Why not just use straw, instead of carbon fiber, in concrete? Straw is comparable to steel. Chopped straw is used for stucco, but it can be used in reinforced concrete too.
It is hard to calculate amount of straw, which is necessary to reinforce concrete, because it strength varies, but it cheap, so just triple amount of straw.

It's not a fix both cards and ATM's have to serve the lowest common denominator you can't just replace billions of cards and millions of ATM's every few years because of skimmers.

The labor to replace skimmers is already not an issue skimmers do not last for years, or even weeks most of them have a battery that only lasts for a few days and they are put at strategic locations usually hot spots around big venues or events.
You basically decided to "believe". I'm curious if you feel you "lost" some parts of you that you liked.
Personally, I think you do deserve a second referendum. The remain/leave map shows a clear border. Northumberland votes out. North of that, its all remain.

The biggest thing to me is that many in the leave camp used very similar arguments against the leave camp in the Scottish indy ref.

That and the EU/better together camp said Scotland wouldn't be part of the EU if they left and should therefore stay.

Note: from Manchester. Voted remain. Don't see the SNP as the national threat they're portrayed to be.

AFAIK any deal has to be negotiated and ratified by all member countries. What are the chances that all members will be inclined to offer UK a better deal than it had when it was a part of the union?

I'm only marginally impressed. For example, a decline in frozen meals with an increased in fresh prepared meals isn't necessarily indicative of eating "better".

I've been encouraged by Large Food winding their way towards better boxed foods, at the same time, some categories of "bad" food have remained fairly stable.

And I suppose a 10 gallon drop in soda consumption is great, but... it's still at ~40 gallons a year?!
Another language you might consider is Nim which is more like D because it doesn't have specific selling point like Rust. It's very flexible and reasonable though and Python programmers will feel there immediately at home. You have GC there but you might opt out of it and/or let it run at specific times and for specific amount of time to manage gc pauses.
Who Will Build the Next Great Driverless Car Company?
I think "JavaScript: The Good Parts" is outdated now, in particular the way it advocates handling object-oriented programming and inheritance with a "roll your own" method. It was great for its time, but especially with the advent of ES2015, modern JavaScript is going in a different direction.
That's really interesting. There are a lot of advantages to this kind of rebar apparently.

The website also says:

> Basalt rebar does not conduct electricity

Which got me thinking about electrical codes. In some cases, a concrete building's electrical wiring system uses the rebar in the concrete structure as an electrical ground.

But, I guess for buildings constructed with basalt rebar, conductive copper rods would have to be specifically built in separately, for purposes of electrical grounding.
Cameron announced the referendum as policy choice in 2013 and at least after the May 2015 election it was clear it would happen. Therefore this was a long time coming. Has any other European country started with a referendum process in the meantime? Do you think just because the UK voted out, suddenly a stampede of referendums will begin, even though it would be much smarter to wait and see how things turn out in the UK? "Fantasists" hoping the other side will crumble exist in both camps... (Let's not forget that Cameron was campaigning for IN. In the future, the only government who would call a referendum must be campaigning for OUT - nobody else would take the risk after what happened in the UK)

I also assume it to be a marketing stunt
This article makes an interesting comparison to ancient Roman concrete. While the Romans built a tremendous amount of infrastructure in concrete, survivorship bias means that the few bits that have hung around are seen as some sort of superior quality to Roman understanding of concrete.

However, if you go to Rome, most of the surviving bits are millions upon millions of stacked and mortared bricks, and most of what has survived are uninteresting walls. [1] For some reason, our collective memory of Roman ruins is that they're all aged concrete or stone. But when in Rome, you end up seeing lots of this [2], which when built probably had a layer of facade material on it.

And it makes sense, stacked, weather resistant, often covered in a prettier facade, baked bricks should last more or less forever until the elements wear them down.

The widespread reintroduction of concrete as a building material really didn't happen until around the turn of the 20th century. And reinforced concrete didn't find widespread use until a few decades after that. Not particularly confusing, the first generations of buildings built with these fairly new and only partially understood materials are the buildings that the author is mostly writing about.

