pgalvin··on Satellite Tracker – Live Map of Starlink and 30k Satellites
I believe the second half of your comment is exactly what I was getting at.
pgalvin··on Satellite Tracker – Live Map of Starlink and 30k Satellites
I’m more familiar with how Starlink compares to existing publicly-available satellite internet options. Here are some brief points:

- data throughput orders of magnitude higher,

- the ability to use smaller and more portable antennas (e.g. ~100 Mbps with something the size of a textbook, currently ~2 Mbps and soon ~10s Mbps with your normal mobile phone),

- order of magnitude lower latency compared to GSO satellites.

Other constellations like Iridium dedicate large portions to use by government(s?), too, but simply do not have the throughput or total bandwidth that Starlink does. Your speeds there, on the expensive business plans that offer it, are measured in the low Kbps.

However, the Earth’s own radius dwarfs the height of LEO, so they’re actually roughly the same.

There are other reasons we don’t currently experience major problems with collisions in space, and why airplanes sometimes do, but it is not this.

pgalvin··on EU commissioners shut down air conditioning for employees, leave theirs on
The article indicates they were unable to handle the increased electricity load, which caused blackouts.

Additionally, sometimes unnaturally high temperatures break AC systems put in place with poor planning. This is very common in UK supermarkets every summer.

pgalvin··on David Attenborough's 100th Birthday
He is far more than just a narrator. His 77-year career created and defined the wildlife/nature documentary as a genre, beginning at a time when television was so new that it really was just him and a few individuals making all the decisions. In his youth, he was given some cash and sent to travel the world in a 2-3 man team, off-grid for months, in the “Zoo Quest” series - the first time anyone had really seen animals, in the wild, on television.

Switching to a desk job, he went on to use his position in the BBC to green-light then-pioneering documentaries like “Civilisation” and “The Ascent of Man” (and still travelled occasionally for anthropological and nature documentaries, that he also green-lit) that remain a huge influence on all documentaries today.

Then in 1979, “Life on Earth” created an entirely new format of nature documentary that has only seen iterative change in the almost-50-years since. The rest, as they say, is history. He’s been heavily involved in the production of so many documentaries in the decades since, only reducing his role as he got older. Even in his 90s most of the series he narrates have short on-location sequences with him.

It’s safe to say that he, perhaps more than anyone else, created the “nature documentary” - both in experimenting with the format, and in green-lighting shows - and therefore shares a huge amount of responsibility for the many positive second order effects. Certainly in the UK, I would argue that a significant amount of public awareness of climate change comes from BBC documentaries. As attested to by others in this thread, generations of scientists and conservationists pursued their professions in part because they were inspired by him (and I can throw my own hat in the ring for this). It was also spoken about, at his 100th birthday concert, what an outsized influence his documentaries had on increased worldwide awareness of plastics pollution and the recent UN treaty beginning to address it.

His voice, really, is secondary to all that.

(I would highly recommend reading his “Adventures of a Young Naturalist” and “Journeys to the Other Side of the World” books for anyone with an interest in this sort of thing. They’re combined volumes of books he wrote back in the 1950s and 60s about his Zoo Quest expeditions - both a wondrous first-person view of the travels and interactions with wildlife, but also a fascinating teleportation back in time into a world where air travel and television were brand new, and all of these remote communities were near-untouched compared to today).

pgalvin··on If America's so rich, how'd it get so sad?
I disagree with the claim that a greater proportion of people go hungry, and more are homeless, today than at any point in recent western history. These have broadly been on a downwards trend over the last century.

Of course many do struggle, and that should not be dismissed by pointing to the past. But it nonetheless strikes me as naive to believe that people today are hungrier than at any point in recent history - the obesity crisis, and its lack of discrimination between social classes, should at least in part demonstrate this.

In my opinion, such exaggerations mostly serve to discredit and distract from legitimate complaints about the cost of living today.

pgalvin··on Artemis II and the invisible hazard on the way to the Moon
I believe that is the same event as in my comment.
pgalvin··on Artemis II and the invisible hazard on the way to the Moon
> Imagine you take a conspiracy influencer and actually put them in the spacecraft with the astronauts so they could see the whole thing with their own eyes and wouldn't be able to deny it. They return to earth to tell their followers that it's all real. Do you think everyone will be convinced, or would they say he's now in on the conspiracy and find a new person to lead the conspiracy theory?

https://en.wikipedia.org/wiki/The_Final_Experiment_(expediti...

