This looks like the new Google Lively.

And no one will use it.

codesushi42··on Voidcall – Making of 13kb JavaScript RTS Game
Excellent post, thanks for sharing. You may want to read up on influence maps if you want to improve the AI.

Also you should check out a book called Programming an RTS Game with Direct3D if you can find a copy: https://www.amazon.com/dp/1584504986/ref=cm_sw_r_cp_apa_i_BQ...

codesushi42··on Claude Shannon, the Las Vegas Shark (2017)
It is really Edward Thorp who was the shark. He was the one who pitched the idea to Shannon of building the first wearable computer to beat roulette. Shannon was not very much interested in talking to Thorp until he proposed the idea face to face.

Ed Thorp is still alive and has written some interesting biographies. Check out A Man for All Markets if you are interested. The Physics of Wall Street is also a good overview of quantitative financial analysis.

codesushi42··on A Eulogy for Objective-C (2015)
Because otherwise the struct will be copied when the function is called.

Though your question is kind of getting at r-values and move semantics, which is a solution to prevent copying the temp value both when calling the function and in its execution. You can read about it because it will take too long to explain it here.

codesushi42··on WeWork’s Adam Neumann Steps Down as CEO
We need an HN thread that highlights companies to never work for and why, like this example. Thank you sir.
codesushi42··on WeWork’s Adam Neumann Steps Down as CEO
Facebook is one, and a week doesn't go by without me being contacted by one of their recruiters touting their advancements in poker playing AI. Whoopee.
codesushi42··on OSSU: A path to a free self-taught education in computer science
This is very interesting. Is this an online Masters or is it a free program?
codesushi42··on OSSU: A path to a free self-taught education in computer science
Yes, I did Discrete Math long ago and enjoyed it.

Thanks for the link! Though it looks too basic for me, I was hoping for something on the more advanced topics I mentioned.

codesushi42··on WeWork’s Adam Neumann Steps Down as CEO
That is interesting. Were you around in the dotcom days?
codesushi42··on OSSU: A path to a free self-taught education in computer science
Also a request for any resources of scientists trying to get their head around how to write good software, we're all pretty much people who once read a C++ tutorial and just went with it.

That is an interesting question I had not thought of. I genuinely cannot think of a single resource that teaches good software engineering practices, like how to structure code in a robust and maintainable way. In fact, many books that I read usually include examples using terrible coding practices. And then the ones dedicated to software engineering are usually too out of date or academic (GoF, Fowler books).

I would say read up on inversion of control and dependency injection. And then a book on unit testing. Writing your APIs to use dependency injection and making them easily testable (by testing output not internal state) gets you most of the way there.

codesushi42··on OSSU: A path to a free self-taught education in computer science
Does anyone have a similar resource for applied math?

I am looking for something that goes beyond the standard calculus, linear algebra and stats material. For example, optimization, numerical analysis, stochastic processes, dynamical systems etc.

codesushi42··on WeWork’s Adam Neumann Steps Down as CEO
Same here, and only by reading the headlines. A WeWork recruiter reached out to me. I laughed out loud and added it to the list of companies I would never work for. Not only do they do nothing interesting, but they are apparently unethical as well.

No doubt another failed tech bro pump 'n dump scheme headed to the dustbin of history.

codesushi42··on CHP Arrests Driver Impersonating Chinese Paramilitary Police
Being shot on US soil by a Chinese policeman operating as one would constitute an act of war.

Just saying.

codesushi42··on The BeagleBone AI is Available
You can get a good, stable model on less training data, which is great when your training data is expensive to produce

Huh? SVMs don't perform better than NNs on less training data.

I'm sorry, but the rest of what you said is out of date and wrong. CNNs work better than SVMs for CV tasks. There's no reason to use SVMs anymore for CV, and no one in their right mind does.

codesushi42··on CHP Arrests Driver Impersonating Chinese Paramilitary Police
I don't know.

But it makes me feel better about the second amendment.

codesushi42··on The BeagleBone AI is Available
Ok, what you said about lower res images makes sense. Lower variation of images maybe means you could get away with less weights/more quantization-- you could afford to lose more information in the model. Maybe 1GB can be sufficient then.

There's no reason to use an SVM over a (C)NN nowadays though.

codesushi42··on The BeagleBone AI is Available
That reasoning is just plain wrong. The memory usage has almost nothing to do with the field where it will be used. It will depend on the size of the model being run on the board.

The size of that model will be determined by the number of weights used. Being that industrial automation will likely use CV, that will mean the potential for a lot of weights.

Same goes for any other non trivial use case.

So yeah, 1GB is paltry.

codesushi42··on Lectures in Quantitative Economics with Python [pdf]
Was it? Because I have no clue what the poster was referring to.

And economists have been writing code since PL/1.

codesushi42··on Lectures in Quantitative Economics with Python [pdf]
Which ideas from CS?

You mean optimization techniques that don't work in the real world of finance?

codesushi42··on Hard Times in Silicon Valley? Not for the Payments Startup Stripe
Google was founded right before the dotcom bubble burst.

Yeah, we are still headed for a downturn/correction/crash or what have you.

But valuable companies will continue to be.

codesushi42··on Books on Burnout
Two years is not that long.

Power through it.

codesushi42··on Books on Burnout
And your response isn't? And who is to say it's wrong?
codesushi42··on Books on Burnout
Here is a hint:

Stop working so fucking hard on apps/websites/digital junk that helps no one, except by making your boss rich (be it manager, VC, or otherwise).

If you engage in meaningful work, then it is impossible to get burned out for too long.

Stop being a drone. Take a step back and look at the big picture and ask yourself: what am I coding for? Who is going to use this? Will it help anyone in any meaningful way?

What is "meaningful" is up to you. Just make sure it matters to you and own it. Don't let someone else own it and dictate it to you.

Set yourself free, and cast off the 24/7 toxic work culture of SV that's keen on producing useless shit for problems no one has. Don't let yourself be consumed by the entropy emamanting from startup land. You don't have much time on Earth. Don't give it to unworthy efforts and assholes.

codesushi42··on Silicon Valley is terrified of California’s privacy law
What will these laws accomplish in real terms?

This just seems like poorly written legislation with the purpose of pandering to the populist public. I guess if it makes you all at least feel better.

This is exactly the type of answer I was looking for. Thank you sir.

LMAO

I just... I can't.

codesushi42··on T. Boone Pickens Farewell Letter
Don't come here for the political commentary. Do it for the technical commentary. At least when it is not completely incorrect bullshit.

But the latter has always been an issue here. And there's still enough insight to keep me coming back.
