> Single node application systems are by far the most reliable and manageable from a business logic standpoint.

Manageable? Maybe. Reliable? No. Most companies don't need it but if a pipe bursts above the server room and now all of your medical records for your hospital are unavailable you're going to have a bad time.

> At no point does spreading a problem across more than 1 computer make that problem easier to solve.

I don't think anyone claimed it was easier (yet). The main thing people strive for is:

1. Dynamically reshaping your compute needs to match any needs.

2. Surviving failures of nodes or crashes in your application.

3. Managing all of the BS that goes with obtaining this (logs, etc).

> Especially considering the fact that I have still never had to do this exercise in a production setting. The hardware we run this stuff on is so ridiculously stable.

Keep in mind, it's a federal crime to melt any 5-cent or 1-cent US coins for the purposes of selling the underlying metal, punishable by a $10,000 fine and 5 years in prison. c.f. 31 CFR § 82.1 (https://www.law.cornell.edu/cfr/text/31/82.1)
"dog" being the parent of "ant" in the original string-based binary search tree is just an accident.

Consider the characters. Is the "g" character in "dog" the parent of the "a" in "ant"? We can "explode" the original tree like this:

[ L | R | S ]
/ \
[L | R | S ] [0] -> 'd'
\ [1] -> 'o'
"ant" [2] -> 'g'
[3] -> 0 // null-terminated C string :)

Now we have an anonymous node which is has two links to other nodes, and a link to a string. So it is the parent of the string and of the two nodes.

What the binary search tree is doing is representing the sequence { "ant", "dog", "fly" }. It captures that this sequence has three elements, which are in that order.

The fact that "dog" is a parent of "ant" is not relevant in a search tree; it's just an artifact of how the tree is balanced. In the following tree, it is a child of "ant", yet it is an equivalent search tree:

ant
\
dog
\
fly

The bitwise tree, a kind of radix tree, does the same thing: it stores "ant", "dog" and "fly", indicating their presence and order in the most detailed way possible: by switching left/right on their individual bits.

To clarify, I know you may not have said "no one can" but plenty of other HN commenters are saying exactly that on a regular basis. Thank you for refraining from repeating this absurd hyperbole.

C programs are not inherently smaller and faster but in practice this is usually the case. Can you guide me to some Rust programs that are smaller than their C counterparts. The thing that holds me back from experimenting more with Rust is the (apparently) enormous size of the development environment relative to a GCC toolchain.

The number of downlaods from crates.io is questionably large and some of the binaries I have produced were absolutely gigantic. Largest executables I have ever compiled. Crazy.

We do not "lose" if people keep writing in C as long as its the right people. The right programmer for the job. All programmers are not created equal no matter what languages they use. Absent professional certifications and enforceable quality standards, perhaps the world of writing software for use by others needs an ethos something along the lines of "code within your means". Memory-safe languages are great but it seems like they just enable people to become far too ambitious in what they think they can take on. This is no problem at all unless and until they start marketing their grand creation to undiscerning users who are none the wiser. (This is of course the general idea behind the "dont roll your own" meme. However, I do not think it should be limited to cryptography.)

> Unrelated but related: How do we keep stories like this in the "middle" of our minds? I've noticed with myself--and many others--that we read articles and essays like this, contemplate them for a moment or two, think about how we should be more {appreciate, grateful, thankful} for what we have, but then--inevitably--somebody cuts you off in traffic, or the plumber is late, or your coworker does something annoying, and just like that, everything comes flooding in.

Our habits seem to me to be like those of creatures who anticipate living forever, but don't really know what to do with all the time. It's interesting that suffering—not so much success—is what keeps this in our minds. A sibling remarked on Dostoevsky and Solzhenitsyn, both men of profound sorrows.

You are free to voice your opinion. Society is free to provide feedback to you on those opinions. If you have an opinion that a sufficient cohort of your peers in society feel is out of bounds for where society is headed or not compatible with the prevailing world view, society will provide corrective consequences/accountability. The system is working as it should.

