Three SQL Keywords in QuestDB for Finding Missing Data

Aggregated on: 2023-01-29 15:59:29

Whether you are just starting to work with a specific data set or monitoring activities and reports based on existing data sets, one of the first things you need to consider is the quality of the data you’re dealing with. Continuity is one of the most critical factors in gauging the quality of time-series data. Time-series systems usually serve use cases where data needs to be consumed, processed, and acted upon with urgency. Take the example of a public transport vehicle. For the safety of passengers and the timeliness of the service, vehicles need their various sensors — GPS, proximity sensors, pressure sensors, engine diagnostics sensors, and so on. Continuously using the data from these sensors helps the public transport service guarantee timeliness, safety, and reliability. However, a break in the data coming from these sensors would mean that there’s a problem.

3 Examples of Address Autofill Forms to Collect Shipping and Payment Addresses

Aggregated on: 2023-01-29 15:59:29

Businesses often use forms to collect information about their customers. The most important information is often the address. Companies that ship goods or brochures to users obviously need an accurate shipping address. There are many other businesses (like banks) that also require users to provide their addresses for regulatory purposes and other various reasons. The Difficulty of Collecting Verified User Addresses We’ve established that addresses are necessary and sometimes an essential part of a business model. Despite their importance, many businesses have difficulty collecting and verifying addresses.Collecting a verified address can be difficult for multiple reasons. For example, there may be new addresses that aren’t yet added to geolocation databases. Also, there may be multiple streets or cities with the same.Webmasters often use a custom field that matches the user’s input with verified addresses. This is one way to verify a user's address. The problem is that these input fields are not flexible. New addresses are sometimes not added to the database, so users can’t select them.

How to Use AppSheet: A Guide to Data Tab Sections

Aggregated on: 2023-01-29 15:29:29

The first part of my Google AppSheet tutorial offered a basic understanding of how to create a new app based on a data table using the Google AppSheet platform. You should know how data sources work, and be aware of the rules you need to follow to make the whole development process smooth. But it's easy to see that when it comes to functionality and visuals, the application created in step one still has a long way to go. In this article, I'll show you how to make it even more functional. I’ll start with some basic theories. I’ll introduce you to the Data tab, and explain what you can do with the various sections you’ll find inside. Later on, I’ll show you how to put that knowledge to good use – I’ll present three examples of specific changes that can be made to your sample app to improve it in several areas. In short, you’ll learn how to use AppSheet to better effect.

Taming Cloud Costs With Infracost

Aggregated on: 2023-01-28 16:14:28

When we combine the cloud with IaC tools like Terraform and continuous deployment we get the almost magical ability to create resources on demand. For all its benefits, however, the cloud has also introduced a set of difficulties, one of which is estimating cloud costs accurately. Cloud providers have complex cost structures that are constantly changing. AWS, for example, offers 536 types of EC2 Linux machines. Many of them have similar names and features. Take for example "m6g.2xlarge" and "m6gd.2xlarge" — the only difference is that the second comes with an SSD drive, which will add $60 dollars to the bill. Often, making a mistake in defining your infrastructure can cause your bill to balloon at the end of the month.

A Simple Union Between .NET Core and Python

Aggregated on: 2023-01-28 15:44:28

Python is a powerful and versatile programming language that has become increasingly popular. For many, it’s one of the very first programming languages they pick up when getting started. Some of the highest traffic posts on my blog many years after they were written look at using C# and Python together. Today we’re going to explore how you can use Python from inside a C# .NET Core application with much more modern approaches than my original articles. Enter Pythonnet! Pythonnet Package and Getting Started We’re going to be looking at Python for .NET in order to accomplish this goal. This library allows you to take advantage of Python installed on the running machine from within your .NET Core applications. You must configure it to point at the corresponding Python DLL that you’d like to use, and after a couple of lines of initialization you’re off to the races!

Aggregated on: 2023-01-27 20:59:28

Nullable reference types appeared in C# three years ago. By this time, they found their audience. But even those who work with this “beast” may not know all its capabilities. Let’s figure out how to work with these types more efficiently. Introduction Nullable reference types are designed to help create a better and safer application architecture. At the code writing stage, it is necessary to understand whether this or that reference variable can be null or not, whether the method can return null, and so on.

