i'm tasked validating gtin-14, gtin-13, gtin-12, gtin-8 , upc-e barcodes. have seen few functions here , there, i'm unclear on how validate code without knowing ahead of time standard in use. i assume must possible, i'm @ loss should begin. validating content of barcode shouldn't problem. take @ specification different gtin-formats. problematic part check existence of required gs1 symbol identifier. commonly used libs barcode decoding (zxing, zbar) not give symbol identifier. exception zxing code-128. if have check other carrier types have commercial decoders. take @ question more details.

in app have receive , process data device, connected through com port. partially. in particular device first 2 bytes length of packet (minus 2 since doesn't take account these 2 bytes; length of rest of packet after all). then, since know device tends send me data slowly, read rest of packet in loop, until data has been read. right here encountered strange problem. let's assume entire packet (including these first 2 bytes length) looks this: ['a', 'b', 'c', 'd', 'e']. when read first 2 bytes ('a' , 'b'), i'd expect rest of packet this: ['c', 'd', 'e']. instead, looks this: ['b', 'c', 'd', 'e']. how come second byte of response still in read buffer? , why second one, without previous one? the code below shows how handle communication process: //the data array array output data //the size array two-byte array store frame-length bytes //the results array devi...

when list sliced, references contents copied original list? can imagine may not necessary, read opposite ( mentioned in passing ). this question matters instance following idiom, in case of long my_list : for (first_elmt, second_elmt) in itertools.izip(my_list[:-1], my_list[1:]): … a copy use both memory and, presumably, time. compared looping on index of first_elmt xrange() , on list of 100 million integers. slicing approach 20% faster, seem copy references (the system time longer). indeed case? ps : realize quite natural slices copy references: if original list modified, slice not change, easier have implementation of slice copy references of original list. pointer cpython implementation interesting, though. slicing copy references. if have list of 100 million things: l = [object() in xrange(100000000)] and make slice: l2 = l[:-1] l2 have own backing array of 99,999,999 pointers, rather sharing l 's array. however, objects pointers refer not cop...

while refreshing workbooks pivots (that externally linked excel file containing data) using vba ( .refreshall), dialog box titled "data link properties" pops up. i tried suppress dialog doevents delays, application.screenupdating=false, application.displayalerts=false, oledb.backgroundquery=false. nothing seems working. to make matters more confusing, dialog box doesn't pop regularly. does, doesn't. my debugging attempts has lead 1 theory: caused size of data file, , thereby memory excel taking in ram. dialog doesn't seem pop when both of these small. when file approaches more 10mb, dialog becomes more frequent. feel has memory, though there's @ least 1 gb of available memory. makes no sense i've run out of ideas. another clue: if click cancel on data link properties , click refreshall button on ribbon: gives "an unspecified error" , other errors related data file not being found, though path valid, , file exists. it refresh without...
