It will probably increase the concentration of water vapor in the atmosphere, which will lead to further warming as water vapor absorbs the heat radiated by Earth.

random_ind_dude··on XCheck at Meta: Why it exists and how it works
You know, someone not liking the current Indian government doesn't mean they hate India. To those in the US, Meta meddling in politics and turning a blind eye to those who used the platform to peddle misinformation isn't news.

Ankhi Das, a top Facebook India executive left the company in 2020 over allegations by the WSJ that the company favoured the ruling party when it came to removing posts that violated its hate-speech rules. So putting business above integrity is nothing new for Facebook in India either.

random_ind_dude··on Tell HN: Razorpay a YC company shared donor data under a Section 91 order
A bit more context: The Gyanvapi mosque is older than the United States and the current controversy has been stirred up by Hindu nationalists targeting India's Muslim minority.

Nupur Sharma's statements created an international controversy for India with several Gulf countries demanding a public apology from India.

Zubair was arrested within days of a complaint being raised on a tweet he made in 2018, while Nupur Sharma hasn't been arrested yet, even after causing an international incident.

IMO, Razorpay would have been forced to give up the data, Section 91 or not, since the current government doesn't really care about due process.

The link below gives more details about the tweet that led to Zubair's arrest.

https://www.business-standard.com/article/current-affairs/tw...

Excerpts from the above article:

> According to the FIR, Zubair had used a screengrab of an old Hindi movie which showed an image of a hotel, with its board reading 'Hanuman hotel' instead of 'Honeymoon hotel'.

> In his tweet, Zubair had written: "BEFORE 2014: Honeymoon Hotel. After 2014: Hanuman Hotel".

> The complainant -- Twitter user @balajikijaiin, tagging the Delhi Police had written: "Linking our God Hanuman Ji with Honeymoon is a direct insult of Hindus because he is a brahmchari. Kindly take action against this."

> Noting the complaint, the police in the FIR said that the words and pictures used by Zubair in the tweet against a particular community were highly provocative and more than sufficient to incite feelings of hatred among people which can be detrimental for maintenance of public tranquility in the society.

random_ind_dude··on Daytime napping and Alzheimer's dementia: A potential bidirectional relationship
To me the study is interesting in that it found an association between the duration of daytime napping and the progression of dementia and that those two feed into each other. While it's true that there have been studies that linked poor sleep to cognitive decline, the study being discussed here, in my opinion, offers a new insight that should not be dismissed out of hand.
random_ind_dude··on Daytime napping and Alzheimer's dementia: A potential bidirectional relationship
What makes you think that the scientists didn't consider the possibility that poor sleep at night was the actual causative factor driving the progression of mild cognitive impairment (MCI) and Alzheimer's dementia?

From the paper:

>Nighttime sleep disturbances are known risk factors for developing cognitive impairment or dementia. We found that the association between excessive daytime napping and incident Alzheimer's dementia remained with similar effect sizes after adjustment of covariates for nighttime sleep quantity and quality including sleep duration, sleep fragmentation, and WASO, implying a role of daytime napping independent from changes in these nighttime sleep-related characteristics. We further note that we did not observe direct associations between these nighttime sleep measures and incident Alzheimer's dementia. Therefore, it is unlikely that the increased duration and frequency of daytime napping were simply to compensate nighttime sleep loss; there might be other underlying disorders that affect, for example, the wake-promoting network that leads to lengthened sleep during both daytime and nighttime.

A right-wing website that's extremely sympathetic to the current right-wing government in India is how you rebut V-Dem's classification of India as an electoral autocracy.

random_ind_dude··on Prime Video Uses WebAssembly
Well, X-Ray is a feature in the Prime app that I like and use quite often and is very snappy. Since it's part of the UI overlay, I think it's handled by the WASM module (probably with local caching) and not by the dedicated video-decoding hardware in the TV.

I agree that the browsing UI can sometimes take an extra second or two to refresh which I don't find to be a dealbreaker since it's the video/audio playback that I care about the most.

random_ind_dude··on Prime Video Uses WebAssembly
I have an LG UHD TV model from 2020 running webOS and I haven't noticed any performance issues either with Prime Video, UHD, HDR or otherwise. I use Bluetooth speakers/earphones for audio. The sound is almost perfectly synced with the video in Prime while there is a noticeably annoying delay in the Netflix app on the same TV.

random_ind_dude··on Google Docs will now use canvas based rendering
You are correct. I meant Google Sheets instead of Google Docs. I thought I'd tackle the word processor part once I got the spreadsheet to a usable state. I do think Google Docs suite is used as an umbrella term to refer to all the Google collaboration tools like Docs, Sheets, Forms etc.
random_ind_dude··on Google Docs will now use canvas based rendering
The name Writely reminds me of a side project I worked on around 2010. I was not satisfied with the performance of Google Docs and its competitors at the time like EditGrid and thought (naively, as it turned out) I'd be able to develop a faster alternative.

I had no idea what I was doing and thinking that using JavaScript to manipulate the DOM was going to be slow, I chose ActionScript and Flash as the language and runtime to develop the project in. I wrote a client-side expression parser and formula engine, and managed to develop a functioning spreadsheet UI with resizable rows and columns, copy and paste with Excel-like animations, cell references etc.