"The participating flat Earthers all admitted that the midnight sun was a real phenomenon. The larger flat Earth community has largely rejected the results and accused the participants, including the flat Earthers, of having faked the expedition and of being part of a larger conspiracy to promote the spherical Earth model."

Could you expand on this please?

pgalvin··on NHS staff refusing to use FDP over Palantir ethical concerns
Your entire comment is filled with false claims and figures.

In 2025-26 there are an estimated 39.1 million people paying income tax - 56.0% of the population [1]. Of course, in the last census, 20.7% of the population were children [2]. About 3.1% of the population are UK students in University education [3], and about 18.6% of the population are retired [4]. I've also missed all the 18-year-olds in their final year of school, which is roughly 1.1 million or 1.6% of the population [5]. About 8.8 million, or 12.6%, are pensioners who pay income tax that I have double counted, usually due to private pensions and other sources of income [6].

Totally these numbers gives a rough estimate that suggest only about 12.6% of working age people do not pay income tax. This is in line with the government's own statistics putting those claiming Universal Credit at 10.6% of the population [7], or those economically inactive at 12.9% [8]. This is wildly different to your implication that 61% of people are too lazy to work.

Unemployment, which is roughly defined as those out of work who are actively looking for work, is at 5.2% [9], which it is worth noting is slightly below the EU and Euro area average of 5.9% and 6.2% respectively [10]. Direct comparisons are difficult to make, but it is certainly indicative of the UK falling within what is considered a healthy range.

Furthermore, take-home pay on a £100,000 salary is £68,561 [11], giving an effective income tax of 31.4% - far below your claim of 71%. True, there is the so-called "£100k tax trap" which gradually reduces your tax-free allowance above this salary. But this still gives just a 37.6% tax on £125,000, or 41.1% on £200,000. You may consider these to be high, but they are far, far below your claim of 71% income tax.

pgalvin··on iPhone 17e
This depends entirely on how you hold your phone in your hand. For some positions, someone would need a 5” thumb to reach the corner. You can’t make such sweeping statements for something with such variation.

pgalvin··on Dark web agent spotted bedroom wall clue to rescue girl from abuse
You are wrong, this same story was not reported more than ten years ago. The article is not a report of a man being arrested, tried, and sentenced (doubtless the extent of reporting in local news when it happened). This article is about the wider background of one story, of many, from a behind-the-scenes documentary that has been filmed over the last five years and just released.

Did Britain's public broadcaster decide, half a decade ago, to begin making this documentary so that they could secretly and nefariously support a US government agency long before it was embroiled in its current controversies?

pgalvin··on Dark web agent spotted bedroom wall clue to rescue girl from abuse
Are you suggesting that the BBC, the world service arm of a British public broadcaster (that is editorially independent from the state and even the wider BBC), began spending five years filming a documentary across the US, Portugal, Brazil, and Russia, just so that they could secretly support a US government agency half a decade before it became embroiled in controversy?
pgalvin··on Data centers in space makes no sense
Do you mean to suggest that computer hardware does not need to be cooled when it is in space? Or that it is trivial and easier to do this in space compared to on Earth? I don’t understand either claim, if so.
pgalvin··on iCloud Photos Downloader
This will let you download all of your photos that already exist on iCloud Photos.

Going forward, you’d want to set up some other way to sync photos you take from your phone to your other devices. I can personally recommend Synology Photos for simplicity[1], or Immich[2] for an open-source (and in my opinion, slightly better) alternative you can run on any hardware, if you’d like to set up an always-on NAS. These are “Apple Photos” or “Google Photos” equivalents that you host yourself.

Alternatively, something like Syncthing[3] is a dead-simple way to sync your photos to various other devices as and when they are online, if you’d prefer to manage your photos in an ordinary file manager.

I’d be remiss not to mention that, for any solution where you move off the cloud to a central storage location of your own, you really must make backups to keep your photos safe. The 3-2-1 rule is a standard recommendation.

pgalvin··on The eight ways that all the elements in the Universe are made (2021)
The s-, i-, and r-processes do however follow the same mechanism at the most fundamental level, even if it results in wildly different production paths. I think the author was simplifying for an audience unfamiliar with the details, for whom this distinction is less important.

