the backstory: this works fine in browsers except safari (5.0.1) var chunk = arr[i]; chunk = chunk.replace('$', '\\$'); var = eval('message.match(/' + chunk + '/gi);'); if(a instanceof array) symbol = symbol.concat(a); so modified following: var chunk = string(arr[i]); chunk = chunk.replace('$', '\\$'); var = eval('message.match(/' + chunk + '/gi);'); if(a instanceof array) symbol = symbol.concat(a); which made safari bit more happy throwing ambiguous error (fun!) i've found solution , i'm posting below in case other fellow scripters run problem. i couldn't reproduce problem because i'm not sure what's value of chunk . anyway, 1 more example of unnecessary usage of eval , can use regexp constructor build regexp object string, example: var re = /foo/gi; is equivalent creating object in runtime regexp constructor: var re = new regexp('foo', 'gi'); appl...

i have following structure: table: products id, name, sort_order let's have 5 products, want 20. how loop through 20 results? additionally, i'll need start @ specific sort_order. let's have 1,2,3,4,5 and want 20 results , start @ 3. should end as: 3,4,5,1,2,3,4,5,1,2,3,4,5,1,2,3,4,5,etc. any ideas? i'm totally lost.. thank you! $how_many = 20; $counter = 0; $rows = array(); $result = mysql_query("your query"); while($row == mysql_fetch_row($result)) { $rows[] = $row; } $expanded = array(); for($i = 0; $counter < $how_many; $counter++) { $expanded[] = $rows[$i]; $i++; if($i == count($rows)) { $i = 0; } } and $expanded filled 5 rows 4 times. edit: , don't forget adjust $i start element. example mean $i = 2 (third element).

i want take function out of 1 file , put another, keep blame history. cp a.php b.php vim b.php # delete 1 function vim a.php # delete 1 function git add a.php b.php git commit but if run git blame b.php see blaming new commit. perhaps previous question informative: how git track source code moved between files? to paraphrase accepted answer: essentially, git doesn't "store" moved code; when generating things blames moved code, that's done ex post facto examining state of entire repository commit commit.

i have ##table can accessed across sessions getting error there object named '##table' in database. why , how resolve it. found interesting reference here : global temporary tables operate local temporary tables; created in tempdb , cause less locking , logging permanent tables. however, visible sessions, until creating session goes out of scope (and global ##temp table no longer being referenced other sessions). if 2 different sessions try above code, if first still active, second receive following: server: msg 2714, level 16, state 6, line 1 there object named '##people' in database. i have yet see valid justification use of global ##temp table. if data needs persist multiple users, makes more sense, @ least me, use permanent table. can make global ##temp table more permanent creating in autostart procedure, still fail see how advantageous on permanent table. permanent table, can deny permissions; cannot deny users ...

i apologize if has been asked, how create member function in c++ returns pointer in following scenerios: 1. returned pointer constant, junk inside can modified. 2. junk inside constant returned pointer can modified. 3. neither junk, nor pointer can modified. is so: int *const func() const const int* func() const const int * const func() const all of tutorials i've read don't cover distinction. side note: if method declared const tutorials i'm stating won't modify parameters.. not clear enough me in case when parameter pointer. parameters need like: a. void func(const int* const x) const; b. void func(const int* x) const; c. void func(const int* const x) const; i don't know book have read, if mark method const means this of type const myclass* instead of myclass* , in turn means cannot change nonstatic data members not declared mutable , nor can call non-const methods on this . now return value. 1 . int * const func () const the f...

i learned term "restful" rails developer. after reading wikipedia, here , here . i don't it. seems me, rails using concise way describe urls. seems me every uri restful, in it's designed scope . for example, think get /delete?student_id=3 restful in scope the application itself . can tell me constrict violate? please refer constrict rest definition . a get request should idempotent , request should not leave side-effects on server. quoting http spec sec 9.1.1 : in particular, convention has been established get , head methods should not have significance of taking action other retrieval. these methods ought considered "safe". allows user agents represent other methods, such post , put , delete , in special way, user made aware of fact possibly unsafe action being requested. therefore get /delete?student_id=3 violates idempotency assumption of get verb, since delete record on server. a restful interface uniform interface...

i have 3 tables: actions, messages, likes. defines inheritance, messages , likes actions' childs (specialization). message , both have column userid , createdat. should of course moved parrent table action , removed message , likes. there's 1 case when need select both messages , likes database, in other cases select 1 of them, either messages or likes. is ok duplicate userid , createdat in child , parrent table? costs disk space saves 1 join - have join messages, likes actions everytime needed userid , createdat. whatsmore need change current code... what suggest? in opinion case of premature optimization (or premature denormalization, if prefer). you're guessing join overhead cause significant problems, you're guessing duplicating userid , createdat columns in dependent tables improve performance significantly. i suggest should not duplicate columns until know there's real problem. keep few observations on performance optimization tacked o...

dear forum, difference between jdk contained import com.sun.org.apache.xml.internal.resolver.catalogmanager; and 1 contained in apache xerces project import org.apache.xml.resolver.tools.catalogresolver; are there benefits of using latter simple catalog resolving? read on wikipedia seems clear me there no benefit in using latter: org.apache.xml.resolver.tools.catalogresolver used resolve external entities locally-cached instances. resolver originates apache xerces included sun java runtime. anyway xml related projects qizx supply seperate resolver.jar. help. michael the com.sun.org.apache.xml packages copies of apache projects have been "internalised" jre. you'll find done many of apache xml projects, including xerces , xalan. in 99% of cases, internal 1 fine. reason use org.apache versions if need latest version, bugfix.
