The anti🚫-derailment🚃 & thread🧵 hijacking🔫 thread🧵 ⁉

There’s this thing in Finland called “vehicle decommissioning”. I really love it!

What that is is, you pay 5.40 EUR to take your vehicle off the road temporarily (but as long as you want). It’s a flat fee, and after you’ve paid you stop paying tax and insurance, until you put it back on the road. That’s done on their website and it takes 10 minutes. If you need your car, one click, and hey-presto, you’re back on the road 10 minutes later.

It’s brilliant for people like me who don’t drive very much: normally car TCO is about 10 EUR per day for me, whether I drive the car or not. That’s what it costs me to own a car and use it infrequently in any other country. But here, I just decommission it, and I can have the luxury of owning a car without bleeding money when I don’t need it.

It’s great because it doesn’t penalize those who strive to be as car-free as possible but don’t have the option of going all the way, and it incentivizes people to drive less. Just what the world needs!

So once again, yeah Finland :slight_smile:


So there was a APP for the forum, right?

Can someone send me the link?

It isn’t really an app so much on Android as a shortcut directly to the forum in a “dedicated” browser window.

Lol OK


Then i dont need it :slight_smile:

Hi everyone,

I was scrolling into the chat finding some interesting argument to read about and then I found the post of Yeka, so I decided to reply and write for the first time on the DT forum.

My name is Francesco, I am Italian, 29 years old and I am the ceo of a small Italian start-up named Novemm.

Novemm is the result of a partnership with VivoKey (as enabling technology partner/OEM) that allow Novemm to offer private label Apex wearables, bracelet and ring, aimed exclusively at B2B customers, primarily banks but possibly also fintechs, cryptoexchanges, DeFi wallet and other 3rd party providers.

Actually Apex bracelet is in the public beta product stage and it will be released soon either on the B2C (sold by VivoKey) and B2B (sold by Novemm) market, but unfortunately at the moment there’s no official time to market for the Apex bracelet and Apex ring (either B2B and B2C) and anyway we’ll officially launch on the market Apex B2B project only when Apex B2C wearables will be realased on the market, and you know well theese are informations that only our Lord commander knows :slight_smile:

One of the main Novemm long term goal is supporting important DeFi wallet projects to bring on the market real crypto wallet payments in POS and mobile contactless transactions.

Actual crypto cards (as the Binance one) are a fake trivial attempt to the blockchain meaning and values, because those cards don’t run any bitcoin/ethereum/etc… wallet applet.

We also hope to integrate soon VivoKey APIs with some important DeFi project like Bitcoin or Ethereum forks to authorize mobile access and transactions; and maybe an Apex branded wearable could convince them :slight_smile:

There is some company going into this whit real crypto cards, as the long dead project of Fidesmo unplugged, Arculus or Sugi Wallet, bit I’m sure a bracelet/ring hardware wallet form factor could be interesting to experiment for mobile app DeFi wallet projects.

When it comes to B2B project now it’s time for banks the but here is where it comes a Basic level, unless banks integrate also VivoKey APIs to offer Strong Customer Authentication through private label Apex wearables (and not only Fidesmo APIs to connect the tokenization service to offer tokenized payments through Apex wearables).

The banking and DeFi space are for sure fields where B2B Apex wearables can represent a game-changer device, either for technology and form factor.

This was a deserved short introduction for the DT community forum.

More details about the B2B project will be given in the next months.

Thanks for support guys, stay tuned.


Really off topic, but that’s the thread, right?

Let me preface this by saying I may be the most musically illiterate person you’ll ever know. I had to look up a c-major cord, but first I had to look up a chord, so go easy at me.

I’m looking to make a xylophone as part of a larger project. I’m planning to cut larger diameter pipe, (2 to 2.5 inch diameter) according to the math found HERE.

My question is, what effect does the thickness of the pipe, and / or the material of the pipe (copper, steel, aluminum) have on it’s sound?

Also, would the mounting points used to support each pipe have an effect on sound if moved closer to, or further from the ends of the pipe?

The thickness and material I do not know. Where to mount however is a pretty big thing for how it will sound. look at how the bars are mounted in a standard xylophone or marimba they should give you a solid indication of where to mount the pipes for the best sound.

I have little to no musical ability, but I could take a shitty material property guess that for a set material, a thicker wall would be stiffer and result in less flexibility

I think flex is good for what you want as it would soften the bounce down the tube giving a more uniform tone?

