i write objects out database in xml form. however, if change form of objects, changing name or changing fields, can no longer read them database, makes difficult task of reading them, converting them new form, , writing them out database. i'd rather not have rename classes everytime change them. *note: relying on c#'s xmlserialization/deserialization of objects generating xml. perhaps not desirable if change format of objects. if implement iserializable interface on objects, can implement custom serialization/deserialization routines provide backwards compatibility older versions of objects. see here example of how can done: iserializable , backward compatibility

i'd plot data such on y axis there probability (in range [0,1]) , on x-axis have data values. data contiguous (also in range [0,1]), i'd use kernel density estimation function , normalize such y-value @ point x mean probability of seeing value x in input data. so, i'd ask: a) reasonable @ all? understand cannot have probability of seeing values not have in data, interpolate between points have using kernel density estimation function , normalize afterwards. b) there built-in options in ggplot use, override default behavior of geom_density() example doing this? thanks in advance, timo edit: when said "normalize" before, meant "scale". got answer, guys clearing mind this. this isn't ggplot answer, if want bring ideas of kernel smoothing , histograms bootstrapping + smoothing approach. you'll beat head , shoulders stats folks doing ugly things this, use @ own risk ;) start synthetic data: set.seed(1) randomdata <- c(r...

i see web protection library (wpl) comes 2 different options: security runtime engine (sre) antixss library the first 1 seems great since no code necessary, it's httpmodule. second requires manually add escaping logic on code. despite advantage mentioned, sre not popular , i'm wondering why. there known problem library or big advantage of using antixss i'm not seeing? thanks! the biggest flaw see in sre looks me reliant on "blacklisting" behavior. example, tries detect sql statements in order provide sql injection protection. blacklisting weak, fact have know potentially harmful input in order provide 100% protection. http://www.owasp.org/index.php/data_validation#data_validation_strategies that not don't see value in sre. think looks nice tool have in arsenal, considered additional layer of defense. the other disadvantage see using library may encourage coders lazy learning how secure applications. relying on individual too...

suppose have location listener might listening location updates network provider. want whenever user enables gps listener stop using network , start listening gps. my understanding whenever provider enabled sends message onproviderenabled() method passing in string name. what actual value passed in gps? "gps", "gps" or "gps_provider"? thanks mike the sdk documentation provides current value of string literals each defined constant: http://developer.android.com/reference/android/location/locationmanager.html#gps_provider you can see value locationmanager.gps_provider "gps". however, in code should refer value constant locationmanager.gps_provider . hope helps!

is there place find multiple assignments implementing design patterns( along solutions ?) my idea hands on in proper way. implement in java. @ moment need basic design patterns , not j2ee patterns. i'm looking complete application developed uses of design patterns. (all design patterns in single assignment) build me antfarm!! you want assignment? i'll give one. it's due tuesday, february 22 @ 9:00pm pacific time. going build me antfarm, , you're going use common design patterns it. this not have every design pattern, because that's silly. does, however, have enough interactions complex while being simple enough implement quickly. once done, can @ adding in more features our ant farm! i add requirements (with revision added) needs arise. here's requirements: functional requirements : a meadow can have many ant farms in them. assignment, ever allow 1 meadow take place. a meadow should capable of spawning logically unlimited number of...
