Presentation delivered at Oracle Open World 2019 (San Francisco, California)
Abstract: This session walks through everything you need to know to move your databases to Oracle Cloud, based on the speakers’ own experience in doing it, focused on Oracle Exadata cloud services. The speakers review the configuration required, common problems they had to resolve in the process of having several TB databases running in Oracle Cloud, and operational tasks after they were running there.
Oracle Database features every developer should know aboutgvenzl
This presentation highlights some Oracle Database features that make developers more productive when using Oracle Database. The slide deck does only contain a sample of many useful developer features inside the Oracle Database. Developers should always refer to the Oracle Database Development Guide (https://docs.oracle.com/en/database/oracle/oracle-database/18/adfns/index.html)
This slide deck what co-produced with https://twitter.com/sqlmaria
In this session, we looked at five things you might not know about the Oracle Database or might have forgotten. For each topic, I explained the functionality and demonstrated the benefits using real-world examples. The topics covered apply to anyone running Oracle Database 11g and up, including Standard Edition, with only a few minor exceptions.
Just about anyone can write a basic SQL query for a table. Not everyone can write a good query though - that takes practice and knowing how to understand what the optimizer is doing with the query. Learn the basics of query optimization so you keep your application engaging the user rather then showing the progress bar as they wait on the database.

Database basics for new-ish developers -- All Things Open October 18th 2021Dave Stokes
Do you wonder why it takes your database to find the top five of your fifty six million customers? Do you really have a good idea of what NULL is and how to use it? And why are some database queries so quick and others frustratingly slow? Relational databases have been around for over fifty years and frustrating developers for at least forty nine of those years. This session is an attempt to explain why sometimes the database seems very fast and other times not. You will learn how to set up data (normalization) to avoid redundancies into tables by their function, how to join two tables to combine data, and why Structured Query Language is so very different than most other languages. And you will see how thinking in sets over records can greatly improve your life with a database.

Longhorn PHP - MySQL Indexes, Histograms, Locking Options, and Other Ways to ...Dave Stokes
Slow query? Add an index or two! But things are suddenly even slower! Indexes are great tools to speed data lookup but have overhead issues. Histograms don’t have that overhead but may not be suited. And how you lock rows also effects performance. So what do you do to speed up queries smartly? This is a clear, detailed look at what you can do to really speed up your queries in a logical, orthogonal process. Updated Presentation for Longhorn PHP Conference October 14th, 2021

# Internet Security: Safeguarding Your Digital World
In the contemporary digital age, the internet is a cornerstone of our daily lives. It connects us to vast amounts of information, provides platforms for communication, enables commerce, and offers endless entertainment. However, with these conveniences come significant security challenges. Internet security is essential to protect our digital identities, sensitive data, and overall online experience. This comprehensive guide explores the multifaceted world of internet security, providing insights into its importance, common threats, and effective strategies to safeguard your digital world.
## Understanding Internet Security
Internet security encompasses the measures and protocols used to protect information, devices, and networks from unauthorized access, attacks, and damage. It involves a wide range of practices designed to safeguard data confidentiality, integrity, and availability. Effective internet security is crucial for individuals, businesses, and governments alike, as cyber threats continue to evolve in complexity and scale.
### Key Components of Internet Security
1. **Confidentiality**: Ensuring that information is accessible only to those authorized to access it.
2. **Integrity**: Protecting information from being altered or tampered with by unauthorized parties.
3. **Availability**: Ensuring that authorized users have reliable access to information and resources when needed.
## Common Internet Security Threats
Cyber threats are numerous and constantly evolving. Understanding these threats is the first step in protecting against them. Some of the most common internet security threats include:
### Malware
Malware, or malicious software, is designed to harm, exploit, or otherwise compromise a device, network, or service. Common types of malware include:
- **Viruses**: Programs that attach themselves to legitimate software and replicate, spreading to other programs and files.
- **Worms**: Standalone malware that replicates itself to spread to other computers.
- **Trojan Horses**: Malicious software disguised as legitimate software.
- **Ransomware**: Malware that encrypts a user's files and demands a ransom for the decryption key.
- **Spyware**: Software that secretly monitors and collects user information.
### Phishing
Phishing is a social engineering attack that aims to steal sensitive information such as usernames, passwords, and credit card details. Attackers often masquerade as trusted entities in email or other communication channels, tricking victims into providing their information.
### Man-in-the-Middle (MitM) Attacks
MitM attacks occur when an attacker intercepts and potentially alters communication between two parties without their knowledge. This can lead to the unauthorized acquisition of sensitive information.
### Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) Attacks
