“Erroneous wave functions of Ciuchi et al. for collective modes in neutron production on metallic hydride
cathodes”
A. Widom, Y. Srivastava, and L Larsen (v1 Oct. 17, 2012)
http://arxiv.org/pdf/1210.5212v1.pdf

Abstract: “There is a recent comment [1] concerning the theory of collective many body eﬀects on the neutron production rates in a chemical battery cathode. Ciuchi et al. employ an inverse beta decay expression that contains a two body amplitude. Only one electron and one proton may exist in the Ciuchi et al. model initial state wave function. A ﬂaw in their reasoning is that one cannot in reality describe collective many body correlations with only a two particle wave function. One needs very many particles to describe collective eﬀects. In the model wave functions of Ciuchi et al. there are no metallic hydrides, there are no cathodes and there are no chemical batteries. Employing a wave function with only one electron and one proton is inadequate for describing collective metallic hydride surface quantum plasma physics in cathodes accurately.”

Conclusions: “No signiﬁcant argument has been provided against our nuclear physics results. The experimental evidence of neutron production and nuclear transmutations in properly designed plasma discharge electrolytic cells [5] agrees with our theoretical analysis and belies the theoretical arguments given in [1] against a hefty production of neutrons in hydride cells.”

Indeed, looking at capital costs for our product the injection mold tooling is one of the most expensive aspects of production. Rapid prototyping (CNC milling/laser cutting/3D printing/etc.) reduces the cost of iterative development, but there's no way around what it costs to ramp up for production.
Correct. A developer with a full brain would know better than to extrapolate a few examples to an entire industry.
jquery and bootstrap are great for putting together a rails app really quick, but I wish there was a better way that didn't add bloat. I find that jquery and bootstrap add significant download latency to a webpage even if they are gzipped.
The difference between $329 and $299 is $30, not $20.
Better: buy a subsidized unit but don't buy their DRM ebooks ;) It's trivial to do.

The sale of one iPad makes up for a LOT of lost sales in the app store. I'm sure it doesn't bother them yet.
>The more productive you are, the more likely you are to get down on yourself and think at the end of the day, “I wasn’t very productive today.”

Wow, that sounds like an incredibly unjustified relationship, with only the superficial support of its counter-intuitive nature. In my experience, the opposite happens, the more you do in a day, the more you recognize and remember that you accomplished that day, and consequentially, feel that you accomplished. Which by the way, is exactly what the anti-todo list is, except with a mental list of remembered accomplishments, rather than manually recorded ones. The latter act should only be necessary if an individual has a particular problem recognizing what they've accomplished in a day; I don't think this is some deep insight or universal principle.

Android lets you measure in device independent pixels, though (i.e., ppi doesn't matter) and automatically resizing layouts (something that arrived in iOS 6, I believe). So it's not as bad as all that.
You mean RFCs :)
Isn't the downside of FEC encoded packets increased latency? Instead of sending each packet immediately, don't you need to accumulate n packets to encode as a group? Or does the math allow incremental encoding? Simple parity is incremental, but the FEC on DSL lines always added 40ms of latency.
Theoretically, that doesn't simplify the problem at all. Practically, we can say that Mass_probe=0, in which case we have a 2-body problem. We need to do that even if we do find a closed form solution to the n-body problem (which might be provably impossible), becuase in reality there is an infinite number of bodys in the system.
I so want Phil Schiller to take over all Keynotes. He is very clearly the best presenter Apple currently has. I don’t think an Apple CEO has to be a good presenter. Just because Steve Jobs could fill that role doesn’t mean Tim Cook has to force himself to do it, too.

I honestly was relieved whenever Phil Schiller came onto stage today.
But you do get the benefit of using arbitrary "point" conversions, i.e. $10 buys 8 coins, $20 buys 18 coins, etc. It makes it harder for the user to estimate the real value when purchasing, and thus easier to overspend.
That is a good point, the job market for developers is great right now and they've just freed up some talent to hopefully work on something useful.
You have to consider that not all desktop users are alike.
Everybody uses internet, mail, and a few other apps, maybe skype, facebook, netflix, office, things like that.

The metro UI is great for these tasks. It's easy to understand in the current tablet paradigm and those common uses across all users means Microsoft has actually simplified a large percentage of the use cases. Don't tell me you can look at a metro homescreen and not know what to do.

Now, for those of us on HN (I suspect the majority are programmers or sysadmins, or somebody else who wants/needs to get into the guts of the OS), they've got the old familiar WIN32 based OS behind the Metro UI.

