The reason for this, as I understand it, is that it's super easy to make a lightbulb that lasts 30 years. But there are two main trade-offs that make it bad for consumers:

1. Stronger filaments that last longer will be a lot less efficient, so the consumer ends up using a lot more electricity.

2. The filament doesn't burn per-say, but actually evaporates. This is why it'll eventually break. But where does the evaporated metal go? It condenses on the inner surface of the glass, making the lightbulb dimmer than when it was new.

So 1000 hours is a good middle ground. The lightbulb is fairly efficient and 1000 hours isn't long enough for the inside of the glass to get too dark from the condensed filament metal.

Price of the bulbs was also reasonably low. It's cheaper to change out a lightbulb every 1000 hours than the electricity costs of a 10 000 hour lightbulb that emits the same amount of visible light. I don't have hard numbers for that, but it's my understanding.

Watch the youtube video linked by one of the grandparent comments. It's super informative and also contains some experiments to show the trade-offs.

Joe Armstrongs dissertation is also an enlightening read;

The article only compares idle power as far as power consumption goes, but regarding compute performance compares the systems under full load. This is somewhat of an apples-and-oranges scenario. If you care about the compute performance under full load, you should think about performance-per-watt, not about idle consumption. And in that capacity, the RPi 5 will easily beat any enterprise surplus mini PC with a 10-year-old architecture.

One of the mini PCs tested in the article has a CPU with a 65W TDP! That's considerably more than the Pi 5 will draw (the entire SBC's power supply only has a capacity of 25W).
Instead of monthly listeners & who the artist is similar to, I'd recommend searching by the genre each artist belongs to primarily & their current geographical region of residence.

Monthly listeners on Spotify is generally a heavily manipulated number, even for pop artists, that has no bearing on artist skill nor collaboration worthiness.

You can also perhaps base artist finds by comparing who they follow compared to who the searching artist follows, which might be a better indication of compatibility than "Sounds like Drake".

Then I'd recommend a better method of getting in contact with that artist (email address) if they are supposed to be a collaborator, and possibly displaying information about their web site or IG bio text and th4e last post by each searched artist.

Oh that is a vice you will find frequently here - reacting but not expressing, condemning but nor orienting...
And the public static void main and then endless conversations about packages, and public/private fields, that will backfire very pragmatically (at the time) unit test frameworks didn't have a way to call private methods ... Ironically by the time you're done with the basics, nobody has stamina anymore to learn anonymous inner classes.

The thing is, somehow syntax and some forms of abstractions cast a magic spell on most of the population (at time myself included) .. it's your mental interface to the semantics, so you want more syntax to be able to have more abilities, but syntax composes badly.

At least to me that's why I enjoyed lisps / lambda calc, it reduces the domain into a more homogeneous space, suddenly more things are possible with less. Although it seems that the mainstream rather enjoys doing simple thing with verbose tools (it does looks like you're doing a lot of work with a lot of advanced terminology) than solving hard problems with APL oneliners (hyperbole).

Some programmers have serious math envy. This can be good if they are self aware about it and keep it in check, because it makes them better programmers. Otherwise they can a pain to work with.

Somewhere I ran across the idea that programs should distinguish between errors and apologies in their messaging.

An error indicates the user's fault: they need to correct their input before retrying.

An apology indicates the program's fault: either logic for what had been incorrectly thought to be a rare^2 case is missing, or the program has only been configured to deal with N foos, and the user's input requires more. In the former case, the user needs to get a programmer fix before retrying, but in the latter, maybe they can just reconfigure and rebuild (even better, restart with different env vars?) then retry.

The relevant point of this is that when the user is likely to be another programmer, "reconfigure" can be as simple as editing a static allocation.
> It’s awesome that they have the flexibility to choose different launch partners and can use the most reliable and flight proven technology.

Does Starlink not have that option? Do you think other launch providers would refuse to take SpaceX's money?

