units-of-measurement

What are the advantages & disadvantages of each? em , px , % and pt ? My current choice are percentages, the only reason is because I can globally change the font-size of all elements, just by modifying the font size on the root element (body) I would recommend EM — simply because I use Baseline CSS for my basic set up of forms, layout and most importantly type. Can't recommend it enough : http://baselinecss.com/ My original design training said em's where possible. I believe a main reason was that different browsers and devices have different resolutions, which is once again becoming a big

I'm working on a game engine, and currently I'm stuck designing the IO system. I've made it so, the engine itself doesn't handle any file formats, but rather lets the user implement anything he wants by creating a *.dll file with appropriately named functions inside. While that itself wasn't much of a problem, my main concerns are the implications that'll probably be visible during the usage of the engine. I designed a simple resource interface as a base class for all the things the user can think of, and I'm trying to extend it by making simple child classes dedicated to the common data types

I have been trying to learn a bit more about delegates and lambdas while working on a small cooking project that involves temperature conversion as well as some cooking measurement conversions such as Imperial to Metric and I've been trying to think of a way to make an extensible Unit converter. Here is what I started with, along with code comments on what some of my plans were. I have no plan to use it like the below, I was just testing out some features of C# I don't know very well, I am also unsure how to take this further. Does anyone have any suggestions on how to create what I am talking

I need my application run in multiple screen resolutions. Currently I have specified all the dimensions in percentage (%) instead of pixels (px) so that it will automatically re-size with the screen. Which would be the more reliable unit of measurement for specifying dimensions on my webpage: Pixels (or EM) or Percentage For Responsive Webdesign you really should be leveraging media queries Personally I prefer pixels because they give me more control, and I can reliably know the exact dimensions of each element. With media queries you can also set new styles based on the screen resolution.

I would like to define a Measure type [<Measure>] type kB that converts to the number of bytes when explicitly cast to an int: (int)7<kB> // would result 1024kB - explicit would be fine Since there is no way to add an explicit conversion operator to a type like in C#, I am stuck. Anyone has an idea? Even better would be an implicit conversion , so that when a function requires numbers of bytes, it can be called like Allocate(7<kB>) // implicit would be superfine Special conversion functions do not appeal - writing a kB function is trivial but not as nice: let kB(n) = 1024 * n kB(7) 7 |> kB A
