  • How to : Use Google Sets And Squared To Enhance Your Linux Administration Skills


    Long time back we thought of posting this, now the time has come. This post is all about how to use Google's tools "unknown to many" services to enhance your admin skills. I strongly suggest you to use these tools extensively to enhance your knowledge on a given topic. Most of the people will say use google, google is your friend etc. Even some times Google is refered as GOD in IT industry which is acronym to "Google Oriented Development" but they dont tell how to use it. This is one step towards it. OK lets come to what actually this Google Sets and Squired do for us.

    Google sets( :

    Automatically create sets of items from a few examples. This can be easily explained by taking an example. Suppose you know
    How to add user,
    Remove user,
    Modify user details,
    Delete user.. etc. In Linux user management. Now you want to enhance more of your knowledge on this area. So just type below commands in google sets form.

    When you sa grow to “small set” it will create a set of commands/related words up to 15 in number. If this 15 commands is not enough for you enhancing of knowledge you can “grow set”. Once that set is grown you can use that keywords to enhance your knowledge.

    Enter your commands in to this form

    Once you fill the form grow the set(click on small set button)
    Now you can even grow this set.. to more :-)

    Once you grow the set, see how many commands are there in user management it self.

    Google squared( :
    Google Squared takes a category and creates a starter 'square' of information, automatically fetching and organizing facts from across the web. This is more sofesticated with more options. Explore your self how to use google squared to get more out of google :-)

    Home page of google squred where you can enter your data.

    Enter data what you want to square
    This is the output you will get.

    Some of the people still have some confusion right? For those people here are the examples you can try.

    For Google sets :
    1. Try to know what other Linux flavours are there
    Redhat, Centos, Fedorea, Debian, Ubuntu etc

    Do you know there is Linux distribution watching site where you will get up to date Linux flavor?
    Ans :
    Visit the site here :

    2. Try to know what other mail servers exists.
    sendmail, postfix, fetchmail, qmail, procmail etc.

    3. Try to know how many greps are there.
    agrep, egrep, fgrep, grep, pgrep,

    Do you know we have grep song? It starts like this agrep, bgrep, cgrep.... ygrep, zgrep?

    For Google squared:

    1. Try to know more about Raid levels, options, commands, advantages etc.
    RAID0, RAID1, RAID5, RAID6, RAID10 etc.

    2. Try to know more about searching commands.
    grep, find, locate, sed, awk etc.

  • How To Choose A Good Linux Institute?


    This question arises in the mind of new people who are turning to Linux administration. So what you people will suggest? Go for a good institute. Right? So how you judge one institute is good and other is bad? If I am there in your place. I will consider below points before taking a decision to join an institute.
    1. Faculty(first priority)
    2. Infrastructure(second priority)
    3. Institute background and capabilities(Third priority)

    Faculty : Some points be noted about faculty
    1. A good faculty is like a motivator, he always motivates you to explore new things. He just shows the path you have to explore.
    2. A good faculty always try to share knowledge irrespective of the domain. I saw some instructors will not share all the knowledge they have. They just simply go according to the syllabus. So be aware of these type of instructors.
    3. A good faculty will always try to mould his way of teaching depending on grasping power of the students.
    4. A good faculty always give infomation about what type questions will come in interviews and exam. So that you can concentrate more on those topics.

    So how to judge a faculty is good or not with out actually attending his classes?
    Ans : Just go to that institute before joining and enquire the students of that institute about the instructors and their way of teaching. And if possible take a sample session with that faculty and observe all the above mentioned points. If most of the above qualities are not observed better not to join.

    Infrastructure :
    Some points to be noted about infrastructure
    1. As we are learning job oriented courses please don't join in institutes where students with more than 30 per class. These type of institutes are more in Hyderabad. One thing i want to mention is if a class is containing some 150 students where is the type for faculty to care of your queries?

    2. Make sure that before joining the institute about the hardware provided by them. In some institute there will be only one or two systems/devices per class so where is the time for you to practice? right so consider this one too.

    3. Some institutes will not provide lab facility after the class timings. So what's the fun of just taking Linux classless with out practice. I say to my friends if you want to be a good Linux admin just remember three rules/principles.

    So what is ideal Infrastructure?
    Ans : A class should not contain more then 10 to 15 students and should provide at least one system for two students with 24 hours lab facility.

    Institute : Some points to be noted about Institute.
    1. Check with Students of an institute about the behaviour of non teaching faculty. Some of the institute people will behave differently before and after paying amount.

    2.Check with students how is the placements and campus interviews.

    3. As you people will know speaking good English will play important role in getting a job, some institutes will have one faculty who will teaches spoken English, corporate culture, personality development etc.

    So you guys may feel that as "I am already a Linux admin why this non technical post is here." this is for you only. As you are an experienced Linux admin, many new comers will come to you and ask which institute is best. So at that time you can express your own ideas and these points to them before they take a decision. This is the intention of this post.

    Please comment your experience either its small or big about your training institute where you learnt some admin courses:-)
