Fibur

Fibur is a library that allows concurrency during Ruby I/O operations without needing to make use of callback systems. Traditionally in Ruby, to achieve concurrency during blocking I/O operations, programmers would make use of Fibers and callbacks. Fibur eliminates the need for wrapping your I/O calls with Fibers and a callback. It allows you to write your blocking I/O calls the way you normally would, and still have concurrent execution during those I/O calls.

Example

Say you have a method that fetches data from a network resource:

amscotti

require "rubygems"
require "sinatra"
require "haml"
require "mongo_mapper"

class Shorten
  include MongoMapper::Document
  
  key :url,        String
  key :shorten_id, String

isa

Question: Convert following into the latter data structure in less than 30 lines:

List:
  A, B, C
  A, C, E
  E, F, D
  D, A, J
  E, D, J

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

andkerosine

$stack, $draws = [], {}

def method_missing *args
  return if args[0][/^to_/]
  $stack << args.map { |a| a or $stack.pop }
  $draws[$stack.pop(2)[0][0]] = args[1] if args[0] == :<
end

Hello software developers,

Please check your code to ensure you're not making one of the following mistakes related to cryptography.

I. General Mistakes

• Writing your own home-grown cryptography primitives (For example: Mifare Classic)
  • Exception: For the sake of learning, but don't deploy it in production.
• Using a fast hash function (e.g. MD5, SHA256) for storing passwords. Use bcrypt instead.
• Not using a cryptographically secure random number generator

This wrapper automatically sets the RUST_SRC_DIRECTORY environment variable for whatever rust compiler is currently active, automatically creating a new checkout whenever necessary. This should be compatible with all of the multirust-alike tools, but it has only been tested with rustup.rs

Installation

Simply place this somewhere on your path before the main racer binary and set the execute bit.

Uninstallation

Before

yum install -y systemd-networkd
modprobe macvlan # make sure this returns no errors

Put config files in place

eth0.network and mac0.{netdev,network} go in /etc/systemd/network/

# NAS IP: 192.168.1.10 in this example
# DHCP scope reservation for macvlan: 192.168.1.210/28 (Details below)
## Network:   192.168.1.210/28
## HostMin:   192.168.1.211

## Hosts/Net: 14

# Create a Synology macvlan0 bridge network attached to the physical eth0, and add the ip range scope (sudo)
