What is .git folder and why is it hidden?
Git is currently the most popular version control system. A version control system records the changes made to our project codebase in a special kind of file system-based database. In Git, this database is known as a repository and its structure is inspired by the Linux file system. The repository maintains a history of the changes to our codebase.The .git folder contains all information that is necessary for the project and all information relating commits, remote repository address, etc. It also contains a log that stores the commit history. This log can help you to roll back to the desired ...
Read MoreRust programming language – Getting Started
The first part of getting hands-on experience with Rust is installing Rust. In order to install Rust, we need a Rust installer.Rustup is a version management tool and also an installer that helps in installing Rust in your local machine.If you’re running Linux, macOS, or another Unix-like OS, then we simply need to run the following command in the terminal −curl --proto ‘=https’ --tlsv1.2 -sSf https://sh.rustup.rs | shThe above command will install Rust on your local machine.If you are on Windows, then you can download the .exe file from this link rustup-init.exeKeeping Rust UpdatedThough Rust is updated frequently, but you ...
Read MoreWhy is Rust Programming language loved so much?
Being voted as the most loved language for four consecutive years, Rust has come a long way.Originally designed as a low-level language, best suited for embedded, systems and critical performance code, it has gained a lot of traction and not stopping yet.Rust also has found its way in web developments and also provides a great opportunity for game developers.So, why is Rust so much loved? Let’s explore some of the reasons why it is so popular and loved.Fearless ConcurrencyConcurrency and parallelism have become more significant in today’s scenario. The number of cores is increasing in computers to support concurrency, but ...
Read MoreDownsides of Rust Programming Language
Every programming language has some downsides attached to it, it’s not all roses when it comes to Rust as well. Some of the noticeable downsides of Rust programming language are highlighted here −Compile TimeYes, compile time. Rust is fast, no doubt. But when it comes to compiling code, then it’s a bit slower as compared to its peer languages. The reason for its slow compile time is that its “unit of compilation” is not an individual file, it’s instead a whole package (known as a crate). Crates in Rust can include multiple modules, thus they can be large units of ...
Read MoreRust Programming Language – Big Features
Rust packs in plenty of features that you can use to build highly scalable and memory‑safe applications and software. But some of these features are overarching features of the language.Here are some of the big features of Rust programming language −PerformanceWe know that the speed of the CPU is fixed, thus for any software to run faster, it needs to do less. To achieve this, Rust pushes the severe burden of its high-level features onto the compiler. Also, it doesn’t need a garbage collectorto ensure the safety.Rust’s object methods are always dispatched statically, unless one specifies that dynamic dispatch is ...
Read MoreRust programming language – Applications
Rust is a multi-paradigm language that can be used in many areas of development. It serves the system programming as the main domain, which these days can even include the web browsers and other software, even if they are user interface ones.That being said, let’s look at the areas of application where Rust programming language shines.Application ExtendingRust has in-built extensions for different commonly used languages like C++, Python and Java. These extensions make it much easier to extend any application code to Rust and hence allowing the developers to make use of Rust’s memory safety and other features which make ...
Read MoreHow is Rust programming language used?
Rust has been adopted by large technology leaders and even startups.Rust just completed a decade and it can be fairly said that it has proven its ability to build powerful, reliable software. Recently it entered the Top 20 popular programming languages in the world.Some of the large technology leaders that have adopted Rust are as follows −Amazon Web Services (AWS) uses rust for performance-sensitive components of services mainly EC2, S3 and Lambda. Also, they sponsored the development of the language.Discord uses Rust in both the client-side and the server-side, mainly to achieve scalability for millions of concurrent users and keep ...
Read MoreHow can Tensorflow be used to download flower dataset into the environment?
The flower dataset can be downloaded using a google API that basically links to the flower dataset. The ‘get_file’ method can be used to pass the API as a parameter. Once this is done, the data gets downloaded into the environment.Read More: What is TensorFlow and how Keras work with TensorFlow to create Neural Networks?We will be using the flowers dataset, which contains images of several thousands of flowers. It contains 5 sub-directories, and there is one sub-directory for every class. We are using the Google Colaboratory to run the below code. Google Colab or Colaboratory helps run Python code ...

Suppose we have a XML file as shown below. Gambardella, Matthew XML Developer's Guide Computer 44.95 2000-10-01 An in-depth look at creating applications with XML. We need to add a new node. So we will first load the XML file and then operate on it as shown below.The below command will save the XML file to the variable.$xmlfile = [XML](Get-Content C:\Temp\SampleXML.xml)The below command will create a new XML element$newelement = $xmlfile.CreateElement("book")Once the element is created we need ...
Read MoreHow to run Invoke-Command in PowerShell Workflow?
To run Invoke-Command in PowerShell Workflow we need to use the InlineScript block because Invoke-Command is not supported directly in the workflow. The below example is without using the InlineScript block we get an error.ExampleWorkflow TestInvokeCommand{ Invoke-Command -ComputerName LabMachine2k16 -ScriptBlock{ Get-Service WINRM } }Output −At line:2 char:5 + Invoke-Command -ComputerName LabMachine2k16 -ScriptBlock{ + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Cannot call the 'Invoke-Command' command. Other commands from this module have been packaged as workflow activities, but this command was specifically excluded. This is likely because the command requires an interactive Windows PowerShell session, or has behavior not suited ...
