claude mythos explained for people who don't want to read a whole article
→ new anthropic ai model (april 2026) → found bugs that are OLDER than most gen z → created 181 firefox exploits (previous model: 2) → 1 million token context window (read entire codebases basically) → not available to the public. invite only. 50 companies max. → costs $125/million output tokens which is a lot
the companies that got access: aws, apple, google, microsoft, nvidia, cisco, crowdstrike, palo alto… the usual trillion-dollar crew
what does this mean for you? probably nothing immediately. claude opus 4.6 is still publicly available and also very good.
but it does mean we're at a point where ai can autonomously hunt through decades of code and find vulnerabilities humans missed for generations
that's either very exciting or very concerning depending on your general disposition toward the future

Board Exam के आखिरी 10 दिन — यह गलती मत करना
परीक्षा में 10 दिन बाकी हैं और ज़्यादातर students एक ही गलती करते हैं — नया topic पढ़ते रहते हैं।
यह काम नहीं करता। कभी नहीं करता।
तो करें क्या?
इन 10 दिनों को 3 phases में बाँटें:
Phase 1 (Day 10-7): पूरे syllabus का एक quick scan। Priority list बनाएं — heavy topics पहले। Previous year papers देखें — pattern समझें।
Phase 2 (Day 6-4): अब सिर्फ पढ़ना नहीं, लिखना भी। Book बंद करके recall करें। Mock test दें — time limit के साथ।
Phase 3 (Day 3-1): सिर्फ अपने notes। नया कुछ नहीं। बस जो बनाया है उसे देखें। रात 10 बजे तक सो जाएं।
एक honest बात: 10 दिन miracle नहीं करते। लेकिन सही strategy से passing marks से ऊपर जाना बिल्कुल possible है।

okay so I made a CGPA calculator and it's actually really useful 🧮
three modes because one size doesn't fit all:
mode 1 — you have grades (A1, B2 etc.) just select from dropdown → done ✨
mode 2 — you only have marks (like 88, 75, 92) enter the numbers → calculator assigns grades automatically you don't have to do anything extra 🙌
mode 3 — you already know your CGPA just enter it → get percentage instantly (formula: CGPA × 9.5, not × 10 please 😭)
also shows you: → subject-wise breakdown → performance label (outstanding/excellent/very good…) → copy button so you can share with parents lol → warning if you failed any subject ⚠️
free to use, works on phone too: 🔗 https://www.hinditechbook.com/calculators/free-cgpa-calculator-in-hindi/
CGPA kaise nikale? — सबसे simple explanation
1/ Formula एक line में: CGPA = सभी subjects के grade points जोड़ो ÷ subjects की संख्या बस इतना। 🎯
2/ Grade Points याद करो: A1=10 | A2=9 | B1=8 | B2=7 C1=6 | C2=5 | D=4 (CBSE 9-point grading system)
3/ Real Example — Class 10: A2+B1+A1+A2+B1 = 9+8+10+9+8 = 44 CGPA = 44÷5 = 8.8 ✅ Percentage = 8.8×9.5 = 83.6%
4/ Marks से CGPA निकालना है? 88 marks → A2 → GP: 9 75 marks → B1 → GP: 8 92 marks → A1 → GP: 10 65 marks → B2 → GP: 7 83 marks → A2 → GP: 9 CGPA = 43÷5 = 8.6 ✅
5/ Popular Calculations: 76 ka CGPA → 8.0 7.8 CGPA → 74.1% 4.0 CGPA → 38% (minimum pass) 10 CGPA → 95%
6/ College Students के लिए: SGPA se CGPA kaise nikale? सभी SGPAs जोड़ो ÷ semesters की संख्या (equal credits होने पर)
7/ Common Mistake ❌ CGPA × 10 = Percentage — WRONG CGPA × 9.5 = Indicative Percentage — CORRECT ✅
8/ Complete guide — Class 10, 12th, BSc सभी के लिए step-by-step: 🔗 https://www.hinditechbook.com/cgpa-kaise-nikale-cgpa-calculation-guide/
CGPA kya hota hai? — हर student को पता होनी चाहिए यह बात 👇
1/ CGPA = Cumulative Grade Point Average CBSE का 9-point grading system जिसमें maximum grade point 10 होता है।
2/ Grade Points याद करो: A1=10 | A2=9 | B1=8 | B2=7 C1=6 | C2=5 | D=4 E1, E2 = Fail ❌
3/ CGPA निकालने का formula: सभी 5 subjects के grade points जोड़ो → 5 से divide करो Example: 9+8+10+9+8 = 44 ÷ 5 = 8.8 CGPA ✅
4/ Percentage चाहिए? CGPA × 9.5 = Indicative Percentage 8.8 × 9.5 = 83.6% (यह approximate है — exact नहीं)
5/ SGPA vs CGPA: SGPA = एक semester की performance CGPA = सभी semesters की combined performance
6/ Common Myth ❌ "10 CGPA = 100%" Reality ✅ 10 × 9.5 = 95% — 100% नहीं!

Pomodoro Technique for Students – Study With Better Focus
Many students struggle to stay focused while studying for long hours. The Pomodoro Technique is a simple time-management method that helps improve concentration by breaking study time into short intervals.
The basic idea is simple: • Study for 25 minutes with full focus
Take a 5-minute break
Repeat the cycle 3–4 times, then take a longer break
This method helps reduce mental fatigue and makes studying more productive. Many students use it to prepare for exams, complete assignments, and manage daily study sessions.
If you want to understand how this technique works step-by-step, you can read the full guide here:
