Build a WebAssembly Language for Fun and Profit: Lexing

Aggregated on: 2022-10-11 02:58:25

WebAssembly (wasm) is a high-performance assembly-like format optimized for the web. Code targeting WebAssembly can run at near-native speeds while still benefiting from the safe environment of a browser VM. Wasm has opened up a whole new world of demanding desktop-class apps that can comfortably run in the browser. For example, AutoCAD was able to port decades of code to the web using wasm. Cases like AutoCAD’s have made it clear that wasm will be a major disruptive force in how web apps are developed. To facilitate the adoption of wasm, WebAssembly team developed a powerful compiler toolchain library called binaryen. Binaryen does a huge amount of heavy lifting for compiler authors. It offers dead code removal, code size reduction, and various performance optimizations out of the box.

Kubernetes Services Explained

Kubernetes networking principles are really confusing, especially if you’re a beginner. Regardless of how well I followed the official documentation, I honestly didn’t understand a single damn thing!

Model Cards and the Importance of Standardized Documentation for Explaining Models

Aggregated on: 2022-10-11 01:28:25

Documentation is officially defined as material that provides official information or evidence that serves as a record. From a machine learning perspective, particularly with regard to a deployed model in a production environment, documentation should serve as notes and descriptions to help us understand the model in its entirety. Ultimately, effective documentation makes our models understandable to the many stakeholders we interact with.  Whether we are deploying low-impact models serving basic and non-sensitive needs or high-impact models with significant outcomes, such as loan approvals, we have a responsibility to be transparent—not just to our end users, but to our internal stakeholders. Furthermore, it shouldn’t just be the data scientists who hold all knowledge underpinning a model—it should be open, accessible, and understandable to anyone.

Open Banking Competitive Edge Through Data Architecture

Aggregated on: 2022-10-10 23:43:24

The banking system is changing. Rather than control everything themselves, financial service providers are looking at building a more horizontal system under the umbrella of a banking network.  Banks, insurance agencies, loan providers, and so on are looking at ways to integrate their services with other providers. It’s the magic of open banking — a system where banks use APIs to provide third-party developers and service providers with automated, secure access to customer data so they can offer tailored solutions. This modularization allows them to focus on providing specialized services while still giving customers a connected experience — a win-win for everyone.

How to Automate Certificate Issuance to Kubernetes Deployments Using Autocert

Aggregated on: 2022-10-10 23:13:24

In public web browsing, TLS authentication happens in one direction — only servers present their certificates. Serving public web pages without authenticating the client's identity is reasonable, but it isn't for Kubernetes. If other entities are going to be accessing sensitive data on services/clusters, then it makes sense that the identity of such entities should be validated too. Using TLS everywhere is one of the Kubernetes team's recommendations for hardening cluster security and increasing resilience.

The Memorable Power of Agile Storytelling

Aggregated on: 2022-10-10 21:43:24

I like reading books about corporate dysfunction when they come in the shape of a compelling (fictional) narrative. Business writers know how storytelling can spice up dry theory and support their argument. Patrick Lencioni’s The Five Dysfunctions of a Team and Gene Kim’s Unicorn and Phoenix projects are good examples. It works for popular science too. In Snakes in Suits, psychologist Robert Hare, a renowned authority on psychopathy, explains for a lay readership the manifestations and biological foundations of this dark human design flaw. He interweaves the science with a chilling fictional narrative of a parasitic young suit slithering his way up the corporate ladder. So, when a coworker told me the other day about an especially glib colleague who lied, cheated, charmed, and flunked his way to job security, I immediately thought: psycho! In software, any rule or recommendation, whether it’s the Law of Demeter, SOLID principles, or the Agile Manifesto is the distillation of years of experience, spirited discussion, and plenty of compromises. Observing how teams work has led us to certain recommendations that boil the specific down to the generic. Stories are a wonderful aid to explain and justify such rules because they can show how the rules were arrived at in the first place. They supply the back story that reconnects the specific back to the generic. You need these to know and respect the justifications behind a principle. It’s not enough to learn a rule by heart if you want to apply it well. Concise lists of opinionated statements make for pithy posters, but the necessary back story is missing from the text.

What Is Transaction Management in Java?

