This document contains slides from a lecture on getting started with C++ programming. It discusses the basics of C++ including classes, scope, input/output, and memory management. The slides provide examples of defining classes with public, private, and protected components. It also demonstrates defining classes in a single file versus splitting the class definition and implementation across multiple files.
Presentation of features already voted into C++20 Standard Draft in Toronto, Albuquerque, and Jacksonville ISO C++ Committee Meetings as well as the overview of other really promising proposals that have high chances to arrive in C++20.
New and delete are a thing of the past, with the new features in C++14 and beyond (such as smart pointers and move semantics) memory management is easier and safer. Learn how to use the new constructs of C++14 and beyond to create, move, and free objects in a safer and more efficient manner.

The Titanium OpenGL Module (Ti.OpenGL) opens the door to sophisticated graphics development for the Titanium programmer by exposing the entire OpenGL ES 1 and ES 2 graphics API to the Ti Javascript environment. The Ti.OpenGL view extends Ti.UI.View with a graphics rendering canvas that is easily managed within the Titanium view hierarchy. In addition, the module provides a databuffer object to hold large datasets and mitigate any inefficiency that arises from modeling datasets in Javascript.
This talk demonstrates the pragmatics of building sophisticated graphics displays using Ti.OpenGL in both ES 1 and ES 2. It will reveal several reusable design abstractions that take advantage of features of the Javascript environment. Among the topics to be covered are:
- OpenGL basic setup and animation
- Use of databuffers for attribute and index arrays
- Connecting databuffers and vertex buffer objects (vbo’s)
- Using external resources (textures, shaders, etc.)

In this webinar, Michael DeSa will provide you with a detailed overviwe of Alert Handlers with Kapacitor. An AlertNode can trigger an event of varying severity levels, and pass the event to alert handlers. Different event handlers can be configured for each AlertNode. Some handlers like Email, HipChat, Sensu, Slack, OpsGenie, VictorOps, PagerDuty, Telegram and Talk have a configuration option 'global' that indicates that all alerts implicitly use the handler.

MongoDB is the trusted document store we turn to when we have tough data store problems to solve. For this talk we are going to go a little bit off the path and explore what other roles we can fit MongoDB into. Others have discussed how to turn MongoDB’s capped collections into a publish/subscribe server. We stretch that a little further and turn MongoDB into a full fledged broker with both publish/subscribe and queue semantics, and a the ability to mix them. We will provide code and a running demo of the queue producers and consumers. Next we will turn to coordination services: We will explore the fundamental features and show how to implement them using MongoDB as the storage engine. Again we will show the code and demo the coordination of multiple applications.

Programming Sideways: Asynchronous Techniques for AndroidEmanuele Di Saverio
Android apps need to respond fast, support highly parallel execution and multi component architecture.
Learn some tricks of the trade for these problems!
as presented at www.mobileconference.it (2013 edition)
In software engineering, the right architecture is essential for robust, scalable platforms. Wix has undergone a pivotal shift from event sourcing to a CRUD-based model for its microservices. This talk will chart the course of this pivotal journey.
Event sourcing, which records state changes as immutable events, provided robust auditing and "time travel" debugging for Wix Stores' microservices. Despite its benefits, the complexity it introduced in state management slowed development. Wix responded by adopting a simpler, unified CRUD model. This talk will explore the challenges of event sourcing and the advantages of Wix's new "CRUD on steroids" approach, which streamlines API integration and domain event management while preserving data integrity and system resilience.
Participants will gain valuable insights into Wix's strategies for ensuring atomicity in database updates and event production, as well as caching, materialization, and performance optimization techniques within a distributed system.
Join us to discover how Wix has mastered the art of balancing simplicity and extensibility, and learn how the re-adoption of the modest CRUD has turbocharged their development velocity, resilience, and scalability in a high-growth environment.

SOCRadar Research Team: Latest Activities of IntelBrokerSOCRadar
The European Union Agency for Law Enforcement Cooperation (Europol) has suffered an alleged data breach after a notorious threat actor claimed to have exfiltrated data from its systems. Infamous data leaker IntelBroker posted on the even more infamous BreachForums hacking forum, saying that Europol suffered a data breach this month.
The alleged breach affected Europol agencies CCSE, EC3, Europol Platform for Experts, Law Enforcement Forum, and SIRIUS. Infiltration of these entities can disrupt ongoing investigations and compromise sensitive intelligence shared among international law enforcement agencies.
However, this is neither the first nor the last activity of IntekBroker. We have compiled for you what happened in the last few days. To track such hacker activities on dark web sources like hacker forums, private Telegram channels, and other hidden platforms where cyber threats often originate, you can check SOCRadar’s Dark Web News.

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.

Anatomy of a Program
class FooBar {
private:
char a;
int variable;
protected:
int anotherVariable;
public:
void method1() { }
void method2() { }
};
int x;
int main(){

§ Data and the operations,
that manipulate data, are
encapsulated in classes.
§ You can defined public,
private, and protected
components. And,
encapsulated data can
only be accessed (from
outside the class)
through their interface
(operations defined as
public)

Level of Abstraction
In Java,
attributes and methods are always in
one file.
Java have all related information in
one place.
In C++,
implementations of member functions
can be in the same file than the
class definition (for short
functions) or outside of the class
definition.
C++ argument: structurally clearer
to separate implementation from
definition
