The Generic Way To Convert Between Java and PostgreSQL Enums

Aggregated on: 2022-12-27 17:44:10

An enumerated type (enum) is a handy data type that allows us to specify a list of constants to which an object field or database column can be set. The beauty of the enums is that we can enforce data integrity by providing the enum constants in a human-readable format. As a result, it’s unsurprising that this data type is natively supported in Java and PostgreSQL.

I initially needed a CLI tool with auto-completion because I desperately needed it to deal with very long schema and table names. When I first tried it with version 3.4.1, which was the latest at the time, I was seeing many errors. I decided to pause my evaluation and come back later. Luckily, a month later, version 3.5.0 was released which seemed to fix those issues for me. I no longer see Python stack traces. Let's take it for a spin... Pgcli describes itself as a PostgreSQL client with auto-completion and syntax highlighting. Get a pgurl connection string, i.e. postgresql:// or Postgresql environment variables to connect to a cluster.

JSON-Based Serialized LOB Pattern

Aggregated on: 2022-12-27 16:44:10

Serialized LOB (Large Object) pattern is explained in the Patterns of Enterprise Application Architecture book by Martin Fowler. The original paper describes an implementation of the pattern with an example of XML-based serialization. Although nowadays, JSON format is ubiquitous. So, adding a fresh flavor of “JSONization” to the pattern seems fully justifiable. There was mentioned that a binary serialization might win in size and performance, though the main problem with BLOBs (Binary Large Objects) remains the versioning. The changes in classes’ structure may lead to data incompatibility, so it can be problematic to de-serialize your objects from the database. Also, it is hardly achievable to query data inside BLOB. On the other hand, CLOB (Character Large Object) type is human readable, which at least allows for investigating issues. In addition, modern RDBM systems provide instruments to manipulate JSON, like querying and modifying data inside JSON.

Validation With Tagless Final

Aggregated on: 2022-12-27 14:59:10

In one of our previous articles, Validation for Free in Scala, we discussed a validation framework by lifting validators to monad “for free”. In this article, we will discuss a validation framework with Tagless Final. Through examples, we demonstrate how the proposed validation framework can improve the quality of encoding. Validation Validation falls into two categories: Fail Fast and Error Accumulation. In Fail Fast scenario, validators return monadic validation results; a for-comprehension can be used to complete the validation. The following code returns the first error it encounters without executing the rest of the validation:

Some IT projects fail, and mistakes happen. KPMG Project Management survey showed that more than two-thirds of organizations suffered at least one project failure in the previous year. So today, let's focus on less severe cases, which can still be saved! When Do You Need to Look For Help? When completing many software projects and helping various businesses put their ideas to life using code, we've learned that multiple coexisting factors usually cause problems. For example, it was often the case that we took a project over after the previous software development team. Some of these situations were classic project rescue cases where we stepped in to clean up and make things work.

Adopting Kubernetes? Here Are Some Pitfalls You Should Avoid

Aggregated on: 2022-12-26 14:44:09

Knowing your way around a tool is key to putting it to good use, and this concept doesn't just apply to your weekend hobby projects. It's just as true of DevOps essentials like Kubernetes as it is of an artist's favorite brushes or a woodworker's lathe – Cultivating a thorough understanding of your systems enhances the work you produce. ...Or at least it should. Many devs barely have enough time to learn the basics of their preferred toolkits, let alone dive into the intricacies that make them enterprise-worthy. The reality is that mastering Kubernetes is no small task. Although its complexity isn't out of line for such a powerful tool, it tends to work against those trying to find their footing.

Previous Articles I've written about pgbench before, you may find those articles below: Using PGBench with CockroachDB Serverless Optimizing pgbench for CockroachDB Part 1 Motivation I am writing a two-part article on optimizations in pgbench. Pgbench is a common benchmarking utility that comes bundled with PostgreSQL. It's ubiquitous and widely accepted as a standard tool to test database performance. Up until version 15 of pgbench, I was unable to improve performance with CockraochDB and pgbench. With this version, we now have the ability to retry transactions and it improves the performance posture for CockroachDB. However, this is not the only way to address performance issues. Today, I am going to expand on the options available to us and move the performance needle further.

Kubernetes Namespace: How to Use It to Organize and Optimize Costs

Aggregated on: 2022-12-24 17:14:08

When you’re running a relatively small cluster, you might get away with having no structure in place for it. But with time, your cluster will inevitably scale to dozens of pods and hundreds of containers. If you keep running them carefree, you’ll deal with a mess sooner rather than later. Here’s your golden ticket to get out of this chaos: Kubernetes namespace. By keeping your cluster organized with namespaces, labels, and annotations, you’ll avoid the performance, maintenance, and security issues that come together in a package with the lack of control over the deployed objects and services.

Optimizing Pgbench for CockroachDB Part 1

Aggregated on: 2022-12-24 16:29:08

I'm passionate about my job and I document all of my CockroachDB shenanigans. You can find them in my profile. Motivation The previous article left a lot to be desired and I've been meaning to get back to it. Today, we're going to improve on the original article by demonstrating what can be done to improve the performance of pgbench with CockroachDB. Typically, when customers begin their CockroachDB journey, they are faced with a learning curve having no prior knowledge of CockroachDB and many times, the biggest hurdle is isolation. CockroachDB operates in SERIALIZABLE isolation by default, full stop! There are no plans to change the status quo. Instead of weakening isolation, we advise our customers to practice defensible programming and change their application to work around the errors and retries. We're going to treat pgbench like a legacy application and demonstrate the problems and how we can work around them and modernize them for CockroachDB.

It has also made debugging, troubleshooting, and the availability of operational infrastructure much better.

GraphQL in Microservices With Spring and Angular

Aggregated on: 2022-12-24 00:59:08

The AngularAndSpringWithMaps project has been converted from REST endpoints to a GraphQL interface. The project uses Spring GraphQL to provide the backend interface. The Angular frontend uses the Angular HttpClient to post the requests to the backend. GraphQL vs REST From an Architectural Perspective REST Endpoints REST calls retrieve objects with their children. For different root objects, separate REST calls are sent. These calls can accumulate with the number of different root objects that the frontend requests. With relationships between the objects, sequential calls become necessary.

Types of Data: A High Level Explanation for Decision Makers

Aggregated on: 2022-12-23 18:59:08

In this article, I will talk about the different types of data. So, as some of you might be aware, data can be broken down into different types. One such categorization which is very useful when you are building a machine learning pipeline is the following: structured data, semi-structured data, and unstructured data. So What Is the Difference Between These Types of Data? Structured Data This term refers to data that is organized in a tabular format or in something like a relational database which organizes data in multiple tables which can then be joined together. So structured data presents the easiest type of data to work with. If your data is stored in an SQL database, for example, then most data scientists will find it pretty easy to access the database and then extract insights from the data. That being said, not all databases are created equal. Some databases might be organized in a very bad manner; other databases might be organized in a very easy-to-use manner. But all things being equal, structured data is easy to work with.

The Role of Legacy Apps Modernization in Digital Transformation

Aggregated on: 2022-12-23 18:29:08

The routes to digital transformation are countless and each enterprise’s plan is based on its specific strategic priorities. Many organizations take a “rip and replace” approach and choose to start building new systems from the ground up. However, in many instances, this shouldn’t be the case. Completely scrapping legacy technology and starting over could be an unnecessarily long, risky, and costly process. Working on developing a hybrid eco-system where legacy applications are modernized and allowed to co-exist with modern ones in a fully integrated and optimized environment is a more efficient approach to digital transformation. We delve into why this is the case in more detail in this article. Digital Transformation Is a Journey Regardless of geographic location or sector, digital transformation is high on the list of every corporation's top priorities. A common mistake enterprises tend to make, however, is approaching it as a one-off project they need to finish by a set deadline. If they want to succeed in their digital transformation efforts, instead, they need to see it as a process that shouldn’t end. Digital transformation is a journey, not a destination and even when maturity across all dimensions is achieved, enterprises will need to adopt a mindset that involves continuous revisions and rapid response to change.

