The fact that the survival rate of startups hasn't improved doesn't show that our knowledge hasn't improved. Startups are competitive, with only 1 or 2 VC-scale winners per market. So, the claim is like "race car technology hasn't gotten better, because there's still only one winner per race."
Racing competition is flattened through regulation(oversimplified). All drivers have the same car. Drivers skill and fearlessness is the deciding factor.
I came here to basically say this about running a company- but your comment was a better launching point.
As someone who has run several companies over the last 25 years and has read and or tried nearly ever "method" mentioned... Im now running a company where Im abandoning everything and just going at with skill and fearlessness... and no funding. It feels freeing, and we are growing.
Hm, no, in F1 they don’t have the same car. Each season, each team builds their own (adhering to the Formula) and put massive amounts of efforts to gaining efficiency through engineering.
Oh really?! I said my statement was oversimplified. Not all groups have the same requirements. NASA Spec is very regulated for instance... But I knew a comment like this was coming, so as someone who grew up with a family race team, has a race car, and builds a motorsports app. Shut up.
In National Stock Car Racing the cars are all nominally equal, that’s far from the case in F1 where some years a single competitor dominates partially from having chosen a superior technological implementation.
I don't really follow NASCAR, but from listening to my (huge fan) father-in-law, that word is doing some work. His best (or, at least, my favorite) are the creative ways teams find to bend the rules - or blatantly cheat! - to give their cars an advantage.
One that made me laugh: a team once packed their suspension tubes with lead shot to make minimum weight. On the first lap the driver pulled a lever that dropped all the shot onto the track, and then enjoyed an underweight car for the rest of the race! They're always looking for "legitimate" optimizations, too.
I can't think of a single race where drivers are required to drive "the same car", by any reasonable definition of same. Not stock cars, F1, Nascar, demolition derby...
You all are being idiots. Im done. There is so much nuance to all of this that I did not include. Key words are Flattened by Regulation... Have you ever read a damn rule book? Stock, improved, modified, class, my god.
Good bye, never again. Hacker news is a lost cause.
A car race is a zero-sum game, which is not the case of economics (according to orthodox economists at least), so if there was a magic recipe for startups success, more of them would generate wealth, the pie would grow, therefore less should die?
Yes, and indeed more startups are addressing more markets every year. The total number of attempts and successes are both up, keeping the success rate fairly constant.
I think the total light output of each bulb in the pair is the same at all points in time, but the orange-blue gradient is reversed. So when one is orange at one end, the bulb beside it is blue at that end.
IIRC, the end that's negative looks orange, because the electrons emitted from the filament haven't gotten up to speed yet and can't ionize the mercury atoms at that end to the highest states.
If you didn't do this, you'd see 60 Hz strobing when you looked at one end.
You and I look with dismay at the high prices, but remember that a million hospital administrators are high-fiving themselves. So ideas like "just cut waste" are opposed by a large group with a lot more skin in the game.
Heat goes up with the square of current, so putting 10x the current to get 10x the force means 100x the heat.
Still, I think this idea is under-explored. There are probably applications for robots that move really fast, but only for a second before having to cool down.
One scenario: there's a short circuit somewhere, say rats chewing through insulation. This can cause a very high current through the short. A non-inverter 4500 watt 120 volt generator might have 0.2 ohms coil resistance, so the short circuit current can hit 170 volts / 0.2 ohm = 850 amps. When the shorted branch's circuit breaker trips, the inductance in the generating windings wants to keep that 850 amps flowing for at least a few microseconds, and it gets distributed across everything else that's still connected. Depending on what else is connected (hopefully including some surge protectors) the peak voltage can get into many kilovolts.
The circuit is something like this:
voltage source -- parasitic inductor --+- circuit breaker -- short
|
+- circuit breaker -- your PC
More generally, for the previous poster, look at what happens when a magnetic field collapses suddenly, you can get kilovolt spikes. There's probably a ton of YouTube videos demonstrating this in various ways, it sounds like the sort of thing that Electroboom would do. Normally this is handled via snubber circuits which dissipate the energy before it can do anything, but in exceptional cases it could end up going where it shouldn't.
Isn't that essentially what happened? In the 1930s, the channels were allocated at 6 MHz spacing, but only needed about 3 MHz of bandwidth for the luma channel. There might have been some foresight involved, but the gaps between channels also allowed for cheaper, less precise tuners. Then in the 1950s they added a 1 MHz chroma signal on a 3.58 MHz upper sideband, expanding the channel bandwidth to just under 6 MHz.
6 MHz was there from the start. If it wasn't, the CBS field-sequential might have won. Both government (FCC) and industry (RCA) were pushing for a backward compatible system and there was enough bandwidth to pull it off. OP asks what would've happened had chroma been given its own separate, non-overlapping band. That was not possible while maintaining compatibility.
It's easier to ban things before they become entrenched than after. Banning stock trading is hard today because most senators have been doing it for years before getting elected.
I'd be in favor of senators doing prediction markets, just limited to small dollar trades so they can get better at predicting.
