operator-name··on Tor Release 0.4.8.1-Alpha Includes Onion Service Proof-of-Work
0.4.8.3-rc released 5 days ago, and 0.4.8 stable is set to release in the coming week or so.

I've not looked at the specific implementation here, but Tor's implementation[0] includes a dynamic difficulty scaling.

When under attack, legitimate users will experience a moderate delay whilst attackers will need to scale their compute.

operator-name··on The infamous coin toss
I think I've reached an understanding, but do correct me if I'm wrong.

    lim players -> inf
    mean wealth -> starting_wealth * (win_chance * (1 + win_gain) + lose_chance * (1 - lose_loss)^rounds)
So in their example case

    win_change = lose_change = 0.5
    win_gain = 1.5
    lose_loss = 0.4
    (0.5 * (1 + 0.5) + 0.5 * (1 - 0.4)) = 1.05
so on average the mean wealth increases as the number of rounds increases. Yet at the same time for a single player

    lim rounds -> inf
    wealth -> 0
As others have mentioned, this is because the win multiplier is 1 + win_gain = 1.5 whereas the loss multiplier is 1 - lose_loss = 0.6. This is more easily seen by comparing the log of the multiplier

ln(1.5) = 0.41 ln(0.6) = -0.51

For the game to be profitable, it must satisfy

ln(1 + win_gain) > -ln(1 - lose_loss) <=> 1 + win_gain > 1/(1 - lose_loss)

So for a gain of 50% the loss must be less than 33.3%.

For some reason this is not mentioned in the article but is mentioned in the video.

If you're starting this on a mobile device, don't make the same mistake I did. It gets quite laggy later on and some of the "gameplay elements" are designed around having a mouse.

MBD definitely sounds like it was recorded in dead room, whereas plain EnCodec has been mixed but includes some artificial noise.

Sadly looks unlikely if the base model wasn't trained on vocals.

> Mitigations: Vocals have been removed from the data source using corresponding tags, and then using a state-of-the-art music source separation method, namely using the open source Hybrid Transformer for Music Source Separation (HT-Demucs).

> Limitations: The model is not able to generate realistic vocals.

(https://github.com/facebookresearch/audiocraft/blob/main/mod...)

I suspect this was a combination of playing it safe and that the model isn't well architected to reproduce meaningful vocals.

And https://audiocraft.metademolab.com/musicgen.html

The samples included in the press release are quite impressive to my ears, but the other samples (especially from AudioGen) have a hint of artificially.

As usual the music is quite repetitive, but I'm looking forward to tools that simplify changing the prompt whilst it generates over a window. I can only imagine the consequences for royalty free music.

Edit: the "Text-to-music generation with diffusion-based EnCodec" samples are quite impressive.

Is it not the data that is the problem rather than the tool?

That's a cool series, thanks for sharing!

I didn't grow up during this era, so it was facinating to stumble upon a news article on the (lack of continued) funding for BSD - something I'd never really thought about.

Another great one is Kirby Reanimated: https://youtu.be/U_JzkjbuQjU

The original episode explores how animation is made by having the characters remake the first episode, so it's doubly meta that the fans have reanimated it.

operator-name··on Wayland on NixOS: Confusion, Conquest, Triumph
I've really enjoyed your articles so far.

This one took a bit of a turn - by the middle you mention that major DEs support Wayland then suddenly transition into disabling XFCE and installing Sway?

It would useful to clarify your audience at the start, and make mention that by default Gnome and KDE already automatically use Wayland if compatible (lady I checked).

Haha, I guess that works too. Does the screen rotate, or you you?

I'd be cautious about stuff like this - if you annoy the wrong person that could paint a target on your back.

I don't think so. Some of the 3 or 4 puzzles require rotation and cris crossing

This is pretty fun! It seems the starting position of your fingers is important, as is the ability to rotate the device. Interesting to see how many mobile HN users there are too.
