The stack is a group of memory locations used for temporary storage during program execution. Information is stored and retrieved from the stack using the PUSH and POP instructions in a LIFO manner. Subroutines allow a group of instructions to be called repeatedly from the main program. The CALL instruction stores the return address on the stack and transfers execution to the subroutine. The RET instruction retrieves the return address from the stack and transfers execution back to the main program.

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!
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.
Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

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).

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
2. The stack
The stack is a group of memory location in the
R/W memory that is used for temporary storage
of binary information during the execution of a
program
The stack is a LIFO structure.
– Last In First Out.
The starting location of the stack is defined by
loading a 16 bit address into the stack pointer
that spaced is reserved, usually at the top of
the memory map.
www.themeart.com 2
3. The stack
The stack normally grows backwards into
memory.
The stack can be initialized anywhere in the
user memory map , but stack is initialized at the
highest memory location so that there will not
be any interface with the program.
In 8085 microprocessor system the beginning of
the stack is defined in the program by using the
instruction
LXI SP,16 bit.
The LXI SP,a 16 bit state that load the 16 bit
address into the stack pointer register.
www.themeart.com 3
4. Information is stored and retrieved
from the stack
•The 8085 provide two instruction PUSH & POP for storing infor
mation on the stack and retrieving it back.
•Information in the register pairs stored on the stack in reverse
order by using the instruction PUSH.
• Information retrieved from the stack by using the instruction
POP.
•PUSH & POP both instruction works with register pairs only.
•The storage and retrieval of the content of registers on the
stack fallows the LIFO(Last-In-First-Out) sequence.
•Information in the stack location may not be destroyed until
new information is stored in that memory location
www.themeart.com 4
5. The PUSH Instruction
2000 LXI SP,2099H Load the stack pointer register with the addre
ss 2099.
2003 LXI H ,42F2H Loads data in the HL register pair.
2006 PUSH H The content of the HL register pair pushed int
o stack.
2007 DELAY COUNTER
200F
2010 POP H Saved data in stack pointer register to HL regi
ster pair.
www.themeart.com 5
6. PUSH H
The stack pointer is decremented by one to 2098 H
, and the contents of the h register are copied to
memory location 2098H. 8085 Register
F
A
The stack pointer register is again B C
E
D
decremented by one to 2097H,and H 42 F2 L
SP 2097
the contents of the L register are Memory
copied to memory location 2097H.
The contents of the register pair F2 2097
42 2098
HL are not destroyed ; however X 2099
HL is made available for delay
counter. Contents on the stack &in the register
after the PUSH instruction
www.themeart.com 6
7. POP H
The contents of the top of the stack location shown by
the stack pointer are copied in the L register and the
stack pointer register is incremented by one to 2098
H. 8085 Register
The contents of the top of the stack A B
F
C
(now it is 2098H) are copied in the D E
H 42 F2 L
H register,and the stack pointer is SP 2099
incremented by one. MEMORY
The contents of memory location
F2 2097
2097H and 2098 are not destroyed 42 2098
until some other data bytes are X 2099
stored in these location. Contentsafterthe stack and in the registers
on
the POP instruction
www.themeart.com 7
8. Operation of the stack
During pushing, the stack operates in a “decrement
then store” style.
The stack pointer is decremented first, then the
information is placed on the stack.
During poping, the stack operates in a “use then
increment” style.
The information is retrieved from the top of the
stack and then the pointer is incremented.
The SP pointer always points to “the top of the
stack’’.

9. PUSH PSW Register Pair
PUSH PSW (1 Byte Instruction) A Flag
Decrement SP
Copy the contents of
12 80
register A to the memory
location pointed to by SP

10. Pop PSW Register Pair
POP PSW (1 Byte Instruction) A FLAG
Copy the contents of the 12 80
memory location pointed to
by the SP to Flag register
Increment SP
Copy the contents of the
FFFB
memory location pointed to FFFC
by the SP to register A FFFD 80
FFFE 12
Increment SP FFFF

11. Subroutines
A subroutine is group of instruction written sepa
rately from the main program to perform a func
tion that occurs repeatedly in the main program
.
When a main program calls a subroutine the pro
gram execution is transferred to the subroutine
after the completion of the subroutine ,the prog
ram execution returns to the main program.
The microprocessor uses the stack to store the r
eturn address of the subroutine.
www.themeart.com 11
12. Subroutines
The 8085 has two instructions for dealing
with subroutines.
– The CALL instruction is used to redirect
program execution to the subroutine.
– The RET instruction is used to return to t
he main program at the end of the subro
utine .
www.themeart.com 12
13. The CALL instruction
CALL ,16 bit
Call subroutine in conditionally located at
the memory address specified by the 16
bit operand.
This instruction places the address of the
next instruction on the stack and transfer
the program execution to the subroutine
address.
www.themeart.com 13
14. The RET instruction
Return unconditionally from the subrouti
ne.
This instruction locates the return addre
ss on the top of the stack and transfers t
he program execution back to the calling
program.
www.themeart.com 14
15. General characteristics of CALL
& RTE instruction
1. The CALL instructions are 3-byte instruc
tion; the second byte specifies the low
order byte ,and the third byte specifies
the high order byte of the subroutine
address.
2. The return instruction are 1-byte instruc
tions.
3. A CALL instruction must be used in
conjunction with a return instruction in
the subroutine .
www.themeart.com 15
16. Necessary steps to implement
a subroutine
The stack pointer register must be initiali
zed ,preferably at the highest memory lo
cation of the R/W memory.
The call instruction should be used in the
main program accompanied by the RET i
nstruction in the subroutine.
www.themeart.com 16
17. Conditional CALL and RTE Instructions
The 8085 supports conditional CALL and co
nditional RTE instructions.
– The same conditions used with conditional
JUMP instructions can be used.
– CC, call subroutine if Carry flag is set.
– CNC, call subroutine if Carry flag is not set
– RC, return from subroutine if Carry flag is
set
– RNC, return from subroutine if Carry flag
is not set.
