i have table contains information users post messages website. table named logs , has following records: id, epoch, username, msg (epoch unix epoch of when posted, msg message posted) i have decided divide day 4 segments, 6 hours each (0-5, 6-11, 12-17, 18-23). i want determine percentage of posts user makes during each of these segments. is there nice way can 1 sql query? take forever if had make 4 queries below per username. select count( num ) `logs` username = 'bob' , from_unixtime( epoch ) between date_sub( now( ) , interval 1 week ) , now( ) , hour( from_unixtime( epoch ) ) between 0 , 5 the above query tells me how many posts bob has made between hours 0 , 5, past week. feels horribly inefficient, because better if query load of bobs posts, data need, , return that; instead of having load posts 5 different times (#1 total posts, #2/3/4/5 posts during specific hour range) my goal posts bob has made in 1 query, divided different times of day (i.e. bet

our client user table separated other tables "security reasons". practice given our application built using ror , mysql , running on unicorn , nginx ? i can think of 2 possible ways: create 2 different login accounts, 1 user table , 1 other tables. or have separate database user data. i think both solutions might create problems migrations , other tasks , don't know if effective method of protecting user data. junior developer , not familiar database , security concepts. suggestion? a common pattern have users table literally contain details of user account , no details of actual person behind account. ie, have username, email, password, or encrypted password & salt or whatever, nothing else - not name. so, "glue" makes system work stays in users table in regular database. then, details of real person behind account (name, telephone number, address, card details etc etc) stored in different table, or tables, foreign key in eith

after nighter enough caffeine kill small rhino, got parse push notifications working realize not act expected. the notifications sent, , received in didreceiveremotenotification not acting coded. out of 5 test notifications sent, 2 worked perfectly. rest of time notification still appeared in notification center not interact didreceiveremotenotification. since did work few times, i'm not sure code post since i'm assuming code in appdelegate fine. , certificates/ plist/ provisional profile must set correctly since notification alert comes through time. so guess i'm wondering if there possible problems cause notifications work differently. if application.applicationstate != uiapplicationstate.background { // track app open here if launch push, unless // "content_available" used trigger background push (introduced in ios 7). // in case, skip tracking here avoid double counting app-open. let prebackgroundpush = !ap

i need access isolate scope of directive in order test functions contains. have tried solutions found so. problem in isolate scope of directive, because if don't set directive isolate scope, tests work fine. my directive looks this: angular.module('validators').directive('validatename', [function() { var directive = {}; directive.restrict = "a"; directive.require = 'ngmodel'; directive.scope = {}; directive.link = function(scope, element, attrs, ngmodel) { scope.checkifgoodcharactersonly = function(name) { if ( name.match(/[0-9!$%^&*@#()_+|~=`{}\[\]:";'<>?,.\/]/g) ) { return false; } else { return true; } }; }; return directive; }]); the testing set-up looks this: beforeeach(module('validators')); describe('directive: validatename', function () { var $scope, elem;

i'm trying create sql groups 3 columns , gets count of rows form grouped result. also, ordered highest count, first. i've created sqlfiddle me. table schema (simplified): create table [dbo].[foo] ( [fooid] [int] identity(1,1) not null, [createdon] [datetime] not null, [company] [varchar](20) not null, [productfirstname] [varchar](100) not null, [productlastname] [varchar](100) not null ) sample data: insert foo values ('2001-10-01t07:07:07', 'red', 'yummy', 'gummybear'); insert foo values ('2002-10-01t07:07:07', 'red', 'yummy', 'gummybear'); insert foo values ('2003-10-01t07:07:07', 'red', 'bannana', 'cake'); insert foo values ('2003-11-11t07:07:07', 'red', 'green', 'apples'); insert foo values ('2004-10-01t07:07:07', 'red', 'yummy', 'gummybear'); insert foo values ('2005-10-01t0

i use php (lessphp) compile less files css files on serverside. pass variable less file, color or language: compile('input.less?lang=en') and use variable in less @lang. is possible? if not, there workarounds? this built in feature of lessphp , here's documentation: http://leafo.net/lessphp/docs/#setting_variables_from_php

this question has answer here: why (1 in [1,0] == true) evaluate false? [duplicate] 1 answer why these statements work expected when brackets used: >>> (true false) == false true >>> true (false == false) true but returns false when there no brackets? >>> true false == false false based on python documentation operator precedence : note comparisons, membership tests, , identity tests, have same precedence , have left-to-right chaining feature described in comparisons section. so have chained statement following : >>> (true false) , (false==false) false you can assume central object shared between 2 operations , other objects (false in case). and note true comparisons, including membership tests , identity tests operations following operands : in, not in, is, not, <, <=, >, >=, !=, ==

the following code reads file containing value represents length of more following data. auto file = std::ifstream(filename, std::ios::in | std::ios::binary); // datalen = read header field containing length of following data. std::vector<unsigned char> data; data.resize(datalen); file.read((char*)data.data(), datalen); it fails msvc 2013 compiler if datalen = 0 . causes abort message expression: invalid null pointer , because data.data() returns null pointer. this question suggests count of 0 valid std::basic_istream::read , third comment on question seems point out issue. is valid c++ pass invalid pointer std::basic_istream::read (or std::basic_ostream::write ) size of 0? seem logical me, because call should not touch buffer anyway. the obvious solution deal special case if clause, wondering if msvc wrong once again. here compiled example of clang running program fine: http://coliru.stacked-crooked.com/a/c036ec31abd80f22 here standard says std::basi
