I had a different initial confusion - it seems this company has no relation to the company formerly known as Typesafe https://en.wikipedia.org/wiki/Akka.io
The article is talking about symbols that were lost. The sentence should be interpreted as "these [symbols], for Insert (now gone) and Delete (still with us)". The photo is of a symbol for 'insert', an 'a' with a caret above it.
Some of the details in the paper are super cool. Since the game pulls "c" down to near walking speed, you receive photons at different rates depending on their direction relative to your motion (relativistic aberration / searchlight effect) resulting in neat visual shifts.
I don't usually download games, but I might have to make an exception just to try it out.
They link to their code on GitHub - see footnote 2 on page 2. I don't see it linked anywhere else, which makes it easy to miss. https://github.com/rjha18/vec2vec/
I think they've gotten worse about this as an organization over the last few years(?). Earlier this year an update to their mobile app introduced loading time, and resulting slowness, for opening menus that used to be ~instant. To me that smacks of once having known not to do that, but that knowledge having been lost (or priorities having shifted).
More specifically, I'm talking about tapping the '...' on a track for the options menu. That should be latency-free, and used to be.
Cities on the water make fun shapes for obvious reasons. Atlantic City, Seattle, Chicago, Galveston, New Orleans. The slices can go very far or even be omitted due to not hitting the contiguous US. Chicago's is probably the most interesting, they cross Lake Michigan before getting sufficient density to stop.
> I'm sure the record standing so long is partially down to the fact the mile isn't run at major championships
I'm not so sure about that. The 1500 is the equivalent race run at major championships (and most paced time trials). But that record (3:26.00 by Hicham El Guerrouj) has stood one year longer, and is generally considered a stronger record. This is possibly the closest anyone's ever come to an equivalent performance to the 1500 record, in either the mile or the 1500. The second-fastest 1500m time ever is 3:26.34 by Bernard Lagat in 2001. The World Athletics scoring tables value a 3:42.66 at about 3:26.3, eyeballing the midpoint of given values. (Or taking the WA point values on the top lists, Josh Kerr's new mile record is 1298, Lagat's second-best 1500m is 1297, and El Guerrouj's 3:26.00 is 1302.)
I don't know whether the WA points or other conversion methods actually have small enough error bars to distinguish between the Lagat and Kerr performances, but the 1500 record beats the mile record by a big enough margin that I don't think we need to worry about that.
Some years ago, I heard that a rough metric for regular athletics: humans slow down by about 5% for each doubling of the distance. If that is accurate even between 100m and the mile, then extrapolating the world 100m record (9.58 seconds) out to the mile would suggest a mile pace of 12.84/100m.
Kerr ran an average of 13.837/100m. If the 5% rule is truly accurate (which is unlikely), there's some scope for faster times. Personally I'd bet the 5% is just a handy rule of thumb that doesn't do much more than to indicate that these are incredible athletes operating at the absolute peak of human performance.
