The triangle being an equation by itself is a bit of a bummer. The obvious followup to yours removing a line would be to remove two. Exponentiation would be:

e
/
x

Logarithm would be:

e
\
b

Root would be:

x—b

Now a simple line may be too little. And it's not clear we should be using 3 different symbols ('/', '\', '—') either. But you get the idea. It's less gargantuan, and expressing the entire equation without the '=' sign, while possible, is so baroque nobody would do this except to make a point.

But what I like best with this idea is the possibility of replacing the line by some arbitrary symbol (including no symbol at all). That way, other triangular relations could be expressed without stepping on each other's namespace.

By the way, there is an obvious direction we haven't used yet:

a
|
b

I'm not sure in which cases it could be useful, tough.

---

Now that I think of it, hiding the `=` sign may not be so bad in some cases. Relations don't have to be limited with the identity and orders (<, >, ≤, ≥). They don't have to be limited to relations with 2 variables either. Other relations would have to justify their usefulness to warrant a special symbol of their own however.

And this is what exponents replaced. I think mathematical notation is like vim, it's easy to use but hard to learn. For example, I cannot imagine having to express perturbative series in this notation or any serious physical model with the "wordy" descriptions from history.
The most successful strategy civilization has used thus far is to allow market forces to operate in that portion of the market where business can be profitable and healthy competition encourages good behavior, and to tax wealth and provide government jobs to do those things that need to be done, but either aren't profitable or the private sector would not be able to provide adequate quality of service for everyone that needs it.

Many political arguments arise from disagreements over whether a given task is best handled by market or the government, but there are few who would prefer to live in either a pure government-run society or a pure unregulated free market with no government services.
Kubernetes Cluster Federation: Deploy apps across the globe
Honest question: Is it not widely accepted that

1) Eventually, and probably pretty soon (within 100years), that there obviously won't be jobs for everyone. Automation, progress(efficiency gains) and increasing population makes it inevitable.

2) That a general "goal" of society is do away with jobs. In any traditional sense. To me we've been approaching that ever since agriculture provided ability to support specialists (those who don't spend time gathering/producing the food/resources they need). Such as scientists, artists and soldiers. The jobs keep moving "up" the ladder (away from production). Previous low-rung jobs get reduced in number by efficiency or replaced via automation. The end of this trend is that all basic needs are met by 0 to a tiny fraction of a percent of human labor and rest are all free to pursue specialist activities such as science, art, and killing each other.
Does it require a java applet?
I'm sure this is causing some people on HN real, excruciating pain. However, this application was built according to the standards of its day, and I don't know that it's so unreasonable to expect them to hire at 6 figures a developer for no "real" benefit.

And, the "IE" of today could be the "Chrome" of tomorrow. I don't like this situation (does anyone?). I wonder if for CRUD apps like this, it'd be beneficial to have a limited subset stack guaranteed for long term ABI compatibility, similar to CoreOS for binary runtime environments?*

While it is true that the fertility rate goes down with increasing wealth, this may only be true up to some point. With wealth increasing even further the fertility rate seems to start rising again. Whether it crosses the replacement rate again is up for debate. See the chart on the Wikipedia article for income and fertility [1] for an illustration.

>It would be perfectly possible to retrain the long term unemployed for all but the most difficult design and management elements. They're not done because the metrics of Wall St deem them "not profitable" - which means traders can't make quick gains out of them.

Part of the reason that training is not profitable is that there is no real way for companies to recoup money spent on it. If you spend large amounts of effort training someone, you still have to pay them the same salary as someone already trained, or your competitors will hire them away.

Sad of course, and something you will see a lot of. Some company hires out the development of its web presence to a contractor. The web moves on but the web site still works if you match up the tech with it that was current at the time it was developed. So rather than pay another contractor to update your already "working" web site the bean counters say "Just put up a message telling people what they have to do to make it work."
> (3) is ridiculous because it's an insane strawman that you set up solely to be ridiculous.

No, (3) is insane because it implies that biologically-driven preferences can change dramatically in just a few decades.

> You've defined any non-biological change in preferences as sexism.

That's (2), not (3). And I'm not sure what else to call socialization that discourages a particular gender from pursuing a high-reward field like computer science. I'd certainly call it sexism for men to be socialized to avoid well-paying jobs in nursing.

