I don't have a CS background and when I eventually had to do interviews for Google, "Calculate mean/median/mode of temperatures" was the interview question I went with, intending to avoid BS leetcode*

I always worried it was too easy, but I'm heartened by how many comments miss the insight I always looked for and you named: you don't need to store a single thing.

I do wonder if it'll work here, at least as simply as the tracking vars you mention, with so many rows, and the implicit spirit of "you should be able to handle _all_ data", overflow might become a legitimate concern - ex. we might not be able to track mean as simply as maintaining sum + count vars.

I ignored fountain pens for a long time because I'm not a calligrapher or artist and I mostly want writing to be easy and convenient.

On a whim, I finally ordered a LAMY Safari and was really surprised at how much better the writing experience was. I noticed my penmanship improved and I was able to write more easily on parts of the page that I normally struggle with, such as near the binding in some notebooks.

I attribute most of this to how easily the ink flows compared to other types of pens, although I'm sure the pen shape is also a factor.

Anyway, if you write a lot and just want to write more easily and a little better, I'd recommend giving a fountain pen a try, and I think the LAMY Safari is a great place to start (it is relatively cheap and the cartridges are convenient).

I also love JetPens and order most of my pens and stationary from them.

Arthur Whitney is a mad genius. We were an early customer of KX systems and I programmed with KDB for a few years. Arthur Whitney once sat at my desk and helped me debug my code. Very nice guy. Super smart and hilariously knowledgeable about the low level performance of chips, caches, etc. Ask him how many nanoseconds it takes to divide an array of doubles by an array of ints, and he knows. He just knows.

You think satellites are cheaper than ground towers?

Even if they were cheaper, a satellite is limited to 7Mbits/s. A 5G tower can handle 10Gbits/s. And you don't even have to price a cell tower by the kilogram.

Sounds like you figured out the solution on your own.
The title is a lot more exciting than what is actually being claimed. They say that malfunctioning mitochondria are to blame ... but there is no insight into why the mitochondria are malfunctioning.

My wife, a formerly energetic, outgoing, type A person, has been suffering from ME/CFS for 20 years. Long COVID symptoms are highly similar to ME/CFS problems, and the hope has been that the long-underfunded ME/CFS research would benefit from the research money that has come with COVID. Thus, I felt let down when I read the linked blurb.
The cost center vs. profit center concept has some utility for accounting, but overall it makes more sense to model the business as a modular system seeking a global optimum, a la Goldratt, rather than a set of separate sub-organizations each to be optimized separately.

In other words the business as a whole should be viewed as a singular profit center, and each department or project should be evaluated in terms of how much it contributes to optimizing the overall performance.

> if an employee undermined leadership's authority, it is likely that they won't last long.

It is hilarious that you (and many other people in this thread, it seems) would consider this letter "undermining leadership's authority". If someone's authority is undermined by a letter like this, they are not much of a leader.

I have worked at companies led by other zillionaires you may have heard of, and seen letters circulate and questions asked live in an all-hands meeting that went much farther than this letter. Those employees got good faith answers to their questions, and still work there. Now that's leadership.

Interesting. For another data point, it turned a "normally" 12 hour trip into about 13.5 for me. (Sacramento to Seattle)
I think our best bet would be tape.

Currently tape is amazing technology for archiving data and long term storage.
The pysical media costs very little...the big cost is in the hardware for reading and writing.

I really wish we had an alternative open hardware competitor to the current tape market. I could justify the cost of tape but even used a lto7 library or a single reader for a desktop can run from a few grand for parts all the way up to 8 grand from what iv seen.

YMMV

I'm surprised there's a market for budget foutain pens. We mostly don't write by hand anymore and if we do, it's to jolt down notes.

One chooses to use a fountain pen for the thrill of it, or for love of tradition. In those cases, money is no object. A budget fountain pen is like a budget race car.

Obviously I'm wrong, but I'm not sure why.
Twenty years ago this paper was considered surprising and, together with a handful of other attacks and with the concrete attacks against MD5 and SHA-1 succeeded by some Chinese researchers prompted the organization of the SHA-3 competition.

John Kelsey and Bruce Schneier:
"Second Preimages on n-bit Hash Functions for Much Less than 2^n Work"

https://eprint.iacr.org/2004/304

The abstract at this link provides the essential results.

"We provide a second preimage attack on all n-bit iterated hash functions with Damgaard-Merkle strengthening and n-bit intermediate states, allowing a second preimage to be found for a 2^k-message-block message with about k * 2^(n/2+1) + 2^(n-k+1) work. Using SHA-1 as an example, our attack can find a second preimage for a 2^60 byte message in 2^106 work, rather than the previously expected 2^160 work."

