Red Hat Launches CodeReady Workspaces Kubernetes IDE

The First Kubernetes-Native Developer Environment
From a newly introduced technology to a widely relied upon platform in just a few years, Kubernetes has become an integral part of many organization’s cloud-native solutions - including container-based development environments.
The challenge with building and deploying applications in any Kubernetes distribution is that it’s difficult for a developer to set up a Kubernetes environment that enables fast, iterative development cycles. As a result, some development teams fall back to using containers on their laptops and only seeing how things run in Kubernetes after they’ve merged code back to the origin code repository and triggered a continuous integration (CI) job.
This is problematic as Kubernetes has unique execution behaviors that might necessitate code changes or optimizations. Waiting to do these until after code is merged back to master is inefficient and can introduce problems in the master branch that affect other developers.
Red Hat CodeReady Workspaces is the industry’s first Kubernetes-native integrated development environment (IDE). It makes it easy for developers to have a fast, “locally hosted-style” development experience directly inside Kubernetes and helps development teams avoid the “it works on my machine” problem.

TensorFlow.js: machine learning for the web and beyond
If machine learning and ML models are to pervade all of our applications and systems, then they’d better go to where the applications are rather than the other way round. Increasingly, that means JavaScript – both in the browser and on the server.
TensorFlow.js brings TensorFlow and Keras to the the JavaScript ecosystem, supporting both Node.js and browser-based applications. As well as programmer accessibility and ease of integration, running on-device means that in many cases user data never has to leave the device.

Interviewing tips for junior engineer
Make sure to highlight any interesting project you worked on, technical or otherwise. Recruiters love discussing actual accomplishment. Back when I started, I had a few open source projects and articles written in technical magazines that I put on my resume. Nowadays, that would be a GitHub profile with personal (or professional, if you're lucky) projects. You don't need to rewrite the Linux kernel, but if you can publish a handful of tools you developed over the years, it'll help validate your credentials. Just don't go fork fancy projects to pad your GitHub profile, it won't fool anyone (I know, it sounds silly, but I see that all too often).
Another thing recruiters love is Hackerrank, a coding challenge website used by companies to verify the programming skills of prospective candidates. It's very likely US companies will send you some sort of coding challenge as part of the interview process (we even do it before talking to candidates nowadays). My advise is to spend a few weekends building a profile on Hackerrank and getting used to the type of puzzle they ask for. This is similar to what the GAFA ask for in technical interviews ("quicksort on a whiteboard" type of questions).
At the end of the day, I expect a junior engineer to be smart and excited about technology, if not somewhat easily distracted. Those are good qualities to show during an interview and on your resume.

Modify the enemy sprite’s animation
After we have finished creating our first animated enemy sprite in the previous chapter we will need to further modify that animation class because I have found numerous shortages in the previous program. In the previous program 1) We only create a single counter to handle the sprite animation for all five enemy objects which is simply unrealistic because during the game not every enemy will move to the same frame on the sprite sheet due to the change of the direction of that enemy. 2) There is no adjustment on the image’s transition speed at all, we need to slow down the image transition process so the image will not change too fast.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
