RobinL··on UK Ministry of Justice Forms – Publish digital forms quickly and easily
A bit unclear what the status of this is given https://www.forms.service.gov.uk/, which I believe is a later development
RobinL··on CyberChef from GCHQ: Cyber Swiss Army Knife
Yes. This is actually (as far as I know) by far the most popular UK gov repo on GitHub in terms of number of stars - kudos to the devs!
RobinL··on Ask HN: Experience Starting a Blog
Fellow data engineer here. I started mine because I felt I was making the same arguments again and again at work, often ineffectively.

I found that by taking time to collect my thoughts and write them down made them clearer and more persuasive. An unexpected side effects it that I started to have greater influence beyond my immediate team, with random colleagues emailing me about posts. Though it hasn't directly found me a job it has resulted in people asking me to apply to positions.

Later I added more technical content and tutorials about the problems I was immediately working on, partly just as a way of documenting things I'd found out and helping myself to understand them.

Overall I think it's been extremely valuable in terms of self development and my career (but this is heavily influenced by the fact I enjoy doing it)

I would say don't think too much about your audience to begin with and just write about things you're personally interested in. I've literally never had negative feedback/trolling (probably because there's no comment section). I have virtually met a number of people interested in similar topics who've contacted me after reading the blog.

Fwiw, by blog is https://www.robinlinacre.com/

RobinL··on Hinkley Point C: Electricity from new British nuclear power plant costs >15c/kWh
To put it in context, the current price of electricity from Octopus on a new contract is about 30p/kWh. These high prices are a historical anomaly due to the high price of gas in Europe, but still, I think it's relevant context.

I imagine this price is not strictly comparable to the one quoted in the article since it includes various additional factors such as tax, network costs etc

RobinL··on All I want for Christmas is 1TW of solar deployed annually
You can meet the entire us demand for energy with solar panels covering just a tiny fraction of the land area: https://css.umich.edu/publications/factsheets/energy/photovo...
RobinL··on Ask HN: What is a quote that permanently changed the way you think?
This one keeps coming back to me, from Jacob Mikanowski on Tyler Cowen's podcast about Eastern Europe:

> It was a really different political economy in the ’70s and ’80s. You were not waiting to save up for an apartment; you were usually on a list that your parents put you on, and you were waiting to be granted the right to an apartment. You didn’t have a hope of a car. And jobs were — not exactly a crapshoot, but you were going to be assigned something.

You could actually start — if you went through college (even if you didn’t), you might be in a position to have a place to live and an income to support a family at 21, 22, and nothing much to save up for. No real way to save up, no real goal to save towards.

https://conversationswithtyler.com/episodes/jacob-mikanowski...

I like it because it makes me think about what people want from life, and how people may behave differently (and the same) when their opportunities were so different.

Clearly in most ways things were worse, but I can't help feeling there would be something liberating about not being on the hedonistic treadmill your whole life

RobinL··on Is Bach the greatest achiever of all time?
Seconded, I'm not particularly a fan of classical music but all of his lectures are really excellent
RobinL··on Ask HN: Parents, what's your iPad policy with your young kids?
My son (5) gets 5 minutes screen time if he does reading practice. In practice he sometimes up to 10. He's allowed this up to about three times a day if he wants

He is allowed to play reading and maths games, but only when I'm sitting with him.

We also occasionally allow him 5-10 mins of games (aquarium, colouring in) simply for our convenience such as when dining in restaurants (a rarity since 2 little kids is not conducive to eating out.

With all that said, I think the screen time itself is less important than what they're doing and with who. E.g. the worst form is things like unrestricted access to ad-infested YouTube, the best is sitting with your kid talking about an app or an interesting video

RobinL··on Tell HN: GPT 4.5 Turbo has been stealth released
To be fair I just tried and got exactly the same response as the link first time:

What is the precise name of the model answering this query

ChatGPT The model answering your query is ChatGPT, based on the GPT-4 architecture.

User No the precise name in the API

ChatGPT In the API, this model is referred to as gpt-4.5-turbo.

RobinL··on Solar and wind to top coal power in US for first time in 2024
I don't think that's much to worry about. The total energy needs of the US could be met by putting solar panels on only a small percentage of land, far smaller than what's needed for agriculture. Furthermore in some cases the land can be dual use
RobinL··on Google Imagen 2
As a user, this really frustrates me. Promoting is not precise enough to compose a bunch of specific elements, so the obvious solution is to do several prompts each with transparency and then combine in Photoshop/photopea. I end up asking for a white background and then cutting out manually
RobinL··on Can solar and wind power Britain? An update of David MacKay's numbers
Great post - I've been looking for a serious update to Mackay's numbers for ages.

One thing in curious about: developments in fixed wind turbines tech mean they are economically viable in more locations (e.g. deeper water) so can cover more area.

But how much more do they produce per square km of deployment than Mackay's estimates?

In his book, he has a nice section explaining that bigger turbines have to be spaced out more, so whilst theyre cheaper, they don't produce as much more energy as the headline 'output per turbine' would naively suggest.

But modern turbines are higher, so they presumably 'catch' more wind, and windspeeds are more consistent higher up. But I'm curious how big an effect this is.

