Risky, we-can't-fail, all-or-nothing science - <AUTHOR> http://www.cbc.ca/technology/story/2008/09/26/f-strauss-outreach.html?ref=rss <comment><USER3> This is a huge, huge article for startup folks to read. It starts a little slowly, but after that my interest grew with each paragraph until the conclusion, which was 100% spot-on.

<comment><USER4> "As background, fusion is the physical principle by which the sun produces heat and sunlight as it fuses together hydrogen atoms, not to mention being the _chemical_ reaction that unleashes the H-bomb's lethal and terrifying force."

On reading this I was doubting the value of the article. I shall continue . . .

edit: Later on there is also the following

The exhibit "tried to explain to people how the reactor would work, why it was a good thing ( _no radioactive waste left after the reaction_ , for one, and no greenhouse gases are produced) and why it was hard to do."

I'm getting out of my depth here but it was my understanding that thermal fusion releases large numbers of neutrons which lead to the containment vessel to slowly become radioactive. I would love to be corrected.

<comment><USER5> You are in fact correct already. One of the research goals of ITER is to experiment with different materials being subjected to the neutron flux in order to determine the radioactive byproducts and their theoretic half-lives. They are also proposing that the neutrons be used to facilitate the production of tritium from lithium and hydrogen as well as using the neutrons as the main source of energy output for the system.

While the article is extremely interesting I find that costs and time periods for this kind of science are misrepresented. Not that $5 billion isn't a lot of money, but it is on par, if not lower than many other energy projects. The Alberta Tar Sands alone have had more than $30 billion invested in the past decade. It also does not come close to the investment originally made into fission power production and continually made to produce next generation reactors. Without 'risky science' we don't move forward. Our efficiency may increase; a better stone for making axes means a tree can be cut faster, but by making great leaps forward in science, we may no longer need the axe, or even the tree. The ITER, the LHC, the Manhattan Project, are (were) investments in our future and the future of science and understanding. While some of these projects may fail, the cost of not trying is far greater.

<comment><USER6> _It also does not come close to the investment originally made into fission power production and continually made to produce next generation reactors._

The difference is that there is no place in the market for fusion reactors. In light of the existing half-billion-year [Edit: half- _trillion_ -year] fuel supply for fission reactors, the drive to create fusion reactors is nonsensical.

<comment><USER5> I believe the same argument was used for why we should just stick with oil.

The energy density and potential output is far higher (theoretically) with fusion than with fission. You may also want to check your figures on the half a billion year fuel supply. At current rates of use, uranium fuels will last about 1000 years. Thorium is an alternative option for fission power; however, this is yet unproven in large scale deployment. There is also the fact that fusion reactors will produce far less high-level (long half-life) radioactive waste.

50 years ago, and even today, critics believed that there was no place for fission power but now it appears to be our greatest alternative to providing base load power over hydrocarbon based plants. The uses of fusion technology are not only limited to power production either. Fission power has resulted in advances in materials, medicine, the understanding of basic atomic science. There is no doubt that properly understanding fusion will lead to many advances in other fields.

<comment><USER6> _The energy density ... is far higher (theoretically) with fusion than with fission._

Is that true by volume of fuel? By weight, the energy density is only 4 times as high (D-T) ([http://en.wikipedia.org/wiki/Energy_density#Energy_density_i...](http://en.wikipedia.org/wiki/Energy_density#Energy_density_in_energy_storage_and_in_fuel)). By volume, the density of uranium/thorium might very well be typically higher, since uranium/thorium is a heavy-metal, and therefore notably dense.

For convenient fuel storage, the deuterium and tritium might be temporarily be converted to water. I'm not going to do the math right now, but I think it would be interesting to see how that compares volumetrically to uranium/thorium energy density.

      .

_The ... potential output is far higher_

Please clarify.

      .

_At current rates of use, uranium fuels will last about 1000 years._

There are more than 40 trillion tons of uranium in the earth's crust (mostly in the continents, and mostly near the surface of those continents):

<http://nuclearinfo.net/Nuclearpower/UraniuamDistribution>

The world currently uses ~60,000 tons per year of uranium. <http://www.world- nuclear.org/info/reactors.html>

~60,000 tons/year / 60x breeder-factor / 2.5x thermal-efficiency improvement = 400 tons/year fuel use. 40 trillion tons of uranium / 400 tons used/year = .1 trillion years of uranium.

Thorium is available in the crust at some 4 times the ubiquity of uranium = .4 trillion years of thorium.

Adding the uranium and thorium together gives us .5 trillion years of fission fuel.

      .

How did you come up with _1000_ years? Even limiting ourselves to the mere 9 billion tons of uranium/thorium present in seawater would provide 20 million years worth of fuel. ...And that supply is constantly being replenished by rivers, and by the seabed (the uranium/thorium suspended in the oceans is in equilibrium with that on the seabed -- if some is taken out, it is creates disequilibrium that can be relieved by the seabed uranium/thorium dissolving into the seawater).

