You can scale a SQLite database to multiple GByte in size and many concurrent readers by applying the below optimizations.

Run these every time you connect to the db

(some are applied permanently, but others are reset on new connection)

pragma journal_mode = WAL;

Instead of writing directly to the db file, write to a write-ahead-log instead and regularily commit the changes. Allows multiple concurrent readers, and can significantly improve performance.

I am not a fan of Xcode.  Here are ~160~ 200 problems, the first hundred or so issues were filed mostly in 
July and August 2016 in a fit of rage.  Mostly on weekends working (slowly) on side-projects.  I have also
taken days of my employer's time filing others of these - so the company was not getting value for my time.

I believe a paid intern could have found many of these - just start a screen recorder, and when you see something,
stop and cut a quick movie.  Many have been around for several major versions.
I'm volunteering chunks of my life (15-30 minutes per) to one of the most valuable companies in the world, which seems
kind of messed up. Things get worse the more complex the project and the longer Xcode been's running.

Bootstrap the Synology DS215j with optware-ng

I tried the instructions described in the Blogpost Bootstrap DS215j to install optware for ds215j but was unsatisfied with the long outdated packages it provided. Luckily, there now is optware-ng which is a fork of optware and provides recent packages.

This is how I managed to install optware-ng on my Synology ds215j inspired by the instructions in the Gist Boostrap the Synology DS215j with optware, ipkg, and sudo:

Download & Install ipkg in a persistent manner