Also this isn't a situation where you need reliable and proven. If option A has 99.9% reliability and costs $80M to launch $20M of satellites, and option B has 95% reliability but costs $60M to launch $20M of satellites, then you should go with option B for your fleet.

I thought Swift compiles to machine code? Can't it eliminate the unused stdlib code?

Well, I guess not if the statically linked binaries are so large, but this seems like the more major reason for these very large binaries instead of stdlib being monolithic? (Not entirely sure what that means in this context)
It does, but there’s a get-out - meta just say that they don’t operate in Portugal, even though they do sell to Portugal, and therefore there’s nobody to claim against. I’d have to go to a higher court, and again, the calculus here is that it’s not worth the consumer’s time - I don’t want to spend years and thousands of euro fighting over it - so the quest just went in the trash, and I’ll never buy anything from them again.

Trading crypto requires complete trust in unregulated exchanges who set and manipulate prices. Even p2p trades are based on prices set by these exchanges.

Most exchanges create their own "stable coins". These unaudited and unverified coins can easily be used to manipulate the market. In the real world, this is called "fraud".

>>Arguing that your 'champion' has ALWAYS been a liar — that argument does not mean what you think it means

He's not my champion. I generally like him, but disagree with him on some issues. I defend anyone against clearly agenda-driven attacks, whether I support them or not.

>>90% of the news media, including 'local' media, is owned and run by only SIX corporations.

Is that why the media conspired to hide the Hunter Biden laptop story during the elections?

The corporations cannot override their unionized employees, because of labor laws and collective bargaining agreements.

And the corporations themselves are often dependent on the labyrinth of regulatory restrictions inhibiting competition, and government contracts, for their bottom line, so are by no means biased toward political parties that defend free market principles.

>>Right, so all people are mere sheep being "taken in" by the evil news media, except for you...

I think the people who have turned on Musk have been taken in, and I haven't. Naturally I think I'm right. Now what I think doesn't matter. What does is the evidence I provide, like the coincidence of public opinion and news media coverage turning against Musk precisely when he began vocally criticizing positions espoused by the political left, like advocating censorship of views critical of tbe Democratic party, and minority viewpoints on COVID and gender pronoun use, on the largest social media sites.

>>The fact is that your hero, who we agree always lied, initially delivered some really great advances, and initially had the reputation of an engineering wizard, has in more recent years failed to deliver on decades-old 'promises',

Tesla hit sales records precisely before and during the period when the mainstream/establishment turned on him. Tesla became the most successful US automaker in a generation, and for a time, was the most valuable automaker in the world. And all while building only fully electric vehicles.

SpaceX made enormous strides in reusable rockets, with record numbers of launches of Falcon 9, and significant advances on its fully reusable Starship space vehicle, in exactly the same period when you are claiming he was falling short.

Look at this graph of number of space launches per year:

https://ourworldindata.org/grapher/yearly-number-of-objects-...

The massive increase in US launches was solely due to SpaceX. To put it another way: the US restoring its leadership in the pivotally important space industry was entirely due to Musk's company.

Sp no, your arguments don't stand to reason. His behavior and performance would not explain a significant portion of the population turning against him.

The establishment, which includes all the left wing news guilds which dominate news media, turning against him for his anti-establishment comments, would.
Further proof that Python is not fit for functional programming and that Python's namespaces and default lookup by reference are confusing.

In terms of the risk of a “malicious chip”, that has nothing to do with the display or USB-C. Any cable could have a malicious chip in it at this point.

> CTB: one surprising commonality amongst many of the interviews thus far is the lack of use (or disdain for) debuggers. Almost everyone trots out print statements!

Interesting. I came of age before debuggers were a 'thing' available to common kids at home (80s BASIC, etc). As I've worked in various environments over the years, debuggers are nice when available, but they're not always available. Code is only running in production, you don't have full access to a debuggable environment, company won't pay for tool X, etc. print/log statements always work, regardless of what tool/language you're working with. Or... 'always work' enough of the time that it's not surprising it's a common theme.

