Webhosting For A Large Art Project?

denshao2 If it's only for your class (137 comments)

I would host it at home. If it's only for a professor to see, you should not be getting a lot of traffic. Just keep it on a machine that is separate from anything important.

Fee Increase Attempt Inspires 'Dump Your Bank Day'

denshao2 I'm probably not the only one (667 comments)

I had heard of credit unions before, but I didn't know what they were and I didn't have sufficient interest to find out. I only researched it after this Bank of America incident. Now that I know, it's obvious to me that a credit union is better.

I'm not sure about the ones that they are using, but very durable anti-reflective coatings have been available for years. They are used in UV filters for cameras.

I definitely agree with this. I have learned far more by creating my own projects than I have from taking classes, reading books, or reading other people's code.

denshao2 Energy Cost? (139 comments)

If the total energy/financial cost of causing rain is more than the cost of transporting water via conventional means, then it's not really practical.

Moon Younger Than Previously Thought

denshao2 Uniform composition? (212 comments)

It is my understanding that the surface is composed of meteorites that hit long after the core formed. Dating the surface should not give you the age of the moon as a whole unless it's uniform in composition. If you do the same to date the Earth, then creationists will have plenty more fuel to support their story.

Seeing Ads Again

denshao2 denshao2 writes  |  more than 4 years ago I have been developing a new social blogging site for the past three months. I am now at the point of focusing on advertising. I started with Google Ads, but that only earns an average of 30 to 40 cents per click and most people just ignore it.

After extensively researching alternatives, I enrolled in Commission Junction and Linksynergy. I have not yet determined the final form of how I will incorporate them into my site. For now, I have them in a sponsors page which I doubt anyone will even look at.

Constructing this page required unblocking many domains that I had previously blocked to prevent seeing ads. In becoming "one of them" I have also forced myself to see advertising. I could block them again after I finish development, but I prefer to be able to monitor my site to see that everything is working.

Appending Text To DIVs

denshao2 denshao2 writes  |  more than 4 years ago

This is actually about Javascript, but I see that Slashdot does not have a category for that.

I'm designing an AJAX chat system for my site and everything seemed fine until I decided to test embedding of a video. The problem is that the video resets every time a new line of text is added to the chat. I have been using the following method to insert new text into the DIV that holds the chat text:

MyDIV.innerHTML+=userinput

The += technique seems to cause a rewrite of the contents of the DIV instead of merely appending at the end. I have only tested in Firefox 3.0.9 and don't know if it works in other browsers, but it doesn't really matter. If it doesn't work in this browser, then I can't use it.

An alternative method for appending text is to create a text node and to append it. The problem with that is text nodes don't allow HTML. Everything in the text node is displayed as plain text with the HTML code visible. I can append elements to get the formatting that I want for the user name and time, but the situation gets complicated if I want to allow users to insert their own HTML within the chat. The only solution I see to make this technique work is to do some complicated lexical analysis which seems like too much work just to let people watch videos inside of chat.
