Attending a Tweetup tomorrow

by Leave a Comment

Tomorrow night, I’m going to attend an Oxfordshire Tweetup at the Fallowfields Country House near Abingdon.  I’m not sure what to expect, but I saw it was coming up and thought I would check it out.  A tweetup, as I understand it, is just a bunch of Twitterers getting together to meet each other.  I follow a few people in the Oxfordshire area (they actually help me by letting me know when the roads are bad or if there is anything interesting going on in the area) and it would be nice to meet them.  I’m not sure what to expect really, but it will be nice to meet some new people.

A few years ago, when ECademy was at it’s prime, I attended a local networking evening.  It was okay, but it was really a room full of people trying to sell themselves and their companies.  I never met so many life coaches as I did that night.  But it wasn’t awful—and i met some nice people who I spoke with afterwards.  I’m hoping that the tweetup is not so business-focused.

I’m looking forward to it.  I’ll let you know how it goes.  If you live in Oxfordshire and want to attend, the url to register for the event is here: http://twtvite.com/mkp8da

The Virtual Revolution

by Leave a Comment

BBC started airing a very good documentary about the internet a few weeks ago called The Virtual Revolution.  I finally watched the first episode just the other night.  It’s amazing how much has happened in such a small time.

Google was incorporated in 1998 (went public in 2004).  Youtube started in 2005.  Twitter in 2006.  The World Wide Web was created in 1990 with the first web server being created by Tim Berners-Lee in that year.

It was a fantastic documentary and it really makes you think. 

We are still very much in the beginning of all of this.  There are still things to be done that no one has thought of yet.  We still haven’t reaped much of the benefits that the improvements in communication channels will have lent to science and medicine and as much as the internet has changed all of our lives, I’m sure it’s nothing compared to what’s to come.

I routinely chat with people in China and India (and back home in the States) while visiting offices here in the UK. In high school, these places all seemed so far away.

This twenty years of the internet will one-day seem like just a blip to us.  One day years in the future, people will talk about how the newspapers and music industries cried foul before they found their own way.  We will talk about the quaint days of waiting for our favourite TV programs to be aired.  Soon, we will look back on Twitter and Facebook the same way we look back on the old newsgroups (it was all so crude!).

The other day I found myself falling into the trap of thinking that everything had been invented already.  Surely, there are no new opportunities out there because they’ve all been invented.  Or, someone is already working on them.  But the truth is that we’ve hardly scratched the surface. 

There are still things that aren’t quite right in technology.  Still loads to do.  For example, as much as webcam chat is fantastic and a nice novelty, it’s still too complicated to get “ordinary” people to use it. 

As much as things change, we still think in old terms.  Artists still come out with Albums, even though we can buy and download only the tracks we want.  Why do we need the album grouping?  We still have business people who think they need to fly thousands of miles to have a meeting in another office, because we haven’t found a method of communication that is better an 8 hour flight.  Too many of us still get up in the morning and drive or take a train to an office building to do work that could easily be done at home.  When we get to grips with some of these new realities, we will start thinking differently and even more innovation will come.

I was reading the xkcd comic strip (if you haven’t read it, you’re missing out—http://xkcd.com), and saw this this strip:

2003 wasn’t that long ago. Or maybe my age is just catching up with me.

The scary thing about Silverlight . . .

by Leave a Comment

The scary thing about Silverlight is that you are one security threat away from losing your clients.  One thing that I’ve thought a lot with the problems on IE lately is that people who wrote “Only-for-Internet-Explorer” websites did not give their users the option to switch browsers if they felt unsafe due to all the security flaw hype.

A little common sense and a knowledge of web standards and it’s easy to write HTML that will look good and be functional in all browsers.  Still, in my experience, too many developers are choosing a platform and sticking with it—most of the time that is IE.  It’s easier to test one browser, it’s easier to tell a user to use the browser that’s probably already installed on their pc.

Flash and Silverlight are different than HTML—they are runtimes which are allowed to run inside the browser—kind of like how Java applets used to be able to.  They are executables which run compiled functionality on your computer.  They are cross-browser—but not like html is cross-browser.  When I look at a Silverlight or Flash app on my pc, it’s always the same runtime working.  Silverlight is a few years old and really starting to look like Flash—allowing Microsoft developers like me to get more fancy and provide far better functionality for our users.  Silverlight runs on Windows and Mac, but has ignored the Linux landscape (there is an open-source Silverlight runtime called Moonlight being developed for that—but I consider it a snub).

In the world of web development, I think Flash and Silverlight are “cheating” at cross-platform compatibility.  Everyone has accepted Flash (except the iPhone/iPad), but the jury is still out on Silverlight.

Silverlight and Flash are great in that they move a lot of the processing to your computer and free up resources on the server from which they originate.  But they also increase the responsibilities of they client over the server.

Security flaws are found all the time.  We all scramble around and try to fix them when they come up.  As a software developer, I like the idea that I can apply a patch to a server and be done with it.  With client driven app, I need to make sure all of my users apply the patch (and do it in a way that lets them know that the app is safe—and not to panic).  Flash could bounce back from it (“You need it for Youtube, too. You should apply the patch”), but Silverlight is too new.

I’m often seduced by the cool things that Silverlight can do.  I’ve played around with it a lot and have written several small apps (including an animated Overpass ad on my blog), but I’m not ready to jump in head-first yet.
