No Return: Beyond Transactions in Code and Life • Avdi Grimm

Jun 8 2020

At the root of catastrophes in both code and life lies a pervasive fallacy: the attempt to model processes as if they were transactions.\nJoin Avdi for an honest, sometimes raw retrospective on two decades of building a software development career. You’ll examine how personal philosophy impacts software design — and vice-versa. You’ll encounter the transactional fallacy and how it can hinder our attempts to build resilient systems. And you’ll explore how a narrative-oriented mindset can lead to both better code and a more joyful [...]

 David Beazley - Lambda Calculus from the Ground Up - PyCon 2019

Jun 4 2020

These days, programming style guides are all the rage. However, what if your style guide was so restrictive that it only gave you single-argument functions and nothing else? No modules, no classes, no control flow, no data structures, and not even any primitives like integers or regular expressions. Just functions. Could you actually program anything at all? Surprisingly, the answer is yes. In this tutorial, you'll learn how as you work through a ground-up derivation of the lambda calculus in Python.\n\nYou will learn nothing practically useful in this tutorial. No packaging. No tools. No libraries. No deployment. No magic Python programming techniques. And certainly learn nothing you would ever want to apply to a real project. You will, on the other hand, have a lot of fun, be completely amazed, and learn some foundational computer science that is a jumping off point for further explorations of functional programming, type theory, programming languages, and more.

 Union sql injection

Apr 7 2020

Year after year we find code injection in the OWASP 10. Despite this kind of vulnerability was discovered and reported more than twenty years ago, it seems not that easy to get rid of. SQL injections are one of these. Let's see some examples.

 PyCon Ireland 2019 - Unit & Integration Testing

Mar 24 2020

Testing is an important part of the software development life cycle, however we don't always stress the importance of it. There are dozens of different types of testing and each one has its own purpose. In order to clarify/revisit two of the more common testing types used by developers, here are some concept definitions and best practices around them.

 Security 101

Mar 18 2020

Security in IT is a gigantic huge topic that is impossible to fully cover. In addition, it constantly evolves and almost every single day appears a new vulnerability, malware or God damn knows what technique in order to compromise a system.

 Hacking Society

Mar 2 2020

Bruce Schneier, Security Technologist, Researcher and Lecturer, Harvard Kennedy School\n\nA computer security mindset is essential to understanding the security of complex technological systems. As we move into a world where all social, economic and political systems are to some extent technological, we need to extend this way of thinking. Come learn how to hack—and then defend—society’s core systems: elections, the market economy, lawmaking, tax policy, journalism and more.

 Kent Beck - 3X Explore/Expand/Extract

Feb 21 2020

Before you can evaluate a method, you have to understand its goals. Before you can evaluate a style of software engineering, you have to understand its goals. Quick execution of experiments? Rapid scaling in the face of unexpected bottlenecks? Sustained, profitable growth? Each goals requires a different style and yet we talk about software engineering as if it should be one thing. This talk introduces 3X and the ways software development, quality assurance, design, management, financing, planning, and staffing change depending on the goal of development. Consistently challenges software engineering dogma, promoting ideas like patterns, test-driven development, and Extreme Programming. Currently affiliated with Three Rivers Institute and Agitar Software, he is the author of many Addison-Wesley titles.
