im using java edit text files containing records. files handled old systems probably use mazovia ( wiki ) encoding. cant find way handle files , it's beginning give me headache. when edit text files java code, systems find additional characters in them, breaking entire record structure (character position matters). how edit files without introducing additional characters/breaking encoding? proper display of characters great, if it's not possible, i'll make not breaking record structure. if use example iso-8859-1 when reading , writing not break file since every byte maps character , every character maps single byte. (any encoding these characteristics do.) you won't correct unicode characters when reading (for have implement custom charset , i'm not sure how work is), @ least won't break file.

i found color definition in xml file looks #8867d1fd . wanted check in e.g. photoshop color picker keeps cutting 2 last digits. kind of notation it? colors defined 6 digits (red , green , blue components of color) , 2 digits alpha degree of transparency. useful if want show content , background well. 0 alpha means transparent, ff means solid , background not shown. number in between means semi-transparent or semi-solid. so format is: argb ( alpha , red , green , blue ) to check color use #67d1fd check color without alpha.

this isn't specific problem, more theoretical question. there ever reason expose multiple global variables for single javascript application ? i can see using, , use myself, single global variable name object or class containing app can recalled multiple times (example below), can't think of case when additional global variables couldn't replaced object properties. example exposed variable makes life easier (using closure, couldn't recalled): var myglobalapp = { init: function (args) {...}, methodone: function () {...}, methodtwo: function () {...}, propertyone: 'string example' }; myglobalapp.init(arg1); myglobalapp.init(arg2); does know of instance case multiple global variables necessary? i don't think it's ever strictly necessary have multiple globals - javascript objects can arbitrarily nested, , can used namespaces. window.awesomemodule = { app: { ... }, util: { ... } }; in ...

i have made exercise on c#, here is: class program { static double funk(int a, ref int b) { double c = + b; = 5; b = * 3; return c; } static void main(string[] args) { int = 1, b = 2; console.writeline(funk(a, ref b)); console.writeline(a); console.writeline(b); console.readline(); } so, result pretty clear when run code, gives me: 3 1 15 my question is, did 15 , 3 came from? the 3 came from: double c = + b; //... return c; this gets printed out console via first writeline . the 15 comes from: double c = + b; // c == 3 = 5; b = * 3; // b == 5 * 3 == 15 since pass in b ref , you're changing actual value of caller variable ( b in main ), gets set 15, printed out third writeline .

i have method accepts int[] (userids) , int (groupid) parameters. runs stored procedure , insert data db for example: if userids=[1,2,3] , groupid=4, want following data inserted db userid groupid 1 4 2 4 3 4 i have 2 solutions problem. first 1 write stored procedure insert single record db. in method(), loop through int[] , call stored procedures n times method() (int =0; i< userid.length; i++){ // call stored procedure insert single record } the second solution pass int[] , int parameters stored procedures , looping in stored procedure. which way better solution? ( if 2nd solution better, can provide guidance on handling int[] in stored procedure ) is there reason why don't want use o/r mapper? example looks server / code-behind , can use entity framework (or other) insert new values. if can't use them use ( 2nd in posting) approach. it's dangerous, because not within transaction. you can start entit...

i working canada (fr-ca) locale , trying following: var str = "<dataset >{1}</dataset>"; var temp = "<set cost x = '1,8m $' />"; str = str.replace(/\{1\}/g, temp); output: "<dataset ><set cost x = '1,8m </dataset>" /></dataset>" desired output: "<dataset ><set cost x = '1,8m $'" /></dataset>" replace function misunderstanding $ ' '1,8m $' expression , hence repeating in output. ideas/workaround? thank time. $' has special meaning in replacement string when using js regular expressions: inserts portion of string follows matched substring. literal dollar sign in replacement string, use $$ . see https://developer.mozilla.org/en-us/docs/web/javascript/reference/global_objects/string/replace .

say go example.com/testing/1/2/3. don't want request directory "/testing/1/2/3", want pass part of url script (presumably example.com/index.php). i don't know if works described, reason ask because in wordpress, in "permalink settings", have option change url scheme http://example.com/2013/08/sample-post/ , when navigate url shows post. however, doesn't create of directories, or directories matter. i'm wondering how works because i'd use in other places. seems commonplace (i doubt url shorteners have hundreds of thousands of directories @ root of domain , use instead), i'm not sure called or how find more information , hoping point me in right direction. thanks.

