i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.

this interesting topic , use following formula compute access interval time: breakevenintervalinseconds = (pagespermbofram / accessespersecondperdisk) × (priceperdiskdrive / pricepermbofram). it derived using formulas cost of ram hold page in buffer pool , the cost of (fractional) disk perform i/o every time page needed , equating these 2 costs, , solving equation interval between accesses. so cost of disc i/o per access priceperdiskdrive / accessespersecondperdisk , question why disc i/o cost per access computed this? the underlying assumption limit life of disk how many disk seeks there are, while ram has fixed cost size, , fixed lifetime regardless of how accessed. reasonable because seeking disk causes physical wear , tear, , when disk goes, lose whole disk. contrast ram has no physical moving parts, , not wear out use. with assumption, cost of keeping data on disk depends on frequency of access , cost of disk. cost of keeping data in ram depends on how ram...

public class { private static final int x; public a() { x = 5; } } final means variable can assigned once (in constructor). static means it's class instance. i can't see why prohibited. keywords interfere each other? a constructor called each time instance of class created. thus, above code means value of x re-initialized each time instance created. because variable declared final (and static), can this class { private static final int x; static { x = 5; } } but, if remove static, allowed this: class { private final int x; public a() { x = 5; } } or this: class { private final int x; { x = 5; } }

say have file a.php contains large array: $client = array( "a" => 123, "b" => 124, ... ); apc caches file a.php mean exactly? caches opcode assignment only? cache mapping itself? or need explicitly put in apc cache? thanks! apc caches php file in byte code. faster intermediary between human readable code , interpreter ends executing. analogous compiling c/c++ file binary. array compiled in fashion load quicker if read form file. accessing element in associative array in php constant time o(1) in big-o . adding element o(1). , large best store such arrays in database because uses less memory , more flexible. keep in mind every browser visits application going have own copy of array, if use database there 1 copy. instance if want key based on value you'll have iterate on o(n) (which slow), use of database faster.

how use if statement inside of jquery template? here's template: <script type="text/html" id="attachmentlisttemplate"> {{if $item.current_cmt_id == id }} <li> <a href="${link}" class="fancyiframe clearfix">${title}</a> </li> {{/if}} </script> where id ${id} , being passed data binding (via knockoutjs). without if statement outputs fine, so: ${$item.current_cmt_id} here data-binding (powered knockoutjs): <ul data-bind='template: { name: "attachmentlisttemplate", foreach: attachmentsmodel.convattachments, templateoptions: {current_cmt_id: <%=comment.id%>} }'> </ul> any suggestions why if sttatement not working? comparing 2 conditions correctly? assuming id observable, need invoke function rather treat property. try following: {{if $item.current_cmt_id == id()}}
