Coding Interviews was HARD, until I learned these Patterns dlvr.it/TLtsj1
.NET 6 introduced a new low-level API for reading and writing files without a FileStream. A new type, RandomAccess, provides offset-based APIs for reading and writing files in a thread-safe manner.
Just a friendly reminder: don't put mutable stuff in hashsets or as keys in dictionaries! And be aware of the differences in GetHashCode implementations for classes and records!
💡Golang Tip #69: Manage multiple goroutines with errgroup When we're dealing with a bunch of goroutines, it can be a bit hard to handle errors and make sure they all work together well. You might know sync.WaitGroup, right? But there's a package called errgroup that makes this…
@LondonGarrett That's fair, it's also so much overhead. Each assembly adds runtime and build time overhead. Bigger assemblies are better than lots of small assemblies. This is still true today in the runtime (we re-learned this the hard way when building .NET Core v1)
There are legitimate reasons to split things up: 1. Ability to isolate dependencies like NuGet packages. 2. Distribution (publishing a package). 3. Ability to version components independently. 4. Sharing common code across a code base or solution (s).
In C# there's no way to truly isolate code outside of projects/assemblies. This causes a proliferation of projects in repositories because it's the only easy way to ensure that layering is correct between different components. I wonder if we introduced some other concept at the…

Blogged: Implementing Dijkstra's algorithm for finding the shortest path between two nodes using PriorityQueue in .NET 9 buff.ly/3VuN2xJ In this post I describe Dijkstra's algorithm and show you can implement it with the new PriorityQueue.Remove method in .NET 9 #dotnet
PostgreSQL is enough! 🤔 Cool repo by the way gist.github.com/cpursley/c8fb8…
In interviews, I like to gauge the candidate’s knowledge and interest in certain topics. I found that a good conversational question for backend engineers is this: what happens when the web server crashes while processing a request which has already connected to a database…

Remember...sharding alone doesn't make your database distributed. Sharding solutions rely on a coordinator, whereas distributed databases are built on a shared-nothing architecture. Read more here:: medium.com/@magda7817/sha… Both architectures have their merits. Understanding…
Do you know that several weeks ago @stephentoub added 'ConfigureAwait' overload that takes 'ConfigureAwaitOptions'? Now in .net8 you can control a bit more stuff, like 'ForceYielding'. Here is the link to the PR with the change: github.com/dotnet/runtime…
.NET 8's dependency injection container will support "keyed services". A long-requested feature that has finally landed. This is useful when type alone isn't enough to determine the right implementation. #dotnet
