If you want PCRE on the command line but your  grep(1)  does  not
offer  `-P'  (*not* offering it is what it *should* do!), you can
use this one:

     perlgrep() {
             perl -e 'my $re = shift; print grep { /$re/ } <>;' "$@"
     }

Discovered  some interesting facts about the GIF format.  [1] You
*are* able to use more than 256 colors, just not within one block
...  but  you can use multiple blocks for building True Color GIF
images!

Here is what helped me mostly while working with old existing code.

Analyzing: Here are some things that helped my analyzing software problems in our codebase.

Fixing: Here are some tricks for fixing existing code more easily.

Preventing: Here are some hints how you can prevent some bugs.

03.01.2023

What did I learn as IT specialist for system integration?

– You only learn as much as you want to learn.

– No panic!

– Unix & command line <3

– Read the official documentation.

– Always make a backup (never use “sudo” drunken).

– Be honest with customers, employees and yourself.

– Ask questions if you don’t understand something.

– Think about what you are doing (not only at work).

– Use Google correctly …

What did I learn as IT specialist for application development?

– You never stop learning…

– Try to write code every day. (but set yourself a LIMIT)

– Think in modules and packages…

– Open-Source-Software

– Git & Good

– Use GitHub and learn from the best.

– try { tests() }

– Automate your tests.

– Deployment is also important.

– Understanding concepts is more important than implementing them.

– Solving problems also means understanding customers.

– Solving problems also means understanding processes.

– Spread code across multiple files.

– Readability comes first!

– Good naming is one of the most difficult tasks in programming.

– Save on comments (at least inline)…

– Consistency in a project is more important than personal preferences!

– A uniform code style has a positive effect on quality!

– Use functional principles & object-oriented concepts.

– Please do not use global variables!

– Learn to use your tools properly!

– Performance?

– Exceptions === Exceptions

– Finish your work

– Source code should be searchable [Ctrl + F] …

– Program for your use case!

– KISS – Keep it simple, stupid.

– DRY – Don’t Reap Yourself.

– The will to learn and understand something new is more important than previous knowledge.

– Read good books and magazines.

– Follow other programmers on Twitter / GitHub / dev.to / YouTube / Medium / …

– Listen to podcasts & subscribe to RSS feeds / newsletters & watch videos, for example from web conferences

– Attend Meetup’s & web conferences and talk to other developers.