(And I say that despite my own work and usual eagerness to tell people all about it!)

pgalvin··on The eight ways that all the elements in the Universe are made (2021)
I believe it’s quite common for people to marvel at the vastness of the universe. For that reason, people might like the tangible link that they feel to the rest of the universe when they think of this - it’s amazing to think of how small we are in it, but also amazing to think of where “we” came from.
pgalvin··on UK government exempting itself from cyber law inspires little confidence
The front page of the BBC right now, at the very top, is a large photo of protests in Iran. The headline reports that hospitals are overwhelmed by the regime cracking down on protestors.

The article focuses on first-hand accounts from medics inside Iran, describing the crackdown and casualties. It also contains statements from the Iranian opposition, the UN, US and French presidents and British PM, all critical of Khamenei, with just two mentions of the regime’s official statements.

Also, I just switched to the BBC News TV broadcast. The Iran protests are the lead story: a special report with a focus on the protestors, showing videos shared by them.

pgalvin··on Fighting Fire with Fire: Scalable Oral Exams
University exams being marked by hand, by someone experienced enough to work outside a rigid marking scheme, has been the standard for hundreds of years and has proven scalable enough. If there are so many students that academics can’t keep up, there are likely too many students to maintain a high standard of education anyway.
pgalvin··on McDonald's is losing its low-income customers
OTOH, no company or item exists in a vacuum. If McDonald’s suppliers have increased prices, and their employees expect higher wages due to inflation, then McDonald’s must increase prices or eat the cost (unsustainable in the long-term). Does this only contribute to inflation? Yes. But so does every worker who wants higher wages - unfortunately everybody in the chain has such little influence on the wider economy that they must simply prioritise themselves.

This is an overly simplistic view, of course, not least because it presumes good faith, but that is really my point: the economy has too many moving parts to simply say “you’re to blame for inflation because you increased your prices”.

pgalvin··on Anthropic’s paper smells like bullshit
Anthropic does seem to have more ethical practices on that than most companies in this space, purchasing and scanning physical books rather than pirating them as Meta and OpenAI did. However, books are cheap, and I’m unsure of their wider practices.

pgalvin··on Report: Tim Cook could step down as Apple CEO 'as soon as next year'
That lecture is by a doctor who had widely discredited views on cancer, often cited as an example of quack, pseudoscientific claims on the topic.

His claims, specifically on cancer, were widely and roundly rejected by the scientific and medical community. This is not a controversial statement, either - his supporters proudly proclaim that his views are rejected by the vast majority of experts which, in my opinion, pretty much sums it up.

I highly recommend people avoid falling into this dangerous rabbit hole.

pgalvin··on FBI tries to unmask owner of archive.is
This is no longer true. They changed their policy to ignore robots.txt in 2017. I seem to recall that they still respected robots.txt later, though I can’t find any more information on it and may be misremembering. Currently, they do not.
pgalvin··on Bird photographer of the year gives a lesson in planning and patience
It looks like he is using an EOS R5, in the video he uploaded of him taking the photo. This is a mirrorless camera (very common nowadays) so the viewfinder is merely an LED screen with a live video.
pgalvin··on Health officials in the US are sounding the alarm over drug-resistant bacteria
Perhaps they meant to suggest that factory farms are overusing antibiotics, rather than the antibiotics remain in the meat we consume?

Anecdotally, I’ve heard plenty of concern (from the public) that the latter could breed resistant bacteria, but never even heard of your interpretation as a concern.

pgalvin··on Is 4chan the perfect Pirate Bay poster child to justify wider UK site-blocking?
For what it’s worth, despite the legal situation, it is virtually unanimously accepted by historians, journalists, academics, and the wider Irish and British public, that Gerry Adams was a member of the IRA. Nobody seriously disputes this.
pgalvin··on Thoughts on Daylight Computer
I may have misunderstood your comments on Kindles. How are they the worst tech product you use, if you also think they’re the best at their intended purpose? Do you mean that you still find e-ink technology lacking, but there is nothing better?

pgalvin··on Israel, Hamas reach ceasefire deal to end 15 months of war in Gaza
I think you might have misinterpreted the comment above you. I took it to mean that there are a set of circumstances unique to Gaza that cause greater conflict between it and Israel than between the West Bank and Israel, which is not sufficiently explained by generational trauma alone.
