@jon Updated the notes for this Wednesday’s session with some definitions:
- Undefined Behavior (UB)
- Uninitialized variables
- MemorySanitizer (MSan)
and added more resources.
Thanks to practicalswift for his pedagogical efforts and work on this in Bitcoin Core.
Breaking encryption puts everyone at risk.
"Even the Defense Department is now pointing out that the government’s quest to weaken encryption lies somewhere between counterproductive and downright harmful." https://www.vice.com/en_us/article/akwwn5/the-defense-department-says-it-needs-the-encryption-the-fbi-wants-to-break
Notes and questions for next week's PR review club are up!
This is a good opportunity to learn about and discuss ways to mitigate uninitialized variables and improve our reviewing and testing.
Today’s Bitcoin Core PR review club is on #16702 "p2p: supplying and using asmap to improve IP bucketing in addrman".
If you've been wanting to learn about Erebus, Eclipse attacks, BGP hijacking and network-level attacks on Bitcoin, this week’s study notes and questions are a great place to start.
The session is today at 18:00 UTC on IRC #bitcoin-core-pr-reviews

@jon can't overstate how great it is to have a vendor that actually fixes BIOS issues that affect Linux
ASUS, after i went through all the trouble to make a bug report for the e820/ACPI table, just replies with "use a supported OS!" 😠 not that they even bother with BIOS updates after the first year or so !
@jon i've already upgraded my 15 v4 recently, the vbios change is great: my external 4k monitor works *as 4k* in wayland after
Time to update coreboot, it seems https://puri.sm/posts/coreboot-4-11-leaving-no-librem-behind/
Joinmarket 0.6.1 bugfix release out
(bug was basically deposits not showing, without a rescan, if there are a lot of them because of a failure of the address import mechanism)
Next Wednesday’s PR review club is on #16702 "p2p: supplying and using asmap to improve IP bucketing in addrman" to diversify connections and increase Bitcoin's network security. This PR proposes one countermeasure among several to the Erebus attack.
Come discuss Bitcoin network security and the Erebus, Eclipse, and BGP hijacking attacks.

If you don't have the time to check out the Stephan Livera podcast w/ @jon on contributing to Bitcoin Core give the transcript a read. Was a great interview https://diyhpl.us/wiki/transcripts/stephan-livera-podcast/2019-11-13-jon-atack/
New article in Bitcoin Magazine on @waxwing's SNICKER non-interactive mixing proposal:
Interesting thoughts here .. the scriptless script construct gives a lot of flexibility in how LN channels can work - like Jonas I remember being very struck by Conner's talk on this last year:
