Real-Time Edge Application With Apache Pulsar

Aggregated on: 2021-12-18 15:34:21

The explosive growth of connected remote devices is posing challenges for the centralized computing paradigm. Due to network and infrastructure limitations, organizations find it increasingly difficult to move and process all the device-generated data in data centers or the cloud without latency or performance issues. As a result, edge applications are on the rise. By Gartner’s estimation, 75% of enterprise data will be created and processed outside data centers or the cloud by 2025. So what are edge applications? Edge applications run on or near the sources of data, such as IoT devices and local edge servers, and edge execution. Edge computing enables computation, storage, cache, management, alerting, machine learning, and routing to happen beyond data centers and the cloud. Organizations across industries, such as retail, farming, manufacturing, transportation, healthcare, and telecommunications, are adopting edge applications to achieve lower latency, better bandwidth availability, lower infrastructure costs, and faster decision-making.

How COVID Changed the Way We Work With SQL

Aggregated on: 2021-12-18 13:04:21

Life was normal until 2020's monstrously bad news - Covid - came around. Developers got out of bed, then marched to the office to crunch code as they always do. While inside of the office, they reviewed their goals, played with Git, interacted with their colleagues over a cup (or two) of coffee, and built products relevant to the functionality of the company. Many developers also had side-projects that they would go home and work on during their free time as their hobby. While in the office, developers would be busy regurgitating code - web developers, for example, would work with PHP, SQL, CSS, Javascript, and its libraries (say, jQuery). Meanwhile, database administrators would think deeply about the performance of their database instances (they would take care of indexing and normalizing their data, or work with big data sets, etc.). Once the code was complete, they'd document it and push it over to GitHub.

A Site Reliability Engineer’s Guide to the Holiday Season

Aggregated on: 2021-12-18 09:19:21

It’s almost a cliché to say you have a love/hate relationship with the holiday season. But if you’re an SRE, you may have better reasons than the rest of humanity to hate the end-of-year holidays in particular. Indeed, even if you like the holidays themselves, the fact that reliability issues tend to peak during the holiday period is reason enough for SREs to be less than perfectly cheerful at this time of year.

Sacrificial Architecture: Case Studies

Aggregated on: 2021-12-18 00:49:21

One of the toughest decisions your software development team may face as you scale is deciding between keeping your current codebase and rebuilding on new software architecture. In this article, we will see what so-called sacrificial architecture is and why sometimes it's better to build something from scratch instead of trying to continue and improve what already exists. Rethink, Restructure, and Rebuild Sometimes it takes less effort in terms of time and money to build a solution from scratch. The key here is to rethink, restructure and rebuild. Of course, it may bring a bit of frustration that the previous work "goes to the rubbish bin", but in reality this know-know that you got, these lessons that you learned to lead you to develop a much more powerful and scalable product, using the latest and fastest technologies.

The Pull Request Paradox: Merge Faster by Promoting Your PR

Aggregated on: 2021-12-18 00:34:21

The Pull Request Paradox explained I just wrote some code that can have a positive effect on our customers and I’m motivated to release it as quickly as possible. I need your help but you are busy and motivated to continue working on your own code. This conflict is The Pull Request Paradox. A very, very brief history of pull requests Pull requests came from the open source world and were born out of necessity. We needed a way to help open source projects manage submissions from contributors all around the world. GitHub built a solution for open source and Git flow went on to become widely adopted in the corporate world too. Despite the fact that most teams using it were working in the office. Of course in the last two years we’ve come full circle with remote work. So does that mean pull requests are more relevant than ever? Maybe.

