A bineutrino is an excited bound state of two neutrinos that occurs once per year per galaxy and lasts about 10^-36 seconds. Normally they aren't useful, but a type-IV civilization is able to create a swarm of bineutrino collectors that can stabilize one temporarily until hopefully a third neutrino reacts with the existing bineutrino. The resulting trineutrino lasts much longer and is very likely to catalyze further collisions, creating a hyperneutrino, a particle the size of a small star.

Autocorrect is the most hated thing of all time (after Java, Comic Sans MS, and iOS)

So why would we want that

Destructible Lemon

probably with some variance. I kinda feel like I did something wrong

MD XF

Doesn't that also depend on the number of letters in my name?

user165474

Given the number of distinct characters in your name n, there are 26-n characters in the final output string. Assuming that the number of distinct non-whitespace characters in your random string is 26-n, then we can obtain the following:

user165474

(wait for a couple hours while I try to figure this out)

user165474

12:09 AM

--- BEGIN MATH STUFF ---

user165474

Let n be the number of distinct characters in your name.

user165474

Let o be the number of characters in your output.

user165474

All non-letter characters shall not be considered for simplicity.

user165474

Additionally, case-insensitivity is assumed.

user165474

Then, the probability of this happening is:

Q: Simple encryption for people on a byte budget

Overview Your goal is to implement RC4 encryption. RC4 encryption, invented by Ron Rivest (of RSA fame), was designed to be secure, yet simple enough to be implemented from memory by military soldiers on the battlefield. Today, there are several attacks on RC4, but it's still used in many places...

e.g:

Greasemonkey

Greasemonkey is a Mozilla Firefox extension that allows users to install scripts that make on-the-fly changes to web page content after or before the page is loaded in the browser (also known as augmented browsing). The changes made to the web pages are executed every time the page is viewed, making them effectively permanent for the user running the script. Greasemonkey can be used for customizing page appearance, adding new functions to web pages (for example, embedding price comparisons within shopping sites), fixing rendering bugs, combining data from multiple web pages, and numerous other...
