I read that as saying that Europe found out that they had to strengthen border controls to avoid ruin, not that they were already ruined.

It strikes me as ironic that you, as a relatively established member of HN, feel the need to resort to personal insults and general snarkiness in arguing that this article does not belong on HN. I agree with you on the quality of the articl

Would you advocate making a conviction necessary for a dns takedown, or letting defendants make their case before a warrant is issued? Your comment seems to imply that the latter is not the case at the moment; if so, do you have any idea wh

Yes, SEM is usefeul for analyzing circuits, but STM ( http://en.wikipedia.org/wiki/Scanning_tunneling_microscope ) is a completely different technique, which works at a scale about two orders of magnitude smaller. In a nutshell, SEM scans t

I find it suspicious that he mentions the use of scanning tunneling microscopy for analysis of circuit topologies. STM, as far as I know, is useful at the atomic level and would be complete overkill for analyzing ICs today, let alone ten ye

Keep in mind Moore's law as originally stated was a law of economics, not engineering -- that decreasing feature size means more dice and thus more revenue per wafer, while also increasing the performance of the individual ICs. These days I

heh, just got mine delivered today, and fired it up just to post this reply :-) It's a Toshiba AC 100 with an ARM-based Nvidia Tegra processor and Android operating system in a standard netbook form factor. I don't believe it's available in

I think the process by which they discovered their synthesis method qualifies as experimental physics. Keep in mind that it is still hugely infeasible to produce industrial quantities of the stuff. Also, as the parent says, a review of the

I was ready to be all sceptical too, but I actually came away from the site quite impressed. They seem to say that their wing tracing out the movement of the tip of a turbine, as well as operating at higher altitude will increase efficiency

I don't want to speak for the parent, but in my opinion, there is a clean separation between matter (ultimately consisting of atoms) and the information embodied in the arrangement of those atoms (eg in a book or DVD disk). In this scheme,

Could well be true, but it's not due to the free trade and immigration policies we're discussing here. The bureaucracy can mainly be traced back to the political institutions of the EU.

That's quite different from the way I understand it. You have to specify more exactly what you mean when you say the current price is $1.92. Is it the current best (highest) bid, best (lowest) offer, or last traded price (this is generally

My thoughts exactly. I remember a youtube video I saw recently in which a Lenovo sales guy tells the interviewer (at some trade show) that the software environment for their Skylight ARM-based netbook woulb be entirely proprietary, and that

Thought-provoking stuff.. While the intent of the fourth amendment is obvious and noble, I wonder whether, given the accelerating pace of creation and processing of information, it still makes sense to rely on legislation to prevent privacy

I agree on the influence of new technologies, but the current economic downturn has had nothing to do with that. The fact is that many people are unemployed now due to the eceonomy being as it is, and there seems to be a consensus that thin

Trees (plants in general) already do photosynthesis really well As I understand it, that's not exactly true; photosynthetic compounds are very efficient at harvesting light, but the chemical conversion to energy-carrying compunds is rathe

Not true, you may have been thrown off by the fact that s orbitals are generally shown as spheres; but the radial extent (probability amplitude) of the wave function goes to zero for small radii, for all s orbitals, see http://www.chem.uma

This is really excellent; exactly the app I have been looking for for the past year or so now. Only thing I could suggest improving is letting the pad take up more of my screen size.

I've struggled with this as well; the closest I've come to solving it was changing the keyboard layout preferences in gnome so that my right windows key now works as alt. I find that works almost as well.

This is interesting; reminds me of lisp in Haskell http://www.defmacro.org/ramblings/lisp-in-haskell.html Is there any practical use for these kind of projects? I imagine it might make make it easier to write multithreading programs when

I would say you have a harder chicken and egg problem than most social networking sites: Normally, the value of the site to a new user increases with the number of their friends use the site, because those are the people they interact with.

The whole point is that leveraging (i.e. investing with borrowed money) becomes much more feasible when interest rates are close to zero, as they were in the early years of the boom.

Thanks grellas for another insightful post; It's not the first time I've enjoyed reading your opinion a legal aspect of technology. In this case, I think it's interesting to note that the French may have gotten this idea into their heads to

About the gain: from the comments on other sites (I believe ars technica) I seem to remember this was indeed the case, but I can't be sure.. (I don't have access either from my holiday destination). As for real circuit fabrication, you are

What's the point, then? In traditional (solid-state-based) transistors, smaller dimensions has always meant faster switching speed, less energy waste and more efficient use of chip real estate. I fail to see how any of these are applicabl

I work in this field, and although it's nice to see some experimental progress being made, I am generally sceptical of the potential of such devices as transistors in the traditional sense. Firstly, the mantra that smaller is better is not
