Keyboard sound is distracting a lot, cant focus on what you saying

[@codeheim]

Thanks. Have reduced the click volume in the newer videos.

[@Manwithnoname838]

Remove it, has no value

[@MAC0071234]

Wow! When I read your comment at the start of the video, I was like "oh the keyboard is gonna be like a mechanical keyboard", but I definitely wasn't expecting THAT. LMAO. Why? Just why did you add that insane sound effect @codeheim? LOLZ.

[@Leeway4434]

it is especially distracting when the audio changes speeds, thus the frequency of the keyboard clicks also change

[@user-fx5li1cy5t]

you've explained the workerpool concept very well! Thank you!

[@codeheim]

Thank you!

[@brycehenderson1187]

You may not see this but I was to say that this video has excellent material! Perfect primer and perfect level of detail to allow for real adaptation to projects. Thank you!

[@codeheim]

Wow, thank you! Glad it was helpful.

[@treeduck999]

Is typewriter not a keyboard 😂 great material anyway! Thanks

[@codeheim]

Thanks 😅 In the new videos, I have tuned down the volume of the keys

[@marckula]

content is good but the key clicks (in stereo ;) ) are distracting - maybe dial down the keyclick volume

[@codeheim]

Noted!

[@BrenoAlmeida]

Best content for golang. Love this channel. Thank you!

[@codeheim]

Glad you enjoy it! Much appreciated!

[@marvinlnnx]

Thank you, great job and very good explained, appreciated !

[@codeheim]

Glad you enjoyed it!

[@spartainaxe6666]

I am simply in aw!!! Explanation was so simple to understand

[@codeheim]

Glad to hear that! And it was very encouraging

[@user-iy7rm7dt8x]

Great! It is very good. Thank you very much!!!

[@codeheim]

Glad you liked it

[@krisiasty]

@codeheim just curious: since you want to process at most 5 tasks concurrently, why the channel size is based on the number of tasks? Also, if you start workers before adding them to the WaitGroup, and for some reason they finish quickly enough, wg.Done will be called before wg.Add, right? Shouldn't you call wg.Add before spawning workers?

[@codeheim]

In the real scenario, the channel size could be based on your analysis or equal to the number of cores. You are right about Wait group Add and Done.

[@codeheim]

Thank you!

[@m.e10150]

Thank you very much

[@dirty-kebab]

Very nice spacing between concepts and sentences. Great animation, clear design. But that keyboard is super sharp. Maybe try Red or Brown keys, they're softer to hear!

[@codeheim]

Thank you! Noted!

[@sakibhasandev]

Good Asmr bro. and nice video

[@codeheim]

Glad you enjoyed

[@Asswipe69]

You are clicking into my soul But still a great video

[@therelatableladka]

Sir, By any chance that you are the one that narrate space television videos ? and do you use a typewriter. Man I'm dying 😂😂 By the way great content !! Thankyou ❤️

[@codeheim]

Glad you liked it! The voice is AI generated. The typewriter sound is also computer generated.

[@kartikrajput2131]

Love the content of this channel

[@codeheim]

Glad you love it!

[@Jarek.]

5:12 shouldn't you do wg.Add() before starting the workers? Ie. before line 42

[@codeheim]

Yes, you are right. It is a mistake

[@bzeeeio]

I understand it is just an example and error handling is not implemented, but there are a few key points to consider: (1) Ensure that wg.Done() is called reliably by using defer. (2) Following Go naming conventions is a small issue, but it is important. (3) Closing tasksChan before all tasks are processed might lead to deadlocks." This version ensures proper grammar and clarity. ... package main import ( "fmt" "sync" "time" ) // Task definition type Task struct { ID int } func (t *Task) Process() error { fmt.Printf("Processing Task ID: %d ", t.ID) time.Sleep(2 * time.Second) return nil } type WorkerPool struct { Tasks []Task Concurrency int tasksChan chan Task wg sync.WaitGroup } func (wp *WorkerPool) worker() { for task := range wp.tasksChan { if err := task.Process(); err != nil { fmt.Printf("Error processing task ID %d: %v ", task.ID, err) } wp.wg.Done() } } func (wp *WorkerPool) Run() { if wp.Concurrency

[@codeheim]

Thank you! I guess due to the deadlines I missed these points. I will keep them in mind.

[@nordeenhasan6030]

alot of thanks for this vedios

[@squ34ky]

The panned keyboard sounds are a bit much.

[@codeheim]

Noted!

[@TheBigWazowski]

If you’re having to manually schedule tasks for goroutines, doesn’t that kind of defeat half of their purpose

[@codeheim]

You are right. This is just an example. Can be used in various ways.

[@omarashraf4493]

are these red switches? and great video btw

[@codeheim]

This is the only video where I tried key sound. Many folks did not like it. Unfortunately, there is no way in KZbin to change the audio track.

[@GauravSingh-hh8bw]

Bro using rusty mechanical keyboard

[@maxwebstudio]

Nice stereo recording.

[@codeheim]

Thanks!

[@maxwebstudio]

​Nice video also btw 😅 ​@@codeheim

[@base_chain_volume]

bro is typing using suppressed ak47

[@jmatya]

those buttons are ripping the ears off, man..

[@codeheim]

Sorry for that. This is the only video where I tried key sound. Many folks did not like it. Unfortunately, there is no way in KZbin to change the audio track.

[@yeir7cnf]

the keyboard sounds are EXTREMELY annoying

[@codeheim]

It happened only in this video. Please enjoy other videos.

[@NestiGX]

Have you thought about muting keyboard? Quite annoying in my opinion.

[@codeheim]

Yes, in the new videos I have tuned down the volume. Unfortunately, there is no way to alter the existing video.

[@user-pu8qf1wv5h]

plz remove the keyboard sound.

[@codeheim]

Can not change the audio in the existing video. :(

[@sefatanam]

WTFFFFFFFF fuyk the keyboard sound

[@timebroua]

Sorry buy your keyboard sounds forced me to quit from video playback

[@codeheim]

I am sorry about that. I have reduced the volume of the clicks in the newer videos. But there is no option to alter the audio in the existing video.

[@netwurst]

The keyboard sound is so annoying that I quit watching this video before the end. Pity because the content seemed interesting.

[@codeheim]

This is the only video I tried with the keyboard sound. Unfortunately, I can not change the audio of the existing video. Please check other videos on the channel

[@For_M.]

I liked your keyboard sound similar to IBM PS/2 keyboard I am not sure regarding title of episode looks like barrier en.wikipedia.org/wiki/Barrier_(computer_science)

[@codeheim]

It is somewhat different. Barrier is for stoping the execution, but worker pool also defines how many goroutines can run at a time. Thanks. you are the first one who liked the keyboard sound.

[@user-ts8rf2fo3j]

Pls no typing sound x)

[@codeheim]

Yes, in the new videos I have tuned down the volume. Unfortunately, there is no way to alter the existing video.
