These small tweaks can make a big impact. The shorts on the left look better because they have a distinctive shape, while the shorts on the right just follow the person's body. Combined with the layer (admittedly not always possible) and improved color combo, outfit looks better.

It was a privilege to participate in Wednesday’s panel at #WebSummit, exploring the tensions between EU regulation and innovation. I emphasized the critical role of innovation at X, which has driven remarkable platform enhancements, especially @grok, to advance free expression and creativity.
A pivotal point: Leveraging the Digital Omnibus to foster a more agile regulatory framework, enabling innovative companies like X to flourish.
I greatly appreciated the insightful dialogue with @McNamaraMEP and @Adina_Portaru
of @ADFIntl on innovation and protection of free speech. And a great shoutout to our moderator @MartaDhanis and to Theo McDonald @tbald101 @WebSummit

Un piacere partecipare ad Actually e grazie mille a Riccardo Bassetto e @RicHaupt per il vostro tempo! Ad Astra!

[Cris Nulli @crisnulli]

Ci è voluto tempo dalla prima conversazione, alcuni mesi fa, con @RicHaupt e Riccardo Bassetto, ma quando un'idea è solida, i progetti prendono forma.

Questo è il caso dell'invito a Federico Paderni @federico come ospite di @actually_pod il format ideale per condividere approfondimenti su X e xAI, una novità per X, con un podcast in Italia.

Federico, grazie al suo ruolo, ha una prospettiva ampia per osservare e analizzare i mercati europei.

Nell'episodio, Federico e Riccardo Bassetto hanno discusso temi come la visione di X come Everything App, le Community Notes, il progetto X Money, l'integrazione tra X e xAI e il ruolo di Grok nell'ecosistema.

Infine, la conversazione si è focalizzata sui "first principles" di X, con un approfondimento su come valutare il potenziale di successo di un'azienda.

Questo aspetto, particolarmente interessante, offre una prospettiva diversa per valutare il futuro successo di un'impresa.

Quindi, per valutare il potenziale di successo futuro di un'azienda, il suo successo attuale ha un'importanza limitata. Allo stesso modo, la velocità con cui il prodotto viene attualmente sviluppato è una variabile di secondaria rilevanza. Ciò che realmente determina il futuro di un'azienda sono la prima e la seconda derivata dello sviluppo del prodotto, ossia il ritmo di progresso e l'accelerazione di tale progresso. Queste due metriche, che rappresentano la rapidità con cui l'azienda migliora e innova i propri prodotti, costituiscono il fattore più critico per prevedere il successo a lungo termine e la competitività nel presente.

Few things on this. Aside from the fact that the Laver Cup court (which Fed presumably has some control over?) plays bizarrely slow compared to most of the elite tournaments on the men's tour, you can have a look at the data to see whether his claim that clay, hard, grass courts all play the same. Looking at one of the slower and one of the faster courts:

Adjusted Ace rate Monte Carlo 2025: 5.3%
Ace Rate Cincinnati 2025: 12.3%

Avg Rally length Monte Carlo 2025: 4.75 shots
Avg rally length Cincinnati 2025: 3.58 shots

CPI Monte Carlo: 29
CPI Cincinnati: 43

The ace rate and rally lengths are meaningful differences that hold up across the last few years on different surfaces. Comparing grass to clay, Wimbledon's 10 year adjusted ace rate (approx 12%) is very different to Roland Garros (approx 6%). Surfaces still do create differences, especially because they all take spin quite differently and spin rates are massive right now

Players are also making adjustments from surface to surface and playing differently, you can see that in slice rates, return strategy etc:

I think part of the issue is that the dominant play styles that have emerged in this generation (Alcaraz and Sinner) are genuinely very, very effective on both slow and fast courts. Alcaraz and Sinner are both complete players with few imbalances, but both of their key skills - serve, forehand/backhand+1, and return - are so good in combination and are so sustainable that their optimal strategy is to start blasting as early as possible in the point. They simply don't need quite a lot of the rest of their skillsets that often in order to beat the field

It's obviously true that some courts were slowed after the 90's servefest, probably peaking in slowness in the 2007-2014 period. But multiple courts have also gotten quicker since then and the vast majority of points are over very, very quickly. Long rallies are a small minority at the top of men's tennis on every surface (approx 70% of points are over in the 0-4 shot range). It's far from certain that massively slower courts would produce longer points given how much power the current players have, nor that massively faster courts would produce much shorter points (we're already at a very low avg. rally length on many hard courts), nor more variation (serves and forehand+1's are already hugely dominant, especially on quicker courts, leaving little room for variation of playstyles). You can even argue that it's actually slower courts where we see more variation at the moment, just consider the matchup differences and all court tennis differences (RG final featured a higher net point rate than the US Open final for e.g) between Alcaraz and Sinner at Roland Garros (slow court) this year vs their US Open final (medium fast court)

Also the bit about tournament directors wanting the best players in the finals is fine and has always been true. Shouldn't the biggest tournaments be won by the best players? To a degree you *do* want to decrease variance when determining who the best is in a skill sport. I never understood why this is controversial.

Federer is obviously right that the courts are more similar than they should be. We should have more genuinely quick courts and more genuinely slow courts to at least try to encourage playstyle diversity (Indian Wells is the only medium slow rated court left at the top level of men's tennis in 2025, there are no slow rated hard courts at Masters/Slam level). What we have instead is a bunch of medium fast hard courts from the Australian Open to Miami, to Cincy, to the US Open, to, Paris, to the ATP Finals (which has an avg ace rate of 15% in last 4 years btw). Plus a bunch of inconsistent and occasionally dead balls (although rumours are that some of the ball issues have been, or are being, solved).

As always I think this debate is sort of stuck in 2016 rather than 2025. Court speeds have changed quite a bit in recent years, and so have the dominant playstyles of the leading players (Alcaraz and Sinner). Ignoring both these things makes debate on this nearly impossible

The algorithm will be purely AI by November, with significant progress along the way.

We will open source the algorithm every two weeks or so.

By November or certainly December, you will be able to adjust your feed dynamically just by asking Grok.
