RSS-Link-Database-2025 is a Django-based GitHub project that collects link metadata (title, description, publish date) into a year-based RSS archive. It stores data for 2020–2026 with daily entries, using sources.json and domains.json to document sources and domains. The repo enables data analysis on link rot, RSS publishing patterns, domain configuration, and vocabulary across topics. It emphasizes time-capsule captures rather than replacing Internet Archive or Google, and notes focus on credible sources. Licensed GPL-3.0.

Merging two hash maps can be slow despite linear complexity because sharing the same hasher creates primary clustering, saturating early buckets during merge. Tests across Abseil, Boost, unordered_dense, khashl, and hashbrown show some libraries are >20× slower for merges than creation. Three fixes: (I) salted hashes to randomize bucket placement; (II) preallocation to reserve space for both maps; (III) non-linear (stride) iteration to avoid clustering. Conclusion: preallocation is easiest and often fastest when duplicates are few; salted hasher improves robustness; stride iteration is balanced but harder to implement. No single winner; choose by use case.

Google has filed a lawsuit against SerpApi for unlawful scraping that circumvents security and copies copyrighted content that appears in Google search results. Google accuses SerpApi of cloaking, vast bot networks, and fake names to harvest content licensed from Google and others (including Knowledge Panel images and real‑time data) and resell it. Google says it honors website directives and crawls per standards, while SerpApi disregards rights and directives. The action follows similar lawsuits and is part of Google's broader effort to combat web abuse.

The Napoleon Technique advocates postponing action on non-urgent issues to let them self-resolve, conserving time and energy. Rooted in Napoleon’s practice of delaying letters for weeks, the method can reduce needless work in emails, tech issues, or project concerns. Implement by delaying responses (e.g., 24–72 hours) or tailoring who/what to delay, while weighing potential benefits against risks. Benefits include efficiency, encouraging initiative, and avoiding premature optimization. Pitfalls include procrastination, the ostrich effect, and Parkinson’s law. Use with clear deadlines and context; not for urgent or high-stakes matters.

Proves that DOF = 1 (Single Source of Truth) uniquely guarantees coherence among multiple encodings of the same fact; any incoherent system (DOF > 1) yields arbitrary resolutions (Oracle Arbitrariness). In software, facts are structural specs and coherence means consistent encoding across locations; achieving DOF = 1 requires definition-time hooks and introspection, features lacking in most languages. Four theorems: Coherence Forcing, DOF=0 unrepresented, DOF>1 incoherence, Oracle Arbitrariness; an unbounded coherence-restoration gap (O(1) vs Ω(n)). Verifies in Lean 4 and via OpenHCS migration (47 checks → 1).

Review of 414 women with breast cancer found AI-based CAD missed 30.7% of cases. Dense breasts and tumors ≤2 cm were most likely to be missed. When radiologists evaluated diffusion-weighted imaging (DWI) alone, they detected 83.5% (one radiologist) and 79.5% (the other) of the AI-missed cancers. DWI was best for tumors >1 cm or invisible on mammography, suggesting DWI could complement AI as a safety net, though the study's single-center, cancer-diagnosed cohort limits generalizability; prospective multicenter trials are needed.

Cloudflare Radar traced a BGP route-leak in Venezuela on Jan 2, 2026, involving AS8048 (CANTV) leaking prefixes originated by AS21980 (Dayco Telecom) to AS52320 (GlobeNet). Since December there have been eleven AS8048 leaks, suggesting a misconfigured export/import policy rather than malice. The prefixes sit in 200.74.224.0/20, with AS8048 as downstream provider to AS21980 and routes often heavily prepended. The event predates U.S. actions in Venezuela and is unlikely Maduro-related. To reduce such leaks, the post advocates ASPA (RPKI-based) and RFC9234, plus interim measures like Peerlock, and RIPE’s ASPA object creation.

go.sum is not a lockfile and has no effect on version resolution; it’s a local cache for Go's Checksum Database, securing a consistent hash for module versions. The real dependency data lives in go.mod, which since Go 1.17 lists direct and transitive dependencies with exact versions. In Go, go.mod acts as both manifest and lockfile, with semantic versioning and no surprise upgrades. Other ecosystems separate manifest and lockfile; Go keeps it simple with a single human-readable file and mod tooling.

Project Patchouli is an open-source EMR pen tablet hardware implementation and documentation project. It includes a coil array, RF front end, DSP algorithms, and is compatible with pens from multiple vendors to deliver ultra-low-latency input. It documents EMR mechanisms, circuit implementations, signal processing, and pen protocols across product lines. Started Jan 2024; first prototype Mar 2024; docs hosted Jan 2025. Maintainer: Yukidama; contact [email protected]; Discord. NLnet Foundation sponsorship. Licenses: CC BY 4.0 for docs, CERN-OHL-S for hardware, GPLv3 for code. GitLab MkDocs/Read the Docs.

Caroline Crampton’s 2025 recap: she read 121 books (fiction), hit the 120-goal but didn’t broaden beyond her comfort genres; library ebooks grew in use. Her blog, reviews, and reader discussions worked well. Top reads included The Conjure-Man Dies, The Heat of the Day, The Bright Sword, In Muffled Night, The Feast, Death on the Down Beat, Penhallow, Absent in the Spring, and Dagobert Trostler. For 2026 she drops the strict goal, reads more from shelves, seeks variety, reads short stories at bedtime, and starts a writer-focused project with reviews.

Chase will become the new issuer of Apple Card in about 24 months, with Mastercard remaining the payment network. The transition is expected to move over $20 billion of Apple Card balances to Chase, subject to regulatory approvals, and JPMorgan Chase anticipates a $2.2 billion credit-loss provision in Q4 2025 related to the forward purchase. Apple Card will retain no fees, up to 3% Daily Cash, Apple Card Family, ACMI, and a Savings account; Savings is provided by Goldman Sachs Bank USA, while Apple Card is issued by Goldman Sachs Bank USA. Executives from Apple, Chase and Mastercard emphasized the partnership.

Dependabot-core is MIT-licensed, a stateless Ruby library that handles update logic for 25+ ecosystems (parse manifests, check registries, generate file changes). The scheduling, state, and PR coordination live in GitHub’s proprietary infrastructure, so self-hosting requires rebuilding that layer. The project is complex and heavily patched per ecosystem; tests include a fake ‘silent’ ecosystem. Dependabot‑core doesn’t store a vulnerability database; GitHub provides advisories. An open, event-driven coordinator (dependency index + webhooks) could replace polling, but no complete open implementation exists; Renovate uses a similar split with closed-source coordination.

An analysis of 125,183 kernel bug-fix records (Fixes: tags) shows bugs hide in the Linux kernel for an average of ~2.1 years before discovery; CAN bus drivers and SCTP networking linger longest (4.2 and 4.0 years). The longest-lived bugs include an ethtool buffer overflow (20.7 years) and a netfilter refcount leak (19 years). Expanding from 2025-only to full 2005–2025 history lowers the average to 2.1 years and reveals 57% found within a year; 69% found within a year by 2022. VulnBERT achieves 92.2% recall with 1.2% FPR for bug-prone commits, aiding triage.
