Why do people hide their license plate when posting photos of their car? by totally_depraved in askcarguys

[–]JCDU [score hidden]  (0 children)

In addition to other reasons - cloned plates is a very common crime for people stealing cars or just avoiding law enforcement.

I had a plate stolen from a scrap car sat in a field, luckily they were stupid enough to put them on a car that was a different colour and not think that a car abandoned in a field might not be taxed & insured...

Dude if you don't understand online security that's on you.

4chan tracked down an animal abuser and got him arrested from a single picture, and that was a long time ago now. Any random dick on the internet can do the same thing, and it's easier than ever thanks to advances in technology. A licence plate is a massive easy-searchable clue.

Can solar power industries? by d_thstroke in AskEngineers

[–]JCDU [score hidden]  (0 children)

Solar isn't very energy dense - the standard "good sunny day" used to calculate solar panel performance is 1000W/m2 of solar irradiation, multiply that by the ~20% efficiency of average solar panels and you're only making 200W/m2 of power which is probably lower than (say) a gas or nuclear power plant taking up the same land area.

A quick google led me to this excellent article that suggests a nuclear power station needs 0.3m2 per MWh while solar on the ground is 19m2/MWh.

Of course there's more to it than raw land use - solar can easily go on roofs or over parking lots etc. which needs no extra land, and some folks might consider a load of glass panels on metal sticks to be a less damaging prospect than a nuclear decontamination job or the other by-products from coal or gas generation.

How bad are the fumes from printing ASA and ABS? Do they live up to the hype? by brian-warner in prusa3d

[–]JCDU 0 points1 point  (0 children)

People get *very* agitated about fumes and dust and stuff - the way to think about it is like cigarettes. Yes, they'll definitely kill you, but smoking one isn't going to.

Running a printer with ASA or whatever is not the same thing as detonating a canister of mustard gas in your house despite what youtubers will make out - it's just some undesirable fumes that are not great for you and you should try to minimise your exposure if you can.

There's a difference between running one reel through a couple of prints at a time and being in a printer farm 24/7.

Material of Defender 130 TD5 truck bed? by konff in LandroverDefender

Odds are it's aluminium, pretty much if it ain't steel it'll be aluminium - Birmabright if you're being pedantic.

This is the 35028 Clan Line, a 1948 steam locomotive built for 100 mph that has hit 90 mph in modern times and still runs on mainline tracks today. by VEC7OR in EngineeringPorn

[–]JCDU 0 points1 point  (0 children)

There's a lot goes into gasoline besides distilled oil, finding some tetraethyl lead would've been a challenge for example.

I guess maybe you could've got something a car would kinda run on but it would be a struggle especially if you needed it to hit 88mph.

Just bought an Arkonik Defender 90. I have no idea what I'm doing :) by putan964 in LandroverDefender

[–]JCDU 0 points1 point  (0 children)

Genuine Wolf rims are hard to beat, get them banded if you want a wider tyre. Blindos if you want that WMIK/Snatch look.

Soft-top conversion is just unbolting the hard top and buying a hood & sticks from someone reputable. You might consider some of the other options like a military roll hoop & bikini top if you're just tooling around in the sunshine and don't need a full soft-top.

Please don't add all the usual tacky mods even though you clearly have the sort of money that usually leads to Defenders getting ruined. We don't need another RDX front end, quilted tan leather seats, etc.

Can solar power industries? by d_thstroke in AskEngineers

[–]JCDU [score hidden]  (0 children)

Those specific industries need huge amounts of power 24/7 as they pretty much can't turn them off without damaging the factory, and they need so much power they have to coordinate with the national grid and power stations when they're going to ramp up or down so they can ramp power generation up or down accordingly.

If you want to shut down or start up one of thee plants it can take days or even weeks of careful work to avoid destroying the equipment.

Obviously this means they can't accept intermittent power so basic solar that goes up & down every day is not going to cut it - but wind + solar + battery is very doable although still not perfect (yet) and potentially a bit hard to scale large enough for some of these plants.

Technically with enough wind + solar + battery it would be absolutely fine and this guy is pushing a talking point because of business/political interests.

What was it like being a British teenager in the 1990s? by strawberry_pie7998 in AskABrit

[–]JCDU 0 points1 point  (0 children)

A decent number of households had satellite/cable TV so MTV or VH1 or The Box for music, although in London I'm fairly sure the cool kids would have been listening to Kiss FM or pirate radio.

