Configure sSMTP or Postfix to send email via SendGrid on CentOS 6.3 ec2

I often launch CentOS images on ec2, specifically the RightImage_CentOS_6.3_x64_v5.8.8.5_EBS (ami-3b7bfc52). It’s a great clean CentOS image if you need to run tests or install Kaltura on a clean machine. A common requirement is to have an email sending service, preferably postfix that will be stable and handle long queues of emails (to support for email notifications or alerts). According to this thread on the AWS forums, mainly to block spam, ec2 servers are by default blocked from Read more...


Kaltura Knowledge Center Search IRC Bot Module

We spend a good amount of time on our #kaltura freenode channel during the day, staying in touch with other community developers, assisting others or simply chatting in a more collaborative environment than Skype… This weekend I decided it’s time to retire our old PHP based IRC bot (bit of server cleanup), and replace it with a newer more maintained bot… A quick search and playing with several bots around including two PHP based bots (@,@), a node.js one and two python Read more...


Fast, Recursive And Literal Search Across All Files In A Folder (Grep / Find)

I’ll just put here for future reference: This grep will search recursively across all files in a given path. dcf8520ee6fe1a978d26c0a91e23f829012 Notes: Replace the dot at the end with the top-folder to search in. Remove the lower case ‘i’ to make the search case-sensitive. Remove F if searchterm is a regular expression. Shout-out: How to use “grep” command to find text including subdirectories To run a search only for folder or file name, use the following. Only Read more...


Hey Mac – I don’t appreciate you spying on me! (Hidden Downloads Log in OS X)

A few months ago I switched to Mac, tired of the back-pain I had from carrying a heavy (and ugly) Lenovo laptop that had 40% the computing power of my current MacBook Air. So lately I’ve been learning the ways of the mac, and being the cygwin user that I was, I felt at home with the OS X’s Terminal (I use iTerm). Interesting things that you find while cruising the web searching for OS X tips and tricks. Today, I came across this post from OSXDaily discussing a Mac OS X (10.5+) Read more...


Install SSL on Ubuntu and Enable HTTPS

Lotts docs out there, some are better than others, but most are a bit confusing. Just dropping this here for potential future need… The 2 best I came across are: http://www.akadia.com/services/ssh_test_certificate.html http://www.tc.umn.edu/~brams006/selfsign_ubuntu.html/ I found that steps 1-4 in the first guide are easy to follow and will work well to generate your keys. Then follow the second guide to enable SSL on your Apache and set things up. For easier review: Step 0: Install Read more...


Build and Install FFMPEG and x264 on Debian Squeeze – The Dumb Guide

That took some time to figure out… I’ve tried at least 6 different articles from the top Google results, none worked and most were outdated. Anyways, no commitment here either, it worked for me, but I’m no Debian expert.. so use at your own risk. First – Add the new multimedia packages - dcf8520ee6fe1a978d26c0a91e23f829039 Add the following lines: dcf8520ee6fe1a978d26c0a91e23f829040 Install all the dependancies and build tools Read more...


Dump RTMP Video to a File

Often (or not) you might come across the need to download a video from a site you don’t own (e.g. someone uploaded an interview of you), but they use an RTMP server to stream their video. This neat tool will go to the URL of the page hosting the video player, load the page in a mini-browser screen, wait till you click play and… dump the video to a file. RTMPExplorer. Based on RTMPdump (and you’ll actually need to download RTMPdump to the same folder of RTMPExplorer to make Read more...
