Just chilling on the House if Lords terrace. No biggie.


If I didn't spend so much time on my status report, my status report might just become a progress report.


Hmm... Might be 25 years since I saw Kraftwerk. It was The Mix tour. And that was released in 1991.


Ooh. Kraftwerk at the Albert Hall 21/22 June next year. It's been over 20 years since I saw them. Very tempting.

During the week, Barbie sent out the results from the feedback survey that he ran after YAPC Europe. The general results will be published later, but all of the speakers will have received an email containing the feedback from their talks. That feedback is private, but I’m happy to share mine with the world.

The feedback survey takes the form of five questions. People are asked to answer these questions with a rating from 1 to 10. The questions are:

There is also an opportunity for people to write in more detailed comments if they want.

I gave two talks at the conference. A lightning talk called “Medium Perl” which introduced the idea of the Cultured Perl blog and a longer talk called “Error(s) Free Programming” which talked about Damian Conway’s module Lingua::EN::Inflexion.

Eight people gave feedback on “Medium Perl”.

Qu 1 2 3 4 5 6 7 8 9 10 Avg

Q5 2 1 1 4 8.875

What aspects of the tutorial or presentation worked really well?

How could the tutorial or presentation be improved?

I’m not really sure how I’m supposed to make Medium change their fonts. I suppose I could suggest that they make other fonts available as an option. But then, so could the person who made that comment.

Four people gave feedback on “Error(s) Free Programming”.

What aspects of the tutorial or presentation worked really well?

How could the tutorial or presentation be improved?

I can only suggest that the last people reads the talk description, not just the title in future.

I also got feedback about the “Modern Web Programming with Perl and Dancer” course that I ran before the conference. The feedback here is in a slightly different format as it’s a form that I made up myself. I got feedback from 11 people.

1 2 3 4 5 6 7 8 9 10 Avg
On a scale of 1 to 10, how do you rate your Perl ability?

On a scale of 1 to 10, how useful did you find the course?
2 1 6 1 1  7.45
On a scale of 1 to 10, how much did you enjoy the course?

On a scale of 1 to 10, how do you rate the instructor’s knowledge of the subject?
2 1 6 2  8.72
On a scale of 1 to 10, how well did the instructor teach the subject matter?
1 2 2 4 2  8.36
On a scale of 1 to 10, please rate the amount of material covered
1 1 3 1 1 2 2  6.27

That last question is always tricky. The form is clear that if you think it was just right, to score 5. But I always get some people choosing 10 and I think I’d know if people thought I was covering stuff far too quickly. That 1 is a bit of a worry though.

So, all in all, not bad scores. And generally people saying nice things. Which is always nice to see.

Now I need to start thinking about the London Perl Workshop.

YAPC Europe 2016

I’ve been back from Cluj-Napoca for almost a week, so I should really write down what I remember about YAPC Europe before it’s all forgotten.

Day -1

I arrived in Cluj-Napoca on Sunday evening and got to my hotel quickly. There was just time for a quick meal before bed.

Monday was the day that I was going to get to grips with the city. After meeting a few Perl Mongers at breakfast, my wife and I set off to explore. My first target was to find Cluj Hub, the venue where I was running a training course the following day. That was simple and took less than fifteen minutes. We then explored both the Orthodox and Catholic cathedrals before settling into a bar on the main square called “Guevara” for a coffee. After that we decided that we needed to pick up some supplies and whilst on that hunt we bumped into Max Maischein who recommended a visit to the botanical gardens.

On returning to the hotel with our supplies, we met Curtis Poe and invited him to join us for lunch. Wandering at random we found a really good restaurant called Livada and enjoyed a very pleasant meal.

After lunch we spent a very enjoyable couple of hours in the botanical gardens and only just failed to get back to the hotel before it really started raining. That evening we ate in restaurant really close to the hotel called the Crying Monkey (but in Romanian).

Day 0

Tuesday was my “Modern Web Development with Perl and Dancer” training course. This was by far the most successful training course that I’ve ever run at a YAPC. I’ll write more about it when I get the feedback results, but I think that the attendees enjoyed it. I know I had great fun giving it. Cluj Hub was a great venue and Andra Gligor and her small team looked after us all really well.

That evening, the traditional pre-conference meet-up was held on the roof of Evozon’s offices. As always, it was lovely to catch-up with old friends that I only get to see once or twice a year.

