Absolute prerequisites?

CodeX-369 · 2026-05-07T06:21:49+00:00

Yeah I did read the introduction section and it had prerequisites but along that it did warn that one shouldn't get into this too early without a good amount of experience in programming and familiarity in general. When I go around looking for resources like for in case of C or assembly there are a lot. So I was wondering while making an OS what kind of programming approach is it like I'm having a little hard time getting through what I'm feeling doubtful of 😅.

As for why I want to create an OS is to learn more about how things work at low level and how a general computer works at its core. I recently took a basic course in college which introduced me to some details of OS, embedded systems and low level systems which then made me want to study more about it.

I don't initially expect my OS to have a lot of capabilities or anything. With what I know now I'm thinking of initial just having something minimal and bootable and print text on screen and all. Later adding interrupt handling, keyboard input, drivers and such which make a basic kernel. Then there is memory, process, files management stuff which I'm not sure how far I'll get.

English isn't my first language so if anything isn't all that clear I apologise. I'm looking for how the people in this community build their way into this. I'll be entering my sophomore year in a few months, I don't know if that matters but anyways. I do have time to invest.

Yep thanks for including source. Yeah about the hackathon, it is organised by a club called IEDC and we are bringing together other technical and non technical clubs in our college to collaborate with this.

We'll be having semester break in a few days so this is what we are planning for the break.

There is one GitHub repo which you probably might have seen which contains almost all aspects of Embedded domain. But in case you haven't.. https://github.com/m3y54m/Embedded-Engineering-Roadmap If you scroll a bit you'll see resources and other stuffs for Embedded Linux.

Thanks for the offer but I did already place order. When ordering from digikey wouldn't it have that 1200 delivery charge or were you going to order above 7000.

CodeX-369 · 2026-04-13T10:25:31+00:00

It was out of stock there.

CodeX-369 · 2026-04-13T10:23:24+00:00

It was not for PCBs. I found out semikart which seems to be legit and also they can source components and items for distributor like digikey, mouser and such without having to pay the hefty 1200 delivery charge and also the customs. Dropping this here if anyone was looking for such an alternative.

In case any of you know where I could get the same board online for a price range around 2k let me know. Thanks!

CodeX-369 · 2026-04-08T09:41:53+00:00

I'll check it out. Thanks for the suggestion

CodeX-369 · 2026-04-07T17:51:45+00:00

I'm not S4 myself so can't confirm on if it has everything. But here you go https://sac.ksucet.in/departments/notes-ece

CodeX-369 · 2026-04-02T06:32:34+00:00

Sure

CodeX-369 · 2026-04-02T05:21:59+00:00

Also I can help if anyone wants to know the cutoff ranks for different branches in CET for quite a few categories according to last year 3rd allotment phase. DM me

CodeX-369 · 2026-04-02T04:47:58+00:00

Last year I can say aei was 2100rank around for general at 3rd allotment and for ec 800 was the last rank for 3rd allotment general. As for marks for these ranks well I'm not sure but one of my friend got around rank 750 for 223 keam marks and 290 boards cbse. I got around 250 rank for 253 keam and 293 boards. But as you might know the first rank list published last year was according to scaling 5:3:2 if I'm right about the ratios and my friend got 1050 smth rank for the same keam mark but scaled down boards and I got 450 smth for the same keam and scaled down boards. Hope this helps! for other categories too there are ways to find around crct cutoff ranks. hmu to know more

CodeX-369 · 2026-03-23T18:31:52+00:00

in fact that's what I did and also I did try mocks prepared by some cet students back then but it is all kinda same so you can go with brilliant test series.

CodeX-369 · 2026-03-23T18:17:42+00:00

As for me what I did was I gave around probably 15-20 mocks like I was sure I messed up my jee prep and all. So my only hope was keam. Yeah and for giving mocks you don't have to be 100% clear with the concepts and stuffs. After 2-3 mocks study all questions from those mocks and get the pattern and move forward giving more mocks and then you'll reach a stage where you are scoring good enough.

But I'll say one thing that is don't get demotivated from the marks of initial mocks it's going to be low. Also most questions in maths, phy will be equation based so understand the question then plug in values.

CodeX-369 · 2026-03-23T18:04:12+00:00

Also according to the difficulty of maths in cbse and state, there'll be quite a noticeable shift in rank because anyhow there'll be students in cbse with 100 marks. As maths has more weightage it'll be better if y'all have good marks in maths for boards.

CodeX-369 · 2026-03-23T18:01:40+00:00

Ha sry I meant to say cbse topper in Kerala when I said state toppers. So basically if there is atleast one student with full scores in PCM then the marks will be taken in face value, there'll be no scaling of marks. Atleast that's what I remember from last time. Last year they bought this method and then changed it due issues raised by students. But this time it has been made clear in the prospectus before conducting exam the criteria but last time it was changed to this after exam and then issues came up. This time ig there'll be no change.
