It’s funny, my lab in grad school had a reasonably nice coffee shop on the first floor. So I have a lot of pleasant memories with my lab mates and supervisor while drinking pretty good coffee (sometimes with flat whites or single source lig

I honestly wonder whether or not they should have named Landis in this article, because he could easily end up the target of a lot of abuse due to this article (and how it demonstrates that he is a complete knuckle dragging moron).

Isn’t backprop just reverse-mode AD, which has been around since the 60’s? I get the impression that a lot of physicists and scientific computing researchers have been rolling their eyes at various ML “breakthroughs” over the years.

I’m not even thinking of anything as grandiose as a full simulation of the human, it could be as simple as mimicking the movements from a previous surgery using an overlay of the simulated robot arms.

by catgary 4y ago
I’m a bit shocked that simulators aren’t made readily accessible to surgeons. I thought that would be the biggest advantage of robotic surgery - a surgeon could prep with a few practice surgeries on the sim, while being taken through a few

What that company did to Tim Horton’s was basically an act of war against Canada.

So I was mainly a Haskell programmer in grad school before getting into scientific computing, and the main good habit I picked up was working at the REPL and breaking my code up into small, testable functions/components, and thinking v

It just sounds like he was never actually trained to program, and letting these bad habits persist isn’t doing him any favours.

Honestly, your story just indicates that someone senior needs to have a discussion with the applied mathematician about their coding practices (and they may even need a bit of training in that regard).

The Tullio library in Julia is a pretty fantastic option for Einstein summation. It’s performance is great, it generates CUDA kernels, and does some clever tricks for automatic differentiation. It’s also a bit more readable than numpy’s ein

That is hardly special to Python->Excel translation, and happens any time someone reimplements a piece of software.

Yeah, wasn’t there a good meta-analysis of the “Ivermectin treats Covid” papers that basics said “Ivermectin seems to treats Covid in countries where certain parasites are endemic, and if doesn’t where they don’t”.

I don’t know, it seems like the consequences of fraud change significantly once someone has stepped into the realm of medical research. Publishing fraudulent research seems like it is, at the very least, medical malpractice and should affec

What do you think the tensor product of finite dimensional vector spaces looks like?

Of course he has jurisdiction over that - Canadians don’t have jurisdiction over drunk driving in the US, but if you have a DUI you’re going to have a tough time getting into Canada.

by catgary 5y ago
I mean, Canada has jurisdiction over whether or not they can enter Canada, do business in Canada, freeze assets in Canadian banks, etc.

The protest was organized by white supremacists calling for the dissolution of a democratically elected government! Convoy protestors in Alberta were arrested with conspiracy to attempt murder! The discussion on hacker news has been insane.

by catgary 5y ago
The organizers of the protest were all different varieties of white supremacists, and their explicit goal was the dissolution of our democratically elected government.

Jesus Christ, just go look at the Ipsos/Nanos polls. Do you think CNN made that up out of thin air? Those are reputable polling agencies. Barely 50% of CPC voters supported the convoy protestors methods.

by catgary 5y ago
Yeah I think people forget that the protestors were making life miserable for tens of thousands of people with their incessant honking at all hours of the night. The rail protests just gummed up supply chains, this was actually harassing pe

No, poll after poll has shown that Canadians were overwhelmingly against the truckers [1], and a strong majority supported the use of the emergency act (there was even a point where bringing in the military polled quite strongly with Cana

I know University of Calgary had a bio professor who got in hot water for abusing animals (essentially: he encouraged his student to not anaesthetize animals before surgery to fudge numbers). So there are definitely grad students who will h

I feel like a country that was knee-deep in the trans-Atlantic slave trade like the Dutch doesn’t get to go isolationist once it becomes convenient.

I mean, it’s absolutely unfair to judge someone because of who their parents are. At the same time, it’s a bit amazing that people unquestioningly trusted the daughter of someone connected to a major fraud, and then she committed a major f

I mean, it seems like institutions like Yale exist to justify the US’s (insanely) stratified class system.

by catgary 5y ago
I guess the selectivity is what I take issue with - institutions like Yale/Harvard don’t really exist in Canada, and I think we are better off for it.

I always find the US system shocking, even just up north in Canada. UBC has comparable numbers of faculty + administrative staff, and services ~4x the undergrad population. UofT has ~50% more faculty and staff, and handles close seventy tho

It’s a type constructor that extends to functions. It’s a functor.

by catgary 5y ago
Type constructor that lifts to functions is even a pretty intuitive (ahistorical) intuition for “functor”.
