海外TECH	DEV Community	Native AOT: The Future of .NET App Development	https://dev.to/bytehide/native-aot-the-future-of-net-app-development-47ha	Native AOT The Future of NET App DevelopmentIn the world of software development performance and efficiency are crucial The NET framework has consistently provided developers with powerful tools to create robust high performance applications One of the recent advancements in NET technology is Native AOT Ahead of Time compilation This article explores Native AOT NET its benefits key components how it works and its various use cases What is Native AOT NET Native AOT NET refers to the process of compiling NET applications ahead of time into native code optimizing their performance at runtime This technique allows applications to run directly on hardware without the need for just in time JIT compilation leading to improved performance and reduced memory usage Benefits of Native AOT NET Performance improvementNative AOT NET offers significant performance improvements by compiling the application code ahead of time This eliminates the need for JIT compilation during runtime reducing the overhead associated with it Startup time reductionAs the code is already compiled to native code the startup time for applications is significantly reduced This is particularly useful for scenarios where quick application startup is essential such as mobile or serverless applications Memory footprint reductionNative AOT NET reduces the memory footprint of applications by avoiding the need to store intermediate compilation artifacts in memory This leads to lower memory consumption and improved performance especially in memory constrained environments Enhanced securityBy compiling code ahead of time Native AOT NET can apply security hardening techniques during the compilation process making applications more resilient to potential attacks Key Components of Native AOT NET CoreRTCoreRT is the runtime library used in Native AOT NET It provides the necessary components for ahead of time compilation such as garbage collection reflection and platform abstractions LLVMLLVM Low Level Virtual Machine is an open source compiler infrastructure used for code optimization in Native AOT NET It helps in generating highly optimized native code for various target platforms RyuJITRyuJIT is the default just in time compiler for NET In Native AOT NET RyuJIT is used during the ahead of time compilation process to generate intermediate code which is later optimized by LLVM How Native AOT NET Works Ahead of time compilationNative AOT NET compiles the application code into native code ahead of time converting CIL Common Intermediate Language code into machine code This process uses CoreRT LLVM and RyuJIT to generate highly optimized native code tailored for the target platform Runtime linkingDuring runtime the native code is linked with the required runtime libraries such as CoreRT to create a complete and executable application This process enables Native AOT NET to achieve optimal performance while maintaining compatibility with existing NET features Comparison with Just In Time JIT CompilationThe primary difference between Native AOT NET and JIT compilation is when the compilation occurs In JIT compilation the application code is compiled into native code during runtime which can introduce some overhead and affect performance On the other hand Native AOT NET compiles the application code ahead of time resulting in faster startup times and improved overall performance While Native AOT NET offers some advantages over JIT compilation it may not always be the best choice for every application JIT compilation can still provide better performance in certain scenarios such as when using dynamic code generation or when the application relies on runtime code optimizations Native AOT NET and Platform CompatibilityNative AOT NET supports various platforms including Windows macOS Linux and mobile platforms like iOS and Android This broad compatibility allows developers to create high performance platform specific applications using familiar NET tools and libraries Native AOT NET Limitations and ConsiderationsWhile Native AOT NET offers numerous benefits there are some limitations and considerations to keep in mind Native AOT NET applications tend to have a larger binary size compared to their JIT compiled counterparts This is due to the inclusion of runtime components and the absence of runtime code generation Some NET features such as dynamic code generation might not work as expected or may require additional configuration when using Native AOT NET Ahead of time compilation can increase the build time of applications especially for large projects How to Get Started with Native AOT NETTo get started with Native AOT NET you can use the NET SDK and its associated tools to create build and deploy your applications Ensure that your project is compatible with Native AOT NET by updating your application s dependencies and configuration files Finally follow the official documentation and guidelines for building and deploying Native AOT NET applications on your target platform Native AOT NET Use CasesNative AOT NET is particularly well suited for the following use cases Mobile applications Native AOT NET can help improve the performance and startup time of mobile applications providing a better user experience on resource constrained devices Serverless applications In serverless environments where quick startup times and low memory usage are crucial Native AOT NET can offer significant benefits Desktop applications Native AOT NET can be used to create high performance platform specific desktop applications that take full advantage of the underlying hardware ConclusionNative AOT NET is an exciting advancement in the NET ecosystem that enables developers to create high performance platform specific applications with reduced startup times and memory usage By understanding the benefits limitations and use cases of Native AOT NET you can make informed decisions about whether it s the right choice for your project	2023-05-03

海外TECH	Engadget	White House proposes 30 percent tax on electricity used for crypto mining	https://www.engadget.com/white-house-proposes-30-percent-tax-on-electricity-used-for-crypto-mining-090342986.html?src=rss	White House proposes percent tax on electricity used for crypto miningThe Biden administration wants to impose a percent tax on the electricity used by cryptocurrency mining operations and it has included the proposal in its budget for the fiscal year of In a blog post on the White House website the administration has formally introduced the Digital Asset Mining Energy or DAME excise tax It explained that it wants to tax cryptomining firms because they aren t paying for the full cost they impose on others which include environmental pollution and high energy prices nbsp Crypto mining has negative spillovers on the environment the White House continued and the pollution it generates falls disproportionately on low income neighborhoods and communities of color It added that the operations often volatile power consumption can raise electricity prices for the people around them and cause service interruptions Further local power companies are taking a risk if they decide to upgrade their equipment to make their service more stable since miners can easily move away to another location even abroad nbsp It s no secret that the process of mining cryptocurrency uses up massive amounts of electricity In April The New York Times published a report detailing the power used by the large scale Bitcoin miners in the US that it had identified Apparently just those operations altogether use the same amount of electricity as three million households in the country The Times explained that most Bitcoin mining took place in China until when the country banned it making the United State the new leader In the US New York Governor Kathy Hochul signed legislation that restricts crypto mining in the state last year Previous reports estimated the electricity consumption related to Bitcoin alone to be more than some countries including Argentina Norway and the Netherlands nbsp As Yahoo News noted there are other industries such as steel manufacturing that also use large amounts of electricity but aren t taxed for their energy consumption In its post the administration said that cryptomining does not generate the local and national economic benefits typically associated with businesses using similar amounts of electricity Critics believe that the government made this proposal to go after and harm an industry it doesn t support A Forbes report also suggested that DAME may not be the best solution for the issue and that taxing the industry s greenhouse gas emissions might be a better alternative That could encourage mining firms not just to minimize energy use but also to find cleaner sources of power It might be difficult to convince the administration to go down that route though In its blog post it said that the environmental impacts of cryptomining exist even when miners use existing clean power Apparently mining operations in communities with hydropower have been observed to reduce the amount of clean power available for use by others That leads to higher prices and to even higher consumption of electricity from non clean sources nbsp If the proposal ever becomes a law the government would impose the excise tax in phases It would start by adding a percent tax on miners electricity use in the first year percent in the second and then percent from the third year onwards nbsp This article originally appeared on Engadget at	2023-05-03 09:03:42
