Re: [go-nuts] How to convert time interval in days to human readable form?
If the only input you have is a number of days, as opposed to a start date and a finish date, it is not possible to convert it in years/months as the length of the years, as well as the length of the years, vary over time. Years can range from 365 to 366 days. Months can range from 28 to 31 days. As a side note, I am not sure this is strictly Go related. Have a nice day, Christian.

Re: [go-nuts] Panicking in public API ?
I'd suggest you expose both kind of APIs as in: * https://golang.org/pkg/regexp/#Compile * https://golang.org/pkg/regexp/#MustCompile Implementing the `Must` flavor is trivial, just call the standard func and panic() if you get an error. As a side effect you'll get a unique point where to panic(), and callers will recognize it's likely yo panic() because the function has "Must" in its name. If in doubt, implement only the func that returns the error, the other is just syntaxic sugar IMHO. Example: https://golang.org/src/regexp/regexp.go?s=10768:10804#L298 panics() have been, in my Golang experience, a pain to deal with. Most of the time they are just below a "TODO refactor that sh*t" comment, or they would deserve that comment anyway. Proper error handling takes time, but it's an investment that pays of. My 2c.

Re: [go-nuts] [?] emulating an opengl shader in cpu bound functions
Hi, Using OpenGL to draw something that will end up on paper might prove somewhat complicated. As for "translating" a shader to something cpu bound, since a shader is more or less a program in some language that "has some remote parentness with C", you could probably do it. But the most pragmatic way, IMHO, is to understand what the program does and rewrite it. If you really want to leverage OpenGL's power, I know it allows you to render "in memory" so you could draw things on a virtual screen, grab the output, and you're set. To some extent, recent OpenGL with shaders is more or less a generic way to harness the power of massive parallel, dedicated hardware, and it's very versatile. But complex as well. If you are not a graphics guru, I'd advice you to use a plain simple native Go library, there are several candidates, one is : https://github.com/llgcode/draw2d/ Have a nice day, Christian.
