in r, need create vector b = (1, 1+pi, 1+2pi, 1+3pi,...,1+19pi) . unsure how this. keep trying use seq command (i.e. seq(1, 1+npi n = 1:19) , that's totally wrong!), don't know proper syntax make work, never does. any appreciated. r needs multiplication operator. b <- 1+ seq(0,19)*pi or faster in situations speed might matter: b <- 1+ seq.int(0,19)*pi you use equivalent: b <- 1+ 0:19*pi because ":" operator has high precedence ( see ?syntax ), it's reasonable safe. careful understand precedence when use minus or plus sign might parse binary operator (remembering spaces ignored , unary-minus has higher precedence single-colon, binary minus or plus has lower precedence : > 1: 5+5 [1] 6 7 8 9 10

if escaped characters in regular expression created in javascript regexp object need escaped again how following code in sizzle.js work - identifier = "(?:\\\\.|[\\w-]|[^\0-\\xa0])+" if \\\\\\\ = \ , \\\w = \w how \0 = \0 when single backslash used? when run in google console identifier "(?:\\\\.|[\w-]|[^-\\xa0])+" is mistake or not understanding correctly? if correct , how intended work purpose of \0 ? if regular expression needs contain backslash — e.g., because need \( (which matches actual ( ) or \w (which matches letter or digit or underscore) — , you're creating regular expression string literal, need write \\ , ends \ in regular expression. but in \0 example, regular expression doesn't need contain backslash. needs contain character u+0000 (which matches itself). string literal can contain \0 , ends character u+0000.

i'm confused after looking through similar questions of the(!) operator when prefixed on variable or other object in if statements, functions, etc? example: mutating func add(value: t) { if !contains(items, value) { items.append(value) } } the exclamation mark ! used 2 purposes. when see appear @ beginning of object, such in !contains(items, values) , means "not". example... let x = 10 let y = 5 if x == y { print("x equal y") } else if x != y { print("x not equal y") } the above code print => " x not equal y " . the logical not ( ! ) operator can used reverse boolean values. example... var falseboolvalue = false falseboolvalue = !falseboolvalue print(falseboolvalue) the above code print => " true " in addition usage logical not operator, exclamation mark used implicitly unwrap optional values. whenever see exclamation mark appear @ en...

hi need orders belongs or contain product. ie if product1 product name need orders in loop contain product . order detail use following query $args = array( 'post_type' => 'shop_order', 'post_status' => 'publish' ); $loop=new wp_query($args); while($loop->have_posts()): $loop->the_post(); $order_id=get_the_id(); $order = new wc_order($order_id); ..details fetched query .. endwhile ; to item details can use $order->get_items(); want to (1) best method fetch order details in loop ? (2)how fetch orders belongs product1 [where product1 product name ] .? is know ,please . for first question yes need think on it, second question can use following, <?php global $wpdb; $produto_id = 22777; // id produto $consulta = "select order_id {$wpdb-...

how can unrelated processes cooperate using futex? let's have unrelated processes, 1 being, say, apache subprocess module, being e.g. background script. i'd establish condition variable mutex between 2 using futex, benefit user-space fast code path. it seems me memory @ mutex stored in mmap 'd file, if memory mapped, e.g. mlock 'd 2 processes theoretically issue futex calls against same address. alternatively, perhaps futex can passed 1 process using futex_fd . code submissions low-, high-level , dynamic languages accepted (c, c++, python, etc.). "robust futex" api must supported too. references: https://www.kernel.org/doc/documentation/robust-futexes.txt http://locklessinc.com/articles/mutex_cv_futex/ thanks phillip , felix m. pointers. python user code (file data structures exists, initialised pthread_process_shared ) with open("/tmp/semaphore", "rb+") f: m = mmap.mmap(f.fileno(), 0) # default: fil...

although have found many answers on how draw bivariate normal distribution ellipse on existing plot, have question regarding plotting ellipse onto existing plot x- , y-axis log-transformed. as example have following data add ellipse library(mixtools) library(truncnorm) x<-rtruncnorm(n=100, a=0, b=20) y=1+.3*x+.3*rnorm(100) data<-cbind(x,y) mu <-c(mean(x), mean(y)) sigma <- var(data) plot(data) ellipse(mu, sigma, alpha=0.1, npoints = 200, newplot = false) however, actual data requires use log transformed x- , y-axis, so plot(data,log="xy") when plotting "ellipse" function, no longer ellipse ellipse(mu, sigma, alpha=0.1, npoints = 200, newplot = false) adding "log" ellipse function specifications no option ellipse(mu, sigma, alpha=0.1, npoints = 200, newplot = false,log="xy") warning message: in plot.xy(xy.coords(x, y), type = type, ...) : "log" not graphical parameter. can me out one? tha...

i want configure nhibernate once , reuse session factory open different sessions manipulate database, hubs considered transient objects , loose object state when client initializing request hub. way far have read make objects static in order reuse it. is there other way of achieving without making objects static ? myconfiguration = new configuration(); myconfiguration.configure(); mysessionfactory = myconfiguration.buildsessionfactory(); mysession = mysessionfactory.opensession(); thank in advance :) there nothing wrong having configuration , sessionfactory objects stored in static fields. sessions should not shared. an alternative use di container , register them singletons.

i have been searching through entire internet sometime , not able understand whether jcron api java scheduling or specific joomla cms ? if can used java can share links of example. thanks in advance from jcron web page : jcron scheduler joomla component cron jobs management , scheduling! it's purpose simulate cron jobs through joomla front end interface @ preset periods of time users either don't have access server crontab or don't want use purpose! it belongs joomla world, , has nothing java. if looking cron scheduling in java should check cron4j .
