I'm not always a fan of modelviewculture, but I think what they say implcitly is very important: start with culture.

Have a culture where men and women alike consider themselves functional and important parts of your business.

Let this culture speak through your actions (specifically: offer benefits that are attractive to the kind of person you want to attract), and let both the culture and you actions shine through in your public appearance (general website, HR-specific website, job ads).

Also: pre-recruiting activities (community involvement, generally getting in touch with people) can help your visibility especially with people who are not well-connected members of the majority group. Get involved, and, as mentioned, let your culture shine through.

As they further mention, some of the recruiting practices that are popular tend to be systematically biased towards a single, relatively homogeneous group of people. See this as an opportunity to perform arbitrage on that market by talking to suitable candidates that some of the other players are ignoring.

£1500 for the mortgage, plus bills, council tax, land rent, home insurance, repairs, etc... that is around £2000 per month not counting food, travel, clothes and entertainment.

So realistically you need to earn £3000 after tax to be able to afford it, which translates to a pre-tax salary of £50k.

We are lucky to earn more than that but the vast majority of people I know would not be able to do it.

Thus highlighting the difference between monetary value and what is actually useful. It's a difference people get confused about too often - thinking that the most important thing on the planet is the economy; thinking that everything is fungible because it has dollar value. It's all fun and games until we hit resource limits of the planet. Or kill someone. Our economy sucks at pricing in the fact that while we can safely run out of tullips, we can't safely run out of clean air.
That's what I suspect, but it's crazy. The average salary in London is £27k, a senior dev will earn 3x that (I'm guessing). And that's still barely enough to live comfortably.

I guess that's the point of the campaign in the linked article, but I can't see how that will change, unless the financial bubble bursts.
Is this for the city proper, or does it take an average of the suburbs, too?

I live in a suburb of Portland, (Hillsboro) and I live a perfectly decent life making about $44,000 a year before taxes. I'm also young and don't have kids, but I would happily commute half an hour into Portland if I had a job in the city. It's not that bad of a drive as long as it isn't during rush hour.
You can also ponder it from the perspective of a state who are very keen to keep the news media as distracted as possible from what you're up to.

If this was the goal, then it was achieved admirably - a mystery was provided, and the press took the bait, and largely ignored the brewing unrest in Ukraine.

In terms of the plausibility of his theory... it's plausible. It doesn't mean it's right, but it's plausible. I've been to Baikonur, and it's in the middle of absolutely nothing, has very, very high (Russian) security, and is a pretty ideal place to disappear anything.

The one thing I think he does get wrong is that he thinks building demolition in freezing temperatures is weird. This becomes a hell of a lot less weird when you realise that in the summer, temperatures there reach 50+ Celsius, and doing outdoor work in the dry cold is vastly preferable to doing it under the blazing sun.

It becomes even less weird when you consider that Baikonur is being edged towards end-of-life, as Russia are building their new cosmodrome at Vostochny.

Thanks! It was really instructive.
Another factor is generational wealth. Most of my friends who own houses in London earn less than me but were given large amounts of money by their parents. When you have a 20-40% deposit the monthly mortgage payments become much more affordable.
And finance will pay you more than double that, and give you a 100% bonus on top of that again.

It's not about putting anyone's rights "above" anyone else's -- whoever is willing to pay the most gets the property, that's all there is to it.
Such a simple idea but so useful!

That's not the only way, though it is not bad (as proven by the prosperity big parts of the world now enjoy). Mostly, it's easy and self-balancing. But as a way for solving the problem of resource allocation, it has some really bad failure modes - like creating tons of useless, wasteful work (zero-sum games like advertising) and steering us towards making our planet uninhabitable for humans.

From a financial perspective it might make sense for a young, hungry company go after what appeared to be their most profitable market. On the other hand, by focusing so hard on serving one group, they may have failed to nurture a larger, more diverse marketplace.)

So you are putting the rights of people with more money above those with less money. It's not a natural law that this is the case, it's still a political decision.

I'm curious: what is considered "London" in this context? Wikipedia breaks down the demographics into Inner, Outer and Greater London. In each case the population has been growing rapidly, so who exactly is moving in and who is moving away?
What? London is full of new housing under construction. Many of the flats will be tiny as well. The problem (for those trying to live in the city) is that the houses will be hugely expensive.

For London in particular, the problem is that there are too many people who want to own a house there. That's why the prices are high. You can't call the place underdeveloped, it's not a lack of supply due to regulations.

If you want the prices to be lower, you need to reduce the demand.
Ie, it's not because you're paranoid that they're not after you.
I agree with the idea of the 'urban cycle'. New, young professionals are happy to share a small bedsit in a bad area if it means a high salary, but at some point in life you have to rebalance your quality of living.

