1) There are a few types:
- Working in the city center --> Walking mainly.
- Working outside of the city --> Cars/bus

The city that has banned the cars is the city centre, but is a round island, so in 10-25 min walk, there are parking slots, where you can drive from.

2) Shopping trolley, instead of buying a lot one day, you ended that each day you pick up a few things. (And this is great, 15 min day walking)

3) All the emergency services can go to the city centre, so cars are banned, but if you have an event or emergency cars can get into, here is the common sense rule.

And there is a benefit here, kids are in the street, and due a lot of kids in the street, that moves the street from unsafe, to full of #know people, that make things super safe.
There isn't really much political will to mitigate car dependency and curb sprawl, but if hypothetically there were, it would still take half a century of concerted effort to reshape our cities into something a little less dystopian, and in that meantime autonomous vehicles would be very effective for shuttling people between their homes and major transportation hubs, because busses on feeder routes just don't work very well out in the burbs.

Once I turned around a startup from about to go under to s profitable one. We restructured every piece of the value chain, but not without resistance from the founder/owner. Every suggestion I made was met with “I tried it and it did not work.” In reality she did not try, she intended but backed off when the other party pushed back.

In essence we took control over cash by:
1. raising prices significantly
2. Introducing differentiated product and two tiered pricing
3. Switched product production from prepaid to 45 days AP.
.....
N. Restructured relationship with distributors

All these actions produced huge negative working capital. Instead of financing operations at an insane % rate, which technically was killing the business the company paid off all the debts and was spewing cash.

Cash Is King
Is that urban planning or suburban planning? Are we talking about better planned (more walkable) inner cities, or are we talkingt about a long term shift in what people wants, such as people not wanting a private back yard?

Because outside of cities, as long as people have detatched homes on reasonably sized lots, getting around requires a car. There will simply not be the density needed for efficient public transportation.

While I might agree that the idea of large suburbs with detatched homes is probably not very sustainable, I don't see how they aren't here to stay (together with the cars required to live in them)
It turns out, there's a name for this (which I learned in a HN comment): resource curse.

One theory being that, essentially, legal controls and enforcement are expanded with economic activity. But a sudden surge in resources (e.g. discovery or exploitation) exceeds the existing system's ability to control corruption, and it's very hard to steer a cash-rich system back to good governance after this happens.

Not my startup but worked for one until they pivoted. We had a photographer platform (https://picr.com) competing with Thumbtack (except our photographers were to be paid higher instead of a bid to the bottom.

Everything seemed right. We had the right market (Portland, OR), with a beautiful design and great customer experience. We managed to get roughly 100 photographers on board but the customers never came. After a year or so, Picr ended up pivoting to more of a photographer platform than a AirBnb/Thumbtack alternative. Most of the team was let go and only a few devs stayed.

Lesson learned: Building a two sided market is hard.
I’m not so sure. How much land would you need to be completely isolated, no other houses in sight? A square mile? More if you live high on a hill (which many people would like to do).

Wikipedia says the area of the USA is only 3,794,100 square miles, so there aren’t very many square-mile patches to hand out compared to the size of the population.
> That's not the solution if still you plan on having every person and their car move around. Maintaining the infrastructure for cars on the surface is already expensive and inefficient. Suddenly we can do it better or cheaper by multiplying it underground? You won't get rid of any of today's problems except one: drivers will be able to move from one side of a city and create a traffic jam on the other in no time.

That's not quite true: by completely splitting car traffic and pedestrian traffic on different levels, you can create a city which is much denser and easier to walk because you don't need large car streets, and at the bottom you don't need pedestrian affordances alongside car traffic. Plus by banning car traffic far away you disincensise car traffic within the city: it's usually easier to walk, bike or take public transport than go to the bottom, get into your car, drive, park over there and go back up.

Louvain la Neuve works on that model, the city is built on a huge concrete slab and entirely pedestrian, with car traffic and parkings underslab.
Makes you wonder why smaller family or close-friends type social networks don't work.

Because they are run by for profit companies, operating in a capitalistic framework.

That is one of the core pillars of free software as envisioned by Stallman - software that can truly serve the needs of the people, because it is not subject to those pressures.

A world where your girlfriend’s family could painlessly deploy their own such service for just a few users and not have to worry about a company shutting it down whenever they feel like it would be wonderful.

>So he called up Amazon and said, “Hey, this is Steve Jobs,” ...

And "Amazon" replied:

"Hello, Steve, my name is Adrian, I will be happy to help you."

