4. - Not going to talk a lot about
these
- Briefly talk about Sawyer's
talk on Perl 5: The Past, The
Present and One Possible
Future
Keynotes

5. - This is an abbreviated Sawyer's
list of what he'd like to see
- I myself (and Sawyer too from
his comments), don't use an IDE,
but the kids these
days, it's what they start with.
Perl5: The Past, The Present, and One Possible
Future
by Sawyer X
— Reduced ambiguity
— Best practice as defaults
— One clear way to do most things
— Parallelism, OO, etc.
— Comfortable debugger
— Better IDE support

6. Sessions

7. - Please feel free to help me fill
in things
- ask questions
Disclaimer
I always intend to take notes as the
presentation are happening. This rarely
happens as I get more drawn into the
presentation. It's either pay attention or
take notes, and I'd rather pay attention.

8. - The software vendor didn't help
- The client didn't have any idea
- none of the usual database
indicators
- ended up comparing directory
structures after making 1 small
change
Building a Bridge to a Legacy Application -
How Hard Can that Be?
by M. Scott Ford
Specializes in digging through legacy code and
trying to figure out how it works. In this
talk he describes a recent project in which
they were unable to determine the data store.

9. - The Boy Scouts are going through major
changes

leadership courses to demonstrate the
similarities, and how the Boy Scouts are
handling the challenges.

10. - While I use tmux daily and
am fairly fluent with it
- if I learn one thing from this
talk the return on investment is
huge
Organized Development with tmux
by Doug Bell (preaction)
Doug takes a tour of starting with a fresh
tmux installation and walks common and useful
settings.
https:&'youtu.be/o7Dg1kmjhfQ 10

11. - within the first 10 minutes, Doug
discusses the use of last-window
- I've been hunting and next/prev between
sessions like a heathen
- I immediately started updating my
tmux.conf
- I had the default for last-window
bound to another key and hadn't rebound it.
Organized Development with tmux
Allow navigation between the two most recently
active windows
bind s last-window

12. - Unfortunately its syntax can
be somewhat cryptic
- Having the availability of
someone to help understand.
Non-trivial jq
by David Hand
jq is a very useful tool for command line work
with JSON.
David provides examples of extracting and
changing JSON values with jq

13. - the title of this talk is referencing the
Space Cadet keyboard
- genehack is a keyboard nerd too.
- including some that I would call fairly
non-standard
- blues, got to be blues
- they do tend to annoy the family
though
Confessions of a Space Cadet
by John Anderson (genehack)
This talk was an introduction into the world of
mechanical keyboards and could be the first
step down the rabbit hole for a number of
people.
genehack describes the different layouts of
keyboards and explains the different Cherry MX
switches.

18. - Abigail's talks are always very
informative, and any new
nuggets of information on
writing regular expressions is
always welcome.
- Abigail's talks are not recorded.
Regexp Mini Tutorial: Assertions
by Abigail
Abigail demonstrates different regular
expression matches and replacements.
TPCiP 2019 Wrap up /0 Shawn Sorichetti /0 @ssoriche 18

19. - a bit of a contrived example, but
couldn't think of a better one
- The K directive tells the regular
expression engine to forget what it
just matched and continue from the
current position to try and match the
rest of the pattern
Regexp Mini Tutorial: Assertions
Using the K directive:
my $text = 'this is one two two many';
$text =~ s/ (two) s+ two s+ /$1 too /gx
becomes:
my $text = 'this is one two two many';
$text =~ s/ two s+ K two s+ /too /g

20. - Unfortunately video of this talk has not
been posted. I've contacted Chris to see
if he knows why, but he hasn't been
informed as to why either.
- This talk is designed to lead to
discussion in the audience.
- Chris has given this talk previously and
the video is available here.
I Never Metaphor I Didn't Like: How Cognitive
Linguistics Can Help You Be A (More) Bad-ass
Developer
by Chris Prather (perigrin)
Chris walks through what metaphors are and the
constructs that comprise them.
We use metaphors every day in the computing
environment. From user interface design to
communicating code details between teams of
developers.
TPCiP 2019 Wrap up /0 Shawn Sorichetti /0 @ssoriche 20

