var, let, const 차이점은?

• var는 function-scoped이고, let, const는 block-scoped입니다.

• function-scoped와 block-scoped가 무슨말이냐?

var(function-scoped)

난해한 혀엉... 언어 v0.4.5

• …(U+2026), ⋯(U+22EF), ⋮(U+22EE)는 모두 .(U+002E)가 3번 연속으로 나열된 것과 같은 것으로 봅니다.
• "한글 음절 문자"는 가(U+AC00) 이상 힣(U+D7A3) 이하의 유니코드 문자들을 의미합니다.

스택

• 스택의 모든 원소는 유리수 또는 NaN으로 이루어져 있습니다. 분모가 1인 유리수를 편의상 정수라고 칭합니다.
• NaN은 특수한 숫자처럼 취급됩니다. 어떠한 연산을 하더라도 그 연산에 NaN이 있을 경우 그 연산의 값은 NaN이 됩니다.

OverEncrypt

This is a guide that I wrote to improve the default security of my website https://fortran.io , which has a certificate from LetsEncrypt. I'm choosing to improve HTTPS security and transparency without consideration for legacy browser support.

WARNING: if you mess up settings, lose your certificates, or decide to no longer maintain HTTPS certs, these steps can and will make your domain inaccessible.

I would recommend these steps only if you have a specific need for information security, privacy, and trust with your users, and/or maintain a separate secure.example.com domain which won't mess up your main site. If you've been thinking about hosting a site on Tor, then this might be a good option, too.

The best resources that I've found for explaining these steps are https://https.cio.gov , https://certificate-transparency.org , and https://twitter.com/konklone

# Implementation of a simple MLP network with one hidden layer. Tested on the iris data set.
# Requires: numpy, sklearn>=0.18.1, tensorflow>=1.0

# NOTE: In order to make the code simple, we rewrite x * W_1 + b_1 = x' * W_1'
# where x' = [x | 1] and W_1' is the matrix W_1 appended with a new row with elements b_1's.
# Similarly, for h * W_2 + b_2
