Ask HN: Keeping focused on learning while several layers of abstraction deep?
So say I want to write some software involving a specific domain. Let’s say the particular domain is very math heavy, in particular calculus. The parts of calculus find in upper level undergraduate programs. Now I’ve never been particularly good at math, in part because I didn’t really care about it when I was younger.

So basic in order to even get started on this project, I have to be at least somewhat familiar with

1) The tools I want to use to write the software
2) The domain
3) The prerequisite knowledge required to understand the domain (in the case the upper level math and a few other things.
4) The prerequisite knowledge for 3 (which involves more basic calculus, algebra etc. basically the stuff I never paid much attention to in school)

My problem is I have to learn that from the bottom up. Now if I was just starting at 2 or even 3, it would be no problem. My problem is at the fourth level.

At this point, I know the resources to use, but I find it extremely difficult to even get started, as it involves grinding through hours of videos, books, etc. to reviews / learn / relearn stuff that’s so abstracted and far away from my original goal that I just can’t keep the motivation. It adds significant time cost and removes the lesrning benefit that comes with a concrete, interest and is basically a return to everything I disliked about math when I was younger.

Does anyone have any advice on how one could motivate themselves through something like this?
Yes, but those are all non problems for anyone remotely tech-savvy. The point is, DRMs are hurting paying customers and do not even make it more difficult for pirates: when you download a torrent, DRMs are already completely stripped, so the only people prevented from consuming DRM'd content are paying customers with non-HDCP compliant hardware. That's insane.
> AIS is being managed by a Beijing based company.

What? No. AIS is a technical standard that allows ships to broadcast their position to avoid colliding with other ships in the area, it's not managed by any one company.

The companies that the article is talking about have covered China with a network of receivers recording the AIS transmissions of all ships, and until recently they were selling access to that surveillance feed to other companies who integrate data from multiple countries to enable worldwide tracking.

> In year 2018 they tryed to manipulate ships positions shifting them to another position (and did that).

That wasn't manipulation at the level of AIS recording companies; the ships themselves were misreporting their position because something was interfering with their GPS signal.
I deployed the open-source version of Canvas for use at a summer course at a university in Beijing (it was done remotely). Just getting it installed was the hardest part. We hosted on Alibaba in Hong Kong (no web site license required there). Support for the open-source version comes via IRC and was actually quite good. Show-stopper was a rapidly growing log file (due to a persistent error I couldn't figure out). Eventually had to create a cron job to regularly truncate it. Apart from that it was pretty solid. The other tricky thing was getting outbound email to work (not very well documented). Persistence pays.

Your uses of "nobody" and "every developer" have built-in, unstated assumptions wherein you exclude everyone who does not share your views. Unfortunately, that excludes me from further participation in this conversation with you.
That is a fair point. What I can say is that his loss weighs most heavily on my own children who never really got to know their grandfather. However, even though he was on a long, slow decline, he was still around for them to make memories with. Those moments are invaluable and I feel confident my father would happily go through it all again to know his grandkids were able to get to know him, if only a little bit. We still laugh about some of his shenanigans when his mind wasn't quite right.
> Crypto and stocks seem to be correlated at this point.

A bunch of folks from the Man Group and Campbell Harvey published a paper saying that Bitcoin specifically seems to have a positive beta with the US market:

> Finally, we are in the midst of another technological disruption in the form of the cryptocurrencies, including bitcoin. Some have advocated the inclusion of bitcoin into a diversified portfolio as an inflation protection asset. However, caution is warranted given that bitcoin is untested with only eight years of quality data – that lack a single inflation regime. Moreover, bitcoin is more than five times more volatile than the S&P 500 or gold. This high volatility could lead to bitcoin being an unreliable hedge. In addition, there is increasing evidence that bitcoin is a speculative asset and it has a positive beta against the US market.

* https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3813202

It's still early days, so more evidence certainly needs to be gathered, but so far as a hedge against inflation crypto doesn't look too good (especially because of volatility).

And Campbell published a pro-DeFi book recently, so it's not like he's against crypto generally:

You're paying with the time and skill it takes to maintain your own server on your own infrastructure. You have a bad storm and lose your connection to your ISP, your site is down.

