Re: Image recognition using a raspberry pi camera?

I don't think MPEG-7 is what we're looking for. The PyImageSearch guy seems to have great info but it's not free (which is fair enough); he sends you heaps of email advertising his books and content to buy from him... Anyone got any FREE guides on how to make a neural net image classification system...

discover which apps are available

I just have a noob question:
How on earth is anyone supposed to discover which apps are available with an apt-get install command?
Thanks

Two Pi servers coexisting

Hi People, Is there anyone who can suggest a good way to have two Raspberry Pis, both acting as Apache servers, behind the same firewall? I have one set up already, and I just used the classic port forward so that all requests to port 80 go to the pi's address. But what I really want to do is point ...

Re: Help - I'm being hacked!

Well, thanks everyone, the changing of the port pretty much stopped the attacks in their tracks. Installed fail2ban too. This is exactly what I wanted. Thanks also to others who provided a wealth of other suggestions for many of us beginners to look into. I understand that the Raspberry Pi folks wan...

Re: Help - I'm being hacked!

Thanks Ernst. I like having the pi on the net with ssh and vnc.
But I'll see about using keys - not sure right now how to do that.
This seems to be a distributed attack from lots of IPs, probably infected PCs and IOT devices.
Thanks guys.

Help - I'm being hacked!

My pi is connected to the net and SSH and VNC are enabled, which I love. But looking at the log var\log\auth.log I can see that I am being hit in bursts of 6 attempts every couple of seconds. See a sample below. It's only a matter of time before brute force wins. :cry: It seems pretty obvious that t...

Re: Accessing SSH outside local network

Thanks, that's a great troubleshooting tool. The port was open. My outside IP address was wrong. The dynamic DNS I set up is not getting updates from the pi or the router and even when I update the address manually on no-ip.com, the domain name does not work. Well 10min later it decided to work (i g...

Re: Accessing SSH outside local network

Port forwarding is a tricky subject. Google How to set up port forwarding and see what I mean. :idea: If you intend to do a lot of remote access from outside your Home network you might want to consider subscribing to a Dynamic DNS service like NOIP or DYNDNS. These services allow you to choose a U...

Your post is a little unclear but it sounds like you have a sweatshop of 100 sewing machines and you want each slave to hit a button when they're done sewing a pair of G-star whatever pants so you can keep track of who is sewing the most... or something. You would use a keypad scanning technique.. a...

Re: Pi3 internet browsing and Youtube performance

The Pi 3 crashes every time when putting YouTube full screen. Does anyone know why? Or what to do when it crashes and restarts crashes restarts crashes restarts like 6 times in a row. This is out of the box with Raspbian Noobs -I haven't installed anything else or changed any of the settings.
