Trump's $800M World Liberty Financial Token Stake Locked Until 2028

Onchain blockchain records have revealed that a crypto stake worth approximately $800 million, linked to Donald Trump's holdings in World Liberty Financial, has been moved into a vesting contract. The transfer effectively restricts any sale of the tokens for the foreseeable future. Under the terms of the contract, the stake cannot be sold until 2028. Additionally, a mandatory 10% token burn must occur before the holdings become transferable or sellable.

How Mixture of Experts Architecture Evolved from 1991 Research to DeepSeek-V3

Mixture of Experts (MoE) is an AI architecture that activates only a small subset of a model's parameters for each token, dramatically reducing compute costs compared to traditional dense models. The concept dates back to a 1991 paper by Jacobs, Jordan, Nowlan, and Hinton, which introduced a gating network to route inputs across multiple smaller expert networks, though all experts still ran on every input, offering no compute savings. The critical breakthrough came in 2017 when Google Brain researchers introduced sparse gating in their paper on Sparsely-Gated Mixture-of-Experts, where only the top-scoring experts are selected and executed per token. This sparse routing mechanism forms the foundation of modern large language model MoE designs. DeepSeek-V3 exemplifies the approach at scale, carrying 671 billion total parameters while activating only around 37 billion per forward pass.

Cleveland Plans 200 New Homes to Revive Near-East Side After Decades of Decline

Cleveland's near-East Side has seen a dramatic population drop, shrinking from nearly 100,000 residents in the 1960s to fewer than 20,000 today. To address this decline, the city has launched its Housing Innovation District initiative, targeting the construction of 200 new homes in the area. The project is backed by $2 million in state funding to help kickstart development. Additionally, a tax increment financing plan has been proposed, which could raise up to $182 million over 30 years. Those funds would be directed toward infrastructure improvements including streets, sewers, and parks.

Oracle HCM Position Hierarchies: Structure, Setup, and HDL Loading Explained

Oracle HCM's Position Hierarchy feature defines reporting relationships between organizational roles rather than individual employees, keeping the structure stable even when staff leave or move. Unlike manager-based hierarchies, which shift as people change roles, position hierarchies remain intact regardless of who occupies each slot. Organizations use them for workforce planning, vacancy management, approval routing, and headcount tracking. Setting up the feature requires enabling Position Management in Oracle HCM and creating positions with defined parent-child relationships. For large-scale implementations, HCM Data Loader (HDL) is commonly used to bulk-load positions and their hierarchical relationships in sequence.

What Five Background Removal APIs Actually Do With Your Users' Media

A technical review of five background removal APIs — Banuba Face AR SDK, Remove.bg, Photoroom, VideoBGRemover, and Veed on fal.ai — examined their data handling policies as documented on vendor pages on 8 September 2026. Four of the five are hosted services, meaning user media leaves the device and crosses a network before processing occurs; only Banuba's Face AR SDK processes footage on-device. Data retention practices vary significantly: VideoBGRemover publishes the most detailed erasure timeline, while Remove.bg and Photoroom leave key durations unstated. A notable security concern with fal.ai is that CDN-hosted files are publicly accessible to anyone with the link unless an access control list is explicitly applied. The review relied solely on vendors' own published documentation and did not involve independent testing, with the author cautioning that any figures used for build decisions should be obtained in writing directly from the vendor.

PolicyAware Framework Aims to Cut Latency in Enterprise AI Agent Safety Controls

As enterprise AI systems evolve from simple retrieval-augmented generation to autonomous agents that call tools and modify external state, traditional text-filtering safety measures are no longer sufficient. PolicyAware, an open-source Python framework, introduces a control-plane approach that enforces deny-by-default policies, PII and secret handling, tool governance, model routing, and audit logging before any side effects occur. The framework version 0.4.4, built on Python 3.10+, keeps its core dependencies lightweight to maintain a local, deterministic enforcement path with minimal overhead. Unlike conventional guardrails that focus solely on prompt and output inspection, PolicyAware evaluates identity, tenant, region, risk tier, and action context to make nuanced decisions including conditional allows and human-approval gates. Developers are advised to benchmark median, p95, and p99 latency in their own environments rather than relying on generalized performance claims.

