I’ve always been fascinated by making apps as small as possible, especially in the .NET space. No need to ship any files – or methods – that you don’t need, right? I’ve blogged about optimizations you can make in your Dockerfiles to make your .NET containerized apps small, as well as using the ILLInk.Tasks linker from Mono to “tree trim” your apps to be as small as they can be. Work is on going, but with .NET Core 3.0 preview 6, ILLink.Tasks is no longer supported and instead the Tree Trimming feature is built into .NET Core directly. Here is a .NET Core 3.0 Hello World app. Now I’ll open the csproj and add PublishTrimmed = true. <Project Sdk="Microsoft.NET.Sdk"> <PropertyGroup> <OutputType>Exe</OutputType> <TargetFramework>netcoreapp3.0</TargetFramework> <PublishTrimmed>true</PublishTrimmed> </PropertyGroup></Project> And I will compile and publish it for Win-x64, my chosen target. dotnet publish -r win-x64 -c release Now it’s just 64 files and 28 megs! If your app uses reflection you can let the Tree Trimmer know by telling the project system about your Assembly, or even specific Types or Methods you don’t want trimmed away. <ItemGroup> <TrimmerRootAssembly Include="System.IO.FileSystem" /></ItemGroup> The intent in the future is to have .NET be able to create a single small executable that includes everything you need. In my case I’d get “supersmallapp.exe” with no dependencies. Until then, there’s a cool global utility called Warp. This utility, combined with the .NET Core 3.0 SDK’s now-built-in Tree Trimmer creates a 13 meg single executable that includes everything it needs to run. C:\Users\scott\Desktop\SuperSmallApp>dotnet warpRunning Publish...Running Pack...Saved binary to "SuperSmallApp.exe" And the result is just a 13 meg single EXE ready to...
For the last few years, millions of people worldwide have been using mobile devices as the main source of accessing the internet. For this reason, many industries developed a mobile app for their businesses. During the last few years, the IT industry mainly concentrated on fulfilling the market demand and their businesses were focused on making a market existence. However, they ignored to concentrate on app security, code quality, maintainability, and development costs. Now, this is high time to concentrate on such problems and accept new techniques to enhance quality and reduce risks. In this post, I have come up with the approach of DevOps in mobile app development, its benefits, challenges it faces, and how you can implement it in your app development project. So, let’s get started! What is DevOps? DevOps is an exclusive methodology that highlights effective cooperation among all stakeholders engaged in producing a digital product. It incorporates operation staff members, app developers, and project managers. Although the conventional strategies and approach to software development caused extra development costs, time, and client dissatisfaction, DevOps reduces the gap between operations and development and wins over the challenges related to constant software development. The concept behind DevOps for mobile app development is to support a culture of cooperation between teams that earlier worked individually. DevOps is not solely an approach; it can be mainly considered a state of mind or culture. It causes a shift in the mindset, promotes deeper integration, and enhances cooperation. DevOps brings automation, constant delivery, and agile together so that operation and development teams can be more productive and launch software more dependably...
China’s influence is undoubtedly growing in the United Nations, with four of the 15 specialized agencies of the intergovernmental organization being led by Chinese nationals. Beijing seized the “absence” of the United States, accelerated by the Trump administration’s disdain for the U.N., to extend its tentacles to unexpected places. A plan to set up the first U.N. big data research institute is underway in Hangzhou, Zhejiang Province, China. Officially, it would facilitate U.N. operations by amassing and analyzing huge amounts of data from around the world on sustainable development goals (SDGs) to tackle global issues such as starvation and climate change. One cause for concern is that Chinese researchers are expressing the need for data in order to analyze human behavior. The United States, which is wary of any data leaks to China, is raising alarms against the plan. In an October 7, 2020, article in , Hudson Institute fellow Claudia Rosett warned that the plan would enable China to collect data from U.N. member states and set the standards for data collection. “[T]he U.N. badge of legitimacy would make it easier for Beijing to secure flows of data from member states, influence U.N. standards and norms for such data collection, shape the results, feed them into the U.N. system — and project the Chinese Communist Party’s techno-tyranny around the world,” Rosett wrote. The seat of the Undersecretary-General for the United Nations Economic and Social Council (ECOSOC), which promotes the SDGs, has been occupied solely by Chinese nationals since 2007. Incumbent Liu Zhenmin is a former diplomat who has also served as Vice Minister for Foreign Affairs. Secretary-General of...
Hello friends! This tutorial will teach you how to build a local pentesting lab on your Linux machine which will enable you to easily install common web applications so you can practice locating and exploiting their known vulnerabilities (or discover new ones!). In particular, this is an excellent way to learn how to hack WordPress, Joomla, and Dupral plus many more! Basically it’s the same idea as building an intentionally vulnerable virtual machine to practice hacking against, except strictly focuses on the most common web applications. The set up is essentially the same for Windows, although the locations of the folders might be different. This is the only complete and accurate tutorial online that demonstrates: How to install XAMPP How to install WordPress locally on XAMPP How to fix pesky error warnings How to change themes without knowing ftp username/password Step 1: Download XAMPP Step 2: After downloading, navigate to your download folder and double click the XAMPP ‘installer.run’ file. This will install XAMPP onto your system. At the end of the installation, make sure the ‘run XAMPP now’ tick box is checked and click ‘finish’. Step 3: On your XAMPP interface, click ‘manage servers’ then click ‘start all’. Step 4: Now it’s time to download and install an old version of wordpress so I can practice exploiting it’s known vulnerabilities. Click the link below and download the version of wordpress you’d like to practice exploiting. In this tutorial, I am installing wordpress 3.1.3 Step 5: After Downloading, Extract the Zip File into /Opt/Lampp/Htdocs. Step 6: In your browser, navigate to ‘localhost/dashboard and click ‘phpMyAdmin’ in the menu bar...
In this article we will be building a very simple monitor that allows to observe some OS parameters, such as free memory available. In this article we will be using the NodeJS, Angular 4 and Chart.js, so ensure you have node and Angular studio IDE installed. To create our development server we will be using vagrant, so check here for instructions to install vagrant on your operating system. We will be creating two code repos, the first is a node application that will monitor the OS parameters and sends it via websocket to the second app which is an Angular 4 application, the Angular app will utilize Chart.js to represent the server status graphically. Server App Let’s create our server app, by running the following commands in our terminal We want our server to run Ubuntu 16.04, have a static IP address 192.168.50.4 and have NodeJS installed, so replace the content of Vagrantfile with and create a provisioning script named bootstrap.sh with the content In the script above, we first update the apt repository and then we install NodeJS from a private PPA, install build-essential which is required by some NodeJS modules and install forever which helps us keep a node script running forever. No we start the vagrant server with th command: Lets create a package.json file with the content below in our duneserver directory Our package.json contains 3 dependencies, os-monitor–a very simple monitor for the built-in os module in Node.js, nodemon–monitor for any changes in your node.js application and automatically restart the server – perfect for development, and socket.io–enables real-time bidirectional event-based communication. Let us create our...
