Article Summary (Model: gpt-5.2)

Subject: Windows 11 broke trust

The Gist: The author argues Microsoft’s Windows 11 has become unreliable and user-hostile due to forced updates, regressions, ads/upsells, and poor responsiveness—culminating in severe post-24H2 bugs that made their system unstable. After failed rollbacks/reinstalls and vendor blame games (Microsoft vs NVIDIA), they switched to Linux (CachyOS) despite initial rough edges, because it was fixable and felt faster. They replaced Windows-only music tooling (Ableton) with Bitwig, leaned on modern Linux audio (PipeWire), and claim Linux in 2026 is viable for dev work and most gaming except kernel anti-cheat titles.

Key Claims/Facts:

  • 24H2 instability: A Windows 11 24H2 update allegedly installed without consent and introduced severe Chrome rendering/freezing issues; an Insider build reduced one bug but introduced another.
  • Vendor blame & MPO: The author links Chrome video freezes/flicker to a Microsoft–NVIDIA incompatibility around the Multiplane Overlay pipeline, with neither side providing a clear fix.
  • Linux tradeoffs & gains: CachyOS had sleep/NVIDIA issues but was solvable via configuration; Bitwig + PipeWire provided workable music production with low latency; overall desktop operations felt noticeably faster than Windows.

Discussion Summary (Model: gpt-5.2)

Consensus: Cautiously Optimistic—many sympathize with “Windows is getting worse,” but disagree on root causes and how universal the problems are.

Top Critiques & Pushback:

  • “It’s your corporate image, not Windows”: Several argue Explorer/context-menu lag is often caused by endpoint management/DLP, AV, OneDrive/SharePoint/Teams integrations, and shell extensions rather than Windows 11 itself (c46800178, c46803478, c46797782).
  • “No, Windows 11 really is janky”: Others counter that the slowness is reproducible on clean/personal installs or even retail demo machines, and that Win11 UI changes (new context menu, animations, search) add latency/regressions (c46803099, c46800569, c46803099).
  • Linux isn’t frictionless either: Commenters note Linux pain points around GPU/driver lifecycle, sleep/Wayland/X11 quirks, DPI scaling, UI framework fragmentation, and certain workflows (e.g., Teams/Zoom video, VR) (c46796376, c46796496, c46796858).

Better Alternatives / Prior Art:

  • Faster Windows utilities: People cite third-party tools that outperform built-ins—Everything Search for file search (c46801043) and alternative file managers like FilePilot (c46798825), plus older “snappy” software examples as evidence performance is a choice.
  • “Just use macOS/ChromeOS/clean install”: Some suggest Macs (less OEM crapware), Chromebooks, or wiping corporate bloat to restore performance (c46805375, c46802412).

Expert Context:

  • Windows “tiny files” tax: Developers point out Windows historically struggles with many small files (e.g., node_modules, .git), and cloud-syncing them (OneDrive) can amplify pain (c46803760, c46803478).
  • Gaming caveat is anti-cheat: The main Linux-gaming blocker is kernel-level anti-cheat in popular competitive titles; non-kernel or enabled EAC/BattlEye games may work, but it’s developer-controlled (c46797961, c46797047, c46798540).
  • Updates & control as the core grievance: Beyond speed, many say forced updates/ads and “fighting the OS” drove them away, while some note workarounds exist but resent needing them (c46796669, c46797269, c46800316).

#2 Airfoil (2024) (ciechanow.ski)

summarized
105 points | 15 comments

Article Summary (Model: gpt-5.2)

Subject: How Wings Make Lift

The Gist: An interactive, simulation-heavy walkthrough of airfoil aerodynamics that builds from microscopic particle motion to macroscopic flow fields. The article explains how pressure variations arise from constraints (no penetration, steady flow) and how these pressure gradients steer air around an airfoil, producing net forces. It connects lift and drag to surface pressure distributions, shows how angle of attack creates asymmetric pressure and lift, and then introduces viscosity, boundary layers, adverse pressure gradients, flow separation, and stall. It closes with how changing airfoil shape targets different tradeoffs (drag, laminar flow, transonic effects).

