If you already know the basics of what an OS does, it's best to just get into some more detail of how it does it. "The Design and Implementation of the FreeBSD operating system" is a great book for the structure of a *nix system. If you understand the design of one of these systems, none of the others is hard to figure out.

Beyond that, if you want a more academic read it's good to read up on some other architectures. This paper on the history of the L4 microkernel family is a really good discussion of the design decisions and evolution of that system that gets into some classic OS issues: https://trustworthy.systems/publications/nicta_full_text/898...

Other kernel designs worthy of interest are exokernels and unikernels. Also with regard to systems design I've always liked "end-to-end arguments to system design" (https://web.mit.edu/Saltzer/www/publications/endtoend/endtoe...) and another paper on the duality of OS structures (http://occs.oberlin.edu/~ctaylor/classes/341F2012/lauer78.pd...)

And yet you are unable to say what or offer relevant examples. Do you login in to websites using the key on your phone's SIM or your credit card? Both of those are amusing because they're bot not only irrelevant to the scenario in question but also something people use because that's what they were given, not something they sought out.

> And, probably not closely related to stack graph, but about using tree-sitter for c/c++ understanding, how to handle the preprocessor?

Ha yeah that's a good question. Some uses of the preprocessor won't be problematic ­— it would require deep token mangling, for instance, to really start to cause a problem. You can treat more basic `#ifdef` style conditional compilation as parsing/analyzing both sides and showing both as potential definitions. (And from there you could extend it further to try to identify (or define) "profiles" that have different preprocessor symbols defined, and use that to actually prune some of the results.)
What does 'faith' in clandestine services mean? The CIA is so powerful (above the law) and secretive that we just have to trust them? With a undisclosed black budget of $50B? more?

My fav. Milton Friedman often use to say that "Democracy is not about winning 51% of votes, it is about finding 5% of people who say they will vote for you if you take up their pet issue and they do not care how you vote on other issues. Then you selected another 5% of people with some other pet issue and so on. Together it should come to 51%".

What you are describing however is the opposite of this. People do not care how horrible a policy being proposed is, if it does not impact them or their loved ones. The conservatives who are flying "thin blue line" are the same people who are claiming that Jan 6 capitol riots were actually orchestrated by FBI and other branches of law enforcements. Conservative love for cops is not based on principles but it is more of a trick to "own the libs". Sooner or later the cops are going to come for the conservatives, for example Biden sending FBI after parents of schoolchildren will eventually be a template for states and cities to target conservatives of different stripes and you will quickly see those "thin blue line" flags going down.

Note how people who smoke marijuana are "addicts" and "junkies" who should be thrown in a pit as per many conservatives even though most of these "junkies" are productive members of society. But when it comes to opioid crisis they claim it is a "health crisis" for which "big pharma" must be held accountable. No one calls the addicts "junkies" or insists they should be sent to jail even though some of them are addicted to a point where they simply can not function normally.

Counterpoint: citations are a valuable currency in science. Arguably one of the best ways to earn citations is to do good work and write clear papers.

Not saying incentives are perfectly aligned -- many citations are superficial ("this topic was studied before"), and papers count for a lot even if they're never cited, etc
That's such a simple notion yet I was in my 30's when I read an article (wish I could find it but it wasn't necessarily unique) that basically said "the most fundamental definition of conservative is desire to keep status quo; the most fundamental definition of progressive is to change status quo". This goes a long way to explain both the motivations and the behaviour, but also why/how many seemingly disparate groups come together under these large Right/Conservative/Republican vs Left/Liberal/Democrat banners.

It also explained to me why in most countries I've been to, the "Right" comes together and unites whereas "Left/Liberals/Progressives" have multitude of semi-in-fighting parties: "Stay the same" is more universal than "Change!" (change to what ? )
I think it is an "AND" vs. "OR" thing. Your examples are great for those use cases, but there are others where having the long form is really good.

Cool, now you're just denying reality, the activities of those harassers towards them and other people are public record, so I rest my case.
Tobacco does have medicinal properties. For example, many psychiatric patients smoke a lot [0]. I propose they use nicotine to counter-act some of the terrible drugs they're forced to take.

[0] https://slatestarcodex.com/2016/01/11/schizophrenia-no-smoki...

Nicotene is a partial substitute for Niacin (Vitamin B-3). Niacinamide sometimes helps people reduce their tobacco intake.

The first generation anti-depressants were the Mono Amine Oxidase Inhibitors (MAOIs). Tobacco has MAOI-like effects too.

I think tobacco is also an anti-estrogen... Aromatase inhibitor: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2904480/

Compulsions have to be considered in context: people get benefits from tobacco that they do actually need. My friend (a misdiagnosed 'psych patient') took up smoking when she was 12, probably because she was depressed.

