You can build better receivers but eventually only so many photons are being sent. Prior to 1921 people were sending out very little radio waves and the signals where vary weak. The you might move things back to say 1920 with the very first radio station but it really wasn’t putting out much power. Things ramped up fairly quickly though, at least assuming something built a truly massive detector at 100+light years.

For comparison look at what we need to do to detect messages from the voyager 1 at 1/400th a light year, realize that’s sent from a directional antenna and we know exactly where to look for it. A signal that’s ~1/1,600,000,000th as strong would take some serious hardware even with more advanced technology because you can only collect 100% of the photons in a radio transmission quickly you need a physically larger device.

I see such behavior here in Germany sometimes, too. Like everywhere else in life, there are nice bottle collectors, and there are assholes.

One collector gave me a sticky, wet butt, because he snuck up behind us in a park, "stole" my half empty beer bottle I placed next to me, and then proceeded to empty it out right there. It was one of the very few times I had trouble controlling myself not to hit somebody... I managed to control myself in the end enough to avoid violence, but was still angry enough to call the cops on the guy. Cops told him to not show up in the park or surrounding parks for the rest of the day, and when they asked if I wanted to press charges (technically it was theft and damage of property), the collector waved a 20 Euro note for "cleaning costs", which I took instead. I felt that was punishment enough.

Then again, there is plenty of bottle collectors who are rather polite, and humbly ask if you're done with the bottle and if they can have it. And a lot of people also gather together their empty bottles in a pile when they see a collector approaching.
1-star reviews usually only say the product sucks. I find 3- or 4-star reviews to be the best and usually most detailed reviews, with pros and cons of the product listed.

I think 3x is the wrong target here, it's the learning by listening model aka "The Nurnberg Funnel" (or possibly Nuremberg Funnel for German speakers) that is harmful.

I'd rather have a more focused lecture at 1x speed, the same as I'd rather have a good textbook, but skimming in both cases is fine if you want some info but the presentation available is too simple for you.

But, learning by doing and finding out what you don't know by doing is important. That applies even to crappy end of chapter multiple choice quizzes or whatever their audiobook equivalent is, but I find project based learning to be where it's at for really cementing knowledge without boredom.

edit to add: I'm not sure about the bit about pre-textbook lectures is historically accurate. I was under the impression the modern lecture mostly derived from the time when books were expensive, non-mass produced tech and the single copy was chained to the lectern and the person reading it out was doing so in order to let people make their own cheap copies.

I'm a big fan of video lectures that people consume in their own time, but more because they can slow them down, and rewind, not because they can speed them up. If you're always speeding up, you could probably just get a denser text

It's been 44 years in France. It was older than current facebook's age when facebook appeared. France abolished the guillotine more recently than this privacy law pased in France. When I was born, it was already no longer discussed.

It's not 200 years old, but it definitely is OLD.
Overall, for bigger and more complicated systems you would have an architecture that is peer reviewed and communicated internally.

Afterwards you have individual components that have their code reviews and still need to follow industry best practices. I think external code reviews is great idea as it could allow the team to focus more on conceptual reviews and consequences to other systems.

That's kind of convenient actually IMO. I get rid of the bottle, I don't have to give them cash. Win-win.
For a large fraction of gifted students, all American schools have to do is stop forcing them to waste their time on things they already know or pick up 10 times faster than the average student. Let them read a book on the topic being taught in the back of the class.

A couple of my best teachers did let me do this, but it was quite clear that it was the exception rather than the rule, and it depended entirely on their idiosyncratic and countercultural sense of concern for the well-being and development of all students, even gasp the talented ones.

There is absolutely zero effort involved, and the idea that this takes away from other students is just good old Fear, Uncertainty, and Doubt (FUD).

Don't FUD the conversation without evidence, please.

> Is one supposed to run anti-malware software over it (or keep it networkless)?

