Big number

For 2023 (and 2024 ...) - 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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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))

Big number

I was reading that the president of Google recons there's 5 million terabytes of data out there to index ... and that they're only a tiny part of the way into it. What does that look like?

5000000000000000000

Hmmm

Custard:

5000000Tb to bytes = 5497558138880000000
Shurely?

What we call a 'b*stard' number as it contains two bases. Base 10 in the 5 million and base 2 in the Terabyte part assuming that 1 Terabyte == 1 Tebibyte (2^40).
At least they didn't say 5 Billion Gigabytes.. You would have to guess they mean a US billion as opposed to a UK billion ;-)

US 5000000000Gb to bytes = 5368709120000000000
UK 5000000000000Gb to bytes = 5368709120000000000000
If I'm not mistaken...

Perhaps they mean 5 Exbibytes
5Eb to bytes = 5764607523034230000

(Corrections welcome, I sincerely hope these answers are correct as they come from code I use in a live storage allocation application)