I'd much rather put some money in a smart contract that pays a distributed set of CDNs to host my blog, ain't bringing that down.
While that might well be one reason, it should be also noted that Zstandard optimizes for the decompression speed with a reasonable compression ratio while Brotli concentrates on the compression ratio at the slight expense of speed (though it is very hard to do a fair comparison). This is evident from their defaults, where zstd uses a fairly low level (3 out of -7..22) and Brotli uses the maximum level (11 out of 1..11). But both have the decompression speeds far exceeding 100 MB/s which is the practical limit for most Internet users, so zstd's higher decompression speed wouldn't matter much in the web context.
Not the same. I honestly cannot hear differences between audiophile quality headphones or interconnects.

The typing experience of Topres' is noticeable whether you come from domes or mechanical keyboards. They feel in-between. I have arthritis in my right pinky. A 35g topre keyboard is perfect. (I also tried 35g mechanical switches but it did not feel as smooth).
Privileged white people who wants to preserve their privilege says that the poor white people are the problem and then kick those out in favor of black people. But the privileged white people are still there. And people wonder why poor white people don't like all of this "diversity" rethoric.
In this context it was court orders, usually over an ownership dispute between corporations. The legal fees etc, make it unlikely to be worth the hassle.

I've played RollerCoaster Tycoon, and I'm sure I've seen the developer's name more than once, but don't remember. You didn't repeat it in your post, so you probably saw it and immediately forgot. That's the extent of fame they got from that.
I would recommend that you consider Lunavi. www.lunavi.com

It all depends on your company structure. And it does depend on your workload as well.

I do keep my workloads up and working well in their infrastructure. They have private-clouds, they have public-clouds, and they have my cloud.

I use their private cloud for all of my crical services. As an engineering company that is always on, they always keep the services up. They have migrated it a few
times, and the downtime was always in sub-millisecond.

I have been known to call them late at night. They do take care of things.

We are just living in an era that is so focused on the cloud. Nobody gets pissed if an amazon hypervisor shuts down. Yet the technology has been there for 20 years to keep that from shutting down.

Amazon is walmart. Go find a lunavi.
Does Zstandard still have the junk Facebook license attached to it?

If none of the people alive today wants borders, how do you explain the existence of borders? What is your theory? And no, I don't know what 'mess' you are referring to. You seem to talk quite cryptically, to be honest.
Sure but if they delete the private key then they don't own it anymore either. It would be like destroying the car. And yeah, if someone steals your car and destroys it, you can't have it back.

There's also an easy fix for this. Make the NFT include a smart contract that requires periodic "checkins" that require the private key, and if the checkin fails, ownership reverts the previous owner or another address specified in the smart contract.

Or attach a smart contract that requires registration with a third centralized party.

NFT technology can interplay with existing legal frameworks and protections with the right programming.
> Cable channels were themed, but cable packages were not.

Themed packages did and do exist, though most channels for cable were normally available mainly through stacked tiers. But alongside the main generic tiers, language-specific (especially spanish language) and some other (sports, often) themed packages were available from many cable providers, and premium channels were often available in themed groups as well as individually.
> I can download any NFT and use it as my own profile picture.

You cannot, unless you have a vastly different understanding of what an NFT is than what it actually is. A NFT is not a picture, it's a cryptocurrency that only has one item. You could download the data representing a NFT (it's just ascii data), but not sure what you'd get out of that.
What I don't like HHKB is exactly the inexact trigger point.

These capacitive switches were originally designed for the need of extreme reliability, like for buttons in power station control panels, industrial equipment, etc.

Switches themselves are cheap, but chips for the capacitive readout for each button isn't, or at least weren't 20 years ago.

I want to make mechanical switches with equal reliability, and no bounce.

Netflix has a "Play Something" button for precisely that situation.

https://about.netflix.com/en/news/play-something-netflix-doe...

It can pick either something you're already watching (TV series or unfinished movie), or guess something based on what it has learned about you. Of course it's just the Netflix catalog, but that's pretty extensive.

It sounds godawful to me, so I've never used it. But it sounds like almost precisely what you just asked for.
You seem awfully convinced that this is an either/or situation.

I see no direct evidence that trying to help the Uyghurs necessarily inhibits our ability to pressure China to slow their climate destruction.
I don't have a problem with minority/contrarian views, but to use this site as intended, people need to be primarily oriented to intellectual curiosity, not hot political agendas. Those two sets are basically disjoint, so when an account is doing the latter, it stands out quite badly.

