We ended up insulating it with sand, which kind of works.

Our solder pot died, and we needed one before Monday.... Luckily I had a cartridge heater in a drawer, and we built a new one.

There is a dominance of people who used to live in London and now live around the edge of London and commute into London, or have a fancy flat in a posh area. From a long way from London, this looks like London, but I can see how it wouldn't feel that way if you live in London.

The thing that gets me is how fast they recruited so many goons doing it. Were they having a normal life and suddenly thought, oh I could go and bully foreigners for a job?

Plus the jobs hardest to automate are probably the ones that involve a combination of thinking and practical things. Plus relying on China to make all our stuff is looking a less good bet...

I think there is an over emphasis on university courses at the cost of other forms of education, especially technical & continuing education. You are going to take in information better if it is spread over more time and less intensely, especially if it is relevant to what you are doing.

Be careful, any herb that actually has an effect is a drug, with an unknown dose, so you can do plenty of damage, depending on the herb.

My dad was a manual labourer, cutting lawns, and we had very little money, but we certainly weren't 'working class' in that sense, as my parents weren't working class in the 60s and 70s.

Yeah, it is all broken, as working class can be used to refer to a cultural group that were probably working class in the 60s or 70s, and haven't been make to think about society much since then.

It is also complicated by being 'working class' being fashionable in the 80s and 90s.

I assumed this was something more sinister as the photo looks exactly like every photo of a police station you see in the papers.

Yeah the difficult bit is working out what you should be throwing away

It is complicated by the way that Hamas did something awful so supporting Israel seems kind of reasonable until Israel did far worse things back. So the timing is very important on this.

12.08.2025 15:54 β€” πŸ‘ 0    πŸ” 0    πŸ’¬ 1    πŸ“Œ 0

What I can find is that this is around surveillance, to find hostages. If anything getting the hostages out sooner would have been better for the Gazans as it would have been harder for the Israeli government to justify continued attacks. It certainly isn't open and shut.

I am not against your aims in this, just your espoused methods, which I think are counterproductive because they are very easy to paint as being anti UK rather than anti a particular policy.

12.08.2025 08:57 β€” πŸ‘ 0    πŸ” 0    πŸ’¬ 1    πŸ“Œ 0

Yes, but then do something against the government, throw paint at Whitehall, tie yourself to big Ben, etc. the problem with attacking a military which has nothing to do with the Gaza horrificness is that you are attacking a national asset whose job is to protect the nation.

12.08.2025 08:55 β€” πŸ‘ 1    πŸ” 0    πŸ’¬ 1    πŸ“Œ 0

Yes, but throwing paint at aircraft is unlikely to make a difference to this.
Though my guess is that they are too scared of Trump, which is not surprising since Brexit, and our screwed economy.

The first of these is not really in the power of the British government. At the moment the cynical answer is probably to hand a few million to Trump in a brown paper bag, with the offer of more to come.
The fascism thing is deeper and probably needs, centre governments to transfer some wealth.

He is definitely encouraging extremists of all colours in an attempt to destabilise the west. I am certainly not saying he was planning the attack, but but it wouldn't surprise me if there was a significant amount of Russian propaganda in their feeds.

To achieve what?

11.08.2025 14:18 β€” πŸ‘ 0    πŸ” 0    πŸ’¬ 1    πŸ“Œ 0

But there would be no cost to the people doing it, which madness it easier.
It is entirely possible that this stunt was in some way encouraged by Putin as it is in his interests currently.

Yes, and they did many horrible things, war crimes, and many enabled dictators to take power. Occasionally they were useful for society. There are tonnes when it is necessary, but the UK is approximately a democracy and this kind of direct action is pretty much counter productive at the moment.

11.08.2025 08:35 β€” πŸ‘ 0    πŸ” 0    πŸ’¬ 1    πŸ“Œ 0

But how can you have a military in that case? Putin can just pay someone to destroy all our aircraft, tanks and warships as a political statement and we will be helpless.
Militaries can be used for bad things, but not having one is bad too.

11.08.2025 08:30 β€” πŸ‘ 0    πŸ” 0    πŸ’¬ 0    πŸ“Œ 1

If you damage expensive military hardware for a stunt you should definitely be prosecuted, but for something like criminal damage, or explicitly damaging the military, but not terrorism, and it isn't a proscribing groups issue.

Fairly straight forward but it could be applied to a lot of situations.

Women do have a slightly different career path on average, some of this is societal, some biological, probably most a combination of the two.
Though the fault lies with someone not noticing this and failing to plan for it.
Did the article writer have a better grip of this than the headline writer?

Does this mean that anteaters are unusually vulnerable to extinction, opening up the niche again? I guess dependence on one food would contribute.

Normal distributions and climate change exhibit

It was a pain to build because granular materials are hard, but here is our exhibit on why normal distributions mean a small change in temperature might have a big effect on the probability of extreme events.

Is it the classism, and or a lack of interviewers, let alone good interviewers? At which point TED is about the dream, not the possible.
