I recently added ml-dsa-44 to solokeys, both piv and fido2. To my understanding ssh+fido2 doesn’t support pq yet, but if anybody’s reading and knows how to make it happen, I’d be really interested.

I think I found a mini bug. Say I do a score of 10. Then I change board. Then I die with score < 10. I still have 10 for that board. It makes it easy to cheat the leaderboard :) Fun game!

For firmware dev, Claude is amazing. Just plug the dev board and tell him what you need. Great learning tool too!

I’m surprised that the Seeker is not even mentioned. I understand it’s Solana, it’s blockchain, whatever people think about it... to me it’s the only serious attempt at creating an app store that can compete with apple or google. What’s the point of independent hardware if the whole sw stack is them?

Same. To add some details, I used Authy because at the time it was the only app that would just work after upgrading my iphone. I never enabled their cloud mode, so only local 2FA codes.

I’m very familiar, we made Somu :) I meant USB-C.

I dream of an open board like the yubikey nano. This is very nice!

Try a prompt that helps claude iterate until it can verify the result.

For example, if you tell it to compile and run tests, you should never be in a situation with syntax errors.

But if you don’t give a prompt that allows to validate the result, then it’s going to get you whatever.

Has anyone tried to "turn off some cores" (eg using multi-instance gpu feature) and see if/how that increases reliability?

If you have the opportunity, try out a zen5. Significant improvements.

It’s explained in the link. I actually misremembered, it’s 196 bits.

Cool demo, but this is only log2(43 quintillions) = 65 bit security.

Kind of related is DiceKeys, with 192 bit security: https://www.crowdsupply.com/dicekeys/dicekeys

Link to Vitalik's post would be preferable, context is important.

A couple suggestions:

1. Pay attention to the first 2-3 columns, the ones the user immediately sees. E.g. short or hidden id, short but readable name, useful next column (e.g. sales or views or whatever is the most useful data).

2. Put columns that need to be evaluated together close to each other. On desktop it's easy to see 2 numbers even if there's a column in the middle, on mobile it may require scrolling horizontally.

In summary, just focus on what people want to see at a glance and make it easier for them.

I'm just a user suffering the pain, this is an example of a table I need/want to monitor and it's very poorly done, I need total revenue = sum of column 5 + 7, on mobile it's a very bad experience due to column 6 in the middle, unnecessary width of some columns with repeated text, etc. https://app.vx.tools/income/BfgMdL4FaNHp5zZpD7WMYG5sZUrCWQPE...

There’s a picture at the bottom. I think the text there is a bit more clear (maybe?): you have a cubic surface and want to see if there’s any “straight line” that lives/lies on the surface. It turns out there’s 27 lol.

It looks like they have examples with unreliable channels: https://github.com/n0-computer/iroh/tree/main/iroh/examples

You'll prob have to check the max packet size that you want to forward because quic adds a bit of overhead.