Day 1

On Wednesday, I set off in plenty of time to find the venue. It turned out that our hotel was really well located for both sight-seeing and the conference and I got there in ten minutes or so. The registration queues seemed shorter than usual and before long I had my name-tag and bag of conference swag.

As always, there were far too many good talks and it was impossible to see everything. I’ll just talk about the talks that I saw. Everything was videoed, so it will all be online soon.

The day began with Amalia welcoming us to the conference. Then the YAPC Europe Foundation announced that next year’s conference will be in Amsterdam. This is the first time that the conference has returned to a previous city (the second YAPC Europe was held in Amsterdam back in 2001) and I’m looking forward to going.

The first day’s keynote was from Curtis Poe. It was a wide-ranging talk covering the history and future of both Perl and the Perl community. After that I went into one of the small rooms to see H. Merijn Brand talking about his recent improvements to Perl’s CSV parser followed by Alex Muntada on how the Debian project packages CPAN modules. I then went back to the main room to see Mickey Nasriachi talking about PONAPI, which is a Perl implementation of JSONAPI.

Lunch suffered slightly from the inevitable queues, but it was worth the wait as the quality of the food (as it was throughout the conference) was very high.

After lunch I saw Lee Johnson giving some Git tips, Sawyer talking about the XS guts of Ref::Util and Jose Luis Martinez talking about PAWS (the Perl interface to Amazon Web Services). I saw Jose Luis talking about PAWS last year in Granada but really wanted to see how the project is progressing. I think this has the potential to be a great advocacy tool for Perl.

A quick coffee break and then I saw Thomas Klausner give his opinions on writing API endpoints and Tina Müller talking about App::Spec which looks like a great tool for easily writing command line applications.

Then it was was lightning talks. They were the usual combination of the useful, the banal and the ridiculous. I think the highlight for me was Curtis Poe announcing more details of his online game (which is now officially called Tau Station). This was the point at which I announced Cultured Perl – which seems to be going well so far.

That evening was the conference dinner. Which was a buffet party held in the open-air quadrangle at the centre of the Banffy Palace (Cluj’s major art museum). A great time was had by all.

Day 2

Another day, another keynote. This time it was Sawyer X with “The State of the Velociraptor” – an annual round-up of what’s going on in the Perl 5 world. This year Sawyer found a number of volunteers who all gave short talks about their part of the Perl community. This was a great idea which was only slightly marred by the fact that the projector wasn’t at all happy changing laptops – so the switches between presenters weren’t as smooth as they could have been.

After that I saw Max talking about how he uses ElasticSearch on his laptop to give himself a local search engine and Job van Achterberg talking about making web sites more accessible. This was a great talk – particularly the sections where he showed just how bad most web sites appear to screen readers.

Another queue for another great lunch. And also many interesting conversations.

After lunch I saw a former colleague, Mirela Iclodean, talking about how her company have managed to shoe-horn many modern tools and practices into their working day – while still maintaining a nasty monolithic code-base which they are slowly chipping away at. It was a great talk and it made me miss working on that project. I’m hoping that she will repeat this talk at the London Perl Workshop.

Later that afternoon, I gave my “Error(s) Free Programming” talk – in a slot where every speaker was a leader. The talk seemed to go down well, but somehow I ran considerably short.

After that I saw Albert Hilazo talk about his first few months as a Perl programmer. I found this really interesting as Albert talked in some detail about things that other language communities provide but he found hard to find for Perl. In particular, he would like to see more “war story” blog posts showing how people have solved particular problems using Perl tools.

Then it was Matt Trout celebrating ten years in the Perl community by explaining how his career was largely a series of happy accidents and that a lot of the responsibilities he has taken on were just through being in the wrong place at the wrong time – or something like that.

One talk I couldn’t miss was Andrew Yates talking about the work that his team do at the European Bioinformatics Institute. I couldn’t miss it as I was at least partly responsible for Andrew proposing the talk. I ran some training at the EBI earlier this year and during our email conversation YAPC was mentioned and Andrew asked if people might be interested in hearing about their work. I replied “hell, yes!” and sent him a link to the talk proposal web page.

And then, of course, there another ten or so lightning talks to close the day entertainingly.

Day 3

The keynote speaker on the last day was Larry Wall. His topic was “Strange Consistency”. If you’ve seen Larry speak before, you’ll know what it was like.

