Synchronizing Basic Product Data From MySQL With DolphinDB Cached Tables

Aggregated on: 2022-12-09 16:14:00

DolphinDB is a high-throughput distributed time-series database, specially designed for big data analysis scenarios in industrial IoT (IIOT) and finance. Data analysis in DolphinDB is often conducted based on the basic product information (such as the SKU, size, and storage of a device) from an external business platform, which conventionally runs on a relational database. To associate external product information with the time series data in DolphinDB, you can use the cached tables to save the external data fetched through plugins (MySQL, MongoDB, CSV file, etc.) in memory with regular synchronizations.

Simplifying A/B/n Testing of Backend Services

Aggregated on: 2022-12-09 14:44:00

A/B/n testing, or split testing, is a testing process by which user traffic is randomly distributed between two or more versions of an application (or application component). Business metrics are evaluated to identify a winning version — the version which results in the greater profit or business value. For example, a shopping application might use revenue and user engagement as business metrics. We focus on A/B/n testing of backend services deployed in Kubernetes. For example, in the figure below, the frontend might be a Node.js based online store. It relies on a backend recommendation service to make product suggestions to users. We are interested in A/B/n testing multiple versions of the recommendation service. In the figure, we have two versions, v1 (the current or default version) and v2 (the candidate version).

The State of Deepfakes in Cyber Attacks

Aggregated on: 2022-12-09 13:44:00

AI-generated deepfake content is all over the internet today and is getting harder to spot. These fake photos, videos, or audio clips can feature real and fictional people. Hackers and scammers have begun using this technology in elaborate cyber attack campaigns, from phishing attacks to interfering in national security matters. Here is a look at what deepfakes are, how they are made, and how AI systems are fighting deepfake cyber attacks. What Are Deepfakes? Deepfakes are heavily-doctored fraudulent video or audio clips that closely match a real person’s appearance, voice, intonation, and speaking patterns. Typically, the deepfake creator will use a machine learning algorithm to train an AI system using numerous video and audio samples. The AI essentially becomes an expert on the subject’s mannerisms to such a degree that it can create a believable fake clip of the person saying or doing things they have never actually done.

Top 5 Network Security Risks in 2023

Aggregated on: 2022-12-08 20:28:59

Network security refers to the technologies, processes, and policies used to protect networks, network traffic, and network-accessible assets from cyberattacks, unauthorized access, and data loss. Organizations of all sizes need network security to protect their critical assets and infrastructure. Modern network security takes a layered approach to protect the many edges of the network and the network perimeter. Any element of the network could be an entry point for attackers—endpoint devices, data paths, applications, or users. Because organizations face numerous potential threats, it is common to deploy multiple network security controls designed to address different types of threats at different layers of the network and infrastructure. This is called a defense in-depth security approach.

How to Choose the Right Messaging System for Your Organization

Aggregated on: 2022-12-08 20:13:59

In terms of messaging technologies, we have dozens of popular options on the market, while each of them may only support certain use cases in the queuing and streaming space. Before I explain how to choose the right messaging system, I think it’s worth taking some time to explain message queuing and streaming first. With a basic understanding of these concepts, we will then look at some core and advanced capabilities required for a messaging system for a modern data architecture. After that, I will give a high-level overview of Apache Pulsar, a cloud-native messaging and streaming platform, and explain what makes Pulsar suitable for some common messaging scenarios. Queuing: Decoupling A message queue (also known as a queue) is used to store messages with a first-in-first-out (FIFO) data structure. Messages stay on a queue until they are consumed by other applications or systems. Many programming languages have built-in message queues as data pipelines between tasks for asynchronous decouplings, such as java.util.Queue in Java.

12 Ways To Optimize Your JavaScript Journey in 2023 and Beyond

Aggregated on: 2022-12-08 20:13:59

JavaScript has emerged as the prominent scripting language among the next cohort of developers. It is an incredible tool for front-end programming, building interactive, feature-loaded websites, and fast and smooth web applications. Every front-end programmer knows JavaScript, however, when used without knowledge, it can make things worse. Poor JavaScript code can impact the website's performance, rendering speed, and load time. In this blog post, we will share some tips to help you optimize your JavaScript journey for the future. Let’s have a look: 1. Minify JavaScript code for small file — Minifying code is not similar to obfuscating code. However, both are ways of converting JavaScript — to be more complex to read or to make it smaller. Minifying accomplishes the latter and can shrink file sizes to reduce page load times. Line breaks, extra spaces, comments, etc., all increase the size of a JavaScript file and affects the pace at which the page loads. Minifying the code solves this problem.

Should You Learn Amazon RDS or DynamoDB?

