azubinski··on Did pizza exist in the Soviet Union?
Definitely not.

The reasons were the chronic lack of wheat, especially hard varieties, lack of milk and cheese producing culture and technologies, lack of fresh vegetables and culture and storage and logistic technologies, lack of meat, lack of customers, lack of common sense etc.

Who needs pizza when you can stand in line for six hours and buy a blue chicken carcass consisting of bones and bones?

It's not the answer to the question that's interesting, but the questioner himself.

azubinski··on People person: the greatness of Andrey Platonov
Unfortunately, Platonov could not stand the torture and in the second half of his life turned into a de facto mouthpiece of the regime.

However, he was not the only one, and in the end there were no others at all.

In any translation, his texts lose their meaning; now he is interesting only as another example of the work of the totalitarian selection of the “new useful people”.

Nothing.
azubinski··on Diffractive Chocolate
It is obvious that if you correctly add pieces of something like this to a viscous medium (so that the pieces are on the surface of the medium), you will get a viscous material with a visually observable diffraction effect:

The other thing is unclear:

Why gnaw on diffraction sheets?

Will this make chocolate taste better? Will this improve your health? It's all very exciting and mysterious.

azubinski··on Exploring TrustZone-M on the NRF9160
But it's just Cortex-M33...
azubinski··on Exploring TrustZone-M on the NRF9160
"So of course I opened the big bad search engine and typed Nordic nRF9160 bare-metal example. I quickly learned that, while bare-metal programming Nordic boards is possible"

Google, of course, is very big, angry and bad, but there is no need to search for what is on the manufacturer’s website:

azubinski··on Ask HN: Going low-level – what to learn next?
Low level is mostly not about processing core even if you are using assembly language. Yes, you can reach guru level in assembly language of some target platform but to do something really useful at the lower level you need to know and be able to use the peripheral.

And the hardest things are in peripheral.

Any modern microcontroller it will give you the opportunity to learn a lot of useful things about peripheral devices. You can start with any really good modern 8-bits micro like Microchip's 2nd generation of ATTiny, so you'll have in your hands a lot of very powerful interesting smart peripherals: hardware event system, small programmable logic, different timers, good ADC etc.

The only rational additional consideration here is that your target platform should be popular, well documented and supported by the manufacturer.

Then will be time for some Cortex-M0 device with DMA.

Then you'll decide where to go further :)

azubinski··on Parable of the Sofa
Well, it started with:

"So we had them replaced, at a fair price, by a small local business. Which is something that modern capitalism is trying to make impossible"

And then there was lot of blah-blah-blah about small local business which thanks to those "modern capitalism" is possible and exists. But what is "fair price" is still unknown from whose point of view it is fair.

So, let use the same style (it is the style, yeah):

If you want to rise popularity of your blog in many modern capitalism countries, always start any blog record with any form of modern capitalism blaming :)

azubinski··on Orcas Just Sank Another Yacht
Orcas are not orcs, orcas have a biological nature.

It's just that sometimes orcas don't like yachts :(

This is explainable and understandable at least.

azubinski··on Autonomous F-16 Fighters Are 'Roughly Even' with Human Pilots
Finally some really cool news.

Especially since this is a dogfight and not an air-to-air missile exchange.

azubinski··on Big Fridge
CA (controlled atmosphere) is relatively old multidisciplinary science, practice and huge businesses today.

https://en.wikipedia.org/wiki/Controlled_atmosphere

And, yes, thanks to CA fruits and vegetables are really fresh at shelves, because a CA is about controlling of natural processes of ripening. Till CA adoption USA imported about 90% apples out of season. Now less than 5% only.

It's one of the greatest invention and applied science over the past 100 years.

azubinski··on Telegram has launched a pretty intense campaign to malign Signal as insecure
Life will be much more boring if we cannot find humour even in the most boring things.

So, it's good that the personal involvement of the illustrious Elon turns even obvious political influence operations into a circus with talking horses and scary clowns.

It's good :)

azubinski··on Why the CORDIC algorithm lives rent-free in my head
Most important keywords are:

BLDC + motor control + sensorless

CORDIC is a de facto standard algorithm in the relevant application area.

