  • It’s good enough for NSA to catch a terrorist, not necessarily useful enough for FB to produce targeted ads.

    I disagree. Identifying a terrorist and their whereabouts for targeted assassination is not that different to serving personalized ads. It’s all about gathering information about the person.

    True, file metadata is unaccessible like message content but I was referring to message metadata which covers ip address and phone number (as you mentioned) but also geo location (possibly live - WhatsApp is an application after all), when you communicate with whom how often. You can derive lots of info from that especially if your communication partners are more careless about their data and may maintain an active social media profile with Meta.

    It’s definitely easier than finding out info about someone whose life depends on not being found - like a terrorist.





  • Ha, good one! Got me interested, how the standards bodies handle something like that. Found this in the Wikipedia article for byte:

    The unit symbol for the byte is specified in IEC 80000-13, IEEE 1541 and the Metric Interchange Format[10] as the upper-case character B.

    In the International System of Quantities (ISQ), B is the symbol of the bel, a unit of logarithmic power ratio named after Alexander Graham Bell, creating a conflict with the IEC specification. However, little danger of confusion exists, because the bel is a rarely used unit. It is used primarily in its decadic fraction, the decibel (dB), for signal strength and sound pressure level measurements, while a unit for one-tenth of a byte, the decibyte, and other fractions, are only used in derived units, such as transmission rates.

    Somewhat disappointing. “There’s a conflict but it’s fine”.


  • But there is also nothing contradictory or wrong with the unit MB.

    And I didn’t say that. Admittedly, the constraint “If the image size is defined as binary” probably could’ve been expressed better (I’m not a native speaker). File sizes are usually calculated in binary units (at least by Windows and the Linux distros I know - even though Windows continues to claim those are megabytes and Linux adopted the standardized units) and I’d bet that’s the case for file.coffee, too.

    Oh, well, I’m pretty sure we’re not really disagreeing anyway. So let’s conclude with the obligatory relevant xkcd.