Community AMA: Adam Furtado and Scaling Kessel Run

Aggregated on: 2021-12-18 00:34:21

How will the wars of the future be fought, and who is heading these advancements in technology? Back in 2017, the US Air Force created a program called Kessel Run, which aids war fighters in the realms of DevOps, Agile, and UX, and the head of this project was an analyst by the name of Adam Furtado. In February of 2021, we interviewed Adam on the Dev Interrupted Podcast and shortly afterward hosted an AMA on our community Discord server. Adam is the Chief of Platform at Kessel Run, and his story of how he almost single handedly led the US Air Force from 1970's software delivery methods to modern DevOps is one of the most incredible episodes of Dev Interrupted we've had. Adam talks about translating engineering to military officials and how he had to shift his mindset from application development to creating a system of systems. Listen to the episode here:

Externalizing Configurations in Kubernetes Using ConfigMap and Secret

Aggregated on: 2021-12-17 18:34:20

Configurations are attributes needed by an application when it runs. These configurations are values that are used frequently across the application. They may be used to provide dynamic behavior of an application based on customer, geographical region, language, and locale. Frequently used configurations are database URL, username, password, etc. These values are not hardcoded along with the application code as they may change depending on different factors. There is a 12 Factor recommendation that advises separate configuration out of code. Now the question arises if configurations are to be separated from code, how the application will access them during runtime. The answer is PLATFORM. Platform means the system on which the application runs. The configurations would be added on the platform as environment variables.

Auto Logging in Class and Method Level Using Custom Annotations in Spring Boot App

Aggregated on: 2021-12-17 18:04:20

It doesn't matter which type or size of software application we are developing, we all come to a point where we want to do a process over and over again but also don't want to re-implement or make a recall every time. This situation is not new nor it is valid for one case. There are many different variations for this situation and as a result many solutions. I would like to stage one of these solutions in a process common for all applications: Logging. I will be creating a spring boot application and will benefit from AOP.

How to Translate Android Text in JetPack Compose

Aggregated on: 2021-12-17 18:04:20

Sometimes there are projects where Android’s native text management system falls short. For example, if we wanted to fix a translation error, adjust an explanation or add a new language without having to deploy a new version of the application, the Android system would not allow us to do so. In Apiumhub's case, we have an application with this problem. The client has a portal from which it manages translations and can modify texts or add new languages without having to deploy new versions of the application.

What Are Expressions in AngularJS?

AngularJS is one of the most trusted frontend frameworks by enterprises. The frontend framework has multiple features that work the best for developers. In this section, we will learn about the use of expressions in AngularJS. Definition: Expressions in AngularJS are used to bind data with HTML. The AngularJS expressions are code snippets like that in JavaScript, which are usually placed in the interpolation bindings. However, you can directly make use of expressions in directive attributes.

Using the Shadow DOM to Isolate Styles on a DOM You Don't Own

Aggregated on: 2021-12-17 17:34:20

There have been many times in my career of building web apps and frontend experiences that I have needed to embed a widget in a DOM that I did not build or have access to — for example, embedding e-commerce widgets in a CMS or building Chrome extensions to augment a given website. One of the biggest frustrations I've had is the "style collision." In my development environment, all the widgets look great, but the second I add the widget to a customer’s page… everything is broken! Why Does This Happen? The difficulty with embedding widgets in a DOM that you don't own is every DOM is going to reference different default fonts and colors. It’s normal for a CSS stylesheet to look like:

Ever since Amazon Web Services debuted in 2008, builders of complex engineering software systems have had increasingly powerful ways to scale heavy computational workloads in the cloud. Calculations that previously would have required the purchase of dozens of expensive servers can now be executed at a fraction of the cost in AWS, Azure, or Google Cloud. Unfortunately, not all engineering software packages are server-based, much less cloud-based.

Inverted Triangle Architecture for CSS (ITCSS)

Aggregated on: 2021-12-17 16:49:20

The concept of modular CSS started to emerge years ago. All of us developers who have worked with CSS have had to deal with the difficulty of making our styles scalable and maintainable when our projects start to grow and, in addition, several people collaborate. That is why numerous methodologies have emerged to make our work easier. These methodologies are not found in any library or technology, they are more of a guide to help organize our CSS. The best known are OOCSS (Object Oriented CSS), SMACSS (Scalable and Modular Architecture for CSS), BEM (Block, Element, Modifier), and ITCSS (Inverted Triangle CSS).