<comment><USER5> Here are the energy densities in MJ/kg: Deuterium-Tritium fusion - 337,000,000 MJ/kg Nuclear fission (of U-235) - 88,250,000 MJ/kg Natural uranium (99.3% U238, 0.7% U235) in fast breeder reactor - 24,000,000 MJ/kg Enriched uranium (3.5% U235) in light water reactor - 3,456,000 MJ/kg Natural uranium (0.7% U235) in light water reactor - 443,000 MJ/kg

The higher output is a function of the higher energy density.

Your numbers may be correct about how much uranium there is in the earth's crust but you are missing two very important points. Only a tiny fraction of the uranium is in concentrated enough deposits to allow for economic recovery of the mineral. This and the fact that U-235, the fissile isotope of natural uranium, occurs in only 0.711% of uranium containing minerals leaves only enough uranium with reprocessing for the next 1000 years.

[http://www.world-nuclear- news.org/ENF_Exploration_drives_ura...](http://www.world-nuclear- news.org/ENF_Exploration_drives_uranium_resources_up_17_0206082.html)

Thorium required a breeder reactor in order to produce the U-233 necessary for fission, and as stated in another comment, these reactors are still in experimental stages and have a much lower level of operational safety record.

<comment><USER6> _Only a tiny fraction of the uranium is in concentrated enough deposits to allow for economic recovery of the mineral._

Given that that very point was addressed at the link I provided, one might suspect that you did not visit it before answering.

It is not merely 40 trillion tons of uranium that are in the crust. It is 40 trillion of uranium that is also economically-recoverable. Why is nearly all of the uranium in the crust is economically-recoverable? It is because the energy density of uranium is so high. The same goes for thorium.

<comment><USER5> On the contrary the article you provided did not once mention the words 'economically recoverable'. What you are looking for is the _reserves_ of Uranium in the world. Reserves, in mining means the amount of ore that can be economically removed from the earth. For those numbers please refer to the link that I listed previously. If the percent of uranium oxide in an ore is less than 0.1% (by weight) then it is not economical to mine.

<comment><USER6> _Reserves, in mining means the amount of ore that can be economically removed from the earth._

No, it doesn't.

[http://www.google.com/search?q=site%3Ajuliansimon.com%2Fwrit...](http://www.google.com/search?q=site%3Ajuliansimon.com%2Fwritings%2FUltimate_Resource+reserves)

<comment><USER5> Julian Simon was a professor business administration, not a mining engineer. Those articles refer to scare tactics presented in terms of resource scarcity by environmental fanatics. He says nothing about the definition of a mineral reserve. But I can help us with that.

 _Reserve definition

Reserve definition is undertaken to convert a mineral resource into an ore reserve, which is an economic asset. The process is similar to resource evaluation, except more intensive and technical, aimed at statistically quantifying the grade continuity and mass of ore.

Reserve definition also takes into account the milling and extractability characteristics of the ore, and generates bulk samples for metallurgical testwork, involving crushability, floatability and other ore recovery parameters.

Reserve definition includes geotechnical assessment and engineering studies of the rocks within and surrounding the deposit to determine the potential instabilities of proposed open pit or underground mining methods. This process may involve drilling diamond core samples to derive structural information on weaknesses within the rock mass such as faults, foliations, joints and shearing.

At the end of this process, a feasibility study is published, and the ore deposit may be either deemed uneconomic or economic._

from <http://en.wikipedia.org/wiki/Mineral_exploration>

<comment><USER6> For resources to be counted as reserves, they have to be found. If no one bothers finding more resources, the resources that lie in wait are not counted as reserves. Here is some finding-cost data:

<http://www.world-nuclear.org/info/inf75.html>

 _the finding costs of crude oil have averaged around US$ 6/bbl over at least the past three decades. When finding costs of the two fuels are expressed in terms of their contained energy value, oil, at US$ 1050/MJ of energy, is about 300 times more expensive to find than uranium, at US$ 3.4/MJ. Similarly, the proportion of current market prices that finding costs comprise are lower for uranium. Its finding costs make up only 2% of the recent spot price of US$ 30/lb ($78/kgU), while the oil finding costs are 12% of a recent spot price of US$ 50/bbl.

By these measures, uranium is a very inexpensive energy source to replenish, as society has accepted far higher energy replacement costs to sustain oil resources._

      .

If those finding costs were considered too high, one would additionally have to hope that no one would be able to find the sea, or that if anyone _were_ able to find the sea, that they would not be able to figure out how to extract uranium from it for, perhaps, only several hundred dollars per kg -- something which in fact has already been done, and which is being improved-upon by current research conducted by Japan and India.

<comment><USER5> Current extraction from sea water runs over 4 times the current spot price for Uranium. It is currently an UNECONOMICAL way to get Uranium.

Please reread the original article I linked to regarding the 1000 year supply. It actually deals with undiscovered reserves.

 _In addition to these identified resources, the category of uranium that could be expected to be found based on the geologic characteristics of known resources has grown by 500,000 tonnes to 10.5 million tonnes.

