Largely flexibility - you can build consists that contain multiple driver cars and still allow passengers to move between them, and then you can split them up and rearrange them without having to remove and reattach separate cars first. BART actually switched from angled front cars to flat front ones when they increased their fleet size, and converted a bunch of the angled ones (some were kept for effectively PR reasons). But the alternative is that you're losing space, since the maximum length of a car is determined by the track geometry and clearance of the system. Anything other than a flat fronted car is reducing volume available for passengers.

IMHO I did enough coding, even wrote papers, just to find recruiters didn't eve bother to read the titles.

Your reply makes me thought about a community certification test, taxonomy or classification of company profiles. Which as far as I know it doesn't exists.

I think it's similar to what is going on in an adult's brain as they watch other people play sports; only a bit more sophisticated as your child likely plays the same game competitively and is gleaning strategy and insight, rather than drinking beer and cheering for a colour.

We used to have the greatest minds of our generation working on HFT and ad technology, now they’re working on tech that enables our Orwellian watchers. It’s a scary future we venture into.
I enjoyed that post when it first came out - now it has left high school !
The implication that “actually, it’s all the lib’s fault” is absurd.

This is assuming oil is still valuable in the future in the face of increasing pollution standards, potential carbon taxes, and the rise of cheaper renewable energy production.
It’s used for bio-diesel. The cars that run on it are sold as green, but by burning the rainforest to make enough palm oil, the cars that run on it are instead the least green.
Pick a random non-trivial line of code of HIS on-line software projects repository and ask him to explain it. As simple as that.
The headline doesn't really fit the article. Here's the bit that explains it: "Imports of biodiesel to the United States surged from near zero to more than 100 million gallons a month. As fuel markets snatched up every ounce of domestic soy oil to meet the American fuel mandate, the food industry also replaced the soy it had used with something cheaper and just as good: palm oil, largely from Malaysia and Indonesia, which are the sources of nearly 90 percent of the global supply."

Biodiesel was supposed to be good. It can be made out of a variety of vegetable and animal oils. I don't think they talked about palm oil in particular.

No way. I recently put together an off-shore dev team. We interviewed folks in Mexico, Poland, the Philippines, China, and India. The quality differed and the price differed, but not by huge amounts. No one charged $15/hr for a decent developer. $30-50/hr was the norm.
what buzzword, the cleaner the process the easier it is to produce anywhere, the easier it is to use solar instead of fossile fuel. I just forgot the actual name: tetrachlorosilane when I typed my first comment

To avoid this http://www.washingtonpost.com/wp-dyn/content/article/2008/03...
I think there is an essential core of an idea in "MVC" which sustains across all of its interpretations/implementations.

The core idea is: you want to keep a firm separation between UI code (view) and object-oriented business logic (model).

Other objects will need to reuse your model as your application grows; UI code will clutter that reuse. For example, your business logic should return an array of Customers, not an array of UI labels. The business logic shouldn't directly refer to UI code at all.

In addition, you'll probably want to reuse some of your UI code in multiple contexts. A fancy resizable scrollable table shouldn't directly refer to Customers, because you might also want to use it to display a list of Purchases.

But if the business logic shouldn't directly refer to UI code, and UI code shouldn't directly refer to business logic, then you'll need some code to bridge the gap. That's the controller.

But this idea still leaves a great deal open to interpretation. How much work should the controller do, vs. pushing that work to the model or the view code? What's "business logic" as opposed to "view logic"? Should the controller code be a single object? Is your view logic complicated enough (and reusable enough) to justify separating it out into another object (a "view model")? If you never write any reusable view code, do you even have/need MVC? All of these questions are unresolved by "MVC."

Because the technical truth is only part of the equation.

The right decision almost always boils down to a combination of experts, finances, end users, over all strategy, corporate culture and realism.

The variables variate in importance, but the one thing you can be consistently sure of, is that experts over value theirs.

