i trying make simple animation; on mouse over, button animate bigger. when not hovering, return it's original size. however, whenever when try sample code, warps button odd sizes $('.btn').hover(function() { $(this).removeclass('btn-primary').addclass('btn-warning'); $(this).stop().animate({ 'height': $(this).height() * 2, 'width': $(this).width() * 1.3 }, 300); }, function() { $(this).removeclass('btn-warning').addclass('btn-primary'); $(this).stop().animate({ height: $(this).height(), width: $(this).width() }, 300); }); http://jsfiddle.net/rblqy/1/ how problem solved? i'm not entirely sure why code failing, seems have sort of calculation error when returning original size. after fiddling around bit found solution. animating padding instead of height , width don't have worry height width ratio when comes resizing link. $('.btn').hov

i'm trying display small double value on textfield . example, docalculationforequalpressed function returns 0.00008, when display on text field shows exponential record (8e-05). don't need number shown in exponential view. how set precision when use exponential record ??? using specifier %.9g - doesn't help. double result; result = [self.brain docalculationforequalpressed:[self.brain operationarray]]; if (result == infinity || result == -infinity || isnan(result)){ nsstring *infinity = @"\u221e"; self.displayfield.text = [nsstring stringwithformat:@"%@", infinity]; } else self.displayfield.text = [nsstring stringwithformat:@"%.9g", result]; it can't done format specifier default. you need use sprintf , remove trailing zeros yourself. char str[50]; sprintf (str,"%.20g",num); // make number. morphnumericstring (str, 3); void morphnumericstring (char *s, int n) { char *p; int count;

1) in application have table stores settings detail used heavily every functionality.basically conditions set in table checked. now doing making db call every , fetch details , check condition.this has resulted in lot of db calls , repetitive calls same condition.there quite lot of condition records in table.we need change make perform better. 2) in previous project had same requirement have configuration table such settings configured,there implemented load configuration table @ start of application , store them in system.setproperty(name,value)..and later use system.getproperty(name) retrieve it.in case settings changed update in system property.this worked charm. however,in current case(point 1 above) don't think prev way best way because lot of records present in table having lot of columns. can suggest way how achieve such kind of behavior in java? of them can think of is 1) using system.setproperty explained. 2) using caching ehcache - standalone or hibernate(as u

on picture example of 2 situations, textured polygon being rendered. done opengl es2. a) polygon partially off viewport b) polygon inside it my question: is situation 'a)' going consume less system/gpu resources*, because texture partially off screen, or perform same if rendered inside of viewport , why? *"resources" - meaning speed, not memory. i know opengl calculate vertices first, before rendering texture , if vertices off screen/viewport, skips further calculations, same case textured object partially off screen? will omit part of texture not visible? situation should faster. vertex processing same. after that, clipping view volume applied. in situation a, part of polygon clipped, while whole polygon goes through in situation b. after that, polygon rasterized, , resulting fragments go fragment processing. since there fewer fragments in situation a, there's less work in stage. fragment shader texture sampling, visible parts of textur

i played around flask microframework, , wanted cache stats in redis. let's have dict: mydict = {} mydict["test"] = "test11" i saved redis with redis.hmset("test:key", mydict) however after restore stored = redis.hgetall("test:key") print(str(stored)) i see weird {b'test': b'test11'} stored.get("test") gives me none mydict str method result looks fine {'test': 'test11'} . so, why binary marker added restored data? checked in redis-cli , don't see explicit b markers there. wrong hgetall? this intended behavior. default, strings coming out of redis don't decoded. have couple options: decode data yourself. create client instance decode_responses argument, e.g., strictredis(decode_responses=true) . decode strings come redis based on charset argument (which defaults utf-8). you're sure every response redis has string data want decoded utf-8.

i have rectangle image use health bar fill. health goes down, width of bar decreases until 0. part of code works fine, bar's width goes down , stays in same x position width being changed. my problem when create monster different hp value, different width of health bar. how can create same size rectangle different hp value? thank much. -- create health bar monsterbar = display.newrect( 20, 160, 26, 10 ) monsterbar:setreferencepoint(display.bottomleftreferencepoint) monsterbar:setfillcolor( 80,150, 0 ) -- monster hit monsterbar.width = monsterbar.width - scorehud.text monsterbar:setreferencepoint(display.bottomleftreferencepoint) you need use percentile intermediate value, can use in progress bar. for example, compute monster health percent that, making sure hp current <= hp max: local nmonsterhppercentile = (nmonsterhpcurrent / nmonsterhpmax) * 100 once have percentile value, adapt rectangle created max size of "100" example (or 200, 300 etc

for pki certificate generation , , setting serial number , used rand_bytes 20 bytes of random serial number, wanted char * set serial number of certificate , seems of type asn1_integer * tried asn1_type_set_octetstring(asn1_type *, unsigned char *, len) since takes asn1_type * , not asn1_integer* gave crash how convert between unsigned char * asn1_integer ? thanks, i'm sure you're looking for, wrong. if want have 20-byte asn1_integer 1 way sending through bignum library first : unsigned char data[20] = {0}; rand_bytes(data, sizeof(data)); data[0] &= 0x7f; // build big number our bytes bignum* bn = bn_new(); bn_bin2bn(data, sizeof(data), bn); // build asn1_integer our bignum asn1_integer* asnint = asn1_integer_new(); bn_to_asn1_integer(bn, asnint); // todo: use asn1_integer // cleanup asn1_integer_free(asnint); bn_free(bn);

i have class called class.feed.php , how include composer such when 'vendor/autoload.php' included or required in example index.php , class included? note, still php newbie. here's example of using composer. { "autoload": { "psr-0": {"appname": "src/"} } } set structure follows: src/ - appname/ vendor/ composer.json index.php place classes inside appname folder, use namespace class relative src folder. classes should have same filename class name starting capital, example class called demo in appname: <?php namespace appname; class demo { public function __construct(){ echo 'hi'; } } then in root create index.php include autoload vendor once composer has been installed. to use class call namespace followed class name <?php require('vendor/autoload.php'); $demo = new \appname\demo();

there nice rich text editor scribe . in app have multiple editable divs on page, , on every focus event on particular div want turn div editable mode scribe. on blur event destroy instance of scribe, due fact having seperate instance every div high memory consuming. this amd module attaches scribe instance given dom element: define(['scribe'], function (scribe) { 'use strict'; function init(element) { var scribe = new scribe(element, { allowblockelements: true }); //... } return { attacheditor: init }; }); this piece of code makes use of module above: $('.editable').focus(function(e) { editormodule.attacheditor(e.target); }); and can't figure out how detach or destroy existing scribe instance. tried code: define(['scribe'], function (scribe) { 'use strict'; var scribe; function init(element) { scribe = new scribe(element, { allowblockelements: true });

i used files.createtempfile("hello", "txt"); to create temporary file , stored returned path . i have eclipse ifile resource linked temporary file created: linkedfile.createlink(tempfile.touri(), iresource.none, null); if want path resource, call linkedfile.getlocation().tofile().topath() on local machine, works 100% fine. on remote test machine, 2 different paths: from files.createtempfile: c:\users\userna~1\appdata\local\temp\hello3606197456871226795txt from getlocation().tofile().topath() c:\users\username_testing\appdata\local\temp\hello3606197456871226795txt the folder username_testing , folder gets turned short filename, , direct creation of temporary. these 2 paths not considered equal path.equals(...) , causing failing of tests on remote machine. in general, makes me bit nervous using path.equals(...) though in actual real operation of application haven't had issues yet. there way can force system always use long filena