I followed that by watching Jason Clifford talk about how his team had written a major new toolset in Perl despite management pressure to use other technologies. The project, of course, ended up being very successful.

One of the most interesting talks was Nicholas Clark’s view of an alternative universe where Jon Orwant never threw those mugs in 2000 and the Perl 6 project was never started. The main lesson appeared to be “what goes around, comes around” and his fictional universe didn’t end up too far away from where we are now.

The afternoon had a curious combination of some time slots where I wanted to see every talk and others where I didn’t really want to see anything. So in some cases I’m eagerly awaiting the videos going online and in others I sat in the back of the room only half-concentrating while giving most of my attention to Twitter or Facebook.

I really enjoyed Sawyer talking about the things that were added in Perl 5.24 (and very carefully not talking about the things that were added in previous versions) and also Jose Luis Perez talking about what he has got out of doing the CPAN Pull Request Challenge.

The final lightning talks were as much fun as they always are. The projectors were still giving the speakers plenty of technical difficulties which led to lots of time for “lightning adverts” between the talks. I think that towards the end the differences between the two rather broke down and on the video at one point I expect you’ll hear Geoff Avery saying “I seem to have lost control of this”.

The conference ended, as it always does, with a brief presentation from the organisers of next year’s conference, a final thank-you to all of the speakers and sponsors and a standing ovation for the organisers.

This was one of the best-organised YAPCs I’ve been to for a very long time. And Cluj-Napoca is a city I would never have considered visiting if it wasn’t for the Perl community there. And already I’m considering a return visit. I had a lovely time in the city and returned to London completely recharged and reinvigorated.

See you all in Amsterdam next year.

Yesterday at YAPC Europe I gave a talk called “Error(s) Free Programming”. The slides are below, but it might make more sense once the video is online.

Error(s) Free Programming from Dave Cross

The talk is about Damian Conway’s module Lingua::EN::Inflexion and how it makes programmers’ lives easier. As part of the talk, I invented a logo for the fictional DamianWare brand. DamianWare is, of course, a brand that specialises in using deep Perl magic in order to produce tools that help Perl programmers be lazier.

It was just a joke. A throwaway visual to make a point in the presentation. But after the talk Mallory approached me and suggested that the logo would look great on a t-shirt which was sold to benefit The Perl Foundation. I couldn’t really argue with that.

And, having emailed him overnight, it turns out that Damian agrees it’s a good idea too.

So the shirts (and a couple of other things) are now available on Spreadshirt (currently the UK version, I’ll try to make them more widely available as soon as possible).

There’s an easier to remember URL at

Any profit that I make (and I think it’s about 20% of the sale price) will be donated to TPF as soon as I receive it.

Cultured Perl

Back in about 2008, I set up a group blog called “Cultured Perl”. The idea was to have a blog that concentrated on the Perl community rather than the technical aspects that most Perl bloggers write about most of the time. It didn’t last very long though and after a few posts it quietly died. But the name “Cultured Perl” still appeals to my love of bad puns and I knew I would reuse it at some point.

At YAPC Europe 2010 in Pisa, I gave a lightning talk called Perl Vogue. It talked about the way the Perl modules come into fashion and often go out of fashion again very quickly. I suggested an online Perl magazine which would tell people which modules were fashionable each month. It was a joke, of course (not least because Vogue are famously defensive of their brand.

Over the last many years people have suggested that the Perl community needs to get “out of the echo chamber” and talk to people who aren’t part of the community. For example, instead of posting and answering Perl questions on a Perl-specific web site like Perl Monks, it’s better to do it on a general programming site like Stack Overflow.

Hold those three thoughts. “Cultured Perl”, online Perl magazine, getting out of the echo chamber.

Medium is a very popular blogging site. Many people have moved their blogging there and it’s a great community for writing, sharing and recommending long-form writing. I get a “recommended reading” email from Medium every day and it always contains links to several interesting articles.

Medium has two other features that interest me. Firstly, you can tag posts. So if you write a post about web development using Perl and tag it with “web dev” then it will be seen by anyone who is following the web dev tag. That’s breaking out of the echo chamber.

Secondly, Medium has “publications”. That is, you can bring a set of articles together under your own banner. Publication owners can style their front page in various ways to differentiate it from Medium’s default styling. Readers can subscribe to publications and they will then be notified of every article published in that publication. That’s an online magazine.

