Norway allows you to see / search almost everyone's personal tax record (including name, birth year, postal code, net income and net wealth). You can do this online here: https://w…

Even worse, there are some different PyPI packages with the same import name. For example, `import snappy` is probably referring to the compression library https://pypi.org/project…

Be careful, doing str(num) requires python to convert the binary representation it has num stored as to a decimal. (C)Python implements a quadratic time change of basis algorithm. …

1. Make it work 2. Make it understandable 3. Make it performant (if too slow).

To be exact, the hard limit is: you cannot delete more than 10% of your organization's accounts (capped at 200) via AWS Organization within a 30 day rolling window. You can always …

This argument only applies to functions on a compact domain. So we should only consider trying to approximate sin(x) when x is in [0, 1], for example.

A number of assumptions seem to be missing from this article. Since the author is using the sigmoid function which is smooth, this argument actually only applies to approximating s…

That may have been the case in 2011 when that article was written, but I have just tested this now and my facebook does not accept my password with the case reversed by having the …

Similarly there are many sites that allow you to log in using `your password` or `your password`.swapcase() (for example, Password123 or pASSWORD123). Automatically trying a varian…

That's great. However the method that you use to find the canonical representative [1] is quadratic (when the string has length N, there are N rotations and for each rotation you n…

Unlike many of his videos which are made using KSP, this RTLS Abort Challenge video was made using Orbiter 2016 Space Flight Simulator from UCL http://orbit.medphys.ucl.ac.uk/

Mathoverflow has their "long-open problems which anyone can understand". This includes things like the integer brick problem: Is there a brick where all its dimensions (width, heig…

The largest eigenvalue of (A - k)^{-1} is 1 / (x - k) where x is the smallest eigenvalue of A that is larger than k. So by using this technique on (A - k)^{-1} for various values o…

I have to say how confusing I found this demo without a US keyboard. In section 10 I spent far too long pressing Shift+3 and wondering why it wouldn't progress even though I was pr…

The first four digits of arXiv papers links are the year and month of submission (to the arXiv). Just from this link I can tell that this was submitted in September 2016.

There are no other factors less than 2^32. You can see my other comment for details on verifying this.

The following Sage script shows that p has no prime factors less than 2^32 other than 271 and 13597: p_list = [0xCC, 0x17, 0xF2, 0xDC, 0x96, 0xDF, 0x59, 0xA4, 0x46, 0xC5, 0x3E, 0x0…

Sorry, but how did you compute this? Do you know that there are less than 10^85 board positions which have a symmetry?

Just to point out: entering 1000^6 gives 999,999,999,999,999,900.