On top of that, decision making is only a small part of management. The majority of it is spend on politics, motivation and issues/conflict resolution.
Have you ever been to Japan, Germany, etc? Cities there are shaped completely differently to cities here. The article uses the Vienna Metro as an example of what not to do, and in a way it is. But it’s that way because Vienna is almost entirely low density sprawl, with homes sitting on a quarter of an acre or so. The whole DC metro area is shaped that way, and that drove the structure of Metro. The DC Metro area has 6 million people, about the same size as the Berlin metro area. But 3.7 million Berliners live in the city itself, while just 700,000 Washingtonians do. Berlin and DC are similar of a similar density, but almost all the DC Metro population lives out in the low density suburbs. A lot of the jobs are out there too. A lot of tech jobs are in Reston and Dulles, 20-25 miles west of DC. Do you know what’s 20 miles west of Berlin? Nothing, it’s farm land. The kins of transportation network a city like DC, where the population and jobs are spread out among low density suburbs, and a city like Berlin, with population and jobs concentrated in the core city, needs are completely different.

Mostly risk of death reasons. Solar and battery are not high on my list of lifestyle and risk components any more than a car parked outside or plants are.

Maybe you live in a much higher crime risk area. I know (for instance) honey hives in NZ are being predated by gangs so I can believe there are portable high theft risk things in rural settings. But I'm really unsure a Tesla battery rig is one.

I've had plants stolen. I still maintain my garden..

We stayed here: Silverback Lodge > https://www.tripadvisor.com/Hotel_Review-g319722-d2045553-Re... - and set up our trekking through the hotel. They only allow small groups at a time and limited number of treks (for the gorillas to not be overwhelmed) so its best to just book through the hotel.

A few other things to keep in mind:

- Bwindi Impenetrable National Park is quite far from the main airport. So I'd suggest staying near the airport for the night and leaving the next morning. Although even if you do that you might not get in till pretty late at night, and its really remote so hard to get directions. Try to have whatever hotel you stay at arrange transportation, I wouldn't suggest driving yourself.

- As the name implies - Bwindi "Impenetrable" National Park - the hike can be pretty strenuous. The guide will scout out where the gorillas are before you leave but it depends where they are - can easily be a 3hr+ hike through steep inclines so prepare for that.

- One option you can do is to use a porter, we did just because of how much camera equipment I had. Although even if I didn't have much stuff it was still nice to have stuff.

If anyone else has any specific questions happy to answer them here as well.
I say it because I was surprised at the offense some people took to the idea!
Just out of interest- what questions are your peers are not asking?

The Economist is basically that happens when you stick your finger in the air and want to write down what the "consensus" opinion is. It's neither insightful, nor surprising. In a way, it is the most boring magazine there is.
That means they do meaningless unnecessary wrapping too. It is even more ridiculous for a weak-typed language.

The only point of a Monad is that in a lazy language it desugars into an implicit nested functions, which guarantees the order of evaluation.

The monadic code, then, could be generalized over >>=, >> and return, and given that, specialized instances of a Monad class could be made, like Maybe, ST and what not.

The only meaning in performing these steps is to establish a guaranteed order of evaluation (via implicit nesting of functions) for serialized abstractions.

But that is ok, most of Javascript coders never studied CS fundamentals or comparative PL.
Would you give up more to ensure your children don’t grow up in a dystopian nightmare? What if the necessary amount is 60% of your income? 90%?

Ask HN: How to do freelance work that is reclaimable?
Most of the projects I see, their coding depends on the outsourced company it started. I would like go into consultancy business but when things go side ways and it comes time to leave my customer, I would want them to remain happy.

Here, I wonder if how other companies are willing to take over the existing code? What should I do best to make transition easier for the project itself for encouragement of new team taking over?

Thank you for thoughts.

The option monad is literally isomorphic to maybe. It 100% follows the definition of a monad and is an instance of the monad type class in Cats and Scalaz.

Many algebraic data types are monads. I’m not sure why you think that is a contradiction.
On the other hand, there’s a dangerous belief that emissions are something corporations do for their own greedy purposes; if they can be curtailed, ordinary people could go about their lives in peace. This is backwards. It is consumer preferences - to drive an SUV to a detached house in suburbia, to fly home for Thanksgiving, to eat meat, etc. which inherently require massive amounts of energy. Polluting corporations happen to be the mechanism for fulfilling these demands under capitalism. If we expressed our preferences by voting instead of spending, it could just as easily be the state doing the polluting.

