Researchers Show Copilot and Grok Can Be Abused as Malware C2 Proxies
Cybersecurity researchers have disclosed that artificial intelligence (AI) assistants that support web browsing or URL fetching capabilities can be turned into stealthy command-and-control (C2) relays, a technique that could allow attackers to blend into legitimate enterprise communications and evade detection.

No one expects you to. Listen & reply when you have time.

So you expect the recipients to read your text messages immediately, even if they're out, doing sports or meeting someone? Same stupid logic.

The God in the Wire: The Book That Began with an Empty Shelf
I did not set out to write a book about technology. I set out to understand an empty shelf. The shelf is at LaGuardia Community College in Long Island City, Queens, mounted on a corridor wall beneath a sign bearing the universal symbol for Deaf access. The shelf once held a TTY, one of those text telephones that gave Deaf people their first access to instantaneous distance communication.

This is a really good question from @…. The first thing I keep telling everyone in other cities who wonders how they can help, what they can do:
Get organized NOW. Meet your neighbors NOW. Get your neighbors set up with secure messaging NOW. Form multiple hyper-local neighborhood social groups NOW. Organize a block picnic or community craft night or repair workshop or whatever NOW. Get contact info for the human beings who physically show up for neighborhood events NOW.
Form all those local connections ASAP, so that they’re there when you need them. The hardest lines of communication to establish will be the ones with the people closest to you. If you get local lines open in advance, you’ll be in a far, far better place.

The Communication Complexity of Combinatorial Auctions with Additional Succinct Bidders
Frederick V. Qiu, S. Matthew Weinberg, Qianfan Zhang
https://arxiv.org/abs/2512.06585 https://arxiv.org/pdf/2512.06585 https://arxiv.org/html/2512.06585
arXiv:2512.06585v1 Announce Type: new
Abstract: We study the communication complexity of welfare maximization in combinatorial auctions with bidders from either a standard valuation class (which require exponential communication to explicitly state, such as subadditive or XOS), or arbitrary succinct valuations (which can be fully described in polynomial communication, such as single-minded). Although succinct valuations can be efficiently communicated, we show that additional succinct bidders have a nontrivial impact on communication complexity of classical combinatorial auctions. Specifically, let $n$ be the number of subadditive/XOS bidders. We show that for SA $\cup$ SC (the union of subadditive and succinct valuations): (1) There is a polynomial communication $3$-approximation algorithm; (2) As $n \to \infty$, there is a matching $3$-hardness of approximation, which (a) is larger than the optimal approximation ratio of $2$ for SA, and (b) holds even for SA $\cup$ SM (the union of subadditive and single-minded valuations); and (3) For all $n \geq 3$, there is a constant separation between the optimal approximation ratios for SA $\cup$ SM and SA (and therefore between SA $\cup$ SC and SA as well). Similarly, we show that for XOS $\cup$ SC: (1) There is a polynomial communication $2$-approximation algorithm; (2) As $n \to \infty$, there is a matching $2$-hardness of approximation, which (a) is larger than the optimal approximation ratio of $e/(e-1)$ for XOS, and (b) holds even for XOS $\cup$ SM; and (3) For all $n \geq 2$, there is a constant separation between the optimal approximation ratios for XOS $\cup$ SM and XOS (and therefore between XOS $\cup$ SC and XOS as well).

'minicom' is a TUI serial comms program - ideal for when you're dealing with real serial devices and you need to play with baud rates, and the like. It's not fancy, and frankly hasn't changed much in ages - but it comes in handy. In the last year I've used it with an Apple ][c, JavaStation, and Epson-HX20 - but even more modern stuff sometimes has that emergency rescue serial shell.

Classic thing we often ask him to stop doing is screaming (he screams a pretty normal amount for his age, but we're working on more productive forms of needs communication).
As we're reminding him of the challenge rules (stop when asked = 1 point), kid gets a twinkle in his eye and then screams briefly and looks at us.
Instant new rule: you don't get points for stopping activities that you started just to get points.
