maybe question name not accurate (sorry because don't find accurate word describe question...), let me make example: the following dataframe income "week_id" , "user_id": week_id user income 1 1 100 1 2 50 2 1 200 2 2 30 2 3 150 3 1 100 3 2 150 .... i want add new column, contains "income" of previous week, looks like: week_id user income previous_week_income 1 1 100 0 1 2 50 0 2 1 200 100 2 2 30 50 2 3 150 0 3 1 100 200 3 2 150 30 .... it looks generate new column information other rows, other current row. i know solution apply function, it's row row, seems slow case ( origin dataframe may tens of millions of rows ), wonder other fast solution result? the background generate factor predictive analysis, want use previous week income 1 variable when predict current wee

i have view height directly proportional height of parent view. within view there 2 buttons , spacer view. want heights of buttons increase first , height of spacer view increase lower priority. purpose have set heights of buttons equal, , given 2 additional constraints first button i.e 30 <= height <= 50 . have assigned spacer view height >= 30. if space available, want buttons grow up-to size of 50 , if still space available spacer view fill-up remaining area. achieve have given buttons content hugging priority(vertical) 200 , spacer view has higher content hugging priority(vertical) 300 . not working expected. missing or doing incorrectly?

my current task make jenkins job download git repo, gulp build project , sync data s3 bucket. trouble gulp build command root can't find. i read that post installing nvm globally , after using: wget -qo- https://raw.githubusercontent.com/xtuple/nvm/master/install.sh | sudo bash was able install nvm /usr/local/nvm. inside project directory (/var/lib/jenkins/project) run: sudo /usr/local/bin/npm install and modules go node_modules dir inside project dir. then do: sudo gulp build --env=production sudo: gulp: command not found it looks root can't find gulp . inside node_modules/gulp/bin there gulp.js file have no idea how use it. so how can make gulp build work root? installed , build project minor effort using regular user , know project ok, problem manifested after switching root. my working env amazon linux node.js version 4.4.7. these first steps nvm, gulp , node.js whole, please, don't harsh if i'm doing stupid. i think have inst

i new .net core , having doubt portable libraries. i have created .net core web application, , framework section of project.json looks follows: "frameworks": { "netcoreapp1.0": { "imports": [ "portable-net4+netcore45" ], "dependencies": { "microsoft.netcore.app": { "version": "1.0.0-*", "type": "platform" } } } } now in above case, meaning of "portable-net4+netcore45"? does mean, can run .net core application on machine .net framework 4 installed? will work without .net core installation? no, above still require .net core installed, because using "type": "platform" , requires platform installed , package serves reference. if want run w/o .net core framework/sdk being installed, have change to "dependencies": { "microsoft.netcore.app": "1.0.0" }, "frameworks": { "netcoreapp1.0&quo

i'm working physics in javascript , have value indicating number of contacts in "physical" world. value can between 0 - 6. problem fluctuates lot. want filter out spikes. number 3 , fraction of second changes 0 , 3 again. ideas how best this? a fit can median filter in sliding window. consider last n values, n @ least twice duration of drop. filtered value median of n. repeat forever n samples shifted 1 position. as values discrete in tiny range, median algorithm simple. keep histogram of 7 possible values, i.e. 7 counters. whenever shift 1 position, count down oldest value , count new. median value such cumulated counts reaches n/2. there inertia, i.e. true changes take time acknowledged, unavoidable because algorithm needs confirm permanent change vs. temporary drop.

i have following problem: search term , results. fine. if term exists hyphenated word in solr index, result containing word higher score/ shown on top of results. i have tried change third result entry of search , changed not hyphenated wort hyphenated one. , after reindexing document , searching same term expect same scoring before. document changed word on first place. text fieldtype looks following in schema.xml: <fieldtype name="text" class="solr.textfield" sortmissinglast="true" positionincrementgap="100"> <analyzer> <tokenizer class="solr.whitespacetokenizerfactory" /> <filter class="solr.stopfilterfactory" ignorecase="true" words="stopwords-de.txt" /> <filter class="solr.worddelimiterfilterfactory" generatewordparts="1" generatenumberparts="1" splitoncasechange="0" splitonnumerics="0" catenat
