If I had a euro every time someone is skeptical of dark matter because they think it only predicts galaxy rotation curves, I’d have enough money for several beers (beer is expensive in Finland!) GRC observations were the original motivator for the DM hypothesis, but in the following decades its predictions (specifically, those of a specific cold dark matter model well-constrained by evidence) have been in entire agreement with many observations in several distinct subfields of astronomy, whereas no competing hypothesis has been able to achieve the same.

Indeed DM, or something very much like it, is a required ingredient in cosmology to get a universe even remotely similar to ours! As far as we know, we wouldn’t even have galaxies, much less the intricate foam-like structure of voids and filaments, without DM, and no competing hypothesis can predict the observed large-scale structure of the universe while also explaining galaxy rotation curves and everything else, for instance the Bullet Cluster, or the specific observed anisotropies in the cosmic microwave background.
"Probably the fundamental problem here was a sub-optimal schema, but sometimes you're just working with what you've got. Plus a commenter on Reddit pointed out that if we used pure SQL functions instead of PL/pgSQL, we'd also have seen better performance then."

So, would the better advice not have been to use simpler SQL instead of complex recursive statements, instead of taking a drastic approach to abandon ship (move logic to a completely new layer)?

Also, if you're doing string concats manually for your Json, this might cause some overhead for larger objects. ??

Clearly you haven't touched OpenGL. Nix apps on non-nixos need a wrapper to use OpenGL and what's worse is that you need a different wrapper for each GPU vendor
Judging by your comment history, you appear to live in the US.

As a brit who grew up during her time in power, I want to say the Thatcher was a vile, vindicive. and spiteful person who blighted countless lives in my country and community. Using her as an exemplar of morality is abhorrent.

"Works union" probably means he sometimes hires other people, and pays them union rates, and makes less as a result.

The market for fresh kidney bean leaves wouldn't be big enough to justify shops keeping them in stock, growing bean plants would take weeks and typically be impractical otherwise due to space and seasonality constraints, bean leaves dry out quickly so you would need a constant supply to fight an infestation, and given they are a discrete size and you have limited options for how and where place them versus a synthetic tape...
I am critical of AI replacing jobs that I believe are better done by humans but fear that economic pressure will net use the worse but immensely cheaper solution.

That said, imagine a justice system not barred behind immense costs. It is just as much a problem in free and open societies that legal rights cannot be enforced because it is just too expensive. Also legal abuse by the political or capital class where the process is the punishment.

Sure, some might be shocked that our rights might some day are laid into the hands of an AI. But it is worth a thought if the lowest form of sentient life is an AI or a lawyer.
It is pretty frightening how normalized this has become so that even organizations that should have the user's interests in mind won't even think before pulling this kind of shit.
I've long noticed that this idea - that scientists just "jumped to conclusion" that there must be some dark matter to resolve some observational inconsistencies - is very prevalent among non-specialists. It could not be further from the truth, of course - as soon as the rigorous statistical study of galaxy rotation curves was provided by Vera Rubin et. al. in the 80s, the MOND classes of alternatives to gravity started to appear.

I tried to understand why this narrative is so prevalent, and it looks like it is due to its very appealing nature - both to the listener and to the speaker: "all those egghead scientists can't see an obvious solution to a problem they are fighting with for decades". I also noticed that when you get deeper into it, then you find that the source - the "speaker" part in the whole narrative - is some kind of science popularizer. Who at the same time (surprise) is a proponent of his own flavor of modified gravity theory.

Truth is - everyone, including me, had this idea as soon as they first heard about the DM. If you actually study all the evidence and discussions around the subject, you'll see that introducing an extra "dark" particle is the most obvious solution to the whole collection of observational inconsistencies. Modifying gravity in such a way so that it is self-consistent and consistent with all the observations... I actually don't think anyone completely finished that project so far.
I’m about to start a new job, I’ve worked on and off at my current work place for about 13 years spread out over the last 20 years. We were an early start up and we did web development in c and then later c++ because the web browser and the database and web server and the os were all c/c++ so why wouldn’t we use it? We switched to c# and python and js/ts for new dev at some point because we couldn’t hire c++ devs at the same rates, that switch killed the company, but to us along time see it. Well the company’s not going to die, but it’s not going to be a software company anymore.

