Ceci est une ancienne révision du document !
Welcome back to another edition of Questions and Answers! In this section, we will endeavour to answer your Ubuntu questions. Be sure to add details of the version of your operating system and your hardware. I will try to remove any personally identifiable strings from questions, but it is best not to include things like serial numbers, UUID’s or IP addresses. If your question does not appear immediately, it is just because there is such a lot, and I do them ‘first-come-first-served’.
Bon retour parmi nous pour cette nouvelle édition de Questions et Réponses ! Dans cette rubrique, nous essayons de répondre à vos questions sur Ubuntu. Assurez-vous de nous donner les détails concernant votre système d'exploitation et votre matériel. J'essaierai d'enlever tout ce qui pourrait vous identifier personnellement dans vos questions, mais il vaut mieux ne pas inclure des éléments comme des numéros de série, UUID ou adresses IP. Si votre question n'est pas publiée tout de suite, c'est parce qu'il y en a beaucoup et j'y répond selon le principe de « premier arrivé, premier servi ».
I was planning a project for a client and the outcome was four weeks to install network points, wireless AP’s, cabinets & switches, and power plugs mounted under the desks, as well as replacing lights with low power LED lighting and rewiring the building so that a generator can charge the UPS and the UPS can run the building. Channels had to be built, etc, etc. The client gave me a ‘NO WAY’ that it can take that long, they need to move in at the end of the week plus maybe two days… There is a method to the madness. When the power is done, the plugs can be mounted, in turn the cabinets can be populated, etc. When you work out of order, you end up with things that need to be done afterwards. This is not ideal. Also, every project has a gremlin, hidden somewhere waiting to jump out at you - and you need to make allowances for that too. In this case, the basement was locked and no-one had a key or access. Obviously, the current power cables ran through there, forcing us to build other paths. This is why I like recipes; when I use a cake recipe, I never end up with soup. You know your system, you know your workflow. When something breaks, follow a reasonable “recipe” for problem determination and repair. Ask yourself, what changed lately. If nothing had, it may be a hardware issue! Something as minor as a bubbling capacitor in a power supply may cause an issue down the line. Go with what you know, before trying something exotic.
J'organisais un projet pour un client et le résultat était qu'il fallait compter quatre semaines pour installer des points réseaux, des points d'accès au WiFi, des armoires et coffrets électriques, des prises électriques sous les bureaux, ainsi que le remplacement des ampoules avec des LED à basse consommation. De plus, il fallait refaire toute l'installation électrique du bâtiment afin qu'un générateur puisse charger l'alimentation sans interruption et que cette alimentation puisse gérer le bâtiment.
