Japan’s National Theatre has risen to the occasion after the cancellation of Yoshitsune Senbon Zakura (Yoshitsune and the Thousand Cherry Trees), which was originally scheduled to open for audiences in Tokyo on March 3 of this year. Instead, the performance, sans audience, will be posted to the theatre’s online YouTube channel.

From author's notes:

Let’s get this straight: The effort to host Google web fonts on your own server is immense! First of all you need to download all .eot, .woff, .woff2, .ttf and .svg files, then copy them onto your server and finally paste a CSS snippet.

Sounds easy? Well it could be, if Google would actually provide any direct links to download these files and a customized CSS for self-hosting them. To fix this problem without using font generation services like Font Squirrel, I decided to publish a little service called google-webfonts-helper.

This site is the home- and demopage of the SAE, an Amiga emulator in pure HTML5 and JavaScript.

This is a site you use to test clients – mobile apps, browsers, and many other applications that use HTTP applications and TLS – the Transport Layer Security protocol. We have designed a lot of tests that checks if your browser or client application really checks the identity of the server it’s trying to connect to. It is important that developers understand how TLS works and how site verification works.