> they have self-selected into certain fields that appeal more to them than others do.

Why do they prefer to forgo a field like computer science or engineering? Is it because it's mathematically intensive and detail oriented? In that case, how do you explain half of all accountants being women? Is it because women care less about making lots of money? But plenty of women go into medicine and law. The "women prefer to forgo a popular, well-paying field" theory only makes sense if you don't bother to ask "why?"

And it's hilarious that you keep criticizing me for not offering evidence, when your whole position seems rooted in "women prefer certain fields, because [???]". Seriously, what goes in that box?
For me the trickiest thing to wrap my head around is that Mandarin is heavily tonal, and I've never had to deal with that in my life, making it a difficult thing to introduce my brain to.

Some words mean 5 different things depending on how you vary the tone throughout the word; I'm no stranger to simple variation as I had to deal with emphasis and inflection while learning Spanish, but Mandarin is a whole other kettle of fish.

I'm more than happy to accept that maybe I didn't put enough effort in or am generally poor at languages (only speak two), however I struggled to learn a handful of words per month.

It is also a location problem. If you have bought a house but can't sell easily or don't want to move then you can't go to a place in the United States that has more jobs. For example right now in Grand Forks ND there are walmart jobs $14-$18 an hour and apartments for super cheap (with electricity included) for $450 and up.
Okay, YES, Rails had docs, but that's the attitude I see: use this, do this, put your code here, we know best. The docs do not ENCOURAGE understanding of how Rails works, or why it is the way it is.
Well if AI can replace software engineers then it can probably obviate many other jobs as well, meaning there would have to be greater societal restructuring than just some out of work engineers finding new careers. If you are 30 and you're worried your job will be automated away before you retire (but before universal income), perhaps you should get a head start by learning new skills that are harder to automate.

I wonder what your alternate theory that fixes the unemployed 50 something factory worker is? Legislation that ensures job security? Pension? Severance?

If you assume a reasonably recent browser and server, then it does. Certainly one might not grant that assumption, but I don't think it's outright wrong to make it, either. Depends on your approach.
I've not seen that warning before. I just tested on a file I downloaded, which had the 'Zone.Identifier' stream. Using Explorer, I copied it to a FAT32 volume, then back to my NTFS drive. Sure enough, it lost the 'Zone.Identifier' stream, and there was no warning when I opened it.

This is on a fairly normal Windows 10 installation. YMMV on different versions, of course.
wow, thanks! that is an incredibly interesting article, and way to learn trig, I think I would have gained more insights had that been part of my introduction.

I'm sort of wondering if that terminolgy sounded more natural then because in "older" English, closer to Germanic roots, it was natural to create new words by pasting together morphemes.

If things are spread out and randomly distributed then you have a living economy reachable by foot. There will be a bakery, a barber, a library, and a cafe in your neighborhood. If you put all the houses in one place and all the bakeries in another, then you have to get in your car or on the bus to travel between them.

I always trot out Paris, but that's only because it's such a good example.

We did a scenario planning project where you put together human trends and factors to try and predict several versions of the future 10 years from now.

In one of our scenarios was a future where humans bounced from job to job (high turnover, low unemployment) and skills-based education was cheap and easily accessible. Some of the factors leading to this was the "established"-education bubble bursting, increased automation, and less desire for consumers to own assets while still having access to them (variable sharing economy).

A #2 type of future might not be that unrealistic.

« the whole HTTP/2 name is massive misnomer (since it doesn't actually support HTTP) »

HTTP/2 is backwards compatible. It may not be your idea of the right direction for HTTP/1.x, but that doesn't make it a misnomer. To be honest, the only people that can decide if it was the right name for it are the IETF and they already made that decision. There's a reason that the name SPDY looked nothing like HTTP, because Google left that decision to the IETF as the standards body controlling the fate of the HTTP protocol.
The part you are missing is:

TCO goes way down -> price of product goes way down -> sales go up because price is lower.

It doesn't always happen that way, but sometimes it does. uber is a good example. By reducing cost of car rides, I pay someone to ride in their car 10X the amount I used to.

If Americans wanted to live a 1916 lifestyle, not many of us would have at work. But we buy a lot more stuff and use a lot more services.

