This article is a continuation of the authentication methods t- here we will cover two more advanced authentication methods which include One Time Password (OTP) and Two Factor Authentication (2FA). By Daniel Ciocîrlan.

The One Time Password authentication method is defined in the RFC 2289 internet standard which provides a detailed explanation of how OTP is implemented. OTP tokens can either be generated by a software application running on a computer or phone, or they can also be generated using hardware and there is a wide array of devices on the market providing this functionality.

The main sections in the article:

• Introduction
• Requirements
• One Time Password (OTP)
  • HMAC-based One Time Password (HOTP)
  • Time-based One Time Password (TOTP)
• Two Factor Authentication (2FA)
  • Two Factor Authentication (2FA) Implementation in Scala

In this tutorial we learned about One Time Password Authentication, we explored HMAC-based One Time Password (HOTP) and Time-based One Time Password (TOTP) and created a small application where we implemented Two Factor Authentication using the knowledge we learned. 2FA has gained traction in recent years and as displayed, adds another layer of security to your application. Full code is also provided. Good read!

This guide will walk you through some advanced techniques in prompt design and prompt engineering. If you’re new to prompt engineering, we recommend starting with our introduction to prompt engineering guide. By Eric Urban and suhridpalsule.

While the principles of prompt engineering can be generalized across many different model types, certain models expect a specialized prompt structure. For Azure OpenAI GPT models, there are currently two distinct APIs where prompt engineering comes into play: Chat Completion API and Completion API.

In this article you will get information about:

• System message
• Few-shot learning
• Non chat scenarios
• How to start with clear instructions
• Repeat instructions at the end
• Prime the output
• Add clear syntax
• Break the task down
• Use of affordances

One of the most effective ways to provide reliable answers is to give the model data to draw its responses from (grounding data). If your use case relies on up-to-date, reliable information and is not purely a creative scenario, we strongly recommend providing grounding data. Nice one!

Raspberry Pi are often the gateway device for developers first getting into tinkering with an IoT project. These single-board computers are relatively inexpensive, easy to get started with, and compatible with a variety of different sensors. By Andrew Black.

Looking at a Raspberry Pi from this perspective, it seems like an excellent option for a small IoT deployment. Yet there are some clear challenges that emerge when hoping to utilize the device at a larger scale:

• Raspberry Pi requires a basic OS to be installed on each individual device, and loading this OS onto a fleet of thousands of devices can be a tedious task
• It must be acknowledged that the Raspberry Pi is perhaps overpowered for very basic tasks
• Raspberry PI are built with the intention of being “hacked.”. There are some security concerns that make a Raspberry Pi vulnerable
• Complication of connectivity. RPi have ethernet ports for a hardwired connection and support WiFi, but what if the device is positioned in a location where there is no access to either?

Ultimately when it boils down to scalability for an IoT deployment, what you need is the ability to roll out your devices as quickly and securely as possible in a reproducible format. On a small scale of 10 devices or less, it is very feasible that a Raspberry Pi rollout could be an affordable option. However, in a large or enterprise-level rollout, there are enough logistical challenges to make the RPI an impractical option. Interesting read!

IoT continues to be widely talked about, as new features and possibilities are implemented and described in success stories. In 2022 global spending on IoT had surpassed USD 1 trillion which looks impressive without being a final word or even close to it. By Andrzej Wodnicki.

The industries which used IoT the most were healthcare, transportation, energy, manufacturing, and construction.

Source: https://itsg-global.com/everything-you-have-to-know-about-iot-expansion/

The top 5 countries in 2022 when it comes to investing in IoT were US, China, Japan, South Korea, and Germany. The processes that were most commonly benefiting from IoT were tracking, predictive maintenance, condition monitoring, quality control, and supply chain management. Those things make a lot of sense because sensors can be introduced to different stages of those processes which is going to cut costs. Good read!

The goal of your blog is to engage your target audience by encouraging them to read your content. And you can also achieve this if you provide an excellent user experience. By Christopher Jan Benitez.

This post discusses how you can better accommodate your readers by tweaking your blog. Doing so enables you to keep them on your blog longer as they read your content in the hopes of turning them into your followers, if not customers. Further in the article you will find information how to:

• Make the pages load faster
• Observe proper formatting
• Consider removing sidebar
• Reduce options
• Write about what users want to read
• Top 8 UX design blog to inspire you

People visited your site to read your content about the topic they searched for online. They’re not interested in the offers on your pop-ups or ad banners. At the same time, you can’t load up your pages with multiple calls to action that have nothing to do with your content’s topic. And most importantly - choose a niche. What are you passionate about? What do you know a lot about? What do you think people would be interested in reading about? Once you’ve chosen a niche, you can start to focus on creating content that is relevant to that audience. Some good advice here!

Large Scale Scrum, LeSS for short, has caught your attention. Maybe you’ve just started with Scrum but are already thinking about the next steps. Maybe you’re a veteran of single-team Scrum, looking to expand it to other teams. By @nimblework.com.

LeSS keeps Scrum’s core intact: exposing organizational design weaknesses through a minimal framework and letting you solve the complex problems inherent in development, through empirical process control and continuous improvement.

This article covers:

• Brief history
• Principles, and practices
• Rules
• Practices
• Queueing theory
• Key roles and responsibilities
• Organizational structure

In a LeSS organization there’s no place for project managers or a program/ project management office (PMO). You don’t need them because their responsibilities transfer to a Product Owner and the feature teams, and to avoid confusion and potentially even turf wars. In a LeSS organization, Feature Teams do the development work. They are what others would call product teams. Each team creates and is responsible for end-to-end customer-centric features, rather than components or a technical layer.

LeSS seeks to apply the “principles, purpose, elements, and elegance of Scrum in a large-scale context, as simply as possible.” Among other principles and practices, it uses Lean Thinking and Systems thinking to keep the framework and your overhead as light as possible and still guide you in important decisions.

If you subscribe to the idea of “Less Is More” and want to keep overhead to a minimum. If you value keeping everyone focused on the whole product at all times. If you’re comfortable with running experiments and adapting as you go. If you like teams progressing in their Scrum adoption at their own pace. Then you’re ready to adopt Large Scale Scrum as your framework for scaling agile. Your first step toward that would be to learn more about LeSS, especially its core principles and its principles for adopting it. Super interesting read!