Aggregated on: 2022-10-10 16:43:24

Transaction Management in Java In this tutorial, we will discuss transaction management in Java using Examples. But before moving to Transaction management, we should know what transaction is, Therefore the following are some important points about transactions for better understanding: A transaction is a segment of program execution that accesses and can alter different pieces of data. A consistent database must be visible to a transaction. The database can briefly be unavailable during transaction execution inconsistent. The database is updated after the transaction is successfully completed (committed) and has to remain constant. A transaction's modifications to the database are finalized when it commits. Multiple transactions may run concurrently. There are two key challenges to address: Many types of failures, including hardware issues and system crashes. Execution of many transactions occurs simultaneously.  Types of Transactions Every SQL query will be regarded as a transaction in JDBC. A database connection created with JDBC will operate in auto-commit mode (auto-commit value is TRUE). The SQL statement will automatically be committed upon execution.

A Guide to Process Mapping for Seamless Software Testing

Aggregated on: 2022-10-10 15:43:24

A process map is a planning and management tool that visually illustrates the steps, details, and flow of a process. Software testing is an investigation done on software to gain insights into the quality of the software.  While many software developers may not want to admit it, the work of a Quality Assurance (QA) team in testing developers’ software is crucial to a software company. Customers would not be happy with a low-performance, buggy product or service (just imagine an automation testing process that doesn’t automate). But software testing can take time, and finding out the cause of a software bug can get difficult fast. This is where process mapping can help.

AWS Step Function for Modernization of Integration Involving High-Volume Transaction: A Case Study

Aggregated on: 2022-10-09 23:43:24

The serverless offerings of AWS (or any other public cloud provider today) are getting more and more popular. One of the biggest reasons is of course not needing to think about infra (server provisioning and so on). The other reasons include the offerings themselves, which at times fit well into the technical need for finding solutions to the given problems. But on the other side, it remains a challenge to know the offerings in detail to leverage them properly. There could be always some new feature hidden deep inside the bulk of the documentation. Background A retail company decided to leverage the AWS Serverless offering for modernizing their on-premises integrations for order management business process. We can go serverless in the cloud in various ways, but the initial solutioning was decided to leverage the Step Function and Lambda Function along with some more integration offerings from AWS, namely SNS, SQS, and EventBridge. 

Message Routing and Topics: A Thought Shift

Aggregated on: 2022-10-09 23:13:24

I started my engineering career with a messaging middleware company out of the Bay Area, California, that came around just when CORBA was being retired, giving rise to MoM and other middleware technologies. Integration problems were classified as internal (EAI) vs. external (B2B) integrations. Terms like Enterprise Dial-Tone and Enterprise Bus were coined to define the problem and exemplify integration solutions. Fun time, indeed!  We created a broker supporting concepts like Territories, Gateways, Adapters, and Visual Designer to design integrations, which I am proud to have been a part of. Performance was measured by message throughput, i.e., messages routed per second through the broker.  With constraints of the day around CPU power, storage, and memory, we were tinkering with TCP windows, swap and page size, memory-mapped IO, all the tricks around multi-threading, and whatnot to get the best performance. 

How to Change DAG Witness Server and Witness Directory

Aggregated on: 2022-10-09 14:58:24

Witness Server and Witness Directory are the most critical components of the Database Availability Group (DAG). DAG requires Witness Server or File Share Witness (FSW) and Directory to maintain the Quorum. In case of Witness Server failure, the Quorum is no longer maintained, leading to inconsistent DAG. In addition, the cluster may no longer respond or work, leading to downtimes if a disaster strikes. However, you can change the Witness Server and Witness Directory to maintain the Quorum and ensure high availability when the Witness Server has failed, is unavailable, or does not boot.

The Power of Open-Source RPA and Parallel Processing

Aggregated on: 2022-10-08 21:28:23

Over the past few decades, technology has made incredible leaps and bounds — from the creation of the internet to the development of AI. Waves of innovation have boosted enterprises’ productivity and reach, but with every new iteration, it becomes more complex to manage multiple technologies in your stack. A Brief History of Enterprise Technology Mainframes and customized homegrown platforms were the norm through the 1970s and 80s. ERP systems became the rage in the 90s and early 2000s. Most companies adopted these monolithic solutions to manage enterprise support functions and service delivery — and many still rely on them as core systems of record. 

