Finance is fairly broad. People in middle management whose job is basically to deal with paper work many times say they are "Working in Finance".

Just like people working at helpdesk say they are working in "IT".

Higher finance is filled with crazy maths, if you are interested in statistics and probability then finance is the best way to make a lot of money.

Its also not "gambling,etc" - its educated decision making.
People in higher management need to make a lot of very important decisions all the time. 90% of the time they just use their "gut feeling". This is where people with strong technical knowledge in finance comes in.

Where to allocate money is a very hard question to answer, you can throw a random dart at your options or bring in complex ML models. The sky is the limit.
The answer is rather simple:

- Popularisation of the sport thanks to social media and silly videos with fancy dubstep music.

- BASE jumpers trying to push forward the sport.

- Irresponsible companies sponsoring pro jumpers in order to film "even more difficult yet" maneuvers.

Personally I tried to get into BASE some years ago, but after watching a russian documentary with explicit and horrible scenes [0] made me seriously think.

People in social media only get to see the successful jumps but not the dark side of the sport...

Isn't that math pre-level 8? It's just simple algebra or arithmetic. Interesting how little use trigonometry and calculus have.
I just get

Wrapping arithmetic makes perfect sense in many ways:

(0) It is still a commutative ring, so it has the most important nice algebraic properties of number arithmetic: addition and multiplication are associative and commutative, multiplication distributes over addition, etc.

(1) It is the ideal building block for implementing the very big integers that high-level languages need.

Trapping on overflow is a relatively minor concession in elegance: You are admitting that you want all integers, but, for efficiency reasons, constrain yourself to those that fit into some fixed amount of space. The worst that can happen is that you can't compute the result you want. You never compute a nonsensical result.

Saturating arithmetic is an abomination and simply shouldn't exist.
So the suggestion is that in 1994 (when the https protocol was introduced) we should have put big scary warnings on every non-ssl site? I don't see how that could've gone well. It's now 22 years later and people still aren't ready for that.
I suppose the difference is that you're more likely to claim compensation whilst you've got nothing better to do than waiting to get on a plane in a terminal full of posters telling you to claim that compensation than once you've actually made it to wherever you're going.

People keep complaining, but the desktop market hardly changes.

Exactly. The desktop/laptop market has been stagnating for some time. That's partly because the average hardware in those categories reached the point of being good enough for the average user. Personally, I think it's also partly because much of the PC software industry has been stuck in a rut for the past few years. Overall, for most users, the platform simply hasn't offered anything new that they couldn't already do with their 5+ year old gear.

In areas that do benefit substantially from newer hardware, like gaming or CAD or multimedia creative tools, the traditional PC has still been doing pretty well. There have been a lot of significant advances in areas like SSDs, graphics cards and monitors. There have been lots of advances in smaller, low-energy versions of relatively powerful components that have enabled high-end laptops to do things only chunky desktop workstations could do a few years ago. But these areas are only relatively small parts of the overall PC/laptop sector.

Meanwhile, entire sectors like smartphones, tablets and web apps have taken off like a rocket, by providing hardware that supports new and very different use cases, software that takes advantage of those new opportunities and, almost as importantly I suspect, software that typically is cheap and "just works".

Microsoft had well over a decade of almost totally unchallenged market dominance to figure out user-friendly installation, maintenance, removal and security/sandboxing of applications on Windows, and it rearranged the deck chairs a bit here and there. Apple came along with iPhones, almost one-touch installation from an app store and a [dumbed down|simplified] interface that anyone could use effectively, and they became the biggest company in tech in a fraction of that time.

What concerns me most about Microsoft's current direction is that they seem so determined to chase the cheap/easy sector and alternative revenue sources, which have been so effective for the likes of Apple and Google, that they're losing the default powerful/flexible platform that they've provided for the past two decades in the process, effectively stepping a long way backwards in that sector. The trouble is, because Microsoft have been so dominant in that sector for so long, where do those who still value that power and flexibility go instead, even if they are willing to pay a premium to get it?
I know that motive will sometimes play into the sentencing, so it will be interesting to see what reason he had to gain access to the servers. I can't imagine what monetary gain there may have been, so it must have been something else.

