FreeBSD: Wi-Fi: suggested adapters

There are numerous suggestions, I'm not yet aware of any other collection.

If the list below grows to become useful, someone might like to adapt its content for the FreeBSD wiki.

Simple file/stream encryption using OpenSSL

Create and store a 512-byte random encryption key named secret:

$ mkkey secret

Encrypt the contents of file with the secret key and write it to file.enc:

$ encrypt secret < file > file.enc

We've seen lots of Ruby feature requests about converting an Enumerable to a Hash: to_h, map_hash, map_to, each_with_hash, etc. Let's look at one common, simple case of this.

Building a key/value mapping from a collection of keys is awkward. We commonly see Hash[*collection.map { |element| [element, calculate(element)] }] or collection.each_with_object({}) { |element, hash| hash[element] = calculate(element) }. Both are verbose. They require boilerplate code that's not relevant to the programmer's intent: to associate an enumerable of keys with calculated values.

Ruby has the idea of an association already: a key and value paired together. It's used by Array#assoc to look up a value from a list of pairs and by Hash#assoc to return a key/value pair. Building up a mapping of key/value pairs is associating keys with values.

So! Consider Enumerable#associate which builds a mapping by associating keys with values:

# Associate filenames with URLs. Before:

rkh

# encoding: binary

# Removes any bytes from a string that are not valid UTF-8
class Cleaner
  attr_reader :bytes, :buffer, :outstanding

  def self.clean(str)
    new.tap { |c| c << str }.to_s
  end
