What Is The Definition of Done In Scrum

In today, I would like to discuss one of the most important aspects of Scrum. However, this aspect is often times neglected by organizations implementing Scrum. And that most important aspect is the Definition of "Done". Neglecting the Definition of "Done" is one of the reasons why we see a lot of failed scrum implementations in the market. Not putting enough emphasis on technical excellence in the Definition of "Done" is one of the reasons why we see a lot of products with technical debt in the market. If I can summarize scrum into a single line statement, it would be to continuously deliver a done increment that achieve the Sprint Goal every single Sprint. So because of these problems we found in the industry, in today's video I'm going to talk about the Definition of "Done" and the importance of "Done" in Scrum. Many of my future videos is going to refer back to today's video, so make sure you don't go anywhere to stay on this video. A lot of people think that the Definition of "Done" is the same as Acceptance Criteria.

Who Should Be Your Scrum Product Owner

Today I'm gonna talk about Who should be your Product Owner? Alright let's do this! Before we talk about who should be your Product Owner, let's talk about some of the misconceptions we often see in the market regarding the Product Owner role. There is a common misconception in the market that the Product Owner is just another name for a business analyst who writes the user stories for the development team. A lot of companies think that the Product Owner is a tactical role and only play at the Scrum team level. So that's why a lot of companies assigns the Product Owner role to the business analysts.

What is Apache Kafka

I'd like to tell you what Apache Kafka is, but first, I wanna start with some background. For a long time now, we have written programs that store information in databases. Now, what databases encourage us to do is to think of the world in terms of things, things like, I don't know, users and maybe a thermostat. That's a thermometer, but you get the idea. Maybe a physical thing, like a train, let's see, here's a train. Things, there are things in the world. Database encourages us to think in those terms and those things have some state. We take that state, we store it in the database. This has worked well for decades, but now some people are finding that it's better, rather than thinking of things first, to think of events first. Now events have some state too, right? An event has a description of what happened with it, but the primary idea is that the event is an indication in time that the thing took place.

Architecht Interview Questions And Answers

The first question during your architect interview is going to be: Tell me about yourself and the past experiences you have relevant to the role of an architect? So, here is my suggested answer. “I am someone who is very passionate about my work as an Architect. I am highly-professional, creative, flexible and, above all, I hold the relevant technical knowledge and expertise to carry out this job in line with the expectations of your company. The past experiences I have relevant to this role include, previous stints as an Architect at both small and medium-sized organizations, whereby I was often working with a diverse range of clients on complex architectural projects that involved large numbers of interested stakeholders and contractors. I have never missed a project deadline and I am always able to come up with solutions to often complex financial or infrastructural architectural issues that meet the needs of the client. One of the main strengths I possess as an Architect, that I feel makes me a strong contender for this position, is the fact I am someone who always takes ownership of challenging situations and I will go the extra mile to come up with the right solution to the project I am responsible for.”

System Design Interview Distributed Cache

Today we design a distributed cache. We will start with some simple ideas and little by little evolve our design into a fully-fledged architecture. Approach, that we highly encourage you to use during a real interview. We also will discuss several important tips along the way. As usual, let's start with the problem statement. Let’s take a look at a typical setup, a web application backed by a data store. This data store may be a database or another web service. Client makes a call to the web application, which in turn makes a call to the data store and result is returned back to the client. There may be several issues with this setup. First, calls to the data store may take a long time to execute or may utilize a lot of system resources

System Design Interview Notification Service

Welcome to the system design interview channel. Today we design a notification service. Let's start with the problem statement. In the world of web services there are many scenarios when messages need to be sent in a reaction to some event. For example, when credit card transaction amount exceeded a limit and card holder needs to be notified. Or service monitoring system encountered a large number of faults produced by API and on-call engineer needs to be notified. In more general terms, let's say there is a component called Publisher which produces messages that need to be delivered to a group of other components, called Subscribers. We could have setup a synchronous communication between Publisher and Subscribers, when Publisher calls each Subscriber in some order and waits for the response. But this introduces many different challenges: hard to scale such system when number of subscribers and messages grow and hard to extend such solution to support different types of subscribers.