The data comes from Uranium 2007: Resources, Production and Demand - <USER2> known as the Red Book - published every two years by the OECD Nuclear Energy Agency (NEA) and the International Atomic Energy Agency (IAEA)._

from: [http://www.world-nuclear- news.org/ENF_Exploration_drives_ura...](http://www.world-nuclear- news.org/ENF_Exploration_drives_uranium_resources_up_17_0206082.html)

<comment><USER6> _It is currently an UNECONOMICAL way to get Uranium._

The word "currently" is important here. It means that the statement containing the word is irrelevant in the long-term. Resource supply-size increases exponentially to linear increase in price. How high of a price increase can the market accept? The current uranium prices contribute about .2 cents per kWh of electricity produced.

<http://www.world-nuclear.org/info/inf02.html>

Multiplying the uranium price by 10 causes it to contribute only 2 cents to the cost of each kWh of electricity produced. That is before further fuel- efficiency advances are applied, which the higher fuel prices would incentivize.

      .

Do you mean to suggest that at some $1,000/kg, it would not be possible to profitably extract some 60,000 tons or more of uranium per year from seawater? What about at $2000/kg? $3,000? $4,000? $5,000? We can keep going, since fuel- efficiency of the plants can continue to be improved. $6,000? $7,000? $8,000? $9,000? $10,000?

Where is your cutoff for economic seawater uranium mining?

      .

_Current extraction from sea water runs over 4 times the current spot price for Uranium._

That would make it cost less than a penny per kWh. Are you meaning to suggest that the electricity market would not accept a fuel-price of under a penny per kWh?

<comment><USER5> It's good to know that there are other people who are great promoters of nuclear power (I am a huge fan), but you're not reading your sources very well (the last article you linked to put the cost of uranium as nuclear fuel at 0.5c/kWh at a spot price of $53/kg), your math is full or errors and you clearly haven't researched exactly what goes into taking uranium from the ground and using it to produce power, or the related fields, such as energy production and consumption in general, mineral exploration and mining, or waste management. You fail to take into account production levels (which are currently only about 65% of consumption), an increase in uranium demand (based on new and proposed build will double by 2020), increased costs of actual mining and transportation of the resource just to name a few, or the effect of mining and extracting ever bit of uranium from the planet. There are limits to fuel efficiencies increases and as well to the economic viability of nuclear power. This is why it's a good idea to invest in new technologies now, such as fusion (the whole reason this discussion began). Sure we can take every last particle of uranium out of the Earth's crust and ocean's but I think we can spend our time, energy and effort doing something more productive. Uranium and thorium are finite resources and no amount of water extraction will make them not so. We once believed oil would last us forever and we have come to realize that this is not so. Let's not make the same mistake by promoting unsubstantiated and irrational ideas that nuclear (fission) will last us for half a trillion years when very educated and informed people who are actual experts put the number at 1000 years. As a nuclear enthusiast, I'm fine with the 1000 years because I hope that by then we have something better that nuclear (fission) to get our power from.

<comment><USER6> _It's good to know that there are other people who are great promoters of nuclear power (I am a huge fan)_

Please keep your bigotries to yourself, and don't speak for what mine might be.

      .

_you're not reading your sources very well (the last article you linked to put the cost of uranium as nuclear fuel at 0.5c/kWh at a spot price of $53/kg)_

That would be the total cost of the fuel after conversion, enrichment, and fabrication. The U3O8 cost of $472 is .264 of the total cost of $1787, which indeed works out to less than 0.2c/kWh (about 0.131c/kWh, actually) if $1787/kg of fabricated-fuel works out to 0.5c/kWh.

2007 fabricated-fuel costs at U.S. nuclear powerplants were 0.47c/kWh. [http://www.nei.org/resourcesandstats/nuclear_statistics/cost...](http://www.nei.org/resourcesandstats/nuclear_statistics/costs)

      .

_your math is full or errors_

Please provide at least a single example of any math errors I might have made.

      .

_We once believed oil would last us forever and we have come to realize that this is not so._

Indeed, there might only remain some 70,000 years' worth of oil.

Chandrayaan sends images of Apollo 15 landing - <AUTHOR> http://timesofindia.indiatimes.com/news/india/Chandrayaan-sends-images-of-Apollo-15-landing/articleshow/4964829.cms

<comment><USER2> No amount of solid evidence has ever detracted a conspiracy nut from their pet subject, I don't see why it would be differently this time.

Let's see:

<conspiracy_nut_mode>

       - the Indians are conspiring with the Americans

       - the Americans have interfered with the transmissions from the satellite

         - subtheory 1: they have planted a spy in the place
           where the satellite was assembled and tampered with
           the software

         - an American satellite in orbit around earth
           messed with the image in transit

</conspirace_nut_mode>

And that's without trying really hard.

And by having all these people falling over each other to say that this 'rubbishes' the claims of the conspiracy theorists they're giving those idiots way too much credibility, the best thing to do is to ignore them. Post the pictures (which none of those sites do, by the way!) in as high a resolution as you've got and let the rest of the world enjoy them. The nutters will do their thing anyway.

The Chandrayaan satellite is a pretty good way for India to show the world that they have a space presence, it can do all kinds of useful stuff, let's not diminish it by just using it to give attention to a bunch of people that really don't deserve any.

