i have simple sql query want optimize: select * users email = 'jon@gmail.com' i want 1 record matches user's email. is there can make query faster, aside adding index on email column? does adding "limit 1" make faster? what doing order email desc since "j" in alphabet? create index on column email . there no other way make fast. the exact syntax depends on database engine. if email unique (which common users table), make index unique too.

why return 9 plus actual value of answer. example, number 1234, answer 1 yet function returns 10. don't know why case, i'm pretty sure recursion have no idea. int fun(int n) { if (n <= 9) { return n; } else { return fun(n / 10) + (n % 10); } } as makoto stated, it's unclear why believe answer should 1. however, if recursion analysis following: fn(1234) = fn(123) + 4 = 10 fn(123) = fn(12) + 3 = 6 fn(12) = fn(1) + 2 = 3 fn(1) = 1 therefore, using simple substitution, get: fn(1234) = 1 + 2 + 3 + 4 = 10

what's best way write media queries surface pro 3 & 4? in both landscape & portrait views? the best way not write media queries specific devices @ all, rather identify logical places in design fold elements in or break them out accordingly, account devices of width. see article more info: google developers—how choose breakpoints in practice, resolutions of 2 devices mentioned 2160x1440 (surface pro 3) , 2736x1824 (surface pro 4). so, instead of setting 4 breakpoints media queries, 1 logical approach design "greater 2000px", "between 1200px , 2000px", , "under 1200px"—the first rule handling both devices mentioned in landscape mode (also handling common desktop resolutions), second rule handling both devices in portrait mode (and many other common portable devices), , last rule handling devices of sizes under 1200px. this 1 way tackle problem, i'd recommend research more common theories behind responsive design , breakpoin

i have open-sourced math library php , defines own hierarchy of exceptions : arithmeticexception divisionbyzeroexception numberformatexception roundingnecessaryexception now php 7 has landed, realize exceptions feel bit redundant new error classes introduced: arithmeticerror divisionbyzeroerror let's forget php 5 moment , assume library targets php 7. should throw arithmeticerror , drop arithmeticexception ? similarly, should throw divisionbyzeroerror , drop divisionbyzeroexception ? should roundingnecessaryexception , numberformatexception extend arithmeticerror ? in case, should called roundingnecessaryerror , numberformaterror ? at first glance, seems weird redeclare exceptions have native equivalent in language. at same time, , although nothing prevents userland code throwing error , feel these classes designed thrown php itself, , userland libraries better off throwing exception , not error . is there consensus on subject? y

microsoft provides list explaining input , output semantics of vertex , pixel shaders. i've seen code examples don't use documented data types. using float3 input color pixel shader or float2 input position vertex shader. though 2-component position or 3-component color make sense me, can't find documented, makes me wonder can use float3 vertex shader input position (if know won't using w component) without expecting errors? if can use data types other documented ones, there list available shows every allowed data type semantic or rule "as long used data type smaller or equally sized documented one, can use it"? code examples not following documentation: stackoverflow - passing colors through pixel shader in hlsl c++ / directx11 tutorials - s02e05 - creating , loading shaders @ 9:33 in shader model 4.0 , later (dx10+), semantic names matter system-value semantics (those prefixed sv_ ). other semantics have no special treatment

in our professor's example code has 1 snippet looks this: if (name == null || name == "") throw new argumentexception("name null or empty"); and snippet looks this: if (!file.exists(name)) { throw new exception("file not exist!"); } i wondering different , why 1 used above other exception base class exceptions. argumentexception used parameter not valid. subclasses exception . catch , can filter base on type of exception , handle each 1 differently. msdn describes well: when have throw exception, can use existing exception type in .net framework instead of implementing custom exception. should use standard exception type under these 2 conditions: you throwing exception caused usage error (that is, error in program logic made developer calling method). typically, throw exception such argumentexception, argumentnullexception, invalidoperationexception, or notsupportedexception. string supply exception objec
