Re-balancing Deflate Compression Levels
klauspost 0 31st January 2016 Go, Programming, WebAfter I have spent a lot of time optimizing the Go deflate compression, I found that a lot of my benchmarks were looking like this:

Creating a “Load Balancing Reverse Proxy” in 1 Work Week
klauspost 0 25th September 2015 Go, Programming, WebLast week I gave myself the challenge to create something in a week. Not a mockup, but a complete usable solution with documentation and enough tests to make it feel solid. I have been looking at DigitalOcean for some time, and while browsing their documentation I came across a sample script that would help you set…
Fast Linear Time Gzip/Zip Compression
klauspost 1 26th August 2015 Go, Programming, WebThis is the final chapter in our trilogy of exploring deflate performance. In this I will give a detailed description of how you can get close to constant time compression for gzip/zip and standard deflate running at approximately 150MB/s per core.
Gzip Performance for Go Webservers
klauspost 13 5th August 2015 Go, Programming, WebIn our previous performance test, we looked at high throughput compression, suited for log files, map-reduce data, etc. This post will deal with webserver performance, where we will investigate which gzip is best suited for a Go webserver. Update (18 Sept 2015): Level 1 compression has been updated to a faster version, so the difference…
Go gzip/deflate benchmarks
klauspost 5 31st July 2015 Go, Programming, WebAs a continuation of my release of a Optimized gzip/zip packages. I have done some informal benchmarks to get an impression of performance characteristics of the various libraries. I have compiled the results in a spreadsheet you can view yourself. Update (18 Sept 2015): Level 1 compression has been updated to a faster version, so the difference to…
Big Password Dictionary for Validation
klauspost 0 8th July 2015 Security, WebContinuing my previous posts [1][2] on checking passwords against dictionaries, I have completed a dictionary for the extremely paranoid. It is a compilation of the ‘Crackstation‘, ‘g0tmi1k‘ and ‘WPA-PSK WORDLIST 3 Final’ dictionaries. The passwords are all in lower-case, Unicode NFKD normalized, unique and sorted. I also dropped all passwords shorter than 8 characters and more…
Password Requirements Done Better
klauspost 0 30th June 2015 Programming, Security, UX, WebWe have all encountered them: Password Requirements. They are a well-intended attempt to make sure that your personal information stays hidden, and only you can access your websites. However, there are still many very annoying password requirements, and attempts at visualizing a “password strength” to help you choose a good password. However, I find that…
