It's been a busy couple of weeks for gigs. On the assumption that at least some of my readers have similar tastes to me, here are brief reviews of the three gigs I've seen in the last couple of weeks.

Fairport Convention, Union Chapel, 20th Feb
This is the second year running that I've seen Fairport Convention on their "Wintour" at the Union Chapel. Last year was the first time I had seen them (which is bizarre for a band I've been a fan of for over thirty years). I can't quite put my finger on it, but this year's show wasn't as enjoyable as last year's. I suspect it was down to the number of songs taken from later Fairport albums that I'm not at all familiar with. Oh, and the arrangement of Matty Groves was very strange. The long instrumental that ends the song was unrecognisable.

Thomas Dolby and Friends, Union Chapel, 28th Feb
Something a little more up to date. This was Thomas Dolby bringing back together the band who had recorded and toured his second album, The Flat Earth. As an extra twist, the band (who haven't played together for over twenty-five years) didn't rehearse at all. They met on stage and worked the songs out in a two-hour "live rehearsal". They then went of for a brief break before returning to play a half-hour set.

The rehearsal was fun. And the band sounded great for a band eho hadn't played together for so long. There were also a few guest stars - including Trevor Horn who played bass on "Airwaves". The only slight disappointment was that the rehearsal overran so the final set had to be cut short.

John Cale, Royal Festival Hall, 5th March
I'm not a huge John Cale fan. I generally like the stuff of his that I hear, but I haven't really heard much of it. This concert had him playing the whole of hist album "Paris 1919" (from 1973). This isn't an album that I'd heard at all until I started to listen to it in preparation for this show and it's really not that representative of the rest of his music. But it's a great album and it was interesting to hear it all played live. It is, however, a rather short album (many were back in the early 70s) and that part of the show only lasted forty minutes. After a short break (and it was really short) the band returned to play another forty minutes of "the best of John Cale". I was pretty surprised to realise that I recognised most of these songs. All in all, a great night out.

CeBIT was way more successful than I expected. Thanks to Renee Baecker, the main organizer and the other people who were at the stand during the week we made a lot of contacts with individual developers and companies using Perl. We also talked to quite a number of people who have heard about Perl but never tried it and some people who never heard about it.

It was both very hard to be there standing 8-9 hours and almost constantly talking to people every day but it was also a lot of fun.

Originally we were requested to always have two people at the stand but it turned out that there were times when even 7 of the Perl::Staff members could not handle the number of visitors at the same time. We were lucky as our stand was part of the Open Source Lounge of 15 projects slightly out of the main stream of people. On one hand that meant many people walking along the main alleys missed it but on the other hand those who came by had more space and time to talk to us.

It was very heart warming to see people coming to the booth with no or even negative view on Perl and leaving with a feeling that they saw some really cool things they want to try now.

So what were we showing?

To people with now real Perl knowledge or people who used Perl 10 years ago we showed some modern Perl code such as Moose, MooseX::Declare and some related stuff. We showed them Padre so they can see you can write large desktop applications in Perl. We were also showing Catalyst, especially to PHP programmers but also to others who were web developers.

On one of the days there were two Foswiki developers and they showed their wiki to the people interested in that. I think OTRS got a bit less attention on our stand but they had their own booth very they made a lot of business contacts.

The strategy was simple. Some of us were standing in the alley and as people walked by we gave them a flyer and then started to talk to them. Obviously there were many who were not interested, we just let them go. I was the only presenter who did not speak German my strategy was to first ask them if they speak English. With many people it was clear that they don't know English well enough for a conversation or just prefer German. That gave me a chance to direct them closer to the booth to talk to "one of our other representative, who speaks German". So in fact I was acting a lot as the "catch man". I think it worked out quite well. When they were OK speaking English or even preferred that language then I kept the conversation going on. I asked what are they using Perl for, or if they did not know or have not used Perl I asked what other languages are they using and what kind of things are they using. That usually gave me an opportunity to ask if they would like to see some modern technologies in Perl. Most of them were interested so we stepped to one of the computers we set up (we had 2 sometimes 3 computers on our booth, which was high enough so we did not have to bend over to view the screens or type). There I showed them Padre, some code in Padre. Sometimes I showed a few pages from the Moose documentation and some small examples in Catalyst.

