Building Perl modules by hand

Two Perl posts in a row, but I was catching up on my Perl Advent calendar and realized I had never built a module by hand before, always relying on cpan or cpanm. It's not too hard and might save you one day.

Function signatures in Perl

I'm finally getting a chance to play with them and they seem great. Not the old prototypes, but brand new spiffy ones!

  sub some_function($a, $b) { 
  return $a + $b;
}
  

I think promises and futures are next on my Perl updating adventure

Regulations around government debt lead to crisis

Put briefly

By much favoring banks holding “safe” government debt and residential mortgages (demand-carbs) than loans to “risky” small businesses and entrepreneurs (supply-proteins), way too much debt has been generated against a weakly obese not muscular economy. Of course, in the process, bureaucracy autocracies were empowered, and houses transformed from home into valuable investment assets.

IBM I cloud instances available

Neato!

With ezDev, developers will get access to the latest Power9 and Power10 systems, equipped with the latest IBM i 7.4 and IBM i 7.5 operating systems and development tools. These ezDev cloud partitions include modern IBM compilers as well as open source technologies that are increasingly used in IBM i shops. This will allow developers to access the latest development tools and have full systems control with QSECOFR authority. (It is important to be able to test applications for security vulnerabilities as they are being coded or refactored, and ezDev allows this to be done on a true developer system, not on a production environment and includes their custom ezSecurity SIP package to configure and manage system security.)
