Since the very early days, the MySQL distribution packages contain a very useful commandline-tool named replace. As the name implies, it can be used to replace strings in text files. From the documentation:

The replace utility program changes strings in place in files or on the standard input. Invoke replace in one of the following ways:

shell> replace from to [from to] ... -- file [file] ...

This functionality comes in handy for performing consistent …

The potential for successfully building or extending a corporate identity based on Open Source depends on a company’s relationship towards an Open Source product. The graph below relates the extend of product ownership to the level of awareness potentially available for marketing:

Basically, the more you own the product, i.e. the more it is directly correlated to your company, the more you can make out of it.

If you’re the creator of the product (e.g. MySQL, the company, is the creator of MySQL, the database), you can utilize maximum awareness in your market. Your whole ecosystem will support your marketing efforts. For example, those providing extensions to your product, will automatically market your product while promoting their extension.

If you’re an external contributor to a product (e.g. providing patches with bug fixes), you …
