Cloud Cost Management Alone Won’t Fix Your Cloud Spend Problem

Aggregated on: 2021-12-11 15:19:17

The pay-per-use model of the public cloud seemed too good to be true. And you probably quickly caught onto its catch: analyzing and predicting your cloud costs is like driving blindfolded hoping that the street traffic would stay the same. A solid cloud cost management strategy and tooling solves this problem – but only partially. Knowing what your costs are and where your costs come from isn’t going to reduce them magically.

Visualize your Apache Kafka Streams using the Quarkus Dev UI

Aggregated on: 2021-12-11 15:19:17

This article shows how you can visualize Apache Kafka Streams with reactive applications using the Dev UI in Quarkus. Quarkus, a Java framework, provides an extension to utilize the Kafka Streams API and also lets you implement stream processing applications based directly on Kafka. Reactive messaging and Apache Kafka With the rise of event-driven architectures, many developers are adopting reactive programming to write business applications. The requirements for these applications literally specify that they not be processed in real-time because end users don't really expect synchronous communication experiences through web browsers or mobile devices. Instead, low latency is a more important performance criterion, regardless of data volume or concurrent users.

When it got to the point where compiling the project could take more than ten minutes, we decided to see what we could do about it.

Getting Started With Pandas

Aggregated on: 2021-12-10 18:34:16

Today we will introduce one of the first inner training chapters on the fundamentals of DataScience treatment tools. We are talking about Pandas, Numpy, and Matplotlib. Pandas is a third-party library for numerical computing based on NumPy. It excels in handling labeled one-dimensional (1D) data with Series objects and two-dimensional (2D) data with DataFrame objects. NumPy is a third-party library for numerical computing, optimized for working with single- and multi-dimensional arrays. Its primary type is the array type called ndarray. This library contains many routines for statistical analysis.

Microservices Communication With Apache Kafka

Aggregated on: 2021-12-10 18:34:16

When developing a new product, the first thing that comes to mind is how to structure code. There is a battle going on in this regard: monolithic vs microservices. It has been going on for a while because software developers and company owners are still trying to figure out which architectural style is ideal for their applications. The scalability, efficiency, and competitiveness of the product are determined by the strategy used – monolithic vs microservices. While monolithic systems have been used for a while, microservices are a comparatively modern form of software system structure. Indeed, a slew of technologies emerged under the DevOps mindset, allowing us to design scalable, distributed systems based on microservices. One of the main advantages of a microservice architecture is that it makes it simpler to select the technological stack (programming languages, databases, etc.) that is most suited for the desired functionality (service) rather than being forced to take a more conventional, one-size-fits-all approach.

Incidentally, our designer was down with the virus and no member of the team had any design background.

Introduction to Multi-Tenancy in Kubernetes

Aggregated on: 2021-12-10 17:04:16

What Is Multi-Tenancy? The idea of sharing a single instance of an application or of software among various tenants is called multi-tenancy. This approach is quite popular since the rise of cloud environments. Now, with the introduction of Kubernetes, developers and administrators require the same approach to be implemented on Kubernetes clusters. As that would provide better resource utilization, provide better management of underlying compute resources, and reduce cost. This blog post will discuss various available approaches to introduce multi-tenancy in Kubernetes clusters and will try to draw a comparison between all of them.

Ranging from unethical hacking, identity theft, internet scams, social engineering to many more, we hear and see regulations outrightly trying to clamp down all forms of crime and swindling on the internet. However, the stance of the internet law on the legality of web scraping remains controversial. Since you might also find yourself scraping data from the web, either now or in the future, whether for business purposes or personal use, let us address the question: is web scraping legal? You’ll soon find out.

Milvus in IP Protection: Building a Trademark Similarity Search System With Milvus

