There were ~16mn users of the internet in 1995. As of 2025 there are 5.56bn. Are you saying paedophilia has dropped by 99.7% over 30 years? If so, please provide a source for that claim.

New comment by ctz in "Neato vacuum robots to stop working"

ctz — Sat, 29 Nov 2025 08:35:35 +0000

I have a Neato D650 which I assume meets that classification and is covered by the service withdrawal, it is now pretty degraded -- no notifications, no mapping, no keep-out zones.

No notifications means if it gets stuck it stays there.

No mapping means if it doesn't fully clean the space (eg, a door is closed) then I have no way of knowing without baby-sitting it.

No keep-out zones means every clean involves carefully preparing the space to hang up trailing wires out of the way -- previously I just had some keep-outs near the wires and that worked perfectly.

Without all these features I have stopped using it; it is quicker to just use a stick vacuum.

I understand that part. Mostly interested where the runners are coming from? macOS especially is pretty costly to provide runners for, so who is doing that for free?

> You can have a nice CI/CD pipeline that runs 100% in-house, for free.

Interested! Some detail on how you achieve this for free would be great.

asn1 enjoyers can also look forward to the sweet release of death. though if you end up in hell you might end up staring at XER for the rest of eternity

The other base64 prefix to look out for is `MI`. `MI` is common to every ASN.1 DER encoded object (all public and private keys in standard encodings, all certificates, all CRLs) because overwhelmingly every object is a `SEQUENCE` (0x30 tag byte) followed by a length introducer (top nibble 0x8). `MII` is very very common, because it introduces a `SEQUENCE` with a two byte length.

FWIW there is a similar effort for Rust using cranelift: <https://github.com/rust-lang/rustc_codegen_cranelift>

ctz — Tue, 20 May 2025 22:06:50 +0000

It is instructive to compare Bun and Deno's issue tracker. Like, the five most recent issues for Bun at the time of writing are all crashes. Some of these are controlled panics or assertion failures, but others are like "we are now executing from address -1" or "we are trying to read from address 0x00000069." Recently written software simply should not have these classes of problem.

New comment by ctz in "Bringing Faster Exceptions to Rust"

ctz — Thu, 07 Nov 2024 14:13:24 +0000

The topic is how to make non-local returns faster. I would suggest that normal returns are massively faster, and not returning at all is faster still (zero instructions needed!) -- but neither of these are non-local returns.

New comment by ctz in "Rustls Outperforms OpenSSL and BoringSSL"

ctz — Tue, 22 Oct 2024 21:32:10 +0000

Note that the AVX-512 code we're referring to is the code that Intel also contributed to OpenSSL.

As a side-note, I believe the CPU we tested this on does not suffer from the AVX-512 power limits reported with earlier AVX-512 parts. https://travisdowns.github.io/blog/2020/08/19/icl-avx512-fre... seems to confirm that.

  Runtime errors surface when a program
  runs into an unexpected condition or situation
  such as dividing by zero, memory overflow, or
  addressing a wrong or unauthorized memory
  location or device, or when a program tries to
  perform an illegitimate or unauthorized operation
  or tries to access a library, for example.
  The programs must be thoroughly tested for
  various types of inputs (valid data sets, invalid
  data sets and boundary value data sets) and
  conditions to identify these errors. Once identified,
  runtime errors are easy to fix.

Embarrassing horseshit.
