My big issue with LLM code is not its access value. By all means use it! But let’s not pretend that it is a magic wand that replaces true expertise. Not much different from being a physicist vs being a layperson with access to LLM fo answer physics questions

I think access has its value but also access has it’s limitations. You can’t really write sophisticated parallel HPC code without having to deal with the sophistication that comes with it : sometimes it is just hard and you have to learn the tools.

well, the only thing they are spreading is drunken-ness! (seriously though, it's not going to help growth in anyway, but the argument that "it is terrible for <harm reduction reasons>" is just not watching the world closely enough. The worse harm comes from getting your brain cooked by the web.

I started coding with 6502 binary (yes I am old) and moved up that ladder, and C++ OOP was like the panacea. Then python hits and I have sad faces since then.

You see the jump from C++ to python is a terrible degradation of coding skills unfortunately.

As a teetotaller parent spending lots of weekends with zombie stare parents at soft play and playgrounds, a lot of things now make total sense.

In my fantasies late pubs will lead to afore mentioned late night food culture…

What I really wish though is the creation of a late night food culture. Midnight kebabs are just not cutting it for me

Yes not questioning that raising business costs then doing this is not going to grow so much. But any kind of getting people out of their houses and meet real people instead of getting their brains cooked on the web is a net plus imho.

Apparently “Fun is bad”. This moralising is so tiresome. And I don’t even like or go to pubs.

Ohio State astronomy is still waiting to see what happens with the federal funding landscape before deciding whether to proceed. With programs that are still TBD, I recommend waiting right now because *application fees do not get refunded if they decide to cancel after you have already paid*!!

Short explanation of the physics Nobel Prize 2025

In classical mechanics you can know where a particle is and its momentum at the same time. In Quantum mechanics you can't. All information is in the wavefunction. Even if a particle is trapped, part of the wavefunction..

No, it's not. It's all a lie. The blunt truth is across the 1991, 2001, 2011 and 2021 Census *every* ethnic group in the UK has become *less* geographically segregated and *all* groups, majority and minorities, are more likely to interact with people not like them.

the answer to the trolley problem is not to pick who to sacrifice, it’s to dismantle the system that led to an unsafe trolley crossing.

if any part of your morality strategy involves picking a group to let die on a hill, throw the entire strategy out. it’s wrong.

Woman 'arrested' over 'I oppose proscription of Palestine Action' sign A PROTESTER has claimed she was arrested for holding a sign saying “I do not support the proscription of Palestine Action”.

Yeh, you can't even disagree with the action of declaring Palestine Action a terrorist group. Pretty sure they will just try to arrest anyone with the words Action & Palestine in what they deem to be the wrong order at this point. Some politicians are really in need of swift replacement.

I know this is uncomfortable to admit, but there is a small area in England's second city where people are just not integrated with the rest of society. Many of them hold views that arguably go against British values.

Yes, we need to talk about the Tory conference in Manchester.

I feel sorry for the poor Met officer (who honestly is probably wishing the ground open up to swallow him up), and also salute the courage of the gentleman/terrorist* who is standing up for his beliefs.

Five UK universities tell staff they can’t afford pay rises Negotiations over whether to honour 1.4 per cent increase ongoing at several other institutions amid financial crunch

'Staff at some institutions will not get even get the small rise due to them because of a clause in the negotiations that allows for a delay for up to 11 months if a university is facing financial difficulties.' So far, Dundee, Kent, Brunel, Coventry, Swansea.

King’s admissions team working very hard to convince applicants of the value of Asian and Middle Eastern Studies and other arts and humanities degrees. Godspeed, may these words be heard by young people filling out their UCAS forms.

"If your supply chain uses AI coding, you should assume it’s dangerous trash put out by morons. If any of your upstream dependencies has a .cursor folder, you need to assume they’re not competent, and remove that dependency pronto."

I wonder how much of this narrow focus on electoral combat is due to the exponential increase in availability and use of polling data? I notice in other management contexts that leaning on “data tells us <narrowly defined checkbox goal>” can easily masks the lack of overarching principles for action

5 years ago, we made the strategic choice to transition our CPU based numerical relativity code GRChombo to the now GPU based GRTeclyn. It took a few years to design and develop (we called it “future proofing”) and we are proud of it.

What I didn’t think of 5 years ago, was to buy NVIDIA stocks.