Or alternatively it could absorb some of the vibrations and reduce your volume…

I’m no expert, but here’s how I understand it
Thickness of the pipe would likely affect volume, or how hard you have to whack it to make a certain volume, as well as how long the note was sustained.
Mounting points would likely also change how long the note was sustained, the more rigidly mounted it is, the shorter it’ll vibrate.
The actual tone is mostly determined by the standing waves in the pipe, which is determined by length. Unless they’re weird pipes and then you could get a bit of the helmholtz resonance that throws things off. In general, I believe the main wavelength in a pipe is roughly 2x the length of said pipe

I’ve spent way to much time trying to accurately determine the height of water bottles from the frequency of the tone they produce when you blow over the top to make that humming noise, and that’s what I understand so far

I don’t know much on the math of this but I did play xylophone for 4 years.
As others have mentioned the mounting point and distance from key makes a huge difference you dont want then to be too rigid or too loose, too far away from the keys or aluminum.
As for the resonators (your pipes) material I wouldn’t recommend using anything other than copper or aluminium. Aluminum is obviously more common because it’s cheaper.
As for the materials of the keys Rosewood is best.

If you’re going for more of a Glockenspiel instead (which would be easier if it fits your project) you can make the keys of steel bars.

Just wanted to mention, if you want to listen to a great album full of bells, you’ll enjoy this very much:


White russians are great!!
(Bloody hell… out of context this sentence is terrible!!! Think that drink just got an extra reason why to love it)

Lager beer is an acquired taste.
IPA beer is a hipster’s bad joke.

Maybe you’ll like some smooth Wheat beers. Those are nice as a hearthy meal drink.
Thinking of Belgian stuff, fruity Allembic beers are also great! (but you need to find a good brand. there are some great ones which you might like, but there are some terrible ones as well)

Now, Porter and Imperial stout… Now we’re talking! Perfect end-of-a-long-day beer.

Although I’m myself a whiskey person, I wouldn’t reccommend to you given your description.

That’s a classic!!

And that, my sir, earned my respect!! XD

I used to do the Alien Brainmorrhage with Baileys, Curacao blue, vodka, cherry liquor and a tiny bit of absynth.
Did not improve the taste, but did gave the kicks to anyone!! XD

And since we’re on recipes…
For a while I served my “breakfast” off-the-menu signature cocktail:
“Barney’s Gran-Grandma Irish Coffee”:
4 shots of Baileys
1 shot of Amaretto
2 shots of Irish non-smokey whiskey
2 shots of coffee liquor (I can’t reccomend enough Mr Black)

Then you add in Cream, sugar and expresso… all at the Ideal ratio of 0% (zero%), and have an Explendid morning!!


I found Xylophone math!

Basically the different materials are calculated off of their speed of sound through said material. Makes sense. The ID and OD are calculated as well.

The mount points and length were the most interesting to me. The length of the tube is (more or less) 2x the length of the sound wave. When a tube is struck, it flexes down in the middle, and up at the ends, then rebounds to up / down, then back and forth, right? the point where the tube is essentialy staying still in the up/down - down/up transition (pivot point) is where you want to mount it.


I had an interesting conversation with a guy at the bar: the guy told me how great implants must be if you have some data to hide from the authorities, like the list of your offshore bank accounts, your bitcoin address’ private key or the decryption key to a hard-drive with hot stuff on it.

I told him implants would just be a convenience to carry the hot data around, but you’d still want the data encrypted (or held into a passworded section of the implant) and then you run into the problem of being legally obliged to supply the password, or look guilty as hell if you don’t, etc.

The guy said “They can’t force you to decrypt something they don’t know about. Who’s gonna tell them you have an implant with hot data on it if you don’t? I can’t tell you have some even if I look at your hands very carefully, and I only feel them because I’m looking for them.”

Interesting… I know the authorities can search you pretty thoroughly, including searching for stuff on you or in you, with rubber gloves or with x-rays in some situations, and with probable cause for doing it. Like if you’re likely to smuggle a weapon in prison, or customs suspects you swallowed baggies of drugs on that flight from Bogotá you’ve just disembarked from, then that might happen.

But what if you’re arrested for tax fraud? Or as part of a crime investigation? They’re not going to x-ray your entire body are they? And if they did, a flex is almost invisible. They might find something if they palpate your entire body very carefully inch by inch. But how likely is that? And even then, I myself have trouble finding my own xBT in my chest that way, nevermind someone who doesn’t even know it’s there.

I’m thinking, for the authorities to find an implant on you and start wondering what it might contain, they’d really have to know you’re into implants and suspect you might have used one to hide stuff. Otherwise, my drinking buddy is probably right: nobody’s gonna happen upon one of your implant as part of a regular search, and if they did, know what it is and try to read it, if you keep your trap shut.

I’ve never been x-rayed on a flight from bogota… But it’s worth noting that I’m not a criminal and don’t smuggle shit.

Is security through obscurity

It’ll probably work, till it doesn’t

The more and more eroded bodily rights get, won’t surprise me when they cut an implant out as “potential” evidence of something
