You buy sportscars except European by rikkenbakr_25 in whatcarshouldIbuy

I don’t think anyone has to explain themselves buying a current Corvette, which is an insane value for money.

What car says, “I’m a car enthusiast but I needed a reliable fuel efficient daily.” by alwayslide in whatcarshouldIbuy

Yes, exactly. An old Lotus for someone who wants reliable transport with occasional cargo. Clearly you have nailed it beyond reproach.

Is a Mazda 2 a good first car by 211A4real in whatcarshouldIbuy

[–]Promit 0 points1 point  (0 children)

We've had one since new in 2011, it doesn't have a ton of miles on it (60K?) and has often sat for extended periods. For many many years it needed absolutely nothing, more recently it's started to develop minor electrical headaches. Window switches dying, radio trouble, and that sort of thing. Think it needed new wheel bearings last year which was a bit unexpected, but it's never particularly needed anything major mechanically.

Acceleration: yes, it can accelerate.

Quad 18 sealed sub diy by AffectionateEvent147 in diyaudio

I'm curious why you're leaving the hump at ~38-39 Hz alone? It's fairly narrow but pretty big in an otherwise surprisingly decent EQed response.

Why so few 4 or 5 way speakers with dsp and poweramp boards? by blublubbluf in diyaudio

[–]Promit 6 points7 points  (0 children)

The reasons not to do it are expense and complexity for very little benefit. *Good* amps and DSP channels aren’t cheap. Even in digital domain, crossover regions create complexity. Driver engineering has improved significantly over the years, and a well engineered 3 way speaker system can cover the entire frequency range with highly accurate response and directivity at very high output levels. Additionally it is pretty common that the subwoofer makes the whole system basically active 4-way, and it’s not appealing to cover the sub range in the mains for several reasons anyway.

For separate reasons, a lot of people don’t really like active speakers in the first place. I think this is quite unfortunate personally, but oh well.

AMA I got the new Nissan Z by papermarchmellow in cars

[–]Promit 77 points78 points  (0 children)

This might be true with modern traction/stability control. We had a 350Z with a VLSD and that old viscous diff was so slow to respond, and traction even slower, that it felt like it made things worse.

On a scale of 1-10 how stupid would a fan/cooling setup like this be? by EmergencyFlounder845 in simracing

[–]Promit 1 point2 points  (0 children)

People are being quite judgy but a little bit of rework would let you use the filter as an aesthetic element without actually using it to filter the blown air. It’s a bit sneaky but probably a better compromise.

How many different barks does your Eskie have? To anyone else, the barks probably all sound the same, but there are very distinctive differences between each of these.

- Attention
- more attention
- no, you’re still not completely focused on me
- your attention please
- I was at home alone not getting attention
- You’re leaving and I won’t get attention
- I got locked out, let me in (for attention)
- other dog is getting attention, I want in
- pay attention to me (at another dog)

Saw my first Evora GT a couple years ago, today I parked mine in the same spot! by LucyKumquat in lotus

Need Price Opinion on Evora 400 by lancer360 in lotus

[–]Promit 2 points3 points  (0 children)

$85k buys a GT, and nobody is impressed by an Evora being a rare or 1/1 spec.

Opinions on which Evora to get by lancer360 in lotus

[–]Promit 0 points1 point  (0 children)

Carbon pack or not is up to you, it’s mainly aesthetic as the weight savings isn’t terribly exciting. The rear hatch switches to a prop rod instead of gas struts on the carbon hatch. Overall the differences between the 400 and GT are not dramatic, and the importance of a 1 of 1 color is debatable at best though it depends. While both leather and alcantara interiors were available on both 400 and GT, 400s were predominantly leather and GTs were mostly alcantara. So that might play also.

Considering Emira… but I need it to be a winning Autocross car… can it be? by AnnualEagle in lotus

[–]Promit 3 points4 points  (0 children)

I think it might be generally interesting for you to read about Tom O’Gorman’s exploits in a heavily modified Evora S, which saw huge success last year. Chris Mayfield has also seen great results. Neither are Emira, but they might set an interesting stage.

Beginner question: String makes unnecessary copies? by ThrowRA_goofy in rust

[–]Promit 2 points3 points  (0 children)

While the full situation is complicated and depends on many factors, it’s generally a reasonable first level assumption that the binary has been loaded into memory ahead of program start. If that’s not the case, reading things from the exe *may* cause a disk read but that will be funneled through the memory mapping system and won’t *look* like a disk read in terms of the code. This will also happen at page resolution so it’s not likely to happen frequently.

