solinent··on A new replication crisis: Research that is less likely to be true is cited more
What is the likelihood of this study being true? Will it be cited a lot now?
solinent··on Ask HN: Who wants to be hired? (March 2021)
Location: Canada

Remote: Yes

Willing to relocate: Yes (Canadian citizen)

Technologies: C++/C#/Java/Haskell/Python/JS/OpenGL/Vue/Flask/Qt/Houdini

I have a mathematics degree from Waterloo, where I was employed through their co-op program for two years as a 3D graphics developer for SideFX's Houdini, working on the 3D viewport. I then moved into augmented virtual reality (as we called it), researching developing mapping systems for a company which sold to Facebook, Sulon technologies. After that I worked for Teledyne Optech, the leading Lidar company, developing their mapping suite software. At the present I am working on building a startup developing an analytics suite software using NLP for M&A law firms. Ideally I would find some part-time remote work (30 hours is still okay) so I can continue with my business, but I am willing to cut my losses given the right opportunity. Thanks!

solinent··on Launch HN: Xix.ai (YC W17) – Securely authenticate in web apps by face
Your face is not really a secret, hardly very secure, I'd say.
solinent··on The decline of computers as a general-purpose technology
I think as computers fail to get faster, we won't be able to improve performance without making application specific logical units, however, we may still be able to make it general purpose.
solinent··on What working in an Antarctic station taught a researcher about isolation
Isolation by itself can come in many different forms, I'd say. I don't think that all of these metal diagnoses due to isolation really apply to everyone or every situation very well. It's important to consider that some people historically lived very isolated and also some people lived in the middle of civilization, and some did both.
solinent··on When Everyone’s a Genius: A Few Thoughts on Speculation
Diversify your speculation, I think that's the best advice, and make sure you stay grounded, ie. have a base which won't really move much relative to potential hyper-inflation.
solinent··on Facebook says it will pay news industry $1B over 3 years
I think that's an absolutely terrible idea.
solinent··on Noise pollution hurts the heart
It's really more about signal-to-noise ratio I'd say, if there are often loud noises then your brain will have to attend to them, if there is constantly a fan noise, for example, then your brain will actually focus since there is no signal--but I've definitely found it's best to get rid of both in almost all domains.
solinent··on Ask HN: Is it crazy that software developers have to study for interviews?
If you have to study for the interview, they're not selecting their candidates for intelligence, really, but either intelligence or studiousness.
solinent··on Kanban board in one HTML using localstorage
Maybe I'll take a shot at a very simple backend, I've not been able to find a kanban which is simple enough for me.
solinent··on Threadripper 3990X: The Quest To Compile 1B Lines Of C++ On 64 Cores
> 1B Lines of C++

Seems like our code is inflating quite rapidly. I remember when 1M was the biggest project. /snark

solinent··on Deep neck flexor exercises – Back and neck
Another in addition to these excellent suggestions would be scapular pullups and scapular pushups.
solinent··on To the moon: defining and detecting cryptocurrency pump-and-dumps (2018)
It seems to me the investment community has accepted bitcoin at this point, with major institutional investors finally buying in now--1 billion from microstrategy, for example--so expect to see it go up more. I think it will keep going up until it gets regulated, I'm sure they'll continue to find ways to "increase liquidity" despite Bitcoin.
solinent··on Pixar's Render Farm
Definitely--lots of old assets are used for testing, I've seen them personally. It's standard practice to keep around old models, scenes, textures, etc.
solinent··on Pixar's Render Farm
They render them at a very high resolution, so perhaps the person I heard the rumors from was talking about reducing the resolution to something less than 10k by 10k (or more sometimes, I've been out of the film industry for 8 years).

I shouldn't really say more.

solinent··on Pixar's Render Farm
I've heard rumors that Pixar used to be able to render their movies in real-time :)
solinent··on Meals based on vegetable protein sources (beans and peas) are more satiating (2016)
I should have said gut--I've been calling my gut my stomach for too long and have had difficulty stopping that habit.

However, I don't think we really know where satiety comes from yet, that's why we have all of this research on the topic still. There are a few different theories, but I wouldn't call them proven.

It may not be a sensation related to some measure of the volume of matter in your gut. I think it's also related to gut microfauna such as lactobacilla, and appetite is definitely related to the brain as well through the gut, so it probably gets pretty complicated and possibly is very individualized. I'm no expert, but I do read a lot about these topics.

solinent··on Meals based on vegetable protein sources (beans and peas) are more satiating (2016)
I think it's related to the fermentation going on in your stomach. I'm not sure if it's the best way to become satiated.

I personally find saturated fats to be much more satiating, I can go without food for a full day without feeling hungry if I eat enough.

solinent··on A Generative Grammar for Jazz Chord Sequences (1984)
I'm a jazz musician--it's interesting stuff, there is a whole area of research dedicated to this type of work.

