Economist Justin Wolfers: “Demolishing the East Wing of the WH before finalizing plans for what will be built above its ruins is a near-perfect metaphor for Trump’s approach to economic policy.
The only difference is the wrecking crew doesn’t claim the rubble is evidence of unprecedented growth.”

… Ukraine’s peace negotiators met with the US delegation today, which was led by Sec of State Marco Rubio, special envoy Steve Witkoff, and Trump son-in-law Jared Kushner. After multiple recent revelations about Witkoff being owned by Putin, he looked pretty uncomfortable facing the Ukrainians he has worked so hard to sell out.

1987 war zumindest eine Zeit mit besonderen Designs. Hier der Titel einer schulpolitischen Broschüre der baden-württembergischen Grünen aus dieser Zeit.

Vor einem mit lila Tintenflecken übersäten grünen Hintergrund ist eine Comic-Hand zu sehen, die ein als Papierflieger gefaltetes Zeugnis wirft. Oben steht groß "Umbau des öffentlichen Schulwesens" (Helvetica, weiß auf schwarz, wenn ich das richtig identifiziere). Unten links ist ein Logo "Die Grünen" zu sehen, zum damaligen Zeitpunkt ein lila Quadrat mit Schattenwurf und Sonnenblume in schwarz-weiß.

by accident i stumbled on this review by the #NSA on Bruce Schneiers "Applied Crypto" book from long ago.

9. BOOK REVIEW: APPLIED CRYPTOGRAPHY [censored] Reviewer Applied Cryptography, for those who don't read the internet news, is a book written by Bruce Schneier last year. According to the jacket, Schneier is a data security expert with a master's degree in computer science. According to his followers, he is a hero who has finally brought together the loose threads of cryptography for the general public to understand. Schneier has gathered academic research, internet gossip, and everything he co…
Issue 1 TALES OF THE KRYPT Page 14 of 16 oc ID: 6823780 Playing loose with the facts is a serious problem with Schneier. For example in discussing a small-exponent attack on RSA, he says "an attack by Michael Wiener will recover e when e is up to one quarter the size of n." Actually, Wiener's attack recovers the secret exponent d when e has less than one quarter as many bits as n, which is a quite different statement. Or: "The quadratic sieve is the fastest known . algorithm for factoring numb…

Two workers are quadratically better than one
For latency, anyway. A common architecture pattern is the “task queue”: tasks enter an ordered queue, workers pop tasks and process them. This pattern is used everywhere from distributed systems to thread pools. It applies just as well to human systems, like waiting in line at a supermarket or a bank. Task queues are popular because they are simple, easy to understand, and scale well. There are two primary performance metrics for a task queue.

Kronecker second limit formula for real quadratic fields
In this paper, the second Kronecker ``limit" formula for a real quadratic field is established for the first time. More precisely, we obtain the second Kronecker limit formula of Zagier's zeta function. Using the reduction theory of Zagier, which connects Zagier's zeta function to the zeta function of real quadratic fields, we express the values of the zeta function of narrow ideal classes in real quadratic fields at natural arguments in terms of an analytic function which we call the \emph{hig…

arxiv.org/abs/2510.11990

Linear Convergence of a Unified Primal--Dual Algorithm for Convex--Concave Saddle Point Problems with Quadratic Growth
In this paper, we study saddle point (SP) problems, focusing on convex-concave optimization involving functions that satisfy either two-sided quadratic functional growth (QFG) or two-sided quadratic gradient growth (QGG)--novel conditions tailored specifically for SP problems as extensions of quadratic growth conditions in minimization. These conditions relax the traditional requirement of strong convexity-strong concavity, thereby encompassing a broader class of problems. We propose a generali…
