Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

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.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
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).

1. GREEN COMPUTING
References
[1] DIVYA S, "GREEN COMPUTING," "technogreen" 2013.
Green computing or green IT, refers
to environmentally sustainable
computing or IT. In the article
Harnessing Green IT: Principles and
Practices, San Murugesan defines
the field of green computing as "the
study and practice of designing,
manufacturing, using, and disposing
of computers, servers, and
associated subsystems—such as
monitors, printers, storage devices,
and networking and communications
systems — efficiently and
effectively with minimal or no
impact on the environment.
The goals of green computing are
similar to green chemistry; reduce
the use of hazardous materials,
maximize energy efficiency during
the product's lifetime, and promote
the recyclability or biodegradability
of defunct products and factory
waste. Research continues into key
areas such as making the use of
computers as energy-efficient as
possible, and designing algorithms
and systems for efficiency-related
computer technologies.
The term "technology" refers to
the application of knowledge for
practical purposes.
The field of "green technology"
encompasses a continuously
evolving group of methods and
materials, from techniques for
generating energy to non-toxic
cleaning products.
The present expectation is that this
field will bring innovation and
changes in daily life of similar
magnitude to the "information
technology" explosion over the last
two decades. In these early stages, it
is impossible to predict what "green
technology" may eventually
encompass.
The goals that inform developments
in this rapidly growing field include:
Sustainability - meeting the needs of
2. society in ways that can continue
indefinitely into the future without
damaging or depleting natural
resources. In short, meeting present
needs without compromising the
ability of future generations to meet
their own needs.
"Cradle to cradle" design - ending
the "cradle to grave" cycle of
manufactured products, by
creating products that can be fully
reclaimed or re-used.
WHAT
IS
COMPUTING?
GREEN
• Green computing or green
IT, refers to environmentally
sustainable computing or IT.
• It is "the study and practice of

ROAD
TO
COMPUTING:
GREEN
• Green Use
• Green Disposal
• Green Design
• Green Manufacturing
APPROACHES TO GREEN
COMPUTING:
DISPLAY:
• LCD displays: use a CCF bulb
• LED displays: use an array of
LEDs
• LCD monitors uses 3 times
less when active, and 10 times
less energy when in sleep
mode.
• LCDs are up to 66% more
energy efficient.
• LCDs are also smaller in size
and weight.
• 21" CRT typically uses more
than 120W.
IT EQUIPMENT RECYCLING:
• If you can extend the working
life of your IT products, you
reduce the environmental
consequences of mining,
manufacture, packaging,
shipping and disposal.
• Many organizations, including
some manufacturers
themselves, are willing to take
equipment back and recycle
the components into new
products.

Remote Conferencing &
Telecommuting Strategies:
Given recent jumps in fuel costs and
greater awareness of harm caused by
greenhouse gas emissions, many
companies wish to reduce travel to
cut costs and decrease negative
impact on the environment.
The initiatives in this study consist
of the following:
• Remote Conferencing &
Collaboration.
• Video-conferencing and
teleconferencing.
4. INDUSTRIAL
IMPLEMENTATION:
• Their “Plant a tree for me”
project can offset a customer’s
carbon emissions for only
three dollars.
• Blackle(74~59 wt)(saves
750mw)
• Fit-PC(compact, quiet and
green)
CAUSES FOR GREEN IT:
• Use lot of Electricity
• Zonbu Computer
• Creates lots of toxic waste
• Sunray thin client
• Impact of Electricity to the
Environment
• Impact of Toxic waste to the
Environment
ENERGY USAGE PROFILE
(EUP):
• CPU uses 120 Watts
• CRT uses 150 Watts
– 8 hours of usage, 5 days
a week = 562 kWatts
STEPS BY DELL:
• Their free world-wide product
recycling program allows user
to properly dispose their
product safely.
• if the computer is
left on all the
time without
proper power
saver modes, this
can lead to 1,600
KWatts
• Energy use
comes from
5. – electrical current to run
the CPU, motherboard,
memory
consumer electronics device,
including cables. When
disposed off improperly, these
materials contain elements
that work their way into our
water table. The elements are
also rendered non-reusable as
they are blended in with other
waste and lost.
– running the fan and
spinning the disk(s)
– monitor (CRTs
consume more power
than any other
computer component)
– printers
TOXICITY:
•
Metals like Lead, Mercury,
Cadmium, Hexavalent
Chromium, Plastics, tin,
copper, carbon and aluminum
• Iron, Silicon, Lithium, Zinc,
Gold, Sulphur
E-WASTE:
•
Electronic waste (eWaste)
is one of the most controllable
pieces of the waste stream.
Recycling eWaste is easy;
recycling eWaste normally
and ethically takes a bit more
work.
• What is electronic waste? Any
cell phone, computer,
monitor, printer, CD, battery,
television or other business or
APPROACHES TO GREEN
COMPUTING:
•
Algorithmic Efficiency
• Power Management
• Video Card
• Telecommuting
REDUCING ENERGY
CONSUMPTION:
•
Turn off the computer
when not in use, even if just
for an hour
• Turn off the monitor when not
in use (as opposed to
running a screen saver)
• Use power saver mode
6. – in power saver mode,
the top item is not
necessary, but screen
savers use as much
electricity as any
normal processing, and
the screen saver is not
necessary on a flat
panel display
• Use motherboard video output
- typically low 3D
performance and low power.
• Select a CPU based on low
idle power, average wastage
or performance per watt.
REFURBISH:
•
• Use hardware/software with
the Energy Star label
– Energy Star is a “seal
of approval” by the
Energy Star
organization of the
government (the EPA)
• Don’t print unless necessary
and you are ready
• Use LCDs instead of CRTs as
they are more power efficient.
VIDEO CARD:
A fast CPU may be the largest
power consumer in a computer.
Energy efficient display options
include:
• No video card - use a shared
terminal, shared thin client,
or desktop sharing software if
display required.
rather than discarding
your computer when the next
generation is released, just get
a new CPU and memory chips
– upgrade rather than replace
while you will still be
discarded some components,
you will retain most of the
computer system (e.g.,
monitor, the system unit
housing, cables)
RECYCLE:
•
Computer monitors (CRTs)
contain an average of 4 lbs. of
lead, a lot of reusable glass,
chromium and mercury. All of
these elements can be
extracted and reused. For
example, a recycler can takes
the glass from old monitors,
and sends them to
manufacturing for use on flat
screen monitors and TVs.
• CDs/DVDs contain gold,
glass, plastic, nickel and other
elements that are completely
recoverable and reusable.
7. • Batteries – everything from
the batteries that power your
phone, laptop, and mouse can
be recycled, whether singleuse or rechargeable.
• Time-Based Power over
Ethernet (Poe)
• Wi-Fi Scheduler
• Share Port
• LCD Standby
GREEN WEB SURFING:
• Power Saving by Hard Drives
Hibernation
• Smart FAN
ADVANTAGES:
•
BEING
GREEN WITH YAHOO
GREENER
FIREFOX SURFING
Both green computing and
hardware disposal focus on
being green to help have less
of an impact on our
environment.
• Recycling like NewTech
disassembles and reuses parts
from old computers to build
new, better ones, without just
dumping them in a landfill.
CONCLUSION:
GREEN TECHNOLOGIES:
•
Power Saving by Link Status
• Power Saving by Cable
Length
• Green computing can lead to a
lot of energy savings,
reduction in emission of co2
& CFC’s which leads to
environment protection.
• It also leads to serious cost
savings overtime.
