Transcript

Normally, when I film these videos, I’m at the Centre for Computing History in Cambridge. Unfortunately, it is April 2020 as I record this, and times being as they are, I have to make do with a green-screen. But why simulate that same location? I could be anywhere with this, right? Well, first, this would have been a great subject to film at the co... Read More

Questions & Answers

Q: Why can't you name a file "Con" in Windows 10?

In Windows 10, you cannot name a file "Con" because it is a reserved name used for device files in MS-DOS. The system still maintains this restriction to ensure compatibility with old printers and devices.

Q: What is the purpose of device files in MS-DOS?

Device files in MS-DOS served as an interface between programs and external devices like printers. Programs could save data to device files, and the device driver would handle the communication and functionality with the specific device.

Q: How does backwards compatibility affect video games?

Backwards compatibility in video games allows older games to be played on newer consoles, but it has limitations. Emulation is often required to translate commands between systems, and some bugs may be carried over from the older games.

Q: Why does Microsoft Excel still consider the 29th of February, 1900 a leap year?

Microsoft Excel copied a bug from Lotus 1-2-3, a competing program, that incorrectly identified 1900 as a leap year. This bug remains in Excel for backwards compatibility reasons, as changing it could break existing spreadsheets.
