> The answers I get have taught me that most programmers don't have a basic understanding of how the internet works outside of their narrow specialty. This lack of a rudimentary mental model is one of the largest contributors to wasted time and effort in web application development.

I'm curious what specific mistakes you're thinking of that application developers make when they don't understand computer networks. In my limited experience, the rudimentary abstraction "messages are sent, they're not instant and they might not make it" has generally been sufficient, aside from DNS issues. I learned some networking in college (CS241 at UIUC) and it was really interesting, but I feel I've forgotten almost everything from lack of use. Maybe I've done terrible things as a result. I think I and many others could really benefit from a list of common pitfalls by networking newbs.
I really don't get the appeal. It's not even mechanical.

You're paying just for the branding.
>Well, I like that Al Jazeera exists and their coverage of many things was good.

I'm not criticizing their reporting (because I haven't read much of it) or saying that knowing who finances them necessarily results in a more objective reaction. That is, certainly there is prejudice that comes into play.

I'm saying that it is demonstrably possible to have gone for years generally aware they exist without being aware they are state sponsored, and not encountering any mention of it.

I would expect more people to know about RT, but my point is, regardless of how you view people who are ignorant, the proportion of people who are ignorant matters. It has some influence on how they affect society.

There's a genre of articles that link the CIA to things and makes a big deal about it, like the most sinister imperialist forces in the US government are necessarily controlling it. So it seems to me that the idea of the source of something tainting it is universal.

Saying people should be aware of what RT stands for cannot be taken as an argument that they are.

>The "interrelated" argument is dangerous, because it cuts both ways

So? Rejecting it doesn't produce a license for inconsistency.

If we agree that Fox News is unreliable when reporting on Republicans, does it make sense to expect them to be objective in reporting on Democrats? Does it make sense to expect them to be objective in reporting on Ukraine and Russia?
Why some vi users map the ESC key to CAPSLOCK?
is there a book teaching b-rep?

I know half-edge and similar data structures for polygon modeling, but I seldom see any materials on b-rep.
It's also easy to forget how big of a deal human health is. If you can spend 5% more energy to unlock 5% more enjoyment and productivity, you can use that extra productivity to engineer better, less polluting systems. If every high density apartment building had a much much higher air and sound quality than the average house, it would also entice more people to live in denser areas.

Moreover, well-built, well-conditioned, comfortable buildings are also very efficient, so the only reason not to build for quality is up-front capital cost, a problem that can be solved with a combination of improved technology and tighter building standards for ventilation and noise.

There should be a way to shop for places to live with an easily comparable air, sound, and comfort quality score, so that there is pressure to improve.
Unless you are outright promoting commercial stuff, I feel for writers who are relatively unknown and would like to get feedback on what they write, HN is a good place to post links.

This is not different from posting interesting links you find. It is not self-promotion as you are not selling anything here. Instead you are trying to see if the content resonates with others and kickstarts a discussion.

In fact, I see it as no different from the comments we are writing here.
Many of us have been watching the horrifying developments in Ukraine over the past month and are wondering if and how we can help. Many are donating money to humanitarian causes but some are also wondering: can we help in a more scalable way through our tech skills?

There is a major problem with getting accurate information about what is happening on the ground in Ukraine. In the world of the internet and smartphones, there is an abundance of video, image and text accounts coming out but they are overwhelming, unstructured and contain a significant number of fakes. This leads to proliferation of misinformation, confusion and the ability of malicious actors to spread their own fake narratives, prolonging the conflict and causing additional damage.

Here is a prominent example (as of March 25). The city of Mariupol is surrounded by Russian forces with hundreds of thousands of civilians trapped inside. The city is heavily bombed and people live in basements for weeks. There are reports of hundreds or even thousands of civilian deaths and of a major humanitarian crisis with the lack of clean water, food and medicine. There is an account of the situation from two journalists, who have recently escaped the city: [1], [2]. They report Russian soldiers being responsible for the situation and provide videos and photos. There are also accounts from pro-government Russian media about Mariupol, for example: [3], [4]. They report Ukrainian soldiers not letting civilians leave the city and providing videos, photos and possibly witness accounts.

Can we apply skills in big data, analytics and machine learning to help?

