Chip and pin is not nirvana

In the UK today it is D-Day for Chip & Pin.

Basically, all UK credit and charge cards should now be fitted with a chip and when you pay for goods with your chip and pin card, you have to enter a pin number, rather than provide a signature.

All of the bugs in the process have yet to be ironed out - many of us, for example, still don't have chip and pin cards, even for our most regularly used cards. We can still sign, but the secondary problem here is that some stores are refusing to accept non chip & pin cards for transactions. There is no reason for this - except badly trained staff and a campaign by APACS that gives the impression that everything is OK.

Open wifi networks from a train

I've just traveled on a long journey (4 hours) by train. It may be slower than plane, but it feels much more relaxed, there's a lot more space (up in first class we shared the entire carriage with about 6 other people), although the rest of the train was a lot busier, but most important of all, it lets you see a lot more of the country and the countryside, including those areas where you are just a few yards away from the craggy rocks of the coast and the North Sea.

It also gives you a much better opportunity to do some work - I had a massive table at my disposal, my own standard power socket and, had I been on the right train, the opportunity to use the free wireless (chargeable in standard) for Internet access for the entire journey duration.

Offices and self generation

A couple of weeks ago I wrote about using personal power devices (such as CHP and wind turbines) to provide the power for your office and help lower those escalating power bills.

Now an article at the BBC describes how some companies and individuals are doing exactly that, including the Co-operative building in Manchester.

They expect to save 4% by having a mini farm of turbines on their roof, and up to 30% by using a combination of other 'green' technology.

Hotel network cables

I'm on the road again, although this time mostly for pleasure, and I'm wired up to the hotel network. Interestingly, net access is free in the rooms, and through wireless in the rest of the hotel, also free. Compared to the $10-$20 per day charged by most hotels I've visited and I'm both surprised and pleased.

The wireless option is obviously great and lets me work pretty much anywhere, but in the room (I'm on the top floor, basically a converted attic) it's wired only.

I don't have a big issue with that, but why do they supply such short cables?

I know they expect me only to work at the desk, but there's also a bed and a small seating area (in an otherwise huge room), but the cable is probably just 3-4ft long and its barely long enough to reach the desk.

Debugging Perl in Eclipse with EPIC

Back in September 2005 I presented two sessions at EclipseWorld on EPIC. My first tutorial based on the topics and techniques covered in the first session was released in January, and now the followup, covering debugging Eclipse is available too. Here’s the outline blurb:

Debugging Perl applications can be a frustrating process. Many Perl programmers rely on print statements and so-called “postmortem debugging.” Others use the built-in Perl debugger. Neither provides a coherent execution environment for monitoring the execution of a script, and neither supports the debugging of a Common Gateway Interface (CGI) script during execution. In this tutorial, we will look at the debugging functionality offered by the Eclipse Perl Integration (EPIC) plug-in for Eclipse, which offers a rich debugging environment available and integrated with the EPIC Perl development environment.

You can also read the first tutorial, although it is not really required before reading the new How to debug Perl applications with Eclipse.

Multi-touch interaction

I'm sure many people have seen sci-fi movies that involve individuals using touch screens in much more intelligent ways than we see available today.

Even the interface in Star Trek (which is often based on a touch screen with multiple layers and levels) looks more interesting than the interfaces available, touchscreen or otherwise.

Now a video has surfaced (through digg) of the work being done at NYU Media Research Lab on multi-touch interaction.

Downloading music is not always cost effective

I was reading Get ripped off at iTunes store for low quality 128bit by Alex Scoble, and I'd like to offer a much cheaper, better quality alternative for obtaining your music.

Rather than buying the music through an online music store, which provides no control over how the music is ripped, or its format, not to mention the DRM issues, buy the music on CD.

I know what you're thinking - it'll be more expensive. But rather than buying the CD brand new, buy it second hand (Amazon is a great source here) or through special deals (3 for 2, or 4 for $10) specials. I can't remember the last time I paid full price for a CD - in fact many of the CDs in my collection are ones bought for as little as 99p (about $1.75). Even on Amazon I generally look to pay less than £5 ($9) for a CD, including postage, and often get them for as little as £1.99 ($3.50).
