Using OAuth in API Integrations With Python, REST, and HL7 FHIR

Aggregated on: 2022-10-20 00:43:30

OAuth is often employed in processes requiring permissions to be granted to front-end applications and end users. Yet what we typically need in API systems integrations is a way to secure connections between the integration middleware and backend systems without a need for any ongoing human interactions. OAuth can be a good choice for that scenario. This article shows how it can be achieved in Python with backend systems using REST and HL7 FHIR.

Trick the JVM for Maximum Performance With Megamorphic Call Sites

Aggregated on: 2022-10-19 18:58:30

The JVM does great stuff to let our Java applications run the fastest way possible. Most of the time, you don't have to care about the internals, but if you really need to get the best performance, you need to take into account how JVM works. It's not the goal of this article to give a detailed introduction to this topic but merely to show how our design can impact performance and how you can work around some issues which arise. An important aspect of performance optimization is inlining, i.e. the JIT replaces a method call with the code that will be executed by the method. For that to work, the method must be short, and it must be clear what the method is called. This is unfortunately not trivial as basically all methods can be overloaded, so the JVM does some run-time analysis and then makes some predictions. It basically distinguishes between monomorphic call sites, which always call the same method; bimorphic ones, which are optimized for two different targets; and call sites calling with more than two targets, which are called megamorphic, where fewer optimizations are applied. This analysis and the resulting optimization are done for each call site individually.

Can You Beat the AI? How to Quickly Deploy TinyML on MCUs Using TensorFlow Lite Micro

Aggregated on: 2022-10-19 17:58:30

Are you curious about artificial intelligence (AI) and machine learning (ML)? Do you want to know how to use it on the microcontrollers you already work with? In this article, we provide you with an introduction to ML on microcontrollers. This topic is also known as tiny machine learning (TinyML). Get ready for losing against an ESP-EYE at the rock, paper, scissors. You will learn about data collection and processing, how to design and train an AI and how to get it running on the MCU. This example provides you with all you need to do your own TinyML project from start to end. Why Should I Care About TinyML? Surely you’ve heard of tech companies such as DeepMind and OpenAI. They dominate the ML domain with experts and GPU power. To give a sense of scale, the best AIs, such as those used by Google Translate, need months of training. They use hundreds of high-performance GPUs in parallel. TinyML turns the tables somewhat by going small. Because of memory limitations, large AI models don’t fit onto microcontrollers. The figure below shows the disparity between the hardware requirements.

I also discussed the teams that these players are on in this world of cloud-native o11y. For the third article, I looked at the ongoing discussion around monitoring pillars versus phases.

Nearest Neighbor Embeddings Search With Qdrant and FiftyOne

Aggregated on: 2022-10-19 13:13:30

Neural network embeddings are a low-dimensional representation of input data that gives rise to various applications. Embeddings have some interesting capabilities, as they can capture the semantics of the data points. This is especially useful for unstructured data like images and videos so that you can encode not only pixel similarities but also some more complex relationships. Embeddings from the BDD100K dataset were visualized using FiftyOne and Plotly. Performing searches over these embeddings gives rise to many use cases like classification, building up recommendation systems, or even anomaly detection. One of the primary benefits of performing a nearest-neighbor search on embeddings to accomplish these tasks is that there is no need to create a custom network for every new problem; you can often use pre-trained models. Using the embeddings generated by some publicly available models is possiblewithout any further finetuning.

The Heart of the Data Mesh Beats Real-Time With Apache Kafka

Aggregated on: 2022-10-19 03:28:29

If there were a buzzword of the hour, it would undoubtedly be "data mesh!" This new architectural paradigm unlocks analytic and transactional data at scale and enables rapid access to an ever-growing number of distributed domain datasets for various usage scenarios. The data mesh addresses the most common weaknesses of the traditional centralized data lake or data platform architecture. And the heart of a decentralized data mesh infrastructure must be real-time, reliable, and scalable. Learn how the de facto standard for data streaming, Apache Kafka, plays a crucial role in building a data mesh. There Is No Single Technology or Product for a Data Mesh! This post explores how Apache Kafka, as an open and scalable decentralized real-time platform, can be the basis of a data mesh infrastructure and — complemented by many other data platforms like a data warehouse, data lake, and lakehouse — solve real business problems.

