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!

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).

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

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.

Fall 201
2. Purpose:
The purpose of this laboratory is to become familiar with the D.C. operation of the
bipolar junction transistor (BJT), and a basic D.C. circuit using the BJT, namely, the current
mirror.
Equipment
External Multi-meter (for current measurements)
Regulated Power Supply
2N3904
Resistors
Introduction
The objective of this lab is to analyze the characteristics of Transistor. A transistor is a three-
terminal device which allows a small current to control a much larger current, thus achieving a
“current gain.” this lab, we focus on BJTs. The three terminals of a transistor are the base (usually
used as the control terminal), the emitter and the collector. There are three parts of the lab and
voltage across Rc is measured and current Rc is computed. Once the measurement is taken results are
plotted on the graphs and DC current Gain, Incremental resistance etc. are found.
A bipolar junction transistor is formed by joining three sections of semiconductors
withalternatively differentdoping. The middle section (base) is narrow and one of the other
tworegions (emitter) is heavily doped. Two variants of BJT are possible: NPN and PNP.
3. In NPN transistors,electron flow is dominant while PNP transistors rely mostly on the flow of
holes. Therefore,to zeroth order, NPN and PNP transistors behave similarly except the sign of
current andvoltages are reversed.! In practice, NPN transistors are much morepopular than PNP
transistors because electrons move faster in a semiconductor. As a result,a NPN transistor has a
faster response time compared to a PNP transistor.
The BJT is a three-terminal semiconductor device containing two pn junctions. If
checked with an ohmmeter it appears to be two diodes of opposite polarity connected in series.
However, unlike two series diodes, the BJT can be used to amplify

1. Connect the 2N3904 transistor up into the circuit as shown above; for your base and
Collectorresistors measure and record the exact values. (Set VBB and VCC voltages
4. set to zero).
2. Measure the voltage across RB while increasing the VBB supply voltage. Continue to
increase VBB until the voltage across RB reaches 1.65 volts in order to set up a base current
of 50 μA, which you can confirm by Ohm’s law.
3. Without changing VBB, increase VCC until the voltage from collector to emitter is +2.0
volts. Then, record the value of voltage across the resistor RC, and compute the collector
current (which equals the current through RC) by using Ohm’s Law applied to RC.
4. Without changing VBB, repeat step 3 by increasing VCC until the voltage from collector
to emitter is +4.0 volts. Record the value of voltage across the resistor RC, compute the
collector current as before, and enter the values into the table.
5. Repeat for VCC values of 6, 8 and 10 volts, and complete the table.
6. Next, reset VCC to a value of zero volts, and increase VBB until the voltage across RB is
3.3 volts, giving a base current of 100 μA.
7. Repeat steps 3, 4 and 5, completing the following table:
8. Next, reset VCC to a value of zero volts, and increase VBB until the voltage across RB is
4.95 volts, giving a base current of 150 μA.
9. Repeat steps 3, 4 and 5, completing the following table:
10. Plot the transistor characteristics on the following graph, using the values from the
5. three tables above. You should have three curves, labeled with IB = 50μA, 100μA and
150μA.
11. From your plotted curves, estimate the DC current gain (defined as βDC ≡ IC/IB) at a
value of VCE = 3 volts, for each value of base current (50μA, 100μA and 150μA).
12. Repeat step 11 at a value of VCE = 7.5 volts, for each value of base current (50μA,
100μA and 150μA).
13. Finally, for the case where IB = 150μA, compute the “incremental resistance”
ΔVCE/ΔIC = (VCE1 – VCE2)/(IC1 – IC2). Use the points at VCE = 10 volts and VCE = 2 volts,
on the IB = 150μA curve.

8. Discussion &Analysis:
One of the Task of the transistor is to provide DC current gain. The measurement shows
exactly that. In the circuit input current Ib and output current is Ic and DC current gain can be
found using Ic/Ib and its shown in the figure 5 for voltage 3 and voltage 7.5. Also the
incremental resistance is found by dividing change in voltage by change in current. I think
current gain does not depend on the Ib, because if Ib increase then Icincreases with similar ratio.
As seen in figure 5, as voltage increases current gain increases as well. Resistance value is
medium and that is 568 ohms.Since BJT are useful in discrete circuit design, we analyzedthestaticcharacteristicof
9. BJT.We measured and plotted the I-V curve for collector current and collector-emitter voltage, while keeping baseemitter voltage constant.
Conclusion
A single npn BJT was used to drive this differential amplifier. The collector current entering
the npn BJT will be the current source driving the differential amplifier. The transistor is good
component to get amplified current using a very small current. Dc current gain increases as Voltage
is increases. But Dc current gain for the same voltage with the different base current is same. Each
part has different base current but if DC current gain is found for same voltage on different curves it
will come out to be about the same.
