When I need to build a website, I typically use Hugo to generate the .html from .md. However, one thing is a bit inconvenient: deployment. If not done right, you have to do that manually (edit -> hugo -> rsync). Alternatively, and much better, you can use the Hugo-Gitlab|Hub-Netlify-toolchain I described earlier. These day, I needed a website for a new research project of mine and didn't want to ship the site with Netlify. Read more

I like to host (most of) the web services I use for my daily routine at home. Recently, I started shipping services using Docker containers. To make these services available via a public IP address and to conveniently enable HTTPS, I decided to use nginx as a reverse proxy. So the dockerized service becomes available via something like https://mydomain.dyndnsservice.xy/servicename. At least this was the plan. Unfortunately, I ran into the always same problem when I tried to coax a dockerized service to live happily in a “sub-folder” of my dynamic DNS domain. Read more

Since a good while I use the static website generator Hugo for my Blog (which (by the way) is back online since a few days (minus the photos) after I got rid of my vServer last month). As I do not have this vServer anymore, I neither have a repository that keeps track of my website's source code, nor a machine that will automatically build the website's html whenever I change something, nor a public web server to serve the website's html.

… a quick test of the Guetzli JPEG encoder published some weeks ago by Google. To my big surprise, you cannot encode TIFF or another lossless image format into JPEG. You need to export your RAW camera file first to JPEG @ 100% quality. Then you encode that file with Guetzli. Seems a tad odd to me, as you have a lossless compression two times. The speed of Guetzli is furthermore quite disappointing. Read more

I use the static website generator Hugo for this homepage. However I find that Hugo's capabilities are somehow restrained if you post a lot of photographs like I do. So far my approach has been to automatically generate markdown that includes the photos I want to show in a post chronologically. Furthermore I enforce that only the first photo is shown on the homepage with the ` Read more

Since a couple of months I deliver all my websites by HTTPS only. Certificates are issued by Let’s Encrypt and I use Certbot as a certification client (hope that is the correct word). This works quite well, actually. However, the certificates from Let's Encrypt have one drawback: they expire after 90 days. Hence, you need to renew the certificate now and then. The description from the Certbot page does not work for me as the renew verb of the certbot command would create one certificate (with many common names) for all pages served by the server.

Yesterday I reinstalled my virtual server and also created a new configuration for the Apache web server that fixed some issues of the old one. I also wanted to know how well the Apache is configured regarding the security of TLS. Some days earlier, I stumbled upon SSL Labs, a site offering some automatic checks regarding certificate, server configuration and the used server software itself. Seems the server is quite fine.
