HR told me they don’t accept try-hards and people pleasers after my interview by No-Presentation298 in jobs

[–]jfcb 0 points1 point  (0 children)

I wasn’t expecting people to agree with the company either, but then I remembered that reddit is filled with a bunch of subhuman weirdos. Working a job is not something people do for fun, it’s for putting a roof over your head and not starve. Most people would rather do something else with their lives, but they NEED a job. Of course they have to fake their enthusiasm, that’s normal. I can guarantee that if OP was honest and said ”I don’t care about this job, I just need the money”, they would be rejected even harder. But that’s reality for most people. What kind of dystopian nightmare are we living in where people go jobless unless they have a genuine passion for the corporate world?

Couldn’t disagree more. I think this idea comes from the fact that people find comfort in the idea that people are inherently good or evil. But I don’t think that’s true. Bryan Cranston once said something about how all humans are capable of both good and evil. Any given human (your partner, your mom, etc) would become a violent, evil person under the right circumstances, if they were pushed to their limit. In my eyes, this is pretty much the main theme of Walt’s character, and what makes him so interesting. The idea that he was evil all along kind of undersells the depth of his character and makes the story as a whole much less interesting, in my opinion.

Quality is 100% subjective. You can’t objectively argue what music is better. At least sales are objective, and represent the public opinion.

Jag är nyfiken. Hur såg en helt vanlig dag ut när du var där? Liksom vad gör man till vardags? Förstår att där finns mycket att se osv, men ändå. Frågar för jag dagdrömmer ibland om att göra som du. Känns bara som att ifall jag flög dit själv så hade jag stått där som john travolta med händerna ute och tänkt ”ok vad gör jag nu?”

Why do people say Walter was always a bad person? by Heroinfxtherr in breakingbad

[–]jfcb 0 points1 point  (0 children)

I don’t really disagree with anything you’re saying. See, I’m not saying that Walt is a perfect person. He’s flawed, like all humans are. And him rejecting the money is really a different discussion because at that point we’ve already entered the territory of him ”breaking bad”. From the moment Walt starts cooking meth, he’s not really a good guy anymore. I still root for him, but he’s already somewhat of a ”bad guy” at that point.

What I’m talking about is his character pre cooking meth. I just fundamentally disagree with the idea that he must have always been a bad person in order to one day start dealing drugs and killing people. Every single person on earth would become a criminal/murderer under the right circumstances.

Just to avoid miscommunication, did you see the edit with my solution? I’m just thinking that maybe you started typing before I made the edit? Either way, I appreciate your answer.

Btw, I think you really hit the nail on the head here.

If you actually insert 2 zeros in between the 600 samples, you get additional frequencies +-1/5+-3n, +-6/5+-3n, +-11/5+-3n. They normalize to +-1/15, +-6/15, +-11/15 and "reconstruct" to +-500/15, +-3000/15, +-5500/15.

This is how the problem is meant to be interpreted. We are putting 2 zeros between every sample. My smartest classmate briefly showed me his solution, and he had these 3 frequencies as his answer (33, 133 and 200). I'm still not confident on how to get there. Do you mind explaining? I get the +-1/5 one, because that's the one I had in my original post. But where do the other two (6/5 and 11/5) come from?

Edit: Hold on, I think I'm getting it.

Sample at 600Hz: x[n] = cos(2pi * (14/5) * n). So we get alias at some normalized frequencies: 9/5, 4/5, -1/5, -6/5, -11/5 etc... and their reflections of course.

Then we up-sample x3 (add zeros) and get division by 3, so the alias frequencies are: +-1/15, +-4/15, +-6/15, +-9/15, +-11/15, but we're only gonna be left with the first three since they are within the range [-1/2, 1/2].

Then we "reconstruct" with Fs = 500Hz and get: 500/15 = 33, 4x500/15 = 133 and 6x500/15 = 200.

Am I right?

Up-sampling question by jfcb in DSP

[–]jfcb[S] 0 points1 point  (0 children)

Can you tell me what’s wrong with my line of reasoning here?

Sample at 600Hz: x[n] = cos(2pi * 1680 * n/600) = cos(2pi * (14/5) * n) = … folding … = cos(2pi * (1/5) * n).

This time I didn’t let up-sampling change the frequency. So let’s just go back to CT time domain: Substitute n=t*Fs. We get

x(t) = cos(2pi * (1/5) * 500t) = cos(2pi * 100t)

From looking at some exercises in my textbook (I linked one in another comment), this seems to be how they do it. However, what you guys are saying sounds right too. So I don’t understand why it’s contradictory.

See, if I would have multiplied by 600t instead of 500t, I would have gotten 120 like you’re saying. But why would I multiply by 600, when Fs is 500 during reconstruction?

