Welcome to IT Company Discussion's Private Community

Hi guys as a 26 year female working in an IT service based company, we hardly get 4 lakh per annum so what is the average salary i should earn to maintain a family and if possible please suggest about EMIs and savings we should think about.

PS: I am not talking about high maintenance, just asking the minimum amount for surviving in metros.

Need some maths below

Systems Engineer

TLDR:
I was reading up on the Navier Stokes equations today and it is so elegant that it might be my favourite math equation. 

Equation 1: ∇u = 0 (conservation of mass) states that the divergence of the velocity vector u is zero, meaning there is no net change in fluid mass.

Equation 2: ρ Du/Dt = -∇p + μ∇^2 u + ρF (conservation of momentum) expresses Newton's second law for fluid flow. It balances the acceleration of fluid particles (LHS) with internal forces (pressure and viscosity) and external forces (gravity or other external influences) on the RHS. 

This equation is foundational for modelling various fluid dynamics scenarios, from celestial bodies like stars and galaxies to F1 cars.

Long Version:
Here's how it works:

Equation 1:

∇u = 0 (conservation of mass)

So, u is velocity that can be represented as (u,v,w) vector, where u,v,w are x,y,z components of the vector.

∇u tells us that we need to do a partial derivative on u.

So,
∇u = ∂u/∂x + ∂v/∂y + ∂w/∂z = 0

or, the partial derivative of every component wrt corresponding direction is 0.


Equation 2:

ρ Du/Dt = -∇p + μ∇^2 u + ρ F (conservation of momentum)

LHS:
Since, u is velocity, then Du/Dt is acceleration and ρ is density. Newton's second law, F = m x a, applies here. Wherein, Du/Dt is acceleration of fluid particles and m is the density of the fluid.

RHS:
-∇p + μ∇^2 are the internal forces of particles hitting into each other while  F represents the external force.

F in most cases is gravity, so one can replace it with g. However, if you put in electromagnetism then, you can combine Navier-Stokes with Maxwell's equations. 

This has over time led to the development of magnetohydrodynamics, ie how stars and galaxies form. You can model the growth of our sun with this.

∇p is our pressure gradient and represents the change in pressure. Essentially, fluids move from high pressure to low pressure.

μ∇^2 represents viscous forces yielding from viscosity.

Imagine this can model aerodynamics of F1 cars.

Welcome to Office Gossip's Private Community

Let me spill the tea on what's buzzing over at Grapevine in last 24 hours. You're in for a treat with these top posts, so let's dive in ASAP:

1. ServiceNow Interview Disaster - https://share.gvine.app/yPfdLxoKeMojQ6tF6
Honey, let me spill the tea. This candidate's experience with a ServiceNow interview is messier than my auntie's spice drawer. A fresher interviewing a senior? That's like a toddler teaching a chef how to cook biryani. ServiceNow, sweetie, it's time to get your act together before you become the joke of the IT industry.

2. Poker Math for the Geeks - https://share.gvine.app/puCYn1PLfHPspDKh9
Oh, lordy, poker and math combined? This is giving very much "I peaked in high school math club" vibes. I mean, if you enjoy calculating more than actually playing the game, maybe it's time to reconsider your hobbies. But who am I to judge? Maybe that's your idea of a wild Friday night.

3. A Call for Startup Ideas - https://share.gvine.app/vckFRV2ukci1RNtq7
Babe, resigning without a plan is like going to a wedding and hoping you'll catch the bouquet – optimistic but unrealistic. But I admire the hustle; shooting your shot on Grapevine for startup ideas is like Tinder for entrepreneurs. Just don't be surprised if you end up with a partner who thinks reinventing the chai is revolutionary.

4. Delhi Travel Precautions - https://share.gvine.app/MpSzohMM64wn3F1HA
This is giving very much "my mom's WhatsApp forward" energy. But in all fairness, safety in Delhi is like finding a good samosa in Bangalore – nearly impossible. While I appreciate the caution, let's not normalize sending a full dossier every time we step out. Maybe just stick to the basics, or better yet, let's make our cities safer, shall we?

5. Sugarcane Juice > Alcohol Parties - https://share.gvine.app/9mtKHW8kBqt6Mpg5A
Finally, someone said it! Why are we glorifying alcohol when we can party healthily? I'm all for replacing beer with sugarcane juice, but let's not pretend like we'll stick to this plan once "Gallan Goodiyaan" starts playing. Still, cheers to the idea – it's sweet, both literally and figuratively.

6. Rahul Gandhi's Employment Plan - https://share.gvine.app/c5JbZA9j3JFckzAG8
Oh, Rahul, always the dreamer with plans as realistic as my chances of marrying Ranveer Singh. Promising money for watching reels? That's not a job strategy; that's called being a Gen Z with too much time. How about focusing on real employment solutions, or is that too mainstream?

7. Max Salary for 20-Year IT Experience - https://share.gvine.app/7mEb8DnZB3LNYn9N6
Asking for the max salary in IT is like asking how spicy is too spicy – it's subjective, darling. But let's be real, the IT market is more unpredictable than my mood on a diet. So, aim high but maybe don't start planning your mansion just yet.

8. Arrogant IITs Not Getting Jobs - https://share.gvine.app/xBHQYM5AxDxE6JHS
Saying IIT grads are arrogant is like saying water is wet – we've all met that one guy who won't shut up about JEE ranks. But let's not generalize; not all IITians are boastful, and not all non-IITians are humble. It's about skill, not the label on your degree.

9. The Beauty of Tech Projects - https://share.gvine.app/62rBG77cHN9xF1r38
This is the tech equivalent of finding your tribe. Working with a dream team on projects you love is rarer than a peaceful family WhatsApp group. It's beautiful, it's pure, and it's about as common as understanding your privacy settings on the first try.

10. The Indian FAANG Roadmap - https://share.gvine.app/5gBHzBjHrBDGoR7v8
Oh, the classic FAANG cycle – from aspirational YouTuber to disillusioned course creator. It's like the startup version of a Bollywood movie: predictable, dramatic, and with an inevitable downfall. But hey, if you can't join 'em, teach 'em (for a small fee, of course).'

Oh, the drama on Grapevine never fails to entertain.

Whether it’s the hilariously out-of-touch interview processes, the nerdfest of math-heavy poker strategies, or ambitious claims in politics and business, Grapevine serves it up fresh and hot daily. 

It’s the perfect blend of reality check and escapism. Always insightful, often hilarious, and occasionally face-palm worthy – keep the posts coming! 

What’s next, Grapevine? We're all ears!

Saw this reel, and it makes so much sense

You have Republic day sales going all over, or end of season sales

Anything remotely associated with love, heart or red will go up price multifold by Feb first week

Oh you guys earn 2.5 cr a month, nevermind ignore it 🤐🤐

Buy Valentine's gift in January

Happy pi day to all the math nerds out there!

I would recommend watching the latest video of Matt Parker on the youtube channel Stand-up Maths where 100s of people try to beat a pi calculation world record!

Happy pi day

Not a Ctrl {C+V}

I never used the Blind app to say, "People connected to each other over a thread and planned to meet outside the app, calling it a Blind date". Not giving any shit about that app.

Why don't we start it here again? - NCR people are no less

Let's see if we can beat bumble and shaadi.com - No need to beat the shit, just date

Just enough to drop your details in this format.
(Gender: M/F) | (Age) | (Location) | (One liner bio that won't disclose your identity)

Example:
M | 29 | Gurgaon | I like this, not that



P.S: I am not taking any ownership for anything happening under this post, I am not a matchmaker. All the best!

Changed the title from Blind Date to Wine Date, cheers to Grapevine ;)
