im trying fix scaling issue when our application prints on other papersizes a4. there existing method called getprintablearea, returns same values regardless of mediasize is: public size getprintablearea(pagemediasize mediasize) { _printqueue.currentjobsettings.currentprintticket.pagemediasize = mediasize; var capabilities = _printqueue.getprintcapabilities(_printqueue.currentjobsettings.currentprintticket); return new size(capabilities.pageimageablearea.extentwidth, capabilities.pageimageablearea.extentheight); } capabilities.pageimageablearea w/h set same values (761, 1090). , far can see selected printers imageable area a4 (in 1/96" units). how printers pageimageablearea other papersizes example a3?

algorithm - What is meant by uniform distribution of hash values in Hashing technique -

in hashing , uniform distribution of hash values mean. please explain in layman's terms using appropriate example. thank you it means if have size of hash-table (say n ), if hashing k values k<n , then: a sequence of outputs function must appear random sequence, if input numbers sequential also, fundamental thing hash function should minimize collisions obviously, @ same time, skewed input, output hash-function should distributed. edit: as asked, here uniform distribution means. say, if size of hash-table n , push k (<n) elements it, then, in every bucket of n/k in hash table, there should element. also, if k=r*c , in every bucket of size n/c in hash table, there should r elements. obviously, perfect uniform distribution not possible...but output distribution should not skewed.

compressing files in JAVA -

my project has requirement have receive file via rest service(using jersey) , store in database. the file size around 2-4mb. the received file can either zip or pdf format. before storing in database compress it. i googled , found there many available classes gzip, zip, deflater... thought of using deflater looked simple.i have written following code zipping. deflater deflater = new deflater(); deflater.setinput(data); bytearrayoutputstream outputstream = new bytearrayoutputstream(data.length); deflater.finish(); byte[] buffer = new byte[1024]; while (!deflater.finished()) { int count = deflater.deflate(buffer); outputstream.write(buffer, 0, count); } outputstream.close(); byte[] output = outputstream.tobytearray(); byte[] output = outputstream.tobytearray(); could 1 please suggest use case if use above code fine or have use other classes perform same. thanks, kitty bytearrayoutputstream caches compressed output in memory. have wrap around fileoutpu

scheduled tasks - Create job report across multiple java classes -

i implementing scheduled job needs create verbose report. report example this: date - started job date - looking stuff process date - got x stuff process date - processing y1 date - done date - processing y2 date - done date - processing y3 date - failed error : this_is_why_processing_failed date - processing completed date - job completed in z seconds the actual code doing processing can in multiple classes. obvious way implement have stringbuilder , pass around messages appended. another more advanced approach create singleton , have id somehow known across classes take part in processing (could thread name?), , store report string there. is there better way this? there best practices creating job reports? the job triggered using ejb timers. instead of passing around stringbuilder should use logger. singleton threadlocal member field place store "token" use classes working same job.

java - this.getClass().getClassLoader().getResourceAsStream()is not working in RCP product -

this.getclass().getclassloader().getresourceasstream(image_url) working when trying run rcp application eclipse. but, when running product, not running. this.getclass().getclassloader().getresourceasstream() returns `null´. clue how solve this? note: have tried solve using activator.getdefault().getbundle() . not working. seems activator.getdefault() = null means plugin not actiavted. tried put break point there. indeed plugin variable in null in activator. what should do? use filelocator : bundle bundle = frameworkutil.getbundle(getclass()); inputstream = filelocator.openstream(bundle, new path("relative path"), false); other methods of filelocator give url instead of stream.

python - Difference between list comprehension and generator comprehension with `yield` inside -

what difference between list comprehensions , generator comprehensions yield inside? both return generator object ( listcomp , genexpr respectively), upon full evaluation latter adds seem rather superfluous none s. >>> list([(yield a) in zip("abcde", itertools.cycle("12"))]) ['a', '1', 'b', '2', 'c', '1', 'd', '2', 'e', '1'] >>> list(((yield a) in zip("abcde", itertools.cycle("12")))) ['a', '1', none, 'b', '2', none, 'c', '1', none, 'd', '2', none, 'e', '1', none] how come? scientific explanation? the value of yield from expression none . fact second example generator expression means implicitly yielding iterator, yield value of yield from expression. see this more detailed answer.

c++ - Why can't I change address of a pointer of type `const int *` when passed as function argument? -

as far know, const int * implies can change pointer not data, int * const says can't change pointer address can change data, , const int * const states can't change of them. however, can't change address of pointer defined type const int * . here example code: void func(const int * pint) { static int int = 0; pint = &int; int++; } int wmain(int argc, wchar_t *argv[]) { int dummy = 0; const int * pint = &dummy; //const int * pint = nullptr; // gives error when try pass func(). std::cout << pint << '\t' << *pint << std::endl; std::cout << "-------------------" << std::endl; (int i=0; i<5; i++) { func(pint); // set pointer internal variable. (but, doesn't set it!) std::cout << pint << '\t' << *pint << std::endl; } return 0; } code output: 00d2f9c4 0 ------------------- 00d2f9c4
