How to Fail at almost Everything & Still Win Big
How to Fail at almost Everything but still Win Big by Scott Adams (affiliate link) comes up on Hackers’ News a lot. Finally, I had a chance to read it.
This is a little different kind of book compared to my regular reads about ultra-successful business titans. I had no idea who Scott Adams was until I heard about this book. He created Dilbert comic. He gave very down to earth perspective on how he achieved success in this book.

OpenShift Error: Layer 7 Wrong Status, Invalid Response
I have been playing with OpenShift for past several hours. It looks great. But a while back I started to get 503 Internal Server error.
When I checked logs using rhc tail , I saw this error: Layer 7 Wrong Status, Invalid Response 404.
I spent an hour or so troubleshooting. Turns out the issue was Netbeans had added src/main/web/app/WEB-INF/jboss-web.xml when I ran the application locally on my machine. I committed this file, thinking I might need it. Deleting it from repo fixed the issue.

4 Hour Body by Tim Ferris
Slow Motion Workout
The technical term is 5/5 Cadence (5 seconds up, 5 seconds down). I tried this for the first time on Sunday, it is really intense. Momentum is not there to help you. You will feel every part of your muscle throughout the motion.
Weights
Tim Ferris showed a simple formula to figure out what should be the starting weight to workout with. Simply do regular sets. If you can do 5 rep, wait a minute & then increase the weight by 10 lb or 10%. When you fail a set, then take 70% of last 5 rep set and use that weight for slow motion workout. You can figure out weights to use by trial and error. This should prevent injuries or wasted time.
…MySQL Update If Exist Else Insert Procedure
Are you tired of checking data in your code before inserting? Well MySQL procedures are here to rescue. This simple procedure shows how you can do that:
CREATE PROCEDURE ` update_insert_user ` ( IN uid2 int )
BEGIN
DECLARE last_login2 DATETIME;
SELECT ` last_login ` INTO last_login2 FROM ` user ` WHERE ` uid ` = uid2 LIMIT 1 ;
IF last_login2 IS NULL THEN
INSERT INTO ` user ` ( ` uid ` , ` last_login ` ) values (uid2, now());
ELSE
UPDATE ` user ` SET ` last_login ` = now() WHERE ` uid ` = uid2 LIMIT 1 ;
END IF ;
END
Codeigniter Creates a New Session With Each Page Load
Just spent 3 hours debugging a session bug in my webapp. CodeIginter was creating a brand new session with each page load. The issue was a misconfiguration with my config file.
Fix was simple, in /application/config/config.php, make sure correct domain is set for $config['cookie_domain'].
Codeigniter Out of Memory Error
Query Saving is a feature of CI’s database class that stores the results of every query in memory until the controller is finished executing. As it turns out, in version 1.6.0, the ability to turn this off was added. The addition of the save_queries variable is listed in the Change Log, but as of the latest release of 2.0.0 last week, it still hasn’t made the documentation.
$this->db->save_queries = FALSE;

ssh_exchange_identification: Connection closed by remote host
I tried to login to my server tonight but kept getting following error message:
ssh_exchange_identification: Connection closed by remote host
The fix was simple, at least if you have access to server via cPanel. Just restart sshd service via cPanel/WHM.
