Keeping it small - Getting to know the Slim PHP micro frameworkJeremy Kendall
Learn what the big deal is about PHP micro frameworks by taking a tour through an application written in Slim PHP. I'll briefly introduce you to some high level concepts, show how those concepts can be implemented in Slim, and see how powerful and elegant micro framework can be.
Introduction for beginners how to start laravel5 application in easy way and what to be known before start working with laravel5. Prerequisite for this course is basic oops concepts, PHP 5.4 + knowledge , MVC pattern knowledge will be advantage.
Keep hearing about Plack and PSGI, and not really sure what they're for, and why they're popular? Maybe you're using Plack at work, and you're still copying-and-pasting `builder` lines in to your code without really knowing what's going on? What's the relationship between Plack, PSGI, and CGI? Plack from first principles works up from how CGI works, the evolution that PSGI represents, and how Plack provides a user-friendly layer on top of that.

Various coding styles I hate seeing. It's a rant, but a fun one. Uses Spiderman to help illustrate my angst.

This talk was originally given at Cluj.pm, on November 7th, 2013.
These are the slides for the talk I gave at YAPC::EU 2012 called Asynchronous Programming FTW! It tries to explain what async programming is with examples of a few Perl async frameworks.
This is the Moose talk I gave at YAPC::NA 2012.
It included a practical example of a Moose objects code, a simple app called Comican. The code is not available online. If you want it, just email me (sawyer ATT cpan DOTT org).
Our local state, my, my - Understanding Perl variablesxSawyer
This talk should explain the different ways to define Perl variables. What each one does and how they work. It will help you avoid problems with incorrect variable definition and to learn how to use variables in a smarter manner.
This was the last talk of a Tel Aviv Perl Mongers (TA.pm) group meeting.
Your first website in under a minute with DancerxSawyer
Learn how to write your first website using Perl and Dancer in under a minute!
This is a lightning talk given at a Tel Aviv Perl Mongers (TA.pm) group meeting.
These are the slides I used at a lecture in YAPC::EU 2010 about running Perl on the Android mobile device operating system.
There is a screencast (audio + video) of it, which will hopefully become available soon.
This an attempt I've made at installing Dancer, the Perl web framework, on an Android emulator using ASE (Android Scripting Environment).
Plenty of things have changed since then, and when I make another attempt, I'll publish that as well.
These are slides from a lecture on Red Flags in Programming that took place at an Israeli Open Source Developers meeting.
Red flags in programming are signs that you likely made a mistake with your application design or code.
Noticing and avoiding these mistakes help us write better code, at any language.
The subject related to mostly dynamic (higher level) languages, even though the sample code is in Perl.
"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

10. Nutcases?
● Yes, we are insane (but not LISP-insane)
● Insanity is a whole lot of fun!
● Insanity gives us flexibility
● Flexibility gives us cool stuff
● Like Moose and meta-programming
● Like DBIx::Class
● Like Dancer
15. CGI
● Most common web programming model
● Easy to configure on a web server
● Programmer gets everything in %ENV
● First paragraph in output is for the browser
● Second paragraph is content for the browser
● Error prone, depressing, boring, long
16. MVC
● Separation of Model, View, Controller
● Much more flexible and scalable
● Uses “Namespace Matching”
● Sometimes an over-kill
● MVC framework example: Catalyst
18. Dancer treats
● Both read and write, easily!
● Route-based (started as a port of Sinatra)
● PSGI/Plack compliant
● Minimal dependencies
● Any app is also a web server
● CPAN-friendly (<3 CPAN)
19. Recipe for Dancing
● Take an HTTP method
● Add a path to that
● Mix with a subroutine
● And sprinkle plugins and keywords on top
21. Dancer
● Paths can contain variables
get '/hello/:entity/'
● Support optional variables
get '/hello/:entity?'
● Paths can be Regular Expressions
get qr{/ (w+) / d{2,3} (.+)? }x
24. More nifty stuff
● headers 'MyXHeader' => 'Value'
● send_file('report.tar.gz')
● set_cookie name => 'value',
expires => ( time + 3600 ),
domain => 'foo.com'
● status 'not_found'
● to_json, to_yaml, to_xml
● my $file = upload('file_input')
● my $all_uploads = request>uploads
25. Dancer as Perl philosophy
● Dancer is succinct, efficient and easy to work with
● Dancer is daring
(Probably the only web framework with route caching)
(Websockets in the works!)
● Dancer has a lot of plugins:
(engines for sessions, logging, templates)
● Serializers (JSON, YAML, XML)
● Route filters (before, after, before_template)
31. Dancer::Plugin::Ajax
ajax '/check_for_update' => sub {
# some ajax code
};
● Pass if X-Request-With not “XMLHttpRequest”
● Disable the layout
● The action built is a POSTrequest
32. Dancer::Plugin::DBIC
● DBIC (DBIx::Class) – a sophisticated ORM
● Configure the connection in the config file
● Make the ResultSets available in routes
33. Dancer::Plugin::Database
● Database(s) connection in Dancer
get '/widget/view/:id' => sub {
my $sth = database>prepare(
'select * from widgets where id = ?'
);
$sth>execute( params>{id} );
template display_widget => {
widget => $sth>fetchrow_hashref,
};
};
34. Even more plugins
● Dancer::Plugin::WebSocket
● Dancer::Plugin::FlashMessage
● Dancer::Plugin::Auth::Twitter
● Dancer::Plugin::MobileDevice
● Dancer::Plugin::Feed
● Dancer::Plugin::Redis
35. In culmination
Dancer is beautiful and fun