Anyone have any good examples of where something like this might be used?
Licenses are a major PITA when you want to be spinning machines up and down all the time. Some enterprise vendors have pay as you go solutions, but many don’t.

I get the impression that some enterprise vendors don’t offer pay as you go solutions because it would put their sales staff out of work, and because they wouldn’t be able to use a “how much can you afford?” pricing model.
It’s truly a singularly unique and poorly understood organ which also is the only known organ trying to understand itself - which is my point. Saying ‘it’s just an organ’ dismisses and minimizes all the important parts.

And the brain, just like many processors CAN and does work around damaged memory, and can and does work around damaged processors/bugs (depending on the nature and severity of them of course). Phineas Gage being one of the clearest recent examples, but there are many more.

Minimizing what is going on to saying ‘it’s all chemical processes’ is really missing the point - it would be like saying a modern CPU is ‘just moving electrons around’. It’s reductio ad absurdum.

I haven’t personally run across a Buddhist philosophy claiming knowledge of the way the brain works. I have run across Buddhist philosophy claiming to know how the universe works, which seemed pretty silly to me. I’ve also run across Buddhist philosophy aiming to provide tools to help people better understand and connect with it and themselves better, which I personally have found helpful.

You're not rambling, you're just living your life aloud.

What you have described is simply life, life at it's best.

How do we behave better? It's pretty simple, alas simple doesn't mean that it's easy. Here we go:

1. realize that we are indeed powerful, and we can stop things from degenerating.

2. Forget meditating, too short and restrictive practice. Practice "mindfulness". We can all practice mindfulness 24/7; my mantra is simple: "One, Two, Three, Four" over an over, counting my breath, or counting seconds, or counting my steps (Kinhin). Do it long enough and when life throws you a curve ball (someone cuts you off, plumber is late...) it's almost automatic that after a few minutes (or seconds for those more advanced, but not me) 1,2,3,4 comes to mind; 1,2,3,4, come back to the present moment.

While #2 seems elaborate, #1 is actually the most important one, realizing that we indeed can do something. It got me out of decades of depression.

Also, related, probably not applicable to you, but it was applicable to me: I read an article linked here on HN or "stop being a victim", the implication there is #1 above.

YMMV

Thank for you at least giving slightly more concrete examples.

There are a lot of semantic gymnastics going on in that blog post, specifically around identity groups:

- how lockdown/virus/vaccine skeptics _are_ an identity group,

- how lockdown rules and vaccine requirements are repression against those identity groups,

- how fascism is repression of identity groups,

- therefore a lot of people and governments are fascist now.

I think we'd both agree that it's wildly unjust that actual human beings have far fewer freedoms (a major one being freedom of movement) compared to corporations or their capital, so I can sympathize with the notion that more restrictions on biological beings is unfortunate, to say the least. But like in chess, we must play the board as it is, not as we wish it to be, and we're responsible for the predictable (especially policy) consequences of our actions.

The author is also a lockdown skeptic:

> Leading up to a (ritualised) date that announces a review of restrictions, the government generates terror on a mass scale – through its new gargantuan propaganda machine.

> The evidence mainly consisted of Sweden, Florida and other places that actually exist in the real world, and also the fact that the lockdowns haven’t worked

AND a virus skeptic:

> Imaginary variants, case numbers, double mutants (the possibilities are endless)"

And hence presumably a vaccine skeptic. These are further critical failures of analysis to add to that of "what constitutes an identity group and fascism".

Honestly, the _blog post_ itself almost reads like a psyop, but probably it's just the kind of nonsense that people like George Galloway and Aimee Terese are known for. Maybe if these failures weren't so central and didn't compound on each other, there'd be something else useful to say having read it.

Castle Rock was 7-2 and indeed was unanimous on the question at issue as a federal matter.

From Justice Stevens' dissent: "It is perfectly clear, on the one hand, that neither the Federal Constitution itself, nor any federal statute, granted respondent or her children any individual entitlement to police protection."