Need an AI Monitoring Solution? Build vs. Buy

Aggregated on: 2022-10-08 21:13:23

There are many factors to consider when deciding whether to buy or build your AI monitoring system. Ultimately, it comes down to whether you can accomplish the outcomes you set out to achieve with ML monitoring, at a cost you can afford, and in a timely manner.  When It Makes Sense To Build 1. Your AI Program Is Immature; Your Needs Are Simple/Basic The need to monitor production AI often arises early, frequently before the company deployed its first ML models in the business. Data science teams universally understand the importance of visibility into data integrity and model fidelity over time, with the need for optimizations and improvements after deployment. However, in some cases, when you're still mainly experimenting or using only manual and offline processes, perhaps there is not a lot of data complexity, and perhaps the level of adoption in the business is still rather low, so the stakes are not very high. In these cases, these teams may just need a simple dashboard with basic alerting, and open-source tools such as Grafana or Kibana can address these needs at this point in time.

It's hard to operate stateful distributed systems at scale and Redis is no exception. Managed databases make life easier by taking on much of the heavy lifting. But you still need a sound architecture and apply best practices both on the server (Redis) as well as the client (application). This blog covers a range of Redis-related best practices, tips and tricks including cluster scalability, client-side configuration, integration, metrics etc. Although I will be citing Amazon MemoryDB and ElastiCache for Redis from time to time, most (if not all) will be applicable to Redis clusters in general.

5 Web Accessibility Myths

Aggregated on: 2022-10-07 19:13:23

Many websites which exist today are not accessible. This causes people with disabilities, especially those who use assistive technologies, to not interact with the web effectively. WebAIM conducted a study across the one million home pages and 50,829,406 distinct accessibility errors were detected—an average of 50.8 errors per page. According to UsableNet, web accessibility lawsuits are increasing in 2022 with almost 100 lawsuits per week. However, fear of litigation should not be the reason you should invest in web accessibility. There are over a billion disabled people on this planet and they should have the human right to access the web. Here are some of the myths which can stop companies and individuals from investing in proper web accessibility efforts: My Users Don’t Need It It is a mistake to assume that your users are not disabled and hence you don’t need to make your website accessible. However, it is important to keep in mind that most disabilities are invisible or non-apparent. According to Lime Connect, a disability organization in the US, 90% of disabilities on school campuses are invisible.  A vast majority of the disabled population does not even disclose that they have a disability. In addition to this, disabilities are also temporary and situational. For example, having a temporary hand injury and having to use speech to text. Designing software with accessibility in mind benefits everyone, not just people with disabilities. Think about captions. Initially, captions were invented to help the Deaf/Hard of Hearing population but many of us use captions almost always while watching Netflix!

Understanding Kafka-on-Pulsar (KoP): Yesterday, Today, and Tomorrow

Aggregated on: 2022-10-07 17:43:23

Apache Pulsar and Apache Kafka share a similar data model around logs. This makes it possible to implement a Kafka-compatible protocol handler so that Kafka users can migrate existing Kafka applications and services to Pulsar without modifying the code. It also allows these applications to leverage various Pulsar features such as multi-tenancy, infinite event stream retention, and serverless event processing. This is where the open-source project Kafka-on-Pulsar (KoP) comes in. Why Did the Community Develop KoP? To begin, I think it is important to answer a key question: “Why did you develop it?” As a maintainer of the KoP project, I notice that this is usually the first thing that comes to mind for a new community member. To answer this question, let’s have a quick look at the basics of Pulsar and Kafka.

Turbocharge Your Application Development Using WebAssembly With SingleStoreDB

Aggregated on: 2022-10-07 17:13:23

WebAssembly (Wasm) is a binary instruction format for a stack-based virtual machine. Wasm enables developers to use existing code from programming languages such as C, C++, and Rust as part of their application development process. However, Wasm is not just for the web, and today it is moving in exciting new directions. For example, one use-case would be to run Wasm code in a database system on the data already stored in the database system: an example of co-locating computation with data. Using Wasm to extend the capabilities of a database system opens up opportunities to develop many new applications. SingleStoreDB supports Wasm through Code Engine and, in this article, we'll see how to build a Wasm UDF to perform sentiment analysis on data already stored in SingleStoreDB. Introduction We'll need to perform a few steps to prepare our development environment, and the following sections will show how to do this. We'll also use Rust to create our Wasm UDF. Our code example will build upon the example described in the SingleStore blog post [r]evolution Summer 2022: Bring Application Logic to Your Data With SingleStoreDB Code Engine for Wasm.

