Rust Programming Fundamentals
Ryan Dahl, the creator of Node.js, is currently working on Deno, a new runtime for JavaScript and TypeScript, built using V8, TypeScript, and Rust. A 30-minute overview talk.
To reduce allocations and memory usage when serializing Json.NET 8.0 adds a new IArrayPool interface. Json.NET is already very lean when it comes to allocations, working with raw characters on array buffers instead of allocated strings, but those buffers can easily grow large, and a new buffer is created each time JSON is read or written. IArrayPool allows array buffers to be reused, similar to connection pooling with a database, or thread pooling in .NET.
Issues Fixed in 15.9.21
- Fixed a bug where the .NET Profiling tools couldn't be installed on non-enterprise versions of Visual Studio 2017 when using an offline installer.
- Fixed C++ compiler bug where a static_cast in a decltype would evaluate incorrectly. To minimize disruptions to existing codebases, in VS2017 this fix takes effect when the (newly added) /d1decltypeIdentityConversion switch is thrown.
- New Spectre mitigation options in C++ compiler: /Qspectre-load & /Qspectre-load-cf for speculative load hardening.
Security Advisory Notices
When used as a declaration modifier, the new keyword explicitly hides a member that is inherited from a base class. When you hide an inherited member, the derived version of the member replaces the base class version. Although you can hide members without using the new modifier, you get a compiler warning. If you use new to explicitly hide a member, it suppresses this warning.
Welcome to the April 2019 release of Visual Studio Code. During April, we were busy with the Preview release of the Remote Development extensions. These extensions let you work with VS Code over SSH on a remote machine or VM, in Windows Subsystem for Linux (WSL), or inside a Docker container.
It comes with full support for .NET Core 2.0, adds MSTest, various NuGet improvements, a new debugger tool window for visualizing Parallel Stacks and marking of instances, new refactorings and more. And with ReSharper 2017.2 now released, we’ve updated the ReSharper version powering Rider, too. Which brings improved support for C# 7.0, initial support for C# 7.1, new code inspections, navigation improvements, and so on. Let’s look at a few highlights!
- Reduce start up time by loading finished code first models from a persistent cache
- Fluent API to define indexes
- DbFunctions.Like() to enable writing LINQ queries that translate to LIKE in SQL
- Migrate.exe should support -script option
- EF6 does not work with primary key from sequence
- Update error numbers for SQL Azure Execution Strategy
- Bug: Retrying queries or SQL commands fails with “The SqlParameter is already contained by another SqlParameterCollection”
- Bug: Evaluation of DbQuery.ToString() frequently times out in the debugger
Microbenchmark testing Python, Numba, Mojo, Dart, C/gcc, Rust, Go, JavaScript, C#, Java, Kotlin, Pascal, Ruby, Haskell performance in Mandelbrot set generation
Benchmarking several languages/tools with Mandelbrot set generation. 1-to-1 translation of code from one language to another. No SIMD, no multithreading (except prange() trick with Numba), no tricks (e.g. skipping sqrt), a bare minimum of language specific adjustments to make the code nicer while keeping all loops and operations in place.
As you might have wondered, if an event is a kind of delegate, why do we need an event where a delegate can fulfil the purpose?