Developer Tests RAG System Robustness by Swapping Every Embedder, Generator, and Judge Model

A software developer ran a structured experiment to determine whether a retrieval-augmented generation (RAG) pipeline's performance holds up when every model component is replaced. The frozen pipeline used simple 200-word chunks, cosine similarity retrieval, and a shared prompt, while three embedders, five generators, and three AI judges were swapped as variables. The evaluation set was expanded from 10 to 100 questions spanning four distinct topics, including 20 'refusal traps' where correct answers are absent from the corpus to test whether models answer from documents or pretrained memory. Three separate AI judges — from Claude, GPT, and Gemini — scored all answers independently to detect whether any judge favored outputs from its own model family. The goal was not to identify a winning model but to verify that the system's conclusions remain valid regardless of which vendor's models are plugged in.

AI Leaders Call for Slowdown, Citing Safety Amid Industry Scrutiny

Prominent figures in the artificial intelligence industry are now advocating for a more cautious pace of AI development, marking a shift from years of rapid, largely unchecked progress. Safety has emerged as the central justification for this proposed slowdown. However, analysts suggest that calls for restraint may also serve strategic business interests for established AI companies. A more regulated or slowed environment could benefit incumbents by raising barriers for newer competitors.

Why Simple Battery Backup Math Fails and How to Model It Accurately

Standard battery runtime calculations rely on linear division, but real-world electrochemical and power electronics behavior causes those estimates to overstate actual backup time by 30% to 50%. Three key factors drive this gap: Peukert's Law, which describes how higher discharge currents reduce usable battery capacity non-linearly; inverter tare losses, where idle power draw of 15W to 55W persists regardless of connected load; and depth-of-discharge limits, beyond which lead-acid and lithium batteries suffer irreversible degradation. A DEV Community article translates these physical principles into a deterministic TypeScript calculation engine using strictly typed, immutable inputs. The engine models effective capacity using Peukert exponents specific to battery chemistry, ranging from 1.03 for LiFePO4 to 1.30 for flooded lead-acid cells. The approach is particularly relevant for low-load scenarios, such as overnight CPAP or router use, where inverter tare losses can account for more than half of total battery drain.

Dev fixes memory-killing build step by replacing redundant rebuilds with record lookups

A software developer noticed their project's acceptance-check step was repeatedly killed by the OS out-of-memory killer four times over two days. Investigation revealed the step, named a 'read', was actually triggering a full recompile of all 15 project units just to extract pass/fail booleans — duplicating work already done by prior control runs. Each control run had already stored its result alongside the exact commit hash it ran against, making re-execution unnecessary. The fix replaced the costly rebuilds with a simple comparison of stored commit identifiers, adding a 'stale' counter to flag outdated records instead. The developer concluded that any observational step consuming resources disproportionate to mere data-gathering is likely re-deriving facts that already exist.

Solo founder builds OSPulse to catch supply-chain threats before CVEs are assigned

Rob, founder of small indie firm Fortitude Omnis Group Ltd, has introduced OSPulse, a software supply-chain security tool designed to detect risks before official vulnerability identifiers exist. Unlike mainstream tools from VC-backed competitors such as Snyk and Sonatype, OSPulse monitors maintainer churn, ownership changes, and commit-velocity drops across more than ten data feeds. A standout feature called PoisonBox runs every npm package install inside an isolated disposable microVM, using an eBPF kernel probe to record all processes, file access, and outbound connections without touching the host machine. Rob also disclosed a pricing bug in which the checkout displayed £249 per month while Stripe was configured to charge £2,988 as a lump sum, a discrepancy caught before any customer was billed and since resolved by tying all pricing to a single source of truth. The introduction was posted on developer community platform DEV as part of a self-introduction thread.

Kolkata May Rename Roads Honoring Marx, Lenin and Ho Chi Minh

Three major roads in Kolkata — Lenin Sarani, Karl Marx Sarani, and Ho Chi Minh Sarani — are under consideration for renaming. The proposal has drawn attention given the historical significance of these names, which reflect the city's long association with left-wing politics. The renaming discussion comes amid broader debates across India about revisiting place names with ideological or colonial origins. No official decision has been announced yet regarding what the roads would be renamed to.

How Data Modeling, Schemas, and Joins Shape Power BI Report Performance

A practical guide published on DEV Community explains core data modeling concepts in Microsoft Power BI, a business intelligence tool used to connect data sources and build reports and dashboards. The article compares three structural approaches — flat table, star schema, and snowflake schema — outlining the roles of fact and dimension tables in each design. It highlights why a well-structured data model matters, noting that poor design leads to slow performance, inflated file sizes, and inaccurate report figures. The guide also covers how relationships and filter direction operate within the data model, and how Power Query joins differ from model-level relationships. A recommended approach for structuring a typical BI solution is included, with star schema presented as a scalable and report-friendly option despite its data redundancy trade-offs.
