5 Emotionally Intelligent Habits For Handling Frustration At Work


That sudden rush of anger when a coworker blames you, a feeling of disappointment when your idea is rejected, resentment towards an egocentric boss, and the stress of meeting other people's expectations can be a constant source of frustration at work.

Just like a rubber band you feel stretched to your limits, ready to break at any moment. One tiny push in the wrong direction can wreak havoc in your mind, break your world apart and distract you from being productive in your work.

Every single day there's so much to dislike about work. A boss who doesn't care, coworkers who are mean, clients who nitpick, a support team that doesn't care to respond, meetings that suck away into your time and energy, and emails and messages that live in a world of their own with no sense of time.

Ionic App Development Over Other Frameworks: Is It Hyped?

Developing a mobile application involves several tasks. There are only two major platforms of mobile applications- Android and iOS. Developers use kotlin and Java to build Android applications while use Objective C and Swift to develop iOS applications. The native development process offers premium performance and API integration and easy to access hardware devices and much more.

One thing you need to keep in mind while doing native app development is that it’s costly, and it depends on the number of platforms you want to cover. This means different applications from different platforms, two codebases, two separate development projects, double the expenses.

Application Development for Embedded Systems

Embedded systems are growing smarter and intelligent across embedded domains. Thanks to the remarkable advancements in the field of electronics, especially wireless communication technologies, SoCs, Microcontrollers, FPGAs, networking techniques, and cognitive computing among others that support ultra-fast communication and data exchange. The trend is spanning across the embedded landscape including automotive, industrial automation, semiconductor, consumer electronics, avionics, energy, and healthcare domains.

While we talk about the explosive growth of embedded systems, we cannot ignore one significant factor that is fostering these advancements — Embedded Apps. Needless to say, embedded apps, with their advanced features as well as intuitive and user-friendly nature, are becoming key to any technological innovation in the modern era.Application Development for Embedded Systems

Unable to access external HD

I'm trying to save something on my external HD, but I get this error:

Unable to access "TOSHIBA EXT"

Not authorized to perform operation (polkit authority not available and caller is not uid 0)

I made a snapshot of the error window, but that doesn't go to well either. I would say, this is enough information to help me out. If not, we'll see later.

I use Ubuntu 20.10

convert c++ code to python… please help me T-T

4 Ways CSPM Can Help Improve and Scale Cloud Security

Chances are, it wasn’t long ago that your organization started using cloud computing as an alternative to physical data centers. Even though the cloud is still a relatively recent innovation, it’s already shifted the way organizations function, allowing for IT to go beyond being a cost center and drive business innovation through greater agility and on-demand global reach. 

But, whether you’re just now migrating to the cloud or have been operating in a fully cloud-native way for a while, there’s one thing that needs to be your focus, no matter what: security.

How to Successfully Implement DevOps Techniques Into Your Project

Any innovation should start with a solid business case, and DevOps is not an exception. Why should businesses invest in the changes needed to implement DevOps? In this article, we will answer this question and discuss how to effectively implement DevOps methods in a project.

Setting the Stage for DevOps Implementation

IT technologies have a huge impact on the development of modern businesses. These changes are described in detail in Why Software Is Eating The World by Marc Andreessen. It's not hard to cite a few examples of tech startups that have already made a significant contribution or even changed the entire industry. For this purpose, one can simply look at the radical changes in the retail, transportation, and hospitality industries, which were caused by software innovations from companies such as Amazon, Uber, and Airbnb.

Your Roadmap for the Agile Scaling Framework Landscape

Agile has been a buzzword for decades now, and its popularity has led to a litany of different methodologies and practices, which only get more complicated at scale. It can be daunting to consider scaling Agile, despite the apparent benefits the methodology offers. But, it doesn't need to be! Read on for your guide to the Agile scaling framework landscape and how to choose the best one for your team.

Agile is slowly but surely replacing the Waterfall technique, a time-consuming model that leaves no room for fast changes. As the software development industry moves more quickly, delays caused by the Waterfall model's slow feedback and approval processes created huge risks, sometimes rendering a product obsolete before it even went to market.

Registration Form with confirmation or welcome email after sign up

Hi guys, this is my first post on the forum and I am in need of some help. I am a PHP beginner and I have been trying to come up with a solution to my issue for a while now. I am trying to make a system where a user registers and after the submit button is pressed a welcome message is displayed on the screen along with a confirmation email. This is where I am struggling. I got my registeration system working however integrating this with the confirmation email is very difficult and I don't understand how to structure this at all. I would be very grateful is somebody could help me out. Thank you!
