math - exponential gauge calculation in JavaScript -

Image
i have little javascript ajax script gets speed on progress in kbps or whatever - let's mb/s. , want add gauge shows speed graphically. i have image containing gauge design , pointer. pointer default points @ top - lowest value -120deg , highest 120deg. wouldn't nice if has 1mb connection, need add exponential calculation. here values... 0-1mb: -120deg -> -90deg 1-5mb: -90deg -> -60deg 5-10mb: -60deg -> -30deg 10-20mb: -30deg -> 0deg 20-30mb: 0deg -> 30deg 30-50mb: 30deg -> 60deg 50-75mb: 60deg -> 90deg 75-100mb: 90deg -> 120deg i totally don't know how start calculation. the animation done css -webkit-transform:rotate(xdeg) and update on xhr.onprogress the calculation speed is: kb/s=((e.loaded/((new date()-start)/1000))/1024).tofixed(2), mb/s=(d/1024*8).tofixed(2) when have mb/s want set gauge deg. how can achieve these values? here not-completely-working variant. wrote while think it's not proper way. &

math - why we get only one unique straight line in a,b co ordinates for a point given in x,y co-ordinates? -

if there point given in x,y co-ordinate, can pass infinite number of straight lines varying slope , intercept b. when fix our x , y , vary our , b in a,b co-ordinate single unique line. why? found annoying while studying hough transform. i don't understand want ask....but yes may clear things bit. when fix point can make infinite lines pass through it.this obvious. fix a,b co-ordinates have fixed 1 particular case slope , y-intercept both. now note slope can vary between definite range. if consider argument, vary 0 degrees 180 degrees. out of infinite lines having different slopes pass through point (in case point on y-axis i.e. y-intercept of line) selecting 1 line in particular having specific slope. 1 such line possible. i hope answers question...

actor - Can I avoid cache consistency checks by declaring variables as thread-local? -

i'm reading how cpus maintain consistency of caches in multithreaded application. write in 1 core's cache labels dirty , other cores must careful not read segment main memory, because main memory copy not date. many of applications write work like actor system, mutability limited local variables on single thread. don't label them "thread local" unless have semantics reason doing so. however, missing optimization opportunity? explicitly labeling variable thread local, opposed using way, inform hardware doesn't have check consistency because variable never visible other threads, in principle? edit: higher-level way of expressing same thing, should expect performance gains using formal actor system, akka, instead of adhering actor paradigm in classes? formal actor system adds strictness, ability scale across computers, , presumably overhead, low-level details letting threads skip consistency checks on cached data known non-shared? does labeling data

tmux jump 5 lines in history / copy mode -

in ~/.tmux.conf have works great: bind-key -t vi-copy n cursor-down it allows me move cursor in history / copy mode. i want jump more rapidly (like in vim). i want jump 5 lines, doesn't work : bind-key -t vi-copy e 5 cursor-up how can add keybinding jump several lines? originally, tmux has restricted support commands in copy-mode. can't assign multiple commands, can't repeat them. option assign single command keystroke. however, there's mod tmux allows full-fledged support scripting in tmux: http://ershov.github.io/tmux/ (i'm author) using mod, can way: bind-key -t vi-copy k tcl { {set 0} {$i < 5} {incr i} { cursor-up } } also, you'd able use variables, loops, define own procedures , have more control on tmux internals.

Defining a class member that has required constructor arguments in C++ -

suppose have class foo constructor has required argument. , further suppose i'd define class bar has member object of type foo : class foo { private: int x; public: foo(int x) : x(x) {}; }; class bar { private: foo f(5); }; compiling give errors (in exact case, g++ gives " error: expected identifier before numeric constant "). one, foo f(5); looks function definition compiler, want f instance of foo initialized value 5. solve issue using pointers: class foo { private: int x; public: foo(int x) : x(x) {}; }; class bar { private: foo* f; public: bar() { f = new foo(5); } }; but there way around using pointers? if have c++11 support, can initialize f @ point of declaration, not round parentheses () : class bar { private: foo f{5}; // note curly braces }; otherwise, need use bar 's constructor initialization list. class bar { public: bar() : f(5) {} private: foo f; };

recursion - C: Finding Huffman-coded path of specific leaf in tree -

i'm trying write recursive function locates specific leaf within huffman tree, prints shortest path zeros , ones (zero being traversal left, , 1 being traversal right). understand logic of need do, i'm not having success @ implementing it. believe have skeleton here, part i'm missing more complicated logic tell when should run printf , when should not (since prints every 0 , one). also, know rest of logic outside of working because if normal traversal not have plot shortest paths, each of elements searching found. i've tried looking @ quite few resources online , cannot find solution, or @ least, cannot recognize solution properly. i've rewritten 50 or more times. let me know think! void traverse(struct tree *curr, struct tree *cmp) { if (curr == null) { return; } if (getleft(curr) == null && getright(curr) == null) { if (curr == cmp) { return; } } if (getleft(curr) != null) { printf("0");

css - In LESS, is it possible to import one selector's content into another one? -
