The document summarizes the main parts and proper use of a light microscope. It describes the objective lenses, how total magnification is calculated from the objective and eyepiece lenses, and how higher magnifications provide more detail but less visible area of the sample. Basic care and storage of microscopes is outlined. Methods for preparing slides with samples and coverslips are provided, as well as how stains can be used to highlight different cell structures. Questions at the end test the understanding of microscope use and calculations.

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!
DevOps and Testing slides at DASA ConnectKari Kakkonen
My and Rik Marselis slides at 30.5.2024 DASA Connect conference. We discuss about what is testing, then what is agile testing and finally what is Testing in DevOps. Finally we had lovely workshop with the participants trying to find out different ways to think about quality and testing in different parts of the DevOps infinity loop.
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.

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).

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

4. Total magnification:
Magnification = Objective lens X Eyepiece lens
e.g. What is the total
magnification if the objective lens
is twenty times (X20) and the
eyepiece lens five times (X5)?
Magnification = 20 X 5 = X100
5. As magnification increases, detail
increases but:
Onion cell 40x
Onion cell 100x
Onion cell 400x
less of the cell is seen
6. Caring for the microscope:
1. Do not let any liquids to come in contact
with the microscope.
2. Always store the microscope inside a box
after use.
3. Return the objective lens onto low power
after use.
4. Carry the microscope by the arm.
5. Use a soft clean tissue to wipe the lenses
9. Use of stains:
some parts of a plant cell can be clearly seen
when the cell is mounted in water
E.g. an Elodea leaf cell:
cell wall
several chloroplasts
are seen
10. other cell structures which are not so
obvious can often be shown up more clearly
by the addition of dyes called STAINS
METHYLENE BLUE
To stain animal cells
IODINE SOLUTION
To stain plant cells
11. A thin inner layer of
epidermis is peeled
off.
An onion is cut
into quarters.
One of the fleshy scale
leaves is removed.
Snapping leaf backwards
exposes the epidermis.
Epidermis is placed on
slide & covered with 2-3
drops of distilled water .
Coverslip is lowered.
A drop of stain is put at
one end of slide.

Stain is drawn over

piece of filter paper.
12. Questions
1. A pupil prepared a microscope slide of onion
cells using water.
Diagram A shows how the cells looked when
first seen with the microscope.
Diagram B shows their appearance after the
addition of another liquid.
What name is given to a liquid used to make
cell structures easier to see?
Stain
13. 2. The drawing shows the appearance of a
prepared slide.
What causes the ring shapes? (1)
Air bubbles trapped beneath the coverslip.
14. 3. This diagram shows the main parts of a
typical light microscope.
a) How is a glass slide held in position on the
stage?
By the clips.
15. b) Why must the specimen on the slide be in
the centre of the hole in the stage?
To allow light pass through the specimen.
c) Why does the nosepiece rotate?
To clip in position the required objective lens.
16. d) What is the mirror for?
To reflect light onto the specimen.
e) How can you control the amount of light
coming through the microscope?
By moving the diaphragm.
17. f) Explain how you would use the microscope
to look at a specimen under the low power.
1. Clipping slide by clips.
2. Placing the low power objective in position.
3. Moving the tube downwards while looking
from the side until objective lens is close to
the slide.
4. Using the coarse adjustment
knob, the tube is racked
upwards until image is focused.
18. g) If you had a specimen in focus under the low
power, how would you go on to look at it
under high power?
By using the fine adjustment knob.
19. h) Why should you never rack downwards with
the coarse focusing knob while you are
looking down the microscope?
Not to break the slide.
20. i) If the magnifying power of the eyepiece lens
is ten times (X10), and that of the low power
objective lens is four times (X4), what is the
total magnification of a specimen under low
power?
10 x 4 = x40
