These videos are amazing! Please never stop providing this excellent, concise and practicable information. Thank you 🙏🏻

[TheRealMangoDev]

this series is amazing! Thanks (tbh i never thought i could get this far in osdev but here i am)

[abdooowd]

This is the kind of video I'd love to see in my recommendations. Great work! To be honest, that's the best development series I've ever seen! Thank you.

hey if you're new to cs remember to look at the binary values of 0x20 0x80 etc to understand why the constants are defined like that

[loucantnot]

Thank you for these excelIent videos !
As for the intro, I feel ya as I also like my sugar with coffee and cream x)
(Quoting the Beastie Boy's "Intergalactic" song btw, it's a banger)

Im sure there's a compiler flag to emit header dependency information -MMD iirc, the resultant .d files integrate with make fairly well, although the overhead is probably not worth it when the project is small.

[poleoluline]

You can have gcc -MM to generate header dependencies for each c file and then -include this in your Makefile. No need to parse anything, and make will "know" automagically, . which c files to rebuild after change in .h file.

when the new vid is coming. Loving this series :)

Hi thanks for your very informative and excellent videos.. please make a vedio every week... please please.

Late to the party, thanks for a really interesting video series! Just curious - any particular reason you're using function like macros instead of inline functions? gcc claims that they're as fast as macros, and if you use the gcc will inline even if optimization is not enabled

im starting to realize that going 64bit was more trouble then it was worth, i have no idea how im going to adapt this.

[ninnone]

Which books you follow to build os and also what programming language you should use to build os

Put already boiling water into your cafetiere, and thank me later

[СашаЯкунович-ис]

You finally made hell (sounds like hal) for bad code! (It’s a joke, you’re code so insane)

[MrDarchangelomni]

Dude did you just pour that coffee into a cup of warm milk? FUQN gross!!! The best coffee is 1.5oz coffee beans to 6 oz of water, you fill the pot make the coffee, then let it simmer until half is evaporated put in two teaspoons of sugar per 12 oz drink hot enough to cause 3rd degree burns. On cold mornings one table spoon of butter should be added.

this guy seriously put milk in the microwave... that's enough to get me to click off this tutorial
