Nerd Fonts – Les meilleurs polices pour les développeurs
@Korben — 19 août 2021
Les polices de caractères, c’est cool, mais ce n’est pas forcement adapté à tous nos usages de nerds… Parfois, notre police (ou font) préférée manque de certains symboles et ça fait des carrés chelous dans nos terminaux ou nos IDE.
Heureusement, il existe un super projet collaboratif qui s’appelle Nerd Fonts et qui vise à patcher les polices de caractères les plus appréciées des développeurs et autres informaticiens en y ajouter un grand nombre de glyphs (icones) en provenance de projets que vous connaissez tous :
Powerline Extra Symbols
Font Awesome
Font Awesome Extension
Material Design Icons
Weather Icons
Devicons
Octicons
Font Logos (Formerly Font Linux)
Pomicons
IEC Power Symbols
Seti-UI + Custom

The /bin/true Command and Copyright
by John Chambers
One of the fun examples among all the copyright fuss is the extreme example of copyright claims made by AT&T some time in the 1980s. It's the /bin/true program. This is a "dummy" library program whose main function is to make it easy to write infinite loops (while true do ...) in shells scripts. The "true" program does nothing; it merely exits with a zero exit status. This can be done with an empty file that's marked executable, and that's what it was in the earliest unix system libraries. Such an empty file will be interpreted as a shell script that does nothing, and since it does this successfully, the shell exits with a zero exit status. But AT&T's lawyers decided that this was worthy of copyright protection.
The earliest copyrighted version of /bin/true that I've found so far dates from 1984:
| # Copyright (c) 1984 AT&T | # All Rights Reserved | |
|---|---|---|
| # THIS IS UNPUBLISHED PROPRIETARY SOURCE CODE OF AT&T | ||
| # The copyright notice above does not evidence any | ||
| # actual or intended publication of such source code. | ||
| #ident "@(#)cmd/true.sh 50.1" |
That's the entire file. I've added the initial "| " so that you can see the exact contents. Note that it only contains blank lines and a comment (the #ident line identifying it as the "true" command). That's right; AT&T claimed copyright on three blank lines. So if you use blank lines in any of your files, you are in blatant violation of AT&T's copyright claim.
Lest you think that this is a fluke that was quickly corrected, here is the /bin/true program from AT&T's Sys/V libraries as of 1990:
| # Copyright (c) 1984, 1986, 1987, 1988, 1989 AT&T | # All Rights Reserved | |
|---|---|---|
| # THIS IS UNPUBLISHED PROPRIETARY SOURCE CODE OF AT&T | ||
| # The copyright notice above does not evidence any | ||
| # actual or intended publication of such source code. | ||
| #ident "@(#)true.sh 1.6 93/01/11 SMI" / SVr4.0 1.4 / |
Note that there is still nothing in this script except three blank lines and a copyright notice, plus the #ident line that now identifies it as version 1.6.
It might also be noted that, since I am "publishing" the entire contents of an AT&T program I am in blatant violation of AT&T's copyright claim. I've pointed this out publicly on numerous occations, in various technical forums, since the early 1980's. So far I haven't heard a word from any AT&T lawyers. Anyone have any idea why they are ignoring such a violation?
We might also note that linux systems avoid violating this copyright by replacing /bin/true with a compiled binary. This also runs a lot faster than the above shell script, since it avoids firing up a second unrelated program (/bin/sh) to do nothing. This is yet another reason that linux outperforms unix. And they were apparently forced into this efficiency improvement by AT&T's copyright claim. ;-)
Addendum:
AT&T isn't the only company to do such things. Here's the same program on a Solaris system in 1993:
| $ cat /usr/bin/true | #!/usr/bin/sh | # Copyright (c) 1984, 1986, 1987, 1988, 1989 AT&T | # All Rights Reserved |
|---|---|---|---|
| # THIS IS UNPUBLISHED PROPRIETARY SOURCE CODE OF AT&T | |||
| # The copyright notice above does not evidence any | |||
| # actual or intended publication of such source code. | |||
| #ident "@(#)true.sh 1.6 93/01/11 SMI" / SVr4.0 1.4 / |
Note that there is one less blank line here; it has been replaced by the #! line. But otherwise it is identical. Sun has merely passed on the copyright notice. I wonder if Sun has written permission from AT&T to use blank lines in their code? And I'm a bit disappointed that Sun didn't replace "AT&T" with "Sun Microsystems" throughout. Maybe their lawyers advised not to do this.
Meanwhile, the nice folks at GNU have handled this issue by reimplementing the "true" command in C. This program isn't just smaller and faster than the old shell script, which requires firing up a new shell process to successfully do nothing. They also added some important command-line options:
--help display this help and exit
--version output version information and exit
Presumably these options were added so they could claim that this wasn't just a stolen copy of the AT&T code; the GNU version actually contains code that does something. Those GNU folks do have a sense of humor. Here's the result of the --version option on a handy linux (knoppix) system in 2007. Note that it's up to version 5.94. Note also the claim that there is no warranty, which in this case presumably means that if the program actually does something, you can't sue them. And note that this version does something that's almost unknown in the software business: It includes an attribution giving the programmer's name.

