I really hope this is true and becomes viable for as many people as possible as fast as possible.
The team that created this can really be proud.
I do agree that there's room for improvement. There's always room for improvement, but there are also limits to the transparency one should provide for an anti-abuse system. It's difficult for anybody except for an expert in this area to say what would be a safe and satisfactory way to expose appeal and remediation for false positives. In the example from the story it looks like the turn around time was just an hour for your case, which seems rather good. The fact that not all consumers of this data were as responsive looks out of Google's control, and should be taken up with those companies.

I don't agree with the premise of your last question. It's not Google's responsibility to protect the internet and provide a free anti-abuse database for other browser vendors, and yet Google does do this at significant cost. The fact that they don't do it perfectly is not a rationale for killing it or providing it with infinite resources.
I've been trying to figure out where the first z comes from. At least I tend to think "z" is for compression because of ZIP, but it predates that.

.Z was used for compress(1), probably because pack(1) used .z, but where did that come from?

My best theory is that it's from Steve Zucker who wrote pack(1) at RAND. There were other versions of pack(1) too, but if his was the first, it seems possible that he choose the z extension for Zucker.

Does anyone have more info or other theories?
> Most people can't program and are comfortable with Mac/Windows.

Yeah, being comfortable is not the point. The point is being free.

> No one here is shackling you to Signal.

No one forced me to use WhatsApp. I still use it and still have on my phone. I did manage to introduce some people to Matrix, setup their accounts and install their clients when they wanted to talk to me, but there is a whole lot more that I am just not close enough and that I know won't bother to switch just because I am asking them to.

If people ask me, I'd do the best case I can to get them to Matrix (or XMPP. I don't care as long as it is open and free) and I will help them whenever possible to switch away from centralized systems.

> I, too, would like to see a decentralized, federated protocol take off.

If you truly want to see a federated alternative grow, you have to help it. It's not going to happen if we just stand passively waiting for some big benefactor to show up and decide they don't want to control this space. Every big company will try to control this space and they will always have more resources and will use the advantages that centralized services (faster development, economies of scale) gives them.

Network effects matter. There is no better time to help people switch to a more free option than now with this massive WhatsApp diaspora. If people settle for Signal, it would be better than WhatsApp but it would still be a massive wasted opportunity. This is why I am arguing now so strongly.

(Lastly, do you know one software that I am somewhat forced to use? Slack. Do you know what can replace Slack with just a wee bit of training? Matrix. Two birds, one stone)

> Signal is no progress at all.

In the terms of freedom: no, it is not. The server is supposedly open source, yet the last commit in their repository is from April. If someone decided to fork Signal to run their own server, would they get a current version? Would existing clients be able to use the different server?

The answer is possibly, maybe it will require a lot of work on the people doing the fork. Which is fine from the legal perspective, but really far from the mark from Open Source ethics.
I buy a lot of pre-owned stuff, and sell or give away stuff I'm done with whenever possible, for the same reasons. I especially can't stand IKEA, because they embody throwaway culture so much, with their cheaply made furniture. And, if it prevents other peoples' stuff from being thrown out, while I get to save a little money at the same time, so much the better.
If you can provide the same proof of work features using less energy, you can demonstrably make a lot of money. Can you show me the evidence of that and the specifics of how to get the same block validation consensus security with less energy consumption?
It's complicated and I generally trust the CDC recommendations to be reasonable judgements. But they're not infinitely fine-grained. The rules in lots of places have healthy-ish 64 year old being eligible at the same time as healthy 20 year olds.

You could check how many codes were scanned and compare to how many puchases were made and fine business where this differes a lot from the best ones.

Which is why I mentioned both Chrome and Firefox, as while both implement some non-standard features, those tend to differ, so the intersection of their feature sets is pretty much the standard itself.

I was actually referring to "your extensions following the standard", but since you can't exactly test against the standard directly, I used testing against both browsers as a good approximation.
> “There is likely no causal relation between tulpamancy and the development of psychopathology,” a 2017 paper concluded. “Tulpas are an experience of plurality [in consciousness] that seem to coexist with optimal functionality, happiness, and mental health.”

My personal experience with one of these people tells a different story. The tulpa they worked to create was a "demon" that fucked them. The person who created this tulpa completely lost their mind and thought they were going to be the prince of hell.

I know, I know, annecdotal evidence and all that, but a quick trip to 4chan's /x/ board will uncover lots of other people who are trying to create a tulpa for sexual reasons who don't seem particularly mentally well.

I think it's irresponsible for the author to recommend this practice to people.

When you water fast you excrete salt with the water you're drinking. Beginners tend to drink far too much water to mentally replace the food, and so they lose a lot of salt. Gatorade when it was invented was an electrolyte replacement. Now it has a lot more sugar too. It was probably for the salt.