But the only way to maaster new material is to apply it to something more advanced, rather than just practice it. Rote takes you only so far; you can solve only problems you understand already. But learning new kinds of problems expands your understanding of the limits of the concepts and techniques you already know.

This is what economists do when they think we're not paying attention:

That's not "oops". That's not giving two shits about being right because being right doesn't pay the bills. Being wrong does.

If you want to see economic destruction on a wide scale, don't listen to the anti-austerity protests. Don't listen to "populist" politicians. Listen to the 'respectable' economists who have an eye on a well paid job at a corporate think tank like CATO. They truly have nothing but objectivity and your best interests at heart.

My opinions (living here):

That salary, after tax, will be roughly $90k/year, and the bonuses will be $8k, $7k, after taxes (assuming top-rate on these bonuses).

Rent for a 2-bed (decent, central, downtown) apartment will run you at around $2500 to $3500 / mo (30-40k/yr). Living costs otherwise are reasonable relative to your income. You probably don't need to get a vehicle straight-away, and there are some car sharing services out there (to visit far places, like Whistler, etc.).

Negotiate extended employee benefits (health / dental) paid 100% by the company (excluding long-term disability) AND negotiate the payment of Medical Services Plan (gov't fee - appx. $150 / mo for family) - which I think you have to pay if you're a resident.

So on the surface, yes... I think you'd be "comfortable", but you're not going to feel rich.

Curious what other HN's think...

Maybe, but not necessarily. There is a lot of space for hacking on neural network frameworks, and even people who don't understand 100% the math involved can use them to make cool projects. When you understand a powerful idea, new connections pop up and you see potential applications in your domain.

Seems like there's a market for a tiny hypervisor.
Everyone thinks they're the good guys. Even the ISIS folks think they are the good guys, that they are fighting the good fight against the infidel for the greater glory of God. That's the whole point. That's the reason that, "It's OK because we're the good guys" is not a valid argument, because everyone applies it to themselves.

"Sending people back who came illegally [is OK]" is a thinly disguised argument of that same form because we are the ones who decide what is legal. In that respect we are like the Nazis. They thought that what they were doing was OK because it was "legal", because they were "just following orders." Well, no, it was not OK. And deporting people who grew up here "illegally" through no fault of their own but rather because their adoptive parents didn't fill out the right paperwork and xenophobia happens to be running amok is likewise not OK no matter what the law says.
Based on discussions I've had here, I do agree that step one is just for more people to care. If more people care, it will eventually get the attention of hardware people.

I mostly care about this issue because of the security issues that arise (overflow is somewhere around #4 or #5 on the list of top root causes of security issues), and for all that a lot of programmers think they care about security, there's still a lot of programmers that are quite cavalier about fixing the root causes of these issues rather than occasionally fixing symptoms when you think of it.
But Carmack didn't finish college. He's using what he has. This tweet is him defending his math ignorance in a particular case.

I consider him a better programmer than me, and he is honest about his shortcomings (like in this tweet), but I am often very surprised about what things he says he just learned - things any CS undergrad would know.

It's kind of like stories of programmers who were allowed to feed punchcards to the mainframe once a week - it's amazing what they accomplished with that limitation, but one thinks how much more productive they would have been with a more robust interaction.
Momentum is the immediate problem, not large mass. Fatality due to large mass tends to take a little while longer.
This is a significant misunderstanding of statistics. Statisticians believe in truth, they just accept that it might not be possible to know it.

> So they cannot be the same thing. That's because, philosophically, two objects must be identical in every property to be the same object, and constructability is a property.

Mathematicians have proposed several different constructions of the reals. If you were familiar with, say, constructing the rationals from the integers or constructing the reals from the rationals, you would know that this is not a problem. One of the more straightforward constructions of rationals define a rational number as an equivalence class of tuples of integers, corresponding to the numerator and the denominator. We often use one of these tuples to represent a rational number, e.g. 2/3 or 4/6. And since they are in the same equivalence class, either alone is sufficient to represent the same rational number. This is despite the fact that the tuple 2/3 and the tuple 4/6 are different mathematical objects.

