For charging overnight, my concern is that (A) if drive very much during the day and (B) the house has only a 100 A circuit breaker box, then the charging time will still be too long, that is, that overnight is not long enough. The back of

I can accept Newton's second law of motion and Einstein's general relativity, but so far I'm less accepting of deep learning for finding some coefficients for fitting some data or neural networks for fitting some sigmoid

Sure, the grid can provide the power for fast charging, but charging a battery heats the battery, and charging it too fast heats it too much. That's my concern. If Tesla can make the charging time short enough to be convenient enough

To give a meaningful answer, I'd need a more detailed question.

Moreover, they are not going to invest in a $20,000 seed round. They will say that it won't "move the needle". Well, for their 2 and 20, they are correct. For exit value, they can be wildly wrong.

Right. My guess is that the tune is called by the limited partners who are much more comfortable investing in growth capital.
1927.
by graycat 10y ago
I can say with high confidence that there is not even one venture capital person in the US who would invest even 10 cents in my work, call it AI or not, before they see usage significant and growing rapidly, and then they are not investing

Yup. But it may be that some people with enough information and time to watch the stock and relevant data on it literally second by second could make a killing. And some people might be in a position to influence the time of the turning

Sounds like a good short selling opportunity.

Yup, we've had several AI winters . Now we have an AI Spring of Hype. Then we will have a Summer of Hope. Then a Fall of Failure. Then another, long AI Winter.
1931.
by graycat 10y ago
From all I can see, nearly all the present AI boils down to one word -- hype. From what is really going on, nearly all of it looks like (1) in some cases a lot of new data, (2) some new, faster processor hardware, e.g., based on graphical p

IMHO, for professional investors , the "significant progress* is judged by traction as I described. Then, for a Web site startup, traction means users and ad revenue, and quickly a sole founder is nicely profitable with cash enough

A BoD usually means a Delaware C corporation, and that usually has some lawyer expenses. May have some founder employee agreements for some more lawyer expenses. And there may be insurance for the board members, e.g., as at https:/&

by graycat 10y ago
Right. I was assuming a sole founder and not hiring anyone. Or some dedicated co-founders doing what you suggested.

Yes, all nice data, but $400,000 is, sorry 'bout that, no matter what it's called, is not appropriately called a seed round. Let me guess: The usual criteria are all the first technical work done, traction significant, and t

I remember a lot that was "good or unique": Prime was a cheap Multics complete with processor security rings, gate segments for user programs to call into the OS, an hierarchical file system, and capabilities and attribute control
1937.
by graycat 10y ago
The first versions of Primos were written in a slightly tweaked Fortran. The PL/I role was significant but later. I managed a Prime system when I was in grad school and later lead an effort to get a later Prime system when I was a B-s

Knowing Cobol, Algol, Fortran, APL, Lisp, PL/I, several assembler languages, several scripting languages, etc., actually, maybe surprisingly, does not damage the brain! There is a lot in, say, PL/I that should be in more recent la

Why? Hiring manager A doesn't want subordinate employee B who knows more about the work of A than A does, or is better at office politics, meeting customers, managing people, etc. Or, manager A wants only subordinates (secondary, su

Over fitting can, indeed, be "fitting the data too perfectly"; e.g., Lagrangian interpolation where have some X-Y pairs and want a polynomial in x that fits the X-Y pairs. How does that work? You can derive it for yourself:

For your > will be a panacea to that which ails the middle class. IIRC, Trump's campaign statement was "Jobs, Jobs, Jobs." Each time I heard him say that, I wondered, what kind of jobs, for how much money? All I could thi

With the main issues in the OP, I have struggled for too many years, and I strongly agree that the main issues are very important. While the OP makes some solid points, mostly I disagree with the essay as a whole. I got into math because (A

Ah, you got me! I know the Roman alphabet, but I know only a few letters from the Greek alphabet, a few I picked up in math and physics. When I type in math, say, into TeX, sometimes I use some Greek letters, but I use only the ones that

Your first icon looks like truck with a tank carrying some liquid, maybe water. The second one looks like a net for catching butterflies. For both, I wouldn't know the context.

For stop signs, restroom signs, etc. I agree. But here I am talking about the subject of the OP, Web page design. Yes, I have finally learned what the icons from Adobe's Acrobat PDF viewer and my favorite Web browsers do, but those ar

Sure, he's correct -- if and only if make a lot of assumptions. But he is talking about startups, and there, from all I can see and without his many assumptions, a Delaware C-Corp is a lot more time, lawyer money, other overhead, and b

There should be better ways to know how to "value an idea.". I believe that there are better ways, that the VC-startup world does poorly there with biggie costs on the both sides of the table, that there are some good examples of

From about 20,000 feet higher than the OP, one of the issues about PG, Sam, and YC is the combination of (1) lots of warnings about the dangers of disputes among startup co-founders and, thus, the extreme need for yet another startup co-fou

IIRC there was a claim that the shells with the proximity fuses were also used, likely by Patton's forces, in the Battle of the Bulge. Supposedly having the shells explode at a carefully determined distance above the ground made the s
