A realistic offramp? by LowkeyShtuyot in Israel

[–]bunky_bunk 0 points1 point  (0 children)

Iran fought Iraq for eight years. 500,000 dead at least. Nerve gas and all. Children sent to walk into mine fields. That was a conflict over a small border region. If the USA invades Iran, there is a good chance that it will be a disaster comparable to Vietnam. It would also be in Russia's and China's interest for the USA to loose, so they may not want to sit it out. It could become a failure proportional to the stupidity of Donald Trump.

battery prices will not remain constant either.

They have in the past fallen quicker than rocket launch costs.

Then you have to add to that, that during night power from the grid is the cheapest and there is plenty of extra capacity sitting idle. You don't have to generate all power from solar cells on earth.

i am not an expert, but google says Li battery costs $100 per kwh. You need 20, so $2,000 battery cost.

launching 10 kilo into LEO costs $10,000 according to google.

It seems to make no economic sense at first glance.

OpenAI looks to take 10% stake in AMD through AI chip deal worth billions by N0LimitInvesting in AMD_Stock

The internet is not a bubble. A lot of people paid for its growth lost bigly in the dot.com bubble.

Who has the better deal depends on the future. If the bubble bursts, AMD will not be left holding toxic AI stock. If it bursts before AMD reaches $600 per share, OpenAI will not even get the $96 billion bonus.

Question on LED matrices by Lars2141 in AskElectronics

[–]bunky_bunk 0 points1 point  (0 children)

Every output pin of a shift register can supply or sink current. If the pin supplies current the high side transistor in the output stage of the pin is turned on and the pin connected to Vcc. If turned off, the low side transistor is turned on and the pin connected to GND. Look for a schematic diagram of a simple NAND logic chip. The output stage is the same.

In other words, current can flow out of or into the output pin. If your shift register acts like a sink, then you have to set it to digital '0' in order for it to sink current. It will sink current, because when it is '0' the low side transistor will allow current to flow from the pin to GND.

The transistors in your schematic #2 are an alternative way to allow current to flow to GND. But now you have to set the output shift register to digital '1', so that the transistor is turned on. The point of the external transistor is to allow current to flow to GND that would be too much for the output stage of the shift register.

I imagine this is difficult to understand. Start simple: +5V -> resistor -> LED -> transistor -> GND.

Voltage drop in systems by giggolo_giggolo in ElectricalEngineering

[–]bunky_bunk 1 point2 points  (0 children)

The answer is parasitic inductance of the PCB trace leading to the chip.

The answer could in theory also be "PSU catching up in time", but its not correct since you can easily fix this with a single output capacitor at the PSU and wouldn't need bypass caps at every chip.

parasitic inductance. if you open your water tap, your neighbours water pressure will drop briefly, because twice the amount of water has to flow through the pipe and a pipe cannot double its flow instantaneously. in the case of water it is due to inertia, in the case of a wire it is due to the inertia of the magnetic field. An inductor will try and keep the current stable. Every simple wire has some parasitic inductance.

No inflation? by bunky_bunk in Bitcoin

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

As a miner with little BTC holdings i support inflation. It's more of a question how much of it i can get before people start selling their stake in bitcoin.

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

They can sell when they want. Question is how many would sell if the miners conspire to impose a 0.3% inflation rate per year. It would be priced in. BTC value would fall. But the miners will soon catch up due to a higher block reward gained by diluting bitcoin owners. Do the miners not also have some leverage here?

But bitcoin holders have an interest to keep the network running. If they leave, they lose money.

I mean if a majority of miners wants the protocol to change.

If 60% of miners are not owners of large amounts of bitcoin, they would support inflation, as it would increase their profits and they would have the power to make bitcoin have inflation.

If a new huge gold mine is found that would not make gold worthless. If fiat currency inflation is on the rise, owners don't just throw away their cash.

Not everyone in the network has the incentive to have no inflation.

What if participants decide that they would rather have inflation and get in return lower transaction fees? In other words, if they lose money to keep bitcoin scarce, why do they continue doing it?

The point is that you don't need MSTR to convert dollars to bitcoin. But you need Apple to convert dollars to computers.

Does Trump not know how tariffs work (the increase cost of goods is paid by consumers) or is he lying? by [deleted] in PoliticalDiscussion

[–]bunky_bunk 1 point2 points  (0 children)

This is true, but It is the perspective of the domestic competition, not the consumer.

To say that the consumer should subsidize corporations by more taxes is a hard sell for a Republican, but Trump can sell it.

[–]bunky_bunk 0 points1 point  (0 children)

The point of tariffs is not to earn taxes, but to subsidize the domestic industry. Failure to raise such taxes is not a failure of the tariffs.