The media are very much complicit in giving these fools airtime, let's see them give airtime to Chandrayaan without being tied in to that nonsense.

<comment><USER3> \- I always thought it would have been much harder to fake the footage of the moon landing and takeoff with 1969 FX technology than it would have been to actually land on the moon.

\- If you can already go into space what's so hard about landing on the moon?

\- The Soviet Union would have been all over it in 1969 to score points if the US had faked it.

\- People shouldn't mix up Capricorn One with reality. Particularly as they couldn't keep the astronauts in the movie quiet.

<comment><USER2> Absolutely, those are all very valid and have been rehashed endlessly, but if those didn't convince the weirdos out there a bunch of pictures isn't going to make much difference. The risk here is that people will start to think this was the main objective for the Chandrayaans mission.

Nutcases thrive when you give them a platform, this not only gives them yet another reason to get plenty of airtime but makes it worse by actively addressing them instead of just ignoring them. They're now 'officially' part of the game, instead of relegated to the fringe where they belong.

'Moonlandings', 'hoax', an article that makes claims without the image to back it up, great factors for a bunch of stories in a slow news month, this will get plenty of airplay.

Ask HN : How to check multiple keyword positions on Search Engines? - <AUTHOR>

Hi Guys,
I was wondering if anyone could recommend a tool we could utilize to monitor our keyword position across the search engines on a fortnightly basis.
If we simply had 30 or so Keywords / Keyword phrases utliized across the entire site I would of course manually perform the queries or use some sort of Keyword Checking tool on an SEO site.  Unfortunately we have over 1000 Keywords / Keyword phrases throughout the site!
Any ideas would be great.

A massive data dive proves that languages and genes evolve together - <AUTHOR> http://qz.com/336504/a-massive-data-dive-proves-that-languages-and-genes-evolve-together/ <comment><USER2> Doesn't this perhaps show selection based on language? People who speaks similar languages are more likely to interact and reproduce, eventually narrowing the gene pool.

<comment><USER3> No, this is purely correlative. That's why I, with South Asian genetics, am able to speak a language with no voiceless retroflex stop natively without accent.

<comment><USER4> You might have misunderstood GP (or I might have misunderstood you).

What GP is saying is that people with the same language interact more with each other and therefore reproduce, thus narrowing (averaging?) the gene pool to the speakers of that language.

Not that you'd be unable speak a language because of your genes! The cause- effect GP proposed would be language -> genes, not genes -> language (which is what I guessed you meant to refute).

<comment><USER3> I'd also dispute the likelihood of that. Genes change slowly, language changes quickly. It seems unlikely that language could then drive genes on a global scale.

</comment></comment></comment></comment><comment><USER5> Linguists must be rolling their eyes at this study. If you want to study language evolution, phonemes are the last thing you should look at. Languages change, fast, and the sounds of a language change drastically over generations. Compare modern Icelandic and Old Norse (by which we usually mean Old Icelandic)—Icelandic is supposed to be one of the most conservative languages and is still quite close to Old Icelandic in spite of centuries of separation in areas like syntax and vocabulary. But if you compare the pronunciations, they are quite different. The sounds of a language are among its least stable aspects.

Similarities in pronunciation between languages spoken over the same region are part of a phenomenon well known to linguists and do not imply that the languages are related. For example in terms of a pronunciation feature called coda devoicing, Slovene dialects near the Austrian border will pattern with German, those near the Croatian border will pattern with Croatian, while Standard Slovene will have something in the middle. Slovene and German are only very distantly related.

There may be something there about closely related population groups ending up using similar sounds even if their languages are not closely related, but I doubt the researchers even thought about that and used phonemic distance as a shorthand for actual linguistic distance.

</comment><comment><USER6> I am always very leery of big-ticket science published in the Proceedings of the National Academy of Sciences (PNAS), as this paper is. Many papers (including this one) are not subject to peer review because they use what has been called the "inside track" ([http://www.nature.com/news/scientific- publishing-the-inside-...](http://www.nature.com/news/scientific-publishing- the-inside-track-1.15424;) though note that Nature is not a disinterested observer). This paper was "contributed" to PNAS, which means that the authors reached out a member of the National Academy of Sciences (usually a famous late-career scientist) who they believed would be sympathetic to the line of work, and asked this person to serve as contributor (essentially a type of action editor) on the piece. Importantly, this person (Marcus Feldman) happened to be a colleague of the first author (she appears to be a postdoc at Stanford, he is a professor at Stanford, and they have written papers together), but the conflict of interest is ignored. Unlike a normal action editor, however, the contributor is not expected to identify potential adversarial reviewers, or even to take negative reviews into account! As a result, a significant minority of PNAS "contributed" papers clearly wouldn't have made it past peer review elsewhere. Famously, the 'contributed' track has been widely abused (e.g., by Linus Pauling, who hoped to beat Crick & Watson to discover the structure of DNA--unfortunately, his structure is clearly wrong.)