I mostly agree based on my own experience, I rarely get distracted by the lyrics alone, what gets to me is bass. Whenever a bass-havy song comes on I feel like my focus breaks, which is also why I started to listen to more jazz and similar, more easy going, genres while working and needing my focus.

Better for what? Even though I agree the Fediverse is better, it's useful to ask that question.

There seems to be a gap in the understanding around what the internet is and what it's for, and the gap is a social one around the concepts of the Private and Public spheres. I use caps for them because they are ancient, named concepts (look up "polis and oikos," the private sphere wiki page has been vandalized). The 90's internet was initially an extension of, and a bridge between Private spheres of individual thought, competence, family, niche communities of interest, and preserved this with conventions around both anonymity and tribal, benevolent-dictator style governance.

The Fediverse seems to replicate some of that, but to me it still seems like an anti social media reaction technology and not one that grows organically from a higher-order use case.

Social media was the act of hauling out these Private sphere relationships into a Public sphere, for which they were not adapted, and to satisfy the infinite vaccuum of need for attention that defines the Public. The Public sphere has always necessarily fed on the Private, and the Private used the Public for its civilizing social benefits. I'd go so far as to say that the insanity of the Public sphere right now is the direct result of scarcity of Private sphere culture to sustain it and it's cannibalizing itself.

Viewed through this broader lens, the Fediverse doesn't need social media features, it needs a Private sphere purpose for people to create and build things together, and then it can be more careful in adding bridges to the Public sphere.

Anyway, abstract comment, but the question shouldn't be whether the Fediverse is an adequate social media replacement, it should be, "what are we going to make?"
Touting as 100 LOC using only stdlib:

* may show that Ruby can do a lot on its own.

* may show that a developer doesn't have to depend on another gem just to get the job done.

The Ruby stdlib is powerful, and depending on another gem could bite you if it were to become unmaintained at some point.

However, low LOC and use of stdlib isn't always the goal for development in-general.

I want to develop solutions quickly that work well and are easy to maintain. If it's easy to learn also, even better.

In terms of the size of the code, even in text form, there's a lot I could do. I could reduce lines by replacing EOL with semicolon. I could remove unnecessary spaces. I could use shortest variable names. I could store a compressed version of the code in the file and then do eval of the decompressed version. Those don't make it a better solution, unless the goal is to obfuscate and/or minify it.

I know that's not the point, though, and I'm mentioning it only so that people will think about LOC as what it is- just a metric.
What about "Ada", "Miranda" or "Haskell"? First names, too, albeit ones much less common these days. ("Linda" the language isn't even in that category, popularity-wise, although the source of the name seems to be a weirder story)

Germany and France have rather similar regulatory setups to ours, so it does work in larger and more fragmented countries.

But as I said, I have no idea how it would work for USA. It's honestly kind of hard for me to imagine how any US regulatory bodies work, when they replace the leadership every four years, and often without a broad cross-party agreement.
Which is why USA has states, why not give them more rights? Currently US states have too little power or they could be run more like small European nations.
You're bombarded with so much negative news on a daily basis that it's nice to read something this inspiring!
What people forget is all the natural junk up there. Space is not "clean". Something like 100 tons of rock, mostly dust, falls onto earth from space every day. That isn't stuff in orbit, but given the capture effects of our moon there is likely a significant amount that does achieve some sort of stability. That amount probably outweighs everything we have ever put up there.

https://astronomy.com/magazine/ask-astro/2014/07/space-debri...

The real problem isn't that space is getting full of our junk, but that our junk is in a very narrow band of orbits that we use for very specific missions: Sun synchronous polar orbits used by imaging satellites. Look at how these orbits all cross paths at the poles. That's the danger zone. While the military cares deeply about these orbits, civilian infrastructure in space (geosynchronous communications sats, GPS etc) are well beyond any real danger. Or, at least they are in orbits where danger from natural debris is vastly greater than from space junk.
Also unknown is the number protected by prior infection. Anywhere from 10-30%.

I think we’ll see R’ start to plunge during summer due to weather and never climb back up from increase in immunity. But “back to normal”. January earliest.
You are right that the collisions will dissipate some of the mechanical energy will be dissipated into heat and technically collisions will reduce the duration it takes for the mass of debris that are in orbit. I am not sure if that has a significant impact on top of the atmospheric drag though.

However, the Kessler syndrome is not about the total mass of debris in orbit, but the number of individual debris. So while before the collision we had 2 nicely aggregated debris, after the collision you will have thousands of small ones.

The small ones will tend to deorbit faster on average, because of the loss of energy mentioned above and also because their aggregated surface area increases, but you still have more debris. And when we are talking about multiple decades/centuries of lifetime, these debris will collide with other satellites, creating a positive feedback loop, increasing the numbers of debris exponentially, at least initially.

