Importing multiple extension assemblies in C# with MEF

Aggregated on: Mon May 22 2023 10:15:37 GMT+0000 (Coordinated Universal Time)

An application rarely depends on one single extension. If it does, then it has something wrong with its extension model and maybe it doesn’t need one after all. An extensible application allows the use of a multiple extensions that satisfy the standard exposed by the SDK: In my previous article I showed how to use MEF to import a single external assembly. However, MEF doesn’t impose a limit on the number of assemblies that can be imported, although some conventions should be followed.

How to Use RxJava with Android: Managing Async API Calls

Aggregated on: Mon May 22 2023 10:15:37 GMT+0000 (Coordinated Universal Time)

We've written about RxJava and Android before, but this tutorial from howrobotswork takes a more in-depth look at RxJava through one particular use case: managing async API calls. If you're not familiar with RxJava, howrobotswork describes it as a "Java implementation of Reactive Extensions developed by Netflix" for asynchronous and event-based programs. The howrobotswork tutorial provides some background and set-up, but mostly focuses on how to build an Android REST API client with RxJava observables. Any Android developers looking to get deeper into RxJava should take a look at the full tutorial. Also, it's the first part in a series, and the second part - error handling with RxJava - has already been posted, potentially with more to come.

How to Use Groovy to Build Android Apps

Aggregated on: Mon May 22 2023 10:15:37 GMT+0000 (Coordinated Universal Time)

One of the key ideas of Groovy is to help Java developers be more productive, so why not bring it to Android? Luckily, Cédric Champeau has done exactly that with this Gradle plug-in on available on GitHub. It looks pretty straight-forward: edit your build.gradle a bit, choose your Groovy version and modules, add a depedency, and that's about it. It does seem to be leaning toward Android Studio, but that's okay, people seem to like Android Studio.

How to Make an Existing App Work with Android Wear

Aggregated on: Mon May 22 2023 05:30:37 GMT+0000 (Coordinated Universal Time)

You've probably heard about Android Wear by now, but it still presents some questions for Android developers not yet fully invested in wearables. For example, how does one transition from mobile Android development to Android Wear? One option that makes a lot of sense is to work with existing Android apps that you've already developed, which Ivan Kocijan suggests in this recent post on Infinum. He provides a four-step walkthrough, in fact, of how an existing app - Erste & Steiermärkische Bank's queuing app - can be easily updated from an Android mobile version to Android Wear. It looks pretty cool:

How They Did It: Cut the Rope in HTML5

Aggregated on: Mon May 22 2023 05:30:37 GMT+0000 (Coordinated Universal Time)

For all its plausible physics, Angry Birds is more stress-relief than puzzle -- less a gravitational/collision brain-teaser, and more a cortisol drain. Wonderful things, these 2D cortisol drains, but not as mentally satisfying as something like Cut the Rope -- another iOS (and Android) game, originally written in Objective-C, and enjoyable in great part because of its perfectly smooth obedience to physical laws.

How JavaScript Timers Work

Aggregated on: Mon May 22 2023 05:30:37 GMT+0000 (Coordinated Universal Time)

At a fundamental level it's important to understand how JavaScript timers work. Oftentimes they behave unintuitively because of the single thread which they are in. Let's start by examining the three functions that we have access to with which to construct and manipulate timers. var id = setTimeout(fn, delay); - Initiates a single timer which will call the specified function after the delay. The function returns a unique ID with which the timer can be canceled at a later time. var id = setInterval(fn, delay); - Similar to setTimeout but continually calls the function (with a delay every time) until it is canceled. clearInterval(id); - Accepts a timer ID (returned by either of the aforementioned functions) and stops the timer callback from occurring. In order to understand how the timers work internally there's one important concept that needs to be explored: timer delay is not guaranteed. Since all JavaScript in a browser executes on a single thread, asynchronous events (such as mouse clicks and timers) are only run when there's been an opening in the execution. This is best demonstrated with a diagram, like in the following:

How to Get a Non-Programmer Started with R

Aggregated on: Mon May 22 2023 05:30:37 GMT+0000 (Coordinated Universal Time)

This recent article from Alyssa Frazee's blog provides a tutorial on how to help non-programmers get started with R. Given that R is a programming language popular outside of the development world - its focus on statistics and data visualization makes it popular among data scientists and sociologists, for example - the tutorial is a useful starting point and provides an outline of the need-to-know aspects of R. A lot of ground is covered in a series of quick and concise steps. For instance: How to download R and RStudio Working with graphics Data types Exploratory data analysis And more. An important detail here, though, is the intended audience of the tutorial: It is not for non-programmers attempting to learn R, but really for programmers attempting to teach R to non-programmers, especially in a concise, crash-course fashion. I think there would definitely be some value here for non-programmers or even programmers who are new to R (though experienced programmers interested in R might be better served elsewhere), because it provides an outline of things you need to research and learn, but I believe the intention is to be more of an informal teaching aid.

According to Philip Rathle on The New Stack, graph databases can be used for more than just finding football stadiums. In fact, they can help with some pretty interesting problems: breaking up organized crime, for example. The example Rathle relies on for this article isn't the Sopranos-style organized crime you might be picturing, but rings of bank and credit card fraudsters. These are perpetrators of "first-party fraud," defined by Rathle as people who "...apply for credit cards, loans, overdrafts, and unsecured banking credit lines with no intention of paying any of them back."