The real culmination of exposed, reinforced-concrete-everywhere, finally happened in the 50s with the advent of the eye cancer called brutalism. Today a tremendous number of brutalist buildings today are absolutely falling apart, and I blame that on a lack of understanding of how reinforced concrete should be used and the availability of more modern materials and perhaps an overenthusiasm and misuse of materials where they shouldn't have been.

But still, if we fast forward a thousand years, there's bound to be a percentage of those structures still around and survivorship bias in the future will lead some to speculate that the engineers of the 20th century were geniuses unrivaled by any in the future.

I haven't been a practicing engineer since 2007 but if my memory serves me well, to avoid problems of corrosion one often used method was to increase the cover [0](distance from concrete surface to top of steel reinforcement using spacers). I can't see it mentioned anywhere in the article, will probably have to re read it...

"Let's let humans do more human (and humane) oriented tasks."

The definition of "humane" keeps shifting over time and will always be a matter of perspective.

To share a personal story, my father was unemployed while I was in college. Within a few months he looked like he had aged 10 years. Several months later he took a part time job as a landscaper and he started recovering.

I remember coming home from college once, driving to his work site and watching him push a lawnmower until he had a break in his work. This was a man that used to wear a suit and tie and commute to the city every day. Yet as I watched him push a lawnmower, I never felt more proud of him. He introduced me to his co-workers and it was the first time I had seen him smile in nearly a year. Several months later he was able to find gainful employment.

One could argue the isolation and lethargy caused by long term unemployment is more damaging mentally and physically than most labor intensive jobs. Moreover, society needs rungs in the ladder of economic advancement and it is human nature to find value in work and being part of a team.
I don't think robots change anything. Robots increase efficiency of human workers, they don't replace them entirely. Netflix and Redbox are highly automated, but they still have human workers; just fewer than Blockbuster did.

Robots that don't need humans is science fiction for the foreseeable future. They are not producing output from nothing; they are just tools that amplify the productivity of human workers.

This has been happening for hundreds of years with new technologies that improve efficiency.
Does the International Building Code that many jurisdictions in the US use help here at all? It's revised every 3 years. But I could also see it being overly conservative and holding back local innovation.
See infinite8s' post above. The "Engelbart's demo" mentioned is called The Mother of All Demos, which you can find by that title on youtube.

I have to admit I never really got further than the first 5-10 minutes or so. My first computer experiences are from the late 80s (and indeed didn't have a mouse) but this demo is so old, I kept having to mentally translate for myself which bits might have been new or ground breaking, and which just plain archaic. I keep meaning to watch it in full some day, but the first bit that I saw, I keep feeling I'm missing something important. People are lyrical about this demo (hence the name!), but I don't quite feel it or something. Then again, while I appreciate the great work of engineering that went into it, I'm not really one to sit down and watch a documentary about the moon landing program either.

Maybe somebody here knows a good link or article about The Mother of All Demos that explains which things I should be in awe about and why they were so novel then?

Part of it kind of looks like a simple database table system, which reminds me of a stupid story from my childhood. When I was young (~1990 I guess), I was playing with the MSX BASIC on a friend's computer whose family had a farm. They wondered if I could write anything to keep track of their cows or something--sure thing! (though I really preferred to write graphics code, later joined the demoscene, way more fun). Now I had no idea about business or their requirements (let alone requirements engineering), so I just wrote some whatever that let them enter data, but in the back of my mind I wondered how this was going to be useful for anything. Neither did I know (yet) how to actually save the data so it'd be available after reboot, which was probably a big reason for my doubts. And they were still impressed (that it could repeat names of many cows, I guess). I never finished it (nor any idea of what "finished" would mean).
But "no connection to" isn't synonymous with "not a descendant of"...
I did not say that it will have zero potential security applications.

What I'm saying is that its current threat model also defends against any access by the owner of the machine, even though that is not necessary to achieve application security.

Not even boot time configuration can override any of it. So it is unnecessarily user-hostile because it can be used to implement DRM and similar schemes where the user has no control over the execution on his hardware.