CockroachDB TIL: Volume 10

Aggregated on: 2022-10-19 01:28:29

This is my series of articles covering short "today I learned" topics as I work with CockroachDB. Read the previous installments: Volume 1 Volume 2 Volume 3 Volume 4 Volume 5 Volume 6 Volume 7 Volume 8 Volume 9 Topics Topic 1: Generating ULID strings in CockroachDB Topic 2: Enable CLI tab completion for column names Topic 3: Using Postico with CockroachDB Serverless Topic 4: Nuances with DISCARD ALL Topic 5: Npgsql and follower reads Bonus Topic: Npgsql and pgpass Topic 1: Generating ULID Strings in CockroachDB CockroachDB adopted ULID several releases ago as yet another version of UUID type. There is no explicit ULID type in CockroachDB. There are functions available to generate ULID in UUID format. So in case you need to generate lexicographically sortable IDs, you can use the built-in gen_random_ulid() function. Also, there are several conversion functions to convert from ULID to UUID; i.e., ulid_to_uuid and vice versa, uuid_to_ulid. One point of friction in CockroachDB is where one needs to generate an actual ULID string and not a UUID-formatted ULID. This may or may not be obvious. Let's take a look:

Angular 11 + Firebase Cloud Messaging Push Notifications

Aggregated on: 2022-10-18 22:28:29

What Are Push Notifications? A push notification is a popup message similar to an SMS. Push notifications work the same as SMS text messages and mobile alerts.  This provides the ability to receive messages pushed to them from a server, whether or not the web app is in the foreground, or even currently loaded, on a user agent. Second, look for versions needed for Push Notifications

HTTP-Based OOP, Inheritance, and Polymorphism

Aggregated on: 2022-10-18 20:28:29

This might sound like a joke, but it's actually not. First, let's define inheritance. Inheritance is the ability to use polymorphism to override a method with another implementation. You inherit from a class, and you override one of its virtual functions. This results in that code having an object that will no longer invoke the old base class method, but rather the new overridden method. Kind of easy, right? Polymorphism Is the Ability To Have Old Code Invoke New Code Well, there's nothing intrinsically special about class-based OOP that prevents you from implementing the above in a functional context. In a functional programming language, you can have a reference to a function, and replace the function it's pointing to, before passing in your function reference to some method in need of a function with the specified signature. This achieves the exact same result as "classic polymorphism."

Reducing React Dev Server to 213ms — From Create React App to Vite v3 Migration

Aggregated on: 2022-10-18 17:13:29

Developer experience is important. Having a fast and reliable development and build solution is important as the code that is written and how it performs. Recently, I saw a significant slow-down in a react app that its development and build system was based on the latest CRA package (create react app/react-script). I improved the developer experience in both development and build for production from afew seconds to a mere 213ms from 3277ms (dev server) —  That's an improvement of 95% in server uptime. In this article, I share my steps for migrating CRA (create react app) to use Vite while highlighting the benefits.

Avoid Data Silos in Presto in Meta: The Journey From Raptor to RaptorX

Aggregated on: 2022-10-18 16:43:29

Raptor is a Presto connector (presto-raptor) used to power some critical interactive query workloads in Meta (previously Facebook). Though referred to in the ICDE 2019 paper Presto: SQL on Everything, it remains somewhat mysterious to many Presto users because there is no available documentation for this feature. This article will shed some light on the history of Raptor and why Meta eventually replaced it in favor of a new architecture based on local caching, namely RaptorX. The Story of Raptor Generally speaking, Presto, as a query engine, does not own storage. Instead, connectors were developed to query different external data sources. This framework is very flexible, but it is hard to offer low latency guarantees in disaggregated compute and storage architectures. Network and storage latency adds difficulty in avoiding variability. To address this limitation, Raptor was designed as a shared-nothing storage engine for Presto.

