I think you may plateau quickly with 100 words per day and I think that plateau is well below 20,000 words.

Memorizing a foreign language word is not just translation, it's about understanding context and usage for that word.

When you tread outside the "trivial vocabulary kit" you lose bijection between languages and acquiring words becomes harder and harder.

Keep in mind I have nothing but my personal experience to back that up, which means formal studies on the topic are more than welcome to enrich the conversation.

§66 on page 20 of Directive 2009/136/EC at [1] uses the word "information", not "cookies".

Third parties may wish to store information on the
equip­ment of a user, or gain access to information
already stored, for a number of purposes, ranging
from the legiti­mate (such as certain types of
cookies) to those involving unwarranted intrusion
into the private sphere (such as spy­ware or
viruses). It is therefore of paramount importance
that users be provided with clear and comprehensive
infor­mation when engaging in any activity which
could result in such storage or gaining of access.

The purpose of the directive is to be as broad as possible to cover collection of any type of information without express permission or "strictly necessary and legitimate purpose".

Sounds like an opening for an App.

Gabriel's put a lot of effort into creating his flashcards, but they'd be the same for everyone - so you could allow the community to generate the cards, and the part of the community for whom this is their native language could rate these cards, the best bubbling to preference.

The use of existing sites (Google Translate / Lang-8) to get/validate translations is good, but this could be baked into the same system as the flashcards, using that system's community, or having an API to connect that system with the external sites so that it's just one system from the user's perspective.

In terms of reading books / watching tv / etc, again a catalogue of links to e-books / youtube clips / etc., along with ratings of difficulty could be maintained by the community and presented through the app.

Build this on top of facebook / google plus / etc and tools such as hangouts are also available to help users from different countries / of different native languages talk to one another, taking it in turns of 30 min sessions in one another's languages.

I think what you have is a handful of 800 pound gorillas who have successfully figured out how to monetise information hoovering up start ups for talent and information that they can plug into their own platforms & monetise. Everything else is perhaps feeding off that, so my bet would be, this all stops when someone ends up buying twitter, that might well be google, at that point everyone will be busy integrating all their new data into their existing products and attempting to monetise it.

My 2cents anyway.
I find it elegant. It's like Javascript with the warts removed.

As having gone to engineering school, I agree with you.

But the main issue is that most technical courses are given by people with a strong foothold in academia (and a lack of knowledge of "the outside world")

Good teachers go a long way, you have to be aware of the issues to realize they're happening once in the "real world".

You have to know the technical aspecsts, but if you restrict yourself to that, you'll spend your life in Dilbert's world unable to change things. And when it's your turn to lead, you'll do exactly the same as your boss did.

This list is very important, and the most amazing thing is how many people don't know 10% of it, even in companies!
10 Smart Risks That Every Business Should Seek Out
That already is regulated in the EU, which has reasonable data protection legislation.

This is just supposed to be like the signs you are required to have if you use cctv, letting people avoid it if they wish to.
You make a great point: Mobile carriers could differentiate themselves from other wireless providers (such as Clearwire in the US) or from each other, by accelerating VOIP traffic instead of degrading it. HTTP degradation could automatically adjust on an overloaded node to make room for VOIP.
The only reason keeping one country from launching nuclear weapons at another one is Mutual Assured Destruction principle. Without nuclear weapons, the world would be a much more dangerous place to live.

We had two world wars in the first half of previous century. It was a like a loop: as soon as new generation of youth eligible for combatant service grew up, world war started again.

Fortunately, nuclear weaponry ended that loop, and Mutual Assured Destruction principle is the only reason for protracted peace at the global scale.
Google did not just implement the language. In fact, they didn't implement the language at all: to the best of my knowledge they haven't even written a Java compiler.

All they did was write a translation tool that takes Java binaries and makes them run on a different VM, not covered by the Java license. Unlike others who implement languages to provide technical benefits, Google had no such intention. Their only consideration when choosing to re-implement a piece of Java or not was whether it would allow them to evade Java's legal restrictions.

My stake in this is that as a Java/other-JVM-languages developer, I don't like the fact that we now have two incompatible Javas. Now, Google explain their actions by saying that Sun were dragging their feet during negotiations, and maybe they're right. Maybe, thanks to Google we have an almost-Java thingy on a successful mobile platform.

I think the parties should settle, and I hope the result (whether money changes hands or not) would be bringing Android in the Java fold, and making it compatible.
they already released a fix for it, yesterday.
The IBM videos about this project are much more careful than the breathless article from extremetech.
for the comments: that's a matter of taste, IMHO.

for bitwise ops: look at 5.2, it has it now. 32-bit operations.

floating point arithmetic: in practice, I haven't seen it as a problem as soon as I stay within the 32-bit range - then the numbers can be represented exactly, so the abstraction works well.

