Can you supply arguments to the map(&:method) syntax in Ruby?
...
I like this solution, but I think you can have even more fun with it. Instead of defining a with method, define call. Then you can do things like a.map(&:+.(2)) since object.() uses the #call method. And while you're at it, you can write fun things like :+.(2).(3) #=> 5 -...

Does Java read integers in little endian or big endian?
...mats that use some form of Huffman encoding (i.e. all of them). For extra fun, JPEG is "bitwise big-endian" (i.e. the most significant bit is the "first" bit) and LZ is "bitwise little-endian". I once worked on a proprietary compression format that used both formats under the hood. Oh, that was f...

z = 1:10
)
One approach would be to group, and then only keep the first row:
df %>% group_by(x, y) %>% filter(row_nu...
