baybal2··on Apple dives into display-making to cut reliance on Samsung
Apple for long time tried to buy JBD Display, they sent their due-diligencers, which inspected everything millimetre by millimetre, and then poached their process head.

JBD then armed itself with lawyers, and for long tried to frustrate Apple from reproducing the technology.

baybal2··on Ukraine downs Russian hypersonic missile with US Patriot
It can't afford to. It will be instantly recognized as an admission of weakness in the snake lair.

For as long as Putin's regime stands, klepto elites around him will be sure that, at least within Russian borders, they are still kings, and they can live the rest of their lives surrounded by long legged mistresses, and drowning in luxury.

If Putin is seen as weak, any small time gang will think that moneys, and power of Russia's top oligarchs are for grabs. It will be then, when a preemptive coup attempt can happen.

baybal2··on The magic of DC-DC voltage conversion
> but it also has led to complications with power supply ripple showing in ADC readings.

High-end MCUs used to have separate voltage inputs to ADC, for power, and voltage reference.

Older ATX power supplies actually had very high quality 3.3V and 5V outputs because they were coming from linear regs.

I remember some USB gadgets were working in some mobos, but not the others depending on whether 5V was wired from the ATX power, or not

baybal2··on Ask HN: Why is TSMC so competitive in semiconductor fabrication?
Because they took upon a very hard task, and kept punching it year, after years, through, low margins, highly cyclical market, extremely low returns on capital, tricky clients, and a marathon like RnD expenditures.

They are the leader because everybody else dropped out, and went to make money on something easier, like making Wordpress websites.

baybal2··on CATL has announced a new “condensed” battery with 500 Wh/kg
Battery people keep comparing apples, and oranges.

Battery pack energy density, battery, single cell, cathode, and their rated, nominal, and absolute capacity are all different things.

A single cell will always have > absolute capacity than the capacity at which the safety limiter will cut-off charging, and that will be > than the capacity to which BMS will charge/discharge the cell in daily use.

It may well be possible for a cathode material to excel in a small pouch cell, but have terrible thermals preventing its use in larger cells.

baybal2··on Lithium battery ripe for disruption, inventor says
I want to underline, it's not about any other chemistry overtaking lithium he is talking.

Lithium will almost certainly remain the one, and only mainstream battery chemistry simply because of physics. Lithium ion has the lowest mass per unit of charge.

It's about cathodes, and electrodes which may change, as well as their manufacturing technology.

baybal2··on Nvenc vs. QSV: Who Has the Best Hardware AV1 Encoder?
I was recently asked why so few chips support decoding AV1 in hardware.

There were multiple mutually incompatible AV1 versions early in development, and some companies chose to not to implement either until the situation settles down.

But by that time X265 was already deployed en masse in the wild. And now X266 is about to take over.

Many will chose to leapfrom AV1 straight to X266.

baybal2··on Intel Foundry Services and Arm announce collaboration on SoC design
> The collaboration will focus on mobile SoC designs first, but allow for potential design expansion into automotive, Internet of Things (IoT), data center, aerospace and government applications.

Take a note on the wording. They are definitely making a mobile SoC for somebody, with Qualcomm being the likeliest client.

But then they instantly dilute it with other buzzwords, and try to break the line of thinking how it will compete with Intel's own products.

baybal2··on Intel Foundry Services and Arm announce collaboration on SoC design
Non-touchscreen smartphone boom been going for years prior.

The problem was that embedded OS-es like Symbian, A200, PalmOS were running circles around Windows Mobile. Most of them used Samsung SoCs which were few times slower than StrongARM.

StrongARM was seen exclusively in the context of it being used to "lift" extremely bloated WinMo smartphones, and was otherwise thought as an overkill for other uses.

baybal2··on Last-gen ultralight laptops are nearly as fast as new models–and much cheaper
There is currently a huge inventory crisis across laptop brands.
baybal2··on America is back in the factory business
Depending on what you are manufacturing

Plasticky goods probably yes, but for electronics assembly, it's already USD 2500 a month for a good experienced assembler.

baybal2··on Japan Breaks with U.S. Allies, Buys Russian Oil at Prices Above Cap
> Japan should move to withdraw from the Sakhalin projects eventually “if they’re really serious about supporting Ukraine.”

What an irony. Japan has to buy its own oil from Russia, from the island Russia seized from Japan.

baybal2··on Leaving China
The fallacy of "reformed communism" hopers is that with development came not their hoped reform, but even stronger regime, and harder life.

Way more, many times more rich Chinese are fleeing China now, when it reached some level of wealth, and industrialisation, than back 10-15 years ago, when China was incomparably poorer, and everyday life was incomparably harder.

All of that was easily predictable. You have a terrible regime, you give it money, and power. It only becomes stronger, and more terrible, not less.

Communism is irreformable.

baybal2··on Leaving China
I've been working in, and out of South China since 2009, and have called it quit 2019, when it became clear the industry was done for, and CoVID mess only reinforced my decision.

I never held any fraternal feelings with the country, even though I am ethnic Chinese, nor I had any delusions about making long term plans there.

In my years there, I kept seeing rose coloured glasses wearing American expats. I met Tim Cook during his first travels to China as CEO at some random event in Shenzhen, only to see him regurgitate the official drivel.

Since around 2016, I kept seeing more and more Western high flyers coming to official events there, seemingly trying to network with locals, and only to see them freak out at that.

