<p>Not just drizzling, but a full on, thunder-and-lightning style downpour. It’s
been so long without a serious bit of a rain that the grass and plants are all
dead and the trees are dropping leaves far too early. But finally we’ve had the
kind of deluge that’s going to soak the ground through and give everything a
proper drink.</p>

<p>As a child I remember hearing a song called “here comes the rain” or something
similar, and thinking that it was mad…who would be excited for rain? The
artist explained that rain is life-or-death in some parts of the world and
saving a harvest or giving drinking water can mean everything.</p>

<p>It’s not that serious here - I just like my plants and trees. But I’m glad it’s
rained, and we got to sit and watch the lightning and listen to the thunder.</p>

<p>Holiday tomorrow so probably little in the way of posts. And we’ll be driving
past Leeds festival as it empties.

months.<!--more--> The thing is, I’m not so sure he’s a toddler either. It’s
the lack of <em>toddling</em> that does it. He can stand while holding onto something.
Actually, he can stand <strong>without</strong> holding onto something - it’s just that he
doesn’t <em>think</em> that he can. Sometimes we trick him by giving him something to
hold, and in the few seconds after he has grabbed it (but before he realises what he’s
doing) he stands proud and free.</p>

<p>Still no words, either. Lots of shouts that could very easily become words.
It’s going to be a short loud word that he gets the hang of - our only hope is
that it isn’t “gun”. My 7-year-old knows this, and so is pretty determined that
it should be “gun”.</p>

<p>No words and no walking (or even real standing), but he’s a speed-demon when it
comes to crawling and to climbing. Who would have thought that somebody who
couldn’t stand could scale a ladder, then go over the top and head first down a
slide? Relatedly, he’s also got the first of what I’m sure
will be many head bumps. The child has no fear, apart from, apparently, when it
comes to standing without holding onto anything.</p>

<p>He’s nailed clapping and waving, and is a dab hand at pointing too. Drumming,
both with hands and accessories. His favourite is the pan drawer, which he can
open and close, fuck up, and then smash the pans off of the floor/wall for
extra noise.</p>

<p>As of a few days ago, he dropped down to being a one-nap baby and he’s so much
happier. It’s a real pain when he only does a 45 minute nap, but we no longer
spend hours on end trying to squeeze in a second nap that he doesn’t want to
have. I reminded myself when we had this child to not stress too much about
doing things <em>right</em> and to just go with whatever works for them. Then I went
ahead and forgot it all over again. When you remember that you can just do what
works for your child and then it works…well, why can’t I remember that?</p>

<p>He’s got two teeth now, and occasionally is irrationally angry…no, wait. He’s
<strong>always</strong> irrational, often angry, and very often irrationally angry. However,
we often attribute some of this anger to his teeth and the pain of growing new
ones. Maybe it’s some other pain, or just the general anguish of existing in a
world where nobody can understand you. But it’s easier to say “are your teeth
hurting?” and to give him Calpol.</p>

<p>He’s developing cheekiness and craziness. Sometimes when he starts to get tired
and he’s had a meal, he’ll just crawl around the kitchen table shrieking. I
<em>think</em> he’s imitating his older siblings who like to run and do the same
thing. He loves a wrestle too, but his only move is to crawl up to me and then
dip his head at me. That’s my cue to flip him upside down and generally tackle
him. Successfully flipped, he crawls away, and then crawls back at me to repeat
the process.</p>

<p>He’s a lot of fun if he’s all you’re dealing with and you’ve got energy. He’s a
lot less fun if you’re trying to achieve something and he woke up at 5:30am and
wants to post electronics in the toilet while you’re trying to wee.</p>]]></content><author><name>Matt</name></author><category term="parenting" /><category term="kids" /><summary type="html"><![CDATA[My baby boy isn’t really a baby any more, at the ripe old age of 13 months.]]></summary></entry><entry><title type="html">Play Dates</title><link href="https://dogdogfish.com/blog/2026/08/24/play-dates/" rel="alternate" type="text/html" title="Play Dates" /><published>2026-08-24T00:00:00+00:00</published><updated>2026-08-24T00:00:00+00:00</updated><id>https://dogdogfish.com/blog/2026/08/24/play-dates</id><content type="html" xml:base="https://dogdogfish.com/blog/2026/08/24/play-dates/"><![CDATA[<p>Yesterday it was my son’s 7th birthday party.<!--more--> He had four friends
over (and one younger sibling) and they had a blast. They tore through our
house and garden like a whirlwind of giggles, shouts and squeals. My boy had
looked forward to it for weeks and it was probably the
most fun he’d had all summer.</p>

<p>What’s more, it was <em>less</em> work for us. Looking after one hyperactive
7-year-old is <strong>harder</strong> than looking after 5 of them. At a time when parents
are doing more parenting than ever, why aren’t we taking advantage of
play dates more?</p>

