i have tried lot of things not find proper solution of how select columns can casted double or numeric when have columns of type string . , ignore rest of columns. suppose have 100 columns of type string , want check columns can casted numeric , select them , ignore other columns. for example - structtype( structfield(snapshotdate,stringtype,true), structfield(country,stringtype,true), structfield(region,stri‌​ngtype,true), structfield(probabil‌​ity,stringtype,true)‌​, structfield(bookingamount,stringtype,true), structfield(revenueamount,stringtype,true) ) here want select revenueamount , probability , bookingamount . other columns either string type or date, ignore them. is there way that? thank in advance. you can use schema method in dataframe @ structtype describe schema of dataframe. a structtype set of structfield s composing dataframe schema, can return seq[structfield] schema (returned schema on dataframe) using seq

header @ top of each several pages... footer @ bottom of each page page no i want print #header , #footer page no on every page in html print mode. i'd try css @media print @page @bottom-center @top-center. doesn't work. in theory can use: <link rel="import" href="http://example.com/elements.html"> but in real life html tag work on modern browser , not idea use option. better use php language , <?php require '...'; ?>

i have been trying figure out how params method works , i'm bit stuck on process. for example, if user clicks on blog post in index page, guess link_to method calls post controller , show action along block @post = post.find(params[:id]) , goes database find post , view displays it. so missing link seems when post id passed params method? because others explained params , i'm going answer directly question of yours: when post id passed params method i think it's best explained example; see below: say clicked link: /posts/1/?param1=somevalue1&param2=somevalue2 the rails server receives request client wants view get /posts/1/?param1=somevalue1&param2=somevalue2 address. to determine how rails server respond, server first go routes.rb , find matching controller-action handle request: # let's routes.rb contain line # resources :posts # resources :posts above contains many routes. 1 of them below # sake of example, commented above

i'm trying understand osi layer model. read flow control in handelt in data link layer (l2) , transport layer (l4). cant find methods thay use. transport layer uses flow control tcp useing window mechanism? what/how data link layer flow control? before knowing how layers controlling flow via various algorithms, must know reason why necessary. flow control in transport layer ensures delivery of message globally, 2 points of connection on protocol logically connected. whereas in data-link layer, concern deliver message locally, 2 points of connection on protocol physically connected. now, coming upon algorithms control flow of network: stop , wait - flow control mechanism forces sender after transmitting data frame stop , wait until acknowledgement of data-frame sent received. sliding window - in flow control mechanism, both sender , receiver agree on number of data-frames after acknowledgement should sent. learnt, stop , wait flow control mechanism wastes r

when running commands on lots of salt minions, can difficult make sense of output. salt '*somefilter*' state.apply some.thing now, if there 50 guests , few have problem, can lost in commandline output. is there way filter output feedback failed states? or in general better way 'parse' output (as human) scrollback huge buffer? we use following alias salt less output: alias salt='salt --state-output=mixed --state-verbose=false' - on 50 minions still not breeze read output - bit better full response. read more options in the cli docs , highstate docs .

is there way relatively update large number of records in sql server 2014, filtering on nvarchar(x) column, when there no index on column? eg. i'd run: update products set active = 1 productbrand = 'brand name' on product table millions of rows, , there no index on productbrand . creation of index takes around 45 minutes , update table bit faster. we want perform operation fastest way possible, creating index takes lots of time. wandering if there other ways using index. (creating index on name column , leaving there of course practice, rebuilding time time) check product table, maybe have index on productbrandid, if not, can create new tmpproduct table same structure , default 1 in "active" field. insert registers new table drop original table , rename tmpproduct product you must ensure triggers , references recreated

i having issues new angular2 function (trying rewrite v1) writing , going round in circles , cannot find advice. essentially firebase configs hold following events random fb key (eventid) event title event location useridowner useridattendee usersvsevents userid random key | eventid random key | eventid the users home page loads of events user has subscribed (eventlist), why created eventsvsuser index tree, rather looping through every event , userid. i have working (kind of). load eventvsusers tree user, each entry, use eventid load event object events , push eventlist. had reinitialize eventlist every time home page loads using push duplicates events. isn't desireable worked @ stage. the main problem if make change event in firebase directly, eventlist doesn't make changes, loads duplicate events on top of current ones. suspect because dont have subscribe firebase source directly, instead push elevments seperate array , cant keep in sync.
