This piece from @… does a magnificent job of explaining this. The longstanding US strength in technology and innovation is coming to a rapid and catastrophic end right before our eyes. It’s self-inflected, it’s immoral, it’s horrifying, it’s stupid, and it’s utterly preventable.

Thoughts on Rust hashing
In languages like Python, Java, or C++, values are hashed by calling a “hash me” method on them, implemented by the type author. This fixed-hash size is then immediately used by the hash table or what have you. This design suffers from some obvious problems, like: How do you hash an integer? If you use a no-op hasher (booo), DoS attacks on hash tables are inevitable. If you hash it thoroughly, consumers that only cache hashes to optimize equality checks lose out of performance.

Every company is undergoing an invisible reorg. You report to your boss but your boss reports to an #AI, offloading the job of management entirely onto a bot and then merely communicating its wishes back to the team.
This is the Nothing Manager, surrounded by #LLM tools to avoid having to interact with…

AI is not an assistant – it's your new boss (The Everything App part 2)
As managers continue to outsource data-gathering and decision-making to LLMs, the person above you on the org chart is transforming into a chatbot's clerk – and leaving product teams with the consequences.

Yesterday managed to see at least a half dozen bands for #Kenmore Porchfest (#Buffalo). I only remembered to take one pic (at this RAtM cover band, Anger Is a Gift). They did a great job and the hosts had a cooler of water for everyone.
Kudos to everyone involved in the day.

On the sum of the largest and smallest eigenvalues of odd-cycle free graphs

On the sum of the largest and smallest eigenvalues of odd-cycle free graphs
Let $G$ be a graph with adjacency eigenvalues $λ_1 \geq \cdots \geq λ_n$. Both $λ_1 + λ_n$ and the odd girth of $G$ can be seen as measures of the bipartiteness of $G$. Csikvári proved in 2022 that for odd girth 5 graphs (triangle-free) it holds that $(λ_1+λ_n)/n \le (3-2\sqrt 2) < 0.1716$. In this paper we extend Csikvári's result to general odd girth $k$ proving that $(λ_1+λ_n)/n = O(k^{-1})$. In the case of odd girth 7, we prove a stronger upper bound of $(λ_1+λ_n)/n < 0.0396$.

Agreed, great series about the enshittification

On the error term of the fourth moment of the Riemann zeta-function

On the error term of the fourth moment of the Riemann zeta-function
We examine the size of $E_{2}(T)$, the error term in the asymptotic formula for $\int_{0}^{T} |ζ(1/2 + it)|^{4}\, dt$ where $ζ(s)$ is the Riemann zeta-function. We make improvements in the powers of $\log T$ in the known bounds for $E_{2}(T)$ and $\int_{0}^{T} E_{2}(t)^{2}\, dt$. As a consequence, we obtain small logarithmic improvements for $k$th moments where $8\leq k\leq 12$. In particular, we make a modest improvement on the 12th power moment for $ζ(s)$.
