miga··on FSRS: A modern, efficient spaced repetition algorithm
I missed comparison to earlier repetition equations like SuperMemo. Is there any hope for comparison and reference, or will precursor be forgotten?
miga··on Got fed up with 36 hours of weekly meetings. Built something to fix it
Sounds like Calendly on steroids: when do you release SaaS or open source repository?
miga··on The One Billion Row Challenge – .NET Edition
Anybody would host a language-agnostic comparison?
miga··on AMD budget GPU listed with twice memory of RTX 4060, RX 7600 XT with 16GB GDDR6
Most power in a computer is spent on a bus. Most power within CPU is spent on internal bus and memory access. This interconnect between framebuffer and accelerator would limit the speed and eat lots of power, unless the framebuffer would be replicated by GPU during rendering.

That is why GPUs normally have a small part that serves as framebuffer, but memory bus is shared with the accelerator that needs it most. Cheaper to reuse the expensive part.

miga··on Top Russian court bans LGBT movement as 'extremist'
<joke>

Does the Russian court believe everybody is vaguely pansexual, and narrowing oneself down to a single sex is "extremist"?

Are the straight families "extremist" only when faithful?

(I guess they are, but only if they protest against Special Operation.)

</joke>

miga··on Ransomware Group Files SEC Complaint over Victim's Failure Disclose Data Breach
It is logical for the ransomware (or any lawbreaker) to minimize lawbreaker in order to reduce risk and penalty.

It is also a legal act that may be considered to mitigate the guilt in the eyes of the court. Much safer than actually releasing the data.

Why did other ransomware gangs did not think of this first?

Is it because they are irrational or just lack proficiency in the law?

miga··on Haskell WebAssembly in the Browser
It is nice to live in the future "when browsers do not include JS any more".

I do not want to steal your greatness when you port basic JS APIs to Haskell WASM.

Or that of WASI work, when we no longer need to use raw JS API.

miga··on Absence of superconductivity in LK-99 at ambient conditions
Look for Yttrium-Barium-Copper oxide that superconducts when cooled with liquid nitrogen. This is "cheap" cooling that will never run out.

miga··on Replace peer review with “peer replication” (2021)
Peer review does not serve to assure replication, but assure readability and comprehensibility of the paper.

Given that some experiments cost billions to conduct, it is impossible to implement "Peer Replication" for all papers.

What could be done is to add metadata about papers that were replicated.

miga··on Why ISO was retired (2021)
Since observing a SquashFS image outperforming others when doing PDB database processing, I await Linux boot images to all switch to compressed read-only filesystems.

Kernel image files already use bzimage for a long time.

That would make it boot much faster, and use less memory than ISO:

https://blog.sigma-star.at/post/2022/07/squashfs-erofs/

First step of system installation on Ubuntu (Debian) is uncompressing the filesystem. Why not use compressed FS for this purpose too, and shorten the whole process to few seconds?

miga··on Hearing aids may cut risk of cognitive decline by nearly half
This adds to compounding evidence that cognitive decline (including dementia and Alzheimer) is significantly delayed by mental stimulation.

Hearing is just part of it.

miga··on The Pacific Northwest Tree Octopus
There is enough spam here, please avoid posting this one.
miga··on New study reveals most classic video games are unavailable
Last call for preservation of our video game history.

Right to preserve our culture should be enshrined in law, because otherwise it will disappear due to adverse relation with copyright law and novel art production.

miga··on A physicist who bets that gravity can’t be quantized
Why would gravity behave different than Higgs field?
miga··on More than 75% of Steam games tested are playable or verified on the Steam Deck
If more and more games are tested and verified on Steam Deck, why less and less games are playable under most recent version of Ubuntu?

Since I upgraded to 23.04, most of Paradox and many others refuse to play.

Is it something that Ubuntu broke, or a different Linux kernel that breaks OpenGL?

miga··on Canada’s new tech talent strategy
Singapore has public housing corporations that build the high-rise housing for this reason.

