How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

The presentation culminates in a live demonstration. We'll showcase the manipulation of Galileo's Open Service pilot signal, simulating an attack on various software and hardware systems. This practical demonstration serves to highlight the potential consequences of unaddressed vulnerabilities, emphasizing the importance of offensive security practices in safeguarding critical infrastructure.
Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

Bram Verhoef, Head of Machine Learning at Axelera AI, presents the “How Axelera AI Uses Digital Compute-in-memory to Deliver Fast and Energy-efficient Computer Vision” tutorial at the May 2024 Embedded Vision Summit.
As artificial intelligence inference transitions from cloud environments to edge locations, computer vision applications achieve heightened responsiveness, reliability and privacy. This migration, however, introduces the challenge of operating within the stringent confines of resource constraints typical at the edge, including small form factors, low energy budgets and diminished memory and computational capacities. Axelera AI addresses these challenges through an innovative approach of performing digital computations within memory itself. This technique facilitates the realization of high-performance, energy-efficient and cost-effective computer vision capabilities at the thin and thick edge, extending the frontier of what is achievable with current technologies.
In this presentation, Verhoef unveils his company’s pioneering chip technology and demonstrates its capacity to deliver exceptional frames-per-second performance across a range of standard computer vision networks typical of applications in security, surveillance and the industrial sector.

Imagine an IoT processing system that is already quite mature and production-ready and for which client coverage is growing and scaling and performance aspects are life and death questions. The system has Redis, MongoDB, and stream processing based on ksqldb. In this talk, firstly, we will analyze scaling approaches and then select the proper ones for our system.
Essentials of Automations: Exploring Attributes & Automation ParametersSafe Software
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

10. UR SHIPMENT OF FAIL HAS ARRIVED
Thursday, January 15, 2009
11. What is
deployment?
Thursday, January 15, 2009
12. A Series of
Dependencies
• Rails v2.2.2, v1.2.3, etc
• Ruby/Ruby Enterprise
• Apache/Nginx
• Passenger/Thin/Mongrel
• MySQL/PostgreSQL
• system user
Thursday, January 15, 2009
13. A Series of
Dependencies
• rmagick
• libmagick10 libmagick9-dev
• thinking-sphinx
• compile by hand
• memcached
• libmemcached, rubygem, service
Thursday, January 15, 2009
21. Decisions We’ve
Made For You
• Ubuntu
• Apache
• Passenger
• Ruby Enterprise Edition
• MySQL
• ‘rails’ user
• /srv/rails
Thursday, January 15, 2009
22. Look at all the choices
I’m not making
class Moonshine::Manifest::Rails < Moonshine::Manifest
requires [
:user,
:ruby,
:rubygems,
:db,
:web,
:rails,
:deploy
]
provides :user, 'rails'
provides :ruby, 'enterprise_ruby'
provides :rubygems, 'enterprise_rubygems'
provides :db, 'mysql'
provides :web, 'apache2'
provides :rails, 'passenger'
provides :deploy, 'git'
end
Thursday, January 15, 2009
25. Answer some questions
• application name
• git repo
• branch to deploy from
• user to create
• generates SSH key for git host
• server ‘tags’
Thursday, January 15, 2009
26. Moonshine goes to
work
• clones your repo
• parses and executes generated moonshine
manifests
• installs needed gems
• install dependencies
• migrates your db
• deploys your app
Thursday, January 15, 2009
27. Gem Dependencies
gem_dependencies do |gem|
#lots of dependencies are specified for you already
#gem.packages 'mysql', %w(mysql‐dev libmysqlclient5‐dev)
#gem.packages 'rmagick', %w(ruby‐dev libmagick9‐dev)
#...
#can specify a mini‐manifest to satisfy before
#installation of this gem
gem.custom 'urgem' do |puppet|
puppet.file '/file/needed/by/ur/gem',
:ensure => 'present',
:content => 'foo'
build_tarball('http://whatever.com/lib‐something.tgz')
end
end
Thursday, January 15, 2009
29. On subsequent runs
• updates your repo
• parses and executes updated moonshine
manifests
• verifies needed gems
• verifies dependencies
• migrates your db
• deploys your app
Thursday, January 15, 2009
30. Deployment is now...
• Reproducible
• Verified from top-bottom on each deploy
• Versionable with your application
• same commit can contain, for example,
thinking sphinx and installation of the
sphinx searchd daemon
• DRY
Thursday, January 15, 2009
31. Puppet Based
class MysqlMain < Moonshine::Manifest
puppet.file '/etc/my.cnf',
:ensure => 'present',
:content => """
[client]
port = 3306
socket = /var/run/mysqld/mysqld.sock
[mysqld]
default‐character‐set = utf8
key_buffer = 16M
max_allowed_packet = 16M
thread_stack = 128K
thread_cache_size = 8
"""
end
Thursday, January 15, 2009
32. But Ruby
class MysqlMain < Moonshine::Manifest
puppet.file '/etc/my.cnf',
:ensure => 'present',
:content => ArbitraryKlass.arbitrary_function('foo')
end
Thursday, January 15, 2009
33. Modular
UrClass < Moonshine::Manifest::Rails < Moonshine::Manifest
• easy to create your own reusable
server manifests
• extend existing ones with modules
Thursday, January 15, 2009
34. Sample ‘plugin’
module MoonshineOrderedPackages
def packages(array_or_name, params = {})
package_array = array_or_name.to_a
params = {
:ensure => 'installed'
}.merge(params)
package_array.each_with_index do |name,index|
#ensure packages are installed in order given
package_params = params
if package_array[index+1]
package_params.merge({
:before => package(package_array[index+1])
})
end
puppet.package name.to_s, package_params
end
end
end
Moonshine::Manifest::Rails.send(:extend, MoonshineOrderedPackages)
