It's interesting reading about WWII generals because they're so well-studied it's relatively easy to notice patterns about them. One is that there were a few different types based on what they were good at. Patton was a good tactician and (mostly) beloved by his men; Eisenhower was a logistician with little experience actually commanding but he got along with everyone; Nimitz was good at delegating (aka finding the right man for the job); etc. A lot of leadership stuff is universal, but then a lot of it is also dependent on what's needed for the job, and a person's skills and leadership patterns may not be exactly what's needed for the job. The Peter Principle is that if you do a good job you get promoted, as you get promoted it gets harder, eventually you reach a point where your skills aren't enough to overcome the next level of difficulty increase. Most people would probably be able to go a lot further if they were fit into the right positions to use their particular leadership pattern
I also have always slept with our child in our bed. This hasn't done much for my sleep.
Is this sarcasm or a joke? I honestly can't tell, but I hope it is.
Shazam was founded by an American living in California. It releases first in the UK under a UK business though. I don’t see that as counting
I think they are referring to hackers. So - as a hacker you only need to slip up once to possibly be found by a group of average folks working 9-5 to catch you.
The only “secret sauce” is the liability shift. Traditional online and contactless payments are classed as “cardholder not present” transactions which place more liability for fraud on the merchant.

Apple and Google Pay (and other bank-provided payment apps) use biometrics to confirm cardholder authorisation, switching a subset of payment types to cardholder present.

This means some chargeback types are instantly declined, and others have a lower requirement for merchant proof.

This is all part of the card network standards, which are freely available if you’re interested from https://www.emvco.com/

The reason there’s no open source option is the requirement to certify the implementation’s security, so you need a commercial entity to work with the banks. Oh, and every bank has to integrate separately - that’s a lot of banks to talk to.
I'd like to see CHERI succeed, along with support in more processors and operating systems.

Certainly Apple should be able to implement it (or something similar) both on the hardware and software side.
Apple Pay is also somewhat different from contactless/chip payments on a card because it's authenticated, whereas (US at least) cards are not authenticated since we don't use PINs.

IIRC in some countries this means it's accepted more or has higher payment limits.
I couldn't convey the technicality across, but the bad experiences I had were mostly localized in course 6 classes - Intro to Algorithms, Design & Analysis of Algorithms, Intro to Machine Learning. I actually did very well in math & physics because Office Hours were much more available, and they tried teaching in different formats (e.g. TEAL).

>incredibly open policy on working together
Yes this was mostly the case - except for course 6. Also, I - sadly - didn't have study groups. For a combination of reasons, including my flaws, I just wasn't good at making friends in college.

As for how it's different from a job board with zoom - the key is to solve the "scarcity" issue, in my opinion. Teaching 1-on-1 for n students scales O(n). If there's a way to teach n students O(log(n)) i.e. address all overlapping needs with videos that can be replayed infinitely, then address remaining personalization problems, that's the approach I believe in

If promotions are based on metrics (and they always are, even if the metric is "how much do I like this guy"), then you can either try to increase your score in that metric as much as possible, or you can game the metric as much as possible to make it look like your score in the metric is high. Most of the people at the executive level have been doing the latter so long that the former just isn't really considered at that level
To what degree do lawyers actually want to track their time accurately?

I used to work a timesheet intensive job (consulting). The quiet rule was log the minimum 45h/w if you like your engagement; log your actual hours if you hate it.

When my lawyer bills me 1 hour, I know it doesn’t actually take him 1 hour. That’s just his rate. This has been my general experience with small shops. Do bigger firms pay closer attention to detail?
Occupation is very labor-intensive. The Allies did it after WWII.[1] It took a huge number of Allied troops, and continued until 1952.

Because ChatGPT ships with a system prompt which instructs the underlying model to do exactly that. A similar web application could be developed for Claude, and it would perform similarly with the right prompt, as it's quite good at tool use.

For example, I'm able to get Claude-3-Opus to write Python and call a Python interpreter of its own accord when questioned about time series data in some of my data analysis workflows, though I haven't glued together a pretty GUI for it yet (e.g., plots are simply saved to disk). While I haven't run into any problems around calculations yet, I'm sure it wouldn't be too hard to further refine the system prompt and ensure that all calculations are performed or checked using Python.
So true. I bought a Saturn a month ago after hearing and reading much about it for years, and the thing still works perfectly. I even bought a stack of CD-R to burn some "backups", and not a single read error. I was expecting to have laser power issues, but nothing, it just works.
Long time ago I did some first-hand research on speed dating results and read a lot of papers. I am not familiar by the recent research, but I find it unlikely that the behavior of people would have changed dramatically.

I found that when we look at the behavior, such as replying to messages on OkCupid or Tinder, selecting a partner in speed dating events, or who people choose to dance with in couples dancing events, women behave differently from men.

