This is just something I thought of and I am not sure if this makes sense but mathematicians explore objects much in the same way particle physicists do. So the physicists bounces particles off each other and see what happens to understand how these particles work.

Similarly, mathematicians study objects by looking how they act on other objects. So if it turns out that two differently defined objects have the same actions on other objects, we call them isomorphic and don't really distinguish between them.

So for instance, we say that the set of rigid motions that preserve the triangle and it's orientation is the same as the set of permutations of the roots of say: x^3-3x+1 even if the two sets are absolutely not defined in the same way.

Hope that makes some sense.

That really depends on the job. If the job is primarily technical then people skills are a fringe benefit. Nobody cares if all your engineers are great at giving presentations as long as the engineering gets done and a great presentation gets given and if the guys writing code are bad at it but great at making it look good then they're on borrowed time.

If the job involves lots of working with people then social skills become more important. Even if your guys write great code, you need to be able to convince the people who write the check for it that it is great code.
I'm not trying to hate on Notch, just observing that even a small % of equity would have been enough to cover his employees.

And it's moving, eastward. Old Faithful is getting a bit less faithful, and shorter, as the years pass, while new hotpots and geysers appear east of it's location.

On the plus side, it appears that we will have a fair bit of warning before Yellowstone goes off, for all the good it will do humanity.
> It enables organization-wide refactoring.

How do you mean? If I refactor the backend, for example, an iOS dev still needs to come in and refactor the iOS app, so the refactoring still happens independently.

> It facilitates code sharing.

That's handy if many or your projects are in the same language, true. That generally didn't hold for the projects I've worked on.

> It provides easy access to examples of how code should be used.

True, but that's mostly the same as having a GitLab instance (or similar) installed.

> You don't deploy source, you deploy packages.

Sounds like I just have different needs, in my area of development (Python server backends) the source is the package.
The key is enabling maximum developer leverage - and one aspect of this is to get rid of as many systems errors and inefficiencies as possible.

I think build systems and internal code management schemes are large interconnected systems. It feels fairly pointless just to expose one facet of the entire systems since the total system encompasses all of the individual entities dealing with the codebase - including developers, platform - the whole works.

For example, I see no overhead in my daily work from the fact that our codebase is split to several libraries with dependencies through explicit built release versions. On the contrary,there monorepository would be just horrible.

So, before saying X is great one should firsr define what type of software is built, what is the specific toolchain, what are the specific configurations, how many developers modify the same codebase frequently, and so on.

Agreed, I should think that anyone interested in his personal life already follows him on Twitter and would have already seen this. Hopefully it will lead to a bigger interview / blog post from the man himself on the subject as it's certainly interesting (to me at least, and I imagine a lot of the HN crowd).

I'd be interested to see some data on this, but every single cab driver I've talked to in San Francisco was on the per-shift model. And when I lived in Chicago, same deal there. That'd be dozens in each place.

I also agree that cab companies are kinda terrible, but that doesn't make Uber any less terrible. If anything, I think it's a sign to us that we should be especially careful with Uber: if a few local companies competing can end up all being pretty bad, one nationwide monopoly run by ugly people can only be worse.

First, these are all exaggerated cases, inspired by experience. I appreciate the infrastructure a great deal, but I'm saying that there's a tremendous amount you can do if you focus on learning concepts and have a computer. School doesn't even care if you understand concepts; memorization is usually sufficient. And anyone who understands basic conceptual 1-var calculus and programming can indeed easily write functions in plain C that perform numerical integration and derivation because the hard part about calculus is putting up with the countless algebra tricks that are not obvious to mortals. Don't know how to manipulate that monstrous algebraic expression to take the limit? Good thing your computer can use some tiny floats. People who are not going to be math/physics professors or NASA physicists who need to plan a Mars voyage to the nearest nanometer would really benefit from focusing on the concepts instead of algebra. And my calculus teachers were pretty superb, by the way.
It's basically duck-typing. If you can do arithmetic on it, it's a number. If you can do matrix operations, it's a matrix. If it satisfies the axioms of X, it's an X.
Everyone I've ever met who's worked at Twitter hates the monorepo.

They have a single git repo with way more files than that tool was ever designed to maintain. As such, normally instantaneous commands like status, log, ls, etc. take an inordinately long amount of time to execute. Apparently their onboarding process is "have someone copy his working copy to a flash drive, then copy it from there to your laptop" because git pull would take too long.
Agreed, I bought the book and am doing the class as a "refresher". I put refresher in quotes because there is stuff in Strang's class that I know we didn't cover in my university class, notably SVD. Strang definitely has a way of really helping you deeply understand the concepts. I remember the subject pretty well but I don't think I understood it as well as I do now.
I'm having a hard time feeling sorry for the guy. He thought his success was a testament to his engineering greatness, acting like he was John Carmack. Money doesn't buy character, decency or real friends. Notch is feeling the sting of his arrogance? He doesn't have my sympathy.
Would be interesting to find out how old you are? I'm 31, all my friends are married and popping out babies and while I'm in a very happy long term relationship, I honestly don't see the appeal (thankfully my partner agrees).

