Migrated Blog From Wordpress To Hugo

QNAP NAS: Create Backup of TimeMachine Directory

I was recently setting up remote backups for my QNAP NAS and came across a problem. QNAP NAS by default doesn’t seem to be able to create backups of the TMBackup directory it uses to store TimeMachine backups.

Scala Patterns To Avoid: Implicit Arguments With Default Values

There is a tendency for the Scala projects to prefer more explicit programming style. The biggest aspect of that is in my opinion the type system of the Scala language, programmers often start writing their functions by defining types of the arguments and type of the result, only to write the body of the function as last step. That’s also because we have the Scala compiler to help us.

Remote Work - 5 Years Later

This month it will be my 5 year anniversary as a remote worker. During that time I have been working for different companies, some were fully remote, some were partially remote. In some cases I have worked with teams with almost no time overlap (9 hours difference), in some cases all of us were in the same time zone. This post is an attempt to summarize my thoughts from the 5 year perspective, but also I’d like to share tips for both people who are remote members in their teams as well as for people who are working exclusively on-site while some of their peers are remote.
