- | Sometimes I wish I could slap people awake. It is right in front of their eyes and they do not see. When it is in the press, it is usually 180 degrees of what you are being sold. In other words a lie. I am looking for a new place to live, and when the ad says spacious, I always look at the square metering of the place, because it never is. When they say it has a beautiful view of the mountain, it means when you stand on your tippy-toes to see it over the large freeway taking up 70% of the view. When you do a cloud certification like Azure AZ-900, almost half of the time you are being told how much “cheaper” the “cloud” is. (Spoiler, it’s not) Then things in your face, like the slogan, “There is no cloud, it is just someone else’s computer” meaning “a large *evil corporation’s computer”. Now I know there are some honest cloud providers out there, don’t shoot yet. The thing is everyone wants to own what you have, by some sly means. Handing your data to a cloud provider, they will make doubly sure they have some legal way to steal your data. They will use it to train their “AI” (no such thing, just a way to take what you have and make it theirs) without even telling you. The EU put all these laws into place like the GDPR, but it is about as effective as putting toilet paper on a landmine to absorb the blast. There are already more than 50 ways to bypass every aspect of the GDPR, for instance. Why, you may ask? Simple answer is greed. Just like the “startup” idiocracy. The goal of a “startup” is to sell it to a big corporation for a lot of money, instead of working to make it your business and running with it. It is easy to rag on open source, but at least they are trying. | ||

- | Q: I have Ubuntu in Ubuntu. My host is Xubuntu and my Virtualbox is Ubuntu Gnome. I have shared the clipboard and folders, so I could move files to Gnome and when I look again, the Gnome VM is locked and I have to unlock it. It happens so frequently, that I have changed my password to ‘a’, just for this, it is so annoying. Is there anything I can do in the Gnome VM? | + | Parfois, je voudrais pouvoir gifler les gens pour les réveiller. C’est devant leurs yeux et ils ne voient rien. Quand ça paraît dans la presse, c’est habituellement à 180 degrés de ce qu’on vous vend. Autrement dit, un mensonge.

- | Q: I was configuring server 20.04 for games, when adding the IP address with the port it was established correctly, but I could not enter the game, I was looking at the server, I opened the firewall, I gave it sudo reboot, it froze, I updated and now it no longer works for me. | + | Q : J’ai Ubuntu sur Ubuntu. L’hôte est Xubuntu et j’ai Ubuntu Gnome dans ma Virtualbox. Le presse-papiers et les dossiers sont partagés pour que je puisse mettre des fichiers dans Gnome et quand je regarde à nouveau, la VM Gnome est verrouillée et je dois la déverrouiller. Cela se passe si fréquemment que j’ai changé mon mot de passe à « a », juste pour ça, cela m’agace tant. Y a-t-il quelque chose que je peux faire dans la VM Gnome ? |
+ | |||
+ | R : Demandez-vous comment garder votre session active ou ouverte ? Si c’est le cas, envisagez l’installation de caffeine et de l’indicateur caffeine dans la VM et activez-les avant de faire quoi que ce soit. Si vous dites que vos séances de copie s’arrêtent jusqu’à ce que vous vous connectiez à nouveau, il se peut que cela aide aussi. | ||

Les deux ont une carte mère MSI, une RAM Apacer et des disques verts WD. Elles se branchent sur un interrupteur D-link. Il n’y a pas de périphériques qui pourrait causer une baisse d’alimentation. Les écrans sont toujours VGA, pas HDMI. Je n’arrive pas à trouver ce qui cloche. | ||

A: You “opened” the firewall, do you mean disabled it? If you did not, that would be the reason you can no longer access the server. We did a short piece on Firewalls in CnC in the magazine, please give it a once-over. | A: You “opened” the firewall, do you mean disabled it?

Did you use a different version of Python before? It could also just be that that specific package was dropped in Ubuntu 24.04, in which case you need to find out what replaced it.

My machine keeps doing a journalctl when I start up, but I don’t know how to interpret this table? < | + | Q : Bon. Je me suis débarrassé du panneau Ubuntu et j’ai installé le dock Docky qui est nettement plus logique. Je ne comprends qu’une chose : comment avoir le truc de la grille de neuf boutons ? Ou comment le faire fonctionner sans le panneau Ubuntu, s’il vous plaît ? |

+ | Q : J’ai Xubuntu 22.04 sur mon portable Dell. La résolution de son écran est réglée à 3840 x 2160 sans mise à l’échelle. J’ai installé le thème du curseur de souris, DJ-FOX-C qui a l’air époustouflant. À côté du thème, il y a les boutons de la taille du curseur. Sur Xubuntu 20.04, je l’ai réglée de nombreuses fois à environ 50 pixels. Cependant, rien ne se passe dans Xubuntu 22.04. Le curseur reste à la même taille. | ||
+ | |||
+ | R : J’ai recherché les curseurs sur gnome-look.org et il y a un readme dans l’archive tar qui dit que la taille du curseur est de 36 pixels. « Size : ===== 36x36 ». Tous les curseurs ne sont pas faits avec des fichiers SVG et certains sont des PNG à la base. Vous pouvez faire une mise à l’échelle de SVG sans perdre la qualité. Cela dit aussi qu’il a un magasin ; ainsi, je soupçonne que si vous voulez un curseur dont vous pouvez changer la taille, vous pouvez l’acheter. | ||

Q: Man I hate man pages, most of the time they mean nothing if you don’t know what a command does.

+ | |||
+ | R : Je ne m’inquiéterais pas trop au sujet des autres valeurs. Ce que vous recherchez est la « RAW_VALUE » (valeur brute) des erreurs non corrigibles. Si elle est autre chose que 0, sauvegardez vos données tout de suite et cherchez un nouveau disque. | ||
+ | |||

+ | Q : Mec, je déteste les pages man, car la plupart du temps elles ne veulent rien dire si vous ne savez pas ce que fait une commande. J’ai cherché lsattr et tout ce qu’il dit est : « list file attributes on a Linux second extended file system ». À peu près aussi utile qu’un coq sur une selle. Comment un idiot comme moi peut-il apprendre quelque chose de ça ? | ||
+ | |||

I’m not sure what to do here. | ||
+ | A: It has nothing to do with your OS. You probably put one laptop on top of the other. The magnets in the slim laptops are strong enough to affect another laptop, as they are so thin. If you did not know, there are magnets in the base that move when another magnet is near, completing a circuit. The circuit then signals the lid closed and the laptop goes to sleep. (the method differs, but the effect is the same)** | ||