My regular conversation with them:

- it's a damn communist regime, do your business and get out

- no, it's different! there is no more communisms in China! no, it's state capitalism! no, things will change! no, I have a special plan from EY China expert!

Most of them lived there for 2-3 years, and got out just as I told when the truth hit them. In the end, I outlived all of them there.

China is a communist regime, though a very well doing for some years.

baybal2··on Tons of uranium missing from Libyan site, IAEA tells member states
But it will be enough for 50kg of plutonium even with most primitive reactor
baybal2··on Scheele’s Green, the Color of Fake Foliage and Death (2018)
Lots of other modern dyes are quite poisonous as well, and are not banned even for things like toys, or foodware.

Lead oxide for example only got banned in the most of the world in 200X, with countries copying EU's ROHS regulations. Chromates are well known to be cancerogenic, but are only about to be banned in EU.

All bright red cars manufactured after nineties have to use organic red pigments, which fade very fast, in comparison to chromate or lead pigments, that's why there is such huge monetary interest in finding a new inorganic bright red pigment.

baybal2··on Russian Assets Reportedly Seized at Baikonur Cosmodrome by Kazakh Authorities
The land there is leased, but Russia have to pay annual fees for property of Kazakhstan on the territory separately.

Cases of Kazakhstan seizing something there because of late utilities payment happened before.

baybal2··on AMD Instinct MI300 Data Center APU – 146B Transistors, Shipping H2’23
Flash memory chips have passed 1 trillion long time ago.

The first one was a 512GB Samsung flash chip

baybal2··on Nokia launches DIY repairable budget Android phone
I worked for a client in 2019 which wanted to make something similar to what Nokia is doing now.

They wanted a barebones, no effort to catch up to top competitor phone, with more practicality, and everyday convenience in mind than putting in 10ghz CPU inside a phone.

We went for a year, and bang... Google probably seen client's PR, and banned Android phones without a superfluous gycoscope/accelerometer/etc stuff. We spent close to year on it.

I was fuming.

baybal2··on Blowing holes in Seymour Hersh’s pipe dream
Abu Ghraib happened, and My Lai happened, and Hersh was first who brought these two stories to light.

Neither were some giant secrets, and were previously dismissed as unsubstantiated rumour. Hersh collected enough factoids together to substantiate them enough to become a news story, rather than a military legend.

baybal2··on Gigapresses – the die casts reshaping car manufacturing
It's unrelated, that's the thing.

IDRA's "press" is a casting machine, not press forging.

baybal2··on Gigapresses – the die casts reshaping car manufacturing
Explaining, the "gigapress" is not a press, it's more of an injection moulding machine for aluminium. That's the biggest outrage.

This is the real metal press: https://youtu.be/iZ50nZU3oG8

And what Elon called a "gigapress" is also not related to more familiar semi-solid metal casting, as the alloy used has no thixotropic properties, but more regular casting under pressure.

baybal2··on Shoichiro Toyoda, who turned Toyota into global automaker, has died
Toyota wasn't first.

But it was them learning a lot from working on looms, and other stuff at textile mills taught them how to max productivity.

Textiles making was already a very competitive industry in late 19th century, and the only way to push forward in productivity after looms were optimized to the max was to cut slack in between machines — management techniques.

There the manufacturers were stealing each other's ideas "within months" as Japan had no enforceable Western style patent system yet.

The electric andon was for example copied from Suzuki looms, where it prevented looms from dethreading when the machine runs out of thread, and requiring hours to manually rethread it again.

Stopping the entire mill for a few minutes to recharge a loom begins to make much more sense when you understand that the alternative is to stop it for hours.

baybal2··on Videos show Turkey's Erdogan boasted letting builders avoid earthquake codes
Erdo, and AK ratings have tanked so hard already that there is no chance he will be winning anywhere fairly at all.

Now, the question is whether will he go for electoral fraud, or leave his post knowing for sure that a jail term awaits him.

baybal2··on “How America took out the Nord Stream pipeline”
And he also claimed that Moraji Desai was... an American spy.

The guy is obviously picks up lobby chatter, and lets his imagination to run.

My Lai was never a giant secret, he was just the first to bring it to the wider audience.

baybal2··on Pakistani gov degrades Wikipedia connections due to blasphemy
Some context here.

There were a series of large scale terrorist attacks in Pakistan recently, with recent killing 101 people.

This has caused an extreme level of criticism of the government, and the government is trying desperately to find a way to do a diversion.

Ban on Wikipedia is a highly visible attempt to distract Pakistani literati class from security issues.

Nothing to do with religion

baybal2··on Why Finland Selected the F-35A (2021)
There are thousands of S300*, and Buk missiles in stockpiles of both Ukraine, and Russia.

Enough to shoot down each other's airforce a few times over.

baybal2··on Why Finland Selected the F-35A (2021)
> Ukraine has repelled Russia very effectively with just manpads, ATGMs and NATO intelligence.

Ukraine has effectively repelled Russia because it's the second biggest military in Europe after Russia, and second strongest air defence in Europe after Russia.

This is the sole biggest factor without saying which, everything else is meaningless.

baybal2··on What happened with the substation attack in North Carolina?
It's not the radiators, it's the transformator itself.

Shorted winding == complete replacement needed for high voltages, and a single bullet would be more than enought to break insulation on the winding many times.
