javascript has function parseint() can convert integer in binary form decimal equivalent: parseint("101", 2) // 5 however, need convert binary fraction decimal equivalent, like: 0.101 = 0.625 i can write own function calculate result following: 1 * math.pow(2, -1) + 0*math.pow(2, -2) + 1*math.pow(2, -3) // 0.625 but i'm wondering whether there standard already. you can split number (as string) @ dot , treat integer part own function , fraction part function right value. the solution works other bases well. function convert(v, base) { var parts = v.tostring().split('.'); base = base || 2; return parseint(parts[0], base) + (parts[1] || '').split('').reduceright(function (r, a) { return (r + parseint(a, base)) / base; }, 0); } document.write(convert(1100) + '<br>'); document.write(convert(0.0011) + '<br>'); document.write(convert(1100.0011) + '<br&g

i checking 3 strings equality; var str1 = "hello world!"; var str2 = "hello \ world!"; var str3 = "hello" + " world!"; //console.log(str1===str2);//true // console.log(str2===str3);//true console.log(str1 === str2 === str3); //false how can check scenario want compare 3 variables? your question isn't totally clear me.  assuming question how compare equality of 3 strings: with console.log(str1 === str2 === str3); you're checking (str1 === str2) === str3 (yes, associativity left right here) that is, you're comparing boolean string. what want is (str1 === str2) && (str2 === str3) assuming question how compare strings not caring numbers , types of spaces (see note below): then best normalize strings using function like function normalize(str){ return str.replace(/\s+/g,' '); } and can define function comparing strings: function allequals(strs) { var p; (var i=0; i

i'm trying take @ locks happening on specific tables in postgresql database. i see there's table called pg_locks select * pg_locks; which seems give me bunch of columns possible find relation because see 1 of columns relation oid. what table must link to relation name? try : select nspname,relname,l.* pg_locks l join pg_class c on (relation=c.oid) join pg_namespace nsp on (c.relnamespace=nsp.oid) pid in (select procpid pg_stat_activity datname=current_database() , current_query!=current_query())

i have simple question. loading large extrenal source of data using spark map<string, string> options = new hashmap<string, string>(); options.put("url", "jdbc:postgresql:dbserver"); options.put("dbtable", "schema.tablename"); dataframe mydf= sqlcontext.read().format("jdbc"). options(options).load(); i wanted know if external sql database updated changes reflect data frame or again need call load function populate dataframe. in case need call load function again,is there more efficient way in spark can update data frame when external sources change? short answer doesn't details relatively subtle. in general spark cannot event guarantee consistent state of database. each executor fetches own part of data inside separate transaction if data actively modified there no guarantee executors see same state of database. this becomes more complicated when consider explicit , implicit (shuffle files) caching

is possible train model based on training , validation data sets.basically end combining both of them create new model. , combined model use classify of data in test dataset. this done. assuming know how transfer hyperparameters, fit model on train data, select hyperparameters based on score on valid one. when combine train + valid bigger dataset, "optimal hyperparameters" might different ones selected before. in general - yes, done, might more tricky expect (especially if method highly stochastic, non deterministic, etc.).

if handle http request on server side using spring framework, how can check connection limit , how increase connection handling capacity. if 1 have solution please me. the http connection handling depends on configuration of web/application server. example in tomcat in server.xml, following parameters of http io/nio connectors can configure number of connections server can handle. maxconnections - maximum number of connections server accept , process @ given time. when number has been reached, server accept, not process, 1 further connection. additional connection blocked until number of connections being processed falls below maxconnections @ point server start accepting , processing new connections again. acceptorthreadcount - number of threads used accept connections. more 2 not required in multicore machines. other parameters affect same - connectionlinger , connectiontimeout etc. for more details check this

using netbeans 7.3, trying connect cloud sql instance. have authorized project on local machine gauth using python 2.7. though create oauth 2.0 tokens needed when test connection using "com.google.cloud.sql.driver", connection cannot established. plan deploy java application on app engine, using kind of orm againts any suggestions make connection work? i had same problem yesterday : must download , launch google cloud sql command line tool. allow authorize google account access cloud sql service oauth2 authentication on local machine. follow steps described here : https://developers.google.com/cloud-sql/docs/commandline once application deployed on app engine, need configure database allow application access it. that's pretty straightforward, see google apis console : https://code.google.com/apis/console/ edit : can use simple mysql jdbc connector , configure cloud sql instance fixed ip. means can access cloud sql instance anywhere classic mysql datab

its been 2 months since started learn rails doing modifications on plugin of redmine in enterprise (as student learning way of "life"), problem cant find solution anywhere. let me explain: i needed group huge ammount of time entries user_id , project_id(no problems that) if need sum hours in groups. the estructure this: | id | project_id | user_id | issue_id | hours | and information built method : def time_entries_for_user(user, options={}) extra_conditions = options.delete(:conditions) return timeentry.select('*,sum(hours) sum_hours'). includes(self.includes). where(self.conditions([user], extra_conditions)). group('issue_id, time_entries.project_id'). order('issues.id asc') end i added select because needed column plus sum 1 , group alone works , cant make sum columns appear. json code result of method: {"test1 / subproyectotest1":{"logs":[{"id":24,"project_id

