i have 2 variables in sandbox based game. blocks (array) and blockssave (also array) but have these functions: var game = { blocksave: function() { blockssave = blocks; blockserasedsave = blockserased; }, blockload: function() { blocks = blockssave; blockserased = blockserasedsave; }, blockreset: function() { blocks = []; blockserased = 0; } } if call blocksave once, keeps getting saved until reset if save keep building load, loaded world after saved , builded more. if reset, though, stops saving until game.blockload(). tried functions being defined inside button onclick. i have looked through code , save function called when button pressed.

i have data containing information on prices consumers willing pay services. i'm trying find deciles each response falls into, several services using cut function. for (i in 2:13){ x<-quantile(data1[,i],c(0,.1,.2,.3,.4,.5,.6,.7,.8,.9,1),na.rm=true) data1[paste(names(data1[i]), "deciles", sep="_")] <- cut(data1[,i], breaks=x, includ) } however, have 2 problems: there variables 2 deciles same value (e.g. 0 =0, .1=0), cut function not accept. also, initial columns code work, actual decile , not decile number (for example "(1.99,2.56]" instead of .2. if has ideas, appreciate it. for first problem: can use unique breaks , pass cut . second, convert factor integer , use integer index in probs vector pull out appropriate quantile break. ## sample data, third column fail `cut` set.seed(0) data1 <- data.frame(x=rnorm(100), y=rnorm(100), z=sample(0:5, 100, rep=t)) qs <- seq(0, 1, by=0.1) ...

we using couchbase data caching , there talk of doing cross-data center replication it. however, need 1000 documents replicated multiple locations every second. documents between 2 , 64k each. is there out there xdcr experience can tell me whether feasible, or if have use other means replicate data @ speed. "benchmark" in documentation @ couchbase implies rate of xdcr 100tps. (149 ms replicate 11 documents.) the replication rate of xdcr limited network bandwidth , latency first, cpu , disk io. assuming have enough bandwidth between datacenters , clusters provisioned properly, couchbase replicate hundreds of thousands of documents per second, or more. it's pretty simple experiment run, set xdcr between 2 singles node clusters , use 1 of load generator tools come couchbase create traffic. (cbworkloadgen in couchbase bin folder or cbc-pillowfight comes libcouchbase.) there several config settings can play optimize throughput, such increasing batch size, chan...

i know can restrict google places api return addressers using option types: ['address'] . wondering if possible force user give street address including street number, "drottninggatan 100" , not "drottninggatan"? if cannot force behaviour, way of validating user has selected "drottninggatan 100" , not "drottninggatan"? (btw i'm using javascript api , angularjs) well.. can use javascript match function regex check format of input... following example check if address contains @ least number. var resultbox = document.getelementbyid("ifvalid"); function textboxchanged(){ var address=document.getelementbyid("address").value; if (address.match(/[0-9]/i)==null){ resultbox.style.color="red"; resultbox.innerhtml="not valid"; } else { resultbox.style.color="green"; resultbox.innerhtml="valid"; ...

according ecma script standard, following code should return true, doesn't: d = new date() ; d.settime(1436497200000) ; alert( d == 1436497200000 ) ; section 11.9.3 says: if type(x) either string or number , type(y) object, return result of comparison x == toprimitive(y). then, section 8.12.8 says toprimitive retuns result of valueof method. means last line in example above should equivalent to: alert( d.valueof() == 1436497200000 ); which return true , indeed. why first case not return true ? if @ spec @ section 8.12.8 , find text near end of section: when [[defaultvalue]] internal method of o called no hint, behaves if hint number , unless o date object (see 15.9.6), in case behaves if hint string . (emphasis mine) now, in step 8 / 9 of the abstract equality comparison algorithm [ 11.9.3 ] , toprimitive(x) , toprimitive(y) called without hint parameter. the lack of hint parameter, above text, means toprimitive met...
