> Does "electrified" mean pulling power from a third rail?

Yes, or more precisely either third rail or using overhead lines (catenaries). Overhead lines have many benefits over third rail so they make up the majority of new electrification projects, but third rail still has a lot of use in suburban railways and metro systems.

> Whatever it means, what makes "electrified" twice as fast as diesel-electric?

You're completely right about the engineering, it's just that the diesel generators don't have quite as good peak power output compared to a fully electric system. I think that the article is overplaying this particular benefit of electrification though. The trains that I frequently take are bi-mode, and although you can certainly feel the extra 'kick' of acceleration when you enter the electrified parts of the line, it makes little difference to the total journey time compared to the old diesel-electric trains that used to run on the route.
Most of the railway trips people were taking would be fairly short distance trips you'd now hop in a car for, not a plane. Inter-urban transit, not trans-continental. You can look at old railway connectivity maps of the US to see the kind of station density available along the lines. This is why the size of the US continent is not a really good explanation. It's like saying "Europe is too big for trains, which is why nobody rides trains in the Netherlands". You don't take a plane from Amsterdam to Rotterdam, and you wouldn't have taken a plane to get from Boston to Providence either. Trains also can serve small towns that airplanes don't, because you don't stop a plane at every town along the way between city centers. In fact, many towns just sprang up around train stations.
People may be altruistic, but in a company setting they may have no possibility for altruism. CEO decisions influence property of others (the shareholders) so he can not freely pursue altruistic goals.

Because people keep repeating the urban myth of portable assembler and being the very first systems programming language.

One of the very first systems programming languages was JOVIAL, from 1958. C's inventors were still finalising their studies.

> Copilot can help me cook the equivalent of a McDonalds special in terms of software. It's good, I think McDonalds is delicious.

No. The likes of Copilot help you cook the meal you'd like, how you'd like it. In some cases it forgets to crack open eggs, in other cases it cooks a meal far better than whatever you'd be able to pull together in your home kitchen. And does it in seconds.

The "does it in seconds" is the key factor. Everyone heard of the "million monkeys with a typewriter" theorem. The likes of Copilot is like that, but it takes queues and gathers context and is supervised by you. The likes of Copilot is more in line with a lazy intern that you need to hand-hold to get them to finish their assignment. And with enough feedback and retries, it does finish the assignment. With flying colors.
Super read! Thanks for sharing
You were always free to buy fewer things you care more about.
I enjoy the cheap shipping (from Aliexpress China warehouses to Germany), but I really wish this would be improved. It just seems nonsensical. There should be a closer relation to actual cost, but paying 4-5€ for a national shipment, versus essentially nothing for Chinese shipments, is mad.
That's a great question.

I was concerned about this, so I provide the following two APIs:

* https://docs.gamesbymason.com/zcs/#zcs.Entities.chunkIterato...

* https://docs.gamesbymason.com/zcs/#zcs.Entities.forEachChunk

Both of these iterate over chunks instead of entities, and as a result the iterator only needs to advance once per chunk of contiguous entities. The caller is then responsible for calling chunk.view (https://docs.gamesbymason.com/zcs/#zcs.chunk.Chunk.view) to get slices of components from the current chunk, and from there they can either rely on autovectorization or implement the vectorization themselves since they're now working actual slices of data instead of an iterator.

I haven't actually checked if the optimizer is smart enough to work back from the higher level API and realize that it's just an abstracted for loop. I inline some stuff to encourage this, but my assumption is basically that this is an unrealistic thing to expect it to do hence the lower level API. Providing the per-chunk API also isn't really a maintenance burden or anything since the high level API is implemented in terms of it anyway.

There's an argument to be made that I should only provide the lower level API since it's likely more optimal, but IMO it's less friendly & switching to it in the rare instances where it turns out to be a bottleneck should be easy enough.

Is my chunk iterator API similar to where you ended up with, or did you take it a different direction? Feel free to link your project if you want, I'm always interested to see how other people handle this stuff!
This "AGI" definition is extremely loose depending on who you talk to. Ask "what does AGI mean to you" and sometimes the answer is:

1. Millions of layoffs across industries due to AI with some form of questionable UBI (not sure if this works)

2. 100BN in profits. (Microsoft / OpenAI definition)

3. Abundance in slopware. (VC's definition)

4. Raise more money to reach AGI / ASI.

5. Any job that a human can do which is economically significant.

6. Safe AI (Researchers definition).

7. All the above that AI could possibly do better.

I am sure there must be a industry aligned and concrete definition that everyone can agree on rather the goal post moving definitions.
Australia has a slowish rail network because it is sparsely populated. It is an extreme version of America, the distances between population centers are quite large and there's not much in-between. There's also not much reason for anyone from Sydney to visit Canberra, and if you do, you certainly need a car to get around.

Big part of coding is understanding the code and making decisions on what needs to be added/removed/changed. LLMs can code, even if they generate perfect code every single time, someone still needs to read the code and make decisions. Others speak about understanding business logic, interfacing with clients and stakeholders,etc... I get that, but even without that, someone will always need to decide how things should be done, improved,etc.. LLMs are not going to benchmark your code and they will never understand the developer/client's intent perfectly.