i try create simple calculator c. numbers , operators should parameters. have main function , calculate function: main: int main(int argc, char *argv[]){ long result; long number1 = strtol(argv[1], null, 10); long number2 = strtol(argv[3], null, 10); result = calculate(number1, number2, argv[2]); printf("result: %li", result); return 0; } calculate: long calculate(long number1, long number2, char operator){ long result; switch(operator){ case '+': result = number1 + number2; break; case '-': result = number1 - number2; break; } return result; } when start program this: ./calc 1 + 2 the result 0. think there problem operator parameter, because when write '+' instead of argv[2] works. dont know how fix it, works parameter, too. one problem calculate function expects char , main passes c string. problem when unexpected parameter passed, switch fails set result , l

i using following code app base directory: // /private/var/mobile/applications/exampleid/example.app/ fappdatadirpath := gethomepath + pathdelim + application.title + '.app' + pathdelim; // /private/var/mobile/applications/exampleid/example.app/library/ fappdatalibrarydirpath := fappdatadirpath + 'library' + pathdelim; on ios simulator both these paths exist. however, on ios device fappdatadirpath exists. "library" variation can not created using e.g forcedirectories what wrong? :(

id <- 1:10 group <- c(1,1,1,2,2,2,3,3,3,3) var1 <- c(6:15) var2 <- c(7:16) var3 <- c(6:11, na, na, na, na) var4 <- c(4:9, na, na, na, na) data <- data.frame(id, group, var1, var2, var3, var4) library(dplyr) data %>% group_by(group) %>% boxplot(var1, var2) the last line not work wish. idea 4 boxplots in 1 graphic. 2 each variable. maybe need use ggplot2? you need reorganize data if want both variables in same plot. here ggplot2 solution: # load library library(ggplot2) library(tidyr) library(ggthemes) # reorganize data df <- gather(data, "id","group") #rename columns colnames(df) <- c("id","group","var","value") # plot ggplot(data=df) + geom_boxplot( aes(x=factor(group), y=value, fill=factor(var)), position=position_dodge(1)) + scale_x_discrete(breaks=c(1, 2, 3), labels=c("a", "b", "c")) + theme_minimal() +

i have followed next guide https://hub.docker.com/r/iliyan/jenkins-ci-php/ download docker image jenkins. when start container using docker start containername command, can access jenkins localhost:8080 . the problem comes when change jenkins configuration , restart jenkins using docker stop containername , docker start containername , jenkins doesn't contain of previous configuration changes.. how can persist jenkins configuration? you need mount jenkins configuration volume, -v flag you. (you can ignore --privileged flag in example unless plan on building docker images inside jenkins docker image) docker run --privileged --name='jenkins' -d -p 6999:8080 -p 50000:50000 -v /home/jan/jenkins:/var/jenkins_home jenkins:latest the -v flag mount /var/jenkins_home outside container in /home/jan/jenkins maintaining between rebuilds. --name have fixed name container start / stop from. then next time want run it, call docker start jenkins

i trying calculate percentage of number (taken 1 text field) , set calculated value form field. have tried below code observing mismatch in key event/decimal places js detecting. for example if provide 100 in first input field (to calculate percentage of 1.75), based on js code expect 1.75 in second text field coming 0.175. know simple calculation unable solve this. var refee = document.getelementbyid("estimated referral fee"); var lnamt = document.getelementbyid("loan amount"); refee.disabled = true; lnamt.onkeydown = function isnumber(evt) { evt = (evt) ? evt : window.event; var charcode = (evt.which) ? evt.which : evt.keycode; if (charcode > 31 && (charcode < 48 || charcode > 57)) { return false; } calcper(lnamt.value); } function calcper(amtval) { var pernum = 1.75; refee.value = (pernum / 100) * amtval; } <div class="form-group"> <label class="contro

i have application written in excel/vba reads text files written in unix. these files consist in finite element modeling simulation settings, each line in 20k+ text file individual setting. application searches particular setting , returns them user in plain english. particular line this: model.settings.excitation.modes=50 so far, line of code worked find text between '=' sign , end of line instr(1, filecontents, vblf) where filecontents whole text file after '=' symbol. something somewhere upstream of application has changed assumed carriage return character 'vblf' cannot found, there when viewing in notepad++. application depends on finding carriage return, , doesn't work. i have tried using : asc(mid(adsfilecontentsx, 3, 1)) to isolate carriage return character end character next line, doesn't work either. i tried of below well instr(1, filecontents, vblf) instr(1, filecontents, vbcrlf) instr(1, filecontents, vbcr) instr(1, fil