Real-Time Stream Processing With Hazelcast and StreamNative

Aggregated on: 2023-01-27 17:44:28

One of the most useful features of real-time stream processing is to combine the strengths and advantages of various technologies to provide a unique developer experience and an efficient way of processing data in real-time at scale. Hazelcast is a real-time distributed computation and storage platform for consistently low latency queries, aggregation, and stateful computation against real-time event streams and traditional data sources. Apache Pulsar is a real-time multitenant geo-replicated distributed pub-sub messaging and streaming platform for real-time workloads, handling millions of events per hour. However, real-time stream processing is not an easy task, especially when combining multiple live streams with large volumes of data stored in external data storages to provide context and instant results. When it comes to usage, Hazelcast can be used for the following things:

Cloud Native London Meetup: 3 Pitfalls Everyone Should Avoid With Cloud Data

Aggregated on: 2023-01-27 15:14:28

The Quest for REST

Aggregated on: 2023-01-26 20:29:27

Since I started working for Apache APISIX, I have tried to deepen my understanding of REST via various means. Did you read my review of the "API Design Patterns" book? In the current literature, REST is generally promoted as the best thing since sliced bread. Yet, it comes with lots of challenges. In 2010(!), Martin Fowler wrote a post on the glory of REST. He lists three steps for an API to become truly REST:

Playwright vs. Cypress: The King Is Dead, Long Live the King?

Aggregated on: 2023-01-26 19:59:27

QA automation tools are an essential part of the software development process because they enable developers to test the functionality and performance of their apps before making them available to the public. There are many different QA automation tools available, among them Cypress and Playwright. The latter has been gaining a lot of popularity, so today, I would like to compare these helpful tools. When Cypress hit the market, it broke the rules that Selenium had been following for a long time. As a result, Cypress has a different architecture for working; it uses the Chrome Dev Protocol, doesn’t really use the JSON Wire Protocol (like Selenium), and also has a lot of flexibility. So far, Playwright seems to be coming up with the same idea to make life easier from the testing side for QA engineers and developers.

Why It Is Important To Have an Ownership as a DevOps Engineer

Aggregated on: 2023-01-26 19:59:27

As a DevOps engineer, one of the most important aspects of your job is to have a sense of ownership over the software development and delivery process. This means taking responsibility for the entire process, from design and development to deployment and maintenance. It also means proactively identifying and resolving issues and continuously looking for ways to improve the process. Understanding of the Software Delivery Process Having ownership as a DevOps engineer is essential for several reasons. First, it allows you better to understand the entire software development and delivery process. When you take ownership, you are more likely to be aware of potential issues and be able to anticipate and proactively address them. This results in fewer delays and disruptions and a more efficient and reliable delivery process. By understanding the process from start to finish, you can identify bottlenecks and optimize them, resulting in faster delivery and better software quality.

Artificial Intelligence in Drug Discovery

Aggregated on: 2023-01-26 19:29:27

Much of the existing hype in biotech has concentrated around the promise of revolutionising drug discovery. After all, the last decade was a so-called golden age in the field. From 2012 to 2021, compared to the prior decade, an increase of 73% new medicines were approved — 25% more than the one before that. These medicines include immunotherapies for cancer, gene therapies, and, of course, Covid vaccines. On the face of it, the pharmaceutical industry is doing well. But there are increasingly worrying trends. Drug discovery is becoming prohibitively expensive and risky. As of today, it costs between $1bn-$3bn on average and 12–18 years to bring a new drug to market. Meanwhile, the average price of a new medicine has skyrocketed from $2k in 2007 to $180k in 2021.

The Top 3 Challenges Facing Engineering Leaders Today—And How to Overcome Them

Aggregated on: 2023-01-26 17:14:27

It's no secret that a tech startup is only as good as its engineering team. It's tempting to follow that statement by saying an engineering team is only as good as its talent. That's true, to some extent, but it takes expertise and leadership to get the most out of your talent—and, of course, to identify and recruit the right employees in the first place. To use the most obvious analogy, even an all-star soccer team is unlikely to win a championship without a savvy coach at the helm. Similarly, even the most stacked engineering team (pardon the pun) risks falling short without a smart and persistent leader. As the engineering lead at a growing up startup, I've experienced success and navigated numerous challenges. While a leader's role is multifaceted, steering the ship through difficult times is one of the most critical aspects. So let's take a look at the three biggest challenges I've encountered and how they can be overcome.

What Is Policy-as-Code? An Introduction to Open Policy Agent

Aggregated on: 2023-01-26 13:29:27

In the cloud-native era, we often hear that "security is job zero," which means it's even more important than any number one priority. Modern infrastructure and methodologies bring us enormous benefits, but, at the same time, since there are more moving parts, there are more things to worry about: how to control access to your infrastructure? How to control access between services? Who can access what? Etc. There are many questions to be answered, including policies: a bunch of security rules, criteria, and conditions. Examples:

Data Mesh vs. Data Fabric: A Tale of Two New Data Paradigms

Aggregated on: 2023-01-26 12:59:27

Data is one of the most critical components of any business, as it allows us to personalize and customize our products for potential consumers. Yet, as important as data is, studies have shown that about 50‑70% of data collected by organizations goes unused and becomes what Gartner calls Dark Data. We can attribute this large amount of unused data to the inefficiencies in the systems that manage them. This post discusses how methods like Data Meshes and Data Fabrics, which have emerged in the past decade, can help mitigate the problems associated with data management.

