Are there answers to the exercises? I'm kind of stuck on 3b in section 8. Should I evaluate from right to left - normalize 'y' lambda given a y-value of 5?

Then, in that case, there is only one argument (const 10) to pass to the 'fx' lambda and I guess you end up with a partial or something?

Or should the 'y' lambda and the constant 5 be considered the 2 parameters passed to the 'fx' lambda? In which case I guess the answer comes to be const 20?
How does this kind of writing still make it to publication?

The publisher doesn't have standards, they needed something to surround the ads. The author might have been more serious about the topic than trying to fill space to sell ads, but lacked the tools to bring that insight. The editor in chief should keep them on the bench learning, covering topics they can speak meaningfully on, or should have hired them in the first place. I doubt this publication has an editor in chief (though there is a distinct possibility that someone ineffectual might hold that title).
Metafilter had a great system. If you want to register an account, you pay $5 toward site maintenance. Presumably this would heavily discourage bots while still allowing folks to maintain alt accounts.
so instead of editing user posts, they're going to change the scoring to prevent the political sub they don't like from filling the front page.
sorry man, it's just not that useful in it's current form. Ranking reviews by usefulness might help, but it's a babystep. I think what I would find more useful is being able to compare camera's and lenses side by side, although there are certainly sites that already do that. I think people care about 1) budget 2) lens ecosystem considerations 3) the "gotchas" (hard to quantify, but you see stuff like "this camera requires you to hunt through 7 menus just to change this one setting", or this would be a great camera except _____), which your site does very little to address.
Too much signup friction, that would go against the status quo of growth = revenue.

Grand paring down? Since when? The typical US home has pretty consistently grown in size year over year for at least the last 4 decades, gaining about 250 sqft every decade.

Wow, I didn't know they ever shipped those things.

No thanks, my stack is big enough, but I betcha someone collects those!
Tying a user to a phone number does nothing but invade the privacy of most users, and slightly increase the costs for those who value their privacy.

Not "instinctive", but "sensible". Saying "excuse me" or "passing through" would work just as well.
I don't get why he's installing an operating system within an operating system. (I use Emacs).
Yeah... the article itself is about the perils of meat privilege, yet the editorial staff can't even escape their own biases.
You could, but it's very unobvious. Unless you had it as a clear convention across the code base I'd imagine it would just lead to a lot of confusion.
I used to work for a business that Google wants to buy. That is one way to get pipelines opened up to internal Google teams.
I guess you could do something like vocaloid does to better "shape" the sounds of each word. I guess its pretty tough to do that automatically though, since words by themselves don't convey the emotions that they should be portrayed with.

I mean, a word or phrase could very much change meaning depending on how its spoken (excitement, disgust, fear, sarcasm etc) and even if the context is available in the text (as is often the case), its rather difficult to machine-detect, at least, for now.
Apple has also been using bsdiff for incremental app updates (on device). I discovered bsdiff while poking around in one of their update files.
You might be correct they don't care too much that monsters look alike. Many, many years ago on the Mac we had this Bomberman clone called BOOM and it was a mix of Bomberman gameplay with graphics that mimic some Doom monsters [0].

It's less that naan is "new" to Indian cuisine and more that it isn't indigenous.
Actually, I think alpha-go would be more in the "looked cool" category. It was an applied engineering task, not so much a fundamental approach change like adversarial networks. That's not to take away from the monumental nature of the feat, but it seems like this blog post was more about higher level developments. Similarly, pixelcnn and wavenet were "what can you do when computing power is no object".

I would have liked to see something on RL^2 / "learning to reinforcement learn" which do seem like huge developments to me, but maybe are too new to see the impact of yet.

