Preventing Hidden Sheets from Appearing

When a sheet is hidden and the workbook is not protected, it will still appear in the list of hidden sheets in the Unhide box (from the Format menu, select Sheet, and then Unhide).

To prevent hidden sheets from appearing in the Unhide box:
1. Click the Properties icon OR from the Control Toolbox toolbar, click the Properties icon.
2. From the Visible dropdown list, select xlSheetVeryHidden.

To cancel the xlSheetVeryHidden option for a hidden sheet:
1. Press Alt+F11 to open the VBE.
2. Under VBAProject in the left pane, double-click the sheet name you want to unhide.
3. Press F4 or click the Properties icon to open the sheet's Properties dialog box.
4. In the Visible dropdown list, select xlSheetVisible.
5. Press Alt+F4 to close the VBE.

working with hidden rows

Here's a couple of macros that might be useful for working with hidden rows.

Why color hidden rows? If you are working with an unfamiliar file, it's very easy to unhide rows but then you have to remember which rows were hidden. This should help when the time comes.

Select a suitable column or add one if you like.

Sub ColorHiddenRows()
Dim rw As Range
For Each rw In Selection.Rows
If rw.Hidden = True Then
rw.Interior.ColorIndex = 34
End If
End Sub

Your hidden rows should now be easy to spot unless you are using Light Turquoise somewhere else in your sheet. (No problem, change the color or use something like rw.Value = "Hidden")

When it's time to hide them again, select the same column and run this.

Sub HideColoredRows()
Dim rw As Range
For Each rw In Selection.Rows
If rw.Interior.ColorIndex = 34 Then
rw.Hidden = True
End If
End Sub

When you are finished, don't forget to leave the sheet as you found it. (Making a copy before you start might be a good idea)

Backing Up MySQL

Backing up data and table definitions in MySQL is fairly simple. It does require some thought to minimize the amount of interference of service to the users of your databases. I recommend experiementing occasionally with the backup files to ensure that data is being backed up successfully and to ensure that you know how to restore the data quickly. You may also want to write up some documentation of how your particular system backups are made and how they are to be restored, which can be useful for colleagues when you're away from the office. It can also be useful for you — when there's a system failure, you can restore data more quickly and easily if you don't have to try to remember all the steps.

Intelligent Enterprise Magazine - Celko

In his article " Ten Things I Hate About You" Joe Celko has pointed out the logical flaws! I agree on most of the points though these are the most relevant to me!!
Lack of keys in tables. If you don't have a key, then you don't have a table. It is that fundamental and simple. If you have more than one key, then you are in trouble.

Insanely wide character columns. Why do you want to have everything in your table be VARCHAR(255)? This is the result of really bad design, where programmers pick the most general datatype they have.

Different names for the same data element. I have seen one person use the name "id" in the Requests table, then proceed to call the same data element "request_id" in the other tables. Why did it change in one table? What is fundamentally different about it, so that you must rename it?

Too many NULL-able columns. This is usually the sign of a denormalized table. Instead of thinking out the design to at least Third Normal form, the programmer just threw around a lot of NULLs.
