hortense··on AlphaFold 2 is here: what’s behind the structure prediction miracle
Python is bad, but bash is worse as soon as you need any kind of logic.

> explaining ppl how to use Python subprocess Module Launch different apps, capture their output

There's no shame in using `os.system`.

hortense··on France fines Google €500M over copyright row
Can fines given in a country be deducted from profit in an other country?
hortense··on Show HN: Streaming Raspberry Pi games to a Game Boy Advance
Very cool. You are pretty close to being able to play Stadia on GBA :-)
hortense··on What DeepMind’s AlphaFold 2 really achieved (2020)
One thing that DeepMind demonstrated was that sometimes one well funded team is much better than 50 poorly funded teams.
hortense··on 150 people fatally shot in more than 400 shootings over the 4th of July weekend
We have no point of comparison. Is this more than usual?
hortense··on Bring back menus, QR codes are terrible
One thing that is fantastic about digital menus is that you can search in them.
hortense··on Path Tracing Quake in Blender
To take advantage of a 1000 Hz monitor, you'd need to render 1000 different images per seconds!

And if you can renderer 1000 images per seconds, then generating motion blur that work on a 100 fps monitor is as simple as displaying an average of 10 frames.

The various motion blur techniques allow simulating higher frame rate without paying the full cost of rendering all the extra frames.

hortense··on A few thoughts on Fuchsia security
That's accurate:

hortense··on Apps supporting account creation must also offer account deletion
A related question about this: if an account was flagged for something (e.g. the account was shadow banned), is it OK by GRPD standards to:

1/ not tell the user this info.

2/ keep track of the fact this account was flagged after the account was deleted, for instance by keeping a hash of the email address of the accounts that were flagged?

hortense··on Google is officially releasing Fuchsia OS, starting with a first-gen Nest Hub
They have an OS running on a consumer device that connects to the wifi where you can play media, browse the web, and run flutter apps, so it seems like they already put the time and effort.

It even self-updates, so in some sense it's already ahead of the standard linux distributions!

hortense··on France is testing free public transport
I wonder what is the cost of accelerating 60kg to 40km/h every 2 minutes for a day.
hortense··on Android's new Bluetooth stack rewrite (Gabeldorsh) is written with Rust
That would be Google's second (at least!) bluetooth stack in Rust, the first one being in Fuchsia.

hortense··on Running unmodified Linux programs on Fuchsia
One of the goal of microkernels is to get rid of a whole class of security issues. In some cases it may trade performance for that. In some cases you can get better performances, but you have to rewrite your software to take into account the microkernel.

Regarding Cosmopolitan, one issue is that different executables can't talk to each others efficiently because they are in separate unikernels. If they are running in the same unikernel then you have essentially zero security, unless your unikernel is actually running another kernel!

In other words, unikernels aren't great for consumer devices.

hortense··on Expanding Fuchsia's open source model
Anyone else bothered by the black banner saying "Google is committed to advancing racial equity for Black communities" in technical documentation (https://fuchsia.dev/fuchsia-src/contribute/roadmap) ?

This is simply an advertisement for Google, and just like any other advertisement it has nothing to do in technical documentation, especially in a project where they want other companies to contribute.

hortense··on Apple Ending "Fortnite Save the World" Updates for Mac
They can't, and that's the whole point. The security comes from the sandbox, not from the review process.
hortense··on Tim Sweeney on Apple and Google
Reading the comments it seems that very few people understand this, which seems incredible to me.
hortense··on Where Am I? NYTimes or Google?
Amp was a reaction to Apple News and Facebook News: using those applications to read the news was a much better experience than using the web. Why? Mainly for two reasons:

1/ Apple and Facebook were hosting all the content.

2/ The content did not come with megabytes of JS and other unnecessary crap.

Amp is an attempt at saving the web, and Google is interested in that for the reason that you gave: they make their money from the web.

hortense··on Apple Music on Android requires its own payment details to avoid Google 30% cut
Google Music is 30% more expensive when purchased via iOS. If that seems insane, it's because it is.
hortense··on DeepMind introduces ‘EATS’: adversarial, end-to-end approach to text-to-speech
It's crazy that Google is doing all that research and giving it for free to all their competitors.
hortense··on Folly – Faceboook’s open source C++ library
"folly requires gcc" That's surprising to me. Clang and the associated tools are so useful I would have expected all tech companies to have migrated to it.
hortense··on Tiny electric car looks like a washing machine and costs just $6,600
This is an electric car with an USB charge slot. Your phone is not going to die before your car.
hortense··on BrachioGraph – a cheap, simple pen plotter
You can improve the precision by using visual feedback, but there are movements that are impossible to do if you don't have precise enough motors.
hortense··on Rejected from YC (Again)
A form builder can evolve into an app builder.
hortense··on Improving Form Controls in Microsoft Edge and Chromium
Are these changes only for Windows?
hortense··on Global Illumination in WebGL
I feel like you don't know what you are talking about. Do you know what a cubemap is, how to generate one, and how to use it to render reflections?
hortense··on Asciicker – an online 3D game demo rendering to ASCII text
You can see the progression by starting with http://asciicker.com/x1/

Very nice.

hortense··on A second whistleblower working at Google comes forward to warn of search bias
> What would cause someone to just leave that and turn against the company?

He didn't leave, he got fired because he was stupid and got caught.

hortense··on Fuchsia OS Introduction
It will increase stability in a very important way because they apparently want stability of drivers, which Linux does not offer.
hortense··on We Need Chrome No More
> Among the tech crowd, probably. For the remaining 99.99% of users, absolutely not.

Guess who sets up the computers for the remaining 99.99%? If you seduce the tech crowd, you also get the other users.

hortense··on Entity–component–system (ECS) back and forth
I've been wondering for a long time about how ECS can be cache friendly.

If you look at Overwatch's ECS ( https://youtu.be/W3aieHjyNvw?t=326 ), there are many systems that can read from 10+ different components. For every entity in this system, at least 10 reads with no locality whatsoever are done. That seems crazy slow to me.
