I came here to say this too. This article doesn't have a date on it, so I can't tell if this is the chicken or the egg. I suspect that this one came second. If that's the case, it would have been nice for the author to acknowledge the original post in his introduction.
I like the sodium fast reactor: low pressure, moderate temperature, sodium is dirt cheap, high burn-up of non-uranium/plutonium products ("waste"), and plutonium need never be separated from other reaction products.

The article doesn't say, but because molten salt reactors use liquid fuel, they release the radioactive xenon gas produced by uranium fission. (In fact this is sold as a benefit, since xenon absorbs neutrons better used for the chain reaction.) Xenon is a noble gas and therefore volatile, so the reactor will need strenuous containment measures. Loss of the gas seal would result in significant radioactivity release.

Helium-cooled reactors may be constrained by shortages of helium, which is rather rare and difficult to extract on Earth. You'd hope that government program managers would have worked out the logistics of this, but they tend to not see things that would get their funding cut. (Argon is plentiful but might not be a substitute because it reacts with neutrons a lot more than helium does.)

I'm a fan of liquid fluoride thorium reactors (LFTR). The prevalence of Thorium is a big positive and the ability to process out existing nuclear waste is a tremendous boon.

We're not that far away from commercializing LFTR. It's a shame we can't find more research funds.
If it's not a groundbreaking idea that can be monetized, particularly one that's both helpful yet easy for others to replicate as you say... I'd be tempted to open-source it if it were my baby, but the call is yours alone.

You can always attempt to patent the idea and sell it, or if it really is groundbreaking, try to turn it into a product or a service. That's how many startups get off the ground.

I think you'll rarely go wrong giving away small useful programs as free software. It's the easiest way to get users, and once you have users you'll learn even more about how to make the software better. If you're lucky you'll find other people who want to contribute, and you'll get a chance to work with them and meet them. And an original free software project is a great thing to be able to show off. If it's indeed a small amount of effort to duplicate, then there's probably not that much selling opportunity that you're giving up.

If you do a good writeup and post it to Hacker News and Reddit, you can probably get some good feedback and a little notoriety. I got some really helpful comments that way on my last little useful project.
Argh. The "And ..." paragraph should have been before the "Govts select" paragraph.
It's because the original usage is rather technical--I've only seen philosophers use it, and only then as the adjective "question-begging".
But for all his ignorance, it is a damn entertaining piece if you've never read it before - and if the year is 1998.
You are confused by the implications and meanings of the results of Godel.

There are two (popular) axiom systems of the natural numbers. Both are from Peano. One system is first order and the other is second order. The second order system is not recursively enumerable. The first order system is.

At the beginning of the 20th century mathematicians were looking for a first order system that would encapsulate all true statements of the second order Peano system. The reason for this is because a recursively enumerable system is computable. The second order system is not.

Now there is a only one model of the second order Peano axioms (up to isomorphism). This model is the natural numbers we all know and love. What Godel showed was that there is no first order system capable of encapsulating all true statements in the integers (the model we all know and love).

If you have a statement that can't be disproven then it is true. A statement is true if and only if there is no counterexample to it in any model of the axiomatic system you are dealing with. That's what the Completeness result is. So, if you have a statement for which there is no counterexample in any model then it's true. This is what the Completeness result is all about.

The statement you made:

" It says that in any sufficiently complex axiom system there will be statements that it can neither prove nor refute, "undecidable" statements."

is incorrect. Just take a model and collect all the true statements. Voila, you have an axiomatic system that is complete. Do this for any model and you have a complete axiomatic system. If your model contains the natural numbers then this complete axiomatic system isn't computable.

This is a fair point, but people do update their websites. Some people, some of the time. Still, I'll update my post to note that.

The problem is that 100% code coverage is not nearly enough. Take this Python function:

def f(x, y):
return x + y

and this test function:

def test_f():
assertEqual(2, f(1, 1))

There you go, 100% code coverage. Unfortunately we have covered next to 0% of what could possibly go wrong here.
Also, deleted comments probably don't get their id's reused.
That deal just looks iffy. A sub-million dollar takeover for a site with 16 million active users ? - at a few cents per user there should have been a good half-dozen competitors willing to purchase. But it ended up having assets sold below market value to a group part owned by one of the current owners. That seems the kind of activity that would get you on the receiving end of a fraud investigation.
With a business model that is dependent on licensing content from organizations like the RIAA, I think it came down to liabilities and licensing costs more than anything else.

I dont think so. Sure, the signal to noise ratio is declining on the web, but we dont have to depend on Google to deliver things that interest us. I think HN is a reasonable model for a filter. Sturgeon's Law certainly applies here, but I manage to find a few posts that follow my interests. Most of the time the comments are more relevant than the link.

