+ | **I really do not understand how all these cellphone repair shops in all the malls make ends meet. Who buys from them? I stopped in at one to get a charging cable for a raspberry pi 3, and the guy behind the counter said to me, “150 bucks”. I was like “what? Are you crazy?” And he never batted an eyelid and said, “it’s a good quality cable”. I have never been back to one of those shops since. You see, I used to work for an OEM and 150 bucks would probably get me 150 cables at cost, and if I took the cheapest ones, I’d probably get double that for 150 bucks. If it was a lightning cable I’d probably pay ten times that, LOL, but that is not the point. This is the issue I have with proprietary crap. It is designed to get the most money from you, not innovate to be the best, protected by some law. While I understand copyright, I think it stifles creativity, as you need to look over your shoulder constantly, worrying if someone will sue you for something they vaguely described in a patent they never made. Open source allows you to innovate, but we are also reaching a point where open source is not open source any more, as it has this or that type of “license” and actually has some corporate behind it with an army of lawyers, who make money off that alone. Or... they say they are open source but leave some part proprietary, | ||

- | Q: Hi! I’m Running Ubuntu 22.04 Cinnamon respin and I’m very happy with it so far. There is just one small thing that I cannot seem to wrap my head around, and that is when I close my lid on my HP laptop, and I open it again later, all I have is a flashing underscore in the top right-hand-side of my screen. It used to work and I have not changed anything but do regular updates. So now I shut it down rather, but I’d like to have it suspend again. | + | **Q: Hi!

There was a write-up about it somewhere, but I cannot find it for you right now. | A: As far as I know, all you need to do when you see that, is press ALT+TAB, like you would when switching applications and your lock screen should appear.

Q: This may not be in your area of expertise, but I have to ask, anyway. The kids want me to get a wifi6 router. Those things that look like spiders. While I’m not sure if Ubuntu supports it, I know the Mac does. There is also the current router, that functions well and I don’t want it to lie in a drawer somewhere, wasting away or end up in landfill. Is there a particular model I need to look at that will support Ubuntu and Mint? What can I use the old router for? I have heard one can load open source firmware on them. | Q: This may not be in your area of expertise, but I have to ask, anyway. The kids want me to get a wifi6 router.

- | A: WiFi 6 is a standard, so as long as your WiFi card supports it, Ubuntu should support it. That said, make sure your WiFi card supports Linux, should you get a new one. Can I put a spanner in the works? Why not turn off the WiFi in your current router and buy a cheap WiFi 6 Access point and plug that into the router via cable, to replace the internal WiFi? That should save you a couple of hundred bucks and preserve your current router. Not all routers support other firmware or openWRT, you’d need to check with the make and model first. | + | A: WiFi 6 is a standard, so as long as your WiFi card supports it, Ubuntu should support it.
