Because why spent coal on heating stables for the livestock, if the livestock doesn't die without it?

That's the mentality of a communist dictator.

baybal2··on Apple Procurement VP Departs Company After Vulgar TikTok Comment
The man is very well know in Apple's supply chain, and has a reputation of a used car salesman, nevertheless he is phenomenal at that.

I am speechless they fired a man they been trying to retain at any cost.

I attribute Apple's sound manufacturing operation, and insane profitability to him as much as to Cook.

Absolutely correct, it's a quasiscientific sounding mumbo jumbo

Linux only editions nevertheless makes sense if you want to cut down on the chipset cost.

AMD chipsets have SoundWire, and MIPI CSI/DSI support, but there are no way to use them in Windows. Intel is starting to support them as well with Alder Lake mobile.

SoundWire is way simpler than HDA, and availability/cost is better.

Connecting the whole suite of peripherals over i2c allows to dispose of wide LIF cable from the front panel. No LPC EC needed.

MIPI CSI cameras are vastly superior to USB ones, and are dirt chip for price/picture quality due to the size of smartphone market.

Tablet use MIPI DSI panels price/quality is superior to LVDS panels, and you will never get such thin laptop-use panels.

Linux can use non-SMBus battery gauges, and PMICs. Again, you can forego paying the x86 premium on SMBus vs. i2c controlled PMICs.

> To keep the cost down, the top cover is aluminum-formed instead of CNCed

Forging is in no way inferior to CNC, on the contrary, a forget aluminium part should have more rigidity per unit of thickness, depending on the alloy.

I guess, you got to volumes big enough to open the mould for forging?

If you need an audio engineer, I can refer you one fellow. He worked at Apple, Harman, Asus, BBK, and is now looking to relocated from the East Bloc.

> The other thing is that Apple is trying to make things harder for people with large amounts of resources (think nation states) to exfiltrate data by using pwned components.

Reflashing serial numbers of common i2c chips is routine, and not "harder."

It basically only deters self-taught repair shop owners, without electronics background.

> why can't phone makers make phones with a mid frame that allow both sides to be easily swapped out,

Midframe based based construction was standard for most premium smartphones 2010-2015, after that two piece construction, and "bathtub" took over for economic reasons, and because of MBA people wanting to parrot Apple's engineering in everything.

baybal2··on Aleksandr Sorokin smashes 24-hour world record with 198.6 mile run
I know what you are implying here...

All Russians born in Lithuania been offered Lithuanian citizenship, repeatedly, many times over.

Some Russians on the far right of the political spectrum repeatedly imply the contrary. This is not even a conspiracy theory, but a "being debunked in 5 minutes Googling theory."

> All the hardware is built in. It works for 1500km then stops until you pay up.

So, ABS disengages at 1500kms, and you fall on the first puddle of water? (This is a big, heavy bike)

baybal2··on What brought down Airlift, Pakistan's first would-be unicorn
> That's either investor lie or he's in denial

That will set a very bad precedent. It was a miracle Pakistan's funding ecosystem got so far. India has n-times bigger IT industry, but is not n-times bigger on funding.

baybal2··on FLAC 1.4.0 released – added support for 32-bit audio
Microchips are cheap, once initial investment is made. I guess, it only costs ~10¢ for new SoundBlasters at 90nm-130nm.

The price of 10 sound cards will be enough to pay for a whole wafer.

baybal2··on How Transistors Work [video]
> for greater currents the BJT is more efficient

Depending on voltage. Extremely low RDs ON FETs are there. The real world choice would depend on whether you just need a constantly open switch, or high frequency switching for power conversion.

Are you in power electronics?

It seems it was in plans for a long time undetected, but then they committed to enforcing it when Jio took off.
baybal2··on An enthusiast’s deep dive into mechanical keyboard switches
Mechanical switches are by no definition impossible to make bounceless.

SPDT pushbuttons with both outputs wired through a D-latch are perfectly bounceless.

baybal2··on Tell HN: My phone just told me to check for moisture in the USB port
> I didn't know phones did this nowadays. I wanted to share it with HN in case anyone else is surprised by it.

OPPO invented this when they started deploying VOOC charging (serious current,) standard Android has since copied it.

They measure the resistance in between data pins periodically. If there is no voltage, but resistance is low, they show this alert.

baybal2··on How Transistors Work [video]
> In fact, they invented a new part that has the "input" gate of an FET and the Collector-Emitter "output" of a BJT!

IGBTs are far from being a new invention.

And if we are speaking strictly, very high currents aren't switched with higher net efficiency by BJT than FET.

The reason SCR type devices are used for the kiloamperes range switches is due to them being the only switches which can mechanically/thermally handle so much current.

But for high voltages, bipolars will indeed go higher than FETs.

baybal2··on Why are Pakistan’s floods so extreme this year?
Because rains been going on for so long this years. Heavy rains went for 2+ months so far across different parts of the country.

