There are advantages and disadvantages to consider. Clearly monolithic repositories allow you to leverage commonality but it’s not free.

For example, single-repository environments may require you to check out everything in order to do anything. And frankly, you shouldn’t have to copy The World most of the time. Disk space may be cheap but it is never unlimited. It’s a weird feeling to run out of disk space and have to start deleting enough of your own files to make room for stuff that you know you don’t care about but you “need” anyway. You are also wasting time: Subversion, for instance, could be really slow updating massive trees like this.

There is also a tendency to become too comfortable with commonality, and even over-engineer to the point where nothing can really be used unless it looks like everything else. This may cause Not-Invented-Here, when it feels like almost as much work to integrate an external library as it would be to hack what you need into existing code.

Ultimately, what matters most is that you have some way to keep track of which versions of X, Y and Z were used to build, and any stable method for doing that is fine (e.g. a read-only shared directory structure broken down by version that captures platform and compiler variations).
It’s not as simple as that. Wikipedia says:

Some cuprates have an upper critical field of about 100 tesla. However, cuprate materials are brittle ceramics which are expensive to manufacture and not easily turned into wires or other useful shapes. Also, high-temperature superconductors do not form large, continuous superconducting domains, but only clusters of microdomains within which superconducting occurs. They are therefore unsuitable for applications requiring actual superconducted currents, such as magnets for magnetic resonance spectrometers.

IOW, we don’t have a high temperature superconducting material that’s suitable for use in an MRI scanner yet.
I wrote a comment with an example, in a reply to the commenter as well: https://news.ycombinator.com/item?id=11988075
Most of the MRI machines in existence use Helium, and they're expensive machines, unlikely to be replaced until they must be.
I use 1.07 pi; it should be the same, as it is only a matter of convention.

The short answer is that the "we're running out of helium" scare stories have always been grossly misleading, for much the same reasons that we've been hitting "peak oil" for two decades now.

Helium is available, as this story makes clear. But there's been enough of it recovered from mining & gas extraction that it hasn't been profitable to do direct helium-only exploration; this is also why it's cheap enough to use on birthday parties.

As the helium reserve declines, and known helium sources dry up, prices will rise (are rising). That will drive an increased market for helium exploration. Presumably demand for balloons is much more elastic than demand for medical helium, so I think the answer is "we aren't that short on helium yet".
It's sad to see so many people think that Tai Chi is just meditative shadow boxing. It's really more about fluid/soft and hard movements, developing an intuition for how your opponent will move and using an attacker's force against them.

I've seen people finding it very useful as an influence in HEMA where 9/10th of the difficulty lies in reading your opponent to know when and how they will attack.

It's also immensely useful for demonstrating the importance of footwork, as the last video you link to (by the English-speaking Wing Chun instructor -- even if his style isn't "really" Tai Chi) shows very beautifully.

I'll second Sindisil's comment about nested functions.

I still often do the paragraph approach, but the thing about that is you rely on the comments to stay up to date to describe that paragraph.

I prefer to instead move that paragraph into a small nested function and name it to reflect what would be in that comment. I feel function names are easier to keep up to date than comments (ie, programmers don't just read past the function names like they do comments).
Sorry for the delay, busy at work. And need to shorten things again (or else I also suffer from quote-and-rebut-itis)

> Throughout most of history working class people have owed their homes.

Not true, in the UK at least. And working class people, as you're defining them, have only been around for a couple of centuries anyway.

For example, the link below shows that in 1918, 77% of the UK dwellers were renters. Home ownership has increased every decade since, except the current decade.

Unless, of course, that wasn't a typo, and you actually did mean 'owed' :)

> Up until the 70s in the States

Up until the 70s in the States was a very unusual time, and the US itself was abnormally prosperous. It's not a good baseline. It's also not the UK experience.

> This will be a minor heresy to you perhaps, but the middle classes actually consume the majority of welfare through indirect subsidization

No, no heresy there. The middle-class sometimes wonk on about 'dole bludgers' here in Australia, but try and get them to hand back their tax rebate for whatever and you'll get a story about how somehow someone on the average wage (in a well-off country) is 'doing it tough'. However, welfare cutbacks will still affect everyone who isn't financially independent.

I guess it's going to balance out in the UK - if the Leave stalwarts get their way, all the Polish tradesmen will be shipped back home... and the middle-class won't have the money to employ tradies to fix things. Fewer tradesmen, fewer jobs for them anyway :)

> Most households also contained a cook in the form of a mother which cut down on living expenses

This bit genuinely puzzled me. Earlier you said it was a bad sign of the times that the young couldn't afford shelter. Yet you paint a society of mothers having to live with their kids in some sort of indentured servitude as an example of the good times? That multi-generation families are bad when the kids live with the parents, but good when the parents live with the kids? Odd.

