I am hoarder :).. Esp for free stuff. That’s one of the reason, I have the Amazon Android App Store on my phone. Amazon gives “away” a free app every day. Even though I don’t really use/need the app that Amazon gives away, I get it, just in case. It is free :), so why not?
The apps usually cost something if brought in the regular app store, but Amazon makes them available for free for a day. So yesterday, I was surprised to see a free app appear in the free app of the day section. What gives?
I confess.. I am a nerd :). Pictures of my new office toy. And if you want to make your co-workers jealous, head over to Josh Welton’s site (http://www.browndogwelding.com/) and order yourself a piece of art.
Thx to D for the great pictures..
After a long hiatus :).. here’s a quick update on my 2011 resolutions. In short.. NOT GOOD.. I haven’t made progress (in fact slid back) on any of the pending items.
Thinks look pretty dark eh… Let’s see if we can turn them around. Anyone has ideas on how to stick to the plan?
You know, you are working at a cool company, when one of your favorite podcast mentions it in the show :). Check out the September 19th episode of Tech News Today and Tom speaks about how Gogo is going to improve the speed of in-flight Internet access by 4 times.
BTW.. if you want to work at a company that is changing the industry (of in-flight access and entertainment).. we are hiring :).
I love my “work” to the point that most people that know me think that I am a “workaholic” :). One of the reasons, I love my job is the ability to share my passion for technology. And I know that I am on the right path (despite the long hours), when I receive notes like this (from an ex team-mate)
Hi Vinay,
I hope you are doing great. I would like to take this opportunity to express my thankfulness to you, for introducing us the Modular approach in Perl Scripting during the tenure at TravelClick.
Without your support, I probably wouldn’t have gained confidence to develop script which runs more than 500 lines. Hence I wish to dedicate this script to you.
Btw I started writing a Technical Blog over a year “http://ashok-linux-tips.blogspot.com”. I request you to have a look.
I must admit that the idea of sharing technical solutions via Blog was mainly inspired after seeing your https://kudithipudi.org J
Once again, thanks for all the support extended to us.
Regards
Ashok
Nice job Ashok :).
Quick tip to find out the clients connecting to a NFS server.
[code] grep -i nfs /etc/services [/code]
[code] netstat -an | grep 2049 [/code]
Say you have a directory with a bunch of sub directories and files and you want to see if all the files are owned by a particular user, you can use the following set of commands
[code]ls DIRECTORY_PATH -l -R | awk {‘print $3’} | grep -v USER_NAME[/code]
The set of commands do the following
And yeah.. this works in most variants of Linux :).
One of the largest tech company in the world
Supposedly earns billions in consulting services
and what happens when thousands (and let’s imagine millions) hit their web app store?
More tiers means more tears..
Keep it simple :).
Quick note for future reference..
If you ever run into errors like this
[code]
<pre>Starting httpd: Warning: DocumentRoot [/var/www/html/static] does not exist
Warning: DocumentRoot [/var/www/html/static] does not exist
Warning: DocumentRoot [/var/www/html/static] does not exist
Warning: DocumentRoot [/var/www/html/static] does not exist
(13)Permission denied: httpd: could not open error log file /etc/httpd/logs/error_log.
Unable to open logs
[FAILED]
[/code]
And you are scratching your head why Apache is throwing these errors, even when the said directory and files exist. And you have the right permissions!! Check if you have SELinux running and being enforced.
On RHEL, you can check if SELinux is running by
[code]cat /selinux/enforce [/code]
The two values are 0 and 1. 0 means, SELinux is not being enforced and 1 means it is.
You can quickly disable SELinux temporarily by
[code]echo 0 >/selinux/enforce [/code]
If you want to disable it permanently (i.e. survive reboots), you have to edit the file /etc/selinux/config and change the SELINUX line from enabled to disabled.
