java - Multithreading for List of Objects -

-
i have list of 800 customer objects , each customer object in loop needs fetch additional data database, single thread operation taking lot of time. my approach split initial list in multiple lists of 4 , execute each list in parallel each other. can 1 come demo code skeleton problem statement. i confused whether should write db queries , business logic inside run() method of class implementing runnable interface or better approach there? 800 not large number of rows bring back. what's killing loop, you're performing separate query each of these rows. called n + 1 selects antipattern . using multiple threads not improve anything, network round trips problem before , adding threads doesn't make better. instead write 1 query join customer whatever needs, bringing data in 1 resultset. minimizes number of trips across network data.

i can't quite figure out how following in 1 line: data(attenu) x_temp = attenu$accel^(1/4) y_temp = log(attenu$dist) best_line = lm(y_temp ~ x_temp) since above works, thought following: data(attenu) best_line = lm( log(attenu$dist) ~ (attenu$accel^(1/4)) ) but gives error: error in terms.formula(formula, data = data) : invalid power in formula there's i'm missing when using transformed variables in r's formula format. why doesn't work? you're looking function i ^ operator treated arithmetic in formula, ie. x <- runif(1:100) y <- x + rnorm(100,0, 3) lm(log(y) ~ i(x^(1/4))

python - Fastest way to fetch value of just one field of an instance in Django -

-
let's have model this: class a(models.model): title = models.charfield(max_length=10) (more fields) i want fetch value of title field of instance. can either use filter : a.objects.filter(id=1).values_list('title', flat=true) which generates sql statement this: select "app_table_a"."title" "app_table_a" ("app_table_a"."a_id" = 1) limit whatever or use get : a.objects.get(id=1).title which generates this: select "app_table_a"."id", "app_table_a"."title", ... ,"app_table_a"."all fields in model" "app_table_a" ("app_table_a"."a_id" = 1) the difference in select part of queries, gives impression first approach better option. when @ execution time of statements, don't see meaningful difference , both statements fluctuate around, example, 25ms. so, question whether there difference, performance-wise (spe

jquery - Throwing PHP error vs giving a different return in AJAX -

-
i'm pretty new php, , i'm using ajax validate form upon button click. currently, i'm using if statement see whether continue on next page of multi-step form or not. $.ajax({ url: 'index.php', type: 'post', data: { myid: 1, action: action, username: user, password: pass }, success: function(data){ if (data == "continue") { wizard.next(wizard); wizard.showbuttons(); } else { helpframe.text(data); helpframe.show(); } } }); i'm wondering when use if statement above in return ajax function vs. throwing error in php, since it's understanding can somehow use code purposely cause php throw error , execute different code upon "failure".

python - How is returning the output of a function different than printing it? -

-
in previous question , andrew jaffe writes: in addition of other hints , tips, think you're missing crucial: functions need return something. when create autoparts() or splittext() , idea function can call, , can (and should) give back. once figure out output want function have, need put in return statement. def autoparts(): parts_dict = {} list_of_parts = open('list_of_parts.txt', 'r') line in list_of_parts: k, v = line.split() parts_dict[k] = v print(parts_dict) >>> autoparts() {'part a': 1, 'part b': 2, ...} this function creates dictionary, not return something. however, since added print , output of function shown when run function. difference between return ing , print ing it? print prints out structure output device (normally console). nothing more. return function, do: def autoparts(): parts_dict={} list_of_parts = open('list_of_parts.txt', 'r')

nsstring - .containsString in Swift 2? -

-
previously, when wanted see if swift string contained string, cast nsstring , call .containsstring. apple, in infinite wisdom, made version-aware, if try under s2 demand #available wrapper if target platform support (which guess bug). so best solution appears this: extension string { func contains(substr: string) -> bool { if #available(osx 10.10, *) { return nsstring(string: self).containsstring(substr) } else { return self.rangeofstring(substr) != nil } } } and check it, instead of this: if nsstring(string: line).containsstring(" ")... you use nicer looking: if line.contains(" ")... this no longer complains version, , (imho) looks better too. want too: extension string { var length: int { return self.characters.count } } apple keeps changing way length, , hope future changes api #available -able, @ point .length can modified. , these sanity: extension string

i'm reading javascript allongé , , in see code supposed return false: (() => 0) === (() => 0) when run on commandline (ubuntu 14.04) using nodejs, 3 dots: ... , after cancel using ctrl-c. i start node.js following command: nodejs , not node . using --harmony doesn't make difference. node.js version: v0.10.25 why don't result back? thought using nodejs commandline test utility, maybe not idea? the simple answer why returns false because though functions same thing , same, initialized in 2 different memory locations (for objects functions, plain objects, , arrays, strict equality operator === checks memory location of object.) also, if you're going use node.js, have make sure interpreting ecmascript6 (otherwise, () => 0 not valid es5, default node.js). you can use --harmony flag: node --harmony app.js see question "what node --harmony do?" more info using es6 in node.js. brief quote top answer: it seems harmony