Who says you need one of those new-fangled rapid-prototype languages like Ruby to get things done quickly? Certainly not Trisha Gee, who in this recent talk demonstrates that a language like Java can be used just as efficiently to quickly build a web application - in about an hour of coding live, in fact, because you don't want to be that polished anyways, right? Beyond Java, she describes the other pieces of the puzzle as well - MongoDB, Groovy, AngularJS, and HTML5 - or as she puts it, "... a fully buzz-word-compliant application."

Overfitting, Generalization, and the Bias-Variance Tradeoff

Aggregated on: Sun May 21 2023 21:15:37 GMT+0000 (Coordinated Universal Time)

Machine learning is a complex field, with one of its biggest challenges is building models that can predict outcomes for new data. Building a model that fits the training data perfectly is easy, but the real test is whether it can accurately predict outcomes for new data. This article delves into the concepts of overfitting and generalization and explores how they relate to the bias vs. variance trade-off. We will also discuss techniques for avoiding overfitting and finding the optimal balance between bias and variance in our models.

Aggregated on: Sun May 21 2023 20:30:37 GMT+0000 (Coordinated Universal Time)

Does the following routine sound familiar? In the morning, your voice assistant gives you today's weather forecast. And then, on your way to work, a navigation app gives you real-time traffic updates, and in the evening, a cooking app helps you cook up dinner with audible steps. In such a routine, machine-generated voice plays an integral part, creating an engaging, personalized experience. The technology that powers this is called text-to-speech, or TTS for short. It is a kind of assistive technology reading aloud digital text, which therefore is also known as read-aloud technology.

NestJS + Mongo + Typegoose

Aggregated on: Fri May 19 2023 23:45:36 GMT+0000 (Coordinated Universal Time)

Three Options To Use Mongo With Node (And NestJS) We will look into each and every one of them, and I will provide an example of how you can use MongoDB in your NestJS application in a headache-free way. The best tutorial I have found for NestJS + Mongoose is here. The issue I had with it is that I had to write the schema definitions and the typescript interfaces. If you are fine with writing everything two times, one for the Schema and one for the Document as Typescript Interface, maybe this is the best way to go! NestJS + TypeORM is where you can actually use TypeORM with MongoDB; however, I do not recommend this. If you want to learn more, I would ask you to read this blog post. NestJS + Typegoose — basically, it uses your domain objects to get the schema from them. And this is what this post is all about. There is a lot of documentation on how you can achieve that; however, I didn’t like most of it; it just looked like too much code. On top of that, ALL tutorials ALWAYS include using a DTO class, and I don’t see a reason to use DTO classes at all in 99% of the cases. DTOs are great, don’t get me wrong, there are many pros of using DTOs, but none of the tutorials on the internet actually explains why they want DTOs, and in fact, none of them need DTOs so I would like to write the easiest straightforward way with NestJS + MongoDB + and TypeGoose. So, first of all, we will install NestJS CLI, NestJS is very, very similar to Angular, and even if you don't like Angular, trust me, you will like NestJS since I am actually the same! For a great beginner's tutorial for NestJS, you can read here find.

As automation testers, many times, we reminisce about what is going on behind the scenes after the URL is passed to the web browser. What happens once the browser requests to load a website, or how does it know whether its request has been accepted and is ready to be fulfilled or not. The answer to these is the HTTP response status codes for the resource APIs executed on the backend for the website. The request goes to the website server, which tells the browser through these numeric codes whether it is successful or not.

It can also facilitate the integration system of many renewable energy sources, such as wind and solar power, into the electricity grid by providing real-time data on energy production and consumption. Furthermore, IoT has many prospects to transform the business world by permitting greater optimization, automation, and control.

Having worked with many clients, I have come to the realization that data integration is a critical component of modern businesses that rely on data-driven insights. The number of enterprise applications, multi-cloud hosted applications, SaaS, PaaS, IaaS, and on-premises solutions is vast, and the complexity of integrating data from these data sources can be overwhelming. What To Look For There is no one-size-fits-all solution, but some pointers that have been helpful in my customer conversations include understanding the requirements around data freshness, reporting use cases (current vs. historical), transformations (ELT, ETL), CDC capabilities, and existing investments to maximize the value. With some qualified discovery questions, we can narrow down the options to a few solutions and ultimately launch a pilot-to-production process with the selected solutions to ensure feasibility.

From Kubernetes to Argo to Docker to Terraform, the most influential cloud-native innovations are open source. The high velocity and mass adoption of projects like Kubernetes show that in order to keep pace with innovation, the cloud-native community must come together, share best practices, foster collaboration, and contribute to next-generation technologies. Open-Source and Cloud-Native The Cloud Native Computing Foundation (CNCF), the largest open-source community in the world and the host of international events like KubeCon + CloudNativeCon and CloudNativeSecurityCon, rallies around the idea that open source and democratizing innovation are the best ways to make cloud-native technologies widely available. As a subset of the Linux Foundation, the CNCF brings together thousands of developers and cloud architects around the world to create and maintain hundreds of cloud-native open-source projects.

Change Control Doesn’t Work: When Regulated DevOps Goes Wrong

This week I’ve been reading through the recent judgment from the Swedish FSA on the Swedbank outage. If you’re unfamiliar with this story, Swedbank had a major outage in April 2022 that was caused by an unapproved change to their IT systems. It temporarily left nearly a million customers with incorrect balances, many of whom were unable to meet payments. After investigation, the regulator found that Swedbank had not followed its change management process and issued a SEK850M (~85M USD) fine. That’s a lot of money to you and me but probably didn’t impact their bottom line very much. Either way, I’m sure the whole episode will have been a big wake-up call for the people at the bank whose job it is to ensure adequate risk and change controls. So, what went wrong, and how could it have been avoided?