Key Claims/Facts:

  • Pressure gradients drive flow: Spatial pressure differences accelerate/turn air; surface pressure integrated over the airfoil yields lift and pressure (form) drag.
  • Angle of attack & stall: Increasing angle of attack increases lift until separation and stall reduce lift; separation is tied to boundary-layer behavior under adverse pressure gradients.
  • Viscosity & boundary layers: No-slip + viscosity create boundary layers; laminar vs turbulent layers trade skin-friction drag against resistance to separation, shaping real airfoil design choices (e.g., laminar-flow, supercritical profiles).

Discussion Summary (Model: gpt-5.2)

Consensus: Enthusiastic.

Top Critiques & Pushback:

  • “Pressure vs momentum” framing: One commenter argues the post over-emphasizes pressure differentials and that lift should be explained primarily via flow deflection / momentum change, with pressure as a consequence (c46805298). Others push back that these are complementary descriptions: the wing’s force is experienced through surface pressure, and pressure differences are linked to turning the flow (c46805954, c46811968).
  • Some explanations feel hand-wavy: A reply says parts of the referenced explanatory material (a linked lecture/video) gloss over why pressure is higher under the wing, and wishes it started from measured pressure distributions (c46811907).
  • Meta / housekeeping: Minor confusion about the year in the title (it’s a 2024 article), and notes about the author’s posting cadence (c46796062, c46799307).

Better Alternatives / Prior Art:

  • AeroSandbox / XFOIL / CFD tooling: For readers who want to “play with aerodynamics,” one commenter recommends AeroSandbox, noting it can run fast estimates (including neural-network models) and compares it to heuristic solvers like XFOIL and slower CFD approaches (c46799442).
  • Joukowski airfoil math view: A commenter points to a complex-analysis/Joukowski-transform explanation as a “pure-math” perspective on airfoils (c46808713).
  • NASA educational explanation: The pressure-vs-deflection debate references NASA’s educational material emphasizing turning flow/momentum while noting pressure forces (c46805298, c46805954).

Expert Context:

  • Equivalence of lenses: Several comments stress that “momentum change” can be a useful control-volume accounting, but the actual distributed forces on the wing are pressure (and shear) over the surface—two consistent ways to describe the same physics (c46811968, c46805954).

Community Notes:

  • Many comments are straightforward praise for Ciechanowski’s interactive teaching style, with calls to support the author (Patreon link shared) (c46801461, c46809226). A prior, larger HN discussion thread from Feb 2024 is also linked (c46796027, c46801245).

Subject: Verification Layer for Browser Agents

The Gist: Sentience provides a verification layer for browser agents using structured snapshots (roles, text, geometry) and Jest-style assertions to gate steps, ensuring reliability over intelligence. Demonstrated on Amazon shopping flow (search ThinkPad, add to cart, checkout), it enables small local LLMs like Qwen 2.5-3B executors with DeepSeek planners to succeed (7/7 steps), reduces tokens ~43% via filtering, and produces explicit failures with artifacts instead of silent drift.

Key Claims/Facts:

  • Structured Snapshots + Assertions: Predicates like url_contains or exists(selector) verify post-action state deterministically.
  • 3-Model Stack: Planner generates steps/verifications; executor picks CLICK/TYPE; verifier gates success with overrides.
  • Local Autonomy Benchmark: Cloud baseline to full local (11k tokens, 405s) shows verification makes small models viable.

Top Critiques & Pushback:

  • Dismissive: User calls it "slop shit discussing slop shit" (c46796707).
  • Accessibility Tree: Browser exposes accessibility tree (sufficient for vision-impaired, thus AI agents); suggests using it over raw DOM for fairness (c46796505).

Expert Context:

  • Post author clarifies intent: reliability via explicit post-conditions/assertions (not replacing Playwright/Selenium or relying on vision); steps gate with e.g., runtime.assert_(all_of(url_contains("checkout"), exists("role=button"))); fails deterministically with artifacts (c46790507).

Article Summary (Model: x-ai/grok-4.1-fast)

Subject: Package Management Wicked Problem

The Gist: Package management exemplifies "wicked problems" as defined by Rittel and Webber in 1973: issues without definitive formulation, stopping rules, or objective tests, where solutions create new problems and stakeholder goals conflict. The author applies all 10 characteristics to explain slow progress despite massive scale (millions of packages, trillions of downloads), advocating participatory planning and shared protocols over perfect tools.

