oldgradstudent··on Superconductivity scandal: the story of deception in a physics lab
Measuring the wrong thing, even if it is highly correlated to what you really want to measure, often results not in a slightly suboptimal result, but in the worst possible result.
oldgradstudent··on FDA clears first over-the-counter continuous glucose monitor
> My wife, who is a physician, thought it might be hypoglycemia, since i'm at high risk for diabetes.

Isn't hypoglycemia a side effect of insulin and other glucose lowing agent rather than of the diabetes itself?

oldgradstudent··on The Pile is a 825 GiB diverse, open-source language modelling data set (2020)
It also contains an archive of opensubtitles, which is also not very open source.
oldgradstudent··on Global Economy Approaches Soft Landing, but Risks Remain
As long as the chairperson of the Federal Reserve doesn't say that the economy is fundamentaly sound[1], I think we'll be OK.

oldgradstudent··on Twenty years is nothing
> There's a LOT of room for improvement, but there's no profit incentive for improvement, and let's be honest, git is very nice at it's price point, so we're likely at a local maxima for a while.

There was no profit incentive for creating Git. It still got created and became popular.

It's just that Git is far closer to good enough than what came before it - many of those were true horrors (I'm looking at you ClearCase).

oldgradstudent··on Behind Apple's Doomed Car Project: False Starts and Wrong Turns
> I was going to say exactly the same thing. This is precisely the issue with UX-led processes. When you're dealing with very hard engineering problems, you really don't yet know enough to be designing a product.

It's like the Wright brothers, before working on the Kitty Hawk, worked on mocks up of an online ticket ordering system.

oldgradstudent··on Behind Apple's Doomed Car Project: False Starts and Wrong Turns
> Mr. Ive and his team of designers drew concepts for a car that would look like a European minivan such as the Fiat Multipla 600, which has a half-dozen windows and a curving roof. It had no steering wheel and would be controlled using Apple’s virtual assistant, Siri.

> One day, in the fall of 2015, Mr. Ive and Mr. Cook met at the project’s headquarters in Sunnyvale, Calif., for a demonstration of how the car might work. The two men sank into the seats of a cabinlike interior. Outside, a voice actor read from a script of what Siri would say as the men zoomed down the road in the imaginary car. Mr. Ive asked Siri what restaurant they passed and the actor read an answer, said two people familiar with the demonstration.

Tackling one of the hardest technical problems ever attempted, where it was not clear at all whether a solution is even possible (it is still not clear) they seriously discussed the script Siri would read.

oldgradstudent··on Boeing missing key elements of safety culture: FAA report
It has little to do with "shareholder value".

The original sin is paying executives with stocks and especially stock options. It creates catastrophic and corrupting incentive structure.

Their incentive is to raise the stock price long enough to sell some amount of stock options. The company be damned.

There are many examples, but the classic one is Dick Fuld, the CEO of Lehman Brothers. He drove Lehman Brothers into Bankruptcy all while becoming dynastically rich.

oldgradstudent··on Early humans had ADHD, scientists say after making people play game online
That's simply wrong.

While life expectancy at birth has increased a lot, that was mainly due to infant survival rates. Life expectancy once a person reaches, say, 25, has not increased by that much.

Diabetes type II was vanishingly rare not long ago. Now we have teenagers suffering from it. Teenagers with Diabetes type II is not due to humans living significantly longer.

Similarly with dental caries, which is quite common in childhood these days. This is not due to people living significantly longer.

Similarly with Cancer. There are cancers that are relatively common in young people today. Testicular, or breast cancers occur quite often in young people. Missionary doctors in Africa, among the native Americans, or the Inuit, report not diagnosing a single case of cancer for years. It is not a matter of diagnostic failure. An untreated late stage breast cancer or testicular cancer is quite easy to diagnose.

oldgradstudent··on Early humans had ADHD, scientists say after making people play game online
> Wouldn’t its very reliable high prevalence across a wide diversity of today’s gene pools strongly suggest an early, not late or isolated, origin?

There are plenty of things which are common across a wide diversity of today's gene pools that, as far as we know, were rare in the past.

For example: Type II diabetes, Dental caries (pre agriculture), or Cancer.

oldgradstudent··on Ask HN: Cleanest way to manage Windows OS?
> However, you as a person will only have 1 machine.

1 machine at a time.

A configuration allows you to setup a new machine quickly and consistently when one breaks, get stolen, or lost in an inconvenient time.

More importantly, as a developer you want a clean and consistent development environment so that you do not depend on anything accidentally installed on the machine.

In a previous project, development was tied to a specific machine and until I fixed it, the team simply could not migrate to a new machine if anything happened to it.

> Why's that? They can get the weight down to barely more than glasses

Even after 36 years of wearing glasses (current ones weight barely 20 gram), they still bother me, and I fiddle with them constantly.

oldgradstudent··on Show HN: Multi-monitor KVM using just a USB switch
There are pretty reasonable 4-port KVM switches on Aliexpress that support 60Hz 4K and USB-3 for $55 or even less.

