  1. I like to thank you for a amazing site. I love the content, examples, exercises, and opportunity to get certified in each language / technology. That said, I really like to know more about cookies, how they differ from trackers and other information collection methods so I can try to be more selective about what information I share with with various sites I visit. I did see the Cookies section under Java Script, and I wonder if it is possible for someone to provide a bit more detail in this area. Ideally I like to be able to view and control what information I share with sites. I have reviewed
  2. Greetings You are asking a strategy question, and it is good that you are interested in it. I do like the suggestions made also. Reading from a variety of sources helps. The most important activity in learning programming, it actually coding. I have revised my previous post, after reading the comment about links. Sorry I did not know about it. Regards- Samuel
  3. Thank you so much. This was exactly what I was missing. I had to refresh my memory on binary representation, but I am good now. Just in case someone else may want to know the details this link was very helpful for me.
  4. There is an example under JavaScript bitwise title which says here is how to convert a decimal to binary: document.getElementById("demo").innerHTML = dec2bin(-5); function dec2bin(dec){ return (dec >>> 0).toString(2); } I do not quite follow what is happening inside the function, and when does -5 convert to binary. What happens to -5 as a decimal once it is passed to the function? I mean, I can just try to remember it, but given the context of the topic and the operators discussed earlier in this section, I do not see what is happening. I also found a thread on SO about it he
  5. Ok. It may have to do with the security settings of my browser. I think I disabled JavaScript before, and just checked it again and it was enabled. I also clear my browser cookies and whatnot often. I appreciate your response.
  6. Thank you for the response. Here is one.
  7. Greetings Thank you so much for creating this great content. I have learned so much by reading the html and CSS tutorials. I am towards the end of the CSS tutorials section, and have read all the html tutorials content. I used to be able to cut and past the tryit source into a text file and try it locally, but I can no longer do that. How can I fix this please? I believe the last time I did this successfully I was viewing html tutorials, but I am now at the end of the CSS section and can not do it. Sam
