docker
I moved the blabbering behind the important stuff: how to get rid of the docker images/containers docker system prune # dangling containers docker system prune -a # dangling,stopped containers and all unused images docker rmi $(docker images -a -q) # all images docker rm $(docker ps -a -f status=exited -q)
If using CMake's file glob_recurse for catching source-file and you want this to also follow symbolic-links, just add the 'FOLLOW_SYMLINKS'-keyword: Like this: file( GLOB_RECURSE SOURCE_FILES FOLLOW_SYMLINKS src/*.cpp src/*.h ) Have look here: cmake file-docs And a bit related. In

rpi,cluster,nfs Since I'm still experimenting with kubernetes and docker and on the search for a good filesystem-backend, I can put the data on. I first used a simple nfs-server then had problems with postgres, then I tried cephfs, which worked but seemed to be an overkill

vim,linux One of the most annoying things is for me when (VIM(editor))[https://www.vim.org/] is switching to visualmode when you use the mouse-select. Especially this is the case on (armbian-systems)[https://www.armbian.com/]. I stumbled over a (github-comment)[https://gist.github.com/u0d7i/01f78999feff1e2a8361#gistcomment-3008129]
cmake
As I'm building my little Urho3D based game-server to run on rpi and alike systems I tend to compile the whole stuff on the device itself. (Yeah,...I should have a look in just cross-compiling...). I often struggled to finish compilation due to problems with angelscript and assimp
docker
I struggled for some time getting postgres to run on docker/k8s with /var/lib/postgresql/data mounted on an nfs-server. I reguallary ended up with chown: changing ownership of '/var/lib/postgresql/data/base/**/**': Operation not permitted. I'm no expert in nfs and its export-options
ceph
If you need to get rid of device mapper entries, e.g. because the disc-device you are using was formerly an ceph-OSD. sudo fdisk -l ...

docker
If you tried to login to docker hub using linux: docker login You might have trouble and getting a nasty problem: error getting credentials - err: exit status 1, out: `GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.secrets was not provided by any .service files` To
kubernetes
Atm I'm fiddling around with my raspberry pi,orange pi,odroid-Kubernetes,Docker,Ceph-cluster. Here some links: * Install k8s on arm/rpi * k8s: Expose pods externally via services (manual or metacontroller)
linux
Since I'm setting up my orange pi,rpi,odroid cluster for the n-th time I actually found a great tool the helps you do everything at the same time in different terminals. "Terminator"
ZeroMQ-based thrift "peer" that is server (multiple services) and client in one. Using one router for punshing out. See the github-repository for the source-code: https://github.com/dertom95/zeromq-thrift-p2p * What is it good for? Ever used thrift but wanted a way the server could push calls to the
git
If you want to include a submodule fully into your sourcetree (because you are forced to as in Unity3d) you can have some kind of workaround using a sparse-checkout (EDIT: with drawback...see bottom) Just do it like this: * create git-project (if not done yet): git init mkdir Project/Assets/
