[Bloganuary] Fun Five

This post is part of my attempt at Bloganuary 2024. Today’s prompt is:

List five things you do for fun.

This feels disappointingly like the prompt from day 2, but I’m gonna pivot it by letting my answer from three weeks ago only cover one of the five points:

Code
Magic
Piano
Play
Learn

Let’s take a look at each of those, briefly.

Code

Code is poetry. Code is fun. Code is a many-splendoured thing.

This is not what real coding looks like. This is what real coding looks like.

When I’m not coding for work or coding as a volunteer, I’m often caught coding for fun. Sometimes I write WordPress-ey things. Sometimes I write other random things. I tend to open-source almost everything I write, most of it via my GitHub account.

Magic

Now I don’t work in the city centre nor have easy access to other magicians, I don’t perform as much magic as I used to. But I still try to keep my hand in and occasionally try new things; I enjoy practicing sleights when I’m doing work-related things that don’t require my hands (meetings, code reviews, waiting for the damn unit tests to run…), a tip I learned from fellow magician Andy.

My favourite go-to trick with an untampered deck of cards is my variant of the Ambitious Classic; here’s a bit from the middle of the trick from the last time I performed it in a video meeting.

You’ll usually find a few decks of cards on my desk at any given time, mostly Bikes.¹

Piano

I started teaching myself piano during the Covid lockdowns as a distraction from not being able to go anywhere (apparently I’m not the only one), and as an effort to do more of what I’m bad at.² Since then, I’ve folded about ten minutes of piano-playing³, give or take, into my routine virtually every day.

This is what piano playing looks like. But perhaps only barely.

I fully expect that I’ll never be as accomplished at it as, say, the average 8-year-old on YouTube, but that’s not what it’s about. If I take a break from programming, or meetings, or childcare, or anything, I can feel that playing music exercises a totally different part of my mind. I’d heard musicians talk about such an experience before, but I’d assumed that it was hyperbole… but from my perspective, they’re right: practicing an instrument genuinely does feel like using a part of your brain than you use for anything else, which I love!

Play

I wrote a whole other Bloganuary post on the ways in which I integrate “play” into my life, so I’ll point you at that rather than rehash anything.

A lot of my RPG-gaming takes place online, via virtual tabletops, and is perhaps the most obvious “playtime” play activities I routinely engage in.

At the weekend I dusted off Vox Populi, my favourite mod for Civilization V, my favourite⁴ entry in the Civilization series, which in turn is one of my favourite video game series⁵. I don’t get as much time for videogaming as I might like, but that’s probably for the best because a couple of hours disappeared on Sunday evening before I even blinked! It’s addictive stuff.

Learn

As I mentioned back on day 3 of bloganuary, I’m a lifelong learner. But even when I’m not learning in an academic setting, I’m doubtless learning something. I tend to alternate between fiction and non-fiction books on my bedside table. I often get lost on deep-dives through the depths of the Web after a Wikipedia article makes me ask “wait, really?” And just sometimes, I set out to learn some kind of new skill.

It’s not always wacky and off-the-wall things like basic blacksmithing that I learn. Sometimes it’s normal, practical activities like baking bread or… umm… Argentine tango?

In short: with such a variety of fun things lined-up, I rarely get the opportunity to be bored⁶!

¹ I like the feel of Bicycle cards and the way they fan. Plus: the white border – which is actually a security measure on playing cards designed to make bottom-dealing more-obvious and thus make it harder for people to cheat at e.g. poker – can actually be turned to work for the magician when doing certain sleights, including one seen in the mini-video above…

² I’m not strictly bad at it, it’s just that I had essential no music tuition or instrument experience whatsoever – I didn’t even have a recorder at primary school! – and so I was starting at square zero.

³ Occasionally I’ll learn a bit of a piece of music, but mostly I’m trying to improve my ability to improvise because that scratches an itch in a part of my brain in a way that I find most-interesting!

⁴ Games in the series I’ve extensively played include: Civilization, CivNet, Civilization II (also Test of Time), Alpha Centauri (a game so good I paid for it three times, despite having previously pirated it), Civilization III, Civilization IV, Civilization V, Beyond Earth (such a disappointment compared to SMAC) and Civilization VI, plus all their expansions except for the very latest one for VI. Also spinoffs/clones FreeCiv, C-Evo, and both Call to Power games. Oh, and at least two of the board games. And that’s just the ones I’ve played enough to talk in detail about: I’m not including things like Revolution which I played an hour of and hated so much I shan’t touch it again, nor either version of Colonization which I’m treating separately…

⁵ Way back in 2007 I identified Civilization as the top of the top 10 videogames that stole my life, and frankly that’s still true.