Jazz chord progressions are pretty simple ultimately when expressed in compressed form, but tend to have actual semantics behind them be pretty communicative so I doubt this will cover absolutely everything except the popular works.

You can generate something very close using a formal grammar but you get stuck in the same position as the logicians in Chomsky's time. I've had some really great thoughts about ML approaches, however, with some sort of seq-to-seq approach.

solinent··on Leaked documents from Nintendo investigation of hacker in 2013
Nintendo is a pretty interesting company, the stories I have heard are completely the opposite of the colorful friendly reality they paint on the outside. Maybe it's because of how ruthless they are that they are able to do it--I wouldn't know, no one told me.
solinent··on Facebook being investigated in Germany for tying Oculus use to Facebook accounts
We need to allow multiple app stores with DRM per store, it's the only solution to avoid a monopolistic store that I see. It won't happen except through the legal system, I think.
solinent··on Pfizer chairman: We're not sure if someone can transmit Covid after vaccination
I have no clue, I'm not an expert. I just don't see any discussion on this topic and it concerns me. Historically, I don't see any vaccine which was effective against such a virulent virus, unless it had a much higher rate of immunity. I'd gamble on 5% odds if the reward was high enough, so 95% immunity sounds good but it's only half as strong 97.5% immunity, for example.

I do know that the immunity may only be temporary--1 out of 20 cases of the most virulent strains may then have a larger substrate to mutate within, but I'm not sure if you can get many strains at once, for example. I do know that the flu mutates each year, and I guess I'm basing this whole "increased selection pressure could cause more mutations" on that fact. When there is less available space for the virus to propagate, it's only chance of survival is to be able to infect those who are already immune.

In my opinion, we have an immune system crisis here--we need to focus on eating better and exercising more: we have to fight this virus with every tool we've got, but if we wait a few more months it's possible that we'll get a stronger vaccine. I suspect that's why it ended sooner in certain places--I doubt any measure we can take have had any real effect due to the virulence of COVID--it's in the air and on surfaces and lives there for days, and is transmitted by asymptomatic carriers--so your uber eats driver driving in their car with the AC will infect your food etc.

solinent··on No One Wants Used Clothes Anymore (2018)
My loose clothes become my pajamas eventually. If I gain weight, the tightness serves as a reminder for me to lose it again!
solinent··on Pfizer chairman: We're not sure if someone can transmit Covid after vaccination
I hate to be that person, but I'm personally more worried about the virus mutating under the increased selection pressure. We only defeated polio with a >99% effective vaccine, and the research for this vaccine isn't even available.
solinent··on Notation as a Tool of Thought
I'm a bit of both, so I guess I take the radical approach--straight from mathematics to C++/ASM/FPGA/ASIC. Ultimately programming languages are just an alternate notative system for mathematics--formal language theory actually formalizes and generalizes this, it's what us Computer Scientist's specialize in generally.

Since the computer is just a glorified calculator with memory (sorry Apple), we can fit the whole thing into a formal mathematical framework.

solinent··on Compound found in the hallucinogenic tea ayahuasca can grow new brain cells
It gives you a new perspective, but for some it can be traumatizing. I think it's a much better treatment than any drug out there, though, so maybe it has a potential to be integrated into our culture.

Environment seems to be the biggest factor in any successful treatment--drugs, psychedelics, or nothing at all--environment reigns supreme.

solinent··on Notation as a Tool of Thought
There's a certain mathematical elegance to APL, I think. When the language is terse enough it helps you visualize and work with the language as a tool of thought--Matlab attempts to map actual mathematics to ASCII which is not that successful for me at least, since it meets a middle ground where it's too difficult for me to think quickly purely in Matlab and it's too high level for it to be useful as a practical language.

Engineers love it for prototyping, though, so maybe I just haven't worked with Matlab enough.

solinent··on Contemplating the End of Physics
This is exactly what we thought before Einstein came along and disrupted the whole scene.
solinent··on hCaptcha now runs on fifteen percent of the internet
While privacy is definitely my main concern here, it's not just privacy that's the issue here--I believe people should be compensated for the work that they offer society and if Google is using a captcha to create driverless cars then it's obviously antithetical to this premise.

I always try to miss some of the obvious items or make mistakes and I (almost) always get through. There's only one service that uses a Google captcha that I continue to use, so it's not really a huge issue for me anyways, and I have decided to stop using it!

It's not too difficult to host your own captcha, I don't see why this can't be an open-source effort.[1]

solinent··on macOS has checked app signatures online for over 2 years
It's possible that the technical discussion about online signature checking was subsumed by the political discussion--the two are interrelated and if we don't get into these discussions here I don't really see another place for them to happen.

It's easy to shrug it off as simply a technical issue, and it's very convenient for the PR department as well.
