I came across this article while researching whether Coleman lantern mantles are still radioactive. Putting a mantle close to this detector would be one way to find out. Traditionally, lantern mantles were made with Thorium to produce a brighter and whiter light.

It turns out that most current mantles (including those made by Coleman) have switched in the 1990's to using non-radioactive Ytterbium, although some claim that that the older Thorium mantles are both safe and more effective: http://www.colemancollectorsforum.com/post/peerless-mantles-...

If you are excited by this but don't have a good source of dry ice (and are electronically inclined) there is an interesting alternative design that uses Peltier coolers and a PC power supply instead: http://www.instructables.com/id/Make-a-Cloud-Chamber-using-P...

Also undersea cables have substantial benefits for long distances: Less chance of getting cut; fewer border issues to deal with; easier to route around conflict zones; the water acts as a natural boundary against simple opportunistic theft or sabotage. So even places where there may be a shorter land route you'll often find undersea cables.
Swarmbuddies: A Swarmbot Engineering Education Kit
Theoretical physics encompasses far more than speculative hypotheses with no experimental support (and in some cases without a way to even describe accurately any experiment which might lend support). A majority of theoretical physics (including some areas mistaken to be "purely theoretical") consists of work where there exists the means to experimentally support (or falsify) hypotheses right now, or at least construct experiments which could do so.

They tend to be less glamorous than string theory or loop quantum gravity, though, and so they don't get as much attention.

Few mistakes foursquare did with swarmapp
If you want update your nice project, please, do not do this:

1 - move users from one app to another twice to do regular actions (eg: checking and view infos about place);

2 - no new value against the older app;

3 - terrible call to action message: 'keep up and meet up with your friends' (I can do this with any other social network);

4 - less features/values than older app (checkins on new app doesn't count to mayorship);

5 - block user actions in my old app(terrible way to force users move foward);

6 - until nowadays not explain to users why the new app is better than old one;

... you are invited to put more and more here...
Also makes sense as does similar comment. Not convinced though, I should at least see it going on even if it wasn't happening to me.
Please don't pursue religious flamewars on HN.
I think what surprises me is the discrepancy between reading about mathematicians who worked with younger students out of seemingly altruistic motives (Kolmogorov and Erdos come to mind) and then a contemporary math department that might only accept 1% of applicants out of a pool of qualified people because of perhaps funding concerns or some interest in maintaining exclusivity. On top of that, there is a long history of mathematicians who worked on problems without any monetary compensation and perhaps without being associated with any university. Decartes and Fermat were both lawyers and even recently Yitang Zhang didn't seem to be paid to do research, and I don't count adjunct lecturer as a paid research job.

Given these, I don't see why an organization can't get together and simply agree to communicate, work together, somehow find a way to minimally provide access to journals for its members and dutifully train new students and grant them degrees. A Phd may or may not be optimal, perhaps something less stringent. A lot of people I know personally didn't get in to the field because they wanted to get rich, some sacrifice may be required but at least there is no denying a sort of "volunteerism" in mathematics.
How are you making that bet?
It just amazes me how most comments and even the project itself is based on the idea that in 10000 years civilization will be much inferior than current ones. I know you have to prepare for the worst case scenario, and that's how it must be planed, but still seems that our imagination runs wild.

Some comments talk about it, but I think the reason is missing. ANY kind of sign, text, symbol, phenomenon, structure, will only draw attention. No matter how dangerous it seems, people will be attracted to the mystery. The more dangerous it seems the more they'll get attracted to it. It´s about attention and the lack of it.

The best option is to make it seem like nothing it's there, no buildings, no signs, anything. Just bury it deep, restore the natural environment, create a natural park (restricted if you want while the memory stands) and if possible remove all economic incentives close to the park, so the population is reduced overtime, ideally till 0.

Another option I haven't seen mentioned could be to bury it in a geological subduction zone (at considerable deeps of course), so over time all the radiation gets dragged deep inside the earth by the tectonic movement. This would cover the 200000 years problem I guess. I don't know if there is such a zone that could be useful or safe enough for this, or if the geological tempo is fast enough to be of any use.

Edit: Iphone typos, and some editing for clarity.
Terrible, terrible idea. The hazard of Turing completeness is that once you have it you will have to keep it. And the mind-rending horror of programming in a DSL that accidentally achieved Turing completeness has to be experienced to be believed. Let alone the horror of having to maintain it.

It also invites hideous hackery at the wrong level of the system. It turns trying to read a mere system config into trying to read source code. You will write some hideous spaghetti code in the accidental language. And then your future self will curse you.

There is no way the proposal in this blog post is a good idea.
At work we are using rails-assets.org to include bower packages as ruby gems. rails-assets.org gets added as a source in the gemfile and run bundler as usual.

