Cybersecurity Threats of EV Charging Stations

Aggregated on: 2022-05-18 18:20:55

According to Statista, In January 2022, there were almost 113,600 charging stations for electric vehicles in the United States. California has a large number of these charging stations, with nearly 41,300 public and private power outlets. As the number of electric vehicles (EVs) on the road continues to grow, so does the need for public and private EV charging stations. While most EV owners charge their cars at home or work, there are still many times when they need to rely on public charging stations.

The more the counter next to my years-in-tech metric increments upward, the more I find myself in situations where I talk about career paths, skill decisions, and choices about specializations. It might be talking to a publication, on a panel, or one-on-one with someone who wants to get into or ahead in IT. One of the questions that come up a lot is something like, "Are we at the point where everyone in IT needs to learn to code?"

Debugging the Java Message Service (JMS) API Using Lightrun

Aggregated on: 2022-05-18 17:50:55

The Java Message Service API (JMS) was developed by Sun Microsystems in the days of Java EE. The JMS API provides us with simple messaging abstractions, including message producer, message consumer, and so on. Messaging APIs let us place a message on a “queue” and consume messages placed into said queue. This is immensely useful for high-throughput systems — instead of wasting user time by performing a slow operation in real time, an enterprise application can send a message. This non-blocking approach enables extremely high throughput while maintaining reliability at scale. The message carries a transactional context which provides some guarantees on deliverability and reliability. As a result, we can post a message in a method and then just return, which provides similar guarantees to the ones we have when writing to an ACID database.

Why to Implement GitOps into Your Kubernetes CI/CD Pipelines

Aggregated on: 2022-05-18 17:50:55

Continuous integration and continuous delivery have become essential to meet the demands of the modern software development process. CI/CD pipelines are popular within software delivery pipelines for facilitating software development and deployment tasks. However, infrastructure management is often tracked outside of CI/CD. Most of the time, infrastructure and configurations are managed outside the CI/CD pipeline, even for applications requiring rapid infrastructure modifications or configuration changes like in a containerized environment with Kubernetes. In this post, we will explore the need to implement GitOps within your Kubernetes CI/CD pipelines.

Data Collection: Methods, Definition, Types, and Tools

Aggregated on: 2022-05-18 17:20:55

Access to information gives a unique opportunity to understand the interests and demands of the customers much better and even exceed their expectations. So naturally, this makes data collection urgent, the first and most crucial step of any decision-making process. But before diving deeper into the topic, let’s get started with some essential definitions. What Is Data Collection? Data collection is gathering data; it's further measuring, processing, assessing, and analyzing for research purposes. It’s conducted with the help of established, validated techniques, which make it possible to answer research questions, test hypotheses, and evaluate final results. The main goal of data collection is to get access to reliable sources of information that will provide data for further analysis and make data-driven decisions possible.

Performing ETL with AWS Glue Interactive Sessions

Aggregated on: 2022-05-17 21:50:55

If you have been using AWS Glue lately, you might have witnessed the complexity of setting up the infrastructure for building, testing and running a Glue job using Glue Dev endpoint. Setting up a Dev endpoint is no easy task as it takes a lot of effort to be done on your local machine. By using interactive sessions, you can not only author a job faster than ever but also make the whole process easier for you. Drawbacks of Using Glue Dev Endpoint Cost: When you want to author a lot of jobs, the dev endpoint can be of great help but if you want to build and run only a few jobs it will turn out to be a costly investment. Since a dev endpoint is an EC2 machine backed with the Glue libraries, cost turns out to be a major factor in using the dev endpoint for just a handful of jobs. Moreover, the minimum billing duration for each provisioned dev endpoint is 10 minutes, which does not make it a great choice for running a single job that takes about 2-3 minutes to complete. Complexity: Setting up a dev endpoint is a complex task. It requires the stuff to be downloaded on your local machine which makes it difficult for the systems protected with a firewall or the systems without admin rights. Time: Timing is another drawback of using the Dev endpoint for a less number of jobs. Suppose you want to author 2 PySpark ETL jobs that take a minute each to run. Now, provisioning and establishing a dev endpoint and transferring files to the dev endpoint will take a lot more time to complete than completing the jobs themselves. Flexibility: Once a dev endpoint has been provisioned the billing continues until you manually delete the dev endpoint. Also note, that AWS continues to charge you till the dev endpoint is in a READY state. Solution - Interactive Session An interactive session allows you to leverage the simplicity of Jupyter notebooks while authoring the complex glue jobs interactively. So, let us deep dive into setting up our own interactive session.