There were several people who were interested in Perl 6. For them I opened the web-page of my Perl 6 training slides and showed a few pages just to get them impressed by some of the nice features of the language.

Others, as I saw started by asking if the visitor "Knew Perl?" and from that point some kind of a conversation evolved in German that I could not follow anyway but that will be described by the other presenters. (Renee and Sewi have already written. All the reflections will be linked from the TPF wiki page related to Perl on CeBIT)

Some Improvements

There were a lot of things we could improve in our presentation. First of all none of us knew all the things we wanted to show and we did not have ready made pages to show them. So I'd like to have several slide-shows that we can load on all the computers we are using for presentation and that each one of us can use to present various technologies. After all I don't need to be an expert in Catalyst in order to give a short introduction and show a few examples, assuming they were already prepared and I went over the slides with someone who is an expert.

Same with the Perl 6 examples. Others kept referring people to me to show Perl 6 examples but we could have put together a few slides with interesting examples that we can flip though pointing out the nice features. Within the slides we could even have instructions - show the Rakudo web site now, or in other cases to show the web page of the CPAN Testers.

This of course needs more preparation and even some time before the event starts to show the slides to each other but it pays off as it will make the presentation smoother.

Even that does not mean there won't be questions that need some more thinking on how to answer. There can also be cases when the knowledge of the presenter ends and there are still questions but then we can find the other presenter who has deeper knowledge in that subject or refer the person to the community channels where can get more information. After all, a large part of what we would like to achieve is that our visitors will start learning more about these subjects and start to participate in our communities.

Pictures

Some pictures from the Perl stand on CeBIT.

Wow! People have been telling me this for years, but I was getting along OK with my old school Unix craziness:

$ find ./ | grep -v svn | xargs grep '\-\>Promotion'

But today I couldn't get that working. Something with xargs escaping of -> just refused to fly.

So I installed ack and ran it:

# cpan App::Ack
$ ack '\-\>Promotion'

And it found what I was looking for with zero fuss!

Control/SG.pm
335:      $self->Promotion($promo_hash);

View/Web/Phoenix/lib/Phoenix/Controller/SG.pm
2844:      $c->log->debug("you have these PromotionCode's already: " . (join ", ", keys %{$sg->Promotion}));
2846:      unless ($sg->Promotion->{$preauth}) {

Holy buckets! That is AWESOME! Thanks Andy!

I really have no energy to write much. The first day of CeBIT was a bit low on visitors but even that went quite well. I met with several people I wanted to talk. Especially interesting were the chats with the people from the Eclipse Foundation.

Today, on the second day, was a lot busier. Many people were walking around and many people came to the Perl stand as well. There are always 3-4 Perl::Staff people at the stand and usually they are busy talking to visitors.

Some PHP and Ruby developers came and we could show them interesting things that can be done with Perl, Moose, Catalyst and DBIx::Class. Many people also liked Padre, you know the Perl IDE

There were many people who said that the main problem they are facing is the lack of Perl developers and some of them told us that they are actually considering switching language because of this. It seems to them that it is easy to find programmers to many other languages, something that was the case with Perl as well a few year ago but now there don't seem to be any Perl programmers. I wonder what could be the reason of that? Where are does developers gone? Have they stopped using Perl and have they remove Perl from their CV? Are there many more jobs now filled by those developers without new developers learning Perl to fill the newly created jobs? Maybe the expectations from a Perl developer are now higher than 5-10 years ago so the same people who could counted as Perl developers 5 years ago aren't considered as such any more?

Anyway we have a lot more work to do in the coming days. I'll try to add some pictures to the next report.

Renee made some nice pictures of Perl on CeBIT

I've got another set of public training courses coming up next month. They will be held at the Imperial Hotel in Russell Square, London.