Aggregated on: 2022-12-08 00:13:59

Modern-day application stores a lot of information and data to understand customer expectations and deliver personalized solutions. All these pieces of information are stored in databases. Now, developers can leverage data from databases using various methods. What confuses them most is the choice of service or method they need to pick in order to manage their database. They can pick either relational or non-relational methods of managing databases. In terms of tools and services, there exists a plethora of services in the market that developers can pick. All these options are enough to make a developer trip over! In this article, I have tried to address whether one should pick Amazon RDS or Dynamo DB. But before we can proceed to that, let’s have a quick look at the difference between relational and non-relational databases. Understanding Relational vs. Non-Relational Databases There are two different approaches to constructing a database — relational and non-relational databases.

How To Mitigate API Risks During Development

Aggregated on: 2022-12-07 23:13:59

It takes a lot of development time, quality assurance, and bug fixes to deploy a fully functional API. What most development teams skip is the security and risk management necessary to ensure the safety of the customer and corporate data after deployment. In many development teams, the security of the API is left to monitoring, logging, and future penetration testing. Unfortunately, this leaves the API vulnerable to attackers who can find exploits before you do. Instead of leaving security to after-deployment strategies, a “shift left” approach incorporates security scanning into current development lifecycles and has shown to be much more effective at reducing risks. Many Development Teams Skip Crucial Security Validation for Faster Code Deployment Deployment velocity (speed) is often a priority in enterprise API development. While rapidly deploying features to an API is important, developers might sacrifice security for speed, which leaves endpoints open to common exploits. This can be especially dangerous for organizations that process and return sensitive data using public-facing APIs.

Web Resource Caching: Server-Side

Aggregated on: 2022-12-07 20:43:59

The subject of Web resource caching is as old as the World Wide Web itself. However, I'd like to offer an as-exhaustive-as-possible catalogue of how one can improve performance by caching. Web resource caching can happen in two different places: client-side - on the browser and server-side. In the previous post, I explained the former; this post focuses on the latter. While client-side caching works well, it has one central issue: to serve the resource locally, it must first have it in the cache. Thus, each client needs its cached resource. If the requested resource is intensive to compute, it doesn't scale. The idea behind server-side caching is to compute the resource once and serve it from the cache to all clients.

Project Documentation: How to Guarantee Your Project Endures With High Quality

Documentation, I know, right now, you are preparing to leave this post. Documentation is not a buzzword topic, such as microservices, Kubernetes, cloud-native, etc. However, it guarantees a scalable, maintainable, and healthy project. Let's explain how to keep a better project tactically through Documentation. Why Do We Need Documentation? The first question around Documentation is why. Why should you spend time on Documentation instead of the code? Software development is expensive, and we must ensure this project will have a long life. To make it possible, we need to make life easier for a future engineer, who eventually might be yourself.

Almost all programming languages have support for regular expressions and use a common set of special characters to define them. Let's try out some example regular expressions.

Projections/DTOs in Spring Data R2DBC

Aggregated on: 2022-12-07 19:43:58

When dealing with Spring Data JPA or Spring Data R2DBC, we all know that everything revolves around entities. You usually create a repository, and in most cases, it either extends the JpaRepository<T, ID> for Spring Data JPA or the R2dbcRepository<T, ID> for Spring Data R2DBC, and then you’re ready to talk to the database. With the repository in place, things are pretty straightforward: you either use the standard already-provided interface methods, you write derived-query methods, or you can use the @Query annotation to write custom stuff. Up until here, everything’s nice. As I said, everything revolves around entities (with minor exceptions, you can get a primitive return type with a custom query like an Int or String), so as a response, you’ll always get an Entity/List<Entity> for JPA and Mono<Entity>/Flux<Entity> for R2DBC. However, there are certain scenarios when you either don’t want to fetch the entire entity because some columns are redundant/not-needed or, even more, you need to construct a POJO from something completely different from your entity, yet still somehow related. Think about a group by, some counts, or some mapping at the database level, and by default you can’t do that – your repos are bound to entities. That is when projections and DTOs come into play. For Spring Data JPA there is already a fair amount of documentation/info around (official documentation, Vlad Mihalcea, Thorben Janssen, and so on). This is not the case when it comes to Spring Data R2DBC (we still have amazing documentation here).

Control Your Kubernetes Cluster Compute Resources With ResourceQuota

Aggregated on: 2022-12-07 02:58:58

A Word About Kubernetes Cluster Resources Kubernetes is a container orchestration platform. It is very popular for deploying container-based workloads. Kubernetes clusters could spread across many nodes. These nodes are physical or virtual machines spread across geographies and deployed at various data centers, ensuring high availability for the cluster. These machines have a lot of computing resources aggregated at the cluster level and are at the disposal of the workloads that get deployed in the cluster. These computing resources include CPU and memory capabilities. Apart from that, the cluster also has a constraint on the number of API objects it can hold. The latest Kubernetes version supports 110 pods per node, as there are also constraints on assigning IP addresses.

