This is one of those questions which I actually think requires empirical investigation.

Fortunately, Jonathan Haidt has excellent papers on the historical formation of moral systems in culture collision events, and the argument he has is that there are six different types of dichotomies moral taxonomies in societies exhibit, each driven by various kinds of evolutionary challenges individual societies faced. (https://poseidon01.ssrn.com/delivery.php?ID=3680010931100921...)

I think the conclusion that societies are built primarily on cooperative rather than antisocial behaviour is a picture based mostly in game theoretic analyses (per that wonderful webpage, The Evolution of Trust) - but empirically societies do really vary in how harshly they punish or value non-cooperative behaviour, which I don't think game theory is sufficient to explain. Some societies hold that maximising personal utility over group utility is a social norm, though usually personal doesn't mean individual but individual and smaller subgroup (such as family), so they're not likely to view non-cooperative behaviour as problematic - these societies tend to be not influenced as much by the fairness/cheating dichotomy but are high on the care/neglect and loyalty/betrayal dichotomy.
I also wonder why that number. But as others said, it's a pretty famous number all by itself so it makes sense for there to be some notice paid to that- if there were no hyperlink I would've thought it's weird and maybe someone made a mistake.
I don't trust nor agree with Facebook but I can see the appeal.

I recently sold a synth on its Marketplace which I had never used before. Here in Mexico its extremely popular. If Facebook starts using Libra for payments and escrow without having to pay credit card or bank transfer fees it would make it much more popular than Bitcoin. At least for small transactions.

This would have to have been at Facebook. Rachel and I worked in close physical proximity for quite a while, and as it happens, I was a major Tejava consumer (but not an actor in this particular incident). For years, Facebook routinely maintained ample Tejava supplies, but then suddenly the 0-6 bottles per day stocking became the new norm. Many here fault the participants for making the commons tragic; my take remains that someone made a terrible decision to limit supply (probably due to cost), and it turns out that several of us employees countered with negative sentiment that made it a net loss for the company. I did not begrudge those who beat me to the inadequate supply, but I did begrudge the shortage.

As noted by other commentors, retail investors are much better off these days because of tightened bid/ask spreads.

After working in HFT for nearly 10 years I've learned the firms that do the best do so by proving value to the market. Through competition with one another, retail investors are much better off by getting better prices from market makers who do a better job.

Of course that would itself be incredibly expensive. Roughly 1/4 the cost of all the roads in a city is a tremendously large amount of asphalt to maintain exclusively for buses.

That's an entirely fair question, and in a lot of piano auditions at least in my experience memorization is required.

Take a look at the sheet music for the Stockhausen Klavierstucke mentioned in the article and you can see why this would be helpful.

A very important skill I learned is to catch myself spending too much time solving the same problem head on, fire an interrupt, step back and rethink. In most of the cases, approaching the problem from a different angle, reformulating it, or just saying "Fuck it.

> I'd argue that feature set (transactions, ACID, etc) are a bigger differentiator because they drive/change application development

Handling atomic transactions or ACID on a single computer is a completely different problem from dealing with them across multiple, and still a different problem from dealing with them across datacenters. I'd argue that the size of your data is the first question you need to ask, only then you can figure out if you need/desire these features.

> once your data does not fit on one computer/harddrive you need to start figuring out a way for multiple to coordinate

Going from one computer to two generally more than doubles the complexity of the system. But when done right, going from two computers to two hundred can be easy. However, going from two hundred (in a single datacenter) to ~two thousand (across multiple datacenters) brings its own unique set of challenges.

Picking the database for an app is one of the biggest tech decisions any team can make, certainly more important than the underlying OS, and even potentially more important than choosing a predominant programming language. Even when starting a tiny startup with no initial customers, considering how big about the absolute max you think you your data can grow, and picking a database that can grow with you can save you huge headaches down the road.

Case Study: I started a company on Python 2.7 (fine, but not enlightened decision), a fork of Django that supported NoSQL (bad decision), and an underlying NoSQL database that scaled with no configuration (great decision). In the first year, the database had around a gigabyte of data, so NoSQL was definitely overkill. But now, it's over 100 Terabytes, with auto replication making it much larger than that. Changing the Django middleware or even the Python language to 3.x will be difficult, but not impossible. Moving the database is far more terrifying, a non-starter.

