A Curious Programmer

Some interesting discussion on roles vs inheritance on SillyMoose’s blog (h/t to Planet Moose)

The executive summary:

• Roles are semantically safer than multiple inheritance because methods from the roles are loaded into the class at compile time and any name clashes are picked up then.
• Roles cannot be instantiated.

Capturing a couple of old links so I don’t lose them:

• Stevan Little writes about porting Bread::Board to p5-mopp5-mop
• A follow-up from Zak on porting Hashids

An aside… in my industry, we’re probably not going to be seeing any of this until 2020 or so. We’re still stuck on 5.10 (RHEL6).

I’m looking for advice on developing a standalone web app for Windows. That is, the server side would be running locally.

So far I’ve got notes on Perl and necessary modules.

• Strawberry Perl
• DBI and DBD::SQLite
• Plack and Mojolicious or Dancer
• AnyEvent and Twiggy ?

I’m planning to remove MinGW / and the compiler to make the final package smaller.

Here is the list of installation software.

At the moment I’m leaning towards NSIS for no particular reason.

What I’m thinking is that the installation script will check for the existence of C:\Strawberry. Then it will run the Perl it finds there.

• If it can’t find the directory, it can install it.
• If the directory exists and the Perl is good, use it.
• If the directory exists and the Perl is not good, abort with an error message.

Any input welcome.