I can't recommend How to Design Programs (HtDP) enough.

The authors care deeply about not just the content, but the learning process itself. It may at times feel repetitious and even boring, but it's a principled introduction to CS which will set you up for success in ANY programming language. And the book is free online :)

https://htdp.org/

From here you can graduate to lower level programming concepts in C (or Rust), more practical languages like Ruby, Python or even Java for high level application design. Basically, it's time to learn about full-fledged memory management one way or another. Don't miss out on some type theory along the way, remembering that they are just codified data definitions and function signatures.
I would agree that the images are rather intriguing, but ... what does all this visual structure actually mean?

I would like to see how this kind of immigration is defined. I once worked for a company that was founded and went through the startup phase outside of the US.

Once it was somewhat mature and had a steady income stream the CEO moved to the US and put the new head office there.

This was because the US was the biggest market and it was vital to be close to the biggest customers.

Would this CEO count as an immigrant who started a profitable business in the US?
> And how to prune and simplify CST to AST at scale (supporting many languages)?

We're not doing any pruning or CST→AST translation, we just operate directly on the CST. With the new graph DSL you should be able to implement something like that, since an AST is a tree, and a tree is one shape of graph that you could create. For our purposes, that isn't a meaningfully useful step, since we can just as easily generate the stack graph structures that we need directly from the CST we get from the tree-sitter grammar.

Also, I believe there is a hierarchy that goes something like: academic papers -> review articles -> specialized books -> text books.

The text changes to fit the audience, and the knowledge becomes more accepted (and or fundamental) further down the line.

That's going to be a long read. Looking forward to it.

I'm old enough to remember the Japanese Fifth Generation Computer Project that went all in on parallel logic programming. Now, as the abstract of this article points out, we have "ubiquitous multi-core and highly-connected architectures", has its time finally come?

I would be very interested to read the opinions of some knowledgeable people here (triska?) about how well placed some existing software is, e.g swipl, mercury, and friends, to take advantage of it.
This isn't true. Once you know cars enough, the same thing applies to car repair.

Scammers moving in on new, powerful technologies is a function of regulartory arbitrage in the face of moving the massive boat of government. To get rid of the scam requires removing the arbitrage. Financial systems are centralized specifically because you can't regulate them without the rule of law. The IRS in the US has already required reporting crypto-asset income. All that is left is for government to ban transfers to/from anonymous wallets.
A systemic bank collapsing means that the companies who use them for paying their employees and suppliers, well, don't. This causes a chain reaction as the companies with a solid business model aren't able to execute it because they can't pay for their inputs (or their B2B customer can't pay for their deliveries) as their liquid cash is frozen until insolvency may return part of it, and they have to suspend operations, which is yet another hit on people (not) receiving salaries and on all the other related companies.

Protection of systemic banks is not about investors and loans, it's about the liquidity/working capital of companies and the people's salaries.

I think people are just bored.

Compared to the 2000s and 2010s it seems like there is less innovation. Much more significant, we have smartphones and technology which deliver fast dopamine and make everything easy.

People are getting ADHD-like symptoms and becoming desensitized to everything. They want novelty and intense stimulation. Events like the Capitol Insurrection, GME / cryptocurrency “lottery”, off-the-rails politicians - those provide novelty and intense stimulation. A global apocalypse or war, even though it would be awful, provides novelty and intense stimulation.

Just the thought of a global apocalypse and imagining the consequences gives people motivation. Predicting it on the news gets the news channels attention and ratings. Even if it never happens, the idea of a global apocalypse itself is capturing people’s attention.

Are you the author of the above linked tweet storm? If so I suspect from your "Lesson 1" that you're not very receptive to easy-to-find studies to the contrary of your position.

Yes. Also, use unitless values for line-heights, it's basically a shorter way of expressing it as a percentage of the font-size. This way, if the font-size changes (either a change to the site design or the user changes it), the line-height will be proportionally appropriate.

12pt equals 16px, 20pt equals 26.667px. The unitless line-height would be 1.6667. Regardless of how it's written, that's a pretty big value for regular-sized text (compared to larger text for something like a heading). I guess that's helpful in narrow views of nested comments, where the close button might wrap to a new line, below another clickable element.

.comhead {
font-size: 1rem;
line-height: 1.667

I hope you're right and I wish the project the best. I'm no where near California, but I think rail (and high-speed rail in particular) is one of the most efficient means of transportation devised, and should be deployed and supported.

Ask HN: Consumer GPS is not as precise in Italy as North America?
I’m spending some time in Bologna, and one thing I noticed is that while the data you get for you cell phone is very fast (many people don’t bother to use wifi) GPS feels noticeably less precise.

