In this blog we discuss basic concepts surrounding quantum qubits (quantum entanglement, superposition, and decoherence), relate superposition to the โBloch Sphere,โ obtain a random value by measuring a qubit in superposition, and present a Q# quantum number generator (QRNG) that generates random numbers to the console…
It can be challenging to decide on the right strategy for reaching the mobile audience, though. If you decide an app is what you need, the next question is โwhat are my options?โ In general terms, the types of mobile applications you could choose to build can be divided into three groups: vendor-native, cross-platform, and hybrid web.
In this post, we give an overview of the various mobile development strategies on our shortlist for enterprise clients to consider; for example, Xamarin, Flutter, React Native, and Ionic. For each tool, we give a brief introduction and highlight the key advantages and disadvantages found in implementing each mobile development approach.
In this blog, weโll present a simple arithmetic expression parser implemented through an Antlr4 parser generator. It will be able to take in an input string (such as 2+4+-4+-2*10%9*7) to produce the result (-12.0).
You may be thinking, “Great, but whatโs the point?” Well, to answer your question, as simple as this example may seem, the principles involved actually extend to use cases such as DSLs, transpilation, and anything else expressible by grammar rules.
This post has two parts. In part 1, weโll discuss the background components of a parser. In part 2, weโll cover building the demo and running it. If you already understand grammar parsing, you could skip part one.
The last few years have seen a lot of movement to bring applications that don’t require manual intervention from the mainframe to Unix, Linux, Windows servers, or even to the desktop. This concept is commonly known as batch programming, and Spring Batch has been the tool many of us are using to accomplish this. Another trend that is gaining steam is to move from an internally-hosted server to a cloud-hosted system.
In this post, we discuss multiple ways for transferring Spring Batch applications up to the AWS Cloud, including EC2, Docker, Lambda, and others. I concentrate on AWS in this post, but, from my experience in Google Cloud, the same ideas will apply…
Last year I blogged about creating a Lean Mean Vue Machine called Quotes on Demand. The application was a fully-featured CRUD application served from a NodeJS server and had a self-contained VueJS front end. Since then Iโve also added a Python version of the same API.
But wouldn’t it be a nice test to see if that same Vue application could switch over to another API – say, something like a Golang application server?
In this post, we will create a Golang application server that will have 100% parity to an existing NodeJS web application. This will enable an existing VueJS front end to connect to the application with no additional code changes in the user interface code.
