You're staking out some pretty strange territory, if you think it's wrong to refer to the movies based on The Hobbit as "the Hobbit movies".

The Lord of the Rings movies are not the Hobbit movies at all, not being related to The Hobbit.

From experience I can tell you that IPSec is much faster than OpenVPN.

I have no issues getting Gbit over IPSec (Strongswan), but with OpenVPN I always maxed out around ~400Mbit.

Cop-out from what? I'm not the one posting an article diagnosing the psychological problems of a broad and ill-defined class of people, I'm responding to one specific article that I think is bollocks.

To be clear, it's not that I don't think there are a lot of over-achievers that are overcompensating for something, of course there are, but what do I gain from trying to analyze them in the abstract? It's an impotent form of mass-judgement that I can see no use for except as a crutch for one with fragile self-esteem. Everyone needs to live their life as they see fit, and it will go better if they can be honest with themselves, but I'm not going to sit in judgement of someone who is not harming others merely because they exhibit obsessive behavior.

Nice, though, you could probably get better performance by using an analogue integrator and sigma Delta encoding. Probably even better if you down convert (multiply with expected frequency first) You can swap bandwidth for resolution.

If password managers are going to become popular for end users it needs to be something that’s built into the browser and interopable. I’d love to see this turned into a standard that all browser and device manufacturers (when I log into an app on my phone the password manager should be integrated) can implement.

This is essentially signal normalization. Sensor systems operate on a narrow band of inputs using non-linear components (like e.g. diodes). Adding noise is like raising the DC voltage on a signal so that it shifts the signal to within your operating parameters. For example, for a transistor amplifier to work, the base diode needs a 1.4V difference to turn on and amplify a 10mV source signal.

What makes white noise interesting is that it has a zero DC component (on average) by randomly adding energy as often as it subtracts, while passing through analog components (like a capacitors where R(s) = 1/(sC) in s-domain). In my view, this is still a form of amplification.

Adding Gaussian noise around your source frequency is certainly source amplification because it's equivalent to attenuating the surrounding "noisy" frequencies for the benefit of your sensor equipment. This would increase the signal-to-noise ratio, but you have to know what the base frequency is you are trying to measure.

I hope to be corrected by the signal folks, but it seems misleading to me that "the frequencies in the white noise corresponding to the original signal's frequencies will resonate with each other," when resonance does not occur in the signal, but in the resonant body of the sensor, and so this is more about sensor system calibration than boosting an unknown source signal.

It seems that the practical implications are that you can have simpler sensors (that work in a narrower band) if you can cheaply control the input noise based on sensor reading.
No, we haven't. You are absolutely right that this would probably mitigate the deadlocks. However,

(1) the deadlocks/WSREP was a problem annoying us, while the query performance was a problem leading to real customer complaints,
(2) as I see it right now, we would have needed to take complicated steps to ensure that all application nodes always connect to the same database node; just a hardcoded priority would probably not be enough,
(3) a mechanism for (2) would likely make us loose more of the advantages of Galera, e.g. short failover downtimes

This is interesting for its notes on Google's organizational history and what it got right/wrong, but the bits about other companies don't seem to make sense to me, particularly Facebook:

> Facebook is kind of nothing. It’s a product company and I (personally) don’t think the product is very compelling. I think they hit a moment and will see the fate of MySpace in time. I can’t pick out product innovations that were particularly awesome (other than incubating on college campuses and exploiting sex more or less tastefully). And, their infrastructure is pretty crude which means they’ll run into the problem, eventually, hiring the kind of people who can do the kind of scaling they’re going to need.

Surely a company that services billions of users (the kind of scale only rivaled by companies like Google) and worth $500b+ got something right when it comes to scaling organizationally/technically. They're Google's arch nemesis when it comes to recruiting, for one. Strange to see such dismissal from someone who purports to be a high level manager at Google. Anecdotally, I've heard that Facebook is less bureaucratic than Google, particularly during promotions.
The equivalent of bad hacks / technical debts exist in the financial industry, it's just when they blow up the cost gets socialized onto the rest of society. This is basically what happened in the financial crisis.