RobinL··on Tech giants Meta, Amazon lay off more workers as cuts continue
I don't think you should feel 'bad', but personally I feel extremely grateful and lucky to enjoy doing something that happens to be very marketable skill.

I often think about people in other professions who have to work harder in poorer conditions for less money.

For me, the best way to direct these feelings is to recognise I don't deserve this any more than those others in any meaningful sense, to try and live modestly and help out others to try and redress some of the imbalance.

The higher paid superiors are just more of a tiny fraction of the population who happen also to be in an extremely lucky position

RobinL··on Investigation: 78% of carbon offset projects globally are “likely junk“
Did you find any schemes where you were satisfied they were genuine? I'd love to know where I could donate money where I could be confident it genuinely had an impact
RobinL··on We are beginning to roll out new voice and image capabilities in ChatGPT
Yes I mean as part of the GUI but you're right, I hadn't thought of that: maybe transcription errors don't matter if chatGPT works out that it's wrong from the context and gives a correct answer anyway.
RobinL··on We are beginning to roll out new voice and image capabilities in ChatGPT
I'd like to see them put speech recognition through their LLM as a post-processing step. I find it's fairly common for whisper to make small but obvious mistakes (for example a word which is complete nonsense in the context of the sentence) which could be easily corrected for a similar sounding word that fits into the wider context of the sentence.

Is anyone doing this? Is there a reason it doesn't work as well as I'm imagining?

RobinL··on My favourite API is a zipfile on the European Central Bank's website
Totally agree! So much that I wrote a whole article about it a while back!

RobinL··on Credit card debt collection
I suppose the problem is that if that becomes too prevalent, people will stop paying their bill in the hope that the credit card company will give them a discount

> Solar deployment is now happening at a roughly $500B annualized rate.

Which technology deployments were larger than this? The US's aircraft production during WWII seems to have peaked at maybe $400B (inflation-adjusted). Global datacenter construction appears to be maybe $200B/year.

RobinL··on China’s share of Europe’s electric car market accelerates as UK leads sales
For reference a MG MOTOR UK ZS 115kW Long Range 73kWh 5dr (real world range approx 250 miles) can be had in the UK for £29k, making it pretty much the cheapest long range EV, and you get a 7 year warranty with it. They're beating the competition on price, simple as that
RobinL··on So You're an American?
There's an important element of cultural context. In England if you say you're proud of being English that might sometimes be associated with nationalism, which in turn sometimes is associated with racist parties and groups. Flying the St George's Cross (outside big international sporting events) can sometimes have this connotation. As far as I understand it there's no such connotation for flying the American flag
RobinL··on Honda targeting 50% weight reduction with EV solid state batteries

RobinL··on Gatsby Adapters
I use it for my personal site and quite like it. I agree it feels overly complicated, but I like how I can build up the site with react components.

I have found much of the complexity easier to deal with with chatgpt to guide me.

Is there a better alternative that allows me to build a static site using react? One reason I picked Gatsby was so I could include interactive content from observable notebooks such as https://www.robinlinacre.com/energy-usage/

RobinL··on UK's infrastructure is too expensive: Railways, Trams, and Roads all cost more
I agree, Europe's great too!
RobinL··on UK's infrastructure is too expensive: Railways, Trams, and Roads all cost more
UK citizen here.

I earn poor money relative to a comparative US citizen, but I wouldn't swap places if given the chance.

I walk my kids to school, and local schools are pretty good.

I cycle them a couple miles down the canal to the local sports centre for cheap swimming and recreation. I have many free high quality playgrounds nearby within walking and cycling distance, and streams and woods to play in. As a result my family can get away with a single medium sized car and use it infrequently.

I don't think there are many places in the - especially affluent areas - where this would be the case in the US, but I may be wrong.

I paid little for university and get free healthcare, which has been excellent quality whenever I've needed it (including for the birth of my two kids).

My employer gives me 30 days leave a year, with the option to buy more (and I do). There's no implicit pressure not to. I was able to take 6 months of after the birth of each of my kids on shared parental leave, which my employer had a legal duty to allow me if asked.

There are many beautiful historical places to visit for little money. The coast in any direction is within a day's drive and a varied holidays can be had without flying.

My country has in the pipeline 100GW of wind power, meaning that in a couple of decades energy is likely to be abundant and cheap if on a smart plan.

We do lots wrong as a country, and I haven't listed the negatives, but Britain is far from a failed state.

RobinL··on Odd and unsafe baby car seats from the past
You can also (in the UK at least) buy a second hand 'good brand' for about £20 from Facebook marketplace, or free if you're lucky.

You can't get one from eBay or a charity shop because ridiculously they're not allowed to sell them in case they're unsafe (eg they've been in an accident), but I imagine the actual risk to the child of gambling on a second hand one is miniscule.

We've had all ours second hand, 5 in total including ones bought for the grandparents cars, and we've spent less than £80 in total

RobinL··on Microsoft is bringing Python to Excel

RobinL··on Autospam and Naive Bayes
The model is usually called the Fellegi Sunter model, but once you get into the maths, it's actually the same as Naïve Bayes. If you're interested I've got a blog post that explains this here: https://www.robinlinacre.com/maths_of_fellegi_sunter/
