The document discusses HTTP response codes that web servers send back when a webpage is requested. It notes some common response codes like 200 for OK, 404 for page not found, 301/307/308 for page moved, and 504 for slow internet. It also mentions less common response codes like 403 for forbidden access, 407 for requiring proxy authorization, and 418 for when the server is actually a teapot, which was an April Fool's joke. The document then shifts to discussing the Internet of Things and connecting appliances like televisions and refrigerators to the internet.

1. If you know about how the web works,
you know that when you request a webpage…

2. …you get sent back a response code.

3. “200” means everything OK, so you never see that one.
That’s why most people don’t know about these codes.

4. Occasionally you’ll get a “404”, meaning the HTML file wasn’t found.

5. Maybe you’ll get a “301”, “307” or “308” if the page has moved…

6. …or a “504” if the Internet is a little slow today.*
*much more of a problem in Australia than here in Japan!

7. You might get a “403 - Forbidden” if you’re not supposed to access that page.
Or a “407” if you have to authorise your proxy connection.

8. Or maybe you’ll get a “418” if the webserver is actually a teapot.

9. True story, 418 is the response code if the server is actually a little teapot.

10. How odd…

11. This makes more sense if you look at the date the “Hyper Text Coffee Pot
Control Protocol” was published on.

12. April 1, 1998

13. It’s an April Fool’s Day joke.

14. But we live in an age when appliances like televisions and refrigerators are
connected to the Internet.

15. An age when an old April Fool’s Day joke starts coming true…

Getting the tie working was a very long and difficult process for a software guy.
I experimented with two boards designed for wearables, the Lilypad USB and the
Adafruit Flora.
Today, the tie is working off a Lilypad USB.

27. But is this the Internet of Things?
Well… funny thing about that…
The Flora board was the one I selected for the tie…

The “Backend” The “Frontend”

29. But is this the Internet of Things?
Originally the “backend” was hooked up to
Bluetooth.
The idea was a message could be sent to the
tie.
Like if an RSS feed changed.
And Moodle events can generate RSS feeds…

Adafruit “Bluefruit”

30. But is this the Internet of Things?
But…
Getting a stable connection was difficult because
of Unknown Reason X and “I’m a software
guy”.
Actually, I’m pretty sure Unknown Reason X is that
Bluetooth and the Neopixel LEDs are drawing too
much power at the same time. But I don’t know how
to fix that.

The “Backend” The “Frontend”
So let’s just quickly swap out
the backend so I at least have
something to show…

32. Oh noes
During debugging (on Feb 10th), I
actually broke a Lilypad USB.
This day sucked.
We found enough spare parts to sew
together another backend

34. It turns out I had the answer two weeks ago…
PunchThrough Design’s LightBlue Bean
❖ It arrived two to three weeks ago
❖ Didn’t play with it much trying to get
other demos ready
❖ Last weekend, four days before I left for
Japan, I started playing with it, and
realised:
BEAN + PYTHON = MOODLE RSS
THINGY I WANTED ALL ALONG
#MootJP15 @MillerTAFEScott

35. Getting back to the point…
So, this is pretty and all, but who cares?
It’s not about a tie, or a pair of gloves, or RSS.
The bigger picture is can we use IoT in eLearning?
#MootJP15 @MillerTAFEScott

36. Demo Time…
…kind of…