Key Claims/Facts:

  • No definitive formulation: "Package management" means different things (e.g., npm vs. apt); naming units (package/module/crate) encodes assumptions.
  • No stopping rule: Tools like npm (v10+), Bundler (since 2010) keep evolving; work stops due to burnout or new tools, not completion.
  • Irreversible consequences: Design choices like namespace-less PyPI enable typosquatting; fixes break ecosystems, accumulating unremovable cruft.

Discussion Summary (Model: x-ai/grok-4.1-fast)

Consensus: Thought-provoking analysis appreciated, with users agreeing on challenges like naming and feature creep but debating if it's truly "wicked" or more a thankless task with defined patterns (c46796393).

Top Critiques & Pushback:

  • Naming overload: "Package management" confuses system (apt/pacman) vs. language-specific (npm/Cargo) tools; internal ontologies vary (c46796038, c46796235).
  • Cultural, not technical: Rigorous languages have solid tools; others lag due to culture, not tech—hindsight helped Cargo (c46796424, c46796481).
  • Feature creep/NIH: Kills progress; young Cargo succeeded by being opinionated, but mixes languages create messes (c46795953, c46796156, c46796741).

Better Alternatives / Prior Art:

  • Nix: Solves version hell by trading storage for reproducibility (c46796178).
  • Unified mechanics: Separate policy from core package manager; no need for language-specific ones (c46796688).

Expert Context:

  • Author Andrew Nesbitt's series on package managers praised, including Jepsen-style testing ideas (c46796200).

Subject: DWM-Inspired Tmux Pane Manager

The Gist: dwm.tmux brings dwm's tiling window management to tmux panes, enforcing a layout with a large main pane (index 0) on the left and a stack of smaller panes on the right. It provides intuitive Meta-key bindings for pane creation, movement, rotation, zooming, floating, and window management, plus customizations via environment variables and config.

Key Claims/Facts:

  • Tiling Layout: Main pane left (~mfact% size), stack right; refreshes to this with Meta-t.
  • Key Bindings: Meta-n/w for new panes (same dir option), Meta-j/k cycle, Meta-Enter zoom, Meta-Space float.
  • Installation: Makefile-based; source config in ~/.tmux.conf; requires tmux >3.2.

Discussion Summary (Model: x-ai/grok-4.1-fast)

Consensus: Mildly positive but skeptical—intriguing code and bindings appreciated, yet questioned for added value over custom tmux setups.

Top Critiques & Pushback:

  • Unclear benefits: Little visible advantage over tmux defaults or personal configs; screenshot unconvincing, no floating panes evident (c46795690, c46796641).
  • Tmux suffices: Keyboard controls customizable and fun to tweak yourself (c46796583, c46796649).

Better Alternatives / Prior Art:

  • abduco + dvtm: For session management and multiplexing (c46795717).
  • zmx.sh: Terminal session rehydration alternative (c46796035).

Expert Context: Users highlight useful functions like spawning panes in current directory (c46796641); one excited by "ed" usage in screenshot (c46795745).

Subject: WhatsApp's Rust Media Security

The Gist: WhatsApp rewrote its C++ media consistency library "wamedia" in Rust to improve memory safety against malware in shared files, inspired by vulnerabilities like Stagefright. They developed it in parallel with differential fuzzing for equivalence, overcame binary size and build challenges, and rolled it out to billions of devices across Android, iOS, Web, and more—replacing 160k LOC C++ with 90k Rust LOC—claiming the largest global Rust library deployment.

Key Claims/Facts:

  • wamedia in Rust: Memory-safe library detects malformed media to protect against OS vulnerabilities.
  • Parallel Development: Differential fuzzing and tests ensured compatibility before full rollout.
  • Kaleidoscope Checks: Scans for non-conformant files, spoofing, and risky types like PDFs with scripts.

Discussion Summary (Model: x-ai/grok-4.1-fast)

Consensus: Enthusiastic about the parallel rollout and scale, with praise for differential fuzzing and LOC reduction, though some view the post as PR-like.

Top Critiques & Pushback:

  • Binary Size: Initial Rust stdlib bloat addressed via build optimizations, LTO, or no_std; minor vs. app's 170MB size (c46794278, c46795968, c46796599).
  • Bug Compatibility: Rewrites risk breaking implicit handling of malformed files; fuzzing key for parsers (c46793617).
  • Article Quality: Watery PR/recruitment piece lacking details on C++/Rust integration or supply-chain security (c46795632).
  • Trust Issues: Skepticism on Meta's E2EE claims and data practices (c46796187, c46794497).

