Rapid Debugging With Proper Exception Handling

Aggregated on: 2023-03-29 17:30:05

As a developer, often the most irritating part of development is debugging. Most programmers I have worked with would echo this sentiment. Often the first reaction to seeing an exception is a mixture of annoyance and frustration. Exceptions that are easy to debug yield the root cause often within a few minutes of debugging. The ones that annoy me the most are the ones that happen days after the system has been running properly in production, and their stack traces lead to a dead end. However, well-written code which manages exceptions properly not only helps you debug issues faster but, in certain situations, can help systems recover automatically without intervention. Fortunately, there are some simple and effective tools that you can use to reduce the time you spend debugging the latter kind of exceptions. Often this technique doesn't really improve the reliability of the software that you are developing(At Least not at first), but it becomes much easier to root cause an issue and come up with a fix for it.

Important Takeaways for PostgreSQL Indexes

Aggregated on: 2023-03-29 04:30:05

This is how PostgreSQL's official documentation defines Indexes, pretty simply and clearly — "Indexes are a common way to enhance database performance. An index allows the database server to find and retrieve specific rows much faster than it could do without an index. But indexes also add overhead to the database system as a whole, so they should be used sensibly." The last word, "sensibly," in this definition, is the crux of this article. Indexes are good, and they enhance the performance of queries. This does not imply that we create Indexes for every query and every column. It is important to remember that while Indexes do enhance Performance, they do need to be maintained, and that is overhead.

Aggregated on: 2023-03-29 04:00:05

What Are Hub, Switch, Router, and Modem? In today's digital age, networking has become an integral part of our daily lives. Whether it's at home, in the office, or on the go, we rely on networks to connect us to the world around us. To establish and maintain these connections, various networking devices are used, including hubs, switches, routers, and modems. In this article, we will discuss each of these devices, their functions, and how they differ from one another. Hubs A hub is the simplest type of networking device, and it is typically used to connect multiple devices to a network. Hubs operate at the physical layer of the OSI model, which means they simply repeat incoming network traffic to all connected devices, regardless of whether or not the devices need the information. Because of this, hubs are not very efficient and can lead to network congestion.

Data Stream Using Apache Kafka and Camel Application

Aggregated on: 2023-03-29 03:00:05

Apache Kafka is an event streaming platform that was developed by LinkedIn and later made open-source under the Apache Software Foundation. Its primary function is to handle high-volume real-time data streams and provide a scalable and fault-tolerant architecture for creating data pipelines, streaming applications, and microservices. Kafka employs a publish-subscribe messaging model, in which data is sorted into topics, and publishers send messages to those topics. Subscribers can then receive those messages in real time. The platform offers a scalable and fault-tolerant architecture by spreading data across multiple nodes and replicating data across multiple brokers. This guarantees that data is consistently available, even if a node fails.

Automate Long Running Routine Task With JobRunr

Aggregated on: 2023-03-29 00:00:05

Today I shall explain a simple way to deploy, manage and monitor long-running background tasks, especially ETL systems. The common questions that every big data engineer would ask concerning a deployed ETL tool are the performance of the tool, what is causing the break in the processing pipeline, how easy it is to chain several jobs, and lots more. JobRunr makes it easy to schedule background long-running tasks. it is a distributed Java background job scheduler with lots of exciting features like scheduled and delayed jobs, fire and forget jobs, recurring jobs, queuing jobs and batches, and job chaining. Please note that some of these features are only available in the pro version. However, most of JobRunr's features are completely open-sourced. The library also provides a nice interface to manage and monitor all your jobs. I find this really fascinating as end users can adopt this visual for other useful purposes; for instance, from the UI, recurring jobs can be triggered manually, it provides a report on when next a job is expected to run, and users get to see nice-looking reports of each job processing time and also hardware performance information of the server where the application is deployed, isn't this exciting?

