codethief··on Why Japan has such good railways
> Not to mention that every few years either a typhoon or a 9.0 earthquake defeats any effort to build exceptional value in your property.

Isn't that the same in certain regions of the US?

> > Why are you handwaving things away though? I've got you on max effort. I even patched the system prompts to reduce this.

In my experience, prompts like this one, which 1) ask for a reason behind an answer (when the model won't actually be able to provide one), 2) are somewhat standoff-ish, don't work well at all. You'll just have the model go the other way.

What works much better is to tell the model to take a step back and re-evaluate. Sometimes it also helps to explicitly ask it to look at things from a different angle XYZ, in other words, to add some entropy to get it away from the local optimum it's currently at.

Interesting link! What was the solution? How did they end up redesigning the cockpit?
codethief··on Claude Opus 4.7
Hasn't happened to me, either, but this GitHub comment is reporting similar observations: https://github.com/anthropics/claude-code/issues/42796#issue...
codethief··on German Dog Commands
There are many cases where people use it and the dog does not have anything in their mouth.
codethief··on IPv6 traffic crosses the 50% mark
At least HN supports IPv6 now, which I remember was not the case last time I checked.

> 2. Drop it / Let go — Aus. In German, aus is a preposition meaning “out of.”

It also means "off" and – in sports – "offside", which I think is much closer to what "aus" means in this context.

codethief··on I made a terminal pager
+1 I actually came here hoping that OP had built a better `less`. Along with refresh, I'd also love to see mouse compatibility (scrolling etc.) and better performance when reading huge files.

> This implies the only content with moral worth are those that teach knowledge or skills

This is not what OP said. He was talking about the "moral goodness of providing access to X, despite it being illlegal. He never said anything about the moral worth of X itself, let alone that Y had no moral worth.

> AA is providing a valuable service to tons of people who don't have access to these books otherwise. There's a strong argument to be made for the moral goodness of that -- that even if it's illegal, it's at least in the spirit of a public library.

codethief··on YouTube now lets you turn off Shorts
I use Newsfeed Eradicator[0] to block shorts and many more things.

codethief··on Claude Code Routines
Weird, I've been using Claude Code w/ Opus 4.5/4.6 for Python programming the last couple months and I rarely see the issues you mentioned.
codethief··on GitHub Stacked PRs
Anything from iriver.
codethief··on Cirrus Labs to join OpenAI
AFAIU Dagger is moving away from Docker, too. They're working on their own container engine in order to be able to improve caching.

I'm not following?
codethief··on Android now stops you sharing your location in photos
Personal notes, and tons of academic papers and ebooks, all of which might contain question marks and colons. Occasionally, I also use arrows -> in travel itineraries / ticket PDFs.
codethief··on Android now stops you sharing your location in photos
In a similar move (silently changing a feature crucial to some users), in Android 11 Google suddenly removed the possibility to use "special" characters

  ":<>?|\*
in filenames[0], presumably because they're not allowed on Windows/NTFS and Windows users might end up struggling to transfer them to their Windows computer. I don't care about NTFS at all, though. I just want to be able to sync all my files with my Linux machines and now I'm no longer able to. Makes me want to scream.

codethief··on Tofolli gates are all you need
Yes, I think that's a stance many physicists take these days. Unfortunately, it's not verifiable. And we also don't have any clue how gravity (which does become relevant at our scales) would fit into this picture.
codethief··on Tofolli gates are all you need
On the topic of scaling, reversible computations are more energy efficient than non-reversible ones, see also the OP. Outputting the original inputs might seem silly and wasteful superficially but if you discarded them (as "heat"), you'd just be back to building a non-reversible, likely much less efficient gate.
codethief··on Tofolli gates are all you need
> Actually this is true whichever interpretation you take

In the Copenhagen interpretation the collapse of the wave function explicitly violates unitarity (and thus reversibility).

codethief··on Cirrus Labs to join OpenAI
> I wrote a blogpost about it [0]

Having tried many other CI systems, all of which ultimately turned out to be subpar, it makes me incredibly sad to discover only now that Cirrus CI is (was?) quite a bit better than them. :( Thanks for the blog post, though!

codethief··on Open Source Security at Astral
Shouldn't you always read & double-check the 3rd-party GitHub actions you use, anyway? (Forking or copying their code alone doesn't solve the issue you mention any more than pinning a SHA does.)
codethief··on Show HN: Is Hormuz open yet?
You could get in touch with GP by googling for his company (see profile), finding his name through the company website (he's the CEO), and then googling for his LinkedIn/X accounts.

Also: Cool project!

codethief··on Škoda DuoBell: A bicycle bell that penetrates noise-cancelling headphones
I would love that but not so much for pedestrians as for cars that don't see me on my bike. Ideally, the "bell" would automatically honk at them very loudly when they get too close.

So where can I buy this thing?
codethief··on A cryptography engineer's perspective on quantum computing timelines
Agreed, I never put much trust in Intel SGX, either. I was bringing up the whole topic rather because I'm secretly hoping it will force Signal to revisit the whole Signal PIN debacle and they will ultimately find a better solution.

codethief··on A cryptography engineer's perspective on quantum computing timelines
I never said I was considering any.[0] I'm strictly interested in what Signal is doing to keep (or even improve) its security guarantees.

On that note, Signal wouldn't even depend on Intel SGX for security nearly as much if Signal PINs weren't user-chosen but instead auto-generated with enough entropy. Yes, contact discovery through phone numbers would still be challenging, but secure value recovery[1] just requires a key with enough entropy.

[0]: For the record, Threema doesn't store your contact list server-side, unless you explicitly opt in. Similarly, now that Signal supports usernames, my understanding is that one could use the app without uploading one's contact list in plaintext.

> I'm not sure who particularly cares about the stuff Signal is doing with SGX anyway.

Security researchers like Matthew Green seem to care[0], the Signal people surely do, I myself do, too. Isn't that enough to raise that question?

> if you're paranoid enough to worry about it

You make it seem like that's an outlandish thought, when in reality there have been tons of reported vulnerabilities for SGX. And now QC represents another risk.

> it's not like Signal would be less secure than any other third party if SGX were broken

That's a weird benchmark. Shouldn't Signal rather be measured by whether it lives up to the security promises it makes? Signal's whole value proposition is that it's more secure than "third parties".

If by "mainstream E2E messenger" you mean WhatsApp and Facebook Messenger, sure. But I didn't realize those were the benchmark these days.
