Just what we don't want if the US is putting weapons in orbit, an idea which is even more stupid than Trump's ballroom.
Kessler Syndrome is a theoretical situation in which space around Earth becomes so crowded that collisions between objects cause a cascade of debris, eventually making orbital space inaccessible. A ballistic weapon that could generate a cloud of space junk is therefore less than ideal

The photo shows a large plain wall with bright white in the top half (having a window showing a blue sky) and a bright yellow bottom half which has a hidden stairway sloping down from left to right. The head and shoulders of a man are seen in profile as he walks down the stairs.

Much more sensible than the amateurish way that the UK Brexit referendum was organised. Do it in stages, with explicit approval needed for an actual negotiated deal.
Crucially, the referendum will decide only whether the government of Iceland should restart accession negotiations with the EU; it is not a vote to determine whether the country should join the EU. That decision would need to be put to a second referendum, as well as being ratified by the 27 EU member states.

I've added Alt text to the screenshotted poem in the quoted post. Extracted with Google Lens & checked by eye.
The Bright Field

I have seen the sun break through 
to illuminate a small field 
for a while, and gone my way 
and forgotten it. But that was the pearl 
of great price, the one field that had 
the treasure in it. I realise now 
that I must give all that I have 
to possess it. Life is not hurrying

on to a receding future, nor hankering after 
an imagined past. It is the turning 
aside like Moses to the miracle 
of the lit bush, to a brightness 
that seemed as transitory as your youth 
once, but is the eternity that awaits you.

R.S. THOMAS

Important part:
We will also strengthen local accountability mechanisms to reflect the greater funding freedom for mayors: chief executives of mayoral strategic authorities will become Local Accounting Officers, accountable for the use of public money. There will be a stronger role for the Local Audit Office, and we will discuss with the National Audit Office how it can complement this.

Includes this interpretation of the Mahmood appointment, which sounds very plausible. Don't abandon hope yet.
The Mahmood re-appointment is obviously terrible. It is a big loud warning sign flashing above this project. But the most realistic interpretation is not that Burnham will pursue the ‘fuck-liberals’ agenda. That runs contrary to nearly everything we know about him. It is that he thinks Mahmood has become talismanic of Labour’s reliability on immigration to more socially conservative voters and must therefore be retained, but that her proposals should be softened and moderated.

This statement appears to be in denial about the actual situation in the US. "each generation has pushed us a little closer to its ideals" - so that's how you ended up with Trump? "celebrating the country we have" - the one with Trump as dictator-in-chief?

This is the key point, but it's not just the PLP that don't support the performative hostility, it's rafts of voters who've abandoned Labour because of this ridiculous stance from Starmer's government. Burnham has to put a stop to this nonsense.
“This is Labour’s reset moment when we can consign to the past some of the appalling language used by politicians to describe refugees: ‘invaders’, ‘an island of strangers’, ‘tearing our country apart’. We can’t reset by bringing with us policies that many in the PLP do not support"

Take the reforms to indefinite leave to remain. These plans make it almost impossible to integrate immigrants into the community. They exclude people who are here legally, in many cases for well over a decade. 

Ignore the moral element. Who does that actually help? What problem does it solve? Which issue is it supposed to address? None. But then that was not the function. The function was to appeal to Reform voters. Decades from now, someone will be suffering as a result of these changes and no-one will really remember why they were even introduced or what the purpose was.

Boosting this important point from Stephen's very good piece, with alt text added.
There is a reasonable debate to be had about how suspects are treated. But we should be clear that the issue here wasn't that the Hampshire police decided that an accusation of racism was more serious than a stabbing. It was that, faced with two people giving a false account of what had happened and one person telling the truth, they sided with two over one. As a result they treated the victim as a suspect, and in England, being treated as a suspect by the police meant he was treated in ways that made his last moments worse. Whatever we think should be done differently has to start by grappling with that truth.

Extract from article. Text in ALT.
"OpenAI used a new reasoning model (not yet released) to help identify a counterexample that disproved a conjecture from discrete geometry first proposed by Paul Erdos 80 years ago. The model was tuned for so-called chain-of-thought reasoning where the model endlessly “thinks out loud” about whatever it is trying to solve, an approach that lets you approximate something like memory and dynamic computation using LLMs, which are otherwise static and feed-forward. Professional mathematicians identified the counterexample from within a long transcript of the model’s reasoning, and then extracted the key parts and rewrote it as a more succinct proof in a more standard style."

Very good, detailed piece about how UK governments have failed to be honest with voters about the need for immigration. Text in ALT.
"This is the migration doom loop. The government responds to political pressure by promising to reduce numbers. The easiest reductions come from routes that are economically useful and administratively controllable: students, skilled workers, dependants, care workers. The fiscal and labour market costs then show up elsewhere, in weaker public services, lower tax revenues and more pressure on universities and care"

Stark example of FPTP distortion in recent local elections, from this article
"And in Sutton, the results are stark. The Liberal Democrats have taken almost all the seats on the Council with a minority share of the vote.

[pie chart showing Lib Dems got almost all the seats in Sutton]

These are very different political stories, but they point to the same problem: First Past the Post distorts election results no matter which party benefits. Ultimately, the voting system is just failing to deliver for the voters."