Don’t Overpay for Cloud: Six Mistakes To Avoid When Moving to the Cloud

Aggregated on: 2023-03-28 01:45:04

The public cloud is here to stay. Analyst surveys estimate that total public cloud spending will reach US$1T by 2025. The promise of reduced cost, on-demand provisioning, and innovative financial models are key drivers of this growth. However, as with any new technology, there are teething challenges. A pervasive CIO concern has been the seemingly out-of-control and opaque cloud bill and the associated lack of organizational governance around cloud costs. Unfortunately, by the time the CIO intervenes, it’s too late, as the money has already been spent. While optimizing cloud spend requires a hands-on approach to governance and forecasting, it does not require perfect knowledge of the future. The graph below illustrates that reservation-based discounts can deliver cost savings even when you can’t fully predict your upcoming cloud needs.

Technological Advancement in EV (Electric Vehicle) and EV Ecosystem

Aggregated on: 2023-03-28 01:30:04

The Electric Vehicle (EV) Market The Electric Vehicle (EV) current market share is under 5%, which is expected to grow to 24% by 2028, 40% by 2030, and 90% by 2040. Electric vehicle adoption is low due to high cost, limited driving range, and lack of charging infrastructure. The cost of electric vehicles is high. Not all people segment can afford to buy. There needs to be a huge surge in the cost to boost sales. Electric vehicles are powered by batteries. The driving range is limited to battery capacity. This is another major issue. One needs to stop the vehicle to recharge the battery once the maximum distance is reached according to battery capacity. Unlike petrol stations, there are not many EV charging stations. This is another major issue. Hence, it is important to know the nearby charging station before the battery gets drained fully. Unlike ICE-powered vehicles(Gasoline/Petrol or Diesel), Electric vehicle needs an ecosystem approach to drive EV adoption on a large scale. A piecemeal solution may not help. The solution needs to address all the following aspects of the ecosystem.

Orchestration Pattern: Managing Distributed Transactions

Aggregated on: 2023-03-27 22:15:04

As organizations migrate to the cloud, they desire to exploit this on-demand infrastructure to scale their applications. But such migrations are usually complex and need established patterns and control points to manage. In my previous blog posts, I covered a few of the proven designs for cloud applications. In this article, I’ll introduce the Orchestration Pattern (also known as the Orchestrator Pattern) to add to the list. This technique allows the creation of scalable, reliable, and fault-tolerant systems. The approach can help us manage the flow and coordination among components of a distributed system, predominantly in a microservices architecture. Let’s dive into a problem statement to see how this pattern works. Problem Context Consider a legacy monolith retail e-commerce website. This complex monolith consists of multiple subdomains such as shopping baskets, inventory, payments etc. When a client sends a request, the website performs a sequence of operations to fulfil the request. In this traditional architecture, each operation can be described as a method call. The biggest challenge for the application is scaling with the demand. So, the organisation decided to migrate this application to the cloud. However, the monolithic approach that the application uses is too restricted and would limit scaling even in the cloud. Adopting a lift and shift approach to perform migration would not reap the real benefits of the cloud.

Introduction to NoSQL Database

Aggregated on: 2023-03-27 18:15:04

NoSQL stands for "Not Only SQL" and refers to a type of database management system that is designed to handle large volumes of unstructured and semi-structured data. Unlike traditional SQL databases that use a tabular format with predefined schemas, NoSQL databases are schema-less and allow for flexible and dynamic data structures. NoSQL databases are required because they can handle the large volumes and complex data types associated with Big Data. They are designed to scale horizontally by distributing data across many servers, making them well-suited for handling large and growing datasets. Additionally, NoSQL databases are often faster and more efficient than SQL databases for certain types of queries, such as those involving large amounts of data and complex data structures.

We know that coding isn't just typing and that having crazy keyboard skills doesn't make you a great programmer. But even then, we focus mainly on code creation skills. Think for a moment about what most books, blog posts, and talks are about. What sparks the most heated discussions in your team? What are the most common coding interview questions?
