Re: Two character username

Yup. When I try to resend the activation mail I get "Information: The e-mail/username information submitted could not be found." - I *have* confirmed that the username and email address match what I registered with. When I try to login, I get "You exceeded the maximum allowed number of login attempt...

Two character username [solved]

'ello, I'm having some problems trying to log into the forum at the mo - I think it's something to do with having a two character username, and since an upgrade to the forum software some time ago, there seems to be a minimum limit of three chars. Using this machine, it's OK, I guess because I logge...

Re: Tenda WiFi Dongle - Trying to get Internet Access

Hi, I'm using exactly the same wifi dongle, and it works nicely. First thing to do is install the firmware-ralink package with sudo apt-get install firmware-ralink. Once this is installed, plug in the dongle, and then use lsusb to check that it's recognised. You can also use iwlist scan to make sure...

Re: Connecting to the network - Issues

I've still got my NSLU2 somewhere :) It was the device that first got me interested in low-power devices. I progressed from there to a Sheevaplug, and then to the RPi. I'm pretty sure I'm not the only one :)

Re: Connecting to the network - Issues

Is it just the web browser, or anything started under X? For example, what happens if you start X, then start an LXTerminal, and then ping www.bbc.co.uk from there? If it's just the browser, it could be proxy settings, rather than an actual connectivity issue.

Re: Weather Pi

I have something very similar - a couple of DS18B20 sensors, and a DS2490 1-wire to USB bridge. The output is run through GD with a bit of perl to produce a graph of the temperature inside, and outside my shed: http://www.ronketti.org.uk/temp.html I'm also using net::twitter::lite to generate a twee...

Re: The Official Raspberry Filling : Call for Contributions

However - at key stage 3 (11 - 14) I need something which is simplified and fun and would allow them to experiment with core principles of communication without becoming overwhelmed by terminology and obfuscation. Imagine a kind of desert island scenario with a small number of working computers how...

Re: The Official Raspberry Filling : Call for Contributions

I'm happy to help out here too, for broadly similar reasons. My thinking is that there are a lot of children out there (my own included) who just equate 'the internet' with firing up a copy of Firefox. Using the Pi as an educational tool to show how things hang together, and setting up basic DNS, DH...

pi on a pi

Here's something of passing interest... I've just been playing with pi_css5 [1] to see how quickly my pi can calculate pi...

Re: 1 Wire Sensors for home heating control

<r>I'm currently logging temperatures [1] on arm ARM powered Sheevaplug using a DS2490 and a pair of DS18B20s. The logging side of things is pretty straightforward using digitemp [2] which I've tinkered with a little bit. So the logging side of things *should* be pretty straightforward. I guess I'll...
