First post Sept. 12, 2017, Jochen A few weeks ago, I lost my old homepage. The motherboard of the server broke and my provider said that it was so old that they couldn't find a replacemen...
Usually I use nginx for static files, ssl termination and as a reverse proxy before my application servers. The django cookiecutter template came with a new webserver named caddy. It's written in go and https per default. Usually you have to fiddle around with certificates and a more or less complicated nginx config, but with caddy it was surprisingly easy. The certificate came from letsencrypt and it got installed automatically. After that my site got an A on the ssllabs ssl test page without any further tweaking. Caddy might be a bit slower than nginx, but it's probably fast enough for most people and solves an annoying problem. This is really cool.

Implementing pagination was also quite easy. Since I'm using class based views, I only had to add the attribute paginated_by = 5 to my view class and this snippet to my blogpost_list.html template:

,Jochen Today I switched from serving media files directly from s3 to cloudfront. The main reason is that s3 only supports http/1.1 while cloudfront also does http/2 which is much faster because images etc. could be downloaded in parallel.

I liked the idea, but wondered whether a simple kernel density plot would have the same effect. And if not, maybe how difficult it will be to adapt the approach to python. So I created this little jupyter notebook:
function resizeIframe(obj) {
obj.style.height = obj.contentWindow.document.body.scrollHeight + 'px';
}
