Apache Kafka vs. Message Queue: Trade-Offs, Integration, Migration

Aggregated on: Thu May 18 2023 23:00:35 GMT+0000 (Coordinated Universal Time)

A message broker has very different characteristics and use cases than a data streaming platform like Apache Kafka. A business process requires more than just sending data in real time from a data source to a data sink. Data integration, processing, governance, and security must be reliable and scalable end-to-end across the business process. This blog post explores the capabilities of message brokers, the relation to the JMS standard, trade-offs compared to data streaming with Apache Kafka, and typical integration and migration scenarios. A case study explores the migration from IBM MQ to Apache Kafka. The last section contains a complete slide deck that covers all these aspects in more detail. Message Broker vs. Apache Kafka -> Apples and Oranges TL;DR: Message brokers send data from a data source to one or more data sinks in real-time. Data streaming provides the same capability but adds long-term storage, integration, and processing capabilities.

How To Check IP Addresses for Known Threats and Tor Exit Node Servers in Java

Aggregated on: Thu May 18 2023 23:00:35 GMT+0000 (Coordinated Universal Time)

Without the existence of Internet Protocol (IP) addresses to organize and route server-to-server communication across the globe, it’s hard to imagine how the digital world would stay on its axis. Much in the same way our physical home and work addresses are required to direct the transport of physical products (i.e., letters and parcels) across county, state, and country lines, IP addresses necessarily facilitate the transfer and receipt of digital resources, representing the essential location and identification information that all reliable server communication depends on. Like the post office in our building, or the mailbox next to our driveway, the edge of our computer network receives a wide variety of messages from external IP addresses, and the devices originating those messages are generally traceable based on their unique address. Tracking and storing IP address information is beneficial for several reasons — like storing customer demographic information, for example — but it also plays a crucial role in bolstering network security efforts. The reality is that external servers requesting our resources are provisioned with unpredictable motivations, most often well-intentioned but also, at times, malicious. As a result, ensuring the security of our system against client-side threat actors starts with evaluating what threatening IP addresses are and what policies we can put in place to weed out addresses with discernably malicious motivations.

AWS Multi-Region Resiliency Aurora MySQL Global DB With Headless Clusters

Aggregated on: Thu May 18 2023 19:45:35 GMT+0000 (Coordinated Universal Time)

A headless cluster in Amazon Aurora global database refers to a cluster that has no database instance attached to it. In other words, the cluster only includes the database storage and is used as a backup in case of a failure of the primary cluster. The primary cluster is the one that has a database instance attached to it and is serving the application's read and write requests. The headless secondary cluster is used for disaster recovery and to provide high availability for the database. The data in the primary cluster is automatically replicated to the headless secondary cluster, so in case of a failure, the secondary cluster can take over as the primary cluster and provide a seamless transition with minimal disruption. In this article, we will see how to perform a failover with a headless Aurora Global Database and its outcomes.

But as the number of microservices increased and application pods are distributed across multiple clusters and cloud providers, managing and scaling them has become complex. While scaling, it is harder to configure complex communication logic between microservices. Also, there are additional concerns like securing and observing these connections. Without a proper management system for communication, service downtime and security breaches among distributed services become common.

Beyond SCADA: Consolidating Your OT With an IIoT Platform

Aggregated on: Thu May 18 2023 18:45:35 GMT+0000 (Coordinated Universal Time)

Industrial enterprises use SCADA as a process control system to monitor data acquisition processes and oversee various related workflows. The data coming from OT devices is taken in by SCADA systems and integrated into the SCADA ecosystem as applications covering a range of use cases for the shop floor. So why does an industrial IoT platform still make sense here? One downside of SCADA is that these systems are not made for rapid scaling. They do not accommodate change so easily. Most of the time, the processes are slow and inflexible. Further, the data collection processes, though robust, have their limitations. They are usually only suited for monitoring, supervision, and sending out alerts at best. More sophisticated analytics or use cases based on machine learning are out of reach.

Why `fsync()`: Losing Unsynced Data on a Single Node Leads to Global Data Loss

Aggregated on: Thu May 18 2023 14:15:35 GMT+0000 (Coordinated Universal Time)

In this deep dive blog post, I will be exploring the critical and often misunderstood dynamics of data loss within replicated systems. Our main focus will be on the potentially catastrophic impact of losing unsynchronized data on a single node that could cause global data loss. In the end, I will illustrate it with a demo. What Is fsync? By default, the disk write API is asynchronous. Therefore, when an application uses the operating system’s API to write data to disk, the OS copies the data and may confirm the write request without waiting for the data to reach the disk. This behavior improves latency and throughput, but it reduces safety.

The Native Way To Configure Path Aliases in Frontend Projects

Aggregated on: Thu May 18 2023 02:30:35 GMT+0000 (Coordinated Universal Time)

About Path Aliases Projects often evolve into complex, nested directory structures. As a result, import paths may become longer and more confusing, which can negatively affect the code’s appearance and make it more difficult to understand where imported code originates from. Using path aliases can solve the problem by allowing the definition of imports that are relative to pre-defined directories. This approach not only resolves issues with understanding import paths but also simplifies the process of code movement during refactoring.

Why Using Generative AI for OKRs Is Generally a Bad Idea

Aggregated on: Thu May 18 2023 02:00:35 GMT+0000 (Coordinated Universal Time)

Setting objectives and key results (OKRs) is a powerful way to align an organization's efforts toward a common goal. However, as the amount of data and complexity of objectives increase, it can become challenging to set effective and achievable goals. One solution that has gained popularity in recent years is to use generative artificial intelligence (AI) to automate the OKR creation process. While this may seem like a convenient and efficient solution, it comes with significant security implications that organizations need to consider. Generative AI for OKRs: The Basics Generative AI is a type of machine learning algorithm that can create new data from existing data. In the context of OKRs, this means that the AI can generate new objectives and key results based on the historical data and patterns it has learned from an organization's past performance. This can save time and effort for managers who would otherwise need to manually analyze data and create objectives based on their insights.

