Keeping your Website Hack Free

May 8, 2015

I decided recently to dig into the Killersites website (on the directory level,) to see what I could clean up. It is one of the oldest web teaching sites in the world, it’s been online for over 19yrs now, and so it has had many changes over that time.

After 19yrs, you find yourself with a website directory structure that is deep and riddled with many nooks and crannies. So I went on the hunt and found some bugs down deep inside.

… 4-5 hrs later, I was able to clean house. I think! In the process, I gave Killersites a much needed spring-cleaning, if you will. I got rid of a bunch of pages and sections that might have some historical/sentimental value to me, but was filled with dated and irrelevant information. Besides, these are spots that hackers can leave their smelly eggs behind!

Some words of advice:

  1. Keep your sites clean in terms of the directory structure.
  2. Use a consistent naming convention for files and directories. This will make easier for you to spot malicious planted code.
  3. Delete your cgi-bin if you are not using it. Malicious code can be dropped into those.
  4. Don’t use PHP pages unless your site absolutely needs it. Each new PHP page is a potential attack point.
  5. Once your site is up and running where you want it to be, create a clean copy of it on your computer and zip it. This backup might come in handy if you need to wipe out an infected site. Of course, backups after each change is a must do.

Making your Website Mobile Friendly and Google Happy

April 21, 2015


I was recently asked this question from a student:

What do you think of Google’s new rating system to favor search results towards sites which are mobile-friendlier than other sites? Will there be a course to address this type of mobile-centric design in the future?

Yes, we have courses, both on and on the Mobile friendly sites are called ‘responsive’ … because their pages respond and resize based on the device being used to view them.

Our Webmentor courses:

introduction to Twitter Bootstrap
Responsive web design

And on the killervideostore:

Responsive web design DVD

And I plan on more later this year.

I think Google’s move makes sense when you think about it. Google always wants to cater to a broader audience, and web surfing is more of a mobile thing today, than it is a desktop or laptop thing.

We ourselves are slowing making our sites responsive, so far the following have been converted:

Why you should be teaching kids PHP, and not Python or Ruby

February 15, 2015

These days, Python and Ruby are popular programming languages with the tech startup crowd, and so, many of the venture capital backed ‘teach code’ startups have ruby or python courses targeted at kids. The problem is, that these are not the best languages to teach programming with – especially in K12.

Why is PHP better?