The behavior of women generally follows the power law distribution, and the behavior of men follows the normal distribution.

This means that women rate the attractiveness of men based on something that is based on preferential attachment, for example how women believe others rate the attractiveness of the man, whereas men rate the attractiveness of the women on something that is independent of the evaluations of others.

When the pool of potential mates grows, the inequality experienced by most men grows, whereas the inequality experienced by most women stays the same. And the pool s growing due to internet dating.
Not true in Japan, Apple Pay uses anonymous ICOCA (aka Suica) cards which you can delete and recreate if you want.
Maybe! Could also be ST as in Sami Tikkanen, the author.

Edit: Ooh, looks like ST-DOS is this person's MS-DOS clone. Nifty!
Kinda related, it looks like there are a few new(ish?) "world building tools" for fiction authors now. Would be cool if authors started using these and made the databases available together with the works.

Many decision makers only talk to other decision makers across the corporate boundaries, so that the people nominally leading the software devs are never interacting with the people who actually use the software either, just the people who purchase the software.
I have a friend who was making ~300k at Blizzard (after being there for a while and a number of promotions) working on engines, and another who made quite a bit more then that working on an engine for CoD.

The thing is, he likely could have been making 30-50% more if he was working at a FAANG type company in terms of where he'd likely slot in level wise.
Looks pretty cool!!
> I couldn't understand how Apple Pay could work when my phone was in Airplane mode. But of course it does! Your existing Visa card works just fine without an internet connection.

If you set it as an express card, it also works if the phone is shut off or has a dead battery. (As long as it's not too dead.)
Ask HN: Mnemonic for shift() and unshift()?
JavaScript push() and pop() are intuitive method-names because they come from the context of using an array as a "stack". You can "push" things to a stack meaning a new item is added as the new last element of the array. push() pushes a new element into the array. Pop() pops one off it.

shift() and unshift() on the other hand I always had trouble with. One of them adds a new element to the front of the array and the other removes and returns the 1st element. But which is which? I can google the answer but would be nice if I didn't have to google. And worse, sometimes I got confused between the two and used shift() where unshift() should have been used => Error,, stack overflow!

So I googled for "Mnemonics for shift() and unshift()", and found an entry on Stack Overflow. But that question was "Closed because the answers are opinion-based". I looked at the answers available but none of them struck me as particularly memorable.

Now after years of struggling with this confusion I think I've come up with a mnemonic I can live with:

Word "shift" is shorter than the word "unshift". Therefore shift() makes the array shorter.

Word "unshift" is longer than the word "shift". Therefore unshift() makes the array longer.

I know it doesn't really explain it, but it is a rule I can remember. I would appreciate hearing how anybody else remembers when to use shift() and when to use unshift().
Huh? Free? A ton of tax money goes to both road maintenance and public transportation. This kind of price hiking comes off as a double-dip. Surely they have enough money in the budget already?
This is all fine for lower levels

More likely the other way round; if there are more options at lower levels - as you imply - then there are more ways for the principle to be countered or defeated.

None of this has anything to do with vision, ability, or merit.

Unfortunately, if you take the principle seriously, that's pretty much exactly what it has to do with.
"Compartmentalization of the work appeases the mind a lot."

Definitely. When I worked at a aerospace co some of the young engineers had internal conflicts they rationalized away by saying "we aren't building bombs." No, they were just building the targeting systems. Pointing the gun but someone else pulling the trigger. So it's all good.
Without a copy of the book, I don't remember which parts were based on Kahneman’s own work, and I don't see that we can/should just skip the other chapters.

R-index guys said [0]: "Table 1 shows the number of results that were available and the R-Index for chapters that mentioned empirical results."

Chapters where estimated R-index < 50: Ch 3,4,6,7,11,14,16

Chapters where estimated R-index > 50: Ch 5,8,9,12,17,24

Chapters that don't cite empirical results (by Kahneman, or who?): 1,2,10,13,15,18-23, all of 25-38

As to the chapters that had empirical results, and had an estimated R-index > 50: scores of 55, 57, 60, 62 are really scraping by; saying that means they "probably replicate" is setting the bar really low, even quoting Tversky and Kahneman (1971) back at themselves. (The R-index guys say "Even some of the studies with a high R-Index seem questionable with the hindsight of 2020.")

As to whether he was the one-eyed king of the replication crisis, he certainly started speaking out in 2012 [3] after the social priming scandal broke; did insiders have suspicions about non-replicability before that and should people have pushed back more, earlier? The fallout from the Francesca Gino and Ariely scandals continues.

Sounds great - I'm a huge fan of Georgia Tech's online masters.
As for AI, I think if it solves all your problems, great. And it's real-time, and free.