Try deploying and a different OS with easily understandable UI. Make it easy so that companies can issue laptops and upon first login the machines are appropriately imaged per the user needs. Make sure that strong user limits are in place to prevent users from running bitcoin-mining/porn-servers/or-worse on corporate machines and then and only then, you may have a shot at disrupting the Windows enterprise stronghold.

If you were to poll corporate user income and their provided OS, you will likely find that 99% of workers earning low wages (i.e. not trusted by their companies) are provided windows, the more someone earns the more likely they are to have a choice in OS from their employer--just my hypothesis.
But there's a difference between looking at the list of root certificates that Microsoft say Windows trusts and looking at the list of root certificates that Windows trusts.
Yes the do play catch up. We don't want those pesky free (in what you can do with them) mobile devices on well understood platfoms to treaten the sweet vendor lock in gig we have at the moment with arm. Or the carrier subsidy model.
It is obvious that contigenics is in China, they admitted that in their post; you were only calling out nationality, but that isn't even relevant. If they don't have a VPN, like I don't, where else are they getting news from? NYT is blocked, WSJ is blocked, BBC is blocked. You don't have to tell me to "stop reading NYT" because I can't! So your whole argument makes an assumption that is not even technically correct. So what argument are you making here? That all news sites are freely available for browsing in the PRC? Because if that's the case, well, we obviously live in different worlds.

I think he means that mathematical objects are pure structure without substance. They are defined only in relation to other objects and there is no deeper meaning.
The cab drivers in SF always complained to me about their relationship to the dispatcher, but I'm not sure I ever grokked that.

Chicago cabs, I get an earful on leases and minimum number of hours they have to work to pay for their cab/medallion.

You can be on a shift AND in hock to the cab company; the two aren't mutually exclusive.

To me it seems like at least with Uber you can set your hours, and there's transparency regarding your capital costs: you buy/lease the car yourself, so no medallion or other lease shenanigans.

I'm not in love with Uber, by the way: I think Uber should have to comply with a lot of taxi regulation that they don't currently comply with.
I see. Let me view that NYT report right now. Oh, wait, I can't, for some reason NYT is blocked here. Well, I can check out china daily at least.

> How do you mean? ... so the refactoring still happens independently.

Not all refactors modify APIs, and even some that do can be programmatically applied. Suppose you've deprecated method Foo(..) and have a replacement Bar(..). With access to all the source, you can change things globally, it's great. One funny programming 'mistake' that creeps into code that's been around a while is dodgy looking ternary operators:

return (foo ? true : false)
return (foo ? false : true)

With a few minute's work, one engineer can metamorphose all of these into:

return foo;
return !foo;

> That's handy if many or your projects are in the same language, true.

My day to day work is almost exclusively C++. Thousands of other engineers are in the same boat as me. We all benefit from a fabulous tools team.
Can you give examples of some good ones?
Bitcoin is 'anonymous enough' given the current regulatory environment. As the regulation catches up, Bitcoin will evolve to be precisely as fungible as is required to support its users. You see that happening now with Gregory Maxwell's research. The protocal can and does evolve. Fungibility has opportunity costs, and Bitcoin simply hasn't needed to add these features in yet.
The easiest way to kill bitcoin is to make those black market activities legal. Until then, there's an underserviced market that Bitcoin enables.
Traditional DBMS's get performance by optimizing storage down to the physical layout of the data on the hardware.

Hmm. You're right.

The general problem remains. It's difficult to build momentum in a platform that operates as an all-or-nothing proposition. 9p might offer a way in though.
I get that it's isolating, hard to trust people, and difficult to find tasks rewarding when you can have everything you've ever wanted ...but it can't be all that bad because this problem can be self-remedied.

Theoretically Notch could bring himself out of the stratosphere by removing enough money from his account that he can be perceptibly normal. e.g. donate most of his fortune and leaving himself only enough to qualify as 'FU money'
For safety reasons...when you have a camera man (or two), an audio guy, the producer and other assorted folks who are not safety certified for everything in your lab, you cannot do your normal work. Most protocols are multi-dayand you wind up having to do them multiple times, they tell you to block out 2 weeks.
My point is not that BMW will win. My point is that automated cars make it a low barrier to entry. Many, many companies could reasonably think to seize a piece of the transportation-as-a-service market.

The list starts with every car company in the world, because a) their execs all went to the same management schools and learned the same lessons, and b) they all have the necessary factors for market entry, which I'd say include 1) access to capital, 2) access to cars, 3) ability to make software, and 4) a strong consumer brand.

