> 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.

That's what SR Hadden did in Contact ;) as always, Carl Sagan is still teaching us to this day

frankreyes··on The U.S. Government Has $5B in Bitcoin
That's almost 1% of total BTC supply

Wasn't this also similar for itanium? Where the branch burden would be on the compiler?
frankreyes··on Google is going to court for the first time over alleged pay discrimination
> 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.

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.
frankreyes··on ECC RAM on AMD Ryzen 7000 Desktop CPUs
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...

Bit flips usually affect operating system stuff, here's another story: https://blogs.oracle.com/linux/post/attack-of-the-cosmic-ray...

frankreyes··on ECC RAM on AMD Ryzen 7000 Desktop CPUs
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.

frankreyes··on Egyptian banks suspend debit card use in foreign currency
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.
frankreyes··on California governor vetoes bill that would have set a $35 cap for insulin
Is the insulin cheaper now? No.
frankreyes··on California governor vetoes bill that would have set a $35 cap for insulin
Government regulations. It's as easy as allowing to import it from cross the border from Mexico and Canada.
frankreyes··on California governor vetoes bill that would have set a $35 cap for insulin
Either die for sure from lack of insulin, or have a chance of not dying by crossing the border. The math checks out
frankreyes··on California governor vetoes bill that would have set a $35 cap for insulin
You're missing the point. The insulin is the point. And the insulin is still expensive.

It would be easier to just import it from the border, either Mexico or Canada.

frankreyes··on Chicago independently abolishes subminimum wage for tipped workers
The difference is temporal: tip is for a "past" already rendered product or service. Sbf, Holmes, et al, it's about a promise for "future" services, which have a risk associated of no delivery or render. When you've already eaten your burger there was no risk of uncertain delivery. The causal relationship is reversed
frankreyes··on Delta finds fake jet aircraft engine parts with forged airworthiness documents
We need new rules that improve enforcement. And then enforce the enforcement with rules about enforcing enforcement!1

That's the thinking of bureocrats who see the world in terms of rules and enforce, but fail to see the bigger picture that it's easier for everyone to just relax the rules.

frankreyes··on Tell HN: Please stop sending AI-generated job applications (whoishiring threads)
Cover letters were required 100 years ago when CVs and resumes had to be delivered by postal mail and the secretary of the company had to direct the CV to the right application and job description, and phone calls or face interviews were not available or practical, because travelling took literally days.

Cover letters are literally a "cover" to a resume saying why are you sending that resume.

Today, that's just the subject of the email with the resume as attachment.

Today, cover letters provide no value to any involved party, and as you can see they can be easily played and manipulated. You're just adding more hoops to your own detriment.

frankreyes··on I got robbed of my first kernel contribution
> The developer could have accepted that allegedly inferior fix, give the credit, and patch it with their own version in a single commit.

My best oss contribution was done exactly like this. Someone else reviewed my code, made some changes, but my name was on the commits. I was happy that someone else took the time to make my code better and at the same time, keep my name on it.

frankreyes··on 64-bit bank balances ‘ought to be enough for anybody’?
Many decades ago I worked in a Java team who they were using some money as a double and some as a BigDecimal. When I asked why, ... they said that at the start they didn't think they'd have any issue with doubles. Years later and still had lots of tech debt because manually rounding doubles to BigDecimal.

Isn't this the same reason people used to drink lots of alcohol? Because whisky is safer (Short term) compared to non drinkable water?
frankreyes··on Why agencies get stuck at $50k MRR
> This happened here in Germany and it was an awful time.

Because you didn't diversify your economy. Just like my last sentence said.

Sorry about your country but my ex wife is German and... yeah, sorry. You didn't learn your own history.

It's funny because I'm argentinian and we don't diversity our risks either. And now Germany is comparing themselves with Argentina:

https://www.thetimes.co.uk/article/germany-sick-man-europe-e...

>> This year Germany’s GDP is forecast to shrink by about 0.4 per cent, the worst performance of any large country in the eurozone and any member of the G20, with the exception of Argentina.

frankreyes··on Why agencies get stuck at $50k MRR
The more clients, the more chances that any will leave. That's called variance, aka, risk.

Economies of scale reduce or help the amortization fixed costs, not variable costs.

Economies of scale have more risk. The right approach is to diversify the risks.

frankreyes··on Why agencies get stuck at $50k MRR
Some companies solve this with Franchises. Others with performance linked bonus.

What other options do we have?

Yes, They probably run some cash numbers internally and realized that forcing everyone to pay would be the only plausible way to make money
frankreyes··on Removing garbage collection from the Rust language (2013)
Thanks, never wrote Rust so I'm just guessing. What else there is, besides static type checks? Is there a runtime side too?
frankreyes··on Removing garbage collection from the Rust language (2013)
Rust just took C++ std::unique and std::shared ptr and made those integrated directly in the language, and the only option for allocation. Which is awesome.

It would be nice to see if we can have a sub set of C++ that forces us to only use std::make_unique or std::make_shared calls.

frankreyes··on Appeals court rules White House likely overstepped 1st Amendment on social media
That is not true. Face masks at the start of the pandemic we're Forbidden and only many months later became mandatory. The amount of misinformation that came from official sources is ridiculous.

It was so funny to suddenly see the Surgeon General in the USA saying that face masks and coverings are useless, to creating a YouTube video showing how to make one yourself using a rubber band...

https://youtu.be/PI1GxNjAjlw?feature=shared

We know Today that face masks are useless, because it's not the first time we have a large scale virus. Sars and Mers a decade ago gave valuable information which official sources ignored.

One of many sources:

frankreyes··on Huawei teardown shows chip breakthrough
Yes. I understand your logic. But Truth and Facts are two different things.

We have no evidence that China has actual real capacity to mass produce those phones for mass demand.

As other comments say, it may well be chips that were manufactured before sanctions, or chips manufactured on low scale.

The second point is why Global Foundries dropped the chip race, and why TSMC is the global leader.

And under sanctions, I see no reason why China would suddenly become better at mass production than TSMC.

China has a long tradition of inneficiently throwing money at things, so their chips may also be on a very low yield wafers and heavily subsidized. That's not sustainable either

frankreyes··on Huawei teardown shows chip breakthrough
Scale. The point is the scale. You can easily make one wafer in a laboratory, but to make wafers at scale of economics is a totally different thing

China: 5%

Taiwan + Samsung : 71%

frankreyes··on Huawei teardown shows chip breakthrough
Is that a wafer? That's how chips are made in a laboratory. Good luck on the yield

China: 5%

Taiwan + Samsung : 71%

https://www.cnbc.com/2021/03/16/2-charts-show-how-much-the-w...

5% is hardly being at scale.

Let's support our claims with evidence

frankreyes··on Huawei teardown shows chip breakthrough
Yes, using imported equipment, tools, labour, QA, know how and management staff. They just rubber stamp the made in China seal. And data supports that claim since it's Taiwan the world producer of 7nm chips.