So I’ve set up a publication on Medium (called “Cultured Perl” – to complete the set of three ideas). My plan is to publish (or republish) top quality Perl articles so we slowly build a brand outside of the echo chamber where people know they can find all that is best in Perl writing.

If you write about Perl, please consider signing up to Medium, becoming a contributor to Cultured Perl and submitting your articles for publication. I’ll publish the best ones (and, hopefully, work with authors to improve the others so they are good enough to publish).

I’m happy to republish stuff from your other blogs. I’m not suggesting that we suddenly move all Perl blogging to Medium. For example, whenever I publish something on Perl Hacks, the post gets mirrored to a Perl Hacks publication that I set up on Medium earlier this year. There’s a WordPress to Medium plugin that does that automatically for me. There may well be similar tools for other blogging platforms (if you can’t find one for your blog – then Medium has an API so you could  write one).

If you are a reader, then please consider subscribing to Cultured Perl. And please recommend (by clicking on the heart symbol) any articles that you enjoy. The more recommendations that an article gets, the more likely it becomes that Medium will recommend it to other readers.

I have no idea how this will go, but over the next few months I hope to start by publishing four or five articles every week. Perhaps you could start by submitting articles about what a great time you had at YAPC Europe.

Oh, and here are the slides from the lightning talk I used to announce this project at YAPC Europe in Cluj-Napoca, Romania yesterday.

Intended Audience

I thought I’d pretty much finished blogging about my upcoming Modern Web Development with Perl and Dancer training course. But a couple of days ago I saw a tweet that reminded me about an aspect that I’d completely forgotten.

And he’s right, of course. I haven’t mentioned that at all. Let’s put that right.

As it happens, yesterday I pretty much finished writing the slides for the course. So that means that I know what I’ll be covering and, therefore, what the attendees will need to know.

What You’ll Need To Know

To start with, I need to make it clear that this is not a “beginning Perl” course. There’s a lot of new topics to cover and if Perl itself was on the list then it would need to be a two or three day course.

So you’ll need to know Perl. But to what level?

If you’ve read Intermediate Perl then you’ll be fine. That means you’ll need to understand how to use modules, packages and references. Probably the most advanced Perl concept we’ll need is subroutine references. But, to be honest, if you’re not completely comfortable with them, that won’t be a problem.

You’ll need to know a bit about how web pages are made – so a little bit of HTML and CSS. We’ll be using Bootstrap to deal with most of our CSS, so you won’t need to do anything at all complicated with CSS. If you understand the difference between a class and an id in CSS terms then you’ll be fine.

We’ll be using quite a lot of Javascript – specifically jQuery with Mustache. I’m no Javascript expert, so it’s likely that many of the people in the class will know more than me. If you’ve never used jQuery, then I recommend that you spend a couple of hours looking into it before coming to the class. You don’t need to know anything about Mustache before the course.

There will be a database at the back-end of the app. I’ll be running MySQL (actually, probably MariaDB), but any of the popular database systems will work – just as long as Perl’s DBI supports it. I’ll supply SQL to set up the database and insert some test data and we’ll be using DBIx::Class which will remove the need to know any SQL. But it would be good if you were familiar with whatever database system you’re using – to the extent that you can run queries against your local database.

What You’ll Need to Bring

You’ll need a laptop. I’m assuming that we’ll have access to WiFi at the training venue, but it would be great if you could install as much as possible of the required software before the day – just so we save a bit of time.

My laptop runs Windows 10, but I do all of my development in a virtual machine running Fedora 24. I’m happy for you to work in Windows or OSX, but the level of support I can provide for people not running Linux will be limited.

You’ll need Perl installed. Linux and OSX will already have a version of Perl installed. For Windows users, I recommend Strawberry Perl. Get the most recent version of Perl that you can install. The current version is 5.24. I think my laptop has 5.22. Anything  earlier than 5.10 is unlikely to be particularly useful.

You’ll need some CPAN modules installed. These are all pretty common modules:

You’ll need a database server installed on your laptop. As I mentioned above, any of the popular database engines will work – but I’ll be using MariaDB. Make sure that you know how to start the database server and connect to it using a command line program.

You’ll need a Git client so that you can clone the Git repository that contains the source code for the course. You’ll want to ensure the the repository is cloned to your laptop before turning up to the course. You might even want to glance through some of the code to get a head-start on the rest of the attendees.

