spring-tutorial
This document provides a tutorial on summarizing the Spring Framework. It introduces the main packages in Spring Framework including the JDBC package for data access.

It provides code samples demonstrating how to perform queries, updates and retrieve results using these packages.
Jdbc oracle
JDBC is used to connect Java applications to databases. It uses drivers specific to each database type. The key steps are: 1) loading the driver, 2) defining the connection URL, 3) establishing a connection, 4) creating statements to execute queries or updates, 5) processing result sets, and 6) closing connections. Prepared statements are useful for queries executed multiple times to avoid recompilation. Transactions allow grouping statements that must all succeed or fail together to maintain database consistency.
Database programming

Es meetup slides
This document outlines an indexing design for Elasticsearch 7.x that addresses several requirements:
1. When a new index is created, all existing data is indexed.
2. Entities are reindexed when created or modified.
3. Switching indexes updates older indexes with new/modified data.
4. Load is distributed across nodes using Kafka queues and partitioning.
5. Schema changes trigger reindexing.
6. Unindexable messages are sent to a dead letter queue.
The design uses additional fields to track status, timestamps, partitions and schema versions. Messages are pushed to Kafka queues based on partition for indexing by multiple nodes. This ensures all data is indexed across failures.

Slick: Bringing Scala’s Powerful Features to Your Database Access
This talk will teach you how to use Slick in practice, based on our experience at EatingWell Media Group. Slick is a totally different (and better!) relational database mapping tool that brings Scala’s powerful features to your database interactions, namely: static-checking, compile-time safety, and compositionality.
Here at EatingWell, we have learned quite a bit about Slick over the past two years as we transitioned from a PHP website to Scala. I will share with you tips and tricks we have learned, as well as everything you need to get started using Slick in your Scala application.
I will begin with Slick fundamentals: how to get started making your connection, the types of databases it can access, how to actually create table objects and make queries to and from them. We will using these fundamentals to demonstrate the powerful features inherited from the Scala language itself: static-checking, compile-time safety, and compositionality. And throughout I will share plenty of tips that will help you in everything from getting started to connection pooling options and configuration for use at scale.
ADO .Net
This document discusses ADO.NET, which is a data access technology that allows applications to connect to and manipulate data from various sources. It describes the core ADO.NET objects like Connection, Command, DataReader, DataAdapter, DataSet and DataTable.

OQL querying and indexes with Apache Geode (incubating)
OQL is a SQL-like language for querying objects and data in Geode. It allows querying on any object attributes and invoking methods. Indexes can significantly improve query performance and avoid scanning entire regions. Different types of indexes include functional, functional compact, key, hash, and map indexes. Partitioned and colocated regions can be queried using functions or equijoins with some restrictions. General tips include matching from clauses to indexes, ordering AND filters by selectivity, and using hints to prefer indexes.
ADO.NET
ADO.NET is a data access technology that allows applications to connect to and manipulate data from various data sources. It provides a common object model for data access that can be used across different database systems through data providers. The core objects in ADO.NET include the Connection, Command, DataReader, DataAdapter and DataSet. Data can be accessed in ADO.NET using either a connected or disconnected model. The disconnected model uses a DataSet to cache data locally, while the connected model directly executes commands against an open connection.

Succession “Losers”: What Happens to Executives Passed Over for the CEO Job?
Succession “Losers”: What Happens to Executives Passed Over for the CEO Job? Stanford GSB Corporate Governance Research Initiative
This document summarizes a study of CEO succession events among the largest 100 U.S. corporations between 2005-2015. The study analyzed executives who were passed over for the CEO role ("succession losers") and their subsequent careers. It found that 74% of passed over executives left their companies, with 30% eventually becoming CEOs elsewhere. However, companies led by succession losers saw average stock price declines of 13% over 3 years, compared to gains for companies whose CEO selections remained unchanged. The findings suggest that boards generally identify the most qualified CEO candidates, though differences between internal and external hires complicate comparisons.Viewers also liked (9)

Каждый специалист в области баз данных уже знаком с Jsonb - одной из самых привлекательный фич PostgreSQL, позволяющей эффективно использовать документо-ориентированный подход без необходимости жертвовать консистентностью и возможностью использования проверенных временем подходов реляционных баз данных. Но как именно устроен этот тип данных, какие он имеет ограничения, и какие опасности (a.k.a грабли) можно незаметно для себя получить при работе с ним?
В докладе мы обсудим все эти вопросы, преимущества и недостатки использования Jsonb в различных ситуациях в сравнении с другими существующими решениями. Поговорим также о важных best practices (как писать компактные
запросы и как избежать распространенных и не очень проблем).

Cosa hanno in comune un mattoncino Lego e la backdoor XZ?
ABSTRACT: A prima vista, un mattoncino Lego e la backdoor XZ potrebbero avere in comune il fatto di essere entrambi blocchi di costruzione, o dipendenze di progetti creativi e software. La realtà è che un mattoncino Lego e il caso della backdoor XZ hanno molto di più di tutto ciò in comune.

A tale of scale & speed: How the US Navy is enabling software delivery from l...
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
