i have 2 lists: products a list of product , warehouse combination containing prices/quantities etc. two seperate results of sql queries. the second list has 'productid'. what i'm doing is: foreach(var product in products) var productwarehouses = warehouses.where(x=> x.productid == productid).tolist(); product.warehouses = productwarehouses; thing is, takes very, long. note: i've tried splitting products chunks of lists , using parallel.foreach() , tasks take time down - still takes long. use join rather doing linear search through entirety of 1 collection each item in other collection: var query = product in products join warehouse in warehouses on product.productid equals warehouse.productid warehouses select new { product, warehouses, };

i trying solve following using python: each new term in fibonacci sequence generated adding previous 2 terms. starting 1 , 2, first 10 terms be: 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ... by considering terms in fibonacci sequence values not exceed 4 million, find sum of even-valued terms. so far, have been able generate fibonacci elements in trying sum elements, code seems stall. here code below: def fib(n): if n==0: return 0 elif n==1: return 1 if n>1: return fib(n-1)+fib(n-2) n=0 total=0 while fib(n)<=4000000: if fib(n)%2==0: total+=fib(n) print(total) any suggestions welcome. you have infinite loop n isn't ever incremented 0 in while loop. additionally, why not sum fibonacci total as as find next fibonacci value in same while loop, this: x= 1 y=1 total = 0 while x <= 4000000: if x % 2 == 0: total += x x, y = y, x + y print (total) outputs: 4613732

i had comment in code review: it's better enumerate fields explicitly. "select *" doesn't guarantee order is true in case query select * (select a,b,c ...) ? can't imagine database engine re-order columns in result, imagination more logical database engines. the advice against select * when you're querying tables directly. in databases it's possible insert new column partway through table, such table t (a, b) becomes table t (a, c, b) . postgresql not (yet) support this, can still append columns, , can drop columns anywhere, can still t (a, c) if add c , drop b . this why it's considered bad practice use * in production queries, if application relies on ordinal column position read results. really, applies situations not specify fields elsewhere in query. in case in subquery. * safe , imo quite acceptable in usage. this: select * (select a,b,c ... t) is fine. this: select * t or select * (select * t) a...

i new field, might odd question. can write code(say blinking lights) in aduino ide , upload arduino , can disconnect pc , program run. (blinking happen). when using cylon.js , write program , execute say $ node blinking.js then long arduino connected pc(or laptop) blinking happens , when kill node js or disconnect arduino pc blinking stops. (this how suppose happen, right?) so question is, if have arduino temperature sensor outdoor , have cylon.js program use sensor data , things (say print them), how can achieve ? have have 2 arduinos connected via wireless or gsm shields (one outdor , 1 connected pc cylon.js running)? or there simple way of doing this? insight on appreciated. thank you then long arduino connected pc(or laptop) blinking happens , when kill node js or disconnect arduino pc blinking stops. (this how suppose happen, right?) correct. true node.js program controlling arduino, whether cylon.js or johnny-five. if have arduino temperature...

i building ionic/ng cordova app want provide access views when user has entered access code correctly. upon first launch of app, user asked set access code. how use access code provide access views topic, investigate separately. for now, concerned how save access code secure on device, such users plug device usb computer cant read code or source code of app. i thinking write custom function transforms access code encrypted string, example: function encryptaccesscode(accesscode) { return accesscode.split("").reverse().join(""); } i worried however, can read source code of app , find function, able decrypt encrypted access code string. yes, jcubic says, if md5 original access code on first launch , store in localstorage, can compare md5 of code entered each time wish verify access - cryptojs nicely. if you're worried reading source code, obfuscate it. either use uglifyjs if build process automated or manually using online obfuscato...