You can find the course code at

The CSS and Javascript libraries are all included in the Git repository.

I think that’s about all you need to know. Please let me know if you have any further questions.

I’ve been really pleased with the reaction to this course. We already have a large number of people signed up. So many, in fact, that I need to start thinking about the number of people I have room for. I think we can get another five (perhaps ten) people in. So if you’re thinking of signing up, please do it soon to avoid disappointment (trainers say stuff like this for every course – but this time it’s really true).

Hope to see some of you in Cluj-Napoca.

I was awake soon after 5:30 yesterday morning. As I got to my computer, the EU referendum results weren’t confirmed, but it was looking certain that the country had voted (narrowly, but decisively) to leave the European Union. My thoughts during the day are nicely summed up by my tweets and retweets.

My initial reaction was anger.

(Hmm… the downside of rolling news coverage – that story has changed dramatically since I first linked to it.)

A few minutes later I was slightly more coherent (and almost philosophical)

Then the reality of the situation started to sink in

I tried to be positive

I was being sarcastic, of course. We’ll return to this subject later on.

I started to see life imitating art in a quite frightening way.

(And, yes, I know I should replace that picture with one of Boris Johnson)

Nigel Farage is (and, apparently, always has been) a despicable man. So it should have come as no surprise that his victory speech was insulting and divisive.

I don’t mind not being considered ordinary, but I’m certain I’m real and I like to think I’m decent. Tom Coates inverted Farage’s phrase nicely.

When Cameron resigned, I immediately became worried about the fall-out.

Really, if your best option is a man who stuck his penis into a pig’s mouth, then it must be clear that you’re in trouble.

Then I checked the stock market and realised that many of the Brexit supporters may have shot themselves in the foot.

A story in the FT illustrated the fall nicely (“nicely” isn’t really the right word!)

The markets bounced back a bit later in the day – but it was one of the most volatile days of trading in history.

Fox News can, of course, always be relied on to get important facts wrong.

Then I started to see data on the demographics of the voting – where it became obvious that it was mainly the older generations who were voting against the EU

Can I just point out that it’s #NotAllBabyBoomers :-/

Remember the £350m a week that was going to be diverted to the NHS. Turns out that was a lie.

It was a lie on many fronts.

It was a lie that the Leave campaign were called out on many times, but they refused to retract it.

To be fair to Farage (and that’s not a phrase I ever expected to write) he wasn’t part of the official Leave campaign, so he wasn’t the right person to ask about this. But someone should certainly take Johnson or Gove to task over it.

Going back to the baby-boomers, I retweeted a friend’s innocent question

Then it started to look like Cameron might not be the only party leader to go in the fallout from the referendum

Incidentally, has anyone seen any evidence of the Lib Dems in this campaign? A couple of days ago I saw footage of Tim Farron in a crowd somewhere. Took me a few seconds to remember who he was; and then another minute or so to remember that he was the leader of the Lib Dems.

Euro-myths have always really annoyed me

More bad news from the City

I should point out that Morgan Stanley have denied the story. I guess time will tell who is telling the truth here.

By mid-afternoon, I was working on alternative plans

A final thought struck me

I mean, they were a single-issue party. And they’ve won that battle. Surely, there’s no need for the party to exist any longer. They can’t surely expect people to vote for them now (although, UK voters are a very strange bunch). If they closed down, they could all go back to the Tories and Farage and Carswell could get places in the new Johnson/Gove cabinet.

Oh, now I’m really depressed.

Ten Years?

It’s been some considerable time since I wrote anything about Nadine Dorries. I still keep an eye on what she’s up to, but most of the time it’s just the same old nonsense and it’s not worth writing about.

But I was interested to read her recent blog post explaining why she had given up Twitter (again). Of course, she uses it to rehash many of her old claims of stalking and the like, but what I found really interesting was when she said:

After almost ten years on Twitter (so long I can’t remember) and with 28,000 followers, I have made my own modest exit.

Because that “almost ten years” didn’t fit my recollections. Twitter has just had its tenth anniversary. As I wrote recently, almost no-one has been on Twitter for ten years – certainly not any British MPs.

It’s simple enough to use one of the many “how long have I been on Twitter?” sites to work out when her current @NadineDorriesMP account joined Twitter. It seems to be January 2012.

But that’s not the full story. She has joined and left Twitter a few times. Let’s see what we can find out.

