java - Jaxb: Generate constant value for fixed-value attribute -

i'm working on xsd uses following contruct: <xs:attribute name="listversionid" type="xs:normalizedstring" use="required" fixed="1.0"> while not problematic per se, rather annoying work with, since fixed-value of definition increases between releases of xsd spec, , need modify values in seperate constants-class keep them valid, although little if of interest in xsd has changed. xsd maintained elsewhere, changing no option. thus asking myself wether there jaxb-plugin or similar turn fixed-value attributes constants ala @xmlattribute(name = "listversionid") @xmljavatypeadapter(normalizedstringadapter.class) @xmlschematype(name = "normalizedstring") protected final string listversionid = "1.0"; instead of just @xmlattribute(name = "listversionid") @xmljavatypeadapter(normalizedstringadapter.class) @xmlschematype(name = "normalizedstring") protected string listversionid; whi

java - Use of numofreducers in map reduce -

i have simple doubt in map reduce. why have set numofreducers in map reduce driver class.if not set,the default value 1.if set 100,100 reduce tasks run.what advantage of that.is reduce effort of single node.(if reduce task 1,the task running in 1 node).is there other advantages? thanks help the right number of reduces seems be: 0.95 or 1.75 multiplied (<no. of nodes> * <no. of maximum containers per node>). with 0.95, of reduces can launch , start transferring map outputs maps finish. 1.75 faster nodes finish first round of reduces , launch second wave of reduces doing better job of load balancing. increasing number of reduces increases framework overhead, increases load balancing , lowers cost of failures. the scaling factors above less whole numbers reserve few reduce slots in framework speculative-tasks , failed tasks. so main advantage load balancing , running tasks in parallel on cluster.

r - How to use .ico images in plots programmatically with/without conversion -

how use .ico image files in plots programmatically with/without conversion? my question follow-up of how convert .ico .png? , targeted r , , following specific details: i not asking methods involving transcluding icons within html , e.g. inside shiny app (author: rstudio). of course possible. can icons .ico files used directly in base-r plot, ggplot object (author: hadley wickham) , lattice plot (author: deepayan sarkar)? , approach robust printing output pdf ? how convert ico icons png or without dedicated r library. method careful handle icon's image size, depth, transparency, , other potentially important properties. the motivation there many open-source libraries of icons 1 use inside plot objects, e.g. inserting image ggplot2 , display custom image geom_point , inserting image ggplot outside chart area . in question cite @ top, how convert .ico .png? , there examples of code in c# , in python , none in r . install imagemagick on system ( your s

r - Can I pool imputed random effect model estimates using the mi package? -

it appears mi package has had pretty big rewrite @ point within past couple of years. the "old" way of doing things well-outlined in following tutorial: http://thomasleeper.com/rcourse/tutorials/mi.html the "new" way of doing things (sticking leeper's simulation demo) looks this: #load mi library(mi) #set seed set.seed(10) #simulate data (with observations missing) x1 <- runif(100, 0, 5) x2 <- rnorm(100) y <- 2*x1 + 20*x2 + rnorm(100) mydf <- cbind.data.frame(x1, x2, y) mydf$x1[sample(1:nrow(mydf), 20, false)] <- na mydf$x2[sample(1:nrow(mydf), 10, false)] <- na # convert missing_data.frame mydf_mdf <- missing_data.frame(mydf) # impute mydf_imp <- mi(mydf_mdf) although function names have changed, pretty similar "old" way of doing things. the biggest change (from vantage) replacement of following "old" functions lm.mi(formula, mi.object, ...) glm.mi(formula, mi.object, family = gaussian, ...) bay

css - HTML tag wrapping screen (by default) + content (if overflows) -

i have learnt if want make webpage wrap content of webpage, should leave width property of html tag alone height adapt automatically content. the problem that, in case, need content dynamic depends on how items have on webpage, webpage needs wrap of them. if there enough items overflows 100% of screen of computer there not problem because webpage automatically adapts content when have less items 100% of screen of computer, adapts content html tag leaves space without covering it. i in cases content more 100% of screen, webpage adapt , in cases content less 100%, html tag cover full screen(as if had set height: 100%; ). here examples: example 1 : covering content. > ok . example 2 . covering content, not full screen. > not ok . example 3 . covering full screen when content less 100% screen. > ok . example 4 . covering full screen not full content. > not ok . notice example 1 , example 2 not have height: 100%; property , example 3 , example 4 ha
