tejastank / derhuff.c
Created March 31, 2021 05:14 — forked from danielrothfus/derhuff.c
A very simple Huffman implementation I wrote for bit-by-bit I/O practice.
/** \file derhuff.c
\author Daniel Rothfus
\version 1.0
\brief A really simple Huffman implementation.
Derhuff is a simple utility to compress files using the Huffman coding scheme.
To compress a file, it analyzes the frequencies of all the bytes in the file
and builds a tree using these frequencies, which it writes to the output. With
this tree, the program then converts each byte of the input to the path to get
to the corresponding leaf in the tree. To decode, it just reads the tree from

A simple Python 3 script to brute force a minimal solution to the Rush Hour game.
# Rush Hour Solver
# rushsolver.py
# Daniel Rothfus
# This is a fairly slow brute force solver for the game Rush Hour. This solver
# was inspired by http://acm2013.cct.lsu.edu/localdoc/problems-scripting/1.pdf
# Please note that this solver was made for Python 3, not Python 2.
#
# To use this script, first input the character that will represent the special
# car to remove from the right side of the grid in the following board. Next,
# input the board in ASCII art on the next 6 rows. Periods should be used to

NGINX tuning for best performance

Moved to git repository: https://github.com/denji/nginx-tuning

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.