Firstly, here’s a blog post from May 2009 where she doesn’t seem to be planning to join Twitter any time soon.

Anyway, safe to say, I shan’t be joining the legions of twitters any day soon.

It’s several months later, in September 2009, when she announces that she has joined Twitter. So that “ten years” is more like six and a half.

I’m pretty sure that first account was also called @NadineDorriesMP. At some point over the next couple of years, she closed that account (I’ll dig through her blog later to see if I can find any evidence to date that) and some time later she returned with a new account called @Nadine_MP. I know that because in May 2011 she gave up that second account and forgot to remove the Twitter widget from her web site. Then someone else took over the now-abandoned username and used it to deface her site. And then, as we saw above, she rejoined in January 2012.

So I think the list of Nadine’s Twitter accounts goes like this:

That last account is still registered. She just chooses not to use it any more. If past behaviour is anything to go by, she’ll be back at some point.

Anyway, here’s another good example of why you can’t trust anything that Dorries says. Even on a simple fact like how long she has been using Twitter, she just pulls numbers out of the air. She makes stuff up to suit her and she’s been doing it for years.

Twitter’s Early Adopters

You’ll be seeing that tweet a lot over the next few days. It’s the first ever public tweet that was posted to the service we now know as Twitter. And it was sent ten years ago by Jack Dorsey, one of Twitter’s founders.

Today, Twitter has over a hundred million users, who send 340 million tweets a day (those numbers are almost certainly out of date already) but I thought it would be interesting to look back and look at Twitter’s earliest users.

Every Twitter user has a user ID. That’s an integer which uniquely identifies them to the system. This is a simple incrementing counter[1]. You can use a site like MyTwitterID to get anyone’s ID given their Twitter username. It’s worth noting that you can change your username, but your ID is fixed. When I registered a new account last week, I got an ID that was eighteen digits long. But back in 2006, IDs were far shorter. Jack’s ID, for example, is 12. That’s the lowest currently active ID on the system. I assume that the earlier numbers were used for test accounts.

Using the Twitter API you can write a program that will give you details of a user from their ID. Yesterday I wrote a simple program to get the details of the first 100,000 Twitter users (the code is available on Github). The results from running the program are online. That’s a list of all of the currently active Twitter users with an ID less than 100,000.

The first thing you’ll notice is that there are far fewer than you might expect. The API only returns details on currently active users. So anyone who has closed their account won’t be listed. I expected that perhaps 20-25% of accounts might fall into that category, but it was much higher than that.

There are 12,435 users in the file. That means that 87,500 of the first 100,000 Twitter accounts are no longer active. That was such a surprise to me that I assumed there was a bug in my program. But I can’t find one. It really looks like almost 90% of the early Twitter users are no longer using the service.

The dates that the account were created range from Jack‘s on 21st March 2006 to Jeremy Hulette (ID 99983 – the closest we have to 100,000) exactly nine months later on 21st December 2006.  I guess you could get a good visualisation of Twitter’s early growth by plotting ID against creation date – but I’ll leave that to someone else.

My file also contains location. But it’s important to note that I’m getting the location that is currently associated with that account – not the original location (I wonder if Twitter still have that information). I know a large number of people who were in London when they joined Twitter by who are now in San Francisco, so any conclusions you draw from the location field are necessarily sketchy. But bearing that in mind, here are some “firsts”.

That last one seems a little high to me. I might have missed someone earlier who didn’t put “UK” in their location.

So who’s on the list? Is there anyone famous? Not that I’ve seen yet. Oh, there are well-known geeks on the list. But no-one you’d describe as a celebrity. No musicians, no actors, no politicians, no footballers or athletes. I may have missed someone – please let me know if you spot anyone.

Oh, and I’m on the list. I’m at number 14753. I signed up (as @davorg) at 11:30 on Wednesday 22nd November 2006. I suspect I’m one of the first thousand or so Brits on the list – but it’s hard to be sure of that.

Anyway, happy birthday to Twitter. I hope that someone finds this data interesting. Let me know what you find.

My Family in 1939

Here in the UK, a census has been taken almost every ten years since 1841. There were a few censuses before that, but before 1841 they only counted people – they didn’t include lists of names.

These census records are released 100 years after the date of the census and this data is of great interest to genealogists. The most recent census that we have access to is from 1911 and the one from 1921 will be released at the start of 2022.

