Docker - How to cleanup (unused) resources

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

delete volumes

// see: https://github.com/chadoe/docker-cleanup-volumes

$ docker volume rm $(docker volume ls -qf dangling=true)

$ docker volume ls -qf dangling=true | xargs -r docker volume rm

Cordova CI with Jenkins for iOS apps

Inspired by CI server on Mac OS for iOS using GitLab and Fastlane by @v_shevchyk we decided to write down our approach. This will be extended and improved over time.

So you want to deploy your Cordova app, but you hate opening xcode manually to archive and export and sign and cry? Try this. By this we mean we try to explain how to create the following CI (Jenkins) setup:

Build Cordova app
Create & sign your ipa file
Upload to HockeyApp (for Enterprise distribution)

With heightening concern regarding the state of internet privacy (fuelled in part by the passing of the Investigatory Powers Act in the UK), I have set up a VPN server on the virtual server I have hosted with Mythic Beasts. This uses strongSwan and certificate-based IKEv2 authentication.

Assumptions:

Debian Jessie server already set up and accessible via debian.example.com, a public IPv4 of 203.0.113.1 and a public IPv6 of 2001:db8::1
Client username of me
Clients are running the latest versions of macOS and iOS (Sierra and 10 respectively at the time of writing)
No need to support any other operating systems (although the setup is easily translated)

For automated deployment of a similar setup, albeit Ubuntu-based and using ansible for deployment, I recommend you take a look at Algo VPN. I used that project as a basis for my configuration.

strongSwan setup for Road Warriors on macOS 10.12, iOS 10 and Windows 10

This setup is for remote users to connect into an office/home LAN using a VPN (ipsec). This is based on (but not the same as) the strongSwan documentation and this guide: https://raymii.org/s/tutorials/IPSEC_vpn_with_Ubuntu_16.04.html

I used strongSwan 5.5.1.

apt-get install -y strongswan strongswan-pki

A Beginner's Hip Hop Playlist

Edit: After some constructive feedback on hacker news, I think that it's worth mentioning that this playlist is very skewed towards recent material, although I've included some essentials from the past.

I think that hip hop is one of the most, if not the most, misunderstood genres of music. In this playlist, rather than focusing on one artist or one type of hip hop, I tried to give examples of a bunch of different artists with songs ranging from the early 90's all the way up until 2017. The songs are in no particular order and the sounds cover a very broad spectrum. Some of them are pretty damn explicit, so I wouldn't necessarily throw this playlist on if there are kids around. I provided the lyrics to each song, the sub-genre that I'd put the artist in (very rough), and a brief description. This playlist is not by any means meant to be comprehensive and in many cases doesn't necessarily represent the artist's "best" song, but instead aims at exposing you to some of my fa
