i new user of airbnb open source workflow/datapipeline software airflow, on github url https://github.com/apache/incubator-airflow . there dozen of default example dags after web ui started. make me feel stupid tried many ways remove these dags , failed so. load_examples = false set in airflow.cfg. folder lib/python2.7/site-packages/airflow/example_dags removed. states of example dags changed gray after removed folder of dag pythons scripts. items still occupy web ui screen. , new dag folder specified in airflow.cfg dags_folder = /mnt/dag/1. checked dag folder, nothing there. weird me why difficult remove these examples. when startup airflow, make sure set: load_examples = false inside airflow.cfg. if have started airflow not set false, can set false , run airflow resetdb in cli (!which destroy current dag information!). alternatively can go airflow_db , manually delete entries dag table.

might wrong forum - please redirect if know correct path - thanks. in google analytics sessions attributed first page visited , not meant used on pageview level. that makes sense me on our full website view. however, have using view filters show traffic section /explore. know how should interpreting sessions reported on view? person wanted take total sessions view , divide total sessions whole site view acquisition traffic section. besides being inefficient way go - wrong? if anything, think tell percentage of total traffic section receives - not acquisition or 'first touch' traffic, right? because filtered view means traffic there treated first touch session , not compared larger site data. think i've answered own question already. if has wisdom add i'd appreciate it.

i learning javascript , discovered variable named name , predefined, sitting in global context. i created new, clear html file (have not written html in it). tested in chrome, opera , firefox, same... i wonder why that, beyond curiosity, there case when variable assigned value "string" , itself, have not touched it. why there? doing? window.name 1 of predefined property of global object window . since stephan bijzitter wants answer more details, here is. section 7.3.1 of current living html standards states window.name property of global object window returns name of window , can set, change name. the name attribute of window object must, on getting, return current name of browsing context; and, on setting, set name of browsing context new value. the name gets reset when browsing context navigated origin.

i have data model in entity a contains references 2 other entities, b , c . if either b or c deleted, want a deleted. when creating a , it's possible name either b or c parent. possible name both b , c parents if either b or c deleted, a deleted? in more concrete terms, search results, result might have both category , region , web page birds in north america. result stored reference category , region. later, want delete category birds , want result deleted. likewise, delete region north america , want result deleted. i hate go on @ such length such trivial scenario. doesn't seem covered in of datastore documentation. missing? flawed data model? single-parent limitation: a child can have 1 parent in datastore. in other words, a can child of b or c , not both. of course, parent can have multiple children, though. alternative: you can use keyproperty repeated=true argument , store many entity keys on it. in python, this: class a(n...