Access Logs and Performance Issue Analysis

Aggregated on: 2021-12-17 16:49:20

An access log is a log that is generated by the webserver which logs the details about the request that it processed, along with the status code and the response time it took to process. Similar log files can be found in the load balancers as well, which will have similar details stored. While doing any performance analysis, these logs play an important role and it is being neglected most of the time due to lack of awareness. Also, the usage of APM tools abstracts it from the users by allowing them to focus on visually coarse-grained data instead of fine-grained data. Most people are aware of application server logs but many of them are not aware of web server/load balancer access logs. Access logs are available for the below servers but the format will be different for each of them

Cloud App Security: Top 10 Preventions Developers Must Know

Aggregated on: 2021-12-17 16:04:20

Threat actors regularly try to find and exploit application security vulnerabilities in an effort to steal data, install malicious code, or disrupt key business services. The increased focus on targeting vulnerabilities in cloud and web applications reflects a shift from the predominantly device and network-based attacks of the past. The perception among cybercriminals is that developers prioritize functionality over security, which makes applications and the cloud infrastructure they are hosted on an easy target. Adversaries exploit inadequate security controls, default configurations, and misconfigurations in applications and cloud infrastructures (such as AWS, Azure Cloud, etc). Developers have a crucial role to play in securing applications against today’s cyber threats, and it’s crucial for any developer to understand the latest practices in application security. This article provides an overview of the ten top things developers and businesses alike must know if they want to code secure applications and protect their vital information assets.

1000 Eyes That Don’t Want To Check Open-source Code

Aggregated on: 2021-12-17 16:04:20

There's a myth that open-source software is better and safer than a closed one. This was reasonably questioned many times. People regularly find epic vulnerabilities in the open-source code. These vulnerabilities have been there for a long time. I think the project quality depends on how the development managers arrange the process and what methodologies/tools are used. It has nothing to do with the project being open source or closed source. However, this myth is still alive. People believe that a thousand eyes can inspect the code, and someone will find an error. I think you've got the idea.

From that almost life-threatening experience, I am sharing the process, findings, and lessons.

Coordinating an Apache Ignite Cluster With GridGain Control Center

Aggregated on: 2021-12-17 11:04:20

Bundling various data sources, APIs, services, applications, and several data streams while managing application data integration can become cumbersome. It’s so complex that it typically results in application performance loss. So, database administrators use Apache Ignite, a distributed database that provides high-performance computing capabilities using in-memory speed. Integrating Apache Ignite as an in-memory caching or distributed database solution helps improve the velocity and performance of complex architecture. But, at the same time, this solution presents new challenges: we’re integrating yet another component into our already complex architecture. GridGain provides a solution to this challenge enabling monitoring, managing, and troubleshooting Apache Ignite clustered environments, whether they’re running as an on-premises solution or as a SaaS offering in the cloud.

Slow Build Pipeline? Build Faster by Building Only What You Need

Aggregated on: 2021-12-17 10:34:20

In today’s fast-paced software world, organizations need to deliver fast, as fast as multiple times per day. Agile methodologies and DevOps culture have contributed to enabling this constant delivery. Continuous integration and continuous delivery (CI/CD) is an almost basic requirement for any company that wants to remain competitive in the market. CI/CD allows the delivery of code changes more frequently and reliably by automating the required steps to take a working piece of software to a production environment. This automation comprises a set of steps to compile, build, and deploy code is called a “building pipeline.”

Spring Cloud Stream With Kafka

Aggregated on: 2021-12-17 09:49:20

Introduction Spring Cloud Stream, is a mechanism by which you can decouple the implementation of your producers and consumers from the type of messaging infrastructure you want to use. This allows us to keep our consumers and producers to be broker agnostic and we can easily switch to a different kind of broker by changing the binder implementation. There are quite many binder implementations like e.g Kafka, RabbitMQ, AWS SNS, AWS SQS, etc. You can find a list of available binder implementations here.

According to this study, such intuition is justified. The authors examine code review coverage on open source codebases and find that:

Massive Shift to Remote Learning Prompts Big Data Privacy Concerns

Aggregated on: 2021-12-16 18:19:20

Don't think that the introduction of quarantine was an opening for hacking educational institutions. Hacker attacks began long before the COVID-19 pandemic and the mass shift to online learning. A year ago, the school district in San Bernardino, California, became the target of ransomware attacks. According to Tessian, the University of Utah and the University of California paid ransom payments of $457,000 and $114,000 respectively to gain access to their systems. Secondary education institutions (below the college level) are the most vulnerable to hacking. Cyberattacks on schools are cheap for criminals, but it can cost the schools themselves millions of dollars to prevent or recover from them. School districts simply do not have the resources, both financial and human, to handle such attacks.

EclipseCon 2021 took place October 25-28. EclipseCon has long been a world-class conference for all things Eclipse. With the Java EE transition to the Eclipse Foundation, EclipseCon has become a truly significant event for Jakarta EE and MicroProfile developers. Due to the pandemic, the 2021 event was virtual (and free!). Jakarta EE unsurprisingly had a strong presence at the conference with talks on Jakarta EE 9.x, Jakarta EE 10, MicroProfile 4.x, MicroProfile 5, Jakarta Security, Jakarta Concurrency, Jakarta REST, Jakarta NoSQL, and MicroProfile GraphQL from speakers such as Tanja Obradovic, Ivar Grimstad, Josh Juneau, Otavio Santana, Emily Jiang, Steve Millidge, Arjan Tijms, Werner Keil, Ed Burns, Rudy De Busscher, and Graham Charters.

The Full-stack Dev Is Bent Out of T-shape

Aggregated on: 2021-12-16 09:34:19

There are still plenty of openings for full-stack developers. If the stack is the gamut of programming languages, protocols, and middleware to build and maintain a serious internet application, then a full stack developer is the digital Jack of all trades who, contrary to the saying, has mastered them all. I once called myself such, and in 2001 it wasn’t necessarily an act of youthful hubris. The popular LAMP stack (Linux, Apache, MySQL, and Perl) was still manageable. Perl lost most of its popular appeal, while Linux and MySQL stay relevant and dominant. Unfortunately, the stack of old has grown to a high-rise. This is understandable: applications need to do lots more and interact with vital services that have become the backbone of modern societies. It’s serious business. Cybercrime is an increasingly attractive business model. Knowing about security is not optional. Before smartphones, there was only the browser platform to grapple with – although the battle between Netscape and Explorer (my standard is more standard than yours) drove everybody mad.

Using TypeDB for Autonomous Vehicles

Aggregated on: 2021-12-16 01:34:19

The team at TNO set out to combine knowledge of human driving — e.g. ethics, laws, norms, preferences, common environmental understanding — with the technological side of autonomous driving — e.g. control theory, data-driven AI, black-box algorithms (DNN), and end-to-end learning. To achieve this and be able to reason over the collective knowledge, they used TypeDB. An example where the combination of this knowledge demonstrates its value is when hardcoded knowledge meets contextual knowledge of a given situation in time. Let’s say an autonomous vehicle is programmed to drive slower in school zones, obviously needed for safety, but what about when the school is closed? Does the vehicle still need to drive at a slower speed?

Building an Employee Survey Dashboard with Supabase and N8N

Aggregated on: 2021-12-16 01:34:19

Many companies use questionnaires to keep track of their employee’s health and general wellbeing. Because of the time and complexity involved in building one, many choose to go ahead with off-the-shelf solutions that may be quick to set up but have poor analytics tools. For example, the organization might be interested in knowing specifics about the use of the survey/questionnaires. But there’s something better than off-the-shelf, and it can be built using Appsmith. In this article, I will teach you how to build a custom employee survey dashboard to fit your specific requirements. We’ll achieve this by tying together the best open-source tools in the business to build powerful workflows.