It does not provide an escape hatch when it should.
> 0^0 is also saying 'start with zero, then multiply it by itself ... Wait, on second thought, don't start'

The same is true for any other integer: "2^0 is also saying 'start with two, then multiply it by itself ... Wait, on second thought, don't start'" You don't multiply two by anything.
How about 1/(x * ∞)?

Only works if you allow (0 * ∞) = 1, which is admittedly quite shaky.
20-somethings at Wall Street and City firms are making billion dollar trades--ones where even a small amount of risk can yield huge losses. That takes an appetite for risk. Those firms have pipelines funneling in the top graduates from the top schools. They've got access to (rare) talent. They've got the connections with individual and institutional investors that can raise billions of dollars on tight timelines to finance mergers, acquisitions, or expansion. That's access to capital that could move but isn't necessarily going to. And they've got a well-developed supporting infrastructure of accountants, lawyers, and analysts helping to keep the gears turning.

You can't easily recreate that somewhere else.
Brexit Reflects EU's Failure to Create a European Identity
Most of those countries did come under, and were maintained under, British rule because of violence.

But I don't think it's accurate to say that lots of them had to be violent to get their independence. The British largely gave that politically.

EU reveals new 'migrant passport' deal on referendum day
A short survey....
We can already define abs(x) as sqrt(x^2) = (x^2)^(1/2).

sign(x) follows naturally as abs(x)/x.

The step function is a bit trickier, we can solve this with 0^0=1.

Begin by noting, that to construct an arbitrary step function, all we need is a function f such that:

f(x) = -1 | x<0
f(x) = 1 | x>= 0

By composing this basic step function, we can construct an arbitrary step function. We can also note, that sign(x) comes very close to this definition. The only problem is that sign(0)=0.

To work around this, we need a function, g, such that:

g(x) = 1 | x=0
g(x) = 0 | x/=0

0^x comes close, but is not defined for x<0. To work around this limitation, we can take g(x)=0^(x^2).

With this, we find that f(x) = sign(x) + 0^(x^2), satisfies our initial criteria. By composing functions of the form `a * f(x + b)`, we can construct an arbitrary step function.
Super fast, and lightweight TypeScript 2.0 boilerplate that export a single file
Which is exactly why I didn't much like Juncker's agressive reaction to the Brexit vote. "This is not going to be an amicable divorce" was pretty much the first thing he said. This kind of hostility towards the result of a democratic referendum is totally uncalled for, especially if the EU wants to pretend to be a promotor of pacifism in Europe.
"Is it possible to define a step-function in terms of this result?"

It might be possible to define it in terms of the semi-arbitrary choice of what 0^0 is, but that's generally mathematically unsatisfactory, almost certainly leading to no non-equally-arbitrary insights.
Of course, until you know about the brain plasticity and how it decreases with age. So it becomes more "fixed" with the years.

It's true, there is no such thing as personality. But then, why do recruiters want to know about the "profile" of a candidate? What do they talk about when they want someone who is "at harmony with the group"?

If we could really change as we liked, we would not talk about personality. People will always carry a baggage of learned behaviors with them. The sum of this is called personality. It can change of course, but in the "brave new world" that we live in, the incentives to do so never appear.

Hey, thanks for checking it out! Glad you were able to see the usefulness of it :)

I agree that staging/pre-release testing is really valuable. We want to make sure those uses-cases are supported and just as easy, ideally hooking into CI, code deploy, etc. I'll have to think about how I can re-word this a bit. If a staging site or internal service isn't behind some firewall it will already work; I'll make that more clear as we add better support for these workflows. Good points.

Monitoring uptime of any endpoint is really easy to set up! Just type it in and set a schedule. 200's are default, but you can set any status code. For me personally, I like to set up a lot of tests for 'admin-only' endpoints (eg, asserting that unauthorized requests are denied). And I agree, that's a big improvement over some of the more basic monitoring tools.

Thanks again for the feedback. We're hoping to add some more assertions this weekend, so check back up in a couple days!

This article is full of FUD. What is the alternative? All these reinforced concrete problems are well understood and studied. if proper construction and design codes and maintenance guidelines are followed these structures can last a very long time.

