GnuPG 2.5.19 released
Werner Koch has announced
the release of GnuPG 2.5.19. This release includes a few new options
and a number of bug fixes, and comes with the reminder that the
GnuPG 2.4 series will reach end-of-life soon

The main features in the 2.5 series are improvements for 64 bit Windows
and the introduction of Kyber (aka ML-KEM or FIPS-203) as PQC encryption
algorithm. Other than PQC support the 2.6 series will not differ a lot
from 2.4 because th … ⌘ Read more

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));

[$] A flood of useful security reports
The idea of using large language models (LLMs) to discover security problems is
not new. Google’s Project Zero
investigated
the feasibility of using LLMs for security research in 2024. At the time, they
found that models could identify real problems, but required a good deal of
structure and hand-holding to do so on small benchmark problems. In February
2026, Anthropic
published a report