Of course, even within the latter category there's still a big difference between vandalizing the thread with flamebait vs. staying substantive and respectful.
ConstitutionDAO Fails to Buy the Constitution
Remember that streaming services don’t only compete with each other, but they also compete with torrents. Netflix won not because of being cool or good, but because it was way more convenient than torrents for the majority of content. This isn’t true anymore, as all major studios want in on the market, which makes the TAM smaller due to fragmentation and lost network effects. (It is common to hear people saying they won’t pay for more than 1, 2, maybe 3 services.) Ice is thinner than it seems, but streaming services know this.
The accomplishments of others do not in any way diminish your value. Enjoy the people in your life, give back what you can, and know that your accomplishments stand on their own and don't need to be measured against anything else.

> Social interpretation of the contract that the token is attached to.

So if the value of NFTs only exists because of a "social contract," what good are they? I could just pay the artist $1M for a normal JPEG they will send me via email (and for my money, an actual JPEG seems like it would be way more useful than a cryptographic hash of a URL to the JPEG).

In neither case do you "own" anything in a real sense, you have an artist communicating that you have exclusive rights to a bucket of bits.

The only value I can comprehend in all this is that of the ledger's utility in facilitating trading on the secondary market (since the artist doesn't need to go and vouch for everybody who eventually buys/sells the ownership stake in the bag of bits in the future).

It all feels gross to me. I can certainly appreciate that artists have to make a living, but the idea that the best way to do this is to crank out digital certificates to confirm somebody "owns" their work (but only in the sense that the "owner" can trade and speculate on that ownership stake) strikes me as bizarre and dystopian.
because the quality is not measured on whether you're a male or female but on the number of readers or clicks. Very transparent and very non-discriminatory. We all know woman write differently and generally speaking don't touch the bits and bytes but more the feelings/humanity behind.

For example, questions like does a chip have feelings or what about this twin brother does he feel lonely
This doesn't sound exactly right to me. "forced to move their crypto assets to things like [x]" just sounds like a different way to say "buy [x] with crypto" instead of with USD.

Edit because I was downvoted:

This genuinely goes against my intuition. The recommended alternatives were housing, food (don't know if the parent meant stock up on nonperishables or buy farmland & livestock), and equipment. This sounded like preparing for complete economic collapse. If that's the level of inflation we're talking about, then we have much bigger things to worry about than how crypto will be doing.
That's going into arguments on merit, though. The point is that trying to influence regulation shouldn't be seen as an issue. Berate the company for doing something you're against, but everyone has a voice, even corporations with more money to influence congress than the average person.
Seems like a good idea but it's tied to all the other nonsense happening on ethereum. Namebase seems better in my opinion because it is focused on DNS and nothing else. [1] Going forward I think that's how blockchains should be designed. Each one should be custom made for a domain instead of being universally programmable like ethereum.

I drive a 2019 Volvo as well (bought in 2020), and the "safety" features have activated for me maybe a hundred times! Out of those, safety system was helpful once (arguably) in that it reacted and activated the brakes the same time I pressed them (so it still wasn't really needed, but I can see how it would have helped when I was less attentive due to eg planning to switch lanes and looking at side mirrors).

All the other times, it's causing me frustration and pain. It signals a collision as I am avoiding potholes in a tight one-way street and cars parked on both sides of the road (yep, I am going to slam into that parked car for sure — at least it did not forcibly brake which would definitely cause cars behind me to slam into me).

It brakes when I am backing out of a parking spot into a street and vehicles appear from the other direction (a lane I was not getting into) — this happens so frequently that I am tempted to turn it off.

Pilot Assist on the highway seems to wait too long to slow down as I approach a car in front of me and then it abruptly slows down, yet it requires me to use the turn signal way too early if I want to overtake someone I caught up with: my drive was much more fluid with a simple stay-at-this-speed cruise control of my previous car.

I keep all of the "helpers" on (those that can be turned off) just in case I lose focus and because crashing once might be once too many, but I worry how much unpredictable behaviour is going to mess with other drivers causing them to make mistakes instead and crash into me.

Perhaps it works well for US roads, but European old-town driving is way too complex for safety features to keep up (esp as Volvo is considered to be among the best manufacturers for safety features, including these new-fangled ones).