⁶ At least, not since the kids grew out of Paw Patrol so I don’t have to sit with them and watch it any more!

Debugging Mysteries

This article is a repost promoting content originally published elsewhere. See more things Dan's reposted.

Just wanted to share with you something I found ages ago but only just got around to mentioning – Julia Evans‘ (of Wizard Zines fame) Debugging Mysteries:

There are five mysteries here right now:

The Case of the Slow Websites
The Case of the Connection Timeout
The Case of the DNS Update that Didn’t Work
The Case of the 50ms Request
The Case of the Failed Docker Connection

Julia Evans

Each mystery is a Twine-powered “choose your own adventure” game in which you must diagnose the kind of issue that a software developer might, for real. I think these are potentially excellent tools for beginner programmers, not just because they provide some information about the topic of each, but because they encourage cultivating a mindset of the kind of thinking that’s required to get to the bottom of gnarly problems.

Better yet, she’s open-sourced the entire thing (and I was excited to see she wrote in Twee, which is very dear to my heart).

Do What You’re Bad At [Video]

This video accompanies a blog post of the same title. The content is basically the same – if you prefer videos, watch this video. If you prefer blog posts, go read the blog post. If you’re a superfan, try both and spot the differences. You weirdo.

Also available on YouTube or on Facebook.

Do What You’re Bad At

This blog post is also available as a video. Would you prefer to watch/listen to me tell you about how I’ve learned to enjoy doing what I’m bad at?

There are a great number of things that I’m bad at. One thing I’m bad at (but that I’m trying to get better at) is being more-accepting of the fact that there are things that I am bad at.

I’m pretty bad in a pub quiz. I’m bad at operating my pizza oven without destroying cookware. I’m especially bad at learning languages. I’m appallingly bad at surfing. Every time my work periodically leans in that direction I remember how bad I am at React. And I’ve repeatedly shown that I’m bad at keeping on top of blogging, to the extent that I’ve periodically declared bankruptcy on my drafts folder.

So yeah, pretty bad at things.

But hang on: that assessment isn’t entirely true.

Being Bad

As a young kid, I was a smart cookie. I benefited from being an only child and getting lots of attention from a pair of clever parents, but I was also pretty bright and a quick learner with an interest in just about anything I tried. This made me appear naturally talented at a great many things, and – pushed-on by the praise of teachers, peers, and others – I discovered that I could “coast” pretty easily.

But a flair for things will only carry you so far, and a problem with not having to work hard at your education means that you don’t learn how to learn. I got bitten by this when I was in higher education, when I found that I actually had to work at getting new information to stick in my head (of course, being older makes learning harder too, as became especially obvious to me during my most-recent qualification)!

A side-effect of these formative experiences is that I grew into an adult who strongly differentiated between two distinct classes of activities:

Things I was good at, either because of talent or because I’d thoroughly studied them already. I experienced people’s admiration and respect when I practised these things, and it took little effort to stay “on top” of these fields, and
Things I was bad at, because I didn’t have a natural aptitude and hadn’t yet put the time in to learning them. We don’t often give adults external reinforcement for “trying hard”, and I’d become somewhat addicted to being seen as awesome… so I shied away from things I was “bad at”.

The net result: I missed out on opportunities to learn new things, simply because I didn’t want to be seen as going through the “amateur” phase. In hindsight, that’s really disappointing! And this “I’m bad at (new) things” attitude definitely fed into the imposter syndrome I felt when I first started at Automattic.

Being Better

Leaving the Bodleian after 8½ years might have helped stimulate a change in me. I’d carved out a role for myself defined by the fields I knew best; advancing my career would require that I could learn new things. But beyond that, I benefited from my new employer whose “creed culture” strongly promotes continuous learning (I’ve vlogged about this before), and from my coach who’s been great at encouraging me towards a growth mindset.

But perhaps the biggest stimulus to remind me to keep actively learning, even (especially?) when it’s hard, might have been the pandemic. Going slightly crazy with cabin fever during the second lockdown, I decided to try and teach myself how to play the piano. Turns out I wasn’t alone, as I’ve mentioned before: the pandemic did strange things to us all.

I have no real experience of music; I didn’t even get to play recorder in primary school. And I’ve certainly got no talent for it (I can hear well enough to tell how awful my singing is, but that’s more a curse than a blessing). Also, every single beginners’ book and video course I looked at starts from the assumption that you’re going to want to “feel” your way into it, and that just didn’t sit well with the way my brain works.

