What's it called?

2024-08-19 21:59:09

A new version of Bisq2 came out with some nice features, namely Lightning support and QR code scanning. But regarding the later...
The QR code scanning is a separate bundled Java app with a bunch of binary code. To be precise, there are 76 shared libraries which would have to be patchelf-ed to get QR code scanning to work on NixOS. Either that, or I'll have to run the webcam app in a container. Either way, that's still 76 libraries for which I'd have to identify dependencies, find their matching packages in Nixpkgs, and hope for the best. Not to mention the amount of churn I'd have to put my new-ish SSD through to build, build, and rebuild, until it works. I had plenty of difficulty getting QR code scanning to work on Sparrow, and that was child's play compared to what I'm looking at with Bisq2. About 4 years ago when I packaged Bisq1 I destroyed my SSD in the process, so I'm mindful about these things.
So, you know what I'm thinking...
I have no plans to fix Bisq2 QR code scanning. Sorry, but either it will remain broken or another brave soul can take a stab at it.

Here's a goofy thought:
Given a "God candle" is a big-ass bullish candle in the Bitcoin spot market, doesn't that mean that a big-ass bearish candle should be named a "Satan candle"?
I know, it's stupid. But I needed the laugh to get our damn parasitic USG out of my mind.

Yes, Hyprland is a "Wayland compositor" so it uses the Wayland protocol.
There are various (and very few) implementations of the Wayland protocol. GNOME's implementation is Mutter, and Hyprland *was* based on wlroots; Hyprland is now migrating to their own Wayland implementation.

My objective with Nim is to use it as a replacement for C++, so that the compiler can do more of the heavy lifting; Algebraic Data Types, anyone?
For work I create DLLs (plugins) which must be able to utilize a C++ ABI.
Many programming languages can interact with a C ABI using a FFI, but that's not the case with a C++ ABI.
But perhaps Nim can be my cheat code, given it can produce C++ code :)

I've been dipping my toes into Hyprland.
I'm a 20+ year X11 junkie, so this is all new territory.
I wasn't planning on doing this so soon, but the dual-monitor situation with Xorg and AMD/NVIDIA hybrid graphics is... clunky. It works, but only as long as I don't try to modify the monitors after they have been set. I get one shot to use xrandr when I log in. If I run it a second time... POOF... there goes Xorg.
I was curious about how it would work on Hyprland, and... it just worked! Both monitors came right up, and I could rotate one of them without anything crashing.

If there's enough distaste for it such that it would be political suicide to attempt a CBDC, then we might skip it.
But I'm not convinced we are there yet. There's still an abundace of deep-seated fuckery going on in the USG.
Sometimes adoption of totalitarian policies are not skipped but rather delayed until there's a better climate for it.
If a CBDC gets skipped this time around, and Bitcoin becomes well entrenched, then there's a much better chance that a CBDC won't happen at all.
But it really depends on how much of this totalitarian bullshit US citizens are able to squash out of existence.

Back in February I had the strangest, yet perhaps the most impactful Astral Projection experience.
This certainly wasn't my favorite experience. Not even close! But it's one that has left a mark because of what it means personally, (which took a few days to figure out) and because it contained one specific word.
It started with me laying on my bed while being in that weird, incomprehensible dream state wherein nothing makes sense. But an unusual thought came to mind: "I'll show you the way."
What the heck. I don't think of phrases like that. But the moment I did I felt my bed lift up into the air. It was wobbly as you'd expect, and the damn thing launched into full flight, like I was on a roller-coaster. Yes, with me still laying on my bed.
That's when I realized an Astral Projection had begun. So I calmly waited to see what would happen. It's very easy to freak out and break the experience.
Everything went white, but I could still feel the awesome flying sensation. Then I thought: "Where are we going?"
That thought kicked off a voice which sounded like Morgan Freeman making an announcement over a megaphone. The voice said this:
"So you think, Emmanuel, that you're going to be really good at one thing or another... well those things don't matter. Follow the way of love."
Then BOOM, the whole thing was over in an instant.
I've never before heard my name during an Astral Projection. So that shocked me. And I did find the message rather insulting, but like it said, it made sense a few days later.
A few months have passed, and I'm still a bit shocked by all of this.

You can use the Boltz exchange: https://boltz.exchange/
But, be mindful of the BTC on-chain fees. With Boltz you'd pay for a high-priority confirmation; The highest fees.
Another option is to swap "Lightning BTC" for Liquid BTC, which you can also do on the Boltz exchange. For this you need Liquid wallet to receive the funds. Then, you "peg-out" of Liquid BTC to "on-chain BTC". This can be a lower-fee option because the Lightning -> Liquid swap is cheap, and the Liquid "peg-out" using sideswap.io allows you to set a priority for the BTC transaction. Therefore, if you can afford to wait, this two-step process can save some sats.

