UPDATE: i changed the source of the generator - if you want to see the updated source, please head over to the Github repo

Because I needed a quick (and reasonable secure) way to generate IOTA wallet seeds, I wrote a tool in Go.

this is the source code - so you can compile it yourself. you can also download it here (signature - my keybase profile).

Feel free to leave any feedback :)

Today I needed a postgres database for development that persisted its data when recreating the container. That’s not docker’s default behaviour, but docker volumes to the rescue!

This is the command to run a postgres container that persist it’s data in /var/yourpgdata:

docker run \
   --name pgresql \
   -d \
   -p 5432:5432 \
   -e POSTGRES_USER=yourpguser \
   -e POSTGRES_PASSWORD=yourpgpass \
   -e POSTGRES_DB=yourpgdb \
   -v /var/yourpgdata:/var/lib/postgresql/data

Fine… but what does this mean? Let me explain:

Today i opened my Calendar app on OS X and all my coworkers shared calendars had vanished… And there’s no option to re-enable them from within the app itself. After a short investigation I found this link:

https://calendar.google.com/calendar/syncselect

Just go there and tick all calendars you want to sync.

Today I had the case that I wanted to rename a subfolder in a git-project at work. “Easy” I thought. Just rename the file in finder, stage all un-staged changes in SourceTree, commit and push.

But… the only thing that happened was that SourceTree complained about not being able to find files in the old foldername. So I googled a bit and found a solution.

How to really do it

Just use git mv on the shell! The syntax is git mv {source} {dest}
