when create function, should have take argument seq , seqlike , genseq , or genseqlike ? (so many choices!) my requirements can map on , produce collection same number , order of arguments before. typically "program interfaces" , choose general type possible. in case, genseqlike . is correct/idiomatic? seqlike implementation layer seq allows specify return types. there extremely few things seqlike not seq , , arguably error. can feel comfortable not worrying -like s. (if want build new collections of type given , keep types straight, use canbuildfrom instead.) so question whether use genseq or seq . problem genseq processing might done in parallel, means have avoid using operation violate expectations (e.g. summing foreach ). furthermore, general consensus seems genx part of collections hierarchy overcomplicates collections , makes more difficult incorporate alternative choices of parallel collections. recommendation seq unless pretty sure

i've been researching ruby on rails , marketability today. how compare other programming languages (like java)? great time learn now? beneficial me learn primary programming language? i wanted know highs , lows technology before dive in , start learning. your opinions appreciated. the name of programming language ruby. ruby on rails awesome framework fast, efficient building of web applications. ruby interpreted language in opposition java or c#, compiled. ruby there's no need type definition or type casting, no semicolons @ end of line, no parentheses method invocations, operators overload, getters/setters automatically available instance variables , many, many more. (copied here ) i think learning curve ruby steep. but, after all, above opinion ... opinion. , you're question "would great time learn now?" answered pragmatic programmers: learn new programming language every year. so, why not starting learn ruby now?

i trying write handwriting recognization software, , need user input. can use imfreehand (with parameter, closed = 0) function let user write on top of blank plot axis. however, have 2 issues that: i cannot control thickness of lines i cannot convert scribble image i need 2, because, comparing handwriting training images stored in library. any idea on how on these or alternatives? thanks. to answer second question first, can use getframe . here minimal exemple: % --- free hand drawing imfreehand('closed', 0); % --- image axis off f = getframe; img = f.cdata; % --- display image figure imshow(img); then, answer first question regarding line thickness, it's little bit more tricky. have coordinates of curve, plot desired thickness , use getframe . it's little more complicated make clean respect application because of background color , axes scales, here try: clf xl = get(gca, 'xlim'); yl = get(gca, 'ylim'); h = imfreehand

i'm trying build car (wild thumper) can drive raspberry pi. i'm using raspberry pi on ssh. should send data arduino knows when has go forward or when turn. i've tried making scripts called jquery (apache on pi) , send integer on serial port requires delay , not ideal. (example forwardstart.py:) import serial ser = serial.serial('/dev/ttyacm0', 9600) ser.open() # here delay needed ser.write('4') # go forward ser.close() to solve tried looking single python script read keyboard , send correct integer. however, keylisteners require display , can't used on ssh. can me python script or idea works? thanks! you should start reading here . idea like import serial ser = serial.serial('/dev/ttyacm0', 9600) ser.open() # here delay needed try: while 1: try: key = sys.stdin.read(1) # wait user input actionkey = key2action(key) # translate key action ser.write(actionkey) # go forward
