I’m not disputing that XMPP can be used to build a modern chat environment with history and group chat. The question there is one over the primitives that the protocol provides. As you say, these features (and decentralisation, via FMUC) are provided as optional extensions in XMPP. In Matrix, they are the core primitives of the protocol. To put it more concretely: Matrix works by replicating chunks of conversation history between servers - not by forwarding stanzas. And there is simply no concept of a 1:1-only coversation; all conversations happen in rooms which may have an arbitrary number of users.

On the federation/decentralisation question: yes, matrix servers federate with one another networkwise. But the data they exchange is decentralised: it is equally replicated over all the servers which participate in a room, using a merkle DAG to enforce integrity (like git, or a blockchain).

> No extensions means no customisation for the purpose at hand or for future enhancements

This is not true. Matrix is extensible at the data level - you can put whatever you like into it and define whatever semantics for it, a bit like HTTP. But the API itself evolves as a single entity released by Matrix.org, and folks are very welcome to contribute their future enhancements into it.

> So tell me again about how matrix is so different?

A loose analogy could be svn versus git (architecturally, given XMPP is much higher perf than Matrix currently). Classic XMPP MUCs are centralised to a given domain like a svn repo; if you try hard enough you can decentralise them (FMUC), just like svk existed for svn. Or alternatively you could write a new system with different primitives like git.

I hasten to add that the analogy is not exact and Matrix isn’t remotely as successful as git, but it’s an example of where sometimes it doesn’t hurt for a different technology to come along and shake things up.
I feel I already addressed that question in the GP, where I wrote that journalists are a special class and why they are a special class.

I think a more appropriate analogy would depend on how the person leans.

It would be like telling a conservative that they stole America from the Natives and should give reparations.

Or it would be like telling a liberal that it was the colonists that made America what it is today, so they don't owe the Natives anything.
Very common across Europe. I'd say almost universal.
HN doesn't allow for people to delete their account, a lot of forum type websites have the same rule.

Not for a startup, no, but in my experience it works well as a lifestyle business. Companies pay well for this kind of work and it seems the number of spreadsheets they want to have replaced provide enough work for the next few decades to come. Better the replacement isn't half-baked though...
What's the difference between "whataboutism" and perspective?
Maybe in addition to thinking about society, we should think about sex workers as humans.

Specifically, how by forcing their profession (which weighed morally right or wrong, still exists and will continue to) into a legal gray area we actively make them vulnerable to further exploitation.

For example, by criminalizing websites that are involved in the profession, we strip their ability to use the internet openly for their own safety and education.

By threatening their business with legal charges, we disempower them against less scrupulous elements of the legal system (law enforcement or prosecutorial). Resulting in extortion or coercion.

So would legalizing sex work and bringing it under a regulatory framework "change things" for everyone? Yes.

But not doing so is cruel and dehumanizing enough that I'm frankly disgusted to live in a society that feels prosecuting sex work is the "right" moral choice.
We have plenty of common causes say fighting cancer. We can link arms, sing songs, fight cancer then go back to trying to dominate each other globally and establish our mutually incompatible values as the global norm. Playing this off as Americans being brain washed is just naive. They are literally our enemies unless you have conveniently forgotten Korea.
In Arizona, it is not against the law to drive over the speed limit. But it is against the law to speed, or drive too fast for the given conditions. Driving over the limit is evidence that you might be speeding.
If everyone else is driving above the limit, and you aren't, you are the one causing the danger.
In a sense, I am. In another (as you probably know), it took a dose of guts to leave Italy (and friends, parents, etc).

GTK doesn't have anything to do with that; Thunderbird and Firefox use native widgets to implement XUL on macOS. It's mostly a platform decision based on numbers of users and if there are any technical pain points supporting earlier SDKs.
Parent didn't say he wants to remove that freedom. Look at it as evangelizing of agnosticism.
Just because there are details to work out doesn't mean it shouldn't be legalized.

Imagine trying to legalize alcohol for the first time. What if kids drink it? What if people drive after drinking? We managed to work through the follow-on effects with a system of rules that left most people feeling content and safe.
At first I felt insulted for implying the left is easy to manipulated, but then I realized I'd be more insulted if I was in the right wing because you imply the right-wing doesn't care about the sexual molestation and exploitation of children nearly as much.
I wonder if the CCPs censorship department will one day be as powerful as the RIAA or MPAA?