Yes, it is a good tool for one of my projects where I need to cleanup some html, is very good for DOM manipulation.
It is also a very good tool for simple webpages, If I have some mostly static thing that I need to show I can render that on the server with PHP and have jQuery insert it on the right place and handle some events,
This is exactly the point I wanted to make.

I add that the original Beetle also lived on because VW were able to extend the life of the original tooling, which they’d replaced when they moved to the Golf in Germany.
I would be surprised if a majority of new projects with a JavaScript library weren't using jQuery. I personally moved on a few years ago and I suspect that's the case with many people who respond on HN, but there are still plenty of valid use cases, particularly when JS needs are simple and backwards compatibility is really important.

If you're doing projects with light functionality and already know jQuery cold, you really don't gain much from React, Vue, et al for that project. You may gain something personally (career path, different way of thinking, etc), but that is a different topic.

For anything slightly above the basics, I'd recommend Vue as a great alternative to jQuery. No build tools required and it's easy to stay in the realm of plain HTML, CSS, and JS. It also "progresses" really nicely if you have more complex needs later on -- that would be a main benefit over a tool like jQuery.
Ask HN: How to self-learn math?
I have a new found appreciation and fascination for maths and would love to study maths from the bottoms ups. I'd love to know the paths I should take and books I should read.

EDIT1: If the question is very broad, it'd be much helpful to know how did you learn math? What courses you took, books you read.

EDIT2: My current proficiency level is pre-high school mathematics as I didn't pay much attention in high school, learning effectively nothing.
Our development setup currently does not need Docker at all. In fact, it does not need a lot more than git and a recent Python version: https://docs.pretix.eu/en/latest/development/setup.html

I agree that this is an opinionated setup and I do see the value of a development setup that mirrors production closely.

(1) During testing, in-RAM SQLite databases are really fast and well capable of running tests in parallel. We have a test suite of ~2000 tests that currently needs ~4min to run on a modern notebook with four threads, so this matters.

(2) pretix is an open source project. If we'd only have a small number of developers in an in-house team, I wouldn't care at all. However, there are many people contributing small and large features and fixes to pretix, and many of them are drive-by contributions: People fixing a problem they just experienced and then leaving again. I want to make it easy for these people, even if they use operating systems where installing Docker first might be a hoop they do not want to jump through.

That said, deprecating MySQL at some point would also force all self-hosting users of pretix to go through all the steps we did here, so this wouldn't be viable in the short term.

Um, given that criminal behavior by Enron on the "open market" was the only time California ever had rolling blackouts, you've got a bit of work ahead of you to justify that statement.

Decentralized generation with local storage is a great way to prevent this kind of blackmail from ever happening again.
Sure, there are often problems differing between the databses. Our Travis CI configuration runs our test suite against all three different databases: https://travis-ci.org/pretix/pretix/builds/351704035

However, having SQLite at hand for local development/testing makes things easier.

In my experience, real-world concurrency issues (that you are talking about) are always hard to find in manual/automated testing, or do you have a good strategy of trying that?
I stopped using jQuery after I started a rather large Angular project 2 years ago.

We haven't in depth, as they only advertise with their sharding and distributed query features etc and less with their HA features (if that is even in Citus Community).

Sharding data is something we won't do before we absolutely need it, since disk capacity is not at all our constraint right now and our scaling problem isn't that its hard to serve many tenants at once, but we may need to be able to serve one tenant with very high concurrency the minute their tickets go on sale (which would only affect one shard on a usual sharding setup).

Are you using Citus for HA? Would love to hear your thoughts!

