At the universal scale, we can observer several galaxies in various stages of colliding with each other (1). In fact our galaxy and Andromeda are on course to collide with each other in about 4 billion years (2).

Massive stars end their lifecycle in a supernova explosion, which blasts much of their mass off into space. the remaining stellar core either forms a neutron star or a black hole. The mass that is blated off contains many heavy elements formed in the star by nuclear fusion, and contributes to nebula formation. These nebulas coalesce to form new stars and their associated planetary systems. We can actualy see this happening in various places throughout our galaxy, with nebulas in various stages of coalescing and with multiple stars forming within them. Absorbtion spectra tell us about the materials these nebulae are composed of.

There is some speculation that heavy elements such as iron are also produced and scattered about in nutron star collisions.

Ask HN: How do I promote a newly launched, innovative, Wordpress plugin?
Hi HN!

We recently launched the Wordpress plugin for Bablic.com which allows you to localize/translate Wordpress sites in a much more effective and user-friendly way than what's currently out there.

I'm wondering if the community here has any good tips in terms of how to promote it?

Thanks in advance!

Why indeed? They're almost as bad as the drug laws. It's not whether folks are high or carrying weapons which matters, or should be illegal; it's what they do while high or with those weapons which matters.

That would rally hurt small publishers. For example, American Express is more or less willing to buy ads that appear pretty much anywhere so long as the the viewers have a certain income level. Absent an ad network, would ever publisher have to work with AmEx individually to try to convince them they have an appropriate audience?

The industry's dirty little secret is that for all the hand wringing about tracking and targeting, the tech is still really in its infancy and doesn't work very well.

Network ads already don't pay very much (IMHO) and removing the ability to build profiles on demographics would make them worth much less.

You're right that it's not a dealbreaker -- my startup would be OK since we ads direct to clients -- but mostly people aren't in a position to do that. It takes a team of ad sales and support staff, and a very particular kind of niche content.

Did anybody else read through the (English language) conference website for the (presumably English language) conference, and wonder to themselves, "Why ... Poland?"

I'm not knocking Poland, but it seems strange to have an English-language conference there and not offer anything in the way of explanation for the choice.

I mean, I'm sure there is a reasonable explanation (central location, picturesque setting, low costs, fits the ethos of a polyglot conference, offers the possibility of both a conference and a vacation) but I find it strange that the explanation isn't more visible.

As someone who uses both (vim and IntelliJ):

install boat-load of addons to try and replicate the IDEs they're decrying

The attraction is that vim is usually far more customizable and supports modeful editing (yes, there is IdeaVim, but it is quite a leaky abstraction). However, customizability comes with a price: it takes a while to set up.

The same holds for other applications. E.g. Mail.app is user-friendly, but there is little you can change in terms of shortcuts, behavior, etc. OTOH mutt takes a lot more time to set up, but you do nearly anything you want (including setting up GMail shortcuts and behavior).

3) still somehow recommend it even though it appears to be less efficient in the use case provided

That's why I also use IDEs. E.g. Go is really well-supported in vim, with completion, refactoring, etc. For Java, OTOH, vim cannot even come close to IntelliJ and others. So, I use an IDE.

The Techcrunch piece links to the original article[1], which provides more information. Rep. Steve Israel is a gun control crusader from way back, as is the Connecticut delegation and a few others. But the ban he proposes, obviously, won't stop anyone from printing a weapon and smuggling it onto a flight; it's just more so-called security theater, intended to assuage the anti-gun segment of the electorate and reassure air travelers that they are still going to be safe.

In my opinion, the only true way to ensure air security is to arm the pilots and plant more armed Air Marshals on flights.

Banning particular types of objects from being 3-D printed seems like an exercise in futility at best, and instills a false sense of security at worst.

Couldn't it be done in the age-old tradition of UNIX/Linux GUI frontends to command line apps? It seems like your installer (or the GUI app itself, on first run) could do all the work of downloading the Tarsnap source, compiling it and then simply launch the CLI program to execute the actions.

It'd take some dev work to set it all up, but could be transparent for the user.

Short version: computer scientists have shown that if the Edit Distance problem can be solved in sub-quadratic time, then SAT can be solved in sub-exponential time, and therefore P=NP.
I'd like to implement the same paper. Perhaps I'm missing something, but I'm not sure how the residual strings are created. Do you have a link to an implementation or a description of the residual strings?

I get that a residual string is the original string with a deletion, incrementing the deletions until you hit edit distance d. What I'm not sure about is if it's all permutations of possible deletions.

If you read the forum threads on performance issues, what they generally come down to is type-hints & using Java types.
The problem is that idiomatic clojure doesn't perform well (it may scale well but you throw away a bucket-load of performance by using it anyway).
The way to get truly good performing Clojure is to write Java...

