Installing python packages from git via pip
It may happen that you need to install a python project with pip from git(hub). That’s pretty easy:
…Copy your private GPG key to a new machine
It’s really simple to copy your private GPG keys to another machine of yours. Let’s do public key first: $ gpg --export --armor KEY | ssh me@my-other-machine 'gpg --import' gpg: keyring `/home/me/.gnupg/secring.gpg' created gpg: keyring `/home/me/.gnupg/pubring.gpg' created gpg: /home/me/.gnupg/trustdb.gpg: trustdb created gpg: key 4937B925: public key "KEY" imported gpg: Total number processed: 1 gpg: imported: 1 (RSA: 1) It worked! Now the private: $ gpg --export-secret-key --armor KEY | ssh me@my-other-machine 'gpg --import --allow-secret-key-import' gpg: key 4937B925: secret key imported gpg: key 4937B925: "KEY" not changed gpg: Total number processed: 1 gpg: unchanged: 1 gpg: secret keys read: 1 gpg: secret keys imported: 1 (--armor is optional, it’s just for sake of checking the output first before piping it to ssh)…
Build docker engine on Fedora
It’s not that hard, here are a couple pain points:
- make sure that
GOPATHis right — you want to compile against your checked out docker, not master docker
How hard is it to get a digest of a docker image's manifest?
Update (October 13th): The encoding mismatch is made on purpose as described in this issue. The current work is present in this repo.
So I needed to get a digest of a manifest. Manifest is a text file in JSON format which contains metadata for a docker image. Manifest is part of v2 docker registry API.
We want to have this functionality (f(manifest) → digest) in pulp so I needed to do that in python. I guess it would pretty easy to do in Go because I would be able to use code from distribution directly.
hugo + netlify = ❤

Running chromium in docker container
I’ve just managed to dockerize chromium. The package itself is taken from spot’s copr repo. Jessie Frazelle’s blog post helped me a lot!
It looks like this:
…Fuzzy text search with trigrams in postgresql
Using postgres for fuzzy searches.
We’ll try to match arbitrary beer names to ones in our DB. Let’s create table first:
…Compiling kernel on gentoo
I’ve just updated to kernel 3.17. I compiled the kernel, installed it, generated initramfs, updated grub.cfg and rebooted my PC. I was unpleasantly surprised by:
