Alternatives to Handsontable and ag-Grid

Aggregated on: 2023-01-13 14:14:20

In any industry, big brand names certainly affect the customer purchase decision, and web development is not an exception. As a vivid example, we can mention such an important aspect of any business app as data management. A web developer who needs a proper JavaScript library for this purpose may be tempted to choose time-tested ag-Grid and Handsontable components and save themselves the trouble of the time-consuming search. These tools are really useful for implementing JavaScript data tables and spreadsheets. But why limit yourself to only a couple of trendy products when there are so many alternatives on the market? In this article, I’ve put together JavaScript tools from well-known vendors that can be used instead of Handsontable and ag-Grid for integrating both grids and spreadsheets (as well as other useful functionalities such as a pivot table) into web apps based on popular frameworks.

AWS Fargate: Deploying Jakarta EE Applications on Serverless Infrastructures

Aggregated on: 2023-01-13 04:44:19

Jakarta EE is a unanimously adopted and probably the most popular Java enterprise-grade software development framework. With the industry-wide adoption of microservices-based architectures, its popularity is skyrocketing and during these last years, it has become the preferred framework for professional software enterprise applications and services development in Java. Jakarta EE applications used to traditionally be deployed in run-times or application servers like Wildfly, GlassFish, Payara, JBoss EAP, WebLogic, WebSphere, and others, which might have been criticized for their apparent heaviness and expansive costs. With the advent and the ubiquitousness of the cloud, these constraints are going to become less restrictive, especially thanks to the serverless technology, which provides increased flexibility, for standard low costs.

Expedia Group™️ acts as a booking agent for all sorts of travel. An issue we’ve wrestled with is when a hotel (or vacation rental, activity, etc.) shares public contact information through our platform that allows for direct booking. This act violates our service agreements, and we must detect if it happens. Furthermore, this mechanism needs to scale to review an ongoing stream of data generated by bookings, website updates, client updates, etc. This is not a unique problem in the travel industry. It can be generalized to verify a whole class of financial and legal agreements on an ongoing basis. Speed is of the essence; quickly detecting violations protects the platform’s viability and stops possible fraud.

Using AI and Machine Learning To Create Software

Aggregated on: 2023-01-12 18:29:19

I've just released a new version of Aista Magic Cloud that allows you to use natural language to create Hyperlambda backend code, and its accuracy is at 90% after only two days of experimenting with the thing. To appreciate this feat, I suggest you watch the following YouTube video. The way it works is that you start out with a base model. I found Curie to give me the best result. Then you supply OpenAI's API with a bunch of questions and answers. This is the most critical part since the better your questions and answers are, the better your end result will become. I found that extrapolating my questions with variables allowed the model to be able to recognize variables, and substitute these, composing larger blocks of code from smaller blocks more naturally. An example of the above could be, for instance, the following questions, with code snippets solving your questions.

API Security Is Finally Gaining Attention That it Deserves

Aggregated on: 2023-01-12 14:44:19

What Is API? An API, or Application Programming Interface, is a set of rules and protocols that allows different software applications to communicate with each other. It defines how software components should interact, and APIs act as the "middleman" between different systems or applications. APIs allow different systems to share data and functionality. For example, a website might use an API to access the functionality of a third-party service, such as a payment gateway or a weather service. Or, a mobile app might use an API to access a back-end system or database. This allows the developer to create a more powerful and flexible system by using pre-existing building blocks rather than having to create everything from scratch.

The Journey to Becoming a Rockstar Salesforce Developer

Aggregated on: 2023-01-12 12:14:19

The IDC projects that 4.2M new Salesforce-related jobs will be created between 2019 and 2024. A portion of these roles are Salesforce developer positions. But what’s the job of a Salesforce developer, and how do professionals transition into these roles? These questions– and workforce evolutions– are close to my personal experience. I had a conversation with Alba Rivas to discuss these topics, as they’re part of her journey as well. In this post, we’ll discuss her history with the platform, and she’ll outline what a Salesforce developer job looks like today. Alba will also give you tips and tricks to successfully get started yourself. Alba began her path to Salesforce by studying telecommunications engineering, and she’s been developing software since she graduated. Early in her career, she worked on applications primarily built with Python and Java. But in 2014, Alba was contacted by a company who built apps on the Salesforce platform to sell through Salesforce’s app marketplace, AppExchange. The company was looking for back-end developers. The native back-end language used in Salesforce is Apex, an object-oriented domain-specific language similar to Java or C++. Because there weren’t many Salesforce developers in the market yet, the company was looking for developers with object-oriented programming skills. Alba told me that initially, she was reluctant to take the job. She was skeptical of a platform that had created its own programming languages. Ultimately, Alba finally decided to accept the offer and give it a chance.

Project Loom And Kotlin: Some Experiments

Aggregated on: 2023-01-12 00:44:19

The publishing of Java 19 in September 2022 heralded the first public release of the much-awaited Project Loom into the JVM (Java Virtual Machine) ecosystem. A brief description for those who are unaware: Project Loom is an endeavor year in the making by the developers of the Java programming language to enable the use of virtual threads within Java code. Virtual threads are named as such because, although they possess the appearance and behavior of what developers traditionally regard as threads, they are not actual OS (operating system) threads and instead are aggregated together and executed on top of such OS threads. The primary benefit of this is that OS threads are “heavy” and bound to a relatively-small limit before their memory requirements overwhelm the operating system, whereas virtual threads are “lightweight” and can be used in much higher numbers. While the functionality of Project Loom is still in the preview phase in the Java 19 release—and “full” functionality is not forthcoming until at least the release of Java 21 in 2023 (or even further in the future)—excitement for Project Loom is quite high, and there is already movement underway in major Java ecosystems to accommodate virtual threads to their utmost potential.

What Is Azure Content Delivery Network Service?

Aggregated on: 2023-01-11 19:44:19

A distributed network of servers known as the Azure CDN is used to cache and store material so that it may be viewed by computers all over the world. Geographical separation between a website visitor and the server that hosts the site can significantly increase latency. With the goal of reducing latency, Azure CDN servers are situated close to end users. Azure CDN allows a client seeking that content to obtain it from the location to which they have the lowest latency and maximum bandwidth connection rather than retrieving it from a single site that may be on another continent or in another hemisphere. Point-of-presence (POP) locations are the server locations that house content repositories. By utilizing various network optimizations with CDN POPs, such as route optimization to avoid Border Gateway Protocol (BGP), Azure CDN may also speed up dynamic material that cannot be cached.

Is Your Data Infrastructure Stifling Innovation?

Aggregated on: 2023-01-11 18:14:19

There are myriad reasons why an estimated 90% of startups fail. You need a great idea (and not just one great idea); you need inspiration, funding, smart people — and a fair amount of luck. Miss any one of these factors, and failure might be a foregone conclusion. For young companies or small teams that build applications, data can be another stumbling block. The databases they rely on have historically stymied innovation by being complex and costly to spin up, manage, and maintain. Proofs of concept — ideas with the potential to turn into something big — can die before even being tested due to a lack of funding or database capacity.

Google AppSheet Tutorial for Non-Technical Citizen Developers

Aggregated on: 2023-01-11 16:14:19

AppSheet is a no-code framework offered by Google, which is to say it’s a technology that allows people who aren’t software developers — but rather specialists in other fields — to seamlessly build professional web applications. The important thing here is that the app creators don’t have to write code (hence the term “no-code”). This idea is called Citizen Development, and it has gained popularity in recent years. Google AppSheet replaced the old Google App Maker. It’s worth noting that it’s a part of Google Workspace — which means that the applications you create can leverage other areas of the Google ecosystem (such as the popular Google Cloud Platform). The assumption here is very simple: if the organization has implemented the Google Workspace package, then its employees should be able to build a fully functional application for an internal or external user — based on AppSheet — which directly draws from the data processed in the company. Is this assumption true? Let’s find out how functional and complex AppSheet web apps can really be.

Enterprise Cloud Computing Adoption: Benefits and Challenges

Aggregated on: 2023-01-11 13:14:19

Cloud computing is an internet-based infrastructure that allows users to access computing resources on demand from any location. It is a new way of delivering computing resources rather than modern technology. Some examples of non-healthcare applications of cloud computing include Google, Gmail, Docs, and Microsoft Hotmail, while some healthcare examples include the Google Health platform and Microsoft HealthVault. This model has several advantages over traditional computing, including the ability to pay for use on a short-term basis as needed, the lack of a required upfront commitment from users, and the availability of enormous amounts of computing resources on demand. Cloud computing has become popular in recent years due to its advancements. It is a way of providing computing and storage resources on demand, with the goal of reducing costs for businesses. Cloud storage, a key component of cloud computing, allows users to store and access data over the internet and offers benefits such as offsite backup, security, and large storage capacity at a low cost. There are five types of cloud storage: private, personal, public, community, and hybrid.

The Real Democratization of AI, and Why It Has to Be Closely Monitored

Aggregated on: 2023-01-11 03:14:18

In recent years, the topic of AI democratization has gained a lot of attention. But what does it really mean, and why is it important? And most importantly, how can we make sure that the democratization of AI is safe and responsible? In this article, we'll explore the concept of AI democratization, how it has evolved, and why it's crucial to closely monitor and manage its use to ensure that it is safe and responsible. What AI Democratization Used to Be In the past, AI democratization was primarily associated with "Auto ML" companies and tools. These promised to allow anyone, regardless of their technical knowledge, to build their own AI models. While this may have seemed like a democratization of AI, the reality was that these tools often resulted in mediocre results at best. Most companies realized that to truly derive value from AI, they needed teams of knowledgeable professionals who understood how to build and optimize models.

How To Develop a QR Code Scanner for Pay Parking

Aggregated on: 2023-01-11 00:14:18

Background Many weeks ago, when I tried to exit a parking lot, I was—once again—battling with technology as I tried to pay the parking fee. I opened an app and used it to scan the QR payment code on the wall, but it just wouldn’t recognize the code because it was too far away. Thankfully, a parking lot attendant came out to help me complete the payment, sparing me from the embarrassment of the cars behind me beeping their horns in frustration. This made me want to create a QR code scanning app that could save me from such future pain. The first demo app I created was, truth to be told, a failure. First, the distance between my phone and a QR code had to be within 30 cm, otherwise the app would fail to recognize the code. However, in most cases, this distance is not ideal for a parking lot.

Aggregated on: 2023-01-10 23:14:18

Modern data architecture has largely shifted away from the ETL (Extract-Transform-Load) paradigm to the ELT (Extract-Load-Transform) paradigm where raw data is first loaded into a data lake before transformations are applied (e.g., aggregations, joins) for further analysis. Traditional ETL pipelines were hard to maintain and relatively inflexible with changing business needs. As new cloud technologies promised cheaper storage and better scalability, data pipelines could move away from pre-built extractions and batch uploads to a more streaming architecture. Change data capture (CDC) fits nicely into this paradigm shift where changes to data from one source can be streamed to other destinations. As the name implies, CDC tracks changes in data (usually a database) and provides plugins to act on those changes. For event-driven architectures, CDC is especially useful as a consistent data delivery mechanism between service boundaries (e.g., Outbox Pattern). In a complex microservice environment, CDC helps to simplify data delivery logic by offloading the burden to the CDC systems.

Installing or Upgrading to Fedora 37 on MacBook Pro 13-Inch (Late 2011)

Aggregated on: 2023-01-10 21:29:18

This weekend I decided to update my old MacBook Pro 13 inch from late 2011, with 125GB SSD and 8GB RAM. It's a machine I've taken on trips around the world and back in the day ran many a session, workshop, or demo on sharing all that developer goodness. Last time we checked, this was installed using Fedora 36, so how about an update to Fedora 37?

Understanding Database Indexes

Aggregated on: 2023-01-10 20:14:18

Although it can be challenging to choose which type to use, database indexes are necessary for enhancing query efficiency. We'll discuss the various database index types, their benefits and drawbacks, and when to utilize each one in this blog post. Read on to discover more about database indexing and how it might benefit your company. What Is a Database Index? A database index is a data structure that improves the speed of data retrieval operations on a database table. Essentially, it is like an index in the back of a textbook that provides quick access to specific information, allowing for faster searches of data. It can be used to facilitate faster sorting and retrieval of records from a table by providing an alternative path to access the data. Indexes can significantly improve the performance of SELECT queries, but they also slow down INSERT, UPDATE, and DELETE operations. Creating the right indexes in a database can optimize query performance, providing your system with a great advantage over other applications.

Apache Avro to ORC Using Apache Gobblin

Apache Avro and Apache ORC Apache Avro and Apache ORC (Optimized Row Columnar) are top-level projects under the Apache Software Foundation. Fundamentally, they are data serialization formats with different strengths. Apache Avro is an efficient row-based binary file format for serializing data during transfer or at rest. It uses a schema to define the data structure that has to be serialized, and the schema is collocated and stored as part of Avro’s data file. As frequently needed in big data space, Avro was designed to support data evolution by allowing the augmentation of new fields to the data structure without the need for a complete recompilation of the code that uses it.

Application Assessment Questions for Migration Projects

Aggregated on: 2023-01-10 19:14:18

Most existing applications/projects are moving to Cloud platforms/On-premise using microservices architectures. Assessment of the existing application is critical concerning application complexity and risk. An appropriate strategy has to define to analyze the current application to determine the risk and complexity of the existing application landscape. The assessment considers factors like Overall Architecture, Presentation Layer, Business Layer, Data Layer, Security, Deployment, Technology, Infrastructure, Performance, and Monitoring for existing applications. Collect the information from the different parameters and decide which is the best option for Migration strategies like Rehost, Refactor, Rearchitect, and Rebuild. For each parameter, the architect fills in the information by studying the existing application/collecting the information from the application stack holders. Application assessment helps the Organization to understand the following: Understanding of the existing application architecture and critical findings. Integration points across applications (upstream and downstream). Infrastructure, Software usage Pain areas related to Business users. Road map to target system platform using any one of the migration strategies. There are a number of assessment criteria that information will need to be gathered for to provide an assessment of the applications as below:
