Best Google Chrome Extensions

He we go. I though of compiling a list of the best / top Google Chrome Extension that save me hours upon hours of work. I don’t know if you are like me but every time I encounter the famous 20 second limit before doing anything, I seriously reconsider the idea of starting which push me to procrastinate often. The solution? I just need to make sure that when I need to do something, I can start in less than 20 seconds. Here comes the life savers extensions from Google Chrome. The list:


The perfect extension to share interesting web pages on all you social profiles. Facebook page, Twitter and LinkedIn. Being a business operator, I actually have to manage more than 12 social accounts which make the extension Bufferapp a must. It also allow me to just publish my articles and the app will make sure to release them when the best time come. Example: Its midnight and I decide to publish a few articles. I just need to put them in Bufferapp and they’ll take care of sending them to Twitter and Facebook at the most appropriate times. 9pm, 2pm, etc.

Checker Plus for Gmail

This is one of my favourite tool. I no longer need to login to and check if I received new emails. While surfing, Checker Plus will simply notify me of new emails and ask me if I want to “Read”, “Archive” or “Delete” them. I realized after a month of intense use that it really reduce the time I pass in my inbox because it force me to take immediate action which is perfect for me. If you are the kind of person that check you email only 2 times a day, like Tim Ferriss, you can simply configure the app to check every few hours. By default mine is set to 15 minutes.

Facebook Notifications

Forget about logging in to Facebook, just use Facebook Notifications to get the infos you need. While listening to a Youtube video, I can actually read my Facebook notifications at the same time. You also have the ability to comment or like any article of your friends. The extension doesn’t replace the website but it pretty well come close to it.

Notifier for Twitter

Rapidly access your twitter account to see, mentions, direct message and twitter feed. You also have the ability to respond and post directly from the extension. Enjoy. It is a perfect replication of twitter. I don’t even bother going to anymore with this app.

Extensions that deserve a mention

  • Adblock: With more than 40 millions users, it is one of the most popular app in the world. It basicly make the web a ad-free space. I just love it.
  • Client for Google Analytics: In one click, see all the stats of every websites you added to Google Analytics! AWESOME

  • Rapportive: In Gmail, just point your cursor on the email of the person you want to check out and rapportive will automatically show you their corresponding Twitter, Facebook and LinkedIn account. Its always nice to know the person behind the email. Perfect for salespeople.

How to install and configure fail2ban

What’s Fail2ban

While connecting to your server through SSH can be very secure, the SSH daemon itself is a service that must be exposed to the internet to function properly. If you pay attention to application logs for these services, you will often see repeated, systematic login attempts that represent brute force attacks by users and bots alike.

A service called fail2ban can mitigate this problem by creating rules that can automatically alter your firewall configuration based on a predefined number of unsuccessful login attempts. This will allow your server to respond to illegitimate access attempts without intervention from you.

Fail2ban is very easy to set up, and is a great way to protect any kind of service that uses authentication.

Install Fail2ban

Because fail2ban is not available from CentOS, we should start by downloading the EPEL repository. Connect to your server with SSH and enter the following commands:

rpm -Uvh

From this moment on, I will assume that you are connected as the root user. If you are not, use the command sudo…

yum install fail2ban -y

As you can see, the installation is trivial. We can now begin configuring the utility for our own use.

Configure Fail2Ban

It is necessary to edit fail2ban only if you desire to receive daily email log. Otherwise, just go and restart the service.

nano /etc/fail2ban/jail.conf

To receive daily email log from fail2ban, just replace “” with your email in the following lines.


enabled = true
filter = sshd
action = iptables[name=SSH, port=ssh, protocol=tcp]
sendmail-whois[name=SSH,, sender=fail2ban@examp$
logpath = /var/log/secure
maxretry = 5

By default, the SSH service is enabled and all others are disabled.

When you are finished, save and close the file.

Finish it up

Now, start or restart your fail2ban service. Sometimes, it’s better to completely shut down the service and then start it again:

service fail2ban restart
Idea Validation

Will that brilliant business idea really take off? Here are ways to test it–before you invest too much time and money.

1. Run a basic Craigslist/Kijiji ad to gauge interest

For example, perhaps you want to start a business around hiring babysitters online. First, place an ad that offers the services. Do people contact you? Backpage, Oodle, OLX

2. Facebook Ads + LaunchRock

Travis Steffan, a serial entrepreneur, says he generally places an idea on a site like LaunchRock, which helps people to quickly set up a “Launching Soon” page. He then invests in Facebook ads and watches click-through rates. If a good number of people sign up, it means there’s real interest, and it’s time to take the next step. Google Ads, StumbleUpon, Reddit

3. Ask yourself if the product is something you would use

4. Take a piece of paper, and write out the names of 5 people that need your product.

Just 5 people. This is an effective test, because it makes it real. If you built this thing, who would buy it? Can’t think of 5 people? That’s a red flag. Are you targeting a product at a group of people you don’t yet have a connection with?

5. Email 10 people you know who would want your pseudo-product

Email 10 people you know who would want your pseudo-product, then ask them to send payment via Paypal. This might sound a bit crazy, but you’re doing it to see what the overall response is like. If a few of them send payment, great! You now have validation and can build the product (or you can refund your friends and buy them all tacos for playing along). If they don’t bite, figure out why they don’t want your product. Again, the goal is to get validation for your product, not to rip off your friends.
