I disagree with the author's point that CPU instruction sets should expose more of the CPU's implementation. This has been tried in the past and failed to work long-term. One example of this is branch delay slots from some RISC processors (such as MIPS and SuperH) designed in the late 80s and early 90s. For those unfamiliar with the concept, it basically means that the instruction after a branch instruction will get run regardless of if the branch was taken or not. This was a short-term benefit, as it meant the job of avoiding pipeline stalls after a branch was left to the programmer, so the processor could be simpler and cheaper than designs without them. However, as time went on, the processor designs evolved with more complex pipelines, so the single instruction wasn't enough to cover the branch delay. Instead, it became a legacy issue that future processors had to deal with for compatibility reasons and made their branch prediction and pipeline logic more complex.
Wasn't this also similar for itanium? Where the branch burden would be on the compiler?
I'm sorry but you are dangerously wrong.
Not only are there enormous protections with the mis-use of one's credit card, but the 'password'/card number is randomly generated and not used elsewhere.
A regular person is quite likely to reuse their favourite password for their bank login and therefore expose most of their other services when Plaid is inevitably hacked, or more likely, when someone pretends to be Plaid with typosquatting and the user has learned that giving passwords away is OK.
> Not only are there enormous protections with the mis-use of one's credit card, but the 'password'/card number is randomly generated and not used elsewhere.
Not true. My mother got a free credit card that she never used and never even took out of her safe box, and a few weeks ago someone used that card to buy a Microsoft gift card. Luckily for her, she regularly checks the bank's statements.
I'm convinced there's a workaround to buy stuff using just the numbers, because that's how cards used to work a few decades ago.
Of course they have those barriers.
The incentive for managers is to promote.
Perhaps if managers had budgets of dollars instead of budgets of headcount then the imbalance wouldn't be as large, but AFAIK companies do not do that except at very high levels.
Having a dollar budget would make the imbalance worse unless ideally they don't get away with moral hazard. The issue is usually having managers taking all the benefits and none of the risk, and that's bad.

Totally, and I get that. We've got people in this thread who are saying that non-ECC ram shouldn't be trusted [0], or that it should be standard [1]. I get the use cases, but why do I want that on my workstation.
> your code won't compile because variable names got flipped.
I have _never_ seen or even heard of this or anything vaguely resembling this happening. Are there any writeups of this anywhere at all?
In my opinion yes, ECC should be standard.
ECC is expensive just because Intel had a monopoly over the server segment, and unilaterally forced desktop not to use ECC.
Otherwise people would use desktop computers as servers, and that would reduce profits.
At work, my workstation Desktop computer has ECC. The colleague's sitting next to me has on their screen sometimes kernel warnings of ECC errors.
And cases of bit flips happen every day, that's why some problems are solved by just restarting your computer or the software. I'd argue that many times we blame software bugs on pure hardware bit flips.
Here's a story of a variable name bit flip: https://alexbakker.me/post/did-cosmic-rays-break-my-linux-bu...

I have a genuine question - in practice on a workstation/developer computer, what sort of protection does ECC ram give me?
I've got two daily driver machines - a 3970x threadripper with 96GB ram, and an M1 Macbook Pro - neither of which have ECC ram.
I've been using them both for over 2 years, and not once in that period (that I'm aware of) have I found myself with a problem due to faulty RAM, but I do regularly find myself wishing both were faster.
What practical benefit would I get in exchange for the performance hit of ECC memory?
It depends on your workload.
Some industries require to be able to reproduce exact bit by bit data.
Anything that requires absolute bit certainty, for example digital signatures, encryption, or financial information, will require ECC.
If you don't care if your files eventually don't match a sha256 checksum, you'll be fine. for example source code, it doesn't matter because in the worst case, your code won't compile because variable names got flipped.
And even then, if you're using Git for source code control, you're already using hash signatures to detect data corruption, as well as a very large redundancy and replication. Git is, in a philosophical way, ECC by software.

Argentinian economics at its best. Let's hope Egyptians come to their senses and realize that they can't get us dollars out of thin air and controls such as this will Only make it worse.
Ha. So lie and then when called on the lie, presume the person who called out the lie is “missing the point”.
Goalposts, rocket mode, launch!
Is the insulin cheaper now? No.
How did insulin become so expensive? It seems relatively straightforward to produce and the inputs are cheap
Government regulations. It's as easy as allowing to import it from cross the border from Mexico and Canada.
Another profitable industry besides mining could be setting up nursing homes on the moon, where wealthy elderly folks could live fuller lives due to the reduced gravity. Yes, the idea of this only being available to the super-rich (at first) is nauseating to me too, but if it provides the source of funding to establish sustainable moon bases, that would be incredible, and other industries could follow afterwards, including e.g. new sports leagues such as low-gravity basketball and soccer.
Eventually, enough people would be living on the moon as helpers for the wealthy folks and athletes that eventually there would be so many working-class people on the moon that secondary and tertiary industries would spring up to provide products and services for the working-class people. Soon enough it would become profitable to farm crops on the moon (for lunar consumption), build products on the moon (for lunar consumption), and more.
We'd eventually get to the point where a lunar nation could have positive GDP and be economically self-sustaining. It would be a trade partner with the terrestrial nations, and be the first new nation to step beyond Earth. Generations of people will get married and be born there, and humanity would be a step closer to settling the cosmos.
That's what SR Hadden did in Contact ;) as always, Carl Sagan is still teaching us to this day