I hope this "trickles down" to medical applications fairly soon. I have awful night vision, and a pair of normal looking night vision glasses would be just the thing.
Is it just me or do these pitch pages always seem very light on what the software actually does... does it aggregate logs? LD tweaking maybe? Is it a kernel module? What is this technology?
Reading the article it hints at the reality that it doesn't actually work like passive glasses as it implies. the blueshift effect happens because they're using a laser to excite the crystal and it later emits the shifted light, but you have to pump a lot of energy in for that output. Simple conservation of energy implies this won't work for normal night vision applications, instead they want to shine a laser spotlight and use the reflected infrared laser light for vision. cool material science for sure, but not a replacement for nightvision goggles which don't broadcast your position with a bight spotlight.
An interesting perspective, but false. Risk of legal action should definitely inform your conduct, unless you want to go broke. You can easily spend all your money paying lawyers to defend you right up until the point you are declared "not guilty" (or in a civil case, until you win). That doesn't make it a good idea.

So yes, you should always try to do the ethical thing. But your moral calculation should at least consider the risk of being sued and take that properly into account.
Didn't he have something like 17% support? That's hardly minor.
Vocaloid still sounds robotic (at least, to me). It just so happens when you make autotune/melodyne'd pop songs, it really doesn't matter.

"The best course of action that Alphabet has is to acquire a proven aerospace company"

It's a good long-term bet if it's a defense contractor that's been getting contracts for decades. Could hedge a bit against what the market might hit them with. Plus, they're trying to get tighter with government anyway. They'd likely acquire people good at doing that, too. Then start brining their tech or services in defense industry in general more than now.
You're also pretty much asking to get audited if you claim a home office deduction, so make sure you have your ducks in a row if you are going to claim it.
Love interpolation, still shaking my head @ the typing syntax

> So, this is more of a success story than most of us might consider savory to think about.

In general this sort of thing is probably far more common than you'd think (top brass gets paid, everyone else gets a "thank you"). If I'm not mistaken, that's what happened at Sam Altman's company, and a good number of the YC company exits.
Makes sense. I guess what I was getting at is that introducing Decimal to the example about f-string interpolation makes the example more complicated than it absolutely needs to be, but I can see why they did it.
They might be useful if you already know what they're supposed to look like, but if you've never seen them before they look like ink smudges.

For me, it's a major detractor from something that could have been a great resource. I would love to know more about the breads of the world.
Yeah, gan's are huge. Mimicry plays a huge part in human learning; especially in language learning, where native fluency is more or less defined as 'difficult to distinguish from the real thing'. I expect we'll see a lot more coming from adversarial models in the future.

Almost none, well the only thing that is annoying is that type inference currently won't work within lambdas but otherwise it's great.

We use Lombok on all our Java services and have never had an issue (we do about 33million requests a day across these services so they are real battle tested and used code bases).

Type inference, automatic builders, removal of getters and setters (@Data will automatically add getters and setters to the fields of a class) and (@Value will make the immutable version).

I would never work in Java these days without being able to use Java 8/Lombok/Javaslang/Guava.

...AMES? I don't know how active it is as an aerospace hub, but it DOES have all that.
> "this time it's different"

It may be different for other reasons but the main difference I note today is the number of opensource AI/ML platforms that are trivial to install, use, play, experiment at pretty much near the peak computing capacity of the hardware we use today. Exploring the vast search space of reality has never been easier and faster than today.
I have been waiting for object rest and spread for ages. Thank you to the maintainers for working hard on this feature.
I'm not sure how to react to this news. I have 3 pebble watches and 2 of them are broken. If fitbit can fix the pebble quality problem then I may buy more.
I enjoy how the article sometimes seems to have the point of view that this is the first time engineers ever had to work this way. I don't think they are taking software engineers and asking them to create drones. These seem like a lot of the same problems Boeing would have making drones or that UPS would have trying to make deliveries if such drones already existed. Nothing unique to Silicon Valley companies in this respect

I have struggled mightily with gmail on my phone (especially when trying to negotiate threads).
Perhaps it's the fact that I'm inexorably falling deeper into academia every year, but government research is definitely NOT a waste from my perspective.

