It is somehow addressed, but with unreliable wind power sources that ca'n't be controled:

> We’re closing coal plants and building wind farms and it all just has to add up in the end. It’s not a one-to-one

And of course this won't cover the loss of energy, so let's pretend we can do that through "energy efficiency"

>You can make up that power by the way you operate the rest of your facilities or having energy efficiency savings so your customers are using less

Tl;Dr for the energy side: Smoke and mirrors.

> The morale of the story is that I wouldn't trust ANY exchange

Or, more generally, don't trust unregulated financial businesses and/or operating in shady offshore countries.

FTX was both unregulated and based in Bahamas.

> What kind of workloads spawn so many processes that saving microseconds becomes relevant?

With a huge process, you have a timeframe between the child is spawned and it executes exec*() where you typically "do stuff" (such as closing a lot of fd)

During this timeframe the parent process has its universe COW'ed, and each write will trigger a page fault.

The performance impact can be concerning in the _parent_ process.

> As some people say in Brazil, as an architect, Niemeyer was a very good sculptor.

We indeed have a lot of those fancy buildings from famous architects, mostly from the 70s.

They all share a common pattern:

- a repressed artist who became an architect

- a beautiful piece of concrete modern art on the outside and that makes fancy design magazine photos

- an oppressive building and a complete failure in term of comfort/ergonomy

Another example is the "Espaces d'Abraxas". But there are even worse examples when you look at brutalist architecture.

> Because nuclear plants are expensive, and they take a long time to build, financing their construction can also be a significant fraction of their cost, typically around 15-20% of the cost of the plant. For plants that have severe construction delays and/or have high financing costs (such as the Vogtle 3 and 4 plants in Georgia), this can be 50% of the cost or more.

This is why nuclear power plants should be state-sponsored projects. States typically have loans at 0% rate, or even negative interests.

The issue with posix_spawn is that you can't close all descriptors before exec. This is especially an issue as most libraries are still unaware they need to open every single handle with the close-on-exec flag set.

It's inherently inefficient because while the child process does its initialization (pre-exec) stuff, the parent gets page faults for every thread writing into the memory due to COW. This will basically stall the parent and can cause funny issues.

You simply can't. The constexpr environment won't let you have uninitialized variables/memory anywhere. It won't let you access dangling/out-of-bounds pointers either, overflow two-complement types, etc.

> And if you really want it, it's not terribly hard to write

Sure, but basically it means rewriting all structures that rely on a bucket of stuff.

By the way maps often use a large bucket, and rehash in-place can be preferable.

> Which not many do, not unless the allocation is so large as to be in its own dedicated mmap

Do you know a modern operating system that does not have a mremap equivalent ?

On Linux you pretty much use it as soon as you reach large blocks.

> C++ was discussed as having too many undesirable characteristics.

I tend to agree, as a C++ developer. There are many core issues in the language that haven't been resolved and that are unacceptable for kernel code.

My personal pet peeve: C++ is unable to reallocate a new[] region. This makes basically all structures (vector, hashmap, trees...) unusable for large data handling.

> You can with storage systems

There is no such thing as storage systems at wide scale unfortunately

> well also run out of fuel within a few generations

Absolutely. But hopefully fusion will be around then.

> The biggest retaliation the West can make right now is a commitment to a rapid exit at unprecedented speed from the oil economy, in favor of renewables.

You can't exit from the oil economy with renewable such as wind or solar due to their non-predictability.

If you want to stop importing Russian gaz, you need nuclear energy.

Removed from Google Play. But what about the users who fell in the trap ? Will the app be removed automatically ?

Same experience with a bunch of Aquantia AQC-107 (ASUS XG-C100C). Had to remove them from a Linux server, it just won't work and botch IPv6 traffic (especially routing advertisement notices ?!). Got Intel x550t2 and all the issues miraculously disappeared.
