we developing app multiple parallel streams of development. have jenkins job build each stream/release. job-a may building release 1.1, , job-b may building release 1.2. i think best have build number shared across each release, such if job-a runs build number 125, if job-b runs next run build number 126. reason think best strategy android app, requires versioncode parameter incremented each time it's submitted google play. use jenkins build number versioncode value. is there way configure jenkins share build number across multiple jobs? or, has come better solution problem? short answer use timestamps or manually set versioncodes, keep things out of ci server when not necessary. or force jenkins build numbers. long answer jenkins responsible automating works on own. if don't need jenkins setup, happy well. also if use 2 branches, commit in random orders them. trying tie jobs in ways seems unnecessary trouble problem later on. e.g. if version 2.0 built ,

to prevent clickjacking happenning website, have noticed several different methods. use javascript have website break out of iframe, other soltution set x-frame-options header deny or sameorigin. 1 of 2 method mentioned think more secure? here sample page using test clickjacking. <html> <body> <h1>clickjacking test</h1> <iframe src="http://www.google.com/" height="500" width="500"></iframe> </body> </html> with iframe break code see firefox , safari slow out of iframe, meaning see clickjacking test , break out of iframe , show original website. ie , chrome fast not noticeable. x-frame-optiions solution not see website @ all. blocked. google in above example. questions 1 of solution better? blocking or breaking out of iframe(slow in 2 browsers) in experience, setting x-frame-options (xfo) rules works better breaking out of iframes. when comes rules, depends on if absolutely have use iframes

why setting prototype property of constructor function null not prevent objects created function calling through methods on object.prototype , in same way setting prototype object.create(null) does? that is, why case: function foo(){} foo.prototype = null; console.log(new foo().tostring); //outputs function tostring() { [native code] } (or whatever) function foo(){} foo.prototype = object.create(null); console.log(new foo().tostring); //output undefined in short yes , observation correct - function constructed new operator always have object prototype in case object.prototype , indeed unlike function created object.create. on why one can see behavior specified in es5 language specification on javascript based on. let's see this. in new : quoting specification of [[construct]] method of functions indicates how object creation using new operator performed can see following specified: if type(proto) not object, set [[prototype]] internal prop

demo : http://jsfiddle.net/axrwkr/ujuu2/ var num_tabs = $("div#tabs ul li").length + 1; $("div#tabs ul").append( "<li><a href='#tab" + num_tabs + "'>#" + num_tabs + "</a></li>" ); $("div#tabs").append( "<div id='tab" + num_tabs + "'>#" + num_tabs + "</div>" ); $("div#tabs").tabs("refresh"); the new tabs syntax complicated (after 1.9 upgrade).. one more question, 1.9 onward remove method had been depreceated, if want remove particular tab, should use remove() remove tab element , appended div (content)? sound un-practical.. add in end of $("button#add-tab").click(function() demo $('a[href=#tab'+num_tabs+']').click(); //click new tab link make active or can use active option demo $("div#tabs").tabs("ref

i have .csv file of geological formations , occurrences of fossil species @ each formation. each fossil has own row in .csv file, formation name included in row. the code wrote below printed out number of formation occurrences fine. import csv collections import counter out=open("bivalviagrdwis.csv", "rb") data=csv.reader(out) data.next() data=[row row in data] out.close() formations = [] row in data: if row[13]=='': continue else: formations.append(row[13]) print counter(formations) however, there may duplicate fossil names ruin count; want number of unique fossils @ each formation. can add count unique elements in section of single column .csv file, rather elements? you need keep track of fossils have seen, per formation. collections.defaultdict() object makes coding easiest; keeps set per formation can test against: import csv collections import counter, defaultdict fossil = 0 # fossil name fi
