The Mixed Case Tile
Question

A letter following an apostrophe is capitalized when the Mixed Case ◊ tile is used. Example: "Robert'S question." Are there times when characters following an apostrophe SHOULD be shown as upper case? If this is how it’s supposed to be, is there a workaround for the example above?

Answer

Helix determines where one word ends and another begins by consulting its Keyword Separator Table, a configurable table that determines which characters indicate the space between words. By default, the apostrophe is a keyword separator character, and so the Mixed Case tile capitalizes the character after an apostrophe. This issue can be avoided by editing the table to treat the apostrophe as a word character, but that may have undesirable effects in other places, such as changing “O’Malley” to “O’malley”.

The Abacus Expression
Question

A complex abacus becomes extremely difficult to read, what with arrows pointing here and there. Even a neatly arranged abacus feel non-intuitive to a programmer. Is there a better way to read an abacus?

Answer

Helix 6.2 introduced the Abacus Expression Language (AEL) — a text-based version of the abacus. The syntax used in AEL should be familiar to users who have experience with programming languages such as Perl, Python, AppleScript, etc.
