CLAUDE HAIKU 5.5 (4 MINUTE READ) [8]

Claude Haiku 5.5 is Anthropic's latest fast and low-cost model. The
model is priced at $0.10 per million input tokens and $0.50 per
million output tokens up to 100,000 tokens, after which the price
increases 5x. Under 100,000 tokens, Haiku is the same price as GPT-6
Luna and reports higher benchmark scores, but above 100,000 tokens,
Luna looks like a much better deal.

THE MATHOCALYPSE (9 MINUTE READ) [9]

OpenAI recently released 372 breakthrough results in the field of
mathematics. However, it appears no human has understood any of the
proofs yet. Experts reading the proofs say the papers are so horribly
written they're impossible to read without AI help. The citations are
also often irrelevant and confusing.

ZUCKERBERG'S BIOHUB PARTNERS WITH DOE, NIH TO INVEST $1.8 BILLION IN BIOLOGICAL DATA FOR AI MODELS (1 MINUTE READ) [10]

Biohub, a nonprofit co-founded by Mark Zuckerberg, is working with
the Department of Energy, the National Institutes of Health, and other
funding partners to invest $1.8 billion in building biological data
ready for AI models. The investment is aimed at providing data sets
that allow researchers to use AI models to find new ways of preventing
and treating diseases. The DOE will invest more than $500 million
across five years in lab measurement, modeling, and computation to
build an AI-ready open data resource; the NIH will coordinate the
contribution of relevant datasets, repositories, and knowledge bases;
and Biohub will work with the NIH to standardize the datasets for AI
model training.

IN VIENNA AND BEIJING, THE FIRST NUCLEAR CLOCKS BEGIN TO TICK (6
MINUTE READ) [11]

Two independent teams in Vienna and Beijing have simultaneously built
the first clocks that keep time by counting the squishing and
unsquishing of the atomic nuclei of thorium. The clocks are so precise
that they only lose one second once every few million years or so.
Nuclear clocks have the ability to search for certain kinds of dark
matter. If a particle of dark matter passes through the thorium
nuclei, it could register as a wobble in the nuclear clock's otherwise
steady tick-tock.

INFLUENCE WITHOUT AUTHORITY (4 MINUTE READ) [14]

Super ICs gain influence by repeatedly doing the unglamorous things.
Over time, making the work better, making the story clearer, and
making it easier for other people to succeed changes how people behave
around you. Authority is a natural side effect of being the person
others rely on. Focus on sharpening your craft, turning ideas into
stories people can retell, packaging your thinking so it travels
without you, and helping your peers hit their goals.

ANTI-PATTERNS IN SOFTWARE BLOGGING (12 MINUTE READ) [15]

Readers need a compelling reason quickly to continue reading. The
reader should be able to read an article from start to finish without
clicking links or hovering for tooltips. Avoid presenting articles as
a follow-up to a previous article. Drop the formality and write the
way you speak in real life. Test articles in mobile view, and use
browser testing tools to find low-contrast text to improve visibility.

Pro. The developer used Claude Opus 5.5 to create the software. The

anything Adobe has ever put out. They claim they will be able to reach
