Yeah, I was pretty upset at this, too. In high school, I was taught a very washed-down form of linear algebra (very basic vector and matrix operations), and then in uni, calculus and linear algebra were taught at the same time. I made up for it pretty much by going over a linear algebra textbook all by myself, again, in my 3rd year of university.

I get to use Calculus pretty often because I regularly do both hardware and software work (perks of having an EE degree; according to my diploma, I'm an intruder and should not be allowed to touch computers :-) ). Analog systems have continuous-valued inputs and outputs and you can't really describe those without Calc, and in mixed-signal systems you often describe various properties of the discrete signals by starting from their continuous counterpart.

> Any pointers on who might be a good VC outfit for SaaS type startup that actually needs to run their own clusters as opposed to throwing everything onto AWS?

Very curious, why do you think you need to run your own clusters, to the point where you think you need to seek unusually risk prone capital?

If your justification is that you are are optimizing for cost (e.g. maximizing your performance per dollar), then you must think the capex dramatically lowers opex at scale if you move from AWS to specialized hardware (say, an FPGA bare metal cluster instead of a GPU or CPU cluster in AWS). In such a case I would argue that you should just get enough paying customers first using AWS, to build up enough cash-flow that would then clearly justify the capex for scaling up and going colo. And at that point, you would not need to shop around for wild risk taking capital, the CBA could easily be explained to any VC and in fact you could probably even just get a bank loan to finance the capex if it is a clear winner in reducing costs.

The only scenario I can see where you really need to run your own hardware from day 1 is if you need to terminate some dedicated circuits for specialized data feeds (e.g. real-time market data)... In that scenario, I would recommend looking into co-locating the data appliance in a third-party data center that is physically nearby to US-EAST and can run a Direct Connection into AWS for you.

Otherwise, you may want to consider the possibility that your desire to own your own cluster may be a case of premature optimization and scaling up too early/too fast. It's a very expensive thing to do and an easy way to accidentally run out of money if you don't have client contracts signed beforehand.

Here's a several billion dollar hard tech idea that would benefit many, many, many people: cheap/fast/efficient water desalination and purification. It's a hard problem. Current solutions aren't cutting it.

Unlock water from the oceans, and a lot of people can be helped. I'm ready to start this company, just need a few dozen engineers/chemists and a boatload of funding.

This is probably the reason why there are so many more autodidact programmers than mathematicians. When programming, you know if you made an error as soon as you try to run your code. The program, by definition, must be "correct" in order to execute. The "source of correction" is the error detection built into any programming language runtime or compiler.

No such "source of correction" exists for mathematics, and that makes it an inherently more difficult subject to teach yourself, because any errors you make will "fail silently" unless you are capable of detecting them yourself, which by definition you cannot do without experience. This is why a mentor/professor makes learning mathematics so much easier; he/she plays the role of mathematical compiler.

The implementation felt like they'd asked a VB6 dabbler to implement it in Java. Then stuck it in the cheapest 600mhz tablet they could find.

The UI was purely a button grid with distorted graphics, and dodgy typography. Button presses took about 1/2 a second to respond, and every 5th press caused the app to crash (adding a good 30 s to the experience).

My room had 4 tablets* in, and all of them behaved exactly the same way.

As an amateur inventor with a serious backlog of "hard tech" type inventions (e.g. actual products, not software or 'platforms') I've done my best to inquire and reach out to several different potential funding sources, all of which have been extremely quick to pass. The basic reasoning is "this doesn't fit with our preferred verticals" and I'm left to figure out what that meant other than We only speak app as a self-imagined consolation.

This article is not exactly re-assuring because the noted interests - AI, biotech, and energy - are all extremely crowded fields more than likely competing with large institutions, research organizations, and let's be honest, probably a TON of regulatory hurdles to consider if planning to do business in the US.

For context, one of my primary inventions is a mobility / utility device that would have residential, commerical, and industrial applications. By design it can be applied to a variety of uses. I've done basic patent research and the pathway looks extremely good, quite tempting for me to just go ahead and file ASAP. It's hard tech. It's not glamorous, but it's a huge market opportunity on prima face.