Infineon explains algorithms compactly and clearly:

Microchip gives an idea of where and what the algorithm is used for:

CORDIC hardware accelerators are found in many microcontrollers designed to control electric motors.

azubinski··on DIY YouTuber Builds His Own 256-Core RISC-V Megacluster at 14.7 GHz 1-Core Freq
Mega- scale means something more than 10^6.

256 means 1/4 of kilo- only.

Cluster? A cluster is basically anything. Take 100 bricks and stack them nicely, it will be a cluster of 100 bricks. But it won't even be a barn.

It's boring, girls :)

azubinski··on Kardashev Scale
A completely normal theory for a culture that determines the degree of development by the amount of available hydrocarbon mixtures (natural gas and oil).

There is no point in hating such nonsense, but it is worth fearing.

azubinski··on Automated integer hash function discovery
OMG, is it finally something useful, not in Rust for RISC-V?

I saw at the top in the comments "Skeeto is a legend", this is the best compliment.

My sincere gratitude to the author.

azubinski··on How to improve the RISC-V specification
"Conclusion The RISC-V architecture was developed in classic startup/academic style: innovating quickly and avoiding too much investment in long-term engineering"

But this is not a conclusion in any sense. This is the premise of the entire RISC-V project. Because RISC-V is just an abstraction to teach and learn machine-level aspects of programming regardless of the specific processors available on the market. Donald Knuth has the same, MMIX. In addition it is difficult to say what innovations there may be in the RISС processor instruction system.

Well...

azubinski··on Rust for Embedded Systems: Current state, challenges and open problems
Rust has a single real big problem - Rust adepts still believe in the silver bullet.

For professional embedded programmers, faith in silver bullets disappears with the growth of professionalism.

azubinski··on The unreasonable effectiveness of i3, or: ten years of a boring desktop env
If your toolbox (dictated by your profession) is slightly richer than console applications, you automatically dealing with the applications which are natively "tiled" inside the application windows. And you work with maximized windows of your main applications (natively "tiled" inside) and with a set of small applications that you need to access periodically and these apps do not require full screen mode.

You can alt-tab between them on a single screen, you can switch or swipe virtual desktops with them, you can do anything, a result will be the same.

There are no advantages because of this sameness.

azubinski··on LG washing machine sending 3.7GB of data a day
I just wonder which of LG's competitors ordered this nonsense.
azubinski··on Temperature-sensing stirbar with RFID
There are single chip NFC interfaced temperature meters of course.

azubinski··on Someone bought 26.9 BTC on Binance and sent it to Satoshi's dead wallet
This is the absolute of virtuality - everything is letters and numbers on a screen, but you still don’t have any spoon, Neo, because there is no spoon at all.

Yep, fingers are fat for sure, but the sense is different, it's a kind of fat greasy meat fingers.

azubinski··on Vertical farming company raised $500M, and then it all but disappeared
I used to call a flying taxi and fly to a vertical farm for fresh strawberries.

Well, what to do now?

azubinski··on Apple cuts off Beeper Mini's access
First you need to infantilize them to the level of “I’m ready to do anything to be in their gang.”

But at the same time, you need to feed snobbery so that you get a safe mixture of 80% immaturity and 20% snobbery.

Let’s add two drops of self-deprecation, that boring feeling of “I don’t have blue bubbles, I’m worthless and a loser.”

And now you can take a large bag for money and leave it open - they will fill it themselves, tie it and send it to the address :)

azubinski··on Apple cuts off Beeper Mini's access
This is the first time I've heard that people who put features above friendship are called friends.

Well, the time has come.

azubinski··on Ask HN: I learned useless skill of prompt engineering, how relevant will it be?
Let's be precise in definitions and start with the obvious "it's not an engineering at all".

Moreover, according to the ECPD's engineering definition (or to an any other commonly accepted and accepted by the engineering community definition) those fancy "prompt engineering" is pure anti-engineering at all.

This disdain for engineering is something of a tragedy. And it is also the result of the "washout" of engineering from post-industrial societies.

azubinski··on Larne Craigyhill bonfire: 17000 pallets (2021)
It’s even a little pity that this wild senselessness was so rushed.

After all, it was possible to time such a large symbolic burning of logistics for the Elbakyan's EFF award.

Because The Absurdity must be brought to the limit.
