Code Quality defines that the code is good, which means code is of high quality, and code is bad, which means code is of low quality. Code can be considered good quality if it is clear, simple, well tested, bug-free, refactored, documented, and performant.
Nobody loves to work on legacy code because it can be a confusing endeavor; at best, it’s time-consuming. But do we now live with the huge repercussions and costs of retaining and utilizing legacy codes as they are?
In this article, we analyze the policies of block allocation from the source code. How does an Alluxio worker decide which directory to put a block in when a user reads or writes data through Alluxio?
But to be scalable, they also need low-code/no-code solutions that don’t require a lot of spin-up or engineering expertise. With the Dynatrace modern observability platform, teams can now use intuitive, low-code/no-code toolsets and causal AI to extend answer-driven automation for business, development and security workflows.
Regarding contemporary software architecture, distributed systems have been widely recognized for quite some time as the foundation for applications with high availability, scalability, and reliability goals. Spring Boot's default codes and annotation setup lessen the time it takes to design an application.
With the increasing amount of sensitive information stored and processed, it’s essential to ensure that systems are secure and protected against potential threats. The deep insights into application code provided by OneAgent® help track potentially vulnerable data flow within an application.
Here’s how Dynatrace can help automate up to 80% of technical tasks required to manage compliance and resilience: Understand the complexity of IT systems in real time Proactively prevent, prioritize, and efficiently manage performance and security incidents Automate manual and routine tasks to increase your productivity 1.
In software development, maintaining high code quality and reliability is crucial for building robust applications. A key metric for gauging testing effectiveness is code coverage, which measures the percentage of code executed during automated tests. While traditional code coverage offers valuable insights, it has limitations.
Behind the scenes, a myriad of systems and services are involved in orchestrating the product experience. These backend systems are consistently being evolved and optimized to meet and exceed customer and product expectations. This technique facilitates validation on multiple fronts.
When we discuss code profiling with a team of developers, they often say, "We don't have time to profile our code: that's why we have performance testers ," or, "If your application or system runs very slowly, the developers and performance testers may suggest the infra team to simply add another server to the server farm."
SQL Server is a powerful relational database management system (RDBMS), but as datasets grow in size and complexity, optimizing their performance becomes critical. In this article, we will explore how AI can assist in these areas, providing code examples to tackle complex queries.
Today, we discuss C# code quality and a variety of errors by the example of CMS DotNetNuke. We're going to dig into its source code. DotNetNuke is an open-source content management system (CMS) written mainly in C#. The source code is available on GitHub. You're going to need a cup of coffee. DotNetNuke.
All four players involved in the device were on the call: there was the large European pay TV company (the operator) launching the device, the contractor integrating the set-top-box firmware (the integrator), the system-on-a-chip provider (the chip vendor), and myself (Netflix). Next I started reading the Ninja source code.
This is where large-scale system migrations come into play. By tracking metrics only at the level of service being updated, we might miss capturing deviations in broader end-to-end system functionality. Canaries and sticky canaries are valuable tools in the system migration process.
When organizations move toward the cloud, their systems also lean toward distributed architectures. You need to find the right tools to monitor, track and trace these systems by analyzing outputs through metrics, logs, and traces. One of the most common examples is the adoption of microservices.
For the CrowdStrike issue, one can use both monitored Windows System logs and the Dynatrace entity model to find out what servers are impacted. The following is an example of a query using the Dynatrace Query Language (DQL) to find out when BSOD issues are being written to Windows System logs.
It's not just about avoiding hardcoding secrets into your code, your CI/CD configurations, and more. It's any bit of code, text, or binary data that provides access to a resource or data that should have restricted access. Managing your secrets well is imperative in software development.
But with this complexity comes fragility and lack of transparency into system performance and reliability. By leveraging Davis AI and other core platform capabilities, Dynatrace provides intelligent observability and automation from code to production to help teams build, run, and optimize modern cloud-native applications.
As dynamic systems architectures increase in complexity and scale, IT teams face mounting pressure to track and respond to conditions and issues across their multi-cloud environments. How do you make a system observable? Dynatrace news. But what is observability? Why is it important, and what can it actually help organizations achieve?
Thanks to the Netflix internal lineage system (built by Girish Lingappa ) Dataflow migration can then help you identify downstream usage of the table in question. All the code you get with the Dataflow sample workflows is fully functional, adjusted to your environment and isolated from other sample workflows that others generated.
Whether deployment of a new system, a new release, or a rolling patch update, I wanted it done consistently and successfully every time. Years later, a few configuration management solutions came into play that required heavy amounts of coding, but proved that the industry was moving toward compartmentalized automation solutions.
Software bugs Software bugs and bad code releases are common culprits behind tech outages. These issues can arise from errors in the code, insufficient testing, or unforeseen interactions among software components. Ransomware encrypts essential data, locking users out of systems and halting operations until a ransom is paid.