The problem that I ran into was text-rendering when there was a lot of text on the screen. The application would consume a lot of memory and the page would slow down to a crawl when scrolling. I couldn't really find a way to speed up the performance and stopped working on the application after some time. That's when I realized the incredible amount of work that went into Google Docs and other web-based spreadsheets. :)

random_ind_dude··on Statement on New York Times Article
You say you have found an ally in someone who is known for his controversial take on intelligence and heritability and who maintains that it is this inherited difference in intelligence that is responsible for social division within the US. You call his ideas on class and culture sophisticated. Then you say that you agree with him only on a certain specific claim about teaching truckers to code. (You = Scott Alexander)

Who is being intellectually dishonest here? NYT or Scott Alexander?

random_ind_dude··on A first look at Unreal Engine 5
It was possible to use Quixel assets in UE4 as well.

https://www.youtube.com/watch?v=9fC20NWhx4s

The assets used in the UE5 demo are available in Quixel's website.

https://quixel.com/megascans/collections?category=environmen...

The 8K cinematic assets that Epic used in the demo are between 1 and 2MB in size. So I suspect it's more to do with PS5's SSD which has a bandwidth of more than 5GB/s and 16GB of GDDR6 RAM, which allows more textures to be streamed from the hard drive and held in the RAM.

PS5's GPU supports raytracing, which Epic said they didn't use in the demo. So the dynamic lighting must be something new they've developed for UE5.

random_ind_dude··on A first look at Unreal Engine 5
The graphics look good because of two things: Quixel and global illumination. Quixel is Swedish company that Epic acquired in 2019. Quixel does high-resolution scans of actual physical objects(photogrammetry) and makes them available as textures in Unreal Engine. The sheer rock faces that you see in the demo are Quixel megascans of actual rocks.

The other thing that makes the graphics look impressive is global illumination, which provides real time dynamic lighting of the environment, instead of baked in (pre-rendered) lighting. The demo seems to only have a single light source - sunlight in the cave, light from the crystal looking thing in her hand while inside the room. I am not sure how well it look like in actual games when there are multiple light sources.

The rest of the stuff doesn't look too different from current gen games.

If, at some point in the future, scientists figure out a way to coax normal cells to become totipotent, will you consider amputation as murder?

random_ind_dude··on Who are the Chinese tech companies that just bought Opera?
It doesn't work for me either. The fault lies with HN. I think the reason text reflow doesn't work on HN is that HN styles its content using old-fashioned HTML tables instead of DIVs.
random_ind_dude··on Who are the Chinese tech companies that just bought Opera?
Dolphin does have text reflow. There is an option that says 'Auto-fit pages' in advanced settings, which is the same thing as text reflow. That option is the only reason I'm using Dolphin as my mobile browser. I used to use Opera before, but after they switched to Blink, an annoying bug that reloads a tab when it is selected, became a deal breaker for me.
random_ind_dude··on Only 3 northern white rhinos left on Earth
>India itself is a big importer of horns and I think much bigger then China

That's not true at all. In fact India has two-thirds of the world's great one-horned rhino population in the Kaziranga National Park.

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

There are armed guards protecting the rhinos and they've even shot and killed poachers, though poaching still happens due to demand from Southeast Asia.

As per the article below, Vietnam is the country that is driving the current demand for rhino horns.

random_ind_dude··on On Being Smart (2009) [pdf]
Can you completely discount the part played by one's innate ability, though? I have been able to sing in tune and play percussion instruments (mainly the tabla) from a very young age, though I am no prodigy. Sadly, I was never motivated enough to put in the effort to become better at music and am still an amateur.

I think I'd have had an (initial) advantage over someone who absolutely sucks at music and is learning to sing or play a percussion instrument.

I feel the same thing when I look at people who are much smarter than me when it comes to intelligence.

random_ind_dude··on India's Forgotten Stepwells
On reading galtwho's comment again, I feel you are right. I thought he/she was repeating the post-hoc reasoning that is common in India, where people would take a ritual and assert that ancient Indians knew about scientific ideas that are common knowledge today and based the ritual on those ideas.
random_ind_dude··on India's Forgotten Stepwells
I can't find anything on the Internet to support the theory that greeting by way of Namaste was practiced for hygiene reasons. Do you have any citations for that?
random_ind_dude··on Illustrated Book on Indian Mars Orbiter Mission
I find it interesting that sending a probe more than 200 million kilometers to another planet is a lot easier than launching multi-ton payloads into the geosynchronous orbit.

I am referring to the fact that India still relies on the ESA to launch its communication satellites.

random_ind_dude··on Quake on an oscilloscope
An oscilloscope is a cathode ray tube that has an electron beam that can be moved around by applying varying voltages to its inputs. In this case it works as an XY plotter, i.e., you specify the X co-ordinate by the value of the voltage on one input and the Y co-ordinate by the value of the voltage on the other input.

You can display lines on the oscilloscope screen by giving a specially generated two channel audio as its input; one channel works as the X co-ordinate and the other one as the Y co-ordinate.

The game (Darkplaces which is a source port of Quake) renders a scene that has the lines to be drawn (triangles, in fact) on screen. The output of the game, i.e., the lines to be drawn on screen are sent to an audio synthesizer process(PortAudio). This process uses a sound card to create the audio. The output of the sound card is connected to the inputs of the oscilloscope which draws the lines on its screen.

So it's not the sound in the game that is producing the actual image. The output of the game is converted to an audio signal which when given as input to the oscilloscope creates the actual image.

random_ind_dude··on ChangeTip must die
That explains what I saw in a few Reddit threads where a user was tipping everyone for no reason at all! Some of the users that got tipped got angry and some got curious about Bitcoin.
