ljf··on Pentagon spending on drones jumps from $225M to $55B in one year
The rough cost to provide free breakfast and lunch to all students in the US is $30b - so as the go says, less than $55b.

It was sad when I checked some time ago how many ancient Japanese companies have closed in tbe last 50 years.

ljf··on If America's so rich, how'd it get so sad?
Look at the US median and consider again how many times that figure your own salary is.

And then ask your if that person on the median salary has a lot of disposable income?

They might be richer than someone in a poorer country, but the median in the USA, is not rich _in_ the USA.

ljf··on The AI School Bus Camera Company Blanketing America in Tickets
How do the cameras cause the crash, and not the lights themselves? Is it that the flashes of the camera causes people to brake suddenly, or the very presence of the camera causes some people to brake at the lights and others not to?

I find it interesting, as in the UK we don't have loads of red light cameras (though we do have them) but people driving through red lights is a rarity - even when there is no-one around and at night, the vast majority of people will obey a red light.

What I like about the automation of rules is that it takes away targeted enforcement and the opportunity for leniency to be offered only to certain groups.

The UK model for speed cameras is that they can (generally) only be placed in areas that have shown to have a higher than average number of accidents on the stretch of road, caused by speeding. So at least (in theory) they are focused on reducing accidents and not raising money.

Sadly I can't find any pics of the basic table we made, but that was actually an easy thing to make once I thought it through.

I basically got a 2 sheets of MDF to the size I wanted (roughly the size of a baking tray for the oven, as I had to heat the plastic in my home oven) then drilled a hole every couple of cm in one of them, then made them into a shallow box - sealing all the places the wood connected with bathroom sealant on the inside and duct tape on the outside. I made a hole in one of the 'side' pieces that would fit my vacuum cleaner hose, and then added more duct tape to seal.

Then I made two wooden frames as big as the largest baking tray for my oven, then cut some heatable plastic to size, and clamped them in the two frames and put them in the oven.

This part had loads of trial and error - ie how long the plastic needed heating, how long to run the vacuum cleaner, how to make sure the plastic didn't end up behind the thing you were forming, how to make sure the think you were forming didn't deform while under pressure.

Email in bio if you want pics or more info.

Very happy with the results - and learnt so much making it - i.e. building my own vac forming table to make the visor.

Loads of sanding and spray painting, in-all I think it took me about 70 hours, but we wore the helmets loads for festivals and parties.

I no longer have the file sadly, but got it from a paper craft forum - where people posted them. Happy to share pics if of interest.

Years ago I made a papercraft Daft Punk helmet, using standard printer paper, but glued it with super glue, and then treated it with the 'resin' from a home fibre glassing kit, to make it solid and ready for full fibre glassing (obviously not needed in this instance!)
ljf··on Škoda DuoBell: A bicycle bell that penetrates noise-cancelling headphones
Same reason I listen to music or podcasts in the car.

I am very lucky to live in a city/country where risks of theft from my person is low - when I lived for 20 years in London I never once felt unsafe listening to music.

The closest was two young men got very close to me on the tube, when I was playing on my brand new Hong Kong imported PSP - but I just took my headphones off. I think they were just interested as most people hadn't seem one in the flesh yet.

I can't say I know of anyone personally who suffered theft or accident caused by them listening to music on headphones.

When I cycled a lot, I had a small speaker strapped to my handlebars rather than wearing headphones, as I liked being able to hear cars around me - but when I was younger I regularly cycled in headphones, and was still able to hear enough of the road around me to not feel that I was missing anything.

Remember, we don't make drivers drive around with no music and their windows open, so that they are better able to hear cyclists...

ljf··on What life looks like on the most remote inhabited island
Dogs are pretty terrible for nesting birds, especially ground nesting ones. Even on a leash they can cause birds to leave their nests.

Similar for other small animals;

ljf··on The FAA’s flight restriction for drones is an attempt to criminalize filming ICE
There is lot of investment going in to fanning those flames - just look at the way the edges of this are discussed in the Epstein files.

Here in the UK, it is amazing to follow just how much money has been pumped into the various 'right of the Conservatives' parties for the last 15 years, while it might seem like a grass roots movement, the majority of the cash has been coming from those with vast wealth inside and outside the UK.

And inversely, if you break the law, and they 'like' you - then you are freed or never even charged in the first place.

ljf··on Digitizing photos from the 1998 Game Boy Camera
These look brilliant and remind me of the pictures from my Casio watch camera: https://www.casio.com/intl/watches/50th/Heritage/2000s/

I really need to dig that out, from memory the software only worked with Win98 or ME - but I guess there must be a way of getting it running elsewhere (or getting my ME laptop running).

ljf··on The road to electric in charts and data
I do get this view and in many ways I agree - for me a car in an investment in flexibility.

I could hire a car/van as an when I need one, and send my kids to school by taxi and do my local shopping by bike (which I already do other than the 'big' shop that my wife does).

But investing £3k 10 years ago on a 10 year old car (now 20 years old) has proven a great investment. In a bad year it has cost £500 pa in maintenance, but in an average year I pay more in VED(tax) than I do on a service and mot.

I could have bought £3k of ftse 100 stock and have used the dividends and growth for transport, but I think that has turned out better for me. But I'll be honest, I've not done all the maths, but I don't think investing £3k would cover my costs and I would have eaten into the principle long ago. At best I have a £250 (scrap value) asset now, but realistically if I continue to spend £200-500 a year on looking after my investment, I'll get flexible transport.

ljf··on The road to electric in charts and data
I saw a Nissan Note ev around here for £600 - the battery is good for around 24 miles - which exceeds what I'd do in a day on school run, gym run and shopping.

I would need to pay for a home charging point, but that would be a long term investment.

For me that Note would likely do me another 4 years of easy and cheap driving. An ice car of the same price would have more to go wrong and I'd be lucky to get 2 years driving from it. We are getting to the usable 2nd hand market already, and it is only going to get better.

ljf··on Enhancing gut-brain communication reversed cognitive decline in aging mice
No 2 is a fascinating study! My mother was 'taking' (eating) large amounts of raw chilli as she found it a very efficient cure for her rheumatoid arthritis - she had brilliantly reduced joint pain. BUT after a few years it caused painful and disfiguring rosacea.

She stopped the chilli and moved to acupuncture for the arthritis, which worked pretty much as well, but not something she can do herself at home for 'free'.

Since she has v low BML, I'm now pleased to see she stopped eating too much chilli!

ljf··on Ireland shuts last coal plant, becomes 15th coal-free country in Europe (2025)
Which to we ignore for coal? Cost to build a new plant? Cost to run? The decommissioning costs? (Yes we ignore the externalities, and no I don't think we should burn coal. My point is Nuclear has yet to pay its way anywhere in the world, without heavy heavy govt support - far exceeding that given to renewables)

Some figures on running costs: Coal costs about £62 per MWh - (£31 for the coal and £31 for the CO2 premium we already charge the energy producers).

As a fossil fuel comparison, Gas costs about £114 per MWh.

Nuclear - Hinkley C will cost about £128 per MWh - but likely to be even higher when it comes online. And we will be on the hook for this price as long as it runs, no matter how cheap renewables are.
