Agreed. But bearded women will likely only be used to bully.
Re:Rejected Emoji Proposals on Saturday February 18, 2023 @04:34PM (#34851338)
The proposal has a section comparing the frequencies for "pregnant-man" and "pregnant-person" with "elephant". It was a criteria back then.

Most (if not all) gender neutral emojis were proposed by the same person.

My issue is with those emojis is that they don't meet a few of their own criteria for a new emoji to be accepted.

Their guideline: https://unicode.org/emoji/proposals.html#selection_factors_i...

For instance, they suggest using "elephant" to evaluate the usage:

I find fascinating that many of those were rejected, but "Pregnant man" and male bride were approved.

Intel released a couple days ago new Xeon-W CPUs with AVX-512.

The wx-24xx uses the same p-cores as alder lake, but with avx-521 enabled. Same for wx-34xx but with raptor lake's p-core.

The entry levels xeon are believed to be identical to Core ix, with the e-cores disabled and avx-512 enabled. The extra I/O and ECC support is done by the chipset.

In summary, they just went to support avx-512 only on xeon w.

This makes sense, since must be hard to schedule between cores with and w/o avx (the e-cores doesn't have avx).

Re:Poline – esoteric color palette generator on Monday February 06, 2023 @09:10AM (#34677470)
Yeah, it is obvious. But word "interpolation" isn't to be found anywhere in the text.

IMO, having something like "color interpolation in HSL Cartesian space" would make it crystal clear what the tool is about. Also, "interpolation" is the keyword I'd use to search for this on Google. So, would likely be an SEO.

Unlike OP, I think it is clever to use words like "enigmatic", "mystical", etc. Not my particular taste, but it is a good branding.

About the transformation. Most libraries can interpolate on CIE's XYZ-D65, but I'm not sure how this would compare with doing operations at Cartesian coordinates of others colorspaces.

The widget from codepen also looks great. You are really good at designing color widgets.

Re:Poline – esoteric color palette generator on Sunday February 05, 2023 @08:34AM (#34664758)
Metamerism is not an issue.

And things such as "viewing condition" and "chromatic adaptation" are part of the color appearance model (CAM). The color spaces assume some reasonable value for those. For instance, a color space used for cinema, assumes dark viewing condition (I don't remember which one).

Also, many TVs and most Apple devices, have sensors to collect environment light, and applies color correction to best represent the color accuracy based on the environment.

But I agree, color science lacks data.

I don't think many people realize that most of the color science theory is based on a color matching experiment done with 1959, without lasers, with a very small biased population (european, males for genetic reason).

Re:Poline – esoteric color palette generator on Sunday February 05, 2023 @08:03AM (#34664597)
This is color interpolation.

There are others js libraries that does the same thing, but they lack a good interactive tools.

But, unlike others tools, this tool exposes the "xyz coordinates". This is exotic.

Re:Morning exposure to deep red light improves declining eyesight on Wednesday February 01, 2023 @10:05PM (#34621524)
There are plenty of evidence that the activation of ipRGC inhibits melatonin production.

My question was about the "ratio of yellow photons to blue photons".

Fun fact: Blue light can stimulates melanogenesis in dark-skinned individual (type III and above) [1], no UV required. This process is mediated by an Opsin, like our vision.

This is a somewhat recent discovery (~2010) and the physiological effects are still largely unknown. Most studies on the subject are concerned about hyperpigmentation and oxidative stress.

"Deep red" leds. They are used to grow cannabis indoor, very easy to find.

Note: Melanopsin is the name of the ipRGC's photopigments.

I've seems studies showing that genetically modified blind mices with ipRGC had circadian cycle. And that just a few photons of blue light is capable of suppress melatonin production in humans.

But I haven't seem anything about supression of melatonin being regulated by the ratio of yellow light and blue light. Could you provide a source?

Despite being a public park, managed by a governmental entity, there is an entrance fee. Likely to restrict the access of poor people, since it doesn't seem to be lacking funds (the data is public).

There is also a rumor that prince Dom Miguel used to hunt chineses for fun nearby the Chinese view [1][2].

It is a beautiful place and worth visiting, thought.

From microarchitecture.pdf

On Alder Lake (pg 172).

