Here is a small photo album from our trip. Cancun 2005

I think this can be answered from the user’s perspective and from the developer’s perspective. I think a page can be considered well designed if it looks good, works with many browsers, and can be maintained by others than the original author. From the user’s perspective, I was able to come up with the following list: Accessibility - the page is compatible with screen readers and alternate input devices. At work we recently went through a remediation process with one of our web sites. We needed to assure HR the site was compatible with accessibility utilities. I think about 75% of this can be handled by writing good HTML source. In addition to this, testing tools such as WebKing can help identify other problems that can prevent the web code from working in certain situations. Navigation - the page is easy to leave. Another way to say it is the page should have the necessary links to navigate away to other major areas, if it is part of a larger web site. Placement - the page is easy to find in the site and navigate to. Compatibility - the page can be loaded and properly displayed in popular browsers. I think in e-commerce, it is important to give this item some amount of priority. You want to encourage visitors to browse and buy regardless of the specific brand or version of their technical resources. This is also important to consider if your viewer base consists of users with handhelds or Internet-capable cell phones. Organization - information on the page is presented in a visually appealing way, including text style choice and page positioning. From the developer’s perspective: Documentation - comments in the code or a short design note helps the author remember what they did and helps other maintain the page later. Organization - the page’s source is consistently organized and formatted into blocks. I think with today’s tools that can reformat source code, this is less of a problem.

The difference that draws my attention is that print media is static - ink or other compound is bonded to a page and is permanently fixed. Unlike a web site, there is no hope of that print jumping up and rearranging itself if the user wants to see a different layout. The first difference is that web publishing has the possibility of introducing dynamic content to the user in a number of different ways. Web sites used for e-commerce have the ability to show customized content based on the user’s past purchase history, or if they have a particular preference for how the page is arranged. My Yahoo is another example, where each user can have a customized view of information they choose. The other primary difference I can think of between web and print media is that designing for a newspaper, for example, is a controlled process from end to end, unlike a web page in which the rendering and quality of the final product is out of the control of the publisher of the content. The newspaper publisher chooses layout, fonts and other aspects of style just list a web published would, but the similarity stops there. A print publisher also chooses the rendering mechanism and the paper it is printed on. In web publishing, that last step is somewhat variable in that browser differences have the possibility of producing different output with the same HTML code.

I had an idea today about how to make servers self destruct in case of some type of security breach. I guess this might be influenced by the Star Trek movie I saw the other night. They seem to blow up more Enterprises in the recent stories. My idea is to keep a blank CD-R in the drive of the server at all times. On hard disk there is an ISO file that is written to the CD-R on demand and then the server is rebooted. The server will ignore the blank CD-R during reboots until it is written with a valid image. The contents of the ISO needs to be a boot loader and kernel, like Grub and Linux plus a file system with a wipe program. The wipe program is started once the kernel is booted and it iterates through the collection of hard drives, which the kernel found during the boot process, and writes over them with a pattern.This kind of the self destruct sequence can be automated with a script and invoked through a terminal on the local network or through a VPN. It could also be loaded into cron and deactivated on a regular basis from going off.So, if your servers are under heavy attack, and you have no other choice, start the count down. :-)

I graduate in November and then I can grow up and get a job.I have been attending a UNIX course in school the past few weeks. This week we have been studying some cost configurations in running UNIX and Linux for various network serving roles. A topic that came up was the benefit of using the free Linux distributions and related software for low cost server operations. I have a home network, and I think I count as a low cost operation. I will not spend excessive money on my network, and I have never felt compelled to spend money because software I need could be obtained for free.For example, my primary server at home routes email, serves several web sites, and acts as a router between the public Internet and my home network. It is a big server. I run Fedora Core 3 as my operating system.The email routing incorporates dovecot, sendmail, amavisd-new, SpamAssassin, and ClamAV. The last three of these programs working in tandem keep dangerous email for passing through my server. The spam analyzer learns the difference betweeen wanted and unwanted email, while the open source ClamAV scanner automatically checks for updated virus signatures every hour. The amavisd program acts as the mediator between the spam and virus services and my email server. The best part is that tainted email is rejected in real time while the sender is trying to move it to my server.As a network router, my giant egg basket of a server watches both incoming and outgoing connections for suspicious activity on all network adapters using Snort.What would I pay to recreate this configuration with commercial software?
