> "If you can't explain it simply, you don't understand it well enough." is my new favorite Albert Einstein quote.

It’s also one of his more moronic quotes. Certainly on a very abstract, dumbed-down level everything can be explained simply; sure, if you cannot give your parents a rough idea what you’re doing, you might want to look into more examples. But there are plenty of things which require a very extensive basis to be understood thoroughly.

For example, it is very easy to summarise what a (mathematical) group is and for anyone with a basic understanding of abstract maths, it will be understandable. It’s also very simple to find some examples (integers with addition, ℝ/{0} with multiplication etc.) which might be understandable by laypeople, but you will either confuse the latter or only give examples and not the actually important content.

Further, when you have “simply explained” what a group is, can you go on and equally “simply explain“ what a the fundamental representation is and how irreducible representations come about? You just need a certain level of knowledge (e.g., linear algebra) already and not every paper can include a full introduction into representation theory.

Google Translate can't handle even perfectly idiomatic Japanese. It's so bad I had to write my own translation aid software (shameless plug: http://ichi.moe).

For example, Google can't handle an extremely common Japanese word なんて. It translates it as "Nantes" (the city in France). Even though the city name would certainly be written in katakana and not hiragana.
What makes you think it wasn't a very good reason? I think most problems of that kind boil down to economic issues. In some cases traditions might live longer than necessary (original reason has ceased to exist), which is another problem.
The divorce rate was likely lower for many reasons not involving diamonds.

> "... I'd simply take it to one of the many nearby Apple Stores, ..."

Which hooks up quite well with the aformentioned image of apple being more of an urban phenomenon. The only apple stores around here sell apples - and other fruit. The 'nearest apple store' would be about 70 km to the south, I guess.

In contrast, the USB port on my laptop is about half a meter away from me. Fixing an Android device would take me a few minutes - flash, reboot, restore backup. Having an iOS device fixed would take a significant part of a day, if not longer.

In other words, if you a) live in an urbanised area which b) sports apple stores you might be able to get your problems fixed. If you live elsewhere you'll be better off fixing those problems yourself - assuming you have the technical aptitude needed to do so.
"Compared to other "password keeper" programs, CryptoTE does not force any structure upon your data: it works with plain ASCII text and does not require you to fill in grids, key-value attributes, descriptions etc. Encryption is transparently performed..."

This is the reason I wrote Encrypted (https://github.com/srpeck/encrypted) - a single 21KB HTML file plaintext editor that uses SJCL to encrypt all data persisted to localStorage or disk.

I think the bar is a LITTLE higher now. If I could add one skill, its being able to read math language. It's a great skill to be able to read about a new technique on arxiv or a blog and be able to understand it beyond the surface level.

In fact being mathematically literate is really the bee's knees. Its why I suggest anyone in a stem undergrad to take their math department's Real Analysis or (my favorite) Abstract Algebra. The content is rarely relevant any jobs, but then you'll be able to teach yourself almost anything in the future.
I don't think London's rental market problems can be solved by startups, at least not beyond what's already been achieved.

The Deposit Protection Scheme was introduced in 2007, and that made a huge difference. Landlords could no longer expect to steal deposits.

There's already schemes to license landlords renting a "House for Multiple Occupancy", whose definition varies by area. Typically, it's 3 or more people who aren't related to each other. This should be extended to all landlords.

I lived in an illegally converted flat for a year, though I didn't realise it. At the end of the year, an inspector from the council appeared, and said there shouldn't be a "37A", "37B", "37C", but just a "37". The house had been converted without planning permission _fifteen years earlier_.

3 million Londoners weren't born in the UK, and in my experience are less aware of the rights they do have. I don't know how to solve that one.

But 39% of Tory MPs, and 22% of Labour MPs, are landlords, so I don't expect the situation to change. [1]

Having recognized the fact that scarcity and value of diamonds are almost completely company made constructs, I did not get my wife an engagement ring, but I did get her a beautiful wedding ring (non-diamond of course). Having a close mechanical engineering friend involved in the business of artificial diamond manufacturing, helped make the decision easier as well.

The money saved by this and by having a small wedding, made putting together a deposit for a house, far easier.
I've been using Kotlin for work (I'm a PhD student, so work is to be understood in a peculiar fashion) and I'm really liking it.

It's a much needed upgrade to Java whose fundamental advantage is what I'd call "crispness": you can write terse code that is actually understandable. In particular, the notion of inlining closures allows for efficient functional programming and great DSLs.

In comparison to Scala, Kotlin is much less advanced, but much much simpler. Like said earlier, it's easily as terse as Scala. Scala, however, is much more expressive (what I'd give for typeclasses...) and that sometimes hurts in Kotlin as it does in Java.

There's also Ceylon (JVM language by Red Hat) who is seemingly in the same niche and which I very much wants to experiment with. From what I've read so far, Ceylon seems conceptually more elegant and more powerful than Kotlin. The open question is whether it can match Kotlin's crispness.

It feels a bit early for a release however. The compiler is still completely wonky. Inference sometimes fails on things that should be completely trivial. It is particularly bad at taking return types into account. It's fully usable, but expect to work your way about some linguistic unpleasantness (or outright bugs).

Also, for some reason, Kotlin seems big in Japan.
There's just one thing I wanna see changed in Tumblr.

The usernames on a post are:

1>The person who just shared the post (in bold, top of post)

2>The person that 1 just shared it from (just under 1's name)

3>The actual content of the post

4>The original author of the post (grayed out and in slightly finer print)

For a site that places a lot of importance on artists (and where you can often find complaints of "art thieves"), it's kind of puzzling why the actual creator is given so little importance compared to the person who clicked the "share" button.
>Design should be better, discovery system should be better(more like on medium/reddit), it is also ridiculously slow on tablet

We see comments like this all the time for social platforms that are in a mature lifestage: Digg, Reddit, various other forums, etc

These found success with their "poor" design and discovery, why change now, and what evidence is there that such change would alter their course?
Will the rate stats include the history of rent increases? Or for that matter how the landlord behaved when the previous tenant moved out? Rental market in London is an absolute car crash. Most of us don't even bother doing anything about how we're treated and so the next tenant will have no way of knowing what they'll encounter within or at the end of their tenancy. I hope this app will make some difference but the best fix to London rental market bug is to move out of London.
Many European mobile contracts allow a bucket of roaming data (400MB per month for me). Not sure what's the status for prepaid SIM cards that tourists from outside of Europe would likely have.

And 95% of statistics are made up, too. It's hard to say what Tumblr actually consists of.
Wow... I would truly appreciate if you could share a bit more about your specific setup. I found myself working on a new project yesterday that I was really really excited about, until I saw the costs to transcode video.

How does doing all this in-house compare price wise (say, per minute), compared to using elastic transcoder?

Edit: The ultimate lowest cost I can find is $0.0125-0.015

It also supplies the degree holder with a social signal which says: I can buy into the establishment. I say this with my newly minted BSc. in hand. In the process of obtaining it I realised that at a minimum, all you have to do to get a degree is satisfy the course requirements. I took some shitty courses that I knew were largely wastes of time [0]. Doing them anyway equips me with proof (degree) that I can submit to a system I disagree with if I have to. This excessively cynical attitude is the product of being a cog in a massive degree making machine whose graduates are on average, I'd say, mediocre [1].

I must admit i'm considering investing, depending on what other details are announced when they are announced.

What i'd really like to see is a London centric bank (or perhaps building society), one that understands the rental market and the ownership market. It's insane that people (myself) pay more to rent somewhere than to buy somewhere, yet are hamstrung by the fact that either they don't earn enough to afford to buy, or don't have a deposit to afford to buy.

I thought Metro Bank might be that, but i think they're more focussed on expanding outside of London.

How did they figure out where the black holes are?

with just 2 "ears" I'd expect to be only able to determine a circle, but here is the picture they released: http://www.dailygalaxy.com/.a/6a00d8341bf7f753ef01b8d19e59ad...

Do i see a warped circle, or the bottom part of one? In the latter case I wonder how they found out.

Are the L-shape sensors capable of seeing some direction depending on which way the phases shift first/last?

If you'd build one of the sensors in reverse you'd see a reversed signal, no (and in between other amplitudes)?

Given that they will have optimized the orientations of both stations this is probably how it worked and I'm seeing just part of a circle, right?

That one lonely blob might be an unlikely mirrored version?

>I also don't see how feedback/review or properties is going to be useful.

If there were a public 'issue tracker' for properties that would be very useful. Seeing how quickly and how well Landlords respond to things like a broken heating system or mold would be invaluable when finding a place to live, and having this information made public would also kick some of them into action.

Similarly, if renters could have their payment history tracked so landlords know that they pay on time and that previous landlords didn't have any disputes with you, that would be invaluable.

Where are the lessons learned from these integrations? We are currently 15 years into the dot com malaise and there does not seem to be good project managers or decision makers who recognize what they need requirements-wise and then what it will take to bring a person/team/company into the fold.

Hate him or love him, Zuckerberg has a team that integrates. Instagram was brought into the fold at Facebook and there has been little to no rumblings across the board from the users to the developers. WhatsApp has been left alone at Facebook and I still use it.

The integration teams exist, but the processes and/or politics are killing the integrations at a lot of companies.
Thanks for this response. Completely agree that we need to build things that give us quick-wins. Writing a quick script that does something convenient illuminates the joy of programming like no other.

My point was of a more general nature, for those of us who want to make a long-term career out of programming, and keep getting better at it. A lot of us (myself included) get stuck re-building simple stuff in a newfangled technology every few months and mistake that for progress. If we are to ever get to a place where we have the confidence to build larger and more complex things, we have to try making them, instead of being slaves to the latest project with the most Github stars. It won't be easy, but that is the point of deliberate practice - do something that is slightly beyond our reach and slowly push the bar.
Physics.

Really.
I like C#'s approach where a static function can be called as a method by adding the "this" keyword to the first parameter in its declaration. This makes it opt-in, which is annoying for legacy code. All collections got a fantastic map/filter/fold system bolted on through this mechanism, and as Bjarne noted the dot notation is great for chaining calls.