Do Not Forget About Testing!

Aggregated on: 2023-01-26 01:44:27

Software testing is an important process involved in software development; it is part of the software quality management processes. Testing aims to verify and validate the software. Software verification makes it possible to check that the software produced complies with the specifications. Why Is Testing Needed? Shifts work from developers to testers. Accelerates the software development process. Ensures high software quality by eliminating errors. Provides an external look at the application. Testing checks the quality of the software and products that we produce. The automated tester, for example, is designed to reduce the burden resting on the shoulders of developers. In some companies, the testing department is completely ignored, and, in such circumstances, it is only the developers who create the tests. In this case, when developers maintain the tests, it can be very time-consuming because they also have to maintain the code or documentation.

Key Considerations When Implementing Virtual Kubernetes Clusters

Aggregated on: 2023-01-25 19:44:27

In a Kubernetes context, multi-tenancy refers to sharing one large cluster among multiple teams, applications, or users primarily in lower environments such as development and testing—mainly to reduce cost and operational overhead around managing many clusters. Multi-tenancy is becoming an essential requirement for platform teams deploying Kubernetes infrastructure. Achieving Multi-Tenancy Using Kubernetes Namespaces By far, the most popular approach to achieve multi-tenancy is by using Kubernetes namespaces. Kubernetes namespaces provide an easy way to divide a set of resources, such as pods, services, and deployments, which are only accessible within that namespace.

Facebook (now Meta), Microsoft, Apple, Decentraland, Epic Games, Roblox Corporation, Snapchat, NVIDIA, etc., have announced several projects around this intriguing concept. This has certainly led to discussions on core metaverse features that need to be included in metaverse platforms.

An Implementation of Change Data Capture

Aggregated on: 2023-01-25 17:44:27

Introduction Most enterprise applications generally have relational databases as their persistent data store. Operations on these applications lead to the creation, updating, and deletion of data from tables within relational databases. Downstream applications look at change logs to find out the changes happening in the source systems. The incremental data is essential in processing very specific changes to business data, thereby avoiding the full processing of entire data within operational databases. A new era of applications provides subscription-based services for publishing the changes of the relevant business data. Initial data loads must be performed prior to sending the captured changes from source systems. However, on some legacy application databases, replication tools cannot be used without needing substantial changes to legacy applications. Downstream systems are then forced to load entire content from the operational database to process and generate incremental meaningful information as part of overnight batch jobs. This approach increases overall batch execution time and increases strain on infrastructure due to additional load processed on a period (daily/weekly/monthly) basis.

Spring Cloud: How To Deal With Microservice Configuration (Part 1)

Aggregated on: 2023-01-24 21:44:26

Configuring a software system in a monolithic approach does not pose particular problems. To make the configuration properties available to the system, we can store them in a file inside an application folder, in some place in the filesystem, or as OS environment variables. Microservice configuration is a more complex subject. We have to deal with a number, which can be huge, of totally independent services, each with its own configuration. We could even face a scenario in which several instances of the same service need different configuration values. In such a situation, a way to centralize and simplify configuration management would be of great importance. Spring Cloud has its own module to solve these problems, named Spring Cloud Config. This module provides an implementation of a server that exposes an API to retrieve the configuration information, usually stored in some remote repository like Git, and, at the same time, it gives us the means to implement the client side meant to consume the services of that API.

How Has LINQ Performance Enhanced in .NET 7?

Aggregated on: 2023-01-24 19:29:26

The new version of .NET enhanced the performance of the Min, Max, Average, and Sum methods for arrays and lists. How much do you think their execution speed has increased? Two times or five times? No, they got even faster. Let's see how that was achieved. How Has LINQ Enhanced? LINQ (Language-Integrated Query) is a simple and convenient query language. It allows you to express complex operations in a simple way. Almost every .NET developer uses LINQ. However, this simplicity of use comes at the price of execution speed and extra memory allocation. In most situations, it has no significant effect. However, in cases when performance is critical, these limitations may be pretty unpleasant.

How Observability Is Redefining Developer Roles

Aggregated on: 2023-01-24 19:29:26

Companies use software to run their business in today’s digital world. With the increased use of microservices, containers, and cloud-based technologies, traditional methods of monitoring and solving problems are no longer enough. That’s where observability comes in.