Given that Canada is more spacious, government expects free market will solve the housing.

miga··on AMD Introduces World’s Largest FPGA-Based Adaptive SoC for Emulation
What about upload time?

Is it possible to upload just a small bugfix to bitstream?

miga··on Linux Namespaces Are a Poor Man's Plan 9 Namespaces
Try to implement Docker in Plan9 using this tutorial: https://akashrajpurohit.com/blog/build-your-own-docker-with-...

Wonder how far will you fare, and how long will it take.

Or try PlanD: https://github.com/rvs/planD

miga··on Lactoferrin alleviates Western diet-induced cognitive impairment
At 500mg/kg of body weight, it is equivalent of 300L of cow milk for an adult male.
miga··on Lactoferrin alleviates Western diet-induced cognitive impairment
At 500mg/kg, the recommended dosage for adult male would be about 300L of cow milk per day.

At this dosage, seawater may be lethal :-)

miga··on EU Advocate General: Technical Standards must be freely available [pdf]
I think "bad" is understatement: the secrecy of the law undermines the principle of transparency that makes law work.
miga··on EU Advocate General: Technical Standards must be freely available [pdf]
The standards are often referred to by the law and public institutions.

This means that they become de facto law, even if they do not adhere to fundamental principles of the law: transparency, and fairness.

Standard paywalls thus should be seen as a barrier for the rule of law, not just barrier for innovation.

The prices for access to standards made sense in the era, when every document had to be printed instead of downloading as PDF.

miga··on Linux Namespaces Are a Poor Man's Plan 9 Namespaces
No text mode, and no console is a step back.

Note that most terminal applications still use virtual terminals (`/dev/pty*`), and it is important to provide standard interface here.

Also, terminal makes it easier to debug failing UI, and host headless OS.

You forget that _all_ modern OS transcend the desktop: they support phones, tablets, and headless devices.

miga··on Linux Namespaces Are a Poor Man's Plan 9 Namespaces
You will filter syscalls by filename anyway.

Try `strace|grep open` on any program, and you will be spammed with a number of shared libraries. You need to filter them out anyway.

miga··on Linux Namespaces Are a Poor Man's Plan 9 Namespaces
It was not Unix that become platform for Internet, but Posix.

Linux is not derived from Unix, but supports Unix (Posix) APIs. As does modern MS Windows, and Mac OS X.

This also means that Google could experiment with OSes like Haiku or Fuchsia that support Posix, but are built in a different way.

miga··on Linux Namespaces Are a Poor Man's Plan 9 Namespaces
These are called "special files" in Linux. "Device files" are just a special case.

Both "special" and "device" files are still "files".

miga··on Notice of Intent to Amend the Prescription Drug List: Vitamin D (2020)
Finland supplements milk with cholcalciferol to prevent vitamin D deficiencies.

This lead to public health improvement: the evidence from "The Big Vitamin D Mistake" paper (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5541280/) clearly recommends a dosage of at least 8000IU daily for adults and seniors.

miga··on Notice of Intent to Amend the Prescription Drug List: Vitamin D (2020)
Apparently Bureau of Nutritional Sciences of Food Directorate is responsible for the norms in Canada. I resent the request to update recommendation there and asked whether they reconsidered the mentioned paper.
miga··on Notice of Intent to Amend the Prescription Drug List: Vitamin D (2020)
While vitamin D has extremely no abuse potential, and very rare side effects, the evidence from "The Big Vitamin D Mistake" paper (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5541280/) clearly recommends a dosage of at least 8000IU daily for adults and seniors.

The effects of vitamin D shortage have disproportionate negative effect on population with dark skin tone, but is frequently offset by traditional Inuit diet.

Health Canada should consider recommending 8000IU vitamin D + vitamin K as daily prescriptions to all healthy adults. Fortification of milk with cholecalciferol has been effective in Finnland, so may also be considered.

I sent this to Health Canada email, in case they did not consider the consequences.