We believe we can use the power of:

- thousands of people to collect, label and connect pieces of evidence

- dozens of ML groups to run their ML algorithms to establish truthfulness

- data experts to systematize and make evidence widely available and searchable

This can help:

- more people around the world to be better informed instead of only following sources from one information bubble they happen to be in

- governments to better understand casualties and damage

- volunteers on the ground to coordinate their efforts more effectively

- people who lost touch with relatives and friends in the conflict zone to find more about them through image search

- the world to document and preserve information about the big historic event

… and in many more ways, which we can’t think of ourselves right now.

Here is a short link with more details about the project: https://bit.ly/ukraine-evidence.

We are looking for the project leader and 1st ring team members (see the last section of the document for details). Reach out to ukraine.evidence@gmail.com if you are interested and share the document with others who might be.

> They don't affect gameplay

This opinion might vary by the person and the game. I was playing some free-to-play game the other day which was like you described - it had a store and some tokens, and a way to slowly gain the premium token as you played.

But I found there to be something deeply gross about it which did impact my gameplay experience. I’m playing a game (rather than doing something else) because I want a curated experience of fun. Tokens like this make the relationship adversarial. In this case, the game has some mechanics which it keeps waving in your face - “quick! Click now to spend 2 whatevers to have a 4 hour boost!” And I have to actively avoid the shiny fun part because it costs real money to do. It makes the experience tiring in the same way shopping is tiring. Is the game trying to be fun or not? Pick a lane.

That said, I enjoyed Dota2 for many years even though it had hat stores and loot boxes full of art. I’m not sure what the difference is - I think I just never really had to resist the pull to pull out my credit card in dota. And I payed way more as a result! I chipped in a few dollars each year for the international prize pool, and that was a blast.
Netflix Conductor is great alternative to Temporal. There is a fully managed offering for this as well. The biggest advantage is that it’s quite simple to understand and has great visualization of flows.
Sure. I have a few.

I do't think its useful to "address the market holistically". The housing market is heavily variegated, and any honest assessment must take this into account. It's not one market, it's many different markets, and possibly sorting them even into just a binary classification makes more sense that treating it as if it's all the same.
Oh absolutely, well said. I miss those days when time spent at the screen was intent time. For a long while now for me, it's basically just been a TV replacement.
> Sheet music is sound storage which is very space inefficient and allows only MIDI capability. Twibright Optar stores digital music with full digital sound capability. Recommended format is 32kbps AoTuV Ogg Vorbis which allows storage of around 45 seconds of music per page with acceptable quality. Musical skill is not necessary for playback anymore. And music album can now literally be an album.

Lol, i wonder with opus if you could have an audiobook thats thinner than the book.
Can Wachy be used to trace kernel code as well? And would you need to do anything specific to get that to work? (How would Wachy find the kernel sources?)

I was thinking this would be pretty cool to use for debugging device drivers on embedded devices especially w.r.t latency.
I didn't read the whole article, but from the schematics it looks like they are exploiting thermal electronic noise and applying a half-bridge rectifier to it so it produces very low voltage power.

On one hand, it's clearly bullshit due to the extravagant title claiming to violate the 2nd law of thermodynamics. On the other hand, if a system is sufficiently small than it can violate the 2nd law, locally. It seems the tour de force in this case is that the scale can be somewhat enlarged by the very low power of thermal electronic noise.
When the press says "cools" they often mean only "decelerates". Prices may indeed still go up. However, interest rate changes are working against house prices at the present time.

One in five houses currently listed in San Francisco has had its asking price reduced at least once. Sale prices are still high and time to close is still low, though.
Its also a nuclear state, if Chernobyl goes haywire things are going to get dirty really fast.
There's a lot wrong with society, and the expectations that are put on men which are ultimately damaging isn't talked about enough. Broadly, I think there's a sense that men must "earn" their worth through achievements, i.e. you are not born with inherent 'worth'. This belief is inculcated into us at a young age, explicitly or otherwise, and constantly re-affirmed by our media and culture as a whole.

There are two ironies to this. The first irony is that no matter what some people do, they will not reap the 'rewards' that was promised to them. This becomes obviously true when we remember that we don't live in a just world, at all, of which this fantasy of cosmic justice relies on. The second irony is that this fantasy of cosmic justice is inherently damaging and perpetuates injustice. We need to drop the idea that good things follow good people.

In your case, you're seeing it play out in the dating world, where issues of loneliness and the natural, human desire for intimacy are dismissed as being superficial complaints from basement-dwelling "incels". I am sorry that you experience this. Moreover, there appears to be no correlation between passions for a number of hobbies and lifestyles with what people are ultimately attracted to. Personally, I think we should drop the whole idea that there's a list of things men need to do before women can find them attractive. The same goes for women.

