That would be on my shortlist for among the least important talents for team success.
Well, it seems pretty useful - e.g. it helps make ripgrep fast, it can speed up regex. There's a lot it can make faster. How much faster, I'm not sure.
I think the "chaos" is more akin to the emergent properties of complex systems, where disturbances in one component can propagate in unexpected ways.

"What would happen if..." experimentation doesn't negate the need for requirements. It seeks to actively test whether or not those requirements were adequate in the first place. It also recognizes that no system is static - almost all distributed systems are evolved over long periods of time.

No matter how careful your planning, shit sometimes breaks in the real world in ways you didn't/could not have reasonably anticipated.

I don't doubt that metal is more durable than plastic, but there's some survivor's bias in that statement. We usually think of 70s and 80s appliances being more durable because we see people still using them. The truth is that we've always had a mix of cheaply made vs durable products, and the cheaply made stuff broke years ago and was replaced. We're comparing our cheapest made products of now to the most durably made products of decades ago.

My favourite bit of facadism in London is the Lloyd's building. In 1928 Lloyd's of London built a big wedding cake sort of thing for their headquarters:

Then in 1978 smashed it down and built a giant oil rig, thus summoning Margaret Thatcher to our dimension:

But the wedding cake had a nice bit on the front, so they kept that:

If you walk along Leadenhall Street from the west, on the south side, you're walking past a number of fairly low-rise buildings of various ages, and you don't really see the modern bit. Until you walk past the Lloyd's facade, and look through the front door, and instead of there being an atrium, receptionist, etc, there's a yard with an oil rig in it.

The main points mentioned in the article are:

- our code ended up as entangled mess

- we don't train our newcomers

- we don't use staging environment, and instead we deploy directly into
production

- other teams for configuration management use a deployment tool (a dumb idea
in its own right)

Nothing of this can be held against CFEngine.

The steep learning curve is there only because a newcomer is thrown into
a different paradigm of managing systems, which is a similar situation to
going functional when all you knew before is imperative programming. Other
than that, CFEngine is not really difficult.

You should. Or conversely, you can look at this as having dodged a bullet.

On paper, they were willing to commit to multiple years of a presumptively-six-figure salary to you (seriously: an employment agreement is a big financial deal, even if it's legally "at will" -- there's a lot of money on the table) but pulled out because of some fear of bureaucracy and (maybe) a tax increase? That tells me that the commitment they were thinking of putting on paper wasn't worth, heh, the paper.

That's not a loyal employer, basically. If they're willing to cut corners with the State of Florida they'll do it with their own employees too.

Ask HN: Best Online Business Brokers to Sell Software Business
A trait is like an interface. A struct implementing a trait means it takes on the methods of that interface (but there's more to it, because a trait can have default implementations of of the trait methods).

If you want to express something like "this is a variable that holds something that fulfils this trait", without knowing the _actual_ type it is, that variable effectively has an unknown runtime size. std::io::Read is an interface for reading bytes of some source, like a file or a socket.

This matters because we're talking about a stack frame. So the size needs to be known at compile time.

let a: u64 = 42; // ok, because well known size.

let b: Read = ...; // illegal, because unknown size.

A "trait object" places the object on the heap and has a pointer in its place.

let b: Box<Read> = ... // legal, because pointer is a known size

However it's a bit more complicated, because this syntax allows for dynamic dispatch at runtime using a vtable. So there's a quite big difference between Box<u64> (a 64 bit unsigned integer on the heap) vs Box<Read> (a runtime dispatched lookup via a vtable).

This difference is not obvious at a glance though. Hence the new syntax: Box<dyn Read>.

The objection is not to innovation or originality per se. Nobody is saying that the first example of a concept is always terrible. It's merely almost always terrible. So if you want to produce a good built environment, you are almost always better off doing a humble minor variation on the thousands-years-old beloved tradition than attempting a monument to your own genius.
The free market types I know are generally opposed to requiring tax be included because they think it would hide the "true" cost of the tax from consumers. They seem to like when a consumer is disappointed by the difference between the base and "plus tax" price because they think it will motivate people to try to get sales taxes reduced or eliminated.

I assume you live near Tunnelbanan and/or take the car regularly? Currently I spend about an hour each way on my commute (e-bike Täby -> Danderyd, then subway to T-Centralen), for a trip that GMaps says takes 20mins by car. And the piece of crap doesn't work during the winter. Alternately I could take two buses to Danderyd, for a total of 66 minutes in the absolute best case (never actually happens).

