GNU Linux-libre 7.0 Deals With Deblobbing More Drivers & Cleansing DT Files
Building off last night’s release of the Linux 7.0 kernel is now the GNU Linux-libre 7.0-gnu kernel release for that downstream kernel that removes support for loading non-free-software kernel modules, blocks the loading of loadable microcode/firmware even when it means greatly reduced hardware support, and other sanitization of code in the name of software freedom… ⌘ Read more

Linux 7.0 Released With New Hardware Support, Optimizations & Self-Healing XFS
As expected the stable Linux 7.0 kernel was just released today in marking this next kernel release. The Linux 7.0 milestone comes due to Linus Torvalds’ preference of bumping the major version number after hitting X.19 as opposed to any single major change, but in any event there are a lot of great improvements and changes to find with this new kernel version. Linux 7.0 is also what’s powering the upcoming Ubuntu 26.04 LTS release… ⌘ Read more

@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://we.loveprivacy.club/search?q=%23include">#include</a> <stdint.h>
<a href="https://we.loveprivacy.club/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));