As the biggest vector for malware is not an insecure operating system but user negligency (e.g. by opening malicious attachments in e-mails), it is advisable to have anti-malware software on every machine, regardless of the operating system.
I am writing a fully decentralized application and in doing so have learned a lot about the concept. There has been a lot of interest on the subject over the last few months so I likely need to write a document about the things I have learned. Some quick things:

* Security is wildly different in a decentralized model compared with a client/server model.

* Decentralization is about one thing only: maximum autonomy.

* Federated systems are semi-autonomous. They are a move towards decentralization but not completely so. With decentralization you only need an application that send/receive agreed upon instructions.

* Anonymity and privacy are opposing qualities. Decentralization is not about either but enables one or the other.

As I have been exploring this subject I have formed some criteria for decentralization:

* Address based (IP addresses or identifiers that resolve to an IP address without third party consultation, no DNS)

* Protocol agnostic (what ever two parties can agree upon)

* No third parties (no servers or message proxies unless you own them)

Think about it in terms of snail mail. The post office moves packages around without opening or inspecting the contents. The contents are never stored in a database and could be broken. It is address to address communication.

Decentralization allows for personal or organizational devices to be remotely connected as a large physically distributed computer:

* A single file system, cross OS.

* Remote application execution, such as Steam’s remote game play.

* Content on demand. Push media out to your friends or access their computer and pull it off yourself.

I'm sure that somewhere has crazy rules but the general idea of a secured loan is the lender can easily take your security if you don't pay the debt. If not for that it isn't secured, is it?

Car loans are secured on a car. If you want to just borrow money with no security you can get a (likely far more expensive) unsecured loan if the bank judges this to be a good risk, or take an overdraft on a current account or use a credit card, all unsecured debt.
Can't the focus be on being less cruel generally?

I think this is creating a false choice by making arbitrary definitions and using them as the reason to write off an issue. Another form could be "why should I focus on violence against women when that would mean ignoring violence against men" or a given race or whatever.

yet another reason to move off of Facebook entirely; and to have a backup of everything.
For plastic, you’re right. I think they use the same blanks for multiple sizes of bottles. For glass bottles, I’m not so sure. I don’t remember many plastic bottles in the 1980s. They were coming, but I still have glass in my head for all but 2L bottles at the time (but I was really young). But the point is the majority of bottles you’d see for recycling would have been glass (or cans) at that time. And the amount of materials used for packaging was different back then.
I remember there was a proof of concept that beat a similar warning in Flash by displaying a background filled with similar text.

This worked, because Flash merely overlaid the full screen warning over what the app displayed. A huge dump of random text meant most humans missed the warning.

Ah, you're assuming that everyone agrees that ANC always uses an early low-pass filter, and hence there'd be no high frequencies in the noise-cancellation signal. Makes sense.

However, I don't agree that ANC always uses a low-pass filter, and it seems from kalal's followup that they are also talking about the using the full original signal. So the two of us were not talking about introducing high frequencies but about somehow enhancing the high frequencies already present, and that's what the figures I gave above are for. So we've been talking across each other. I apologise for my part in that.

("Amplitude" was a simple technical term to replace woolly terms that were being used, just as you are the first in the parent-chain to say "low pass filter".)

> However if the aliens had a big telescope surely that radius would expand?

I think a more interesting question is how far away could we detect a civilisation equivalent to our own, using our current technology. Otherwise you can assume aliens (or our future selves) with arbitrarily sensitive detection equipment limited only by whether or not the detectors are inside the speed-of-light radius of the emitting civilisation.

IIRC our most powerful transmissions have been from NORAD radars looking for missiles coming over the north pole. In some ways we are now emitting less detectable signals, e.g. with lower power 5G cells and fibre broadband replacing good old radio.

"how much decentralization do we need?"

I think, that hits the nail on its head.

Many people are happy with MANGA basically owning the Internet and many people aren't.

If we look at companies bending the knee for China or shutting down accounts, simply because they have different moral than the account owners, it's clear that we need much more decentralization than we have right now.

How much? I don't know.
Yeah. I programmed the Amiga and it was awesome - no middleware, no crap, if somebody else's code ran better then their code was better. Same with the Atari ST.

