But is the frequency of the signals prime numbers?


I always thought an interesting experiment would be to fire off a handful of nuclear bombs in space. (Rather deep space, like well out of where they could do any harm to Earth.)

Then pace the time between detonations to different prime numbers...


This is a core point in the Three Body Problem series of books by Liu Cixin (plus a little hand waving sciency signal amplification). As mentioned below it turns out to be a generally bad idea


I just discovered this trilogy and have just finished the first book. Truly what a great story


The second and third book are even better :) You're in for an amazing ride! Enjoy!


I disagree; I would stop at the second book. Death's End reads like Stephen Baxter/Greg Egan fan-fiction.


> Then pace the time between detonations to different prime numbers...

There is a problem though. Whose time ? Your time, observers time ? Are the bombs moving with the same velocity ?

> Are the bombs moving with the same velocity?

Relative to the speed of light, where these effects actually become appreciable?

Yes. Hell yes. Basically identical velocities. Signal to noise ratio issues will do in this idea long before relativity has any sort of impact; it's not even close.


Won't the ratios should remain the same? A change of inertial reference frame in SR is just a linear transformation.


That may not be a good way to announce peaceful intentions to the galaxy. But anyway, they would probably be too faint to detect by anyone.


Too faint? Is there something about the Drake equation you would like to share with the rest of us?


The Tsar Bomba test produced 5.3 yottawatts (about 1% of the power output of the sun) but only lasted 39 nanoseconds.

I wonder if that would be noticeable over interstellar distances?


1% of the Sun's output power seems really huge. Is this accurate? Any references?


According to this:

https://wattsupwiththat.com/2006/12/08/yottawatts/

Tsar Bomba - 5.3 YW

Sun - 386 YW

39 nanoseconds isn't very long (~39 light-feet).


~12 light-meters for our non-metrically challenge friends.


I was using feet to emphasise I was being silly ;-)


Not really that deep at all, it turns out you can fire off nuclear bombs above about 80km up and they are essentially harmless to life, causing only electrical (i.e. EMP) effects.


Way to miss my point


Why exactly would you want to draw attention to us?


To show that we're bad-ass


IMO they already know. That's why they're waiting for us to evolve one more thousand years before contacting us.


Wouldnt 'they' have evolved 1000 yrs as well? By that time their own current state of evolution would look even less developed given the exponentiality of evolution.


Perhaps we just need to stop being dangerous to other species and ourselves. Embracing the pursuit of collective goals would be a huge advance in our civilization level. Beyond that point athough less developed we could be accepted for not being harmful anymore.


no.. you're assuming that other species develop technology at a similar rate, and that our current progress will continue at the same rate. Both are things we don't know.

There may be hard limits that stop development of technology past a certain point. Like Moore's law coming to an end, but one day we may not have any viable alternatives.


…not if they're moving faster.


Or waiting for us to evolve enough to provide good sport.


Nah, they're fattening us up to be the intergalactic version of Wagyu.


Or waiting for us to compute 42


I said it would be interesting, not that it would be wise. :-)

Curiosity killed cat.

Is CoffeeScript still the default then? I see it referenced in the codebase still.


I'd imagine with ES6 all nicely wired up in this release that moving away from Coffee would be an obvious next step but was way to large to undertake in one release.


CoffeeScript was never the "default". Since the asset pipeline was added new rails projects contained only a single 'application.js' which included any default JS libs. There has never been coffeescript in a default rails project. That makes the default plain-old JavaScript. CoffeeScript has just been there as a default gem so it was available to you by default, but you have never been forced or even strongly encouraged to use it.

That said, I love CoffeeScript and continue to use it to this day. It gets a lot of hate and I've been pushed to write a lot of ES6 these days, but CoffeeScript is still much more succinct.


I was a happy Postman user for a long time. I tried Paw on a lark (the importance of free trials) and loved it. Totally worth the money to me, and I've only scratched the surface with it. I especially like the plugins ecosystem.


Yup. To riff a little bit on those bullet points: If the interviewer[s] is displaying that behavior during an interview, expect the entire company to have exhibit the same stuff, only by an order of magnitude more.

If the interviewer doesn't respect you, then management doesn't respect or listen to employees.

If you only get canned questions, then the company cares more about checking boxes than creative thinking.

If the interview process is complicated, _everything_ is complicated.

If they aren't paying attention, then nobody pays attention in any meeting, so they get repeated, or stuff constantly falls through the cracks.


Seems like it's hitting primarily iPhone 6 users. https://twitter.com/jsnell/status/514830848374214656


From what I've gathered, the only thing Gruber is upset about is the name "Standard" Markdown. I don't think he cares if there is some kind of body that has some kind of standards thing. I'd bet that if the "Standard Markdown" people called it something else and even kept the exact same syntax, he'd be fine with it.


I believe it was the 2 parter with Marco Arment. Either this one: https://daringfireball.net/thetalkshow/2014/07/19/ep-088 or this: https://daringfireball.net/thetalkshow/2014/07/19/ep-089

Just several hours to sift through :)


Holy moly. That's almost like the one Far Side cartoon with a "Wings Stay On" "Wings Fall Off" switch. http://imgur.com/AosYvGn


Yeah, he found that out after posting that blog. https://twitter.com/chockenberry/status/474704755348881408


It's there, where I mention that I've been following them since their inception. Yataa is also linked to it.
