مقایسه کارآیی خروجی زبان‌های مختلف برنامه نویسی

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.

بررسی چالش‌های استفاده از UTC و TimeZones در برنامه‌های تحت وب مبتنی‌بر ‪.NET

Using UTC in Applications

Using UTC dates for data is a pretty common and necessary practice but it definitely adds some complexity when managing dates as you always have to remember to properly adjust dates. For display purposes this is pretty straight forward, but for query operations there’s a bit of mental overhead to ensure your date math adds up properly.

No easy solutions, but I hope this post and some of the helpers make life a little easier for you – I know they do for me.

انتشار WinJS 4.0
In addition to Windows 10, WinJS 4.0 supports the latest versions of all your favorite browsers, including the new Microsoft Edge. We realize that many developers are more familiar with, and may prefer to use, other frameworks for various parts of their app. We have checked in wrappers for AngularJS, KnockoutJS, and ReactJS to our GitHub project. You can now create Windows or web applications using other web frameworks, while still having access to the rich set of controls that WinJS provides.

8 روش که باعث نشت حافظه در دات نت میشود

Any experienced .NET developer knows that even though .NET applications have a garbage collector, memory leaks occur all the time. It’s not that the garbage collector has bugs, it’s just that there are ways we can (easily) cause memory leaks in a managed language.

Memory leaks are sneakily bad creatures. It’s easy to ignore them for a very long time, while they slowly destroy the application. With memory leaks, your memory consumption grows, creating GC pressure and performance problems. Finally, the program will just crash on an out-of-memory exception.

In this article, we will go over the most common reasons for memory leaks in .NET programs. All examples are in C#, but they are relevant to other languages.