There are three one-day courses - Introduction to Perl, Intermediate Perl and Advance Perl. They're running on the 13th, 14th and 15th of April.

More details on my training web site. Hope to see some of you there.

p.s. Gabor has been kind enough to advertise the courses on his newly revamped CPAN Forum site - so the least I can do is to repay the favour and recommend that you have a look at the site.

When communicating with your customers, it's important to look at the information that you're sending from their point of view. Are they really going to be interested in the information that you send?

Earlier today I finally got round to unsubscribing from the MBNA marketing emails that have been annoying me for months. To confirm my unsubscription they sent me an email which started with this:

We are sorry that you unsubscribed from the newsletter OLB Non Enrolled Non Endorsed 1

Is there really any customer who is going to be even slightly interested in that level of detail? I don't care what your internal name for the newsletter is. I just want to stop seeing it in my inbox.

I don't play the guitar very well at all. I'll sometimes say that I play it better than average, but that's a claim that can only be justified by pointing out that the vast majority of people don't play guitar at all so anyone who knows two or three chords is already well above average.

Some Perl projects show you the faces of their community: you can see the people behind WebGUI or profiles of the current Bugzilla developers. Foswiki also has a page for currently active developers or you can see the Bricolage team or the Dreamwidth people. Padre has a page for developers and an additional one for translators.

Do you know about similar pages of other Perl projects?

Based on the comments:

I am not sure why I have forgotten to add search.CPAN.org where you can see the faces of many authors. There is also the who page of the London Perl Mongers.

We're all, of course, very happy about the results of the House of Commons Science and Technology committee's evidence check on homeopathy. But it's important to realise exactly what has happened. This is a House of Commons committee which has produced a list of recommendations. The government is under no obligation at all to take any notice of those recommendations. Unfortunately, Richard Wiseman's tweet, "yipppeeee it's official, NHS will no longer give people smarties", is likely to be somewhat premature.

So that's why I've set up a petition on the number 10 web site. The petition says:

We the undersigned petition the Prime Minister to Implement the recommendations of the House Commons Science and Technology committee evidence check on Homeopathy.

The House Commons Science and Technology committee has recently undertaken an evidence check on the usefulness of homeopathy and has now published its report.

The conclusions are unequivocal. They say "To maintain patient trust, choice and safety, the Government should not endorse the use of placebo treatments, including homeopathy. Homeopathy should not be funded on the NHS and the MHRA should stop licensing homeopathic products."

The government should implement these recommendations as soon as possible.

If we can get enough people to sign this petition I hope we can send a message to the government letting them know that we support the committee's findings and don't want the NHS's money wasted on nonsense like homeopathy.

Of course, this close to an election, the government is likely to be very wary of making any kind of a statement that might lose them support amongst the woo-mongers. We need to persuade them that skeptical (and rational) voters outnumber the idiots. At the very least, we should be able to get more signatures than this ridiculous petition.

So please sign the petition. And please pass the details on to anyone else who might be interested. The battle has not been won yet.

Don't have time to go into the detail that it deserves, but the House of Commons science and technology committee has published the results of its evidence check on homeopathy. The results won't, of course, come as any surprise to anyone who has been following the debate. But I have to admit to be impressed by the lack of ambiguity in their conclusions. This is paragraph 157:

By providing homeopathy on the NHS and allowing MHRA licensing of products which subsequently appear on pharmacy shelves, the Government runs the risk of endorsing homeopathy as an efficacious system of medicine. To maintain patient trust, choice and safety, the Government should not endorse the use of placebo treatments, including homeopathy. Homeopathy should not be funded on the NHS and the MHRA should stop licensing homeopathic products.

Absolutely no equivocation there.

So what's the next step? When to the homeopathic "hospitals" get closed down? When does the NHS get that money back for real medicine?

Update: The Woo-mongers in the House of Commons don't plan to take this laying down. They've proposed an Early Day Motion criticising the committee's report. Of course, only MPs with no grasp of science will be signing it. If your MP is on this list, then I suggest a strongly worded email might be in order.