HN is really crowd source editing with a very high level of participants. I dont see any sign that purely statistical aggregation is going to cut the mustard soon.

Would it be possible to use Open Office with this or IBM Lotus Symfony?
I've checked out Arc before, and it looks pretty neat. Perhaps it could handle some of the "simpler" part of the application, and I let Python handle some of the more intense server-side implementation. Would that be unwise – combining two (similar) languages in one app?

Thanks for the advice! It sounds as though I need to just get a version 1 out there, ASAP.

A problem with my idea is that it requires some pretty intense sysadmin knowledge, and my big stumbling block is either learning more about all that, or bringing in a partner.

Another issue, perhaps you've got suggestions regarding it, is security. How do I go about handling that? Passwords, information, etc?

Thanks again!
I'll do that – write out a list based on the business plan and try to navigate the fastest way through it to launch.

Thanks for that – it gets overwhelming to consider all the project at once.
Well, you still need to take its debt into account as well, which I'm assuming Imeem has quite a bit if it sold for so low with 16 million users. A company with $10M in debt, for instance, that's purchased for $2, is really a $12M acquisition.
Interestingly enough, fractional reserve banking is not significantly different from the way any other business works.

If I loan money to a business, that business almost always does something with the money, like buy stuff or pay expenses. It doesn't keep the money sitting around to pay me back. If things go wrong, the biz won't have money to pay me back.

Let's compare that with the Wikipedia description of fractional reserve banking. "The fact that banks are required to keep on hand only a fraction of the funds deposited with them is a function of the banking business. Banks borrow funds from their depositors (those with savings) and in turn lend those funds to the banks’ borrowers (those in need of funds)."

Yes, there's the quibble about "demand deposits" vs other kinds of loans, but that doesn't really have anything to do with the expansion in the actual money supply.

Yes, I know that the article defines "money supply" as "cash plus demand deposits". However, as a loan matures, it becomes closer to a "demand deposit" and eventually becomes one. The original money, meanwhile, has already left the biz. Maybe some came back, maybe it didn't. Either way, the only thing that's there for sure is the obligation to pay.

Note that a bank has loans as assets. A biz has whatever it got in return for the borrowed money that it spent. Either one can go bad.

I believe there's very limited role of "design" when it comes to application development: people want consistent look and feel in all apps, they want to reuse their skills and not having to re-learn how to add an item to a list for every little piece of software.

It doesn't mean that everything needs to look like crap for the sake of consistency: just look at Cocoa-based software: you don't need a designer to build a great looking GUI on a Mac.

Why is web different? Because it stands with one foot in its past: a UI screen is treated like a "page", a magazine cover, hence the false need for a designer. The result? More often than not you get a gypsy blanket instead of a modern user interface.

This reminds me of the DOS era when developing a graphical application felt like building a game: you needed to design buttons, scrollers, etc. Yeah, funny I haven't thought about this before: web-based GUI feels a lot like MS DOS apps: for a developer as well as for the user.

He's saying that the mass-produced crap "content" sites will all dominate the search result listings and push all the quality content sites out of business because noone will visit them.

But we're not using search engines to get to every place on the web. We learn where the quality content is, we don't rely on generic portals for news and articles. We learn which blogs are good. We get sites recommended by our friends. We find sites and bookmark them and revisit if they're good.

A subdomain of 'news' in this context is everything that ends on news.ycombinator.com. That is what you are asking for.

Technically speaking ycombinator is a subdomain of com and news is a subdomain of ycombinator.com and so on.

www.news is not a valid subdomain name afaik, because it incorporates the separator in to the domain name.

So to make things work like you suggest a subdomain of news.ycombinator.com would have to be created.
There needs to be a self-hosted platform for this hooked up directly to the artist's bank account. It's ridiculous to implement the middle man that is a digital program instead of a retarded record exec. Zed Shaw has talked about this a tiny bit. I've thought about taking over the defunct open source OpenTape project which was born out of Muxtape's demise. Add in a simple payment engine for songs (hook up to your paypal, bank account via amazon,etc.), along with making the flash widget nicer with links to download. Make it completely open source. If an artist doesn't want to deal with the tech, charge for the self hosted version, and let them keep 100% of revenues after payment processing.
I've read that article; I was talking about the general trend of investing and why they were chasing returns that had such inherent risks.
I'm not quite sure what you mean by "it should tell us something." So, I apologize in advance if the following is a misunderstanding. (For the record, I don't much care about someone's HTML per se. I'm talking about presentation. I'm not being a web standards fanatic, if that's what you meant.)

If you mean that they are all substance and no frills and that that's a good thing (or something along those lines), I would argue that presentation matters. You don't have to follow the latest fashions, but Crockford's site makes it literally hard to read his (excellent) articles. There are no margins. The line spacing is painful. Applying Readability to that page makes the article not just prettier but more substantive (because I can draw the meaning from it more easily).