Why Is SQL Knowledge Vital for Data Scientists? A Sneak Peek

Aggregated on: 2022-05-17 20:20:54

Businesses succeed when making informed judgments based on current technology and market trends, rivals, and partners. Extracting data from databases using the Structured Query Language (SQL, pronounced "sequel") is one of the most common methods firms get business intelligence to assist them in making those decisions. According to Oracle Patches, SQL dates back to the early relational databases built in the 1970s by Dr. Edgar Codd, Donald Chamberlin, Raymond Boyce, and other IBM researchers. Data in one table in a relational database can be linked to data in any of the tables in the database's thousands or even millions of entries. As a result, SQL makes searching for and retrieving data on business-related issues and presenting the findings in a report easier and quicker than ever.

SDLC Vs STLC: What's the Difference?

Aggregated on: 2022-05-17 18:50:54

What Is STLC? STLC stands for software testing life cycle, and it consists of several phases that must be completed in order to test software applications. STLC consists of several phases that are used to test software programs and guarantee that they meet user requirements. STLC Phases Are as Below: Requirement Analysis Test Planning Test Case Development Test Case Execution Test Closure 1) Requirement Analysis: One of the most significant phases of the STLC is requirement analysis, in which the task owner will connect with multiple stakeholders (clients, business analysts, technical leads, and system architects, among others) to determine the requirements. The testing team analyses the requirements from a testing standpoint to find the testable requirements during the Requirement analysis phase.

Unit Vs Integration Testing: What's the Difference?

Aggregated on: 2022-05-17 18:20:54

What Is Unit Testing? Unit testing entails testing each unit or an individual component of the product application. The goal of unit testing is to approve unit parts as they are executed. A unit is a single testable component of a product framework tested during the application programming development process. The goal of unit testing is to ensure the accuracy of segregated code. A unit segment is an application's individual capability or code.

What Powers Similarity Search in Milvus Vector Database

Aggregated on: 2022-05-17 17:50:54

As the core vector execution engine, Knowhere to Milvus is what an engine is to a sports car. This post introduces what Knowhere is, how it is different from Faiss, and how the code of Knowhere is structured. The Concept of Knowhere Narrowly speaking, Knowhere is an operation interface for accessing services in the upper layers of the system and vector similarity search libraries like Faiss, Hnswlib and Annoy in the lower layers of the system. In addition, Knowhere is also in charge of heterogeneous computing. More specifically, Knowhere controls which hardware (eg. CPU or GPU) to execute index building and search requests. This is how Knowhere gets its name — knowing where to execute the operations. More types of hardware including DPU and TPU will be supported in future releases.

The Three Must-Haves for Machine Learning Monitoring

Aggregated on: 2022-05-17 16:50:54

Machine learning models are not static pieces of code but, instead, dynamic predictors that depend on data, hyperparameters, evaluation metrics, and many other variables; it is vital to have insight into the training and deployment process to prevent model drift predictive stasis. That said, not all monitoring solutions are created equal. These are the three must-haves for a machine learning monitoring tool, whether you decide to build or buy a solution. Complete Process Visibility Many applications involve multiple models working in tandem, and these models serve a higher business purpose which may be two or three steps downstream. Furthermore, the model's behavior will likely be dependent on data transformations that are multiple steps upstream. Thus, a simple monitoring system that focuses on single model behavior will not capture the holistic picture of model performance related to the global business context. More profound knowledge of model viability only comes from complete process visibility – having insight into the entire data flow, metadata, context, and overarching business processes on which the modeling is predicated. For example, as part of a credit approval application, a bank may deploy a suite of models that assess creditworthiness, screen for potential fraud, and dynamically allocate trending offers and promos. A simple monitoring system might be able to evaluate any one of these models individually, but solving the overall business problem demands an understanding of the interlocution between them. While they may have divergent modeling goals, each model rests upon a shared foundation of training data, context, and business metadata. Thus, an effective monitoring solution will take these disparate pieces into account and generate unified insights that harness this shared information. These might include identifying a niche and underutilized customer segments in the training data distribution, flagging potential instances of concept and data drift, understanding the aggregate model impact on business KPIs, and more. The best monitoring solutions can also work not only on ML models but also on generic, tabularized data, allowing the monitoring solution to be extended to all business use-cases, not just those involving an ML component.

