  • Sorry, but this is completely wrong.

    Windows has ACLs and they are an important part of Windows administration, and used extensively for managing file permissions.

    Windows has supported ACLs on NTFS since Windows NT & NTFS were released in 1993 (possibly partly influenced by AIX ACLs in the late 80s).

    ACLs were not introduced to standard POSIX until c.1998, and NFS and Linux filesystems didn’t get them until 2003. In fact, the design of the NFSv4 ACL standard was heavily influenced by the design of NTFS/Windows ACL model – a specific decision by the designers to model it more like NTFS rather than AIX/POSIX.

    Technically, at the filesystem level, exFAT also provides support for ACLs, but I am not sure if any implementation actually makes use of this feature (not even Windows AFAIK, certainly not any desktop version).





  • Language is alive

    Where did I say it wasn’t? But language being alive doesn’t change history – the phrase was used by British writers before the USA even existed.

    and I can’t see anyone requesting origins specifically.

    So? I offered the origin as it was presented alongside a number of phrases that are of American origin, and that one stands out as not (also as being suspected far older in origin than the others). I’ve simply added some additional information to the discussion. If you find it “boring”, you are free to ignore it.

    I didn’t request your reply, yet you still wrote it.

    Phrases like this can be part of 2 cultures at once.

    Where did I say it couldn’t? I merely stated that the phrase was not of American origin. I didn’t say it wasn’t used in the US, or that the UK somehow has some special exclusive licence to it.

    and don’t even have hard proof one way or the other

    I didn’t post sources because I was short on time, but here, have some… (as I apparently now have time to waste…)

    • “Dogs and Cats rain’d in showre”, from the poem Upon a Cloke in Olor Iscanus (1651) by Henry Vaughan
    • “…and it shall raine… Dogs and Polecats”, from The City Wit, or, The Woman Wears the Breeches (1653) by Richard Brome
    • “it should rain Dogs and Cats”, from Don Juan Lamberto: or, a Comical History of the Late Times (1661) by Thomas Flatman
    • “Made it rain down dogs and cats”, from Cataplus, or Æneas, … (1672) by Maurice Atkins
    • “When it rains Dogs and Cats in Hell” from Maronides; or, Virgil Travesty, … (1678) by John Phillips
    • “raining cats and dogs”, from A Description of a City Shower (1710) by Jonathan Swift
    • “rain cats and dogs”, from Complete Collection of Genteel and Ingenious Conversation (1738) also by Jonathan Swift

    You will note that these are all British works by British authors. I can provide even more if you need them.

    While the ultimate origin is unknown (there are many theories), any claim to it being American in origin is surely nonsense. There is no evidence for this at all. If you have some, please provide it.

    What proof have you provided? Indeed, what has your comment added at all to the discussion? You could have looked up those sources and extensive etymological research on Google with less effort than you took to write your comment.

    Pretty boring…

    And what about your own comment? It adds absolutely zero additional information to the conversation, is rude, and you clearly misconstrued and misinterpreted my comment (apparently with the most negative interpretation possible), without even bothering to research anything for yourself.

    Personally, I think some may find it interesting that a phrase they might have thought was of modern American origin is actually from another country and of far more ancient origins they expect. To me, that is interesting. If it isn’t to you, why do you bother to read and comment?

    In the future, I suggest you simply ignore comments you find boring and move on instead of posting insulting low-effort replies.



  • “Raiining cats and dogs” is not of American origin. The precise origin is unknown, but the first recorded uses are British, dating from the early to mid 17th century (Earliest uses are raining “dogs and cats” and “dogs and polecats”.) although it’s possible the phrase is significantly older than this.

    The phrase is well known and widely used in the UK, and I doubt anyone here would consider it an American phrase.





  • Correct me if I’m wrong

    Well actually, yes, I’m sorry to have to tell you are wrong. Shannon-Fano coding is suboptimal for prefix codes and Huffman coding, while optimal for prefix-based coding, is not necessarily the most efficient compression method for any given data (and often isn’t).

    Huffman can be optimal given certain strict constraints, but those constraints don’t always occur in natural/real- world data.

    The best compression method (whether lossless or lossy) depends greatly on the nature of the data to be compressed. Patterns and biases can make certain methods much more efficient (or more practical) in some cases, when they might be useless elsewhere or in general. This is why data is often transformed before compression, using a reversible transformation that “encourages” certain desirable statistical characteristics in the data, so the compression method can better exploit them.

    For example, compression software (e.g. gzip) may perform a Burrows-Wheeler transform and other encodings before applying Huffman coding to get a better compression ratio. If Huffman coding was an optimal compression method for all possible data, this would be redundant! Often, E.g. in medical imaging, audio/video data, the data is best analysed in a different domain to better reveal the underlying patterns and redundancies in the data so they cam be easily exploited by compression. E.g. frequency domain instead of time/spatial domain.

    Damn, so what’s the name of the shape that’s a flat donut with an inner and outer circular perimeters? i.e. a filled circle with another smaller radius circular area subtracted from it. Or 2D cross section of a torus seen perpendicularly to the plane that intersects the widest part of the torus. A squished donut, or chubby circle, if you like.

    And many “circles” aren’t circles either, but 2D torus approximations. The edge of a true circle is made of infinitesimally small points so would be invisible when drawn. And even if you consider a filled circle, how could you be sure you aren’t looking at a 1-torus with an infinitessimally small hole? Or an approximation of all the set of all points within a circle?

    Clearly, circles are a scam.