As for the definition of 0.999..., it's not what you think it is. There is a specific definition for infinitely repeating digits that is different from representations without repeating digits.

That is, the positive real number that 0.x... represents for all digits x is defined as L, where L is the supremum of the set containing 0, 0.x, 0.xx, 0.xxx, 0.xxxx, ...

A supremum L in E of a set S subsetof E is defined as follows: L is the smallest number in E such that L is greater than or equal to all numbers in S. I shall not prove here that L is unique, but it is. With respect to the reals and the set containing 0, 0.x, 0.xx, 0.xxx, the supremum of that set in the reals is 1.

My knowledge of the construction of the reals comes from Chapter 1 of Water Rudin's Principles of Mathematical Analysis, ISBN 0-07-085613-3, which you may be interested to read, but beware that it's considered a difficult read for beginners.

Is this an opportunity for a startup?

Help crowdsource payments for random DNA tests of the food at local stores. Fish and olive oil, to start.

If a group of people know everyone involved and do a round robin for who collects the samples and which lab to send them to, it should be more trustworthy than any alternative.

(The samples need to be sent in without packages, so employees at the testing labs can't call the stores and charge for faking the tests.)

Edit: Hmm, the business opportunity might rather be with automating lab tests..?
I think the big problem is they keep hitting the ground.
>Any time you have an entity that's low on capital but high in potential, it's bound to attract outside investors, which is in turn bound to produce current account deficits. This isn't necessarily a bad thing.

Taking on large foreign debts has pretty much led to disaster everywhere from Greece to Thailand to Zimbabwe.

Where it's "worked out", it's usually been a way for foreign investors to extract wealth from a country's natural resources.

Any time anybody tells you that the best way to grow a business is to rack up lots of credit card debt, run.

>Having outside investors provide the capital needed to ramp up your operations, can be a huge win-win for both sides.

You have to make sure that the outside investors are put on a leash (as they are in China). If you don't, you end up bringing in lots of capital causing a spike of growth for a while, destroying local businesses (who can't compete with foreign businesses) and then when it ends the economy craters and inflation spikes once again.

>In contrast, I can't think of a single country with hyper-inflation that had a successful economy.

I can't think of a single country with a successful economy that hasn't at hasn't taken the IMF's guidelines and done the exact opposite (contrast South Korea's relative success with Thailand's).
Export industries in the states have lower environmental impact than those in China. For example, the environmental impact of IP, e.g. Software development, is pretty low. Making an airplane is also low impact on a dollar-dollar basis (they have an impact, but it is well amatorized in the price). China, in turn, does $2 of environmental damage to make $1 in profit.
I strongly disagree with your statement. Skydiving is NOT "Super Dangerous".
1. it is highly regulated.. you actually need a license to practice it.
2. Statistically is a not more dangerous most outdoor sports.

3. Anecdotally, I've been a skydiver for over 20 years, in that time I've seen very few deaths. (much less than other adventures sports)

The old saying goes. Skydiving is not inherently dangerous, but it is terribly misforgiving of your mistakes.
If I can piggyback. "Other" responses should be trimmed from less-than/greater-than questions. This is pretty binary (unless you've been on HN for EXACTLY one year, but then you should just pick which category you want to be in) and allowing "other" just leaves a group that's undefinable; might as well call it "prefer not to answer".
>> Listen to the 'respectable' economists

Isn't that kind of a subjective opinion?

Liberals love to push Keynes economic theories and hold him up as some kind of expert. Likewise, Conservatives love to push Friedman's theories on the economy since it fits with their staunch free market ideas.

Even in these circles it would be hard to find someone who's actually objective about what they're seeing.
I am not the OP but I interpret "research is stuck" as follows:

Remember Altavista (and similar search engines from the era?) it worked, but everyone was using the same approach so you got the same results when you searched for a given word... Then Google arrived and the quality of their results looked like magic.