A car is absolutely #1 on my saving-target list, due to that. Oh, and being able to lock stuff inside it. The primary problem is the absolutely awful quality of service (in some areas, at least), not that it is somehow too expensive.

> Sony is the only platform that has "legal hurdles" preventing this?

Not all companies "move fast and break things" in legal matters. We don't know the full circumstances, but Sony may have evaluated the landscape and decided the liabilities weren't worth the potential profits, while Nintendo and Microsoft looked at the landscape and decided that the profits exceeded the liabilities in this case.

It's for the same reason that you find Wells Fargo or Facebook committing transgressions that other banks or social media sites may avoid.
In my experience this is often fueled by people who have the least understanding of their "high bar" criteria: management and HR who never worked at the companies that they think it is really important to hire from or got the degrees they scan for on a resume. The "high bar" mentality often creates mono-cultures, which can be effective, but usually not resilient, and sometimes toxic.

It's weirder than that, you aren't really paying for the items directly from Sony's platform when you play on the PS4, you're buying V-bucks, Fortnite's currency, and that's what you use to buy your items.

Not arguing with this, albeit subjective, logic, just trying to understand what's going on in this instance.

There is a huge assymetry between shipping to and from China. Since China exports so much, those containers often come back empty. In finding something to fill these empty containers on the way back, some smart guy (proabably in China) came up with garbage.

I have many of the same questions too. In industrial robots one of the most important numbers is mean time between failures(MTBF). If the MBTF is too low, that is the robot breakdown or otherwise fails, you spend more on fixing the robot or its mistakes than the cost of the robot itself, the cost of programming it, and the value the robot provides. Cleaning is a huge issue. If they don't clean things properly and someone gets food poisoning this could kill their company and perhaps even the automation of fast food. And if cleaning is time consuming enough it could greatly increase operating costs.

I'm skeptical that this machine adds enough value to justify its costs for the aforementioned reasons, but also because of the decreased flexibility. Other fast food restaurants can introduce new dishes and flavors easily, but if they want to do the same they may need to modify the entire machine. For example, adding two patties instead of one, using differently shaped buns or meat, wraps instead of burgers.

Worse than that, in the states we often build the lines between places where nobody wants to live or get to. A low density slum that only the poor live in on one end, and a nearly dead mall on the other. The few who live near the line find that it doesn't go to where they can find a job so they never use it. Then it dies.

Building a train can make sense. There is a very simple and relatively cheap way to test your route before building rail: put an express bus route on the nearby roads, and give them the same controls emergency vehicles have to change the lights when they come. If the train makes sense this bus route will be always busy and make money. You can even adjust the bus route a few times to study alternate routes. Of course nobody wants to do this as it would kill their pet project.

Very useful. SIMD has a much lower barrier to use (doesn't need graphics drivers, GPGPU frameworks etc., almost universally available and fallbacks are easily implemented) and is much easier to target (same language, same toolchain, same memory model).

Also notice that the execution model of GPUs and CPUs is quite different. You need a far larger "breadth" of execution to efficiently use a GPU, compared to a CPU.

Beauty has bastardized into branding. The building is a sculpture that needs to project the values of the patron. That's why most modern buildings look futuristic, because most institutions regard themselves as forward thinking. Or buildings look "fun" or "interesting" or "special", or whatever trait the patron thinks defines his identity.

Robustness isn't required anymore either, since building cost is amortized over the duration during which the typical investor expects a ROI, a generation or so. The practical result is new buildings that are no longer build to last indefinitely.

Mesons have a wide variety. Some are quarks plus different anti-quarks (e.g. up + anti-down). Neutral mesons are not just quarks plus their anti-quarks, they are usually quantum superpositions of multiple quark/anti-quark pairs. For example, the pi-0 meson is a superposition of up + anti-up minus down + anti-down, all divided by the square root of 2 (quantum mechanics is weird). However, it gets even more complicated when spin comes into play, an up + anti-down meson could be a charged pion with 0 spin and a mass of 139 MeV or it could be a rho meson with a spin of 1 and a mass of 775 MeV.
> A better question is why haven't cities required sufficient housing near jobs

Because to require a particular level of housing near jobs would require a prohibition on offering jobs without developing additional housing, in effect limiting jobs. Even if local governments are given the power to do that, politically, citizens demand that politicians do what they can to encourage job creation, not limit it by some other constraint.