Way longer that 1-2 weeks intense monsoon downpour.

baybal2··on Mikhail Gorbachev has died
Russian citizen here, and one with enough self-honesty to talk about 199X without selling self-pity, unlike my compatriot here.

> The United States didn't do enough to help Russia transition to democracy in the 1990s. There was no "Marshall Plan" after the Cold War like there was after World War II.

Total bullshit. The West did put in nearly as much money as part of GDP in aid to early 199X Russia as US did in Europe after 1945. US aid was pouring from every hole up until mid-late nineties.

I would argue America went too much Marshal on Russia, and you are reaping the results of this folly now. It was a giant mistake not to finish off the beastie, and not to SCALE UP the pressure after the USSR collapse to force genuine reforms.

The West is responsible for much of CPSU's comeback happening in 200X, repeating how USA saved early CPSU from total collapse from food riots in early 192X out of pity. A giant mistake.

US humanitarian aid was stolen many times over, sold again, stolen, and resold, giving a headstart to CPSU elements turning to banditry. It was totally unsupervised. US totally failed to empower the right kind of people back then with its aid.

Subsequent entries by Western multinationals funded much of 200X mess in Russia, rise, and legitimisation of early Putin's mob regime. The first Western supermarket in Russia was literally inaugurated by the mob boss of Moscow.

Much of Kremlin's current denizens owe their meteoric rises to megabribes they got from Western MNCs in early 200X, which they used to fund their political ascensions.

------------

Other post-USSR countries which did have their economies opened up, and claimed by the Western capital yearly on were super lucky to have the West "rob" them like that.

Russia, or Central-Asian states were saved from such "robbery," and their economies at large stayed with the CPSU mobsters instead.

------------

"Russian Liberals" == Total intellectual dishonesty. They share as much the blame for Russian devolution into North Korea 2.0 as Putin himself.

> short stick (like my parents, who lost their jobs, their city apartment and who had to resort to literally subsistence agriculture in a matter of 4-5 years maximum;

Good for them! They did live in apartment, unlike the 80% of Bloc's population, who lived in wooden barracks from fourties. They likely had a white collar job, and been on good terms with communist authorities.

Not living in an apartment for 5 years is by far not a life breaking event, nor is anywhere close to worst shit happening to less elite people back then.

baybal2··on Amid chip shortages, companies bet on RISC-V
I found it to be completely orthogonal how switching to a different ISA will solve the issue of lack of underlying physical semiconductor manufacturing capacity.
baybal2··on Vietnam to make Apple Watch and MacBook
95% of Vietnamese support capitalism: https://eu.usatoday.com/story/news/world/2015/03/13/vietnam-... thus making it the most capitalist country in the world...

Second in line is Bangladesh

P.S. USA had a capitalism approval around 70% in the same survey.

baybal2··on Google IoT Core will be discontinued on Aug. 16, 2023
Exactly, everybody who bet on Google in IoT has just got a giant RMA bill.

Same has happened when Azure changed its root cert, which was likelly hardcoded into 99% of deployed devices using it.

baybal2··on Tell HN: Apple products come with ungrounded plug in India
This is only allowed with an Y rated safety capacitor in most countries, or not allowed at all.

Fake, or genuine, but still bad Y caps are everywhere.

baybal2··on Tell HN: Apple products come with ungrounded plug in India
> If you feel an electric shock from touching the MacBook while plugged in, there's a fault in your electric system.

It means isolation on the charger is faulty.

A properly working modern charger should not have any galvanic connection to the grid.

The isolation transformer is likelly to be defective.

baybal2··on TSMC: N2 to Start with Just GAAFETs, Add Backside Power Delivery Later
Making multilayer nanosheets means O(n) additional multi-patterning imaging steps. 1x for each nanosheet layer. This is what is possible with current "bruteforce" approach.

A nanosheet device will have to get thicker for an equal performance to FinFET if they want to keep the number of layers sane.

This is why it's accepted that first generations of multilayer GAA devices will be inferior to FinFETs of equivalent density.

Everybody is of course searching for how to do multiple nanosheets with single imaging step.

20 years old experimental nanosheet designs won't do it in production today. I.E. cutting multiple sheets with RIE is way too coarse, and destructive for modern feature sizes. Depositing sheets into a negative pattern on a sacrificial poly layer brings alignment issues.

baybal2··on Debugging bare-metal STM32 from the seventh level of hell
STM32s are actually very nice things to debug by the standards of the embedded scene.

At least 1 set of stm32 cube tools will be always working.

It's not uncommon for microcontroller vendors to not to provide any tooling at all, and just say "Use JTAG" without any further explanations.

And then JTAG may, or may not work. Or only work on some decade old 3rd party IDE + 3rd party USB (or even RS232...) JTAG debugger + pre sp2 win xp version combo.

baybal2··on US has lost at least three nuclear bombs that have never been located
And Russia has lost 20+ 152mm tactical nuclear weapons over years.

Then one day, suddenly all of them were declared "found" somewhere around 1998-1999.

My bet USA just annoyed Yeltsin enough to put up a pretence solution.