Its discovery is quite legendary.

It was the first multiplication algorithm faster than long multiplication known to humans. Before 1960, few people thought it was possible to do it faster than O(n^2). Even one of the best mathematician in the 20th century, Kolmogorov, believed the long multiplication is probably asymptotically optimal in 1955, and asked people to try proving this conjecture in a 1960 conference. And within a week, his student Karatsuba found this algorithm. It's also one of the earliest divide-and-conquer algorithms discovered in computer science. Since then, faster and faster algorithms have been discovered.

Although in practice, the ALU itself is almost never the bottleneck of computation on a modern computer. The setup cost of these algorithms is often greater, making them only useful for bignum (Karatsuba is only faster for number longer than a few hundreds of decimal digits?) It also explains why faster algorithms haven't been discovered in the last 2000 years.

Exactly, WeWork is turning into a normal business with competition. I think of them as similar to a hotel chain. Hotel chains basically own or lease real estate that they rent out on a per night basis to individuals. The reason the hotel business has multinationals owning large amounts of hotels world wide is because that kind of scale provides certain benefits in terms of operational cost, brand recognition, etc.

WeWork bootstrapped a multinational with hundreds of locations world wide using investor money and are now serving hundreds of thousands of users that apparently like them enough to pay a premium for using their space. So far so good. But it's something that others can copy and there are a lot of smaller and bigger competitors starting to offer similar services that are showing healthy growth.

The premise of WeWork's valuation is that it can continue to charge a premium because of their scale. However, if other competitors emerge, it becomes exactly like the hotel business and they'll be competing on price and quality. Given enough competing spaces, their customers will simply flock to the ones with the best price and offering.

That is going to limit the ROI for investors and probably is causing them to have second thoughts about dumping billions in it. Hence the IPO withdrawal.
I've done the London commute for 6 years now.

My solution : work out flexible hours with my employer. If I have the stand-up at 11 I can jump in the underground at 9:30, after the worst of the rush is done. Likewise in the evening, work until the worst of the rush is done.

My SO solution: live in the city, work on the outskirts. The commute is effectively against the traffic. Can get a seat and plenty of space at 8:30, top of the rush hour.

There are some solutions but I'm not sure that they scale, though.
Where I live we have some squares in town that are pedestrian only except for buses. Buses move through at speeds below 10 km/h. I can't recall there has been an accident there.
As presented, this isn’t a thorny issue.

Forcing a company to run any ad based on nothing more than who pays the most money is not only a terrible idea, but effectively compelled speech.

“Free speech” doesn’t include a guarantee that someone will publish it for you. It just means no one can stop you from publishing it.

The public airwaves argument is the only argument that makes any sense at all, but it’s a weak one in my opinion; and that’s now how it currently works in practice.
Then how is it that businesses always seem to do better after city streets around them are pedestrianised?

For me 1/4 and 3/4 is the wrong balance, as it's too car friendly and makes no mention of trams and light rail.
I think it's less an issue of stealing existing customers than it is filling the vacuum that would have been filled by a massively expanding WeWork. If WeWork has indeed tapped into a growth market in their flexible term leasing & quality environments, then competitors will have an opportunity to soak up demand that might otherwise have gone to the expanding WeWork offerings.

I think you're generally right about them not losing customers, but they may lose some: Short leases mean ease of mobility, so if a competitor offers similar quality at a lower price, or if you've outgrown your current We space and would need to move into a larger one anyway, you might be enticed to switch. However, that sort of competition would apply with or without WeWork's current issues.

Not exactly. I rather dislike XMPP's design, and what I'd like to see is something not only decentralized (relying at most on a DHT seed), but supporting group chats with trivially-expirable keys. My limited exposure to OTR suggests it only reliably supports one-on-one exchanges.
Yep, using VPNs makes the organisation lazy in security. But insecure apps in a "company internal network" is still not ok IMO. In the exceptional cases that you can't fix, the way to go is separate dedicated environments for the risky apps, and disconnected from central services.
You can get small commercial vehicles/delivery trucks down most of the streets in Zurich.

