This is a whirlwind tour of the FP land and is primarily meant for developers wanting to embark on their functional programming journey. Java is used to understand most of the concepts, however, where it falls short to explain certain concepts such as lazy evaluation, currying and partial function application, de-structuring and pattern-matching, Scala or Groovy or Clojure or even Haskell are used to demonstrate it.
New language from Google, static safe compiler, with GC and as fast as C++ or Java, syntax simpler then Python - 2 hour-long tutorial and you can start code.
In this talk Serhii will talk about Go, also known as Golang – an open source language developed at Google and used in production by companies such as Docker, Dropbox, Facebook and Google itself. Go is now heavily used as a general-purpose programming language that’s a pleasure to use and maintain. This introductory talk contains many live demos of basic language concepts, concurrency model, simple HTTP-based endpoint implementation and, of course, tests using build-in framework. This presentation will be interesting for backend engineers and DevOps to understand why Go had become so popular and how it might help to build robust and maintanable services.
Agenda of the presentation:
1. Go is not C, not Java, not anything
2. Rob Pike argument
3. Main ideas and basics
4. Concurrency model
5. Tools
6. Issues
This workshop was given at the NZITF conference 2018 in Wellington. The workshop covers Velociraptor, a modern DFIR endpoint monitoring and response tool.

More on bpftrace for MariaDB DBAs and Developers - FOSDEM 2022 MariaDB DevroomValeriy Kravchuk
bpftrace is a relatively new open source tracer for modern Linux (kernels 5.x.y) that may help to troubleshoot performance issues in production as well as to get insights on how software really works. I use it for a couple of years and would like to present more details on how to do it efficiently, including but not limited to adding user probes to different lines of the code inside functions, checking values of local variables and using bpftrace as a code coverage tool.
Over recent years, JavaScript has increasingly gained popularity, partly due to libraries that are developed to make JavaScript apps/effects easier to create for those who may not have fully grasped the core language yet.
While in the past it was a common argument that JavaScript was a basic language and was very ‘slap dash’ with no real foundation; this is no longer the case, especially with the introduction of high scale web applications and ‘adaptations’ such as JSON (JavaScript Object Notation).

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).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

3. ● function
● functions in go are types
○ functions behave as types in go
○ use like any other type
■ declare them as variables
■ pass functions around just as you'd pass types around
■ pass functions just like any other argument / parameter
● pass them into functions as arguments
● return them from functions
■ declare functions inside other functions
○ similar to JavaScript
14. ● Exercise
Write a function which takes an integer and returns two values:
● the integer divided by 2
● whether or not the integer is even (true, false)
For example
● half(1) should return (0, false)
● half(2) should return (1, true).
15. ● func expression - setting a variable equal to a function
this is not a func expression
this is our code before using a func expression
16. ● func expression
func expression
setting a variable equal to a func the scope of greeting is func main()
this is not a func expression
this is a func expression
https://play.golang.org/p/ux-KmWuN0Lf
20. ● closure
https://play.golang.org/p/p3kWmzBrLcx
closure
func main encloses func increment
closure helps us limit the scope of variables that are used by
multiple functions
without closure, for two or more funcs to have access to the
same variable, that variable would need to be package scope
func main is enclosing increment; increment is enclosing x
21. ● not closure
https://play.golang.org/p/H5tfU6SUocI
not using closure
closure helps us limit the scope of variables that are used
by multiple functions
without closure, for two or more funcs to have access to
the same variable, that variable would need to be package
scope
22. ● returning a func
https://play.golang.org/p/9t8CtlKWHwS
closure
closure helps us limit the scope of variables that are used
by multiple functions
without closure, for two or more funcs to have access to
the same variable, that variable would need to be package
scope
23. another func expression
setting a variable equal to a func
returning a func
(not part of func expression)
a func is returned
25. ● callback - passing a func as an argument
func visit takes two arguments
a slice of ints
another func
the callback
pass in the
slice of ints
https://play.golang.org/p/yyV7chHfFR6
30. ● another callback
“If you’ve done functional programming like Lisp or Haskell, this way of dealing with functions is super common; it’s an
approach to development; you get used to passing functions around. Go allows you to do that [passing functions around]
but it’s not the most common way of writing code. The more normal way you’d write code [for something like the code
above] would just be a simple for loop. For loops are easy to understand.”
~ Caleb Doxsey
32. ● recursion
● You can always use loops to solve any problem that
can be solved with recursion.
● Loops are more performant than recursion.
This is called the base case
33. ● defer - run this at the last possible moment
https://play.golang.org/p/QHsLIbenzxa
38. Review
● func main() {}
● calling a function
● greeting()
● parameters vs arguments
○ two params
○ variadic
■ …params
■ args...
● returns
○ named returns
○ multiple returns
● variable shadowing
● func expression
○ setting a variable equal to a function
○ greeting := func(){<code here>}
■ greeting’s type is func
● closure
○ one thing enclosing another
○ helps us limit scope of variables
● returning a func
○ functional programming
● callback
○ passing a func as an argument
● recursion
● defer
● the stack
○ the order in which functions are
called
