Job Opportunities for Skilled C++ Candidates

This content brought to you by Andrew Dominik from qualityguestpost

C++ is an extension of C language. C++ programming language is complex, but strongly preferred in today’s IT sector. You will come across some part of its codebase in generally every system or program. It is the first language developers interested in programming start with. You can learn it with ease as it is purely a concept-based language. The syntax is uncomplicated, so you can easily replicate its writing. Its use is regarded as a safe language due to its valuable features and security. People learn C++ because of several reasons –

Running Kubernetes on VMware: Challenges and Solutions

In August, 2019, VMware vSphere announced they are going Kubernetes-native. This means that integrated VMware and Kubernetes becomes a reality for all vSphere users. Despite all the benefits this integration promises, running Kubernetes on VMware is not exempt from challenges. This article presents an overview of running Kubernetes on VMware and the challenges it presents.

The demand for cloud-native application development is increasing on a daily basis. Cloud-native apps can provide benefits that traditional apps can’t, including high availability, automatic resource provisioning, and auto-scaling. These applications also help organizations and developers maintain their competitive edge.

In this article, you will learn best practices for cloud-native application development on Azure, including tooling for creating and deploying your first Azure-native application.

C++ Is Faster and Safer Than Rust: Benchmarked by Yandex

Author: Roman Proskuryakov

Spoiler: C++ is not faster or slower – that’s not the point, actually. This article continues our good tradition of busting myths about the Rust language shared by some big-name Russian companies.

The previous article of this series is titled “Go is faster than Rust: benchmarked by Mail.Ru (RU)“. Not so long ago, I tried to lure my coworker, a C-programmer from another department, to Rust. But I failed because – I’m quoting him:

In 2019, I was at the C++ CoreHard conference, where I attended Anton @antoshkka Polukhin’s talk about the indispensable C++. According to him, Rust is a young language, and it’s not that fast and even not that safe.

Anton Polukhin is a representative of Russia at the C++ Standardization Committee and an author of several accepted proposals to the C++ standard. He is indeed a prominent figure and authority on everything C++ related. But his talk had a few critical factual errors regarding Rust. Let’s see what they are.

The part of Anton’s presentation (RU) that we are particularly interested in is 13:00 through 22:35 .

Zero, one, two, Freddy’s coming for you

This post continues the series of articles, which can well be called “horrors for developers”. This time it will also touch upon a typical pattern of typos related to the usage of numbers 0, 1, 2. The language you’re writing in doesn’t really matter: it can be C, C++, C#, or Java. If you’re using constants 0, 1, 2 or variables’ names contain these numbers, most likely, Freddie will come to visit you at night. Go on, read and don’t say we didn’t warn you.

A 6 Step Field Guide for Building Machine Learning Projects

Author: Daniel Bourke
Machine learning is broad. The media makes it sound like magic. Reading this article will change that. It will give you an overview of the most common types of problems machine learning can be used for. And at the same time give you a framework to approach your future machine learning proof of concept projects.

First, we’ll clear up some definitions.

How is machine learning, artificial intelligence and data science different?

These three topics can be hard to understand because there are no formal definitions. Even after being a machine learning engineer for over a year, I don’t have a good answer to this question. I’d be suspicious of anyone who claims they do.

To avoid confusion, we’ll keep it simple. For this article, you can consider machine learning the process of finding patterns in data to understand something more or to predict some kind of future event.

The following steps have a bias towards building something and seeing how it works. Learning by doing.

Hunting Down and Fixing Memory Leaks in Java

Author: Bradley Kofi
In the last article, we covered the most basic aspects of what memory leaks are, what causes them and how to eliminate them from your program.

As a preamble, memory leaks happen when the garbage collector (GC) is unable to clear unreferenced objects from working memory. Considering how much of its popularity Java owes to its garbage collector, how can it this be possible? As it turns out, the GC has a few weak spots:

Unreferenced static fields: The GC is unable to clear static fields unless the class that owns it is unloaded, which only happens if the Classloader that called it is garbage collected.

Unclosed system resources: The GC indirectly frees up files since classes like FileInputStream are written such that if an instance is garbage collected, the ‘close()’ method will be called first. This way, unclosed system resources don’t always pose a risk, so a lot of developers tend to look over them.

Most systems have hard limits on how many files can be open at once, and in addition to hard-to-reproduce bugs like different processes being unable to access the file or OS errors, such issues can be quite problematic to debug. They aren’t memory leaks in the exact sense but memory usage does remain high in the time that the stream remains open.

Besides, it’s also worthwhile to remember that class unloading may or may not happen depending on the JVM implementation.

Unclosed connections: Like with unclosed resources, unclosed database or network connections can lead to significant memory use if not unloaded.

Additional reasons memory leaks may occur include having a small heap space, excessive page swapping by the operating system and long delays in garbage collection.

The focus of this article is the various techniques that can be used to hunt down memory leaks once you’ve recognized how memory leaks happen.

Why I’m Using C

Author: Casper Beyer

The front cover of the “C Programming Language” book as I recall it from memory

Why on earth would someone would pick C to start a new project in 2020? Surely there is a newer language with more shiny features that’s better right? Well I can’t speak for other people but I’ll tell you my reasons.

First of all let me preface this by saying that of course this is a biased opinion and the language I pick for something depends on the context it’s going to be used in. For example; I doubt I’ll ever be reaching for C when writing a web service simply because the ecosystem around that domain isn’t great and I’m not itching to write my http framework at this time.

But for games, more specifically cross-platform games C is a clear winner for me because it provides me with exactly the things I’m looking for which is reliability, simplicity and performance.
