rclone systemd service

Preparation

This service will use the same remote name you specified when using rclone config create. If you haven't done that yet, do so now.

Next, create the mountpoint for your remote. The service uses the location ~/mnt/<remote> by default.

mkdir ~/mnt/dropbox

Converting a Word Document to Markdown in One Move

Installing Pandoc

The Solution

Finding a Ruby memory leak using a time analysis

When developing a program in Ruby, you may sometimes encounter a memory leak. For a while now, Ruby has a facility to gather information about what objects are laying around: ObjectSpace.

There are several approaches one can take to debug a leak. This discusses a time-based approach, where a full memory dump is generated every, say, 5 minutes, during a time that the memory leak is showing up. Afterwards, one can look at all the objects, and find out which ones are staying around, causing the

dokku postgresql rsync nightly backup

This is a rough guide to automating a nightly 7-day rolling remote backup of your PostgreSQL database(s) for your dokku app(s). There is a slight difference if you are using an older version of Dokku.

This will save the comprssed output of pg_dump as well as the contents of the /home directory on your dokku machine (just in case).

You will need to create a shell script in /root and edit the cron file.
