# Huffman Coding
Top Podcast-Folgen
Aktualisiert:
In computer science and information theory, a Huffman code is a particular type of optimal prefix code that is commonly used for lossless data compression. The process of finding or using such a code is huffman coding, an algorithm developed by David A. Huffman while he was a Sc.D. student at MIT, and published in the 1952 paper "A Method for the Construction of Minimum-Redundancy Codes".
The output from Huffman's algorithm can be viewed as a variable-length code table for encoding a source symbol (such as a character in a file).

HPR4647: UNIX Curio #7 - Compression
This series is dedicated to exploring little-known—and occasionally useful—trinkets lurking in the dusty corners of UNIX-like operating systems.
In UNIX Curio #4 (
HPR episode 4617
), I teased the subject of file compression. Today I'm circling back to that.
The history of data compression goes…

007: Jake Wharton on Testing, SqlBrite, NotRxAndroid, RxJava and Much More
In the final part of this two-part segment, we continue our talk with Jake Wharton. We dive right into the topic of testing. Jake then talks about his approach to testing apps in Android and the different languages that he finds interesting. We then move on to RxJava, NotRxAndroid, SqlBrite and man…
