I have been following Apple machine learning research for a while now and I have been stunned by their Keyframer demo application. I have been trying to replicate the Saturn SVG used in the demo and I think I have come up with a pretty good approximation.
In this article, I will explain why Python Virtual Environments are so cool when you know how to use them properly. I will also show you how to use them the right way.
Today I have upgraded my Fedora server from version 33 to 38 but all did not go as planned.
Today I was confronted with a quite annoying problem. I have a server with a 1Gbps network card connected to a 1Gbps switch. I was trying to backup my data as usual but the transfer was slower than usual. Using ethtool I saw that the link speed was only 100Mbps !
This article describes how to use a SSH CA to authenticate to SSH servers. This is particularly useful when you have a lot of servers to manage and you want to avoid the hassle of managing a lot of SSH keys.
The basic idea is to have a CA (Certificate Authority) that will sign the public keys of the users. Then, the users will be able to authenticate to the servers using their signed public key. This way, you don't have to manage the public keys of the users on the servers, you only have to manage the public keys of the CA. You can also limit the validity of the signed public keys to a certain amount of time or to a certain set of servers and users.
I have a lot of media to watch and I don't want to spend time searching for it, downloading it, renaming it, moving it, etc. I want to be able to request a movie or a TV show and watch it in less than 5 minutes. I also want to be able to watch it on any device, anywhere, anytime.
Now that I have generated by own custom certification chain in the previous article "x509 certificat managment" I need to install the Certificate Authority (CA) on my iPhone.
Assuming you are using the GitLab Terraform state feature in your self managed instance and you are using the embded backup utility provided by GitLab.
The Terraform state files are encrypted before they are stored. This means that you cannot retreiv the content at rest. For this purpose, GitLab use application secrets (and derive new secrets from thoses keys when needed) to encrypt sensitive content.
You want to retreiv the content of a state file from a GitLab backup. Like explained in this issue, it's not possible to easily retreiv a decrypted content is the instance is offline.
Any developper use or will use Git at a point in is career. Most of the time they will have to work with other people on the same Git repository. To avoid it to be branch and commit battlefield here is a simple guide on how to contribute properly on a Git repository.
Using OpenSource software written by unkown people sometimes can be a little scary. Even more when I deploy them I a production environment in my company. On my case, I have created a brand new Kubernetes cluster to host some private services on my local network and I wanted to be sure that they don't do anything malicious on my network.