I used to trade FX. With this bank as well, though I didn't know these two guys.

So there's two ways to buy something: agency or principal. If it's agency, you say to a guy "hey, go and buy me some widgets and I'll pay the amount and you'll get a little fee".

If it's principal, you say "hey, make me a price that you want to trade at, and we'll trade, and how you make that profitable for you is your own problem."

What is front running? Generally, it's where you're the agent, but you use that fact to scoop yourself some widgets before you do the trade for the customer. Now naturally, even if you are not literally executing an order for a client, that flow information is useful to you. For instance you might guess all the clients are spooked because of some news, and after two of them call to do the same trade, you guess they'll all do so.

3/4 pm fixing question. Actually seems a reasonable suggestion to do it at the less liquid fix. A lot of derivatives are fixed at 4pm, and there may well be some guy out there with a strong interest in moving it. I recall the price action at 4pm being very odd on many, many occasions.

Anyway, what's confusing to me is why didn't Cairn just get a firm price from HSBC? You can phone a guy and ask for a few billion if you like, people do it all the time. Alternatively, anyone can get an unknown execution price; the banks provide a GUI to everyone who wants one, and you can click the thing until you've got your amount done. The market won't run out of GBP.

What they seem to have done is give a licence to HSBC to trade their order in a way that was bound to create an unequal conflict of interest. The bank can always make it profitable for itself, because they're in control. The customer is bound to be disappointed when they have both an unknown price and price impact against them.

It's possible that since Cairn would be a "real money" customer things are not quite like when I was a customer. Hedge funds are called "leveraged" customers, and the sales people tend to be different, with a different focus. The FCA might also be taking a view that real money guys need better protection than speculators.

I definitely wouldn't have called in to do a single massive trade. I'd have gotten on the GUIs an clicked my way through, with an uncertain outcome, split across various banks and over a few days. It's not as if the profits from selling a business unit will be lost by the currency move between the sale and the cash disbursement to the shareholders.

Agree that you can't lie to the client about what you've gotten up to. That part is undeniably bad.
I would speculate that it lands on skids. Skids are pretty lightweight and will do fine for landing, but you need a lot of power to take off with them unless you're on ice or snow.

(You know your landing gear is up when it takes full power to taxi.)
The same thing crossed my mind. In his statement to the judge, he says:

I very sincerely, on behalf of my country and Obama, my state and Arnold Schwarzenegger, myself and my family beseeched her to be lenient in her judgment.

Schwarzenegger was governor until 2011, which would presumably date his escapades to sometime between 2009 and 2011. Hopefully it's long enough ago to clear Irlan or anyone else mentioned or photographed in the post of any problems should it get traced back to them.

Great story, by the way. Well told.
Yes, there seem to be a common misconception that it's density as such that matters. Successful big cities are not based on density, but the fact that they go on and on (making some areas very dense indeed), while San Francisco quite quickly becomes suburbs. Everyone always comes dragig with examples of cities that developed over decades. A more apt, but still unlikely, comparison would be something like Vancouver. Personally I think that the ship sailed when the tech companies built campuses instead of towers.

Why think of ternary relations? Well, if you do not recognize that there is an "Any two variables here determine the third" structure here, you are missing a fruitful insight into the matter. That's why. Sometimes that's a useful perspective, sometimes perhaps less so.

That can be useful not only for exponentiation/logarithm/roots, incidentally. It can be useful to recognize with addition/subtraction/subtraction, or multiplication/division/division, as well. These all have a similar structure: three values in a relationship, such that any two determine the third. The triangle is supposed to help recognize this structure, though it helps with nothing else on top of that.

"By converting exponentiation and logarithms into infix notation, you do away with one side of the triangle and you can learn the relationships by just thinking 'it's exactly like multiplication and division, except [etc]'"

The problem is, there's rather a LOT of "except". Standard * is commutative, while ^ isn't. * is associative, while ^ isn't. * turns additions on either side into additions of the result, while ^ turns multiplications on left into multiplications of the result, but multiplications on the right only into chained operations (i.e., a ^ (b * c) = (a ^ b) ^ c), while additions on the right are turned into multiplications of the result (i.e., a ^ (b + c) = (a ^ b) * (a ^ c)), and additions on the left are turned into binomial theorem expansions!