System Design Interview Distributed Message Queue

Today we design a distributed message queue. First, let’s make sure we are on the same page regarding the problem statement. What is a distributed message queue? Let's say there are two web-services called producer and consumer, and they need to communicate with each other. One option is to setup a synchronous communication, when producer makes a call to a consumer and waits for a response. This approach has its own pros and cons. Synchronous communication is easier and faster to implement. At the same time synchronous communication makes it harder to deal with consumer service failures. We need to think when and how to properly retry failed requests, how not to overwhelm consumer service with too many requests and how to deal with a slow consumer service host. Another option is to introduce a new component that helps to setup asynchronous communication. Producer sends data to that component and exactly one consumer gets this data a short time after. Such component is called a queue. And it is distributed, because data is stored across several machines. Please do not confuse queue with a topic

Prepare for Your Google Interview Systems Design

Today, we will cover communication, designing with scale in mind, concrete and quantitative solutions, how you manage trade-offs and compromises and overall best practices. But before we jump into the core focus areas of this interview, here are a few things to note: You will not be coding in this interview. There will also be significant time constraints. We’ll expect you to gather requirements and to develop an initial solution in the first 20 minutes. So please be sure to use your time wisely. Communication is incredibly important in the work we do at Google. And that’s because it’s key to how we approach developing and building our products. In your interview, it’s important to demonstrate those qualities

How Much Does It Cost To Build An Application in 2020

So, how much does it really cost to make an app? I think that question has been asked like five gazillion times, right?

And hey if you're just meeting my name is Arsh Singh. I'm a growth strategist for entrepreneurs And I help you launch and scale your business using mobile apps

Motivations and Customer Use Cases, Apache Kafka

Let's look at some of the motivations people have for using a system like Apache Kafka, and what are some use cases? What are people in different industries doing with it? (upbeat music) Now, if you're watching this course, you're probably aware that there is a paradigm shift under way in favor of event-driven architectures. The basic idea here is that the way we've been building systems has been focused on state, on the current state of things, and really a focus When we design systems, we focus on data as things. There's very much a paradigm shift underway from that to a perspective of data as events. There are things that happen in the world, and our primary purpose is to process those events. This relates to a lot of different other architectural trends that are happening at the time, but it's a very real thing. And you can see by way of analogy, something like a newspaper, which is a static snapshot of the state of the world as of press time versus like a news feed, all the news tweets if you follow news accounts on Twitter, all those news tweets that might be happening in your timeline. Those tweets are more like events, little discreet descriptions of things that have happened rather than that summary that you'll see in a broadsheet newspaper, which is going to cause us to want a new kind of data infrastructure.

What Happen To Older Programmers/Developers/Software Engineers

I got a question about programming until old. This question is from Apaven I think. He says, “Last weekend I have discussed a software developer job with my friends about software developer is a dead end job or not. Later I tried to look on the internet and found some good arguments from both sides. Here is a sample about programming as a dead end job.” He’s got a quote from a story here, and he says, “Many programmers find that their employability starts to climb at around age 35. Employers dismiss them as either lacking in the technical skills such as the latest programming language fad or not suitable for entry level, in other words, either unqualified or overqualified. That doesn’t leave much, does it? It’s a sick show that most software developers are out of the field by 40. Employers have admitted this in unguarded moments. Craig Barrett a former chief executive officer of Intel Corp famously remarked the half life of an engineer software or hardware is only a few years while Mark Zuckerberg of Facebook has blurted out that young programmers are superior. I’m not satisfied with the results from my searching, so I would like to know your opinion about this issue.”

What Is Technical Debt In Software Development And The Impact To The Business?

In today, I would like to talk about technical debt specifically in software development. This is one of the topics that I'm passionate about. In fact one of the reasons why I'm interested with Scrum is not only because Scrum emphasize heavily on the people aspect in software development but also because Scrum as taught by Ken Schwabe, one of the co-founders of Scrum, emphasize heavily on technical excellence and professionalism in software development. Interestingly if we look around us, there are more and more organizations using Scrum in our industry and at the same time I also see many organizations care less about technical debt in the product they develop. A lot of people from the business, a lot of managers think that Scrum is only about delivering products fast
