EGXchange – a digital EGX wallet

I’ve just launched EGXchange.org, a digital wallet for new currency Emma Goldcoin, which I’ve mentioned previously (including a discussion with the author in my comments section).

Homepage of EGXchange.org, showing the slogan "Everybody has an EGX wallet. Log in to yours now."
Of course, you don’t strictly need a digital wallet to use EGX. But as we’re in a culture where people invariably ask “is there an app for it?”, I thought I’d make one.

You can install it as an offline-first progressive web application, which means that this could be the first ever digital currency to have an app that works without an Internet connection. That’s probably something no other digital currency can claim to have, right?

Here’s what it looks like if I send 0.1 EGX to my friend Chris using the app:

Naturally, I wouldn’t be backing Emma Goldcoin if it didn’t represent such a brilliant step up better-known digital currencies like Bitcoin, Ripple, and Etherium. Specific features unique to Emma Goldcoin include:

  • Using it doesn’t massively contribute to energy wastage and environmental damage.
  • It doesn’t increase the digital divide by helping early adopters at the expense of late adopters.
  • It’s entirely secure: it’s mathematically impossible to “steal”EGX.
  • Emma Goldcoin is so simple that you don’t even need a computer to use it: it “just works”.

Sure, it’s got its downsides, and I’d encourage you to read the specification if you’d like to learn more about what those are. Or if you already know what EGX is all about and just want to try a new way to manage your portfolio, give my new site EGXchange.org a go!

EGX fixes all the problems with all the existing cryptocurrencies once and for all. In particular it fixes the problems around security, environmental impact and ease of use that beset all other known blockchain-based cryptocurrency offerings.

  • Security

Due to the unique way in which the EGX blockchain is constructed, EGX cannot be hacked and will never be hacked. Period. There are and never will be any security issues with EGX. No other cryptocurrency on or off the planet can claim this.

  • Environment

Whether based on Proof Of Work or Proof of Stake, all other blockchains have a non-negligible and non-zero environmental impact. EGX however is based on neither of these. Instead it is based on Proof Of Existence, described below. PoE has a minimum environmental impact that is provably zero. Individual EGX implementations may have greater environmental impact than this, but that is entirely on the implementor. EGX PoE can be as low as zero if you wish, and we can prove this.

  • Ease Of Implementation

Due to its unique properties, no other cryptocurrency is or ever will be easier to implement and work with as EGX. This is not an empty claim – again, we can prove this.

Now here’s a cryptocurrency I can get behind. Shut up and take my money!

Not the first place I looked! Came out this way, this morning, to find the nearby 2021-12-22 51 -2 geohashpoint (it’s about two kilometres West of this GZ) and, during my return journey, noticed that this cache was close by. TFTC.

Plans

I’m going to be going half way here anyway on an errand. Might as well enjoy a morning hike and expand my Minesweeper grid, if I can.

Expedition

Given that I was driving half way from home to this hashpoint to run an errand anyway, I figured I might as well push the battery on the EV a little further. Coming over the graticule line would, if successful, expand my Minesweeper score, and as it’s such a beautiful frosty morning it seemed like great conditions for a bit of an explore.

I’d hoped to drive most of the way to the hashpoint and only walk a short distance, but I soon discovered that the nearest road is signposted as being for access to Syde Farm only (and is narrow enough that passing a vehicle coming the other way would be extremely awkward), so I parked up near geocache GC1WXE1 and hiked along a frozen bridleway to get closer to the hashpoint.

Reached the hashpoint around 10:15, turned around, and headed back, nabbing the geocache on the way. By the time I reached the car my hands were freezing and it was only as I returned my GPSr to my coat pocket that I remembered that I’d been carrying my gloves all along.

Taking a Jackbox Zoom Party to the Next Level

A love a good Jackbox Game. There’s nothing quite like sitting around the living room playing Drawful, Champ’d Up, Job Job, Trivia Murder Party, or Patently Stupid. But nowadays getting together in the same place isn’t as easy as it used to be, and as often as not I find my Jackbox gaming with friends or coworkers takes place over Zoom, Around, Google Meet or Discord.

There’s lots of guides to doing this – even an official one! – but they all miss a few pro tips that I think can turn a good party into a great party. Get all of this set up before your guests are due to arrive to make yourself look like a super-prepared digital party master.

