Lots of companies wanted their projectors installed in the ceiling. One day I was at Mercedes Benz installing a projector. As they have their own IT, the jobs they don’t *want to do, like installing a projector in the ceiling, are outsourced. The issue with ceiling projectors is that the cabling can get too long, even if the projector has WiFi, some people need that cable. When the room is too big, like this case, the cabling cannot travel to the wall, then down the wall and along the floor back to the table. You start to get signal degradation. The alternative is to drop a pole for the cable to travel in. I asked my contact person why it had to go in the ceiling, as the pole was a bit contentious. They explained that the branch manager had called their on-site contracted IT to sort out an issue with him not being able to centre the image, with the projector on the table. It turned out that he had put his cup down, in front of the lens and the left hand side caught about 2cm of the cup... |

| A: You have Google and Chrome to thank for that; that is how they made Chrome so fast (their V8 engine) and obviously FireFox had to keep up or lose out. The other problem is the HIV of the internet, JavaScript. I don’t think you can turn it off any more, but you can try adding “noScript” extension and restart your browser? Or... get a lightweight browser that does not support JavaScript? | A: You have Google and Chrome to thank for that; that is how they made Chrome so fast (their V8 engine) and obviously FireFox had to keep up or lose out.

| - | A: Oof, that is Microsoft tactics right there! As I don’t use VLC, I have never seen that; on the other hand, the kernel is probably the OEM kernel, so you can get firmware updates from Dell. I would not worry about that too much, it does not mean that you won’t get updates to your kernel. It just means they will come in the regular channel instead of via pro. | + | A: Oof, that is Microsoft tactics right there!

It is not an on-off switch in the way that you are thinking (I’m assuming), or what I understand from your message.
