> I'd love to see pledge/unveil on (upstream) Linux - but I'm not holding my breath

There is Landlock now, I believe it would be possible to implement unveil and pledge on top of that.



... And looks like cosmopolitan libc wraps landlock for unveil, in addition to implement pledge.


One of HN's favorite hackers has done that: https://justine.lol/pledge/

There was a discussion here about it a few years ago: https://qht.co/item?id=32096801

Interesting choice of word


She's excellent and her stuff has made it to the front page many times. I love seeing her work come up and I imagine many others here feel the same way.


If you're someone who can separate the work from the author, sure. She's a very intelligent person. Many of us can't.


Fair enough. I didn't know what was supposed to be objectionable about her personally until your last comment made me do some Googling. Bleh.

To be honest, I feel like I still don't really know much about who she really is or what real political work she's doing recently, if any. And I kinda don't wanna know anyway; I don't wanna play political blacklist enforcer.

But I understand your reaction now. :-\


There are a number of licenses that are named MIT that are all similar, but not identical.

The "Expat" here is the MIT license variant. It is referring to the Expat XML parsing library that first used this license.

Usually when projects these days use an MIT license this is the version they use.


The letter also said it was conditional on the combined entity maintaining investment-grade credit rating, which seems unlikely if the combined entity was saddled with $20B in debt.


> It works great as long as you squint just a bit, ignoring that it generally calls for long,lat and is designed with the assumption of a world CRS.

I thought the spec allowed you to specify the CRS, but I just checked the RFC and they removed that from the 2016 specification and WGS84 is specified. It does allow for alternative CRS with prior arrangement, but like you said that does require a lot of care.


Yes, they deprecated the CRS field and the current state of geojson handling libraries is pretty messy as a result since geojson does not have versioning!

If you have old geojson in a different projection, will your library respect the crs field or will it simply misinterpret your data?

Wondering if anyone could shed light on the decision to remove it as a standard when projection seems to be a critical part of GIS.


Coordinate systems and projections are one of those deeply complicated truths that makes such a headache in GIS. I still shudder at all the pain in school and at previous jobs dealing with inconsistent datasets.

It seems like they decided to just opt out of trying (see the yellow box in section 4): https://stevage.github.io/geojson-spec/#section-4

I think they should have completely backed off from touching on projections and datums in the format altogether. Ie. Something like, “coordinates are 2 or 3 tuples where the values in order correspond with easting/long and northing/lat and elevation/altitude. See metadata for agreed upon units and CRS/projection semantics. It is strongly encouraged to standardize on WGS84 when encoding data with an earth-resolvable datum.”

Because GeoJSON otherwise works fine for indoor spaces, video game spaces, fictional lands, other celestial bodies, etc. You just have to educate on the idea that there’s more to data compatibility than it being GeoJSON.


Yup, technically speaking if the coordinates aren't in WGS84, it isn't GeoJSON


The hot dogs are 1/4 lb, with the bun it's probably 500-600 calories.


Yes, they have a number of domain names, archive.is and archive.today are the most well known ones.


It's almost a certainty that you can't copyright code that was generated entirely by an AI.

Copyright requires some amount of human originality. You could copyright the prompt, and if you modify the generated code you can claim copyright on your modifications.

The closest applicable case would be the monkey selfie.

It's almost certain that you're wrong. It's like saying I can't copyright a song if my modular synthesizer generated it. Why would you think this?


You're using too much! Its commonly used to improve meat texture, especially in Chinese cuisine. It's called "velveting".


you're thinking of corn starch


Both are used, for different reasons, but it's a pretty loose term. Can also use enzymes or other alkaline things. With or without a marinade. Pass through oil or water, or just stir fry with a little extra oil.


The thermal gradient in space is meaningless because there is hardly any matter to dump the energy into. This means you are entirely reliant on thermal radiation. If you look at the numbers given by Stefan-Boltzmann law you'd see that means to radiate a significant amount of energy you need a combination of a lot of surface area and high temperatures.

This means you need some sort of heat pump. For a practical example you can look at the ISS, which has what they call the "External Active Thermal Control System" (EATCS), it's a complicated system and it provides 70kW of heat rejection. A datacenter in space would need to massively scale up such a system in order to cool itself.


The ISS comparison is a bit of a category mismatch. The EATCS is complex because it’s a life-support system that must keep humans at exactly 22C (295K) while managing ammonia loops in a manned environment.

Computers aren't humans. High-performance silicon can comfortably operate at a junction temperature of 80C to 90C (approx. 360K). Because of that T^4 relationship, a radiator at 85C rejects nearly double the heat per square meter than a radiator at 20C, unless I miss something.

So this makes it a bit more nuanced.


Is there a credible way to cool a space-based data center on that scale?


There's not even a credible way to transfer meaningful amounts of data to and from a deep-space based data center.

What good is compute if you can't interface with it? This is where we are now: https://en.wikipedia.org/wiki/Deep_Space_Optical_Communicati...

SpaceX may be leading in short-range (few hundred km) space-to-space data transfer but there is a long way to go for terabit/s deep-space links.
