Interesting Snippets from 2021-07-27

• GitHub - inikep/lzbench: lzbench is an in-memory benchmark of open-source LZ77/LZSS/LZMA compressors

  lzbench is an in-memory benchmark of open-source LZ77/LZSS/LZMA compressors. It joins all compressors into a single exe. At the beginning an input file is read to memory. Then all compressors are used to compress and decompress the file and decompressed file is verified. This approach has a big advantage of using the same compiler with the same optimizations for all compressors.

• Silesia Corpus

  The intention of the Silesia corpus is to provide a data set of files that covers the typical data types used nowadays. The sizes of the files are between 6 MB and 51 MB. The chosen files are of different types and come from several sources. In our opinion, nowadays the two fastest growing types of data are multimedia and databases. The former are typically compressed with lossy methods so we do not include them in the corpus. The database files, osdb, sao, nci, come from three different fields. The first one is a sample database from an open source project that is intended to be used as a standard, free database benchmark. The second one, sao, is one of the astronomical star catalogues. This is a binary database composed of records of complex structure. The last one, nci, is a part of the chemical database of structures.