I jump between client projects relatively often (consulting) and while I do use debuggers, I don't use them exclusively (perhaps no one does?). The longer I'm in a codebase, the more likely it will be that I'll end up with a full debugger setup and get comfortable stepping through all the bits.
Overlap is coincidental, yes people may be doing similar kinds of things in a game. But Microsoft flight ‘simulator’ doesn’t come with a bunch of built in systems for handling loss of hydraulic pressure the way actual training systems do. The general public doesn’t want to spend time memorizing checklists for minor systems issues etc.

The other kind of simulation where people are trying to understand how systems interact is even further removed in how they are used. Running the exact same hour plus simulation repeatedly while only changing initial conditions isn’t fun, but it can be informative.

Nice comparison! Worth noting that pg_cron is available on almost all managed PostgreSQL services. Also, many thanks to Devrim Gunduz and Christoph Berg for providing community packages.

I wrote pg_cron with the intention of keeping it as simple, reliable, and low maintenance as possible, so it's likely to remain that way.

It is possible to implement a more advanced job schedulers on top of pg_cron if needed. For instance, you can set up a few parallel jobs that run every N seconds and take an item from a job queue table.

This sounds like classic corporate bamboozlery. Find some real trade off that actually exists and then exaggerate its importance or pretend that no other solutions can be found when in fact they don't want solutions because the problem is profitable.

Undoubtedly there are some alternate materials you could make a light bulb out of that present a trade off between longevity and efficiency. But there will also be materials that last a long time and have high efficiency. Moreover, even if they want to use the filament material that emits whiter light and then burns up faster, they could then use more of it so it still doesn't burn out quickly. But they don't want to do that, because it would cost marginally more and more importantly then you wouldn't have to buy as many light bulbs.

It's no good to pretend this isn't possible. There isn't an inherent trade off between brightness and efficiency, because inefficiency is just the percentage of the electricity that goes to producing heat rather than light. At the same power consumption, a more efficient bulb is brighter. LEDs are rated as "100W equivalent" even though they consume ~20W. And the LEDs themselves last far longer than the equivalent incandescent light, but then they purposely combine them with a power converter that burns out much sooner. It's marketing, not physics.

Reddit is so hard for newcomers
How do you gain karma on Reddit when you constantly get blocked and filtered?

I am a cybersecurity expert and I have experience in writing decent technical content (like https://blog.vidocsecurity.com/blog/hacking-swagger-ui-from-xss-to-account-takeovers/ or https://www.moczadlo.com/2024/delightful-inputs-with-intellisense-and-syntax-highlighting)

It is almost impossible to translate it into Reddit karma - I tried posting content on some of the subreddits, but I simply can't cause of minimal karma requirements.

Reddit said that you need to comment before being allowed to post content on most of the subreddits, but for me, it is really hard to find interesting posts I could comment on.

It is far easier to create new engaging content, than finding ways of contributing to existing content. You need to filter through hundreds of bad posts to find a couple of interesting ones and be early enough to add value through comments.

How do you do it?

That book was my first programming class and programming ever: CS61A at Berkeley. When I started taking it, one of the TAs said that the ideas in the class were wasted on us - they seemed simple but we wouldn't grasp the fullness of the ideas until we had more experience. He said the class should be required to take twice: your first and last class.

It gives you basics of things like recursion and message passing that are easy to use immediately (well, once you figure them out -- it took me two weeks to be able to write even the simplest recursive function), but there are large conceptual things you won't really see the depth in until you have more experience. The last project is the meta-circular evaluator - writing a scheme program to interpret scheme programs. It is difficult to understand that without having a lot of other background.

Even then along the way learning things like exceptions as implemented through call/cc might be a little too much for a beginner programming. The book is in some ways talks about concepts way outside of a beginner's comfort zone.
