reactjs - How do the `require`s in React's repo work? -

i'm looking extending react addon , looking through require statements looks lot of them requiring modules don't exist. how work? if i'm looking make extend reacttransitiongroup, has require('reacttransitionchildmapping');, reacttransitionchildmapping isn't module, should do? https://github.com/facebook/react/blob/master/src/addons/transitions/reacttransitiongroup.js you can see requiring bunch of things aren't npm modules. the react repo (and presumably other systems @ facebook) use custom require resolution solution based around @providesmodule annotation in various files. these compiled down standard commonjs modules via build step. check out reacttransitionchildmapping.js , you'll see following comment, part of block comment: @providesmodule reacttransitionchildmapping

list - Overriding sorting attribute in class, python -

i use bisect (as shown here, in second answer: does python have sorted list? ), instead of using list of numbers, have list of objects. in specific, objects class: https://networkx.github.io/documentation/latest/_modules/networkx/classes/graph.html i list keep graphs sorted number of nodes. if push these graphs list, looks being inserted in arbitrary way, (if run many times, changes between runs). is there "sort" function each class can define, when applying sorting used (like operator overriding in other languages) ? import bisect import networkx nx l=[] g1 = nx.graph() g2 = nx.graph() g1.add_edges_from([(1,2),(1,3),(2,3),(3,4),(4,5),(4,6),(5,6),(4,7),(7,8),(7,9),(8,9)]) print 'g1', g1.number_of_nodes() g2.add_edges_from([(1,2),(1,3)]) print 'g2', g2.number_of_nodes() bisect.insort(l,g1) bisect.insort(l,g2) print 'l0 ', l[0].number_of_nodes() print 'l1' ,l[1].number_of_nodes() if there's way of doing that, great to. thank

numpy - Applying a Fast Coordinate Transformation in Python -

i have simple 2x2 transformation matrix, s , encodes liner transformation of coordinates such x' = sx . i have generated set of uniformley distributed coordinates on grid using np.meshgrid() function , @ moment traverse each coordinate , apply transformation @ coordinate coordinate level. unfortunately, slow large arrays. there fast ways of doing this? thanks! import numpy np image_dimension = 1024 image_index = np.arange(0,image_dimension,1) xx, yy = np.meshgrid(image_index,image_index) # pre-calculated transformation matrix. s = np.array([[ -2.45963439e+04, -2.54997726e-01], [ 3.55680731e-02, -2.48005486e+04]]) xx_f = xx.flatten() yy_f = yy.flatten() x_t in range(0, image_dimension*image_dimension): # current (x,y) coordinate. x_y_in = np.matrix([[xx_f[x_t]],[yy_f[x_t]]]) # perform transformation x. optout = s * x_y_in # store new coordinate. xx_f[x_t] = np.array(optout)[0][0] yy_f[x_t] = np.array(optout)[1][0] # reshape output xx_

c# - Define multiple sinks with different outputTemplates based on logging level in xml config for Serilog -

is there way define multiple sinks in xml config serilog allow outputtemplate change based on level of log? i have: <add key="serilog:minimum-level" value="verbose" /> <add key="serilog:write-to:coloredconsole" /> <add key="serilog:write-to:rollingfile.pathformat" value="c:\logs\adapterservice-{date}.txt" /> <add key="serilog:write-to:rollingfile.retainedfilecountlimit" value="10" /> <add key="serilog:write-to:rollingfile.outputtemplate" value="[{timestamp:g}] [{level}] [{sourcecontext:l}] {message}{newline:l}{exception:l}" /> however debug level logs not include sourcecontext string in: <add key="serilog:write-to:rollingfile.outputtemplate" value="[{timestamp:g}] [{level}] {message}{newline:l}{exception:l}" /> i aware can set restrictedtominimumlevel: logeventlevel.verbose unsure how in xml.

c# - Linq To SQL Delete + Insert best practice -

as stated in title need perform delete + insert, : context.deleteallonsubmit ( deletequery ) ; foreach ( var entry in entries ) contex.insertonsubmit ( entry ) ; context.submitchanges(); as wrote in post : linq sql: execution order when calling submitchanges() i read delete operation last 1 applied, @ moment see logic work (i sure delete+insert happen dozen of times per day). need understand if post wrong or logic , reason (update check flag in linq sql datamodel?) lucky , avoid trouble. after know better pattern make "update" when record cardinality changes. mean in table there primary key identify entity (an entity has many records) , subkey identify each record in same entity (sub entity). need regenerate (because sub entity may inserted, edited or delete) use delete + insert (in messagge form write db contains entity , sub enetity exist, not deleted ones). eg: id subid data 1 1_0 father 2 2_0 father 2

java - How to use Servlets and Ajax? -

i'm new web apps , servlets , have following question: whenever print inside servlet , call webbrowser, returns new page containing text. there way print text in current page using ajax? indeed, keyword "ajax": asynchronous javascript , xml . however, last years it's more asynchronous javascript , json . basically, let js execute asynchronous http request , update html dom tree based on response data. since it's pretty tedious work make work across browsers (especially internet explorer versus others), there plenty of javascript libraries out simplifies in single functions , covers many possible browser-specific bugs/quirks under hoods, such jquery , prototype , mootools . since jquery popular these days, i'll use in below examples. kickoff example returning string plain text create /some.jsp below (note: code doesn't expect jsp file being placed in subfolder, if so, alter servlet url accordingly): <!doctype html> <html l