os.urandom or ssl.rand_bytes : when generating random bytes cryptographic purposes, more recommended? if neither 1 better, tradeoffs , expected each in terms of differences? note ssl.rand_bytes exists in python 3. ssl.rand_bytes needs seeded before can used. cannot rely on ssl.rand_bytes alone. both os.urandom , `ssl.rand_bytes pseudo random number generators. prng's deterministic; when seeded same data, return same stream of pseudo random number bytes. these bytes should indistinguishable true random if observer not know seed value. os.urandom (re-)seeded using source of entropy within operating system. using os.urandom should therefore preferred on ssl.rand_bytes . first of all, seeded (and reseeded operating system). furthermore, not require additional dependency on ssl library. drawback performance. faster use ssl.rand_bytes seeded big enough value os.urandom os.urandom requires system call time retrieve data.

i have should problem simple solution, , i'm sure i'm missing something. i have 2 columns of radio buttons, , when radio button column clicked, need disable corresponding radio button opposite column, can't selected. if button selected, re-enable previous button , disable new opposite selection. i have given radio buttons unique id. first1, first2, etc. column one, , second1, second2 etc. column two. the way headed towards won't work after re-thinking this, , after searching online hour, haven't found non-jquery way of doing it. possible javascript? what had far, , know i'm way off base, i'm burnt out different problems i've had page: function disableform(theform, theradio) { //this start does't save valid disabled fields //it enables if (document.all || document.getelementbyid) { (i = 0; < theform.length; i++) { var formelement = theform.elements[i]; if (true) { formelement.dis...

i'd use 3 or 4 c# timers interval 40ms (to work image data 1000/25 = 40). according msdn seems pattern perform task every 40ms. default interval 100ms. in real life, i'd know if 40ms still ok ? or if should use thread design pattern ? wakeup/sleep behavior near cpu free ? there no special relevance 100 msec default, can change needed. you need pick values if want interval that's consistent 1 machine another. accuracy of timer class affected default operating system clock interrupt rate. on windows machines, interrupt occurs 64 times per second. equal 15.625 milliseconds. there machines have higher rate, go low 1 msec. side-effect of other programs changing interrupt rate. timebeginperiod() winapi function , has global effect. so best intervals pick ones multiple of 15.625 , stay below that. chosen interval repeats on machine. makes choices: 15 31 46 62 etc. your best bet aiming near 40 msec therefore 46. accurate 1.4% on machine. p...

i noticed inadvertently saved favicon png. , nothing bad happened. what gained saving .ico . way done ( i've looked @ many favicon links in other web-apps ), i'm trying understand @ deeper level. i'm saving @ 32px 32px. here boiler plate. <link id='file_icon' rel='icon' href = 'foo/foo.png'> compared to: <link id='file_icon' rel='icon' href = 'foo/foo.ico'> mainly because .gif , .png files don't work favicons in internet explorer. also, .ico format allows store customized versions @ different resolutions, i.e. 16x16, 32x32, 64x64 pixels, , various color depths (16, 24 or 32 bits), insuring best possible available icon, regardless of size or color depth available in browser. http://www.photoshopsupport.com/tutorials/jennifer/favicon.html

i'm trying understand if adapter pattern implementation dependent on interface realizations. read, should use adapter when need convert interface of class interface clients expect. i have been told classic example of 3 pronged plug using adapter connect 2 pronged plug... so, understand, if method in class has method specific paramater signature, , want wrap logic require more (or less) paramaters, should implement adapter pattern. from examples iv'e seen, proper way create adapter class realizes interface desired method signature, , hold adoptee member in adapter class. then, can call adpotee method through realized interface method , input logic. the question is, if need use 1 adoptee class, why use interface? not simpler drop interface bit , hold adoptee member , implement desired logic in "stand alone" method? is required realize interface method here adapter pattern valid? public class poststatusadapter { public interface ipoststatus { ...

i wondering if there more efficient method getting objects out of linkedhashmap timestamps greater specified time. i.e. better following: iterator<foo> = foo_map.values().iterator(); foo foo; while(it.hasnext()){ foo = it.next(); if(foo.get_timestamp() < minstamp) continue; break; } in implementation, each of objects has 3 values: "id," "timestamp," , "data." objects insterted in order of timestamps, when call iterator on set, ordered results (as required linked hashmap contract). map keyed object's id, can lookup them id. when them timestamp condition, however, iterator sorted results. improvement on generic hashmap, still need iterate sequentially on of range until find next entry higher timestamp specified one. since results sorted, there algorithm can pass iterator (or collection to), can search faster sequential? if went treemap alternative, offer overall speed advantages, or doi...