Essentially, I suspect the challenge is that it will feel a bit like desktop stuff is virtualized, as I don't think you're running Metro & desktop apps side-by-side (but I don't know as I haven't used Win8 yet).

The important thing to realize is that Microsoft won't be around in a few years if they only catered to those people who are comfortable with the old desktop.

We're getting touchscreens on computers now, and Kinect interfaces I'm sure aren't far behind. The desktop will remain for the small percent of us that use it for work, but I wouldn't be surprised if I use metro much of the time. My concern is how am I going to feel jumping back and forth.
What would be the advantages of applying to YC rather than Lemonos or a hardware specific incubator? I would think initial pool of capital is the biggest hindrance.
If you wanted a dock aka icon based taskbar on Gnome, there were plenty of options before Unity came around. Out of the box they all work pretty much the same. They remain good alternatives if you want to customise. I used to use AWN, worked fine, but I'm fairly happy with Unity. It works very well for window management, and that's really all I want from a dock.

I think the old-school task bar is potentially more useful because it lets you see the window titles at one glance. But it just doesn't scale well beyond a dozen or so windows, either all the text is elided or you end up grouping windows by program at which point you might as well use a dock.
That thing that you said there does not describe Andrew Mason in any way shape or form. He used to post on a forum that I spent a lot of time on in the early 00s. He's a clever, funny guy, and he took most of his lessons in ethics from Steve Albini. Before Groupon, he created The Point which was a group funding site for social initiatives that in many ways resembled Kickstarter.
You guys are pumping out features like crazy! I'm going to use filepicker in my next project whether it needs it or not, great work!
> The other 1% should know that everyone steals from everyone.

This is an absurd justification for the kind of outright theft Zynga has built an entire public corporation on.
Ask HN: How do you store/manage all of the passwords your organization uses?
Have to also keep in mind the price of the mini vs full sized ipad... it's not just dropping $20 (well, $30) per mini sold... there's a lot of nuance in the pricing and consumer perception of the cost vs value of mini vs other products (including full sized iPad...)

Creating a Hacker News Client Using Angular JS
I actually think the weather isn't the largest challenge they are going to have here. All of Las Vegas is air conditioned, and it was probably an affordable time when the city is trying to get large groups in.

The problem is, that deals don't get closed during summer months because people are on summer holidays. You can't get the right people together, so how many of these people are going to organize their summer holidays around this event.

The only plus I see is that it's right before Burning Man, so maybe they'll get a caravan travelling from one event to the other.

I know there are a lot of awkward moments in both of those shows. But it's silly for a person to feel personally embarrassed by those moments.
Plus one to that question. There was a reason the old computer shows of old were in November :-) I always wondered if you could run an un-conference where the conference was 8PM to 5AM each night (the anti-day hours), just take a 'normal' conference schedule and flip the AM's and PM's, and then let people sleep in their temperature controlled rooms during the day. Probably would be great for folks flying in from Europe :-)
Ask HN: How hard it was for you to get initial traction?
Fellow HNers:

I'm sure I'm not the only one on the quest for initial traction of a new (SaaS) startup.

It's long. It's hard. It tries the patience and the sanity. But we're not alone in our quest are we? Nay, we have each other.

Tell us tales of your initial traction. What was it like? How did it feel? What did you try? What worked? What didn't? Where are you now?

Inspire us to continue. Inspire us to persevere. Inspire our dreams.
"And in particular, don't be deterred from applying to Y
Combinator with a hardware idea, because we're especially
interested in hardware startups."

How are you planning on funding hardware startups? From your site:

"Usually $11,000 + $3000 per founder. So $17,000 for two
founders, $20,000 for three or more. Occasionally we
invest more. The goal is usually to give you enough
money to build an impressive prototype or version 1,
which you can then use to get further funding."

A real hardware startup would require at least an order of magnitude more money than this. Unless they walk in with all the required tools, you could burn $20K just in software licenses (Solidworks, Altium Designer, Xilinx Foundation, Keil, etc.) and not have much left for other stuff. Heck, my DSO alone cost me about $20K. The computer I am typing this on probably has $50K in hardware and licenses on it.

I could personally consider the idea of presenting a hardware startup to YC, but I would need to know that this is not about (with the utmost respect) finding a few starving 20-year-olds that will kill themselves for a $20K investment. From my vantage point, if you are not throwing $250K+ into a hardware startup it just isn't going to happen. Of course there are exceptions to every rule. Then again, this ain't my first rodeo.

Now, if the idea is to throw some money at a project to cobble-together a smoke-and-mirrors prototype and then go raise a few million, well, for the right project this could work.