I've got a co-worker pal who finally got his beverage and branding invention patented and now he's in the marketing to local schools, catalogs, and if early indications are correct, he may have an genuinely lucrative future with it. In my view, he's a more likely investor target than anybody out on the West Coast or in a VC room. I simply base this perspective on personal experience and how this post sounds promising yet concludes with a short list of massive goals. Might as well wrap it up with "We just want to invest in a better mousetrap" considering the scope. Cottage industry isn't runaway freight train profit creation, I get that, but I'd also counter that if one wants to get into the next frothy bubble of biotech then good luck with that.

Well written and mostly agreeable but I've got a lowbrow dismissal incoming: I disagree that Cruise could be considered hard tech. The hard tech in that space was done by universities competing for DARPA awards, and Google after that. Cruise took inaccessible hard tech and made it more accessible.

And that isn't an insult to Cruise. The problem space is still difficult, and they created more value tackling that than the vast majority of startups do on much easier problems. I happen to think that the opportunities for making the cutting edge more accessible vastly outweigh the opportunities for cutting new edges, and nobody should be discouraged from doing it because it isn't as glamorous as the research on the ground floor.
An open letter to Quora
Does this help any? Say we're looking at a grayscale image, where each pixel has a value between 0.0 and (just less than) 1.0. Sort all the pixel values, then scan them from lowest value to highest. The pixels with the lowest value in the image get reassigned the value 0; and in general, a pixel that's brighter than k of the other pixels, out of n total, gets changed to intensity k/n. This spreads the intensities as evenly as we can. (Which might not be so even, for example if all of the input pixels were the same intensity to start -- then this just changes them to 0!)

Maybe the image is, say, 8-bit grayscale, so the values can range from 0 to 255 instead -- then it'd be floor(k/n times 256).

This is usually described in terms of a cumulative description function; I tried to say the same with less jargon.

Be careful with "lack of competition". You are ALWAYS competing with the incumbent solution. No matter how clumsy or awkward it seems; no matter how much better it could be; those solutions have amazing staying power and your niche can become your enemy because there's a limit universe of customers to sell the solution to.
Same here. It's probably a hard coded message. You'd think the hacker news post would skew it a bit if it was realtime. Either that or they have a really massive data set on it that's hard to skew.
On the most recent iPhone, data isn't encrypted based on a 4 digit PIN. It uses a tremendously long piece of data as the encryption key, but the encryption key is only accessible through some special hardware they have (which is essentially tamper proof and brute-force proof) with the 4 digit PIN. But as you said, since they can remotely update the software for this special piece of hardware, it is still susceptible to being compromised.

A lot of the conversation happening in regards to this FBI case is only due to it being an older iPhone that doesn't have this special hardware. Which is why people are confused with the FBI chose this case as their poster child when it would have made a lot more sense with the most recent iPhone.

Here is my serious question for Hacker News community: who the upvote this piece of ? I mean, seriously, guys, why, in the name of all that is (even if marginally) correct, did you up vote this piece of fantasy?

I frankly don't think this piece of deserve any more attention than the few minutes I spent insulting it, but I think my insults require defense. After all, they are probably less trashy than their target (in this case; note: I am generally against insult; but guys, I can't help myself). Here goes the defense (feel free to ignore it; again, just ignore this whole things to save yourself a few precious minutes):
1. Gold is among the most useful material on earth. It is impervious to any kind of oxidization, as well as soft and easy to work with, plus conducts heat and electricity superbly. This means that even the least developed societies can fashion high quality tools out of it (from bowls to utensils to weapon). The idea that somehow gold is useless (beside decoration) is beyond laughable.
2. Secondly, the idea of rich and poor within a lowly bartering-only society is also laughable (well, this one is slightly less obvious than the uselessness of gold). Wealth implies accumulation, which implies settlement, which implies (relatively) high food production capacity. By then, oops, you are talking about relatively advanced societies. There is one thing I have yet to find: a society with wealth that looks at gold with no more than amusement.

So, 1+2 means that a place where rich people only employ gold for decoration is a fantasy by idiots. Again, I am against name-calling, but this is just so.... Sorry, my bad. Anyhow, please save yourself and STOP UPVOTING IDIOCY.
Maybe more plausible when it's the core talent + specific tech applicable to the problem?