In europe we have EuroCodes that account for this problems and to my knowledge concrete cancer is not related with steel corrosion but with a long term chemical reaction between some aggregates and cement. Remember that concrete is cement with sand and stones and the hardning chemical reactions are complex and can last for decades.
You're paying more for the project but spend less on construction. And construction is the expensive part, is it not?
More realisticly zero steel reinforced concrete structures will survive, but other types of buildings might. The house I grew up in for example is pushing 300 years old. That's still a long way to go, but the older it gets the more likely it is to be preserved. A 90% chance it survives any given 50 years = 2-3% chance it makes 1900.
Most basic income recommendations are somewhere south of $1,500-$2,000 a month.

But no, every citizen qualifies. That's the basic part.
There are two scenarios that I can imagine:

1. The Swiss model: The UK will try to achieve bilateral agreements with all EU member countries (and ALL other countries that they didn't need to deal with before because they had a deal through the EU).

2. The Norwegian model: The UK will make a single deal allowing full access to the single market and transitive access to other markets through the EU (basically keeping the status quo).

Both options have some things on common: Any kind of deal with the EU or EU member countries will require the UK to still follow all EU regulations (just as any other 3rd country who want to do business in the EU). Many countries that currently have deals with the EU (including the US) already stated that they won't engage in negotiations until EU/UK deals are finalized. That's leaving the UK in a dangerous state of limbo.

Back to option 1: The Swiss have 200+ bilateral agreements with many countries in the world. They worked on these agreements for the past century. UK diplomats stated that even if they work full time on new trade agreements. achieving more than 1-2 deals per year is not realistic. A simple problem of diplomatic manpower. You can't do in 1-2 years what the Swiss have done in 70+ years. For comparison, just think about the amount of time put into negotiation TTIP. There's no respectable political scientist I know of, who would consider the Swiss modal a feasable option for the UK.

That leaves option 2: Norway pays roughly the amount of a (full) European membership fee to get full access to the single market. They pay that only for access to the market. The have to abide by all EU regulations without being able to vote on them or any other kind of influence. It is still a good deal for them. The UK currently pays a reduced fee PLUS they profit from EU subsidies (reducing the net amount of money payed even more). The UK won't be offered a better deal than Norway. That leads to the UK paying A LOT more without receiving any of the benefits or having any say in the regulations they still need to follow. The UK would still need to let EU citizens into their country and allow them to work because that's part of the deal and the UK actually needs immigrants. The UK will take this deal because in the end membership fees don't matter that much. The 125b pounds the market lost in a single day equal 15 years of membership fees. So the "leave" people didn't seem to care about that too much.

Here's a third option that I'd put on the table: Whoever comes after Cameron receives a vote of no confidence leading to new elections. Respectable parties will campaign with "If you vote for us, we'll ignore the referendum." Problem solved.
The 6502 and Z80 are both still popular in embedded applications, although I think the 6502 as a SoC core far exceeds the Z80 in volume. My monitors, mouse, webcam and keyboard all have a 6502 core in them, as does the NES, whereas the only devices I have that I know for sure contain a Z80 are an S1MP3[1], a Gameboy, and a TI-83.

Personally I prefer the Z80 too mainly because of its more powerful and organised instruction set[2], and the fact that it's the ancestor of the 8086, although the 6502 is definitely a simpler design (which is probably largely responsible for its popularity.)

I think it is a great day for the power of direct democracy, individual impact, and subsequent accountability for ones voting decisions.

The old England introduced to the world of kings & dictators, the Habeas Corpus and Magna Carta.

Now, the UK of 2016 had shown that the voters -- can take the decision power back.

The so called 'representative democracy' is no longer representative, it is, instead -- a 'Placebo' democracy.
Where the voters are mislead to think that their opinion matters.

And it is the 'leavers' people of UK, the voters who are described on this forum as the 'old and un-educated' --
are the first in Europe, to recognize that they were sold a Placebo-democracy.

The vote to leave is the first chapter in the modern's world Magna Carta.

And I congratulate the people of UK.

I'm not in construction or an engineer but when I was watching Mike Holmes he said the "code" (building code) really means minimum building code. I had never really thought of it like that before it was a good point why strive for minimum?
