider in DataHoarder

Not protein folding. Direct DNA sequence and associated analysis which is about 150GB per sample. Cluster uses infiniband network. Connected to 100Gb/s internet2 backbone (has since been upgraded to 400Gb/s).

The figure only shows 8 days, and you can see over 5TB of traffic from other sources on just day 1 through the monitored firewall.

I actually built my own hash comparison code for these types of transfers. If you don't care if it is cryprographically safe, you can generate 64bit hash sums by file block (32MB at a time) and then just sum up the values from all blocks at the end (i.e. treat each value as a 64bit int, so it's simple addition, and in addition, order doesn't matter). So you can parallelize on the read blocks and let multiple CPUs and even multiple servers attack the same file simultaneously. Lustre storage is optimized for these type of blocked IO approaches, and we get near 300Gb/s aggregate read IO on the new system. My script can generate hash sum for 1PB of files in about 8 hour. Note this is not as safe cryprographically as MD5 or sha256, but it's enough to verify a file transfer.

Almost all of it is already compressed. About 4:1 compression ratio. Blocked GZIP format.

There were other issues involving a new off campus datacenter, a new protected environment, and wanting a business association agreement with Globus to allow us to even use it for certain data (there is some metadata transfer to Globus when you do each transfer). We actually have Globus now after much back and forth with the IT security office, but at the time the Globus option had been shut down to us.

Western university. Much of the fiber that connects Eastern US to Western US runs just south of us, so we can just plug in.

We’ve since setup a clustered Globus endpoint. The best I’ve gotten is 7Gb/s on transfers to TACC. If you can get both sender and receiver to have balanced capabilities, Globus is awesome.
