sqrt_1··on Brood War Bench
I thought that it was videos of the replays on the site. Was very impressed that it was a replay playing that you can scroll around in and select units.
sqrt_1··on Gaussian Point Splatting
There was this FPS demo recently https://playcanv.as/p/qxGSuzYq/

People have also converted some small sections of Unreal 5 demos into splats https://superspl.at/scene/692c4f91

Or perhaps use a real world scan - it was suggested this one would make an ideal setting for zombies https://superspl.at/scene/6359774f

sqrt_1··on US will ban Wall Street investors from buying single-family homes
Current government has explicitly said that they will not lower hose prices:

"We're not trying to bring down house prices," Housing Minister Clare O'Neil declared on ABC's youth radio station triple j.

"That may be the view of young people, [but] it's not the view of our government."

John Carmack likes how Grok will tell him he is wrong.

sqrt_1··on Debunking the Myths of the HBO Chernobyl series (2023)
It really annoys me when fiction is based on real events, takes a lot of liberty with the source material that it enters into the public consciousness.

The classic case is the "The Life and Voyages of Christopher Columbus" where it was claimed he was aiming to prove the Earth was not flat. My personal peeve is movies like "The Imitation Game".

sqrt_1··on My dad could still be alive, but he's not
I think it is mostly just a problem with Victoria - and they are are hardly conservative. Hospitals and ambulance service is a state issue and other states fair much better.
sqrt_1··on I hate screenshots of text
Windows built-in snipping tool (shortcut Win + Shift + S) also has a text actions button to extract text.

sqrt_1··on Tesla market share in US drops to lowest since 2017
Looking at your link, it seems to be US only stats?

Best selling in 2024 world wide was Model Y even including trucks? https://www.visualcapitalist.com/ranked-the-worlds-best-sell...

sqrt_1··on Writing into Uninitialized Buffers in Rust
This is well outside my expertise, but some discussion happened at the time https://www.reddit.com/r/programming/comments/56xxmb/the_str...

Some people suggest that maybe Facebook runs with MAP_UNINITIALIZED

sqrt_1··on Writing into Uninitialized Buffers in Rust
I don't believe they are allocating 128 bytes, or accessing out of bounds memory.

He explicitly states 128byte filename allocates 129 bytes. https://www.youtube.com/watch?v=kPR8h4-qZdk&t=1417s

sqrt_1··on Writing into Uninitialized Buffers in Rust
It was from C++con 2016 - Facebook take on small strings https://www.youtube.com/watch?v=kPR8h4-qZdk&t=1343s I believe it is about a page that was conditionally returned to the kernel.
sqrt_1··on Writing into Uninitialized Buffers in Rust
Related to unspecified vs undefined. I recall some C code was trying to be tricky and read from just allocated memory. Something like:

int* ptr = malloc(size); if(ptr[offset] == 0) { }

The code was assuming that the value in an allocated buffer did not change.

However, it was pointed out in review that it could change with these steps:

1) The malloc allocates from a new memory page. This page is often not mapped to a physical page until written to.

2) The reads just return the default (often 0 value) as the page is not mapped.

3) Another allocation is made that is written to the same page. This maps the page to physical memory which then changes the value of the original allocation.

sqrt_1··on Making a smart bike dumb so it works again
I would settle for something like - "any network functionality in consumer devices must be open sourced and user modifiable"

It is probably too high a bar for most manufacturers, so they will not likely include such functionality.

AoE2 is coming out on PS5 this year.
sqrt_1··on Tesla sales drop 35% in San Diego County
Didn't Tesla's top selling car (Model Y) get a refresh last month? Potentially a lot of buyers waiting to get the new model.

sqrt_1··on Association between prenatal exposure to plastics and autism in boys
Higher levels of bisphenol A (BPA), a plastic commonly used in food packaging, were detected in urine samples taken from women pregnant with boys later found to have autism. Florey researchers identified the biological molecular mechanism underlying this association.
sqrt_1··on Ask HN: Why isn't it easy to compile dlls inline?
And the other reason for dlls for common system libraries, security. If a security bug is found in a dll that is shared amongst a lot of programs, that can be updated without having to recompile all the programs.
sqrt_1··on Ask HN: Why isn't it easy to compile dlls inline?
If you are thinking about the C runtime on Windows, you can statically link those dlls into your program via compile time options.

There are valid reasons for dlls however. The main one being symbol name collision.

For example, you can use a dll that links to version 1 of a library, while using version 2 of the library yourself without having any name collisions.

Many years ago when I did Linux development this was a main gripe of using .so files - imported names could clash with the same global names in your program and you get random runtime behaviour.

sqrt_1··on E621, Pornhub, and others block North Carolina residents
I don't think a town in Tennessee recently outlawed homosexuality in public,

They just added: "No person shall knowingly while in a public space engage in indecent behavior, display, distribute, or broadcast indecent material, conduct indecent events, or facilitate any of the foregoing prohibited acts."

Problem was that the referenced indecent statue definition included homosexuality, which was then removed from the definition even before it blew up on social media

sqrt_1··on Replace peer review with “peer replication” (2021)
FYI there is a at least one science journal that only publishes reproduced research:

Organic Syntheses "A unique feature of the review process is that all of the data and experiments reported in an article must be successfully repeated in the laboratory of a member of the editorial board as a check for reproducibility prior to publication"

sqrt_1··on We built voice modulation to mask gender in technical interviews (2016)
This reminds me of when the Australian government did blind recruitment.

"Blind recruitment means recruiters cannot tell the gender of candidates because those details are removed from applications."

"The trial found assigning a male name to a candidate made them 3.2 per cent less likely to get a job interview.

Adding a woman's name to a CV made the candidate 2.9 per cent more likely to get a foot in the door."
