Edit There appears to be a better LZW solution that handles Unicode strings correctly at http://pieroxy.net/blog/pages/lz-string/index.html (Thanks to pieroxy in the comments). I don’t know of any gzip implementations, but the jsolait library (the site seems to have gone away) has functions for LZW compression/decompression. The code is covered under the LGPL.
tar in itself just bundles files together (the result is called a tarball), while zip applies compression as well. Usually you use gzip along with tar to compress the resulting tarball, thus achieving similar results as with zip. For reasonably large archives there are important differences though. A zip archive is a collection of compressed files. A gzipped tar is a compressed collection (of uncompressed files). Thus a zip archive … Read more
Mixing String and byte[]; that does never fit. And only works on the the same OS with same encoding. Not every byte[] can be converted to a String, and the conversion back could give other bytes. The compressedBytes need not represent a String. Explicitly set the encoding in getBytes and new String.
Compression algorithms almost always have some form of space overhead, which means that they are only effective when compressing data which is sufficiently large that the overhead is smaller than the amount of saved space. Compressing a string which is only 20 characters long is not too easy, and it is not always possible. If … Read more
I need to create a method that receives a String and also returns a String. Ex input: AAABBBBCC Ex output: 3A4B2C Well, this is quite embarrassing and I couldn’t manage to do it on the interview that I had today ( I was applying for a Junior position ), now, trying at home I made … Read more
Here is a quite nice guide how to add support for pre compressed static content to apache with fall-back to gzip
I have installed mod_brotli on my WHM server via easyapache 4 – html, css, js files etc are all being compressed. I then came across this in the offocial docs – https://httpd.apache.org/docs/2.4/mod/mod_brotli.html#precompressed I have since added this to my Post VirtualHost include file in WHM (post_virtualhost_global.conf) instead of htaccess as I want this to be server … Read more