Aggregated on: 2021-12-10 16:34:16

In recent years, the issue of IP protection has come under the limelight as people's awareness of IP infringement is ever-increasing. Most notably, the multi-national technology giant Apple Inc. has been actively filing lawsuits against various companies for IP infringement, including trademark, patent, and design infringement. Apart from those most notorious cases, Apple Inc. also disputed a trademark application by Woolworths Limited, an Australian supermarket chain, on the grounds of trademark infringement in 2009. Apple. Inc argued that the logo of the Australian brand, a stylized "w", resembles their own logo of an apple. Therefore, Apple Inc. took objection to the range of products, including electronic devices, that Woolworths applied to sell with the logo. The story ends with Woolworths amending its logo and Apple withdrawing its opposition. With the ever-increasing awareness of brand culture, companies are keeping a closer eye on any threats that will harm their intellectual properties (IP) rights. IP infringement includes: Copyright infringement Patent infringement Trademark infringement Design infringement Cybersquatting The aforementioned dispute between Apple and Woolworths is mainly over trademark infringement, precisely the similarity between the trademark images of the two entities. To refrain from becoming another Woolworths, an exhaustive trademark similarity search is a crucial step for applicants both prior to the filing as well as during the review of trademark applications. The most common resort is through a search on the United States Patent and Trademark Office (USPTO) database that contains all of the active and inactive trademark registrations and applications. Despite the not-so-charming UI, this search process is also deeply flawed by its text-based nature as it relies on words and Trademark Design codes (which are hand-annotated labels of design features) to search for images. This article thereby intends to showcase how to build an efficient image-based trademark similarity search system using Milvus, an open-source vector database. A Vector Similarity Search System for Trademarks To build a vector similarity search system for trademarks, you need to go through the following steps: Prepare a massive dataset of logos. Likely, the system can use a dataset like this. Train an image feature extraction model using the dataset and data-driven models or AI algorithms. Convert logos into vectors using the trained model or algorithm in Step 2. Store the vectors and conduct vector similarity searches in Milvus, the open-source vector database. To accelerate the process of feature extraction, you can deploy the trained AI model on multiple servers. However, you do not have to worry about data inconsistency if you use distributed service to process data because you can use Flask to ensure synchronized data processing. When the system is built, your user only needs to upload an image of a logo, and then the system converts this new image into a new vector using the same AI model you trained. The system searches for similar vectors to the new vector in the Milvus database and returns the corresponding vector IDs. Ultimately, your user will be able to see all the results of similar logos to the one he or she has uploaded. The following screenshot is a demonstration of a vector similarity search system for trademarks. As you can see, the user uploaded the logo, the swoosh, of the sportswear brand Nike. The system returns all images that are similar to this logo. In the following sections, let's take a closer look at the two major steps in building a vector similarity search system for trademarks: using AI models for image feature extraction, and using Milvus for vector similarity search. In our case, we used VGG16, a convolutional neural network (CNN), to extract image features and convert them into embedding vectors. Using VGG16 For Image Feature Extraction

Aggregated on: 2021-12-09 20:34:15

DevOps has evolved over the last decade as a combination of practices that combine software development and IT operations. Because of its utility, flexibility, and sophistication, DevOps has become an essential ingredient of success in supporting basic software engineering principles such as CI/CD (continuous integration/continuous deployment) and the exploratory iterations of Agile development. Organizations that follow DevOps practices create a reusable development pipeline and overarching methodology for software development. These frameworks include highly automated workflows that facilitate rapid and repeatable coding efforts, experimentation, test automation, and production-level deployment. New software products can be conceptualized, created, and then stored systematically with archived and auditable data, code versions, documentation, toolchain configurations/dependencies, and scripts. These archives serve purposes such as re-creating original SW development environments, tracking changes, ensuring version reproducibility, and facilitating further enhancement and evolution of software products.

What exactly is a database model? A database model is nothing more than the structure a database developer has chosen to store information. A database model also spells out the relationships between different parts of the dataset, and any limitations that may restrict read or write access. Individual databases are designed based on the rules and concepts of the broader data model the designers adopt. Developers often use these models to strategically design databases for larger-scale real-world projects such as:

General inheritance, whereby a public class is extended over package boundaries, provides a number of challenges and drawbacks and should be avoided in almost all cases. Classes and methods can be made final meaning that subclassing is disallowed which effectively prevents inheritance. While this may sound like a strange thing to do in an object-oriented language like Java, it does carry significant benefits for a large number of class types. But, when should a class or method be final, and just why is general inheritance problematic?

Keystone Interface and Keystone Flag

Aggregated on: 2021-12-08 13:49:15

As we all know, software developers may ease their development process by integrating their work as often as they can. It is also known that releasing frequently into production helps a lot. But developers and project stakeholders don’t want to expose half-developed features to their users. So, what happens in this case? A useful technique to deal with this issue is to build the backend, integrate, but don’t build the user interface. The feature can be integrated and tested, but the UI is held back with the help of a keystone ( more info you may find in Martin Fowler’s blog ) and added only when the feature is completed, showing it to the users.
