The auDA, and some 3rd-party identify service and my Registrar are a joke!

WOW! I just had to share this little story I ran into today.

I tried to register a .AU Domain the other day, only for it to instantly fail.

I emailed support, which took several days to respond, only for them to respond by saying (paraphased):

We’re sorry, but the identify checks failed. The 3rd-aprty service doesn’t tell us why, But, please make sure that the ID you used matches the Full Name, including any Middle name(s).

I used my Passport number. Which of course has my First, Middle and Last Name.

I can only assume at this point that the checks failed on the missing “Middle name”. Why? Because the Registrar I use has a database and user interface for “contacts” that only have support for First name and Last name. NO Middle Name.

🤦‍♂️ This is basically stupid at this point. Systems cannot be trusted at the most fundamental level, no matter how good they are.

Until we figure out how to build a system that allows an individual to prove to another entity that they are who they say they are without a shred of doubt (i.e: cryptographically), we’re stuffed.

There is literally nothing I can do in this case. The auDA are at fault. The 3rd-party identify service (unknown) are at fault. The registrar are at fault. Hell, even the Passport office are at fault for even bothering to or requiring a Middle name.

How has “identity” come to this?

As an enjoyer of delightfully bad graphic design, found on most Czech village center cork boards, I’m sad to see the stolen clipart and badly cropped watermarked stock images, gradually replaced with AI slop.

This is far from a serious rant, but generating images of my kind being telepathically hit with sharp rocks, surely gives me a right to complain.

So far these seem the most prominent slop categories, seem to be…

Architecture slop:

  1. find a sketch of what an old building looked like

  2. generate an AI version, without correcting any of the perspective errors - this one is diagonally levitating

  3. generate a recreation of the buildings demise - after going through the AI, for the second time, it is now a completely different building

Moralizing slop:

History slop:

@klaxzy@klaxzy.net I should cancel Netflix as well. Back when they started their streaming service, it was a revelation: Finally, I could watch interesting shows in English, without having to wait for years, and legally (I like to be a paying customer, if it’s good). But this is long over. The interesting shows are gone or, once again, I have to wait for years until they’re available on Netflix. So, why bother anymore? 🤷‍♀️

↳ In-reply-to » Another AI rant:

@movq@www.uninformativ.de that’s the way large language models work, with a prompt. Rather than entering the prompt, most inference providers allow for specific files to be created that define the scope of what’s been requested, the skills the model is supposedly to posses, the stuff to “remember”, etc. Some will “learn” and add that “knowledge” to the proper files.

Another AI rant:

One of the “key features” of LLMs is that you can use “natural language”, because that is supposed to be easier than having to learn a programming language. So, when someone says to me, “I automated this process using AI!”, what they mean is: They have written a very, very large Markdown document. In this document, they list what the AI is supposed to do.

In prose.

This is a complete disaster.

Programming and programming languages have one crucial property: They follow a well-defined structure and every word has a well-defined meaning. That is absolutely brilliant, because I can read this and I can follow the program in my head. I can build a mental model. I can debug this, down to the precise instructions that the CPU executes. This all follows well-defined patterns that you can reason about.

But with these Markdown files, I am completely lost. We lose all these important properties! No debugging, no reasoning about program flow, nothing. It’s all gone. It’s a magic black box now, literally randomized, that may or may not do what you wanted, in some order.

People now throw these Markdown files at me … and … am I supposed to read this? Why? It’s completely random and fuzzy.

Sadly, these AI tools are good enough to be able to mostly grasp the authors intentions. Hence people don’t see the harm they cause, because “it works”.

We already have a ton of automations like this at work: Tickets get piped through an LLM and these Markdown files / prompts determine what will happen with the ticket, and maybe they trigger additional actions as well, like account creation or granting permissions. All based on fuzzy natural language – that no two humans will ever properly agree on.

Jesus Christ, we’re now INTENTIONALLY bringing the ambiguity of legal texts and lawyers into programming.

Using natural language is NOT easier than using a programming language. It is HARDER. Have you people never read a legal contract? And that stuff can STILL be debated in a court room.

I can’t begin to comprehend why we, tech folks, push this so hard. What is wrong with you? Or me?

(And, once again, we’re ignoring other factors here. LLMs use a ton of energy and ressources, that we don’t have to spare. It’s expensive as fuck. It doesn’t even run locally on our servers, meaning we give all these credentials and permissions to some US company. It’s insane.)