Animation showing Dan, wearing a black t-shirt and tracksuit bottoms, playing an upright piano. — 90% of what I do in front of a piano might be described as “Dan Mucks About (in B Minor)”, but that’s fine by me.

I wanted a theoretical background before I even sat down at a keyboard, so I took a free online course in music theory. Then I started working through a “beginners’ piano” book we got for the kids. Then I graduated to “first 50 Disney songs”, because I know how virtually all of them sound well enough that I’d be able to hear where I was going wrong. Since then, I’ve started gradually making my way through a transcription of Einaudi’s Islands. Feeling like I’d got a good handle on what I was supposed to be doing, I then took inspiration from a book JTA gave me and started trying to improvise.

Most days, I get no more than about 10 minutes on the piano. But little by little, day by day, that’s enough to learn. Nowadays even my inner ~~critic~~ perfectionist can tolerate hearing myself play. And while I know that I’ll probably never be as good as, say, the average 8-year-old on YouTube, I’m content in my limited capacity.

Three books on a blue-and-white tablecloth: John Thompson's Easiest Piano Course (Part One), First 50 Disney Songs, and Essential Einaudi - Islands. Beneath them sits a simplified diagram showing the circle of fifths. — Let’s start at the very beginning. (A very good place to start.)

If I’m trying to cultivate my wonder syndrome, I need to stay alert for “things I’m bad at” that I could conceivably be better at if I were just brave enough to try to learn. I’m now proudly an “embarrassingly amateur” pianist, which I’m at-long-last growing to see as better than a being non-pianist.

Off the back of that experience, I’m going to try to spend more time doing things that I’m bad at. And I’d encourage you to do the same.

Dissertation Hand-In Déjà Vu

I last handed in a dissertation almost 16 years ago; that one marked the cumulation of my academic work at Aberystwyth University, then the “University of Wales, Aberystwyth”. Since then I’ve studied programming, pentesting and psychology (the P-subject Triathalon?)… before returning to university to undertake a masters degree in information security and forensics.

Today, I handed in that dissertation. Thanks to digital hand-ins, I’m able to “hand it in” and then change my mind, make changes, and hand-in a replacement version right up until the deadline on Wednesday (I’m already on my second version!), so I’ve still got a few evenings left for last-minute proofreads and tweaks. That said, I’m mostly happy with where it is right now.

Project management graph for my dissertation — I found it motivating to maintain a graph of my dissertation’s “outstanding tasks” where I would see it every day. Also, as it started to get hairy, my word limit.

Writing a dissertation was harder this time around. Things that made it harder included:

Writing a masters-level dissertation rather than a bachelors-level one, naturally.
Opting for a research dissertation rather than an engineering one: I had the choice, and I knew that I’d do better in engineering, but I did research anyway because I thought that the challenge would be good for me.
Being older! It’s harder to cram information into a late-thirty-something brain than into a young-twenty-something one.
Work: going through the recruitment process for and starting at Automattic ate a lot of my time, especially as I was used to working part-time at the Bodleian and I’d been turning a little of what would otherwise have been my “freelance work time” into “study time” (last time around I was working part-time for SmartData, of course).
Life: the kids, our (hopefully) upcoming house move and other commitments are pretty good at getting in the way. Ruth and JTA have been amazing at carving out blocks of time for me to study, especially these last few weekends, which may have made all the difference.

Dan's masters dissertation: "Impact of the use of Language on Adoption of Optional Multifactor Authentication" — Despite this thing being big and heavy and dense, it somehow doesn’t seem to fully represent the weight of blood, sweat and tears that went into it.

It feels like less of a bang than last time around, but still sufficient that I’ll breathe a big sigh of relief. I’ve a huge backlog of things to get on with that I’ve been putting-off until this monster gets finished, but I’m not thinking about them quite yet.

I need a moment to get my bearings again and get used to the fact that once again – and for the first time in several years – I’ll soon be not-a-student. Fun fact, I’ve spent very-slightly-more than half of my adult life as a registered student: apparently I’m a sucker it, for all that I complain… in fact, I’m already wondering what I can study next (suggestions welcome!), although I’ve promised myself that I’ll take a couple of years off before I get into anything serious.

(This is, of course, assuming I pass my masters degree, otherwise I might still be a student for a little longer while I “fix” my dissertation!)

