I want to flip coins so randomly that I never see the same face twice in a row.

This is an interesting insight. The OP's constraint that no two adjacent squares are the same color ensures non-randomness. (Which reminds us why people are so bad at producing "random" sequences.)

PG is an excellent writer, but this essay seems remarkably misleading. The unstated premise seems to be that well-educated adults already know everything they want/need to know about everything, which is silly. I'm older than PG, and pretty well educated, but I am constantly learning new things. I don't think it's because they are not important or I am obtuse. I think it is because I am (still) intellectually curious.

Sometimes I learn new things because they are new. And sometimes I learn new things (that are well known to people in other fields) because while I know a lot about some things, I know very little about others -- so little that I don't even know those things overlap with my interests.

Those of us who enjoy learning appreciate that we will never know everything we would like to, and in fact we will never know the boundaries of knowledge for topics we care a lot about. It's not that it is unimportant to us, it's just that we hadn't learned about it yet. That's why we read essays.

Every system has problems. The better question is: what is the acceptable threshold?

For an example Medicare and Medicade had a fraud rate of 7.66%. Yes, that is a lot of billions, and there is room for improvement, but that doesn’t mean the entire system is failing: 93% of cases are being covered as intended.

The same could be said with these models. If the spoilage rate is 10%, does that mean the whole system is bad? Or is it at a tolerable threshold?

In the protein annotation world, which is largely driven by inferring common ancestry between a protein of unknown function and one of known function, common error thresholds range from FDR of 0.001 to 10^-6. Even a 1% error rate would be considered abysmal. This is in part because it is trivial to get 95% accuracy in prediction; the challenging problem is to get some large fraction of the non-trivial 5% correct.

"Acceptable" thresholds are problem specific. For AI to make a meaningful contribution to protein function prediction, it must do substantially better than current methods, not just better than some arbitrary threshold.

Not a lawyer, but there are a lot of crimes that are not felonies. Speeding 10 mph above the limit in a 65 mph zone - not a felony. Reading hacker news for an hour during work time and not being paid $800/hr - not a felony. Calling in sick when you are hung over - not a felony. There is no federal tax on gifts for the giftee. Indeed, I suspect there are a surprising number of crimes that could get you jail time that are not felonies. Insider trading - it’s a felony, which is why people in companies with insider trading information are told they cannot trade at certain times.

I’m pretty comfortable believing I have probably not committed more than two or three felonies in my life. (Don’t want to find out I am wrong.)

Let's see: C elegans -- the worm no computer scientist can crack S. cerevisiae -- the yeast no computer scientist can crack E. coli -- the bacterium no computer scientist can crack HIV -- the virus no computer scientist can crack

Has a computer scientist cracked any complex system that was not engineered?

fastaguy88 commented on NIH has rescinded its scientific integrity policy   bsky.app/profile/lizborko... · Posted by u/doener
fastaguy88 · 5 months ago
If you read the Final Scientific Integrity Policy, included towards the bottom is the statement:

"and under “Protecting Scientific Processes,” a statement noting that early termination of extramural awards is prohibited except under certain specific circumstances."

Clearly, this is not a policy that the current administration commits to.

"Even though it's not designed to"

It is designed to, though. That's the thing. The line is arbitrarily drawn at not getting CLI/root access to your iPad.

His point is that over the years, Apple has blurred that line a lot. You can use keyboards and mice. You can do all your daily computing on an iPad - email, spreadsheets, YouTube, whatever.

But it's still locked down, for whatever reason, despite being a perfectly capable computer that doesn't necessarily need to be.

It's honestly really obvious what he's saying. iPads have changed over the last 5 or so years, and people on HN clearly haven't used one in a while. The author isn't _wrong_.

Apple spends all this effort to blur the lines between personal computer and a device you can compute on, and it mildly tricks users who don't necessarily realise there's a difference between the computer and the tablet, especially amongst younger generations who grew up on tablets ("iPad kids").

Your concept of designed is very different from mine. The iPad is capable of providing a shell interface, but it is clearly not designed to. It is designed to provide a secure media consumption experience. There is nothing arbitrary (from a mass consumer security perspective) about not providing a shell. Providing a shell makes it much easier for bad actors to dupe unsophisticated users.

I am very puzzled. Apple has locked you in a cage because you bought an iPad to replace a MacBook? What is the cage, and why weren’t you the jailer?
fastaguy88 commented on How did places like Bell Labs know how to ask the right questions? (2023)   freaktakes.com/p/how-did-... · Posted by u/sebg
fastaguy88 · 6 months ago
I think it is worth pointing out that Bell Labs was an Engineering research lab. Scientists there created new disciplines, but in the service of relatively well defined engineering goals.

Contrast this with the NIH, where the science also has a goal - improving human health - but the system to be improved was not engineered. Curing a disease, which has a natural origin, is quite different from improving communications channel capacity.

I suspect that managing engineering research is much more amenable to process analysis than research on biological systems.

I think, however, the total count is extremely important.

Every University’s purported mission is to educate students and advance our collective knowledge together with its students.

That’s it.

If the university makes more money from treating patients than teaching its students, then its mission can’t help but shift.

Likewise if the bulk of the staff are not focused on teaching and educating, then its mission can’t help but shift.

This is a problem.

Not if the university has a medical school. Virtually all R1 universities with medical schools have a hospital, and a large clinical practice. Most of medical school is an apprenticeship where you treat patients. Medical schools need patients, which means a lot of additional staff.

Likewise, in most fields it is no longer possible to advance knowledge just by going to the library or writing on a white board. Knowledge is advanced through experimentation, and experimental equipment and reagents cost money, and need staff to use and maintain them.

No university (and certainly no medical school), makes enough money in tuition and fees to pay for the education provided, and I seriously doubt that many universities have supported themselves solely through tuition since the beginning of the universities in the middle ages.

You are certainly correct that university deans and presidents have seen their mission shift with the increasing cost of education, and indeed faculty are writing many more grants than they did 75 years ago. So time commitments have shifted. But there is an implication that it could have been some other way -- that the money is there (or could have been there) if some other path were chosen. It is hard for me to imagine where the money might have come from.