It’s concerning, I’ve warned about it many times, nobody listens.

I think the best thing one can do is explicitly not use any AI tools but keep your actual skills intact. Might be out of a (good) job for a while, but once this bubble bursts, this is who is going to get hired again. (I think.)

And considering how insanely expensive all this is, I’m still (mostly) convinced that the bubble will actually burst. This stuff just isn’t sustainable.

… or I might be wrong. And if so, I see an even darker future that I don’t want to put into words right now.

@lyse@lyse.isobeef.org AI result ahead, feel free to ignore.

I “asked” the AI at work the same question out of morbid curiousity. It “said” that SQLite converts that integer to floating point internally on overflows and then, when converting back, the x86 instruction cvttsd2si will turn it into 0x8000000000000000, even if the actual floating point value is outside of that range. So, yes, it allegedly actually saturates, as a side effect of the type conversion.

I couldn’t find anything about that automatic conversion in SQLite’s manual, yet, but an experiment looks like it might be true:

sqlite> select typeof(1 << 63);
╭─────────────────╮
│ typeof(1 << 63) │
╞═════════════════╡
│ integer         │
╰─────────────────╯

sqlite> select typeof((1 << 63) - 1);
╭──────────────────────╮
│ typeof((1 << 63) ... │
╞══════════════════════╡
│ real                 │
╰──────────────────────╯

As for cvttsd2si, this source confirms the handling of 0x8000000000000000 on range errors: https://www.felixcloutier.com/x86/cvttsd2si

The following C program also confirms it (run through gdb to see cvttsd2si in action):

<a href="https://txt.sour.is/search?q=%23include">#include</a> <stdint.h>
<a href="https://txt.sour.is/search?q=%23include">#include</a> <stdio.h>

int
main()
{
    int64_t i;
    double d;

    /* -3000 instead of -1, because `double` can’t represent a
     * difference of -1 at this scale. */
    d = -9223372036854775808.0 - 3000;

    i = d;
    printf("%lf, 0x%lx, %ld\n", d, i, i);

    return 0;
}

(Remark about AI usage: Fine, I got an answer and maybe it’s even correct. But doing this completely ruined it for me. It would have been much more satisfying to figure this out myself. I actually suspected some floating point stuff going on here, but instead of verifying this myself I reached for the unethical tool and denied myself a little bit of fun at the weekend. Won’t do that again.)

@lyse@lyse.isobeef.org

Disclaimer: Can’t guarantee that I’m fully awake and I’m being trained at work not to use my brain anymore, so maybe this is complete bullshit. 😪🧟‍♀️

It says here that SQLite uses signed integers:

https://sqlite.org/datatype3.html

In pure bits, 1 << 63 would be 0x8000000000000000, but as a signed value, it gets interpreted as -9223372036854775808. Subtracting 1 yields -9223372036854775809 – but that doesn’t fit in 64 bits anymore. It’s possible that SQLite doesn’t want to wrap around but instead saturates? Haven’t checked. 🤔

With 62 bits, there is enough room.

With 1 << 64, I have no idea how SQLite wants to handle this, because this should immediately trigger a warning, because it doesn’t fit right away. Maybe it gets truncated to 0?

sqlite> select printf('0x%x', 2 * (1 << 64));

Everything changes, right? I know we sound like curmudgeons, and perhaps AI is the next step. We are living its early infancy, the struggles and dislikes, the errors and flaws, and generations after us will simply benefit from it, and see it as natural as my children see the Internet today (it isn’t natural to me, I was born way before it).

Or maybe AI isn’t the next step. Either way, whether we like it or not, there is truly absolutely nothing (or close to) we can do. Well, complain we can, of course. :-P

@lyse@lyse.isobeef.org Oops, I guess the new text is a bit obscure. If you follow the link, the text is a bit more explicit, but you still need to know what a lexical scope is. Anyway, this is part of Perl moving very carefully toward being UTF-8 by default while also not breaking code written in the 90s. If you name a recent version like “use v5.42;” then Perl stops letting you use non-ASCII characters unless you also say “use utf8;”. The “lexically” part basically means that strictness continues until the next “}”, or the end of the program. That lets you fix up old code one block at a time, if you aren’t ready to apply the new strictness to a whole file at once.
