Programming Is Not Math

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

When I learned to program, back when dinosaurs walked the earth and the internet had no cats, there was an idea: if you were good at math, you’d be good at programming. I was great at math as a kid, but perhaps because I didn’t like it much, no one steered me towards programming. I…

Cache that REQUIRES two people: should I explain why it requires two people before they set out, or not?

Hi, Founditt!

Next month, I expect to launch a multicache with a twist: it requires two people to go to two different waypoints at the same time in order to determine the coordinates of the final stage – it’s not physically possible for one person to do it alone (even if they go to one waypoint and then to the other).

I’ll be saying all of this on the cache page, of course. But I’m worried that some people might try to do it alone, and then get frustrated when they realise the reason that it’s not possible to do it alone. I’m considering explaining on the cache page exactly how I’ve made it impossible to do by yourself, but I’d rather not do this if I don’t have to: I think that the cache will be more interesting and exciting if you don’t know why you need two people until you’re in-the-field.

What do you think? If you saw a cache with a description like that in the first paragraph, explaining that you needed you and a friend to simultaneously visit two waypoints (and explicitly stating that there was no way to solve it by yourself), would you believe it? Or would you set out by yourself anyway?

tl;dr: a multicache description says that you need to go to a waypoint and send a friend to a different waypoint, at the same time, but doesn’t tell you why until you get there – do you believe it?

EDIT: Wow; this has gotten popular. Once the cache is in place and people have begun finding it, I’d be happy to make a post here explaining how I did it. In the meantime, if you’re outside of the UK and want a few more teaser details, drop me a PM. If you’re inside the UK, or travel here often, then keep an eye out for the launch of GC591VV – “You Can’t Do It Alone!”.

Six Tiny Months

On Monday, Tiny turned 6 months old. For half a year now, I’ve been a parent. It still feels pretty weird to call myself that, though. Parent is a word that conjures up a mental image of someone strong, nurturing, patient, and above all who knows all the answers. In many ways, I feel more like I’m discovering life alongside my daughter than guiding her along the path.

Being out-and-about with a baby is a whole different experience. Strangers will strike up a conversation – and, more amazingly still, I don’t usually mind. Tiny is such a blessing that I can’t begrudge others a few minutes of cooing. The biggest difference isn’t other people, though.

Ruth’s just written about her first six months of being a parent. It’s worth a read.

Côte de Whatnow? (Or: Yorkshire, I love you.)

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

I’ve just been looking at the map of today’s stage of Le Tour de France Yorkshire (inexplicably starting in England).The map lists the biggest hills on the route, and despite this section of the route being in England, the names are prefaced “Côte de…”There’s three hills worthy of note on the maptoday. The first, Côte…

Little people, big shame

Sorry about the long break — I just wish I could tell you that it was because I’d been completely unable to find any awful examples of the pink/blue ‘colour bar’ in kids’ stuff. Sadly the truth is quite the reverse: there seems to be more of this crap every day, it gets demoralising, and…

ISEE-3

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

Back in early March, I posted comic #1337, Hack, about a wayward spacecraft. ISEE-3/ICE was returning to fly past Earth after many decades of wandering through space. It was still operational, and could potentially be sent on a new mission, but NASA no longer had the equipment to talk to it—and announced that reconstructing the equipment…

The quietest (Mega)Lounge yet? Ever?

[this post was originally made to a private subreddit]

As I’ve made my way up through the lounges, I’ve discovered – as you’d expect – that each has been quieter than the one that preceded it. Does this trend continue, I wonder: do we end with somebody (Greypo, I guess!) talking to themselves? Or is the “dip” here in IX a temporary thing, because IX is so-clearly a “passing-through” place as people work their way up to the fabled X.

I’m not sure. But I’m hoping to find out.