So in C#, to declare an fn as an "external method" you say:

static void MyFunc(this MyClass myObj, int someParam){doStuff();}

Which can be called as

var foo = new MyClass();
foo.MyFunc(5);

The downside is that method not found errors become much more complicated and it's not obvious to the user whether a method is coming from a different package or not.

Amorality in an economic system is a good thing. It means that participants impute their values within the institutional framework. An economic system actually designed to be "moral" (I can't think of anything other than Marxism-Leninism, everything else is hypothetical cost-the-limit-of-price, anti-usury, Social Credit and mutual aid arrangements) would be not only inflexible, but such a morality would necessarily emanate from a top-down institution that is immoral itself.

真有意思。I see a lot of dismissals of the projections in this article. Thirty years ago, just as I was working for several years as a Chinese-English interpreter, I would have agreed with all those dismissals. I no longer agree. As some of the subcomments here have pointed out, all that automated translation and interpretation have to do is become less expensive than either a) learning the relevant language yourself or b) hiring good-quality human translators and interpreters. Automated translation and interpretation is already well along that path.

A crucial skill for a professional interpreter or a casual language-learner is "lexicalization," figuring out what the correct match is between what is possibly a phrase in one language but only a single morpheme that is part of a larger word in another language. But the huge advantage automated translation solutions have is shared learning and long-lasting memory. If the lexicalization is built into a database, for example a database kept by Apple, Google, IBM, or some other multinational provider of translation services, that learned information can be deployed in products over and over and over again. In the end, that's all that it takes for automated translation and interpretation to do better at equal cost (or as well at less cost) compared to human language-learning or human language services. I got out of interpreting for a living years ago, because I finally came around to the understanding of how little I could compete with the worldwide efforts made with new technology to tackle language problems. I still think learning natural modern human languages is a very intellectually enriching activity, and all my children do that, but we expect to live in a world a decade from now with very good real-time interpreting and translation systems for a wide variety of language pairings.

> 20 years ago, an engagement ring was 1 solitaire diamond. Now, it's much more common to buy a ring with 1 big diamond, 2 smaller ones on the side, and small diamonds around the ring

My favorite article on the diamond business is this 1982 print from The Atlantic, "Have You Ever Tried to Sell A Diamond?" [1]. I excerpted two relevant passages below.

"The diamond market had to be further restructured in the mid-1960s to accomodate a surfeit of minute diamonds, which De Beers undertook to market for the Soviets. They had discovered diamond mines in Siberia, after intensive exploration, in the late 1950s: De Beers and its allies no longer controlled the diamond supply, and realized that open competition with the Soviets would inevitably lead, as Harry Oppenheimer gingerly put it, to 'price fluctuations,' which would weaken the carefully cultivated confidence of the public in the value of diamonds. Oppenheimer, assuming that neither party could afford risking the destruction of the diamond invention, offered the Soviets a straightforward deal -- 'a single channel' for controlling the world supply of diamonds. In accepting this arrangement, the Soviets became partners in the cartel, and co-protectors of the diamond invention.

Almost all of the Soviet diamonds were under half a carat in their uncut form, and there was no ready retail outlet for millions of such tiny diamonds. When it made its secret deal with the Soviet Union, De Beers had expected production from the Siberian mines to decrease gradually. Instead, production accelerated at an incredible pace, and De Beers was forced to reconsider its sales strategy. De Beers ordered N. W. Ayer to reverse one of its themes: women were no longer to be led to equate the status and emotional commitment to an engagement with the sheer size of the diamond. A 'strategy for small diamond sales' was outlined, stressing the 'importance of quality, color and cut' over size. Pictures of 'one quarter carat' rings would replace pictures of 'up to 2 carat' rings. Moreover, the advertising agency began in its international campaign to 'illustrate gems as small as one-tenth of a carat and give them the same emotional importance as larger stones.' The news releases also made clear that women should think of diamonds, regardless of size, as objects of perfection: a small diamond could be as perfect as a large diamond.

...

As American consumers became accustomed to the idea of buying smaller diamonds, they began to perceive larger diamonds as ostentatious. By the mid-1970s, the advertising campaign for smaller diamonds was beginning to seem too successful."

I'm not a fan of string theory, but I'll say that so far we have yet to find naked singularities which would be very easy to spot considering the various simulations that describe their traits. And it would be a horrible universe if such things exists with or without an event horizon considering what they could do to causality.
> I think most problems of that kind boil down to economic issues.

Probably, yes. But whatever "economic" reasons there are, the cultural reasons were probably much more powerful.

Maybe men were more scarce in the past than women. Wars might have accounted for that, but on the other hand, men have longer "expiration date" (when it comes to mating). Also, if men were so much rarer, why didn't polygamy develop?

You could claim that women are weaker, so they were less "useful" in the past (when most labor was manual) and hence less valuable. On the other hand, without a woman, there would be no next generation, so each man needed a woman to ensure his survival in old age.

These are the most obvious justifications I could come up with, and they don't sound very convincing. Let me know if you can think of any more.
I thought this was about how the entire world is getting to a point where they are able to speak and understand basic English.

There are certainly countries and population groups that do not speak English well, but it has changed significantly the last 10 years.
