English is not a prescriptivist language. This is a common enough form, so it's fine.

TNT is good because not only will it release it's energy all at once, it's not super easy not insanely difficult to make it so so.

By the way, kerosene has been popular for ages, and was used in the Saturn 5 and the ill fated N1.

I mean given I'd maybe expect it to be marginally stable at LN2 temperatures, that doesn't imply it's particularly stable. More stable than expected is more like survived long enough when treated with extreme delicacy to take a few measurements.

And for rocket fuel you don't generally want something that will happily donate the entire fuel supply with the slightest provocation.

Really this sounds like it would make another fun article in the "things I won't work with" blog under the category of lunatics destroying lab equipment with hilariously unstable compounds consisting of far too much nitrogen.

Props to those lunatics for making it!

Can confirm they were idle for ages. Years in fact. And somewhat idle before that, it's not like I wear smart shoes often!

Yes, it is. The best I can describe it is that it is some combination of installed base, commonality of parts among model years and an insanely loyalty customer base. The Jeep Wrangler platform is supported by a huge quantity of third party vendors that cater to this market. You can buy COMPLETE BODIES for models that are 30, 40, 50 years old - for example.

OK, that explains it, well, half of it! Jeep don't IIRC have the best reputation for reliability, but if you can basically replace everything forever, and often with better parts that's a different ballgame.

I had never done anything like this, not being a mechanical type, so I learned A LOT!!!

High five! I genuinely mean that. I wasn't born knowing how to fix my bike, I had some help, then had a go, watched videos, learned and kept doing it until it worked. It's also deeply satisfying, saves money and ultimately saves time, or maybe reduces uncertainty which is arguable more important.

I snapped a gear cable recently. I stopped by my local bike store, picked up a replacement, and replaced it before setting off on my commute the next day. Honestly I think the repair took about as long as chinwagging with the talkative guy in the shop.

With all of that work completed, the thing drove better than new. I mean, it was incredible!!

That is a fun feeling I can share. Having the vehicle work better than new from your own work is deeply satisfying. You also get something customised to your tastes, something that wouldn't exist or be affordable otherwise. And unobtainable anyway because you wouldn't have known what to ask for even with a much larger budget.

It's an ecco pair. Super comfortable! This cobbler has already repeatedly resoled and reheeled several ecco boots I own. If I need another new pair at some point I shall look into those.

From what I remember, Musk didn't outright lie, but he was cunning with his wording and definitely helped the press to publish falsehoods which made Musk's system seem much more revolutionary than it really was. I think if you dig out posts from 8 years, you will probably find me ranting about Musk and how is real skill was being, well, a slick salesman.

"A while ago Australia installed what was at the time the worlds biggest battery.

But that's also completely wrong, or rather people blindly reporting Musk's bullshit without bothering to fact check. It was the largest lithium battery at the time, not the largest battery.

At the time the time the "world's largest 129 MWh" battery was installed in 2017, there was already a bigger one (300MWh) running in Japan. But Musk said so so the press blindly parroted that shit ad nauseum.

Anyhoo just sayin' though you are of course correct that battery response is fast, and certainly not seconds to minutes. And the OP is also wrong about flywheels being slow (250ms). Much like batteries they run at the speed of the control electronics.

And of course the other kind of flywheel (generators or synchronous condensers) offer power within a fraction of a cycle, based on the phase difference, so also have a very very fast response time, combined with a silly amount of instantaneous power, though not significant energy storage beyond timescales of a few seconds.

WHY? I notice that article just absolutely does not specify the reason why.

So CEOs can save money and get richer.

But also to pick apart what he said:

> "Every person should be using AI daily for as many things as they can. Like any new technology, it will feel awkward to start with, but every business person, every business leader, every government leader, and every bureaucrat should be using it

OK let's just get this out of the way first: Christ alive, what a twat.

I'm an engineer, always been on that path, starting as the nerdy kid who took stuff apart. I'm not a stranger to adopting new technology. I got into computing in the 80s when most homes didn't have one, and it felt natural and right not awkard. My life from childhood to career has been adopting new technologies. I hopped on board bluetooth low energy as soon as the first devkit came out (even then it was obvious much of the IoT garbage was overblown wank). Modern MOSFET RRIO opamps? Hell all of the modern chip industry! That shit is amazing. Sign me up! DVCS over CVS, despite being fundamentally more complex? Fuck yes. Linux over old unix? yep (also the fact I could get it and afford it did help there).