To really address the issue requires disempowering and disenfranchising average people, denying us our customary and preferred lifestyles. This is a monumentally difficult thing to do in a system that requires the consent of the governed. Giving up your lifestyle vs. voting to give up your lifestyle (even if indirectly, by crippling the companies that provide its constituent parts) are not too different.
This is a phenomenal explanation! I especially like the context around where these concepts come from.

Another great treatment of this is the chapter on monads in Functional Programming in Scala.
Are there places in Europe and Asia like this? Syracuse doesn’t have a transit network because nobody lives in Syracuse, they live in the sprawl around it.

What shocked me about my recent trips abroad (to Munich and Tokyo) was that those cities were completely different. You drive a bit out of Munich and the city just ends and becomea farm land. Even with Tokyo there ia farmland between the city and Narita. In the US, it’a sprawl in every direction, and most of the population lives in that sprawl, and not in the city.

The problem with algae derived oil is the algae requires lots of fertilizer. We need to grow azolla to use as a feedstock. It is remarkably efficient at pulling both nitrogen and carbon from the atmosphere, able to double in mass every 2-3 days in ideal conditions with minimal inputs other than sunlight and water. Makes a fairly good fertilizer, too.
I didn't criticize the selection of content and the depth thereof. These aspects are well done.
t's not the same technology. Job page doesn't have RSS. It will be hard to read and get an update from different agencies/company career page.
In the limit, you build roads too small for cars, like in the old walled medieval cities in europe. They are in general great places to walk and terrible places to drive.

In the other limit, you build like e.g. Detroit suburbs, where it's essentially impossible to do anything on foot, ever.

If you have to choose which one to be more like, curvy narrow roads are the way to go if you care about pedestrians.

Add to this the fact that, if you provide space for cars, they will take it up: adding lanes / width / parking increases car usage to a greater extent than the space added, such that you end up drawing more congestion to the area than before it was improved.

0. Have more conversations with more groups of people.

1. Notice the things that make you laugh or you find witty in conversations. Keep a journal if necessary.

2. Steal liberally.* If the comments are highly situational, think of ways to generalize, or imagine similar situations where you could use similar material.*

3. Focus on people's reactions when you tell those stolen jokes.

4. Once you can get a reaction with tested material, branch out to variations and introduce your own material. (Don't stick with joke theft forever, just use it as a transition, so you can isolate other things to work on.)

* (2) probably requires multiple distinct social groups. Even in the same group, you can get away with this with a little hat tip, like, "It's like that time when John said X..." Or if you build from that into storytelling--everyone likes hearing stories about times they said or did interesting things--so you'll have a sympathetic audience while you practice some timing and rhythm.

The biggest problem with such a tax is that all countries would have to implement it. When the US is accounting for about 15% of global carbon emissions we can’t solve the problem just by reducing our own carbon emission.
The person who posted this on HN is the original author of the paper, please be somewhat respectful and not rude. If you want to call him out, talk to him directly here.
It is. Elrich's population bomb was an earlier example that has been wrong so far. I recently re-read Whitley Strieber's Nature's End, published in 87. Although a fictional account of the future similar to the Blade Runner movies (in terms of environmental impact), it embodied the idea at the time that the Earth couldn't support several billion humans. Set in the mid 2020s, the northern forests were dead from acid rain, the Midwest was a desert and the Amazon had mostly burned down. 7 billion humans had completely decimated the biosphere.

So I'm a little skeptical whenever the latest doomsday predictions roll around.
I would agree, going the other way.

Before university, all I knew of rich folks was that they poached the good teachers from my high school (we were a magnet school in the poorer inner city, back when cities were poor). Lets just say that I found that there was more nuance to all those kids from suburbia.

I went into university steadfastly believing the roster sheet of progressive policies. Then there was economics class, and the in-depth conversations around that, and I came to realize that a lot of policies are double-edged swords, either difficult to implement correctly, or just outright too good to be true. For example, you can't really elide the fact that prices provide important signaling to the markets, that in turn influence supply and demand.

That having been said, I don't think the libertarian wing nuts I'd met came to the same sort reckoning,... they still seemed to think the free markets are magic pills... so I figure that I learned more from the experience than they did.