Seriously, it is not like he cold called "Amazon", he already knew whom to contact exactly, had already met the relevant executive (or the CEO) personally many times, etc., etc. , and the actual deal was probably closed after several weeks of meetings, a formal legal review and what not.
Cars are the ultimate tragedy of the commons. People want to use cars but at the same time don’t want the negative externalities caused by everyone else using cars too – congestion, noise, pollution, road surface erosion. Because that selfish individualistic viewpoint gets us nowhere, a coordinated approach is needed.
I’ve found virtually every vendor I deal with starts abusing their power until they receive an RFP that lets them know they’re in competition. The cloud salespeople I’ve met are no different.
reliably brings home a week worth of groceries, drives me 2hrs to meet family, and occasionally delivers tools and materials to various points. All that on the cheap, and with easily calculable costs

All the talk of banning cars seems to come from people so privileged that other people invisibly provide all the services of the road network to them, delivering their stuff and so on. I mean if a person’s entire life is based on Netflix and Amazon and Uber Eats in an apartment full of stuff that just magically appeared sure they don’t need a car, and no one is forcing them to buy one. But they are so vocal that everyone who hasn’t chosen that lifestyle should be penalised, and they can’t even clearly articulate the alternatives. An hour outside London “public transport” is one bus in the morning and another in the afternoon. But yeah, let’s all get self-driving trams or something on every B-road...

Many cities in the US have banned cars from a significant number of Downtown Streets. We call them skyways for the most part, though sometimes they are underground. It works well, keeps cars out of the way of people. It also makes for a nice environment to walk around.

Our zoning is such that those streets close at night, and I wouldn't recommend them in the late hours before they are officially closed.

Suggestion: Have one on ones with each of them, regularly, and have them speak (it's not you speaking during this meeting) to explain what they're doing, they will tell you what problems they face.

Speak after them to answer within short timeframe, and most importantly follow up to help them, frequently and in the long term, with thei problem they expressed.

I hope it will work for you.
There is a pedestrian city in my province (Córdoba, Argentina) called La Cumbrecita. You leave your car in the entrance to the city in a parking lot and you can walk the entire town.

First time I visit there made me wonder why not all towns aren't pedestrian like this. I mean most towns have nice sidewalks and are walkable but why not just banning cars. In addition to having less noise I can imagine plenty of other benefits.

> [La Cumbrecita] is completely pedestrian and reminiscent of the small German towns of the fifteenth century. One can hike up through the town (and then down) to the waterfall, a truly paradisiacal experience.

CLA Assistant: Let people easily sign contributor agreements before allowing PRs
Exactly correct (and much better put than I did). I remember, vividly when the "one-click" patent came out, and honestly, it seemed completely ludicrous. All of the people I knew in the valley at the time openly mocked it. It was exactly the sort of thing that any intelligent designer would have come up with, given the presence of cookies (which were at least a bit innovative, but Netscape had provided a royalty-free license to the patent). "One-Click" purchasing is precisely the idiocy that we think of, when we think of Patent abuse.

So, when Apple actually paid money to Amazon, what occurred to me at the time, was that Apple had in a single stroke both added some legitimacy to the Patent, and probably got a discount on the deal because they were the initial customer. It's unclear whether the one-click behavior on IOS made use of any the processes described in the 1-click patent, but, at the very least, it didn't hurt that Apple had it in their back pocket.

All in all I think it was a win-win scenario for both parties.
Reddit is already a site for moderate users and edgelords. Subscribe to The_Donald and ImGoingToHellForThis for edgelorderie, avoid them for a moderate experience.

I know somebody that is in the explicit business (as in this is their profession) of getting tech companies to aggressively add stronger moderation to their platforms. It's an objective with some admirable aims, but what I will never understand is how the reddit solution isn't already considered to be the perfect one. I literally read 0 The_Donald content, ever, and yet I see its existence referenced pretty frequently as "proof" of why reddit is actually run by Trump sympathizers. I am not exposed to it at all, I don't see what the issue is. Working exactly as intended.

The moderation culture varies so incredibly between subreddits, you really can find things that are perfectly suited for your tolerances. If you can't, then you can make a subreddit for the same type of content, where the distinguishing factor is that the culture of moderation is different from the one that didn't suit your taste.

There's a another twist in here when you have organizations that use "matrix" management, where you not only do you have line managers (like the role described in the medium article), but you _also_ have project managers (PMP's) and program managers.

A good line manager will shield his folks from project-management bullshit mind-games. Giving PMP's direct access to your people is a recipe for stressing out everyone involved. Unfortunately, that is becoming more and more normal these days as the manager-to-contributor ratio converges to or exceeds one.

most security professionals have decided to ignore that problem and pretend that all certs have ever needed to do is secure the wire

If you want to blame someone, blame the original designers of the current system, who decided certificates had to be a one-size-fits-all solution for both encryption and identity. Also, blame the years and years and years during which people on sites like HN condescendingly insisted that identity was the important part of TLS/SSL, and who more or less said you'd be better off unencrypted than encrypted without ultra-mega-hyper-octuple-verified identity.

The industry has basically given up on the idea that there is some way to establish trust on first visit. Which is nuts, because we take it for granted in real life that we can just walk into a brick and mortar store and conduct business without getting mugged.