Edit: and blind spot monitoring — the sales guy was so high on it, yet I don't see the purpose: it's right there flashing on your side mirrors so you have to look at them, yet side mirrors are large enough and concave (like on all modern cars) that if you set them up properly, there's really no blind spot a car or bike can fit in. And I still prefer to look over my shoulder to top it off.
Hiring a frontend team to expand our “full-stack component” library
Hey HN - probably a little odd of us to share a job listing, but I thought the community might find our concept of "full-stack components" interesting. Please do apply if this sounds exciting to you!
Unfortunately if you do not fully own your own ICANN registrar, for example, like Facebook [1], then your domain remains in the hands of the registrar; it doesn't matter what your WHOIS states.

I've looked into this exact problem because I wanted to know, what it takes to fully and completely own your own domain. The best way is to apply for an ICANN registrar accreditation which entails these requirements [2]:

- US$3,500 application fee, which is non-refundable regardless of whether the application is approved, denied, or withdrawn.
- US$4,000 yearly accreditation fee due upon approval and each year thereafter.
- $70,000 USD in liquid assets

In the case of Facebook, they were able to receive an expedited approval since link [1] indicates that their company will not be buying nor selling any domains. It just exists for the sole purpose of owning the domain. Why did Facebook do this, you may ask?

Well, social engineering. An Njal.la hosted domain was successfully transferred to Namecheap (through no fault of Njal.la) through forged German Court records [3]. So now, no one can socially engineer the domain away from FB and I suspect the vast majority of these companies.

RIP. Looks like I won't be owning my own domain anytime soon.

> Major inflation like we haven't seen since the 1970s.

The (demand-pull) inflation of the 1970s started because there was many years of war spending because of the Vietnam War. Once that wound down, then there was (supply-push) inflation of OPEC's oil embargo.

What we're seeing now is a sudden spike because of concentrated spending, much like happened due to the Korea War, where inflation lasted between 12-18 months:

These are very loosely held convictions...

- COVID will still be here but be thought of a little more like the flu.

- There will be some devastating natural disasters that induce more people into taking climate change seriously.

- AI will slowly cover more ground into people's lives.

- Cryptocurrencies will continue to be overhyped.

- US political tensions will continue to get worse.

- China will have domestic growing pains in the next few years, maybe cut back on growth or stir up some more regional tensions.

- Inflation will slowly give way to deflation and then the stock market is going to plateau or dip for some prolonged time.

- Conservatives will win control of congress in 2022 and the following 2 years will be a lame duck session.

- Trump or DeSantis is going to be the Republican presidential nominee for 2024.

- 2024 will be a really bad election for both parties

- Housing prices will continue to rise and not be affected by deflation and this will only get worse without significant and good government intervention.

- A black swan event or two mini black swan events that drastically affects a lot of other predictions.

Switch and Click is a fairly gamer-focused site, but they have some keyboard guides that might help you with deciding.

Maybe start with:

https://switchandclick.com/best-mechanical-keyboards-for-typ...

That said, they tend to be biased toward more traditional key layouts. If you're looking for an "ergo" keyboard - split, columnar, whatever - there are fewer review sites that cater to that approach. Also fewer options, though. Especially if you're looking for a low price point.
Although it may not seem like it, the people you look up to most likely also have these thoughts to some degree. Especially as you get older, the challenge is to learn to appreciate what you do have, instead of focusing on what you do not have. I would recommend speaking to a therapist to help you reflect.

One method to assist in developing this thinking habit, is to put a notepad on your nightstand, and every day, before going to bed, write down a couple things that you appreciate.
> Who determine which blockchain is the "legitimate" one?

You! And me! And the rest of the people who chooses to use one. Maybe not you in particular, but the people. Bitcoin is only as legitimate as the people having/wanting Bitcoin makes it. Which, by judging how much it's currently is worth, seems very legitimate.

Epic tried to do that, but Google made secret deals with OEMs offering them a cut of play store revenue if they don’t (https://www.theverge.com/2021/8/19/22632806/google-epic-prem...)

Part of the deal was that they couldn’t tell anyone about it without Google’s permission. So when you get a rejection from an OEM after you offer to bundle your store, you don’t get an explanation.