Again, I say the above with respect for what you do. I have done a lot of hardware/software/multidisciplinary development. It's very different from pure software web/mobile startups. Very different.
So it's got all the opacity of an RDBMS with none of the upsides? Great!

Quite frankly, as a developer, I prefer to use flat files (I guess these days we call that NoSQL), but for performance, I often must use Postgres or whatever fits the job.

Yeah... this is exactly why I sold my ipad 2 and just got a new 11" macbook air to pair w/ my Nexus.
RIP Ceefax "Now and Next"! The most useful page on it!

I will always remember the way that if you are on page 643 and you type 641 it will go 644, 645, 646.. and other times randomly just straight to it.
Because the tablet iOS ecosystem is far, far, far better than Androids.

There are plenty of great iPad specific apps.
Doesn't matter if there are exceptions. When there are so many job opportunities out there for developers, why take the risk?
In the old days, I'd have said BlackBerry and BlackBerry Messenger. Now I'd say an iOS device and iMessage.
The New Pot Barons
There are a lot of resources out there about how to build a business, I don't think another short blog post is necessary. You will probably have to leave the startup culture filter bubble to find them I'd guess.

Some links to the authors favourite resources for the basics would have been a good addition surely.
Of course, CLI aren't dead and are in fact still going strong in certain areas. The same will remain true for WIMP in the forseeable future.
What, you don't think systemverilog is the cat's meow? </sarcasm>

I've been in the industry for about 15 years. I agree the languages are horrible. The tools can be buggy, but I don't feel they are all horrible.

There are open source verilog and vhdl simulators out there, although I haven't used them yet [1]. They could be a good starting point for tool improvement. It mentions synthesis as well, but anything practical for hacking would have to target FPGAs and that means vendor tools have to be involved.

While the hardware implementation languages could stand improvement, verification is the largest consumer of resources right now. Being able to work in something like python or clojure for testbenches would be really interesting.

That was before universities were properly resourced.

Universities desperately need to commercialise their research in order to survive.
Perhaps, but it's easier to hide behind the "corporate veil" when you're part of a huge company. You can get away with saying "that's not allowed" at every turn, while the CEO of a 20 person company is much more accessible to help deal with these problems. The reality is that most big companies would be much better off if their CEOs actually knew about issues like this ... I think most of them care about customer satisfaction quite a bit but are insulated from that level of detail.
It is definitely not the "shiny new thing" it once was in the mid-nineties and early millennium, but Scala and Clojure have show that the JVM is a versatile platform that can keep up with the latest trends. I did a summer research internship using Scala and was a very eye-opening experience. I know Sonar (http://sonar.me) uses it in production and it definitely has the potential to grow into a widely-adopted language, especially since more and more people become acquainted with functional programming paradigms.
Unless carriers start offering me several SIMs on one account then I'm not going to pay twice for mobile data.

Hi!

Thanks for this update. This addresses a great security concern so that our buckets cannot be abused (especially filled) from outside of our apps.

I still have a remaining concern which is more about consistency. If you authorize users to upload for your app with a policy, they still can upload anything to their will without your app even knowing about it. Sure, the new policies can ensure that they won't be able to read what they upload if it never reaches your app but they still can upload huge amounts of data in your buckets without that data even being used or known of by the app.

I sure could write a backend scheduled task to clean up unknown files in our buckets.

But, what I would eventually like to see is a way to acknowledge that file handles we're received by the app. If, after a specified timeout no acknowledgement has been received from our app, then these files would be deemed dirty and you would then be able to clean up your servers and our buckets from these files.

Does my concern make any sense?

In any case, thanks again for this update. This remaining concern can be worked around and this update really mitigates the risk of someone wanting to abuse our buckets for malicious reasons.
We've used a few solutions we created for ourselves, and I know LastPass has an enterprise feature, but I'm curious if people have thoughts and advice on tools that worked or didn't work.
A "gerund" is a noun that has "ing" added to it and is used as a verb.
CMS collector has two different types of collections it will do on the old generation. Both are "stop the world" but for drastically different amounts of time. During its 'normal' operation most of the sweep is done concurrently with two short "stop the world" points for each GC cycle. If it can't keep up, then it will do a full blow "stop the world for real" collection.
Trying the demo, loving it so far, just broke it.

At large scale, pure black. At small scale, normal swaying white dots with small transfer point, upwards arrow. Happened after the "you don't have the clearence" cut-scene.

Hey Jeff_29, I work on partnerships at LearnSprout and the best way to get a good look is to just contact both companies. You can reach me at emily@learnsprout.com.
I believe the OP is referring to the industry life cycle. http://www.investopedia.com/exam-guide/cfa-level-1/equity-in...

