Fun #ornithology fact for the weekend. Chickadees increase the number "dee" syllables in their calls as the potential threat of a predator increases. Small predators are considered more dangerous than big ones.

Beware of the book festivals!
(My latest @GuardianBooks cartoon)
ALT We see a stick figure running through a ravaged desert pursued by a mechanical claw.
The text begins "2050ad: Society has collapsed and the book festivals have gone rogue. Their terrifying motorized venues patrol the wastelands, hunting for audience members"
We can now see that the claw is on the front of an enormous, mad-max-style battle-rig, adorned with spikes, skulls and armour.
The text continues "Programmer-Warlords brutally preside over a relentless series of interviews, discussions and poetry readings.â
In the trailer of the truck, a poetry reading is taking place, in a tower above it, the huge, muscular, horned programmer raises his fists and yells orders to his minions. The monstrous vehicle thunders on leaving one lone stick figure behind
The text concludes "Occasionally, dazed survivors are found wandering with a signed hardback book in a cotton tote bag."

Many-shot jailbreaking exploits the long context windows of current LLMs. The attacker inputs a prompt beginning with hundreds of faux dialogues where a supposed AI complies with harmful requests. This overrides the LLM's safety training:

Amazon Fresh failure.
My third law of robotics, shared here yesterday is:
3. Technologies for robots need 10 years of steady improvement beyond lab demos of the target tasks to mature to low cost and to have their limitations characterized well enough that they can deliver 99.9% of the time. Every 10 more years gets another 9 in reliability.
Looks to me like Amazon did not remotely follow this when they introduced Just Walk Out to their Amazon Fresh stores in 2016. Touted as cameras seeing what you put in your cart there was no need to check out. Service cancelled this week. Turns out there were 1,000 remote cashiers in India: "It often took hours for customers to receive receipts after leaving the store, largely because offshore cashiers were rewatching videos and assigning items to different customers."
This story reports that in 2022 only 300 out of 1,000 walk outs did not need a human review, so 30% reliability against an Amazon target of 95%. Their business model built in a 5% failure rate, and even that was not even close to attainable.
Not the magic of AI that consumers believed they were partaking in. Hubris gets you every time in robotics (and AI...). gizmodo.com/amazon-reportedlâŚ

The following topics need *additional skilled C developers* to progress in a timely manner or at all (loosely ordered by descending priority):
- fixing a complex non-public security issue,
- teaming up on researching and fixing future security reports and ClusterFuzz findings with few-days-max response times in communication in order to (1) have a sound fix ready before the end of a 90 days grace period and (2) in a sustainable manner,
- implementing and auto-testing XML 1.0r5 support (needs discussion before pull requests),
- smart ideas on fixing the Autotools CMake files generation issue without breaking CI (needs discussion before pull requests),
Good news today: We've reestablished contact with the #MarsHelicopter after instructing @NASAPersevere to perform long-duration listening sessions for Ingenuityâs signal.
The team is reviewing the new data to better understand the unexpected comms dropout during Flight 72.
The #MarsHelicopter executed Flight 72 on Jan. 18, but on its descent, communication between Ingenuity and @NASAPersevere terminated prior to touchdown. The team is analyzing available data and considering next steps to reestablish comms. go.nasa.gov/4b3wRN6
When your garage is like mine, you accidentally pull out a box that contains.. a prototype of the worldâs first smartphone, the IBM Simon. Still works!
It will soon on its way to a good home