AI... well... I've tried it and I keep trying it. The problem isn't that it's awkward (I've dealt with loads of awkward stuff that's better), it's that it's just not as good as proponents claim. As an achievement in ML, it's amazing, and it can certainly do some stuff well. But it's utter bullshit that we should be using it all the time for everything. I often use it to avoid engaging my brain because re-prompting is easier than thinking, but I have definitely encountered many cases where actually thinking for 30 seconds would have given a better result quicker. But AI feels fast.

So he can fuck all the way off. I am not afraid of new tech. And certainly not afraid of awkward tech. It's that I use it and it is not anything like as good as these idiots are claiming.

It's a 2007 Jeep Wrangler, so it will be a long time before parts availability is an issue.

Is that specific to Jeep? I don't have much experience in this regard but I know other people for whom much less heavily driven vehicles aged out due to lack of parts. Might have been over 20 years though (and was a decade ago), but also might have been lack of a good mechanic.

Engine blew and took catalytic converters with it.

I think that's the point most people would tap out and get a replacement car.

On the other hand people's attitude to repair is strange IMO, to the point where repair people have sort of internalised it through dealing with customers.

I have a pair of barely worn smart yet comfortable shoes which I have for formal events which is now a less than yearly occurrence. I've had them a number of years, and I wasn't wearing them much pre-covid, then didn't touch them for about 4 years. Went to an event and towards the end the soles fell apart. Like, just disintegrated. They were made of some sort of urethane rubber foam and it had degraded and they just fell apart into chunks, leaving the internal structure exposed.

So, I took them to the local cobbler to ask about repair. He said it wouldn't be worth it, since it'd be over half the price of a new pair of shoes. I persisted because (a) it's cheaper, (b) I know the shoes fit, (c) I have to do zero work finding new shoes that fit, and also (d/e/f/...) I don't like waste, it keeps money in the local economy, keeps a very useful shop in business and so on. But even if you ignore the hippie shit and enlightened self interest, from a pure narrow self interest, it's still cheaper and less work for me.

But then again I've used them many times before and I know the money would be better spent there than on new shoes.

People have this attitude that they won't do the work.

I'm not a car guy and have never done car work, but I've never really had a car to work on. I do do other things myself though, and I find a lot of tasks easy. I do have some kind of affinity for working with tools, I enjoy it and I pick it up easily. And I've had people to teach me on the way. After many years of biking around, and fixing problems, I'm at the stage where I can swap out a frame in about 4 hours (well maybe less now, after that experience I bought a stand, finally, yes that was the wrong order), and things that people take it to the shop for (snapped cable), I can fix in less time than it takes to talk to the guy in the shop about it once you're there.

But that's after deades of practice.

With that said, there's a lot of learned and even performative helplessness with people that I don't like.

Or they add on emissions type stuff, which adds complexity, parts that will fail 15 ears down the road (like that rusted EVAP canister under the rear bumper).

I'm fine with it being illegal for you to dump noxious fumes into air I breathe.

Hole digging ain't skilled labour. Almost every job needs training, that doesn't make it skilled work.

The answer to your question is "yes".

When you start claiming that the people digging holes in the road are "artists", surely even you must start to question your line of thought. Nahhhhhh!!

I use Lenovo, myself. Not only do you get living, breathing humans, but they'll even send them somewhere of your choosing to swap out a broken motherboard. Apple don't do that because to Apple it's more important to screw over the tiny fraction of people who would upgrade the storage, or not pay full Apple prices than it is to offer good warranty service options.

No microsoft involved. Not only do they offer a supported Linux install, they simply don't care. Installing a new OS won't void the warranty and all their diagnostic tools run from bootable USB images making them OS agnostic.

Speaking of not voiding the warranty: they even provide a very detailed list of which parts are user replaceable within the warranty.

Linux treats me better than anything.

An artisan (from French: artisan, Italian: artigiano) is a skilled craft worker who makes or creates material objects partly or entirely by hand. These objects may be functional or strictly decorative, for example furniture, decorative art, sculpture, clothing, food items, household items, and tools and mechanisms such as the handmade clockwork movement of a watchmaker. Artisans practice a craft and may through experience and aptitude reach the expressive levels of an artist.

That deasciptionn from Wikipedia. I find it honestly quite funny that you describe the builders at one of the largest highways contractors in the UK as artisans. Could they through experience and aptitude rise to the level of pothole filling artists?

Beyond that I have no idea what you're blathering on about. You seem to be simultaneously engaged about how I don't think shovels are obsolete and how shovel proponent me is unaware of older tech like shovels.

Diggers have not made shovels obsolete, neither are shovels used exclusively by artisans.