I am not saying that this is the case for this paper. However, I note that there are no linguist authors, no linguist reviewers, and no linguist editors, involved in the process. And, as a linguist, I don't understand the motivation for this work. The presence of a phoneme in language X and language Y tells me next to nothing about the relationship between X and Y; there is no theory of "phoneme evolution" because the evolutionary metaphor is irrelevant at best (there is no analogue to selection). And we've known for centuries that unrelated languages in close contact may borrow phonemes from each other (retroflex t in South Asia being the parade example), and obviously close contact will lead to genetic transfer too.

</comment><comment><USER7> This is interesting research, but it's also completely unsurprising. As human populations migrate, expand, collapse, invade, mix, and die out, both their culture and their genes will do all those same things.</comment>


Ask HN: Things to consider when choosing an investor? - <AUTHOR>

HN-
I don't even have a product yet, but did a quick pitch on the phone to an investor and he is potentially interested in investing in a MVP-level version of the product.
What are the most important things to consider with choosing an investor (considering you have the choice) ? What should I be looking out for?
Thanks! <comment><USER2> Terms, terms, terms.

Also, ask yourself (and perhaps the investor) what would happen if in three years, that money's gone, your product tanks, and have to get yourself a job. There are many investors who get emotional and make it their life's work to torment you when things go south, no matter what they sign or what they promise. Some are even accredited, but making sure they're accredited will limit your exposure to this eventuality. (They should have forms they can fill out and give you to prove it).

If the investor passes that test, then as long as you can live with the terms (convertible notes are always best if you can get them versus straight equity), close 'em and get building!</comment>

The Prime That Wasn't - <AUTHOR> http://zmievski.org/2010/08/the-prime-that-wasnt? <comment><USER2> That's not a true Regular Expression: it uses back-tracking, and to the author's credit, he notes that in the article.

True regular expressions can't recognize primes. It's important to keep these kind of distinctions in mind for two reasons.

First, without clear, precisely defined categories of formal languages, you'll fail to recognize unsolvable (or undecidable) problems and waste a lot of time. Personally, I put "malware dectection" in this category, as determining whether a given file constitutes a virus seems equivalent to solving the halting problem.

Second, sloppy usage like using "Regular Expression" for something else is one of those common usage issues that allow people to argue based on the name ("regular expression") to lure the unsuspecting in, but then fall back on extreme technicalities to trick people into agreeing with the argument when they might not otherwise have agreed. A lot like I've done in this comment.

<comment><USER3> To see some genuine regular expression trickery, see <https://github.com/matthiasgoergens/Div7/blob/master/regex7> for a regular expression that recognizes decimal numbers that are divisible by 7.

If you memorize that expression, you have a handy way to tell whether a number is divisible by 7.

<comment><USER4> It's much easier to remember and apply the corresponding finite state machine, where you just keep track of the remainder mod 7 that you've seen thus far. Example: 48193. What's the remainder mod 7?

48 mod 7 = 6 -- First two digits

61 mod 7 = 5 -- Remainder thus far, appending next digit

59 mod 7 = 3 -- Remainder thus far, appending next digit

33 mod 7 = 5 -- Remainder thus far, appending next digit

No more digits, so the answer is 5.

(Edit: I did figure that you were almost certainly being sarcastic. I just wanted to point out that in its corresponding FSM form, we've memorized the transitions as children.)

<comment><USER5> You're doing all the work of dividing by 7. There are shortcuts to checking divisibility [1] - 2, 3, 5, & 9 have the easiest shortcuts - but 7 is a complicated case, which I'd probably just divide out anyway.

[1] [http://en.wikipedia.org/wiki/Divisibility_rule#Divisibility_...](http://en.wikipedia.org/wiki/Divisibility_rule#Divisibility_by_7)

<comment><USER3> No, he's not doing the work of dividing by seven. That would need memory of around the same size as your number of digits of your input number. His state machine only reads one digit at a time and only needs to store a less-than- one-digit state.

My regular expression is a joke on the usual divisibility rules.

By the way, you can find your own divisibility rules. They are actually easy to find and prove, if you know a bit about cyclic groups / calculating with modulo. E.g. the rule for divisibility by F in hexadecimal is the same as the one for 9 in decimal.

Divisibility by 11 or 101 or 1001, or 9, 99, 999 is also really simple.

Did you add a question mark at the end to avoid the dup checker?

<comment><USER7> That Submission is more than a year old. As far as I know, the dup checker doesn't check back that far.

<comment><USER8> It does. I came across this article yesterday morning and attempted to submit it to HN, found that it was rejected for being a dupe.

Ultimately, I submitted it to reddit.com/r/compsci instead. I assume fogus picked up on it from there and hacked the HN dup detector by appending a '?' to the URL. Kind of annoying, really.

</comment></comment></comment><comment><USER9> It kind of reminds me of this blog post from a while back about Apple's CFArray implementation and how it switches data structure implementations at about 300,000 elements: <http://ridiculousfish.com/blog/archives/2005/12/23/array/>

Just a reminder that the simpler things seem, the more complex they can often get under the surface.

<comment><USER10> The regex is not complex, just the php implementation is.

