Should we write optimization models in modeling languages?
My biggest challenge with (learning) Scala and the Scala community is that it feels like nobody is actually shipping software, or advocating for making shipping software easier.

And that's a shame, because Scala is language I love for writing a few dozen lines of code, and expressing a domain concept. It's a fantastic language for solving a homework problem set (and it's origins may be part of the reason why). But every library feels like it was concocted as a search for purity with zero attention given to the user experience.

The community is badly missing a DHH or Kenneth Reitz -- someone saying: "Ok, it's cool that we have this academic purity stuff and all that, now let's get serious about shipping software, and making tools that help people ship software." It's not that this view needs to dominate a community, but right now it's thoroughly unrepresented in Scala land.
I think "the thing you are building is too trivial", as a criticism, implicitly expands to "you should be building something more important than the thing you're building". And it's correct to be skeptical of any "you should x" claim from someone who is not xing.
Conciseness is optional. Sometimes a new Scala programmer will learn functional combinators and try to cram a lot of logic into one line. Breaking things up into semantically related steps and assigning each step to a val with a descriptive name will make the code more readable to others (and the author's future self)

The story drives the single player experience, ending with a fight with the main antagonist GLaDOS. This is then expanded on in the second game. The story contains well known characters such as GlaDOS, Atlas and P-Body. Particularly GLaDOS's deadpan humour is a big part of the story and is referenced frequently.

I have to take issue here. I don't need to be a "builder" to see that what a given startup is building is either worthless or an attempt at solving a non-problem.

I'm not a helicopter pilot, but if I see a helicopter stuck in a tree, I don't need to be one to know that the guy screwed up.
The notion is actually that criticizing something you don't understand is valid but not necessarily useful.
Fair enough. But I don't think "Hard Tech" is being used as SV jargon here. The first paragraph defines what is meant by "hard technology" mainly in the negative -- critics who say "SV isn't doing hard technology", for whatever value of "hard technology" they mean.

> Money is by definition a purely financial asset, a liability on somebody's balance sheet.

Maybe Econ 101 has changed, but I remember learning that "money" was:

- A medium of exchange

- A store of value

- A unit of account

When we were on the gold standard these were all true. Now that we're off the gold standard gold is no longer a medium of exchange or a unit of account, but one could argue pretty effectively that it's a better store of value than dollars have been, and it's done so for throughout history. (I'm talking time periods of decades, not the post 2008 crisis volatility here.)

The fact that the system we're using now is debt-based rather than based on precious metals should't change the definition of money, however.

OpenGL is partly these widely available graphics algorithms. Thank you for explaining them so well here. OpenGL also has a particular architecture that provides concurrency and extensibility among other things. If we are talking about OpenGL specifically vs other Rendering Engines, then it would be good to explain the architecture to help folks understand the reasons why OpenGL is so widely used.
I believe that this (for want of a better phrase) perfect economist picture of parents is so swamped by culture and superstition and politics and all the rest of it that it's effectively invalid.

Many parents do want their children to be happy and healthy, but I believe the number who do this because they assess what their stake in "Project Children" is and conclude that their expectation value is higher with happy healthy children is vanishingly small.

They could have used tables and comic sans, and it would have been an improvement because if nothing else I could have read the content.

As it is, I kind of get the idea...sort of. Something about satellites, imagery, real-time somethingerother. There's complaining about weird scrolling and "broke my back button", which many of us tire of, and then's there's "hi! Didn't know if you noticed, but your site's broken on the most commonly-used browsers, broken to the point that many cannot read what I'm sure is absolutely awesome content." In other words, had this been a marketing page for something people don't give two shites about, the column that holds the abandonment rate in their analytics DB would have to use a float lest the tiny, tiny percentage of people who didn't immediately close the browser tab be recorded as "zero".

So I'll take your word for it when you say it's awesome. Currently, I am not equipped to confirm that with Mac OS X and Safari or Chrome.

>Booking anything 1-bedroom and larger somehow seems to signal to the hotel industry that you've finally made it to the Forbes list and therefore no expense will be spared.

It depends. Absolutely for a typical downtown hotel, their relative handful of suites tend to be oriented toward being used as business meeting rooms or by people who are really price insensitive. You can sometimes get deals on weekends and the like but, yeah, it's a bit like business and first-class pricing on planes.

