When to go interactive

  So I want to discuss  when you might think about ticking things  and going interactive.  And listen, the spoiler alert on this one is,  my answer is kind of, always, sort of.  If you can,  if you have the time and the budget  to make interactive things, you should.  So that's the short answer, but here's the longer answer.  I like to start off this way.  How did you learn to count?  When I was a little kid, I learned using these,  they're called Montessori counting beads.  And so when I was three years old,  someone handed me three of those little beads  in the upper-left-hand corner and said, that's three.  And that's not that weird.  Everybody learns to count that way probably with blocks  or something like that.  But then they handed me this single-wired together object  in the far-upper-right and said, that's 10.  Then they handed me the flat object in front of those ...

Keys and unique values

 When information is stored in a database, we'll usually want to read or access that data, or part of it, for some particular purpose. Let's say we want to look up a customer's phone number so we can call them about their upcoming reservation. In a table of a few hundred customers, we might have customer names and their phone numbers, and it's pretty simple to ask the database for a customer's information. We could say, give me the record for Taylor Jenkins, and the database would return their row. But what happens when two people have the same name? That's a fairly common problem when dealing with names. If we were to ask the database to give us records matching a name that's shared by a few customers, we'd get back all the records that match.  So how do we know which is the correct customer? We certainly wouldn't want to call the wrong person. Unique values allow us to unlock the power that databases provide. In a database, a unique value is a valu...

Selecting transcript lines in this section will navigate to timestamp in the vide Data conversion is the conversion of computer data from one format to another. Throughout a computer environment, data is encoded in a variety of ways. For example, computer hardware is built on the basis of certain standards, which requires that data contains, for example, parity bit checks. Similarly, the operating system is predicated on certain standards for data and file handling. Furthermore, each computer program handles data in a different manner. Whenever any one of these variables is changed, data must be converted in some way before it can be used by a different computer, operating system or program.  Even different versions of these elements usually involve different data structures. For example, the changing of bits from one format to another, usually for the purpose of application interoperability or of capability of using new features, is merely a data conversion. Data conversions may b...
