Software design is the first of three technical activities—design, code generation, and test—that are required to build and verify the software
The design task produces a data design, an architectural design, an interface design, and a component design
The data design transforms the information domain model created during analysis into the data structures that will be required to implement the software

C# Async on iOS and Android - Miguel de Icaza, CTO of XamarinXamarin
Fast, fluid, instant-gratification apps are a must for mobile and C# async makes this much easier to accomplish.
Slides are from the Xamarin CTO and cofounder Miguel de Icaza to understand how and why you should use async for your mobile apps.
This is supposed to be an introductory presentation on Agile.
In this presentation I give some examples of heavy weight methods and their implications on your project. Then I give a quick overview of Agile methods, the rationale behind it, its origin, its values and principles. I move on to describe that what I see happening today in the industry is really waterfall in the name of Agile. I give some reasons why this is happening and then I give some pointers to move away from this flawed thinking.
Bottom line, Agile is not a Silver Bullet and don't fall pray to marketing gimmicks. Question dogmatic claims. Adapt Agile to your needs and take baby steps.
Silver Bullet: The 5 P's to unlock your digital agenda including the one most...Aman Narain
The Silver Bullet is a presentation that introduces the forces that are driving the greatest amount of change across industry since the industrial revolution. In this presentation Aman explains his framework of the 5P's: Purpose, Process, Productivity, Platform and People, and how leadership team need to change their approaches to these to fight commoditization and redundancy. The final P: People (& Culture) is in Aman's opinion and experience the "Silver Bullet" - the one thing that lies at the bedrock or in his words is the soil from which this change germinates.

Deep Dive into the Idea of Software ArchitectureMatthew Clarke
This talk was an experiment in combining a number of ideas I'd been learning and thinking about into a coherent presentation, that would hopefully be useful. The was to give a solid grounding to the idea of software architecture, including taking a critical look at what it is and if it really matters. It then moves into the topics of boundaries and abstractions, horizontal and vertical layers, cross-cutting concerns, "Clean Architecture" and the Dependency Rule it rests upon. It was presented internally at Genesis Energy in September 2018.
Kelis King offer involve conducting system testing to ensure correct operation, and integration testing to ensure the system integrates correctly with other required systems, such as databases.
This presentation explores the reasons why software projects are significantly more difficult to manage than other types of projects. Software-specific issues related to scope, resources, and time are explored, as well as how software projects differ from other projects in the physical world. An argument for why software constitutes a “Wicked Problem” is expanded, and numerous software development myths are attacked with real-world anecdotes and solutions.
Some of the most famous information breaches over the past few years have been a result of entry through embedded and IoT system environments. Often these breaches are a result of unexpected system architecture and service connectivity on the network that allows the hacker to enter through an embedded device and make their way to the financial or corporate servers. Experts in embedded security discuss key security issues for embedded systems and how to address them.
Using Defensive Pessimism to Build Great Software at YMLAdam_Talcott
From The Silicon Valley iOS Developers' Meetup held at YML in Redwood City, CA on June 11, 2018.
Using “Defensive Pessimism” to Build Great Software at YML
Adam Talcott, Edward Cessna, and Ramsundar Shandilya, Y Media Labs
At YML, we take pride in creating great software as part of our mission to make digital products and experiences which have lasting impact. An important part of our process is anticipating the various scenarios our software may face and taking those scenarios into account from design through deployment and beyond. At YML, we refer to this concept as “defensive pessimism”.
After introducing YML, a customer experience design and technology agency with a vision of becoming our clients’ most valued partner, we will dive into defensive pessimism. We will discuss the ramifications for design and review examples of user experiences created with defensive pessimism in mind. We will also cover the resulting architecture considerations and the impact on reliability.

Launch Your Streaming Platforms in MinutesRoshan Dwivedi
The claim of launching a streaming platform in minutes might be a bit of an exaggeration, but there are services that can significantly streamline the process. Here's a breakdown:
Pros of Speedy Streaming Platform Launch Services:
No coding required: These services often use drag-and-drop interfaces or pre-built templates, eliminating the need for programming knowledge.
Faster setup: Compared to building from scratch, these platforms can get you up and running much quicker.
All-in-one solutions: Many services offer features like content management systems (CMS), video players, and monetization tools, reducing the need for multiple integrations.
Things to Consider:
Limited customization: These platforms may offer less flexibility in design and functionality compared to custom-built solutions.
Scalability: As your audience grows, you might need to upgrade to a more robust platform or encounter limitations with the "quick launch" option.
Features: Carefully evaluate which features are included and if they meet your specific needs (e.g., live streaming, subscription options).
Examples of Services for Launching Streaming Platforms:
Muvi [muvi com]
Uscreen [usencreen tv]
Alternatives to Consider:
Existing Streaming platforms: Platforms like YouTube or Twitch might be suitable for basic streaming needs, though monetization options might be limited.
Custom Development: While more time-consuming, custom development offers the most control and flexibility for your platform.
Overall, launching a streaming platform in minutes might not be entirely realistic, but these services can significantly speed up the process compared to building from scratch. Carefully consider your needs and budget when choosing the best option for you.

