sorry in advance if repeat question. didn't see listed elsewhere. i'm trying find regex string recognize date of birth in format of mmddyy . far know though, regex doesn't know individual number sets begin/end if they're right next 1 another. is there simple way regex find (without requiring delimiters/spacing)? how like: ^([0-9]{2})([0-9]{2})([0-9]{2})$ the first group 2 digits month, next group 2 day, , last group year. if wanted smarter, make sure first group starts 0 or 1, , day should start 0, 1, 2 or 3. perhaps: ^([0-1][0-9])([0-3][\d])([\d]{2})$ you might not need use regex if don't want to. every single modern framework these days (python, .net, java, whatever) has libraries , methods parse dates in specified format. have added benefit of type checking , ability build native date object well. update: you use or verify day doesn't go on 31: ^([0-1][0-9])([0-2][\d]|[3][0-1])([\d]{2})$

i creating 2d rpg game in java , wondering how character movement can made smooth , not pixel pixel. i have animation thread runs every 20 mills , thats when draws everything. the simplest way of doing this, if you're saying movement calculated x = x + dx make x have higher resolution x axis of display. if x axis 640 pixels, make x have range 0 -> 5120 (640*8) example . when rendering downscale fit screen (add 4 , bit shift). that way can simulate having character move sub-pixel amounts per frame, results in smoother movement.

i have been using process.fork within observable object, have found interfering output observer object's file output. when comment out process lines, file output contains 16 lines each in order numbered 0-15. however, when uncommented file contains 136 lines of unordered numbers between 0-15. whether process commented out or not, correct numbers printed screen. is behaviour partially expected, or bug? has got ideas how around this? the code below reproduces problem , created stripping original code until there enough demonstrate issue. original reason using process.fork create several processes speed processing. require 'observer' class recorder def initialize(notifier, filename) notifier.add_observer(self) @save_file = file.open(filename, 'w') @i = 0 end def update puts @i @save_file.puts @i @i += 1 end def stop @save_file.close end end class notifier include observable def run 16.times

this question quite simple i'm not sure of terms involved answer myself. have mysql database containing of product information. make image appear on product pages products have attribute. have created sql query outputs list of product_ids products image show on. however, not know how use set of results in page itself. i have: $cupwinnerids = mysql_query("select product_id `jos_vm_product_type_1` jos_vm_product_type_1.cup_winner ='cup winners';"); while($row = mysql_fetch_array($cupwinnerids)) { echo $row['product_id'] . ","; } this outputs correct ids comma in between them. wrap whole thing $listofids = (...) , can use in product page php file: if $product_id in $listofids ... if not ... having problem understanding how use selection of ids. if try output list directly "array". appreciated. the problem may trying display array using echo, while should use print_r. in case this: $listofids = array(); $cup