Our 20 year old c++ runs fine, and has been straight forward to extend.
Everything else got caught up in endless cycles of framework updates and paradigm shifts, leaving slag heaps of angular 1 and early dot net abandonware, years of work dumped because dependencies and frameworks were out of support.
It’s become such an unruly mess that if all goes to plan they’ll shut it all down, move on to a competitor technology, which I understand is all c++

Well, I was just trying to point out that median is a silly measure, but now we're really comparing apples to oranges. Every astronaut is not a NASA astronaut and so they haven't had to undergo a uniform skill test but there are still excellent odds that every astronaut is qualified for their role even if they are below the median "astronaut". Yes, it could be argued that every space agency has some sort of test, but the same could be argued of every employed dev as they'll have had to pass an interview.

Again, not saying that every dev is a good dev, but that median is a silly measure.
Any book can be read alone without a teacher.
That is actually an occasional problem for us because identifiers, including Enum values in Python (and probably some other languages) cannot start with a digit.
I don't think they have any illusions about it. They are enthusiasts and enthusiasts like to spend money on their hobbies. If they can afford it, I don't see the harm.
So is it better to not fund it?
“Because sciences tend to think of themselves as something as far away as possible from religion, as having freed themselves from God. To an extent that’s true. But in the process, they tend to generate these big stories, big mythologies, about the origins and the ends of the world. And conjure characters who are heroes, gods, and monsters. I started tracking the way that the natural sciences themselves generate new ways of understanding the world that, a couple centuries ago, we would have called religion.”

This aspect of the interview, to me, was far more interesting than anything to do with Elon Musk. I also was not aware that Nietzsche had called scientists "priests of the modern world." So it seems that even in the realm of space exploration--and I can hardly think of an area that seems to have been more insulated from religion--humans just don't seem to be able to help themselves but to keep reintroducing the religious and the supernatural (whether it be the Apollo 8 astronauts reading from Genesis or current NASA advisors checking to make sure they account for beings on other planets that might communicate through "shamanic states").
I mean we're trying to determine the mass of objects many light years away.

The concept that we might not be able to perceive everything isn't a real huge leap. Far shorter a leap than "everything we know about gravity is wrong".
Worth pointing out that elected officials have always been able to block incoming (paper) messages by noting the address and throwing them in the trash unread.

Someone pointed out that "blocking" tends to also imply preventing the blockee from seeing the blocker. Having this as the only option seems like a mistake in the design of a social media site.
> general relativity has had considerable predictive success, so replacing it with something else that works the same in some situations but differently in others seems more complicated than [...]

First: you're very correct - we shouldn't expect an easy solution.

Second: precisely the same argument applies to Newtonian gravity. It was phenomenally successful. The mismatch between observations and its model were more easily explained by lack in observations - and they were! We found Neptune because of that!

That role (of plugging holes in observations) is currently being played by dark matter. So chances for dark matter existing in some form are good from a historical perspective. On the other hand, from that same perspective, chances of gravity theory being slightly(1) updated for extreme cases are also good.

(1) "slightly" in the sense that the difference with the current theory, GR, would be nil or negligible in most cases.
> Oddly enough my friends are successful people. PhD holders, Business Owners, and people working in very respectable fields. I just wish I was a little like them, but alas.

IMO, it's a big advantage to be buying from a friend. When buying a site, it's hard to fully trust that some of the statistics like traffic figures aren't manipulated. In this case, you can probably have greater confidence that at least you're buying what you think you're buying.
I almost accidentally described woodworking as a hobby of mine recently; I realised just in time that I basically only (so far?) watch other people do it on Youtube. (Not counting fixing/altering things slightly in a more DIY/carpentry-at-a-push sense than woodworking/joinery.)
this seems practical advice that is simple to implement for a good night's sleep
You wonder based on what? Static will put something in the binary itself and it will be memory mapped in, which won't even need to be directly allocated.
On the flip side, often the acquihires are ways for VCs to get a soft landing for a company that isn't working and return a little capital. There are reasons that venture capitalists maintain close relationships with acquisition decision makers a big tech companies.

It depends.

Many people would call Amazon a tech company - but they employ a lot of customer service folks, warehouse workers, and delivery drivers. Most people would call Facebook a tech company - but they employ a lot of content moderators and ad sales people. And so on. Most people would call Apple a tech company - but they have people staffing their retail stores and repairing broken laptops. And so on.