If anybody’s curious (and I shan’t blame you if you’re not), here’s my abstract… assuming I don’t go back and change it yet again in the next couple of days (it’s still a little clunky especially in the final sentence):

Multifactor authentication (MFA), such as the use of a mobile phone in addition to a username and password when logging in to a website, is one of the strongest security enhancements an individual can add to their online accounts. Compared to alternative enhancements like refraining from the reuse of passwords it’s been shown to be easy and effective. However: MFA is optional for most consumer-facing Web services supporting MFA, and elective user adoption is well under 10%.

How can user adoption be increased? Delivering security awareness training to users has been shown to help, but the gold standard would be a mechanism to encourage uptake that can be delivered at the point at which the user first creates an account on a system. This would provide strong protection to an account for its entire life.

Using realistic account signup scenarios delivered to participants’ own computers, an experiment was performed into the use of language surrounding the invitation to adopt MFA. During the scenarios, participants were exposed to statements designed to either instil fear of hackers or to praise them for setting up an account and considering MFA. The effect on uptake rates is compared. A follow-up questionnaire asks questions to understand user security behaviours including password and MFA choices and explain their thought processes when considering each.

No significant difference is found between the use of “fear” and “praise” statements. However, secondary information revealed during the experiment and survey provides recommendations for service providers to offer MFA after, rather than at, the point of account signup, and for security educators to focus their energies on dispelling user preconceptions about the convenience, privacy implications, and necessity of MFA.

Geohashing Resurected

I keep my life pretty busy and don’t get as much “outside” as I’d like, but when I do I like to get out on an occasional geohashing expedition (like these ones). I (somewhat badly) explained geohashing in the vlog attached to my expedition 2018-08-07 51 -1, but the short version is this: an xkcd comic proposed an formula to use a stock market index to generate a pair of random coordinates, impossible to predict in advance, for each date. Those coordinates are (broadly) repeated for each degree of latitude and longitude throughout the planet, and your challenge is to get to them and discover what’s there. So it’s like geocaching, except you don’t get to find anything at the end and there’s no guarantee that the destination is even remotely accessible. I love it.

xkcd #426: Geohashing — My favourite kind of random pointlessness is summarised by this algorithm.

Most geohashers used to use a MediaWiki-powered website to coordinate their efforts and share their stories, until a different application on the server where it resided got hacked and the wiki got taken down as a precaution. That was last September, and the community became somewhat “lost” this winter as a result. It didn’t stop us ‘hashing, of course: the algorithm’s open-source and so are many of its implementations, so I was able to sink into a disgusting hole in November, for example. But we’d lost the digital “village square” of our community.

Graph of Dan's dissertation progress as the deadline creeps closer — My dissertation “burndown” is characterised on my whiteboard by two variables: outstanding issues (blue) and wordcount (red). There are… a few problems.

So I emailed Davean, who does techy things for xkcd, and said that I’d like to take over the Geohashing wiki but that I’d first like (a) his or Randall’s blessing to do so, and ideally (b) a backup of the pages of the site as it last-stood. Apparently I thought that my new job plus finishing my dissertation plus trying to move house plus all of the usual things I fill my time with wasn’t enough and I needed a mini side-project, because when I finally got the go-ahead at the end of last month I (re)launched geohashing.site. Take a look, if you like. If you’ve never been Geohashing before, there’s never been a more-obscure time to start!

Luckily, it’s not been a significant time-sink for me: members of the geohashing community quickly stepped up to help me modernise content, fix bots, update hyperlinks and the like. I took the opportunity to fix a few things that had always bugged me about the old site, like the mobile-unfriendly interface and the inability to upload GPX files, and laid the groundwork to make bigger changes down the road (like changing the way that inline maps are displayed, a popular community request).

So yeah: Geohashing’s back, not that it ever went away, and I got to be part of the mission to make it so. I feel like I am, as geohashers say… out standing in my field.

How to explain academic publishing to a five year old

This article is a repost promoting content originally published elsewhere. See more things Dan's reposted.

Last week I tweeted a cow-based academic publishing analogy in response to the prompt in the title, and the replies and quote-tweets extended the metaphor so gloriously, so creatively, so bleakly and hilariously at the same time, that I’ve pulled my favourites together below.

Here’s the original tweet:

Cows make milk. They milk themselves.

Other cows check the milk (for free).

Cows – get this – PAY THE FARMER to take the milk away.

Then the farmer (you won’t believe this, honestly) sells the milk *back to the cows.* #academicpublishing https://t.co/mgYneu4Goi

Ned Potter

Speaking as a goat, I approve of open access.

When I took a diversion from my various computer science related qualifications to study psychotherapy for a while, I was amazed to discover how fortunate we computer scientists are that so much of our literature is published open access. It probably comes from the culture of the discipline, whose forefathers were publishing their work as open-source software or on the Internet long before academic journals reached the online space. But even here, there’s journal drama and all the kinds of problems that Ned (and the people who replied to his tweet) joke about.

