Notifications for failed cron jobs

Cron jobs are a vital part of every sysadmins setup. Backups, log rotation, certificate renewal and whatnot. I've mostly just relied on them working as they should until now, but with my recent Huginn + Matrix obsession I figured I should have some sort of notifications. Crontab supports sending emails for your jobs, all you have to do is add at the top. It defaults (on most distros) to sendmail, which I discovered was kind of a pain to set up. Instead I found t

Nginx default server with https

My two favourite services

So I do a lot of self-hosting these days. I've always been keen on trying out new stuff that turns up but most of the services I just set up, keep for a couple of weeks and never use.

Nginx, Ghost and https

Mine now looks like this: server { listen 443 ssl; ssl_certificate /etc/letsencrypt/live/; ssl_certificate_key /etc/letsencrypt/live/; server_name www.jonnev

Ghost and production

There are 2 things you need to do to get ghost to run in production mode with docker: Add the NODE_ENV docker run -d --name ghost -v /path/to/blog:/var/lib/ghost -e NODE_ENV=production -p 2368:2368 ghost This is for ghost v0.11.x. For v1.x.x have a look at this post []! Note: If you're having trouble with the permissions on files in the volume, for example when trying to pull/add a theme, add this to the command above: -u $(id -u $USER):$(id -g

Blog up and running

So I figured I wanted to have a blog and in the process redo my homepage. A friend recommended Ghost and when trying out their hosted Pro version I thought it looked great! This is for ghost v0.11.x. For v1.x.x have a look at this post []! I wanted a clean and simple theme and when looking through the Ghost marketplace I found Steam []. I had some experience with Handlebars already and I quickly glanced through the
