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.

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.

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

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.

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.

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?

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.

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?

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

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.
