  1. In portuguese it's "chá", and came through se on Why the World Only Has Two Words For Tea (qz.com) · · Score: 2, Informative

    In Portuguese the word is "chá" and originated in Macau. That does not match the article theory: it came through sea trade, at least in that case.

  2. Re:Hippism? on IeSF Wants International Game Tournaments Segregated By Sex [Updated] · · Score: 2

    PS: Sorry, it's called "Equestrianism" in english, sorry :P

    None of the equestrian disciplines are segregated by sex as far as I know...

    Hippism is not segregated, as far as I know, and is an olympic sport...

  4. Just use Baidu or another search engine... on EU Court of Justice Paves Way For "Right To Be Forgotten" Online · · Score: 1

    Just use Baidu or Yandex or another search engine..., it's a multipartite world, choose your poison :)

    The decision is effectively unenforcable globally. For example, baidu is great for searching google-MPAA-censored content, etc.

  5. How to solve those issues once and for all on Why Facebook Is Stressing You Out · · Score: 2

    I solved those issues long ago by behaving in the same way for all social circles. I've set for myself what I think are acceptable and honorable behavior patterns and abide by them always. Take it, or just leave me alone, it's that simple. That includes my friends, co-workers, parents, and just about anyone I know. It means I have to restrict myself a bit, but it also means I'm essentially a better person.

    PS: yes, some persons don't like it, but they are a tiny minority.

  6. Not too many pixels in fact. on Nokia Puts 41MPixel Camera In a (Symbian) Phone · · Score: 5, Informative

    Actually since this is a near diffraction limited lens working at f/2.4 the spot size is going to be about 0.56um * 2.4 ~ 1.344um on the focal plane. The cycle size is about double, or 2.688um.

    Considering it uses a Bayer array, and the pixels are spaced at 1.4um, the green pixels will be spaced at 2um (minimum distance to next green pixel). To properly sample you need at least 2 pixels per cycle (said Mr. Nyquist), but since pixels are not exactly points (they have an area) astronomers working in diffraction limited imaging advise 3x sampling in practice.

    What this means is you would need a pixel size of 2.688/3/sqrt(2) ~ 0.63um (or 0.9um if using a Foven-style sensor) to properly sample this lens. 1.4um vastly undersamples the lens, as can be seen near the central area in the available samples: they are razor sharp in the central area, and otherwise are limited by aberrations.

    A practical article describing this, with example images, can be seen here:

  7. The specification may be buggy in itself... on World's First Formally-Proven OS Kernel · · Score: 1

    In the few programs I've made that had to be secure, by all means, bugs in the specification were found, years later, that allowed system compromise. Assumptions were made about other systems (that allowed us to authenticate users, validate user-classes, etc) that were false under some circumstances, for example, making a break-in possible even if the core itself was not buggy in itself. It would, essentially, maintain it's integrity but be fooled by others...

    This is just like in cryptography: a secure algorithm does not guarantee whole system security.

    Still a great achievement!

  8. They are religious because they don't accept death on Study Finds the Pious Fight Death Hardest · · Score: 1

    IMHO most persons are "religious" because they fear death to begin with and can't accept they are limited in space and time.

    Non religious (does not mean atheists) guys tend to accept their condition and see death as perfectly natural and nothing special. they learned to live with it as part of their non-reliousity.

  9. There is a better way.... on Cell Phones, Missing Persons, and Privacy · · Score: 1

    In my country at least (Portugal) the police will track anyone missing, but they can't legally tell anybody else where that person is unless the person allows them. Unless it's a minor, of course...

    The most they will tell the family by default is "we found it, and it's alive and well".

  10. Modify earth albedo instead? on A Sunshade In Space To Combat Global Warming · · Score: 1

    It would be way easier to modify earth's albedo instead.

    Man has modified albedo in two directions: polar caps are shrinking, decreasing albedo, and forest is shrinking also, increasing albedo.

    But by actively modifying the albedo of part of the sahara and the other big deserts, for example, you could feasibly dump into space the few percent required to equilibrate earth's climate.

    A combination of controled deforestation with desert "painting" could also do the trick.

    All this seems far more plausible than sun shades.

  11. Microsoft as the borg... on Microsoft Acquires Winternals and Sysinternals · · Score: 1, Insightful

    Yet another proof that Microsoft can't behave like a normal market player. They fear even those working for them. They feel the need to control everything under the sun.

  13. The english translation is junk... on EU Rapporteur Publishes Software Patent · · Score: 1

    While the original report written in french is quite nice in itself the translation resulted in a badly written, erroneous interpretation prone, report...

    Anyone wants to help the EP with translations? :D

    PS: I'm neither french nor english, so I'm not going to do it.

  14. OpenGL is prior art on Apple Files Patent for Translucent Windows · · Score: 1

    OpenGL supports the concept of translucent entities.

    Many OpenGL games, as well as DirectX, have used translucent windows (for configuration settings, etc) in the past.

    The alpha channel tecnique is exactly the same. I doubt this patent is enforcable. Perhaps SGI could patent this one?

  15. Performance is only one more factor on 2nd Multi-Format 128kbps Public Listening Test · · Score: 4, Insightful

    Yes... certainly this kind of listening test is important to access the capabilities of each codec.

    But in the real world other factors may be more important to chose a coded, like for example general acceptance, freely available code and specs, and a large content base available.

    You see: performance will increase allways in all codecs with time... so this kind of testing is only a minute factor amongst others.

  18. Re:Well, IANAP on Solar Sailing and Physics · · Score: 1

    That's false, since the photons get reflected in an accelarating and moving object relative to the emission frame, so in that frame hey are reflected with longer and longer wavelenght as the object accelarates away from the emission point.

  19. Re:When MS cuts prices.... on OSS Officially On Microsoft's Financial Radar Screen · · Score: 1

    I've just installed RH8.0 in my old i486DX-2 66MHz.

    Sure, it has 32MB (motherboard won't support more with the cache activated), and a 2.5GB disk (the original was 517MB), but it works just fine both as a router (IPv4 & IPv6) and web-server.

    I've also installed the development packages, etc... works just fine. Try that with XP :-)

  20. Weird russians... on Slashback: Bankruptcy, SUVdiving, Singalongs · · Score: 1

    I would have thought that any relatively powerfull state would have access to the windows source code if they really wanted. If needed they would resort to espionage, I presume.

    I doubt the russians didn't already had access to the code. It's kinda weird they are paying Microsoft to get this.

    I presume this is just an officialization :-)

  21. Re:radiation suits is a misnomer on Lightweight Radiation-proof Fabric? · · Score: 2

    Eletromagnetic radiation tends to reflect of any conductive surface, like a faraday cage.

    Faraday cages are effective if the radiation wavelength is bigger than the cage net. As you increase radiation energy the wavelenght gets smaller. You can still reflect it by decreasing the aparent net size as seen from the photon.

    That's why a X-ray telescope uses special mirrors that reflect radiation at shallow angles (1 or 2 degrees). Those pthtons see the atom lattice from shallow angle, therefore it looks smaller.

    Perhaps this kind of polymer has an high eletronic density as seen from most angles, therefore being effective against most low energy X-rays for example.

    I doubt it has any effect against hard X-rays, or gamma rays, witch are generally deflected by direct interaction with the nucleus charge, and not with the eletron clouds, but it could be effective against low energy X-rays (1-2 Kev or so).

    No, because Microsoft is a convicted monopoly, and therefore is (or will be) subjected to some restrictions concerning it's business model, meaning it will be a regulated monopoly.