Why are LLMs in these context being viewed as more than really powerful auto-complete/intellisense? I mean, correct me if I'm wrong, but aren't LLMs still years away from auto-generating a complete complex codebase that works without fixing a lot of bugs/assumptions?
Nice! This is a much-needed space for security tooling, and I appreciate that you've put some thought into the new attack vectors. I also like the combination of signature-based analysis, and having an LLM do its own deep dive.

I expect a lot of people to refine the tool as they use it; one big challenge in maintaining the project is going to be incorporating pull requests that improve the prompt in different directions.

This is my experience with AI bots. This is my robots.txt:

User-agent: *
Crawl-Delay: 20

Clear enough. Google, Bing and others respect the limits, and while about half my traffic are bots, they never DoS the site.

When a very well known AI bot crawled my site in august, they fired up everything: fail2ban put them temporarily in jail multiple times, the nginx request limit per ip was serving 426 and 444 to more than half their requests (but they kept hammering the same Urls), and some human users contacted me complaining about the site going 503. I had to block the bot IPs at the firewall. They ignore (if they even read) the robots.txt.
A lot of comments mention it has been a thing in various forms through the internet’s brief history. The interesting question is why didn’t it take off—especially when the technology was there.

One possibility as you allude to is licensing. In a P2P streaming model “rights” holders want to collect royalties on content distribution. I’m not sure of a way you could make this feel legal short of abolishing copyright, but if you could build a way to fairly collect royalties, I wonder if you’d make inroads with enforcers. But overall that problem seems to have been solved with ads and subscription fees.

Another data point is that the behemoths decided to serve content digitally. Netflix and Spotify showed up. The reason the general population torrented music is because other than a CD changer, having a digital library was a requirement in order to listen to big playlists of songs on your… Zune. Or iPod. That problem doesn't exist anymore and so the demand dried up. There was also an audiophile scene but afaik with Apple Lossless the demand there has diminished too.

And finally, since people were solving the problem for real, we also entertained big deal solutions to reduce the strain on the network. If you stream P2P your packets take the slow lane. Netflix and other content providers build out hardware colocated with last mile ISPs so that content distribution can happen even more efficiently than in a P2P model.

In short: steaming turned into a real “industry”. Innovators and capitalists threw lots of time and money at the problem. Streaming platforms emerged, for better and for worse. And here we are today, on the cusp of repeating the past because short sighted business mongers have balkanized access with exclusive content libraries for the user numbers.
Certainly. If you look at the various steps in cellular respiration (happens in animals, starts with glucose and ends up with ATP) you'll see that it takes many of them to gradually release that energy such that it can be made use of at a rate that jives with the cell's needs. There's so much complexity that has gone into controlling this rate. It would've been much simpler to just burn it all at once and explode.
You might, but consumers of FOSS code are extremely unreasonable.

After some experience, starting to use a new programming language is not such a big challenge. Mastering the new language eco system is. AI might help you generate new code faster, but feel like crunching code has not been so much of an issue. Bigger picture system design, something that scales and is maintainable is the challenge.

> No, copilot is not endlessly variable. It works best with typed languages and an enterprise mindset.

I don't think your assumption is true. The key factor is the corpus used to train it, and the context you fed it. I already experienced Copilot fumbling references to methods of a simple Java class, whereas it pulled off thinks like ARM templates flawlessly. You need to understand that internally LLMs do probability-based text completion. If you feed them enough context to maximize the probability they output things you expect, they do so.

Mahdawi allegedly supports Hamas. Hamas is officially designated as a Foreign Terrorist Organization (FTO) by the State Departmemt. This designation means that providing material support to Hamas is a federal crime under US law. Green card holders or anyone in the US can face serious legal and immigration consequences for any form of support or affiliation with Hamas.
I'm sure you know this, but to clarify for those that don't, it goes way deeper than the volume published as The Silmarillion. In The History of Middle Earth, Christopher pulled together all / most of the drafts and published those, along with notes and commentary that relate them to each other and try to put them into their linear and creative context. It got up to I think fourteen volumes, and there's probably no more-complete record of a great artist's life-long creative process. It is, as you say, a truly monumental work.

That's perfectly fine, because that's what you expect from human work to begin with. From natural text like blog article or tecnical reports to software changes, all output is expected to comply with patterns we are already familiar with. Heck, look at pull requests, where you ask your audience to evaluate your work hoping to reach a consensus.

That's an incorrect version of Zionist history which in the 19th century until the British left were more concerned with legally buying land, and many were trying to coexist with the Palestinians.

Also, the Hebron community that was massacred and ethnically cleansed in 1929 predated both Zionism and the Arab colonization which brought most Palestinians to the area

Also right after being against attacking civilians, you are saying that's actually alright because they had had done that as a reaction. That logic applies to anything in the conflict, including the civilian dead the Palestinians are now suffering after the massacre/kidnapping they have conducted. That's why I think you should rethink that line of thinking

As far as I know, the way it works is shipping companies can do the % package value (ad valorem duty) or the flat rate per package (specific duty) but have to do the same method for all packages and can only change their method once a month.[1]

My speculation is the ad valorem duty requires more manpower to implement and so that's why there's the specific duty option. Especially because they originally temporarily halted the de minimis changes due to USPS not being able to handle it.

I beg to differ. What makes me an investor is buying a share of future company profits, directly via dividends or indirectly via a future sale of shares. Many of the companies I invested in over the last 30 years were (over time) reducing share counts via buybacks, not issuing shares like candy.