But! The reason I still work on explanations.app is that, I often struggle not with "facts" but with the "fundamental way of thinking". How do the great mathematicians think about matrices, do they just see them as numbers on grids, as vectors, as transformations, how do you you think in the first place, how do you approach the problem, that kind of stuff is what I struggle with the most. And that's very hard to articulate too as a specific query, which is why Youtubers like 3B1B are so amazing - there are so many hidden choices they had to make to frame their explanations in certain ways and in certain narratives.

Anyway you can always let me know if you want to try out explanations.app : ) best of luck
Actually the 7713 too (non-P, dual socket compatible) can be found for less than the 7C13, around $1500-1800:

Edit: from comparing https://www.servethehome.com/wp-content/uploads/2024/03/AMD-... and https://www.amd.com/en/products/cpu/amd-epyc-7713 it seems the only difference is the 7C13 has a Configurable TDP (cTDP, hence the "C" in product name) that is lower: 165-225W (7C13) vs 225-240W (7713). This would explain why the 7C13 is a tad more expensive than the 7713.
>To accept this view is to accept the idea that most of our ancestors had "childhood poverty trauma". I just don't see how it's a useful frame.

For most of the human population, this has genuinely been the case. Most of South/East Asian and African adults are barely 1-2 generations of separation from living in poverty. Most of them are very familiar with the struggle of giving kids a good life in much worse poverty than that experienced in much of the West, and would very much rather their grandkids not go through the same thing.
There's nothing "secret" about this.

Most countries with any tourism business (real or hoped-for) do this. Even Saudi Arabia.

> People made the same arguments about reusable rockets.

NASA could have totally gone forward with developing the DC-3 if Nixon didn't cut their funding. The lower cross-range and payload were dealbreakers for the USAF but perfectly acceptable for civil spaceflight purposes.
> My take though is that even if apple opens up the NFC chip, they aren't opening up the Secure Enclave. So even if a bank app can take over the NFC chip, they still will have secrets in memory at some point without a new P-256 based payment protocol.

The NFC chip is itself a secure enclave. (It's called a "secure element" but same thing.)

It does its own key storage, which is why it can work when the phone is turned off.
The problem is satellites take a long time to manufacture, upwards of 10 years, and everything is very mass optimized. The industry is too slowly adapting to cheaper more frequent launches.

> As a setuid program meant for elevating privileges, all code that is compiled into sudo-rs has the potential to accidentally (or intentionally) give access to system resources to people who should not have that access. The setuid context additionally puts some constraints on how code is executed, and dependencies might not have accounted for that context. We could not expect any of our dependencies to take into account such a context either.

This is the real problem. I've come to the conclusion that setuid programs basically shouldn't be using most libraries. The setuid environment is just fundamentally different. A normal library can have a debug output file who's location is controlled by an environment variable without that being a security risk. But the instant that program becomes setuid, that's an arbitrary file overwrite security bug. Most libraries aren't built with that in mind. They shouldn't have to be. Setuid is poorly designed.

Owning a bank is an extreme regulatory headache. You always want someone else to be the bank. Or even better multiple someone elses - in the US, small banks are allowed to do things large ones aren't, so you sometimes gather up a bunch of them and become a single proxy for them.

It’s not about payment of the $250 in rental fees. It’s about them giving you possession of their $25,000 asset.

And, “doesn’t have a credit card” is actually a pretty good proxy for either “not creditworthy” or “some kind of weirdo”, with neither of these being the people you want to let use your $25,000 car for $250”.

Agreed, there is no IP address to collect, so this part of the article is inaccurate.

The rest of the article is not necessarily scaremongering, but they don't explain the issue well: it's not just a "giant clicker" as described, because it collects personally identifiable information (cellphone MAC address) without permission. This would be illegal in many other countries.

Additionallu, they claim the data is "encrypted" but since it's not an open algorithm it's possible that it's flawed, either because it's deterministic or reversible.

Debit cards don't all have to be processed through credit card networks, it's easier to do it that way. Websites could also take direct bank transfer payments if they felt like it, but it would hard internationally.

There's also a lot of country specific debit/atm networks (including several in the US), if you are ok with debit over credit.

I don't think you've received a good reply to the congestion part of your comment.

The most poorly understood urban planning concept by the general public is the idea of induced demand. Usually this is applied to freeway expansion, which inevitably ends up being just as congested as pre expansion.

However, induced demand can just as easily be applied to parking lots. Especially in NYC area, very few people who drive and park don't have an alternative. Those people only have so much tolerance for looking for parking, so limiting parking will push people on the margin to transit.

For the individual, driving will almost always be the best choice if you build endless parking and highways. But, it's not necessarily better for the collective to allocate our land and resources like that. Parking lots aren't free. In fact, they require a huge amount of space. You can fit more people in an apartment building with that space!