The /bin/true (or /usr/bin/true) command is now nearly obsolete, because most extant shells now have a builtin "true" command. But it's still useful occasionally, for various silly reasons, and the attempts to copyright it are still a good source of absurdist humor. It's especially fun to note that GNU has reason to copyright their version. This prevents AT&T, Sun or SCO from taking the GNU code, claiming it as their own, and suing the linux crowd for infringement. Copyright © John Chambers, 1990, 1993, 2003, 2007, 2009 ;-)

Bon je grogne contre Mozilla, mais Mozilla, je t'aime !, parce que t'es l'un des seuls éditeurs de navigateur à faire une page comme ça: Comment empêcher Firefox d'établir automatiquement des connexions sans ma permission. Et ça, c'est très bien. (Il manque juste un paragraphe sur le préfetching DNS).

Réglage du cache
Par défaut, Firefox garde en cache les éléments des pages. Il utilise un cache mémoire et un cache disque (entrez about:cache dans la barre d'adresse). Si vous avez beaucoup de mémoire (>8 Go) il est possible de désactiver le cache disque et d'avoir un cache exclusivement en mémoire. En éliminant ainsi les I/O liées au disque, cela permet d'avoir un affichage des pages plus réactif (et cela économise aussi votre SSD).
Dans about:config, faire:
browser.cache.disk.enable = false : Couper le cache disque.
browser.cache.memory.capacity = 512000 : Augmenter le cache mémoire à 512 Mo.
browser.cache.memory.max_entry_size = 50000 : Augmenter la taille maximal des objets gardés en cache (50 Mo au lieu de 5 Mo par défaut).Personnellement, je couple également cela à un cache DNS local avec un TTL forcé (voir cette page).
Contrepartie: Quand vous fermez Firefox, le cache est vidé. Mais quand on a Firefox ouvert toute la journée, ce n'est pas un problème.
(Et si vous vous posez la question: Non on ne peut pas désactiver le cache disque de Chrome/Chromium: Il continuera à faires des I/O disque comme un gros goret. Conseil: Mettez votre répertoire cache de Chrome/Chromium en tmpfs pour régler le problème.)
Retirer l'avertissement sur les formulaires http
Depuis quelques versions, Firefox affiche un avertissement sur les formulaires de login qui ne sont pas en HTTPS. Même si je comprend la motivation, c'est carrément pénible sur un intranet ou pour des tests en local. Voici comment supprimer cet avertissement.
security.insecure_field_warning.contextual.enable = false
signon.autofillForms.http = true

Fr-OSS sous Windows sans installer quoi que ce soit
Il y a quelques jours je postais une note pour dire que c’était la galère pour écrire français sous Windows.
En fait, non, c’est possible et c’est aussi simple qu’installer un petit programme qui va modifier la disposition du clavier et en faire un clavier Fr-OSS (programme fourni par Microsoft, mais qui n’est pas installé par défaut malheureusement).
Sauf qu’installer un programme n’est pas toujours possible, en particulier dans un environnement où l’on ne peut pas installer tous les programmes que l’on souhaite (par exemple au travail).
Roland (un lecteur) me signale l’existence du programme Portable Keyboard Layout.
C’est un vieux truc (ça date de 2009), mais ça marche encore.
Il n’y a pas besoin d’installer quoi que ce soit, juste de pouvoir exécuter (pas besoin non plus des droits admin) un petit .exe qui va mettre une icône dans la zone de notification.
En ligne, j’ai trouvé les dispositions Colemak et Bépo, mais évidemment pas Fr-OSS.
Du coup je l’ai créé et la voici :
fr-oss.zip (sha1 : 57af9a18dd92cbc9b4faf2ca8f24e062fa170dbf)Il suffit de dézipper le fichier, de mettre ça où vous voulez et de lancer l’exécutable pkl.exe qu’il y a dedans (et si besoin ajouter ce .exe à la liste des programmes lancés au démarrage).
C’est tout. L’icône apparaît dans la zone de notification.
Un clic dessus et il se désactive, un nouveau clic dessus et il se réactive.
Pour ma modif, j’ai seulement modifié manuellement le fichier layout.ini et j’ai viré tout le reste. Je n’ai pas fait les images pour aider à afficher la disposition du clavier.
Avec ceci, au moins, vous pouvez taper des Æ, É, À, Ç, «», et ’. Comme sur un clavier Fr-OSS disponible sous Linux, sous le nom « français — alternative ».
La seule différence avec le Fr-OSS sous Linux, ce sont les touches mortes : dans cette version, bien qu’ayant respecté leur position, je l’ai considérablement étendu en reprenant la liste des touches mortes du Bépo (on peut donc taper à peu près n’importe quel diacritique de l’alphabet latin, et il y en a un paquet).
