Some devices will use more energy to get a room to X Celsius.

Those devices are less energy efficient than the other devices.

Well, Germany announced that it accepted a patient with Ebola.[1] I guess it's not completely out of the question now?

I'd welcome a chat / email. I've spent most of my career in educational software, thought frequently of how to improve it, and would be happy to talk with someone of a similar mindset. Added an email to my profile here.

I do like the baby sim idea. I know some language learning systems go with a very gradual immersion in a similar way, and work in children's books and television as part of it, but I don't know how effective it was. Sounds like it should work well.
I made really bad experience with iAD and other monetizing frameworks. 0,50$/day and >2k impressions. I think iAD works only with iOS games. Can you share a link?
I don't see why they wouldn't, they already sell their powertrains to other companies.

It would probably depend on how much extra capacity they have. The Tesla vehicles are in high demand and only going to be in more demand when they start rolling out the Tesla 3 (which is really the 4th Tesla isn't it, I guess they're referring to it being the 3rd generation with the Model S and X being the same generation).

That's what I assumed but did a quick Google Maps search and it appears to be mostly a grid at first glance, unclear wording, "The UK's roads are quite a different test bed to many West coast US cities where there is no grid pattern, roads are smaller, and curvey."
When I started this about 8 years ago or so, i used [this book](http://www.headfirstlabs.com/books/hfhtml/). It's structured as a case study, a coffee shop owner who wants to make a small webpage.

It's amazing how it's well written and fun to read. I like it puts some effort in showing you quickly the benefit of what you learned, you never get the impression something is pointless.
(NB: it's big but you don't have to read it all. I read say the first half, than used it more like a reference book.)
They are only very efficient in warm temperatures. The colder it gets the harder the dehumidifier has to work and the less efficient it gets - as it operates based on a temperature differential. So I suppose, if you are running a dehumidifier in a cold room, you need to particularly consider how well it operates in cold, some dehumidifiers are particularly bad in that environment.
This is a bit off topic but does someone know how this book is generated, which tools are used?
It was a nice talk, except for this:

If you think Instagram is just a collection of photo filters, you're missing the big picture. Maybe photo sharing won't lead directly to world peace, but helping people to see the world through the eyes of others looks like a step in the right direction to me. And they grew to over 200 million users in less than four years.

The whole talk was "building the impossible", and I think that's what Silicon Valley used to be about -- about going from 0 to 1 (in Peter Thiel's term) and letting the world go from 1 to n. That's impossible and that's what the valley did for decades.

But now the measurement is, "How many users to do you have today?" It's superficial and meaningless. Instagram is a great success for its investors (and I have nothing against that) but it won't be around in ten years, and more importantly, nothing it brought forth will be around either. Instead of 0 to 1, it's more like 1000 to 1001.

I have no problem with people making money, but you make what you measure, you make what you fund. And we're getting what we make: Flappy Birds and fucking Instagram.
That's not what I mean. Researchers in all countries get infected with these things all the time, too. But it's questionable whether Ebola specifically can take hold in the northern countries at all.

Haha, sorry, I meant in Sublevel, not in your comment. I replied on yours because I felt it was related.
> But if things have got better, then perhaps the criticism is no longer valid?

Part of that is due to the share amount of code out there doing things bad ways that were almost encouraged years ago, and tutorials still out there teaching people to do things the old less good ways.

Of course a lot of it is people who haven't touched the language for many years (such as myself) who are at this point a lot less informed than they think they are!

Another issue is that the new frameworks seem to get the positive news, not the core. The language use to describe PHP related libs/frameworks is different in my experience which makes a perception difference: PHP frameworks are often referred to as "making PHP behave" or "removing the cruft from your workflow" where frameworks for other platforms would be described as "helping you make the most of <platform>" and "increasing your efficiency".
Why would you need ubiquitous automobiles in a human scale city, though?
That is reassuring. But do you have any references for that? The only study I can think of is the one where it was showed that Ashkenazi Jews had higher intellectual aptitudes than other ethnic groups. Which would prove that intelligence is on a scale and not on/off. Of course, the result is highly contentious and was criticized on various grounds. One of them being that it is very hard to discover whether a trait is due to genes or the environment.

Parameter order is an important part of a function's interface. In particular, commonly-used arguments should occur before call-site-specific arguments, so that we can specialise the function. array_map gets this right:

$asBools = partial_apply('array_map', 'boolval');

$asBools(['hello', '', 'world']) === [true, false, true]
$asBools([-2, -1, 0, 1, 2]) === [true, true, false, true, true]

array_filter and array_reduce get this wrong, requiring awkward argument-shuffling:

$inverseFilter = partial_apply(flip('filter'), 'boolNot');

$inverseFilter([-2, -1, 0, 1, 2]) === [2 => 0]
array_keys($inverseFilter(['foo' => true, 'bar' => false])) === ['bar']

$allTrue = partial_apply(flip(partial_apply(flip('array_reduce'), 'boolAnd')), true);

$allTrue(['hello', 'world']) === true
$allTrue([true, true, 0, true]) === false

Note that a) if specialisation was easy, there would be no need for default arguments and b) having default arguments at the end is exactly the wrong way around for making specialisation not suck.

We could sweep this under the rug by saying it's awkward because it's not idiomatic PHP; but one reason why it's not idiomatic is that it's awkward!

Just look at Javascript, where functions are slightly less awkward; there are lots of functional APIs in wide use, eg. Underscore.
I'd argue that if you're only 10 minutes away from work by car, then you're not really living the "big wasteful" suburban life. Real sprawl (I'm unfortunately quite familiar with the kind outside of Toronto) involves long drives and frequent wrestling with slow traffic to get anywhere, especially during rush hour. Suburban houses are cheaper precisely because they're far from places people want to be.

