WhatsApp is bad. WhatsApp is evil, and they do not deserve a spot in anybody’s lives. They hate their users. Note that this article will contain swear words. If you can’t handle them, look away :) TL;DR WhatsApp is evil. Meta is evil. They steal your data, they have control over you. This is just a case study; for a change, use Signal. Backstory. Yesterday morning (13th May, around 9am GMT+8) I tried to create a new community on WhatsApp, on my desktop, for an up-and-coming mathematical society at my school. ...

Finally?? Yes, this is a little bit delayed, but 3 days before the final computer science paper 1, I’m releasing this guide to help you all study. What is this? This is essentially a bank of notes for IGCSE computer science, the theory part. I will chop up my CSRG G2 semester 1 guide, which has extensive coverage of logic gates and programming, and release it independently, later. These notes are very, very detailed, so it is also a guide to some extent. ...

ezntek, you broke a promise? Yes! i said that would finish a full syllabus revision guide for all the chapters and for all the content covered, but I was not motivated to finish it all, below is a link to an incomplete coverless version with a bunch of inconsistencies, mid explanations and typos, but it surely is better than nothing. Find it here

What? IGCSEs. Cambridge-assessed final examinations. As of writing this article, it is the 5th of May, the night before my IGCSE Coordinated Science (0654) paper 41. They are quite stressful, as you can tell by the title, but it really isn’t all that much. IGCSEs are simple! All you need to do is memorize the markschemes, do past papers and you’re good. Even if you aren’t comfortable with 5 entire topics, you can watch a few YouTube videos and cram all of it the night before! Such an easy life, no? ...

DOWNLOAD! here Long time no see! Sorry for not posting so much. My workloads been very very heavy; working on projects like this one. IGCSE CS students, look out for the comprehensive whole-syllabus comp sci revision guide soon! I will release it before mocks. What is this workbook? I wrote it because my comp sci teacher let me volunteer to teach. I happily took the offer due to everybody’s cluelessness (they still cannot assign variables). So far I taught 2d arrays in front of the class, and technically this is an assignment only I was set; to make a worksheet on iteration and arrays. It is now a workbook as people need explanations. ...

Introduction yes I really should clean it. shhh! This is the story of how I librebooted my ThinkPad T480, less than 24 hours after support was added to lbmk’s tree. Note that this is not meant to be a comprehensive tutorial! Please always read the official documentation if you want to carry out this process for yourself, the steps for you and I will not necessarily be the same (as I had to build the ROM from source). ...

DOWNLOAD The OFS IGCSE Computer Science G1 Guide to Programming and Logic Gates, Revision Three What is this? I have already released this guide for the G2 students, and since your examination has so much overlap with mine, I have abridged my guide to make it so that you can use some content for your exam as well. This guide covers: The programming stuff The logic gate stuff This guide doesn’t cover: ...

DOWNLOAD The OFS IGCSE Computer Science G2 Exam Revision Reference Guide, Revision Four After much anticipation… It is finally ready, yes, the new CSRG! The TRUE Sequel to the previous one (you can find it here), where I wrote a ~40 page reference to all the topics that would be covered in the upcoming exam. However, that only did so much; this semester we are being tested on a crap ton of stuff: ...

Important Information! If you actually take IGCSE comp sci, ignore everything I say, because the examiners love seeing overcommented code for whatever reason, and they will even give you subjective marks based on if they think there are enough comments or not. To them, “well commented code” is of higher quality, despite if 80% of the code is just paragraphs and paragraphs talking about the meaning of life. Yes, I do have beef with these people. Write better code, comments are not an excuse to write bad code! ...

LibreOffice does not know my full name. What a shame! DOWNLOAD Revision Six Revision two fixed minor syntax highlighting errors, and added details to the Python half of the functions section for consistency. Revision three added a License, the CC-BY-SA-ND 4.0 International License. all previous versions are also licensed under the same license, if you have it. Revision four fixed inconsistencies in the notes, and fixed minor syntax highlighting errors. ...
