Created December 11, 2020 20:47
Lol, old file I found, the evolution of my FizzBuzz attempts.
Array.from({ length: 100 }, (v, i) => [[15, 'fizzbuzz'], [5, 'buzz'], [3, 'fizz']]).find(x => (i+1) % x[0] === 0) || (i + 1)).reduce((a, o) => a += (o[1] || o) + "\n",'')
return
for(var i = 1; i< 101; i++){
console.log( (i%3 === 0 ? 'FIZZ' + (i%5 === 0 ? 'BUZZ' : '') : i%5 === 0 ? 'BUZZ' : i))
}
return
/*
for(var i=1; i<101; i++){

Raspberry pi setup wifi without keyboard/mouse
There's an easier way for the SSH and wifi:
* flash the card with etcher
* put empty file called "ssh" on SD card
* put "wpa_supplicant.conf" file on SD card
* insert SD card in Pi Zero W
You're done, Pi will boot with SSH enabled and will automatically connect to wifi.

My Node Semaphore code written in response to irc #node programming challenge
//-------------------------------------------------------
// QUESTION: Can you implement the Semaphore type?
//
// In systems programming, it is sometimes important
// to restrict the requests made to a given resource.
// The resource may be a CPU bound process, or a
// network resource. Controlling throughput to that
// resource can be challenging, but simplified through
// the use of a semaphore like primitive.

Block ssh
I don't like to use any third party tools. Hence I used a combination of ssh configuration and firewall settings. With the following solution an attacker is allowed to produce exactly 3 fault logins in 2 minutes, until he will be blocked for 120 seconds.
1) Add the following line to /etc/ssh/sshd_config
MaxAuthTries 1 #This locked me out of my server
2) Add the following firewall rules