<h2 id="what-they-took-from-us">What they took from us</h2>

<p>To hear tell of our parents’ and grandparents’ childhoods, this was the norm. Every night after school. Every
day during the holidays. Children everywhere, self-policing and
self-entertaining. The data bears that out, and what would once have been
classed as “intensive” parenting is the new “neglectful” parenting.</p>

<p>We offered ‘drop-off and pick-up’ and only one of the parents took us up on it - the rest stayed for the duration of the party. It was genuinely nice - a lot of our conversations were on the hardships of raising young kids, especially during the long summer holidays. This new future of child-raising seems objectively worse for parents, and yet there doesn’t appear to be any evidence that it’s better for children. If anything, there’s growing evidence that it’s worse for them.</p>

<p>But people aren’t stupid and generally don’t act in sustained irrational
ways…how did we get here? The past is the future that they took from us. Who
is ‘they’?</p>

<h2 id="a-diagnosis">A Diagnosis</h2>

<p>In the 1960s and 1970s, as car traffic rose, children died at the hands of motorists. Then, over the subsequent decades, the number of children’s deaths fell. Not mainly because of any safety intervention or
campaign, but because parents simply stopped letting their children out. In
1971, 80% of 7-8 year olds travelled to school independently. By 1990, it was 9%.</p>

<p>Children lost their immediately available third place, because as a society we
granted it to cars instead.</p>

<p>Now, the roads (and pavements) are much safer than they were back then, and yet
the children still don’t have a place to play on their doorstep. Why? Because streets
don’t just need to be safe. They need to be bustling. An empty street where nobody plays isn’t an attractive proposition for a child.
A street with a bunch of kids playing is. When your child looks out of their
window, which do they see? We gave up our neighbourhood for cars, and by the time we made them safe again, nobody was playing outside any more.</p>

<p>Who is they, then? Parents in the 1980s who cared for their kids? Motorists in
the 1970s who didn’t drive carefully enough? Governments in the 1960s who
didn’t realise what they needed to protect? ‘They’ is always just ‘us’, but
without the information that we have now.</p>

<h2 id="a-coordination-problem">A Coordination Problem</h2>

<p>So now, what used to be a child’s job (looking out of the window) has become an
adult’s job: organising a play date. Adults (especially me) are awkward about
things in a way kids aren’t. What if my house isn’t tidy enough? What if I cook
the wrong food? What if I allow the wrong type of toy or screen? What if my
child behaves badly? Or the other child gets hurt? What if they don’t agree
with my parenting approach?</p>

<p>The same logic might explain why those parents stayed at the party. Maybe they
don’t trust us, maybe they were desperate for adult conversation and bonding
with those sharing their struggles, or maybe leaving felt rude. Parents who
wish they could get a free afternoon and parents who want somebody to talk to
end up behaving the same way. It’s one big jumble of social awkwardness.</p>

<p>The childcare might be easier, but navigating the social judo a play date set-up requires is real work that takes real effort. And as anybody who spends
any time studying large amounts of human data will tell you, if it takes real
effort, it’s probably not going to happen much.</p>

<p>This coordination cost is actually multiplied by the fact that it involves
multiple decision makers - I can’t unilaterally decide to organise a play date
as I’m neither the primary caregiver, nor allowed on the school mums’ WhatsApp
group (for people’s phone numbers).</p>

<h2 id="the-solution">The Solution</h2>

<p>I don’t have one, I’m afraid. We’ve taken effortless child-organised play on
our doorsteps and replaced it with parentally-negotiated hosting, and as a
result, our kids spend less time playing with each other than they ever have.
That sucks for kids, and it sucks for parents too. Maybe we need a standing
engagement (organise once, benefit forever) or a rota…somebody has to go
first, I guess.</p>]]></content><author><name>Matt</name></author><category term="parenting" /><category term="kids" /><summary type="html"><![CDATA[Yesterday it was my son’s 7th birthday party.]]></summary></entry><entry><title type="html">Castle</title><link href="https://dogdogfish.com/blog/2026/08/20/castle/" rel="alternate" type="text/html" title="Castle" /><published>2026-08-20T00:00:00+00:00</published><updated>2026-08-20T00:00:00+00:00</updated><id>https://dogdogfish.com/blog/2026/08/20/castle</id><content type="html" xml:base="https://dogdogfish.com/blog/2026/08/20/castle/"><![CDATA[<p>Maybe I don’t need to buy a castle after all.<!--more--></p>

<p>For as long as I can remember, I’ve wanted to buy (and live) in a castle.
They’re generally not cheap but in the UK (and to an even greater extent in
France), they’re not completely preposterously unaffordable. I’ve worked in
tech a long time and, if I pulled out all the stops, ruined myself financially, and chose a cheap area
(Scottish Borders, Wales, Argyll &amp; Bute) I could probably afford a smallish
castle.</p>

