Patching software

June20

Here’s an interesting one.  I did not know that the term ‘patch’ as used to mean “apply an update to software” comes from the first computers.

In the days of punched paper tape, where binary commands were loaded into memory from tape, instead of recreating an entire punched paper tape to correct the software, a piece of sticky tape was applied to the paper tape to cover the hole in the paper and change the command, thus literally patching the software.

 

Moar info from wikipedia..

Technology and nostalgia

May17

I saw this the other day while looking at the TV series “Mad Men”.  Everybody deserves to do a presentation to clients once in their lives and smash it this hard.  A demonstration of the killer Don Draper pitch.  TV perfection.

From Mad Men, Series 1, episode 13.

There’s loads of great (open source) software out there but connecting it together to streamline it and thence make it really effective is the killer.

One of the problems with information technology is the rate at which the subject matter changes. This captures it nicely!

Ain't that the truth!
