Ordinary people want an EV that looks no more spacey than a combustion engine car, but comes with wireless upgrades, long range batteries, large trunk, fast acceleration, high safety rating etc.

That describes the Chevy Bolt.[1] It comes off the same production line as the Chevy Sonic and looks about the same. At one assembly station, either a gas engine or a battery pack and motor go in. Reports are that every fourth or fifth car off that line is a Bolt. GM has the option of adjusting that ratio based on sales. That one line can make 90,000 cars a year per shift. They're only running one shift right now. So Chevy has, running right now, the capacity to make as many Bolts as they can sell, and can adjust output as needed.

I'm always bemused when I see HN posters evaluating Tesla's finances like they were a mature company, instead of a fast-growing one. By the measure you're using for Tesla, almost all startups should be shut down.

"Fixed costs are too high, no sign that they will ever make a profit" is something you can say about almost all startups.

Assuming you are in fact the other newly created account with the random-looking username above, then you explicitly stated that Signal "forces you to send messages over Google servers".

This is straightforwardly false: the user does not send anything over Google servers in the course of using Signal. Signal sends an empty push notification over GCM to users who have received a message; while technically true, to, in a discussion of a messaging platform, refer to empty push notifications as sending "messages over Google servers" is prone to misinterpretation as false statements that the "messages" going over Google servers contain any information about the messages being sent over the messaging platform.

Additionally, the use of GCM only allows Google to extract metadata about when a user receives messages; GCM messages aren't necessary to notify you when you've sent a message, so I'm not sure how you propose that Google can infer when a user sends a message and who that user is messaging. Could you elaborate on this?
So I too love the idea that we don't need dark matter to explain all the gravitational effects we observe in the universe. However, is it just me or does the falsification of this seem a bit sketchy: if we find a dark matter particle...then my theory is false. That's a bit like saying...oh yeah if we find a different way to unify general relativity and quantum mechanics...then String Theory is false. It seems like there should be a 'smaller' way to falsify it.
Wealth is the only credential required for investing. If some or all of today's investors crash and burn, loads of other wealthy people will find better opportunities with reduced competition from today's foolish investors. (Maybe they aren't investing now because their risk profiles require better opportunities to get the cash out of the mattress.) If one hasn't somehow hitched her wagon to the fools, their poor investments can't hurt one at all.

This "somewhere, someone is losing money!" concern trolling fallacy is one "usefully idiotic" source of our repeated bailout follies, so I'd like never to see it again.
Everyone want to be like China and control their internet, their people and their industry and avoid external competition. Most countries can't quite do it or are unwilling to because it does have downsides.
Pretty much all of this post is about unpacking the "See a problem" step of your recipe - if you don't get past that, none of the rest matters.

I'd argue that where RethinkDB fell down is on a step you don't list, "Understand the context of the problem", which you'd ideally do before figuring out how many people it's a problem for. Their initial idea was a MySQL storage engine for SSDs - the environmental change was that SSD prices were falling rapidly, SSDs have wildly different performance characteristics from disk, and so they figured there was an opportunity to catch the next wave. Only problem is that the biggest corporate buyers of SSDs are gigantic tech companies (eg. Google, Amazon) with large amounts of proprietary software, and so a generic MySQL storage engine isn't going to be useful to them anyway.

Unfortunately they'd already taken funding, built a team, and written a lot of code by the time they found that out, and there's only so far you can pivot when you have an ecosystem like that.
This treaty only binds the governments that signed it, i.e. only the governments of Earth. If people colonize Mars, couldn't they create a new (local) government that would then be able to claim sovereignty of the planet?

DSGE models aim to be explanatory models of an economy. They are not the best at predicting (bayesian VARs do better forecasting, there is a tutorial on it in my quant econ link) but they turn out to do forecasting decently well, too.

The reason that is is that purely statistical/predictive models of macro are subject to the Lucas Critique [1]. It says roughly, if you observe an economic relationship is happening, but you don't have an explanatory reason why it is, it's a bad idea to use it for policy prescription.

The NY fed model has a whitepaper here [2], which should be accessible to the technical data scientist (technical, but not prohibitively so).

Their readme points to a few posts on using it, I think the open source code comes with a csv for example input data. There should be publicly accessible macroeconomic data in a few places for you to play with it, say at FRED or the World Bank. I think Julia has a Stata-style api package for FRED data, making the data processing easier.

Have fun!

Just comparing K to something like Python.. Though, personally, it only became (somewhat) readable after playing with APL and J for a year.
I agree that it sounds elegant, especially since it puts entropy/information into the core ontology so as to explain the arrow of time and thermodynamic behavior as part of the same theory that can account for Einsteinian space-time.

I just wish I understood enough physics to tell this paper from elegant-sounding word salad!

I've always been bemused by EE wallet cards that contain:

V = IR

R = V/I

If an EE does not know this formulas, he isn't an EE. If he understands so little about algebra that he needs the three forms, he's going to be misusing the formula.
I wouldn't mention it if I didn't hear it in others voices. Be it sexuality, love, education, society, work, celebrity... so many ideas get into our heads, so many of us get sidetracked.

And I don't want problems to go away, just to get them outside of our heads, instead of self alienation by lack of understanding of what is happening and if or not you're alone in this case (my belief: you're often not).

I also believe that older social groups had a more balanced structure where people would share more and listen more rather than western cultures where it's dealt with by outsourcing growing into institutions.
This would probably go both ways. In fact, as Earth has so many satellites (GPS, communication, etc), you could simply "nuke" the orbit.

