The most expensive wooden floors have the end grain exposed facing upwards and this is then compressed down, much like the top of a good quality butchers block. Those floors are just about indestructible.

The heavier such floors are used the stronger they get!

The wood in the article is compressed crosswise to the grain (so they get thinner rather than shorter), using the original planks as the raw organic material to produce an engineered product that has relatively little to do with the original wood.
While this is very impressive the process does not sound cheap (it is time consuming and will produce quite a bit of toxic waste) and the way the article is worded leaves it ambiguous of the strength increase is relative to the original base material or if it is on an absolute scale using the same cross section.

The article states the result is 10 times stronger than the original after being compressed to 1/5th of the size, making it effectively thinner, lighter and stronger at the same time.

It appears that the increase in density is where the writer missed the fact that reducing the cross section but leaving the amount of material the same does not result in an increase in strength on an absolute scale, it merely means that if you then laminated five of the densified planks back to the original cross section the result would be 11 times stronger.

But then you'd lose much of the weight advantage.

So I suspect this is either a space or a strength gain, but not both to the extent the article indicates.

In the previous century there was a lot of research done on strengthening wood including gamma radiation and all kinds of other treatments, but none of those ever made it to very high levels of industrial adoption.
The Dutch police issued 9.2 million traffic fines on a population of 17 million. Most of this is a fully automated system from connected speed traps, to an 'invoicing system'.

I broadly agree with you, but I think your being a little bit harsh. If the material is sufficiently robust to environmental conditions, then there is room for a strong, directionally biased material. It just won't broadly replace steel (or other alloys). It could find useful niche applications.

If its environmentally stable.

For example, carbon fiber has so many other nice properties that we'll put up with its directional strength and weave it.

Really, this isn't a bid to replace steel or al, but a bid to replace carbon fiber.

Good read. The model validation is a great idea. Interestingly it will be done automatically in asp net core 2.1 for controllers marked with the new 'ApiControllerAttribute'.

One pet peeve is the unnecessary usage of 'IHttpContextAccessor'. I prefer to register the 'HttpContext' as a scoped dependency, and then use it directly wherever possible (i.e in transitive and scoped dependencies).

The reason being theres nothing to help the developer not accidentally hold onto the 'HttpContext' from 'IHttpContextAccessor' for too long, where as it's harder to misuse the scoped 'HttpContext' now that asp net core 2 checks the dependency graph for captive dependencies.

So in this example if the 'ApplicationUserManager' was accidentally changed to a singleton at startup then it would silently cache the first user and serve it for all requests. If you depend on the 'HttpContext' directly that's not possible for any of it's dependents as long as the 'HttpContext' itself is registered properly.

I think they meant "register" which is a valid linguistic term applied to this kind of thing.

Engineered wood has been a thing for over 100 years. Wood has a lot of desirable properties that make it a good construction material (fire resistance for instance is much better than steel).

This article is definitely missing the wood for the trees to some extent, but it is an interesting development and even if the gain isn't going to be quite as large as indicated and there are some serious questions about whether it will scale or not that does not mean it isn't interesting research.

But I agree with you that this is not exactly around the corner for mass production, a whole pile of problems would need to be solved and after they are the product may well end up not being economically viable.

> Each SmartBroom has four sensors in the broom head that relay data to a small display unit. Hamilton took one for a spin down the ice, and the data was instantaneous — line graphs along with a slew of numbers that showed his force in pounds and his stroke rate in hertz. Hamilton also pointed to a figure that he described as his “sweeping performance index,” or S.P.I., a metric that combines power and speed in one easy-to-digest figure.

Is there an obvious true way to reach that SPI metric? Is it possible that optimizing for the broom-provided SPI gives you non-optimized performance? I would assume that you would need temperature measurements from the ground/ice since the article implies that's the function of sweeping:

> A quick primer on sweeping: It is important. The science behind it is much more complicated than people think. The simplified version is that sweeping slightly increases the temperature of the ice while creating micro-scratches on the surface. The result is that players are better able to control for distance and trajectory as the rock travels down the sheet. The sport hinges on precision, so every brush stroke counts.

The only company that understands it right is Apple: the DPI is about same across all of the non-Retina laptops, yet the resolution varies.

Define "stronger"
This is most definitely not a language. The language is Greek, as the article also states: "It’s the same as modern Greek — the grammar, vocabulary, and sentence structure all remain intact — but the sounds come out in high-pitched musical notes." So you're just encoding modern Greek in a different way.

You could also call it a register (as the article does) and group it with shouting and whispering, I don't completely agree with that assertion but either way it's most certainly not a language on its own, it's a way of speaking Greek.

> written language which is an encoding of language sounds

That is absolutely false. Written language is _not_ an encoding of language sounds. The International Phonetic Alphabet (IPA) is, but there's a pretty long way from written language to IPA. Written language is a beast of its own and it's lagging way behind spoken language, but it's not an encoding of language sounds. It's a way of encoding language, but phonetics and phonology has nothing to do with it.

