Big career moment! 🎉

Years of work, all coming together in one #WWDC26📷 session!

I got to introduce Device Hub today, something my team and I have poured our hearts into!

If you develop apps, you will love this. Check out the session!👇

[Matt Marks @Matt__Marks]

@ualch9 Am so proud of the team, we worked hard on this! Glad you enjoy 🫡

It has been a labor of love bringing this 3D iPhone Duo simulator to life! Try it out now in Xcode 27.1 to prepare your apps for launch day on October 23rd!

(pro tip: hold ⌥ to get hinge slider control)

Xcode 27.1 download:

@ofercraft @andpoul what are you seeing?

[Matt Marks @Matt__Marks]

@josesaezmerino Do you mean macOS screen recordings? Or, do you mean the control at the bottom of the Device Hub window?

[Matt Marks @Matt__Marks]

@austnstuff @plahteenlahti @austnstuff @plahteenlahti what sort of issues are you two hitting?

[Matt Marks @Matt__Marks]

@sama @anabology i’d like to help

@ReeceWoodman @edleonklinger Binary outcomes don’t mean an equal probability of both outcomes.

[Matt Marks @Matt__Marks]

anyone else?

[Matt Marks @Matt__Marks]

@FranzVorenkamp @MengTo It's Device Hub! Announced yesterday - ships alongside Xcode! Check it out: https://t.co/WEy1tAUlHN

[Matt Marks @Matt__Marks]

@sforsethi Yes! Now, you can pair it directly to your Mac - wirelessly!

@wallsbyjfl Full resolution link?

[Matt Marks @Matt__Marks]

@lucidstarfield When will this be available?

[Matt Marks @Matt__Marks]

@benspringwater Gotcha, is there any mode in which it can be used for free without using the AI assistant? I assume that is the main paid value add. I would love to try it without any AI guidance before even starting a free trial.

Immense planning and technical precision was required for this absolutely preposterous (but real) view: I captured my friend @BlackGryph0n transiting the sun during a skydive.

This might be the first photo of it's kind in existence. See a video of this moment in the reply 👇

This is an exaggeration. The authors explicitly treat this as a possible small correction to be folded into future CMB analyses, not a wholesale replacement of the Big Bang signal.

Ahahahaha, the James Webb Space Telescope continues to deliver massive L’s for astrophysics.

A new paper shows that the “Cosmic Microwave Background Radiation” can be explained entirely by the energy of recently discovered Early Mature Galaxies — massive galaxies that the JWST discovered which crushed the existing models of galaxy formation because they formed much earlier than astrophysicists thought possible.

But now these EMGs turn out to account for the entire energy density of the CMB radiation, which was believed to be a “snapshot” of the first light emitted after the Big Bang, when the universe was ~379,000 years old. The variations in the CMB were believed to be relics of quantum fluctuations in the dense plasma of the Big Bang.

If these new findings are accepted (and there’s no reason not to accept them), then all of the following flagship findings of cosmology are thrown into question:

— Big Bang theory: foundational cosmological model undermined
— Cosmic inflation: loses observational justification
— ΛCDM model: key parameters become unreliable
— CMB power spectrum: loses predictive relevance
— Dark energy: inferred from CMB; may be mischaracterized
— Dark matter density: current estimates may be invalid
— Age of the universe: must be recalculated
— Primordial nucleosynthesis: needs alternative explanation
— Hubble constant (H₀): no longer reliably constrained by CMB
— Large-scale structure formation: initial conditions unclear
— Reionization epoch: timing and cause questioned
— Cosmic distance ladder: calibration may be flawed
— ISW (Integrated Sachs–Wolfe) effect: interpretation invalidated
— Acoustic peaks in CMB: no longer evidence of primordial sound waves
— Polarization of the CMB: origin needs reassessment
— Baryon acoustic oscillations (BAO): decoupled from CMB
— Cosmic curvature: flatness inference challenged
— Matter–radiation equality timing: re-evaluated
— Gravitational lensing of CMB: loses standard interpretation
— Planck and WMAP findings: foundational assumptions invalidated

My friends, do not listen to scientists when they act like they have everything figured out and you’re a retard for questioning them. They have abandoned the humility needed for scientific discovery long ago, and it’s only when new findings arrive with shock and awe that their hubris is exposed.