To me the most interesting part about this is the fact they know their platform causes enough issues without sufficient means of remedy as to need a dedicated team for their own people. If they had to eat their own dogfood instead, things would get fixed.
This is now complex as there's two parties.

Maybe the company would pay you more but the recruiter either:

- told them you're cheap, mistakenly or not

- wants to get you in cheap so they get follow on work

- doesn't know you expect a lot more

- is getting a bonus if they find suitable cheaper candidates

- doesn't yet know what you're telling us and so hasn't passed on the feedback on the poor offer.

- would be happy to fight for higher pay as they're paid a % of your annual rate.

You miss the point. Many USA based companies happily comply with EU regulations and offer their services. Some do not, because they do not want to comply with the regulation, which specifically forbids generating revenue from user data.

What you are complaining against is that some sites are built around selling user data and EU makes it hard to do so. The cost you are talking about is your inability to form certain contracts. Every regulation comes at certain cost. However, in this particular case the data protection and safeguards against selling of such data are the basis of regulation, not the consequence. GDPR is born to enforce this cost and this cost has been integral part of surrounding debate.

It is not people who are not willing to talk about this cost, but rather data broker lobbyists, who try to sweep this cost (data protection) under the rug who do not want to talk about this cost. Every time someone makes a counterpoint against broad statements protecting data broker interests (e.g. personalized-ad supported websites cannot exist profitably), that is the debate you are looking for.

> I cannot understand the mindset of someone who would feel justified keeping the car

No-one said anything about feeling justified keeping the car. People take issue with the backdoor. I too, would rather clean the car, take my stuff, and return it with an apology (if the bank refuses to negotiate an extension to the loan) than find that a backdoor has been used against me and it's just all gone one day.
That's not the point. The car has a capability to lock you out, and all it takes is for someone to activate that capability. I don't want that in a car.
I had the impression, the money of companies is used for lobbying, effectively controlling the "stick".
Honestly this is well known among any decent marketer, but what the article seems to miss is the answer to the question they pose:

>“Would this customer have bought without this ad?”

Even if the most likely answer would be "Yes", I think the proper question would be:

"Would this customer have bought MY PRODUCT without this ad?

Here the question is most likely "No" (unless we're talking about retargeting but let's leave that out). Who would they have bought from if they haven't seen your ad? They would have bought from someone else.

So, even if personalized ads are pointless, these companies are right about their advertising offers being a driver for sales. They could drop the whole "personalized ads" angle and they'd still be right since they would keep driving results.

Now are all the results sustainable? Down the line, they won't, because the more players get in the bidding game the higher the cost per results will be - and no personalization will help small businesses on that front.
A lot of people use ESLint and Prettier. If you look at the roadmap/issues for those products you'll see that some feature requests cannot be programed, but can be understood without knowing the full context of the business and codebase.

At the same time, if you are fixing a critical bug and you use enum instead of boolean, who cares, just push the fix, but it doesn't hurt to have a gentle reminder show up in your github PR that it is an option to use boolean instead.
Some years ago, New York passed a law on recycling. For some reason, people seemed to be surprised when it turned out that those showing up at the grocery store with carts full of recyclables were neither lawyers nor stock traders, but rather the homeless.

There has never been a better time to build websites. Or web apps. Or SaaS apps. etc.

There has never been a harder time to get the word out about them.

Which makes sense. The more you make it easy to build them, the more there will be. But the world population increases slowly and only has a finite attention span. More and more websites are competing for a pie growing much more slowly.
It means that if (big ifs!) (a) the South African peak is truly a peak and (b) vaccine-acquired immunity staves off severe illness to the same extent that infection-acquired immunity does[*], Europe is not in for “quite a ride.” As in South Africa, cases will briefly peak at a very high level, but without a corresponding high level of hospitalizations or deaths.

[*] while only ~30% of SA’s population has been vaccinated, some estimate an additional 40% of the population have been infected, for an overall immunity rate of ~70%, which is comparable to the vaccination rate in the US/Europe.
This isn't how it works in the US. In the US, the car is titled to the bank until the loan is paid in full, then the bank transfers the title to you.