But the list definitely will not end with Uber plus the car companies. Transportation is 8.5% of our total economy, and automated vehicles will totally change it. Hopefully they will also reduce it to 4-5% of our economy, so there will be a lot of bloodshed, but in the chaos there will be some great opportunities.
I'm not too worried, like all prohibited substances and devices (except maybe weapons of mass destruction) there will always be ways to get what you want if you want.

I don't know what a gerund is, and I've never needed to except in 8th grade grammar tests, which I failed. Yet I got a 79/80 on the writing section of the SAT because my grammar is pretty solid. I've been in a remedial English class, actually, with ESL kids. Like yourself and most other rational people, I am a big proponent of acquiring knowledge on diverse topics. I just think people should be able to pursue the topics they're interested in instead of dealing with distracting busywork that old people decided was a good fundamental curriculum. Do you fail to see the problem with schools forcing kids to memorize things about Native Americans and Greek columns and long division (etc.) when 1) most do not care about such things and 2) even more will never need to know such things? It's one problem to have an outdated curriculum and another to force a set curriculum, even a great one that works really well for the average student, on kids.

When Open Exchange Rates [0] began making decent returns - not a $2.5billion exit trajectory by any means, but certainly enough to set me apart from my peers - I felt I was on the path to something great. I thought something like "Now that I don't need to trade my time for money, I'll be [popular, happy, fulfilled, 'enough']... and I'll grow automatically."

I awoke years later (thankfully only two) to find that I had none of what it would take to be happy, or to grow as a man, and a seeming eternity of free time stretching out before me to enjoy my comfortable isolation.

I only had to taste the false freedom of wealth - really just an appetiser - to know that no amount of resources would fulfil me if I could not meet basic emotional needs, go through pain and challenge, be vulnerable, build relationships, and self-nurture. God forbid I ever come into the kind of money he has - but if I do, I pray I would have the courage to start from scratch to build the life that nourishes my spirit.

I think many will take a high position, point a finger at this man, and feel good about themselves. It's easy to look at him and say "High value problems," and "He has nothing to complain about," or even "He should be X/do Y...", etc. The real tragedy for me is that his issue can be so socially unacceptable.

I rate him for being open and vulnerable about this part of the journey and hope he finds the peace he deserves.

Well, reading the PDF was anticlimactic. Why? Because page 2 of the PDF describes the 12 games that were used. They were games that test memorization, puzzle completion, and pattern matching.

In other words, the "commercial video games" used in their research were "brain games" and not Pac-Man, Mario Bros, and Call of Duty, etc.

If you've ever taken a real IQ test where the proxy shows you cards to match or pictures with "missing" data, the 12 video games they used are very similar in spirit. It's not surprising that there is high correlation between the scores of those particular types of video games and real IQ tests.

However, that's not to say there is zero correlation between blockbuster video games like Call of Duty and IQ. Maybe another study will pursue that.
The false promises of dedicated IPs
Its actually pretty simple to implement on your own. I am not big of device. I feel it does too much magic. It should have been just a api layer and not touching views.
> Here we show, for the very first time, that commercial video games can be used to reliably measure individual differences in general intelligence (g). One hundred and eighty eight university undergraduates took part in the study.

Is this a joke? reliably measure ? 188 students?
So are you trying to tell me that if I could play Call of Duty with A. Einstein I would be humiliated despite him never having played a video game in his entire life?

I know people in the life sciences who admit to frustration over the pressure to publish and the abuse of statistics.

But I don't know if statistics is the entire problem. It seems to me that a feature of good work in the "hard" sciences is that a problem will be approached from a bunch of different angles, so that the result doesn't really depend solely on statistics.

Synthetic chemists have to perform multiple orthogonal tests in order to announce a new compound, such as IR, NMR, X-Ray crystallography, and elemental analysis, on top of describing a mechanism for the compound's formation and performing reactions with the compound if possible.

Traditionally, to prove discovery of a new element, it wasn't good enough to see a blip on a mass spec. You had to do chemistry with it.

In my view a problem with data driven science is that you can do statistics without even knowing what you're actually studying. But if you don't know what you're studying, then you can't attack a problem from multiple angles because you don't even know if your tests are all measuring the same thing. You also have no tools to ask the hard questions about whether the results really make sense.

Ultimately, GUPC was selected as the winner with the highest technical score and lowest total (fixed) price proposal at $3.221 billion.

Actually, most algebraic tricks in calculus, which are what make it challenging, are pretty unnecessary to know if you can program a computer or use existing math software. Conceptual tricks, on the other hand, which might be more aptly called "conceptual applications," should be understood and derived. The unfortunate thing is that many students get so accustomed to memorizing tricks that would indeed require really advanced math abilities and lots of time to derive that they gloss over valuable concepts that they should actually understand very well.
I don't know what specific university you're going to, but many university libraries have free access to journals for students.