Ultimately, the problem is that the referendum was won on lies that were revealed by the liars themselves. On the first day, Farage admitted that the NHS wasn't going to see the money that they advertised (and others have pointed out that the actual funds to the EU were half of the claimed amount). In the following days, Bojo said that immigration wasn't going to see significant reduction. So, the two major heartstrings, "those damned immigrants" and "all that money for ourselves", aren't going to happen anyway. Nor should one forget that a mere dissatisfaction with the government is not the same as wanting to have your country destroyed - far from all Leave voters wanted to dissolve the UK... it doesn't seem that the actual will of the people was to dissolve the UK and upset the apple/egg basket/cart that much.
How do they handle tracking dynamic objects if they are also moving dynamically? Is it just a SLAM method, where you can identify objects between frames?

The only way I have seen this done us using post-processing on object edges. There is no horizon, so it would be pretty difficult to do in real time (I.e. ~20 fps), perhaps to slow to make decisions.
I can't even process what you're saying. What culture doesn't acknowledge self respect, and one's place in society relative to others?

Certainly there are small communities everywhere (even in America -- after all, they were prolific in America's infancy) that sought the creation of a hyper-communal and idyllic towns... but... those never scale because, well, people are selfish. But still. I just can't process what you're saying. Maybe I'm blinded by offense.
That's interesting, but it had a 2:1 numerical advantage too, which does matter.

I am assuming you meant this as a figure of speech, but it is a very unfortunate one.

As for your edit:

I am assuming that the downvotes are because you express yourself in a way that doesn't help at all. The statistic being what they are you are either unware of the statistical insignificance of that number or you are but you are inflating it to make it seem more important than it really is.

Yes, statistically speaking there may be 59 'premature deaths', but that does not quantify just how premature those deaths were, nor does it acknowledge that transportation carries an enormous cost in lives over and beyond that tiny little bit extra because of these emissions.

Yes, VW did a really bad thing, yes, they should be punished. But the cost of transportation already being what it is the punishment seems to be roughly in line with the extent of the crime.

If you're really concerned about this you should campaign for us all to stop driving, that will really move the needle.
Seen a few strip malls and even one small town downtown corridor converted to government services offices.

While it is good to reuse an existing structure with a little help from zoning the land and supporting utilities can be re purposed to other uses that require good traffic qualities and location; schools, churches, car dealerships and even apartments.

I would think the unmentioned issue is, did the area collapse around the store that supported it or was this simply caused by bigger and better nearby? If its the former then getting people back into the area could be challenging and makes it much more suited to government offices or such

Not the same thing.

Randomly I'm working on some fairly awful code today that has the one redeeming feature that it divided and conquered as described in the article.

It made it fairly trivial to find the exact spot the problem was happening.

At no point reading the code did I think that assigning key values into variables along the way that were named to describe exactly what they represented and then all added up at the end was a personal quirk of the code.

That's a world of difference compared to using the fairly odd:

This is pretty standard stuff in automobile land. Unsprung weight (includes slightly more stuff than this, but same basics) is known to have a disproportionate effect relative to, say, the driver gaining a couple lbs. People don't talk about it as much as other performance factors, but this is why magnesium wheels have existed for upper end cars for a while, and carbon-fiber more recently.

On the flip side, this is also exactly the same reason why flywheels outside of automobile land, when used as energy storage devices, are hugely massive.
The techniques aren't fake, they're just unreliable outside of training.

It's one thing to pull it off against a training partner who is using a known subset of attacks and when you know they're coming. Different when you're in a chaotic self-defense situation and facing a fully-resisting opponent who will try anything to win.

You need a much higher level of skill to deal with the latter than the former. It's the same as how a really good boxer can (against a less skilled opponent) just drop his hands and bob-and-weave to avoid strikes, but an average or unskilled boxer can't afford to try fancy, high-risk techniques, when simpler tactics are a much safer way to win the fight.

That's the biggest problem with stuff like aikido for self-defense. Taking an average person and giving them six months or so of aikido training will NOT make them able to effortlessly toss around men 3x their size who are seriously trying to hurt them, and telling them that it will is selling them a dangerous lie. Even if they put in decades of training, they're still relying on relatively high-risk techniques when there are other more reliable ones.

I don't mean to crap on anyone's favorite styles. Aikido is an art form with some self-defense applications, and it's great for that. But a lot of people don't understand how hard it is to beat someone who is massively bigger and stronger than you, and it's doing them a dangerous disservice to market it to them as more than that.

I agree with your assessment of Messages and I also don't have either the FB or Messages mobile app installed.

