My first C program: now and then

I was searching for some documents in gmail and found a mail that I sent to company X for their hiring process. It was a c program for searching word in file. I do not know how much time I have taken for it but it was basic search utility function.

The point of this blog is not discuss that program but to discuss how time makes you better programmer.

Here are the few things I would like to share myself -

  • It takes some learning to write clean code. 
  • Reed books like clean code.
  • You need mentor to learn from his experience.
  • Get a github account and see how experts are writing code.
This is not the complete list, there are many things you will acquire over a period of time which make you better programmer.

PS: If you are wondering how that program used to look like, then see this repo.

GlassFish V3 admin console taking too much time to load.

If you have installed Glassfish V3 and trying to load admin console, but after signing in, is it taking too much time to get to the main page ? Do you have server.log entry like this: admin console: initSessionAttributes() Cannot refresh Catalog : Connection timed out then its time to tweak some files. Here its how: 1. Update the %GLASSFISH_HOME/glassfish/domains/domain1/domain.xml -Dcom.sun.enterprise.tools.admingui.NO_NETWORK=true This will block up the News item, the registration item, etc 2. Remove update tool jar (Backup and remove this JAR) %GLASSFISH_HOME/glassfish/modules/console-updatecenter-plugin.jar Delete this dir: %GLASSFISH_HOME/glassfish/domains/domain1/osgi-cache %GLASSFISH_HOME/glassfish/domains/domain1/generated Now start the server (bin/asadmin start-domain) and you will see the admin console won't be hang up and take you directly to main page.

INTO OUTFILE query, How to modify & output null values ?

I tried one query (originally asked at JR) on MySQL which export the table data into a file, with a comma delimited field. The query is straight forward and replace the null column value by "\N" character, but when I want to replace that "\N" value by some other character like "0" or simple empty field like " ", its gets little tricky. Here is the base query SELECT Id, name, age FROM student INTO OUTFILE 'c:/result.txt' FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\n'; And it outputs like, 1, "sagar", 23 2, "anant", 24 Now suppose some 'name' fields are null, then it outputs like 1, "sagar", 23 2, \N, 24 Now to obtain my desired results, which replace this null (\N) values by empty string like, "", I tried out two solutions --1. Using CASE statement SELECT Id, CASE WHEN name IS NULL THEN '' ELSE name END AS NewName, age FROM s...
