arthur2e5··on ReactOS Shown Running on Valve's Steam Deck
Marveling at this sentence structure.

> While not suitable for any serious gaming yet with the binary compatibility of ReactOS for modern Windows games still being rather limited especially among Windows device driver support, in early experimental form this open-source OS is up and running on the Steam Deck!

arthur2e5··on Phenylephrine for colds and allergies don’t work, FDA panel says
Chronic nose problems really do require something else. During bad months I start with a regular antihistamine and then to escalate to ketotifen (somehow OTC in China), and if that doesn't work, saltwater rinse (look, I'm lazy). Pseudoephdrine goes after salt water -- I just don't like to go to a physical pharmacy, so I want my stock to last as long as it can.

For some reason steroid spray never seems to work on me. I spray it, it drips out, nothing happens.

arthur2e5··on Oxford study proves heat pumps triumph over fossil fuels in the cold
Comment confused me a little bit (won't heat pump heat be reused too?), until I realized that you were factoring in gas-to-electricity efficiency. That makes sense.
arthur2e5··on Phenylephrine for colds and allergies don’t work, FDA panel says
The issue with phenylephrine is that it does not help the symptom. Pseudoephedrine does not deal with the underlying immune reactions, but it does constrict your nose blood vessels enough to stop the mucosa from stuffing your nose holes.

Having your nose unclogged is very useful on its own, considering otherwise you'd be forced into mouth-breathing, which would lead to more discomfort and potentially worse outcomes like sleep apnea.

arthur2e5··on Apple should re-release Safari for Windows
Funny enough, that might be exactly why web devs want Safari on Windows, optimally with the whole Apple media stack like iTunes is already shipping: to know what their website would do on a Mac without having one.

(Media stack? Yes, I am salty about Opus Ogg support.)

arthur2e5··on Are any words the same in all languages?
Japanese used to do this thing too -- back then Kanji was still the proper scholarly thing to use and scholars were the main contact to Western knowledge. In fact, a good number of Chinese words for Western concepts came from Japanese translations. 社会 society, 经济学 economy, 自由 liberty all came from Japanese translations.

arthur2e5··on China's ancient water pipe networks show no evidence of a centralized authority
The full title is "China's ancient water pipe networks show they were a communal effort with no evidence of a centralized state authority". Trimming the title down really buries the lede. Try "China's ancient water pipe networks were a communal effort" if you want to fit the character limit.
arthur2e5··on Human embryo models grown from stem cells
Nice, the Nature news article links to the biorxiv version of three papers. The one linked by TFA is Oldak, https://doi.org/10.1101/2023.06.14.544922.
arthur2e5··on Human embryo models grown from stem cells
Biologists have been messing with the console since a long time ago. They figured out what each gene does in large part by turning them off one by one, or occasionally making them run more than they should (overexpression). Even before they had the whole genome, they used random mutagenesis and slowly analyzed what got broken by breeding experiments. With enough data you can even locate it on a chromosome relative to known genes by linkage maps.

The most fun stuff to mess with is of course parts that controls how other stuff works. Figuring out what makes stem cells want to grow into shapes will lead us to more of these control switches.

arthur2e5··on Satlas: Open Geospatial Data Generated by AI
Does satlas currently use any channels other than Sentinel's visible RGB? I imagine that those near IR bands can be very useful for plant-related tasks and (with a long stretch) potentially help with object discrimination by adding an extra band.
arthur2e5··on Satlas: Open Geospatial Data Generated by AI
The super-res is surprisingly usable for making sense of land use changes. With OpenStreetMap editing, one common challenge is that out of the usable (license-wise) imagery, the high-defs ones are old and the new ones from Sentinel are low-def. A lot of switching, squinting, and gusssing is required to understand of what's going on, even when most of the work is as basic as trying to spot this old road in the blurry new image. This super-res seems to do that well enough. It doesn't have enough information to guess the exact shape of buildings and that's okay.

They also do some object recognition, which is useful if you're an electric infrastructure nut. It spotted some solar fields in Shanghai which I've never heard of before -- a look at the same coordinates (30.753, 121.392) on Google sure shows the expected blue.

arthur2e5··on A currently maintained fork of SSHFS
SFTP is a major step up from FTP, but there's a lot of unrealized potential on the server side, so you can't just work on better clients. Both OpenSSH and the GNU lsh server only offer an old version of the protocol -- v2, I think. That oldness is intentional: https://marc.info/?l=openssh-unix-dev&m=168488976013498&w=2
arthur2e5··on Climate Change Tracker
Graphs of what? CO2 concentration when the initial was never 0, except for when Earth had no atmosphere? Average temperature when a 0 would be an ice age? The "change" graphs start from 0, and that's what matters.

Any hypothetical sequestration into a fuel (as in the parent parent comment) would also require a power source, so the question goes back to low-carbon power!

arthur2e5··on Evergrande shares plunge as much as 87% as trading resumes after 17 months
Young people in Shanghai, Beijing, Shenzhen, and Xiamen/Amoy haven't had the means for a flat since... at least 6 years ago, when the per-square-meter price broke CNY 50 K. It's been understood as "maybe my parents have some savings from the 拆迁 demolition money for the down payment" sort of deal since then.

Smaller cities are more possible though.

* * *

Tangential: a good part of everyone's income in those big cities goes into rent and mortage, from the average worker to the restaurants and shops downstairs. It's always been screwed.

> Also, there's a reason Y has survived since 1900, and it's not because it's an arbitrary decision.

1931. And Y is known to be problematic since Judd (1951) and Vos (1978), with the latest approach being the Stockman & Sharpe 2005 "fundamental" redefinition. This error has real bearing on how narrow-spectrum display works.[1]

> I assume it's a reference to the shape of Oklab's L... not close

The "a little skewed" refers to the shape of the L (or CAM "J") axis projected into the 3D XYZ space, not how the values are scaled in 1D (which I have addressed separately as L_r). They will not perfectly match the Y axis and appear bent, even skewed, because they don't just mathematically depend on Y. But they will be quite close and score a good (> 0.90, I guess) correlation coefficient over a set of color samples because they are trying to model the same aspect of human vision. That is still good correlation, and given the limited nature of gamuts you'd still be able to derive some sort of "this much difference means at least this much ratio".

arthur2e5··on Photogrammetry on commercial flights (2021)
It's mostly the direction: you don't get a lot of vertical acceleration on land except on a bumpy road or a amusement part. Slight loss of gravity takes some getting used to.
arthur2e5··on Photogrammetry on commercial flights (2021)
ODM is a way to preprocess data before sending it to OAM, but it does not itself provide a sharing platform.

One barrier for OAM seems to be that it requires the image to be already orthorectified. To be more like Mapillary you'd need a service that takes georefed pictures and does its own processing.

In the case of airplane window photos where georef is not going to be good enough, you might need existing photos to correlate with -- ADS-B track combined with time can help provide a starting guess, but not much else.

arthur2e5··on Buffer Overflows in Notepad++
You are right: NTFS exclusively runs on UCS-2, now "UTF-16 without validation". Back in the 1980s "Unicode" referred to a way to represent the ISO standard "Universal Character Set", i.e. UCS-2, instead of being synonymous to the entire character set like today. The wisdom of i18n back then was to use "Unicode" text encoding because it covered the known universe of writing. Qt made a similar choice.
arthur2e5··on Buffer Overflows in Notepad++
It's hard to beat an extensible project maintained by Microsoft with a Windows C++ project written by one guy.

(I personally ditched n++ because the shell highlighting false-positives errors, and syntax errors are especially ugly in the default scheme. And it wasn't on GitHub back then, so complaining would be a chore.)

> Oklab L is not L: The problem for engineers and designers: no relation to LAB L*/XYZ Y

That should not be considered a bug by itself. CAM16-UCS lightness J also does not depend only on XYZ Y.

> no correlation to WCAG

Y does not necessarily have to be the standard used by WCAG (see CAM argument). And a stick that's a little skewed is still very well correlated with an upright stick, statistically speaking.

> The problem on the designers end: it's not a linear ramp in dark to light visually.

Now that is the actual issue which has nothing to do with which variables L depends on. The L_r (lightness with reference) derived from L is designed to deal with that: https://bottosson.github.io/posts/colorpicker/

It's mentioned in the article as WCAG 3, APCA algorithm. The most important improvement in APCA is an exponent term.
arthur2e5··on Linux 6.5 Last Minute Fixes a Performance Regression, 34% Drop in a Benchmark
> camellia_aesni_avx_x86_64

An interesting point here is that AES-NI can be used to accelerate a host of things other than AES. In this case, it's because the S-box can take advantage of the AES S-Box (SubBytes) instruction because of affine isomorphism or something: https://github.com/jkivilin/camellia-simd-aesni; https://kernel.googlesource.com/pub/scm/linux/kernel/git/sha....

Similar acceleration has been done with SM4, the Chinese analogue of AES. https://github.com/mjosaarinen/sm4ni

Note that recent low birthrate i.e. (2) does not immediately map to shrinking real estate demands: young people born 20-30 years ago are still moving to cities, looking for a job, and a place to sleep in, hopefully with not-too-long commutes. There will still be a bunch of young couples trying to get a home and being ruined by unfinished construction like you've mentioned.
arthur2e5··on XHTML Club - Extreme HyperText Movement for Luddites
Cool(?) to see XHTML (the XML serialization) becoming dead enough for people to use this name in some other HTML-related thing.
arthur2e5··on LibreOffice 24.2 Will Succeed LibreOffice 7.6
LibreOffice has pretty cool support for working with PDFs in general. (Tangential) There's a "hybrid PDF" export option in LibreOffice that lets you embed ODF metadata into the PDF file. When you open the exported file in LibreOffice again you get everything back -- dynamic fields, header/footers, custom style sets, etc.
arthur2e5··on Wine 8.0.2 Released
https://www.winehq.org/news/ is a lot more helpful. It tells you two things:

* 8.0.2 is just a patch release; the 8.x branch has been running forward for 8 months to reach 8.14

* the real 8.0 feature list is in https://www.winehq.org/news/2022120901, the 8.0-rc1 article from Nov 2022

arthur2e5··on How Surround Sound for Headphones Works (2014)
(Lack of near field is related to the lack of physical distance units in OpenAL, according to the author in the two issues related to this feature. Games have always used whatever they wanted to use; if OpenAL-soft, a plug-and-play replacement library, added near-field, you might get Zombie ASMR breathing down your neck in L4D2 or something similarly unexpected. The same reason was given for not doing headtracking.)
