Although EXPLAIN FORMAT=JSON was first presented a long time ago, there still aren't many resources that explain how and why to use it. The most advertised feature is visual EXPLAIN in MySQL Workbench, but this format can do more than create nice pictures. It prints additional information that can't be found in good old tabular EXPLAIN, and can help to solve many tricky performance issues. In this session, I will not only describe which additional information we can get with the new syntax, but also provide examples showing how to use it to diagnose production issues.

Optimizing Queries with Explain
Optimizing Queries with ExplainMYXPLAIN The document discusses how to use EXPLAIN to optimize SQL queries. EXPLAIN shows how tables are joined, indexes used, and records examined. It returns information like the number of tables, join types, and data access methods. The fastest strategies are const, which uses a primary or unique key to lookup at most one value, and eq_ref, which joins on a unique index. EXPLAIN helps identify inefficient queries to improve performance.

MySQL Indexes
MySQL IndexesAnton Zhukov MySQL uses indexes to optimize queries and improve performance. Indexes are stored in b-trees to keep data sorted and allow fast searches, inserts and deletions. The selectivity of an index, or the ratio of unique values within a column, determines how effectively the index can reduce the result set size. Highly selective columns on frequently queried subsets of rows make the best candidates for indexes. MySQL can use indexes to optimize data lookups, sorting, avoiding full table scans, and certain aggregation functions.
Explaining the Postgres Query Optimizer (Bruce Momjian)
Explaining the Postgres Query Optimizer (Bruce Momjian)Ontico The document discusses how the Postgres query optimizer works. It explains that the optimizer determines the fastest method to execute SQL queries by interpreting them and generating optimal execution plans. It shows how the optimizer may choose different plans like index scans, bitmap index scans, or sequential scans based on factors like the distribution of data and how common or rare a value is in the table. It demonstrates this behavior using the EXPLAIN command on different sample queries against a temporary table.

Introduction to MySQL Query Tuning for Dev[Op]sSveta Smirnova To get data, we query the database. MySQL does its best to return requested bytes as fast as possible. However, it needs human help to identify what is important and should be accessed in the first place.
Queries, written smartly, can significantly outperform automatically generated ones. Indexes and Optimizer statistics, not limited to the Histograms only, help to increase the speed of the query a lot.
In this session, I will demonstrate by examples of how MySQL query performance can be improved. I will focus on techniques, accessible by Developers and DevOps rather on those which are usually used by Database Administrators. In the end, I will present troubleshooting tools which will help you to identify why your queries do not perform. Then you could use the knowledge from the beginning of the session to improve them.

How negative thinking holds us back from achieving our best.
Phing
PhingJeremy Coates Phing is a PHP-based build system similar to Apache Ant that allows developers to automate tasks like testing, deployment, and reporting. It can run tasks like code quality checks, unit testing, database deployment, linting, and generating documentation. Phing uses XML build files to define targets and tasks. Example tasks shown include cleaning, preparing, and deploying to staging and live environments. Phing can also integrate with continuous integration tools like Jenkins to run automated builds and tests regularly.