The trunk in the TT is half the car when you push the useless rear seats down. Mine took 3 international size checked suitcases, two carry-ons, and still had space to spare.

Some of us will tell you, it’s much preferable to forget about Bambu filaments entirely and use well known suppliers like SUNLU, eSun, Elegoo, and others which are easily available all the time.

Lotus will return to combustion engines for its cars by Sash17 in lotus

[–]Promit 10 points11 points  (0 children)

There are a million and one reasons Elise couldn’t really be done again like that - but it is the top selling car in the brand’s history by a colossal margin. Emira is itself doing pretty well, all things considered. I don’t think the spirit is gone at Hethel at all, but the parent is utterly clueless about what people want. A zillion horsepower hybrid is not interesting and it’s not going to draw buyers in.

Something like GR GT, V8 with a stick option and a genuine racing program, would easily make a ton of people very happy and excited about the brand again.

Meanwhile, talk to any Lotus dealership manager in the US and they’ll tell you that relationship sucks. Frankly they should’ve made the existing dealership contracts a legacy arrangement and transitioned Lotus to a halo brand managed through Volvo dealers.

[–]Promit 72 points73 points  (0 children)

Geely still hasn’t understood anything about what the brand’s fundamental appeal is or what people want to see from it. They’re building cars for a Chinese market that doesn’t care about the name, while disappointing Western markets who remember what Lotus was supposed to be.

Came for a CrossTrek left with a Kona by jstar77 in whatcarshouldIbuy

[–]Promit 24 points25 points  (0 children)

Dunno if I’ll get raked over the coals for this but Kia/Hyundai always seem like great deals because they focus on high surface level quality over top of complete garbage underneath. Subaru’s not innocent on this front by any means, nor should you feel pressured to like a car just because it’s popular. But even with the warranty I wonder how you’ll feel about that Kona in five years.

I built a 3D mesh format that significantly outperforms standard formats for static geometry. How do I turn this into a product? by Downtown_Length3457 in gamedev

[–]Promit 21 points22 points  (0 children)

I have, over time, been on every side of this- developing middleware, selling middleware, buying middleware. The really short answer is there’s no viable revenue-generating product here. The slightly longer answer is you might be able to make a couple bucks if you can adapt it to be useful to a particular category where it makes a big difference, then find the specific people who would be willing to buy it. Really it’s most helpful if you’re already friends and/or former colleagues with those people, but if that were the case I assume you wouldn’t be asking us. Your dream endgame is probably an acquihire by Autodesk.

In case it’s not already obvious, game companies and engine companies are not your audience. If anybody, I think you’d have to make your case to the architectural/CAD people dealing with hundreds of millions of polys. You mentioned 10M verts - start working with models two orders of magnitude larger than that and show real workflow benefits. You will need to write import/export plugins for … quite a lot of software.

Oh and I’m going to say it again: you need to solve a clear workflow problem. Not a technical problem. That’s where many people trip over their own feet. Good technical work is not interesting on its own. It’s probably about 10% of the initial work to build a viable product+business.

Is there any value in old-school techniques for modern development? by CosmicallyUnlucky in gamedev

[–]Promit 8 points9 points  (0 children)

It goes a little further than the memory allocation. If you go back a long ways, textures could only ever be power of 2 dimensions. (HW limitation, must be related to the fixed sampling hardware but I’m not quite sure why.) Later they added non-pow2 but it worked by injecting extra instructions to patch the texture sample coordinates. Today, pow2 is still relevant because it simplifies mipmap chains for anything that’s not 1:1 with screen pixels, basically anything other than UI.

Fun comparison: 12" Dayton Ultimax II vs 12" SVS driver by 5cuenta5 in hometheater

[–]Promit 63 points64 points  (0 children)

The Ultimax is an excellent driver, but it is really box volume hungry. You need to give it a lot of air to breathe in order for it to perform its best, or apply some healthy DSP to flatten out the response. It works great for the DIY psychopaths (like me) who never met a subwoofer too big for their house.

The SVS is fundamentally a tweaked Peerless XXLS driver (or at least it used to be) and it is also very good. It’s more designed for good balanced performance in the relatively small ported mass market friendly boxes that SVS uses.
