“unrecognized import path” with go get
...
Just installed fresh golang 1.3 on fedora 20 and go get gives the same error. GOROOT is set to /usr, go itself installed into /usr, not /usr/local. Set GOPATH to $HOME/go. Any idea what else to check ?

...ry.
I made a minimalist "hello world" that renders SVG to a cairo
surface and writes it to disk:
import cairo
import rsvg
img = cairo.ImageSurface(cairo.FORMAT_ARGB32, 640,480)
ctx = cairo.Context(img)

How to add a filter class in Spring Boot?
...
When I tried that approach, Filter was created as bean and even was injected to other class but init() method didn't run. Probably, init() works only in 'normal' registering not by spring container. I think, one may use PostConstruct instead of init() but I didn't try that as I r...
iOS 7 - Status bar overlaps the view
...In the storyboard, I moved my views 20 pixels down to look right on iOS 7 and in order to make it iOS 6 compatible, I changed Delta y to -20.

Best way to check if a URL is valid
.... But it can't read your mind. There's a huge difference between invalid and unwanted.. Unwanted is very subjective, which is why it's left to the programmer to work out that detail. You might also note the code validates the URL, but doesn't prove it exists. It's not PHP's fault that a user mi...

Why is there no logical xor in JavaScript?
...
JavaScript traces its ancestry back to C, and C does not have a logical XOR operator. Mainly because it's not useful. Bitwise XOR is extremely useful, but in all my years of programming I have never needed a logical XOR.
If you have two boolean variables you can mim...

Editor's Dis/claimer: FastMember is a Marc Gravell project. It's gold and full-on flies!
Yes, this is pretty much the exact opposite of this one; reflection would suffice - or if you need quicker, HyperDescriptor in 2.0, or maybe Expression in 3.5. Actually, HyperDescriptor should be more than...
UltiSnips and YouCompleteMe
I have bundles ultisnips and youcompleteme installed on my macvim.
The problem is that ultisnips doesn't work because tab is bound by ycm.
I tried putting let g:UltiSnipsExpandTrigger = "<s-tab>" so that I can trigger the snippet completion with shift-tab, but it doesn't work for some unknow...