Interesting section "Critical reception" in his Wikipedia page
His work has been more negatively received in academic circles, with Christopher Robert Hallpike stating in a 2020 review of Sapiens that "one has often had to point out how surprisingly little he seems to have read on quite a number of essential topics. It would be fair to say that whenever his facts are broadly correct they are not new, and whenever he tries to strike out on his own he often gets things wrong, sometimes seriously." Hallpike further states that "we should not judge Sapiens as a serious contribution to knowledge but as 'infotainment', a publishing event to titillate its readers by a wild intellectual ride across the landscape of history, dotted with sensational displays of speculation, and ending with blood-curdling predictions about human destiny. By these criteria, it is a most successful book."

Worth reading for how the system of *preferential voting* in Australia means that tactical voting & guesswork become unnecessary.
The winning candidate in a seat must secure a majority of the votes. Initially you count the first preference votes - the people who put that candidate first. Then you start redistributing votes for second preferences - people’s second best option - until a candidate gets over 50% support, at which point they’re declared the winner.

"Trump's Clausewitzian War" Very good analysis of Trump's aims in pursuing war with Iran.
Clausewitz’s point was that war should not be an end in itself, but a means to achieving some political aim. It may seem that Trump’s war, with its constantly shifting, chaotic objectives, is not very Clausewitzian. Trump’s wider political aims as President. These are: self-enrichment, the extension of his own personal power, to be constantly the centre of attention and to be able to humiliate and dominate his foes. There is no policy agenda, no ideological lodestar, no coherence or plan. Trump’s presidency is delivering his political aims successfully: he’s making a lot of money, he is the centre of global attention in a way that no previous president has ever been and he has destroyed the checks and balances of the US system. The fact that it seems chaotic and unpredictable doesn’t matter to him. Indeed it may be part of the point.

Alt text part 2. Apologies in advance for any Google Lens errors, BTW!
Falsehood is very powerful online (for example, through deepfakes and, in future, individually

tailored Al-driven communications).

Online accountability or responsibility is weaker than offline because of anonymity or

pseudonymity.

Increasing amounts of online are synthetic (generated by Al in one way or another). For some, generative Al will have an adverse impact on freedom of expression, so that more content leads to less speech.

The practicalities of removing user-generated content (digital takedown) are different from the implications of gagging live speech (arrest) or destroying books (pulping) in the physical world.

Eric Heinze of Queen Mary University has proposed that one cannot necessarily approach live speech in the same way as online speech. Given the factors listed above, I believe he is justified in querying whether classical free speech norms drawn from JS Mill should apply to online communications.

A more nuanced understanding of the applicable principles would allow a better standard of debate on online regulation and is directly relevant to weighting of freedom of expression required by the Act. Regrettably, there is little current academic exploration of this topic which is characterised by broad statements of undifferentiated principle.

Used Google Lens to extract text. It's more than 2000 characters, so it needs more than one post Alt text part 1
As is often the case, commercial self-interest is clear about its objectives (maximum engagement, minimum intervention) but civil society is conflicted, especially concerning the issue of censorship. As I have written elsewhere, the traditional approach of identifying fundamental human rights which may or may not be outweighed by the counterterrorism interest is complicated by (a) the unsuitability of the human rights framework in the online space and (b) the difficulty of understanding trade-offs between restrictions on free expression and the capacity of the internet in its current form.

This is even before one considers the implications, whether moral or practical, of free speech standards under the United State of America's First Amendment. Naïve assimilation of online content with offline expression ignores some fundamentals:

Evidence strongly indicates that, online, the remedy for bad speech online is not more online: the great Justice Brandeis was writing for a pre-online age. The online trend, experience now shows, is to polarisation not synthesis and understanding.

The online domain provides a platform for ordinary users to communicate their content to

millions which they would not have in the real world: it combines both "freedom of speech" with unprecedented "freedom of reach". Criticisms of broadcast regulation (for example, the 9pm watershed) is typically much more muted than of online regulation, even though many online platforms are broadcast facilities (e.g. YouTube).

Moreover the 'reach' of online speech is often determined by the platforms (algorithmically) not the user. As a casual user, if I post something on Instagram, I have no way of knowing how many people will view or interact with it. Whether my post has 'reach' actually depends on the platform's assessment of whether it will keep people engaged in the commercial interests of the platform - this process could be described as 'free speech' plus 'commercial reach'

Scathing piece, well worth reading
And this takes us to an important truth. It can be reductive to judge someone as stupid, thick or moronic. But it can also be true. It is clear that the overriding feature of Trump is his stupidity. Yes, he’s a sociopath, a child rapist, corrupt, vain, cruel and superficial. But most importantly, he’s an idiot. He doesn’t read, he doesn’t listen to people that know things, he doesn’t understand fairly simple concepts. An A-level politics student would be able to tell you that a war with Iran risks attacks on the GCC countries and a closure of the Straits of Hormuz. This is so widely talked about it would be almost impossible not to know. (It is just possible, if you are a moron who can’t listen.) Believing that a population will “rise up” with no weapons or structures against a bloodthirsty regime that killed tens of thousands of them only a few weeks ago takes a special kind of stupidity. Believing that you obliterated a nuclear programme a year ago, but also that it is now only days away from being able to produce a nuclear weapon requires a deep moronism, a level of cognitive confusion that is barely comprehensible.
