What does @@variable mean in Ruby?
- by Andrew
What are Ruby variables preceded with double at signs (@@)? My understanding of a variable preceded with an at sign is that it is an instance variable, like this in PHP: PHP version class Person { public $name; public function setName($name) { $this->name = $name; } public function getName() { return $this->name; } } Ruby equivalent class Person def set_name(name) @name = name end def get_name() @name end end What does the double at sign @@ mean, and how does it differ from a single at sign?Read the article

MSSQL 2005 Snapshot Agent Uses 100% CPU
- by matth1jd
When setting up a new subscription to a publication (transactional replication) from 64-bit SQL Server 2005 to 64-bit SQL Server 2005 the Snapshot Agent on the publisher consumes 100% of the CPU. I am using SSMS to create the new subscription. My initial impression is that this could be from row locking occurring during the generation of the snapshot but I have read that a concurrent snapshot is generated by default in SQL Server 2005, and that row locking shouldn't be a concern. As this is a production server I would like to be able to initialize replication without bringing the box to it's knees. Any suggestions would be helpful and appreciated.Read the article

SQL & PHP - Which is faster mysql_num_rows() or 'select count()'?
- by Joel
I'm just wondering which method is the most effective if I'm literally just wanting to get the number of rows in a table. $res = mysql_query("SELECT count(*) as `number` FROM `table1`"); $count = mysql_fetch_result($res,0,'number'); or $res = mysql_query("SELECT `ID` FROM `table1`"); $count = mysql_num_rows($res); Anyone done any decent testing on this?Read the article

PHP - if == not working for 0 or ""
- by user2933212
I am checking the validation of the request with an if query, if ($request_userid == $userid) { ... } Thats working as expected. But further testing has shown, that if $request_userid or $userid is 0 or "", then the condition is true and the script runs the if query but it shouldn't. I am currently solving it with: if ($userid == "" ) { exit ("exit"); } But I don't think that this is the right way? Can you explain why it doesn’t work with the if query and what would be the correct way to check it?Read the article

sqlserver.exe uses 100% CPU
- by Markus
I've created an application (asp.net) that once a day syncs an entire database through XML-files. The sync first creates an transaction and then clears the databases tables and then starts to parse and insert the new rows into the database. When all the parsing is complete it commits the transaction. This works fine on a SQL Server 2005 (on another machine), but on SQL Server 2005 Express, the process starts to use 100% CPU after a while, and as I log the inserts being made I can see that it just stops inserting. No exception, it just stops inserting. Anyone got any idea what this may be? I've previously run the syncronization on another sql 2005 express (also on another computer), and that worked. The server has only 2GB RAM, could this be the problem?Read the article
