Anyone know a good traffic simulator for cities that includes pedestrian behavior?

I always wonder if, at busy pedestrian intersections, it would make more sense to have the pedestrian flow stages and the vehicle flow stages be totally separated. Cars waiting to turn right for ~30s as pedestrians walk is kinda crazy.
In Rome I can think of one church (San Clemente Basilica) that was built on top of a pagan temple, which then had another church built on top of it, which then had the current church built on top of it. You can in fact tour all levels of it. Much of ancient Rome lies at a lower level than the current city, so those buildings are now basements or buried. In many cases that is what happened, not wholesale knocking down of the old buildings.
Those headlights.... But why???

Everything else looks great BTW.
The reason I am willing to attribute it directly to religion is because there's a kind of 'natural selection' that goes on with regards to people's religious attention such that those who practice their religion exclusively in private end up being those that practice dying religions (as they can't effectively compete for mindshare against those that proselytize.) Obviously that's only an approximation, but even so it is a pretty good one, as it is not a coincidence that the spread of specific religions correlates with promotion of public religious practice.

Most religions will associate the promotion of their religion as a good deed, and they are willing to overlook many bad deeds that lead to it for those reasons.

I've said for years, the American system gets itself all tangled up because we (want) to teach two entirely different writing systems to children: we start with manuscript (printing) and then once the kids are used to that, we consider slapping them with cursive (and a hideous Palmer hand or a derivative to boot).

You want to teach cursive effectively? Drop manuscript training entirely and start kids on the joined-up writing in first grade.

3 of the 4 examples of right wing rhetoric I quoted were uttered publicly by right wing elected officials (including the highest current elected in the land), not by people entertaining themselves on Reddit. The fourth was shouted publicly by crowds in Charlottesville.

The difference between right and left rhetoric is one of kind, not degree. Ethnic nationalism is not a motivating factor on the left today.

Class tensions and frustration over the distribution of opportunity and wealth - yes, those are prominent left-wing issues and that rhetoric is often expressed via insensitive metaphors targeted at the very wealthy, but again, it's not even comparable to the rhetoric of ethnic nationalism.

I don't know about "killing the web".

I do know that the existence cert authorities greatly undermine the notion of a chain of trust for certs. It was perhaps a necessary compromise, as there are so many certs that it isn't practical for people to verify the authenticity of them as they should, so they have to rely on someone else to do it for them.

Personally, the use of cert authorities reduces my trust in certs signed by them. I don't consider a cert trustworthy just because a CA (that isn't mine) has signed them. I consider them more trustworthy than just accepting certs without any validation at all, but that's not high praise.

I also don't accept the bundles of root certs that are provided by operating systems or web browsers. Those bundles include too many (one is too many) root certs that exist purely to allow undetected spying and MITM attacks.

I think the essential problem is that our entire cert trust mechanism is broken.
That doesn’t require infinite length, just indeterminate length and more than a single round (on average, or with certain rate).

And I’m not sure that it doesn’t apply to the case where:

A) You can’t determine when the game will end, and

B) There’s very often several rounds.

That seems to cover “society”, in a broad sense.
Not anymore -- while they still offer that feature, it's downplayed in favor of a Netflix-style rotating library of games that are downloaded and run on local hardware.
I threw a 1TB 860 EVO into my PS4Pro for relatively cheap (maybe $200 back then?)

Since the console is very low on writes they can probably make these like 0.3DPWD for fairly cheap at Sony scale.
Well, the comment was in reply to somebody asking for the postgres feature to be locked down similar to MSSQL's - and I think the "FUD" spreading commenter just was trying to explain that it's already similarly locked down. Sure, it could have been a bit more explicit about that, but attacking that as FUD seems mighty strong.

