MicroPython Repl command line is very nice, because you can telnet to the chip and read-and-evaluate python code. It is a great way of learning embedded IoT. The bad thing you cannot copy file while it is running, so experimenting get bad.

Exploring a 23 years old code base: LambdaMoo MUD Part 1

On these days my greek daemon (the one which talk to me about deep nerd programming) was interested on LambdaMoo.

LambdaMoo is an Object Oriented Multi User Dungeon born back in 1995. A MUD was a text based system you log in, talk with other, create adventures and so on. LambdaMoo has a script language and the entrire system could be customized.

The LambdaMoo last version 1.8.3 was a work in progress in 2008. LambdaMoo today is 23 years old.

So my daemon asked me: if you were able to do a tech refresh of LambdaMoo, waht will you eventually suggest?

To respond to this question, I need to study the original code

Initial attempt of flashback Database to restore from the last good restore point failed due to errors due to absence of flashback logs– this was a quicker option, but now ruled out.

Currently going ahead with full restoration in the Primary database – this activity is tentatively supposed to take 8-9 hours (in place of 6 hours earlier mentioned)

After some trial and error, I decided to switch to a new syntax highlighter library, mostly because the old one stopped working. I am very satisfied with Crayon because it is backward compatible with the previous plugin based on SyntaxHighlighter3 and offer also a nice in-line editor.
