i developing package can used without writing new code , modules can used develop new code (see documentation ). many of modules use logging in simple way: import logging import sys logging.basicconfig(format='%(asctime)s %(levelname)s %(message)s', level=logging.debug, stream=sys.stdout) # code of module follows i have these lines in many modules. seems me should factor out, not sure best / recommended / pythonic way is. the relevant parts in logging documentation seem configuring logging library , logging multiple modules . i guess should move line logging.basicconfig executables ( bin/hwrt ) , remove other logging.basicconfig lines. is there rule how packages should use logging (like pep8 coding style)? if other developers use code might want disable / modify way package logging (so doesn't mixed logging calls). there way them so? your library should not configure logging; that's application-wid

how can add scientific , float number ? have like var1 0.99999899 var2 3.5008552e-05 sum 3.5008552e-05 but dont understand why in first place var2 shown scientific while in first place declared double var1, var2; so, sum var2... thanks a the way floating-point value displayed down mechanism display it. not property of value itself, nor in way stored within variable: a number number number. call "scientific" not class of numbers. it's class of representations of numbers . same way "twelve" , "12" , "xii" , "a dozen" , "iiiiiiiiiiii" represent same number. "scientific" thing exists when decide represent number in specific way (i.e. when output it). calculations don't "turn numbers scientific" same way saying "2 * 6 twelve" doesn't turn numbers english words. variables store numbers not representations. — r. martinho fernandes your display mechanism —

i have flask-restless api add , retrieve data database. of fields need localised clients there auxiliary table language , string each field. class myclass(base): __tablename__ = 'myclass' id = column(integer, primary_key = true) translated_field = relationship('translatedfield') and translation table: class translatedfield(base): __tablename__ = 'translated_field' id = column(integer, primary_key = true) myclassid = column(integer, foreignkey('myclass.id')) language = column(string(2)) value = column(text) inserts through json work fine {...,"translated_field":[{"language":"en", "value": "some value"}],...} but when same put request, sets myclassid null in existing row in translated_field table , inserts new row modified data rather updating existing one. obviously not ok because fills database garbage. question is: can modify existing rows or have &

i asking here because couldn't find answer looking elsewhere , don't know else ask this. hope can reply without saying question irrelevant forum. have biology background , using bioinformatics. need understand in lay language hash tables , suffix trees. simple, don't o(n) concepts , stuff, think both kind of same: way store string data? understand better differences. enormously other people me. lot in field now! thanks in advance. ok, lets use bioinformatics illustrate differences. let's have several dna sequences pretty long. if want store these sequences in datastructure. if want use hashtable a hashtable useful way store bunch of objects search datastructure see if contain particular object. one bioinformatics usecase can solve hashtable de-duping large sequence set. let's have huge dataset of next-gen sequenced data , want de-duplicate before assemble. can use hashtable store unique sequences. before inserting sequences hashtable, can

after shellshock issue detected on unix systems bash, have create script part of internship in firm in order update bash. prerequisites installation of updated ibm bash*.rpm are: having bash installed (simple check) having bash version under 4.2.50 i have problem dealing second part, since true bash version given command bash -version instead of rpm -qi bash gives version/release of installation package (and not neccessarily true bash version). basically, script goes this: if [[ bash installed ]] ; if [[ bash version installed < 4.2.50 ]] ; install bash version 4.2.50 fi fi bash -version returns lot of text, , pick out bash version. so far, i've used following command: $ bash -version | grep version | awk '{print $4}' | head -n 1 that returns : 4.2.50(1)-release is there way retrieve real bash version? i've played around sed command no success. seems you're trying output this, $ bash -version | a

so have form when submitted executes php file containing following redirect. echo '<meta http-equiv="refresh" content="0;url='.$nexturl.'" />'; as people know isn't clean/proffesional way of redirecting. is possible include file containing redirect using header location, require variable created in process.php file. for example create using php include: <?php include (templatepath . '/redirect.php'); ?> then within redirect.php header('location: '.$newurl); yes can redirect (that is: set/reset/unset header want) long no output happend before (none, not whitespace or bom (utf-8 byte order mark) - iirc) in case have output can capture via ob_start , output if afterwards oddly enough: made quite clear in doc

i have fact table i want create calculated member : s = sum of "tot_liv" have "num_prod" = 1 for example: s should equal 50 how ? assuming have measure defined on fact table named "tot liv", measure has "sum" defined aggregate method, , num_prod foreign key dimension named prod having attribute named num prod assume being based on primary key of dimension, , hence 1 records references num_prod primary key, use ([measures].[tot liv], [prod].[num prod].[1]) you see there no 1:1 translation sql mdx, lot of things depend on cube setup, predefines many behaviors have repeat again , again in sql queries (like usage of sum ).

i'm trying build kind of element inspector (like in chrome/ff). flow follows: you click 'start inspecting' button. you hover on necessary element. you click on element. you should see element in console. jsfiddle example here code: startinspecting = function(){ $('section *').on('mouseover.inspector', function(e){ $('.hovered-element').removeclass('hovered-element'); $(e.target).addclass('hovered-element'); $(this).on('click.inspector', function(e){ $('section *').off('mouseover.inspector'); $('section *').off('click.inspector'); $('.hovered-element').removeclass("hovered-element"); console.log(e.target); }); }); }; the problem is : each time hover on element - click event handler attached it. if hover on p element 5 times, , click on - see 5 console.log s instead of 1