2. “I believe the hard part of building
software is the specification, design,
and testing of this conceptual
construct, not the labor or
representing it.”
3. NO SILVER BULLET
• Of all the monsters that fill the nightmares of our folklore, none terrify more
than werewolves, because they transform unexpectedly from the familiar into
horrors.
• Why a silver bullet?
• Silver is identified with the moon-A silver bullet offers the fastest, most
powerful, and safest way to slay the fast, powerful, and incredibly
dangerous werewolf
• Same fashion of familiar software project , at least as seen by the non-
technical manage.
4. NO SILVER BULLET (Cont..)
• Usually innocent and straightforward but is capable of becoming a
monster of
• Missed schedules
• Blown budge
• Flawed products
• We have no silver bullet that make software costs drop as rapidly as
computer hardware costs do.
5. NO SILVER BULLET (Cont..)
• Over decades, we see no silver bullet-no single development, that make
improvement in
• Productivity,
• Reliability and
• Simplicity
6. Essence and Accident in
Software Engineering
• All software construction involves Essential and accidental difficulties
• Software, at its core, has these essential difficulties:
• Complexity,
• Conformity,
• Changeability,
• Invisibility
7. Complexity
• Software is complex, even when done right.
• Combinatorial many states, syntax must be just so or else.
• Rich structure, interesting dependencies add to complexity.
• Accidental (as practiced) issues add to complexity.
• Efficient code is usually complicated code.
• Complex code is harder to evolve, results in design drift and even
more complexity.
8. Complexity(Cont..)
• Many problems of developing software products derive from this essential
complexity, due to complexity:
• Difficulty of communication among team members-results into product flaws, cost
overruns, and schedule delays
• Difficulty of enumerating, much less understanding unreliability
• Difficulty of invoking function- makes programs hard to use.
• Complexity of structure brings the difficulty of extending programs to new functions
without creating side effects
9. Conformity
• Software has to be made to agree to common interfaces,
protocols, standards, etc.
• Mostly standards for mastering complexity is arbitrary. Human
institutions and systems must conform these standards and interfaces
and they differ from
• Interface to interface, and from
• Time to time because
• They were designed by different people
10. Changeability
• To be successful is to be changed!
• Try to expect future unforeseen uses.
• Buildings can get changed- but the high costs of change
• Software product is found to be useful
• People try it in new cases at the edge of or beyond the original domain.
• The pressures for extended function come chiefly from users who like
the basic function and invent new uses for it.
11. Changeability(Cont..)
• In short, the software product is embedded in a cultural matrix of :
• Applications, users, laws, and machine vehicles.
• These all change continually, and their changes inexorably force
change upon the software product.
• In order to keep system flexible and marketable, Software is constantly
subject to pressures for change un like buildings, cars or computers
manufactured things are infrequently changed after manufacture.
• Essential changes incorporate in models, serial-no. copies of the same
basic design.
12. Changeability(Cont..)
• We change software because !
• It is easy to update existing systems in the field (in theory)
• We can undo changes if desired (in theory)
13. Invisibility
• Software is invisible and unvisualizable
• The floor plan of a building helps both architect and client evaluate
spaces, traffic flows, views. contradictions and omissions become
obvious.
• No geometrical representation like map of land, diagram of chips
• Although we can use various diagrams to help us visualize aspects of
software (control flow, data dependencies, OMT/UML)
• But that's NOT quite the same thing as, say, the blueprints of a
building.
14. Invisibility(Cont..)
• Still Unvisualizable ! Because..
• Even a progress in restricting and simplifying the structures of
software, they remain inherently unvisualizable, and thus do not
permit the mind to use some of its most powerful conceptual tools.
15. What about these Silver Bullets???
• HLLs
• Frees us from byte-level thinking (accidental complexity).
• IDE
• AI
-Certainly, AI techniques are useful in many application domains, but not
as a silver bullet to solve the SE prob.
• Graphical programming e.g UML, SDL, OOD
16. Promising attacks on conceptual essence
• Buy, don't build
• Requirements are the essence of a software system.
• Focusing on getting the requirements right is a direct attack on essential
problems.
• Rapid Prototyping:
• Take requirements, build mock up, show to user, analyze feedback, repeat.
• Early feedback means less chance for requirements errors (which are the
most expensive), fast turnaround in problem space to narrow
misunderstandings and educate customer.
17. Promising attacks on conceptual
essence(Cont..)
• Staged Delivery incremental development……
• Get a skeleton system up and running, flesh it out as you go.
• Helps to get developers feeling like system is real.
• They add their updates as they finish them.
• Microsoft (and many others) uses this approach; works well for them.
• Skillful Designers
• Find good people and keep them.
• Pay them well, encourage them.
• Above all, listen to them.
18. Promising attacks on conceptual
essence(Cont..)
• Skillful Designers
• However, “great software design” is mostly “pure” design (not
engineering); it’s an act of creativity and innovation balanced against
experience and good engineering.
• It’s impossible to teach.
20. Good news!
We have made great headway in solving the accidental
problems!
Orders of magnitude improvements!
Bad news!
Progress on essential problems will be much slower going.