The basis for the dissent was that Justices Stevens and Ginsburg believed, out of deference to federalism, that the Supreme Court should not have ruled on the issue of whether state law provided for such a right, but instead should have deferred to the federal district court or certified the question to the state Supreme Court.

Moreover, the Constitution is emphatically not "a bit of old parchment." For shame.

For context, the original quote was:

* > How about understand the OS internals? How about write a compiler? How about write a library for their fav language? How about actually troubleshoot a misbehaving nix process?

Writing a compiler, writing a library for their fav language, and troubleshoot a misbehaving nix process are all examples of things I would definitely expect a CS major to have done at some point.

A SoTA compiler for Rust or whatever? Ok, no. But, you know, a compiler.

Ditto for library -- better than the standard lib? Ok, no. But, you know, a standard lib that's good enough.

ditto for debugging nix processes. Not world-class hacker, just, you know, capable of debugging a process.

I guess the other examples in that quote seem to suggest that "OS internals" probably means something like "knowledge at the level of a typical good OS course".

And who knows what those people meant by "comfortable interacting with operating systems in any depth". There could also be some reverse D-K effect going on here... "I got a B- in CMU's OS course" still puts you very well into the category of "understand the OS internals", IMO.

For someone buying ETF's monthly or something similar this is mostly correct. Your 100 share order is unlikely to move the market, and the time you spent trying to passively set up the order, and then babysit it is unlikely to be worth the time investment.

In crypto markets the difference between maker and taker fees can sometimes make it worth waiting, but you need to keep in mind that every minute you spend not having made the trade, is price risk that you are exposed to. And saving 5bps on fees might lead to you losing 50bps in price movement.
> Windows NT was "far better" than both, but was out of reach of consumer system for years...

Microsoft had a far better developer roadmap with "32 bit protected mode with just a recompile." They sandwiched OS/2 v2/3 from the bottom and top. When memory prices dropped, the period when OS/2 had a significant hardware cost advantage over NT was rather short.

I see this as Resume Driven Development. Yak shaving is fun and at some point complex DevOps becomes necessary, but most CRUD apps benefit from a simple approach that allows high feature velocity. It's a balancing act between productivity and technical debt.

> somebody cuts you off in traffic, or the plumber is late, or your coworker does something annoying, and just like that, everything comes flooding in.

I heard Sam Harris talk about this, and his advice was something to the tune of: Think about something terrible that didn't happen to you today. You weren't diagnosed with cancer. Your spouse didn't drain yoru bank account and leave you. Your child wasn't murdered. There are myriad wholly life-altering things that could have happened to you but didn't -- and even if you do have a bad day, it can always be worse.

It's admittedly a sort of pessimistic/dark way to look at things, but if you think about how it could be worse, it seems easier to look at the guy that cut you off in traffic and go, "Well, at least I wasn't just run off the road into the ditch."

Imagine a world where instead of saying "hey, people in your town are dying on the streets, your water is full of lead, you can't afford medical treatment, and your children can't possibly afford college, but quit being jealous of lucky rich people! It's not fair to them", we instead said "we could take just a little bit of unfairly acquired cash from mega billionaires and make the lives of 300 million people measurably better."

That lucky, smart, hard working, genetically gifted, handsome, strong, virile, well-endowed, wrinkle-free, and blessed by all the gods billionaire would still be able to go to space and give mindblowing amounts of cash to anyone they want even with 1/10th the wealth they have now.

Otherwise, society is going to reach a breaking point as it always has and will again. But that's just life.

If I were to build a rdbms today, and not for OLAP but OLTP, is this a good combination? I have imagine building my relational language about this stuff, and have wondered if building a paged "columnar" layout could be the best:

DeletedBitArray(00100100...)

col2 = "hello" "cruel" "world"

Page2(SizeOfBlock) =
col1 = 1, 2, 3,
col2 = "hello" "cruel" "world"

So this flip the rows into columns but for a smallish batch. Probably making locks expensive but never have implemented this stuff.
