I'm still in university, but I took discrete math at my university last semester and took data structures over the summer between semesters.

My data structures course mainly was graded from Zybooks assignments. I think it's actually a pretty good and understandable resource. It was this: https://www.zybooks.com/catalog/data-structures-essentials/

Anyway, maybe after you study discrete math from Coursera, that Zybook could help. It has some basics about big-O notation and determining the big-O of an algorithm (and calculating the number of operations it requires), but after that, it's all explanations of data structures accompanied by many animations and pictures. It may be tedious for someone who already knows how e.g. red black trees works, but it helped me understand them, as well as unbalanced BSTs, AVL trees, B-trees, heaps, and graphs. The stacks and queues were tedious for me, because I already know them.

I do think having taken discrete math helped me; I still flipped through CRLS during the course on the side, and their explanations were less impenetrable because I know the basics of mathematical proofs now.

There's also a book on data structures that went over hash functions (it's out of print, but I found a PDF online). It was also helpful for me. I'll reply to this comment with it when I get home.

It's an inflexibility. The other systems can use the blob or not. Nixos can only not.

Saying "well the blob sux anyway" is not much of a rebuttal even if it's true.
The temperature of a gas is proportional to the average kinetic energy of its particles. So if you compare (e.g.) water vapor to hydrogen at the same temperature, the hydrogen molecules are moving faster.

A hydrogen+oxygen chemical rocket propels H₂O, while a nuclear thermal rocket can use the lightest propellant (H₂) because the heat comes from elsewhere.

Smaller molecule, faster exhaust, better rocket.
that’s fascinating and to me, because as a vim user since 1998, I haven’t really consciously noticed it changing much.

If I tried running a version from 20+ years ago, today, would it still work on a modern O/S ? Are there modern vim features that I would miss?

i was _very_ surprised by that number as well. 10s for inference on 300 chars? using an entire A100 GB GPU? that does not make any sense. OpenAI and other companies would NEVER be able to scale to 100s of millions of users if that was the real number, right?
I guess we're not substantially in disagreement then.

Note that the Anti-Nazi laws in Germany were not -iirc- put in place by Germans, but in fact by Americans. In 1945 these laws made sense to deal with the situation at the time: in a society that had been severely distorted by NSDAP propaganda. As German society has changed, they make less sense now, and people have slowly come around to changing/removing these laws. I'm sure you can see why they are doing so very carefully. I understand the original reason for the laws, and I support the very careful removal/change of the laws.

In case you're curious (I was!): it is entirely possible to get a library loan for Mein Kampf in Germany. A quick google shows you might get a heavily annotated version printed by the state of Bavaria, but it's definitely available.

I agree with you on b). Nor do I disagree with democratic decision making by the community in general. I might have some opinions on people trying to subvert democratic systems to backdoor censorship and/or propaganda. (See also above, with that odd situation in Germany with quite a story to it.)

I think institutions in most western countries are -these days- quite well armored against incidental subversion. That's actually pretty good because that makes it easier to catch before things really go wrong. However, the laws, traditions and processes themselves only slow things down. You still need to actively catch people doing it and work to prevent it, so end of day you still need to maintain (eternal) vigilance.
> As Feynman put it, "Science is the belief in the ignorance of experts."

The lived experience of a recent Nobel prize winner is illustrative here.

> In April 1982, Shechtman spotted an odd atomic arrangement through his electron microscope at Johns Hopkins University: A crystal of aluminum and manganese arranged with pentagonal symmetry. It was thought to be impossible — five sides do not a perfectly repeatable structure make. The laws of nature held that the atoms in a solid could be arranged in an amorphous, blob-like pattern, or organized with symmetrical periodicity into crystals. Shechtman saw something that fit neither category.

https://www.popsci.com/science/article/2011-10/chemist-accus...

You would think a scientist holding physical proof from an electron microscope that atoms can arrange themselves in a way that had not been previously recognized would be able to share the discovery without being targeted by the "experts".

> He told his colleagues what he’d seen and they laughed him off, he said in an interview earlier this year. He was eventually asked to leave his research group for “bringing disgrace” to its members, he told the Ha’aretz in April.

Two years later, he finally published his findings, yet the skepticism remained — and it remained bitter, as the AFP explains it. The famous American chemist Linus Pauling once declared at a conference: “Danny Shechtman is talking nonsense. There is no such thing as quasicrystals, only quasi-scientists”.

https://www.popsci.com/science/article/2011-10/chemist-accus...

Nope. He was attacked by world famous scientific "experts" including a double Nobel laureate and fired from his job, despite presenting proof that what he was reporting was real.

It's the high temperature and the lower exhaust molecular weight.

