abrezas··on Oceans hit highest temperature on record
You are looking at the acceleration but without looking at the initial state.

A more fair metric would be Co2 emissions/person and I’m getting

abrezas··on Made in the USA: Socialism for the Rich. Capitalism for the Rest
Wikipedia: "Socialism is a political, social and economic philosophy encompassing a range of economic and social systems characterised by social ownership of the means of production and democratic control or workers' self-management of enterprise".

Which is not "...characterised by government giving handouts".

abrezas··on Basic Income Experiment in Finland will continue until the end of 2018
I felt the english version was ambiguous so I read the original finnish version. It says that press reports that the trial is aborted earlier than planned is false, and for the time being there is no decision to extend it.

abrezas··on AMD's revenue rises 18%, but margin forecast disappoints
What do you mean by more than 100% margin?

If you sell something for 150$ and it cost you 30$ your gross margin is (150-30)/150=80%.

abrezas··on Merging vs. Rebasing
The problem is not if someone merges a PR before you push, but if someone branches off of the current tip of master, works on it, you remove that tip, and your colleague now is based on a history that doesn't exist, has to resolve your conflicts.

abrezas··on Fictionalism in the Philosophy of Mathematics [pdf]
I don't believe they are entirely independent, but there's nothing you can look outside your window that will change any mathematical theorem.
abrezas··on Fictionalism in the Philosophy of Mathematics [pdf]
But if at some point further decimals cannot be experimentally proven to be right, at best you can say "pi is such and such for such precision" and any definition that gives the same number up to that precision must be accordingly accepted. Otherwise you need to demonstrate an experiment that uses further precision.

But we don't do that, and that's why mathematics don't have to do with experience, they are an entirely different tool that also happens to be useful in experimental science.

abrezas··on Fictionalism in the Philosophy of Mathematics [pdf]
At some point mathematical objects are defined with meta-mathematical definitions (axioms etc), so we can accept definitions based on those terms.

But in any case. You obviously do not believe that mathematical objects exist in the first place and it the question is ill posed based on your concept of reality and existence.

That's understandable, but the debate is about which is the right definition of existence reality etc. If you are not interested in this discussion and know the answers then you have nothing to gain from this paper or this discussion.

abrezas··on Fictionalism in the Philosophy of Mathematics [pdf]
The concept of prime numbers and the prime numbers themselves is a different thing.

Unicorns don't exist but statements about them aren't meaningless. Fictionalism accepts the concept of mathematical entities but denies their existence in the real world.

abrezas··on Fictionalism in the Philosophy of Mathematics [pdf]
If a mathematical statement did not have a corresponding experimental test would you dismiss it? What about those?
abrezas··on Fictionalism in the Philosophy of Mathematics [pdf]
You think that they are confusing the term exists but the reality is that what "exists" means is very hard to define.

Where is the line between abstract objects and the real world you mentioned? Can you give a rule that separates the two?

Do black holes exist? Electrons? Magnetic fields? Is one of these a model but doesn't really exist?

abrezas··on Ask HN: Open problems in finance?
One of the problems with the Canadian tax law, was that Canada has to remain competitive to the same-language speaking country south of its borders that has a bigger and more advanced stock exchange. It is explained in the last section of your second link.

The same problems will not be necessarily manifested if the law is applied in the US, especially if Canada has similar laws. However, the points of the first link seem to hold.

We already have regulations for things like safety, so it all depends on how seriously you think of the matter, and how well you think the government will be able to regulate it.

abrezas··on Thinking about wealth taxes
It isn't at all different. The amount of money the entrepreneur didn't invest into the next company or spent, is the amount he will be taxed as wealth.

This way, the entrepreneur has incentive to spend it or do more investments instead of keeping it in the bank where it would be taxed.

This incentive leads to inequality decreasing by the economy being more active.

abrezas··on ES7 Proposal: The Pipeline Operator
it's very common in javascript to have chained methods, to be able to do things like

    _(array)
    .compact()
    .map(function(x) {
       return x * x;
    })
    .filter(function(x) {
        return x > 100;
    }).value()
(example from underscore/lodash)

The problem with this is to be able to add a custom function to this pipeline, you have to extend the prototype of the library with your own functions, or re-implement it.

Extending the prototype is considered bad practice for a lot of reasons, for example due to polluting code in other modules or upstream changes breaking your code.

If instead of chaining methods we chained functions we are left with this awkward syntax:

    custom(filter(map(compact(array), function(x) {
         return x * x;
    }), function(x) {
         return x > 100;
    }));
it's much cleaner to write it like this:

    compact(arr)
    |> map(function(x) {
        return x * x;
    })
    |> filter(function(x) {
        return x > 100;
    })
    |> custom

abrezas··on Greeks Reject Bailout Terms
greece had primary surplus last year http://www.globalizedblog.com/2015/02/greeces-primary-surplu...
abrezas··on Greeks Reject Bailout Terms
For me, there are several reasons why the rest of the eurozone should help Greece get back on its feet, rather than only give it more loans:

1) Due to being in the monetary union, Greece is not able to print more money, devalue its currency or other monetary policies to help its economy. Greece is paying the price of being in a monetary union, and it should either get help from the other members of that union, or it is not really a union.

2) Also, take into account that Germany and other countries are benefitting from this monetary union by being able to use a currency that is devalued due to the poorer countries, and therefore is able to increase its export.

3) Much of the bailout went into the banks of other eurozone members therefore helping them as well.

4) Do not forget that Greece if not in the eurozone would be able to default on its debts, live on the primary surplus it is now generating and when it is considered a good debtor to get loans again. Instead of having to exit the eurozone (which would be a bad sign for the whole union) and default on its debts (which would mean other countries losing money) and THEN grow, it may be beneficial to everyone to do a debt restructuring.

5) Greece is paying an interest on the loan given to them to be able to pay the older debts to the ECB and others. They are not able to pay that interest on the subsequent loans and are asking to be able to use that for economic growth to pay the older loans! In a sense, you can see that as debt restructuring, which can also happen in other ways. This way creditors will also get their money back, altough restructured or payed later.