It sits at the very beginning of the process before the code is written and can save an immense amount of time down the road (of somebody spending tons of time just to get to a dead-end). I really like what one of the smartest people with whom I worked said: “A good design is a design where you can see the code”. Important note.
Modern observability and security require comprehensive access to your hosts, processes, services, and applications to monitor system performance, conduct live debugging, and ensure application security protection. Changes are introduced on a controlled schedule, typically once a week, to reduce the risk of affecting customer systems.
You write your code, and the cloud provider handles the rest - provisioning, scaling, and maintenance. Reduced operational overhead: Developers can focus purely on writing code and pushing updates, rather than worrying about server upkeep. AWS offers various serverless services, with AWS Lambda being one of the most prominent.
These services can be developed and maintained separately, promoting code modularity and enhancing overall system agility. Instead of treating the entire application as a monolithic entity, microservices architecture allows us to identify distinct features like search, shopping cart, payments, and order history as independent services.
Indeed, according to one survey, DevOps practices have led to 60% of developers releasing code twice as quickly. But increased speed creates a tradeoff: According to another study, nearly half of organizations consciously deploy vulnerable code because of time pressure. Increased adoption of Infrastructure as code (IaC).
In the realm of system debugging, particularly on Linux platforms, strace stands out as a powerful and indispensable tool. Its simplicity and efficacy make it the go-to solution for diagnosing and understanding system-level operations, especially when working with servers and containers.
This decision, seemingly technical at its core, extends far beyond the area of coding, straight into the strategic planning that can make or break the early stages of a startup. The appeal of building a system that's inherently designed to grow and adapt as the startup evolves is undeniable.
Our industry is in the early days of an explosion in software using LLMs, as well as (separately, but relatedly) a revolution in how engineers write and run code, thanks to generative AI.
We are well aware of what is meant by system scalability. System scalability is about maintaining the SLA of the system as the user base continues to grow and as the user activity continues to rise. As our user base increases, our systems reach hyper-scale (which is a good thing!).
On Titus , our multi-tenant compute platform, a "noisy neighbor" refers to a container or system service that heavily utilizes the server's resources, causing performance degradation in adjacent containers. We categorize it as a system service if no such association is found.
The vulnerability enables an attacker to gain control over a string and trick the application into requesting and executing malicious code under the attacker’s control. The amount of recordable data is broad, and ranges from basic user browser and web page information to detailed technical information about the system Log4j 2 is running on.
Secrets can be leaked in many ways, including through version control systems ( never hardcode any secrets in your code ), private messages, email, and other communication channels. Secrets, such as database passwords, API keys, tokens, etc., must be managed appropriately to avoid any breach.
However, to be secure, containers must be properly isolated from each other and from the host system itself. Four types of tools are commonly used to detect software vulnerabilities: Source-code tests that are used in development environments. Network scanners that see systems from the “outside” perspective.
System Testing. Unit testing ensures that every piece of code written in a segment produces the best results. It provides documentation of code progression because each unit of code is thoroughly tested before moving on to the next. There are various types of functional testing, that are as below: Unit Testing.
The vulnerability, affecting the XZ Utils data compression library that ships with major Linux distributions, is logged under CVE-2024-3094 and boils down to a backdoor deliberately inserted by a once-trusted volunteer system maintainer, who managed to socially engineer his way to a position of trust before turning rogue.
With CI, multiple software developers can work on different features or modules of the same application and individually commit their updates to a shared code repository as they complete them, often many times a day. When they check in their code, the build management system automatically creates a build and tests it.
By Jun He , Natallia Dzenisenka , Praneeth Yenugutala , Yingyi Zhang , and Anjali Norwood TL;DR We are thrilled to announce that the Maestro source code is now open to the public! Maestro supports dynamic parameters with code injection, which is super useful and powerful. Please visit the Maestro GitHub repository to get started.
Infrastructure as Code on Azure - ARM. These days, most developers are familiar with the concept of having our applications’ and systems’ infrastructure defined in descriptive and version-controlled code which generates the same environment, every time it’s applied.
Reference data sources don’t always require ACID transaction capabilities, rather need support for fast read queries often based on simple data access patterns, and event-driven architecture to ensure the target systems remain up-to-date.
Reverse debugging is a debugging system that makes it possible to stop code execution and move backward (and forward) in the code’s history to discover the cause of failure in a program. Reverse debugging involves remote debugging, debugging on the same machine, or debugging on a simulator.
They enable product delivery and SRE teams to turn functionality on and off at runtime without deploying new code. This decoupling of code deployment from feature release is a crucial enabler for modern Continuous Delivery practices. Proprietary SDKs create adoption challenges.
It is a software testing technique to examine the functioning of software from an external outlook without digging deeper into its code. The best thing about Black box testing is that it can be applied to all levels of testing ( Unit, integration, system, and acceptance).