But occasionally, other records emerge that are almost as useful as a census. For example, in September 1939, on the eve of the Second World War, the British government took a national register which was used to issue identity cards to everyone.

Last November, FindMyPast made the contents of this register available to everyone. Initially I didn’t look at it as I have a FindMyPast subscription and I was annoyed that this didn’t cover the new records. I assumed that eventually the new data would be rolled into my existing subscription, so I decided to wait.

I didn’t have to wait very long. Yesterday I got access to the records. So I settled down last night to find out what I could about my ancestors in 1939. As it turned out, it didn’t take long. There were only ten of them and they were split across four households.


This is most of my father’s family. You can see his parents, James and Ivy Cross. They are living with Ivy’s parents George and Lily Clarke. George worked for Greene King all of his life (for over sixty years) and this is the last job he did for them – running an off-licence in Holland-on-Sea. James and Ivy lived in the same building until James died in 1970. I remember spending a lot of time there when I was a child. I even have vague memories of George who died when I was three or four.

My father was born three months after this register was taken – in January 1940 – so it’s interesting to note that Ivy is, at this time, six months pregnant.


Just down the road are the rest of my father’s family – James’ parents Albert and Lily Cross living with their daughter (my great-aunt) Grace. Albert’s father (another James) was the lifeboatman who I have written about before.


Looking a bit further afield, we find most of my mother’s family living in Thorpe-le-Soken. You’ll see my great-grandparents, Robert and Agnes Sowman, along with three closed records. Records are closed if the people in them are born less than 100 years ago and aren’t known to have died. The first two closed records here are my grandmother, Cecilia, and her sister Margaret. Both of these woman are no longer alive, so I should be able to get FindMyPast to open these records by sending them copies of their death certificates. The third closed record will be for Constance, the third daughter in the family.


And finally, here’s the final part of my family. Maud Turpin, living alone in Maldon. Maud is Agnes Sowman’s mother. Actually, this record showed me the only piece of information that I didn’t already know. Previously, I wasn’t sure when Maud’s husband Alfred died. He was still alive in the 1911 census and this record gives me strong evidence that he died before 1939. I think I’ve found a good candidate for his death record in 1931.

So that’s a pretty good summary of what you’ll find in the 1939 register. It’s a good substitute for a census (particularly as there was no census in 1941 – as the country was too busy fighting a war) and it’s nice that it’s not covered by census privacy laws, so it has been released to the public about 25 years sooner than you might expect. But, certainly in my case, I already had a lot of knowledge about my family in this period so I didn’t learn very much that was new. If I had paid the £7 per household that FindMyPast had initially asked for, I think I would have been very disappointed.

I should point out that You don’t just get this information. Each results page gives a map (actually, a selection of maps) showing where your ancestors lived. This is a nice touch. There are also random newspaper cuttings and photos from the locality. You might find these interesting – I really didn’t.

Has anyone else used these records yet? Have you found anything interesting?

p.s. And yes, if you’re paying close attention, you’ll notice that there’s one grandparent missing from my list above. Ask me about that in the pub one day.

2015 in Gigs

As has become traditional round these parts, it’s time for my annual review of the gigs I saw last year.

I saw 48 gigs in 2015. That’s up on 2014’s 45, but still short of my all time high of 60 in 2013. I saw Chvrches, Stealing Sheep and Paper Aeroplanes twice. I was supposed to see a couple of other artists twice, but Natalie Prass cancelled the second show and I couldn’t get to the second Soak show as I was ill.

As always, there were some disappointments. Renaissance really weren’t very good (I waited to hear “Northern Lights” and then buggered off) and Elbow weren’t as good as I’d seen them before. But the biggest disappointment this year has to be Bob Dylan. He was terrible. I left at the interval.

About half-way through the year, I stopped writing reviews on my gig site. I’ve put up posts with just the data about the shows and I hope to back-fill some of the reviews at some point, but I can’t see it happening soon. Hopefully I’ll keep the site more up to date this year.

So here (in chronological order) are my favourite gigs of the year:

Gigs that fell just outside of the top ten included Julian Cope, Suzanne Vega, Paper Aeroplanes and Smoke Fairies. Oh, and the Indie Daze Festival was great too.

I already have tickets for a dozen shows in 2016. I’m particularly looking forward to ELO in April and seeing the Cure for the first time for far too many years in December.
