Securing your application is bloody important. With so much jargon to sift through, it’s easy to get lost, for example there’s SSO, OAuth2, SAML 2.0, OpenID Connect, Federated Identity, 2FA, & MFA. Just to name a few! 😱 In this talk, Anthony will take an in depth look at Federated Identity using OpenID Connect and OAuth2 Framework for ASP. NET Core using Duende IdentityServer (aka IdentityServer 5). You will walk away knowing how to navigate the security options and avoid the madness. 

اگر از objectهایی استفاده می‌کنید که interface مربوط به IDisposable را پیاده سازی کرده اند، حتما از عبارت using استفاده کنید. استفاده از دستور using باعث می‌شود زمانی که دیگر نیازی به object شما نباشد، به صورت خودکار از حافظه حذف شود و در روال جمع آوری زباله (GC) قرار گیرد. این عمل باعث حداقل رسیدن احتمال نشت حافظه در نرم افزار شما می‌شود. برای مثال:

using System;
using System.Text;

class Program
{
    static void Main()
    {
// Use using statement with class that implements Dispose.
using (SystemResource resource = new SystemResource())
{
    Console.WriteLine(1);
}
Console.WriteLine(2);
    }
}

class SystemResource : IDisposable
{
    public void Dispose()
    {
// The implementation of this method not described here.
// ... For now, just report the call.
Console.WriteLine(0);
    }
}

حجم اطلاعات ارسالی به شبکه را به حداقل برسانید. ارسال اطلاعات در شبکه به معنی گذر اطلاعات شما از 7 لایه مختلف شبکه در رایانه شما، گذر از media شبکه، گذر مجدد از 7 لایه شبکه در رایانه مقصد می‌باشد. به این معنی که هرچه اطلاعات بیشتری در شبکه ارسال کنید، سربار بیشتری متوجه سیستم شما خواهد بود. برای رفع این مشکل از فشرده سازهای css و javascript استفاده کنید. این فشرده سازها فواصل خالی، دستورات اضافی و... را از کد شما حذف و حجم آن را به حداقل می‌رسانند.

کم کردن تعداد درخواست‌ها و در نتیجه کم کردن تعداد فایل‌های ارسالی از سرور به کاربر نیز حربه ای در این زمینه می‌باشد.

برای مقایسه فشرده سازها به صورت آنلاین و استفاده از بهترین آنها (متناسب کد شما) می‌توانید از این سایت  استفاده کنید.

امکانات توکاری هم وجود دارد که در زمان اجرای برنامه css و javascript شما را فشرده و تلفیق می‌کند ولی با توجه به اینکه برای سرور در هر مرتبه فراخوانی سربار دارد (حتی در صورت کش کردن) اکیدا توصیه می‌شود از فشرده سازها قبل از اجرای برنامه (Pre-Compressed) به جای فشرده سازهای زمان اجرا (Run-time Compression)استفاده کنید.

Domain-Driven Refactoring - Jimmy Bogard - NDC London 2022

Books, workshops, storming and more, all build up an idealized domain model. All describe great techniques for domain-driven greenfield applications. But what about the code we have? How can we take what's already built, and move it towards a better, more cohesive design?
In this session, we'll look at anemic, procedural, boring code and examine code smells that can point us in the right direction. We'll also look at standard design patterns for more complex behaviors and models, and how to recognize when (and when not) to apply them. Finally, we'll cover how to safely apply refactoring techniques to achieve our domain-driven model nirvana. 

There are a lot of things to consider when choosing your database. Choose wisely because you’ll be married to that database for a long time. One case study is Amazon Marketplace which started with Oracle and tried to migrate after developing their own database solutions. The migration took somewhere between 5 to 10 years, and they seem to be still partially using Oracle. Though if your company reaches Amazon scale, then you’re probably doing very well. 

In Defense of Lazy Loading

I don’t know how this happened but for the last couple years (at least), whenever I read an author who writes about ORMs, I often see a sentiment like this: “ORMs are fine, just make sure you disable this pesky feature called Lazy Loading”.

It’s like this feature is not even needed and only brings confusion and performance issues to everyone who chooses to use it. Well, as you may guess from the title of this article, I disagree with this point of view completely.