I feel like any regex expression should give an error or at least a warning if is going to return a potentially incorrect answer.

<comment><USER11> Would absolutely expect an exception if my regex engine decided it couldn't handle an expression!

Just giving back a wrong result unless you tweak the php.ini file seems insane. Stuff like this is really what makes PHP deserve its bad rep...

(If you're an old subscriber, you'll be moved to the new version in the upcoming days/weeks. Don't fret, if you don't like the look of the new version you can still select the old-style look).

<comment><USER4> Matching keywords in title/url/text _or_ url body, e.g. match the content of the url. Bonus points for being to use regex and select which fields you'd like to match against.

</comment></comment><comment><USER33> A bit to the side: I don't subscribe to any lists at the moment. Should I start? Is it better than just checking the sites I care about once in a while? How do you personally use it?

<comment><USER34> I used to consume most of my stuff through RSS but RSS seems largely dead unfortunately. It provides me with a nice balance between tracking (lots of) things but being able to pull that in when needed and keep it separate from other mediums like email. Subscribing to mailing lists usually ends up to me adding filters that move them to a different folder that I check less.

So for me, I subscribe to 3 or so newsletters. If I find myself not reading one weekly or monthly when it comes, I unsubscribe since it's not something I'm currently interested in. This avoids me ignoring mailing lists or newsletters in general so those that I do read actually add value. HN I check on a daily basis, it's a tab in my browser. But that's about it.

<comment><USER35> > I used to consume most of my stuff through RSS but RSS seems largely dead > unfortunately.

Why do you say this? I start my day with my RSS reader and the only site I follow that doesn't really support RSS is HN.

I tend to let my eyes slip over posts on here and Reddit concerning the topics I follow because they invariably end up in those newsletters. I got back and search them on here later if I feel like I need the Hacker News comments for further discussion.

Take a look at both of them; they might be exactly what you need to stay up to date.

For most major non-open-source software projects, there is an _unofficial_ users' mailing list. This is usually much more useful than the official support forum. Try finding it.

</comment></comment><comment><USER85> One that I've subscribed to for a very long time is "The Scout Report". Weekly set of 20 or so links to eclectic liberal arts things, but would appeal to a proportion of the folks here. ([https://scout.wisc.edu/about](https://scout.wisc.edu/about))

They are infrequent enough (a couple daily) to be OK in my mailbox, and are very good way to supplement news I'm consuming.

</comment><comment><USER93> Software Lead Weekly is consistently full of useful and interesting articles: [http://softwareleadweekly.com/](http://softwareleadweekly.com/)

</comment><comment><USER94> related but off-topic: Would it be nice if we could just go meta and share newsletters as "self-updating" bookmarks on something like pinboard(just a happy user here)? Next step - implementing machine-learning so that we have consistent static types. Tags are great but after a while I feel users forget them after a while and personally its a cognitive load on my side to make data structures of tags in my head. The second layer could be personal tags so that we have a more dynamic view. Is there something like this?

<comment><USER95> yeah, RSS.

Predicting Crime Using Twitter and Kernel Density Estimation [pdf] - <AUTHOR> http://ptl.sys.virginia.edu/ptl/sites/default/files/manuscript_gerber.pdf <comment><USER2> Interesting, but would this do any better than using real crime data, such as geolocated data police departments have already?

<comment><USER3> Even if it did worse, it could still be useful. It's common in statistical modeling that a bad model can be combined with a good model to make an even better model, and a whole ensemble of bad models can be a good model. As long as they are drawing on different data sources or are interpreting the data differently, their errors will not be exactly the same, and so they can be combined to get better results. In this case, Twitter seems like a rather different set of data than the historical crime records police departments presumably are using, and so it might be useful.

<comment><USER4> That concept is similar to the whole "wisdom of the crowd" thing, isn't it? Interesting.

<comment><USER3> Yes, wisdom-of-the-crowds or Condorcet's jury theorem are very similar.

(Now that I think about it more, there's also a lot of potential advantages to Twitter: global coverage, uniform data access, less risk of 'juking the numbers', less criteria drift over time... Yes, maybe local police records are much better, but you could spend a lifetime trying to get copies of them and putting them into the same data format and reconciling differing definitions etc.)

</comment></comment></comment></comment><comment><USER5> Wouldn't most of the information pulled just be news stations tweeting reports of crime though?

</comment><comment><USER6> Wonder how their system would deal with #SandyLootCrew</comment>


Hulu now longer claims to be "sold out" of online ad inventory - <AUTHOR> http://mediamemo.allthingsd.com/20081216/hulu-has-fewer-eyeballs-advertisers/

<comment><USER2> I'm so tired of users who routinely submit links to every single article they write- whether on topic or not- in order to generate ad revenue. Yesterday this user posted a link to some lame article about a cop punching a guy in the face. How about submitting a couple of your favorites that actually might be relevant here? If we like your stuff maybe we'll subscribe to your RSS feed or something. We don't need this site junked up with submissions of every single article from whatever sites a hundred different users are trying to plug.

<comment><AUTHOR> "How about submitting a couple of your favorites that actually might be relevant here? " That's what I'm trying to do - and I'm pretty sure that's most of the publishers/writers/bloggers who post here are trying to do. If were submitting everything we posted, there would be many, many more submissions. In any case, sometimes the HN folks like the stuff I submit, and sometimes they don't. I think that works pretty well, no?

TensorFlow JS: WebGL-Accelerated ML in the Browser - <AUTHOR> https://js.tensorflow.org/ <comment><USER2> Is there an active project that adds TensorFlow bindings to Node. I've found a few, but the latest commit on any of these is 5 months ago.

"Propel runs both in the browser and natively from Node. In both environments Propel is able to use GPU hardware for computations. In the browser it utilizes WebGL through deeplearn.js and on Node it uses TensorFlow's C API."

<comment><USER2> Thanks a lot for this. I just visited [https://deeplearnjs.org](https://deeplearnjs.org) and read that "deeplearn.js has become TensorFlow.js", so I guess that just about brings everything full circle :).

</comment></comment></comment><comment><USER3> Formerly deeplearn.js ([https://deeplearnjs.org/](https://deeplearnjs.org/)). For those who were following deeplearn.js, from the TensorFlow.js FAQ:

> "What is the difference between TensorFlow.js and deeplearn.js?"

> TensorFlow.js is an ecosystem of JavaScript tools for machine learning that > evolved from deeplearn.js. deeplearn.js is now called TensorFlow.js Core. > TensorFlow.js also includes a Layers API—a higher level library for building > machine learning models—as well as tools for automatically porting > TensorFlow SavedModels and Keras HDF5 models.

Github repo has been redirected. Nikhil Thorat (nsthorat) and Daniel Smilkov (dsmilkov) look to still be leading. Formal announcement expected at 10:30am PST at the TensorFlow Dev Summit (livestream: [https://www.youtube.com/watch?v=gplTc2F5Wvk](https://www.youtube.com/watch?v=gplTc2F5Wvk))</comment>


Life May Have Once Existed on the Moon - <AUTHOR> https://www.popularmechanics.com/space/moon-mars/a22539783/life-may-have-once-existed-moon/ <comment><USER2> It's nice to imagine the hypothesis. How can we validate, since we can't prove there was never life on the moon (can't prove a negative)?

<comment><USER3> Down here we'd do it with geology, up there it will be done with selenology.</comment></comment>

Ford is bringing all-electric F150 pickup to market 'before 2022' - <AUTHOR> https://electrek.co/2019/09/02/fordl-electric-f150-market-2022/ <comment><AUTHOR> What are the odds they will stick to their own timeline, or slip to bring it to market like everyone else.

I'm super curious if their investment also contained a deal to borrow some battery tech from Rivian.</comment>


Don't Blame H-1B Workers for Woes - <AUTHOR> http://www.businessweek.com/technology/content/feb2009/tc2009029_333899.htm <comment><USER2> The argument that H1-B workers are bad for America is, IMO, completely irrational. Whoever is in support of this argument is implying that people who are smart enough to get jobs in some of the top corporations[1] in America, or have made it to one of the top American universites, are _bad_ for the country. I'll repeat that for effect: _smart people are bad for America_. WTF?

Let's look at the situation from my POV, just for laughs.

I'm an Indian. I've been playing with technology since I was 13. I've spent hundereds of hours of my life learning how to program and cooking up small scripts and apps for simple tasks. I've spent sleepless nights trying to get a Linux install working. I've ignored school, college and exams because I wanted to be the first one to solve some programming puzzle online. Why? Because I'm passionate about programming. I want get a job doing smart stuff for a smart employer[2], and I don't expect to get that job in India.

The argument that immigrants are hurting America implies that America should just show the finger to me and give that smart job to someone who doesn't really enjoy doing it[3] _just because that guy was born in America and I was born in India_.

"" Enjoy having your standard of living averaged with the Third World. ""

Reading that statement just makes me sad.

[1] : I mean a _really_ good job at, say, Google. Nobody leaves India thinking, "I'm going to found a Web 2.0 startup in America.".

[2] : ... or start up a company. Not sure about how friendly India is to startups compared to America. There have certainly been many tech startups sprouting up in India in the past few years, but what they had to do to get where they are is still unclear.

[3] : This is not to imply that Americans are stupid. This is just a hypothetical situation.

<comment><USER3> Responding to your footnote [2], it would be interesting to hear what obstacles are in the way of doing a start-up in India. Are they the kind of things that can be worked around once and then the effort amortized over multiple start-up companies? If so, maybe there is an opportunity for something like YC in India that guides early stage people through the hoops required to start their own companies.

<comment><USER4> They are YC clones coming up all over here. Some of them invest, some dont. But none of them have anybody's of PG's stature behind them. So dunno whether any of them will ever succeed.

IMHO, incubators are a bit too early for the Indian ecosystem. Is very immature right now. Especially for first time entrepreneurs. Severe lack of talent and mentorship, angels are few and far between, Series A or further rounds, if you make it that far, happen at low valuations and successful exits are very rare. Add to that the very low internet penetration rate here. So focusing on the Indian market is a non starter. If you are targeting the global market, then its best to take advantage of the valley ecosystem. Eventually you'll have to have an office there if you want to succeed.

