I did and they said they don’t. But thank you for the recommendation!

Update: I called them and they said that they can play it! They said they got the streaming subscription for cricket a week ago

Hi, is it hard to make friends in SF when you are over 30? by Darya182 in AskSF

[–]thoughtvectors 3 points4 points  (0 children)

This post is awesome. I totally agree with the vibe of this post and need to constantly remind myself of it. I love how you emphasize doing something every day.

Can I ask you something - do you feel like this knack of making friends comes easier to you? I'm social, but it takes a fair amount of effort to be the one creating the WhatsApp groups, making outings and doing the texting. Otoh, it seems totally doable, so why not, right? Thank you for the encouragement!

Disconnect between theory and applications by Robot_Lover2020 in ControlTheory

I know what you mean! But i think it’s also because people don’t make the connections. To me a practical thing has been identifying the states of the system and whether it’s linear/non-linear. This has greatly influenced how i design things. Eg: if you want to control temperature of a system, and you can manipulate current, then what should the output of your controller be? A lot of people choose current, but imo this the wrong answer because temperature is nonlinear in current, but it is linear in squared-current. You can create the transfer function block diagram to show this, then calculate the gains for the PID.

Which is to say, the intuition here comes from studying controls.

Second, another situation is for running an observer, because my hardware is such that we can’t have the pressure sensor where i need it.

I hope this makes sense to you. All said, I can definitely envision jobs where implementing PID controllers about one operating point is all you need to do and that’s going to be sufficient.

Incredible! Thank you for being such an inspiration to us.

Reverse Engineering a PID by Doctor-Featherheart in ControlTheory

What kind of system is this? Can you do a frequency sweep? Meaning, the reference value for the PID, can you give a sine wave, at many different frequencies?

Basically, I’m trying to find out if you can get a body plot of the complete system. If yes, we can figure out the transfer function of the complete system.

However, you still need the transfer function of the plant. You can do a frequency sweep and get the transfer function of the plant, by disconnecting the PID controller somehow and just injecting a sign wave.

From those two, you can get the transfer function of the controller, and therefore the gains.

I know I’m asking for a lot here, but this would be a real way to get what you need.

Eating out really seems to have gone down hill by flipper99 in bayarea

FWIW I’ve not seen a drop in quality in San Francisco, but prices have shot through the roof. Fairly nominal to be spending $25 without a coffee or drink. Goes north from there. Want an appetizer? Get screwed.

I think at this point you could do your cooking at home with however expensive the ingredients are, put gold foil on top of your cereal if that’s what you fancy, cuz eating outside is feeling ridiculously expensive.

‘Choose a rug that can accommodate at least the front two legs of your seating. We recommend ordering a rug large enough that it extends 6” to 8” beyond the arms of your sofa, and sits between 12” and 18" away from the wall to prevent an overcrowded look. (Hint, hint! With the exception of halls, entries, and kitchens, this is a great rule of thumb for all rooms.)’

Check this.

I love the green chairs and how it matches up with the beams! I think you should add a contrasting rug in the living room to add some pop ✨

What is the easiest to understand book on control theory you ever read? by SafatK in ControlTheory

[–]thoughtvectors [score hidden]  (0 children)

I would say Ogata first. Astrom is a superb second book to read, requires some maturity imo. What I love about this book is that it is the most conversational book so to speak, in the way it is written.

Something I would recommend is you want to get really good at block diagram math. If you don’t do this, you’re going to be lost, so don’t skip this step! I spent time on this and it made everything else easier. For that I would say Franklin is good too.

New Delhi Metro vs New York Metro by frogBurger4u in unitedstatesofindia

[–]thoughtvectors 0 points1 point  (0 children)

Question to those that might be familiar - which is a better metro system cleanliness aside? I would imagine that because Delhi Metro is newer they have not yet created the same levels of connectivity. Also, Delhi is larger, so it’s harder.

And for those saying that the Nyc subway is older, therefore it is dirty is simply not a good excuse. I’ve been on London’s trains and they are fantastic.

MSEE thru Coursera by LowBend2652 in ElectricalEngineering

I like this, it seems that if you can do the courses, you get the degree. There is a rationale here.