Some of the best PhD students, working on some of the most interesting projects in my experience all had DOE or EPA grant projects. I think this sort of research deserves a lot more money since, in my (biased) opinion, it pushes humanity forward through public access of research in the form of publications, theses, and the strict requirements that data be preserved for future reference.
Good idea. Get on it.
Agreed. I used to use the app religiously, I'm now using News Republic more often. I don't watch on the TV at all anymore, it makes me feel foul. I remember watching a BBC journalist throw bottles of water for a group of desperate people, who reacted by sidestepping the bottles and continuing to watch the idiot in front of the camera, completely disinterested in the water. Of course, he only started "assisting" the desperate after he'd finished his drawn out description of how desperate they were. They're increasingly tabloidy in order to maintain market share, but it's just increasingly repulsive.

There are lots of ways around that. His stock is worthless, sure, but he probably has something else, whether it's a huge retention bonus (cash or Fitbit stock, which is public and can be sold), an executive-level salary at Fitbit, or some combination of the two. There's also the possibility that he sold some of his equity to investors for cash earlier on.

EDIT: I was wrong, he is joining YC. Thank you for pointing that out kobeya.
The former, if all things remain the same in terms of computing power and availability of data. I think betting against improvement in either of those areas is a bad bet so I'm optimistic we'll continue to see really interesting things in the near future
The only distribution I've really enjoyed using for development is Antergos (Arch derivative) because all my packages are up to date.

The only way another distribution would catch my eye is if it targeted a specific hardware platform. Like, if a group of developers built a Linux distribution around Dell's XPS laptop line so that hardware support was perfect.
λ calculus is left associative - that is, a sequence of applications A B C is interpreted as (A B) C, so we first reduce (λf x. f (f x)) (λy.* 2 y), yielding λx . (λy. * 2 y) ((λy.2 * y) x), and only then apply 5 to it, which finally lets us unravel everything and get 20.
You definitely need a window to qualify as a bedroom. It has to meet certain requirements that basically boil down to "could a 10-year-old escape a fire through this window?" Although "not falling to death after climbing out" isn't a requirement.

I believe technically a bedroom in the US is also supposed to have a built-in closet of some sort and a door that closes the space off. Lack of either of these often means a room is marketed as an office.
In our team nobody speaks English as first language. Now we have to hire actors for English voice narration in our demo videos. If Amazon Polly gets better, we might be able to switch to synthesized voice narration and don't deal with actors anymore.

PS.That would be one more job lost to AI.
World eSport: ultimate social network for eSport and Gaming
Async/await support for most browsers and node-0.12+ is definitely a welcome feature, callback hell and tripping over promise chains is definitely one of the most painful experience in TS development IMO.
I understand that people not being able to look you in the eye makes you feel extremely disrespected.

But I don't think it helps anyone for you to jump from there to assuming that what's going on inside their head is "[I don't] respect [this person] as a human being".

To be clear, I think other things you mention, like not getting out of your way, are evidence of that. But eye contact? Probably anxiety from an unfamiliar social situation.

Seriously? Compare Polly's English samples (particularly #2) in the original article with the Google's WaveNet samples:

WaveNet 1: https://storage.googleapis.com/deepmind-media/pixie/us-engli...

WaveNet 2: https://storage.googleapis.com/deepmind-media/pixie/us-engli...

There just isn't a comparison -- Polly sounds way more robotic.
no. name picking is a rabbit hole, proving your product/service is far more important. pick something unique so that people can google it and come up with a meaningful result. If it becomes a problem, you can always change it AFTER you've proven your idea.
Chatbots and the Productization of Conversation
They don't even require an e-mail address. A great thing about reddit if you ask me.
They didn't "just make" anything. They've had vote fuzzing, shadow banning and more from early days.

As both the techcrunch post and the actual reddit post say, the rules around it were complicated and hard to reason about. They've basically refactored and come up with a simpler set of rules.
Hi Kristopolous,

In a nutshell, Monitor in a box is a system/application monitoring solution based on Ansible, Icinga 2 and Grafana.

I would like to kindly point you to our demo to see what our software does.

We've also made our code available at github, and I invite you to check out our README to get an idea of how to begin using.

I hope that helps clarify what we're trying to do.

If the drone is a lower-cost delivery mechanism, then it has the greatest impact on low-margin items. Tablets can afford FedEx. Lettuce can't.
To me, most of the JVM languages have 2 similar problems with the "defaults": references are optional, rather than mandatory; objects are mutable, rather than immutable.

