Rather, back-testing can really only show you what DIDN’T work well in the past, so you can avoid repeating those mistakes, or at least be aware of those risks. Back-testing can never prove something will work best going forward. Also, back-testing will never show you extraordinary events, such as civil unrest, unprecedented government intervention in the markets, inflation, etc. These risks need to have some diversification applied as well and the Forever Portfolio actually considers these risks that spreadsheet-only portfolios do not.
Have you forgotten your Excel spreadsheet password? If so, here’s how you may retrieve your data. There is software that you can find on the internet that can help you access your documents. The basic software is free and on most occasions the only program required for users. To remove the password that was set on the excel file you can use the password remover software. This is is a program that may be used to remove, retrei or unlock a password on an Excel sheet or workbook.
There are other ways to import data into your database, including using Web forms or setting up a special email inbox that will post the information automatically. These tasks will take some skill and some HTML knowledge, however. Other tools require more programming skill to do what Trackvia does with a few mouse clicks, or are more cumbersome to manipulate, or don’t have the automatic defaults that make setup as easy as Trackvia. Did I mention the cost? $10 per month per user. This includes an unlimited number of databases and up to a GB of attachment storage (meaning that you aren’t charged for the actual records themselves that are stored). If you sign up before October 1 for an account, the company will give you several additional features free.
In the past, the easiest way to share a small database was to create a spreadsheet and email it to your collaborators. This time-tested method has withstood more sophisticated competition for several reasons: First, databases are still tricky for some people to understand. While relational databases can be thought of as tables that have several indexes, this is more than many people want to deal with. Second, the collaboration tools are tough to learn and use. Look at how many people still use Lotus Notes for email and not much else. And since most of us are comfortable with email, using it as the transportation system isn’t all that taxing. Until the day comes when three people are working on the same spreadsheet and make conflicting changes.
There are two information-related walls that a young company hits while trying to grow. The first wall is what I call ”spreadsheet suffocation.” It is that stage of information sharing pain that causes people to start cussing. Where did you save the Johnson calculations? Who has the orders spreadsheet locked? Where did my new inventory list go? Did someone write over it? There was 2 days work in that spreadsheet!
Finally, when you add the Web and Internet-based access to the data, you have greatly increased the skill level required to create and manage your database. While there are some really good Internet-facing database programs (Alpha Software, Filemaker, Quickbase from Intuit, and DabbleDb - just to name a few that I know of), none of these are as easy to setup and manipulate as Trackvia.com, a service that has been out for the past year but recently gotten some much-needed improvements.
Most passwords that are used to protect files are usually given to the workbook or individual spreadsheets. This allows users to view the file without making any changes to the structure. The only person who can modify the data is the creator of the file. Download the software and when complete it will automatically open Excel and ask you if you will like to enable macros that are part of the add-ins. You should click enable and then open the spreadsheet that you want to unlock. Two new options will appear under the Tools button; Unprotect Workbook and Unprotect Sheet. This program only works on 2000 and 2003 versions of Windows. Windows 2007 uses a more complex encryption method making it too difficult to crack.
