This is almost an argument for not publishing code. If you publish all the equations, then everybody has to write their own implementation from that. Something like this is the norm in some more mathematical fields, where only the polishe

Perhaps a more direct Julia analogy would be the built-in AbstractArray interface. There is simply no question of how (to use their example) `mean(::CuArray; dims)` should work, it not only follows Base's notation, but extends the same

This bakes in a particular version of the Plots library. Which is mostly great, but you need to re-bake to move on to a new version. (All the standard libraries are baked in by default, in much the same way I think, and so can't be upd

I think these overhead numbers are quoted as the percentage on top of what gets spent, rather than the percentage of the incoming cash. 50% overhead means that buying a 1M machine involves giving 500K to the institution. (Still crazy high,

In case this isn't clear, the telemetry being discussed is only doing anything when you ask the package manager to connect to a server, to download things.

Anyone have long-run comparisons on fluff buildup? Hard to gauge changes in clothing / cases / etc I guess, unless you literally live with two phones.

Haven't seen the movie but it is one of the drugs prescribed for altitude sickness. Or rather, one of the ones often carried for use in life-threatening cases.

>if you're building a new line, you may as well make it high speed; I think the thing to understand here is that mixing speeds is awful for capacity. There are some fast trains now, and everything else has to be scheduled around the

Does the arxiv accept xetex yet? That's one constraint which kept me away.

The heavier version looks better, but this involves messing with Metafont, which generates bitmaps. (And sadly his sample PDF links have died.) I don't know of a way to heavier outline fonts. I believe the commonly used versions aren&#

I think this is quite a hard problem to solve. A Python wrapper of some some monolithic C library can check & reject any input which doesn't meet the spec, and tell you why. But a Julia library typically wants to be generic, you sh

These are true. But also, I think some of the weirdness is that a lot of people only do this once, struggle, and then move on. So the forums are full of people trying to find others with the same problem which none of them understand.

By Adirondacks I think GP means the whole mountain range, https://en.wikipedia.org/wiki/Adirondack_Mountains . Would be curious though to know whether OSM has those roads.

On an iphone, I can't recommend https://mapout.app/ enough. It's simple & good-looking, it's easy to download tiles of the area you need (not countries) while on wifi, but designed to work mostly offline.

You're missing cmd+L (copy last command to cursor) and cmd+shift+L (last result). Although, as others have said, many prefer the style of editing and re-running, rather than leaving the history above.

No insight into Australian management, but having lots of valuable dirt to dig up does make it much harder to get going in other lines of business. I think this is called "dutch disease" by economists: the high wages paid by the d

A key idea here is that, to keep this support, the firms were also obliged to export. Even small numbers, at a loss, at first, but they had to have paying customers in America. Firms that couldn't do this were allowed to go bankrupt &#

If you found one, you get to brag about it. Give regional ted-X talks. Schmooze with people closer to the money than usual. I presume that's the main point.

Just reading what everyone does may work. Here's a tiny package: https://github.com/ChrisRackauckas/EllipsisNotation.jl I think that `/src/Name.jl` must have the main module, and `/test/runtest

How would you like modules to work? It seems great to me that paths & source files are mostly irrelevant, you're free to re-organise without changing anything. And that `using Xyz` is always talking to the package manager. You can

Not my field, but at least some of it appears to be worked on seriously. This was an interesting recent blog post about making DNA-sequence processing go fast: https://biojulia.net/post/seq-lang/

Even turns in the vertical direction are a problem, for uncomfortably pushing you into your seat, or lifting the train off the rails. Which results in more bridges & tunnels than would otherwise be needed. Unlike slow trains, there is p

Curious whether you've compared it to https://github.com/chriselrod/LoopVectorization.jl ? Which if I understand right is a pure-Julia attempt to use many of the same tricks.

Sure, hopefully there are many details which we could ignore, like we can ignore what the planets are made of. But from what we know about how nature works, I suspect a lot of little details are going to matter. Flies are pretty highly opti

That's neat. It's perhaps worth mentioning that this trick is only needed when your computer understands complex numbers (1,i) but not dual numbers (1,ε), where i^2 = -1 but ε^2 = 0.

Citing papers which aren't yet published by their arxiv numbers is routine. (And, before 1991, people did the same using the author's institute's preprint numbers.) If they have appeared in a journal by the time yours is acce