Cars are also expected to make way for emergency vehicles, and as the other poster mentioned, emergency can use the rail lane when they need to.

Drivers are expected to keep crosswalks open at all times. Pedestrians at crosswalks also have the right of way, and it's extensively enforced. A lot of the junctions also have cameras - it's on you if you get stuck in one after the signals change, and the fines aren't cheap.

Maaaaaybe. I see the CDNs bringing on compute & durablish storage at the edge. And id buy the argument theyre positioning themselves for the next round of “cloud” ala Lambda + DynamoDB.

But I strongly object to the capital characterization. Akamai, the gorilla in the CDN room, to looks to have capital expenditures of $200M or so for hardware/colo/etc. Cloudflare was spending $20-30M IIRC. Conversely Amazon “Cash capital expenditures were $6.7 billion, $10.1 billion, and $11.3 billion in 2016, 2017, and 2018, which primarily reflect additional capacity to support our fulfillment operations and additional investments in support of continued business growth in technology infrastructure (the majority of which is to support AWS).”

Money alone doesnt buy success but the CDN guys dont seem to showing up to the game yet. As youve noted I dont really see anyone else on the trajectory to general competition with the big three.

>That is going to limit the ROI for investors and probably is causing them to have second thoughts about dumping billions in it.

Precisely. Apart from corporate governance, the problem was never really the business fundamentals since with careful oversight they really should be able to flip the switch from massive growth to profitability. The major issue with that is investors put their money in at 20x revenue premised on growth when it now looks like it's a more traditional 4x revenue business, at least for the near term.

*>they don't have free coffee or a gourmet selection of tea like WeWork."

That's the thing, just like "free" breakfast or coffee at hotels, there's always a cost baked into the price. But there's something to be said for the psychology as an "all in" price rather than nickel-and-dime, or having to brew your own coffee. Though for $100 a month, I'll absolutely brew my own coffee.
They're only centralized because free markets tend to favor centralization. Should the big mining operations be shut down, it would become instantly profitable for smaller miners to switch on again
But what’s the difference between in stability between an autoscaling+autohealing VM running a 100% kernel-mode application, and a VM hosting a 100% user-mode process (presumably under an init daemon that will autoheal it)?

And does “fragmenting kernel memory” mean anything, if you preallocate a memory arena in your kernel driver (taking “everything the base kernel isn’t using”, like a VM memory-balloon driver), and then plop a library like jemalloc into the kernel to turn the arena into your driver’s shiny new in-kernel heap? You’re not messing with the kernel’s own allocation tables, any more than a KVM VM’s TLB interfere’s with the dom0 kernel’s TLB.

See also: capability-based operating systems (like Microsoft’s ill-fated Midori), where there’s no such thing as a per-process address space, just one big shared heap where processes can touch any physical memory, but only through handles they own and cannot forge. If your OS has exactly one process anyway, you don’t even need the capabilities. (This also being how managed-runtime unikernels like Erlang-on-Xen work.)

Also, another example of what I’m talking about re: benefits of this approach. would you rather that a VM operating as an iSCSI disk server ran as a userland iSCSI daemon managing kernel block devices; or—as it is currently—as an entirely in-kernel daemon that can manage and serve block devices with no context switches or memory copies required?
> Short leases mean ease of mobility, so if a competitor offers similar quality at a lower price, or if you've outgrown your current We space and would need to move into a larger one anyway, you might be enticed to switch.

Most articles about WeWork ignore half of its business model. The first part, which is heavily discussed, is acquiring long term leases, and then leasing out short term rentals. If this was their entire company, it would clearly fail as they're basically absorbing the risk of any long term risk of their tenants.

But the other component of WeWork's business is to create vibrant work environments that people want to work in. They have excelled at this, bringing the silicon valley relaxed low formality tech vibe to every city across the planet. The vast majority of office workers still work in stuffy environments, that are uninspired, formal, and depressing. Bloggers and startups may have created WeWork, but now employees at law firms, finance companies, and accounting agencies are starting to demand a similar environment. Having good offices is becoming important to hiring the best talent. Sure WeWork has competitors and inspired corporations can always build their own WeWork-esq office space, but assuming this trend continues, WeWork has a ton of headroom.
