javascript - Align objects with dynamic width in SVG -

-

i generating svg needs include dynamic text elements. general structure follows:

-------------------------------------------- |               <rect> <text> <rect> <text>| |                                          | |                                          | |                                          | --------------------------------------------

or bit clearer - it's legend @ top of chart:

enter image description here

the rectangles 5px 5px colored boxes, both text elements dynamic in width. 4 elements need aligned right.

is there way somehow 'float' 4 elements next each other. have looked @ far seems indicate each of these elements needs explicit x , y coordinate don't know until text rendered.

i'm aware there javascript options available ('getbbox()' etc) wondered if there using svg dom itself?

here's solution doesn't have javascript. uses font-awesome <tspan> draw entire text.

update: added "roboto" font , dy better alignment. 

<link href='http://fonts.googleapis.com/css?family=roboto' rel='stylesheet' type='text/css'> <link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css">  <svg viewbox="0 0 400 400" preserveaspectratio="xminymin meet" width="400px" height="400px" >   <text text-anchor="end" x="400" y="20">     <tspan dy="1" font-size="8pt" font-family="roboto" class="fa fa-fw" fill="skyblue"> &#xf0c8;</tspan>      <tspan dy="-2" font-size="8pt" font-family="roboto" >gross profit % &nbsp;&nbsp;</tspan>     <tspan dy="2" font-size="8pt" font-family="roboto" class="fa fa-fw" fill="green"> &#xf0c8;</tspan>      <tspan dy="-2" font-size="8pt" font-family="roboto" >op. profit % &nbsp;&nbsp;</tspan>     <tspan dy="2" font-size="8pt" font-family="roboto" class="fa fa-fw" fill="orange"> &#xf0c8;</tspan>      <tspan dy="-2" font-size="8pt" font-family="roboto" >net profit after tax % </tspan>   </text> </svg>

c# - Better 64-bit byte array hash -

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
