That's super cool; would you mind sharing your folder?

I am wondering if engineering simulations for fluids take advantage of GPUs? I studied CFD back in 2005 or so and we used ANSYS Fluent as a solver and it took forever to converge with sufficient accuracy.

If anyone in engineering has insight into this, I'd love to know.

Technically, non-fluid simulations could also be sped up using GPUs? Dynamics, solid state mechanics, thermal simulations, etc.

I couldn't disagree with you more. Everyday, I read articles about VC. How to pitch, how to prepare, how to strategize a startup to ensure future growth, scalability, etc.

Let's just take an article from our own backyard: https://blog.ycombinator.com/ycs-essential-startup-advice/

Almost 800 points on HN: https://news.ycombinator.com/item?id=15331016

Quoting the article, "Growth is always a focus for startups, since a startup without growth is usually a failure." This is article doesn't apply to folks who want to stay small (the discussion of this topic ~ 3 people company).

You could have approached your argument a little less strongly - simply stating your opinions. Authoritative didactic statements require data to back it up otherwise it just sounds abrasive and completely unproductive.

I found your comment a bit abrasive, yet you’re lacking the grit to support it besides just anecdotal evidence (just as the parent comment).

I have yet another opinion - I’ve seen a wide variety of articles on HN from how to grow fast to how to stay small. We’re not going to stay productive by arguing without data.

You seriously can’t tell it’s a AR/VR headset by looking at a guy wearing glasses with two wires coming out of it?

You may not know what MagicLeap - the company - is, but you certainly don’t need to be told it’s a AR/VR headset.

I agree with obscure random crap that shows up on HN and takes forever to figure out what it is. This isn’t one of those cases. It’s utterly obvious.

This kind of thing drives me crazy! But, for a small project that’s not obvious to anyone - this makes sense.

Look at Apple’s full iPhone landing page. It’d be silly to explain at the top “iPhone is a wireless digital communication device.” It’s obvious that dude is wearing glasses that look like AR/VR headset. You ain’t gotta spell it out for people.

Thank you, absolutely fascinating talk. It was hard to develop video games back in the day and just as it was hard to beat those games. What a wonderful era of ingenuity, creativity and passion.

No one is talking about resume. I’m talking about his approach.

If I see this kind of resume land or my desk, it gets thrown out.

I found his approach tacky, loud and insincere.

Of course you should be talking about yourself on your resume but a couple of this that are different here:

- Wtf is up with music - 51%/49% thing. - Publicly asking to be hired that reflects poorly on his current job at Google. - Excessively loud self marketing

why not have a simple site with your accomplishments? Why all the excess bullshit?

Checking his website, it reeks of narcissism. There are better ways to assert yourself than to do all the corny things he has done on his self promotion website.

Do you have any examples of "You might get sued for this"?

Calling $16k on a security that is amidst an explosive growth is hardly insightful.

“If some listened they might have made some profit” - I think you’re giving yourself too much credit here.

Also don’t forget - we still have to write certain routines in Assembly even after so many years. Number of abstraction layers doesn’t mean complete automation.

I do not recommend this. See my comment above.

I don't recommend ContextualElectronics.

It is not even good for beginners as so many things he does is completely and utterly wrong. People who do not have the expertise in their domain should not be teaching and perpetuating wrong methods and creating a generation of bad engineers/makers.

If you get a chance, please watch his YT series on KiCAD. Finally, he gets a PCB made and fumbles his way through.

Teachers are supposed to be domain experts that can lead students in the best-known-method path. This guy doesn't even come close.

If you want solid tutorials on Embedded Electronics, I recommend Patrick Hood Daniel's Newbiehack channel.

Not only does it skip the Arduino framework, he goes to a great length to explain fundamentals of embedded electronics. He is a fantastic teacher and above all, an expert at what he does.

That is ridiculous. Electronic music production is a completely separate market.

I see this in Art all the time.

Ever read a description or a brochure for an art show? An artists' biography?

It is full of infuriating bullshit.

It was so refreshing to read Francis Bacon's newly released Catalog Raisonne. All descriptions and biographical information is factual without any discussion of some pseudo-profound meaning. Same goes for good art critics such as David Sylvester[1]. He was one of the very few art critics that tried go past the pseudo-intellectual bullshit and truly understand Art and the Artist behind it.

