With the HTML5 age a lot of new features came to help developers to create amazing apps and amazing user experience, one of these features is called web socket which provides new powers under the HTTP protocol.
HTTP is one of the most widely used protocols in the world.
The version of HTTP 1.1, used to this day, was developed and described 18 years ago - 1999.
With the increasing complexity of web applications, the capabilities of HTTP 1.1 are already insufficient to provide increased demands on performance and responsiveness.
So in order to meet new requirements, HTTP must evolve. HTTP 2.0 is designed to make web applications faster, simple and reliable.
In this report I will tell about
- drawbacks of HTTP 1.1 and why we need a new version of HTTP.
- which advantages HTTP/2 offers in comparison with the previous version?
- how the new protocol affected the new version of SERVLET 4.0 and how we can use it.

This session covers Jetty 9’s scalability, stability, performance, and features such as the new HTTP client and how to configure Jetty for optimal production performance.
Проксирование HTTP-запросов web-акселератором / Александр Крижановский (Tempe...Ontico

Вы поставили HTTP-акселератор перед вашим web-сервером для ускорения отдачи контента, но запросы пользователей по-прежнему отдаются с большой задержкой, а ресурсы сервера кажутся незагруженными. А, может, после того, как поставили
web-акселератор, web-приложение сломалось, да еще и так, что проблема воспроизводится редко, хуже того, о ней могут знать ваши пользователи, но не вы.
...
An overview of the HTTP protocol showing the protocol basics such as protocol versions, messages, headers, status codes, connection management, cookies and more.
But it still remains an overview without in-depth information. Also some key aspects are left out (because of limited time) such as authentication, content negotiation, robots, web architecture etc..
В докладе рассказывается о расширении для стека протоколов TCP/IP в ОС Linux, которое необходимо для того, чтобы HTTPS работал в том же стеке, что TCP и IP. DDoS-атаки такого типа как HTTP-флуд на уровне приложений, как правило, подавляются HTTP-акселераторами или балансировщиками нагрузки HTTP. Однако интерфейс сокетов Linux, используемый программным обеспечением, не дает той продуктивности, которая необходима при предельных нагрузках, вызванных DDoS-атаками. HTTP-серверы на базе стеков TCP/IP в пространстве пользователя становятся популярными в связи с увеличением их эффективности, но стеки TCP/IP представляют собой масштабный и сложный код, поэтому неблагоразумно реализовывать и исполнять его дважды — в пространстве пользователя и пространстве ядра. Стек TCP/IP в пространстве ядра хорошо интегрирован со многими мощными инструментами, например IPTables, IPVS, tc, tcpdump, которые недоступны для стека TCP/IP в пространстве пользователя или требуют сложных интерфейсов. Докладчик представит решение Tempesta FW, которое передает обработку HTTPS ядру. HTTPS встроен в стек TCP/IP Linux. Исполняя функцию межсетевого экрана HTTP, Tempesta FW устанавливает набор ограничений по скорости передачи и набор эвристических правил для защиты от таких атак как HTTPS-флуд и Slow HTTP.
Realizzare applicazioni Web con WebSocket, by Simone BordetCodemotion
Il protocollo WebSocket è ormai diventato un protocollo standard (RFC 6455), e ormai quasi tutti i browsers lo supportano. A differenza di HTTP permette una vera comunicazione bidirezionale tra client e server, permettendo di realizzare applicazioni molto scalabili. In questa sessione daremo uno sguardo al protocollo WebSocket e esamineremo come scrivere una applicazione web utilizzando WebSocket.
HTTP/2 and QUICK protocols. Optimizing the Web stack for HTTP/2 erapeychevi
The new HTTP/2 protocol which is going to replace HTTP 1.1 was finished on February. Together with it, QUIC is being developed rapidly. Discover why are they so important for the Web and how will they influence the way we optimize the Web stack for the HTTP/2 era.
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.
Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.
And...

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
