Re: Powering a Raspberry Pi

Thanks for the advice, folks. (I've been having password issues that stopped me replying sooner.) I take your point, davidcoton, but I've actually got a powered USB already (it was a present - I wouldn't have gone for USB3 myself) and I was wondering whether I really had to plug the RPI into TWO mai...

Powering a Raspberry Pi

Is there any reason why I shouldn't power my RPi 1 B from a powered USB (3) hub?

I'm not that bothered about smoking the RPi, 'coz that would just mean I had an excuse to go out and buy a model 2, but a new hub could cost me more than the RPi.

I would also characterise the arguments over OOP as being over and won. Maybe the fight now is between richly typed languages and older languages with framework-provided rich types.


Can you explain that, please?

Re: Best first language choice

<t>My main complaint with Java (and similar languages - C#, C++, etc.) is that it requires a lot of "ceremony" to get a basic program working. Class and method declarations, types declarations, System.out.println, etc. Then there"s the extra complication of the compile/run cycle vs interpreted and l...

I\'m finding that the FORUM link above takes me to the Messaging page. (I\'m using Safari on an iPad.)
