Get your first two months of CuriosityStream free by going to http://curiositystream.com/crashcourse and using the promo code “crashcourse”. So last episode we talked about some basic file formats, but what we didn’t talk about is compression. Often files are way too large to be easily stored on hard drives or transferred over the Internet - the solution, unsurprisingly, is to make them smaller. Today, we’re going to talk about lossless compression, which will give you the exact same thing when reassembled, as well as lossy compression, which uses the limitations of human perception to remove less important data. From listening to music and sharing photos, to talking on the phone and even streaming this video right now the ways we use the Internet and our computing devices just wouldn’t be possible without the help of compression.

We will draw the huffmans coding tree structure, assign uniqque binary values to charachters based on their frequencies or weights. Following is the question that we are going to solve: Q) Given a string AAAABBCD, Generate the Huffman code tree?

The Science and Application of Data Compression Algorithms
 
40:28
Data compression is a ubiquitous aspect of modern computing, but not necessarily well-understood or optimally implemented. This talk will cover fundamental compression concepts that every software engineer working with the storage or transmission of data should understand. We will explore the inner workings of several popular compression algorithms and how these algorithms work for different types of data, including situations where compressing data might not actually be beneficial. * This talk description can be compressed by 46%, from 569 bytes to 309 bytes. About the Speaker: Andrew Olson is an architect on the Big Data Platform team, where he helps design and build frameworks for Cerner's cloud-based solutions using open source projects such as HBase, Crunch, Storm, and Kafka. After graduating from Iowa State University in 2001, Andrew joined Cerner as a software engineer on the team that is now known as Millennium Foundations. An avid soccer fan, you can find him in the South Stand at most home Sporting KC games. This talk was given at DevCon, Cerner's internal engineering conference.

Intel® ISA-L Compression Algorithms | Intel Software
 
02:49
The Intel® Intelligent Storage Acceleration Library (Intel® ISA-L) includes algorithms for compression and decompression. DEFLATE compression algorithms traditionally use either a dynamic or static compression table. Use of a dynamic table achieves the best compression at a higher processing cost, while use of static tables increase throughput at a lower compression rate. Intel ISA-L semi-dynamic compression comes close to getting the best of both worlds. In addition, Intel® ISA-L offers a version of the decompression (inflate) algorithm which substantially improves the decompression performance. Learn more about how Intel ISA-L compression and decompression functionality can improve the performance of your software defined storage application on Intel® architecture.