That said, with Skype, remote work, Netflix, and Amazon Prime, I guess who really needs to go anywhere these days anyhow?

There are gel filled alternatives that can be heated in the microwave. No idea if they retain their heat as long.
Heating can be more than 100% efficient. Before you go "what, lol, no" - let me clarify. Obviously it can't be even 100% thermodynamically efficient, but a heat pump for example can generate 3-4 kW of heat from 1 kW of power. The rest of the energy comes from the environment obviously, but naively assuming that the 100% efficient power-into-heat is the best you can do is not true.

Well, rust does have pure functions (as most programming languages) you just can't tag a function as such to have the compiler enforce the purity for you (it used to, though).

That being said I'm not sure why the author mentioned that point in particular. Maybe he feels that having immutable-by-default semantics encourages writing pure functions?

The advice in this thread to "wait to form a company" is just flat out wrong. Form an LLC immediately. Use it to open a bank account, and use that to open a credit card. Use those accounts for every single thing you spend money on relating to this business.

Even if the project goes nowhere, you can use this account for other side projects you want to make money.

Accepting any money from anybody to your personal account is just stupid, and will make for a huge nightmare when you want to transition to being a huge business or paying taxes.
Thank you! Perfect response. I'm a systems programmer, mostly working in VHDL, C and assembly. I use and write API's all the time. I've never used an "API" over HTTP before.

I think the confusion comes from a slow divergence of terminology. Web providers offered "API's" to allow people to access their services, these were kind of API's in the sense that an application could use them. However, it seems that for the web development community has begun to think that an API and an HTTP based API are synonymous (they are not!). Hence my confusion here.
No, Samsung is not going anywhere anytime soon. There are other local players like Micromax, Spice and Karbonn.

The difference with humans is that we can modify our environment, which means we can and do modify the fashions of greatness. Hence the many opinions telling us what is cool today.

To exercise free will one must decide which "choices" are deterministic (i.e. not actually choices) and which are open to imaginative innovation. It is the definition of greatness which is personal, not its achievement.

If you have a guaranteed job, can you be fired from it? If so are you cut off from all income for some period of time? If not, what stops somebody from turning up and having very low or no productivity and demotivating others?
The writer doesn't justify his insistence that a Job Guarantee "IS NOT ‘MAKE-WORK’". It seems to me that if the primary purpose of a job is to provide work, then it is by definition make-work.
The fact a user might have installed from somewhere other than the webstore, or if they're on Safari or IE, is entirely irrelevant - the 326k is active users, eg people who have accessed the Rapportive API in the last week. That's everyone using Rapportive regardless of where they installed from or which browser they're in.

Whether or not Rapportive is limited by GMail is a good question. Getting 0.065% market penetration after 4 years would worry me, but doesn't mean they weren't making giant piles of cash. You could easily run a profitable business with 326k users even if only a tiny proportion are paying something. The important thing to take away from Rapportive's numbers is that a huge market doesn't automatically translate in to a huge market of available customers for your product. There might only be a tiny proportion who want what you're offering. Fortunately that doesn't actually matter if you can run your business profitably anyway.
Yep, and all the hypocrisy...

PHP, Node.js, Go and OpenResty have a versatile ecosystem with both libraries and optional (micro) frameworks.

I prefer the newer trend of micro frameworks and for simple websites just raw PHP 5.3+.

Let's say you want to create a set by recursing along a million long sequence, collecting the unique values. This would be done with an operation called `reduce`.

The time and storage complexity of that would be exponential if each step you had to clone a copy of the output list. With a persistent data structure, as much of the structure as possible is re-used.

And a list is the simplest possible structure. What about a tree?

Using `reduce` is, I would say, in the top 5 techniques used in functional programming. And it would be severely hobbled without efficient persistent immutable structures.
Beware here! There are a couple of different products you can sensibly form on data. So you have to make it very explicit which you mean when you talk about them. You can't generally interchange them in all contexts, but in some contexts you definitely can.

In Type theory, the product is a product in the sense of category theory, which is a very abstract notion of product indeed. The idea is that given objects, here types, A and B; you can form their product, A * B and that is also a valid object in the category. The diagram then universally identifies the A * B element as the one where you can project out of it via the 1st and 2nd projection such the at given diagram commutes, etc. And it is important to stress there are many products for which this property hold.

That's not true of all houses and especially not true of cheap apartments, whose residents would benefit the most from saving on heating.
We've been in our current flat in Edinburgh for 9 years - we've never heard a single sound from neighbours and I know there have been families with young kids and teens living directly next to us.

It's not a really old property - ~200 year old townhouse converted to flats about 120 years ago.

Walls are roughly 1m thick sandstone.
My German apartment has drafty, unsealed wooden window frames, and the window in the kitchen is a single large sheet of glass. We have to hang a rug over that window in the winter, as it feels like you've left a freezer door open if you get within 3 feet of it.

But the walls are indeed very thick!

There's another historical difference between Scotland and the US here: the US has a near-unlimited supply of wood, while Scotland was mostly bare of trees by the 18th century.

Much cheaper to build walls from local stone and save the imported wood for the floors and roofs.
S/he says that government jobs would be those that benefit the community. It's not hard to come up with examples of those kinds of jobs - care for the elderly, cheap & healthy kitchens (like kitchens for the homeless, but for everyone instead), more repair and maintenance of infrastructure or new infrastructure (e.g. before WW2, German's increased employment by building highways throughout the country), culture and art events, recycling, running non-for-profit stores (for many basic items, the margin of the store is much greater than production costs) ...

IMO, that's much less make-work than advertising, sales and similar (basically, jobs that exist because your product is not good enough to sell itself).