Although manual testing is still a powerful tool in software quality assurance, as we’ve established once again in our recent long read on manual vs. automated testing, more and more companies rely on testing automation for all-encompassing coverage and cost-effective QA. And automated testing tools are the key component of a well-designed testing process. By one estimate, 26% of organizations struggle with finding the right tool for a test automation project. It can happen for a myriad of reasons, from having trouble matching the QA team to the tool to being determined to work with a free solution even though there aren’t any that fully meet the needs of the project. This is why the process of selecting the toolset for an automation QA project needs to be treated with care.

A Deep Dive Into Apache Parquet With ClickHouse — Part 1

Aggregated on: Thu May 18 2023 00:45:35 GMT+0000 (Coordinated Universal Time)

Since its release in 2013 as a columnar storage for Hadoop, Parquet has become almost ubiquitous as a file interchange format that offers efficient storage and retrieval. This adoption has led to it becoming the foundation for more recent data lake formats, e.g., Apache Iceberg. In this blog series, we explore how ClickHouse can be used to read and write this format before diving into the Parquet in more detail. For more experienced Parquet users, we also discuss some optimizations that users can make when writing Parquet files using ClickHouse to maximize compression, as well as some recent developments to optimize read performance using parallelization. For our examples, we utilize the UK house price dataset. This contains data about prices paid for real estate property in England and Wales from 1995 to the time of writing. We distribute this in Parquet format in the public s3 bucket s3://datasets-documentation/uk-house-prices/parquet/.

Text Classification With BERT

Aggregated on: Wed May 17 2023 23:30:35 GMT+0000 (Coordinated Universal Time)

What Is Text Classification? Text classification is a machine learning subfield that teaches computers how to classify text into different categories. It's commonly used as a supervised learning technique, which means that the algorithm is trained on a set of texts that have already been labeled with their respective categories. Once it's been trained on this data, the algorithm can use what it's learned to make predictions about new, unlabeled texts. The algorithm looks for patterns in the text to determine which category it belongs to. It's like when learning to recognize a certain type of flower — we start to notice certain features that distinguish it from other types of flowers. With text classification, the algorithm is doing the same thing but with words and phrases instead.

Safeguarding Your Data Under GDPR Regulations

Aggregated on: Wed May 17 2023 14:30:34 GMT+0000 (Coordinated Universal Time)

GDPR, or the General Data Protection Regulations, is a set of rules that dictate how organizations store and use personal data. Since being introduced in 2018, GDPR has become the center of attention in data protection. Primarily due to how strict and incomprehensible this regulation is. But it is pretty understandable, as personal data should not be handled carelessly. The principles of GDPR emphasize the lawful processing of personal data and its protection. Under GDPR, businesses are legally required to protect the personal data of individuals, and non-compliance with these regulations can cost the company dearly. In this blog, we will guide you through the seven principles of GDPR and what measures companies can take to safeguard your data. Many business owners consider the expansion of their company to an international level to be a tremendous achievement. However, the GDPR, like many previous stepping stones, stands in the way of further success. As a result, GDPR is one of the strictest data privacy rules in the world today. However, you will have an easy ride if your organization can crack and comprehend the GDPR principles.

How Enterprises Are Enhancing the Digital Experience by Leveraging Observability

Aggregated on: Wed May 17 2023 03:15:34 GMT+0000 (Coordinated Universal Time)

In the beginning, IT teams utilized Application Performance Monitoring (APM) and Network Performance Monitoring (NPM) as tools to oversee and diagnose problems at the application and infrastructure levels. However, with the advent of contemporary development practices, the introduction of numerous distributed components made it difficult for APM and NPM solutions to offer complete visibility across the entire system. As a result, observability emerged as the logical successor to APM and NPM, owing to its capacity to provide comprehensive visibility within a distributed IT system. Through observability, businesses can take proactive measures to resolve production-level issues.

When you publish your website, you are always a bit concerned about its security of it. From a security point of view, an SSL certificate plays a major role to authenticate the identity of the website. SSL stands for Secure Socket Layer, which creates a secure tunnel between the web server and the client browser to keep online transactions private. In another way, it prevents hackers from reading or modifying information transferred between two systems. It is always recommended to check the padlock next to the website you are visiting. If it exists means visiting the website is secure to connect. I wrote another article on SSL certificates. This article describes how to get a free SSL certificate by using Window Server CA. You can use this for internal communication in a lower environment.

As a machine learning engineer and developer evangelist, my job is to listen to our open-source community and bring them what they need — new features, integrations, tutorials, workshops, you name it. A few weeks ago, we added native support for vector search engines and text similarity queries to FiftyOne, so that users can find the most relevant images in their (often massive — containing millions or tens of millions of samples) datasets via simple natural language queries.

When you think of Milwaukee, you might think of squeaky cheese curds, polka music, and the Bronze Fonz. But now, I will always associate this city on the lake with cybersecurity, thanks to Cyphercon 6, which was held on March 30 and 31, 2023. This year there were nearly 1500 participants, making it the largest security or technology conference in Wisconsin. Cyphercon is a 'hacker conference' much like Schmoocon or DEFCON. While there are sessions, the event also focuses on villages and capture-the-flag competitions. Unique among conferences I have attended, the first day started after lunch and ran until 10:30 pm, when the networking after-party officially started.