What's scarier is that in this day and age, anything you say on social media can be a fireable offense. Wasn't there an American teacher that was fired this week because he dissed the military?

Or the numerous professors that are in trouble for complaining about BLM disrupting their class?
I'll strongly disagree in turn. I personally know some successful founders whose business, in one important facet, could be summed as "get rid of those painful Excel spreadsheets". It's not the use or not of Excel. As with most things, and as TFA discusses, it's about the pain factor. Spreadsheets are, far and away, the greatest success in end-user programming to date. But like all software tools, their usage can grow into painful places.

Do the users have massive, error-prone and/or time-consuming workflows built around those spreadsheets? Is it very hard to bring new staff up to speed, or to keep existing staff compliant with process, or to meet day-to-day business goals with those spreadsheets? Is there no solution between "painful spreadsheet" and "$X,000,000 contract w/ bigcorp" to solve those problems? If 'yes' is cropping up in answer to those questions, then lifting the logic from ad-hoc process around spreadsheets into software may be a good idea and/or a good business.

The biggest impact of keeping it illegal is legitimatizing a whole class of stigmas based on primitive superstitions. It's time to shed that baggage and grow up.
Intent is hard to determine since someone's intent is not directly accessible. It can only be inferred from behavior and other surrounding evidence.

However, the inclusion of intent into a law doesn't inherently require any ambiguity in the law itself. The way in which intent factors into a statue can be crystal clear.

Sure, that's one of the points I made.

There isn't really any more precise timekeeping equipment available to us than atomic clocks here on (and near) Earth, so using those are expedient.

In principle we could measure the spectra of the relic fields, but with current technology we can't do that for the cosmic neutrino background, and while the cosmic microwave background (CMB) is an attractive option (we have lots of instruments measuring it in excruciatingly fine detail) its utility as a quasi-universal clock is based on picking out an ideal observer who sees no non-cosmological redshift (i.e., no contributions from proper motion or local gravitation), and such an observer isn't really physical. Converting local measurements of the CMB to an ideal observer's in a way which achieves precision approaching that of our terrestrial atomic timescales depends on understanding our own local (~ Mpc scale) environment better than we do today.

(Probably we will get there by using CMB observations to steer local oscillators, much as we do in atomic clocks, H2 masers, and so forth, and use those steered oscillators to predict CMB spectrum on the (well-supported) assumption that it is that of an ideal blackbody with a certain temperature).

However, we'll still record actual observations at local CMB temperature (perhaps recording what the "universal" CMB temperature would be if we were a "universal" observer). We are still stuck with the problem of position of the observed object, since we cannot directly observe the CMB temperature at an event like this flare.

In other words, the coordination (or if you like, localization) problem here isn't solved by switching to a different set of coordinates. Indeed, a different set of coordinates might make things worse (which was the thrust of what you replied to, and essentially what you write yourself).
It's mentioned briefly through a single paragraph but not much beyond that.

"He lived through the war under the name Grzegorz Krochmalny and hid in an estate near Lviv and at a manor neat Nowy Sącz. He gave private lessons in exchange for firewood, oil and milk.

If you can get them to use Quickbase/Gsheets/AirTable or similar instead there's a big improvement. Still hacky, but you know what's out there and roughly what it's doing. And better centralized access control and backup.

That's sort of the work I've been trying to do... if you read through the whole post I give it my current best shot and use graphs and videos that do a good job of setting it up using laymans terms, especially the MinutePhysics series narrated by Sean Carroll.

Basically the idea is that life is a process which maximizes complexity as entropy increases, by its very nature... if you consider the whole universe, there are no structures we have observed that are as complex as the structures we observe in living organisms.

The complexity of the biosphere would dwarf the complexity of the rest of our entire solar system... as in, the information required to describe the entire solar system and how it proceeds from state to state, including the storms or Jupiter and Saturn, would be trivial compared to attempts to model all the life on our planet, including the mental states of each of the 7 billion humans and the interconnected relationships of all the other bacteria, plant, fungi, etc.