An Overview of the Tools for Developing on Flow & Cadence

Smart contract development is no different than other types of software development. Code is written to perform a certain task, and there are tools that help make this process easier. The Ethereum ecosystem contains many mature tools to help build Web3 projects, but what about a newer ecosystem, such as Flow? If you’ve been following along with this series so far, you’ll know that the Flow blockchain is optimized for digital asset creation and management. Additionally, its smart contract language, Cadence, improves upon other languages’ pitfalls through its resource-based approach and a strong, static type system.

Debezium Server With PostgreSQL and Redis Stream

Aggregated on: 2022-10-17 21:43:28

Debezium is a great tool for capturing the row-level changes that happen on a Database and streaming those changes to a broker of our choice. Since this functionality stays within the boundaries of a Database, it helps on keeping our applications simple. For example, there is no need for an application to emit events on any database interactions. Debezium will monitor the row changes and will cast the events. Based on the broker solution used with Debezium a consumer can subscribe to the broker and thus receive the changes.

Compatibility of GitLab on CockroachDB and YugabyteDB (II) — Read and Write Scenario Testing

Aggregated on: 2022-10-17 19:58:28

In the previous article, "System Initialization," we concluded that CockroachDB could not be started because it could not automatically create database schema through GitLab's setup program, while YugabyteDB could start GitLab normally with all normal initialization steps. In this test, we first imported a standard GitLab library and the underlying data into these two databases to see if GitLab could be started typically. Then we selected a part of GitLab's core business scenarios to do a comparison test to see how compatible they are.

Making of Unreliable Systems

Aggregated on: 2022-10-17 17:43:28

Knowing anti-patterns and pitfalls is often more useful than knowing patterns when designing a system, so I decided to write this blog post about factors that I think will lead to producing unreliable systems from my experiences in designing (mostly) distributed enterprise applications.I’ll be pleased to know your related experiences and comments on the matter. What Is Modeling? The human brain is a pattern-seeking device. However, it’s a costly process, and the main goal of thinking is to terminate/resolve what caused this process to start in the first place; so it has developed several mechanisms to prevent it from happening too often; the one related to our discussion here is the mental model. Reality is complex, chaotic, and too messy for our limited brain capabilities and resources to comprehend as it is (if that’s even possible); so our minds will try to create an alternative reality which is very simple and (most of the time) easily understandable, and that’s what modeling is all about! from how we think about how nature works, in science for example, to proper social behavior, to what to be afraid of or seek for, all are the results of our mental model. It is noteworthy that models are neither objective reality nor meant to be so!

I discussed tracepoints quite a bit in my blog and videos. They are wonderful, but I feel the nuance of non-breaking is a bit lost. The true power of this amazing tool is hidden due to our debugging habits and our preconceived notions about debugging. It’s indeed difficult to make the mental shift required for these tools. The payoff for that mental shift is tremendous when dealing with “weird” bugs. Especially in large systems and with concurrency related issues. Let’s go back to the basics.

Microfrontends: Microservices for the Frontend

Aggregated on: 2022-10-15 17:43:27

Microservices are a popular way to build small, autonomous teams that can work independently. Unfortunately, by their very nature, microservices only work in the backend. Even with the best microservice architecture, frontend development still requires a high degree of interdependence, and this introduces coupling and communication overhead that can slow down everyone. Can we take microservice architecture patterns and apply them to the frontend? It turns out we can. Companies such as Netflix, Zalando, and Capital One have pushed the pattern to the front, laying the groundwork for microfrontends. This article will explore microfrontends, their benefits and disadvantages, and how they differ from traditional microservices.

