The era of HTTPS SSL encryption

On the first day of year 2016, I transferred all my websites from HTTP to HTTPS SSL. As you see, now all URLs of this site start with HTTPS instead of the past HTTP. These websites are the follows:

  1. https://www.cementscience.com the world of cement science.
  2. https://www.xiangweiqing.co.uk a Chinese restaurant located in Sheffield, the UK.
  3. https://www.inksay.com the website you are browsing now.

With the HTTPS implemented on the website, all data of this site transmitted over the internet are encrypted. So the privacy of the site users is well protected, e.g. governmental surveillance, though there is no confidential information on this site, we guys with good conduct just do not like to be treated like that.

I choose the service offered by CloudFlare.com. It has free SSL certificates and with HSTS feature enabled. You do not have to pay anything and do any modification on your web hosting server. And of course, the powerful and free CDN by CloudFlare is also a killer selling point for me. All the pictures and CSS files of the site are now stored and served by the global CDN.

It is the encryption era of internet now. All up to date webmasters should take action to adopt HTTPS SSL for their websites. And it is cheap and pain-free.

An effective way to block spam comments of WordPress blog

As bloggers, we welcome comments on our posts, sharing different viewpoints and adding more content. However, a headache is SPAM comments, which are typically generated by spam bots.

WordPress officially offers a plugin Akismet that can reduces spam comments to a great extent. I still got hundreds of comments labelled as spam by Akismet plugin. I would be happier if there is a method to block spam comments even before them being left on the blog, which will reduce the loading work of web hosting server, and also keep the MYSQL database clean.

Finally, I found an effective way. Several weeks ago, I started to use Incapsula as my CDN provider to accelerate the speed of my blog worldwide. To my surprise, the using of Incapsula greatly avoided the number of spam comments, there were almost no items even in the spam comments category as it was when I use Akismet plugin.

I checked the trick behind Incapsula, finding the CDN provider offers a protective layer against spam comment bots. Almost all of the spam bots are blocked before they want to access the blog where to submit the spam comments.

Incapsula is a very good CND provider. It has a free plan for small websites. You can have it a try to speed up the performance of your website worldwide, meanwhile, say goodbye to spam comments.
