The majority of those suppliers provide boron-impregnated plastic, which is fine for e.g. shielding spallation neutrons from a medical linac head. Reactor shielding is orders of magnitude higher, so material damage is a real concern. Not to say that people can't or don't use that material, but it is not the most cost effective stuff.

Frankly, the best neutron shielding in the world, on a per-cost basis, is water with borax. I don't know why people don't use this more. We used to use stacked bags of borax as neutron shielding when I built a fusion reactor (non-self sustaining, of course), and we had more than enough shielding to handle 2.45 MeV neutrons for under $1000.
Perhaps that Google's Nexus release itself was timed to steal Apple's thunder (the date of which has also been known well in advance)? I'm sure something like this is the case, though we can, of course, speculate all day long about who is trying to steal whose thunder.

The real explanation probably is simply that both have devices that they want to release in time for the holiday shopping season, and it does not do either of them any good to have a new, competing product on the market, dominating the media coverage. If their competitor's product is out there being talked about, they want to make sure their own product is mentioned in the same breath. Who is stealing whose "thunder" is just a subjective spin that we put on the events as observers.
This reminds me of what a very wise person (a business owner I used to work for) once told me. In an answer to the question "Isn't the customer always right?", he told me "No, not always. And when they are wrong, it is our job to convince them otherwise. If successful you will have a customer for life."

Really? $158k, minus kickstarter's cut, minus a bunch for the physical backer rewards, minus the production costs for the videos, probably minus some more for taxes, seems like that good a deal for a project that's been occupying years of her time already and basically forever ruined her ability to do things online without getting swarmed by abusive trolls?

I think you're understating the effects of continuous harassment and repeated death threats and so on against her, and overstating the certainty with which anyone can say there's no physical danger.
I don't have any studies or stats to back me up, am just going by personal experience here.

I'd rather spend a few dollars more for a higher-res screen than for a few hours of battery. The impact on my quality of life (less eyestrain, less migraines) has been really noticeable since I managed to get "retina-like" resolutions on all my devices, and since then I've been a true believer in the benefits of the race for pixel density. I just wish they'd blast a little less light at me (e-ink is still in another league), but I guess one can't have it all (yet).

Regarding size, keep in mind the changes in Android will make it easier to use the phone with one hand despite the larger size.

The floating action button in material design places important, frequently used action within thumb's distance.

Android's use of the back button is also beneficial for larger screens, since back is an extremely common action and keeping at the bottom of the screen reduces reach distance.

There will definitely be cases when it will be inconvenient to have a large screen (in fact personally I'm disappointed it's > 5") but the problems can be alleviated by software.

You can see it today by switching back and forth between Android and iOS. iOS design has not yet adapted to the larger size and is more inconvenient to use one handed (for example, the swipe to go back gesture is not universal and exiting dialogs often requires hitting a "Done" button at the top of the screen.) But as the software changes the size will become more acceptable.
It's a rough sell. It's like pitching your girlfriend on switching to an open relationship...they don't normally see the upside for them.

The best possible situation is that THEY bring it up. Make it clear you're leaving, make it clear you're going to still have time to work on their projects, and let them come to you with the idea of freelancing for them. You'll be in a much better bargaining position. And don't forget to ask for more money if you're switching to 1099 contracting (you're gonna get hit with self employment taxes, etc).
That's actually pretty neat. Good job.
I think the onward march of phone sizes into the 6" range is cannibalizing the market for small tablets, and 9-10" for tablets is the remaining sweet spot between phones and laptops.

As a long time haskeller and lover of the language this article really brings out the warts in the language.

Put Drs/Hospitals/HealthCare in place of the other car, and your body in place of your car. The analogy works very well. ACA is acting as the bank in the car insurance analogy, demanding that you HAVE to have bumper-to-bumper collision insurance.

In the car insurance case you can forgo the car and thereby forgo purchasing car insurance, but with the ACA you can't forgo health insurance.
I realized myself that copyrighted shows are supposed to enter the public domain eventually... meaning that HBO doesn't own them, it just (long term) leases them from the public. It also occurred to me that it, along with other big companies, were trying to bribe and cajole Congress into giving that property away forever, when it firmly belongs to the public.

The public has decided to revoke their privilege. If Congress hasn't codified that revocation, then this is a problem with Congress and not with the public.

What we have now is not comparable. Check out the timeline here:

https://en.wikipedia.org/wiki/Timeline_of_Apple_Macintosh_mo...

Take a look at 1995 where there were at least 18 different Mac models simultaneously available. They all had different marketing part numbers and to add the confusion, some were actually the same machine under 3 different brandings[1]. The graph doesn't show the different brandings, so the lineup was actually much more complicated than it looks.

I don't see why the preorder date would matter so much. I would think that this would be much more about manipulating the tech press to divert resources that would have been used to cover the Nexus announcements to, instead, cover the leak. If this was intentional, it would be about "mindshare," not about merely staving off a few preorders. (There are probably also not a lot of people preordering Nexus devices who would be so easily nudged into buying an iPad.)
Thanks... but the alioth benchmarks do not really measure production readiness, although they are very educational.

To me it seems that for writing high performance dense numerical code the tradeoff still is: either write idiomatic code in a horrible language, or write horrible kludges in an beautiful language. Sigh.

Would there be any "Scientific Haskell" resources available that would straightforwardly explain how to write performant code that wrangles data from one data sequence to another?
Things like this make me wonder if Windows (Server) ecosystem will be able to compete with Linux in long term.

I do realize corpo-world is filled with Windows Servers now but it seemed Linux/Docker could change this with containers as a 'standardized server app format' with super easy provisioning process.

Now since Windows will get more or less the same - Linux/Docker and Windows/Docker will compete on tools and raw perf.
I've had the pleasure of using one of these for the past month and it's been really great. I have a Chromecast that I used all the time before, but because I can cast to the Android TV (Player), I don't use the Chromecast anymore (I only have one TV).

The whole UI feels very snappy, and videos load very quickly.

The game pad feels great in my hands. No complaints there.

The selection of games on Google Play isn't huge (yet?). I currently see 16 games listed on it for download/purchase. My favorite so far is Leo's Fortune. I enjoyed it on my Nexus 5 when it came out, but after playing it on Android TV, I won't even play it on the phone anymore because I've experienced how much better the game is with a controller. I suspect that's going to be the case with a lot of games that come out for Android in the future. Touch interface only games have a lot of limitations.

Besides Netflix, you can also use Plex (PlexPass subscribers only right now) and that works pretty flawlessly as well.

I've been very happy with the whole setup and I'll be recommending it to all who are in the market for a set top box.

I moved from a Galaxy Nexus to LG G3, which is smaller than the Nexus 6 and I find it incredibly hard to use. Can barely use it with one hand and it doesnt fit in my shirt pocket, sticks out, cant put it in my pant pockets, because it will break. Its very inconvenient size wise. awesome phone though and excellent battery life.

Galaxy Nexus was so small I could put it anywhere on me and it would be just fine. Awesome to hold in one hand.

Google just excluded itself from a large market and is competing only in phablet space.

I guess with Moto X staying in the more average size space, they want to get in to phablet space, which is fine.
You should checkout IronFramework.io and nickel.rs. They are both a little farther along and try to do something similar to ExpressJS.
I agree that flash prices shouldn't be as high as they're charging but I also think you should know that they're higher than you think. Here, for example is a pretty raw eMMC module: http://www.hardkernel.com/main/products/prdt_info.php?g_code... ($49 for 32GB) and a larger one http://www.hardkernel.com/main/products/prdt_info.php?g_code... ($79 for 64GB). That's a $30 price difference at the OEM level.

You need to keep in mind that the flash storage baked onto devices is of an entirely different class to the flash storage you buy on a USB key or something. Phone storage has to perform well (it's where the OS lives) as well as survive the lifetime of the phone with near constant use 24/7. They need something a bit higher quality than what you're used to so the price is higher.
Your comment got me excited -- but I looked up the size of the Z3 "compact" and it is larger in every dimension than my iPhone 5s.
They probably aren't going to try to upgrade safely. All the latest Google apps that have updates, like Photos and Newsstand and Google+ have actually been broken and crash on the L Preview.

They are just treating it like a true dev preview, not treating it as a daily driver.

Does everyone kvetching about Apple's product line realize that they have many different product lines? And that there are only 2 iPads (which only people on HN refer to with a generation number, Apple just calls them the iPad Mini and iPad Air).

Steve jobs came back and simplified their desktop and laptop lineup from each having like 10 models to each having 2 or 3 clearly defined models. As they add phones, tablets and watches should each have only 1 model so that the absolute number of models in all of Apple's businesses stay constant?
Based on the rumors that Apple Pay is coming this weekend, I think 8.1 is likely to be released tomorrow or Friday.
2015 Ford Galaxy – Release Date
UPDATE

My friend's 3rd display just came in this afternoon. When he plugs it in and turns it on, the computer stops responding. When he turns it off, the computer resumes working normally.

Ordinarily I would scream "driver problem" at that one, but the 2nd screen did not have this problem with the same GPU and driver installation. (That one just randomly disconnected and reconnected every 30 seconds or so)

He's trying it on different computers next, further updates as events warrant...

