Stock dilution doesn't work like that. If a seed investor invests for 5% at a $10mil valuation, and the company goes 10x (ie. a valuation of $100mil), if the company now raises a $100mil Series K, that means the Series K investor owns 50% of the company, and the seed investor got diluted down to 2.5%. However, the new valuation of the company is now $200mil with the cash that the new investor brought in, effectively making the seed investor's investment worth the same.

It's a smaller piece of a bigger pie.

To answer your question, the right question to ask is why go public when you can remain private? Public means more paperwork, more legalese, more scrutiny, and less control for the founder, and all of that only to get a bit more liquidity for your stock. If you can remain private, there really isn't much of a reason to not do that.

An IPO means selling a whole bunch of people, whereas fundraising rounds pre-IPO mean courting a small number of large investors. I think it's partly a sign of the times that there's enough concentrated capital that you can get enough money from private hands to not need to go the IPO route yet.

> npm scripts make a http call to the npm registry each time they run, which means they are a terrible way to execute a health check.

Is this true? I couldn’t find another source discussing it. That would be insane behavior for a package manager.

It might be referring to the check if whether npm is up to date so it can prompt you to update if it isn't?

That's probably true, but you're describing incentives and social dynamics, not a technological problem. I notice that every other kind of infrastructure in my life that I depend upon is maintained by qualified teams, sometimes for decades, who aren't incentivized to rebuild the thing every six months.
dgoldstein0 · 18 days ago
But why are those teams incentivized to exist?

For roads, brushes, wastewater, sewer, electricity - it's because these things are public utilities and ultimately there is accountability - from local government at least - that some of these things need to happen, and money is set aside specifically for it. An engineer can inspect a bridge and find cracks. They can inspect a water pipe and find rust or leaks.

It's much harder to see software showing lines of wear and tear, because most software problems are hard to observe and buried in the realities of Turing completeness making it hard to actually guarantee there aren't bugs; software is often easy to dismiss as good enough until it starts completely failing us.

A bridge is done when all the parts are in place and connected together. Much software is never really done because - it's rare to pay until we have nothing more to refactor - the software can only be as done as the requirements are detailed; if new details come to light or worse, change entirely, the software that previously looked done may not be. That would be insane for a bridge or road.

We as an industry need to seriously tackle the social and market dynamics that lead to this situation. When and why has "stable" become synonymous with "unmaintained"? Why is it that practically every attempt to build a stable abstraction layer has turned out to be significantly less stable than the layer it abstracts over?
dgoldstein0 · 19 days ago
So one effect I've seen over the last decade of working: if it never needs to change, and no one is adding features, then no one works on it. If no one works on it, and people quit / change teams / etc, eventually the team tasked with maintaining it doesn't know how it works. At which point they may not be suited to maintaining it anymore.

This effect gets accelerated when teams or individuals make their code more magical or even just more different than other code at the company, which makes it harder for new maintainers to step in. Add to this that not all code has all the test coverage and monitoring it should... It shouldn't be too surprising there's always some incentives to kill, change, or otherwise stop supporting what we shipped 5 years ago.

American military doctrine seems to include the assumption that you will always have the manufacturing capacity and the supply lines to get all the materiel you need to the front, that you'll be bottlenecked by something else like manpower.

This works pretty well for fighting limited wars where part of the justification is to develop and maintain military readiness. Would it still be true in a large scale war against China - could you pump out a million drones a day - or would you wish for a doctrine that included reusable drones?

dgoldstein0 · 19 days ago
Good question.

I think something to keep in mind, the US hasn't fought a war on the home front since 1865. The Spanish American war, WWI and WWII, Vietnam, Korea, the Gulf war, Afghanistan, Iraq - none of these were fought on American soil, with the exception of Pearl harbor, which was a navy base, not a major manufacturing site. So we haven't really had to reckon with what happens if our homeland is under fire - sure, we drilled for it during WWII, worrying about Nazi bombers and Japanese sabotage but neither actually happened.

It doesn't look like our wars are going to get closer anytime soon, but modern planes and rocketry have much greater range than in the 1940s the last time we were at war with countries with significant resources. If we ever come head to head with China, their missile capabilities could be a real concern.

> There's no technological reason for app developers to be restricted from using other payment processors

But there is a customer experience reason. As an iOS user, I very much appreciate that I can ask Apple to cancel some bullshit subscription that used to otherwise try to lock me in behind a labyrinth of added friction and timewasting.

Not every problem is technological.

dgoldstein0 · 2 months ago
Perhaps then there should be a subscription API, so Apple could make the nice "see all your subscriptions in one place" UI? Or maybe banks could better offer this as part of online banking for credit cards. Not sure the right place to put this.

Anyhow I do see your point that narrowing user options can lead to better UX - if you actually like all the tradeoffs they make. The problem is if you don't, your SoL. And in this case the trade-off is Apple taking a giant extra cut so... I think it's reasonable that folks don't like that trade-off.

ECC everything?
dgoldstein0 · 2 months ago
Yes. And most server hardware is already at least ECC ram. You may still want some light radiation shielding to prevent the worst, maybe some heavier shielding for solar flares. But beyond that, simple error correction can be baked into the software - ecc the bootloader and filesystem and you are mostly good to go

...XOR?

So it can carry the 2 extra people, it can carry some luggage, it can't carry both, and it can't carry neither?

I waited 40 minutes for a Lyft at an airport because the driver made up a story about an accident and traffic, in the airport. No one else seemed to be affected by this traffic- so eventually I tried booking an Uber. It arrived 3 minutes later.

20 minutes after that the Lyft driver keeps texting me “where are you?!”. Their turn to wait!

Saw later they just started the ride without me and drove to my hotel.

Lyft said “this trip was completed, no refund”. Welp, app deleted.

dgoldstein0 · 2 months ago
I've had several cases of drivers just not picking me up. Reading their time to move anywhere at all, driving away and keep getting further and further away, it driving towards me only to turn some other direction. I always just cancel on them and have never had to pay a cancellation fee. I think once or twice they "picked me up" a block away. I'm pretty sure I was able to cancel or end the ride on that too, definitely was never charged though I don't recall if I had to use the support. But I never let it actually complete the trip when I wasn't riding. But I was always very miffed when anything like that happened as I did not appreciate them wasting my time.

Is this some sort of a scam? The driver cannot even mark the ride as completed without being in the area right? So they have to drive it anyway. I can’t imagine they would be on the platform for long if this happened on a regular basis. I would say it’s probably an accident but how could this behavior be accidental? Someone might accidentally say that they picked you up, but they couldn’t accidentally then drive an empty car to the destination.
dgoldstein0 · 2 months ago
Maybe they picked up the wrong person and neither of them realized?