I don't know you personally, and I think these kind of issues hit at the most vulnerable parts of people so I don't want to sway you with any specific ideas of my own. So the only advice I can offer is cautionary: be wary of adopting only a masochistic epistemology. It is tempting to see the world through the lens of "I will never be attractive to women, no matter what I do" and finding every example of this to reinforce it. Everyone who has experienced the darker depths of the human soul knows that there is a pleasure in believing that whatever hurts is true. This leads to a vicious cycle of thoughts. This pessimism must be tempered by an optimistic epistemology. What that bountiful optimism looks like to you, I don't know, but from my experience, it is a missing 'second half' to the world that I had to consciously find which brought a healing and resiliency that deepened my relationship with myself as well as others. Best of luck.
This argument is a losing battle, so I’ll leave it alone. I just know it wasn’t a Doctor walking in looking for a medical office. Don’t ask me how I know, sometimes you just know.

There’s a vape store around my way that sells weed, and other drugs (not legalized here yet). Don’t ask me how I know, I just know.

For what it’s worth, just on pure number crunching, I don’t even know how a developer making modest six figures can even THINK to bid on a 1.8m dollar house, even WITH double income from his wife.

So, what the fuck is going on?
Have you tried Netflix Conductor (https://github.com/Netflix/conductor) - if you are evaluating between Airflow - this could be a great alternative - scales well and gives you option to write your workflows in code as well as config.
Best way to resolve issues like this is stop working for companies like this. They are toxic.

I’ve never understood the window tiling complaint. While MacOS doesn’t have tiling built in, it’s readily available for free. Are there features that aren’t available in those applications?
Resilient to corrections? Nothing is. They are just the last to correct.

I found this a thoughtful and informative read, and I especially like the term “proof of force” to describe fiat currency, which I hadn’t heard before.

I don’t think this is going to significantly change the way most people on hacker news think about bitcoin, but I will say that it changed my perspective on the problem of network scalability.

If you think of Bitcoin not as competing against Visa, but as competing against the bank settlement network, then it makes a lot more sense.
You can always try Bresenham’s circle drawing algorithm.
Games are many things to many people. Don't play the ones that go against your personal values.
I don’t doubt that many have achieved great things in Akron, but was rather arguing that the relative level of opportunity is lower in Akron (median income 23K) than SF (54k) or NYC (32K). The typical person is more economically productive in cities like NYC or SF.
One interesting thing I've heard when working for a company that had microtransaction mechanics is, "Non paying players create content". By engaging in the community, even if in isolation they cost the devs money to host, they create the content and also the audience for the whale's behaviour.

I think a lot of us have a vision of a childlike, halcyon "purity" of experience, in the joy of gameplay itself, that we would seek and enjoy with or without other people's presence, with or without money. We want to experience that, we also as programmers (who may have learned to code because we like games) often have a deep desire to create that, to give it to others. It's like the "Beatific Vision" in the life of one who likes games.

We all know there always was a need for money, and passionate creativity exists in its margin. I think the complaint here really is that this margin seems to have less room in the eyes of the complainers, because the pull for money is present in virtually every game loop now, as opposed to being outside of the box...

A question I want to ask is, for newest generation of whales, is there a memory of some great, memorable exploratory rush in the big spend for them, part of a broader set of social interactions that gave them great joy and built them up in their community? Would their experience with the game due to this purchased power inspire them in any way, maybe to make some potentially positive, impactful life decisions? Or is it literally just a borderline scam at every single possible level?

I dislike microtransactions of any kind strongly, but I am at least trying here to be open to the possibility that someone who did them was able to feel something similar in relationship to them somehow.
Certainly. I’m assuming that much of Ukraine will remain in Ukrainian hands. I’m wondering what the immediate needs of a post-war society are.
So, maybe microfilms would have a record of the fact that the speech happened, but most aren't going to have the full text of the speech. Recordings of every broadcast would also be unlikely to be stored at most libraries that can be described as 'easily accessible' [1]. "I Have a Dream" is famously copyrighted; without MLK and his associates/estate managing the distribution, it would be very difficult to get access to it. I bet the libraries of the South didn't all have it available straight away, for sure.

> Sure, it's not comparable to the reach of today's instant broadcast via Internet, but it was the equivalent of the time.

