Why Is Char Array Preferred Over Strings To Store Passwords in Java?

Aggregated on: Mon Nov 15 2021 10:35:56 GMT+0000 (Coordinated Universal Time)

Although Java developers use both string and character for storing the text data, many people have a hard time choosing one over the other, which is a challenging question to ask. There has been a question which many people ask during a Java interview. But we know that many people prefer a Character array over a string, but they do not know the reason behind it. This post will tell you why people are more inclined to use an array than a string.

Analyzing Code Quality Through LoC

Aggregated on: Mon Nov 15 2021 10:35:56 GMT+0000 (Coordinated Universal Time)

There are several metrics you can deploy to analyze the code size and quality of an application. One of the popular metrics that you can be used is called Lines of Code, also known as LoC. What Does LoC Mean? Lines of Code or LoC is a method used to measure the size of an application by identifying the actual count of Lines of Code it has. For instance, small software projects usually have somewhere between 500 to 5000 Lines of Code, whereas large ones can have thousands or even millions of Lines of Code (LoC).

Fine-Tuning Microsoft’s LayoutLM Model for Invoice Recognition

Image Credit Introduction Building on my recent tutorial on how to annotate PDFs and scanned images for NLP applications, we will attempt to fine-tune the recently released Microsoft’s Layout LM model on an annotated custom dataset that includes French and English invoices. While the previous tutorials focused on using the publicly available FUNSD dataset to fine-tune the model, here we will show the entire process starting from annotation and pre-processing to training and inference.

Java is more like English than you think

Aggregated on: Mon Nov 15 2021 08:20:56 GMT+0000 (Coordinated Universal Time)

At a recent in-house event celebrating the launch of Java 17 I was asked to give a talk on the future of the language. I don’t have a hotline to Oracle, so I took the opportunity to dust off my linguistics degree and point out how the nature and comparatively glacial evolution of human languages is not unlike what you can witness in computer languages, compressed within decades. This is the first of two posts based on that talk. In many ways Java, Perl, Haskell, or Lisp are not at all like human languages. Lines of code only resemble English sentences at a very superficial level. Java is one of many specifications to make a digital machine do your bidding, expressed using a small set of English keywords, special characters, and structural rules to make it easy on the brain of the speaker, i.e., the programmer. Regardless of complexity, the behavior of a program follows unambiguously from its content. Sure, you can bang your head against the wall why it does what it does, but given enough eyeballs, even the worst spaghetti code is deterministic.

Strengthen Muscles of Software Systems

Aggregated on: Mon Nov 15 2021 08:20:56 GMT+0000 (Coordinated Universal Time)

While we understand the need for "Building Software Immunity" and the importance of "Secure Software Engineering Habits", it is equally essential for heavy lifters such as software architects, tech leads, or senior engineers to ensure that the core of the software i.e. architecture or design is strong and maintained robust throughout the lifecycle of the software. Strengthening muscles of software goes far into the software development process, deployment and operations. Typically, it can be achieved via embedding security in business requirements, following design principles, and secure design approaches. Embedding Security in Requirements Incorporating security concerns in the early phases of software development is far easier and cost-effective as many common pitfalls can be avoided that get harder to fix later. There are two approaches that can be taken while defining security requirements:

The Cloud has enabled a lot of new usages that were not possible before. Among them stands Serverless: Serverless computing is a cloud computing execution model in which the cloud provider allocates machine resources on demand, taking care of the servers on behalf of their customers. Serverless computing does not hold resources in volatile memory; computing is rather done in short bursts with the results persisted to storage. When an app is not in use, there are no computing resources allocated to the app.

5 Practical Tips for Successful Business Transformation Programs

Aggregated on: Sun Nov 14 2021 19:20:56 GMT+0000 (Coordinated Universal Time)

The business world has undergone some dramatic changes; a few years back the greatest concern was cybersecurity, but in 2021, the focus shifted to digital transformation. While cybersecurity remains a source of potential danger to their survival, businesses have realized that you must be in the market before you start thinking of breaches and the only thing that can make you remain relevant is to focus on improving customer experience. However, it’s not enough to just say you are embarking on business transformation; the most important thing is how to ensure your business transformation program is successful. The Kotter change model points out that improving the outcomes of business transformation programs relies heavily on the employees who are the ones actually implementing change programs.

