Deep .NET: Let's Talk Parallel Programming with Stephen Toub and Scott Hanselman

[@teraformerr]

more Stepheon Toub content is always a godsend

[@manishmanghwani2071]

Stephen Toub is one of the Gems...you must be super lucky to work under him :)

[@josefromspace]

A humble request for those of us watching on large screen TV’s. Is there chance we can get Stephen to use Visual Studio Dark Theme? This series deserves 4K TV and popcorn. 🍿 Phenomenal episode as always. 👏🏼 Thank you both.

[@dy0mber847]

It's just mindblowing when such experts do the stuff. Thanks❤

[@nocgod]

Leaning back on my couch after a long day... Watching Stephen & Scott on a 77" OLED... You should really avoid these static resources on screen for my sake :)

[@mzg147]

Maybe the background should move just a little bit? :)

[@mohd.tahauddin9001]

I agree with this. Can we have a black background and less static elements please. This will make it more OLED friendly :)

[@theandrewharry]

Another amazing video from Scott and Stephen. Thanks for taking the time to put out this amazing content. Much appreciated 👍

[@mohaarulez]

Amazing insights of how everything works behind the scenes and very well explained. I absolutely love these talks, looking forward to the next one.

[@peteathome2019]

I love that this is "just" a meeting in your work day, and you turned it into a video. This has made me think about some of the great rambles I've had with a co-worker that would have made an excellent video too. I'm taking this as food for thought for how I could capture that

[@JacobSnover]

I have been using a PC for my main device in the living room for years, I don't subscribe to cable and prefer to stream. So YES I def sit back and watch this on my big screen.

[@MichaelKuritzky]

Love this series! Catching up on missed episodes now while feeding my newborn son :)

[@FuzzyNinjaful]

I love this series with Stephen! I'm always looking forward to more! I would absolutely watch an extended "Too Deep .NET" cut

[@CodeWithAnup]

We want more in depth Parallel Programming related videos like this. Another great video.

[@cgonzalez7469]

A joy indeed! Thank you both.

[@Dustyy01]

WE NEED MORE DEEP DOTNET❤

[@deivycode]

Toub is a goat! 🐐 Please keep with this kind of series are amazing, we should start talking about GC, pointers, Marshalls and those low level stuffs!

[@lis2889]

Thanks folks, it was great and knowledgeable to watch! Could you please record dive deep into *GC* video.

[@henrikstornblom]

The Deep Dotnet is the best 💚

[@philritchie9253]

Could you do a session on Expressions particularly those which use generics: how they can be parsed at runtime and manipulated to do dynamic operations.

[@aderitosilvachannel]

Great video! I love how Stephen Toub explains things! Thank you for sharing this knowledge!

[@MatteoGariglio]

Another very interesting discussion. Thanks a lot for providing this kind of "unique" and precious content.

[@dlozanonavas]

It wouls be amazing to have a talk (if isn't out there in the wild already) about benchmarking with .NET Benchmark. Thanks for the knowledge on Parallelism.

[@MatthiXXY]

"So we can write our own very easily". I love this sentence!

[@barrysphone]

Loving these shows, thanks for making them. Something I would be very interested in seeing in a future video would be some discussion of code branches as they relate to the branchpoints that are reported by dotnet test in coverlet opencover xml reports. For example a simple line of C# could report 14 branchpoints with different paths/offsets and it would be great to know how they actually relate to the line of code. That way it could identify what tests are required to cover the missing branches. I remember Stephen showing some different views of the code, eg IL, and maybe there is some way to relate the xml data to the code in Visual Studio or some website.

[@pmnm113]

Thank you both, I am always waiting on what next and watching it more like a movie

[@SaitamaTheLegend]

Thanks Scott and Stephen for these videos! They are really interesting! For the future please talk about these 2 topics: 1 How are Tasks/Threads (especially those doing IO) integrated with the OS. I was asked many times during interviews how are Tasks/Threads working behind the scenes. What happens when an HTTP call is made, or a file operation is performed. I didnt answer this question for a long time because to be honest I thought it's too deep for me to even know or care. I dont want to understand everything about my tools; how they work internally (because my time on Earth is limited and I wanna focus on what I choose to be relevant). As you said in today's video you try to hide the complexities and devs rarely need to know whats under the hood, but this topic still intrigued me. I read a bit about the components of the OS (for both Windows and Linux) that take over the IO work and then resumes it into the framework, but I dont fully understood the entire mechanism and you guys have a nice way to present these complicated things. I am sure I`ll understand it better from you. Not for the interviews but for my own curiosity. 2. How is parallelism and async/await working in Kubernetes. Prallelism and async/await are cool and I use them all the time, but for example in my company the IT department sets all pods to 10 mCPU in Kubernetes (in my current understanding disabling any possible parallelism). In this situation is it worth using async/await in my ASP.NET Web APIs or I`m just adding overhead? Is my Web API able to handle more requests with or without async/await? etc. I dont understand the full effect and I would like to hear your opinion even if it wont be a full episode on this topic.

[@kinsondigital]

Fantastic!! These videos are absolute gold. More more more. . . .

[@NickAskew]

Wow, really nice video. I can't say I could follow it all but the false locking makes sense and after that I spent a lot of time scratching my head ;-)

[@flygonfiasco9751]

Excited for this, thanks to you both!

[@antonzhernosek5552]

Great stuff as always. But I feel like after all of the in-depth talks, the conclusions have eluded me. Most importantly, what's the benefit of using Parallel over spawning a bunch of tasks, or is there any? What kinds of workloads could be optimised with it? I'd love some explanations of how Parallel is integrated into the core library and why it works well for those cases

[@mhDuke]

i feel the same. and i thought to myself perhaps it would be better investment if i learn to write manual parallel code optimized for the case at hand. Especially after learning that Parallel.For would do a lot of work just to figure out how it should do parallelism, and it might not do it right everytime!