These are big differences! There are particular similarities too, of course. There's a mix of similarities and lots of differences. What that amounts to pedagogically is... a muddle.

Anyway, the triangle manipulations in the video aren't at all compelling to me, but regardless, the ternary relation structure IS useful to recognize (that any two out of three determine the third, and this is all the various traditional functions do), and again, this is something to be recognized not just for powers, logarithm, etc., but even for our familiar addition/subtraction or multiplication/division problems.

>And yet, this turns out to be the most succesful strategy civilization has used so far.

The period in which the American economy was growing most was when it was also most organized. The post-war consensus was about scientific management of industry and the economy, not about free markets and profit maximization; that dogma only took hold in the 80s (both in business schools and in politics), and it has been a steady downhill since then from the relatively sunnier period of high-level management. The American economy was heavily planned through most of that period (mostly through the military), and the beleaguered stump remains in the form of public funds for research and development flowing into private industry (the Internet, biomedical research, semiconductors, defense, etc).

What short-term profit mostly succeeded at doing was producing the largest and most rapid accumulation of private wealth and power the world has seen in a century.

Non-sequitur, I also found this, one of the coolest figures I've seen in a while: http://www.zerohedge.com/sites/default/files/images/user5/im...
There hasn't been infinite work for quite a while now; I've heard the theory that Japan invaded Manchuria in 1931 so that they'd have something to absorb their industrial productivity -- because they were running low on domestic stuff for factory hands to manufacture.

Of course, it didn't help that wealth was very heavily centralized in Japan -- the eight zaibatsu families, the Cho:shu and Satsuma fiefdoms (the army and navy respectively), and the imperial family owned probably a majority of the country's wealth, and the common people were too poor to buy very much or stimulate the economy...
If 2 is true our politics (at least in the U.S.) haven't caught up. We have to be comfortable with the idea of simply giving money away to people who are not earning it, or giving them more than the market would otherwise bear.

One of the ways we could do that is by making university tuition free, to say "well, if you can't get a job, you can always spend your time thinking instead." Instead we're restricting access to univerisities more and more based on the idea that a university education is only about getting a job and you should have to have "skin in the game".

We've been making it harder, not easier, for people who aren't working to access the collective product of society, and we're all poorer for that.
Incidentally, sure, we could just pick ^ to be our basic operator and define everything else in terms of that. Well, just as well, we could define everything in terms of logarithm. Or everything in terms of roots! In fact, one might ask why you are so happy to define a logarithm operator v to undo ^ in one direction, but do not want ever to define and work with a root operator to undo ^ in the other direction.

Is it because we can get away with saying a^(1/n) instead of n-th root of a? Well, just as well, why should we have a division operator? Instead of a/b, we can say a * b^(-1).

Or perhaps we oughtn't have multiplication, or exponentiation with arbitrary bases. Perhaps we should just have addition, negation, natural logarithm, and the natural exponential. Then we define a * b as exp(ln(a) + ln(b)), define b^c as exp(c * ln(b)), etc.

But, of course, just because F can be expressed in terms of G doesn't mean it's always convenient or pertinent to think of F that way; sometimes it's pertinent to think of F just qua F, as an atomic entity in its own right. And, thus... the proliferation of different functions people talk about.

Though this does mean people then have to keep track of what all these different functions are defined as, and trace back through how that makes them relate. So... I don't know. I don't have all the answers. Yet.
Right, users see HTTP and HTTPS, they don't see /1.0 versus /1.1 versus /2.

(There's a good argument that users seeing HTTP versus HTTPS was a mistake, too, versus just secure/unsecure markers in browsers. TLS shouldn't have needed a new port number and URL prefix... but it is way too late to fix that now.)
How does she barely make minimum wage as a speech therapist? My mother worked in the school system for 20 years making nothing. Now works in skilled nursing, people that just had strokes and other trauma learning to speak, eat, or breathe correctly again. She makes around 80k and regularly picks up side jobs at other facilities for $50+ an hour.

I have another friend from college who works in a hospital and makes 70-80k. Although there isn't much increase over the years in a hospital.

Just curious because I'm familiar with the field. Are things different in Europe?