Does everyone agree AI is better than self discovery?
I get that computers can do things quickly, but this massive push into AI and pre-selected candidates seems somewhat misguided. Perhaps for high level areas, but not for something more meaningful or deep? Currently, I'm building this site https://nextcept.com/Feed/Network to help people find others to work with that they get along with. Ie. cofounders, early teams, new hires, etc. I continue to get suggestions that I need to offer suggested or recommended candidates. I suppose I see this to some degree, but am I alone in wanting to be able to wander through candidates, learning about them individually, until I find someone interesting. Obviously we're trying to make this wandering process more efficient, but it seems like something unique or something that stands out would be difficult to capture in an algorithm. Is this a misguided belief? Does everyone want (believe it's possible) the ease of Tinder but the depth of a real connection - magically?

Elevate: A New Accelerator from General Catalyst and Hubspot
I'm excited to share a new online accelerator program called ELEVATE from General Catalyst and HubSpot. For anyone working on your startup this summer, I highly recommend it!

ELEVATE is an online accelerator focused on helping early-stage startups learn the principles of inbound marketing and create a growth playbook tailored to the needs of their companies. Startups will be invited to attend an exclusive, four week program where they will join MasterClasses led by HubSpot experts to learn inbound methodology fundamentals, and case studies led by General Catalyst portfolio founders and executives to better conceptualize how to apply these principles. In the fourth week, startups will complete a MasterClass and case study focused specifically on fundraising led by General Catalyst investors and portfolio founders. At the end of the program, startups looking to raise capital will have the opportunity to submit their pitch for funding.

I think “play slowly” in this case means “take it out during odd moments of the day such as waiting in a line or riding a bus and poke at the puzzles instead of catching up on Twitter”.

I am pretty sure that even a first-generation ZIL interpreter spent the bulk of its cycles flashing the cursor and waiting for the player to type something.

Yes, but the EU has both the ability and every economic incentive to refuse any permanent agreement that doesn't give them at least the same level of UK lock-in. The "temporary" is a figleaf to try to sell the WA to domestic voters and MPs; I don't think anyone takes it seriously.

have you run 4K video through things like Handbrake? They've been proven to seriously reduce the amount of space (and, therefore, bandwidth) that video files need, and considering that 4K videos have about three times the resolution [1] they have a lot of space to gain from it. I would guess that there are appliances that can run some flavor of compression in real-time to get 4K to stream well. Yes, it will take more space than 1080p will, but that's to be expected.

I've only dabbled with it a bit, but I think of it this way:

One could say that at its inception and heyday, Perl more or less defined what a "scripting" language could/should be, making things like string processing and list/dictionary handling very convenient, mixing multiple paradigms, and facilitating community modules. That certainly seemed to have influenced JS, Ruby, and Python (Perl's scripty siblings) but I think many people would say these are now considered better executions of those core ideas.

But are they really the apotheosis of this kind of language? How else could you grow/change a language like this in order to make it more convenient, powerful, or interesting? (Or less politely: what would make something as great as Ruby or Python look relatively blub-ish?)

I see Perl 6 as an answer to that question, perhaps in a similar way that one might say Rust answers that question for systems languages.

I would have less of an issue with this if traditional media organizations where less bias and publicly retracted stories or incorrect information. It seems that, in modern times, the bar for what counts as real journalism is quite low and breaks down when journalists and media organizations won't admit when they are wrong. Mozilla is also a bias organization since Brendan Eich was forced to resign[1] just because he donated his own money to an unfavorable organization. As a gay man, I don't want to live in a world where people are not allowed to express how or why they feel a certain way about a given topic. Mozilla* is not the right organization/company/project to combat the problem of "fake news" or assert that they are.

With the long laundry list of issues with Mozilla, they are not* in any position to take the moral high ground when it comes to the issue at hand (tracking/telemetry) or in the case of being the gatekeeper of the truth.

> can be done even with 3G (video, streaming music, and any website's loading time is more than acceptable at 3G speeds).

I think you forgot how slow 3G was/is. It's around 512KBps. You can stream music on that, but streaming video is a straight nope (480p on youtube wouldn't even be happy with 3G) and even just browsing the web will be a frustratingly slow experience.

