i’ve been doing c++ and perf optimisations for almost 3 decades and i find this guy highly annoying. overly dramatic unpleasant person

this talk is amazing, I'm familiar with all these things but the way he explains is amazingly simple and clear

21:33

amazing talk, sad that probably I will never use this knowledge in my job :|

And the industry as a whole is still making excuses to stick with OO. Shame.

Here from Unity Learn understanding data oriented design. So glad they shared this link. Thank you for all the amazing things that I learned today!

But what about the RAM usage ? although program size shrinks but SRAM is very limited in MCUs . I am eager to know C++ performance on that part . Will be thankful if anyone explains !

😄

Any books that complement this type of knowledge for an average programmer?

"That's what we like to see: 16 times as much CPU power and we're getting results 10% faster than before. Outstanding." LMAO

They always say "what if hardware changes" when cacheline has been 64 bytes since >>2003<<. And if hardware changes it'll be FASTER than what you wrote it on so it won't matter. Its a completely fallacious argument. If you want to ignore the hardware fine. You're just not an engineer. You can't be a doctor and ignore the patients body to simplify your work. You can throw the same pills at everyone but some of those patients are gonna end up corpses.

Why by doubling the threads (@ 8:01) no the performance drops? Context switching?

1:08:15 - In fact, OO design is almost invariably harder to read and maintain than _any_ other paradigm I've come across. It would be nice if people would actually think about what readability means instead of just assuming the Object-is-God dogma is true without it ever being demonstrated.

None of this works in Go because GO shits bounds checks all over the pow10 table.

A lot covered , perfect point for directions on where to put your focus for optimization.

Absolutely fascinating. Helped me to connect the dots and fill in the gaps. I understand the relationship between hardware and software much better now.

wow these lectures are really good

Who can maintain their peace listening to this guy? Why is he so wound up? I will have to find some kind of written version of this lesson.

a nie dało sie tego bardziej po polsku, nie troluje ale wygladało by to bardziej profesjonalnie, co do fearless w nokii to wszystko zalezy od czlowieka czasem można otwarcie mówic a czasem lepiej sie nie odzywać bo będą problemy.

how abt the fact that an array needs a contiguous/continuous range or set of mem addresses only to fit in. So if i define an arr of size n, anything smaller than the n block in the mem is not being used to allocate space for the arr, leading to fragmentation of the mem. but i believe the runtime is more important than the mem fragmentation always right?

by heap based binary search tree at 25:53 is this the heap data structure or heap memory?

I can't help but think, Scott, are you angry? There's this sort of... 'bitterness' emanating from his facial expressions and tone of voice. Like he's just incredibly pissed off at the whole industry and everything it stands for. Which he might be for all I know, but still. (also word choice? that "pathetic" remark towards the audience was a little much 20:40) This talk is important, informative and it doesn't beat around the bush. It gets to the point, which I like. But man, I feel like it could have been so much better if he just spoke in a more positive tone. It's almost like he's berating all of us rather than teaching. The first half of the talk is definitely the worst in this regard, it gets better near the end and especially the questions segment is actually fine, so I'm not really sure why he speaks in this way.

Andrei Alexandrescu Reps "D" Perfectly.. he captures and expounds the essance of "OurCodes" in a profoundly delightful manner.

Finally, a talk with excellent speed

Love his serial killer hair.

Scott Myers of Myers Singleton, Hi Hello 👋...

Absolutely fantastic presentation! I work on embedded satellite systems with very stringent requirements and we have managed to improve performance by a lot with just advice from this video. Brilliant

Very informative snd a good starting point ( with reference material for further learning included )

surprised there's not a bunch of assembly programmers in the comments looking down their noses at the high-level programmers lol

1:15:25 with cpus faster than memory, it is more important to make good use of MEMORY (not cpus)

5:00 the lowercasePee uppercasePee code is not optimized for magazines ... its optimized for idiots (by trolls). but its equally idiotic to still use this hard-to-read code in a presentation

I already knew what was his side when he put "C++ vs C", naturally everybody would put C first, for obvious reasons.

Kudos to camera man and editor for a presentation which has all slides and laser points in it! Finally someone who managed to do this properly!

Great talk and learned something new, and first time seen Scott, what a brilliant mind.

incredible talk!

that db guy was a jerk.

The falsehood and disparity of his comparisons reinforced my belief that C is faster than C++ and superior for embedded development.

This guy is fkn hilarious and super smart.

Thanks Nokia for your generous sharing.

great! got deeper understanding of cpu.

People seem to hate his haircut but I think it suits him really well.

my brain hurts

If you have constrained time to make a speech and have lot to talk about. Instead of speaking faster, speak at normal speed but cut out all the excess time-wasting memes and audience polls from your speech.

Odpadłem ...bo mój angielski jest bardziej mój niż angielski ;-)

Always, some thing more to learn from Scott Meyers! Thanks!

Enlightenment! Love it.

Can i get this video in english as well
