Wat doet een Back-end ontwikkelaar?
Bron: coursera , LinkedIn Talent Solutions , Francesco Lelli , Micheal PageBijna elk bedrijf heeft een website, of maakt gebruik van software en IT-systemen. Backend-ontwikkeling helpt deze systemen te laten werken. De verantwoordelijkheden van backend-ontwikkelaars omvatten het maken, onderhouden, testen en debuggen van de volledige back-end van een applicatie of systeem. Dit omvat de kernapplicatielogica, databases, gegevens- en applicatie-integratie, API en andere processen die achter de schermen plaatsvinden. Een hoogopgeleide back-end ontwikkelaar is een programmeur die weet hoe hij gebruikersbehoeften moet analyseren om een positieve gebruikerservaring te garanderen. Wat is back-end development? Back-end ontwikkeling betekent werken aan server-side software, die zich richt op alles wat je niet kunt zien op een website. Back-end-ontwikkelaars zorgen ervoor dat de website correct werkt, met de…

Eclipse Project
Reference: Eclipse Projects page About the Eclipse Project The Eclipse Project is an open source project of eclipse.org, overseen by a Project Management Committee (PMC) and project leaders. The work is done in subprojects working against Git repositories. The Eclipse Project Charter describes the organization of the project, roles and responsibilities of the participants, and top level development process for the project. The JDT and PDE are plug-in tools for the Eclipse Platform. Together, these three pieces form the Eclipse SDK download, a complete development environment for Eclipse-based tools, and for developing Eclipse itself.

How to Develop and Test a Site Using Mobile-First Design
Source: The ManifestAs more users primarily access the web via mobile devices year over year, web design should account for this shift in browsing behavior. Capture a more expansive audience by adopting the mobile-first method using cutting-edge tools and best practice techniques. The number of users with mobile phones worldwide is expected to pass 5 billion by the end of 2019. Subsequently, 52.2% of all global internet traffic was generated through mobile devices— and those numbers are only expected to rise. Along with the growth of mobile marketing, a consequence of this dramatic shift is the importance of embracing mobile-first website design. The value of having a mobile-first website cannot be overstated. When done right,…

PHP Types:: Boolean
Booleans ¶ This is the simplest type. A bool expresses a truth value. It can be either TRUE or FALSE. Syntax ¶ To specify a bool literal, use the constants TRUE or FALSE. Both are case-insensitive. Typically, the result of an operator which returns a bool value is passed on to a control structure. Converting to boolean ¶ To explicitly convert a value to bool, use the (bool) or (boolean) casts. However, in most cases the cast is unnecessary, since a value will be automatically converted if an operator, function or control structure requires a bool argument. See also Type Juggling. When converting to bool, the following values are considered FALSE: the boolean FALSE itself the integers 0 and -0 (zero) the floats 0.0 and -0.0 (zero) the empty string, and the string “0” an array with zero elements the special type NULL (including unset variables) SimpleXML objects created from empty…

When Facing the Unknown, Agility is Your Superpower
Source: CIO UKIn March, as the number of coronavirus infections grew exponentially across the United States, SkyLakes Medical Center in rural Oregon prepared for an influx of patients. In 48 hours, they renovated and opened an entire floor that had not been used for patient care in years. The city of Buffalo, New York knew its non-emergency and city services hotline was going to be more important than ever. Realizing they needed to field calls while working from home, they routed everything through the University of Buffalo’s managed call system (wow, nice teamwork). If you are a parent, you likely remember the exact moment your child, along with millions of others, was sent home…

Using the Python Interpreter
Source: Python.org The Terms ‘Interactive’ and ‘Shell’ The term “interactive” traces back to the Latin expression “inter agere”. The verb “agere” means amongst other things “to do something” and “to act”, while “inter” denotes the spatial and temporal position to things and events, i.e. “between” or “among” objects, persons, and events. So “inter agere” means “to act between” or “to act among” these. With this in mind, we can say that the interactive shell is between the user and the operating system (e.g. Linux, Unix, Windows or others). Instead of an operating system an interpreter can be used for a programming language like Python as well. The Python interpreter can…

Python Virtualenv
Source: VirtualEnv @@ virtualenv is a tool to create isolated Python environments. Since Python 3.3, a subset of it has been integrated into the standard library under the venv module. The venv module does not offer all features of this library, to name just a few more prominent: The basic problem being addressed is one of dependencies and versions, and indirectly permissions. Imagine you have an application that needs version 1 of LibFoo, but another application requires version 2. How can you use both these libraries? If you install everything into your host python (e.g. python3.8) it’s easy to end up in a situation where two packages have conflicting requirements. Or more generally, what if you want to install an…

What is open source?
The term open source refers to something people can modify and share because its design is publicly accessible. Source: opensource.The term originated in the context of software development to designate a specific approach to creating computer programs. Today, however, “open source” designates a broader set of values—what we call “the open source way.” Open source projects, products, or initiatives embrace and celebrate principles of open exchange, collaborative participation, rapid prototyping, transparency, meritocracy, and community-oriented development. What is open source software? Open source software is software with source code that anyone can inspect, modify, and enhance. “Source code” is the part of software that most computer users don’t ever see; it’s the code…

What is Python? Powerful, intuitive programming
Why the Python programming language shines for data science, machine learning, systems automation, web and API development, and more Source: Infoworld.comDating from 1991, the Python programming language was considered a gap-filler, a way to write scripts that “automate the boring stuff” (as one popular book on learning Python put it) or to rapidly prototype applications that will be implemented in other languages. However, over the past few years, Python has emerged as a first-class citizen in modern software development, infrastructure management, and data analysis. It is no longer a back-room utility language, but a major force in web application creation and systems management, and a key driver of the explosion in big…