4G LTE definitely has the bandwidth to do all those things are reasonable quality/throughput particularly for the resolution & form factor of the device in question, though.
In his other comments, he walks back on his remarks:

> Also, in all fairness to my hated former employer, air travel is still by far the safest form of travel. Even with the shitshow at Boeing, Boeing planes manage to be incredibly safe. I'm really not sure how, but they are.

> And it might be because I grew up around Boeing, but I'd still fly Boeing over Airbus, to be perfectly honest. Airbus makes good planes, but that reliance on computers over pilots just makes me nervous.

> Even the 787, despite all the horrible issues with the initial run, is probably going to be an exceptionally safe plane due to the carbon fiber construction.

So it sounds like much of his commentary is of the "how the sausage is made" nature that is common to the gestation of many (all?) complex products. You probably have nothing to worry about with air travel.

To me, this analysis sounds more about the interference with physical objects (like how 2.4ghz can pass through walls easier than 5ghz). It doesn't seem to be about interference with other radio emissions?

> 30hz to 230hz is much easier to tell the difference than 15khz to 15.2khz if you want to listen to audio tones

That's definitely true for humans, but I don't think it necessarily applies to radio signals in general (though it does make sense at first glance).

I encourage everyone to watch at least one of the many livestreams[1] that Stephen Wolfram did while putting together this release. They changed my perception of Stephen, which I had gotten from the critiques of him that are everywhere on the internet. He is perpetually obsessed with his creation and does not accept mediocrity from his developers; but does so without attacking or belittling anyone, or feeling superior and being condescending, which I thought was his "thing" from what I had read.

He might still have that adolescent ego, and in his blog posts he still comes across as self-obsessed; but in his livestreams he comes across as a decent human.

It sometimes seems that democracy, somewhat paradoxically, trends towards division. The grand projects of times past were generally created by entities where their successor would generally be vested in their success. Be this in the form of religions organizations or non-democratic political entities such as monarchies.

In democracy this kinship frequently does not exist between successive entities, and there is even often an effort to dismantle the works of a previous administration as well as blaming any faults on them. There are also basic democratic political problems. One very myopic, and very common, political argument is of the form: "You want to [do something amazing] while there's [people dying of cancer] [kids starving to death in Africa] [etc] [etc]?!" This argument feels reasonable to most people, and can be used to frame a candidate (who wants to do grand things) as being out of touch. And it's extremely effective. It makes it difficult to spend large amounts of money on things outside of those that can be justified on a very immediate level, such as war.

The space program is probably the greatest project the modern United States has engaged in. And if it had carried on it's likely our species would now today inhabit bodies beyond just this planet. But it was not continued. This [1] is a song from the 70s that was published shortly before Nixon, who had a long standing animosity with JFK since losing a razor thin election to him in 1960, would completely gut the space program - which was very much a reflection of JFK. So determined were his efforts that in 1972, as Apollo 17 was returning to earth during his presidency, he stated "This may be the last time in this century that men will walk on the Moon." He initially even wanted to cancel both the Apollo 16 and 17 missions fearing that a mishap during them could negatively affect his reelection chances. The entire space program emphasizes all of the issues with democracy and grand projects.

I agreed with you until you got to exclusive titles. Despite Sony's past blunders like the PS3, they did good work with exclusive titles, and it's real reason to have a Playstation. Unlike Epic's exclusives, they're not just timed either. Also most if not all of Sony's back library will run on the latest PlayStation because Sony bought Gaikai years ago. Everything said, I still like PCs better than consoles, and Sony has a history of overhyping their hardware. I'd be surprised if it has good performance in 4k let alone 8k.

If we treat microplastics as a symptom of business-as-usual, then they are a marker, and we can think of them as the canary in the coal mine. Entropically, we dug up a bunch of dead stuff and either burned it into the air or refined it into plastic, which we are now mixing into the biosphere at all scales. What other effluents are we dispersing that will have unwanted effects?

Structurally, we concentrate exotic materials and then disperse them. Nothing like that has ever happened at global scale to life before. The economic changes to achieve a system that doesn't make this its default trend are almost unthinkable. That's what I see as the real #4 (or whatever) on the list.