That's a problem I have with London- the constant churn. Everyone is transient. Friends you make are leaving in a year or two, maybe to go abroad or to buy a house in the suburbs. Many, many of the people living here do not consider it a 'home' but a stepping stone towards their goals, and I think this contributes to a lack of community spirit and feeling of belonging. I never felt like a 'Londoner' because there never seemed to be such a thing. On the other hand, this vast diversity and anonymity is of course one of London's great strengths.

> "No Correlation does imply non-causation"

You're wrong. Random variables can be uncorrelated but not independent [1].

In general, you can't apply "algebra" to logic as you attempted above and explained below. Logic is very precise. To "prove" that `A => B` is equivalent `~B => ~A`, you use truth tables:

| A | B | A => B | ~B => ~A |
+---+---+--------+----------+
| 0 | 0 | 1 | 1 |
| 0 | 1 | 1 | 1 |
| 1 | 0 | 0 | 0 |
| 1 | 1 | 1 | 1 |

Your statements above aren't equivalent; the first is a tautology (it's always true), whereas the second is standard implication, which can be false.

My guess is we'll probably need something like graphene. Gallium Arsenide seems more like a 10 year stop-gap than a 50 year revolution. The problem is we can't get any "smaller", because we enter the quantum world and that's something entirely different. However, with graphene we can keep the transistors the same, but raise the clock speeds each generation, perhaps up to 1 TeraHerz or more, with a Moore's Law-like rate of improvement in performance.
I prefer to use the word "upkeep". Money is not something that has intrinsic value in itself. It's what we need because as a species we're too dumb to handle planetary-scale resource allocation. It's a waste we need to get what we want. But since it's a waste, it would be good to reduce it as much as possible.
Because, even at that price, the trains are still standing-room only on peak.

From a quick calculation my £4000 season ticket works out about £0.25/mile.

Better thinking
I'm 32 and I recently moved out of London when my wife and I had our first child. Although London has the best of everything, if you can't afford the best, you often get the worst. At least where we are now (Southend on Sea, in the Thames estuary) the public services are excellent, it's safe and there's a strong community.

Curious, can you share much about how it works?
London is silly. I'm a contractor on a good rate and I can't afford to live where I want around Hackney. A 3 bed is ~600k, a 2 bed ~500k.
I find this line of thinking unconvincing. There is a vast difference between voluntary centralisation from which you can withdraw at any time, and forced centralisation from which there is no practical way to withdraw without huge sacrifices.

Many socialist and anarchist ideologists are/were perfectly fine with centralisation of production, as long as decision making is decentralised, and participation is a result of free choice and can be withdrawn.

The capability of decentralisation in Bitcoin is important because it acts as a safeguard against forced centralisation and coercion. As long as the capability remains, whether or not people for practical/efficiency reasons opts for centralisation ought not cause most anarchists any major concern.
I have sort of a different experience. I just moved to London, from Dublin, a few months ago. I make a good, but not outrageous, salary: pretty close to a reported average for software developers in London.

I live in a somewhat rundown area, just outside zone 1. The rent is expensive, but not unmanageable. I have flatmates; the area feels safe; its close enough to bus and tube lines that getting around is simple. I live fairly frugally otherwise. I don't at all feel like I can't afford to live in the city, and I can't imagine having the access to the range and depth of culture and social events anywhere else.

Maybe it's that I don't have any interest in buying a home, but I feel like so much of this doesn't apply to me. Maybe it's also that I moved here from Dublin, another very expensive city, that I don't feel like it's so bad.
How wonderful! Thanks for the suggestion; I'd never have thought or heard if this rather interesting practice otherwise.
As I understand it, the problem is that new construction is outstripped by increasing demand. Hence the increasing prices. I read an article in The Economist's recent suburbs/cities issue where they said a lot of the problem lies in how people are prevented from developing the green belt.
"Or do you honestly believe"? Really? Your choice of wording is a tactic that spins the discussion in a way that people should recognise as a derailing tactic by now. It attempts to make people who do indeed view things this way feel embarassed, and it's not even about beliefs to begin with. Please stop.

You'd be even more incredulous if you had to ride on a London bound commuter train every morning. If you're lucky you'll get to stand in a space large enough that you don't have to stick your head in someone's armpit. If you're incredibly lucky, or get on at one of the first stops on the line, you might even get a seat.
I guess this indeed the most plausible theory. But then how plausible is it that no debris was found? Too much time went by, the area is too big for us to notice?
There certainly exists properties (even, anecdotally, entire streets) in London that serve as wealth-deposit-assets for rich foreigners of questionable repute. Many of these are left empty as the owners aren't in the "landlord business" and merely want to hold a liquid asset (an occupied house isn't as liquid as an unoccupied one).

There is also a story about the saudi royal family buying up a strip of houses on Bishop's Avenue (the most expensive street in London, despite being somewhat suburban) sometime in the 80s or 90s as a bolt hole, but IIRC recently disposed of.

It's clear that this produces some pressure on the housing supply in London, but nowhere near enough to account for the sheer numerical pressure (some ~800k housing units required by 2021 and the rate of new builds is way, way off that target).