A Maven Archetype for Jakarta EE 10 Applications

Aggregated on: 2022-12-06 22:58:58

Jakarta EE 10 is probably the most important event of this year in the Java world. Since this fall, software editors providing Jakarta EE-compliant platforms are working hard to validate their respective implementations against the TCK (Technology Compatibility Kit) supplied by the Eclipse Foundation. At Payara, as much as in bigger companies like Oracle, Red Hat, or IBM, they aren't left behind, and, as of last September, they announced the availability of the Payara 6 Platform, declined in three versions: Server, Micro, and Cloud. As an implementation of Jakarta EE 10 Web, Core, and Micro Profile, Payara Server 6 is itself proposed in two editions: Community and Enterprise. But how does this impact Java developers? What does it mean in terms of application development and portability? Is it easier or more difficult to write and deploy code compliant to the new specifications than it was with Release 9 or 8 of the Jakarta EE drafts? Well, it depends. While any new Jakarta EE release aims at simplifying the whole bunch of the API (Application Programming Interface) set and at facilitating the developers' work, the fact that, on a total of 20 specifications, 16 have been updated, and a new one has been added, shows how dynamic the communities and the working groups involved in this process are. Which isn't without some difficulties when trying to transition to the newest releases with a minimal impact.

Docker Best Practices

In this blog, you will learn some Docker best practices mainly focussed on Java applications. This is not only a theoretical exercise, but you will learn how to apply the best practices to your Dockerfiles. Enjoy! 1. Introduction Writing Dockerfiles seems easy: just pick an example from the internet and customize it to fit your needs. However, many examples are good for a development environment but are not production worthy. A production environment has more strict requirements especially concerning security. Besides that, Docker also provides guidelines for writing good Dockerfiles. It is just like writing code: you may know the syntax, but that does not mean you can write clean and good code in that specific programming language. The same applies to Dockerfiles. With this blog, you will learn some best practices, guidelines you can apply when writing Dockerfiles. The previous sentence deliberately says can apply and not must apply. It all depends on your use case.

How To Use ggshield To Avoid Hardcoded Secrets [Cheat Sheet Included]

Aggregated on: 2022-12-06 19:13:58

Most developers love working in the terminal, tying together all sorts of tools with command line interfaces, CLIs, via scripting. Working with CLIs is powerful, but it can be challenging to initially learn all the ways a tool can help you do your work. While the only real way to learn any tool is by using it, one time-tested method to get over the learning curve is to keep a short list of common commands, as well as concept recaps, on hand for using the tools. At the same time, it is pretty common to adopt a tool for one or two specific functions, without investigating what other commands a tool offers. For example, just think about how many Git commands you use regularly out of the 164 currently available commands. Getting a holistic view of how a command line tool is structured and the possible commands can help you make better use of the platform.

Starting from a set of requirements we need to implement, we have preferences that we should first write code and then test; on the other side, we have the TDD approach emerging for years now, as well as some other approaches (design-first, etc.). Here I want to explain one approach that I find to work very well when designing and implementing software, especially if it is a component or library. The main question here is how you start designing your code. Do you start with some kind of drawing, write tests first (TDD), or start imidate with an implementation?

Securing Developer Tools: A New Supply Chain Attack on PHP

Aggregated on: 2022-12-06 04:43:58

Supply chain attacks are a hot topic for development organizations today. Last year, in the largest ever software supply chain attack, a backdoor infected 18,000 SolarWinds customers. Earlier this year, a security researcher was able to breach Apple, Microsoft, PayPal, and other tech giants using a new supply chain attack technique. The underlying design exploited by these attacks is that all modern software is built on top of other third-party software components, often without clear visibility of all the downloaded packages. And while reusing many components allows to speed up the development process, infecting the supply chain is a very effective and subtle attack vector to compromise many organizations at once.

The digital transformation and cloud-native movements are driving DevOps practices and open-source code libraries increase the speed at which applications are developed and delivered. However, security has not always been a top priority in the DevOps journey. In order to ensure that applications are secure, it is essential to make security a part of the process. Organizations can achieve this integration by including security in the development process, automating security tasks, and fostering a culture of security throughout the entire organization. I’ll outline five current trends shaping the future of application security and how modern AppSec programs can get ahead of the curve by reducing developer friction, integrating security into CI/CD pipelines, and making security a first-class citizen of software development workflows. By understanding and acting on these trends, organizations can make security a more integral part of their software development process.
