Started my morning with GATE Aptitude

Today's numerical aptitude felt more like Maths than Aptitude

Key learnings:
• Probability of most likely success → Binomial Distribution
• Exponential relationships & inverse trends
• Fixed a silly average calculation mistake: dividing by questions instead of students

Small mistakes, big lessons.

@rubenssoto_ai @X Obv dude let's connect

[Sayantan @SayantanDev7]

Hey @X algorithm
I'm looking to #connect with people interested in: >SaaS
>Frontend
>Backend
>Fullstack
>Mernstack
>AI/ML
>Data Science
>Technical Writing
>Building in public

If that's youu, Let's grow together 🤝

@archnarambles lets connect sis 🙃

@thisis_chandru I am using HTTP-only to protect the JWT from JavaScript of the browser, secure only in production for HTTPS, and sameSite=strict to help prevent CSRF attacks 🙃

Built the auth gateway for Moody Player today.

Signup → Login → Logout — all connected to my Express backend via Axios.

JWT in cookies. bcrypt hashing. Protected routes.

3 weeks ago I didn't know what a middleware was.

btw hows the UI

give some feedback guys 😃

@pran_vi24 thank u bro

[Sayantan @SayantanDev7]

@Sarthak_Hire yeah keep building
and keep following mee for more backend learning
feel to free ask any query or doubt

@shakhzod1001 My pick: event loop, closures, CSS specificity, React reconciliation, and controlled vs uncontrolled components.

[Sayantan @SayantanDev7]

@shakhzod1001 balancing both 😂

[Sayantan @SayantanDev7]

@Rishikesh04code Always bro. No stopping. 😀

[Sayantan @SayantanDev7]

@ShankarCodes @X Done 👍

[Sayantan @SayantanDev7]

@raf_piek @X Nice to meet u too

[Sayantan @SayantanDev7]

@Shubham__218 @X Done bro from my side 😀

[Sayantan @SayantanDev7]

@wensitylabs @X Done bro

[Sayantan @SayantanDev7]

@draft_ofkritika which college?

[Sayantan @SayantanDev7]

10+ hours. One topic. Finally done.

Wrapped up Boolean Algebra — one of the highest-weightage areas of Digital Logic for GATE.

Went deep into the properties of AND, OR, NOT, NAND, NOR, XOR & XNOR and how they can be used to simplify Boolean expressions.

Took 10+ hours, but understanding the why behind each property made it worth it.

#GATECS #DigitalLogic #ComputerScience

[Sayantan @SayantanDev7]

Deep-dived into NOR gates for GATE.

Covered:
• NOR properties & implementations
• Implementing expressions using NOR
• Why understanding NAND makes NOR easier
• Finding the minimum number of NOR gates needed for an expression

Digital Logic is becoming less scary and more interesting.
