The cost has to be that high, considering the annual market for hydraulic underwater chainsaws can not be more than a few hundred at best. Considering the environment these are expected to work in means the R&D costs are considerably higher than your bog standard chainsaw, with much few units to spread that cost over.

That's the weird thing about software development, it can be done on a small budget. But large companies will find ways to spend money, i.e. by using loads of CI servers on AWS.

Infinite scalable CI servers are great for developer productivity - as long as they are easy to use

Apple has the biggest cash reserve of any company in the world.

Xcode is most certainly not free, at the minimum you need an apple computer. So you must pay apple to use it.

If it sucks, it's not because a lack of money, it's because Apple doesn't care.

Amazing, I actually saw one of these today at a flea market. I noticed it was hydraulic powered but didn't suspect it was for use under water.

> I noticed it was hydraulic powered but didn't suspect it was for use under water I suspect a gasoline-powered chainsaw wouldn't work underwater... which made me wonder if maybe that does exist because you could feed it O2 from a supply tank just like the fuel, maybe even from the diver's own air tank? Now I want to know how bouyant battery-packs are and if an impractically-heavy battery-powered chainsaw work well u…

If nothing else, you'd have a hell of a time insulating the high voltage parts of the ignition system from all of the rest of the metal bits.

I've been here 13 years and am not aware of this pattern. Also, gently, note: > Not singling out Apple, I’m sure all are comparably bad, it’s just what I happen to use :) The Xcode thing is often an in-joke with iOS developers.

> I've been here 13 years and am not aware of this pattern. I’ve been here 11 years and see this all the time. This, however, is not an instance of it.

I'm only aware of the opposite pattern

If you can push the fuel and air in at ambient pressure, it shouldn't matter much right? Because the 'neutral' point of the cilinder pressure would be just as high as the pressure of the exhaust. You'd probably lose some efficiency because the difference between peak pressure and neutral pressure in thr cylinder feels like it would be smaller. Perhaps not, because you could fit much more fuel and air in the cylinder…

Most of your engine's power will be spent pushing the exhaust into the water.

I believe he is insinuating a "two hose" approach

That chainsaw is a yearly subscription? I'd rather pay once for a chainsaw.
