Du droit des auteurs morts
La récente affaire Hemmingway de Gallimard publie.net est l'occasion de réfléchir au système actuel de droit d'auteur.
Le droit d'auteur définit des droit “patrimoniaux” sur les œuvres de l'esprit, c'est à dire un monopole de l'auteur et de ses ayant-droits sur l'exploitation des œuvres. En clair, seul l'auteur d'une œuvre et ceux qu'il autorise sont autorisés à l'exploiter de quelque façon que ce soit. Ce monopole s'étend de la création de l'œuvre jusqu'à soixante-dix ans après la mort de l'auteur, après quoi l'œuvre s'élève enfin dans le domaine public et peut alors être utilisée librement.
Opportunistic SSH agent
Classified in : Homepage, Debian, Command line, Lazyweb
To use an SSH agent, one usually has to:
- launch the agent;
- add his key to it.
The first step can be automated in the desktop or shell startup script (this is a typical use case for login shell-only startup scripts, by the way), but the second one cannot if your private key is protected by a passphrase.
OpenSSH tip: connection sharing
Classified in : Homepage, Debian, Command line, To remember
The last versions of OpenSSH brought an interesting feature: sharing multiple sessions over a single connection. When enabled, this is how it works:
- The first time you open an SSH connection to a server (including anything that works on top of SSH, like SCP, SFTP, rsync or Git), it opens a network connection as usual. It also opens a local Unix socket and listens to it for later use.
- The next times you open an SSH connection to that server while the first one is still open, instead of opening a new network connection, it connects to that local Unix socket and lets the first SSH client carry its new session.
Debian with AMD graphic cards
If you install Debian on a computer with an AMD graphic card (an integrated Radeon HD 6310 in my case), you will only get garbage on your screen. Even without X.Org.
This is because these graphic card require a non-free firmware to work, even in 2D with free drivers. So, boot with the kernel option radeon.modeset=0 to get a working console, then install the non-free package linux-firmware-nonfree.
After that, do not forget to complain to AMD, because that really sucks hard. At the beginning there were microwave network cards unusable without non-free firmware, then wired network cards, and they are even invading graphic cards!
Debian buttons for Firefox/Iceweasel
As a Debian administrator, power user or contributor, one often goes to look for information about a package, a bug, a developer or a message from the mailing lists. If you are in this case, you may be interested in the Firefox/Iceweasel extension “Debian buttons”, written by Damyan Ivanov and packaged by myself.
