I'm not an expert, frankly I don't even have a passing knowledge of how to value currency. My "string of criticisms" is actually one probative question: How does transaction volume imply a given value of a unit of currency?

Obviously an increase in transaction volume increases the value of currency. What is not obvious, at least to me, is that it is in direct proportion.
Agreed. Especially if I get on a good bean that I like, I want to run it's course for a while.

We are thinking of implementing some type of rating/feedback system so we can get to know preferences and curtail each shipment based on that.

A 2013 spreadsheet formula language would look pretty similar to what we see now. The format is simple and relatively easy for people to understand.

If I were able to change it, I may consider adding a left hand side to the formulas (A3=A1+A2 rather than just =A1+A2), which seems verbose but completely obviates the need for the special array formula type (e.g. `{=A1:A2 * B1:B2}`, which would be naturally expressed as C1:C2=A1:A2 * B1:B2). There are other constructions like range unions and intersections that I probably would change, but no obvious replacement comes to mind.

If you want to explore JS in excel formulae further, there are people trying to implement the formula space in JS: https://github.com/sutoiku/formula.js

BTW: if your goal is to attack the spreadsheet space by innovating on formulas, you are probably barking up the wrong tree.

Why I am no longer submitting direct URLs to HN (and neither should you)
A while back there was a kerfuffle on HN about link headlines being changed by the mods to the original headline on the article being linked to, on the grounds that link submissions are "community property" and so the headlines should not be editorialized. The problem with this is that more often than not, the original headline sucks. Such is the case for this article, which is really the content of this submission:

http://www.salon.com/2013/12/02/thanks_for_killing_the_planet_boomers/

The original headline is, "Thanks for killing the planet, boomers." But this is a flip headline that belies the serious and important subject matter, and also obscures the part of the article that IMO is (or at least should be) of major interest to most of the HN audience. That point is that climate change is a generational issue:

"If you’re already in your mid-50s or later, and you’re lucky enough not to reside in any areas that are traditionally prone to hurricanes or flooding, you’ll miss the worst of our imminent destruction. But for those of us who are younger..., who hope to live long, healthy, happy lives — well, tough shit. ... While the AARP spends over $100 million on D.C. lobbyists every year protecting... Social Security and Medicare, no comparable institution exists to lobby on behalf of Mmillennials and “Gen Z,” the demographic groups that will face global warming’s worst consequences. We’ve been consigned to the sidelines, turned into spectators of the greatest disaster movie ever made."

So I am no longer submitting direct links to HN because I believe they are too constraining. From now on I am only doing text submissions with embedded links and a brief summary of the content and why I think it's relevant to HN. I think that if more people did this, the quality of the content on the home page would be improved. At least it's an experiment worth conducting.
You've hit the nail on the head. The journal's impact factor would be pitifully low. But you're quite correct that having the information available would save a great deal of time and money (and blood, sweat, tears, grief and anxiety).

The ability to publish negative results would be tremendously useful for doctoral students. I mean, a tremendous amount of science is negative results and nothing about dissertation research guarantees that your hypothesis will be proven by your data. This would ease a lot of the angst caused by publication requirements for doctoral students and would give them phenomenal writing practice on fairly low stress publications. There's merit here, without a doubt, but it doesn't fit in to the established hierarchy of academic research which is a massive issue. I'm a firm believer is reform of academic research, but that's an entirely different discussion...
Thanks, that's really useful. It answers a lot of the irritating little questions that Scala's flexible syntax gives you, like whether or not to use dots for method invocation. I see that Twitter has a document on the best ways to write Scala, which looks interesting: http://twitter.github.io/effectivescala/

This is my entry for a local contest(http://www.apps4halifax.ca/) in Halifax NS. Was hoping to get some suggestions for improvements or comments.
As a keen cyclist (and politically active in this area trying to get better infrastructure in Bath, UK), I have noticed that I seem to be surrounding myself with people that have similar view points (cars are bad for cities, think of the kids).

I have tried to bring in other views by following people, but it seems to only happen when one of the people I follow retweets an inflammatory tweet. I follow, get involved in the discussion then move on. Of course then I've noticed that most of my feed is pro-cycling. I've created my own filter bubble.

I should probably start looking to break out of this 'sub-conscious' filtering I appear to be doing although it would be interesting to have twitter recommend people I would find very annoying to follow.
The existence of apparent bubbles does not contradict the EMH.

I didn't find that link at all convincing, in particular the vague handwaving about bitcoin - because that is as-yet unproven and very uncertain I don't think it's a good example - why not use one of the many stock market busts? Booms and busts are not 'apparent bubbles' in any sense, they are all around us, and cause real movements in the markets regularly. They are a great illustration of markets behaving completely irrationally and becoming divorced from any efficient relationship between price and underlying or future value due to euphoria, panic, over-abstraction or obfuscation of assets and risk, monetary stimulus, corruption, cornering, rumour etc, etc. Sudden resets (often overreactions), and wild swings are the result, so much so that many of our markets have circuit-breakers which stop trading to attempt to discourage their natural movements.

