ieee floating point numbers have bit assigned indicate sign, means can technically have different binary representations of 0 (+0 , -0). there arithmetic operation example in c result in negative 0 floating point value? this question inspired called question whether can safely compare 0.0f using == , , wondered further if there other ways represent 0 cause float1 == 0.0f break seemingly equal values. [edit] please, not comment safety of comparing floats equality! not trying add overflowing bucket of duplicate questions. according standard, negative 0 exists equal positive zero. purposes, 2 behave same way , many consider existence of negative implementation detail. there are, however, functions behave quite differently, namely division , atan2 : #include <math.h> #include <stdio.h> int main() { double x = 0.0; double y = -0.0; printf("%.08f == %.08f: %d\n", x, y, x == y); printf("%.08f == %.08f: %d\n", 1 / x, 1 / y,

is possible detect if serial port being sniffed process running on windows? we have application receives sensitive data cannot read other people. so, before opening serial port, need check if port being monitored. we can use createfile windows api function open serial port exclusive access rights, if monitor runs before our call, can read communication (it opens serial port shared access rights, can open port @ same time). avoid this, attempt check if port being monitored , raise exception, warning user. possible this? port sniffing requires filter driver, sysinternals' portmon utility. taking wrong kind of approach secure application. when can install filter driver, attacker has more enough privileges disable app , replace else of own making. trying detect , prevent information loss through app pointless, system has secured. serial port first thing you'll have lose, trivial tap wires.

is possible create trigger that, upon inserting or updating row, can use replace function replace characters escaped equivalents (specifically, making input html safe) columns in table without having know field names (so function can applied multiple tables). agree 115% sort of thing should done @ application level, due unique circumstances i'd add failsafe @ database level. i'm new triggers, take easy on me, want effect of: create trigger if not exists makehtmlsafe after insert on tablename begin loop on columns in tablename new.value = replace(old.value,"<","&lt;") end escaping complicated , error-prone. should never try roll own escaping function, risky. instead of making things more secure make far less secure. use specialized html escaping functions in front-end. when using php, htmlentities best bet: http://php.net/manual/en/function.htmlentities.php see also: what best practices avoiding xss attacks in php

(and how) yes, if want connect sql server using specific username , password, credentials need provided in connection string. and yes, storing them in plain text bit of risky business..... ... fortunately, .net allows encrypt entire sections of config files! read encrypting passwords in .net application , , contrary popular belief, available in of .net - not in asp.net. works in services, - not problem @ all. so store sql server connection string app.config service , encrypt <connectionstrings> section , done it!

im learning java , having problem arraylist. have read java doc , thinking maybe need hash thing? i have object called catalogue has array list of objects created class called item. each item has fields size, colour, price, product code, (these item attributes). need include method in catalogue accepts product code , searches through arraylist find object matching product code. , returns product. have tostring method in item class lists of fields & values when called. maybe should returned when matching product code found in array list? import java.util.arraylist; public class catalogue { private arraylist<item> catalogue; public catalogue () { catalogue = new arraylist<item>(); } public void finditem(int code) { if(item.code == prodcode){ } else{ system.out.println(catalogue.get(item)); } } i looked @ java doc , read hash , maybe better me use rather iterator? i'm not

how make children elements never wrap next line though parent element's width may small them? want them overflowed (e.i. overflow: hidden). need photo preview system (thumbnails) building. children elements left-floated. i found generic solution in forum. link answer and dan said, need see html , css this..

in wpf application, want set notifyonvalidationerror true (the framework defaults false) child controls/bindings if have validationrules attached binding. indeed, nice specify other binding defaults - e.g. validatesondataerrors should true. for example, in following text box don't want have manually specify notifyonvalidationerror property. <textbox> <textbox.text> <binding path="postalcode" validatesondataerrors="true" notifyonvalidationerror="true"> <binding.validationrules> <rules:postalcoderule /> </binding.validationrules> </binding> </textbox.text> </textbox> since binding markup extension create custom markup extensions extends binding , sets properties desired defaults.

i have app. cross platform. not way enterprise nor has more 500 users. no 1 wants bad it. has 3 packets available via http in source repository manager google code mac os windows , linux. need app check updates , download them , replace current executables/files around, restart app. me - see way distribute 2 applications - 1 checks updates or runs existing executable , executable itself... wonder used , there boost libs or other cross platform libs such stuff? i don't think there cross platform solution automatic updates. didn't seem able find here: how can enable auto-updates in qt cross-platform application?

i have set xml files store simple bits of data. in each case data in files structured differently, storing different types of data, simple. there file on server, can either downloaded , updated offline or updated online. here's problem: happens if while user has file offline updating file updated , want upload changes server? there way handle preferably in .net? worth nothing changes not frequent. in cases new file created major changes; we're talking minor update older files , want plan update collision if happens. for example: original file: [person] [name]bob[/name] [address]123 street[/address] [phone]123-456-7890[/phone] [/person] changes made offline: [person] [name]bob[/name] [address]124 street[/address] [phone]123-456-7890[/phone] [/person] changes made online: [person] [name]bob[/name] [address]123 street[/address] [phone]124-456-7890[/phone] [/person] ideal result: [person] [name]bob[/name] [address]124 street[/address] [phone

how following numbers, on byte conversion give results on right hand side ? guess when convert integer byte array, should convert each of digit of number correponding 4 byte array. here's cannot understand.. 727 = 000002d7 1944 = 00000798 42 = 0000002a edit: reading blog found these following lines:- if working integer column names, example, each column name 4 bytes long. lets work column names 727, 1944 , 42. the bytes associated these 3 numbers: 727 = 000002d7 1944 = 00000798 42 = 0000002a link blog: http://www.divconq.com/2010/why-does-cassandra-have-data-types/ solution the following give exact output in example: public class main { public static void main(final string[] args) { system.out.format("%08x\n", 727); system.out.format("%08x\n", 1944); system.out.format("%08x\n", 42); } } and here expected output: 000002d7 00000798 0000002a explanation how formatter works

i design application can allocate resources according rules. believe simulated annealing work, not familiar , wondering if there alternative algorithms might suitable. for example if had grid, , color each cell in grid, design algorithm find optimum or close-to-optimum solution rule set following: 1000x1000 grid must place 500 red cells, 500 blue cells, , 1000 green cells a red cell must touching red cell a blue cell must not touching blue cell a green cell may placed along edge arrangements can scored based on mean distance of colored cells upper-left hand corner would simulated annealing appropriate problem? need algorithm can compute solution reliably (seconds minutes). simulated annealing close optimal solution pretty fast. however, implementing simulated annealing correctly (which isn't code) can challenging. many people (including myself in past) implement wrong, think did right , presume algorithm isn't good. alternatives algorithms tabu searc

for python 2.5 , later, new style class, what's difference of following code snippets invoking inherited methods in subclass? class a(object): def foo(self): pass class b(a): def __init__(self): self.foo() class c(a): def __init__(self): super(c, self).foo() as long dealing single inheritance classes example gave, there not difference. in either case, python uses method resolution order(mro), (which can examine printing c.__mro__ ) find out first occurance of method foo. these both resolve base class, a's, foo implementation. however, things become interesting when have multiple inheritance. @ following example: class w(object): def foo(self): print "w" class x(w): def foo(self): #super(x,self).foo() w.foo(self) print "x" class y(w): def foo(self): print "y" class z(x,y): def __init__(self): self.foo() z.__mro__ z = z() if @ class x, can eith
