Use Let’s Encrypt to add an SSL certificate to your Dreamhost-hosted site

Update 2/2016: You don’t need to follow any of the instructions in this post any more! You can just enable a Let’s Encrypt certificate in the Dreamhost panel! But if you want to generate your own Let’s Encrypt certificate locally and add it to your site, keep reading, original post follows …

EFF’s Let’s Encrypt initiative just made getting a free, CA-signed server certificate easier than it’s ever been before. Running a single command generates everything you need, obtains the public cert and even installs it into your webserver of choice. So let’s encrypt, and move the web closer to HTTPS everywhere!

Here’s a quick tutorial for using Let’s Encrypt with Dreamhost’s shared hosting. It’s not quite automatic, since you’ll have to copy-paste 3 things into boxes via the Dreamhost web panel, but it’s a lot simpler than the alternatives. As someone who’s done this the old way countless times, Let’s Encrypt was shockingly easy! more …

Add Brotli compression support to Apache for static assets and pages

The Apache web server doesn’t yet support stream compression using Brotli, but it’s easy to add support for static pages and assets such as CSS and Javascript files that you precompress. Browser support for Brotli is coming in Firefox 44 and in Chrome, and it provides about 15% savings versus precompressing with gzip/deflate. more …

Innovation in Lossless Compression: Apple’s LZFSE, Google’s Brotli and Yann Collet’s Zstandard

With Google’s recent open-sourcing of Brotli following on the heels of Apple’s announcement of LZFSE, it’s an exciting time in the lossless compression world, as new compression schemes tuned for specific use cases now appear to offer substantial enough benefits to challenge the venerable ZIP/Deflate as the Internet’s transport compression algorithm of choice.

Of course, Deflate and its most widespread implementation, zlib, aren’t dead yet, not by a long shot. But what these new LZ77 algorithms offer is significant enough performance gains to justify widespread implementation, and adoption by the W3C. And they have the backing of companies such as Google and Apple, which means they’ll ship on tens of millions of devices and browser installs. more …

Outernet’s solar-powered content downloader, Lantern

In the age of the Internet of Things, it is interesting to see a non-Internet device that uses Web technologies in a new way. Outernet is a project started earlier this year by the nonprofit Media Development Investment Fund that buys bandwidth on communications satellites to do one-way broadcast of news, education and other critical content worldwide.

Already available to anyone willing to do a little work with off-the-shelf hardware like Raspbery Pi, Outernet now have an integrated, solar-powered receiver called Lantern that doubles as a charger, theoretically enabling offline, anonymous read-only access to Web content anywhere in the world. more …
