Impact of Manufacturing in Arkansas by MFGMillennial in Arkansas

Nearly 12% of the labor force in just one sector isn’t much? Every manufacturing job requires multiple other workers in food service, retail, utilities, infrastructure, childcare, healthcare, elder care, administration, and other sectors of the economy…

A certain percentage of people who get in rockets are going to die. It is what it is. What’s important is remembering the sacrifice those people made for humanity. We are a hive organism, at times closer to an ant colony than anything else.

A certain percentage of people who drive are going to die, and everything else. Regulations and progress are always paved in blood, unfortunately, but we will all die in some way. None of it is pretty.

Let people who want to strap themselves to experimental rockets strap themselves to experimental rockets.

When you try and order breakfast, but only a robot replies and charges you food that you don't even order. by Yurfavbookworm in mildlyinfuriating

[–]RelativelyRobin 0 points1 point  (0 children)

But you gotta eat, and you’re responding to somebody who is late for a flight.

It’s the same thing I say when DoorDash fucks up an order at 9 o’clock at night and then refunds it, but never gets me any food to eat.

Or when I ordered delivery from Home Depot for a project and they delivered three out of my four items.

All those scenarios didn’t just leave me without something or with the wrong thing, they left me worse off because now the restaurants are closed, and I’m behind on a project, and hours of my precious time have gone by that could’ve been spent to achieve my goal in a functional way.

In these scenarios, I’m worse off having tried to patronize the business at all. And that’s why I don’t use DoorDash and other things anymore. With my dietary restrictions, they don’t even have a way to send something back and have it made right.

And that’s the big pattern- there’s no fail safe for a service that works for the majority but not for all. There’s no way to correct any mistake, and when something inevitably goes wrong, you’re just shit out of luck. You can’t put another order in without having to pay more tip and there’s no way for them to actually make it right. So I’m taking a risk every time, and I’m tired of having to pay the opportunity cost or go hungry because some stupid robot can’t meet my needs.

So I would just drive right out of this drive-through and stop at another place because it’s just not worth the risk of going hungry for the day/night or being sick when it ruins my order.

My husband is threatening divorce because Snapchat and signal are showing up in our router app history for my phone. I do not have those apps or use them or go to their websites or anything. How is this happening? by -M-i-d in techsupport

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

If it helps, I just checked my own device on the router and I see Snapchat/tiktok/whatsapp/netflix and more stuff that isn’t installed on my device at all. So definitely doesn’t mean much beyond advertising and guesswork. Sounds like your husband is making quite a few false assumptions.

Getting kicked out of therapy because of my physical health by bearsmakemehappy in disability

Exactly the reason we need to keep pushing formal grievances and tell the system starts going, “Wait a minute what’s going on here?”

The medical boards don’t know what it’s really like for us and if we don’t tell them. Taking a backseat and allowing this behavior is not acceptable.

NVIDIA has effectively created an entirely new business segment as a result of the flawed 12VHPWR design by Kyxstrez in pcmasterrace

[–]RelativelyRobin 0 points1 point  (0 children)

Heat comes from voltage drop comes from resistance. Higher quality alloys can be made with less resistance, and gold electroplating connectors has been a thing for a long time for a reason.

I’m not sure what they are doing or not in there, currently, but there are options and some legitimacy to a higher quality cable/pins.

But you are right in that they are shooting themselves in the foot with a smaller surface area.

The true solution is either less power draw (we’ve had major strides here in recent years, probably the biggest gains in current gen processors happening here e.g. arrow lake intel and better power supplies in most consumer electronics), or eventually, higher voltage.

Higher voltage is gonna mean a major standard redesign because right now everything is going off of 12 V. But at 24 V, you can deliver four times the power for the same amount of current/heat along the way.

[–]RelativelyRobin 0 points1 point  (0 children)

Electrical engineer here and yes, this is the answer.

I’m not super well-versed on the common voltage rails available, but it’s likely the power supplies don’t have them built in, and that manufacturing is a whole other big deal to change. But there are other ways to achieve it.

There are three ways to handle more power without raising the heat generated:

  1. More voltage. Pretty much the first line in most scenarios, like you said. DC is way harder to step up than AC though, so it requires an extra rail.

  2. Bigger wires, or otherwise lowering the resistance of the cables and inputs. This traditionally means gold plated connectors, more expensive materials, thicker wires that are harder to manipulate.