[@emmanueladebiyi2109]

Such great content. Thanks Stephen and Scott!

[@andreydeev4342]

Great talk, as all videos with Stephen Toub!

[@JoeIrizarry88]

great as always! Love to hear about low-level optimizations in dotnet apis e.g. minimal apis, json encoding, wire-level and IO

[@neppe4047]

Stephen's laugh is life

[@jpdo4067]

Ok, studying c# for a while, and grasping more and more, "go to definition" in visual studio helps clarifying

[@aoe2dog]

Stephen Toub and Scott Hanselman talking programming .. is like you take something very complicated and they explain it in a understandable way

[@salk52]

What a great video, thanx for sharing all of the information with us

[@mrqbboy]

Awesome stuff. Thanks Guys. I especially liked the last segment.

[@dawiz2k1]

Toub is AWESOME! Great video!

[@SlackwareNVM]

Now that you mention it, Channels would be a really interesting topic. It's something I've used a lot and has been massively helpful for in-memory messaging and such. Edit: A custom, built from scratch, Thread Scheduler would also be really interesting. I know Orleans, for example, sequences the calls to the same grain, but runs in parallel calls to different grains, but I'd love to see how I would go about implementing a scheduler like that. Or maybe a scheduler for the requests on a simple http server.

[@okmarshall]

Great video! What would be your advice for server side parallelism? I work on an Orleans system which handles very heavy data loads with UI interaction. We use Parallel.ForEach a lot but often run into performance issues if we let it use all the processor count. Super fast for single users but it doesn't scale well. Should we just use tasks instead of the parallel library and let it scale as it sees fit?

[@naveenkp7849]

My favorite person at Microsoft.

[@biohaz999]

Wonderful! Thanks for the effort guys! What i want to learn a little bit more is about lowering in the C# compiler, esp how to deal with like DU's compared to TypeScript (Structural vs Nominal Typing) why its different, how they compare and why C# has so a hard time implementing DU's (I know that's pretty academic, but maybe Scott will get Mad's on the show 🤗🤗🤗🤗)

[@TomSayer-j5c]

I love your talks!

[@alwaseem5309]

Thank you for this great session!!

[@DustyBg]

This stuff is gold! Thank you so much!

[@jazzerbyte]

Lots of great information here, thanks!

[@sahilmishra1999]

Got to learn a lot, especially learning to visualize threads Thanks a lot Stephen Toub and Scott Hanselman, I majorly work on Function App(Isolated) so just was curious how these Frameworks actually manage these kind of parallelism, I also looked into the threads for one of the execution its quiet confusing it takes around 40-50 thread per execution. Thanks once again.

[@yufgyug3735]

i really wish there was some literature on these deep topics. its so fun to learn, but very few quality sources to learn from.

[@Bourn77]

great video, one suggestion is to use dark mode in IDE for the sake of my eyes.

[@chrisnuk]

I want an episode of "too deep" because I'm that guy who steps on the treadmill and thinks 3 too easy. Let's try 10..😂 Thank you. That was very interesting. I know I could just read the code, but having Mr Toub tell me his thinking makes it so much more interesting!

[@chrisnuk]

There was an awkward moment at 1:13 when I felt caught out steepling..😅

[@secvbulrep]

Thnks a lot for making us better!

[@leknyzma]

Can we talk about how SIMD comes into play here, in part 2 ?

[@WeihanLi-iHerb]

Like it before watching into it as usual

[@dasokume9411]

We want more of that!

[@briantoogood8928]

That was pretty intense!

[@Meir017]

how about a "Deep Roslyn" where you go into the capabilities of the roslyn compiler?

[@MayanksPage]

Really enjoyed this video!

[@98mosi]

I enjoyed and i so learned

[@Jordan-ln3yc]

Great series 🎉 keep up the good work

[@clashclan4739]

Pls upload videos is 2k 4k quality

[@unitycoder]

any tips about Profiling and those Benchmarks? (for: How to make slow data processing application faster : )

[@gdargdar91]

Stephen Toub has a cool style.

[@TC-xk5rm]

I feel like other youtube tutorials need to point to these videos when covering topics involving an overview of these techniques. It would help create better code from everyone.

[@Lenard-ps1zu]

awesome ❤❤

[@adsfaedaer]

I'd like a deep dive on garbage collection - thanks

[@Miggleness]

I restrict access to the family 65” TV when Stephen Toub KZbin videos drop

[@hoisinholdup]

What's the opposite of nominative determinism because I feel like it should be spelled Stephen Turbo

[@SlackwareNVM]

"Who watches a one hour youtube video?" I watch at 2x speed, but what that really means I can actually go for a 5 hours video.

[@christianschulz4475]

F: for fun with Scott.

[@Dustyy01]

1:03:54 "Thank you for doing that, people on their phone appreciate your work." - Scott to Stephen while he starts Zoomit and me actually being on phone haha😂

[@timur2887]

👍

[@dtienloi]

😍😍😍

[@RomuloMagalhaesAutoTOPO]

Cool

[@AvenDonn]

Stephen Toub reading bedtime stories about .NET performance please

[@ВолодимирШелест-и7ь]

Don't tell about the event to my girlfriend, but I absolutely do this to my teammates 😅

[@alexvanheerden5702]

Sleep Sort

[@GuildOfCalamity]

Dark theme please!

[@sile9tlight687]

Thx a lot! I learned so much new by just watching this video. #DeepDotNet