On Tiger Lake (pg 167):

> Warm-up period for ZMM vector instructions

> The processor puts the upper parts of the 512 bit vector execution units into a low power mode when they are not used.

> Instructions with 512-bit vectors have a throughput that is approximately 4.5 times slower than normal during an initial warm-up period of approximately 50,000 clock cycles.

I'm not saying you are wrong. I just haven't heard about that.

> It takes literally 1 to 10 microseconds (10,000 nanoseconds) to talk to a GPU over PCIe.

The CPU has an overhead of about ~10us to enable the AVX512 units.

It also dramatically reduces the clock on other cores.

Re:Posits, a New Kind of Number, Improves the Math of AI on Wednesday September 28, 2022 @12:28PM (#33009885)
I've been studying color theory (its harder than you would think) on my spare time; and I did my undergraduate thesis was on posit few years ago. I think using posits may be a good idea to compress the luminosity, but I'm not sure how good it would be for the ab on a Lab-like format.

A format close to the cone fundamentals, like XYZ, could have benefits being encoded in some kind of non-standart posit.

I'll add this into the stack of things I eventually I'll look into.

Re:Posits, a New Kind of Number, Improves the Math of AI on Wednesday September 28, 2022 @12:11PM (#33009650)
Posit always have more precision than a IEEE floating with same number of bits because it has more bits for the mantissa.

Posit would likely enable to better compression with Huffman encoding.

Re:Posits, a New Kind of Number, Improves the Math of AI on Wednesday September 28, 2022 @11:26AM (#33009078)
Something like "compressed floats" would express well the name.
Re:Posits, a New Kind of Number, Improves the Math of AI on Wednesday September 28, 2022 @11:25AM (#33009069)
The posit is a compressed floating point encoding with a flexible data structure with a trade-off of precision (the number of bits after the dot) and magnitude (the absolute value).

It uses more hardware because the posit is decoded into a floating point larger than a equivalent IEEE754 with the same number of bits. So, the logic units needs to be larger.

Re:Why a 224-Year-Old Human Heart Is Touring Brazil on Sunday August 28, 2022 @07:27PM (#32633181)
Yeah. It always all about economy.

Not long after slavery was abolish; loitering became a crime. See "Vagrancy Act 1824".

Re:Why a 224-Year-Old Human Heart Is Touring Brazil on Sunday August 28, 2022 @05:24AM (#32626960)
To be precise. Brazil was the last country from the West to abolish slavery.

Almost 40% of slaves traded over the Atlantic went to Brazil.

Re:Why a 224-Year-Old Human Heart Is Touring Brazil on Sunday August 28, 2022 @04:28AM (#32626732)
I was surprised to find out that Portugal cared.

It is election year in Brazil. The opposition has been portraying this as an example of bad taste of the president (by the way, he has has been insinuating there will be a coup on the independence day -- and it wont be shocking if he try).

Re:Why a 224-Year-Old Human Heart Is Touring Brazil on Sunday August 28, 2022 @04:14AM (#32626669)
Some historical context about Brazilian independence (1822).

In 1807, United Kingdom prohibited slave trade in their colonies and pressed Portugal (that had very close relationship with UK) to do the same.

But Brazilian economy depended on slave labor. And land owners weren't having it.

Dom Pedro I declared the independence to calm down the the elite while keeping the country under Portugal influence -- the newly independent country was a monarchy with an imperator from the Portuguese Royal family.

Thanks to him and his son, Brazil was the last country to abolish slavery.

But hey, at least the country didn't break into many small nations. And avoided wars. So in the end it was good I guess \s.

Changing the sensors would make it very hard to evaluate under the very strict condition they were tested. The system integration would be very hard.

The sensors on JWST have are outdated and do have some issues. For instance, some of the microshutter on NIRSpec are stuck (they knew before launching). The MIRI has some image artifacts due manufacturing techniques.

The sensors were bespoke, even nowadays, we can't get sensors like the on on JSWT off the shelf. There isn't much use case for most of them outside space telescope. But we could do better with today technology.

Thanks for pointing this out. I looked for the domain of fetched resources, and assumed they weren't. It seems they are using, but from their own domain.
