lokar commented on Ask HN: Why hasn't x86 caught up with Apple M series?    · Posted by u/stephenheron

There’s a number of reasons, all of which in concert create the appearance of a performance gap between the two:

* Apple has had decades optimizing its software and hardware stacks to the demands of its majority users, whereas Intel and AMD have to optimize for a much broader scope of use cases.

* Apple was willing to throw out legacy support on a regular basis. Intel and AMD, by comparison, are still expected to run code written for DOS or specific extensions in major Enterprises, which adds to complexity and cost

* The “standard” of x86 (and demand for newly-bolted-on extensions) means effort into optimizations for efficiency or performance meet diminishing returns fairly quickly. The maturity of the platform also means the “easy” gains are long gone/already done, and so it’s a matter of edge cases and smaller tweaks rather than comprehensive redesigns.

* Software in x86 world is not optimized, broadly, because it doesn’t have to be. The demoscene shows what can be achieved in tight performance envelopes, but software companies have never had reason to optimize code or performance when next year has always promised more cores or more GHz.

It boils down to comparing two different products and asking why they can’t be the same. Apple’s hardware is purpose-built for its userbase, operating systems, and software; x86 is not, and never has been. Those of us who remember the 80s and 90s of SPARC/POWER/Itanium/etc recall that specialty designs often performed better than generalist ones in their specialties, but lacked compatibility as a result.

The Apple ARM vs Intel/AMD x86 is the same thing.

It’s a bit unfair to say apple threw out backwards compatibility.

Each time they had a pretty good emulation story to keep most stuff (certainly popular stuff) working through a multi-year transition period.

IMO, this is better then carrying around 40 years of cruft.

That still doesn't make sense, the Government is paying people to be in the military.

My point was really that "socialism" (in common use, especially on the libertarian right) is not really tethered to any historical definition. It's a political term to attach to things you don't like.

Nothing is "guaranteed", so no. People usually congregate where resources exist, that's often why towns are where they are, near water for example. Where I live for example, freshwater comes from a pretty stable water source. Paying the municipality to operate and maintain that is as close to "guaranteed" as it gets probably.

Once the circumstances change, we'll have to adapt.

Water law in the US southwest is wild. The right to flows of water, into the future, is treated as a private property right and is bought and sold. Municipal water systems normally acquire the rights (and arrange transport).

Do ordinary homeowners ever pay for guaranteed access to water? Surely not, right?
lokar · a day ago
Yes, in a way. They live within the bounds of a water district, which itself has water rights. These districts limit use (or the growth in use) by passing rules on the use (limiting the watering of grass, for example), or (fairly often in some places) limiting new service hookups. They won't let you connect if they don't think they can secure the supply long term.

This thread is getting weird and with a lack of understanding; There's absolutely no reason to have a negative attitude to people wanting to buy water. I grew up 5mins from the largest shopping center in the southern hemisphere and we still had to occasionally buy water when there was a drought since we were on a rural stretch of road just off the main highway.

You don't have to live far out of town to have no town water. The pipes don't go far out of city/town limits at all.

You always get periods of prolonged drought even in otherwise perfectly reasonable self-sustainable properties.

This isn't some "HAHAHA suck it libertarians" attitude. This is a "anyone who lives slightly outside of town wanting to buy water and being told no" type of situation.

I don't have a negative attitude towards people who live off wells, or local surface water, or some place that sells it to tank back.

What I have a negative attitude towards is developing housing in an area of the arid western US without access to water. Water rights (the right to buy water) has controlled development here since before statehood. It's very simple: you don't develop without water rights, it's irresponsible and puts an unfair social burden on others.

Massive amounts of groundwater are being sucked out of Colorado by Chinese and ME companies that, for instance, grow alfalfa crops and then ship them to their home countries.

Exports of alfalfa should not be allowed

The land is cheap in the San Luis for a reason. It can't support much life. Ultimately these are not multi-generational folks being driven out. They are newcomers who have overwhelmed the existing infrastructure.

And access to utilities is on of the only tools that counties have to discourage unsustainable development.

Not every part of the continent should be covered with homes.

After reading the article I come to the conclusion that this was never really about water. There wasn't even a water shortage, only a technical issue that would be resolved.

This was about some people on the waterboard not being able to manage angry - semi-aggressive- people properly.

And now those people can irrigate their lawns while others can't even drink, wash or cook.

I agree, none of this was really necessary. The board/city was broadly within their rights not to sell (and down the road, as water supplies become more strained they may in fact not have extra water to sell).

But the board handled the situation very poorly. The job of being on a board like this is often to sit patiently while people complain and perhaps yell. Try to keep things calm and moving along, let everyone make their statement.

They should have just accepted the feedback and then scheduled discussion on various options for some future meeting, with a final vote even further out.

They paid the municipality for the water, but they didn't pay the municipality. Got it.

There is a very real legal and practical difference between paying for 100G of water, and paying for the right to buy 100G per week for the next N years.

Both have a price in the American west, and they did not pay the latter price.

Do workers in the military control their means of production? If not, there's no relation to socialism.

In modern US politics, "socialism" is the Government giving people anything for free.