We looked at a couple of other integrations. rails-assets.org was the only one that did't require adding extra parts that need to get managed. Time spent managing multiple packaging systems is time not spent doing productive work.
Love it, Dave! I've been using webhook for about a week now and it's amazing how well you can integrate it with front-end tools. I've been doing some experiments building rich-media apps with content manageable through the webhook CMS. I know a ton of people who should be using this, especially since you can have a developer build a site and then hand it off to end users. Just what I would expect from the Giant Bomb guys!
An American may look at it that way. A European may look at it that way. Would an African? Would a South American?
The temptation to do this in proprietaryware is strong because then your customers can customise their stuff without you giving away your precioussss.

Of course, then you have to support the terrible, terrible programming language you have just invented by accidentally making your DSL Turing complete.

Examples: ant, MediaWiki parser functions, whatever that thing Varnish uses is ... the Varnish one is less terrible than most Turing-complete configuration languages, but it still turns trying to read a config into trying to read source code. You don't want to do that to your future self.

(I have had to write actual code in Ant. It's as if COBOL were written in XML. Unbelievably horrible.)
Why not?

A Russian scientist who was struck by a particle accelerator beam
I've seen permanent adjuncts / post-docs. There was a guy at my old school who was there as a post doc. He did his PhD at UC Berkeley. I can't believe that he has been jumping around to different institutions as a post doc or lecturer for over 10 years. It's quite sad. My friend did his Ph.D at University of Oregon. It took him 6 years to finish it. Then he spent 2 years as a post doc at University of Toronto. He finally got a job back home at a small 4 year college. I guess he's doing what he set out to do: be a university math professor. But, I believe him being from Hawaii helped him land that gig. They prefer locals who want to go back home before considering others.
Very nicely done - now I just need to pick up Ruby and find a good use for this gem :)
Yep! I came up with that one, at least /grin You start running into various complexity problems with further counter hacks of course :) but institutional investors as LPs with established, credentialed due diligence processes (e.g. CalPERS) may be a response there.

But these were all details to be worked out over the next few weeks iff the WH was willing to move forward with these discussions. It's unclear if that's the case, unfortunately. So we might be discussing details that were never on the table for a broad proposal that has already been rejected on the political merits.
You were downvoted, but I think this is an excellent question, especially about faddish products, and especially when they are a staple of LDCs.

It's easy for the spike in demand to have bad environmental consequences (e.g., biodiesel, Fiji water), or economic consequences for people who depend on the crop as a staple (e.g., quinoa). And this would certainly be a factor in whether I will buy the product.

But this doesn't seem to be the case (yet) with coconut water: http://www.motherjones.com/blue-marble/2010/07/coconut-water...

I visited Kerala several years ago, and I have to say the life of a coconut farmer there seemed to have its advantages. They spent their days tending their carefully cultivated trees just a couple hundred meters from a beautiful coastline.

The "labor supply" side isn't the only factor in downward pressure on the value of apps--it's also the quality of the demand side. People tend to the cheap side when it comes to paying for apps. The result is that each marginal increment of "value" in an app comes with a geometric increase in cost to produce it. It's also a feedback loop: people aren't willing to pay (very much) even for good apps because there are a sufficient number of developers doing it "just good enough" and giving it away for free, and so developers who could make an even better app shy away from doing so since the prospective benefit doesn't merit the risk.

I agree with you (that it could be an important tool).

However I will say that the VB6->VB.Net transpiler which Microsoft produced (and clearly spent significant amounts of effort on) was pretty terrible. And that is one of the most "complete" transpilers I know of...

The problem is that for a transpiler to produce "good" output code it needs to have a deep understanding of both context but also intent. This is particularly important when converting from one language to another with slightly different underlying concepts (like VB5-6 Vs. VB.Net). Without that understanding it just produces spaghetti code, that will technically compile (*although often it didn't in the VB6->VB.net example) but is unmaintable.

I liken it to Microsoft Word's HTML engine. Word can produce websites, and those websites technically looked correct in most browsers, but they became an unmaintainable mess in the medium to long term. A lot of transpilers have the same issue.

The best thing I can say about transpilers is that they're very good for a starting point (assume 100% refactoring anyway) and converting simplistic data storage vehicles (e.g. classes with tons of constants).
Worth pointing out that unlike some NoSQL engines, Aerospike does have access to its own query language (AQL) that is syntatically similar to SQL...
https://docs.aerospike.com/pages/viewpage.action?pageId=3807...

From the AQL query documentation you have...
SELECT name, age FROM users.profiles WHERE age BETWEEN 20 AND 29
...which is pretty easy to understand.

Yes to academia. Academia is hard to break into, and from what I gather from talking to a lot of math professors, it seems to have been this way since the 50's.

No on industry. I'm on other math forums, and judging by the constant reposts of "Finding a job with a math degree", I really believe that it's tough finding a job in private industry as well.