Not every business can be run like Google, with zero customer support and zero service delivery :)
I've quite liked their mobile UX actually! On Android, I have an entire screen devoted to the widget. I swipe to the right, read the list, add to it, check things off. I rarely open the actual app.

core is part of the language (or at least, many parts of it are).

The way that rustc currently splits this up is an implementation detail of rustc, not something that must be copied exactly. Rust without core is not Rust. It's not even usable.
As with physical security, you often don't even need to attack the lock if you can instead compromise the latching mechanism.

Most local software cracking doesn't involve fixing the license key check or the crypto code at all. You just remove the conditional jump that exits the program if the check fails.

This is ancient knowledge and I would have agreed with you 15 years ago, today the only reason to not use an ORM is analytical queries.

Since the Postgres planner doesn't really allow you to tune your query there aren't many ways to construct your query in a way which would to a much worse execution plan. Over the years we have migrated most raw SQL back to using the ORM without taking performance hits, pretty much the only remaining raw queries are CTEs where we force a certain order of query execution.

Usually these ORM problems are caused by schema design anyways. If you need 10+ joins you are going to have a hard time with or without an ORM.
With the speed GPT4 is replying, you could easily move inference to GEO as well, and no-one would notice.
While you can create one on your own, any lib that doesn't have a tree widget isn't ready for primetime IMO. Obviously others may have a different opinion. Also, I don't believe there is any way to embed a webview at this point which is often necessary to embed things like charts or other widgets you don't want to create on your own.
That’s a good question. The type of guy I was referring to here would be all about custom building the entire thing - stringers, risers, treads, tailings, balusters, trim, etc. As far as I know, stairs are generally a custom thing since they have A LOT of code requirements and every space has different dimensions, unless you’re building track housing, etc.

There are a good deal of old homes that are worth good money and have owners with the means to replace or repair their old, squeaky stairs. Or renovations going on in old homes that require new stairs. And any new custom hone is going to need custom stairs.

No idea on liability insurance but I’d imagine similar to other trades. The stairs guy would only be responsible for gathering the space specs and design. They then build the stairs in their workshop and deliver them to the site. Carpenters install them. Then the stairs guy comes back and installs the railing, etc. which can take a lot of custom work (rail fittings, bending rains, etc) and balusters. Real craft stuff there.
> The reader will go through its standard business rules for floor limits, PINs etc and process the transaction.

Just on the limits part; here in Ireland (and probably a good chunk of Europe) the limit on a physical card is around EUR50. But on Apple Pay (and probably other phone-based card payments that I have tried) that limit is removed... I have bought TVs (EUR500+) and put a deposit on a car (EUR1000) with Apple Pay and no issues. Some terminals do have issues (older ones that the store just couldn't be arsed updating have a max 50 limit, even on Apple Pay) but most do not have this issue.

Long story boring; there must be something somewhere that tells it the limit is increased. Also, the reason is the security Apple Pay and others give. You will have a very hard time explaining how someone got passed your face id for a payment...

That's the point of the article. The idea of colonizing Mars has become a kind of religion.
Hey man I'm joking too! Relax friend. For all the differences, of course there are mostly similarities between Europe and USA. American culture is essentially today a blend of European and African culture, with the great innovation: the invention of the Great American Pastime, going to a nearby school and shooting children. Some of you American ultranationalists really need to learn to take a joke...

But for what it's worth, yes, Europe will never again be as influential as it was 150 years ago. But the US will never again be as influential as it was 30 years ago, or even five years ago, either. Plus ça change!
When I was younger, I was run over by a car. The stuff I had been carrying was left at the scene and later blown away (or picked up by a street sweeper). Back then, textbooks cost less than rent payments. But I did have to do that homework all over again.
YouTube is the platform most commonly used by teens, with 95% of those ages 13 to 17 saying they have ever used it, according to a Center survey conducted April 14-May 4, 2022, that asked about 10 online platforms. Two-thirds of teens report using TikTok, followed by roughly six-in-ten who say they use Instagram (62%) and Snapchat (59%). Much smaller shares of teens say they have ever used Twitter (23%), Twitch (20%), WhatsApp (17%), Reddit (14%) and Tumblr (5%).

