we're building chrome extension our corporate environment. when user browsing web, if click on link, extension should view link , prompt user warning if link site have business relationship , warn them (and in few rare circumstances prevent them going link). we created extension that's appears button on toolbar , when user clicks on popup appears. that's good. want rid of button , have invoked when user clicks on link on whatever webpage they're viewing. extension read link , decide if should prompt user. how done though? how can make extension override href clicks?

when adding jpa facet eclipse project there choice between generic , eclipse link platforms : what pros cons of each 1 ? i intend set project glassfish , mysql glassfish ships eclipselink default jpa provider. want choose eclipselink platform enhanced persistence.xml configuration (more graphical editing example). think of way. each jpa provider supports version of jpa specification (2.0 example). each jpa provider supports proprietary extensions. if want code more portable, choose generic jpa provider. if want take advantage of features specific jpa provider, choose jpa provider platform (like eclipselink). you can take @ this document explains difference between 2 in bit more detail. example, section 4.2.5 explains different options available in persistence.xml editor options. hope helps.

i have file : #2/1/1/21=p1 5/1/1/21=p1 isid=104 3/1/1/9=p1 4/1/1/4=p1 5/1/1/17=p1 6/1/1/4=p1 isid=100 1/1/1/4=p1 6/1/1/5=p1 isid=101 i want line 1 ignored (it commented line) in line 2 want "3/1/1/9" "4/1/1/4" "5/1/1/17" in 3 variables var1 var2 , var3 in line 3 want "1/1/1/4" , "6/1/1/5" in 2 variables var1 , var2. for moment can ignore line 1, , match want on line 2 or line 3 : if {[regexp {^(\d/\d/\d/\d{1,2})=p1.*(\d/\d/\d/\d{1,2})=p1} $line value match1 match2]} { # works line 3 not line 2 } if {[regexp {^(\d/\d/\d/\d{1,2})=p1.*(\d/\d/\d/\d{1,2})=p1.*(\d/\d/\d/\d{1,2})=p1} $line value match1 match2 match3]} { # works line 2 not line 3 } how can have right number of matched line 2 , 3 ? try regex: [regexp {^(\d/\d/\d/\d{1,2})=p1.*?(\d/\d/\d/\d{1,2})=p1(?:.*?(\d/\d/\d/\d{1,2})=p1)?} $line value match1 match2 match3] ^^^

trying convert ugly mysql_ pdo i'm having difficulty creating equivalent. $rows = mysql_query("show table status"); $dbsize = 0; while ($row = mysql_fetch_array($rows)) { $dbsize += $row['data_length'] + $row['index_length']; } $decimals = 2; $mbytes = round($dbsize/(1024*1024),$decimals); echo "$dbsize"; i've done following without success: $sth = $conn->query('show table status'); $dbsize = 0; $dbsize = $sth->fetch(pdo::fetch_assoc)["data_length"]; $decimals = 2; $mbytes = round($dbsize/(1024*1024),$decimals); echo "$dbsize"; this wouldn't account $row["index_length"] this ended working me: $sth = $conn->query("show table status"); $dbsize = 0; $result = $sth->fetchall(); foreach ($result $row){ $dbsize += $row["data_length"] + $row["index_length"]; } $decimals = 2; $mbytes = round($dbsize/(1024*1024),$decimals); echo "

i'm reading book "ggplot2 - elegant graphics data analysis" (wickham, 2009) , section "scaling" (page 32) says this: scaling involves mapping data values points in space. there many ways this, here since cyl categorical variable map values evenly spaced hues on colour wheel, shown in figure 3.4. different mapping used when variable continuous. result of these conversions table 3.4, contains values have meaning computer. the book doesn't explain in detail how table 3.4, less figure 3.4. built-in database mpg . has idea how table , graph? in advance. was wondering how without coord_polar() , since example wickham's book not. turns out can use geom_point(...) . library(ggplot2) r <- seq(0,1,length=201) th <- seq(0,2*pi, length=201) d <- expand.grid(r=r,th=th) gg <- with(d,data.frame(d,x=r*sin(th),y=r*cos(th), z=hcl(h=360*th/(2*pi),c=100*r, l=65))) ggplot(gg) + geom_point(aes(x,y,
