یک مدل جذاب کنترل سورس برنامه

A source-control branching model, where developers collaborate on code in a single branch called ‘trunk’ *, resist any pressure to create other long-lived development branches by employing documented techniques. They therefore avoid merge hell, do not break the build, and live happily ever after

با سی شارپ 8 از دست NullReferenceExceptions ها خلاص شوید

A .NET guideline specifies that an application should never throw a NullReferenceException. However, many applications and libraries do. The NullReferenceException is the most common exception happening. That’s why C# 8 tries to get rid of it. With C# 8, reference types are not null be default. This is a big change, and a great feature. However, what about all the legacy code? Can old libraries be used with C# 8 applications, and can C# 7 applications make use of C# 8 libraries?

This article demonstrates how C# 8 allows mixing old and new assemblies.

دقیقا چه اتفاقی برای Parler رخ داد؟

Parler relied on several external services for security; but when those services were yanked away (due to Parler hosting neo-nazi and insurrectionist content), their code took the absence of such services as a reason to approve whatever action the user was trying to take. It’s the equivalent of your house security system letting everyone in if the phone-line goes down. There’s so much more to the Parler hack, from the lack of rate-limiting to the ability for people to pull down 60-70TBs of information from Parler’s AWS hosted storage, which — to add insult to injury, results in a massive egress bill from AWS to Parler, on top of AWS no longer hosting Parler.
