If solar panels are the bottleneck then they shouldn't be wasted on people's rooves, either. They should put them in a big field where the electricity company can point them in the optimal direction, perhaps with a device to redirect them during the day, or mirrors, and look after them properly: clean them, if that helps, or whatever.

How is this sort of thing not abused?

Say I generate logs at say 1 GB/hr and store them in files named `logs.$(date +%Y%m%dT%H)` and I have it set up to take snapshots every 4 hours and delete files older than 5 hours, then I could have essentially unlimited storage and only ever pay for 5 GB/month?
a very efficient solar panel would be flat and the gains would be offset by bad aerodynamics
> A more effective solution would be to have a carport with a solar panel roof (10~15m2)

Right. Or from a pure economics point of view, put the solar panels literally anywhere else in the world other than on top of the moving vehicle that is sensitive to aerodynamics, weight and structural integrity. Deal with the small transmission losses from the grid. Rely on charging stations at home, work or other businesses. The last part is the only piece that isn't reliable at the moment, but is only getting more so.

That is not actually the way to define e^x for complex numbers. There are a few ways you can do so. The most natural way is as the unique solution to the differential equation

df/dx = f

The solutions are e^x + const; requiring f(0) = 1 gives you the choice const = 0.

Another way to define it is as the infinite series

e^x = \sum_{i=0}^inf x^i/i!

It is pretty easy to show this definition is equivalent to the previous one. A third way is as

lim_{n -> inf} (1 + x/n)^n

This definition comes from the intuition that e^x represents the limit of continually compounding interest. As before, it is pretty easy to show that it is equivalent to the previous two.

In any case, all these definitions extend directly to complex values of x. The fact that

e^{ix} = cos(x) + i sin(x)

holds (and hence Euler's identity holds) is a consequence of a more natural definition, not the typical definition.

How to Develop Your Brand Strategy
Most developers I know are not named inventors on any patents.

It's not so much about understanding the space, it's about the mental availability of examples used to estimate the general state of the world.

People who watch TV news regularly overestimate the crime rate. Why? Because TV media focuses on the dramatic and attention-grabbing -- "if it bleeds, it leads". No effort is made to present a statistically valid sample of reality. Nobody is publishing "little old lady walks home safely for two thousandth time".

Similarly for patents. There are millions. Which ones get press? It's not a perfectly random sample, what we see is the absurd and outrageous examples, ones which deserve criticism and anger. But if you base your estimate of the entire system on examples chosen specifically because they will arouse anger, then you have an inaccurate estimate. Because "patent for neat idea lives quiet life until expiry" or "patent amicably licensed on reasonable terms" or "patent application invalidated by prior art during examination" don't make it to the front page of HN.

If you explored the problem domain, starting with an understanding of trigonometry and calculus, it will naturally emerge as a result. It was not arbitrarily defined.

Imaginary numbers were not arbitrarily defined either, they precisely describe an actual phenomenon.

At a certain level, it is difficult to distinguish between "the reality we decided is true" for math vs. "the reality that must be true underneath". If you accept empiricism, such that you trust observations we make about the physical world, this problem becomes irrelevant to this discussion.

> If the top speed is 160 km/h, then a good EMU has a stop penalty of about 45 seconds, a powerful electric locomotive about 135 seconds, and a diesel locomotive around 190 seconds. With short dwell times coming from level boarding and wide doors, EMUs completely change the equation for local service and infill stops, making more stops justifiable in places where the brutal stop penalty of a locomotive would make them problematic.

There are 2 schools of thought on the Y2K bug, and the one you left out was that quite a lot of money was spent fixing bugs prior to the year 2000, which helped ensure that it was a minor event, with minor failures, instead of a bigger problem. There are computer systems we are even just now starting to hear had major problems that were addressed. Yes, there were people hyping it like crazy, and the average personal computer was not really at risk of anything major happening. But there were serious concerns that were addressed prior to 2000.

Also, it's likely the 9/11 attacks had less of an impact because of redundancies and backups put in place for the Y2K bug.

I simply don't like DoH because I use a DNS provider that I have chosen - OpenDNS - specifically because they log my DNS queries and let me see that log. I don't mind DNS lookups from my network being logged, as long as the provider does accurate, uncensored DNS lookups. It's helped me find domains to block such as tracking domains used by IoT devices that I can't configure myself.

I have my router directing all DNS traffic to OpenDNS so these devices can't pick their own servers, any outbound requests on port 53 will be redirected. If they start using DoH/DoT, I can't do that so easily. I'd have to start monitoring outbound traffic and do hostname resolution on the IPs.

I think the privacy argument for DoH in the browser is fairly weak, since doing a DNS lookup is not really an indication of, well, anything really. No matter what domain it was, there's no indication that the user intended to visit a website or use a service on that domain, it could be as simple as a lookup to load an embedded image in a spam email. The only good usage of it is to prevent censorship via DNS.
Sorry! Can you help me how to get karma point??
We can look at history:

1. e was discovered in 1618

2. i was introduced around 1637

4. calculus was formalized by Newton in 1687

3. derivatives of sine and cosine were discovered in 1722

4. de Moivre's formula (cos x + i sin x) ^ n = cos nx + i sin nx was discovered in 1730

5. Eulers fornula e ^ ix = cos x + i sin x was discovered in 1748 by using Taylor series (requires their derivatives).

So we knew about e and i more than a century before Eulers fornula.

However we discovered it pretty soon after we started applying calculus to trigonometrical functions. Also we can note that it is a strictly more powerful than de Moivre's formula since it shows that we can easily add angles just by multiplying their complex representations, so it is not just a simplification of old knowledge.

So it seems like the discovery of Euler's fornula actually did help with working with rotations. However it was done during a time when we were still exploring the applications of Calculus so there were a lot of low hanging fruit like this to pick.

So to directly answer your question, e was not created to perform 2D rotations, instead we discovered that putting i inside of e makes 2D rotations simple. But the actual important identity you care about is that you can add angles by multiplying which is easy to prove using eulers fornula:

(cos x + i sin x) * (cos y + i sin y) = cos (x + y) + i sin (x + y)
EDIT: This is totally wrong. I haven't had my morning coffee yet. H_n - H_(cn) ≈ constant, not diverging (for 0 < c ≤ 1). :)

The problem is that all of these little errors add up to give you a logarithmic slowdown. In particular, the solution proposed in this comment is still Ω(k log k) (where k is the number of elements drawn), which is slower than the algorithm's proposed solution of O(k).

What would make it a compelling answer?

I have noted elsewhere that the outrageous examples are publicised because they are outrageous, but that doesn't make them a valid statistical sample of all software patents.

Patent lawyers need to understand the material well enough to draft the claims and perform clearance searches. If they can't do that then they are sailing towards failing their fiduciary duty; a lawyer anxious to hold onto their bar membership would refer you to another one with a speciality in the field.

If I go to a criminal lawyer and ask for tax help, they will refer me to a tax lawyer. If I go to a chemical engineering patent lawyer to talk about a compression algorithm, they will refer me to a patent lawyer who specialises in software and computing.

We can compute a random k-size subset of {0..n-1} as rndsubset(0,k,n), where

rndsubset(i,0,n) = {}

rndsubset(i,k,n) = {i} union rndsubset(i+1,k-1,n) with probability k/(n-i), rndsubset(i+1,k,n) otherwise

This however takes on average n/k time per element, which is prohibitive when n >> k.

The probability of {h} being the next chosen element in rndsubset(i,k,n) is k/(n-h) * Prod_{i<=j<h} 1-k/(n-j), which is sampled directly in constant time by Vitter.
Past winter, I had to deploy a new version of a package that was used by a lot of our applications (at least 5 apps, some for our customers, and some internal ones).

Because it was a "simple" package, we did not have any deployment system ready, and deploying was just SSH/SCP commands that created a directory with the package version and upload my dist. I forgot to bump the package version, and ended up wiping a working and in-use package. The problem is that this package can only work up to a specific angular version (which wasn't set in the package.json, so my build installed the wrong one), therefore the only thing that our applications were producing was a blank page.

And because I had wiped the original package, I had no way to know which angular version we needed, and we had to find a cached version to get it, by reading the angular license comment in the minified code. The shittiest 5 mins of my life, even though I'm sure no one noticed it.

What I learned from this : don't speak with someone else while deploying, huge focus loss.

PS : The company is an ISP.

An easy way to randomise a list is the following:

import random

list = [0,1,2,3,4,5,6,7,8,9]
length = len(list)

for i in range(1,length):
j = length - i
k = random.randrange(j+1)
list[j], list[k] = list[k], list[j]

print(list)
[3, 9, 6, 4, 7, 8, 5, 1, 0, 2]

The randrange(j) can be done quickly by finding the smallest power of 2 above j and then picking randomly below it until you get an answer less than j.

First: because it's really hard to pinpoint exactly who is responsible for something like this in a large organisation. Is it the CEO? They are unlikely to know enough about French taxation. Is it the local accountant? That's probably a team as well.

Second: Cases like this often arise from different interpretation of laws that are all at least plausible. Companies may tend to be somewhat too optimistic in their interpretations, but it's rare, at least at that size, that they actively try to commit tax fraud.

Third: It is the company that profits from the offense, so it's only fitting to apply any sanctions to it.

Fourth: Making this criminal law would raise the required standards of evidence to a level where few of these cases could ever be prosecuted.