Data Warehouse and Data Lake Modernization: From Legacy On-Premise to Cloud-Native Infrastructure

Aggregated on: 2022-10-07 15:28:23

The concepts and architectures of a data warehouse, data lake, and data streaming are complementary to solving business problems. Storing data at rest for reporting and analytics requires different capabilities and SLAs than continuously processing data in motion for real-time workloads. Many open-source frameworks, commercial products, and SaaS cloud services exist. Unfortunately, the underlying technologies are often misunderstood, overused for monolithic and inflexible architectures, and pitched for wrong use cases by vendors. Let's explore this dilemma in this article and learn how to build a modern data stack with cloud-native technologies.

Decorating Microservices

Aggregated on: 2022-10-07 13:58:23

The Decorator pattern is used to modify the behavior of a target component without changing its definition. This idea turns out to be pretty useful in the context of microservices because it can give you a better separation of concerns. It might even be necessary because the target service might be outside your control. This text looks at how a decorator can be implemented as a service, particularly one that sits between clients and a target service. Example: an E-mail Service Let's introduce an example as a reference for our discussion.

Keep Calm and Respond: A Beginner's Heuristic to Incident Response

Aggregated on: 2022-10-07 04:43:22

A few years ago, when working as a software developer building and maintaining internal platform components for a cloud company, I deleted an application from production as part of a deprecation. I had double and triple-checked references and done my due diligence communicating with the company. Within minutes, though, our alerting and monitoring systems began to flood our Slack channels, in a deluge of signals telling me something wasn’t working. The timing was pretty clear; I had broken production. In medical dramas, the moment when things are about to go wrong is unmistakable. Sounds are muffled. High-pitched, prolonged beeps take over your ears. Vision blurs. When alarms sound, or danger is near, something takes over within you. Blood drains from your head, heat rises in your body, and your hands sweat as you begin to process the situation. Sometimes you confront the issue, sometimes you try to get as far away as possible, and sometimes, you just freeze. In my case, with red dashboards and a sudden influx of noise, I had turned into the surgical intern holding a scalpel for the first time over a critical patient, with no idea what to do.

Deploy Apache Pulsar With MetalLB on K3s

Aggregated on: 2022-10-06 17:28:22

Apache Pulsar is a distributed messaging and streaming system. Its unique architecture of compute-storage separation is born for cloud-native environments. As we run Pulsar inside containers in production, we might want to run some tests beforehand. This is also why I tried installing Pulsar on Kubernetes through the KubeSphere App Store in a previous blog. In this blog, I would like to try another way of installing Pulsar in the containerized environment by using K3s. What Is K3s K3s is a lightweight Kubernetes distribution developed by Rancher. It gets rid of some dependencies and components required for Kubernetes. As such, you can run K3s on smaller machines compared with Kubernetes. This also makes it very easy to use for development and testing purposes (you can also scale it for production). If you are new to Kubernetes or are frustrated by its complexity, K3s may be a great alternative to get started.

How to Migrate From Kubernetes Pod Security Policies (PSPs) to Kyverno

Aggregated on: 2022-10-06 13:43:22

Since its genesis, Kubernetes has been the go-to container orchestration solution for enterprises needing scalable containerized applications implemented on microservices architecture. It essentially deals with the Pod as the most basic unit, which may hold one or more containers. Since any application deployed within Kubernetes is executed through one or more Pods, it is important for the user to ensure that they are secure from misconfigurations and security breaches. Thus, Pod security is not just a major concern but a necessity for Kubernetes clusters and even more for business-critical applications.  To fulfill this need, Kubernetes introduced PodSecurityPolicy in its v1.3 release. However, PodSecurityPolicy has been officially deprecated by Kubernetes in the v1.21 release and has been entirely removed in the v1.25 release, which was a step taken due to some major issues encountered by users throughout the years of its use that could not be addressed without introducing breaking changes (more details could be found on an official post made by Kubernetes).

Designing and Querying JSON in Databend

Aggregated on: 2022-10-05 20:43:22

JSON (JavaScript Object Notation) is a commonly used semi-structured data type. With the self-describing schema structure, JSON can hold all data types, including multi-level nested data types, such as Array, Object, etc. JSON takes advantage of high flexibility and easy dynamic expansion compared with the structured data types that must strictly follow the fields in a tabular data structure. As data volume increases rapidly in recent years, many platforms have started to use and get the most out of semi-structured data types (such as JSON). For example, the JSON data is shared by various platforms through open interfaces, and the public datasets and application logs are stored in JSON format.
