Muddiest Point #7
The Internet Archive was brought up briefly in class. I have seen the Internet Archive before, but do not know much about it. It seems like a great thing to me. But it sounds like they store a LOT of stuff. How do they manage to do this, especially in terms of money? I know they have supporters, but it seems like it would take a ton of resources to do what they do.
Reading Notes #8
W3schools HTML & CSS tutorials, HTML Cheatsheet
I have used HTML before, but not for years. The HTML Cheatsheet is a helpful quick reminder.
I've used the W3schools pages before. They are really good for either a quick introduction (that you can read more on when you are done if you want the big picture) or, as they are for me now, a refresher. They are perfect for that because they are more than a list of commands, but they do not take long at all, and they give you quick feedback. Good stuff.
Beyond HTML
This article reminds me of the idea behind CSS -- separation of format and content. There are other reasons for what the authors did, like security, but that separation seems to be the most important. This is interesting because the standards (like HTML) designed for the Internet were originally, with great forsight perhaps, intended to enforce that separation. Over time, it became more difficult to keep the format and content apart from each other, and recently great efforts have been made (and they have succeeded, I think) to regain the separation of format and content (like CSS).
I fount the article rather dry, but it is a good example of efforts made along these lines in the real world, so it is worth reading.

Muddiest Point #6
I understand IP addresses, at least the basics of how they work. I get the unique numbers and their division into 4 sets. But there is one thing I have wondered for a long time: Why is a local IP address almost always 192.168.1.whatever? Is there some significance to these numbers, or have they just been arbitrarily chosen as the standard/default local IP?
Reading Notes #7
How Internet Infrastructure Works
This is a nice brief overview of how all the connections are made to create the Internet. I suppose I already knew some of this, but it is not something you think about often, because it is so well hidden (most of the time) when you are connected to the Internet. This article reminded me of just how complicated the system is. Whether you love the Internet or think it is the worst thing ever created, it is hard to deny that it is an amazing achievement of mankind.
Dismantling Integrated Library Systems
I am not sure if I got much out of this article. It explains how getting newer systems to work with older ones is complicated. It then goes on to discuss what people have tried, and how complicated that has been. System developers have to work together. We have to rebuild the system. I do not mean that this is a bad article. But I am not sure it is for someone like me. Someone more directly involved with these systems (which perhaps I will be someday) would probably get more out of it.
Inside the Google Machine
This video was pretty interesting. It sort gave a glimpse of what goes on behind the curtains at Google. None of it is surprising -- I have heard enough about Google's unique way of operating, and it is definitely no shock that their search engine is used all around the world -- but it is still fascinating to see examples of and hear stories about things that go on because of Google.
