It's true. Fun and relevant fact: The job title data scientist was invented at LinkedIn when they saw data analysts that needed to know R or Python skills. These skills seemed different enough from the traditional Excel and SAS data analyst jobs at the time to warrant a new job title.

So did Excel not cut it, or was it a preference to use Python? Back then Excel supported up to 65,535 rows, and would typically crash with over 8,000 rows. I worked in that era in Excel. One model once was split across three spreadsheets. Only one spreadsheet could be open at a time, they would take 20 minutes each to load, and there was about a 50% chance they would crash while loading.

So what do you do if you need over 65,000 instances of labeled data? For a neural network it's nice to have a million instances, yes a million.

R and Python have in them what is called a dataframe. It's a spreadsheet, but in another programming language. We tend to load our data into those, which is just like Excel, but without the hardware limitations. So in many ways, today it's just like it once was, but we get to choose which programming language to use while working in a spreadsheet, and let's be fair, the Excel programming language isn't exactly great.
Flash loans let anyone borrow a large amount of crypto with no collateral, provided the loan amount plus a fee is returned in the same transaction it is borrowed in. No collateral is required because there is no risk (assuming no exploits).

This means you can't take the highly speculative trade, you can only go for a sure thing. But if you do have a sure thing, you can borrow as much currency as the lender can provide.

The thing that makes me the most crazy about the internet is the number of people who pay an excessive amount of attention to me and remember ridiculous stuff about things I said years ago or whatever and are just wrapped around the axle about how I am not entitled to my stupid opinion or something.

And I just always feel like "If you think I'm so dumb or something, why in the hell do you clearly and obviously invest so very much of your time, effort and memory in tracking details about me and my life? Good lord."

I think you're very _very_ wrong about people ops at Apple.

The reason why Apple in 20 years turned from being 90 days away from bankruptcy to a revolutionary machine and most valuable 2+ trillion dollar company in the world is not because of HW ops or anything else, it's because of people.

While we know Steve Jobs had "issues with people", he also clearly stated:

> My model for business is The Beatles. They were four guys who kept each other kind of negative tendencies in check. They balanced each other and the total was greater than the sum of the parts. That's how I see business: great things in business are never done by one person, they're done by a team of people.

It takes a lot of people effort, talent and operations to achieve what Apple has achieved. So I think saying Apple is mediocre at people ops is unfair.

There's also the highly secretive internal Apple University for employees - https://www.nytimes.com/2014/08/11/technology/-inside-apples...
I don't know. Procedural and declarative languages can both query and manipulate data. Maybe I'm being pedantic, but that's not my intent.

For all of SQL's warts, it is the golden standard, and I agree with most everything else you say (it's succinct, easy to get optimal behavior, etc.) but compared to what you can express with Spark in Scala, it's not the end-all-be-all of expressivity.

In fact, several SQL-compatible query engines have extended SQL to allow you to do work around its limitations and manually hint at what you want the engine to do. And even then, there are tons of situations where you fight the engine to do what you want.

If I had a nickle for every Data Scientist or Finance person I unblocked because what ends up being a recursive join was making their query run time infinite...
You make good points, but I think you should revisit your assumptions.

Fission is so expensive mainly because of safety and regulatory concerns: radioactivity scares people, and so safety requirements are cranked up to 11: everything is overdesigned just so that current regulator is confident enough (next one might one up anyway), lots and lots of concrete and steel is used for containment etc. Additionally, the whole construction process is hopelessly bureaucratic and takes forever, requiring inspections of inspections, redesigns for things that in, say, coal plants would just be redone differently by contractor on site and so on. We most definitely could make fission significantly cheaper, and in fact it has been so in the past.

Now, fusion does not have similar safety requirements. If the plant blows up for some reason, there's no significant radionuclide contamination. Therefore, there's little reason to require safety standards significantly higher than those for coal plants (the boilers of which can also catastrophically blow up). This makes it significantly cheaper, due to reduced material use and construction time/labor for containment, and reduced regulatory delays.

Your point about power density is also good, but I don't think it matters very much in practice. Sure, fusion reactor might have significantly lower power density than fission reactor, but so what? Renewable plants are even worse when it comes to power density, yet it doesn't stop them from being rolled out. We don't lack space for fusion plants, even if they are much larger than equivalent fission ones.

“Just because other people don't understand you doesn't mean you are correct.”

True. Also true that it doesn’t mean you aren’t. Though it does at minimum strongly suggest that your attempts to explain yourself to others have thus far sucked.

Bitcoin isn't valuable because of its technical properties, just like gold isn't valuable because of its physical properties.

Both are valuable because of their universally recognized scarcity and value. If you want to put your wealth in a SoV cryptocurrency, Bitcoin is the clear schelling point.

Ether will remain competitive with BTC, it may even flip it in market cap, but I doubt Bitcoin will ever go away.

I don't buy that, liability to who? If Netflix goes down, I'm gonna cry and tweet about it, I'm not going to cancel my account. Their catalog is unmatched. colocating across the world is not easy, they also have scale that goes up and down based on time of day, and say holidays where they really need to scale up. Cloud is great for that, the elastic part is great, place the core on there and scale up and down as needed. What they did with active-active resiliency and being able to shift traffic across regions is the entire point of cloud, as we some a bunch of services where down last week with AWS having issue but netflix never skips a beat on such issues.
Sorry if I came across as a little aggro--I'm definitely projecting the typical anti-Mac person onto you. It's generally step one of the hate on the MacBook playbook. "Psssht if you buy a MacBook you're living the dongle life."