UPDATE 2

Hooked up to his Mac. It flickers on and then goes blank.

Even running at 30 Hz on single-stream transport, it doesn't work over DisplayPort. HDMI works at 30 Hz, but DisplayPort 1.2 with MST is the only option with enough bandwidth for 4k at 60 Hz.
How many do you have on your list so far?
> There is this stream computation library

Sometimes Haskell allows you to easily implement algorithms that would be, comparatively, much more painful to write in c++. There are stream fusion libraries, and it's important to know them. You can do a lot with plain Haskell before you need to start worrying about CPU instructions. Things like linear algebra, matrix multiplication kernels are exceptions.

> Haskell FFI is painful to work

That link is three years old, and I think I disagree with some of things he says. I agree that haskell ffi is poorly documented. But he also says it is "deeply strange". Without using any extra tools, I would say it is a little laborious, but conceptually very simple. He also says he couldn't figure out how to return anything other than integers.

Think about it this way. Haskell makes no mention of how its objects are laid out in memory. If you pass a native Haskell object (a boxed int, or a struct) to C, C code will not ever be able to unwrap it without making guesses about memory layout. What Haskell expects you to do is to do this yourself: if a structure consists of an integer and a double, you define (yourself) a function that takes a pointer, and lays out the integer and the double in the memory as your C code would expect to find them there.

Then every FFI call takes the form

1. Allocate a chunk of memory.

2. Store your Haskell object into that memory, using your layout. This is what the `poke` function does.

3. Pass the pointer to a C function.

4. C function reads and writes to that chunk of memory.

5. When C function returns, read from the memory and pack the results into a Haskell object. This is the `peek` function.

5a. Quite often a C function would return a success code anyway, and the actual return value will be written to a pointer passed to the C function. This is really common.

6. Deallocate the chunk of memory.

6a. Notice that no assumptions were made about internal object layout, except that you have to know what layout the corresponding C structure is expected to have.

This might also be the reason why it's unintuitive how to return complicated objects from C. The complicated objects need to be explicitly unpacked and stored into a Haskell object. There are tools that automate this process, but the tool-less FFI is straightforward once you figure it out.

Here is the layout GHC actually uses: https://ghc.haskell.org/trac/ghc/wiki/Commentary/Rts/Storage...

This is maybe a bit unintuitive, but it makes sense to me.
As a developer for my company's internal LoB tools, I really enjoy WPF more than Winforms. I feel very empowered and, as a Microsoft shop, it seems to be really great for meeting a specific aesthetic and function for my users.

Could I do it in a web app? Probably. But it would take a lot more work for me and I'd be battling compatibility with IE7 (yes, we're still on IE7) as the corporate web minimum spec.

WinRT felt half-baked when I used it about a year and a half ago. Furthermore, I doubt Win8 is on the docket for quite some time.

WPF hasn't been the 'cool thing' for quite some time (ever?), but both I and my users seem to really enjoy what it's doing for us. And that's good enough.

> That's hardly ever true.

Even pg discussed the phenomenon, as you undoubtedly know. There's a good idea, or a news article hailing progress, or some other kind of optimism, then the first comment is a mid-brow dismissal. They are the lowest-effort comments to make; "that won't work because X isn't well-respected and Y often happens to similar teams" requires almost no research and cannot really be refuted.

The only way to refute it is by calling a spade a spade, and look what I get for doing so: having my comment twisted to be fuzzy feel-good smarm crap, when really I'm just saying "shut up and get out of the way if you don't think it'll work."
I have literally never heard anyone ever say, "I like this phone I bought, but after using it for a couple of weeks, the screen is just a little too big for my tastes."

Like, NEVER. In all the complaints I've heard about people's phones, over the seven years that we've had smartphones so far.

What I have heard is a lot of people pooh-poohing 4.7" screens, 4.9" screens, 5.2" screens, etc., and those screen sizes going on to utterly dominate smaller phones.

FWIW, a single Boeing 747 engine does about 100MW. Such an engine can be considered to "fit on a truck" for some definition of truck.

Also consider that much of the size is due to the fan on the front (which is not part of the actual engine power plant), which makes the engine's area in the plane transverse to the axis of rotation seem larger.

However, jet engines have the advantage of burning their fuel directly in the air that is flowing through the engine, which results in an extremely rapid transfer of heat to the air compared to other (this is why 10 Boeing 747 engines == 1 GW coal/nuclear plant which is "buildings" in size).

"I was just in a meeting with Microsoft and they’re definitely working on the next version of WPF. Obviously, I can’t disclose specifics, but the fact is they are gathering feedback and actively working on WPF."
