Gillespie thought he was finished for the day but, as he tells the story, "Ricky Ponting, the world's best batsman, asked me to do his job as well. He just felt that the Bangladesh attack posed too many threats to risk him at number three."

He was given the role as 'nightwatchman' and when Matty Hayden holed out, Dizzy went out to face the last seven overs and protect his captain.

Not only did he do that but by Day 4 of the Test, Gillespie reminded the Bangladesh players of the original Dizzy Gillespie's 1988 album when he batted Endlessly to reach a double century. The only nightwatchman to do so. He was named Player of the Match and the Series - and was never selected to play for Australia again.

In May 2016, the late editor of an Australian Fairfax publication, Brian O'Flaherty, published my first Tech Talk column. I had been writing IT columns for IT audiences since 2004 but this was my first serious foray into the general populace. Today sees the publication of my 200 ^th column so, just like Dizzy, a double century that I wasn't necessarily planning upon when Brian asked me to submit my first column. This column now has a weekly home in 140 mastheads.

My columns have explored mobile radiation and SAR measurement through to current 5G conspiracy theories. I have discussed methods of international roaming and Internet access everywhere from homes to planes. Cars are a favourite - electric; hydrogen; autonomous; driver assisted and more. I have reminisced about video cassettes and vinyl records and my old BlackBerry through to games such as Wolfenstein and Crash Bandicoot or the tech used by 007. Electronic voting and misinformation on social media sites have been touchy subjects for many people who are interested in their politics.

Rumours on new technology are revealed and then, after launches, the latest products are dissected to give you the latest information to make decisions on your technology.

Announcements at international conferences are broken down into what may be relevant to the real world. Technology gift ideas are explored - they may be Christmas gift ideas or what I am buying my wife for her birthday.

If it is technology I can see society still talking about in five years then it has a place in a Tech Talk column. Hopefully, unlike Dizzy, I will continue on to my triple century and well beyond.
