Re: How to change 32 bit packages to default architecture on a raspberry pi 3

What operating system are you actually trying to install? Where did you get it from? Get a new SD card. Download Raspbian from here: https://www.raspberrypi.org/downloads/raspbian/ Follow the instructions. This will work. Unless your Pi is broken hardware wise. Which I doubt, This procedure has work...

Re: Raspberry pi 3 RTOSes

More or less what? Real-time performance is possible on a pi running Raspbian. For some definition of "real-time". Discussion I linked to above. Personally if I were messing with a lot of PWM and other high speed real-time signals I would consider using a separate MCU to do that. In particular the 8...

I would wager that trying to continue with cloning and using that quite possibly messed up image would be a lot more hassle than starting over.

Re: If I image a permanently-locked SD card, will the image be locked?

No.

But I would not bother imaging that locked card.

Why not just get a new card and put a fresh raspbian image on it.

Then just copy whatever files you need off the locked card by using a card reader.

Re: Raspberry pi 3 RTOSes

What are your real-time deadlines exactly? It's meaningless to state real-time without specifying that. If you happen to be using a four core Pi you can isolate one or more cores from any Linux kernel scheduling activity and dedicate it to doing nothing but your real time task. With these techniques...

One-off anecdotes are wonderful. Here is mine: A Pi 2 and a Camera set up to take snap shots and serve them up over HTTP. Worked fine for half a year or so then failed.

Luigi3711, I have gotten another SD card (32 GB Samsung Evo Plus) and I still have the same problem interestingly enough. Therefore it could be something with the rpi unit itself. I will have to replace it. It would be very helpful if you would state exactly what you have done and exactly what the p...

You already have your answer from Dougie above: Your best bet because you've made a total mess is to scrap your SDCard and start again with a fresh copy of plain Raspbian 2017-11-29. When you have that installed: Do not mess with trying to change the architecture of anything. Do not try and install ...

I'm not sure what USB has got to do with this. Hard drives, or any storage, fails all the time.

That is either very brave or you don't value whatever i...

Seems to be quite a common practice to use nginx as the public facing web server and have it proxy pass requests to back end services on different machines or different ports on the same machine.

@wh7qq,

Perhaps. We can swap anecdotes forever, as you so aptly demonstrate, and never arrive at a conclusion.

@W. H. Heydt

Do you have any links to SD card data sheets or other concrete information?

Re: Installing newer version of NodeJS on Pi 3

I have no idea about whatever OS the Pi-top uses. But if it is based on Debian/Raspbian then as far as I can tell it is normal not to get npm with a node.js install. Which is really weird and stupid but there we are. At least that was the case last time I checked.

Use curl or wget. The examples shown have been correct.

Re: Is it worth getting a better RPI for a vpn server?

This looks like SPAM for some Russian web site.

In case not. The pi is not a good choice for intense network activity i.e. a router. It has pretty slow network interfaces.

I really don't want to help anyone access anything as stupid as 9gag. Especially not from school.
