I really like your description. I see now that if the compression is just removing same value byte strings how it really can be truly lossless. As someone who has had to deal with it I'll say that the extra intense radiation from sunspots really does matter. and cosmic rays are ignored only at peril.
Most compression algorithms are far more than "removing same value byte strings". Check out "huffman encoding" for example. I've never had a lossless compression program corrupt my data. Given your extreme mistrust of compression algorithms, it seems that you don't realize how much compressed data you deal with on a regular basis.
tar.gz, gzip, zip, rpm, initramfs, kernel, web pages, etc.
My experience with crc32 was in a hardware implementation. We needed good data integrity and the memory controller chip we chose had crc32 built in. I forget how many bits we added to each word to save the check bits, but I think it was four. I can imagine the uproarious laughter that would result if someone at a gathering of PC folks suggested that new memory modules should include extra bits to support hardware crc.
You mean like ECC RAM? _______________________________________________ test mailing list -- test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to test-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/test@xxxxxxxxxxxxxxxxxxxxxxx
