May 21st, 2015 admin

This is the command in bash that you would need to list the folders and subfolders of a directory in order of file size. This is useful because you may need to know in what directory you have bigger files – for example when trying to delete old big emails.

Search / Find files modified in the last x days with Bash in Terminal

March 13th, 2015 admin

So, if you are like me, sometimes for any number of reasons, you have to find all the files of a certain type that have been modified lately. For example, if a client had a security problem with their website and you would like to check what files where modified since the last backup.

Setup a Git Repository in your VPS

November 6th, 2012 admin

So I am pretty new to the whole version control scene. Therefore, I wanted to jump in the wagon with both feet and really start using GIT. The problem was that it is not as easy as people make it sound. I was confused with figuring out what a repository meant, what pushing, clone and all sorts of problems that a beginner may have. And the problem is that the documentation available is also a bit technical and difficult to read. That’s why I wanted to explain it here. Now, my personal challenge was that since I have access to a VPS via SSH, I didn’t want to necessarily pay for a private repository if I didn’t have to. And since I was beginning to use git, I really didn’t need a great account with Github or something along those lines.

The other challenge is that I wanted my repository to be available everywhere but also to be private to me. I wanted to be the only one to access it. The reason is that sometimes I am out of the country, and I would love to be able to simplify the process of working remotely in projects and keeping them on a VPS repository.

September 24th, 2012 admin

Sometimes you may run into a situation where a Mailman mailing list is keeping either public or private archives of your messages and therefore you’ll eventually run into an interesting problem:

Problem:

Because Mailman has been keeping an archive of every message, image and email content that has been used in the list, that means that eventually that archive will be enormous, or at least big enough to make you want to delete it. How do you go about doing that? You can spend hours trying to find the right answer in Google and testing what works and what doesn’t or you can bypass all that and jump into the answer! Here it is:
