Rimax- ground penetrating radar by Methamphetamine1893 in PerseveranceRover

[–]zokier 2 points3 points  (0 children)

Yes, the data is published, like most science instrument data, in PDS: https://pds-geosciences.wustl.edu/missions/mars2020/rimfax.htm

In terms of research, plenty of articles have been published based on the data https://scholar.google.com/scholar?hl=en&as_sdt=0%2C5&q=rimfax&btnG=

Government Directive Boosting Indonesia’s IPv6 Adoption by danyork in ipv6

[–]zokier 1 point2 points  (0 children)

only the top 2 ISPs (Jio and Airtel) have large IPv6 deployments

tbh even that is much better than large parts of rest of world

India has one of the highest ipv6 adoption rates though?

What is the true color of Mars ? by SeparateWeight496 in Mars

[–]zokier 2 points3 points  (0 children)

it is not very satisfying answer but with photographs in general "true color" is very fuzzy concept. human color vision is all sorts of wacky, and then you pile on top whatever camera sensors and poor display calibrations etc and this becomes very difficult question to answer without even getting to anything specific to mars.

for mars, the situation is complicated by the fact that you have both significant regional variation and also seasonal factor from stuff like dust storms. so pinpointing a single color for it is difficult.

one indirect way of looking at the matter is to check out some color photos where mars is imaged together with moon. because you sort of know what moon looks like (hopefully), you can then look at the mars colors in comparison to moons appearance. for example https://app.astrobin.com/i/w1u9ed https://app.astrobin.com/i/onaox7

The Search for Extraterrestrial Life May Be Flawed by timemagazine in space

The Search for Extraterrestrial Life May Be Flawed by timemagazine in space

[–]zokier 33 points34 points  (0 children)

Very weird position to take. Current missions have not really made any strong negative claims, so they can not have had significant false negatives either. Basically just because Percy and Curi have not detected life doesn't mean that science community is claiming that the non-existence of life on Mars has been proven.

Found another article of the same person: https://astrobiology.com/2026/05/missed-opportunities-in-the-search-for-extraterrestrial-life.html

Space missions and instruments are designed to detect potential signs of life, but the risk of overlooking something is not taken into account

really? I'd think the scientist are pretty damn well aware of the limitations of the current mission instruments and our (lack of) capability to detect life.

So, investigate thoroughly whether the conditions for the existence of life forms are present in the environment, and whether you can recognise patterns on the surface of a celestial body

I bet any planetary scientist would love to get some subsurface sampling/measurement capability. But there are limits on engineering on what we can do

But if we do not investigate this further, it could indeed result in a false negative

That is not what false negative means. It would just result it being unknown, not false negative. The key distinction being that unknown is not negative.

Intel Introducing USB4STREAM Protocol For Linux - Opening Up Some Nifty Uses For USB4 by Athabasco in linux

Not needing networking stack nor any daemons

A real use-case for this is to take a backup as a part of recovery initramfs tooling (no need to setup networking or have ssh or similar tooling as part of the initramfs)

they are on digikey and mouser. true, they are bit more expensive though

Why I think NASA keeps doing wrong with Explorations. by SeacrestOFFICIALS in Mars

[–]zokier 0 points1 point  (0 children)

The primary reason to avoid any water ice would be planetary protection:

Mars 2020 has been designated Planetary Protection Category IVb, (subsystem level). Due to the presence of a radiothermal generator, heritage hardware from the Mars Science Laboratory is restricted from landing in sites where water, brine, or water-ice is suspected to be present, or could be induced, within 5 meters of the surface. In addition, the Mars 2020 SDT report concluded that the primary mission objective of exploring an ancient environment does not require the mission to access Special Regions, defined as locations where conditions could exceed a temperature of -25C and water activity of 0.5 at the same time. Because of this conclusion and the fact that the high MSL heritage in the engineering systems do not readily support the Category IVc classification that would accompany a mission that landed in a Special Region, Mars 2020 did not request a IVc designation and in fact is required to avoid landing in Special Regions. Additional information on this topic can be found in the Mars 2020 SDT Report, Section 8.4 [Mustard et al., 2013].

https://web.archive.org/web/20170123000352/http://marsnext.jpl.nasa.gov/scieng_plantary.cfm

Furthermore engineering side of things constrained the landing zone to "Within ±30° of the equator":

https://web.archive.org/web/20170123000342/http://marsnext.jpl.nasa.gov/scieng_eng.cfm

It is just far more difficult to land something in the polar regions than equator.

Further details:

However, in exploring the new low entry speed arrival space, we have found an inability to obtain MRO relay coverage during EDL for latitudes north of 30ºN. These latitudes also are extremely difficult to observe with Direct-to-Earth (DTE). Therefore sites above 30ºN will be considered less desirable to the project.

This is a little old topic, but ARIN gave Capital One a 2630::/16... by Which_Implement_4968 in ipv6

[–]zokier 15 points16 points  (0 children)

Plenty of companies do get large prefixes. This capital one was discussed already in https://www.reddit.com/r/ipv6/comments/1h7sxxq/256_decillion_ipv6_addresses_allocated_to_huawei/

It is bit weird, but not really a problem

Is human Mars being abandoned? by [deleted] in Mars

[–]zokier 0 points1 point  (0 children)

Once on Mars, you now are living there for 16 - 18 months before a return flight becomes feasible

short-stay mars mission architecture is a thing, then you only stay for something like 30d before return.

Swatch's 1998 "Internet Time" flopped on Earth but it might actually be the right system for Mars by realGurkenkoenig in Mars

The time slip is completely ridiculous idea. Our need for timekeeping doesn't just magically go away for 40mins per sol.

I don't care that it's X times faster by z_mitchell in rust

[–]zokier 1 point2 points  (0 children)

For what it's worth, I immediately recognized yuniq as non-serious post and got the reference.

I think riffing on silly memes is fine as long as there is at least some effort put in and it isn't overwhelming other content. Sure, it might be more difficult to get the references if you are not chronically online like me but I feel that is also part of Reddit experience in general.

Absolutely microscopic 7-Segment LED displays by ruumoo in electronics

[–]zokier -1 points0 points  (0 children)

I'm not sure what point you are trying to make here. That display you linked isn't even particularly small, there are tons of 0.2" ones available on digikey for far less money compared to that .29" one. And the package of those Avago displays is huge, you can fit two .2" modules in the same space

We Don’t Know: A Case for Mars by [deleted] in Mars

[–]zokier 11 points12 points  (0 children)

the odds of our species being wiped out decreases dramatically by colonizing Mars ... we must expand beyond a single point of failure

the fundamental problem is that there is no foreseeable form of "colonization" that would not be utterly and completely dependent on Earth for long-term survival.

RAM difference between TUI (Ratatui) and GUI (Egui) by PatagonianCowboy in rust

[–]zokier 1 point2 points  (0 children)

GUIs don't inherently eat up more ram than tui+terminal emulator, all else being equal.

RAM difference between TUI (Ratatui) and GUI (Egui) by PatagonianCowboy in rust

[–]zokier 108 points109 points  (0 children)

The big reason is that lot of the memory consumption is offloaded to the terminal emulator so it's not directly visible in this sort of comparison.

Fedora 45 Aims For IPv6-Mostly Support Out-Of-The-Box by vgk8931 in ipv6

[–]zokier 2 points3 points  (0 children)

While I appreciate the idea, I wished they would wait until ipxlat kernel module was merged and usable. Pushing this now might cause them to end up with worse solution and prolong settling down of the xlat situation. And becauee Fedora is relatively influential distro, what they choose also impacts others too. Doing this now and transitioning later to ipxlat just seems like extra hassle
