NHS attack on WinXP; would an RP be safer?

Dear All, Does anyone work in or for the NHS to help comment? NHS has been attacked by WannaCry due to unpatched/clunky/susceptible Windows OS. Asking a frontline NHS doctor, her main functions are: - Access to patient details, bookings, history - Blood investigation requests and results (she says i...

David Braben was spot on with the word "obfusticated"

Some thoughts regarding obfustication of technology; which I think the Raspberry Pi movement is the saviour from. --------- At 0:36 seconds on the original BBC interview , it appears David Braben used the word "obfusticated". What a great word he used!

State of ICT for RPs in UK

Dear All,

What's the state of RP's with respect to their usage for projects for GCSE/A-Level IT projects? Can they officially be used / are they recognised?

I remember 14-15 years ago a minimum requirement was a 3 table join in MS Access ...

Thank you

Re: Swarm of RPs "calling home"

Thanks RPdom. Could scale it via AWS EC2 hosts. Could also open 1,000 ports via SSH on a master RP, I reckon. From a security perspective it would be good to decline a rogue member of the swarm trying to blend in. http://img.cinemablend.com/quill/f/4/8/2/e/2/f482e2b6d70a81785c9a692f8cf956569ec979bb....

Re: Swarm of RPs "calling home"

Get them to check in to a web server (that gives you a hostname, a domain name, a public IP address all tied the system serial number which can form part of your URL), you can then publish a special page ONLY when you want a specific machine to call home with a reverse ssh session. Good idea. Just ...

Re: Should the display unit come fully disassembled?

Bought another new RP and the got the other screen I had up and running on the first try; the cables on this on were taken out/in/out/in ... multiple times. Guess this is pretty conclusive then; a white screen can be due to a fault with the RP itself. The retailer has given me vouchers to half the p...

Re: Should the display unit come fully disassembled?

I meant to say that I powered the (newer) RP through it's usb micro input socket while it was connected to the touchscreen via the red/black cables; this did turn on the screen and the RP. I doubt this would have caused any issue; as I've done the same with the (older) RP that works fine with the to...

However ssh commands are really slow either via the ethernet or the wifi. So; why is the other (newer) ...

Re: Should the display unit come fully disassembled?

I bought a second screen and I get the same issue; the only difference that the white screen appears quicker. It came with the two cables going into the screen attached. Any thoughts?

Re: Should the display unit come fully disassembled?

Hi 6by9,

>>Does it boot normally on HDMI if you disconnect the display flex?
Yes.

I'm using NOOBs I believe, this is probably the issue. My apologies; I didn't realise Raspian means not having the shift boot option. I'll format an SD with a Raspian image and retest.

Re: Should the display unit come fully disassembled?

Thanks; when the cable is purposely disconnected the screen is blank entirely; not white.

When you got your screen was it fully disassembled? Did you have to manually insert the two yellow cables on this attached picture?
