Computer science is a problem solving

It is possible to compare computational thinking with problem solving. You can think of a sudoku game as an example of a problem to solve.

Computational thinking find a way to solve one problem and apply the same principle to solve other similar problems. It will be a bad idea to spend days just to solve a single problem and then create a solution for another one, another one and so on.

Some problems will require a different solution, however if these are similar to each other, then why to create a computational solution for each one of them separately. Having one solution for them all will be more efficient and more comprehensive.

Of course these problems need to be related to each other. If they are not related, then computational solutions will be very complex, and maybe it is a good idea to create multiple computational solutions that will handle things from each area separately.

Please think of word processors and databases.

Database engines are not meant to do word processing, so the word processors are not meant to be databases.

Absolute and relative path in HTML pages

HTML documents can have relative or absolute links to other web pages. Relative links keeps a visitor on the same web site. Relative links are pointers to other web pages on the same web site. They just contain this page filename. Absolute links on other hand contain full path including protocol and domain name to access the page. Absolute links can point to the same web site or they can point to a different web site.

Errors

It is a good idea to send errors in production environment to error log. Errors may contain sensitive information. Even so errors maybe helpful to development team or to QA team, errors need to be suppressed in production environment for viewing by everyone. Errors are good way to troubleshoot an issue therefore only trusted people can have access to this information. If not a trusted person get an access to this information, this information maybe used against the company and for a personal benefit. What to do in a case when there are more servers than one? Even so it is possible to inspect the log files in a single server, however it is impossible to do so when there is more than one server is available and web traffic is redirected to a different server each time. Log aggregation is needed in this case. All of the logs will be send to a central location. Logs may contain sensitive information. Please consult your company lawyer of how long logs can be stored, because logs can be use...

goto PHP operator

goto operator will skip execution of code and continue execution of a code that follows a label to which goto operator points to. If code has many goto operators, than this code probably needs a revision. It is possible to write code that executes without goto operators.