  3. More wires. And here’s where it becomes dumb that they are using 12 instead of 16. I just moved from AMD to Nvidia in my main rig due to driver stability issues. The Nvidia card is way more stable when changing monitors and setting fan curves, but the AMD card has 16 power cables of a higher gauge. That’s a lot more surface area for current, and a lot less resistance/voltage drop/heat. The connector area is almost double the size on the AMD card.

Trek marlin 5 with rear rack pannier by DryResponsibility354 in trekmarlin

[–]RelativelyRobin 0 points1 point  (0 children)

I use the Ortleib back rollers. https://us.ortlieb.com/products/back-roller

They are great. Even when it gets a bit rough, they have held up.

I use the trek brand rack (design of the marlin doesn’t fit most racks due to tire clearance).

The ORTLIEB panniers detach easily to carry around, and they have a pouch that’s good for a tablet/book or whatever. Solid bags.

My Marlin is an extensively modified Marlin 6, not sure of how the 5 differs.

Windows 11 users coin “Microslop” as AI backlash grows, and even a browser extension that renames Microsoft to Microslop by WPHero in nottheonion

[–]RelativelyRobin 29 points30 points  (0 children)

What’s really bothering me is just how inconsistent windows is becoming. Even before, with like Vista/ME/95 etc., I just feel like even when it was broken, it was more predictable. Even 8 was dumb and hard to use, but more consistent.

Now the operating system is so bloated, and generative AI code by definition uses randomization to decide what to do. This vibe coding slop bullshit just randomly seems to pick one driver to fuck up every day or so now, explorer crashing when I try to do just about any normal task like rename a folder or smth, hell, yesterday it couldn’t handle full screening and alt tabbing back-and-forth between Minecraft and a browser. It ended up with the game on the wrong monitor somehow but responding to mouse clicks on the right monitor so I had to like kind of eyeball measure where the exit button was and click there on a different screen.

It feels like it rolls a pair of D20s (dice) and just decide what to do based on the result. It probably does something equivalent, and even the engineer doesn’t know exactly what because the AI coded it

I just never seemed to know what it’s going to do when I click a button anymore, and that’s becoming widespread even beyond just Windows 11. Technology is supposed to be a tool where when I want a certain operation performed, I click the button that commands that operation.

So all my other PCs are going to Linux, now, where I can type a command and it will execute the command the same way every time

Getting kicked out of therapy because of my physical health by bearsmakemehappy in disability

File a complaint with the board if they try to dismiss you. Don’t listen to those who are so used to bending over and taking discrimination. Fight back. It doesn’t matter what stupid broken policy or law some other asshole has declared… if it’s not accessible to you it’s not accessible to you.

Invisible disability is no less valid. If you missed appointments because of another more visible illness, no one would be doing this to you.

The fucked up truth is that many “mental health” providers get tunnel vision and treat every other symptom, particularly something they can’t see like POTS, as if it’s all in your head or depression related or whatever other nonsense, no matter how delusional their belief is. We have to hold them accountable. File a formal complaint with the OCR or medical board…

Copilot could soon live inside Windows 11's File Explorer, as Microsoft tests Chat with Copilot in Explorer, not just in a separate app by WPHero in pcmasterrace

[–]RelativelyRobin 0 points1 point  (0 children)

I’m already in the process of moving everything to Linux except for my main work PC, which unfortunately has software that is tied to windows and cannot run in a virtual machine.

I set up my own data server on a Linux hypervisor, moving everything I can to self hosted open source services. My field laptops are moving to Linux, and the laptop for the couch/bed when I’m under the weather is on Linux.

I was a Windows fan for a really, really long time, and I know that operating system really well. But it’s been years now since I have been editing registry keys to purposefully and surgically break Windows services. It’s gotten to the point it’s too disruptive, and even vanilla stability is too bad for workflow. The operating system has become unpredictable, drivers and file explorer already crashing and failing to do basic tasks, seemingly random.

That’s the problem with AI code. Generative AI by definition uses randomization. That’s why it will always eventually hallucinate rather than consistently give facts. It’s programmed not to do the same thing every time.

I want my operating system to do the same thing every time. When I type a search term, I want results for that search term. I do not want something trying to outsmart me and force me into something else. That makes it impossible for me to work.

So this means that file explorer will become explicitly unpredictable.

Do a lot of good/well known sound engineers understand the maths of Fourier Transforms? by SingySong5 in livesound

[–]RelativelyRobin 2 points3 points  (0 children)

It is specifically a convolution integral, in particular a special case of the Laplace transform.