That said, messages are still working for me in Metal (third party FB app) and in my mobile browser. Even if/when they stop working that way, I figure I'll be able to tick the "desktop mode" box in my mobile browser to set the user agent and get it that way. Barring that I can just check those handful of messages I get via my desktop computer.

I guess I just don't depend on FB messaging for anything important so it's less an issue for me. If someone wants to reach me, they can call or text and Hangouts works fine across mobile and desktop on Android, iOS, Windows, OSX, Linux, etc. for group messaging.

What this means in terms of the overall healthcare debate:

- A very large percentage of total lifetime healthcare spending is often spent during the last few days of life.

- Many of the extreme measures taken in the last days of life are extremely painful and lead to significant suffering for the patient (and rarely work).

- Even when someone is quite old, we view death as unnatural and lean heavily on expensive technology to try to push it off.

- Wrapped up in this is the authority we grant physicians. It is socially difficult for a physician to advise against "hope" that a costly and painful intervention will save a patient's life, even though the vast majority of physicians would not choose such interventions for themselves or their family members.

- Since the cost pattern is well understood and risk pools favor the old with costly healthcare needs, the young people in society pay dearly for the $50K treatment that usually fails to let an 80 year old live a few extra months.

- The simplest way to reduce healthcare costs would be to simply allow people to opt out of costly extreme measures once they are elderly, in exchange for significant savings.
Let x be a randomly chosen real number in [0,1]. What does it mean to "manipulate x's concept" or "think in terms of x"?

Do these phrases attach themselves to the real number, or to the expression language? If the latter, do you say two number-expressions are equivalent if applying some normalization function yields two equal expressions? Do you consider two number-expressions distinct if they evaluate to the same real number, but cannot directly be related to each other?

For example, let:

S = { (x, e^(ix) + 1) | x in R, x > 0 },
T = { x | (x,y) in S, y = 0 },
c1 = min(T),
c2 = 6 * sqrt(sum(n^-2, n > 0))

If my memory's right, c1 and c2 evaluate to the same real number which happens to be equal to Pi. What does it mean to manipulate c1's concept or think in terms of it? Does c1 have the same concept as Pi?

Totally disagree. Any serious development project that has an application that needs to work across iOS, Android, Mac and Windows should be sharing as much of its business logic, in C or C++ which is usable on all those platforms. The UIs of course will be platform-specific, hopefully as thin as possible, but the majority of your code should be totally re-usable.
Never heard of gitcolony before. Looks interesting, thanks! That would probably solve one issue. Then there is another one.

I try my best to keep head of master branch in such a state that it can always be taken into use in all projects. Just last week one branch of one embedded device had slight API change. Nothing big, but backwards incompatible change.

I branched test automation core and made it work with the new API. All tests looked green and things looked nice. We agreed with the embedded device owner that we'll merge that change upwards soon. Soon like in one hour or so. I rushed and merged the test automation core changes to master.

At the same time I was working with another API change with one PC app. That branch was also looking good and those changes were merged upwards in both the test automation core and in the PC app.

Now my test automation core master head was compatible with everything else but one embedded device, the one with the small API change that looked good in all tests. For some reason business did not want that change to go live yet with the device, so now I had changes in my test automation core that made it incompatible with the released embedded device.

Yes, it was my mistake to rush with the merge. But because getting those changes upwards was two merges, one in the product itself and in the test automation core, it was possible to get those out of sync. If we had used monolithic repository, it would have been just one merge and such thing would not have been possible.

Sure, not a huge thing but still an annoyance I could live without.

A Canvas to Spark and Propel Your Startup Storytelling
Current aikidoka here--ukes are generally more compliant in aikido than, say, judo. But then again the throws often have a lot more going on, and thus require some level of compliance to just learn. Pressure ramps up as one advances, but there's really never shiai-level intensity.

I mainly do aikido because it's insanely difficult (at least by my estimation having done judo and a somewhat more traditional jujitsu) and a good workout. I don't think aikido or most other martial arts are particularly good for self defense. Actual violence is ugly and unpredictable.

I read the paper, and read up about the techniques used to do that (because the paper is very light on details). I came back completely underwhelmed.

This makes (clever) use of hundreds, if not thousands, man hours of painstakingly entering expert rules if the form IF <some input value is above or below some threshold> THEN <put some output value in the so and so range>.

The mathematical model of Fuzzy Trees is nice, but this is completely ad-hoc to the specific modelization of the problem, and will fail to generalize to any other problem space.

This kind of techniques has some nice properties (its "reasonings" are understandable and thus kind of debuggable and kind of provable, it smoothes some logic rules that would otherwise naively lead to non smooth control, etc.) but despite the advances presented here that seem to make the computation of the model tractable, I don't see how it could make the actual definition of model anywhere near tractable.

Also, I dislike having to wade though multiple pages of advertising before I can find the (very light) scientific content.
