For 2021 - online Python 3 training - see ((here)).
Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.
Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.
How does your browser find out about itself?
• Does this browser accept Cookies?
• Does this browser accept Flash?
• What processor chip type is in the computer hosting this browser?
• Will this browser run Java Applets?
• How wide is my window?
object contains the answers to four out of the five questions above - there's a source code example [here]
and you can run that example [here]
The Window width (and other things about the document that's displayed within the browser) are in the document
object; see [here]
for the source of an example, and run it [here]
The questions I started with is "What is my IP address", and I've yet to find a full and proper answer to that one.
I can actually find out the IP address that the server sees me arriving from via PHP, looking at the $_SERVER["REMOTE_ADDR"]
variable, and writing an AJAX query. But that reports the IP address from the server's perspective, and not the IP address that's being used on our internal network behind our router. In other words, I'm connected to my local network at the moment as "192.168.200.199", but that's rewritten to "22.214.171.124" when I connect out to the Internet. My server reports back 126.96.36.199, but I really want to know in my browser that I'm at 192.168.200.199.
- which would let my page call up a local server as well as the remote one, but that's a fudge which relies on me someone opening a security hole (see Cross site Scripting
, and I think the wise decision would be for me to look for a cleaner work around to meet my original requirement. (written 2011-01-11, updated 2011-01-12)