And it's just not been the case for me with the recent MacBook Pros. Like your experience, with past laptops I've used I've always had to carry around different adapters, regardless of whether the machine was Windows or Mac. No matter how many ports the vendor tries to shoe-horn into the laptop, they can never quite get them all in there, and so you end up with a dongle or series of dongles.

With the MacBook implementation of USB-C, I carry one small USB-C hub that gives me pretty much everything from ethernet to microSD. The infamous "dongle book pro" actually has made my life less dongle-y.

And that's where I see the whole "bag of dongles" as a disingenuous line of attack from people who don't actually use the machines for their real lives. In practice, it's the least dongle-y laptop I've ever used.

(thanks for coming to my ted talk)
> Yeah, no shit, it's hard to get things like referential integrity and transactions working at scale, it takes many genius engineers and many years.

Well, the problem is that such mechanisms _must_ be in place (in well-designed applications); they're not optional.

The consequence is that, if they're not implemented at the lower (db) layer, then they're going to be implemented at the higher (app) layer.

There is often the discussion of indexing/referential integrity for schemaless data stores. One may think that such data stores solve those problems; they don't - they push it to the application.

Therefore, it takes many genius engineers-years... anyway. Solutions provided by the data stores, like FKs, just happen to solve the problem out of the box (where applicable, which of course, it's not always the case).

The article actually mentions this, although not so dramatically :-)
I'm in my 50s, have three now-adult kids. The toddler years have some nice memories to be sure, but do I "miss" them? No. Would I want to go through that again? Also no. Same for all the other ages, newborn, toddler, elementary school, puberty, high school. It was all great, but no interest in a rerun.
Why would mining be anything but selfish? The only reason miners are operating is because they expect a reward that is greater than their expenses.

That means block rewards plus TX fees need to be greater than the cost of running the network. Block rewards are effectively a tax on existing holders through inflation of supply, but that will go to zero in the long run. As the rewards decreases, TX fees will need to increase, which means the average TX will rise. This will increasingly make using BTC prohibitively expensive unless the block size is increased so as to allow more TX per block.

But if the scenario should arise where revenue no longer covers the costs of being a miner, the whole economic model breaks down. This could even get to the point where going rogue, and attempting to exploit the network with the hash power, could become more profitable for a miner.

Yes, but that doesn’t really make sense for things they have already shipped: researchers have to reverse engineer those for what seems like no reason. For example, the newest iPhones have entirely custom privilege levels that are lateral to the typical ARM exception levels and entered using proprietary instructions that their own silicon understands. This is something you can find if you load the kernel into a disassembler and poke at it a bit. But Apple doesn’t mention it at all or document it…what’s the point? Why put up such petty barriers in the face of people trying to audit this?

Stable ABIs don't seem like a good solution though. It is preferable that the system running the code should make
the decisions on how best execute it. Especially as hardware becomes more specialized and diverse. Additionally,
guarantees of stability necessarily increase maintenance burdens, so they should be avoided whenever possible.

IMO, the best solution would be something like SPIR-V. That is, programs are shipped in an intermediate
representation which a platform-specific compiler would reduce to the final program. That way no stable ABI is
needed, there is less maintenance for distros and toolchains, and end users still get high quality binaries.

Of course there are issues with protecting the intermediate representations of programs from reverse engineering.
But the combination of strong DRM with obfuscation should satisfy most software vendors. After all, most companies
are comfortable shipping Java based programs.

The code I'm talking about needs to run fast (or be type safe) or you wouldn't consider using Rust. But internally in a library or a function that gets ran over and over again and needs to run super fast often isn't a lot of lines of code. So what I mean by a researcher may not even write a function is, they write the meat of the algorithm, it gets handed off to software engineers, and they turn it into a library or OOP it or whatever, and then run it on servers.

My current project in Python is massive compared to a normal one atm and it's about 2-3 pages of code in Jupyter. In Rust, if the libraries are there, it would be about the same size. I have 8 functions atm. It's also the end of the project and I'm in talks with data engineers to wrap it in OOP. They'll handle the IO. Or at least, that's how I've always done it and I've done a project in Rust.
This is an excellent point, and I’ve been on the other side of it. Just like you said, you end up not wanting to comment on anything because you’ll end up getting it as a gift.

Have you used Gchat for bots/search/threading? It’s awful. It is not a good chat app and hasn’t changed much in 4 years. It plays catchup with competitors. Teams is so far away from having good features and app integration; Everyone I talk to that used Slack hates it. It’s just that it’s free with o365 that it’s even used. Honestly, I want to remind people everyone said the same thing about Google buying YouTube and FB buying insta. Two large purchases that were so worth it for the companies.

Well, it'd stop the vandalism and town theft, the originally defined issue: Free publicity that leads to sign posts being stolen. For a tiny village of 100 people, this is likely a serious hardship.

But more notably, it's a way of moving the problem into a more concretely defined space, ideally out of sight and out of mind (and the money is just a bonus). Such a shop would become like the tourist portion of any large city -- a place locals avoid, and captures most of the visting rabble.

You'll still have your vandals and troublemakers on the street, but hopefully at significantly reduced rates.

I'd suggest giving Eufy 2k cameras a try. I was also a long time Wyze fan but I've recently switched to Eufy after trying out their 2k cameras. Compared to Wyze, it offers better resolution (thus 2k in their name), on-device pet/human detection (Wyze charges monthly fees for cloud-based detection), and way better app experience. It's slightly more expensive but well worth the price for me.