</comment></comment></comment><comment><USER5> It's understandable (if misguided) that people think that turning away foreign workers will help matters significantly in this country, but it's definitely not the answer. America does need to make sure that any foreign workers being brought into the country are being paid prevailing wages, and are not being used to help cut costs.

Of course, since I'm an American working overseas, I suppose it would be a bit hypocritical of me to support further limits on foreigners working in the States! I would like to see agreements between the U.S., Canada, and the EU to help make it easier for their respective citizens to work in other countries (obviously the EU has already done this within their member states). --That would provide more options to Americans as well as to others.

</comment><comment><USER6> The U.S. like any country, needs to look for ways of attracting talent. Sadly, migrating to the U.S. is very hard and it can take many years. I know people who have been waiting for more than 10 years. You cannot make any life plans with that type of waiting.

</comment><comment><USER7> I am for the elimination of H-1B visas only if it means an even more lenient immigration policy.

Free trade means the free movement of capital AND labor.

<comment><USER8> Enjoy having your standard of living averaged with the Third World. The best remedy for Libertarianism is experiencing the consequences personally.

<comment><USER9> Canada and Australia have pretty open immigration policies and their standard of living is higher than in the US.

<comment><USER8> How many Canadian or Australian H1Bs have you met?

<comment><USER10> My parents were both immigrants who came to Canada on "skilled labour immigration" policies. We enjoy pay that's well above the Canadian average (read: we're not working for pennies), and within my family we have 2 masters degrees, 3 undergrads, and 1 soon-to-be PhD.

Overall I think we have contributed to raising the Canadian standard of living, instead of detracting from it, and I wish that the US has the foresight to implement these policies - as a startup-minded individual I'd rather be there than here.

</comment></comment></comment></comment></comment><comment><USER11> What do you guys think of using patent applications as a measure of innovation? This seems common among researchers, and I can see why - it's easy to measure patents, whereas it's hard to track non-patented types of innovation (such as contributions to open source). But is this a case of looking for your keys under the lamp post because that's where the light is brightest?

<comment><USER12> I don't think that patents are a particularly good proxy for innovation - I've never even tried to get patents for a lot of the most cutting-edge stuff I've worked on (that would, in my lay opinion, be worthy of being granted a patent). And we all know the anecdotes of companies that patent every trivial modification they implement on standard algorithms or data structures.

On the other hand, I do know at least one scientist who checks out all the patents granted to a competing lab to keep tabs on the sort of research they do. He claims that, in our field, patents are a far better indicator of the amount of effort a lab is expending on a topic than papers published or press releases put out. _shrugs_

</comment></comment><comment><USER13> Alternate explanation, which would refute the thesis of this article: H1-B workers are disproportionately likely to work for companies with aggressive IP processes, like IBM and Microsoft, because those companies are also aggressive about recruiting H1-B workers.

<comment> old-gregg I believe most of those are patents filed by US graduate/PhD students of foreign origin working for big corporations either via H1b or using their student visas. These are the individuals we want to keep.

The "dark side" of H1b program is various ethnic sweatshops often filled with mediocre talent unable to find work anywhere else. I have known a person in Boston area who, along with 4 roommates, lived in his "owners" (H1b sponsor) basement where they were looking for contracts for themselves, so the sponsor could sell them later for a percentage. This crowd doesn't file patents.

Another, less evil "H1b business" is what many 3rd grade no-name universities do: they bring people from all over the world using student visas, give them loans, put them through 6-8 month Java crash-course, after which students are supposed to find themselves H1b employment. When they do, they have to pay $10-30K to their "school" while completing their "education" online (the requirement that lets these institutions maintain their legal university status).

I suspect that these shady H1b sponsors take up as much as half of all H1b visas issued to programmers year after year. As I said, big companies rarely bring people from overseas, they like to hire the best foreign graduates from good schools instead, where H1b works as a temporary bridge between a student visa and a green card, and that was the original idea behind it, IIRC.

</comment></comment><comment><USER14> "Kerr and Lincoln built algorithms that recognize likely foreign names on U.S. patent applications."

This doesn't seem very definitive to me.

<comment><USER15> Aside from that one patent filed by Crazy Horse, it came up 100%. Crazy.

</comment></comment><comment><USER16> What beats me is why so many Americans are against the H1B while barely anyone bats an eyelid at the Diversity Visas.

I assume it would make more sense for the US to cut down randomly allotted Diversity Visas and lift the bar on H1B . Or perhaps put in place the friendlier High-skilled Immigration policies. Wouldn't it be more beneficial to bring in an expert than some Tom, Dick, and Harry.

</comment><comment><USER17> I don't think this is a matter of numbers, but about what America would like for its future. A trip to Ellis Island may help remind the bases of a nation built upon immigration.

</comment><comment><USER18> Most of the H1B workers have colluded with sponsoring companies and the clients. And H1B workers are not creating new jobs in America.</comment>
