US Law Enforcement Warns of ‘Anti-Tech Extremism’ as AI Hatred Grows
As Americans stew over the looming risk of job-stealing AI and data centers in their back yards, the feds are raising the alarm about a new category of threat, documents obtained by WIRED show.

The Pentagon updated its official war casualty database over the weekend, adding more than 140 wounded service members.
The Defense Casualty Analysis System (DCAS) also introduced a new casualty category labeled “Overseas Operations” for personnel killed and wounded “starting July 7”.
According to the updated database, the official toll for the earlier phase of the US-Iran war, known as Operation Epic Fury,
now stands at 14 service members killed and more than 400 wounded …

Security Vulnerability Patterns in AI-Generated Code: A Cross-Model Comparative Study

https://arxiv.org/abs/2607.20713 https://arxiv.org/pdf/2607.20713 https://arxiv.org/html/2607.20713
arXiv:2607.20713v1 Announce Type: new
Abstract: LLM-based coding tools enable non-expert users to generate routine automation scripts that may enter enterprise workflows without meaningful security review. This study examines that risk directly. Code was collected from ChatGPT, Microsoft Copilot, and Google Gemini using identical prompts across three automation domains. Claude Code performed a standardized vulnerability review. Each identified vulnerability was scored using CVSS v3.1 and mapped to the OWASP Top 10:2021 and the MITRE ATT&CK frameworks. Every script contained exploitable vulnerabilities. Nine of the 17 identified vulnerability classes appeared in code from all three models, while 14 of the 17 vulnerability classes appeared in at least two models. The weighted CVSS scores across platforms differed by less than 10%. The risk is not tied to any particular model but rather to the task category. Organizations should therefore ask not which tool to trust, but instead whether LLM-generated automation code should be deployed without review.

Designed-Source Reductions and a Dual-Purpose Feasibility Band for Semantic Rate-Distortion
Joss Armstrong
https://arxiv.org/abs/2606.11280 https://arxiv.org/pdf/2606.11280 https://arxiv.org/html/2606.11280
arXiv:2606.11280v1 Announce Type: new
Abstract: The joint rate-distortion framework of Stavrou and Kountouris (IEEE Transactions on Communications 2023) characterises dual-fidelity tradeoffs for semantic communication on stochastic semantic sources. Many task-oriented communication systems instead use designed sources, where the semantic object is a deterministic oracle allocation $\phi^(t)$ rather than a stochastic quantity given by nature. We isolate the subclass of designed sources under smooth concave utility with assumptions A1, A2 and Euclidean allocation codomain, and restrict the encoder class to deterministic common-category mappings. Within this subclass the SK exponential-tilting decoder and generalised Blahut--Arimoto iteration specialise to conditional-mean decoding and Lloyd--Max stationarity on $\phi^(t)$. When the second fidelity is a monotone single-letter distortion, the joint problem stays inside the SK admissible class; the common-category SK rate is lower-bounded by the max of the corresponding Shannon rate-distortion functions, with equality only when the common-category reconstruction is compatible and RDF-optimal. When the second fidelity is aggregate verification, the joint problem leaves the SK single-letter class and admits a constrained-design feasibility band $R_{\min}(\varepsilon^) \leq R \leq R_{\max}(\beta^)$ of width $\log_2(K_{\max}/K_{\min})$ bits in partition cardinality. The reduction and the band are scope statements on the SK apparatus, not modifications to it. A smart-grid economic-dispatch example with a non-technical-loss-detection contrast illustrates the band.

Universal Assembly and Cellular Loop Spaces on Regular CW Complexes
Serhii Dylda, Tibor Macko
https://arxiv.org/abs/2606.05051 https://arxiv.org/pdf/2606.05051 https://arxiv.org/html/2606.05051
arXiv:2606.05051v1 Announce Type: new
Abstract: We develop a regular CW analogue of the classical assembly formalism for chain complexes appearing in algebraic surgery theory. From the cell poset, we construct combinatorial path and loop objects using fences of comparable cells and prove that their classifying spaces recover the homotopy types of the ordinary based path and loop spaces. The resulting loop object carries a natural monoid structure, giving rise to a DG algebra defined directly from the cellular structure.
For complexes of cellular cosheaves, we introduce a universal assembly functor to modules over the group ring of the fundamental group and study the localization determined by global equivalences. The associated homotopy category is identified with a Verdier quotient of the derived category of cellular cosheaves, and its fibrant objects are precisely the homotopy locally constant complexes. A single elementary cosheaf becomes a compact generator after localization, and its derived endomorphism DG algebra is identified with singular chains on the cellular loop space. Consequently, the localized theory admits a Morita description in terms of DG modules over the loop DG algebra. The formalism provides a regular CW counterpart of the classical delta-set approach to assembly in algebraic surgery theory due to Ranicki and Weiss.

Very interesting developments in Ukraine. I can only think it is normal for a state that is at war to have very strong opinions within its government.
“One participant in the president’s meeting with lawmakers recounted Zelensky’s words this way:
They live in two different worlds. [DM] Misha wants to digitize everything, to build a system around technology. The military just wants to be heard. They ask for one category of weapons to be procured, and he refuses and funds other areas instead. They’ve simply stopped hearing each other. I can’t allow the Defense Ministry and the General Staff to be at war with each other in a country that’s at war. Ideally, I’d replace them both. But I can’t do that at the same time.”
I just hope they can keep and achieve the goal to push Russia out of Ukraine.

