Design Patterns avec PHP 5.3, Symfony et PimpleHugo Hamon
Cette conférence présente deux grands motifs de conception : l'observateur et l'injection de dépendance. Ce sujet allie à la fois théorie et pratique. Le composant autonome EventDispatcher de Symfony ainsi que le conteneur d'injection de dépendance Pimple sont mis à l'honneur avec des exemples pratiques d'usage. Ces cas pratiques combinent du code de l'ORM Propel ainsi que le composant autonome Zend\Search\Lucene du Zend Framework 2
Persistence is one of the most important part in a PHP project. Persisting data to a database came with PHP/FI and its MySQL support. From native extensions and PHP4 database abstraction libraries to PDO and modern ORM frameworks, you will (re)discover how persistence has evolved during the last decade. This talk will also introduce the future of data persistence with the growing success of alternative storage engines.

Burn down the silos! Helping dev and ops gel on high availability websitesLindsay Holmwood
HA websites are where the rubber meets the road - at 200km/h. Traditional separation of dev and ops just doesn't cut it.
Everything is related to everything. Code relies on performant and resilient infrastructure, but highly performant infrastructure will only get a poorly written application so far. Worse still, root cause analysis in HA sites will more often than not identify problems that don't clearly belong to either devs or ops.
The two options are collaborate or die.
This talk will introduce 3 core principles for improving collaboration between operations and development teams: consistency, repeatability, and visibility. These principles will be investigated with real world case studies and associated technologies audience members can start using now. In particular, there will be a focus on:
- fast provisioning of test environments with configuration management
- reliable and repeatable automated deployments
- application and infrastructure visibility with statistics collection, logging, and visualisation
iPhone applications can often benefit by talking to a web service to synchronize data or share information with a community. Ruby on Rails, with its RESTful conventions, is an ideal backend for iPhone applications. In this session you'll learn how to use ObjectiveResource in an iPhone application to interact with a RESTful web service implemented in Rails. This session isn't about how to build web applications that are served up on the iPhone. It's about how to build iPhone applications with a native look and feel that happen to talk to Rails applications under the hood. The upshot is a user experience that transcends the device.

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.
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).

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

&char_filters=html_strip' -d 'this is a <b>test</b>'
$ curl -XGET localhost:9200/twitter/_analyze?text=this+is+a+test
36. Warmers
Index warming allows to run registered search
requests to warm up the index before it is available for
search.
Warmup searches typically include requests that require
heavy loading of data, such as faceting or sorting on
specific fields.
41. Status
The indices status API allows to get a comprehensive
status information of one or more indices.
$ curl -XGET localhost:9200/twitter/_status
$ curl -XGET localhost:9200/twitter,kimchy/_status
$ curl -XGET localhost:9200/_status
42. Stats
Indices level stats provide statistics on different
operations happening on an index.
$ curl -XGET localhost:9200/twitter/_stats
$ curl -XGET localhost:9200/twitter,kimchy/_stats
$ curl -XGET localhost:9200/_stats

specific caches associated with one ore more indices.
$ curl -XPOST localhost:9200/twitter/_cache/clear
$ curl -XPOST localhost:9200/twitter,kimchy/_cache/clear
$ curl -XPOST localhost:9200/_cache/clear
47. Cache Types
— filter
— field_data
— id_cache
$ curl -XPOST localhost:9200/twitter/_cache/clear?filter=true
cf. The filter cache will be cleared within 60 seconds.
48. Flush
The flush process of an index basically frees memory
from the index by flushing data to the index storage and
clearing the internal transaction log.
$ curl -XPOST localhost:9200/twitter/_flush
$ curl -XPOST localhost:9200/twitter,kimchy/_flush
$ curl -XPOST localhost:9200/_flush
49. Refresh
The refresh API allows to explicitly refresh one or more
index, making all operations performed since the last
refresh available for search.

$ curl -XPOST localhost:9200/twitter,kimchy/_refresh
$ curl -XPOST localhost:9200/_refresh
50. Optimize
The optimize process basically optimizes the index for
faster search operations.
The optimize operation allows to reduce the number of
segments by merging them.
$ curl -XPOST localhost:9200/twitter/_optimize
$ curl -XPOST localhost:9200/twitter,kimchy/_optimize
$ curl -XPOST localhost:9200/_optimize