Personally, I decided not to do a pure maths degree but instead concentrate on statistics. The job prospects in industry are much better in that field. And, my goal was to teach at community colleges. From my discussion with CC faculty, their most popular math courses are statistics. So, they often look for people who have strong stats backgrounds. My plan is to find work as a statistician and work as an adjunct until I can land a permanent TT job at the community colleges. I just got certified as a SAS programmer, and there are lots of jobs at there I can do remotely.

the US government does check processing free of charge

Does it?

With passage of the Monetary Control Act of 1980, Congress required the Federal Reserve Banks to charge fees for payments services (including checks, automated clearinghouse transfers, wire transfers, coin and currency, settlement and safekeeping) that are priced to recover the Fed’s cost of providing those services (including direct and indirect costs, overhead, imputed taxes, and imputed returns to capital). The Act was designed to increase competition between the Fed and private sector service providers.

No, I'm actually starting grad school next month. But, I decided against a PhD and will just do a masters in math with a concentration in statistics. My ultimate goal was to teach at the community colleges anyways. I really don't want to do research for the rest of my life.
Overhead, I'm on a fast-track 3yr EU PhD admittedly the US system is a different animal in this regard. Is it the only way to become an expert, of course not and I don't think anyone is making that argument.

Yes I did read the article. So you're equating "job prospects" with "chance of being a tenured professor in a specific field", more usually it means the opportunity to enter a well-paying or otherwise respectable career of any type.

Costs, sure I imagine I would earn more as a technician in industry with an MSc but if you're driven by immediate-term financial gain I'd agree a PhD is not for you.

Prestige, at PhD level it matters less about the institution than your specific advisor. Also I'd argue science is ahead of most careers in being a meritocracy, the quality of your publications should count for more than your institute's ranking. Should people care about the level of research of their institute as judged by an independent group of peers, probably yes.

The core code is written in C, but they're definitely using Lua in places, I believe they've incorporated some code from AlchemyDB... https://code.google.com/p/alchemydatabase/

From what I've read it could easily surpass Mongo, just look at the cost savings...

"The second comparison (a video ad serving platform) had much bigger requirements, including a 5TB database processing 500,000 TPS. The hybrid SSD-DRAM setup running the AeroSpike database was able to handle the load with just 14 servers, at a total cost of $322,000, compared to 186 servers using NoSQL running on clusters of servers that use a lot of DRAM and cost $5.6 million."

They´re ACID compliant as well, which Mongo is not (AFAIK)...

I'm pretty sure the owner cares about profitability.
The first half of their existence was spent as an unprofitable business. If 2014 ends up the way it looks like it will, the net losses will outweigh the net income for the life of the business (it nearly does now).

The first ten years of their operating life were spent being famous for bleeding prodigious amounts of red ink. That's why the tag: Amazon.toast - it was assumed they would bleed to death without the easy money of the public market and a massive valuation.

Here's their net income statement going back to '97:

1997: -$32m; 1998: -$124m; 1999: -$719m; 2000: -$1.4b; 2001: -$567m; 2002: -$149m; 2003: $35m; 2004: $588m; 2005: $359m; 2006: $190m; 2007: $476m; 2008: $645m; 2009: $902m; 2010: $1.15b; 2011: $631m; 2012: -$39m; 2013: $274m

They've never been quite profitable. Only one year, 2004, did they show even a modest level of profitability (in part due to one-time gains). The rest of the positive years the margin was between 1% and 4% typically.
That was an interesting thought. I had to look at the numbers a bit. In Sweden in 2012 69,216 companies where created [1]. In all of 2012 7,471 companies were declared bankrupt [2], about 10%. If 85% fail, then another 75% should have shut down voluntarily. That is out of 1.1 million companies of which 888,000 had some turnover last year [3], Can't find the statistics for the year on year growth though right now.

Edit: found the stats. Seems the number of companies have only grown by 10% in total or so in six years [4]. So maybe you are right then.

It's a bit interesting, as it requests a bunch of Russian IT companies to stop their ongoing projects with another bunch (the sanction list) of Russian companies.

It would be obvious that USA companies (and their Russian subsidiaries, if there are any) are limited by the sanctions; however I'm not really seeing what power USA or RedHat should have to restrict those Russian-to-Russian support contracts.

Ask HN: Do I really need an incubator/accelerator?
There are some accelerators and incubators that are advertised around Vancouver, BC. I was filling out an application form for GrowLabs but stopped just shy of submitting it because I hadn't fully answered the question, "is this really necessary?". I filled out the form half heart because I felt like I was just doing this because "everyone else was doing it".

I've spent the last 8 months or so building an MVP for http://scrape.ly. Bootstrapped and getting ready to launch very soon.

What are some reasons for joining such incubators or accelerator programs? Is real value provided for giving away 10% of your equity?

My original plan was to get to about 20 or so customers, get a small shared office.

Your experiences of joining such accelerators or other stories would be interesting.
