• Compare two times without regard to Date associated - Ruby

  - by H55nick

  I am trying to find the difference in time (without days/years/months) of two different days. Example: #ruby >1.9 time1 = Time.now - 1.day time2 = Time.now #code to make changes #test: time1 == time2 # TRUE My solution: time1 = time1.strftime("%h:%m").to_time time2 = time2.strftime("%h:%m").to_time #test time1 == time2 #True #passes I was wondering if there was a better way of doing this? Maybe we could keep the Date the same as time1/time2?

• named anchors not working in safari

  - by David

  Hi there, can anyone explain why named anchor tags would not work in safari but work fine in other browsers: ie, ff, opera, chrome. I have some links to different areas of the same page and nothing happens when clicking on them in safari only. All the other browsers mentioned take me to that area of the page. I have tried using both the id and the name attribute for the anchors but neither makes any difference.

• In an iPhone app, is it beneficial to tile a background image that has a pattern in it?

  - by Dr Dork

  Here's an example of the type of background image I'm talking about, the iPhone Notes app... Clearly, there's a pattern in it. My question is, if this were an iPad app and the background image was twice the size, would there be any significant benefits to taking advantage of this pattern by tiling the image? Or would it really make no difference in terms of performance and just be easier to load the entire image into a UIImageView? Thanks in advance for all your wisdom!

• using makefile targets to set build options

  - by leo grrr

  This is either trivial or runs counter to the philosophy of how make should be used, but I'd like to have a command line that reads as "make debug" rather than "make DEBUG=1". I tried creating a phony target called debug that did nothing except set the DEBUG variable, but then there was a difference between "make debug build" and "make build debug"--namely that in one case, the variable got set after the build happened. Is there a way to give certain targets precedence? Thanks for your help.
