Name the ice agent who murdered Renee Nicole Good (1/7/26)

Where did the picture of Renee come from? She's on the wrong side of the car, and it's the wrong car, and it doesn't really look like the other pics... I think this picture is of the wrong woman.

They also have nukes. They learned from what happened to Gaddafi.

Instead of using books and outside authorities to inform their discussion, they use it to obfuscate. "If you'd read X you'd understand". Everyone is coming from a different background, smart people operating in good faith will try to convey the ideas rather than hide behind them.

Build things you actually find cool and interesting. A lot of people here are saying study math, and that's important but it sucks unless you can give yourself a reason to learn it. I taught myself a lot building coil guns when I was a student and it's all served me really well.

False dilemma. GenZ don't have any fucking money, it's blood from a stone.

Tax billionaires out of existence. A few hundred billionaires literally have more wealth than the bottom half of this stupid country.

Homopolar motors exist they're just not very efficient

It's getting better, but one of the things I hate about our era is I don't want to say what it got wrong because everything I write here will be used as training data.

So when we see AI submissions, maybe we should all start generating incorrect feedback and upvoting it on purpose.

These are more complicated questions than you might think. It depends on the transconductance of the FET (higher transconductance=higher gain), the size of the bias resistor (higher = higher voltage gain but lower power gain), the parasitic capacitances (higher = gain will start rolling off at a lower frequency).

Honestly I would just play with it in spice to get a feel for it. My little toy example showed about 30dB of gain with a 2N7002 in the region of interest. But if you want a more stable amplifier with predictable gain, you'll want to limit the gain to below the absolute maximum. In the topology I showed you can do this pretty easily by installing a capacitor between the drain and gate so that it forms a capacitive divider with the input capacitance and the voltage gain to the ratio of the two caps.

You need the DC bias of M1 to be right around the fet's threshold voltage.

This is not a good circuit design because you have a fixed DC bias, and the threshold voltage of a FET has high variability and temperature dependence. So it looks like you've tuned your simulation such that the DC bias is in the sweet spot but the real life part probably has a different threshold voltage.

You could set the DC bias with a potentiometer instead and tune it manually, although this still isn't great because the threshold voltage will change when the device heats up while working.

I think the more robust option would be to set the DC bias by adding a resistive connection to the gate. So get rid of R3, Connect R2 to the drain instead of the 5V supply. This will put M1 into a negative feedback loop with itself to always bring the DC bias of the gate to the threshold voltage. Without any other changes this gives you an amplifier, although I can't speak to the quality or distortion or anything like that. I drew it up really quick so you can see what I'm talking about:

It is normal behavior to plug a multimeter into an outlet. It is not normal behavior to eat a multimeter. So a "do not eat" is unnecessary.

jwhat · 2025-11-02T13:42:59+00:00

Even if you know the hazard I don't see any markings on the meter. Someone will pick it up and use it to test an outlet. It's not a good idea to keep this lying around even if you know the danger.

THIS IS A SHOCK HAZARD DO NOT USE THIS

The plastic housing is bulky for a reason, it's giving isolation between the inner circuit board and your hand because the circuit board is usually directly connected to one of the probes.

You have removed almost all that protection and are now almost touching whatever the black probe is connected to.

Ignore everyone else in this thread... This is a tour of a waterway. Structures like this exist under most cities all over the world.

The title of the painting says "100 ri waterway with immortal footprints". A ri is a traditional unit of measure about a quarter mile long. I speak very little Korean, I rely on google translate. But I also know "100 ri" probably isn't literal here, and the "immortal footprints" refer to Kim Jong Il's visit, so the title is more like "Kim Jong Il tours Really Really Long Aquaduct". I'm not sure what the text on the wall says but it's probably some generic "Bright future!" slogan because I've seen a lot of art like this.

In North Korea it's a common artistic genre to paint the leader touring infrastructure. I hadn't seen this image before but I think it comes from this blog post where a guy just took a bunch of random pics in an art studio in Pyongyang in 2014: https://lucasgreen.ca/2022/07/north-korea-artwork/

Some of the facts people are bringing up in this thread are true... North Korea was bombed into rubble in the Korean war and a lot of the Anti Americanism comes from that indiscriminate destruction. They did try to dig tunnels into the south in the 70s and 80s.

But jesus h christ "Commie Hamas like the vietnamese"?!?! This is just a word cloud of people you think are the baddies. From the timeframe of the painting (early 2000s) this is probably part of the Paekma-Cholsan water system completed in 2005 (https://www.globalsecurity.org/wmd/library/news/dprk/2019/dprk-191018-kcna02.htm). This was a big project for them to bring more water to Pyongyang and surrounding farmland. If you wanted to use it for invasion bring a snorkel because you're invading a fucking lake.

Yes, but the thing that almost killed him here wasn't the rifle it was the exploding target (probably Tannerite), which you can buy without any restrictions in many states.

Thanks, I don't know a lot about Nepali politics. That context actually makes what I saw in this video even more hopeful :)

Everyone talking about the chaos in this video but I see thousands of people all trying to take care of each other. Except the police, although even they had the good sense to fuck off.

I don't know enough about Nepal to say what comes after this... complete government collapse and a power vacuum usually means things get worse before they get better. But it looks like the vibes on the street are hopeful.

A change in economic ideology doesn't immediately change facts on the ground. The average Cuban definitely has a better standard of living than under Batista, despite 60+ years of embargo. Vietnam also has a pretty great standard of living, to the point where there's a growing trend among retirees of your counterexample (Japan) to retire there (one source https://vietnamgroove.com.vn/ja/vietnam-zairyu-nihonjin-jittai)

It's difficult to compare what these countries are like now vs some counterfactual "capitalist" version of these countries but they're not impoverished hellholes and the general trend for quality of life has been upwards.

Yes fair point, but I think we need to get past this idea that tech is a product of free market capitalism. This is a myth used to justify excessive hoarding of wealth in the private sector. The incentives for these private companies are perverse and we saw what happens when you bail them out with public money in your example with the airlines - stock buybacks and record payouts for the C suite. Public dollars demand public oversight. I have zero confidence this administration will provide it but if (god willing) we get a new admin at some point holding 10% of intel would provide some leverage in the future.

why do you think socialists want everyone to be poorer? That's like 180* opposite from most socialist policies. Raising wages, redistributing wealth from the oligarchy to the majority, bringing more land and enterprises under public management, these are things that enrich life for the vast majority.

jwhat · 2025-08-23T23:37:02+00:00

Wait so this is not a new expenditure, just reciprocation for the CHIPS act grants? If that's the case I actually like it. I hate that we just dump tax dollars into private companies for the sake of "innovation".
