问题 We have encountered a situation with Hg where no matter which way we merge two branches it wants to delete hundreds of files completely unexpectedly. i.e. merge branch A into B or B into A. More baffling no one has physically deleted them. Has anyone experienced this and can give guidance - this has become a major issue for us? Thanks. 回答1: Could there be a rename of a folder/directory involved? Perhaps one that's only a case change (ex: Stuff to stuff )? That could show up as a lot of

问题 I've developed a JavaScript Bookmarklet that have appended div to the current page. But problem is that, when div and its content loaded because of pages' original CSS codes (Bookmarklet has its own CSS as well), my div's appearance corrupts. I mean, on every page, some of elements looks different (sometimes labels' heights, sometimes textarea's backgroundcolor, etc.) Is there a way to correct this fault that you know? It can be a CSS or JavaScript solution. 回答1: Is there any way to correct

问题 I've always had this issue so I started creating a new single-view application, in Swift, for both iPhone and iPad. When the target is iOS 8.1 everything works fine, but if I set iOS 7.1 (or 7), i get a Segmentation fault. This happens when i go to Product > Archive, when i Run the project in the simulator or my device, everything is fine. I tried with both iOS 7 and 8 simulators and it compiles.

问题 So I've been developing this program for a while now... Its meant to act as an asset manager (and potentially more in the future) for our IT team. I have 2 services which we'll refer to as "Manager" and "IAM" for right now. The "Manager" does all things managerial for all services (currently only the inventory asset manager known as "IAM") such as automatic updates, etc., while the asset manager does its job. Anyways, its been working great for a while now. Recently I implemented an automatic