I got this https://www.aliexpress.com/item/1005002941646654.html a year ago. It has some minor compatibility problems with my Macbook Pro (or Apples' multiport adapter) which require me to remove and reinsert the USB-C cable from the Macbook once in a while, but it otherwise works very well.

A year later, there are multiple such devices starting from $30, or even less.

> WSL is what happened, and when it couldn't do some things they built WSL2.

I always wondered why it wasn't called WslEx.

oldgradstudent··on "Fake Chinese income" mortgages fuel Toronto real estate bubble: HSBC bank leaks
- "A rolling loan gathers no loss."

As long as real estate prices continue to rise, you won't see large scale missed payments because they will be able to sell the assets, refinance the loan, or even successfully rent it out.

We've seen this dynamic in 2008 and in the S&L crisis before. Bad loans drive the bubble, the expanding bubble hides the bad loans, but when the bubble stops, there is a massive large scale loan failure.

oldgradstudent··on 23andMe's Fall
How could a company, that provided me the amazing insight that I have 71% likelihood of having little or no back hair, fail?

BTW, I have quite a lot of back hair. Most of the other physical features are wrong.

oldgradstudent··on Intel's Humbling
They didn't simply miss the boat on 64 bit.

That was an intentional act to force customers into Itanium, which was 64 bit from the outset.

oldgradstudent··on Intel's Humbling
> I thought that Krzanich should do something similar: Intel should stop focusing its efforts on being an integrated device manufacturer (IDM) — a company that both designed and manufactured its own chips exclusively — and shift to becoming a foundry that also served external customers.

That would only work if Intel has a competitive foundry. Intel produces very high margin chips. Can it be competitive with TSMC in low margin chips where costs must be controlled?

The rumors I've heard (not sure about their credibility) is that Intel is simply not competitive in terms of costs and yields.

And that's even before considering it doesn't really have an effective process competitive with TSMC.

It's easy to say it should become a foundry, it's much harder to actually do that.

oldgradstudent··on Everyone hates the electronic medical record
When my Israeli health care provider switched to electronic records in the mid-late 1990s, a typical medical appointment had two parts, roughly similar in length.

During the first part, the doctor would complain about how the system crashes, how hard is it to type with two fingers, and how computers are pointless. In the second part, I’d complain about my flu/cold symptoms.

oldgradstudent··on Nearly 30% of Gen Z adults identify as LGBTQ
Yes, While the Gay and Lesbian category is now 18% (5% of 28%) of LGBT according to this survey.

MY point is that the Gay and Lesbian category remained constant from the previous generation.

oldgradstudent··on Nearly 30% of Gen Z adults identify as LGBTQ
> I would assume another gigantic percentage is also L or G.

That would be a bad assumption.

According to Figure 1 of the report:

* 15% Bisexual

* 5% Gay or Lesbian

* 8% Something else

The Gay or Lesbian category is essentially the same as in the millennial generation.

oldgradstudent··on The incredible shrinking podcast industry?
The podcast industry is not shrinking.

It was never that big in the first place, apple simply made it clear.

oldgradstudent··on We switched to Java 21 virtual threads and got a deadlock in TPC-C for Postgres
Java virtual threads did not cause a deadlock here.

The deadlock was a usage error.

A better title would be: Naively switching to Java virtual threads caused a deadlock in TPC-C for Progress SQL.

oldgradstudent··on Rethinking Diabetes – interview with Gary Taubes
If you can rigorously test your hypotheses in an experiment, it is a scientific field.

If you can't, or won't, it is not a scientific field.

oldgradstudent··on Chinese researchers claim they can break 2048-bit RSA using quantum computers
No need for any extraordinary proof.

Start by factoring the RSA Factoring Challenge.

https://en.wikipedia.org/wiki/RSA_Factoring_Challenge

Obviously there are ways to cheat on this challenge, such a cyber attack on where RSA Inc. stores the results, but it would be a great start.

oldgradstudent··on Discontinued and unreleased Microsoft peripherals revived by licensing deal
My first mouse was a Microsoft Mouse bought around 1987. It continued working for many years and I've only stopped using it because screen resolutions increased too much for it to handle.

https://deskthority.net/wiki/Microsoft_mouse_(3rd_gen)

There is something about the way the buttons and scroll wheels feel that no other manufacturer could match. Not even Logitech.

oldgradstudent··on iPhone that fell from hole in Alaska 737 MAX flight is found, still open to Mail
> No screen crack is pretty good though. Smartphone screens have gotten crazy good recently

It looks like it has an intact screen protector. The impact does not appear to be that strong.

oldgradstudent··on iPhone that fell from hole in Alaska 737 MAX flight is found, still open to Mail
Not in airplane mode, though.
oldgradstudent··on Apple starts sending 'batterygate' settlement payments
Because they would have had a class action suit for selling phones that only last a year or so.

It is far easier to notice a phone that dies in you than something as vague as it progressively becoming slower.

It looks to me they simply hoped nobody would notice it was intentional.