I wasn't particurarly supporting the argument that it is a foolproof way to measure buying power. Just that the decisions central banks make about their currency denominations aren't arbitrary and they do lend insight into the economies that they manage. The €500 probably isn't about buying power but it does tell something about the motivations for easing a transition to the Euro. In fact, now that the transition has been completed, the bill is being phased out. I wouldn't be surprised if that was the plan from the beginning.

What would you guys recommend for someone like me who has a strong background and education in ML algorithms (a PhD in a similar field) and math however but has very little formal programming skills. When it comes to coding I usually find myself hacking together code with the intention to come back to it later but never do. I have never had a problem finding and keeping jobs but have always felt a little insecure when it comes to writing code with CS majors, even ones with just a few years out of college. Any good material to help get me up to speed on the CS part in particular with common ML problems?

I know a software engineer who worked for one of the big quant firms in the north east (forgot the name...it's big) before people even knew what quants were.

He worked for them till he got out on his own. All his backtracking software is written by him and is in C (nice GUI, graphing feature, etc). He uses it to find his edge.

His trading platform is Excel...Obviously he doesn't do HFT...his trades are measured in days.

I know - 1 data point, but if a software engineer who is better than me in both trading & coding is using Excel, I'm not going to knock it.
Everybody's right. Excel is a powerful, flexible tool that also has almost no guard rails and all but begs people to make profound mistakes and huge messes. There's too many people who sneer at spreadsheets when they should be using them, and there's too many people who use them when they shouldn't.

No contradictions.

It would be interesting to see if anyone could get some power Excel users together and construct a next-generation spreadsheet that encouraged better practices and worked to prevent huge messes. Spreadsheets are like SQL, where the initial release was so far ahead of its time that it managed to entrench itself into the very fabric of computing, even though it's long overdue for a reimagining.
They have APIs that other developers can use to build things, but not for embedding content into the pages itself (I haven't searched so much about Reddit but I have about HN). So basically these libraries are for pulling data, not for pulling functionality. In fact I am using one of them, Algolia on the back-end to pull the data. For truly embed it we'd need for HN to provide this functionality with some Javascript library/iframe/other, which they currently don't do.

"For me, anything in the future revealed by wikileaks will be under an aura of suspicion and disbelief."

You can question Wikileaks motives or political beliefs, the relevance of the emails, the timing of the publications, or the twisted reporting third parties have done of the underlying documents, but Wikileaks itself has proven itself to publish accurate records thus far.
It's fine if this wouldn't work for you. Nothing works for everyone, and that's sort of the point. Kids are funneled through an extremely rigid sequence of topics focusing entirely on rote application of manipulative techniques. Anyone who doesn't conform to this sequence is just left to painfully deal with it on their own.

I remember a bit later in school I discovered algebra on my own and became really interested in it. I asked if I could take a class on algebra ahead of schedule and was virulently refused by the school counselor, who scoffed at the very notion and declared it to be impossible. Her response was so indignant that it offended me very deeply and caused me more or less to rebel against school in general. I ended up turning away from math completely for many years and didn't come back to it with any real interest or passion until I was about to graduate high school.

> If I explain 1/2 and 2/4 using pie or pizza slices and ask you how "much" pizza did you get, I think the equivalence idea clears up quite nicely.

Sort of. But childhood me would have just told you that, no, in one case I got one big piece and in the other case I got two smaller pieces. Combined they might have the same mass or the same number of calories or the same area, but the numbers you just gave me don't have units and can't be measures of area since they're independent of the radius of the pizza.
Ah, I see. I'm no expert, but I'd argue the response is "Maybe".

I think this is what blaze and pypy try to do with python: they compile it so that certain things are optimized. The harder part is that you have to generally hint for the compiler to truly be the best...

WRT to just why not use C, python/R/Julia are MUCH easier to prototype in than C (in my opinion, having used those languages). The "grail" is to be able to prototype quickly, and then identify the hotspots to speed up (which, in Julia's case, would be just inlining with C code).

If 1% of the desktop users are developers, that's the same as 50% of the Linux users, and a really big share of the Linux users are developers (really, I expected it to be more than 50% what, clearly isn't true). That's also circa 12% of the Mac users, and I bet a biggest share of them are developers than the Windows ones.

That is the reason for the ABAG housing mandates. It's why Palo Alto capped commercial office space. It's why residents of Cupertino think that 2 million square feet of office space at Vallco is short-sighted.

If you look at ABAGs desired jobs/housing ratios, on which they base their mandates, it's clear that it's insane to build so much office space since there is no land on which to build sufficient housing to offset the office space. But of course that's not the problem of the developer of the office space, it's the problem of the city, and the problem doesn't happen for years, or even a decade or two, after the office space is occupied.

It's all short-term planning done by city councils that are owned by developers.

An excellent summary of the factors contributing to the uncertainty in the forecast this year. I've not seen a write up based on other models that gets into the details like this blog does. Will certainly be interesting to see how it all plays out.
Volume isn't a particularly relevant metric here. Think of it as the resolution HFT firms trade at rather than a measure of the size of their trading activity. It's not a perfect analogy, but the point is that trade volume is not the best metric for understanding the scope and impact of HFT. It's definitely not an indicator that HFT makes up 30-70% of the finance industry in any meaningful capacity.

Here's a thought experiment: how much would things change if HFT firms traded half as much, with double the margin on each trade? Some securities would be a bit less liquid but otherwise almost nothing would change. It certainly wouldn't be a 2x difference from the status quo!