Besides this result, there is also the previous result obtained by Joux for multi-collisions, which also become easier for longer input data (Antoine Joux: "Multicollisions in Iterated Hash Functions. Application to Cascaded Constructions").
1. https://en.wikipedia.org/wiki/CAP_theorem

It feels the CAP theorem was more talked-about in the years of NoSQL frenzy. It is of course still highly relevant. Despite being widely known and discussed, I think it fits the "non-intuitive" description because most people really want systems to have all three (consistency, availability and partition tolerance).

2. Buridan’s Principle ( http://lamport.azurewebsites.net/pubs/buridan.pdf ) - A discrete decision based upon an input having a continuous range of values cannot be made within a bounded length of time.

This is more of a "philosophical" principle, but if you read the paper it does have practical implications.
Yeah, the people acting like carshares and rentals are low-friction feel like they live in a different universe than the one I lived for over a decade.

Open the app. Oh no, the car that's near my apartment isn't available when I need it. Ok what else is around? Ehhh the BMW is pretty expensive and unnecessary. Ah here's a Honda... but it's a 25 minute walk away.

Ok so I have to walk 25 minutes just to start the car. Then I can go where I want to - but if I bring anything back I'll have to find street parking in front of my apartment building to unload. Then I have to bring the car back to its spot, and then walk another 25 minutes back home.

Oh and don't forget to gas it up, because unlike owning a car, with a carshare more often than not you have to gas it up on the way back to avoid a penalty. You roll your eyes slightly at not just having to drop by the gas station but literally paying for the rental time to do it. But it's fine, whatever.

Like, I get that lots of people find this to be fine (I did, for over a decade!) - but it's anything but low-friction.

Traditional rentals are even worse - unlike carshares their pickup/dropoff locations are nowhere near you, so now you have to think about an Uber!

Summary
With recent findings connecting the Epstein-Barr virus to an increased risk of multiple sclerosis and growing concerns regarding the neurological impact of the coronavirus pandemic, we examined potential links between viral exposures and neurodegenerative disease risk. Using time series data from FinnGen for discovery and cross-sectional data from the UK Biobank for replication, we identified 45 viral exposures significantly associated with increased risk of neurodegenerative disease and replicated 22 of these associations. The largest effect association was between viral encephalitis exposure and Alzheimer’s disease. Influenza with pneumonia was significantly associated with five of the six neurodegenerative diseases studied. We also replicated the Epstein-Barr/multiple sclerosis association. Some of these exposures were associated with an increased risk of neurodegeneration up to 15 years after infection. As vaccines are currently available for some of the associated viruses, vaccination may be a way to reduce some risk of neurodegenerative disease.

One of the bizarre anachronisms I learned about from the coverage of this is that the Post Office was able to perform "private prosecutions" [1] bringing criminal proceedings without involving a public prosecutor.

> No, we are not prepared to let you make decisions for us ("But many in that group will be served fine with alternatives"). No, that's precisely the problem - Centralised planning thinks that the alternatives are fine, and they are often not. Similar to Google not having a phone number to unblock locked accounts.

You're making a jump here that is not at all warranted.

Many literally means many.

Not in the sense that they will get lucky, but in the sense that different people have different edge cases.

They're not trying to tell people what their needs are, it's that different people truly do have different needs.

A bunch of people are arguing that their purchases have to cater for needs that they don't actually have. Trying to argue them down is not trying to say nobody has those needs, it's that too many people are thinking about a problem for 5 seconds, not considering alternatives, and claiming to have needs, when the actual number is a lot smaller.

It's not about specific people being told they're wrong. It's statistical. We can count how many people are doing X or Y and it's not most people. People get aspirational about the future and make claims that are wrong. Or they consider a lack of an "expected" feature to be far more impactful than it actually is. It's not uncharitable to say this about statistical aggregates, it's a fact.
> If you live somewhere where electric costs are very low then a 0 to full charge your EV costs about $10.

I rented a Tesla Model 3 recently. From 40% to 98% cost me $7 CAD and I was able to drive from Vancouver to Tacoma, WA on a single charge and arrived with 20% battery. In the Seattle suburbs it cost a bit more, $13 USD, to go from 20% to 90% due to a supercharger station having issues so demand was higher at the next closest one.

$7 to go 175mi(283km) sold me on an EV as my next car. I never felt like I would be stranded and when the battery is conditioned for fast charging by time you pop in somewhere to use the bathroom and grab a coffee or snacks you're pretty much good to go.

> Isn't this simply bound by the speed of the disk?

Depends on the OS and filesystem being used. The input file is ~12GB, and it's being run 5 times on a machine with 32GB, so after the first run the file could be cached entirely in memory. For example, Linux using ext2 would probably cache the entire file after the first run, but using ZFS it probably would not.
Maintenance is a bad word for it, but the author clearly intends it to be in that category:
