The ups and downs of socio-technical networking

Last Sunday, in the spirit of celebrating the continuing success of the great leap forward taken by America's Founding Fathers 334 years ago, my wife and I enjoyed a pleasant cocktail outside a hotel in Central London.  In the bright sunshine, I inadvertently texted a message intended for our daughter to my Twitter short code, so it went to my TheFilterGuy stream on Twitter.  I realized straight away (the reaction time not having yet been curtailed by the cocktail), and used the Twitter app on the iPhone to delete the offending (but not offensive!) message from the timeline.

However, human-scale reaction times are just no match for the propagation behaviour of modern social networks.  You can delete something from the Twitter public timeline, but Google seems to cache the timeline dynamically, so what you typed will get 'crawled' eventually.  Sure enough, next morning my deleted mis-Tweet turned up both as a Google Alert and in a LinkedIn summary emailed to my wife... how embarrassing!  Of course, it could have been much worse; I could have been exchanging personal information, or confidential trade secrets.  Check before you click!

But there's definitely an upside.  I get a buzz from helping people to solve their difficult signal management problems, and it's encouraging to reflect on how easy it is these days for us to bounce questions and answers around.  If you have a question on filter or system design, there are many ways for you to punch that question right through to my beloved iPhone.  Of course, everyone has some limitation to their bandwidth, I can't give an instant answer to every question.  But it's often really quick and easy to point people in the right direction with a short email; it doesn't take a magnum opus.  So, don't be shy - if you're stuck on some filtering task, drop me a line, on Twitter, or LinkedIn, or email (filterwizard at cypress dot com).  My response time will probably be inversely proportional to the interestingness of your question - the Bandwidth Theorem at work again, maybe!  Always happy to get subject requests for my Filter Wizard column as well.

Right, now back to the lovely pseudobandpass filter I'm designing for the front end of a PSoC3 solution which replaces an old chip that just suddenly became hard to get.  I can remember the days when component stores took up half a factory... now, you just need a few tubes of PSoC devices and a good "capsule wardrobe" of basic passives, diodes and transistors.  Maybe it's time to have your own "Independence Day" moment!  best - Kendall
