Search Results for "memory"

A differential compresor (or a binary diff) for huge files. Unlike other tools, e.g. xdelta3, it searches for matching data through the whole source file, even if it weights several gigabytes, while using much less memory (with default configuration approx 25x less than the size of the source file). Output files are not compressed, so you can use any compressor you like with great results. It is quite fast for very similar files (about the speed of hdd, however it reads input files twice) and not much worse on files with lots of differences.

...It compresses JPEG files at a rate of 5 megabytes per second and decodes them back to the original bits at 15 megabytes per second, securely, deterministically, and in under 24 megabytes of memory. We have used Lepton to encode 16 billion images saved to Dropbox, and are rapidly recoding our older images. Lepton has already saved Dropbox multiple petabytes of space. At Dropbox, the security and durability of your data are our highest priorities. As an added security layer, Lepton runs within seccomp to disable all system calls except read and write of already-open file descriptors. ...

A simple project for use with SDL that loads a zipfile into memory and automatically converts all known files (such as text, graphics, fonts, and sounds) into data that is ready to be used in a game or multimedia project. It is the SDL equivalent of an A
