Dan Q archived GC7Q96B Oxford’s Long-Lost Zoo

This checkin to GC7Q96B Oxford's Long-Lost Zoo reflects a geocaching.com log entry. See more of Dan's cache logs.

This has been muggled hard. I no longer live very close, so I’m removing the cache: I’ve extracted the remnants of the container from the GZ.

Shame to lose such a beautiful container, but it had a good long life and told many people the unusual story of this site, so it’s all good.

Will swapping out electric car batteries catch on?

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

Without even a touch of the steering wheel, the electric car reverses autonomously into the recharging station

Underside of a car with a removable battery.

I won’t be plugging it in though, instead, the battery will be swapped for a fresh one, at this facility in Norway belonging to Chinese electric carmaker, Nio.

The technology is already widespread in China, but the new Power Swap Station, just south of Oslo, is Europe’s first.

This is what I’ve been saying for years would be a better strategy for electric vehicles. Instead of charging them (the time needed to charge is their single biggest weakness compared to fuelled vehicles) we should be doing battery swaps. A decade or two ago I spoke hopefully for some kind of standardised connector and removal interface, probably below the vehicle, through which battery cells could be swapped-out by robots operating in a pit. Recovered batteries could be recharged and reconditioned by the robots at their own pace. People could still charge their cars in a plug-in manner at their homes or elsewhere.

You’d pay for the difference in charge between the old and replacement battery, plus a service charge for being part of the battery-swap network, and you’d be set. Car manufacturers could standardise on battery designs, much like the shipping industry long-ago standardised on container dimensions and whatnot, to take advantage of compatibility with the wider network.

Rather than having different sizes of battery, vehicles could be differentiated by the number of serial battery units installed. A lorry might need four or five units; a large car two; a small car one, etc. If the interface is standardised then all the robots need to be able to do is install and remove them, however many there are.

This is far from an unprecedented concept: the centuries-old idea of stagecoaches (and, later, mail coaches) used the same idea, but with the horses being changed at coaching inns rather. Did you know that the “stage” in stagecoach refers to the fact that their journey would be broken into stages by these quick stops?

Anyway: I dismayed a little when I saw every EV manufacturer come up with their own battery standards, co=operating only as far as the plug-in charging interfaces (and then, only gradually and not completely!). But I’m given fresh hope by this discovery that China’s trying to make it work, and Nio‘s movement in Norway is exciting too. Maybe we’ll get there someday.

Incidentally: here’s a great video about how AC charging works (with a US/type-1 centric focus), which briefly touches upon why battery swaps aren’t necessarily an easy problem to solve.

Dan Q found GC49ERR #5 Billy Wynt – Up Top

This checkin to GC49ERR #5 Billy Wynt - Up Top reflects a geocaching.com log entry. See more of Dan's cache logs.

Wow, definitely had to go off the beaten track for this one. I took a route up and tightly alongside the fence, and only after getting to the GZ did I discover the easier way. Still a tough thing to find with the foliage so verdant. TFTC and thanks for the walk and the view, too!

From the top of the folly I can just make out my hotel in the distance (see photo)! Better go get some breakfast!

Dan, on a hilltop, points down into the valley between this and the next hill over. Where he's pointing is a white-and-brown-brick building with a grey slate roof in the iconic shape of a Travelodge hotel.

Dan Q couldn’t find GC49EQW #3 Billy Wynt – Feeling Peckish

This checkin to GC49EQW #3 Billy Wynt - Feeling Peckish reflects a geocaching.com log entry. See more of Dan's cache logs.

Had to give up on this one. 😢
Between a great fix, a clear clue, and CO maintenance only last week I figured this was a sure thing. But somehow it wasn’t to be, no matter how many nettle stings I endured in the hunt.

Dan Q found GC49AEB #1 Billy Wynt – Cattle Grid

This checkin to GC49AEB #1 Billy Wynt - Cattle Grid reflects a geocaching.com log entry. See more of Dan's cache logs.

Woke earlier than my friends who’d been to a wedding last night, and used that as an excuse for a quick walk up the hill. Easy find: second place I looked! TFTC. Greetings from Oxfordshire!

Dan stands on a rough muddy forest trail ad waves at the camera.

Dan Q found GC9822Z Church Micro 13932…Oxford – Baptist

This checkin to GC9822Z Church Micro 13932...Oxford - Baptist reflects a geocaching.com log entry. See more of Dan's cache logs.

Having nabbed one of the coveted parking spaces to run an errand in Summertown, I nipped over here to find this cache, too. Coordinates were spot on but I couldn’t see the cache, so I took the advice of a previous log and plunged my hand into what I thought was a likely hiding place and came out with the cache in hand. TFTC.

