<p>Try a prompt that helps claude iterate until it can verify the result.<p>For example, if you tell it to compile and run tests, you should never be in a situation with syntax errors.<p>But if you don’t give a prompt that allows to validate the result, then it’s going to get you whatever.</p>

<p>A couple suggestions:<p>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).<p>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.<p>In summary, just focus on what people want to see at a glance and make it easier for them.<p>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.

<p>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.</p>

<p>> To fund development for this critical next stage, we will launch a crowdfunding campaign on a platform such as Indiegogo or Kickstarter.<p>Great point. I highly recommend crowdsupply for this type of project (extremely technical target customers), especially if this is the first campaign you run, as their team is helping much more on the nuances of running a successful campaign.<p>(I know this is not the place for ads, and I’m not affiliated though I run crowdfunding campaigns on all the platforms mentioned.)</p>

<p>You could run a Solana validator. Here's a calculator if you want to get a sense of the potential revenue:
<a href="https://www.aeropool.io/validatorprofitcalculator" rel="nofollow">https://www.aeropool.io/validatorprofitcalculator</a><p>Bare in mind:<p>- bandwidth will be high, say 20-25 TB/mo outgoing<p>- ram you might be tight, if you have the chance to grow to 384-512 it'd prob be better<p>- you'll need at least 2 boxes, one for mainnet and one for testnet. Testnet will be "less important" so you can still run a lot of other things on that machine<p>If I were you, assuming you find this interesting, I'd start a testnet node on your current machine, get practice with it, as I was mentioning keep running your other services. And then if you're convinced you just rent a 2nd machine on any of existing providers/your favorite location to run mainnet.</p>

<p>I don’t get the sentiment of the article.<p>The whole point about passkeys is to replicate the exact UX of passwords (registration, reset…) but offer protection against phishing, by using public key crypto.<p>If you want a different UX, use a hardware security key. But these failed to reach consumer adoption.<p>And of course the FIDO2 standard didn’t specify (yet) a way to move passkeys around, so each implementation chose their own way to do vendor lock in. But this will be fixed in a few iterations.</p>

<p>Sorry maybe I should have been more specific. I had Unitree in mind, last time I checked the humanoid with no hands was $20k and each hand was an extra $20k. Yours seems to ship with 2 hands for extra $1k (surprisingly cheap, which is great of course!). I was curious to read more about what the hands are capable of doing.</p>
