# As the "bufferbloat" folks have recently re-discovered and/or more widely
# publicized, congestion avoidance algorithms (such as those found in TCP) do
# a great job of allowing network endpoints to negotiate transfer rates that
# maximize a link's bandwidth usage without unduly penalizing any particular
# stream. This allows bulk transfer streams to use the maximum available
# bandwidth without affecting the latency of non-bulk (e.g. interactive)
# streams.

This program can be used to convert raw BGRA 8888 framebuffer to standard PNG file.

O(1) Block Propagation

The problem

Bitcoin miners want their newly-found blocks to propagate across the network as quickly as possible, because every millisecond of delay increases the chances that another block, found at about the same time, wins the "block race."

burn-btc: create a bitcoin burn address

By James C. Stroud

This program requries base58 (https://pypi.python.org/pypi/base58/0.2.1).

Call the program with a template burn address as the only argument::

#include <QtGui/QGuiApplication>
#include <QtQml/QQmlApplicationEngine>
#include <QtWebEngine/qtwebengineglobal.h>
 
int main(int argc, char *argv[])
{
  QGuiApplication app(argc, argv);
  QtWebEngine::initialize();
  QQmlApplicationEngine appEngine;
  appEngine.load(QUrl("main.qml"));

Intro

Just some FYI, to get started:

• I'm using a 16 GB Sandisk SD card.
• I have a model B Pi, 512 MB RAM (not really relevant, thought I'd mention it).
• Monitor and keyboard connected to the Pi itself, for now.
• Network working, internet access.