Part 2 - How to Hive on GCP using Google DataProc and Cloud Storage

Aggregated on: Sun Nov 14 2021 17:05:56 GMT+0000 (Coordinated Universal Time)

In part 1 of this series, we have seen how to create a Google Dataproc cluster, create external tables in HIVE, point to the data stored on cloud storage, and perform exploratory data analysis in a staging environment. As part of this analysis, we found out that our sample datasets had around: ~ 11% of non-confirming records for Green Taxi Y2019 dataset ~ 33% of non-confirming records for Yellow Taxi Y2019 dataset Identifying non-confirming records is one of the important steps of exploratory data analysis as they can lead to wrong or faulty interpretation of results. So, as part of the next step, we will create a new environment i.e. new external tables in HIVE with only valid data required for deep-dive analysis and eliminate the non-confirming records.

The Mindset of an Impactful Component Team in Agile

Aggregated on: Sun Nov 14 2021 14:50:56 GMT+0000 (Coordinated Universal Time)

Component teams are a reality and they do exist for specific purposes. In the programs I worked on, there were some component teams that worked on specific layers of architecture such as mid-tier validations and generating the PDFs with a click to mirror the screens. They were formed because the intended solutions at these layers required enormous explorations of different tools, open sources, design approaches, etc before these layers could cater to vertical slicing of the application to produce an increment. So essentially these teams had SME’s, Architects, or senior engineers’ part of it for a focused effort on a layered solution which otherwise was not possible to achieve as part of the feature team who primarily focus on the functional increment.

Deploying Serverless NER Transformer Model with AWS Lambda

Get Logged-in User Info in Jakarta EE - The Simplest Way

Aggregated on: Sun Nov 14 2021 14:05:56 GMT+0000 (Coordinated Universal Time)

The security before Java EE 8 / Jakarta EE 8 used to be a bit complicated and confusing. Every specification provided its own way to retrieve information about the logged-in user. The situation greatly improved with the introduction of the Security API that provides a unified way to do that – simply inject the SecurityContext CDI bean. There’s still a small catch – this only works in the servlet context and EJB context. Or, in other words, when processing an HTTP request or inside any type of EJB. The good thing is that this covers most of the cases in which you’ll ever need to retrieve user information. In the other rare cases, you need to use one of the APIs which I also describe in this post.

Becoming a Data-Driven Organization: Hidden Potential and Challenges

Data is a business gold mine for organizations, yet many companies struggle to unlock its complete potential. Through data, organizations can gain a better understanding of their operations and customers. Acting on the data to make informed business decisions is not necessarily a straightforward process. A data-driven organization can glean deep insights from data to update internal processes and respond directly to market feedback and improve their customer relationships. A data-driven organization can also leverage data to identify to create value for their consumers. Statista predicts that by 2022, the big data and analytics market will reach 274 billion dollars. Organizations are playing a vital role in the exponential growth of data by utilizing Big Data technologies for analytics to become data-driven.

Row-Level Security: SQL Server vs Gallium Data

Aggregated on: Sun Nov 14 2021 06:50:56 GMT+0000 (Coordinated Universal Time)

Introduction In SQL Server 2016, Microsoft introduced the concept of row-level security, which gives you fine-grained control over who gets access to what data, potentially down to the level of individual rows. Normally, SQL security grants coarse access to a whole table or view (SQL Server can also do it for columns), and anything more granular than that requires the use of views or stored procedures. There is another way to do row-level security without changing the database clients, and that's with Gallium Data - a free database proxy that can change the network traffic between your database clients and your database servers.

Is Windows 11 Safer Than Windows 10?

