You can buy upload credit with seeding bonus on some trackers, and there are nearly always freeleech downloads that don’t count against your downloads, but do count for uploads. It’s usually quite easy to maintain a ratio.
I’ve worked on several systems that had enough flop/s to make it in the top 5-10, but for which we never submitted benchmarks. Sometimes their backend network layout technically would make them several smaller clusters for an HPL run, sometimes it’s because the cluster is too heterogeneous to get a good benchmark result, and sometimes it’s because the employer wants to keep a low profile.
Most of the time, it just that it’s a hassle. It takes a while to prep and tune a big hero run for benchmarking, and if you spend a billion dollars on a cluster, it’s making you a lot more than that. Taking it down for a day or two stops the money printers.
You still need to traverse physical segments in the wireless path: think receiving dish to the next transmitting dish, the end of the path to get from the trading systems onto the roof and into to the first dish, etc. Every nanosecond counts.

They’ve been using hollow core fiber (and funding research into it) for nearly a decade. I know it goes back further than the 2017 spinoff mentioned in the article, but https://optics.org/news/11/9/52 talks about it a bit.
> But what about Jump Capital? They have a crypto division that also does market making. The difference here is there are given a large chunk of tokens to market make with, as they please.
It may be a little early to make that comparison. Jump is still being investigated for its crypto shenanigans.
I think it’s a way of keeping the museum’s single most popular piece of art on display whilst working it. I think most museums would remove it for a while, but so many people come specifically to see this painting that they want to keep it viewable, so they make a little show of its restoration.
I dunno; I’ve been through that floor 5 or 6 times since they started work, and people always seem to love the spectacle of it.
Or have them set up in a way that makes them hard to run full-system benchmarks on. I can think of a couple of financial firms that have clusters that would rate on the Top 10, but a) as you suspected, they’re too busy running the money printers to take them down for a few days to run benchmarks, and b) they’re split up into more manageable little clusters, so the high speed fabrics don’t connect and allow every node to talk to every other node, which you need for an HPL run.
Do you have issues with other rollerball pens? I’m also left-handed, and really struggle with them (especially the G2). My issues seem to be that when I’m pushing the point across the paper, rather than pulling it across like a right-hander would do, they often dry up and there’s no ink coming out.
I like how quick drying gel pens are, but I haven’t been able to write with them consistently. If that happens to you with other rollerballs, I’ll give that Pentel Energel a try.
I had the same issue with the G2. I've always noticed some skipping with rollerballs, but none were as bad as the G2. It was astonishingly hard to write with.
The Energels and Sarasas are the best pens I've found: affordable, nice to use, reliable, and refills fit a variety of pen bodies. If there's skipping, wiping off the tip of the pen to remove any grime resolves it.
In case it's helpful: I place my hand under the text I'm writing, aka "underwriting" and use light to medium pressure.
