i set myisam table fulltext searching. do not want searches case-sensitive. my searches along lines of: select * search match (keywords) against ('+diversity +kitten' in boolean mode); let's keywords field i'm looking has value "my diversity kitten". i noticed searches case-sensitive. double-checked collation on search table, set utf8_bin . d'oh! changed utf8_general_ci . but query still case-sensitive! why? is there server setting need change, too? is there need besides change collation? i did "repair table search quick" rebuild fulltext index, didn't either... my searches still case-sensitive. =( aha, figured out reals time. i believe issue using navicat update collation. have older version of navicat, maybe bug or something. doing: alter table search convert character set utf8 collate utf8_general_ci; fixed correctly. always use command line, kids! =)

i have class want put factory methods on spit out new instance based on 1 of 2 construction methods: either can constructed data in memory, or data stored in file. what encapsulate logic of how construction performed inside class, have static class methods set this: class myappmodel def initialize #absolutely nothing here - instances not constructed externally myappmodel.new end def self.construct_from_some_other_object otherobject inst = myappmodel.new inst.instance_variable_set("@some_non_published_var", otherobject.foo) return inst end def self.construct_from_file file inst = myappmodel.new inst.instance_variable_set("@some_non_published_var", get_it_from_file(file)) return inst end end is there no way set @some_private_var on instance of class class without resorting metaprogramming (instance_variable_set)? seems pattern not esoteric require meta-poking variables instance

in quest update core data model within ios project, i'm querying server json objects correspond - extent - managed entities of model. end result i'm striving reliable update solution json output. for examples in question, i'll name core data managed object existingobj , incoming json deserialized dictionary updatedict . tricky part dealing these facts: not properties of existingobj present in updatedict not properties of updatedict available in extistingobj . not types of existingobj 's properties match json deserialized properties. (some strings may need custom objective-c wrapper). updatedict may contain values keys uninitialized ( nil ) in existingobj . this means while iterating through updated dictionaries, there has testing of properties , forth. first have test whether properties of updatedict exist in existingobj , set value using kvc, so: // key nsstring, e.g. @"displayname" if ([existingobj respondstoselector:nsselectorfromstrin

i have been asked performance issue of sql server installation. not sql server expert, decided take look. using closed source application appears work ok. after sql server upgrade 2000 2005, application performance has reportedly suffered considerably. ran sql profiler , caught following query (field names changed protect innocent) taking 30 seconds run. first thought should optimize query. not possible, given application closed source , vendor not helpful. left, trying figure out how make query run fast without changing it. not clear me how query ran faster on older sql server 2000 product. perhaps there sort of performance tuning applied on instance did not carry on or not work on new sql server. dbcc pintable comes mind. anyway, here offending query: select min(row_id) table1 calendar_id = 'test1' , exists (select id table1 calendar_id = 'test1' , datediff(day, '12/30/2010 09:21', start_datetime) = 0 ) , exists (sel

i have mysql database column named dateadded. i'd echo readable date/time. here simplified version of code have: $result = mysql_query(" select listitem, dateadded lists userid = '" . $currentid . "' "); while($row = mysql_fetch_array($result)) { // make date nicer $dateadded = date('d-m-y',$row['dateadded']); echo $row['listitem'] . ","; echo $dateadded; echo "<br />"; } is use of date function best way output user-friendly date? thanks taking look, if don't plan on outputting dates beyond 2038, fine using date() . otherwise, use php's datetime doesn't have limitation, or mysql's date formatting functions format date directly in database. however, seem storing timestamp in database. have considered switching datetime field?

so, reasonably competent web development shop, wear cotton gloves when touch credit cards, , use braintree securevault store them clear of pci compliance issues. however want offer free trial our service, pretty relies on being able guarantee given credit card used once free trial. ideally able hash credit card number guarantee uniqueness. problem there set of valid credit card numbers small, it's going easy brute force credit card numbers. salting tactics useless far can see, because if has access database of hashes, have code well, , salting algorithm. the best 2 ideas far are: a) keeping hashes isolated in set, no relation billing information. therefore if hashes brute-forced, have list of credit card numbers used @ point in time, no personal information or knowledge of whether it's still valid. main weakness here have record of last-4 potentially used match them extent. b) hash without full number , deal false positives , negatives. hashing on name, last-4