If the OP is referring to that cycle, his question seems valid to me. Investors choose companies at various stages because they believe they will “exit” (not just VCs, all investors) at a higher level than today. When a company gets to the end of an industry life cycle, their price/earnings multiple is compressed and “value” investors step in thinking their new strategy will let them enter a new market etc.

Every investor is taking risk and whether the timelines are short 2 to 3 years or long 3 to 10 years before the investor expects the company to go in to decline, every professional investor understands that someday the vast majority of the businesses they invested in will fail. (I’m talking about every type of investor, even stable growth mutual funds). Even if that means it takes 20 years to fail.

I understand my point is highly nuanced and somewhat theoretical, but it is grounded in finance literature and the OP’s question seemed more valid than deserving the response, “that’s not how finance works”. I guess I was hoping someone smarter than I would come along and propose some new framework or possibly add some insight so I rebutted your post.
And I just got an email in my MIT email about Zynga interviews..
Unfortunately, WebM isn't _really_ a serious alternative. It's a fine codec and produces great quality video in a similar filesize to H.264, but it's not supported on the majority of mobile devices. H.264 is also what many consumer video cameras produce, like iPhones and most DSLRs.

Pragmatically, I'm happy that all the major browsers (with the exception of Opera) will now support one common codec, even if it's patent-encumbered.
Nice product! Just started using it and realized it's far different than my Yammer and/or Wunderlist. This is especially good for writing simple daily recaps which I can then compress into weekly update to my investors.

It would be awesome if you could notice trends in things I write such as People, Companies, etc so I can search by popular tags.
We are looking at lastPass - looks good so far. (enterprise Ed)

IronStratus is another one to check out lets users keep their own personal passwords and grant access to apps passwords by an admin.

I personally prefer 1password - but it's really single user oriented.

Obviously different from I'd/auth providers like okta or ping identity...but i find there are so many accounts/passwords shared in organizations for services that these guys may not support. (apps with no SSO services for example). Yes, they have some password management tools but they don't seem to have in app/browser shortcuts (ie:chrome/ff extensions).
You make a lot of core business decisions based on whether you are swinging for the fences or building a business from the beginning, you can pretend not to decide but nearly every decision you make at the beginning of a startup is based on this choice.

You can pivot of course, if you stumble on a great revenue source that's small in scale but growing steadily and you aren't getting crazy traction then a startup probably would become a business. But there are legitimate reasons to not become a business and keep chasing the big payout.

In real life you don't find the optimal recurring revenue model, you find options with tradeoffs.
I'm pretty sure Sunstone doesn't charge for tooling if you use their proprietary software. You're locked in, but the costs aren't too bad for development. I'm sure getting the actual gerbers is a pain. ExpressPCB has a similar deal where they will make three index card size boards for $51 total. Not too bad, but they charge ~$60 for the gerbers.

If you're using "normal" software that can generate gerbers, there are other options. If you don't mind long turnaround and overseas fab, Seeed Studio will make boards for ~$1 each, for 5cmx5cm [1]. Slightly more for larger boards.

For hobby projects and prototypes, OSH Park can't be beat. Started as a board pooling coop for open hardware, they now send out batch jobs a few times a week to Amitron in IL and produce high quality boards (ENIG, with silk screen and soldermask) for $5/in^2 (for three copies, so a 1.5in^2 board would be $3.75 each)[2]. Their ordering process couldn't be better--upload gerbers, approve an on-screen rendering, specify the number of boards, and enter your billing info. No confusing options to go through. Seriously, try it. It's awesome.

So board fab is not that expensive anymore, and perhaps cheaper than when you last looked. The turnaround times aren't great for the inexpensive options, but with luck or good EDA it's possible to get by without too many iterations.

The thing is, you're paying a premium to Amazon because Amazon is so popular and the Kindle makes it so convenient to buy ebooks, that you can hope for greater profit by simply selling more copies on Amazon, even if the per-sale profit is lower.

The "you cannot sell for less elsewhere" rule is bullshit though.
>What type of horror stories have you worked on?

If you're a developer, then you know what sort of ridiculous proposals are common.

"Build my facebook clone for absolutely zero pay, but I'm feeling gracious so you get 15%!"

I do, however, like the idea of working on granular bits of startups and distributing my risk in a way that makes me more likely to have something take-off than committing to a single startup but not necessarily having any more control than the 'freelancer' mode.

What for? At this point, forking android would create something more proprietary than android itself.