Wonder Syndrome

Ruth wrote an excellent post this month entitled Wonder Syndrome. It attempts to reframe imposter syndrome (which is strongly, perhaps disproportionately, present in tech fields) as a positive indicator that there’s still more to learn:

Being aware of the boundaries of our knowledge doesn’t make us imposters, it makes us explorers. I’m going to start calling mine “Wonder Syndrome”, and allowing myself to be awed by how much I still have to learn, and then focusing in and carrying on with what I’m doing because although I may not reach the stars, I’ve come a long way up the mountain. I can learn these things, I can solve these problems, and I will.

This really resonated with me, and not just because I’ve totally bought into the Automattic creed, which literally opens with the assertion that “I will never stop learning”. (Other parts of the creed feel like they parallel Ruth’s post, too…)

Dan and Jacob look at a piece of code together; Dan is smiling but Jacob looks disgusted.
I don’t recall exactly what I’m advising a fellow Three Rings developer to do, here, but I don’t think he’s happy about it.

I just spent a week at a Three Rings DCamp (a “hackathon”, kinda), and for the umpteenth time had the experience of feeling like everybody thinks I know everything, while on the inside I still feel like I’m still guessing a third of the time (and on StackOverflow for another third!).

The same’s true at work: people ask me questions about things that I suppose, objectively, are my “specialist subjects” – web standards, application security, progressive enhancement, VAT for some reason – and even where I’m able to help, I often get that nagging feeling like there must be somebody better than me they could have gone to?

Pair of Venn diagrams. The first, titled "In my head", shows "things Dan is good at" as a subset of "things others are good at". The second, titled "Reality", shows an intersection between "things others are good at" and "things Dan is good at" but plenty of unshared space in each.
You’ve probably seen diagrams like this before. After all: I’m not smart or talented enough to invent anything like this and I don’t know why you’d listen to anything I have to say on the subject anyway. 😂

You might assume that I love Ruth’s post principally because it plays to my vanity. The post describes two kinds of knowledgeable developers, who are differentiated primarily by their attitude to learning. One is satisfied with the niche they’ve carved out for themselves and the status that comes with it and are content to rest on their laurels; the other is driven to keep pushing and learning more and always hungry for the next opportunity to grow. And the latter category… Ruth’s named after me.

Woman on laptop, looking concerned towards camera, captioned "are you even good enough to have imposter syndrome?"
Wait, what if I’m not Have I been faking it this entire blog post?

Bnd while I love the post, my gut feeling to being named after such an ideal actually makes me slightly uncomfortable. The specific sentence that gets me is (emphasis mine):

Dans have no interest in being better than other people, they just want to know more than they did yesterday.

I wish that was me, but I’m actually moderately-strongly motivated by a desire to feel like I’m the smartest person in the room! I’m getting this urge under control (I’m pretty sure I was intolerable as a child and have been improving by instalments since then!). Firstly, because it’s an antisocial pattern to foster, but also because it limits my ability to learn new things to have to go through the awkward, mistake-filled “I’m a complete amateur at this!” phase. But even as I work on this I still get that niggling urge, more often than I’d like, to “show off”.

Of course, it could well be that what I’m doing right now is catastrophising. I’m taking a nice thing somebody’s said about me, picking the one part of it that I find hardest to feel represents me, and deciding that I must be a fraud. Soo… imposter syndrome, I guess. Damn.

Or to put it a better way: Wonder Syndrome. I guess this is another area for self-improvement.

(I’m definitely adopting Wonder Syndrome into my vocabulary, as an exercise in mitigating imposter syndrome. If you’ve not read Ruth’s post in full, you should go and do that next.)

Dan Q found GC8QB2N INWT #12: Cleverest Crow?

This checkin to GC8QB2N INWT #12: Cleverest Crow? reflects a geocaching.com log entry. See more of Dan's cache logs.

Continuing our reverse-order explore of some of these caches closest to our accommodation for the week. Little 5-year-old John found this one and came proudly out from its hiding place with it in hand. TFTC.

Logbook very wet, hard to sign.

Dan Q found GC8QB3G INWT #13: Scalewra Settlement

This checkin to GC8QB3G INWT #13: Scalewra Settlement reflects a geocaching.com log entry. See more of Dan's cache logs.

Some fellow volunteers from a nonprofit I help run and I are staying at nearby Myddelton Lodge and came out to find a couple of local caches on our lunch break. This was the first, and my new-to-geocaching colleague Paul was first to put his hands on the cache. Nice one. TFTC.

Log very wet, almost impossible to sign.

Dan and John stand on a two-plank footbridge over a stream alongside Dan's fellow Three Rings volunteer Paul, looking uphill towards the camera. The stream runs through moderately-dense deciduous woodland and the forest floor is covered with greenery.