This maximization occurs as life seeks to continue replicating and adapts to each other and any environment that it possibly can, even the harshest on our planet. The most advanced organisms on the planet are those which have the most complex nervous systems and thus the most complex behavior, including us (again, the complexity of the human mind most likely dwarfs the complexity of most other organisms... proven simply by being able to occupy states that allow it to understand and communicate the complexity of other organisms).

So, my thesis is that the purpose of life is to maximizes complexity, but not as an absolute, since complexity creates fragility and issues with diminishing returns on energy input. This is why I say that it the purpose is to maximize the area under the complexity curve, rather than simply maximize absolute complexity. See this graph - https://goose.us/media/complexity_entropy_graph_filled-920px...

Not sure if that was a good or not, but I appreciate any feedback on the attempt!

At present, there's zilch. WSJ focuses on plaintiff attorneys.[2] :) LA Times seems to only have an editorial[3], which swipes at big tech, but is surprisingly competent.

I've formed an impression of the big press, NYT et al, in contrast to say industrial/professional media, that even when they manage to get facts right, they pervasively manage miss the point. It reminds me of coverage of unfamiliar foreign cultures, after the local foreign bureau has closed. Context, and reality check, and insight, and clue, all become unavailable. Even here, even dealing with their familiar political DC subculture.

exactly this.

I believe Americans are not doing enough of their own research into things, blindly believing that their best interests are in mind by business (and multi-nationals) and by the government.

Many Americans I've spoken with expect diabetes drugs will miraculously cure them of diabetes, when in fact drugs, and most modern medicine, is to manage the pain / outcomes of the resulting condition rather than do a root cause analysis and solve that (holistically) problem and why it's occurring in the first place.

I believe there's little understanding of how out of hand free-market capitalism can get and how toxic its effects can be on the general public. Despite the American views of how the market should be it seems there's expectation by the people that they're somehow protected.

Look at all the research coming out, all of the reality tv show medical advise. Much is flat out wrong. Much is radically incomplete and meaningless results are published simply to get ones name in a science journal. This creates the problem for those who do takes the proper approach to doing their own investigation rather than absentmindedly consuming media and believing it to having to vet the content they're consuming for validity. So yes, the contents of the minds is manipulated and woefully wrong.
Cheers I'd not heard of a gear cutter before.

This looks like a helpful approach to a tricky topic! I'm curious how the post-deploy migrations work when you run all your migrations at once, from the beginning, e.g. in Circle CI or when onboarding a new developer?

Also, do you do anything to protect yourself against migrations written at time t_0 and then run much later at time t_n? I've seen a lot of problems there when migrations use application code (e.g. ActiveRecord models), and then that code changes. (My solution is to never call model code from migrations, but there are other ways.) This isn't really specific to your article I guess, but does your approach making managing that harder? Easier?

Does having that details table help at all when you have migrations on a long-lived branch that is merged after other migrations have been added? Or is the solution there just to rebase the branch and test before merging it in?

EDIT: I think this blog post by the Google SRE folks is great reading for people thinking about migrations and deployment:

https://cloudplatform.googleblog.com/2017/03/reliable-releas...

I've never been comfortable with rolling back migrations in production, but their plan changed my mind that it can be done safely. Is your approach compatible with theirs?

>I question the methodology behind this figure. The nature of the decentralized network makes it difficult to get good estimates. All I have are anecdotes. Yes, the overwhelming majority of users are on Mastodon. However, I personally interact with several users on several different Pleroma instances and a couple on GNUSocial instances, and I did not seek them out for this purpose.

However they are the exception. Because the overwhelming majority of users are on Mastodon, the Mastodon developers have the power to modify protocol implementations. If it was closer to an even split, any breaking changes would fracture the community, while in this case some smaller groups may be lost.
The only reason not to would be because of additional beauracratic overhead of supporting such an edgecase.

I run a very large number of web performance tests and GA and the Facebook pixel do not add 400ms either alone or together of user-perceptible speed decreases. They will take some small amount of main thread time for parse and compile, but they are loaded async and generally not performance problems on the (hundreds) of pages I have profiled.

Intercom and other live chat solutions are typically the biggest offenders on modern pages. They serve 10-20x the script as GA and the Facebook pixel.