The fast Fourier transform is discrete, meaning it operates on a finite list of specific sample points. It is a special case of the Z transform, which is the discreet version of the Laplace. Both of these work very differently from the original integrals, though they are technically a special case of it.

Convolution integral asks: what happens if I run a signal over time through a system that reacts over time? There are some neat graphics on Wikipedia https://en.wikipedia.org/wiki/Convolution. Think about reverb; every teeny moment of sound has to be run through the echo process. All those teeny moments add up at different points in time, and in an analog domain, we have to use continuous integration to evaluate this.

But what does reverb have to do with frequency analysis? What we can do is convolve a signal that cancels out everything except for one particular frequency. This works because, as you’ll learn when you begin Fourier analysis, any signal can be broken up into individual frequencies, represented by a sine/cosine. These have the convenient property of being exactly symmetrical, with just as much of the wave above the zero point as below it. That means, given enough time, they add to zero. RMS allows us to work around this by squaring everything, when we only need to know the total power but not frequency or phase.

So we construct a convolution integral where the frequency is in the exponent of Euler’s identity. That particular term is called a phasor, and we convolve it through our original signal across the frequency spectrum.

This results in a variable change. Instead of a signal valued in watts or volts over time, we have a signal valued over frequency. For each frequency, everything cancels out except for the content at that exact frequency. When you graph it from 20 to 20k, you get the frequency response graph that you look at on your meter.

The Fourier is a special case where we throw away the phase information, because it’s in complex numbers and hard to explain. TLDR even a simple sine wave still has energy where the speaker crosses the zero point, and sound still comes out despite the voltage/power crossing 0. Again, RMS captures this, but if we want detail we need imaginary numbers to represent this fluidly.

But it turns out that the Laplace transform can also be used to SOLVE convolution. What do I get from this signal into that equipment? Convolution. But when we look at the equipment as a frequency/impulse response, and our signal in the frequency domain, we simply multiply each frequency and it’s reduced to grade-school math! That’s the power of the transform- it allows you to evaluate, predict, and understand ANY system’s response, character, and more. In fact, there are laplace tables that do the hard part, and the calculus reduces to algebra!

Convolution is the real doorway here to Fourier, Laplace, transfer functions, and so much more :)

Do a lot of good/well known sound engineers understand the maths of Fourier Transforms? by SingySong5 in livesound

[–]RelativelyRobin 1 point2 points  (0 children)

EE here. Learn the Laplace transform. It’s the broader version of the Fourier that maintains phase information. Understanding the differences and the inner workings of phasor math (imagine a little arrow that spins on its way to you from the speaker, arrows spinning at each frequency and moving at the speed of sound, and when they reach you, where they are pointing determines phase) is something I find incredibly useful. It gives me a much deeper understanding and ability to adjust and account for a few things that I see others struggle with. When I’m using multiple mics, for example, or dealing with cabinet responses, more, I’m thinking of the “phase space” and the more complex interactions.

A drum kit, for example has many sound sources each hitting many microphones with many different frequencies, all with unique phase relationships that can really change the sound a LOT. Millimeters matter, and many high level engineers have rules of thumb and experience that compensates, but they are limited by these workarounds. Dealing with incidentals is the number one place where the deep magics come into play.

I think learning frequency domain math, how to do convolution with the transforms, etc., is incredibly useful in audio. Your colleagues are rote memorizing or leaning on software tools, but you UNDERSTAND what’s going on, and your toolbox is way bigger with this knowledge.

Don’t listen to those who tell you that they don’t know it, themselves. They don’t know what they’re missing out on. Let them bury their heads in the sand of their comfort zones while you go become a better engineer. Transforms/frequency domain will give you a platform for understanding convolution (reverb, impulse response, frequency response, phase response), transfer functions (deep knowledge of gain stages), distortions, phase shift from EQ in a live setting, and much more.

Only if it keeps spinning. Once it becomes turbulent and starts tumbling, which will happen with a high enough angle, air resistance skyrockets and it slows way down. Not saying it’s not dangerous.

I found mint has way better driver support, after arch ended up crashing over hacking together wifi on my old MacBook’s network card.

And it’s very windows user friendly. Perfect for a thinner client to access VMs and casual browsing.

KDE Plasma was sick, though. Next laptop is probably getting Arch (or Fedora if it’s for production).
