@channingwalton yeah, as much as I hate Eclipse and love VS Code, Scala IDE for Eclipse was pretty fantastic and switching to the Dotty plugin for VS Code was a big step back for my productivity....

@pokateo recently found an online dataset that could be opened in ArcGIS Pro, but had some weird setting s.t. you couldn't re-export it as a shapefile 🤔

@ricci @regehr @eeide time to start lobbying for a university-hosted IRC server? :D

@adrian @regehr Cache / memory hierarchy effects are of course very strong too, so it’s possible a smaller working set and less pointer chasing still wins out over the contention issues, but an interesting phenomenon to consider

@adrian @regehr FWIW, denser data structures may actually have adverse effects if you need to insert/remove elements dynamically. The standard binary heap implementation (relying on fullness for its depth bound) concentrates contention along paths between the leaves and the root, where a Braun heap (relying on balance for its depth bound) diffuses contention.

@adrian @regehr if you haven't already, it's probably worth reading the HPC literature on implementing Barnes-Hut style tree approximations on GPU. There are some pretty neat tricks in, for example, arxiv.org/pdf/1106.1900.pdf

- unsigned_root = p**third
+ degenerate_p, p = _safe_denom(p)
+ unsigned_root = tf.where(degenerate_p, tf.constant(0., p.dtype), tf.exp(third*tf.math.log(p)))

Can we talk about how, to the consternation of parents everywhere, toddlers turn every single thing you give them into a Non-Fungible Token.

Gotta love the polarization of fandom where half the takes I've seen on Season 3 are complaining about "Glup Shitto" and "why does everyone in the galaxy know each other" anytime we see someone we've met before, and the other half are complaining that Luke isn't showing up to save the day 🧐

Just one example: news.ycombinator.com/item?id=3

"I have a rail line right under my apartment, so I built a small computer vision app running on a Rasperry Pi which records each train passing, and tries to stitch an image of it.

It has a frontend at trains.jo-m.ch/"

@andrewliptak thought I saw you were on the exhibitor list for the VT SF/F expo but didn’t spot your booth anywhere?

@simon_brooke @olimould visiting some of the palaces around St Petersburg a few years ago was eye opening in a "oh neat, this is what it looks like when you dump an entire empire's GDP into gold leaf" kind of way and also in a "well no fucking kidding that they did a revolution" kind of way

Here's the thing. I think this confusion is ubiquitous in the medical literature

Some paper shows that there is a statistically significant difference in groups.

It may or may not be making misleading claims about how this implies mechanism, even though the data themselves reveal massive overlap in group trait values. Either way, subsequent citations uncritically state mechanism has been established. And a false fact is canonized.

This is why Sam's paper is my must-read paper of the month.

@regehr @palvaro every action has an immediate reward signal with large absolute value

@regehr @palvaro one of my favorite core-strength and balance exercises in the summer is what I like to call “blackberry picking yoga”. Appropriate attire: minimalist footwear, cargo shorts, and a Tupperware.
