Share VS File/NTFS permissions

  • Share permissions add up (you have permissions from multiple groups, so you get more permissions each).
  • Folder/NTFS permissions add up (you have permissions from multiple groups, so you get more permissions each).
  • BUT share and NTFS permissions added up together, actually limit down to the file permissions. E.g. you have read-write for the share, but only read from NTFS; subsequently you will only be able to read a file or folder, but not write to it.

Artifical Intelligence / Machine Learning: Generative Adversarial Networks (GANs) / Generative Modeling

Image
While there is a lot of buzz on data analysis and understanding data there for applied use of artifical intelligence and machine learning it is less known in the public on what Artifical Intelligence can do regarding generating original content and altering existing content. So called Generative Adversarial Networks can generate or change pictures and can even alter videos. E.g. The website www.ThisPersonDoesNotExist.com gives and interesting and somewhat worrisome examples of that technolgy. The speed at which this technology evolves is as astounding as the results it can give already. The technology can not only be used to generate static content like the pictures of faces, but can also modify videos. There is an example where the same scene filmed by day is recreated to appear at night: Another example illustrates how a video of a horse is transferred to a video of a zebra. As Ian Goodfellow points out the GAN did not only change the brown horse to be white with bla...

Dates in JSON

What format is the right one in JSON? "Or best? Is there any sort of standard on this?" "DateTimes in JSON are hard. The problem comes from the JSON spec itself: there is no literal syntax for dates in JSON. The spec has objects, arrays, strings, integers, and floats, but it defines no standard for what a date looks like." A common date/time-format used is ISO 8601. It is also used widely in libraries such as JavaScript's toJSON-method and Json.NET . In principle this turns the DateTime string into: <YYYY-MM-DD>T<HH:MM>[:SS.SSS][[+|-]HH:MM[:SS]|Z] Example: { "lastPlayedDateTime": "2021-12-28T23:30:00+01:00" } What's the Z? Z depicts the shorthand notation for UTC times, e.g. "2009-02-15T00:00Z" . Sources: Serializing Dates in JSON StackOverflow What is the "right" JSON date format?