I am a largely disinterested outsider, but I have yet to see any documentation and examples of misbehavior. (This isn't to say they aren't there, just that I don't follow Rust intimately.) The recent banning of a Go contributor, and the ensuing discussion on HN and reddit was illustrative of showing behavior, showing instances where people asked them to correct behavior, and finally their suspension, I feel will correct behavior.
>The amount of support for drug prohibition in this thread really surprises me.

Most people I know smoke not because they are a drug addict or real smokers. They smoke because there are million things in life and work they cant get it out. And smoking is a pressure relieve system. That is why the trend is cigarettes with little Nicotine and fancy taste profile. Or E-cigarettes. I am willing to bet one could even create "cigarettes" with no nicotine and it will still sell.

May be cigarettes should be taxed by their content, where high Nicotine would be taxed higher or even ban. These sort of policy and system should be progressive.

IIRC the USA "too big to fail" bailouts were as loans which by now have all been repaid with appropriate interest, the citizens did not pay for a bank, they lent it some more money and got it back.
> the interesting implication is that it seems a fantastic time to build new long-term things. If you can get the resources and talent, you could build something to win the next decade while everyone else is scrambling to grab what is sitting right in front of them.

I have been having some thought experiments on company models that I think would be interesting. I've used the phrase "I like to move fast to move slow" to describe to people worried about rate of progress or deadlines on how long term thinking is actually faster in the end. Someone also recently reminded me of Phil Dunphy's "slow is smooth and smooth is fast". Another thing is that I think it would be interesting if a company acted almost as a non-profit in spirit, adjusting for sustainability of the company, quality of products, livelihood of its employees and customers, and not for growth and short term goals.

However, I am stuck for lack of good, concrete ideas. Some things that have become interesting to me are conservation, recycling, the ocean, social programs, etc., but I don't yet understand how to turn these around as businesses. One thing I see is the explosion of space companies, but I don't understand their business model outside of government contracts. So I can imagine a parallel of ocean-tech companies, although I don't see where the rubber meets the road. The idea of a recycling company is interesting to me, because I like the view that the company's goal should almost be to make the company shrink and not grow in that it should provide backwards pressure against the amount of stuff needing to be recycled at the end stage (e.g., providing companies with more sustainable products or materials that can be reused or recycled upstream).

Do you have any ideas? Who is thinking and writing about this? How does one capture the excitement and hype of space to the actual importance of the ocean?

It evens seems like a law to me that anything actually worth doing that will actually help people and the environment is not something that will make money.
> 0.1% of the population is getting richer and 95% of the population is getting poorer.

Haha if we were measuring them on literary merit most would be promptly dumped in the garbage. This is kinda just what early sci fi was like, it's rarely about the stories, the stories just contextualize ideas.
Semantic document search is one of the core use cases we see in the community (besides Question Answering) and Haystack was pretty much started because we saw that you need much more than just models. It's so much pain to integrate models properly with document storage (e.g. elasticsearch), route requests effectively in larger pipelines or track user feedback in production. Have you tried using DPR or sentence transformers for your case?

Disclaimer: I am one of the maintainers of Haystack:)
People may like the idea of small government, but that's probably the top issue of only a handful of Connor Roy types and college libertarians, and tangible issues like "property values" or "safety" probably matter a lot more to real people, and that cuts across party lines. For example, look at the racial segregation of every city in the US [0]. Nearly every city solidly votes for Democratic candidates (I personally am solidly liberal), but our cities are still brutally segregated. There are systemic reasons for this (namely in the Jim Crow era, the govt's FHA started a program that underwrote home loans and its criteria explicitly penalized areas where Black people lived, attended schools, or could easily access [1], and by backing home loans only to white people, the consistent, dramatic increase in home values created a massive racial wealth gap [2] that preserves segregation and trapped millions of Black Americans into clusters that could then be denied equal resources) and the side effects of asymmetrically depriving millions of people of many good choices is that a disproportionately large of that subpopulation (yet still extremely small percent of the entire subpopulation) will make bad choices (eg to rob or engage in violent crime). Hence the divergence between a cities political values on a national level and on a local level (ie quiet acceptance of segregation and the corresponding enforcement mechanisms).

This isn't to say Dems are worse than Republicans; a far larger percent of Republicans are explicitly opposed to even hearing about these grotesque racial injustices, let alone attempting to correct these injustices.

TL,DR: people don't form their beliefs from grand principles; we've evolved to pick positions that help us satisfy needs (ie from Maslow's hierarchy of needs). If we want less police brutality, we should endure the cost needed to repair the injustices of the past, rather than what we are doing (ie perpetuating that injustice).