There are a whole host of reasons why our markets are not currently anywhere close to perfect or efficient, and to simply assume they are and then attempt to cut the facts to fit the procrustean bed of market theory is not at all convincing. What is dangerous about the EMH to me is that it encourages a sort of worship of markets, which are seen as efficient and all-knowing, and which can never be gainsaid. In fact markets get things wrong all the time, they are pretty irrational quite a lot of the time, they are just the least-bad system we know.

If you believe the boom & bust cycle shows the market to be irrational, what is the EMH-disproving trading strategy?

Again, not believing the EMH is not the same as believing you can beat the market with short term trading, the two concepts are completely unrelated. I have no idea what sort of trading strategy you think would disprove EMH, but we're not talking about trading strategies but models for markets. Personally, I wouldn't trade short-term at all in stock markets, but do invest. I happen to mostly agree with the author here, but again, that has nothing to do with efficient markets.

The EMH is a postulation which makes extraordinary claims about markets in general, it does not need to be disproved, it needs to be proven in the first place by comparison with the real markets it claims to describe. Many leading economists (e.g. Greg B Davies) have pointed out flaws in it, and EMH is far from being a consensus.

Author doesn't seem to know what the difference between a sigint organization NSA/GCHQ and a Humint one is or even what the difference between an officer and a spy is.

Both GCHQ and NSA can point to successes as can all the major players in the spy game would Stalin have got the bomb so quickly without spies. Or the success of the XX committee. Or from the other side the Cambridge 5 where certainly effective.

And do you think binladen would not have been found and killed if it wasn't for spies run by CIA officers?

The track record of Warren Buffet and a few others is evidence that the EMH is imperfect. The rarity of Warren Buffet-level investors is evidence that it's still pretty accurate.

How does a boom and bust prove the EMH false? Could you explain the mechanics in detail?

Going back to your poker example, if top players in poker were rare and gains/losses seemed random, that would be evidence that Poker is mostly just luck.

Between the commit wording and his comment on IRC (https://twitter.com/ArmyOfBruce/status/406802499014627328) I read that as implicitly threatening Isaac's commit bit but that was wrong. I shouldn't have stated that: it would have been more accurate to describe it as confrontational rather than a threat.

> By the way, it's rather fatuous to refer to my comment as a 'spin attempt' just because I didn't reflexively grab my pitchfork and torch and run out to join the mob trying to crucify this developer as a incorrigible misogynist

I described it as spin because it focused on the initial commit & the grammar issues rather than the way Ben chose to escalate it. Your choice of quotes and commentary focused on the beginning rather than what happened afterwards, neatly omitting the actual focus of the discussion. Perhaps that was accidental but it sure looks like an attempt to minimize the offense before criticizing the response.
>And gasoline-powered vehicles of all sorts catch on fire all the time in collisions

Gasoline cars do not "catch on fire all the time in collisions". Not remotely.

It's unlikely the Teslas do, either. But Tesla's vehicles are both relatively novel, and real-world-untested and hence are both a news story and deserved of scrutiny.

Just like these drones.

Is contention with HN's ranking algorithm common? I've perused the "new" page a number of times, and generally interesting submissions (i.e. what HN finds interesting) DO make it to the front page.
Sorry, maybe I wasn't being clear. When I said "Doesn't pay more than you would have" what I meant was "Doesn't pay more [transactions costs e.g. fees and bid / ask spread] than you would have [had you just pursued an indexing strategy" In that light the current price of Berkshire Hathaway isn't particularly relevant because even if I just bought Berkshire stock I would still pay the spread. In fact the current B/A spread on BRK.A is 183218.7-174644 = 8574.7 which is considerably higher in percentage terms than a stock with more volume. Of course that's probably exactly how Uncle Warren wants it given he's let the price go so high with out a split.

Children have to go to school in the USA. But you can't force them to do well. Many kids don't want to learn for various reasons, and not all parents are a part of the process. The blame is then unfairly placed on the school system, and the kids end up quitting school as they get older.

I live in a poor area and I was in line at McDonald's and became angry that there wasn't a long line, but the line was moving very slowly. When I got to the cashier I realized the 20 year old girl they had working could hardly read and that's what was taking so long.

I ended up feeling bad for getting mad at the situation, I can't imagine not being able to read and what she must feel having to work there without being able to.

I was not hellbanned - where everything I posted was instantly dead.

To be honest the only thing I'm sure of is that I was slowbanned. I timed page loads 10 times with the slowbanned account and they averaged about 11 seconds. Then page loads with not being logged in averaged about 1 second. Then page loads with a new account averaged about 1 second as well.

The junky thing is that the account was almost 7 months old and had 3,324 positive karma but I guess I said something that ticked someone off:

Just in case you didn't see my sibling comment, see https://news.ycombinator.com/item?id=6834047. The IRC comment was where I saw the most threat:

Even with that, however, I probably shouldn't have described it as a threat – it's aggressive and confrontational but there's no explicit threat.
> And the danger is that it can polarise populations creating potentially harmful divisions in society.

I think we already see the effect of this. It gets harder for opposing sides to find common ground - from local to government level. People get more prone to critical commentary, claiming "hurt feelings" at first opportunity. Even here on HN a constructive debate is uncommon.