To give an alternative viewpoint on the CEO, I doubt he was upset. He probably meant to be teasing you, but he's an immature CEO who doesn't realize the effect his power has over subordinates. i.e., he was trying to joke around with you like you were his peer, but didn't realize you might interpret it differently given the power dynamics. He's definitely an idiot, but it sounds like he's more guilty of not realizing his position in life than he is of being actively malicious.

Julia v0.7.0 Release Notes
I agree, I got the same feeling from this. Furthermore, one might argue this is how it all went along anyways:

- Some people start this website Funny or Die

- They manage to get some money from it

- They get a lot of traffic for free, because of Facebook and their sharing model

- They hire more comedy writers

- They feel entitled to be paid for their work, because apparently, it works

- Facebook changes how they link to websites

- Less people visit the website, less money for them, maybe because less people actually care about Funny or Die. Entitlement to get paid to be a comedy writer stays

- Whiny post about evil Facebook (and about how brainless people are that they stopped visiting Funny or Die directly)
>The title is completely false.

No idea why you claimed that. What is completely false is your claim, by the sound of it. Did the title claim anything about properties other than strength? No. I think you may have meant "The title is misleading (although literally true)" or something.

I do not know of a good Cross DB solution. It may be more elegant to check specific exception types for the DBMSs that you do use. For example, MySQL would be:

>If you're doing something which is actually new, like PhD methods research, you need to be writing a lot of stuff from scratch.

Sometimes you also reuse a lot of stuff, it depends. For machine learning in particular, almost everything uses some sort of gradient-based optimisation algorithm. In these cases, it is very useful to have an automatic differentiation library. My coworker said Julia has about 3, IIRC, and until an amalgamation of them is merged into the standard library Julia isn't completely ready.

I'm just trying to understand this better.

> 1. I need a read slave. With MariaDB Galera, I can slave a database of a local master, but Cockroach AFAIK can only do master master. Adding another node to a cluster that will just be read from seems like a lot of unneeded overhead, and can cause massive issues if there are sync issues.

I don't know whether CockroachDB can do this or not, but there's no reason raft followers can't serve stale reads. Given that, I don't understand this concern.

> 2. WAN sucks. Where I work, I've seen mysql slaves get hours out of sync due to packet loss. With a centralized system, I don't have to worry about reconciling data. If every site can accept data, then I have to assume that every site will remain in sync. If Site 1 gets out of sync and/or stops transmitting data, another site could make further changes to the record in question causing issues. Some places this is perfectly fine, but dealing with transactions of counting clicks, I do not want to be dropping data or running into conflicts.

The whole point of CockroachDB is that you never see inconsistencies (at least not without opting in to it). But if you are unable to talk to any of the other replicas then you would have to be dropping data. You don't really have a choice here, if you have a network partition, pick unavailability or consistency. This isn't something Galera can fix either.

The first three are not the deciding factors. Other platforms are still 10-100x more memory efficient even though they share the same disadvantages as the JVM.

Your fourth point is the primary reason.

The GC in the JVM is set to try to waste as much RAM as possible. If you tune the GC you can get a big improvement and the standard Java Frameworks are bloated and slow as hell.

In my opinion it's a platform that is bad by default and simply isn't worth using but companies don't care and just buy more RAM.

Ultimately, whistling is just the emission of sound. Given that we get by with throat-sounds, I'd bet that whistling language could be sufficiently developed to be capable of expressing complex thought. Both speech and whistling are just moving air.

The CRPG Book Project – Sharing the History of Computer Role-Playing Games [pdf]
I read the article and then listened to the whistles. Surprisingly (since the article said otherwise), they were rather intelligible. They don't use one whistle per letter, which would have been weird, because you don't just say letters when talking (like "aitch ee ell ell oh", you just say "hello").

Similarly, this just seems to be taking the cadence of speech and whistling it. I listened to the proverb whistle, and it "clearly" says "η ζωή είναι πολύ ωραία όταν μπορείς να είσαι αυτάρκης", which I definitely wouldn't have gotten if I didn't know what they wanted to say, but which is different enough from the English translation to show that I could actually derive information from it.

Overall, I don't think you can actually hold a conversation in it, it's basically like taking speech and encoding it in low-bitrate audio. Lots of nuance gets lost and you're left with the low-entropy signals, which are hard to disambiguate unless you know what they're saying.

Health Benefits of Your Own Urine
One of the cool things about ASP.NET is how many different ways there are to get things done. There is a ton of stuff in there, and you can pick and choose the bits that make sense for your project.

In the old days, that meant you could toss out all silly drag/drop, faux-stateful garbage they put in to make it so you could build webapps like they were VB6. Thus, leaving behind a really good compact MVC framework for building webapps (long before they came out with something actually called MVC that wasn't as good at it). Now it means that I can read this list and not see a single technology I've touched at all in my 18 years of build stuff on this stack.

Personally, I tend to disagree with the author's approach of pushing routine stuff out to the realm of "magically happens behind the scenes", in favor of having common base classes for my page handlers that can be explicitly told to do those things with a little Initialize() method at the top of the handler. That way, when something goes wrong I get a breakpoint looking at my own code.

I like control, so the idea of voluntarily putting something in place that could magically shove its way in front of my code and whisk the user off to an error page just smells wrong.

But again, it's cool that the stack gives us the option to do so if it fits our style.
