So your coworkers, presumably health care professionals, refused to accept the most basic public health measure, and expected to keep working, presumably in proximity to vulnerable populations? I hardly think their employer is the unreasonable party here. (E.g. I also wouldn't hire a lawyer who advocated trial by combat or a chemist who advocated alchemy...)


Calling it a public health measure is editorializing. Since vaccines do not prevent transmission, I think most rational people would prefer an unvaccinated nurse that doesn't have covid vs a vaccinated nurse that does. The only official line left as far as I know is that vaccination "prevents severe infection". So is the rule still in place for the sake of the unvaccinated nurses?

And I'm not trying to be ideological here - if I've made a factual or logical mistake, I'm happy to be corrected and will own it


You are just one of those die hards who refuse to see a rational argument and change your mind no matter what. There really is no point in arguing with someone of your mindset. You worry about vulnerable populations, well did you read the part where I stated they wanted covid positive workers to take care of the vulnerable population? Please tell me how you can rationalize that this is better then having a non vaccinated worker who is not sick with covid and is of no risk getting the client sick?


That's not even how a precedent works.


Oxford definition: "an earlier event or action that is regarded as an example or guide to be considered in subsequent similar circumstances."


The operative word there is "similar."


Yes, similar as in "if we don't do that, insert_whatever_crazy_idea_here, we're gonna overwhelm the hospitals!!!"

Because it's been the justification from day 1: "not overwhelm hospitals".


Yeah, that's not how precedent works. Precedent is used to justify the means, not to point out that past actions had the same or similar ends.



You might also like "Fluid Engine Development" if this stuff is your cup of tea. I believe there is complete code with it. https://fluidenginedevelopment.org/

..and if it's really REALLY your cup of tea, join my research lab and do a PhD. :-)

No need for shame!

"He did not wait for students to come to him; he made inquiry for promising youthful collectors, and when he heard of one, he wrote, inviting and urging him to come. Thus there is hardly one now of the American naturalists of my generation whom Agassiz did not train." - William James, Louis Agassiz, 1896.

For context, Chris (batty above) was one of Robert’s best grad students.

If fluid simulation is your thing, Chris is one of the best people in the world to do a PhD with.

He’s also a very nice person. :)


I want cross-platform deterministic fluid simulations (at least in platforms with IEEE 2008 float semantics). What I mean is, I want to run the same software on different architectures and platforms and get the same exact answer. Is that feasible?

Also, are some techniques more amenable to cross-platform determinism while others are more challenging?

Note that Rapier can do this for mechanical simulations aimed at gamedev https://rapier.rs/docs/user_guides/rust/determinism/

Moreover: can I add threads or use SIMD or run on GPUs and still be deterministic? (Rapier can't do that: it runs on CPU, and on the cross-platform deterministic mode it disables threads and SIMD)

I'm not sure if those are considered worthwhile research lines, but this is what I care most.


The most recent Times Higher Ed world university rankings for Computer Science put Toronto at 17, Waterloo at 23. The QS rankings give Toronto 11, Waterloo 26. You can debate the merit of rankings, but there's simply no credible way to argue that a school that routinely appears in in the world's top 30 is "mediocre/trash".

Relatedly, Waterloo is in fact included in the Budget 2017 funding for Canada's overall AI initiative, of which this Vector stuff is a part:

"In this budget, the government announced the creation of the Pan-Canadian Artificial Intelligence Strategy, which will promote collaboration between AI hubs Toronto, Kitchener-Waterloo, Montreal, and Edmonton. It will be dedicating $125 million towards the launch of this strategy."


This is just concern trolling. Obviously all these issues are important to address; simply pointing to another issue does not contribute to solving either of them.


>concern trolling

Thanks, I was looking for a way to call people disingenuous without actually using the term, since it's apparently become a no-no word on HN.


You can come do a PhD with me at Waterloo. #shamelessplug https://cs.uwaterloo.ca/~c2batty/


Small world! I actually am majoring in comp sci and physics. I'll definitely message you if I end up getting into research next year.


Yes, there is a fair amount of similarly and connection in the underlying mesh data structure. In fact, we published a paper on that aspect of the framework at SIGGRAPH a couple years back, which heavily cites the Surface Evolver work. http://www.cs.columbia.edu/cg/multitracker/


Thanks! At this point, since this is really the first version of a new and different technique than is typical in graphics, the method is not near real-time. As you suggest, the offline setting is probably the most relevant for now. We are hopeful that future research may substantially accelerate it.