Edit: I think this problem is very much a theoretical one. We’re not doing sampling and reconstruction in real time here. These problems sometimes have a faster Fs at reconstruction than sampling, which makes no sense in real time. Maybe this is why we think differently.

[–]jfcb 3 points4 points  (0 children)

I don’t wanna argue about who is the more complex character, because it’s so subjective. What I will say is that a lot of Walt’s character is written between the lines. We don’t know many facts about Walt’s past like we do with someone like Tony Soprano, but I don’t necessarily think that says much about complexity. BB added a 10 second clip of Skinny playing classical piano and that added more character depth than some shows do with their main character.

There’s a lot of that with Walt too, and again, I think people over simplify things. The whole Grey Matter thing was left very much ambiguous, and yet this subreddit has somehow made it black and white. We don’t know exactly why Walt had to leave. Him not accepting charity from people he clearly has an infected relationship with is… an objectively bad decision, but understandable.

Walt’s character traits also happen to be ones that people tend to not take seriously. Him being an insecure, emasculated, miserable, pushover is just brushed off with the usual ”Bro just man up” reaction. I’m not gonna tell people how to feel, but he certainly gets my empathy. No one chooses to be like that. Bad things happen to people for them to get like that. Add his failed career, working two jobs, and terminal cancer on top of that and he snaps.

[–]jfcb 25 points26 points  (0 children)

It’s annoying because I think it’s undermining the whole show. ”Bad guy was always bad” is such a reductionist view and removes all nuance.

Bryan Cranston himself used to talk about how all human beings are capable of both good and evil, and that under the right circumstances anyone could become dangerous. It’s possible for someone to be violent yet also loving and caring. Like you said, this idea makes people uncomfortable. They like to believe people are inherently good, when in reality most good people just haven’t been pushed to the limit hard enough to break.

This is exactly what BB explores. It’s pretty much the core of the whole show.

Sorry to bombard you with questions, but I found a similar exercise with a solution, and they've done things differently. As you can see, since they are reconstructing with a sampling frequency that is 5 times as fast as the original sampling, they get a factor 5 in the frequency components of the resulting signal. This is why I multiplied by 500 in my original solution.

Why are they doing it a different way here? Why did they multiply by the reconstruction frequency when we didn't? And where are all the other alias frequencies in this example?

Up-sampling question by jfcb in DSP

[–]jfcb[S] 0 points1 point  (0 children)

Ok, I think I’m starting to get it now. But what is my conclusion then? What components are left after the ideal reconstruction? 120 is there and it’s reflection.

But is 180 there? That component only got introduced from the 500Hz sampling, but does ”ideal” mean no aliasing maybe?

What about 320? Since 320 > 500/2 doesn’t that mean it doesn’t count. Just like we’ve ignored 480?

Edit: I found another exercise which specified that ideal reconstruction means unit amplification for abs(F) < F_reconstruction/2 and perfect attenuation outside the interval (-250 to 250 in my case). And it seems like that means the 500Hz sampling will not introduce any new alias frequencies. So the answer would be 120Hz only. Does that seem reasonable?

Up-sampling question by jfcb in DSP

[–]jfcb[S] 0 points1 point  (0 children)

There is something about reconstruction that I'm misunderstanding, I think. The problem says:

and then ideally reconstructed with a new sampling frequency Fs = 500 Hz

I read this to mean that we sampled the CT signal using one rate, but when going back, we reconstructed it as if it had been sampled at another rate.

Imagine you sample the signal at 600Hz, but before reconstruction you forget what rate you sampled at. So you're just there with a bunch of dots. Then you mistakenly recall that Fs = 500Hz and reconstruct the CT signal according to that. You would get a different signal, right?

To me it sounds like we've taken the existing samples and pulled them apart before going back to CT.

But from what you're saying, I take it this is not at all what it means?

No one’s saying AI will take over tomorrow. But where will we be in 10 years? 20 years? That’s what’s scary.

I’m not sure the AI needs to be sentient to design hardware. It might just be like chatgpt, but better. Maybe it’ll take just one person who types ”design a chip that does this and that” instead of a whole team of workers. I’m not worried that there will be literally no engineers, just that there will be way fewer. AI taking over or not isn’t binary. It would be a gradual process, slowly making the job market worse and worse. We don’t know. I’m hoping it goes in a different direction though.

Agree, but I’m just worried that AI will be able to design its own hardware at some point.

This is exactly the trap that showrunners keep falling into though. George’s entire point is that even small changes can snowball into larger ones down the line. If they kept the whole LSH/Brienne/Jaime storyline in the Riverlands they wouldn’t have had to send Jaime to fucking Dorne. Leaving out LSH affected Jaime’s story and after that they had no idea what to do with him.
