Calling Python Functions from Java (Without Jython, because it is too slow.) -

-
i need able call python functions java, , return of functions, should primitives only. i don't need access java objects in python or other stuff that. but, of all, need speed. need able load script @ start of application , call functions @ different time-intervals, can tiny (30-40 times per second). that's main-reason why don't think jython work me: has kinds of stuff don't need, , incredibly slow. so, constraints/requirements have: needs fast i need call python functions , result the script should loaded once do guys know way call python functions in pre-loaded script (so script not have loaded again , again each function call)? (ps: not think duplicate searched quite lot , links found did not answer question (for example calling python in java? ) ) you write jni code embed cpython interpreter. you write python program run daemon (or web service or whatever) , connect via sort of networking. intentionally vague here since such broad question

C strcpy and strcat -

-
i have question strcpy , strcat. in program i'm trying make need year born fiscal code. fiscal code given char serial port, strcpy(temp, code[6]); strcat(temp, code[7]); yyyy = 1900 + (atoi(temp)); this came with: last 2 digits of year added 1900 (i know doesn't quite work people born in 2000). first digit copied full code temp variable using strcpy, add second digit use atoi , convert eveything integer; use strcat in way i've never seen before. doing right? no need strcpy / strcat (and not appropriate in context anyway). no need temporary string either. can this: yyyy = 1900 + (code[6] - '0') * 10 + (code[7] - '0'); this extracts 2 digit characters, converts each 1 integer in range 0..9, , calculates year these 2 values.

i have been looking through similar posts , through imagemagick page, cannot seem find reason issue: note using windows machine. i have .ps image in folder , works when running command convert cmd: convert saved.ps newsaved.png however when try execute python script following code: args = ["convert","saved.ps newsave.png"] subprocess.popen(args) #or call(args) os.system("start newsave.png") the cmd window says newsave.png invalid parameter. (the error message being: invalid parameter - newsave.png in cmd window, closes instantly) having seperated comma in args has not helped. os.getcwd() returns current work directory well, know i'm in right dir. error happens when subprocess called. make each command-line argument separate element of args . also, use subprocess.call ensure convert function has completed before call os.system("start newsave.png") : args = ["convert", "saved.ps", "

sms - Can you send rich text messages via Twilio? -

i trying send rich text message via twilio. able send regular sms messages, want include hyperlink in body of text. i tried twilio mediaurl include rtf file, didn't work. including html in body of message doesn't work sends in plain text. i'm posting via curl twilio endpoints, i'd prefer not have php or other language achieve this. want send raw data twilio , receive rich text message back, if it's possible. twilio developer evangelist here. using twilio can send mms messages numbers in , canada. when pass mediaurl file needs hosted somewhere publicly on web , included within message. you can pass files of of mime types listed here , though when sending rtf result depend on how receiving device supports rtf files. if want include link, i'd recommend shortening url (using bit.ly or similar) , sending part of text. smart phones auto link url. built in sms apps on phones don't support markup of sort, why attempt html showed raw markup.

i play audio via javascript in following way: this.audio = new audio(); this.audio.src = "path/to/audio.wav"; this.audio.play(); the file audio.wav on server larger time , audio keep playing without interruptions. however, stop playing once reached point of initial file size. what can make play seamlessly? i pretty sure depends lot on server configuration. wave format (in pretty of flavors, including microsoft , riff) has field data size on top of data block. read audio element if preload attribute set blank, auto or metadata thus, web browser making request such file might request many bytes , close connection. there's nothing in the api description says it'll read until actual end of file met. one thing comes mind, though, registering on "end" event. then, according this answer , should able start playing again, seeking position you've ended on. server should start streaming data position need. if doesn't work directly