Well, it's a lot more likely in my eyes that it'd be a thin client operating against a server owned by its owner. Just as safe, and doesn't involve trying to figure out how to allocate enough money on a micro scale to all your individual devices so they don't run out.
Chesterton's fence comes to mind.

Also, as Yvain pointed out in his excellent article[0], we might be fucking ourselves over big time with this drive towards decentralization and trustless systems. As we fight against corruption and abuse, we're building systems that don't allow us to coordinate even in principle. Today it's tax avoidance and buying pot on-line, tomorrow it will be untraceable trade of fissionable material and weaponized biotech.

Building trustless systems seems like a cool hack, but I think we'd be better off working on a way to improve coordination.

I think £27k is the UK average or the southeast average? I thought the london average was closer to £60k? I can't find a source for that though.
Well, all bubbles burst and things always change. Give it another financial crisis, housing crash or big change in UK housing policy (unlikely to happen before a crash) and London might calm down again.

It's many political decisions, including, but not limited to:

* Perpetual QE

* Ultra low taxes on property (council tax)

* Rules that allow foreigners to buy property and not be taxed at all if they declare themselves non-resident.

* Rules that allow tax evaders in foreign countries to stash their wealth here unimpeded.

* Lower taxes on capital (dividends, capital gains) than labour (salaries).

* A reluctance to build social housing in London.
"Hiding peripherals and memory from the non-secure world is a key feature of TrustZone"

Whenever anyone says "secure", you must ask what is being secured, and against whom. The purpose of the secure world is to run a small operating system with privileged access to hardware that the outside world has no access to. It is the ultimate in nonfree software: it cannot be inspected at all, even on the binary level, and its loading can be governed by hardware keys. I believe it's also secure against JTAG inspection although this article doesn't mention that.

To use a device with TrustZone is to place total trust in the author of the software inside the trust zone. If they want to put Superfish-style malware in there, there's nothing you can do about it.
Single earner with 2 kids living in London on top-1 percentile income here. 60% of that monthly income is going towards rent, taxes and utilities for a terrace in Zone 4, plus nursery charges for our toddler. My wife can't find a job here, as she's an ex-journalist, and not a native speaker. No tax allowances (due to £100k+/y income) and no recurse to public funds (I'm on Visa, and not an EU citizen) doesn't help either. Apparently, I supposed to be rich enough for London to be taxable on 50% of my income (effective tax rate: 41%).

Thought of buying a 2bd flat recently, but it'll take us two years of struggling for every extra penny to just get a mortgage for a very moderate £250k place.

Income means nothing in this city. Either you got your housing issue settled 15 years ago using 'right to buy' or some other form of government housing subsidies, or you somehow generate wealth on a side (obviously, not through the salary, as even £200k/y doesn't seems to be close enough), or you are going to rent until you loose your source of income (i.e. due to old age) - and then you'd probably die on a street.

An economy of landlords drawing the money from their own kids. In a few decades all that accumulated wealth will be probably burned away on anti-cancer treatments, and then heavily taxed and rented younger generation will just quit on trying to build a welfare state, throwing their lives away only to provide a comfort living for older people. Hope our grand-kids will be at least able to start from blank.

The billboard's impact is weakened by the fact that almost half of the messages are about people 'planning' to relocate outside of London.

So the situation is bad yet they still haven't left? That kind of implies that there are still advantages to living there and they haven't outweighed the disadvantages. Why didn't the billboard creators just stick to people who have moved away? Their actions would speak louder than the words of those who may just like to moan!
Not sure if you're already aware, but "bit rot" is an ambiguous term nowadays.

The original definition[1] refers jokingly to bits "rotting" as an (obviously false if taken literally) explanation of why software that used to work fine has stopped working after a period of time elapsed, actually because of causes now more properly(?) known as "software rot"[2], but the term is sometimes (mistakenly IMHO) used to refer to actual data degradation[3], or "data rot"[3]

This whole sorry tale is actually due to the related but little-known phenomenon of "sememe rot", a gradual decay in units of meaning so that thoughts and sentences that used to be perfectly coherent will gradually become incomprehensible, or even worse come to mean something different, even quite opposite, to their original import.

Anyway, from your SSD question I guess you're interested in data degradation. The best advice here is just the obvious: "always back up!" Though this doesn't answer the interesting question as to whether data degradation is more or less of a problem this year than last, it is still the best strategy.

Sure. But if we'd been having this conversation 20 years ago, it'd have been the rights of the Yuppies above the East End families, and then 200 years ago, it would have been those wealthy landed gentry pushing out the good hard working Hugenots, and so on and so forth and you still don't seem to see the irony of bearded new media workers being priced out of the same market they were busy pricing others out of a decade ago.

I'm also curious about just how many Arab Oil Barons and Russian Oligarchs you think there are, as a percentage of an 8m person city? Because right now, blaming a handful of immigrants who are buying multimillion pound properties that almost no-one else can afford smacks of racism.
