+ | **We went to a bird sanctuary to take some photos. It was one of those with the wooden walkways that took you ever higher into the treetops so you could get closer to the birds – that would obviously go as high as they could. There were some large tropical parrots, etc, that were not skittish and would sit on branches about two meters away from you, and while these made lovely pictures, they were not the only birds there and we wanted pictures with more variety. So the hunt was on for elusive birds. Quickly we learned that using other people was easier. If you saw someone really putting effort into taking a picture, you went there to see what they saw and hopefully get a nice picture too. This worked well enough. We got quite a few pictures, but no real close-ups. When we reached the end of the path, there was a restaurant of sorts. Most people just headed for the gate in a hurry, meaning the place wasn’t busy and also not empty. We sat down and ordered milk shakes and fruit juice.** | ||

+ | **We finished our fruit juice and sat chatting for a while. By the time the milkshakes arrived, we were calm and relaxed and accepted that we got mostly hidden bird photos. Sitting back discussing all the beautiful birds, a cockatiel landed on the table. As a joke, I offered him some milkshake via the straw. He actually came forward and took it. He flew off and returned with a friend also wanting milkshake. I obliged, and somehow made new friends. They came to sit on my shoulders and I fed them milkshake drops. Other birds, seeing this, wanted in on the action, and soon I was covered in birds. Some German tourists stopped and wanted to know if I worked there. The spectacle not only got my girlfriend some nice photos, but lots of tourists too. We filled the rest of our SD cards with dozens of nice close-up shots. Moral of the story; if you have a problem, keep at it, sure, but some time or other, take a break, have a coffee, think about something else, the solution may come to you. ** | ||
+ | Après avoir fini le jus de fruit, nous sommes restés là à bavarder pendant quelque temps. Quand les laits frappés sont arrivés, nous étions calmés et détendus et avions accepté le fait que la plupart des photos étaient celles d’oiseaux cachés. Pendant que l’on discutait de tous les magnifiques oiseaux, une calopsitte élégante s’est posée sur la table. Pour plaisanter, je lui ai proposé de boire un peu de lait frappé avec la paille. Elle s’est approchée et a pris du lait frappé. Puis elle s’est envolée et est revenue avec un copain qui voulait du lait frappé aussi. Bien sûr, je lui en ai donné ; ainsi, je me suis fait de nouveaux amis. Ils sont venus s’asseoir sur mes épaules et je leur ai donné des gouttes de lait frappé. Ayant vu cela, d’autres oiseaux voulaient participer à la fête et j’étais bientôt couvert d’oiseaux. Des touristes allemands se sont arrêtés pour me demander si j’y travaillais. Ma copine a pris quelques jolies photos grâce au spectacle, qui a attiré beaucoup de touristes. Nous avons rempli le reste de nos cartes SD avec des dizaines de bons gros plans. Morale de l’histoire : | ||

- | A: Yes, developers sometimes forget normal people use the product. The secret is the 404, with an IP, meaning that the server is available, but the path or final destination of the URL is not found. This usually indicates that a URL has changed. I will bet it is a source that has been archived or moved. Just check it: by that I mean you can go to the URL in a browser, if it is not there, go a directory up and see. Rinse and repeat. | + | A: Yes, developers sometimes forget normal people use the product.

+ | |||
+ | R : Oui, parfois les développeurs oublient que des gens normaux utilisent leur produit. Le secret est le 404 avec une IP, ce qui signifie que le serveur est disponible, mais que le chemin ou la destination finale de l’URL n’est pas trouvé. Cela indique habituellement qu’une URL a changé. Je parie que c'est une source qui a été archivée ou déplacée. Il suffit de la vérifier, en allant à l’URL dans un navigateur et si elle n’y est pas, monter d’un répertoire et regarder. À Répéter si nécessaire. | ||

A: I don’t know the answer, but I can tell you how to see. Copy your hard drive image to another device and spin it up there. Simply click on the “ADD” button in virtualbox and select the vdi. On the Windows side, run a checkdisk, force it. Maybe do a full shut down by holding in shift before you do. | A: I don’t know the answer, but I can tell you how to see.

Q: So I am learning Ubuntu and I need to know how come some commands are the same if I use sudo or not? | Q: So I am learning Ubuntu and I need to know how come some commands are the same if I use sudo or not? | ||
- | A: Do you mean the output? OK, here goes, commands are static (the same always) but the permissions are not. The command ls lists the output of a folder, regardless of who you are. Sudo is ‘superuser do’ if you like, so running ls on a folder that you do not have permission to access as a user, will net you nothing, but if you run ls as sudo, you are now the superuser, and have access to all; that is it; it does not change the command, it simply changes your permissions. | + | A: Do you mean the output?

The problem is that when I try to install Ubuntu, it says the drive is unclean? I just cleaned up 100GB for Ubuntu, what is this about? |
A: The “clean” refers to a flag set on NTFS. To have that flag set, do a disk-check on Windows, let it complete, then hold shift and shut it down (see above). This actually shuts down Windows as opposed to some hybrid sleep thing. Now you should not have an issue installing Ubuntu. | A: The “clean” refers to a flag set on NTFS.

- | Q: When my Ubuntu 22.04 (tested this in 20.04 too) wakes up, my headphones (logitech USB) connected to my Dell dock (WD-15) are no longer the default sound in / output. So if I had my laptop playing a youtube video, and I closed the lid, the moment I opened it, the audio started coming through the laptop speakers instead of the headphones. This is especially annoying when I take a Skype call.

Le problème est que, quand j’essaie d’y installer Ubuntu, il dit que le disque est « unclean » (n’est pas propre). Je viens de nettoyer 100 Go pour Ubuntu ; de quoi s’agit-il ? |
+ | |||
+ | R : Le « clean » se réfère à un drapeau mis sur NTFS. Pour pouvoir régler ce drapeau, faites une vérification de disque sur Windows, laissez-la finir, puis, tout en appuyant sur MAJ, éteignez_le (voir ci-dessus). Cela éteint vraiment Windows et ne le met pas dans un truc de veille hybride. Maintenant, vous ne devriez pas avoir de problème lors de l’installation d’Ubuntu. | ||