I have read dozens if not hundreds of art catalogs, brochures and biographies. As an objective person, it is so difficult to get past the bullshit to actually understand and approach art.

I went to Georgia Tech and took the Renassaince Art course. About 98% was bullshit to the point I thought that it was some kind of a joke. I couldn't believe it.

If all inputs are in hh:mm format, then there is no ambiguity of 930 as 9:30 am/pm. There could be a toggle for AM/PM.

Who puts seconds as an input for setting their morning alarm? MAD!

Intel has a big assembly site there (Chengdu, China) but fabs are still in the US, Israel, Ireland.

I wonder what Trump has to say about this move by Elon.

Redditization of HN, ladies and gentlemen. Jokes/Puns will ruin this place.

HN's design is utilitarian. 100% business. 0% party.

I LOVE HN's design.

You seem to have a really good understanding of this topic. In your view, what do you think the definition of UX, UI and graphics design is? I think that would be beneficial to the readers of your comment.

Also, can you cite some examples of the list of products?

I can think of

- products with great UIs and awesome graphic design but horrible UX: Shopping cart checkouts that if you click something, you have to write the CC/Name-details again. Multi-city flight search on any major travel site is a pain in the ass.

I hate to point it out but HN is not for jokes/puns. Please go to Reddit for that. Thanks.

I wrote a library for Java/Processing that resonates with this article:

https://github.com/neilpanchal/Chroma

That was painful. It is one of those things that you can't just stop watching (I was expecting Sally to spin the salad) and I waited..and waited...waited.

Horrible user experience.

  - Can't tell how long the clip/gif is
  - Can't skip ahead
  - Can't go fullscreen
  - No sound

WTF.

I know what you're saying - I've done a few of his exercises and using the iPad app makes that very easy to do. Literally, simulates the same experience of getting the $200 edition with all the color plates. Drag a shape over another and see the effect.

Color is relative. Got it. What else does it offer?

>> The book is not supposed to be about “scientific progress”. It’s supposed to be a pedagogical tool aimed at artists. If you want a technical explanation, you are looking at the wrong book.

I understand and I wish that was the case! However, the popularity of it and its fame as a text book (see Amazon reviews) combined with his claims of explaining how brain perceives color - indicates that it is used as THE color theory reference. I have a problem with that.

Thanks. This looks extremely interesting.

I read Josef Albers' Interaction of Color years ago and I've also bought the iPad app. I've been disappointed by both.

The problem is that "experiential" teaching without any scientific explanation is inadequate and misleading. Teaching part is where you explain the students - why. It is perhaps the approach in art colleges where rigorous science doesn't matter.

The problem stems when Josef Albers made scientific claims which go unquestioned as the factual basis for his cool color experiments. That is wrong and that's exactly the kind of nitpicking we need to do. What you call 'Pedantic nitpicking' is necessary and essential to the scientific process.

It is rather misleading to start the book with "The book does not begin with optics and physiology of visual perception, nor with any presentation of the physics of light and wavelength…. What counts here—first and last—is not so-called knowledge of so-called facts, but vision—seeing." and then go on to explaining his experiments using false claims (which again are highlighted and detailed in Alan Lee's criticism).

Anyhow, even if I am considering Josef's Interaction of Color from an artistic standpoint, he simply points out the cool illusions without any follow up on how to use/implement his concepts. I find it as a casual book that sits on the coffee table, not on my work desk.

The problem isn't that he used color to make interesting new art. I think he explored new areas of color which were not known before - and I applaud his artistic efforts.

However, Josef Albers went beyond his art to make false claims about color theory, how the human brain perceives color and made broad generalizations - based on anecdotal evidence and intuition. He went unchallenged for the most part. See the criticism linked in my original post.

I just checked the book "Color for the Sciences" that you had mentioned. I think I am going to purchase this one! Thanks.

Edwin Land also made tremendous contributions to color science through empirical measurements and finding the deeper "mathematical" models[1]. Besides his scientific achievements, he was a real renaissance man, a tour de force of human intellect. Unfortunately, Josef Albers's pseudoscience[2] and artistic non-sense get most of the credit[3] when it comes to color theory.
