- | I called Dell support on behalf of one of my clients. Dell support is 50/50 – sometimes you get good service, sometimes not. The client rents thousands of machines worldwide, and works very closely with Dell to have a unified IT infrastructure. As usual, I tried to speed up the process by telling the poor first-liner what I had done. However, this was one of those idiots who was going to treat me like a home user. I had to go through everything manually with him on the phone. (What testing VGA modes has to do with a faulty USB-C port is beyond me). I tried to explain to him that we have tested by process of elimination and come to the conclusion that the laptop’s USB C port was indeed faulty. However, this guy was not budging. He wanted us to change drivers, etc, which we (the client) are not allowed to as it is controlled via the client’s global IT in combination with Dell. There is monitoring software that will remove the PC from the network if we change anything – as it will be non-compliant. Here we got stuck, they refused to help until I updated the drivers. The thing is, we have 100’s of similar laptops with everything identical, so chances of the driver causing one machine to be faulty are tiny. Then the guy asked for a photo of the port as he was sure it was damaged. This was not my first rodeo, so I sent him a picture of mine – my laptop being less than a month old and the port never used. (The other laptop was about 2 years old). Dell does not want to waste resources on older laptops, and while I understand that, I have a 3-year on-site warranty that is paid for. The reply was that the port was physically damaged and they would void the warranty. This is where I lost it and became a Karen. His manager tried to tell me that it was faulty too at first, (trying to cover) until I told him there is NOTHING wrong with it as it was mine and unused. Only when they realised they had been duped and that I was on to them from the start, did they want to see the other one, which, by-the-way, looked the same. One can’t really see from a photo if a USB C port is damaged internally, only externally, like bent or broken edges or centrepiece. I wonder how many clients they have done this to, to be so confident in trying to BS me into accepting some first liner’s opinion. They tried hither and thither, and tried to pull EULA, etc, on me, but I did not give in. Don’t let someone try to tell you because you run Ubuntu your warranty is void or they can’t assist. BS back, tell them you installed Windows and your driver is now the version they want and it is still faulty. If you are 100% confident in your diagnosis, stick to your guns. (BTW, they replaced the board and it has been OK ever since, but do check that too, Dell does not always send new parts, a lot of them are “refurbished” and may have other issues). | + | **I called Dell support on behalf of one of my clients.

+ | Dell ne veut pas gaspiller des ressources sur des portables vieillissants et, tout en les comprenant, j’ai une garantie sur site de trois ans, qui a été payée. La réponse était que le port était endommagé physiquement et qu’ils annulaient la garantie. C’est là où j’ai perdu la tête et suis devenu une BCBG versaillaise. D’abord, son chef essayait de me dire que c’était défectueux (essayant de le couvrir) jusqu’à ce que je lui dise que ce port n’avait RIEN, car c’était le mien et inutilisé.

Q: Smorg, [10.03.21 11:22] I know it’s not 100% Ubuntu, but I want to put it in my VM on Ubuntu, so it may count. Why would anyone want to use Openindiana? | Q: Smorg, [10.03.21 11:22] I know it’s not 100% Ubuntu, but I want to put it in my VM on Ubuntu, so it may count.

- | A: Legacy, mostly, I’d say. People like to have at home what they use at work. Thing is, commercial software for it is like hens’ teeth, and that is what is important at the end of the day; if nothing new runs on it any more, would you want it? Linux has been “Rock-solid” for me moreso than Windows 10, but that does not say much. Also remember, it is based on Solaris, proprietary OS, meaning open source stuff for it is also minimal. But go ahead and install it, you may like it. | + | A: Legacy, mostly, I’d say. People like to have at home what they use at work.

+ | Q : Sous Windows, je peux voir l’historique des réseaux WiFi auxquels je me suis connecté par le passé. Sur mon portable, je peux cliquer sur l’icône WiFi, aller sur connexions et les voir. Je suis cool avec. J’ai construit un scanner WiFi sans tête avec un Raspberry Pi zero à partir d’un tutoriel et je me demandais si je pouvais voir les réseaux ouverts auxquels je me suis connecté, mais à partir de la ligne de commande. Il n’a pas d’environnement de bureau. Je peux en installer un, mais je ne veux pas le faire. | ||

+ | R : Pour la plupart, je dirais Legacy (c’est dépassé). Les gens aiment avoir à la maison ce qu’ils utilisent au boulot. Le truc, c’est que les logiciels commerciaux pour cela sont aussi absents que des dents chez une poule et c'est cela qui est, en fin de compte, important : | ||

A: Don’t, in Linux a ‘minus’ is used to add options to commands. You may end up with something you did not intend. Use user/file permissions instead. Instead of trying to be clever, be smart. | A: Don’t, in Linux a ‘minus’ is used to add options to commands. You may end up with something you did not intend. Use user/file permissions instead.

+ | **Q: Just a quick question about LibreOffice in Ubuntu 18 vs 20. When I paste via “paste special” and “unformatted text”, something odd happens. The character fonts will assume my document fonts, but the spacing or line width will not. I noticed this while editing a document on my wife’s Ubuntu 20. It is very annoying. I can delete the line and press enter for a new line and the spacing – by this I mean the space an empty line takes up, will be completely different. This throws off everything else you want to line up. Then two lines further, everything is fine again. Like I don’t have enough grey hairs already. | ||
+ | A: What you can try is select everything CTRL+A, click on ‘Default style‘ top left, then set your fonts and font size again. When copying and pasting from browsers, people try to insert hidden nonsense, designed to make your copy/paste life difficult. When using copy/paste from a browser, you can turn off javascript, that may help. You can also make sure you do not select any empty spaces. You can also copy/paste to a plain text editor, and there select the text you want and copy/paste that.** | ||