In terms of "user experience" today does resemble then: Bing, DuckDuckGo... They return a subset of what Google finds, not something qualitatively better.
> find a decimal representation of a number

0.99999999...1

This denotes the abstract idea that we take 0.999... (infinite number of 9's) and add another digit.

This is no more or less abstract than 0.999... to begin with.

0.999... is a unicorn, and 0.999...9 is a unicorn with a pink ribbon on the tip of its horn.
I... don't understand why you'd project that viewpoint on me. It's quite a bit easier to imagine that there are things Chrome or Edge are doing that are not as well optimized on Firefox (or vice versa, of course).

I think this essay asks the wrong question, and then reaches doubtful conclusions from it.

We should not be asking whether most individuals today use higher-level math in their daily lives, because the answer we get will depend on the degree of math literacy of the people with whom those individuals must interact every day. The level of discourse is often dictated by the 'lowest common denominators' -- that is, the people with the least math literacy.

For example, freshly minted engineers who are surrounded by math-illiterate work colleagues quickly learn that they must avoid higher-level math if they want to interact successfully with others at work. Over time, the level of discourse of these engineers gradually drops toward that of the work colleagues with the least math literacy.

A type of "Gresham's Law for math literacy" is at work.[1]

The question we should be asking instead is whether society would be better off if more people had greater math training and literacy. Would our debates be more informed and higher-quality? Would our decisions be smarter? Would there be more technological innovation and wealth creation? Would society as a whole be better off if more people were trained to think creatively and critically with the rigor of higher-level mathematics?

I suspect the answer is yes.

[1] Gresham's Law -- https://en.wikipedia.org/wiki/Gresham%27s_law -- states that "bad money drives out good." In this case, unsophisticated discourse drives out high-level discourse.
As a DJ, windows 8 touch was actually a godsend because I could give up the keyboard and just use the screen in the dark. Win 8 had a number of services to turn off in order to reclaim CPU, memory, and disk (necessary for real-time live shows with no glitches), but it was manageable.

Win10 refuses to stop updates, the antivirus (defender), turning off cortana is a mess, it even forces reboots as early as every 12 hours. Completely unusable for a professional. I'll have to upgrade to win 10 pro, and even then they don't make it easy, I have to edit the group policy.

This is nuts for anyone in pro audio. Even though I have thousands invested in Windows compatible software and hardware, I'm seriously considering switching to osx. Windows touch has no equivalent, this is an awesome underrated opportunity and they are blowing it.

Yes, the high caliber of HN participants is what really sets it apart, and the great moderation by dang et al that stops it from descending below a pretty high bar has prevented the normal attrition-for-attention that drives the best users away. I think the spartan design has also helped keep out people who aren't committed to a high level of online discourse.

Most platforms are going to have a chicken and egg problem. HN didn't because this guy who had millions of dollars told the people he gives it to to use HN. Pretty effective way of seeding a community.

IMO the absolute best thing about HN is that when we're discussing a news event, often the newsmakers will materialize in the thread. Spontaneous stuff like the Alan Kay AMA just happens. That is what really makes HN invaluable, and it only happens because we're able to maintain the type of community that those people want to hang around in.
I have no data either but one point is that the "ceiling" is higher. Meaning, a non-management programmer has a rough salary ceiling. Few programmers are paid $400k and it's not a very realistic goal.

My mathematics -> finance friends (that are very good) virtually have little to no ceiling and have already doubled my salary.

Like @wrong_variable said though, it depends what jobs and if they make it through (it's pretty competitive), so you're getting survivor bias from me.

The core issue here is the lack of fiber-connected base stations. The vast majority of them globally are connected with microwave connections that will not be able to handle 1gbps speeds for multiple users at once.

This is a rather significant issue, as laying fiber from the backhaul (sometimes even backbone) network requires a lot of earthwork, the fiber needs to be laid underground and active infrastructure also needs to be deployed. I don't see this happening anytime soon.
