Found with Ruth after coming out to explore the spectacular Roman villa. We’d supposed to have been out of the Isle of Man celebrating our anniversary, but our ‘plane got cancelled, so we’ve opted for staying at home and doing local cycling expeditions instead. SL, TFTC.

Well this was a challenge! The woods threw off my GPS, but I’d brought a backup device so I averaged between them and found a likely GZ. The dog and I did an increasingly large spiral, checking all the obvious hiding spots, to no avail. Returning to our start point we began another pass, and something caught my eye! It was the cache!

A few things had made it challenging:

  • I put the coordinates 13m from where the CO does. Could be the woods, but I’m not the first to say about this distance.
  • This cache is by no means a “regular”. It’s not even a “small”. It would fit inside a 35mm film canister, which in my mind makes it clearly a “micro”!
  • It wasn’t in the hiding place indicated by the hint! I found in on the ground, beneath leaf litter, with thanks to my energetic leaf-kicking geohound!

Signed log and returned cache to the nearest hiding spot that fits the hint, hopefully others will find it more easily than we did! TFTC from Demmy the Dog and I!

Maintenance check while walking the dog. Cleared some overgrown plants, but watch out because the nearby nettles ate still a little fierce (cache can be retrieved without a sting though!). Cache itself intact and healthy.

Found! Took a bit of a search, because I had looked at the hint image which shows several trees at the GZ that are no longer there, so I was left thinking I must be in the wrong place for a while! TFTC, and greetings from Oxfordshire, UK!

What a great statue! Cache was very easy to find; despite its camo it was very visible as I walked along the adjacent path. Thanks for bringing me out of my way on my walk from my hotel to the conference I’m attending, and TFTC. Greetings from Oxfordshire, UK!

Walking from my hotel to the site of a conference I’m attending, this morning, I stopped to find this cache. It took an embarrassingly long time for me to spot this sneaky little container! Greetings from Oxford, UK, and TFTC!

Saw the notification when this cache appeared near my house, which would normally be the point at which a race was kicked off between me and Go Catch for the FTF, before he inevitably got there first!

But this time around I was overseas when the listing went live and only found time to cycle out here from Stanton Harcourt this evening, after work. I’d visited the church here once before in service of the nearby multi, but it was nice to see a different side of it as well as an excellent hiding place.

TFTC!

Dan Q found GC7FB9H From Canterbury to the cache

Well that was quite the adventure!

The first wayoint is right across the road from where some work colleagues and I are staying for an “away week”. I decided to dash out during a break in the weather to try and solve this multi between meetings. But I was quickly confused because… this isn’t the way I was taught to do Roman numerals. I’d always been told that you should never have four of the same letter in a row, e.g. you should say XIV, not XIIII. Once I’d worked out what I was doing wrong, though, I was okay!

The second and third waypoints had me braving some frankly scary roads. The drivers here just don’t seem to stop unless you’re super assertive when you step out!

Once I had the final numbers and ran it through geochecker I realised that the cache must be very close to where I’d had lunch earlier today! Once I got there it took me a while to get to the right floor, after which the hint made things pretty obvious.

Great trail, really loved it. And just barely made it back before the rain really started hammering down. TFTC, FP awarded, and greetings from Oxford, UK!

Easy find while out for a ride, breaking in my new bike. Great ride, aside from the mayflies, which I must’ve ingested about a million of! As others have observed, the logbook has soaked to the point of disintegration and could do with replacement. Thanks though for a cache I’ve probably driven, walked out cycled past a hundred times before actually stopping to find it.

My GPSr dropped me next to a far older bit of architecture than the one that hosts the cache, but found after a short search. I’m staying nearby as part of a charity hackathon for a nonprofit I’m involved with, but came out for a walk and an explore while between other tasks. SL, TFTC.

Solving Jigidi… Again

(Just want the instructions? Scroll down.)

A year and a half ago I came up with a technique for intercepting the “shuffle” operation on jigsaw website Jigidi, allowing players to force the pieces to appear in a consecutive “stack” for ludicrously easy solving. I did this partially because I was annoyed that a collection of geocaches near me used Jigidi puzzles as a barrier to their coordinates1… but also because I enjoy hacking my way around artificially-imposed constraints on the Web (see, for example, my efforts last week to circumvent region-blocking on radio.garden).