This article looks at a benchmark passing events over TCP/IP at 4 billion events per minute using the net.openhft.chronicle.wire.channel package in Chronicle Wire (open source) and why we aim to avoid object allocations.  One of the key optimisations is creating almost no garbage. Allocation is supposed to be a very cheap operation, and garbage collection of very short-lived objects is also very cheap. Does not allocating really make such a difference? What difference does one small object per event (44 bytes) make to the performance in a throughput test where GC pauses are amortised?

If you are planning to start a blog of yourself, you may use this list of benefits in order to get you motivated to get started. 1. Introduction In the beginning of September, I already celebrated the fifth anniversary of my blog. Now I publish my 100th blog and I am pretty proud of it. It seems not so long ago that I started my blog, but on the other hand, it also feels like I am doing this for a long time. At least, I cannot imagine a life without my blog anymore. In the beginning, I really suffered of the imposter syndrome: I posted blogs, but did not let anyone in my direct environment know that I had a blog. After a few months, I let this feeling behind myself and let the world know that I write technical content. In those five years, I only had one or two negative comments, but many positive comments and I really do not bother about the negative ones. In the next section, I will try to list some of the benefits of a technical blog and if you would like to start with a blog yourself, do read Why Start a Technical Blog.

Tips for Developing a Screen Recorder

Aggregated on: 2022-10-15 03:13:27

Let's face it. Sometimes it can be difficult for our app users to find a specific app function when our apps are loaded with all kinds of functions. Many of us tend to write up a guide detailing each function found in the app, but — honestly speaking — users don't really have the time or patience to read through long guides, and not all guides are user-friendly, either. Sometimes it's faster to play about with a function than it is to look it up and learn about it. But that creates the possibility that users are not using the functions of our app to its full potential. Luckily, making a screen recording is a great way of showing users how functions work, step by step.

Using Databases With High-Performance Event Streaming: Critical Considerations

Aggregated on: 2022-10-15 02:43:27

In an earlier article I talked about comparing distributed databases in general. All of those considerations remain salient for choosing a database right for your use case. Yet for today, let’s focus in on a particular aspect of capability: whether a database is a strong fit for an event streaming architecture.  The transition from batch-oriented processing to event streaming architectures is at the heart of what’s fundamentally shifting in this next tech cycle. Kafka was initially released in 2011, around the same era as the early NoSQL databases. Pulsar was slightly later, being invented at Yahoo in 2013. Many database architectures long predate the event streaming revolution, and their fundamental design decisions may be an anti-pattern for use with event streaming.

The journey to a comprehensive data protection strategy should include a focus on enabling the business through security best practices and specific data protection use cases that are relevant. In essence, secure the data today while building and implementing the overall data protection plan for the future. This article highlights three specific data protection use cases that can be implemented as part of an overall strategy. To summarize these use cases: Insider threats: Detect and prevent malicious insiders from data exfiltration Phishing attacks: Mitigate impersonation with multi-factor authentication Data leaks: Detect and mitigate overexposed resources and assets A General Approach to Data Protection Data protection is a critical issue for all organizations that use the cloud to store data electronically. The goal of a comprehensive data protection strategy is to ensure the security and confidentiality of an organization's data while minimizing the impact of data breaches. There are a number of technical and organizational measures that can be taken to protect data. In general, these measures include data encryption, data backup and recovery, access control, and user education. 

Learn Database Read/Write Splitting Using Your Browser

Aggregated on: 2022-10-14 16:58:27

Read/write splitting is a technique to route reads and writes to multiple database servers, allowing you to perform query-based load balancing. Implementing this at the application level is hard because it couples code or configuration parameters to the underlying database topology. For example, you might have to define different connection pools for each server in the database cluster. MariaDB MaxScale is an advanced database proxy that can be used as a read/write splitter that routes SELECT statements to replica nodes and INSERT/UPDATE/DELETE statements to primary nodes. This happens automatically without having to change your application code or even configuration—with MaxScale, the database looks like a single-node database to your application.