You're buying both a base platform / proof of concept+ implementation and the key individuals responsible for creating it. Then training your people on the platform with the deeper knowledge from the key individuals in the 1-2 years you've got them employed.

If you can buy a breakthrough and enough knowledge transfer to get your people operational on adapting it, it's worth it even if you don't get any additional breakthroughs?
If nearly all cars available had a faulty breaking system, would you swear off cars altogether or would you keep looking for one with it fixed?
That helps but you have to understand that most industrial and utilities sites hate new tech. They like proven tech that's been used in three other places before they adopt anything. And once they settle on something they want to stick with it for 15-30 years and have support for longer because everyone knows that it's going to take another 3 years to get approval for purchase of new components because the old stuff has been giving faulty readings the past year and a half which requires hard reboots, the firmware is no longer being upgraded and the guys who first used the stuff are starting to retire. Even then they just want something that fits into the same slot.

Sorry for the runon but this is a major gripe of mine. Most managers just want it to work and unless it doubles your profit, cuts failures and makes you coffee for when other stuff breaks and you're working overtime to fix it they don't want to change anything.

>There is also the usual problem of self study, in that you don't have a roadmap and can waste time easily.

Can you expand on what you mean by "roadmap"?

To me, a roadmap is very easy to get and can be arrived at from different angles.

method 1) Pick up an "Advanced Mathematics" book and start at page 1. The sequential chapters of that book would start a roadmap. If page 1 looks incomprehensible, look at the preface/introduction to see what the author lists as prerequisites. Seek out the book(s) on the prerequisites and start on page 1 of that book. If that prerequisite looks like gibberish, then look at that book's prequisite. And so on.

method 2) Google "advanced mathematics study roadmap" and look at various answers from math.stackexchange.com, reddit.com, blogs, etc.

method 3) Look at the undergrad curriculum of math courses for degree requirements (e.g. Bachelor of Mathematics, Bsc Electrical Engineering, etc) published by universities. (e.g. go to http://mit.edu).

It seems like a "roadmap" for self-study is readily accessible for anyone curious.

Congratulations to Cruise!

Cruise Kyle Vogt's third acquired company. It's still ambiguous as to whether your first startup should be "hard tech" or not. I think in the case of self-driving cars it makes sense because automobiles are a trillion dollar market and the anxiety to stay competitive with the rapidly changing landscape is intense.

Plenty of room in this market yet. What is the biggest competitive advantage and who has it? Data & Tesla. Tesla is the only company with the appropriate data to make self-driving a reality faster than anyone else (tell me when Google starts collecting data in Norway). Data collection equipment is relatively inexpensive. Maybe figure out how to get people to attach sonar or lidar or tap into their car's computer to access that data. What else is a problem, even for Tesla? How about predicting pedestrian behavior and making eye contact -- or identifying if a pedestrian is disabled and sending a signal to those pedestrians that it is OK to walk.

At the end of the day the market being targeted has huge weight to the likelihood of a successful outcome.

You are taking this from the wrong angle: the fact that gold price changed from $1700 to $1050 to $1200 says nothing about value of gold - instead it says everything about the value of dollar. Simple example:

in 1915, or so, Henry Ford released Model T, first mass produced car. The price of Model T at that time was about $300 dollars, which was equal to 20 ounces of gold. Now, 100 years later, 20 ounces of gold still can buy you a brand new car, while 300$ only buys you set of tires and some gas.

"JoDS is run very differently from a traditional academic publication. There’s no anonymized peer-review process, and there’s no fee to access its contents. “We wondered what does an academic paper look like when it’s more about the conversation, and less about tombstones,” Ito says, referring to a quote from Stewart Brand that likens formal academic publishing to burying ideas like the dead. The journal is published on PubPub, a platform developed at MIT that is inclusive in ways that academia and academic publishing frequently aren’t; PubPub is an experiment in radical transparency, where almost every part of the journal is open and editable. Readers can annotate each paper, adding comments and context to what the author wrote. The editing history is visible to everyone, so authorship is no longer an opaque attribution. Hillis’ paper has executable code that can be lifted directly from the journal."
