Debian install MailUtils needs configuration of Exim

When you first install MailUtils on Debian

apt-get install mailutils

The system will not send emails.

To test it:

echo "This is the body of the email" | mail -s "This is the subject line"

and have a look at the logs:

cat /var/mail/mail

To fix this, it is needed to configure Exim:

dpkg-reconfigure exim4-config

You will be presented with a setup wizard of something like this:

The settings are pretty straight forward but you can just leave them with Internet Site and type your domain. The rest should work with the default settings.

Why nobody likes your Facebook Page

I see plenty of companies starting Facebook Pages and not knowing what to do with them. I think the main problem is with the lack of information on how Facebook treats pages (and profiles but that is a different story).

You just need to look at stats of Facebook Pages for October 2015 to understand what is going on:

  • Likes Growth: 0.20%
  • Post Reach: 7.25%
  • Engagement: 5.87%


Meaning, during October of 2015 for a page with 1000 likes, only 2 new likes were obtained, each post only was viewed by 73 persons and from that 73 only 4 engaged with the post (like, comment, click).

So, if you post once a week on a page with 1000 likes, you can expect 16 people to engage with your posts.

Obviously this is an average and you can (and should) get better results if you post great content for your audience. But don’t expect miracles. Getting a Facebook Page to be a good return on investment (ROI) is hard work.

I like to listen and learn with Gary Vaynerchuk. I don’t agree with some things he says but I think is a smart guy. He famously asks: What is the ROI of your mother? and he has got a good point. You cannot know the ROI of a social media presence upfront. You need to invest, try, adapt, learn, see what works and your ROI.

So, let’s be real: most Facebook Pages suck and nobody REALLY likes them. Your page probably sucks too. How many pages on Facebook do you engage with? Your users are not so different from you.

If you have a Facebook Page or are thinking of creating one, there are only two ways to go about it:

  • do it casually (post once a week) and expect little from it
  • do it properly, invest daily into creating great content for your audience and test what works best (as a rule of thumb: videos have a higher reach, photos a higher engagement)

I believe that anything in between will be a waste of time and the ROI will be negative.

Adding Placeholder attribute to Tokeninput jQuery plugin

I was having a hard time to get the placeholder attribute to work with Tokeninput jQuery plugin.

First I managed to get it to show up by adding attr(‘placeholder’) to the onReady:
onReady: function(){ $('#token-input-myInput').attr('placeholder','type here...'); }

It worked but every time it lost focus the resize of the input field would partially hide it. So, I tweaked with the code inside jquery.tokeninput.js and after line 436 (declaration of var escaped) added:
escaped = input_box.attr('placeholder');

It is not pretty but it works 🙂

Another example of why you should never use WordPress as an MVC for a major site

Zootool is a cool visual bookmarking site.

Zootool homepage

They have been fairly sucessful:

They posted on on the 17th that they have been hacked.

The site is still down for registration and not sure how useful it is at the moment:

zootool hacked message

Eight days down, and still counting, is not acceptable. Not for a professional website.

WordPress both .com and .org are amazing MVC for blogging. Period. Nothing else. If you want to write a magazine, post content or solely blog. You can’t go wrong using Worpress. If you want to build a tool or a web app. Forget it! Not the way to do it! Anyone that tells you otherwise, they don’t know what they are talking about.