OOP: can't say for it, I did not do it much.

For the "fast" - check luajit (http://luajit.org/) - it is near-native speed while remaining reasonably slow.

And the FFI in luajit is simply fantastic. Take a look at https://github.com/justincormack/ljsyscall which binds the syscalls.

The annoyance that I'd thought of is that the array indexing starts with one, not zero - this brings some headaches during the index calculations. But this also forces to rethink the logic to use more of iterators, and abstract away from the indices. So, after all, it is not that big of a deal.

If every country had nuclear weapons, would there be no more wars then? And to take it one step further, if every man had a gun, would there be no more murder?

It's fair to be skeptical of all these announcements but I can't help but think that batteries have gotten better over the last 15 years. Whether these improvements were "breakthroughs" or not is a matter of interpretation.
How?

I've heard this argument many times but can't actually think of any non-idealogical reasons why it would.
There have been quite a few battery breakthroughs at the lab level, especially in the past 3 or 4 years. That is massively different from scaling up manufacture and bringing to market.

Also, I suspect that investors in this sector are hedging their bets and waiting for a clear winner to emerge before spending the big money.
This was an option, and it seems the uk wanted do not track or browser settings to change in time for this but it didnt happen. If it does the guidelines will change.
The site focuses on the UK implementation of the law, but unfortunately the directive is EU wide and individual member states are hence supposed to put it into law, too. I say supposed because as in typical EU style, the member states are lagging, or doing their own thing.

http://www.dlapiper.com/files/Uploads/Documents/DLA_Piper%20...

Who are screwed: Austria, Latvia, Lithuania, Sweden and the UK.

The actual law says that any non-strictly-needed cookie (or whatever you use to track users) MUST receive PRIOR opt-in from the user. It also clarifies that non-strictly-needed must be read in the narrowest sense possible, so that even saving user preferences is considered non-essential. As far as I can tell this means that even normal use of session cookies is outlawed.

There seem to be some posters here who think the law only matters for analytics, and hence as users it's not their problem. You couldn't be more wrong, there is no such restriction in the law! This will effectively make the internet unusable unless websites start grouping login/cookie access. Like with Google/Facebook/Twitter account login systems. If the intent of the law was to hamper those companies, it will effectively achieve the opposite by hurting the smaller players disproportionally.

And of course, you might not have to care because this will likely end up mostly unenforced. But as a site operator, it's still a Damocles' Sword hanging above your head if you ever get Kafka'ed. The fines are not small.
Tim Berners-Lee: we don't need arbitrary new TLDs
Exactly. 10 years is way past the Technological Event Horizon, which is about 2 years.

Which means that unlike, for example, memristors, lithium air batteries most likely won't happen, and if they do happen, their happening will be a consequence of other research.

(Which is an argument why most research should be fundamental and open-ended, i.e. not directed towards specific outcomes.)
They invented NiMh batteries that hold their charge for a while; now I can actually use them in game controllers and flashlights and such without needing freshly charged ones every time I've left 'em in the closet for a few weeks.

Not a density breakthrough, but a UX breakthrough for sure.

Wouldn't that mean that the device will first try to download all of the low res images and when the script finished loading and is running, the device would then start to load all of the high res images. How's the user experience with all of those additional requests and traffic? (especially via GSM/CDMA)
I restarted blogging as well recently, and found the same thing. I've got a couple of under-documented JavaScript topics that I appear to be blogging about (one just under-documented, one brand new). Only catch is, I don't really know Javascript. I mean, I know it in the "sure I can make that thing bounce around your screen" way, but I've never worked with it on the server side, ever.

Blogging about my progress has reinforced how little I knew. In going to explain a topic, then suddenly realizing I didn't know how to explain it, I just knew how it was supposed to work. This has put a spotlight on what I didn't know, and I find great value in it.

The other upside is that people apparently think I'm kidding when I say "I'm just learning this" in my blog, because I routinely get questions via IRC of a much more advanced nature from people trying to extend what I've taught. I like to help, so I always give it a shot, and usually that means diving into source and learning more -- win/win.

Of course, sometimes I'll go answer a question on something I thought I knew really well, only to find out that I don't. I found out the other day that I don't really know how Django's form binding works. Somebody pointed that out, and now I do.

A sub-topic about this could also be that "Discussing something is the second-best way to learn something." I've never been one of those guys who hung out in chat rooms all day, but honestly, I didn't know what I was missing. Lurk around in #python for a day and I almost guarantee you'll see something you didn't know.
I see, thank you. None of this sounds like a show-stopper to me, but it's good to have a more complete view of a language I'm not intimately familiar with.

