can explain behavior in clojure code below? don't it. clojure somehow replace or "optimize" function arguments? why calling function single nil argument result in arityexception ? (defn foo [bar] (reduce #(%1) bar)) (foo nil) -> arityexception wrong number of args (0) passed to: test$foo$fn clojure.lang.afn.throwarity (afn.java:437) see (doc reduce) : [...] if coll contains no items, f must accept no arguments well, , reduce returns result of calling f no arguments. [...] here coll nil , being treated collection containing no items (as in similar contexts), , f #(%1) . thus #(%1) being called no arguments , ends throwing exception see.

Binary image type in C -

if want create , work on binary image in c, data type should set image pixels? since binary image pixel has 2 values assuming need 1 bit each pixel , have use bit wise c functions, correct (most efficient) way binary image processing in c? if case, how can allocate space image? malloc allocates space in units of bytes if not mistaking. for clarification: have 32bit float image (with known size), apply threshold , save thresholding result binary can label separate components. using single bit per pixel memory-efficient least time-efficient, since accessing pixels requires bitwise operations. if wanted this, have malloc((numpixels + 7)/8) , i.e. round allocation size nearest byte. it better balance of memory , space considerations store image char s. internal representation thresholded images in opencv, example.

c++ - The usage of _InterlockedCompareExchange64 -
