Page Last Updated and Links Checked: 29 August 2003 Page Last Updated and Links Checked: 29 August 2003 Search Engines I Use
www.goeureka.com.au Goeureka. An Australian (and world) search engine which is gaining favour with me because of the simple way you can select search options.
Ask a question like "CSA?"
www.askjeeves.com Ask Jeeves World Wide.
www.ajkids.com Ask Jeeves for Kids.
www.goto.com
GoTo ..recommended by Mr Modem in in his book, Internet for Seniors. Uses a yahoo style
drill down search (which is good) but everyone linked has to pay (bad). Position is not based on amount paid and the payment is disclosed (good) but some of the links are poor (bad). There are no dead links (good). I'll stop now but you get the idea. It's the way maintained search engines will go.
One alternative used now, is to list everything (dead links and all) and charge "Partners" to be prominantly placed group at the top. The web's rapid expansion is causing problems for all players, good and bad.
www.overture.com
Overture, formerly known as GoTo, claims to be the world's leader in Pay-For-Performance search on the Internet. Actually filed suit against Google for patient infringement in May 2002. (The yellow is just me practicing a highlighter effect.)
www.teoma.com A seach engine that tries to overcome problems that have evolved with Google's page ranking system.
If you know a bit about something, put that knowledge to good use by contributing to a search engine with a difference!
Go to my DMOZ listing (in Grabbag of Links 3) where I praise, and provide a link to, the largest continually updated man made search engine in the world. If you find a dead or useless link ..delete it! If you know of something good that's not listed ..add it.
Wow ..that's what I call a good search engine!

Have Excel running and toggle between the tutorial and Excel by using Alt->Tab (use with the finder on a Mac). If you tile the windows you can switch back and forth by clicking on the window of the program you want to be active.
Good for beginners and particularly useful because it spells out how to tile (use two windows). Here you are working between a written tutorial and the application but it is a useful technique in general. Includes other tutorials on other topics.

User Tips And Resources
www.j-walk.com Spreadsheet guru, John Walkenbach's website.
j-walk.com/ss/excel His Excel home page (includes VBA). Use the left nav bar to go to the many excellent tips, faq's and links and information. Note: For 'developer' just think 'advanced user'. In any event visit all his sections so you appreciate what is covered in them.
My recent favourite tip: Format->Cells->Number->Custom then Type box enter 0, (that's a zero followed by a comma) thousands or 0.0, for thousands to (say) 1 decimal place, 0,, for millions or 0.00,, for millions to (say) two decimal places. Excellent for engineers wanting to display in kilo or mega but keep full number of digits eg 52145 (N) displayed only as 52.1 (kN). Appears (to me) undocumented. Use Format->Cells->Number->General to return to standard format.
Another found elsewhere is: Format->Cells->Custom (note no number this time) then Type box put in 0.0 then press Alt and input 248 from keypad then release the Alt. Gives one decimal place with degree symbol. If you had then typed C (after the Alt 248 via numberpad release Alt) you would have centigrade degrees. And they a still values.
And ROUND(A1,A2-1-INT(LOG10(ABS(A1)))) for value in A1 to the required number of signifigant figures in A2 (typically 3 in engineering). Not intuitive. Could say ROUND(A1,x-INT(LOG10(ABS(A1)))) where x is one less than the number of rquired signifigant figures (does not help a lot). Remember you are altering the value not just altering the visual display and have to use A1 itself for further calculations.
And =Now() and =TEXT(NOW(),"d mmmm, yyyy at h:mm AM/PM")
And concatinate: ="Report written on "&TEXT(NOW(),"d mmmm, yyyy at h:mm AM/PM")
www.cpearson.com Chip Pearson. An Excel expert's site (includes VBA).
www.cpearson.com/excel/array.htm Introduction to array formulas.
When an array formula is displayed, it is surrounded by braces {}. You do not enter the braces. Instead, when you enter an array formula, you press Ctrl+Shift+Enter, rather than just Enter. Excel will automatically add the braces. You must press Ctrl+Shift+Enter when you first enter an array formula and when you edit the formula later. Pressing Enter alone will return an incorrect result or a #VALUE! error.
(*Below is a snippet from Gnatt chart suggestion that is helping my approach to using the sign of x any components in a vector total to decide which quadrant the solution lies without going to VBA..)
We need to combine both of those conditions using the AND() function. This would be =AND(D$1>=$B2,D$1<=$C2)

Excel DataBase (List)
I have never needed or used Access. Here are some links that relate to the Excel Database facilty that I do use:-
(Note searches used were excel database tutorials and excel database functions.)
(Note also while everyone calls a database a database Excel uses the term "List" and "Data" a lot probably to try to differentiate from the Access offering which is a dedicated database package. Keep that in mind when using Help, book references or web searches.
excel/listhelp/listhelp1.html Use of list guidelines.

Note (from Excel200 Help): Excel includes 12 worksheet functions that analyze data stored in lists or databases.

The syntax is:-

www.janison.com.au
Janison Solutions. For Janison Toolbox, an Australian (Tamworth/Coff's Harbor) e-learning platform designed for TAFE/High School (taken up more by Universities so far). Wayne Houlden was in IT for 12 years and spent 7 years as a TAFE teacher. Started as a husband and wife business in a shed at the back of the house in 1998. In 1999, an American e-learning expert, Elliot Maise, reviewed Janison Toolbox in his TechLearn Trends e-newsletter (Houlden had sent him a press release!). The review prompted Microsoft to contact him and directed several online learning companies to him. They now turn over $1 million, have no debt, and employ 8 full-time staff.
The "Toolbox" name is related to it's component based nature. You can plug the Toolbox library components into your web pages like inserting an image.
There is a range of components including URL lists, annotations, glossaries, online assessments, files, media, flags, etc. Many components intelligently render for the browser used. If your browser supports dynamic html, the component will utilise dhtml for example. Behind the components is a learning environment management system and a central database built using the latest web development technologies (not cgi and perl scripts). Other tools provided include a dynamic template and publishing system which allows authors to publish new pages directly from their web browser efficiently.
You can create courses and content within your own discipline area, manage users and groups, as well as delivering your content from the site. You can use the Toolbox tools to quickly create dynamic and interactive content for your course, and use the management tools to review and assess the progress of students.