My solver didn’t work for long: code changes at Jigidi’s end first made it harder, then made it impossible, to use the approach I suggested. That’s fine by me – I’d already got what I wanted – but the comments thread on that post suggests that there’s a lot of people who wish it still worked!2 And so I ignored the pleas of people who wanted me to re-develop a “Jigidi solver”. Until recently, when I once again needed to solve a jigsaw puzzle in order to find a geocache’s coordinates.

Making A Jigidi Helper

Rather than interfere with the code provided by Jigidi, I decided to take a more-abstract approach: swapping out the jigsaw’s image for one that would be easier.

This approach benefits from (a) having multiple mechanisms of application: query interception, DNS hijacking, etc., meaning that if one stops working then another one can be easily rolled-out, and (b) not relying so-heavily on the structure of Jigidi’s code (and therefore not being likely to “break” as a result of future upgrades to Jigidi’s platform).

Watch a video demonstrating the approach:

It’s not as powerful as my previous technique – more a “helper” than a “solver” – but it’s good enough to shave at least half the time off that I’d otherwise spend solving a Jigidi jigsaw, which means I get to spend more time out in the rain looking for lost tupperware. (If only geocaching were even the weirdest of my hobbies…)

How To Use The Jigidi Helper

To do this yourself and simplify your efforts to solve those annoying “all one colour” or otherwise super-frustrating jigsaw puzzles, here’s what you do:

  1. Visit a Jigidi jigsaw. Do not be logged-in to a Jigidi account.
  2. Copy my JavaScript code into your clipboard.
  3. Open your browser’s debug tools (usually F12). In the Console tab, paste it and press enter. You can close your debug tools again (F12) if you like.
  4. Press Jigidi’s “restart” button, next to the timer. The jigsaw will restart, but the picture will be replaced with one that’s easier-to-solve than most, as described below.
  5. Once you solve the jigsaw, the image will revert to normal (turn your screen around and show off your success to a friend!).

What makes it easier to solve?

The replacement image has the following characteristics that make it easier to solve than it might otherwise be:

  • Every piece has written on it the row and column it belongs in.
  • Every “column” is striped in a different colour.
  • Striped “bands” run along entire rows and columns.

To solve the jigsaw, start by grouping colours together, then start combining those that belong in the same column (based on the second digit on the piece). Join whole or partial columns together as you go.

I’ve been using this technique or related ones for over six months now and no code changes on Jigidi’s side have impacted upon it at all, so it’s probably got better longevity than the previous approach. I’m not entirely happy with it, and you might not be either, so feel free to fork my code and improve it: the legiblity of the numbers is sometimes suboptimal, and the colour banding repeats on larger jigsaws which I’d rather avoid. There’s probably also potential to improve colour-recognition by making the colour bands span the gaps between rows or columns of pieces, too, but more experiments are needed and, frankly, I’m not the right person for the job. For the second time, I’m going to abandon a tool that streamlines Jigidi solving because I’ve already gotten what I needed out of it, and I’ll leave it up to you if you want to come up with an improvement and share it with the community.

Footnotes

1 As I’ve mentioned before, and still nobody believes me: I’m not a fan of jigsaws! If you enjoy them, that’s great: grab a bucket of popcorn and a jigsaw and go wild… but don’t feel compelled to share either with me.

2 The comments also include asuper-helpful person called Rich who’s been manually solving people’s puzzles for them, and somebody called Perdita who “could be my grandmother” (except: no) with whom I enjoyed a conversation on- and off-line about the ethics of my technique. It’s one of the most-popular comment threads my blog has ever seen.

Found with the elder geokid plus my mother and sister while on a layover in Preston to break up our journey from Aviemore to Oxford. We’re getting to visit quite a few some circles this half term, both old and new plus some old-but-restored, many of which have earthcache or virtual caches!

Thanks for the geology lessons and the interesting location. Answers sent already, FP awarded, TFTC.

This checkin to GC6CTKF Cache Wars - Han Solo reflects a geocaching.com log entry. See more of Dan's cache logs.

Travelling down from Aviemore to Preston on a multi-stage journey back home to Oxfordshire, we stopped off at the visitor centre and took the tour of the wind farm. My 6 year old loves wind turbines and was really excited to see so many in one place and to get the opportunity to give one (turbine #42) a hug (pictured)!

The tour complete, I took a quick jog back to turbine #40 to find this geocache. As others have noted, it’s in bad nick – no container and damp log – but I was (barely) able to sign it.

TFTC in this awesome spot.