Specific impulse (Isp) is how much force you get from each mass unit of propellant you exhaust. So an engine with Isp = 300 gives 300lbs force for every pound of exhaust gas mass.

IIRC, Isp scales as the inverse square root of exhaust molecular weight. So a pure (molecular) hydrogen exhaust would have a molecular weight of 2. A pure H2/O2 engine would have an exhaust of H2O (assume it's running at stochiometric H2/O2 ratio to simplify things), or an average molecular weight of 18.

For everything else being equal (temperature, pressure, etc.), the H2 Isp would be sqrt(18/2), about 3x the H2/O2 Isp. That's mainly why rocketeers would like nuclear engines, more oomf from a given mass of propellant. It's also (conceptually) simpler because you only need to handle one propellant vs. two or more for conventional liquid fuel combustion.

It's more complex, of course. If the reactor is really hot, it can partially dissociate H2 into atomic hydrogen, lowering the exhaust molecular weight still more. But dissociation is an energetically expensive process, so there's bound to be a tradeoff between energy consumed by dissociation vs. increased Isp. I've no clue how that would work out.
Some thoughts:

Science as it is taught, is about the conclusions that scientists have come to over the centuries, it's about how they made their observations and how smart they were. It is taught as an orthodoxy, a settled thing that you can trust. This does not reflect science as a current work product.

A related phenomenon is the math problem on social media - what is 2 + 2 * 3 (or similar). A complete answer is "Using PEMDAS, the answer is 2 + 6 = 8". But instead of giving the complete answer, which includes your assumptions, people fight about the answer. It's GREAT for engagement.

It's interesting to me that religion has evolved many times in many places. It must fulfil a human need. It would be a nice story to tell oneself that one has no need of a childish crutch from a bygone era. It's a much nicer story than realizing everyone needs crutches.

It takes an incredible amount of sheltered privilege to write of what I wrote as anecdotal.

But anything that doesn’t support the politically driven covid narrative is misinformation. I’m used to it by now.

Somebody I once asked me if I’ve been living under a rock when I raised similar concerns early on. Which makes me laugh… the people living under rocks are all the people who cannot see the damage their myopic fixation caused. Writing my concerns off as “anecdotal” just demonstrates my point.

What is the problem you're trying to solve? Is twitter... er... I mean X not unreliable enough for you?

Imagine someone depending on a resource that's on a device that moves in and out of service as you lose coverage or have to reboot to get bluetooth pairing to work right.

And what if you wanted to support TLS. Try explaining to normal people why they're getting security warnings because your CARRIER doesn't support dynamic DNS so your cert SN or SAN doesn't match your FQDN.

And proxies. I don't even want to think what carrier data teams will do to proxy requests.

I really like the idea of a carrier / manufacturer neutral protocol to get data (pictures, contact vCard, call logs, music, etc.) on and off a phone.

But it's not HTTP(S).

Aren't we talking about standardizing iterators? That makes the compiler slightly more complex, I guess, but for the language it makes it much easier to read and more approachable imo. That's the reason that range exists in the first place.

I don't see why the author's implimentation is so complicated. I really just want an interface that works with the range operator, and to call it a day.

type Iterable[T any] interface {
Next() (T, bool)
}

so that

for _, el := range someIterable {
}

is essentially the same as

for el, ok := someIterable.Next(); ok; el, ok := someIterable.Next() {
}

I certainly think the first is more clear btw.

It’s not that it’s impossible to parent without them, it’s just the easier path.

Parents, just like other people, will often take the easier path for a million different reasons.

> Funny though, kids seem to bitch less about masks and vaccines than adults.

That is only because they are too young to have the life experience required to call bullshit. And even if they could they have zero political power because they are kids.

And keep dreaming about how it caused no damage. We fucked over an entire generation of kids. It’s absolutely shameful what we did to kids. Adults sacrifice for their young. Not the other way around.

Good explanation! For completeness:

In an Ion jet, the energy comes from (usually) solar power and the gaseous fuel provides the bulk. These are even weaker because of the limited instantaneous power that can be generated to feed it, but they are very efficient in how much thrust they can provide per propellent weight. Some versions (like arcjet) are a combination chemical rocket/Ion jet.
We're past the transistor equivalent of AI (GPT-4), and into the logic gate era (functions/plugins). So it's a slow period until people build an AI layer on top of the application layer.

But computers tackled paperwork and calculations. AI tackles mental labor and attention, similar to how steam engines tackled physical work. They cover the only subset that had to be manually done by humans.

I expect the industrial revolution all over again. Higher productivity means the few will exploit the many. Some consider it unethical, maybe it is. But you can boycott unethical coffee. You can't boycott unethical guns.

The best example today is the writer's strike. We see it in art too, where companies using AI are boycotted. These sectors are likely to take a huge hit. Friends in digital art end up just changing careers - printing tshirts, becoming flight attendants and so on.

