Isn't this what DNSSEC solves?

Guess the site runs on PHP..

This the most common failure mode I have seen with clocks being widely out of sync. You can't access many online services as the certificates are either dated to future or expired.

Is it really so that Time Division Multiplex timing in cellular networks is based on NTP time? I stopped reading after the article implied this - it doesn't sound plausible at all.

Thank you, that definitely was an interesting read. Sad to learn of Bill Paxton's passing. Clearly his legacy and impact however live on, like this research demonstrates.

It seems he preferred the term "software instrument" to refer to MESA:

> Bildsten and Paxton have taken to calling programs like MESA "software instruments,” according to the latter. “Just like you can’t do observational astrophysics without an instrument like a telescope," he said, "you can’t do computational astrophysics without an instrument such as MESA."

It's amazing what impact one good piece of software, freely available to anyone anywhere to use, can have on a field. I think this quote illustrated the problem he was able to solve very well:

> Ideally, you want to be able to run an experiment, but you can’t go grab a star, run an experiment for a billion years, and come back later to see how it turned out.

Yes, this has to be where the picture originates. Given that almost all maps show the north facing up, picturing the Earth rotating anti-clockwise around the Sun throughout the year makes sense. A bit similar to how clocks for the times of day run clockwise probably because this aligns with the rotation of a sundial placed in the Northern hemisphere. In the Southern hemisphere, a sundial runs anti-clockwise.

Although, converse arguments can be made for both - even if we assume an observer located in the north. If we do indeed picture the Earth rotating in space from the outside - it actually rotates counterclockwise around its axis with the north up. So should day clocks actually run "backwards"? And the "fixed" background of distant stars seem to rotate around a northern observer in the clockwise direction throughout the year - so the image of the year rotating clockwise is just as correct.

Everything seems relative to the prespective chosen.

Right. If viewed with the north pole up, Earth indeed rotates counterclockwise around the Sun. Not sure if it would be any different for someone living on the southern hemisphere though, as all the maps used globally have the North up and the South down.

No but possibly used same schoolbooks. An image or such in an old schoolbook could indeed seed such a visual idea.

Love it!

One weird thing: the author of this clock/calendar portrays the year rotating clockwise (click on the calendar icon in top left to see the "annual" calendar): January in 12 to 1 o'clock, February in 1 to 2 o'clock, etc. and December in 11 to 12 o'clock.

In a poll of some close friends recently, we found out that most of us (>80% including myself) had always mentalized the year rotating counter-clockwise (starting from January at 12 to 11 o'clock, Februay at 10 to 11 o'clock etc. and finally December in 1 to 12 o'clock.)

Bizarely none of us could explain why we had such weird anti-clockwise mental image of the annual cycle, but all who viusalized the year running counter-clockwise said they had done so for as long as they could remember.

What stops you from going to work one hour early, so you get off earlier as well? Most employers these days allow flexible working hours.

And if we are permanently moving our clocks to advance by an hour, why stop at just one hour? Why not have +2h or +3h so we get even more brighter evenings.

This is covered in the article.

Chemical dissolving is only needed for carbon fiber composite. 90% of the resin was cited to be recoverable in this process.

Surely the S&P 500 index regularly closing at all-time-high levels while this "hurting" was unfolding is a valid counterpoint?

Meanwhile, all European stock indices continue to underperform their American counterparts. The return on STOXX Europe 600 index over the past 10 years has been about 58%. The S&P 500 in this same period returned 237%, and more importantly has continued to outperform STOXX Europe 600 throuhgout 2025. Surely investors would be abandoning the US stock market like rats on a sinking ship if Trump was wrecking the US economy?

> Things like that mean that in the future the US won't be able to bully for leverage like they are today.

I would fully applaud this, if it actually does happen. But so far European defence co-operation has been and continues to be weak and incoherent. It is most blatantly apparent in how Hungary and now Slovakia have been able to derail EU-level co-operation in supporting Ukraine.

However I must admit the recent €600 Billion defence package is one rare step to seemingly right direction.

The goal of tariffs is to strengthen your own domestic manufacturing economy. Under high tariff regime, domestic manufacturing gets a pricing advantage over imported goods. The best scenario is if you can get other countries to not place reciprocal tariffs on your goods - meaning foreign companies are disadvantaged in your home market but your companies have uninhibited access to the consumers abroad.

But is that really happening? If that was actually true, Trump would obviously have no leg to stand on. But what we have seen instead is exactly the opposite - countries are scrambling to strike "trade deals" with Trump no matter how terrible terms they get (like the one-way 15% tariff EU "achieved".)

There is really no downside at all for Trump. If it actually starts hurting US economy at any point, he can easily just signal reversing the policy and everyone will let out a big sigh of relief and markets rebound. If it causes some long-term harm for US, he will be long gone by then. But if he is succesful in establishing a new US-first world order he will be forever remembered as one of the greatest American presidents in history.
