i have several tables, each massive amount of data (20mb each). let's call them table_1, table_2, table_3, etc. structure of these tables similar, identical column headers (but varying number of rows). let's attribute_a, attribute_b, etc. i interested in performing calculations on attribute_b each table. these calculations involve looping through attribute_b. i start creating master list of table names. table_list = [table_1, table_2, ... table 10]; now can iterate through , perform calculations. doing single calculations works fine using eval , concatentation of column vector name function of value of current_table: for current_table = table_list peak_value = max(eval(strcat(current_table,"attribute_c"))); i run trouble when perform calculations require iterating through column vectors. instance, following fails. for current_table = table_list = 1:length(eval(strcat(current_table,".attribute_b") x = x + eval(strcat(current_

i trying create file "varstore.dat" (that not exist prior running this) should contain value 0. every time execute script, want increment value 1. so trying create file 1 time, read file, , rewrite(or overwrite) file upon each execution. however, problem each time run program, initialize 0 , output 1. trying rewrite varstore.dat , new value become old value next time execute script. def get_var_value(filename="varstore.dat"): open(filename, "a+") f: val = int(f.read() or 0) + 1 f.seek(0) f.truncate() f.write(str(val)) return val your_counter = get_var_value() print("this script has been run {} times.".format(your_counter)) you need f.seek(0) before val . def get_var_value(filename="varstore.dat"): open(filename, "a+") f: f.seek(0) val = int(f.read() or 0) + 1 f.seek(0) f.truncate() f.write(str(val)) return val the

i'm using django-hosts package manage content that's supposed set in various different subdomains. started making view in form used change something. once form validated , processed, user supposed redirected other page. looking through documentation there's easy way render(): settings_url = reverse('settings', host='dashboard') return render(request, 'dashboard/settings.html', {'settings_url': settings_url}) however, there's no mention of redirect(). how go redirecting somewhere else, instead of usual return redirect("dashboard:settings") myapp/hosts.py : host_patterns = patterns('', host(r'www', settings.root_urlconf, name='www'), host(r'dashboard\.myapp\.com', 'dashboard.urls', name='dashboard'), ) dashboard/urls.py from .views import home, websitesettings urlpatterns = [ url(r'^$', home, name='home'), url(r'^settings/$',

streight doubt: so, if kernel not read gmem (only reads @ begin), , uses gmem storage storage only, writing gmem stall warp reading gmem do? background: the kernel sweep across set of partiotioning patterns can predicted , managed. single pattern may use lot of sem , registers calculated , advanced. if statistical value of specific parttern higher previous highest value among processed values in warp, highest value replaced , pattern has saved. kernel carries on evaluationg alternative patterns until end. number of alternative patterns high , necessary recover alternative pattern of highest statistical value @ kernel end , every warp should elect 1 winning pattern (every warp can have own space in gmem) , can keep highest value in register. using more sem store best pattern reduces pattern lenght or number of threads in block, may work to... indeed initial problem little computing in warp call each pattern (poor performance)... thanks in advance

#1 code $row = $result->fetch_assoc()); while ($row) { // code here } #2 code while ($row = $result->fetch_assoc());) { // code here } why #1 code , #2 code give different result? because in #1 execute fetch_assoc() once, while in #2 execute on every loop iteration. in other words, in #2 fetch_assoc() keep on returning rows long there rows available in result set. #1 enter infinite loop if there @ least 1 row available.

i want show spinner during execution of synchronous task. set showspinner = true before task starts , showspinner=false after finishes. however, spinner doesn't show. think because expensive task block dom update *nfif="showspinner shows spinner. how fix this? thinking of using lifecycle hooks not sure how to. updateimagedata() { if (this.cropsizechanged) { this.showspinner = true; var imgdata = this.cropper.getcroppedcanvas().todataurl(); //**expensive** this.editedimage = imgdata; this.cropsizechanged = false; this.showspinner = false; } console.log("updated imagedata"); if(this.istaggableimage) { settimeout(() => {this.croppedimageboundingrect = this.croppedimageref.nativeelement.getboundingclientrect();}, 100); } } the reason why spinner not showing setting false straight away after making expensive call. can try 2 following things if expensive call returns callback or pr

why api's use different urls? there 2 different interfaces on web server? 1 processing api requests , other web http requests? example there might site called www.joecoffee.com use url www.api.joecoffe.com api requests. why different urls being used here? we separate ours couple of reasons, , won't apply. separation of concerns. we write api code in 1 project, , deploy in 1 unit. when work on api worry , don't worry page layout. when web work, that's separate different authentication mechanisms. the way tell user log in quite different how tell api client it's not authenticated. different scalability requirements it might api lot of complex operations, while web-server serves more or less static content. might want add hundreds of api servers around world, have 10 web servers. different clients you might have api web client , separate api mobile client. or perhaps public 1 , private / authenticated one. might not apply example

i have sevral modules a b c and each module has core module 1 of dependency a+core b+core c+core and i'm supposed package a,b,c in d managed exclude core modules b , c , kept core module in a d |+ a-core |+ b-removed core |+ c-removed core what best thing in situation, bad practise ? you may have more 1 dependency pulls core dependency in d pom.xml so, exclusion not required. important thing here a , b , c depends on same version of core dependency otherwise d packaging include version of core rather one. may compile without error, generate exceptions @ runtime if use of these 2 versions not compatible between them. so focus on using unique version of core in a , b , c . using parent pom or creating dependency aggregating common dependencies tools ease that.