University was a confusing time. There were a lot of folks who were a lot more privileged than me, who were smarter than me, but not very motivated. It would take many years after college before it became clear how things even out. (They are still on good footing thanks to their privilege, and they're not bad people. I have sometimes enjoyed seeing them again – when I do – like it was old days. I don't envy them anymore. And I wouldn't switch places either.)

Life is complicated. University forces a kind of mixing – and a certain kind of critical thinking – that forces you to look at how complicated it is. Sometimes, things just are.

I've been to the other end of the spectrum, been around lots of people who never went to school or who dropped out. Or who had it easy in university. I interact with folks who never had to pick up that kind of critical thinking. It eventually becomes plain and clear the kind of subtle difference it makes in people's lives over time, and across generations.

It is in life as it is in board games. Randomness and complexity obscure the "winning" strategies.
Oil will be a valuable feedstock for the forseeable future. Look at all the plastic in your house, in your clothes, in your car, wrapping your food, coating your circuit boards, the list goes on. Yeah, that's oil. Shame we can't harvest the plastic from the oceans and reformulate it into something useful.
When it isn't a bidding war. Before it began you selected your winner. You then conned the other players to participate, thinking they had a chance, just so you can get a better deal. All those others spent tax payer money to enjoy win, but had no chance.

Fixed after installing TK from activestate.
The US is indeed addicted to cars, and particularly for those living in the suburbs this is a sunk investment. It really doesn't help that the cities are (usually) NOT built to building codes that actually encourage privacy between units, that needs to get fixed too.

However, an upgrade path would be a great idea. That path must allow for the transit systems (either highly regulated utilities or community owned) to spread.

* New core has the target service level in place.
* That service links to a PROPER parking structure at en edge.
* Such structure should be SECURE (unfortunately monitored)
* Also package transport services in addition to people.

Renting 'a spot' in that area, as part of a residence OR as part of visiting should be low cost, and shouldn't /punish/ owning a car. The idea is you're incentivizing use of the new zone as well as commerce within it. The parking structures become a gateway as well as additional storage (and should convert to that when use for parking decreases).
According to the article, this change should make rail cars cheaper.
In addition, all the other cities spent tax payer money to out proposals together. That has no chance
Writing laws is the easy part. Actually enforcing the law is an entirely separate endeavor.
Interesting. I'm done with lazy 'intellectuals' who think they can offer questionable evidence and demand everyone accept it. Extraordinary claims require extraordinary evidence. What is the natural climate variability and what is the standard deviation thereof? What is the climate sensitivity and how accurately do we know this value? Why do the simulations predict warming that doesn't show up in observation? What happened to "more frequent, stronger hurricanes?" Here's an idea! If you have better answers for skeptics, which is your responsibility, maybe more people would agree with your claims.
agreed, that its not a single entity. UX is far more important to users than UI in my opinion. Google's UX used to be good but now I've experienced its shortcomings in many of its updated products.
Well, how about getting off the couch and voting next time if you don't like this stuff.
The short answer is that the Flutter team wanted a language that was something like Dart, and the Dart team needed a killer app and was willing to put a lot of effort into satisfying Flutter's requirements.

It's unlikely that Flutter could have gotten that level of cooperation and influence over a more successful language, back when they were getting started and nobody had heard of them yet.
But if 90% of the demand for oil (transportation) disappears and supply stays the same, the price is going to drop big time.
I hope you are right. I'd still rather live some place else in the solar system. This place is getting kind of crowded for my taste.
Understanding CNC Swiss Screw Machine and Its Functions
Functional programming was invented by Backus to solve the problem of interchangeable parts. Unfortunately, he did not finish his work, and as a result people are still trying to paper over the missing hole in the theory. State monads as described above make the process of storing and manipulating state a very obscure and mysterious process. This additional complexity and abstraction can only add to the lifecycle cost of software generated using this technique, with an attendant increase in maintenance cost. If you were to take a 10 year old, and give them basic training, would they be able to understand this? I doubt it, yet computers at their core are incredibly simple. So a better paradigm awaits.
You avoid paying more by buying products and services that emit less carbon and therefore are less taxed. This economic incentive is how the tax helps curb carbon emissions (and hopefully other forms of pollution also, why stop at carbon when the world is drowning in single-use plastic for example).