<p>I spend a lot of time on Rightmove imagining this. I’ve even called up an
Estate Agent before about a castle.</p>

<p>The problem is, I now live in a big house with a big garden. It’s too big, to be honest. Sure,
the bathrooms could be bigger. But we have a room downstairs with a piano and
bookcases in it and, while beautiful, it rarely gets anybody in it. It’s my
dream room (except it needs a leather armchair or two and a drinks globe)…and
I never go in there.</p>

<p>So with a large (but certainly not castle-sized) house I have too much space
and a room I don’t know what to do with. I also have about half an acre of
garden and again, it’s too big. I love wandering around in it, but maintaining
it is a pain. The last castle I looked at had 27 acres. Can you imagine?</p>

<p>I still lust after castles and find it hard to believe that I’ll never live in
one. But honestly, I don’t actually think I should buy one.</p>]]></content><author><name>Matt</name></author><category term="life" /><summary type="html"><![CDATA[Maybe I don’t need to buy a castle after all.]]></summary></entry><entry><title type="html">Digital Immortality</title><link href="https://dogdogfish.com/blog/2026/08/19/digital-immortality/" rel="alternate" type="text/html" title="Digital Immortality" /><published>2026-08-19T00:00:00+00:00</published><updated>2026-08-19T00:00:00+00:00</updated><id>https://dogdogfish.com/blog/2026/08/19/digital-immortality</id><content type="html" xml:base="https://dogdogfish.com/blog/2026/08/19/digital-immortality/"><![CDATA[<p>Even now, as you’re reading these words, hundreds of robots are poring over

science” but today I’d like to talk about <em>insights</em>.<!--more--> For me,
insights work is all about changing minds. Perhaps ‘changing’ is too strong and
adversarial a term: if we give a decision maker extra confidence, that’s
probably still OK. But the gold-standard of a good insight is that it leads to
somebody changing what they were going to do.</p>

<p>It’s much less certain than a bunch of other data work because it deeply
involves people and people are deeply unpredictable. If you can sit and work
closely with the person you’re trying to influence, it’s much easier to
understand what they’re motivated by, what they believe the key facts are, and
then how you can fit into their process and offer them value.</p>

<p>But so much of very senior insights work isn’t like that at all, and much more
closely resembles research work in nature. You spend a while working on an area
and building expertise, then you take a chance. You find something that you
think is interesting and <em>should</em> change minds, but are you right? Have you
distilled it perfectly into just the right bite-sized chunk? Have you packaged
it in just the right way? And then when you launch it, do you hit the right
people at the right time?</p>

<p>In my experience, senior executives have a few key
<em>grounding numbers</em>: snippets that help shape (and explain) their position on
topics.</p>

<p>“I know that the average person on Facebook has 372 friends”</p>

<p>or, every data scientist’s least favourite example:</p>

<p>“People with 10 friends within their first 24 hours are 75% more likely to be
retained”</p>

<p>Good insights-based data science work is creating those snippets and getting
them to land. I imagine it’s fairly similar to a lot of work in politics, where
you’re trying to get a slogan or a data point out into the general
consciousness.</p>

<p>However, even after all that work, and even if you got everything right, you can still sometimes
miss the mark. Maybe your stakeholder’s priorities have shifted, or they’re
getting pressure from elsewhere that they can’t ignore, or they didn’t even
read what you shared. You necessarily have
less information than them, and so while you might think your thing is
critically important, they might disagree.</p>

<p>If all of this doesn’t sound like data work…maybe that’s because it’s not.
At senior levels across so many careers, <em>influence</em> becomes the mark of
success and your skillset is just the tool you lean upon to have that
influence. A senior engineer, designer, user researcher, or data scientist at a tech company has to be technically strong.
But they need to know how to have an impact as well, and having an impact means
being able to influence whoever makes the decisions. I once read somewhere that
by the time you’re a “Senior X” you should be able to pick up anything
technically required. To be Staff+, it’s all about how you manage to apply it.</p>