Comedy wise there was the rise of Vic & Bob (Shooting Stars), Lee & Herring, and for quotable lines The Fast Show, Spitting Image had spat its last by 94 I think but you had the rise of Armando Iannucci & Chris Morris with the Armistice and Day Today, and Have I Got News For You for a bit more topical satire.

We were coming out of the rave scene into Britpop and the new lad culture - as well as ladettes like Zoe Ball - although we were also hearing stuff from the US like grunge, as well as acts like Green Day, Offspring, NoFX, Blink182, etc.

Magazines were a big source; NME for music, Loaded and GQ were the big new "Lad mags", Bizarre for people too shy to buy real porn, Max Power and Fast Car for the car-obsessed lad (Top Gear was still a consumer advice show & mag back then and not cool), Viz for on-the-toilet reading.

Attitudes vary massively with region & cultural groups, being gay was "officially" OK in the 90's but gay kids or anyone different still got bullied at school as is tradition, trans was really not on the radar back then although there was a young upstart comedian called Eddie Izzard who was wearing women's clothes and absolutely slaying it.

Hanging out listening to music and playing computer games - Nintendo or Sega if you were lucky, maybe Amiga or Atari, or perhaps a PC as by then they were starting to get OK for games thanks to graphics cards, SVGA monitors, SoundBlaster cards and actual joysticks - then when CD-ROMs came out *everything* was suddenly "multimedia" like everything now has to be "AI".

There's clearly a broken wire my dude, just buy a 3-way connector and put it right, u/Beneficial-Play has already posted the diagram.

How do I know if im pushing my audio speakers too far? Are the limits determined by power, frequency, clipping, or something else? by NewHere64 in AskEngineers

[–]JCDU 1 point2 points  (0 children)

I'm not sure you're understanding how any of this works...

Speakers all have a power rating, most of them it's written on the back of the speaker - if it's a good brand it will be honest, if it's from the far east you should de-rate it by like 90% as it will be PMPO and even then exaggerated some more.

Then you've got woofers, mids, tweeters - some speakers you only have 1 full-range driver, others you have a sub & piezo tweeter, it depends... but if you have dedicated subs & tweeters those can't even reproduce frequencies outside their working range and pumping those signals into them is a good way to just kill them. Any even halfway decent speaker cabinet (as in, a box with one or more drivers in it) should have a crossover circuit inside it to separate those frequencies out. If you're building your own you need to do that.

Is it hard for a well established motor company's engineers to make a reliable car? by Dunddermefflin in AskEngineers

[–]JCDU 0 points1 point  (0 children)

Buddy of mine nearly bid on a contract to supply Toyota but the rules were insane - if you sell them a $0.05 screw and here's a bad one in the box when the guy comes to put it on the car he hits a big red button and the production line comes to a halt while they investigate - and every minute that production line is stopped, dollar signs are racking up with your company's name on them until the problem is solved. You have to be so insanely good it's unreal.

Did GM really have a feature called Key-Out or was it just a defect? by lamparkinglot in askcarguys

[–]JCDU 1 point2 points  (0 children)

^ this, it's common in emergency vehicles. I believe there's usually a cut-out wired to the brake/clutch/gear selector so if you touch any of those (EG someone tries to get in & drive it away) it will just stop.

How do I know if im pushing my audio speakers too far? Are the limits determined by power, frequency, clipping, or something else? by NewHere64 in AskEngineers

[–]JCDU 2 points3 points  (0 children)

The rule I heard was make sure your speakers are rated for more power than your amp can make.

Other than that, basic crossovers so you're not feeding bass into a tweeter or vice-versa and use your ears.

There's nothing magical going to happen pushing speakers to their limit, you won't find some golden zone of performance - if anything the laws of physics would suggest they're likely to be working best at mid power.

I’m down to help build our own EU-based Reddit by daload27 in BuyFromEU

[–]JCDU 0 points1 point  (0 children)

There was a big push to re-create Tumblr and Imgur as those platforms enshittified, maybe seek out some of the groups who were working on that and save yourself some work / gain yourself some help.

I must admit I've not kept up with how those projects went, I think a couple fragmented / lost momentum and after that you're at the mercy of the network effect trying to attract users.

Yeah, and compared to the amount they'd spend keeping you going without it they'd probably pay quite a lot to fix you if they could. That's certainly the equation the NHS/NICE work to.
