Netcat is like a swiss army knife for geeks. It can be used for just about anything involving TCP or UDP. One of its most practical uses is to transfer files. Non *nix people usually don't have SSH setup, and it is much faster to transfer stuff with netcat then setup SSH. netcat is just a single executable, and works across all platforms (Windows,Mac OS X, Linux).
On the receiving (destination) terminal, run:
nc -l -p 1234 > out.file
You can use this class to realize a simple sectioned RecyclerView.Adapter
without changing your code.
The RecyclerView
should use a LinearLayoutManager
.
You can use this code also with the TwoWayView
with the ListLayoutManager
(https://github.com/lucasr/twoway-view)
This is a porting of the class SimpleSectionedListAdapter
provided by Google
Example:
When hosting our web applications, we often have one public IP
address (i.e., an IP address visible to the outside world)
using which we want to host multiple web apps. For example, one
may wants to host three different web apps respectively for
example1.com
, example2.com
, and example1.com/images
on
the same machine using a single IP address.
How can we do that? Well, the good news is Internet browsers
@implementation UIImage (scale) | |
/** | |
* Scales an image to fit within a bounds with a size governed by | |
* the passed size. Also keeps the aspect ratio. | |
* | |
* Switch MIN to MAX for aspect fill instead of fit. | |
* | |
* @param newSize the size of the bounds the image must fit within. | |
* @return a new scaled image. |