Pixie does look promising and is more my type of thing (coming from a low-level background) but I haven't managed to have time to look at it properly yet tho.
I read "self-help" book a while back called "Stress for Success". The premise was that we can condition ourselves to psychological stressors in much the same way that a physically fit person can condition themselves to physical demands.

I agree with this. A certain amount of stress is good if you can overcome it and it makes you more resistant to higher stress in the future.
I agree that macros can hide the gray wall of machinery, but initially, even more descriptive terms can be confusing and unexpected. A longer-term win, but the initial burden goes up.

> I'd love Apple to get so big and monopolistic they could curate the Internet

So basically just for your own comfort you'd like a big company to become monopolistic and force its views on the web? I am not found of ads myself, but I think they are a better alternative to what you describe.
Some really dumb points in that article. Of course Apple has to provide access to a search engine in Safari - and pretty much all search engines run from ads. It neglects to mention that they recently added the option of DuckDuckGo. And of course Apple collects information on you to help improve its products - nearly every company in existence does this.

The difference in the two approaches (Apple/Google) is HOW it uses the data and the amount of data it collects/has access to.

>> "Mr. Cook also failed to fairly explore the substantial benefits that free, ad-supported services have brought to consumers worldwide."

Of course he didn't explore it - he'd be an idiot to explain to everyone the benefits of the very thing he was trying to say wasn't good.

>> "If Apple really didn’t think that its customers should trade their data for free services, you’d guess that it would build its own ad-free web search engine for its devices."

No you wouldn't. A search engine is difficult to build, expensive to build, and hard to do right. Instead they offer users Google as default (which the majority of people would want) and a more private alternative in DDG.

I could continue going through the article explaining how it is utter rubbish but it should be pretty obvious.
Wow, following this link[1] on their website, some of those examples are pretty impressive stuff.

Why Angular 2 will rock
> But it also means that computer scientists can stop agonizing about whether they can do better.

This is incorrect... because a "better" algorithm might have 99.9% accuracy but be millions of times faster.
Rising interest rates make it unattractive to hold long-term bonds. For example, when interest rates jump from 3% to 4%, the net present value of 10-year bond drops by 10%. So as soon as investors believe that the turning point has come, the rational reaction is to sell bonds, amplifying the raise in interest rates even more.

But where will they put that money instead? Letting it sit around in cash is not a wise idea because oftentimes, rising interest rates come hand in hand with inflation. Your best bet is to buy something of "real" value, be it gold, real estate, or stocks. In my opinion, this could explain the growing divergence between stocks and bonds. At least for a while, I would expect this to continue and stocks to go up with bonds falling, or at least stocks not fall as much as bonds.

Then again, it is very hard to predict such things.
Timelog – The most dead simple and responsive time-tracking platform
There have been a few attempts at GUIs over the years. I'm hoping that this one will turn out well; I think it's already more functional than any of the others, and it's being actively developed.
As I understand it, something like the big bang produces mostly light elements -- hydrogen and helium. Everything else is produced in the stellar fusion machine plus supernovas.

So, by the time that the heavier elements are forming, the big bang has been done with and forgotten about for at least, like a microsecond. ;-)
The German BSI is not part of the "intelligence community" and is not an intelligence agency, no matter how often you repeat your conspiracy theory. To spare everyone the trip to Wikipedia:

"The Federal Office for Information Security (German: Bundesamt für Sicherheit in der Informationstechnik, abbreviated as BSI) is the German Upper-level Federal agency in charge of managing computer and communication security for the German government. Its areas of expertise and responsibility include the security of computer applications, critical infrastructure protection, Internet security, cryptography, counter eavesdropping, certification of security products and the accreditation of security test laboratories."

Bitcoin Survey: Anonymity in Bitcoin
Dick Lipton (GATech) has a blog post discussing this paper: https://rjlipton.wordpress.com/2015/06/01/puzzling-evidence/.
I'm not denying that - the whole process is good stuff.

But I'm suggesting that "assembled in 19 days" is more accurate than "built in 19 days".
Here's the paper: http://arxiv.org/abs/1412.0348
It seems we have different definitions of "excellent".

Google Maps is certainly widespread, but it's hardly the only on-line mapping service available. They keep messing around with the UI, often not for the better. I often find the data itself and the live route planning/traffic news to be inaccurate.

Maybe it's better for those in the US, but here in the UK it's exactly what I meant by unremarkable. The local data from OpenStreetMap seems to be just as good for general mapping purposes and sometimes more accurate and/or current, and for car journey planning and real-time traffic news the dedicated satnav devices still seem to do a far better job.
That already explains a lot, thank you very much! I've read so many different definitions of time in physics - that was very confusing.

What your grandpa contends is exactly what I thought, too. I love the simplicity of that thought. But after reading about the relativity of time, I noticed that something must be missing. That's why I tried to imagine that space expansion I mentioned. In the end, it doesn't really make sense, but again the simplicity and thus the ease of imagining it is beautiful.
