Dynatrace news. DevSecOps is a cross-team collaboration framework that integrates security into DevOps processes from the start rather than waiting to address security in a separate silo. With an integrated DevSecOps approach, organizations can reduce security risk without derailing development timelines. But what exactly does this mean? How is it different from DevOps, and what’s next for the relationship between development, security, and operations within enterprises?
API Test is crucial for the software systems to function at high quality. Every app you build nowadays completely relies on Application Programming Interfaces. Application Programming Interface acts as the center level between the database and presentation layer in the software development procedure. It is mainly the channel that links the client to the server, drives business procedures, and gives the services which give worth to users.
The notions of accountability and responsibility often pop up in the context of business, as if both of those ideas are good things. A culture of accountability, we’re told, is essential to running a business. The word “accountable” appears all over the 2020 Scrum Guide, as if it’s somehow an Agile notion instead of capitulation… The post #NoAccountability appeared first on Allen Holub.
Have you heard the hype around k6 yet? Yes, yet another open source performance testing tool is making waves. In this post, I’ll share my k6 review in. The post k6 Review: Open Source Load Testing Tool for Developers appeared first on Abstracta Software Testing Services.
Dynatrace news. The phrase “serverless computing” appears contradictory at first, but for years now, successful companies have understood the benefit of using serverless technologies to streamline operations and reduce costs. Still, this model is not ideal in every situation. So what exactly does “serverless” mean, and how can your organization benefit from it?
Introduction. Whether we like it or not, outliers happen in our daily lives! For instance, it can be a mansion that sells in your neighbourhood for a price three to four times higher than the average house price. In the workforce, it can also be a few professionals earning very high salaries when compared to the rest of the employees. Or if you were to look at the arrival times of planes at your local airport, you would see that most planes land in a [0.10min] interval around the scheduled arriv

Fleet vehicle maintenance has evolved with time - right from reactive to preventive to now predictive, there has been a paradigm shift in maintenance. Here, we are analyzing predictive maintenance, the role of custom software can play in it, and how emerging technologies have made this shift possible while reducing operational costs and increasing vehicle efficacy.
The meteoric emergence of smartphones is nothing short of phenomenal, as a growing number of consumers are leveraging the potential offered by the smartphone ecosystem. As per April 2019 data of Statistica[1], the global mobile population accounted for 4 billion unique users. That’s not all, the global mobile traffic is expected to increase sevenfold between 2017 and 2022.
One thing that jumped out while working on the JavaScript chapter of the Web Almanac was the incredibly high amount of time spent processing JavaScript on the median mobile page where Ember.js was detected. (The story was the same when I wrote The Cost of JS Frameworks. ). What we found was that the median site using Ember.js spent 21.9s dealing with JavaScript when loaded on an emulated mobile device.
In my estimation, I have given over 2,500 interviews in my career, the bulk of them for Software Engineer positions. I have been interviewing Software Engineers for over 25 years and in my current role as CEO of Solution Street, I conduct, on average, two interviews a week. Solution Street has been evolving its interview process for over 18 years, and we feel like we offer a pretty robust and fair process.
As a system grows, higher-order abstractions are needed for ease of understanding, communication, and management. In Geography, continents are a higher order abstraction that allow us to collectively describe a large number of countries in a single word. As businesses grow, higher order abstractions are needed to organize groups of teams working on related challenges, like products or domains.
In this article, we will discuss how to read the SQL Server execution plan (query plan) with all aspects through an example, so we will gain some practical experience that helps to solve query performance issues. Interpreting query plans correctly is the first and major principle to troubleshoot query performance issues. When we try to […].
Agile In-Memory Software Can Track the Dynamic Rollout of Vaccine Distribution and Delivery to Quickly Spot Problems. Getting the COVID-19 crisis under control requires that we put in place an effective process for vaccine distribution so that the country can get to herd immunity as fast as possible. We are faced with quickly building a nationwide logistics network and standing up well more than 50,000 vaccination centers.
In this interconnected age, integration is essential for software applications. Your users expect instant access to the information they want, even if that data resides within another application. That’s why APIs have become so integral in presenting a seamless user experience across software apps. That is, if the APIs deliver results correctly. Any issue with an API can halt users from continuing to use your product.
If you’re in the technology space, you’ve probably stumbled upon Hacker News at some point or another. Maybe you’re interested in knowing what’s popular this week for technology or maybe you have something to share. It’s a platform for information. The problem is that you’re going to find too much information on Hacker News without a particularly easy way to filter through it to find the topics that you’re interested in.
This special Guru of the Week series focuses on contracts. We covered basic assertions in GotW #97 … but not all asserted conditions are created equal. Given some assertion facility that can be used like this: MyAssert( condition ); // expresses that ‘condition’ must be true 1. Give one example each of an asserted condition whose run-time evaluation is: a) super cheap Without resorting to constexpr expressions, it’s hard to find one cheaper than the one we saw in GotW #97 Example 3, which we can
Modern day fleet owners face a whole new range of challenges that didn't exist before. The cutthroat competitions and logistical challenges posed by the pandemic don't make things any easy, as well. In this article, we introduce you to some emerging technologies that are well on their way to be the game changers for the fleet management industry. Read more to find what they are and how they can help your fleet.
While creating the OBD2 reader application, we faced many questions, problems, and so on, so we will try to acquaint you with them in this article. As it turned out, you can conduct a dialogue with the car, and quite a productive one. However, in order to start communicating with the car, it is necessary to "establish contact", "ask the right question" and correctly understand the "answer" received from the car.
At the recent Forrester Technology & Innovation Global Summit , René Te-Strote—Senior Project Lead of the BMW IT Group—spoke with our CEO and founder, Dr. Mik Kersten, about BMW’s ongoing transformation in the Age of Software. Expanding on the significant role that virtual product development plays in modern automotive manufacturing, René and Mik discussed how value stream management (VSM) has enabled BMW to successfully expand its presence in the Chinese market.

This special Guru of the Week series focuses on contracts. Postconditions are directly related to assertions (see GotW #97 )… but how, exactly? And since we can already write postconditions using assertions, why would having language support benefit us more for writing postconditions more than for writing (ordinary) assertions? JG Question 1. What is a postcondition, and how is it related to an assertion?
If you need to dynamically trace Linux process system calls, you might first consider strace. strace is simple to use and works well for issues such as "Why can't the software run on this machine?" However, if you're running a trace in a production environment, strace is NOT a good choice. It introduces a substantial amount of overhead. According to a performance test conducted by Arnaldo Carvalho de Melo, a senior software engineer at Red Hat, the process traced using strace ran 173 times slowe
A Chief Product Officer (CPO) and a Chief Financial Officer (CFO) walk into a bar. Just kidding – I have no CFO and CPO bar joke. But at the same time, the image itself is amusing; it probably doesn’t induce belly laughter, but a smirk maybe? Or perhaps even a wince? Or maybe just plain bewilderment. Why is that? It seems the two roles not only speak a different dialect but an entirely different language.
Automation testing is vital to the entire process of delivering a successful web product. The challenge associated with testing a web site or web app grows exponentially if it’s built for a global audience (particularly non-English audience). Automation tests have to be performed to ensure that the product features (including the content) cater to specific locales.
What do you think about cross-browser testing ? Developers likely develop on only one browser – and maybe only one operating system. How does an app maker ensure that defects on other browsers will not affect their user base? In theory, cross-browser testing can help companies catch product defects before products get released to customers. But the legacy approach – setting up a bunch of parallel devices and running tests across each – incurs significant engineering skill and resource cost.
In a production environment, filesystem faults might occur due to various incidents such as disk failures and administrator errors. As a Chaos Engineering platform, Chaos Mesh has supported simulating I/O faults in a filesystem ever since its early versions. By simply adding an IOChaos CustomResourceDefinition (CRD), we can watch how the filesystem fails and returns errors.