The Uncertainty Principle
The Uncertainty PrincipleJeremy Coates 1. The document discusses the uncertainty principle and how it is impossible to know both the precise position and momentum of a particle at the same time.
2. It argues that software development is a learning process where uncertainty decreases over time as knowledge increases. Early decisions should not dominate later development when understanding is greatest.
3. The key ideas are that uncertainty should be used as an indicator to consider options and defer commitment, and that the best way to achieve flexibility is to understand specific examples rather than trying to account for all possible general cases.
Exploiting Php With Php
Exploiting Php With PhpJeremy Coates Arpad Ray's PHPNW08 slides:
Looking at websites from the perspective of potential attackers is a useful technique not only for security professionals.
This talk demonstrates how to use simple PHP scripts to exploit many common security holes in PHP applications, hopefully giving developers a deeper understanding of what it is they are protecting against.
* Getting around common precautions against SQL injection
* Free spam with SMTP injection
* Making a malicious website to exploit PHP sessions
* The holes every attacker hopes for
* Making use of a newly exploited website
What's new, what's hot in PHP 5.3
What's new, what's hot in PHP 5.3Jeremy Coates Johannes Schlüter's PHPNW08 slides:
The current PHP version, PHP 5.3 introduced a multitude of new language features, most notably namespaces and late static binding, new extensions such as phar, as well as numerous other improvements. Even so, this power-packed release boasts better performance than older PHP releases. This talk will give you a good overview about PHP 5.3 and show some less known features in detail.
Kiss Phpnw08
Kiss Phpnw08Jeremy Coates Derick Rethans' PHPNW08 key note slides:
One of PHP’s strengths has always been its low barrier-of-entry. It’s also one of its weaknesses however. In this keynote I will talk about the first steps of getting to know PHP, its community and developers. Of course times have changed now, and we are in the Web 2.0 era now, but the KISS principle still applies; for application design, for UI design and for server set-ups. I will also take you to the application development side of the KISS principle, with simpler architectures you can more easily make powerful complex applications.
Regex Basics
Regex BasicsJeremy Coates Ciarán Walsh's PHPNW08 slides:
In the right hands regular expressions can be a powerful tool, but it’s also far too easy for them to be used badly, or in the wrong situations.
This talk will kick off with a look at alternatives to regular expressions, for when the power of pattern matching is not required, and will also go over some cases when there are better alternatives available.
Then there will be a brief refresher on pattern syntax and some general tips and tricks to help when constructing regular expressions, before we go on to look at some situations where the use of pattern matching is a good fit, how to solve some common problems, and some common pitfalls when writing patterns.
Search Lucene
Search LuceneJeremy Coates Zoe Slattery's slides from PHPNW08:
The ability to store large quantities of local data means that many applications require some form of text search and retrieval facility. From the point of view of the application developer there are a number of choices to make, the first is whether to use a complete packaged solution or whether to use one of the available information libraries to build a custom information retrieval (IR) solution. In this talk I’ll look at the options for PHP programmers who choose to embed IR facilities within their applications.
For Java programmers there is clearly a good range of options for text retrieval libraries, but options for PHP programmers are more limited. At first sight for a PHP programmer wishing to embed indexing and search facilities in their application, the choice seems obvious - the PHP implementation of Lucene (Zend Search Lucene). There is no requirement to support another language, the code is PHP therefore easy for PHP programmers to work with and the license is commercially friendly. However, whilst ease of integration and support are key factors in choice of technology, performance can also be important; the performance of the PHP implementation of Lucene is poor compared to the Java implementation.
In this talk I’ll explain the differences in performance between PHP implementation of Lucene and the Java implementation and examine the other options available to PHP programmers for whom performance is a critical factor.
Introduction to Version Control
Introduction to Version ControlJeremy Coates Version control is a method for centrally storing files and keeping a record of changes made by developers. It allows tracking who made what changes and when. This allows developers to back up their work, track different versions of files, merge changes from multiple developers, and recover old versions if needed. Centralized version control systems like Subversion store all files in a central repository that developers check files out from and check changes back into. Subversion allows viewing changes between versions, rolling back changes, and recovering old project versions with a single version number across all files.

Is AI just another technology, or does it fundamentally change the way we live and think?
Every technology has a direct impact with micro-ethical consequences, some good, some bad. However more profound are the ways in which some technologies reshape the very fabric of society with macro-ethical impacts. The invention of the stirrup revolutionised mounted combat, but as a side effect gave rise to the feudal system, which still shapes politics today. The internal combustion engine offers personal freedom and creates pollution, but has also transformed the nature of urban planning and international trade. When we look at AI the micro-ethical issues, such as bias, are most obvious, but the macro-ethical challenges may be greater.
At a micro-ethical level AI has the potential to deepen social, ethnic and gender bias, issues I have warned about since the early 1990s! It is also being used increasingly on the battlefield. However, it also offers amazing opportunities in health and educations, as the recent Nobel prizes for the developers of AlphaFold illustrate. More radically, the need to encode ethics acts as a mirror to surface essential ethical problems and conflicts.
At the macro-ethical level, by the early 2000s digital technology had already begun to undermine sovereignty (e.g. gambling), market economics (through network effects and emergent monopolies), and the very meaning of money. Modern AI is the child of big data, big computation and ultimately big business, intensifying the inherent tendency of digital technology to concentrate power. AI is already unravelling the fundamentals of the social, political and economic world around us, but this is a world that needs radical reimagining to overcome the global environmental and human challenges that confront us. Our challenge is whether to let the threads fall as they may, or to use them to weave a better future.