Windows 11 is already here. Let's take a look at what Microsoft has changed in terms of security and privacy in its operating system. Does Windows 11 protect users’ data better than Windows 10? How does Windows 11 resist cyberattacks? Windows 11 was released on October 4, 2021. Earlier it produced plenty of hype with its version for testing. Even a simulator was created. I would like to note that this article was prepared before the official release of the new OS version. Some functions could have been changed, removed, or improved as it happened for example, with the minimum system requirements. Initially, Windows 11 was not intended for everyone (at least 8th generation Intel processors were required). However, the Windows community found a way to bypass the installation lock. Microsoft decided that it would not take action to restrict installations. In its blog, the corporation disowned possible problems, including problems with drivers on old PCs.

Understanding MongoDB and NoSQL Database

Aggregated on: Sat Nov 13 2021 08:35:55 GMT+0000 (Coordinated Universal Time)

NoSQL data sets arose in the latter part of the 2000s as the expense of storage drastically diminished. The days of expecting to create a complicated, hard to-oversee data model to avoid data replication were long gone and the primary expense of programming and development was now focused on the developers themselves, and hence NoSQL databases were brought into the picture to enhance their productivity. As storage costs quickly diminished, the measure of data that applications expected to store increased, and the query expanded as well. This data was received in all shapes and sizes — organized, semi-organized, and polymorphic — and characterizing the schema ahead of time turned out to be almost incomprehensible. NoSQL databases permitted the developers to store colossal measures of unstructured data, providing them with a ton of flexibility.

A Quick Word on Hybrid AI in Natural Language Processing

Aggregated on: Sat Nov 13 2021 07:35:55 GMT+0000 (Coordinated Universal Time)

Any solution aimed at processing unstructured data (i.e., language, specifically text in most cases) is today based on one of two main approaches: Machine Learning and Symbolic. Both can be delivered in multiple ways (different algorithms in the case of ML, from shallow linguistics to semantic technology in the case of Symbolic), but not much has been done so far in the realm of hybrid approaches. While choosing one over the other is always going to present a compromise between advantages and drawbacks (higher accuracy coming from Symbolic, more flexibility derived from ML), Hybrid AI — or Hybrid NL — is a revolutionary path to solve linguistic challenges that can leverage the best of both worlds and, ultimately, make your NLP practices graduate to NLU (Natural Language Understanding). I won’t spend time explaining how ML or Symbolic work since there’s a ton of literature about that already, I’ll focus this page on Hybrid instead. What is Going Hybrid? To frame this conversation in a practical fashion, we must look at two aspects: development, and workflow. At the development stage, going hybrid means that a Symbolic solution will support the creation of a Machine Learning model in order to either reduce the effort or enhance its quality. On the other hand, at the production stage, our workflow can be supported by both ML and Symbolic to deliver a more precise outcome. In a project that considers the Machine Learning piece the pivot of the solution, the first type of integration places Symbolic at the top (before even creating a Machine Learning model), and the second one at the bottom (curating or enhancing the final output). Naturally, both of these hybrid ways can be present at the same time in a linguistic project.

Fast Spring Boot AWS Lambdas with GraalVM

Aggregated on: Sat Nov 13 2021 06:05:55 GMT+0000 (Coordinated Universal Time)

In my previous blog post, I documented how to take a Java Spring Boot application and convert it into a serverless function, which can be run in AWS Lambda. Anyone who's done this before knows that cold starts are a big downside - Java and Spring Boot are not known for their speedy startup times, and a typical full fat Spring Boot-converted lambda can take anything from 10 to 90 seconds depending on how much memory and CPU you allocate it. This may force you to over-provision them to compensate for the cold starts, but that's a pretty expensive sledgehammer. There is always provisioned concurrency, but that doesn't work out much cheaper either (and negates the responsive scalability of lambda as you have to anticipate how many you'll need in advance).

The frequency of attacks is up year over a year along with the diversity of business types being attacked. In the same report, you can see details of various organizations being attacked. Couple this with Cybersecurity Talent Crunch to Create 350 Million Unfilled Jobs Globally by 2021, and it is apparent that many companies will have to rely on existing worker talent to combat an ever-increasing threat. Of course, high-tech companies have high-tech talent, but what about all the other types of organizations like government, education, service industry, and manufacturing. We all like to think we have skilled workers regardless of our industry. Still, under this new growing threat, our current in-house cybersecurity skills might not be at the level needed to provide maximum safeguard.