Obviously this is just the beginning of the process, which will end up with a maximum number of debris and then a decrease towards zero, but that timeline is extremely long and therefore not really relevant to us.
> made-up number, but doesn't feel far off.

Pew Research says 18% report getting news primarily from social media (fielded 10/19-6/20)[0]. November 2019 research said 41% among 18-29 year olds, which was the peak age group. Older folks largely watch news on TV[1].

Petri nets are a quite general model of concurrency that has also found use in many places in computer science. They are used in model checking, and also as the foundation for giving a semantics to BPMN, for example.

I think it's not unreasonable to consider Petri nets as a generalization of automata (finite or infinite) with concurrency. Just like automata, they find applications in many places depending on how you further extend or restrict them.

> the US bureaucracy is neither flexible nor creative as evidenced by its refusal to buck top level orders and it’s continuing slowness. These are signs of a decaying system.

Yes, and it’s because the priorities rank as follows for each individual:

1) personal liability

2) organizational liability

3) utility

Where liability includes both legal and public relations consequences. It’s exhausting to constantly think about open ended and unintended consequences that you might be held accountable for, with no recourse.

Brain drain usually occurs in countries with deep-seated cultural issues. That is not something you can solve with a couple of laws.

We don't need to re-engineer food. We need to de-engineer it - rebalance it in favour of nutritional quality, and away from prioritising yield mindlessly.

We already have an obesity crisis. We know that our over-reliance on carbs and demonising of fat is contributing to it, or outright fueling it. We know that our food is poor in vitamins, so basically all urban dwellers must take vitamin supplements.

Part of why our Western diets are so calorie-rich and nutrient-poor (while being allergenic for many people) is because we've mindlessly pursued food yield, rather than food yield balanced with nutrition. Most food items are processed or contain processed ingredients, or junk ingredients that bulk up the volume/substitute for more expensive ones. A lot of people are catching up to that and trying to compensate, but it's a nearly-vertical uphill struggle while you're not well off, because good food tends to be more expensive.

We need to stop that. We need to bring back affordable, healthy food for the masses.

The classic dystopias in literature described a supposedly future time, in order to criticize the present. The classics: Clockwork Orange; Farenheit 451; Brave New World; 1984.

Now there's a new trend in this genre, where a supposedly possible future time is described in order to glorify the present, and defend it against all possible change, good or bad, because "it could become worst". Handmaid's Tale is a good example. It makes catholic religion look so good it's sad. The total absence of criticism towards a religion tied with the institutional rape of thousands of children[0], and hatred of women, for instance, is absurd. And the fact is the raping is still going on as you read this. Of course this is only a single point of failure and absurdity amongst many others.
Whilst Huxley, Orwell and others were driven by passion and rebellion against injustice and misery and desire to change life, low quality scripts like the one on this TV series are clearly motivated by making money while surfing/exploiting current social media cultural "trends". Disgusting.

I don't think it's necessarily imaginary that we are friends. Consider that a functional community is characterized by an overarching sense of cooperation and mutual support that is NOT tied to an individual's identity. HN provides succor to those who look at the world in a certain way, with a combination of probing curiosity, healthy skepticism, and intellectual humility.

It's true that there are some elements of history that might remove you from that sphere. But identity? There is no identity that would remove you.

As for getting "real" friends, that's rather tough for two reasons. Real friends are in constant, casual contact. This means proximity. Tough to do in general, and impossible in Covid times. Second, those three qualities are very rare. The only reason it seems like they are common is because the internet was created by and for us, and so it seems like we're everywhere. We're not.

So, yes, if you ever want to talk, my contact info is in my profile.

I don't think so, there are no external standards to tell you if your Tulpa is valid or otherwise. It is your own. Now, if you're regularly meditating or then thinking without distraction might come easy but don't let that stop you from trying.
It is true that corneal transplantation is a thing since decades. However, a corneal transplant, like any transplant, has its issues. Rejections can still occur, and the healing process takes a long time, usually not less than one year, involving constant adjustments.

I slowly teaching my colleagues (and learning myself) to use no-sound messages in telegram. If something does not require headsup/asap level of attention, I better send it with no sound, as if it was email in old days.

Still it is not convenient to hold onto a send button to do that. I wish messengers operated noiseless by default and had a special “ding” button to request attention. It could even be used alone, just to remind your peer that they are blocking the important process and it would be nice to see an update on ETA.

I think the main function of the vaccine in the initial stage is to lower the amount of people who need hospitalisation after contracting covid. So giving limited doses to the people who are most likeley to develop severe symptoms seems like best strategy to achieve that. Even if it pushes back date of achieving herd immunity a little.

So prioritizing health care workers (they can easily contract and spread) and old people (a lot of them need hospitalisation) seems like a good idea.
