Your web browser probably warned you not too visit this page because... I let this site's SSL certificate expire. This site was developed through a sequence of homework assignments in early 2010. Actually getting and installing a real SSL certificate from an authority was for brownie points. But there's no sensitive data here, so I should remove support for secure browsing which just sets off alarms since the cert is expired. Some browsers may not let you visit a page with an expired SSL certificate. Happy Birthday to Heinrich Hertz. He would have been 155 years old today. I'm trying to get this posted while it's still Feb 22 in at least one time zone: Born Heinrich Rudolf Hertz on February 22, 1857 in Hamburg, Hertz proved the existence of electromagnetic radiation with experiments he performed at the University of Karlsruhe in 1887. Hertz thus verified the theoritical predictions of such radiation made by the great James Clerk Maxwell in 1865. Amazingly Hertz told his students that his discovery was absolutely useless. If he had not died much too young at the age of 36, he would have seen how valuable his work really was. Hertz is one of many great scientists never to win a Nobel prize - kinda like Sir Charles never getting an NBA ring - NOT! But who cares about Nobel prizes anymore anyway with nefarious recipients like Arafat and Obama :) Thanks Doug. I didn't have a clue what Google's wavy thing meant today. test post does this thing still work? double quotes Depending on the typeface, opening and closing quotation marks may be identical in form (called ?vertical?, ?straight?, or ?typewriter? quotation marks), or they may be distinctly left-handed and right-handed (?typographic? or, colloquially, ?curly? quotation marks). The closing single quotation mark is identical or similar in form to the apostrophe, and similar to the prime symbol. These three characters have quite different purposes, however. See also ditto mark. Reload bug There seems to be a reload bug that causes a topic to be reposted. I am testing for that. Enterprise Java Beans to be added, mobile friendly This semester I will add new features like emailing new topics and comments to subscribed users. I also want to make my blog mobile friendly to Android and iPhone users. I will rework my blog to use Enterprise Java Beans along the way. Official SSL certificate purchased An official SSL certificate has been purchased from Go Daddy. It was not too much of chore to install the certificate. A few keytool commands were necessary to generate the certificate request and import the Go Daddy bundle and keystore for vtrandalsblog.com. The hard part was getting the web server to use and display the common name (vtrandalsblog.com) instead of the IP address.
Filters have been added A Tracking Filter has been added. The plan is to track users as they click on advertisements. Also a Compression Filter using GZIP has been added to hopefully speed things up on my little Windows 2000 server. SQLNestedException issues resolved This turned out to be a lack of cleanup in my MySQL class usage. Many higher level methods that use my MySQL class return if an error occurs but did not call the cleanup method first. Anyway I am totally revising my MySQL to be like a singleton with regards to getting a MySQL Connection and Statement. My MySQL class will get a Connection and a Statement and store it in static (class) variables. So only one Connection and Statement are obtained and used for database transactions. I see no problem with this except perhaps a timeout may occur and the Connection and Statement will have to be reobtained somehow. I will have to look into timeouts associated with Connections and Statements. Advertising Now would be a good time to add some advertising since we are adding filters to our web apps. With a Tracking Filter we can log whenever someone clicks on an ad. Add Comment You have to have an account to make a comment on a topic. Read Comments Main Success Scenario:
A User (logged in or not) wants to read the comments on a post made by the Admin. The User checks the comment count to see if it is non-zero. If the comment count is non-zero the User clicks on comment below the Admin's post. This causes the Comment window to open showing the User the comments that have already been made. The User can now see and read the comments. When finished reading the comments the User closes the comment window.
Alternate Scenarios:
While the Comment window is still open, a logged in User decides to Add Comment (See Add Comment Use Case) Post Topic The Admin is logged in and wants to make a post to the Blog. As a result of being logged in as Admin some Admin options will appear on the blog screen. One of the options will be Add. The Admin clicks on Add. A window opens up with a text box for a title, a text box for a the contents of the post, and an option to publish the post. The Admin types a title into the title box. Below the title box the Admin types the contents of the post into post text box. When finished entering the title and the contents of the post the Admin clicks on publish to publish the post. The posts are persisted to the database with time and date and displayed on the Blog page in reverse chronological order. Problem Statement: The blog site main page will have a header of sorts - possibly just a picture and a title of the blog. Then below the header, posts can be entered by the blog owner/admin (me). Below each post will at least be options for the blog readers to see the number of comments and make comments. I do not want display the comments unless the reader clicks the comment option. The reader can then read the comments and will have the option to make a comment of their own. Admin posts and reader comments will be persisted in a database. I will require users to create an account to login before they can make a comment on a post. The Admin will review and approve comments before they are added to the comment section of a post. The Admin will have the ability to delete comments and edit or delete posts. I might add a search feature so readers can search for a post they might want to read and comment on. |
