Re: Ruby and a special URL doesn't work

As far as quotes go, that is correct. He is using single quotes on the outside, so he can safely use double quotes on the inside. I have no experience with "SiriProxy", so I cannot answer specifics there. But, to the question "can Ruby handle it", then answer is "yes". ...

Re: Why does the Pi draw constant current, unlike a phone?

The ARM CPU in the BCM2835 system-on-a-chip (SoC) used in the Pi does have that capability... [but] it will likely be some time for this to be implemented, and only then if a large fraction of users request it over things like the camera module, wished-for LCD display interface, and thousands of ot...

Re: Anywhere to get a Model A in US?

Man it is tempting but with shipping wouldn't it take a few weeks to arrive? I'm sure it varies based on where in the US you live, but for me in Oklahoma, I can say that it arrived in about a week. In fact, I've ordered from US companies (I'm looking at you Newegg) and had shipping take longer than...

Re: Anywhere to get a Model A in US?

They are not sold in the US yet, sadly.

I gave up waiting and ordered mine from ModMyPi.com. They are a British company, but for a very reasonable fee they shipped two model As to me here in the US.

Re: Need Cheaper Pi

The cheapest way? get a power cord and an Ethernet cable and ssh into it. Edit: sorry I forgot the SD card so many of them just lying around. I'll second this approach, though with a WiFi adapter instead of wired ethernet. I've even uninstalled X11 on all my Pis, meaning 2GB SD cards are usable and...

Re: Kickstarter Identity theft

You make a very good point, and I agree. I was mainly trying to illustrate that it's not an "easy" problem. It's a problem that does involve people, paper work, and time. I've never ran a project on Kickstarter, only backed them, so I had no clue you had to provide a credit card to them. L...

They aren't supposed to store the CVV value, only to verify it immediately on receiving it but I wouldn't be surprised if some merchants screw that up. They will store the rest of your credit card details. Very, very true. Not that Farnell does (or does not) practice that, but as a software develop...

Okay, so I will probably buy from element 14 if I do. Now what sites have the best prices and shipping on accessories for the RPi? One thing to keep in mind is that many of the sites that sell accessories also sell Pis. Seriously, the premium that 3rd parties charge for their Pis are often cheaper ...

Re: Best Site to Buy from when Shipping to US?

If you are looking to keep the price for the model B at $35, the only places to buy them are from the official distributors (Element 14 & Allied). I've never purchased from RS/Allied, so I'll let others comment on them. I purchased my "B" from Newark/Element14, and was mostly pleased. ...
