Caddy vs. nginx
Caddy vs. nginx
, JochenUsually 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.
Responsive images
Responsive images Sept. 20, 2017, Jochen Images are a lot harder than I expected. Naively I assumed, I could just add an img-tag with the original image and bootstrap woul...

Added pagination
Added pagination
, JochenImplementing 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:
{% verbatim %}<nav aria-label="pagination"> <ul class="pagination"> {% if page_obj.has_previous %} <li class="page-item"><a class="page-link" href="?page={{ page_obj.previous_page_number }}">previous</a><li> {% endif %} {% if page_obj.has_next %} <li class="page-item"><a class="page-link" href="?page={{ page_obj.next_page_number }}">next</a></li> {% endif %} </ul> </nav>

Using a CDN
Using a CDN
, 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.Tartlets

Scatter plots with density quartiles with python
Scatter plots with density quartiles with python
, Jochen The other day I saw an interesting blog post about scatter plots with density quartiles using r.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'; }