In real life it's difficult and expensive for me to rent a brick-and-mortar storefront, cover it with the branding and logos of a trusted company, stock it with real-looking products and employees in uniforms, etc. On the web, it takes five minutes and costs little or no money to produce a good-enough imitation of a trusted company's site. Any attempt to analogize between them will fail because of how much lower the barrier is online. Any attempt to say that it's easy in real life, so it ought to be easy online is based on missing this fundamental fact.

Also, we live in an age where it's profitable to cold-call people on the phone and say "I'm the tax authority and you owe money, buy $500 worth of iTunes gift cards and send them to this address", and where the majority of calls that come to my phone use spoofed caller ID to try to scam me.

"Trust on first visit" is really a monstrously hard problem, and I think you're underestimating that.
It is as big if not larger than After Effects - it's an entire VFX pipeline: servers as render nodes, as compositor nodes, and so on...

In perl, you can also make hashes ‘const’ at any time, so accesses to non-existent keys will throw an error. This is also a great way to prevent dumb code typos in hash key names.
Right out of school, another person and I had a startup building a managed VoIP solution.

We didn't start selling early enough, and underestimated the amount of time closing our first sale would take. That lead to my business partner taking another job to make ends meet, and not able to meet obligations to our company. Since he was managing the relationships and I was doing the tech, I basically was left trying to manage the relationships from scratch, many of whom weren't interested anymore. I very quickly ran out of money before we could sign a contract.

Lessons (probably too many to list):
1. B2B sales is a lot harder than the tech. Make sure you have the runway to compensate for learning how to sell.
2. Make sure your business partner(s) are as committed as you are.
3. Don't use your own money, or at least have multiple sources of income.
4. Have a good advisor. I feel like if I had someone I could have asked questions to, I would have been more successful, or never would have taken the risk.
5. Probably most importantly, don't look at it as a failure, but a learning experience. I was pretty depressed when everything came crashing down, but I learned later that it was a valuable experience that put me ahead of a lot of other people just due to the sheer amount of work it was.

Where I grew up (Huntsville, Alabama), if you saw a pedestrian or cyclist around town you would assume they are homeless. After living in SF and Montreal and traveling in Europe, I can't see myself going back to a "car-first" city. Which sucks because that's pretty much all the US offers.
Yeah, I'm sure they would be able to deploy the service, have it secure and updated, having apps up to date on their new devices. Or maybe that takes time and effort, and people need to pay their bills.
I buy the theory that he just wanted to have fun ?
One I joined failed due to:

1 - Inability to convert unpaid customers to paid. (And a focus on the wrong vanity metrics)

2 - Poor analytics which caused number 1. (The AI didn’t work)

3 - Weak governance. (Too much money too early, and a paradoxically bad founder/funder relationship)

4 - Excessivr nepotism, side projects and conflicts of interest.

This gave me a checklist to look for in companies I subsequently interviewed at.

Show HN: A Functional and Reactive Framework for Node Back-Ends
Hey all,

I couldn't find a framework that embraces FRP/RxJS for Node yet, like we have Cycle.js for the front-end [1]. Thus, I've been toying with the idea of working out what this could look like myself for a while. The result is Molen:

https://www.npmjs.com/package/molen

The main goal of this project is to find out whether it makes sense to give Observables such a central role in Node applications and, if so, what API would be most comfortable. So far, I think it has potential, but I'd like to invite everyone who is enthusiastic about FRP or RxJS to give it a look and perhaps even a try, and to let me know what you think of the current API.

(And to pre-empt some criticism: when I use the term FRP I refer to reactive programming using functional methods, not DCTP. [3])

I agree completely on Elon; that’s probably the same fate other tech greats will be granted as well.

While Peterson’s most basic premise to “fight against nihilism”, is respectable I don’t think he is philosophically well-equipped enough to have the same lasting effect as Nietzsche—if you listen to his arguments it’s clear that he’s quite ignorant of a whole swath of philosophical developments that have occurred in the past few decades. His arguments are not sophisticated. Someone with a basic education in the humanities can craft them just as easily. His whining about the death of individuality is also shallow—he doesn’t even realize the very shape of the concept of induiviudality itself has changed over time. He’s praying for the ressurection if old concepts, which is a method the ignores the particularités and needs of our own historical situation. Part of this could be a result of his trying to reach a wide audience, part of it could be his lack of capability, idk. At any rate, even though Nietzsche has an aphorism about writing for your readers it’s clear he himself didn’t do so, and his reknown partly stems from the uniqueness of his style, which is impeccable. In this regard Peterson doesn’t hold a candle to Nietzsche. Of course he may still be remembered, given he’s speaking for a different era, but idk, lacking argumentative or stylistic ingenuity typically doesn’t net you a spot in the hall of fame.