You can already get this behavior in your browser by changing user settings. Just try to surf like that for a while. It's horrendous, and what's worse, it doesn't make the user any wiser, really.

We went through all this in Sweden a while ago, based on the same EU-directive. What has happened since the law passed here?

Not much. A few government-related sites have started showing an explanation about what a cookie is and does, and gives the choice of accepting or declining the cookie.

Other sites, despite the law, continues to function like normal. It's simply unenforceable on a large scale.

The user experience when viewing webpages is improved by actually showing a lower-resolution image while the crisp high-resolution image is being downloaded (however slowly), similar to progressive JPEGs.

Depending on the data contract, the user experience when viewing their mobile phone bills might be affected negatively though.
This showed a few things that weren't revealed in that recent Ars Technica article. Nice, James.
Indeed it would. Certainly less than ideal, but this provides an avenue to easily implement higher DPI graphics. Right now, it seems like the easiest method to get a site upgraded without having to make a ton of changes.

Ideally, we'd have something that would deliver only the correct image to the correct device, the first time. I haven't seen a clean method for achieving that yet.
Good point. Part of the reason really is that I couldn't find any Brazilian TV shows that I liked (Movies are better). And second, this phase is really for vocab and not pronunciation, so when I hear a English sentence and read its translation in the subtitles, I tend to remember the structure and some of the words. It just works for me.
Who's else is making high-DPI displays? I have really seen companies running with this. It would be nice to see Samsung, for example, start promoting 300 dpi screens so they go mass market.
Excepting crashing bugs development depends a bit on when people have time or a need for a new feature but Fluxus is indeed still actively developed. As I see it it's indeed "done" in the sense of being useful for it's intended purpose right now, but there is space for big improvements like redoing the editor itself in Scheme, morefunctionality in the Windows version, etc. I'm personally working on and off on a little library for new ways of interacting with generative music in it. We're alive and well, I'd say.

There's still a risk. Assuming you have done a good job of keeping your personal information away from "JohnnyFlash", no one will find your company through your posts here.

However, what about the other direction? Suppose your company comes to their attention through some other means, and they start investigating. At some point, you could find yourself answering questions under oath. It's conceivable the questioner might go on a fishing expedition, and ask "Have you ever posted on HN under the alias Johnny Flash?" (he might ask that at every company he investigates).

Then you've got the annoying choice between telling the truth and making your company's case for accidental violation much worse, or lying under oath which, if that is discovered, could bring serious penalties.
So ... As the battery is used, bonds are formed between oxygen molecules in the air, and the lithium ions on the battery's electrodes. Weight is saved by "borrowing" those O2s from the air, as compared to carrying them around fixed in an oxide. Fine.

Does that mean that as the battery charge is depleted (=it runs out of free lithium ions, I guess), it's mass increases due to all the newly bound oxygen being stored in there? That's counter-intuitive enough to just be awesome!

Also, a large-scale battery whose charge level is directly related to its mass (albeit inversely so, from my intuition) and supports recharging is almost a bit like magic. I hope they pull this off, so I can learn to weigh my car before going on long trips, in the future. :)
They are paying attention, one of the companies I deal with used to manage a lot of other companies, and their main website was listed for all these other companies.

Sure, but in a lot of today's apps there are no performance critical parts. They're already well under the ceiling of what the hardware can do all the time or they spent 95% of their CPU in optimized routines in the OS/kernel. Of course, a more expressive but faster language like Mirah or Kotlin or Go something would be ideal here.

The problem with writing glue code in a scripting language is that it doesn't really buy you much unless you can impose a new, higher-level abstraction on the existing UI. As these examples show, you haven't really improved on Cocoa if all you've done is changed the function calling syntax.
This is a very clever piece of blatant advertising. I think I'll buy some.

Sony's Xperia S have 338 PPI which is even more dense than Apples "retina display". So there are other companies using high dpi displays. Galaxy Nexus is at 316 PPI if I remember it correctly.

What if that information details acts of war by nation 2 against nation 1, however those acts have been, up until the publication of the documents, untracebale or unatributable to nation 2. For example Mossad paying revolutionary groups to kill off Iranian scientists, the release fo the documents would lead to condemnation of Mossad and stilfe their activities, thus saving some innocent scientists from being assasinated, sure Iran may want to retaliate but the other option is you allow Mossad to go on killing iranians (or anyone else they choose to) without bringing scrutiny on their actions.

Your example was extreme but it was poorly thought out. If the information is powerful enough to cause a nation to want to launch a nuclear weapon at another country then that sort of information needs to be publicised, whatever the hell it is that is bad enough to start a nuclear war is certainly not going to get any better by hiding it away from people.
