the db working in stores date values int . needing determine date difference between 2 date fields unsure how approach since int . dates stored follows: 20130101 - yyyyddmm . performing datediff results in arithmetic overflow error. any ideas on how either convert 2 date fields or find date difference between them? select cast( cast( 20130101 varchar(8) ) datetime ) so, if have following 2 values: 20130101 , 20130201 , might following: select datediff( d , cast( cast( 20130101 varchar(8) ) datetime ) , cast( cast( 20130201 varchar(8) ) datetime ) ) update if have values less 17530101 (the min value datetime), need use case expression validate data processed. in scenario, use of cast(0 datetime) result in 1900-01-01 our minimum date value. select datediff( d , case when value1 <= 19000101 cast(0 datetime) else cast( cast( value1 varchar(8) ) datetime ) end , case when value2 <= 19000101 cast(0 date

i writing login forum, , need hash password client side in javascript before sending on server. i'm having trouble figuring out sha-256 implementation can trust. expecting there kind of authoritative script used, i'm finding loads of different projects own implementations. i realize using other people's crypto leap of faith unless you're qualified review yourself, , there no universal definition of "trustworthy", seems common , important enough there ought kind of consensus on use. naive? edit since comes lot in comments: yes, more stringent hash again on server side. client side hashing not final result save in database. client side hashing because human client requests it. have not given specific reason why, overkill. the stanford js crypto library contains implementation of sha-256. while crypto in js isn't well-vetted endeavor other implementation platforms, 1 @ least partially developed by, , extent sponsored by, dan boneh , well-est

let's want execute arbitrary mov instruction. can write following function (using gcc inline assembly): void mov_value_to_eax() { asm volatile("movl %0, %%eax"::"m"(function_parameter):"%eax"); // move value of variable function_parameter register eax } and can make functions 1 work on every possible register. mean - void movl_value_to_ebx() { asm volatile("movl %0, %%ebx"::"m"(function_parameter):"%ebx"); } void movl_value_to_ecx() { asm volatile("movl %0, %%ecx"::"m"(function_parameter):"%ecx"); } ... in similar way can write functions move memory in arbitrary addresses specific registers, , specific registers arbitrary addresses in memory. ( mov eax, [memory_address] , mov [memory_address] ,eax) now, can perform these basic instructions whenever want, can create other instructions. example, move register register: function_parameter = 0x028fc; mov_eax_to_memory();