Better Alternatives / Prior Art:

  • Android's extensive Rust use exceeds WhatsApp's deployment (c46793579).

Expert Context:

  • Rust benefits extend beyond memory safety to no UB and stronger types (c46795418).
  • Panics should be for impossibles, not expected errors (c46796683).

Article Summary (Model: gpt-5.2)

Subject: AI LaTeX Research Workspace

The Gist: Prism is OpenAI’s free, cloud-based, LaTeX-native writing and collaboration workspace for scientists, with GPT‑5.2 integrated directly into the document workflow. It aims to reduce the fragmentation of research writing (editor/LaTeX compiler/reference manager/chat) by letting researchers draft, revise, reason about equations/citations/figures, and collaborate in one place—without local LaTeX setup. Prism is available now to ChatGPT personal account holders, with Business/Enterprise/Education availability planned.

Key Claims/Facts:

  • AI-in-the-document: GPT‑5.2 operates with access to the paper’s structure, surrounding text, equations, references, and context to make in-place edits.
  • Research workflows: Includes literature search/incorporation (e.g., arXiv), equation/figure/citation refactoring, and converting whiteboard diagrams to LaTeX.
  • Collaboration + access: Unlimited projects and collaborators; free to start, with more advanced features intended for paid ChatGPT plans later.
Parsed and condensed via gpt-5-mini-2025-08-07 at 2026-01-28 05:06:26 UTC

Discussion Summary (Model: gpt-5.2)

Consensus: Skeptical (with pockets of cautious optimism about genuine writing/collaboration benefits).

Top Critiques & Pushback:

  • Name/branding controversy (“PRISM”): Many react negatively to “Prism” because of the NSA PRISM surveillance program, arguing it’s a bad privacy-associated brand for OpenAI specifically; others say it’s a generic word and the association is niche or faded (c46792035, c46795425, c46793165).
  • DDoS on peer review / “slop” externalities: Editors/reviewers worry AI-assisted writing lowers the cost of producing plausible-looking submissions, shifting the burden to unpaid reviewers and overwhelming journals—analogous to AI-generated bug reports/PRs (c46785750, c46787976, c46786432).
  • Trust, data, and incentives: Some are uneasy using a free OpenAI-hosted tool for research writing, suspecting monetization via capturing high-quality drafts and workflows, or at least reinforcing “collect it all” perceptions (c46791690, c46801172, c46795425).

Better Alternatives / Prior Art:

  • Overleaf (and self-hosting): Repeatedly cited as the incumbent for LaTeX collaboration; some note it’s open source/partially self-hostable and already covers much of the workflow (c46784691, c46785608, c46791856).
  • Typst: Mentioned as a preferred alternative to LaTeX for some writers; calls for Prism/others to support it (c46796138, c46786985).
  • Direct LLM use (Claude/ChatGPT): Some say using Claude directly is easier/faster than Prism; others argue Prism’s “review changes” flow may be more responsible than copy/paste (c46793564, c46785934).

Expert Context:

  • Why the ‘bullshit asymmetry’ is hard: One commenter ties Brandolini’s law to the lack of a clear spec for “good paper,” making review/judgment inherently expensive even if some kinds of verification can be cheap (c46789389).
  • LaTeX collaboration rationale: Multiple users emphasize Overleaf-style collaboration and consistent build environments as the real value—more than “just install LaTeX” (c46786338, c46787021, c46793923).

Subject: Claude Coding Revolution

The Gist: Andrej Karpathy shares his shift to 80% AI-agent coding (Claude/Codex) from manual, now "programming in English." He notes massive workflow changes, agents' tenacity removing stamina bottlenecks, productivity expansions, and increased fun by offloading drudgery, despite fallible junior-dev-like errors needing IDE oversight.

Key Claims/Facts:

  • Agents' Tenacity: Relentlessly iterate without fatigue, enabling complex tasks (e.g., looping to pass tests).
  • Leverage Loops: Success criteria (tests, optimization) drive self-improving iterations over imperatives.
  • Atrophy Risk: Manual code writing skills declining; discrimination (reviewing) persists longer.

