i'm trying take collection of records in ember , split them groups of number, 2. so example, {{#each node in model}} <span>node.name</span> {{/each}} i <span>thing</span><span>other thing</span><span>some thing</span><span>one more thing</span> i want able pass node , wrap every 2 nodes div <div><span>thing</span><span>other thing</span></div><div><span>some thing</span><span>one more thing</span></div> in ember 2.0 should component, best place handle logic. should component or controller? given principle things related display, or preparations therefor, belong in component, prefer component. so: partitions: computedpartition('model', 2) then in template {{#each partition in partitions}} <div> {{#each node in partition}} {{node.name}} {{/each}} </div> {{/each}} now remains write com...

when key guessing, key length used in cipher determines practical feasibility of performing brute-force attack, longer keys exponentially more difficult crack shorter ones. cipher key length of n bits can broken in worst-case time proportional 2^n , average time of half that. average combination 2^n-1. why formula 2^n consist of 2? the key length measured in bits binary value. either 0 or 1, there's 2 different possible answers each position. a key length of 1 can either 0 or 1. 2 possible combinations. can represented 2^1. a key length of 2bits can 00, 01, 10, 11. 4 possible combinations, or 2^2. the 2 constant, it's number of bits change.

i'm looking through header files of library i'm using (i don't have implementation source files), , noticed there set of enums proceed (simplified): enum type { type1 = 0x0007, type2 = 0x000a, type3 = 0x000b, type4 = 0x000c, type5 = 0x000d, type6 = 0x000e, type7 = 0x000f, type8 = 0x0010, }; i'm familiar seeing 1,2,4,8... progression using enums bit flags, 7,10,11... kind of standard pattern? know there's not meaning values, seemed oddly specific since of values sequential. it isn't unusual see progression missing numbers. might used internally library, used other external component library interfaces, or reserved future development. to safe, use defined values.