But I guess that's partially my point, right? The instant broadcast/archive-by-default nature of YouTube is new and unique to our time; trying to refer back to historic figures as your precedent for having access to it seems a little hollow to me.

[1] I grew up in more sparsely populated areas (and, also, in Australia), and perhaps that changes my perspective on what is reasonable to expect for access to libraries pre-internet.
Why is std::is_copy_constructible_v std::vector MoveOnlyType  true?
Hard to see how this works when Brownian ratchets don't.

Also: "Léon Brillouin in 1950 discussed an electrical circuit analogue that uses a rectifier (such as a diode) instead of a ratchet. The idea was the diode would rectify the Johnson noise thermal current fluctuations produced by the resistor, generating a direct current which could be used to perform work. In the detailed analysis it was shown that the thermal fluctuations within the diode generate an electromotive force that cancels the voltage from rectified current fluctuations. Therefore, just as with the ratchet, the circuit will produce no useful energy if all the components are at thermal equilibrium (at the same temperature); a DC current will be produced only when the diode is at a lower temperature than the resistor."

No offense, a statement like that (and the OP) without factoring in location means nothing. There are definitely 100k lots in places people want to live, some of them are pretty big. While everyone may not want to live there, there will be plenty of buyers.
This is indeed a downside but there are workarounds -- The wikimedia foundation put out a good blog post talking about getting HTTP connection pooling for PHP

TLDR they used envoy proxy as a sidecar container. So to your point its a pain but still achievable
What are you plans for addressing the fact that most modern network innovation is invisible to the end host’s kernel, let alone the application.

I’ve struggled to find a book that doesn’t just hand wave layer 1 and assume layer 2 is ethernet everywhere.
The indie game scene is still pretty great. Tunic just came out last week. It's super fun and basically a single dev.

I wrote my own free open source browser game.

"N-gon is a physics-based single player 2-d platformer shooter with hundreds of different power ups. You move with the keyboard and aim with the mouse. The core game is done, but I'm still adding new content.

These are naive and unrefined technical indicators.

- there's only price/volume, it's very poor in terms of information. Smells like an academic with only access to a free database.

- it's really the classical technical analysis 101 indicators, studied 10000 times in research articles.

- you would need wayyyy more indicators to get a meaningful model.
Doesn’t quite ring true to me. Bitcoin was blowing up in price way before Tether came around. Although the Tether setup is shady, it’s not propping up Bitcoin. I would rather say that when Bitcoin falls next (it does in cycles) then Tether may collapse.
Completely wrong. It would exist either way because recurring revenue is better for business.
So nasically program footprint as a namespace? Hrrm.
That doesn't solve anything, since the version you have could have the issue and you wouldn't know it if you hadn't audited it.
Thunderbolt doesn't use DP for video when in Thunderbolt mode.
Google is experimental. We're both the product and research subjects, not customers, for their free offerings.

Their transition into the paid/enterprise space is very interesting. I'm very excited for them to find a non-advertising revenue stream, as it could help Google to stop being evil. They're still a very amazing company.

However, their approach providing free services is a bit subpar. I've ran into so many table-stake bugs that simply don't exist in MSFT offerings (e.g. copy/paste between Google office applications often breaks formatting).

Thanks to our mid-size enterprise contract, I can get someone to tell me that not enough people are complaining about it for them to fix it. Meanwhile, from asking my teams at work, everyone struggles with lack of polish across their applications.
Mozzila turned itself into a privacy browser, not a browser with privacy.

Google added things like WebUSB, Bluetooth, all kinds of web app APIs Mozilla rejected because of tracking risk, etc.

Mozzila killed their coolest features like FlyWeb.

They just haven't kept up with Chrome, and their vision is way too "privacy at all costs" rather than allowing users to decide. They don't seem to share in the modern idea of web apps having full native parity.
As someone who's read Lyn for a while, there wasn't too much "new" here. Strangely for it's length it felt like a cliff notes of some of her other pieces on bitcoin and petrodollars.

That said there is plenty here that people can engage with in good faith without reading it all word for word.
Yeah I always wonder about the click-through rates of popovers asking users to install a native app. They have to be tiny.

“Like our content? Install our app so we can send you notifications and monetise you better!” - no, I’m not enjoying your content. I haven’t even read any of it yet. Your obnoxious pop up is the only content I’ve seen so far and it makes me want to pour water in your server rack. I’m not going to install your app.