Python Exception Handling: Try, Except, and Finally in Python

Aggregated on: 2022-12-23 16:44:08

There are two types of error in python, i.e., Exception and Syntax error. Errors are the problems that occur in the program, and the execution of the program will stop due to this error. And on the other hand, if we will talk about exceptions when the normal program is disturbed due to some internal event, then the exception is raised in the program. Difference Between Syntax Error and Exceptions Syntax Error As its name suggests that the error occurred due to the written wrong syntax in the code, which is called a syntax error. And the program will be terminated due to the syntax error.

EDR vs Antivirus: What You Need to Know

Aggregated on: 2022-12-23 16:44:08

A company's endpoints must be effectively protected to be part of its overall cybersecurity plan. While antivirus (AV) and endpoint detection and response (EDR) solutions aim to prevent endpoint security threats, they do it in very different ways. As an advanced alternative to traditional antivirus software, EDR is quickly becoming the new standard. For decades, companies have put their faith in antivirus software as a panacea for enterprise security problems. In contrast, the limitations of "legacy" antivirus have become evident as the sophistication and prevalence of malware threats have expanded over the last decade. Considering these shortcomings of antivirus, some companies have rethought the problems with enterprise security and developed novel approaches to fixing them.

The Javits Center in NYC opened its doors to hundreds of security experts from all around the world on November 15th and 16th, 2022. Over those two info-packed days, attendees participated in panels and presentations and shared their knowledge about enterprise security. Here are just some of the highlights from CyberTech NYC 2022 The Larger the Organization, the More Turtles to Corral Early in the conference, CyberTech Co-Founder Amir Rapaport shared a very good analogy for how large enterprises have transformed, corralling turtles.Turtles move slowly, akin to how fast we adopt new tech or modify existing systems. If you only have a few turtles, keeping up with them and making sure they are safe is pretty straightforward. But when you add more and more turtles, it becomes increasingly difficult to manage them. When you get to hundreds or thousands of turtles, or IT services, manually chasing them and keeping them safe becomes overwhelming.Unfortunately, there is no silver bullet to this problem of herding turtles; it just takes staying vigilant and aware of newly emerging threats. This introductory session set the tone of the event, and his message of staying on top of new trends was echoed throughout the rest of CyberTech.

New Macbook Air Beats M1 Max for Java Development

Aggregated on: 2022-12-22 20:14:07

This is a shocker…I just switched laptops, and I thought I was downgrading from the “top of the line” M1 Max with 64 GB (14.1-inch version) to a “tiny” MacBook Air M2 with “only” 24gb of RAM. Turns out I was wrong. The new M2 seems to be noticeably faster for my use cases as a Java developer. I was at first shocked, but in retrospect, I guess this makes sense. I recently left my job at Lightrun. I usually buy my own laptops, as I don’t enjoy constantly switching devices when I’m at work or working on personal things. But since I worked at Lightrun for so long, I accepted their offer for a laptop. One year after I got the new laptop, I found myself leaving the company. So arguably, this should have been a big mistake. Turns out it wasn’t.

A Complete Guide to Software Testing Life Cycle (STLC)

Aggregated on: 2022-12-22 01:29:07

Software testing is the process of evaluating a software product to detect errors and failures and ensure its suitability for use. It can be performed manually (where testers use their skill, experience, intuition, and knowledge) or automatically (where the tester’s actions are guided by a test script). The fundamental objective of the test process is to ensure that all specified requirements of a software system have been met by the development process and that no undetected errors remain in the system. However, the overall aim of testing is to provide customer or end-user value by detecting defects as early as possible.

Daily Standup Meeting: Ways To Keep It Short and Effective

Aggregated on: 2022-12-21 22:44:06

Developer teams are no strangers to daily standup meetings. Their success in increasing collaboration and visibility has led to their adoption in different types of teams and projects. Every day the whole team has a standup agenda meeting where developers and other team members proactively align with the project and delivery goals, share progress with the team, and be on top of blockers. There are, however, developers who despise standup meetings because they are hyper-vigilant about even the most subtle indicators of unproductivity. They dislike regular standup meetings because they see no advantage to their work. Instead, they think that the daily meeting has little use to their skills and productivity, and they choose to work on projects rather than attend meetings.