<p>Anyway, I just launched a bit of work and I’ve got no idea if it’s going to
land or not. I agonised over it for a few days and polished it as best I could,
but now it’s in the lap of the Gods. God-speed, little insight. Land well, and
let’s see what tomorrow brings.</p>]]></content><author><name>Matt</name></author><category term="data" /><summary type="html"><![CDATA[There are a bunch of different types of work that are broadly called “data science” but today I’d like to talk about insights.]]></summary></entry><entry><title type="html">Ill</title><link href="https://dogdogfish.com/blog/2026/08/17/ill/" rel="alternate" type="text/html" title="Ill" /><published>2026-08-17T00:00:00+00:00</published><updated>2026-08-17T00:00:00+00:00</updated><id>https://dogdogfish.com/blog/2026/08/17/ill</id><content type="html" xml:base="https://dogdogfish.com/blog/2026/08/17/ill/"><![CDATA[<p>I’ve been all kinds (well, 2) of ill recently and it’s rubbish.<!--more--> Last
weekend I had (I think) COVID - something along those lines anyway. Then on
Wednesday or Thursday my wife and six-year-old both had some sort of norovirus.
Lots of sick. Very unpleasant for them, and I was left trying to hold things
together.</p>

<p>I thought I’d escaped…and then on Saturday night, after sharing an ice-cream
spoon with my youngest two…I felt a rumbling in my tummmy and oh no. Sick.
Lots of sick.</p>

<p>I quarantined in the annexe for Saturday night and was useless on Sunday (which
meant my poor, just-recovering wife had to take over all day). It’s just gone
Monday and I battled on through at work but still feel a bit dodgy.</p>

<p>I don’t note any of this for entertainment purposes, but because I think it’s
good to actually write down when I’m ill because otherwise I forget. I assume
I’m never ill and then when somebody asks when I was last ill, I genuinely
can’t remember. So here I was ill.</p>

<p>I’ll do a small bit of psychologising…though. I’m very unconcerned about
illness and don’t take even the smallest steps to avoid it. This baffles my
wife. My general philosophy is that being sick happens so rarely, and isn’t so
bad when it happens, that any amount of effort to avoid it is a cost that I
don’t want to incur. Even while I was being sick and
then couldn’t sleep all night, I remember thinking <em>“this is still better than
worrying about getting sick”</em>.</p>

<p>I’m two days past now and perhaps I should have taken a few slight precautions
(like not sharing the towel and spoon of somebody who was being sick &lt; 24 hours
ago). But overall, I still think my trade is broadly a good one.</p>]]></content><author><name>Matt</name></author><category term="life" /><summary type="html"><![CDATA[I’ve been all kinds (well, 2) of ill recently and it’s rubbish.]]></summary></entry><entry><title type="html">One Big Decision</title><link href="https://dogdogfish.com/blog/2026/08/10/one-big-decision/" rel="alternate" type="text/html" title="One Big Decision" /><published>2026-08-10T00:00:00+00:00</published><updated>2026-08-10T00:00:00+00:00</updated><id>https://dogdogfish.com/blog/2026/08/10/one-big-decision</id><content type="html" xml:base="https://dogdogfish.com/blog/2026/08/10/one-big-decision/"><![CDATA[<p>I’ve been thinking about MRR (monthly recurring revenue) versus ARR (annual)
and the psychology of those two things.<!--more--> It’s pretty clear that
businesses <strong>love</strong> the idea of recurring revenue, and given a choice between a
subscription or more initial outlay, they’ll take the subscription every time.</p>

<p>Theoretically, paying monthly for a service should be 12 small decisions and
paying annually (or once) should be one big decision. Except it isn’t, is it?
Paying monthly for something is one small decision followed by
nothing…inaction.</p>

<p>That’s why businesses prefer subscriptions - because they turn initial interest
into regular money, rather than one-off money. Then they’re banking on the fact
that you don’t want to re-evaluate all your subscriptions regularly, and the
hassle of doing something (cancelling them) is more than the hassle of doing
nothing.</p>

<p>However, you’ll also find most SaaS companies will give you a discount if you
pay for the year upfront. That way they get all the money in now and take out
the risk of you cancelling early on, but still get to stick you on a
subscription and take your money next year unless you remember.</p>

<p>The gap between monthly and annual pricing should be pretty informative in a
well run business - letting you know about how much the company values
immediate money and how wary they are of immediate churn, versus their ability
to have customers stick around.</p>]]></content><author><name>Matt</name></author><category term="psychology" /><summary type="html"><![CDATA[I’ve been thinking about MRR (monthly recurring revenue) versus ARR (annual) and the psychology of those two things.]]></summary></entry><entry><title type="html">Privilege</title><link href="https://dogdogfish.com/blog/2026/08/07/privilege/" rel="alternate" type="text/html" title="Privilege" /><published>2026-08-07T00:00:00+00:00</published><updated>2026-08-07T00:00:00+00:00</updated><id>https://dogdogfish.com/blog/2026/08/07/privilege</id><content type="html" xml:base="https://dogdogfish.com/blog/2026/08/07/privilege/"><![CDATA[<p>After a week of ghosting round the house by myself, my wife and children and

one-year-old to wait for the onslaught. An onslaught that arrived at 7am on the

big brother. A one-year-old is chaotic. All three of them together is something
else.</p>