Discussion Summary (Model: x-ai/grok-4.1-fast)

Consensus: Cautiously optimistic about productivity gains but skeptical due to widespread fears of brain atrophy, tech debt, and skill complacency.

Top Critiques & Pushback:

  • Brain Atrophy: Users report shallow code understanding, forgetting designs, and quitting fights against AI biases after iterations (c46784594, c46788537, c46789379).
  • Tech Debt/Slop: AI generates bloated, inconsistent code; industry risks "slopocalypse" with unmaintainable messes (c46790702, c46791130).
  • Dependency Treadmill: LLM skills depreciate with model changes; rented tools risk shutdowns unlike owned skills (c46786935, c46794408).

Better Alternatives / Prior Art:

  • Local Models: Essential backups if cloud providers fail; run on efficient hardware like Mac Studio (c46796208, c46796385).
  • Structured Prompts/Tools: AST parsing for context, specs like OpenSpec to combat rot (c46793527, c46795477).

Expert Context:

  • Builders vs Coders: AI splits engineers—builders love outcomes, coders miss process; generalists may thrive (c46774862, c46784440).

Article Summary (Model: gpt-5.2)

Subject: Oldest wooden tools

The Gist: Two new studies report exceptionally preserved, very old non-stone tools in Europe: ~430,000-year-old handheld wooden implements from Marathousa 1 in southern Greece, and a ~500,000-year-old hammer made from elephant/mammoth bone from Boxgrove in southern England. Researchers argue these finds show Middle Pleistocene hominins (likely early Neanderthals or Homo heidelbergensis) used a wider range of materials and more specialized techniques than the surviving stone record alone usually reveals.

Key Claims/Facts:

  • Marathousa 1 wooden tools: Two worked wood objects (including an alder digging-stick-like shard, plus a carved poplar/willow twig) were identified via microscopic analysis and CT scans; dated to ~430 ka (Middle Pleistocene).
  • Boxgrove bone hammer: A ~4-inch triangular bone fragment with repeated impact damage and embedded flint suggests use as a knapping hammer; dated to ~500 ka and revises assumptions about when/where European elephant-bone tools appear.
  • Preservation/visibility bias: The article emphasizes that wood and other organic tools are rarely preserved or recognized, so the archaeological record likely undercounts early non-stone technologies.

Discussion Summary (Model: gpt-5.2)

Consensus: Cautiously Optimistic—people find the preservation and dates fascinating, but many push back on the article’s framing as if toolmaking itself is newly pushed back.

Top Critiques & Pushback:

  • Headline/subheading is misleading: Multiple commenters stress that tools (especially stone) are millions of years old; what’s notable here is wooden tools in a secure context and preservation, not “earlier than archaeologists thought” in general (c46782017, c46789007, c46790869).
  • Journalism vs archaeology framing: Users dislike wording that implies archaeologists were “wrong,” arguing archaeology reports what survives and can be validated; absence of evidence isn’t evidence of absence (c46785394, c46788356).
  • Speculative side-discussions get challenged: A thread linking human evolution to “genocidal tendency” is criticized as unsubstantiated and as misusing terms compared to how primatologists discuss intergroup violence (c46783652, c46784502, c46788671).

Better Alternatives / Prior Art:

  • Earlier tool industries and evidence: Commenters cite Oldowan (~2–3 million years), even earlier stone tools (~3.3 million years), and prior indirect woodworking evidence (phytolith/microwear) far earlier than 430k years (c46782017, c46782045, c46782235).
  • Prior wooden finds: Users point to older wooden structural woodworking (e.g., Kalambo Falls ~476k years) to contextualize “oldest wooden tools” vs “oldest woodworking” (c46787530).

Expert Context:

  • “Secure context” matters: One detailed comment explains why the claim is specifically about the earliest handheld wooden tools with secure excavation/dating context, contrasting it with much older evidence of woodworking that doesn’t survive as artifacts (c46789007).

Subject: Geometric Golden Ratio Construction

The Gist: Describes a graphical method to derive the Golden Ratio (φ) by inscribing an equilateral triangle in a circle and drawing a chord through the midpoints of the triangle's sides, as shown in an animated GIF.

