    The same thing does happen with light, in that your simple first example does need to consider relativity if you want to be exceptionally precise. It’s not correct to suggest these two scenarios are fundamentally different, where only one needs lorenz corrections. In truth, both scenarios do, its just that the correction is so insignificantly small for the first example that it can be left out without any significant change in the answer.


  • Partially true. The difference is that in Linux, when you delete a file, you’re just removing the directory entry (potentially just one of many entries that point to the same data). The filesystem doesn’t actually remove the data and reclaim space until all open handles are closed and no remaining directory entries point to the data.

    Any running processes that have the file open are able to continue to read and write that data via the handle despite the directory entry being removed, until the handle is closed.











  • I said they may be right because we’ve not seen them take any other option. In other words, we lack the data to know if their ‘play it safe’ strategy is the one that results in the most votes, or not.

    Perhaps you and others are reading too much into my post and think that I was supporting the safe option. I was not, I was merely noting what they continue to do. Perhaps this explains why I initially got upvotes for a few days and then got downvoted below freezing?