Java: Why Core-to-Core Latency Matters

Aggregated on: 2022-05-17 16:50:54

Last year we had a global shortage of microchips; today, I feel there is a worldwide shortage of software developers. Like many other software companies, Chronicle Software is rapidly expanding and interviewing candidates. We usually ask candidates to demonstrate a good knowledge of core Java, and then we cover slightly more advanced concepts, such as the use of volatile memory, memory barriers, and fences. While it is important to have a high-level understanding of these concepts when writing concurrent code, it's surprising how few Java developers with 10+ years of experience have a deep knowledge of the underlying hardware. An initial goal of Java was to “write once, run anywhere,” but does that mean we should not be sympathetic to the hardware? Java has done an excellent job at shielding developers from their platform; it is not unreasonable that most developers would rather solve their business problems than become overly burdened with the internal workings of their silicon. However, some sectors, such as fintech, benefit from fast software with predictable latencies, where every last microsecond can make a massive difference to their bottom line. For these sectors, it can be beneficial to have a reasonable grasp of the underlying hardware and basic knowledge of the areas described in the following sections.

Password Authentication. How to Correctly Do It.

Aggregated on: 2022-05-16 21:35:54

The problem of cybersecurity is quite severe nowadays. Even large and well-known companies face the problem of sensitive user data leakage. It can be unauthorized access to databases, leaked logs, etc. Quite often, we encounter day 0 vulnerabilities that attackers can exploit. All this negatively affects the security of users themselves and the business's reputation. In this article, I would like to explain how to implement storing user authentication data with password authentication. Authentication Authentication is the process of confirming by the user that he is the owner of the presented identifier. The most apparent and most familiar authentication process is password authentication. The user goes to the login page, enters his username/password, and logs on. In this article, I will show how you can implement authentication on the server.

How To Create PR Review Apps With Render

Aggregated on: 2022-05-16 21:05:54

Dungeon crawler demo app Code reviews are essential before merging a pull request. It’s a common practice to have another engineer look through the code changes, and it’s even better if you have a continuous integration (CI) pipeline configured that runs linters and unit tests to catch issues automatically. For UI changes, it’s also a great idea to visually inspect the changes in the app. Doing so may require the reviewer to check out the branch and run the app on their machine. Depending on the complexity of your app’s architecture, running the app locally may be trivial to do with a single command, or it may require several steps and a fair amount of time. Pull request review apps help facilitate this process by deploying a version of the app with the pull request’s changes applied in a preview environment. Now the reviewer doesn’t need to pull down the code themselves!

Why Performance Projects Fail?

Aggregated on: 2022-05-16 20:35:54

Projects involving performance testing and engineering fail for a variety of reasons. The majority of performance project failures occur for various highly complex reasons from every phase of the development life cycle and performance testing life cycle. Sometimes, performance problems are uncontrollable, and it’s out of the control of a project manager, technical architects, or performance engineers. In my experience, from both business and personal levels, most the performance projects fail due to simply a lack of communication between performance engineers, developers, DBA's, business teams, and stakeholders from the beginning, and this ends up causing many other problems which will directly impact application performance and ROI. The only objective of strategic, effective performance testing for any application/product is to achieve a satisfactory return on investment. Performance testing and engineering the applications are risky and always require a lot of trial and error with rigorous testing from the early stages of development. Failures in performance testing projects must be treated similarly to other business problems. It is essential to understand what went wrong, why it went wrong, and what can be done to prevent it. In most scenarios, the performance engineers have to run the one-man show role to make everyone educate/understand the performance challenges in the end-to-end full life cycle implementations. Working with Practice and COE teams, we continued seeing the same mistakes repeatedly from multiple teams and projects, so, based on my personal experience, I have compiled a list of reasons Why Performance Projects Fail.

Testing Under the Hood Or Behind the Wheel

Aggregated on: 2022-05-16 20:05:54

In a room full of architects, no two will agree about their exact job description, as the joke goes. In a similar vein, someone in our team had a refreshing solution to another persistent bone of contention: how do you define an integration test? Don’t try to reconcile differing opinions and just stop using the term altogether. I liked it very much. Rather than think of unit and integration tests, it’s more helpful to distinguish between tests that validate code versus ones that validate public interfaces and recognize that within each category the scope varies for each individual test. Here's the first confusion that the word ‘integration’ throws up. Is it the integrated parts we target, or their points of integration? The first approach checks that parts cooperate and fulfill (part of) the implementation of some business functionality, for example submitting a new order and making sure that it is validated and saved. The latter category is only about checking contracts. What exact messages do we expect component A to receive and how should it react? Older readers may be reminded of WSDL and XML Schema. Not popular anymore, but still around in many enterprises.