Key Claims/Facts:

  • Equilateral Triangle: Inscribed in a circle.
  • Midpoint Chord: Line connecting midpoints of the triangle sides.
  • Derives φ: Ratio emerges from the geometry.
Parsed and condensed via gpt-5-mini-2025-08-07 at 2026-01-28 15:51:07 UTC

Discussion Summary (Model: x-ai/grok-4.1-fast)

Consensus: Enthusiastic about the neat geometric derivation of the Golden Ratio.

Top Critiques & Pushback:

  • No computational edge: Geometric construction offers no numerical stability or rendering advantages over direct algebraic computation (1 + √5)/2 (c46796413, c46796498).
  • Overhyped in design: Many view Golden Ratio as intellectual curiosity rather than practical toolkit; prefer thirds, harmonics, or root rectangles for composition and layouts (c46793531, c46794555, c46794504).

Better Alternatives / Prior Art:

  • Euclidea game: Interactive app for geometric proofs like this (c46791059).
  • Algebraic solve: x² - x - 1 = 0 yields φ and its conjugate (c46792591).
  • UI spacing: Liftkit library uses φ for proportions; Tailwind variant available (c46791810, c46794519).

Expert Context:

  • Pentagon link: Golden Ratio enables straightedge-compass pentagon construction (c46791178).
  • Continued fractions: Videos by Mathologer and Numberphile explain φ as limit (c46792656, c46794105).

Article Summary (Model: x-ai/grok-4.1-fast)

Subject: Pandas 3.0 Released

The Gist: Pandas 3.0 brings major enhancements: default dedicated 'str' dtype for strings (better perf/safety via pyarrow), Copy-on-Write (CoW) for consistent behavior (no more SettingWithCopyWarning, chained assignments fail), microseconds default for datetimes (avoids bounds errors), and pd.col() syntax. Breaking changes from deprecations; test with 2.3 first, install via pip/conda.

Key Claims/Facts:

  • String dtype: Auto-infers 'str' over 'object' for perf/type safety.
  • Copy-on-Write: Indexing returns copies; use .loc for safe mods.
  • Datetime: Defaults to input/microsecond resolution, not ns.

Discussion Summary (Model: x-ai/grok-4.1-fast)

Consensus: Respectful nod to Pandas' pioneering role, but skeptical upgrade; many prefer Polars/DuckDB for speed/modernity.

Top Critiques & Pushback:

  • Outpaced by Polars: Inferior API, speed, memory, no lazy/OOM; compatibility constrains (c46794158, c46794432).
  • Breaking changes risky: Timestamp ns-to-us shift problematic; CoW good but painful (c46795161).
  • Ecosystem lock-in: Third-party libs Pandas-only (c46795757).

Better Alternatives / Prior Art:

Expert Context:

  • Pandas from finance/Excel replacement, built Python data stack despite warts (c46795685, c46796681).
  • Polars iterates on Pandas/R mistakes (c46796289).

Subject: SKA's Precursors Shine

The Gist: The Square Kilometre Array (SKA), set for science observations in 2028, builds on 30 years of development via precursor telescopes in South Africa (MeerKAT, HERA) and Australia (ASKAP, MWA). These have delivered breakthroughs like detailed Milky Way center images revealing 10x more radio filaments, Epoch of Reionization signals, new radio transients, odd radio circles, and fast radio burst studies, while facing satellite interference challenges.

Key Claims/Facts:

  • MeerKAT: Produced clearest galactic center image with abundant 150-light-year filaments (origin unknown).
  • HERA/MWA: Probe primordial hydrogen reionization and discover repeating radio transients every 18 minutes.
  • ASKAP: Surveys millions of radio sources, maps "missing" baryonic matter via FRBs, finds mysterious radio rings.

Discussion Summary (Model: x-ai/grok-4.1-fast)

Consensus: Enthusiastic about SKA precursors' achievements and radio astronomy history (12 comments).

Top Critiques & Pushback:

  • Satellite interference: Precursors like ASKAP, MeerKAT, MWA detect background radio noise from constellations, a growing issue for SKA.

Expert Context:

  • MRAO prototypes: UK site hosts SKA-Low/HERA prototypes; historical Interplanetary Scintillation Array discovered first pulsar; 1957 38 MHz galactic survey vs. modern MeerKAT 1.28 GHz image shows vast improvement (c46794954, c46795012).
  • Filaments overlooked: Users question why 150-light-year galactic filaments aren't bigger news (c46796168).
  • Data challenges: SKA may handle up to 20 Tb/s data rates (c46793836).