Giving literally zero thought to the visuals of a webpage is comparable to giving literally zero thought to the order of a presentation or paper. All writing is partly about communicating, and giving no thought to such things is not cool and intellectual. It's likely to be lazy or pretentious.

In firefox you could even type "news ycombinator" in to the url bar and hit enter.

Apparently it uses the first result from google.
I completely agree. People will simply adapt and find new ways to locate quality, original content. If HN-like sites are the solution they will take over. If not someone else will come up with a solution.
Does this mean some form of mystery about oneself must always remain? Assume complete self-referentiality of a being. Then the ultimate source of one's goals is no longer the black box called "my nature". What is it then? And would it be the same for two completely self-referential being?

(By self-referential I mean one who understands oneself absolutely; one who possess a perfectly accurate map of oneself. There probably is a better word.)
I'll bet you didn't test that before you wrote that.

Hint: it works just fine.
"Force you to think" is basically the idea, yes. The goal is to catch places where your high-level conceptual understanding of the task to be accomplished doesn't match the lower-level model of "how to get from here to there" you've mentally constructed, usually at weird corner cases.

There's roughly three places where a programmer can make a mistake--understanding a task to be done, creating an algorithm to perform the task, and describing the algorithm to the computer. Type checks help insure that the algorithm you intended to code is what you actually coded; tests can help ensure that the algorithm you coded actually performs the task you think it does.

If money flows from one part of the government to another, there is no reason why it wouldn't flow through private banks. The government isn't one monolithic agent with a single (overdrawn) checking account.

Whether you count the Fed as being within "the government" is a complex issue but ultimately it is just semantics and doesn't change the nature of the situation. They are in a grey area with some private and some public characteristics, like the post office.

I have some feedback:

- I was totally confused how to launch this
- I couldn't discern any benefit of this over phpPgAdmin minus the nicely done interface
- I couldn't discern any benefit of this over Aqua Data Studio, NaviCat, et al. sans pricing.

I'm really curious why you chose to do this as a web app. If the benefit is to give "managers" and others access to the database to run reporting, where is the graphing, pivot table, etc support? If it's to give other developers access, your desktop counterparts (specifically Aqua Data Studio) provide tools you are lacking (code completion, diagramming). Granted there is a sizable price difference, which could be a selling point, but again phpPgAdmin does all that you do and is free and extensible because it's OSS.
Yes. If you haven't tried it, run and do it now. It's one of those "I can't believe nobody thought of this before" moments.

I know about the problem.

RightJS is extra careful with native classes extensions, it adds only standard methods and doesn't extend the Object.prototype at all. In many cases it's just adds missing methods in old browsers and that's it. And we always keep the original functionality intact.

We're trying to balance between the Prototype extensions hell and jQuery agnosticism. Things like String#endsWith, Array#compact is kinda standard features, they are extremely handy in everyday work and most of soberminded programmers won't hack those methods if they create some plugin that other people might use.

As the matter of fact most of jQuery plugins don't extend prototype too.

So it is a problem, but I believe it's negotiable and there might be a non-polar solution.

I recently wrote a pre-commit hook that runs pylint on my Python files.

http://fitzgeraldnick.com/weblog/9/

“git diff –staged –name-only HEAD” will get you the files that are about to be committed and then you can check if they end with “.php” (or “.py” in my case) and go from there. I also check to see if “#!” and “python” are in the first line of a file because my pre-commit hook is written in python but doesn’t have an extension, just a crunch bang.

From http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html:

"14.29 Last-Modified

The Last-Modified entity-header field indicates the date and time at which the origin server believes the variant

was last modified.

Last-Modified = "Last-Modified" ":" HTTP-date

An example of its use is

Last-Modified: Tue, 15 Nov 1994 12:45:26 GMT

The exact meaning of this header field depends on the implementation of the origin server and the nature of the original resource. For files, it may be just the file system last-modified time. For entities with dynamically included parts, it may be the most recent of the set of last-modify times for its component parts. For database gateways, it may be the last-update time stamp of the record. For virtual objects, it may be the last time the internal state changed.

An origin server MUST NOT send a Last-Modified date which is later than the server's time of message origination. In such cases, where the resource's last modification would indicate some time in the future, the server MUST replace that date with the message origination date.

An origin server SHOULD obtain the Last-Modified value of the entity as close as possible to the time that it generates the Date value of its response. This allows a recipient to make an accurate assessment of the entity's modification time, especially if the entity changes near the time that the response is generated. "

The word 'caching' is not mentioned in there at all, those are completely different headers, see the 'cache control' headers in that same document.
