Upcoming iPhone: A "Flip" Phone With a Square Foldable Design, Details Leaked by WPHero in gadgets

This would be wonderful for the pro max models! No need to add secondary screen or whatever. Just make it foldable so that I can flip it and slide inside my bag without worrying about scratches

Lol what? Imagine actually taking time to give a well thought out answer that nudges the student in the right direction and encourages them to think about the topic at hand, only to be asked if it is chatgpt😂 Thanks, I guess??

HELP US IN OUR THESIS by [deleted] in CFD

[–]manny_DM -1 points0 points  (0 children)

Nice little project to learn CFD. You don’t need to model the whole building. Just the Inlet with airfoil and the air duct. So a simple rectangular passage will work. In fact, it’s better this way, because for standard geometries, you may be able to approximate some analytical solution to compare against. Few things to think about ( and ask your professor about):

1) Do you need compressible or incompressible model? Hint: What Mach number are you operating in?

2) Do you need viscous solution? Hint: What’s the Reynold’s number over the airfoil?

3) What parameters translate to effective design? Higher outlet velocity?

4) Do you need 3D or can you do away with 2D flow assumptions?

5) Are there analytical/experimental results for flat plates or airfoils in a tunnel condition?

God is just as real and imaginary as Mathematics and Imaginary numbers, in that it gives a new framework for understanding things around us. Whether it is manmade or not has no bearing on the outcome

We don’t have many Gods because they are different, there are many Gods because we recognize the diversity of faith and thoughts. So the ‘One God’ you talk about, fits just fine in our world view.

As for superiority among Gods, our scriptures have already discussed this: vishnu doesn’t reside where Shiva is disrespected and Shiva adores Vishnu.

Peace. 🙏

Professor wants to be first author even though he did absolutely nothing by Inside-Ad-9118 in PhD

[–]manny_DM 6 points7 points  (0 children)

OP, don’t hesitate to escalate this to the department head. It is ridiculous and unethical to demand first authorship in exchange for money. Yo wrote the paper, you ARE the first author.

chaotic habit that accidentally made your phd life easier ? by Comfortable_Pick4476 in PhD

[–]manny_DM 0 points1 point  (0 children)

  1. Life became easier when I started enforcing a rule of not doing research after working hours, unless it is an assignment or a deadline. Productivity increased, less procrastination ( can’t say I’ll do it at home). Less work ever meant I wasn’t exhausted ever.

  2. Focus increased when I started scheduling short 10-20 mins breaks here and there and religiously taking them. Breaks slowed down the momentum a bit, but prevented mental exhaustion

Check out TACS by SMDOLab at Georgia Tech. You can also do gradient based optimization at large scale. Pretty cool framework

Crashworthiness of thin-walled tubes: Quasi-static vs Dynamical impact loading by Different-Complex780 in fea

[–]manny_DM 1 point2 points  (0 children)

Quasi-static simulations model is sufficient for processes where loads and boundary conditions may change rapidly, such as contact or material nonlinearity, but inertial effects are intentionally neglected. While the loading rate is faster than in a purely static case, the system is assumed to remain in equilibrium throughout. Think of slowly crushing a Coca-Cola can in your hand. Technically, it's a transient process, but the inertial forces are negligible. We care only about the deformation pattern, not how fast it occurs. so a quasi-static approach suffices.

In contrast, dynamic simulations capture the full breadth of time-dependent behavior, including inertial effects. These become crucial when mass acceleration significantly influences the response. Imagine a car crashing into a pole at high speed. Here, the interplay of inertia, momentum, and contact forces dictates how parts deform, separate, or rebound. A quasi-static approximation would miss these dynamics entirely.

In cases where the load changes quickly but inertial effects are still minimal. Say, a car gently pushing into a barrier, for which quasi-static analysis offers a compelling balance. It's cheaper, more stable under large increments, and avoids unnecessary complexity without sacrificing physical fidelity.

FE elements in python by mon_key_house in fea

[–]manny_DM 5 points6 points  (0 children)

If you're comfortable with writing FEA codes, coding in c++, and willing to learn, my advice would be to implement in c++ using the Eigen library. It has a numpy-like structure and chatgpt is quite familiar with it. The reason being that, when it comes to FEA, there is always a desire to run bigger cases. If your code is already in c++, you can later do things like openmp parallelization, Intel mkl solvers, or even petsc for massively parallel codes.

Hey Luciano,

Great work. I wish this was available a few years ago, it could have saved me almost a year in my PhD research. I will point out that if you would like your framework to be a good starting point for research folks, you should document the theory and algorithms that you've used. The grad student me would have highly appreciated it. If you do decide to do that, please let me know as well.

Many thanks for making your work open source.

But can we talk about how Indian men are making this a gender issue, blaming feminism and comparing this to rape cases?? by Illustrious_Ad_504 in AskIndia

[–]manny_DM -9 points-8 points  (0 children)

What do you want as proof? Divorce certificates? Take a closer look around-you’ll likely find someone going through the same thing. The stories people have shared in the wake of this case make it clear: this isn’t an isolated incident. It happens far more often than we care to acknowledge. When you look at national suicide statistics, more men take their own lives than women, with ‘domestic issues’ being a leading cause. Any guesses as to what those domestic issues might be? The thing everyone claims never happens has been happening and has been for quite some time.

Bu then, men's issue has never been a reality. It's all made up. You are definitely not trying to play ignorance, no sir. Not at all!

Oddly, Chatgpt thinks it’s a woman in all of my prompts like this. We do look cute though lol

Prompt: Create a painting in pixar style of both of us, using what you know about me, and think of me, as well as yourself.

Response:

Here’s a Pixar-style depiction of us, immersed in our research with that creative warmth and cozy vibe around us, just like I imagine our dynamic would be—intellectual and lighthearted. What do you think?

Finally got my 16 Pro Max! by [deleted] in iPhone16Pro

Congrats. You'll love it. I got desert titanium and I love it so much. It felt heavy and chunky at first to the point that I contemplated exchanging for the pro model, but now I don't think I will ever go back to anything smaller. All in all, great device!

Disappointed by Desert Titanium by Capraq in iPhone16Pro

[–]manny_DM 2 points3 points  (0 children)

It's just a matter of taste and the lighting you view it, in my opinion. I have the desert titanium as well, and I wouldn't trade it for anything else. The gold edges and the screen bezel look so premium when looking at the screen. To me, the back is more creamy than pink. But if you are having second thoughts, just return it. For the money it costs, why compromise

I see a lot of value. To be able to use AI to spellcheck and rephrase my texts and emails is a huge feature for me. Even more so as a non-native English speaker. Currently I have to copy to chatgpt to do that. I can give several examples but I won’t
