#otd 2 years ago, I created the @passagemath.org fork of #SageMath, the comprehensive #OpenSource #Mathematics system in #Python. Almost 3000 Issues/PRs and 244 Releases later, we are at passagemath-10.8.13, fully modularized as envisioned in 2020, with support for Linux/macOS/Windows/WebAssembly. 🎉

I stopped using these terms in my classes b/c students tend to consult a wild mix of online resources anyway. I only use the more specific terms "standard equation form" and "standard inequality form". Both are max, >= 0. Standard equation form includes the full row rank condition for the matrix.

Chad Topaz Queer DEI Race Traitor @chadtopaz.bsky.social · 01/09/2026

That time your "philanthropic" foundation quietly scrubbed "racial justice" from its website? Yeah, I tabulated that. Foundations weren't even direct targets of Trump's anti-DEI orders — yet many cut DEI language anyway. The Wayback Machine remembers. Updated preprint: doi.org/10.31235/osf...

The Retreat from Diversity, Equity, and Inclusion: Language Change on Large U.S. Foundation Websites, 2019–2025

Chad M. Topaz,
Benham Cobb,
Frances Lu,
Aniya Smith,
Nathan Zekarias

Following the murder of George Floyd in 2020, many US organizations, including large private foundations, publicly foregrounded language related to DEI. Beginning in 2023, a series of legal and political developments shifted the institutional environment: the Supreme Court’s ruling in Students for Fair Admissions v. Harvard (2023), state-level anti-DEI legislation, and Executive Order 14151 (2025). Using the Internet Archive’s Wayback Machine, we construct a longitudinal corpus of archived web pages from thirteen large U.S. private foundations with established DEI vocabulary and track the frequency of sixty-seven DEI-related terms from 2019 to 2025. Among eight foundations with paired 2023 and 2025 data, six reduced their DEI word intensity; most terms present in the paired corpus declined, with race-related terms contributing the largest share of the drop. The aggregate decline on the full sixty-seven-term index is marginal (exact Wilcoxon p = .074, one-sided); evidence is stronger on the dictionary’s definitional core, the diversity-equity-inclusion triad and its variants (p = .031). The decline concentrates in the 2024–2025 window containing the January 2025 executive orders: eight of nine foundations fell (p = .020), with scattered movement earlier. Qualitative comparison of archived pages illustrates three pathways of retreat: elimination of equity framing, substitution of technical for justice-oriented vocabulary, and reduced prominence through site redesign. These patterns suggest institutional isomorphism operating in reverse—convergent abandonment amid shared political pressure—though our descriptive design cannot identify the mechanism. The findings establish an empirical baseline for tracking organizational communication about equity under political pressure.