Note #16055

That moment when you realise, to your immense surprise, that the research you’ve spent most of the year on might actually demonstrate the thing you set out to test after all. 😲
Screw you, null hypothesis.

“One of the best things about working at The Bodleian… Pretending to be a PhD student…”

This article is a repost promoting content originally published elsewhere. See more things Dan's reposted.

One of the best things about working at The Bodleian Libraries, University of Oxford? Pretending to be a PhD student for a photo shoot! Watch out for me appearing in a website near you…

Natalie Awdry (LinkedIn)

My team and I do get up to some unusual stuff, it’s true. I took part in this photoshoot, too:

Dan in the library, viewed through the window.

I’m absolutely not above selling out myself and my family for the benefit of some stock photos for the University, it seems. The sharp-eyed might even have spotted the kids in this video promoting the Ashmolean or a recent tweet by the Bodleian…

Letters After My Name

Results day today, and so I finally get to find out whether or not I get a degree in exchange for my last five years at University. And I do. I’m now entitled to put letters after my name, which is nice.

I’ve got a lower second, which is (I know) less than I’m capable of, but considering my resits and other lark last year, it’s exactly what I expected, so that’s great. Was damn pleased to see that my dissertation got a first.

Now I suppose I’d better get on with the rest of my life.

Morning Mysteries 1 – 1 Scatman Dan

I woke up this morning to two mysteries:

1. Why had I set my alarm for 8:30am?

2. Why do I have a nose bleed?

I’ve solved the former: Claire needs to move her car (which is parked on double-yellows outside) or she’ll get ticketed when the morning wardens come by (morning wardens? they’re like traffic wardens, but they put tickets on people who still look half-asleep). The latter? No idea.

Yay; we’re off to the Borth Animalarium today, to look at meerkats! Followed by Troma Night!

My ‘Online Bank’ project isn’t going very well. So far it allows you to add Books to a Cart and get the total cost of them all. Which isn’t terribly useful, because that sounds more like a bookstore to me than an online bank… but I couldn’t find an example online about how to use EJBs to make an online bank, just a bookstore. D’oh.

Dissertation Hand-In

[this post has been partially damaged during a server failure on Sunday 11th July 2004, and it has been possible to recover only a part of it]

I handed in my dissertation yesterday. What a farce. Here’s the approximate order of things.

08:30 – Get up. Compile a postscript (.ps) copy of my dissertation, and upload both this and the .tex source files to central.aber.ac.uk. Start walking up to campus (Bryn offers to give me a lift, but I feel energetic, so I bound on up the hill).

09:00 – Reach campus and pay for £5 of printer credit (100 pages). Find a workstation room, log into central, and lpr -Puserarea diss-final.ps (print) it. Marvellous. Pick up the printout.

09:15 – Drop my (printed) dissertation off at the Library to be hardback bound. Everything’s going splendidly. Trek back down town. The hand-in window is 14:00-16:00, so I’ve got loads of time.

13:30 – Arrive back on campus, this time with two CDs (containing the source code and sample data for the project). I buy sticky things from the Union with which to attach them to the inside cover of my dissertation, and then trek to the Library to pick up the masterpiece.

13:45 – Hmm. The binding office seems to be closed. Guess they’re on lunch. I go to return a library book from the Physical Sciences Library, …

Update, 11 January 2020: As the tail-end of this post appears to be lost forever, I’ll fill in the essence of it from memory: after a leisurely morning/early afternoon of getting my dissertation printed and bound for delivery, well-ahead of the deadline later in the day and thus avoiding the mad rush for the printers and binders later in the day, I arrived at the hand-in point only to be told I was supposed to be handing over two copies, not one, and so I ended up caught up in the mad rush I’d been smugly avoiding after all.

Dissertation Proofreaders Needed

[chez geek card]

Yay. Now I’m in a fab bouncey mood and ready to crack on with the next 10,000 words of my dissertation.

People have kindly been offering to proof-read it for me on Sunday night – this is most welcome: if anybody else wants to, you can too: just drop me a comment or a message or something, and I’ll e-mail you it. I presume you’ll all prefer Acrobat .PDFs than PostScript .PS files, yeh?

On which note; everybody’s being really considerate of my need to get this thing done – leaving me to do it where they’re likely to be a distraction; not suggesting really cool things we could be doing right now (except for the above card, ahem), etc. Thank you all, guys!