It's far less true of the residence style hotels though (e.g. Marriott's Residence Inn). In suburban/sprawl locations I often favor these because it's nice to stretch out on a sofa. Some locales, such as Vegas, also have suites as a pretty standard offering.
The children are incapable. The parents are not.

The quarter rig (imagine cutting a 90 degree cross section out of the reactor and plonking it into a rig hall) we made was for a remote solution we did for EDF for some of the nuclear fleet in the UK. As much as it would have been fun to make a full size to scale rig, it would have cost a small dortune and we are a business afterall and profit is our end goal. So we only made enough of it to be able to train the operators to deploy the kit on site.

In terms of Fukushima, the manipulator we are developing will eventually have a testing rig built for it, however we have only just been involved on the project in the last month and as such haven't reached a stage where we need to build the rig yet. With the Japanese government funding though I imagine it will be a similar job with a scale rig.

In the same vein what would happen if Apple decided to destroy their master key and all backups?

These Are the Data Centers Where Cybercriminals Hide
The community is the worst part IMO, and it all boils down to the Typesafe vs Typelevel communities. The typelevel crowd want to turn Scala into Haskell whereas the typesafe crowd have always recognized it as an ML dialect first and foremost.

The rift pollutes and bloats your dependencies, and causes problems with unexpected behavior and unreadable documentation. Trying to shoehorn libraries into my projects that pollute their code with these new standard libraries with lazy functionality and its accompanying monadic bullshit[1] is a huge thorn in my side. I wish the typelevel crowd would just accept the fact that Scala is an ML language, and adopt Frege instead if they can't handle that.

You make a sensible point against this particular bill.

I just can't understand why any resemblance of a limitation of the privacy over electronic communication is greeted with such outrage. I do understand that encryption can be either controllable XOR secure. But my point is that secure encryption has never been a right: actually, the discussion has just started, due to the recent spread of its usage.

Again, telephone and (thanks for reminding) courier have always been controllable, thus not secure. Deciding whether a non-controllable medium of remote communication should exist, and who may use it, is a social and political question (like, for example, cloning: it is technically possible, but drastically controlled by laws). I understand it's quite natural for us HN-ers to stand on one side, but the world is bigger that HN.

With more than 2,000 people in its Slack channel alone, I think Kotlin is a bit more than marketing hype (to compare, Java has about 500 and Scala 450).

I'd say both Kotlin and Scala are about equally good when it comes to interoperating with Java.

There’s nothing inherently wrong with a touchscreen, IoT light switch. But the main problem here, apart from using an insecure legacy protocol, is the use of a general-purpose OS like Android instead of an embedded OS.

It’s not just this light switch – Android refrigerators, Android ovens, Android washing machines are all using a wildly inappropriate operating system for single-purpose devices. The problem is likely that it’s a lot easier to develop for Android than it is for a proper embedded OS: It’s faster, the commodity hardware is easy to procure, licensing fees are minimal to none, and it’s easier to hire developers.

The first company to bring to market a more IoT-appropriate, yet accessible combination of operating system and SoC reference designs stands to become a massive player when IoT goes mass-market.

Ah, a favorite is a function that
is differentiable but its derivative
is not Riemann integrable!

Recall, a function is Riemann
integrable if and only if it
is continuous everywhere except
on a set of measure 0. So, the
derivative has to be discontinuous
on a set of positive measure.
Now, to construct one of those!

Here's another favorite: For positive
integer n and the set R of real numbers,
suppose C is a closed subset of R^n with
the usual topology. Then there exists
a function f: R^n --> R that is
0 on C, strictly positive otherwise,
and infinitely differentiable.
So, for C, take, say,
a sample path of Brownian motion,
the Mandelbrot set,
a Cantor set of positive measure,
etc. Can use that function to
settle an old question in
constraint qualifications for the
Kuhn-Tucker conditions in
optimization.

Or, any closed set can be the level
set of an infinitely differentiable
function.

Sure, really fun reading for such
things is:

One is that we would have a single point of failure.

Another issue is that we can't count on it being expandable space-wise going forward past the single machine level, meaning we can't just assume "and we'll add more machines if data builds up."