21. - Unfortunately some last minute CSS
changes led to a presentation that's
syntax highlighting left the slides
unreadable at a distance.
- I'm a firm believer that learning a
different language strengthens the
understanding of those I already know.
Readin' Rust
by Andrew Grangaard (Mr Spaz)
A tour of the Rust programming language. A
compiled typed language for "systems
programming".
This is one of the talks that reviewing the
slides later would be informative.

22. - Ingy has been working on creating tab completion
for programs that don't have it
- The project includes a number of repositories for
different commands, but there is still a lot of work to
do.
- At PTS 2019 he was demonstrating completion for
cpanm which included full distribution name
completion on the command line.
- Really impressive, so I was looking forward to how
far along the project is.
CompleteShell - Tab Completion for Every Shell
by Ingy döt Net
The goal of the project is provide a simple
mechanism for developers to add the completion
files and man pages for their command line
tools. A DSL has been defined that when used
with the tool generates the files required to
add completion.

23. - I consider myself an intermediate git user.
- I can get myself out of trouble,
- I've created and used many a release
process,
- and I know that I don't know everything.
- This was a shortened talk
- Find any talks by genehack on git, they're
all useful
C'mon Git Happy
by John Anderson (genehack)
This talk focuses on maintaining the git
graph. The relationships that are created
during the git workflow.
genehack takes a tour of aliases,
configuration settings, and commands that help
keep it clean.
https:&'youtu.be/oEKXV-_o3YQ 23

24. - with so many talks it's hard to
see everything
The One I didn't See

25. - I did not attend this talk
- immediately after everyone was
talking about the fantastic job that
@yomilly did
- As soon as I returned home this
talk went on the main TV and I
watched it with my family.
Perl Out Loud
Emily suffers from RSI and has tried all
different methods to allow her to continue to
work.
She's settled on programming using her voice.
This talk demonstrates her set up.
https:&'youtu.be/Mz3JeYfBTcY 25

26. - There's no need for
abbreviations. Abbreviations
hinder accessibility, as well
they can affect clarity.
Perl Out Loud
What I took from the talk:
1. Emily is a great speaker
2. Speech to text technology has come a long
way
3. Be considerate to the names given to methods
and variables.
https:&'youtu.be/Mz3JeYfBTcY 26

27. - there are many lightning
talks, not going to cover them
all
Lightning Talks
There are a lot of different lightning talks
on various topics, some related to
perl, some related to other aspects of
programming, and some with nothing at all
to do with either.
TPCiP 2019 Wrap up /0 Shawn Sorichetti /0 @ssoriche 27

28. To undef or not to undef
by Cees Hek
Cees revised his talk from Toronto Perl Mongers and presented it as a shorter
lightning talk. This talk gets right to the point of the differences between
$var = undef;
and
undef($var);
Why you might want to use one over the other, but mostly shouldn't care.
https:&'youtu.be/XvNTvqUYIAs 28

29. - Under the category of nothing to
do with programming but really
interesting
- I am not one that likes my
penmanship
- Might pick up one of the cheaper
models he mentions to try it out.
Fountain Pens
by Mike Fragassi
This lightning talk on fountain pens is really
well done. He discusses different types of
pens at different price points.
https:&'youtu.be/1px2VHqOLM4 29

30. - I'll admit, when Ingy stood up on
stage and stated that this was the
topic of his talk, I was prepared to
hear a lot of backlash from the
audience.
- Surprisingly there was none at all.
A New Name for Perl
Ingy proposes that:
— Perl be the name of the community
— Perl be the name of the language family
— perl 5 be the implementation of
— perl 6 be the implementation of the language.
Watch the talk. It's interesting.

31. Interesting things

32. - Yes that is coleslaw on the
sandwich
- and yes, those are fries on
there too