Abstract: We reinvestigate the theory of spectral sequences by studying the $(\infty,1)$-category of filtered spectra through the cofiber-of-$\tau$ formalism of Burklund-Isaksen-Pstragowski-Wang-Xu. In this framework, we define and analyze hidden extensions along arbitrary maps of filtered spectra, establishing computational principles that extend the generalized Leibniz rule and the generalized Mahowald trick of Lin-Wang-Xu, as well as Burklund's Leibniz rule for total differentials, from the Adams spectral sequence to this broader setup. Our formulation uses a more refined, layered notion of extension, which slightly sharpens these statements even for the Adams spectral sequence. As an application, we study equivariant slice spectral sequences and obtain new families of "exotic transfer" differentials in the $C_4$-slice spectral sequences for the Hill-Hopkins-Ravenel theories $\mathrm{BP}^{((C_4))}\langle m\rangle$ for every $m \ge 1$.

This is the bispan analogue of the Burnside ring of $G$. The ring $P(G)$ admits a third operation from composition of bispans. We produce a character map for $P(G)$ landing in a plethory built out of polynomial rings and the poset of conjugacy classes of subgroups of $G$. We prove that the character map sends composition of bispans to the plethysm operation -- which is a generalization of composition of polynomials.

In an earlier post I introduced the principle that there were four categories of side hustle. Let’s now talk about the second category.
𝗦 𝗤𝘂𝗮𝗱𝗿𝗮𝗻𝘁: 𝗢𝘄𝗻𝗶𝗻𝗴 𝘁𝗵𝗲 𝗝𝗼𝗯 (𝗮𝗻𝗱 𝘁𝗵𝗲 𝗦𝘁𝗿𝗲𝘀𝘀)
Self-employed side hustles mean 𝒚𝒐𝒖 are the business.
Examples:
• Coaching
• Consulting
• Service-based businesses
𝐏𝐫𝐨𝐬:
✔ More control
✔ Higher income potential
✔ Uses your experience
𝐂𝐨𝐧𝐬:
✖ Still time-dependent
✖ Hard to step away
✖ Burnout risk
💡 Many people leave a job… only to create a more demanding one.

In an earlier post I introduced the principle that there were four categories of side hustle. Let’s talk about the first category.
Employee-style side hustles pay you for hours worked.
Examples:
• Gig work
• Freelancing by the hour
• Part-time jobs
𝐏𝐫𝐨𝐬:
✔ Easy to start
✔ Immediate income
✔ Low learning curve
𝐂𝐨𝐧𝐬:
✖ No leverage
✖ No scalability
✖ Income stops when time stops
💡 These hustles can help short-term – but they rarely change your financial future.
𝐇𝐨𝐧𝐞𝐬𝐭 𝐪𝐮𝐞𝐬𝐭𝐢𝐨𝐧:
Are you building income… or just filling time?

In an earlier post I introduced the principle that there were four categories of side hustle. Let’s now talk about the fourth and final category.
𝗜 𝗤𝘂𝗮𝗱𝗿𝗮𝗻𝘁: 𝗪𝗵𝗲𝗻 𝗠𝗼𝗻𝗲𝘆 𝗗𝗼𝗲𝘀 𝘁𝗵𝗲 𝗪𝗼𝗿𝗸
Investor income is built on capital, not hours.
Examples:
• Stocks
• Real estate
• Digital assets
𝐏𝐫𝐨𝐬:
✔ Potentially passive
✔ Long-term wealth
✔ True financial independence
𝐂𝐨𝐧𝐬:
✖ Requires capital
✖ Risk if poorly educated
✖ Results take time
💡 Most investors don’t start here.
They fund this quadrant using income from other quadrants!

Which quadrant is financing your future?

In an earlier post I introduced the principle that there were four categories of side hustle. Let’s now talk about the third category.
𝗕 𝗤𝘂𝗮𝗱𝗿𝗮𝗻𝘁: 𝗕𝘂𝗶𝗹𝗱𝗶𝗻𝗴 𝗦𝘆𝘀𝘁𝗲𝗺𝘀, 𝗡𝗼𝘁 𝗝𝘂𝘀𝘁 𝗜𝗻𝗰𝗼𝗺𝗲
Business-owner side hustles focus on leverage.
Examples:
• Online businesses
• Automated systems
• Team-based models
𝐏𝐫𝐨𝐬:
✔ Scalable
✔ Time flexibility over time
✔ Can become a true asset
𝐂𝐨𝐧𝐬:
✖ Learning curve
✖ Requires patience
✖ Needs structure and mentorship
💡 This is where side hustles stop being “extra money” and start becoming 𝐨𝐩𝐭𝐢𝐨𝐧𝐬. To me, 𝐭𝐡𝐢𝐬 𝐢𝐬 𝐭𝐡𝐞 𝐛𝐞𝐬𝐭 𝐭𝐲𝐩𝐞 𝐨𝐟 𝐬𝐢𝐝𝐞 𝐡𝐮𝐬𝐭𝐥𝐞 𝐭𝐨 𝐭𝐚𝐫𝐠𝐞𝐭. Remember, the whole point of a side hustle is that you can start one while already doing something else.