There's still a demand for these jobs, and the ones who get through the winter will be worth more.

The same goes for other professions. Those in the bottom will go first. Hiring will freeze. Those at the top will have enhanced productivity and earn more. A logo designer can brainstorm a hundred ideas in 15 mins with AI and then draw it nicely.

> If you can't distinguish between science, medicine, media and government policies, there's little we can do.

I surely can. And this thing you say has nothing to do with what I said, which is that they destroyed completely trust in all of those institutions.

I don't know what you're arguing for, all of those things you list happened because of the desire to ignore the actual science and common sense in favor of preferred policies.

1 They caused a panic

2 They didn't fight off the virus very well

3 There was unrest, there is still unrest, and to all those problems, add that people don't trust science, medicine, governments or media

4 The policies enacted kind of were a dead end? A waste of 2 years for little benefit?

5 There was none. No studies, no data, no previous experience.

6 It came out anyway and thanks to point 3, all the goodwill is gone.

I don't know, apply those standards to the course taken? What conclusion do you reach? That everything would be much worse otherwise?

So that's my point. The "clever" policies are going to fail anyway and now nobody trusts the people who pushed them.

It's not difficult: Don't lie. And whoever feels the need to censor people who disagree with them, well, I don't need to check if they're lying anymore.
>To describe it as "not a democracy anymore" is wildly sensational and inaccurate. (And I say that despite personally opposing the reforms for other reasons.)

On a technical level it's wildly sensational and inaccurate. On a political level it's what a lot of the supporters of the judicial reform bills have been saying.

The whole "Mac versus PC" thing somewhat solidified the notion that PC refers to x86. Raspberry Pi uses ARM.
These are all standard ARM instructions. Apple tweaks the semantics of some of them in Rosetta mode to better support what they’re doing but it’s otherwise not involving any new encodings.
I strongly disagree. I've recently contributed to a project that uses an email-based workflow, and find it considerably easier to use: after a surprisingly brief one-time setup, I can contribute patches using a single `git send-email` command from the same terminal that I make my commits, and can review and comment on patches from my email client of choice (thunderbird) – all without needing to create a new account.

Applying patches is, admittedly, a little more awkward, but it can still be done in two or three steps from thunderbird (including invoking `git am`) and, I understand, some newer email clients can handle this much much better.

> It makes vastly more sense to transmit a patch attached to the specific code base state that it is intended to modify:

This is no longer a problem. `git send-email` (and `git format-patch`, if you prefer to call it directly) has for a while supported a `--base=auto` or the `format.useAutoBase` configuration option to attach the upstream commit ID to the patch. To my knowledge this is currently only to help the maintainer understand its context but there is ongoing discussion of ways to automatically use this information.
> So IMHO, they are not giving more capacity, due that capacity is going to be consumed for to try to keep alive the data. If one fills the QLC disk of the article for long term storage, bad things will happen, as I understand it.

Your opinion aside, QLC drives really do offer more capacity for your dollar, and the extra write cycles necessary to stave off data degradation do not render the drives useless. You absolutely can fill a QLC drive and leave the data on there. You may need to perform scrubs a bit more often than you would for an equivalent TLC drive if you're not writing enough new data to keep things fresh, but that's hardly a showstopper.

> But what is happening, I think, is along years they are stretching like chewing gum the NAND incrementing the bits by cell, hopping the people adopt the reduced endurance as a normality at prices of data-stored, not of NAND chips-used

People have been predicting a catastrophe of low write endurance for many years, and it keeps not happening. There's some plausibility to the notion that consumers may end up getting screwed over by cheap drives that cannot hold up under reasonable usage, but consumer QLC drives have now been on the market for five years: the time limit on those drive warranties is now expiring, with no sign of an epidemic of premature drive failures. And in the enterprise SSD space, it is foolhardy to presume the big customers that would consider buying 256TB SSDs do not understand their workloads and endurance requirements well enough to correctly determine whether QLC is suitable for their needs.
Yes but I’m presuming the person I was responding to meant “role” in the context you’re talking about, but by “user” they meant a row in some “users” or “customers” table corresponding to their application. Questioning the need to “create role” for every application user.

> When discussing human rights

I've never heard an argument before that the ability to host a personal website on a cellphone is a human right. But, by using this phrase, you seem to be assuming your readers already agree with you that human rights is what we are discussing. As a rhetorical device, that may be effective at getting someone to back down for fear of being labeled as anti-human-rights, but it is not effective at persuading someone of your implied thesis. I'd very much like to hear such an argument connecting cellphone websites to human rights.

Your comment sounds to me like "I've won the lottery and I don't understand why everyone else hasn't".