I love how easy it is to create an account on youtube and turn the settings to allow over 18 content.

reminds me of the time a friend talked about how they had the wifi locked down and when the kid was an adult he said oh ya I used to just use the neighbors wifi
Currently only an optimised representation in a DB, but I guess they could be re-generated from that.
Instead of abandoning anything, why not just use appropriate tooling? Boilerplate if you want some code written for you, debugger if you want to know what's wrong with what you're doing. Been around for more than twenty years.
> Apple, Google, Microsoft - they all love to have someone else (i.e. venture capital) bear the cost of proving that a piece of technology actually will work out and is technically feasible, and then incorporate it into their product

It isn't just them. All large companies do this. They constantly watch the little players and anytime one of them does something interesting that seems like it is working they buy the company - this is in fact something venture capitalists count one: it is one of the easiest exist strategies they have.

Most big companies also play venture capitalists themselves: they are constantly looking for startups to invest in, with the idea that if that company produces something useful they will buy the company completely, if not they have carefully limited their losses.

Of course it is, because Republicans are overrepresented as a result of gerrymandering. It's also whiter, older, richer, more male, more straight/cis, etc., though this is less a Republican/gerrymandering problem and more a campaign finance/political culture problem.
that's a good problem to have, if you have bed bugs at all. Its like saying why would you have a crumpling car bumper that would be destroyed in a wreck and then he unsightly or need an expensive replacement.

I would happily have this stuff permanently painted on bed feet. If you have bed bugs to get attached id much rather have them impaled even if I had to refinish my beds legs (in reality you would just clean them off or replace the temporary flypaper)

I think egui is complete enough to use in real apps. Layout can be a bit weird, but I haven't found anything that's impossible.

I might even prefer it for cross-platform apps since startup time is so slow for GTK on Windows.
People sure put a lot of weight on an off-the-cuff comment Musk made in 2012, before Starship was even a gleam in his eye. That was the same year NASA published their SPS-ALPHA study[1] on modern SPS design, so Musk may not have been aware of it.

Modern designs use a phased-array transmitter, and a reference signal from the ground for targeting. Overall energy loss is 40 to 60% according to the book The Case for Space Solar Power.

Yup, that's what they do. Been there, sorry to hear.
Strangely I think we are fondamentaly in agreement. I think the spec is poorly written for the reasons you quote. I am not surprised to see people struggling with the implementation. It's not a good spec.
I used to spend money on apps, back when it was possible to buy them. Unfortunately, that's very rare these days.

I'm not paying exorbitant subscription fees for relatively trivial apps, let alone falling for the manipulative and often-basically-gambling nonsense of F2P games.

Apple are somewhat to blame for these trends though. Unlike 'real software for a real OS', mobile apps tend to need constant ongoing maintenance just to keep them working with OS updates and new devices. You can't just release a finished game/app and expect it to continue to be usable for decades, like the over-20-years-old Paint Shop Pro 7 that I still use almost daily on Windows.
The context here was that it’s not free, as I understood it. So, moving logic to the database, might make it faster, but that doesn’t mean that it’s instantaneous or that I no longer have to think about the scaling concerns of it.

So, personally, I read that section as “logic in the database is not a zero cost abstraction.

I've had this quote from George Orwell knocking around inside my head recently: "A man who gives a good account of himself is probably lying, since any life when viewed from the inside is simply a series of defeats."
I've noticed this effect when learning to play a game. In order to improve, one must practice a skill, but one cannot do so if they don't have an idea of what a better way to execute that skill is. Therefore, a certain amount of theorizing is required, otherwise one ends up just mindlessly playing and their skill stagnates.

This is part of why some people with 10 years of experience actually only have 1 year of experience, repeated 10 times.

The converse is also true of course, if all one does is theorize without practicing, then not only is the theory not being worked into a skill, but at some point the theorizing will be based only on prior theorizing instead of experience, which invariably results in incorrect theories.

The optimal loop seems to be:

1. Pick a desired skill to improve at

2. Analyze the way you're doing it right now and figure out a better way. This is the trickiest step, if unable to self-analyze look for guidance in others.

3. Consciously practice, one skill at a time

This applies to every skill in existence, not just games.
