Finally, run zipmix on the collection of archives. Since different zip tools are better on different files, zipmix picks the best compressed version of each file from each of the archives and produces an output which is smaller than any that any of the zip tools could have produced individually.
You should note however that this is not guaranteed to work any kind of magic on your files. Certain types of data simply do not compress very well, like JPEGs and MP3s. These files are already compressed internally.
Let's take six kernel trees one version apart as a tarball, linux-2.6.31 to linux-2.6.36. These will show lots of redundant information, but hundreds of megabytes apart, which lrzip will be very good at compressing. For simplicity, only 7z will be compared since that's by far the best general purpose compressor at the moment:
These are benchmarks performed on a 2.53Ghz dual core Intel Core2 with 4GB ram using lrzip v0.5.1. Note that it was running with a 32 bit userspace so only 2GB addressing was posible. However the benchmark was run with the -U option allowing the whole file to be treated as one large compression window.
Top performers (based on compression) in this test are PAQ8 and WinRK (PWCM). They are able to compress the 300+ Mb testset to under 62 Mb (80% reduction in size) but take a minimum of 8,5 hour to complete the test. The number one program (PAQ8P) takes almost 12 hours and number four (PAQAR) even 17 hours to complete the test. WinRK, the program with the 2nd best compression (79.7%) takes about 8,5 hours. Not surprisingly all mentioned programs make use of a PAQ(-like) engine for compression. If you have files with embedded images (e.g. Word DOC files) use PAQ8, it will recognize them and separately compress them, boosting compression significantly. All mentioned programs (except WinRK) are free of charge.
Your best bet here seems to be trial and error. Try all your available compression techniques on each file and pick the best to put on your website. Luckily computers do this sort of thing pretty fast and don't get bored. You could write a simple script to automate the process so it would be "relatively painless".
Nanozip seems to have highest compression together with FreeArc. But it is not in final version yet. There is how good compression Nanozip achieves. It has very high compression and it does not takes too much time, check the Summary of the multiple file compression benchmark tests, but FreeArc is faster.
So I had this idea for an FTL drive that would work by creating a rift (a black hole before it tugs on space enough to become unstable and deadly) via an unbelievably strong magnetic field. I know that atoms are mostly empty space anyway, and they can be compressed to smaller sizes with a big enough applied force. But could a magnetic field actually produce a force capable of squishing a matter (probably plasma) down to the point where it would become a black hole?
Messy Stone is one of the most common blocks in almost any Bloxd world. It can be obtained by mining any stone or messy stone block. It can be compressed in the Artisan bench into darker and different blocks. There are Four variants of the Compressed Messy Stone. All Compressed Messy variants stone can be uncrafted into messy stone.

This study investigated the perceptual adjustments that occur when listeners recognize highly compressed speech. In Experiment 1, adjustment was examined as a function of the amount of exposure to compressed speech by use of 2 different speakers and compression rates. The results demonstrated that adjustment takes place over a number of sentences, depending on the compression rate. Lower compression rates required less experience before full adjustment occurred. In Experiment 2, the impact of an abrupt change in talker characteristics was investigated; in Experiment 3, the impact of an abrupt change in compression rate was studied. The results of these 2 experiments indicated that sudden changes in talker characteristics or compression rate had little impact on the adjustment process. The findings are discussed with respect to the level of speech processing at which such adjustment might occur.
I am having difficulties formatting the reference style in a template. I have added \PassOptionsToPackagesquare,comma,numbers,sort&compress,supernatbib to force compressed reference style to my document, however it is not giving me the desired result. Rather than formatting the references as [1-5] it is formatting them as [1,2,3,4,5]. I have attached a screenshot for reference. Any ideas on how to fix this? Thanks
Assuming you want numbers, which is also the default with the elsarticle document class, the easiest fix I can think of is to place the option sort&compress among the arguments of the \documentclass directive, i.e., to write
After messing around for a while, I found a solution that works in my case. Firstly I changed \usepackage[journal]elsarticle to \usepackage[journal,nonatbib]elsarticle to disable natbib being used by the class template. The line \usepackage[square,comma,numbers,sort&compress]natbib now works as intended. So apparently something in the template class was preventing natbib from taking in optional arguments. The final code is shown below for clarity.