How to Start Cloud Application Development

Cloud application development is a necessity in a modern enterprise world. You can hardly find a company that has never used a cloud-based application or any of the SaaS products. Cloud applications are now dominating the market over desktop software for various reasons. The main advantage is they can be accessed at any time from anywhere with any device that has a web browser. Besides, when a company develops a cloud application, it automatically means that all users are working with the same version of the app. This greatly reduces the time and resources required for new features introduction, security updates, and synchronization. We will look at the advantages of cloud application development later in the article.

One of the priority areas for PVS-Studio development is to cover categories from the OWASP Top Ten 2017 in the C# analyzer. We also plan to cover the Top Ten 2021 in the future. The most unusual for us is the A9:2017 category: Using Components with Known Vulnerabilities. This category has the A6 position in the preliminary version of OWASP 2021. The rule implementation for this category is an important task for our analyzer. It allows us to classify PVS-Studio as an SCA (Software Composition Analysis) tool. Which approach to implementation should we choose? Let's figure it out! Using Components With Known Vulnerabilities The A9 threat category (which turned into A6 in the preliminary OWASP 2021 version) is dedicated to using components with known vulnerabilities. These are the components that have the corresponding entries in the CVE database. CVE (Common Vulnerabilities and Exposures) is a database of records about real-life vulnerabilities in software, hardware, service components, etc.

Microsoft Cloud for Healthcare: Architect Perspective

Aggregated on: Fri Nov 12 2021 22:20:55 GMT+0000 (Coordinated Universal Time)

The COVID-19 pandemic has impacted not just every aspect of people’s lives but every aspect of the healthcare system. It’s preventing healthcare delivery practices from operating at normal business levels, disrupting patient access to high-quality medical care, and forcing everyone to think about how to continue pushing forward in new and different ways. As a result of the pandemic, the healthcare industry has seen a massive transformation. In this post-digital world, healthcare occupies a unique position. The industry has realized that digital must be integrated into all aspects of its operations since there is no longer any distinction between digital and non-digital media. Moreover, consumers are now driving the change in healthcare. There has been a massive shift in their needs. People increasingly demand healthcare on their terms, from leveraging data to identify their meal preferences to getting those meals exactly when they want them, to even delivering information to the proper channels. Digital can now support healthcare delivery based on preferences to patients — when, how, and where they want it.

Global Tables vs Duplicate Indexes

Aggregated on: Fri Nov 12 2021 19:35:55 GMT+0000 (Coordinated Universal Time)

With CockroachDB version 21.1, a new concept of “global tables” was introduced. This functionality is a good fit for situations where read latency on a table needs to be very low and write latency can be much higher than normal [read: it needs to be fast when doing lookups, but we can tolerate lengthy writes]. It is also a fit for when reads must be up to date for business reasons or because the table is referenced by foreign keys or where latency-critical reads cannot be tied to specific regions. So using the global tables functionality is ideal for any kind of reference table, where we want to get the data out very quickly, but we can handle long inserts and updates. With global tables, the lengthy writes go about doing all the pre-work to prevent any contention and serializable errors that we would traditionally see. When we read from the table, all the work has previously been done to avoid any contention and we can access the closest replica and read from it, effectively as if we were doing a follower read but in real time.

The online ecosystem is designed to be open for live interactions. Online users can indulge in immersive web pages, engage in social conversations, and post online reviews. Web platforms are built to encourage users to post opinions without restrictions. This has stretched the scope for building several meaningful digital experiences in the web ecosystem. Online products and services get positive and, every now and then, negative reviews. A fair amount of scrutinizing behavior by users can be spotted on most online platforms. Heaps of reviews are posted online by users on marketplaces, community web pages, and social media pages. The growing volume of user review data, especially that causes damage to a company’s online reputation, requires efficient management.