QE: Not really. The problem with QE is that it's a purely monetary operation, so the only way it could lead to real economic growth is if it somehow lead to more lending. But arguably debt leads to instability, and besides it's like pushing on a string: it doesn't work when people don't want to borrow. It'd be better for the government to outright buy stuff or give people money.

Depressing economic output: Absent inflation, economic output is proportional to overall spending, so a policy like this can't depress economic output almost by definition.

However, I'd say there is a risk of directing that output towards useless things, plus there's the risk of favouritism that leads to hidden inflation via inefficiency (see also: military industrial complex). So it matters where the money is spent.

Personally, I'd like to try something like a "citizen's dividend": just hand out money to all citizens equally each month (or permanent residents, you can argue the details), no questions asked and no strings attached, but vary the amount based on current inflation. That is, increase the dividend when inflation is low, scale it back when inflation rises above some target.

So kind of like a UBI, but with a macroeconomic motivation rather than trying to replace the welfare system. It also appeals to me because it's a sort of direct democratic approach to macroeconomic management: people can literally vote with their wallet about how the money is spent.

Where to read more: modern monetary theory is a good keyword to start with. I found Randall Wray's book very interesting. Warren Mosler's "7 deadly innocent frauds" is less academic, but it's available online and interesting since it comes from a practitioner instead of a theoretician. Though I admit it's been many years since I read either.

I did not mean "lonely" as negative. But people sometimes go "oh I dont get it instantly I must be too old for it, cant do it and kids get it naturally". And that is not the case, kids are figuring it out slowly and their play is more incapable then they think at first. However, they "feel" like they know what they are doing whole time, so learning is pleasant.

But also, I dont really think Minecraft is like lego. You can play it like lego, but you dont have to.
Possibly. That's worth testing and only takes a small sample of borax, water, and a sacrificial stinkbug or ten.

I'd arrived at the findings above through direct trial, after attempting a few others -- alcohol also works, though it's much more expensive.
California used to be just like you describe.

Then a bunch of criminally negligent politicians, of both political parties, in the pockets of Enron "deregulated" the industry out here without sufficient safeguards and sold off a bunch of power plants in the name of "efficiency and competition".

The current kerfuffle with Calpine is fallout from those actions almost 20 years ago. Since CA doesn't control any power plants directly, anymore, they don't have a lot of negotiating leverage. This is a transient problem because as the article points out, renewables and batteries are wiping out the ability of these producers to exert too much influence as the spot price of electricity gets increasingly controlled by supply rather than demand.

And, to be fair, California hasn't really had any electricity problems since Enron died.

Perhaps, but it is not completely random. It is composed of the first letters from the words making up a phrase (which by the way is not from a poem/prose or any existing writing; entirely my own), some upper & some lowercase, prefixed and suffixed with a sequence of numbers and symbols. So it has much more order than a random sequence of 46 symbols, but unless you keylog/phish me or something like that, I don't believe it can be brute-forced anytime soon, which is why I went for a (over?)long, unique phrase.

This is built into any operating system. If an application frees up memory, the OS doesn't throw that data out, it just marks it as "can be overwritten" and ensures that it actually can be overwritten without data loss (so, if the data in RAM has been changed, it writes back these changes to the hard drive).

Yes, you can actually manage RAM more efficiently for your application, if you just reserve a whole bunch of it and work inside of that, but at best you'll trick your users into thinking your applications is fast, but it's not actually in the interest of the user. If they wanted to dedicate all RAM to your application, they would not have opened a second application.
This is what I wanted to know too. Speaking as a non-physicist and a layman, that's almost the first conundrum that occurs to you when reading about black holes from popular science literature. How is it that gravitons can seemingly be exchanged by the pair of masses for any body to feel the pull of a black hole?

I still don't quite get "the gravitational field at the border, within our observable universe, is intense enough to whip itself up into a self-maintaining recursive but sustainable loop" (especially the self-maintaining, recursive part. How?), but I guess one would need a good understanding of GR to go beyond this level?
