Setting up Postgres on NAS

Network storages are really handy when it comes to a lot of disk space. Cheaper disk space available, RAID and after all it's a small server, 1GHz/256MB in my case. I wish I had NAS before.

I bought the one from Western Digital, MyCloud EX2Ultra to be specific, and one of the main reason for that is being able to work with a huge database. Consider Postgres, which runs on my Mac with 256GB, so any database larger than XX Gb is large enough to worry about. You can solve this problem with cloud, but what about 2TB database? 20TB?

My first attempt was about mount drive manually and create the database there:

mount -t smbfs smb://MyCloudEX2Ultra/Public/db db

Proposal for lightning talk at Reactive Conference.


Use case for react-native-macos

React Native for macOS (a.k.a React Native Desktop) started as an experiment a year ago, just out of curiousity and the active stage of development also took place during the previous Reactive conference right in the hotel room in Bratislava.

5 minutes talk about why you probably haven't heard about any real desktop application based on RN, and for what kind of applications it might be perfect fit.
