Aggregated on: 2023-05-21 16:45:37

If the name Foursquare rings a bell, it means you were around in the 2010s. Your only resort to plausible deniability would be if you are a data professional – although that’s not an either/or proposition. In the 2010s, Foursquare was a consumer-oriented mobile application. The premise was simple: people would check in at different locations and get gamified rewards. Their location data would be shared with Foursquare and used for services such as recommendations.

Using DuckDB With CockroachDB

Aggregated on: 2023-05-21 16:15:37

Motivation CockroachDB has native support for change data capture. It supports object storage sinks across all major cloud providers. At the time of writing, there are a couple of supported formats available like Avro and Newline Delimited JSON. Up until now, I've been avoiding Newline Delimited JSON because I don't find it easy to use. Today, I'd like to look at DuckDB as a viable tool to parse the CDC-generated output in newline-delimited format. High-Level Steps Start a CockroachDB cluster Parse CockroachDB newly-delimited changefeed output using DuckDB Query CockroachDB tables using DuckDB Conclusion Step-By-Step Instructions Start a CockroachDB Cluster I am using a serverless instance of CockroachDB. It has enterprise change feeds enabled by default. You can sign up for a free instance.

NestJS + Mongo + Typegoose

Aggregated on: 2023-05-19 23:45:36

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.

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

Aggregated on: 2023-05-18 23:30:35

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?

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

Aggregated on: 2023-05-18 23:00:35

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: 2023-05-18 23:00:35

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.

Beyond SCADA: Consolidating Your OT With an IIoT Platform

Aggregated on: 2023-05-18 18:45:35

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: 2023-05-18 14:15:35

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: 2023-05-18 02:30:35

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.

Why Using Generative AI for OKRs Is Generally a Bad Idea

Aggregated on: 2023-05-18 02:00:35

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.

Automation Testing Tools: The Top 15 for 2023 Plus How To Choose the Right One

Aggregated on: 2023-05-18 00:45:35

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: 2023-05-18 00:45:35

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/.

TDD vs. BDD: Choosing The Suitable Framework

Aggregated on: 2023-05-18 00:00:35

Most Software Developers in Test are familiar with Test-Driven Development, or TDD, but Behavior-Driven Development, or BDD, is often misunderstood. The truth is that both of these approaches have advantages and disadvantages to consider. This blog deep dives into TDD vs. BDD comparison by looking at both these approaches individually. Later, we would compare them to functionalities, supported frameworks, and more.I could say BDD is merely the evolution of TDD.

Data Quality Survey: Resolving Data Issues Takes 166% Longer Year Over Year

Aggregated on: 2023-05-18 00:00:35

The headline of the second annual The State of Data Quality survey was, without a doubt, the fact that data downtime nearly doubled year over year (1.89x). The Wakefield Research data quality survey, which was commissioned by Monte Carlo and polled 200 data professionals in March 2023, found three critical factors that contributed to this increase in data downtime. These factors included:

Text Classification With BERT

Aggregated on: 2023-05-17 23:30:35

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.
