What is DevSecOps and what is a DevSecOps maturity model? DevSecOps brings development, operations, and security teams together in the software development lifecycle (SDLC). This approach enables teams to focus on speed and agility in software development without compromising security. A DevSecOps approach advances the maturity of DevOps practices by incorporating security considerations into every stage of the process, from development to deployment.
I apologize for this title because there are many things that can make modern software slow. Blindly applying one explanation without a bit of investigation is the software equivalent of a cargo cult. That said, this post describes one example of why modern software can be painfully slow. All I wanted was to record a forty-second voiceover for a throw-away video , so I fired up the Windows Voice Recorder app and hit the record button.
Alluxio workers are responsible for managing local resources, and they store data as blocks. Users can allocate different storage tiers as the resources for Alluxio workers, including MEM/SSD/HDD, which are further composed of directories. How does an Alluxio worker decide which directory to put a block in when a user reads or writes data through Alluxio?
I have long held very strong opinions about the Critical CSS pattern. In theory, in a perfect world, with all things being equal, it’s demonstrably a Good Idea™. However, in practice, in the real world, it often falls short as a fragile and expensive technique to implement, which seldom provides the benefits that many developers expect. Let’s look at why.
Timestone: Netflix’s High-Throughput, Low-Latency Priority Queueing System with Built-in Support for Non-Parallelizable Workloads by Kostas Christidis Introduction Timestone is a high-throughput, low-latency priority queueing system we built in-house to support the needs of Cosmos , our media encoding platform. Over the past 2.5 years, its usage has increased, and Timestone is now also the priority queueing engine backing Conductor , our general-purpose workflow orchestration engine, and BDP Sch
One of the great things about Google's Core Web Vitals is that they provide a standard way to measure our visitors’ experience. Core Web Vitals can answer questions like: When was the largest element displayed? Largest Contentful Paint (LCP) measures when the largest visual element (image or video) finishes rendering. How much did the content move around as it loads?
Kubernetes is used by many organizations to build, deploy, and manage large-scale distributed applications. However, the overwhelming advantage of running applications on Kubernetes comes at a cost. Progressive rollouts, rollbacks, storage orchestration, bin packing, self-healing, cost efficiency, and access to the Cloud Native Computing Foundation (CNCF) ecosystem carry heavy observability challenges.

It is a fact that software testing is time and resources consuming. Testing the software can be observed from different perspectives. It can be divided based on what we are testing. For example, each deliverable in the project, like the requirements, design, code, documents, user interface, etc., should be tested. Moreover, we may test the code based on the user and functional requirements or specifications, i.e., black-box testing.
The need to manipulate data at the bit level with bitwise operations isn’t common in T-SQL, but you might stumble into such a need in some specialized scenarios. Some implementations store a set of flags (yes/no, on/off, true/false) in a single integer or binary-typed column, where each bit represents a different flag. One example is using a bitwise representation of a set of user/role permissions.

Site reliability engineering seeks to bridge the gap between developers and operations teams, embedding reliability and resiliency into each stage of the software development lifecycle. Site reliability engineering (SRE) is a key component of digital transformation. Still, many organizations have found that the transition to SRE maturity is not always easy.
[Edited to add pre-publication link to next draft of P2392, revision 2, and correct iterator comparison] Brief background As I presented at CppCon 2021 starting at 11:15 , I’m proposing is (a general type or value query) and as (a general cast, for only the safe casts) for C++ evolution. The talk, and the ISO C++ evolution paper P2392 it’s based on, explained why I hope that is and as can provide a general mechanism to power pattern matching with inspect , while conversely also liber
Have you ever dreamed of making or taking your company to the level of Amazon? Of course, Amazon didn't become one of the most valuable brands in the world. But still, do you think it could get this bigger if Jeff Bezos would not put his maximum effort, take risks, and keep his small book-selling site up-to-date with modern technologies? We all know that Amazon does automate not only its operations but also streamlines the business for sellers who use the platform.
The NServiceBus messaging pipeline strives to achieve the right balance of flexibility, maintainability, and wicked fast…ummm…ability. It needs to be wicked fast because it is executed at scale. For our purposes, “at scale” means that throughout the lifetime of an NServiceBus endpoint, the message pipeline will be executed hundreds, even thousands of times per second under high load scenarios.
This article isn’t about the act of lock escalation itself, which is already well documented and generally well understood. Some myths (like row locks escalating to page locks) persist, but challenging those yet again probably wouldn’t change much. Instead, the question I’ll address here is exactly how and when lock escalation is triggered. Much of the documentation is incorrect or at least imprecise about this and I’ve been unable to find a correct description in other writings.
From banking and retail to healthcare and government, nearly all industries have experienced a dramatic shift to mobile computing over the last decade. More and more end users are completing transactions, playing games, consuming content, and interacting with others on mobile devices. Some services, such as car-sharing, are executed exclusively on mobile devices.
It was great to see many of you at CppCon, in person and online! It was a really fun conference this year, and the exhibitor hall felt crowded again which was a good feeling as we all start traveling more again. The talk I gave on Friday is now on YouTube. In it I describe my experimental work on a potential alternate syntax for C++ (aka ‘syntax 2’ or Cpp2 for short) and my cppfront compiler that I’ve begun writing to implement it.

What can it give back to you? Lots of stuff: sharping your professional skills and obtaining diversified experience, enriching your portfolio, connecting with open source community an
Configuration testing plays a critical part in the development life cycle by specifying the quality and portability of software. It helps to understand whether a program can be used on any operating system other than the one for which it was designed. Or whether there is any work required to make software run in the new environment. Let’s find out what is configuration testing with an example and how does it work?

Warning: The following are notes I've taken during an analysis I made upon tools and methodologies for monitoring and observing distributed systems. After the work, I reviewed them to make them a little bit more discursive. My primary goal was to evaluate the use of Prometheus to observe systems enforcing the exposure of contextual metrics of the system's specific business.
If DevOps implementation is one of the obstacles you have successfully conquered, your battle has just begun. Analyzing the right metrics and KPIs gives you a clear picture of your business growth, its current performance, and things that require improvement.
If you facilitate or attend domain discovery workshops, one of the most effective and simplest ways to uncover insights is to make the scale or size of something explicit. The scale of something influences the importance and how we treat it. Making scale explicit can lead to all kinds of insights, like where the biggest opportunities to improve a product can be found.
Application modernization is a means to help organizations survive in a digital world. Today, organizations must adopt solid modernization strategies to stay competitive in the market.