1. Use two computers!

Two laptops: one showing a full-screen Zoom chat with Dan and "Jackbox Games"; the second showing a windowed copy of Jackbox Party Pack 8.
You can use more than two, but two should be considered the minimum for the host.

Using one computer for your video call and a second one to host the game (in addition to the device you’re using to play the games, which could be your phone) is really helpful for several reasons:

  • You can keep your video chat full-screen without the game window getting in the way, letting you spend more time focussed on your friends.
  • Your view of the main screen can be through the same screen-share that everybody else sees, helping you diagnose problems. It also means you experience similar video lag to everybody else, keeping things fair!
  • You can shunt the second computer into a breakout room, giving your guests the freedom to hop in and out of a “social” space and a “gaming” space at will. (You can even set up further computers and have multiple different “game rooms” running at the same time!)

2. Check the volume

Plugging an adapter into the headphone port tricks the computer into thinking some headphones are plugged in without actually needing the headphones quietly buzzing away on your desk.

Connect some headphones to the computer that’s running the game (or set up a virtual audio output device if you’re feeling more technical). This means you can still have the game play sounds and transmit them over Zoom, but you’ll only hear the sounds that come through the screen share, not the sounds that come through the second computer too.

That’s helpful, because (a) it means you don’t get feedback or have to put up with an echo at your end, and (b) it means you’ll be hearing the game exactly the same as your guests hear it, allowing you to easily tweak the volume to a level that allows for conversation over it.

3. Optimise the game settings

Jackbox games were designed first and foremost for sofa gaming, and playing with friends over the Internet benefits from a couple of changes to the default settings.

Sometimes the settings can be found in the main menu of a party pack, and sometimes they’re buried in the game itself, so do your research and know your way around before your party starts.

Turn the volume down, especially the volume of the music, so you can have a conversation over the game. I’d also recommend disabling Full-screen Mode: this reduces the resolution of the game, meaning there’s less data for your video-conferencing software to stream, and makes it easier to set up screen sharing without switching back and forth between your applications (see below).

Jackbox accessibility settings: Subtitles, Motion Sensitivity, and Extended Timers are turned on.
Turning on the Motion Sensitivity or Reduce Background Animations option if your game has it means there’ll be less movement in the background of the game. This can really help with the video compression used in videoconferencing software, meaning players on lower-speed connections are less-likely to experience lag or “blockiness” in busy scenes.

It’s worth considering turning Subtitles on so that guests can work out what word they missed (which for the trivia games can be a big deal). Depending on your group, Extended Timers is worth considering too: the lag introduced by videoconferencing can frustrate players who submit answers at the last second only to discover that – after transmission delays – they missed the window! Extended Timers don’t solve that, but they do mean that such players are less-likely to end up waiting to the last second in the first place.

Jackbox game content settings; "Filter US-centric content" is switched on.
Finally: unless the vast majority or all of your guests are in the USA, you might like to flip the Filter US-Centric Content switch so that you don’t get a bunch of people scratching their heads over a cultural reference that they just don’t get.

By the way, you can use your cursor keys and enter to operate Jackbox games menus, which is usually easier than fiddling with a mouse.

4. Optimise Zoom’s settings

A few quick tweaks to your settings can make all the difference to how great the game looks.

Whatever videoconferencing platform you’re using, the settings for screen sharing are usually broadly similar. I suggest:

  • Make sure you’ve ticked “Share sound” or a similar setting that broadcasts the game’s audio: in some games, this is crucial; in others, it’s nice-to-have. Use your other computer to test how it sounds and tweak the volume accordingly.
  • Check “Optimize for video clip”; this hints to your videoconferencing software that all parts of the content could be moving at once so it can use the same kind of codec it would for sending video of your face. The alternative assumes that most of the screen will stay static (because it’s the desktop, the background of your slides, or whatever), which works better with a different kind of codec.
  • Use “Portion of Screen” sharing rather than selecting the application. This ensures that you can select just the parts of the application that have content in, and not “black bars”, window chrome and the like, which looks more-professional as well as sending less data over the connection.
  • If your platform allows it, consider making the mouse cursor invisible in the shared content: this means that you won’t end up with an annoying cursor sitting in the middle of the screen and getting in the way of text, and makes menu operation look slicker if you end up using the mouse instead of the keyboard for some reason.

Don’t forget to shut down any software that might “pop up” notifications: chat applications, your email client, etc.: the last thing you want is somebody to send you a naughty picture over WhatsApp and the desktop client to show it to everybody else in your party!

Dan Q found GC5VKVN Walk by the Firehouse #4

This checkin to GC5VKVN Walk by the Firehouse #4 reflects a geocaching.com log entry. See more of Dan's cache logs.

I first tried to find this cache back in 2018, but the cache container had been destroyed leaving only a fragment of it left. Today, as I was out on a lunchtime cycle nearby anyway, I decided to come and give it another go. I’d left my primary GPSr at home so I had to use my phone, which for some reason was declaring my position to be about 22m off target (and well into the fields, based on local aerial photography!) but my memory of the hiding place – coupled with a quick check of the clue – confirmed I was looking in the right place. I don’t know if it’s hidden higher up now or if I’ve just gotten shorter but it was a bit of a stretch to reach! SL, TFTC.

Dan Q couldn’t find GC9K2D0 The Footpath Wonder

Saw the notification pop up and thought this was an obvious FTF opportunity, so me and a geokid zipped out and mounted a search. After about 20 minutes of hunting we double checked hint cache details – only a D2/T1: maybe we’re not on form today. Or maybe something else is amiss: a brand new cache by a cacher with no finds and no (other) hides, with no description and no hint? Did this perhaps get published prematurely? We’ll come back later in the week for another go, but for now this one’s a sad-face for us.

Geosense sent me straight to this one during a short visit to Stratford. Some fellow volunteers and I stayed at the hotel last night for our AGM and Christmas party and I couldn’t resist coming out to find this before heading back to Oxfordshire. TFTC.

Tick Tock

Looking for something with an “escape room” vibe for our date night this week, Ruth and I tried Tick Tock: A Tale for Two, a multiplayer simultaneous cooperative play game for two people, produced by Other Tales Interactive. It was amazing and I’d highly recommend it.

Tick Tock screenshot showing a mysterious machine with many buttons. The machine is switched on and the screen shows a wolf's head and the number "-2". The buttons show a bug, an hourglass, a snake, a wolf's head, a keyhole, a cog, a raven, a doll, and a section of railway track.
If you enjoyed the puzzles of Myst but you only want to spend about an hour, not the rest of your life, solving then, this might be the game for you.

The game’s available on a variety of platforms: Windows, Mac, Android, iOS, and Nintendo Switch. We opted for the Android version because, thanks to Google Play Family Library, this meant we only had to buy one copy  (you need it installed on both devices you’re playing it on, although both devices don’t have to be of the same type: you could use an iPhone and a Nintendo Switch for example).

Screenshot from Tick Tock: an old-fashioned wireless radio set produces a scramble of letters in the air.
I can’t read that text. But if I could, it still wouldn’t make much sense without my partner’s input.

The really clever bit from a technical perspective is that the two devices don’t communicate with one another. You could put your devices in flight mode and this game would still work just fine! Instead, the gameplay functions by, at any given time, giving you either (a) a puzzle for which the other person’s device will provide the solution, or (b) a puzzle that you both share, but for which each device only gives you half of the clues you need. By working as a team and communicating effectively (think Keep Talking and Nobody Explodes but without the time pressure), you and your partner will solve the puzzles and progress the plot.

(We’re purists for this kind of puzzle game so we didn’t look at one another’s screens, but I can see how it’d be tempting to “cheat” in this way, especially given that even the guys in the trailer do so!)

You could probably play successfully without keeping notes, but we opted to grab a pad and pen at one point.

The puzzles start easy enough, to the extent that we were worried that the entire experience might not be challenging for us. But the second of the three acts proved us wrong and we had to step up our communication and coordination, and the final act had one puzzle that had us scratching our heads for some time! Quite an enjoyable difficulty curve, but still balanced to make sure that we got to a solution, together, in the end. That’s a hard thing to achieve in a game, and deserves praise.

Tick Tock screenshot: among other documents, we examine a schematic for the construction of a mechanical raven's wing.
The art style and user interface is simple and intuitive, leaving you to focus on the puzzles.

The plot is a little abstract at times and it’s hard to work out exactly what role we, the protagonists, play until right at the end. That’s a bit of a shame, but not in itself a reason to reject this wonderful gem of a game. We spent 72 minutes playing it, although that includes a break in the middle to eat a delivery curry.

If you’re looking for something a bit different for a quiet night in with somebody special, it’s well worth a look.