Hopefully y'all took advantage of the 10 sat/vbyte mempool fees last night!
That opportunity is now gone, once again.
"Oh, I already have a mobile Lightning wallet." you say?
OK, but where's your Lightning desktop wallet? Are you really going to pay all your monthly bills from your phone? Of course, if you have a Windows PC then hell no, don't get a Lightning desktop wallet!
It was also a good opportunity for L-BTC swaps.
Or UTXO consolidation.
But the thing is, you gotta know what you need to do before hand and be ready, so that when the fees are favorable you can just jump in and do it.
I don't even know why I'm typing this LOLz! Perhaps I'm in an unusually chatty mood. Imagine the craziness that would come out of my keyboard if I was an alchoholic :)

Yesterday I defeated the first two Colossusi in "Shadow of the Colossus" (https://en.wikipedia.org/wiki/Shadow_of_the_Colossus). The Playstation 2 version.
Today, I'm exhausted from defeating just the third one. Phew! I think I spent about one or two hours on it.
Mounting the Colossus was simple enough, but staying on was tough! I kept falling off, over and over again.
When the Colossus starts trying to shake me off, it seems to depleat my stamina much quicker than usual, making it even harder to stay on.
Fun game.

Note: There's a bug in my Bisq 2 Nix package.
The symptom is an immediate failure to connect to the Tor network, and it can happen after updating Nixpkgs.
The cause is that once Bisq 2 extracts the Tor binary (BASH script) from it's JAR archive, it doesn't extract it again; At least for the same version of Bisq 2. This can lead to the extracted scripting pointing to a Tor binary that's no longer in the Nix store.
I fixed it by deleting the directory where Tor is extracted, so that Bisq 2 has to extract upon every start up.

One neat Linux-compatible application which I don't think I've mentioned before is Tiddly Desktop.
Tiddly Desktop (https://github.com/TiddlyWiki/TiddlyDesktop) is a desktop application for Tiddly Wiki, a personal wiki as a single-page-application.
Being a SPA, Tiddly Wiki (https://tiddlywiki.com/) works just fine in a web browser, but saving your wiki is weird because you effectively have to download an updated copy of the Wiki. Then you manually replace the HTML file. It works, but it's cumbersome.
Tiddly Desktop is basically a wrapper around Tiddly Wiki, and it improves the saving functionality so that saving your wiki is seamless.
For Linux users, Tiddly Desktop comes as a downloadable Tarball which you then extract and execute the nwjs binary within. But, if you run NixOS... you're in luck because running Tiddly Desktop is as easy as:
$ nix run github:TiddlyWiki/TiddlyDesktop
If it doesn't work, it's my fault! For what it's worth, I've been using the Nix flake for 2+ years without issues. I update the Nixpkgs flake input when there's a new NixOS release.
If you're shopping for a note-taking app, a personal knowledge base, or even a JavaScript-based environment you can write apps in a similar fashion to Smalltalk images, I think it's worth taking a look at Tiddly Wiki and Tiddly Desktop.

Yep.
If I or any other citizen were to get into crazy unpayable debt like that, our credibity would be ruined.
But when US Gov. does it, it's just a mere news headline.

I recently had a dream that I was Darth Vader. LOL! It was super weird.

I started with QBASIC.
Later, while at school I modified the QBASIC snake game to add cheat codes. Infinite lives, go right through walls, etc.
Those were the days.

That poor guy is going to have nightmares. He'll never look at horses the same way.

A desirable feature of Bitcoin-related applications is to be able to verify the downloaded installer/package. This is a bit problematic on NixOS because the package manager downloads the application, not the user.
As a first step in being able to verify Bisq2 on NixOS, I implemented reproduceable build-time verification. In essence, the Nix derivation uses GPG to verify upstream's Debian package, before unpacking the .dep file; If the verification fails then the entire build fails. A failure looks like this:
https://image.nostr.build/4fef6437772d85e70c509b5ee9c11cf5db30fa2f14df57a57a905d4103ecc5d3.jpg
In the example above, I simply replaced the correct public key (which is contained in the erosanix repo for reproduceability) with my own to cause an intentional failure.
The end result is that the end-user can have limited confirmation that if Bisq2 installs, then the installation is verified.
I believe this form of verification is superior to what I had done before, which is to automatically or manually verify the .deb; In this form, the end user has absolutely no confirmation that the .deb file has been verified.
I say "limited confirmation" because this doesn't completely absolve the user's responsibility to verify the download. For example, a malicious actor can replace the public key and source files that are in the repo. I haven't fully developed the end-user verification process, but I think it could be something like this:
1. Audit the Nix expression to understand that in fact the .dep package is being verified and no funny business is happening.
2. Compare the public key that's in the repo with the one on the Bisq website to confirm they are the same.
3. To make the process quicker in the future, use your own GPG key to create external signatures for the public key (in the repo) and the Nix expression.
I'd have to modify the Nix expression a bit, but the idea is that once the code has been audited and signed, future verification can be done quickly by verifying the Nix expression and public key with the signatures. To make this work I need to store the Bisq2 version and the SHA256 checksums in a separate Nix file.