It's past time for a language that makes it's references mandatory unless you explicitly indicate "optional" / "maybe" or whatever. Slapping "Optional<...>" on stuff when "mandatory" isn't enforced seems to just make things worse.

Similarly, classes/objects, methods, modules, packages should be side-effect free, unless there is a flag for mutation or other side effects.

We don't need Java 1.9, we need 2.0, with "breaking" (fixing) changes :-)

Scala shows some good ideas, but it doesn't go far enough. That, and I kind of liked Groovy, too, as I would like to be able to turn on and off strong/static type checking. (default on, but if you ask nicely...)
Have you looked at Truffle & Graal, which are going to be introduced in Java 9 to some extent?

In Haskell: `2.3 :: Fractional t => t`

In other words, it can be inferred to be any type that implements the Fractional typeclass, which includes Decimal types. Not that it is relevant here, because you basically need to have types for something like this to work, if you have proper type inference, then you don't need to assume any type, and can just interpret a literal as whatever is needed.
Is it? That's true of taxis, but the scale is pretty different for package deliveries, where you have a single driver conveying a LOT of different packages at once.
Well, if they are a C# shop, that might be a really easy way to get their app on phones while being able to reuse code that might already exist, while also not having to deal with phone specific toolkits.

I feel like I'm starting to sound like a fanboy - but it's because I've had other smart watches and it's just so much better. Why not consider garmin? Not sure if their SDK is going to hit the mark as I'm guessing you want complete control and it's definitely not that, but they have everything else you've asked for.

Same here. I already used it exessively in JavaScript to prevent mutations and missed it a bit in TypeScript.
Could you expand? This looks similar to how it is done in Rust.
While I'm a data point against the article (my home office: 27" 4K, Das Keyboard, Aeron, and other comforts) I think we're starting to see a generation of workers who have used laptops their entire life.

Hasn't Google had a Text-to-Speech service (for e.g. the speaker button in the Google Translate page) that's been around for aeons?

I remember it sounding pretty life-like. Don't know if they expose an API for it, and sell it though. (It would be great if they did.)
I like how they announce it after Black Friday and Thanksgiving sales. I'm sure they knew of it during the acquisition as it would be all laid out, but they wanted to squeeze in more sales. Hopefully the average consumer gets wind of this and return their product.
bad argument. we dont let bakers discrimate against gay people. being a private business, doesnt mean you can do whatever you want.

Edit: I agree with the posters below me. My point is a private business doesnt mean I can do whatever I want. There are still social rules and laws that need to be considered.
We are going OT here, but one last comment in this thread to clarify what I meant.

Putting a comment saying just "Just another vile article", without any thoughts about why it is vile, is just completely against the guidelines (from the points mentioned in my previous comment). Even if you agree with its content or not.

Also, I do not believe the guidelines encourage people to down-vote for disagreeing (or at-least from my understanding). It is just in our nature and the consequence of the fact, that there is a down-vote button. (I have never tried it, still under 500 karma.. :) )
"What's possible, though, is accumulating Python objects in memory and keeping strong references to them12. For instance, this happens when we build a cache (for example, a dict) that we never clear. The cache will hold references to every single item and the GC will never be able to destroy them, that is, unless the cache goes out of scope."

Back when I worked with a Java memory profiling tool (JProbe!) we called these "lingerers". Not leaks, but the behaviour was similar.
Hurrah for object spreads! Time to go grepping for calls to _.default and _.extend.
Why does FitBit have the responsibility of providing support for another company’s products? If they didn’t buy Pebble, it would’ve shuttered anyways and they might not even refund the preorders.
Doesn't that aid my point? Why did they choose to try to prove same day delivery with items which cannot sustain the cost of deliveries (yet) given current technology. Why not prove the concept with higher value items and then move down the chain --as FedEx did. This approach seems a bit backwards to me.
These days it seems like an illusion with respect to government oversight, and having a username is a simple way to anonymize yourself against your peers.

I'm all for it since it seems like it would reduce trolling.
