For 2023 - we are now fully retired from IT training. We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.
Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!
I am also active in many other area and still look after a lot of web sites - you can find an index ((here)) |
How far away is that server?
Ever wondered how far away a server is? You can get a clue from the ping time taken as internet traffic is fast but not instantaneous. No doubt someone can up with some scientific figures and speed here ... but seated in England, I've found today:
375ms to a server in Australia
170ms to a server on the West Coast of the USA
26ms to a server that I think is in Franfurt
less than 1ms to a server on my own LAN. (written 2005-09-10, updated 2006-06-05)
