i need little 2 sheets in excel: sheet1 id name in stock 1 test 44 2 test2 55(become 50) 3 test3 66 sheet2 id name ordered 2 test2 5 end: when enter 5 in sheet2 ( ordered ) automatically subtract sheet1 ( in stock ) id 2 , name test2 . use lookup id , name, when enter 2 in id automatically show name test2 . need subtracting. know need use sumif no sure how. as correctly said in post, may use sumif. let's consider on 2 sheets, "id" in column a, "name" in column b, , "in stock" , "ordered" in column c. can calculate actual stock of third row, id "2", in cell c3 follows =55-sumif(sheet2!a:a,a3,sheet2!c:c) as expected result 50. approach way not convenient, because should add formula manually in every row of table on sheet1. suggested above others, better have @ least column put starting values of stock, can replace actual stock in figures reference relevant cell. ...

i following cs224d code recursive neural networks (see: http://cs224d.stanford.edu/syllabus.html pset 3 solutions) how code works new graph compiled each training example since each tree has different shape, suboptimal running minibatches, etc. have similar recursive graph larger input, need solution more parallelizable. i have idea precompile graphs , load them asynchronously along data gpu, similar how queue works. offload minibatch of results, compute combined gradients, back-propagate. idea can account variable input, , take advantage of gpu (have cake , eat too). is feasible?

i'm trying mind wrapped around concept of managed vs unmanaged code. correct me if i'm wrong managed code gets compiled down bytecode while unmanaged code gets compiled down machine code. is correct? from annakata's answer: managed code not compiled machine code intermediate language interpreted , executed service on machine , therefore operating within (hopefully!) secure framework handles dangerous things memory , threads you. in modern usage means .net not have to. unmanaged code compiled machine code , therefore executed os directly. therefore has ability damaging/powerful things managed code not. how used work, typically it's associated old stuff .dlls now, what's going on under hood? managed vs unmanaged all memory . in managed code, code doesn't directly manipulate memory. gives instructions runtime on code's behalf. way, unsafe or illegal operations can blocked, , code operates in semi-sandbox. managed lan...

i have smaller array as: a = np.array([2011, 2014, 2015, 2016, 2017]) aval = np.array([14, 10, 35, 40, 45]) i have array: a2 = np.array([2013, 2014, 2015, 2014, 2015, 2016, 2016, 2016, 2017]) i want create a2val such that: arval = np.array([10, 35, 10, 35, 40, 40, 40, 45]) so, trying use values in array map elements of a2 , generate extended version of a2val please note 2011 present in a, 2013 in a2 not in a2 , respectively. can use following suggested in thread: aval[np.searchsorted(a,a2)] but doesn't produce answer looking for. here 1 way: >>> aval[np.searchsorted(a, a2[np.nonzero(np.in1d(a2, a))[0]])] array([10, 35, 10, 35, 40, 40, 40, 45]) note getting expected indices in default order second array pass searchsorted() should contain common items first array.

i have created new java file within project , trying access war audio file in raw folder. have idea doing wrong? mediaplayer mediaplayer; context context; public audio() { int resid = context.getresources().getidentifier("morse","raw",context.getpackagename()); context.getresources().openrawresource(resid); mediaplayer = mediaplayer.create(this.context, resid); } you have failed start media player. try following code, mediaplayer mediaplayer; context context; public audio() { int resid = context.getresources().getidentifier("morse","raw",context.getpackagename()); context.getresources().openrawresource(resid); mediaplayer = mediaplayer.create(this.context, resid); //start media player mediaplayer.start(); } hope helps!!!...

i want dissolve polygons, , doing following: batching in shapefile (da.shp - sensitive information hence first 2 sample records , first 3 columns shown) batching in csv file called zone.csv has information dissolving joining zone.csv da (first 5 records shown due sensitivity) dissolving joined shapefile creating row ids make dissolved shapefile polygondataframe export. it goes smoothly, however, want carry zed , criteria fields in dissolved polygon, 1 can using gis. have tried search in vain, appreciated. library(rgeos) library(rgdal) library(sp) # set working directory wd <- setwd("c:/personal/r") # read da shapefile da <- readogr(wd, "da") plot(da) crs.shp <- proj4string(da) da@data[1:2,1:3] # check first 2 records objectid dauid cduid 0 3 35204831 3520 1 5 35180720 3518 # batchin text file zone numbers zones.csv <- read.csv(file="c:/personal/r/variant1.csv", header=true, sep=",") zones.csv...