Prelude Self-driving cars can change everything in terms of road safety and mobility. Self-driving vehicles are capable of sensing their immediate environment and can move safely with little or no human input. With self-driving cars, real-time alerting systems act as a communication between vehicle and driver. Real-time signaling and alerting have many tangible and intangible benefits. XYZ’s “Autopilot and Full Self-driving capability” has been getting better every year since its introduction. XYZ's patent to “Automate Turn Signals” is an advanced step in enhancing road safety, not only for self-driving cars but also for drivers who ignore or forget to use turn signals. There is always a question, how independent should a vehicle be in making smart decisions? Self-driving cars should be just as intelligent as the driver in making the right decisions.

Using Truffle L2 Boxes to Bridge Blockchain Networks

Aggregated on: 2022-12-21 15:29:06

It’s well known that many blockchains have scalability and congestion problems. These issues have wide-ranging effects from slow transaction times, to increased transaction fees, and degraded user experience. One solution is for web3 to be multi-chain using L2 (layer two) chains. Ethereum L2s, such as Optimism, Arbitrum, and Polygon, build on top of the Ethereum network but are faster and cheaper than Ethereum. As a tradeoff, however, they are often less secure than Ethereum. That’s why L2s handle the day-to-day user activities, while still relying on Ethereum L1 as a behind-the-scenes foundation for a secure and decentralized settlement and data availability layer.

How to Convert HTML to PNG in Java

Aggregated on: 2022-12-21 01:59:06

Since its conception in the late 1980s, HyperText Markup Language (HTML) has persisted as a critical element in displaying web pages online. This ubiquitous programming language continues to offer a detailed framework for structuring the content we see and interact with on the web, allowing us to format text and multimedia components in plain-text code, which is simple enough to change when the need arises. The Transformation of HTML As is the case with nearly all programming languages, HTML has transformed to incorporate dozens of new features over the decades since its introduction, accommodating typical contemporary pressures such as community feedback/critique and the rapid growth of adjacent web development technologies. The results of this transformation are easily visible to us in the output of modern HTML code; for example, the most recent HTML iteration–HTML5, introduced in 2014–offers new, simple elements for embedding video and audio files, as well as much-needed improvements in mobile display and overall mobile functionality.

Aggregated on: 2022-12-20 23:44:06

Regression is a robust statistical measurement for investigating the relationship between one or more independent (input features) variables and one dependent variable (output). In AI, regression is a supervised machine learning algorithm that can predict continuous numeric values. In simpler words, input features from the dataset are fed into the machine learning regression algorithm, which predicts the output values. In this post, we’ll share a machine learning algorithms list of prominent regression techniques and discuss how supervised regression is implemented using the scikit-learn library.

Monitoring QuestDB in Kubernetes As any experienced infrastructure operator will tell you, monitoring and observability tools are critical for supporting production cloud services. Real-time analytics and logs help to detect anomalies and aid in debugging, ultimately improving the ability of a team to recover from (and even prevent) incidents. Since container technologies are drastically changing the infrastructure world, new tools are constantly emerging to help solve these problems. Kubernetes and its ecosystem have addressed the need for infrastructure monitoring with a variety of newly emerging solutions. Thanks to the orchestration benefits that Kubernetes provides, these tools are easy to install, maintain, and use. Luckily, QuestDB is built with these concerns in mind. From the presence of core database features to the support for orchestration tooling, QuestDB is easy to deploy on containerized infrastructure. This tutorial will describe how to use today's most popular open-source tooling to monitor your QuestDB instance running in a Kubernetes cluster.

Aggregated on: 2022-12-20 22:44:06

This article explains how we can configure a custom OAuth 2.0 grant type known as the “mobile” grant type in WSO2 APIM. This mobile grant type is like the password grant type, where a mobile number will be passed as a parameter instead of a username and password. Prerequisites: Apache Maven. Download the required source code from GitHub: https://github.com/wso2/samples-is/tree/master/oauth2/custom-grant Custom-grant contains the source code for the mobile grant type that can be enhanced as per our requirement to configure the new grant type in WSO2 APIM.
