The slack part make it loose 1mm before it actually move. This could explain the square shape. Because the labists x1 mini does not provide adjustment screws, I had to disassemble it, stretch the belt and assemble it again.

Here, I’m mixing the method and the tool. I don’t like it (don’t confuse the tool and the method), but at least I am aware of it. So this makes sense if schedule means “I don’t want to see this before that date” and deadline means “whatever happens, this will be done before that date”. If you use other meanings, the following is irrelevant to you. There are 3 repeaters .+, + and ++. Those repeater are great for simple active timestamps and fulfil a lot of my use case, but don’t work well when you have to orchestrate the planning that has a scheduling and a deadline that are correlated. Those are the use case I have and the reasons why I encourage not to use + or ++ and prefer edna when dealing with both schedule and deadline. I still use + for cases where edna won’t help. /blog/posts/new_battery_cap_for_amelle_la_tractopelle/ Fri, 06 Jan 2023 09:51:00 +0100 konubinixweb@gmail.com (Samuel Loury) /blog/posts/new_battery_cap_for_amelle_la_tractopelle/ https://cults3d.com/fr/mod%C3%A8le-3d/jeu/vtech-go-go-tut-tut-bolide-couvre-batterie /blog/posts/how_to_make_mime_recognize_mail_files/ Fri, 02 Dec 2022 15:18:00 +0100 konubinixweb@gmail.com (Samuel Loury) /blog/posts/how_to_make_mime_recognize_mail_files/ how to make mime recognize mail files I store important mails inside ipfs, see my ideal file system. Unfortunately, most of those I save are not recognized when they don’t have an extension. My debian system already has a bit of mime magic to find out rfc822 files. sed -n '/^\[50:message\/rfc822\]/,/^\[/ p' /usr/share/mime/magic [50:message/rfc822] >0=#! rnews >0= Forward to >0=From: >0= N#! rnews >0=Pipe to >0= Received: >0=Relay-Version: >0=Return-Path: >0=Return-path: >0= Subject: [50:model/iges] Somehow, it expects the metadata to be prefixed by a tabulation character, whereas my mails don’t have.

Therefore, I don’t need the part of exporting the ssh key since it is already in the keyring. I can simply find the keygrip in ~/.gnupg/sshcontrol and insert this key in my primary keyring only for authentication purpose. Well, the following commands will show I was wrong. $ gpg --expert --edit-key mykey addkey 13 thekeygrip a s e q save The key is imported, but it has the ssh-passphrase in it, so I cannot make it use the gpg secret key one. Also, trying to directly import the ssh key into my keyring makes the ssh client not able to use the key. I don’t know why. I eventually used a temporary keyring and imported the ssh key, like indicated in the article and it worked fine. In the future, I might want to remember to follow the advise of https://opensource.com/article/19/4/gpg-subkeys-ssh-manage to deal with the ssh key fingerprint. /blog/posts/get_rid_of_some_file_from_git_history/ Wed, 18 Aug 2021 13:29:00 +0200 konubinixweb@gmail.com (Samuel Loury) /blog/posts/get_rid_of_some_file_from_git_history/ Imagine you just realized you added a long time ago in your git repository some files that don’t belong here, like ./target.
