It's been calculated that individual climate action can sum to 25-27% of the needed carbon reductions. Sure this is nowhere near enough, but it is significant!

So I'd please like to stop seeing posts which implies that individual vs collective action is an either/or. We need both!

@dimi Yeah, the focuse on use is an issue. And in my environmental group there's concern about the wording around "keep products for 7 years" on that site because that number was calculated for electronics, & assumes you're not getting another one in the meantime.

Good to keep other items as long as you can too, but electronics makes the most difference!

@alcinnz@floss.social avatar

@dimi And agreed: Figuring out what advice to give is difficult.

That "Take The Jump" site makes a solid effort, & having localized sister sites should help give better advice. Because like for your example of electric cars, whether that's advisable depends in part on where you live & how good your transport infrastructure is!

@alcinnz@floss.social avatar

@dimi I'll take it under advisement!

@alcinnz@floss.social avatar

@dimi I'm sure you'd know better than me, but my understanding is that electric cars are more of an improvement for urban. Not that they were bad for rural.

Also that it does take a fair amount of energy either, but especially electric.

@dimi 1. Aggregating the fuel burning into electricity improves efficiency even if it is still fossil fuels.

  1. In New Zealand, our electricity grid is near-entirely renewable. Mostly hydro.

  2. Personally I don't advocate any type of car. I prefer electric scooters, walking, bus, bikes, etc. Though yes, this is me being an urbanite.

@dimi 4. I'm sure there's more nuances to keep in mind, but I'll leave that to engineers to discuss.

Studying Shadow's commandline tools...

After initializing LibShadow, internationalization, & auditting lastlog parses/validates commandline flags ensuring no args remain, opens /var/log/lastlog retrieving its filesize, either updates or prints to it, & closes it. Updating involves between validation & flushing querying password entries to update. For each relevant entry it seeks to that offset in the lastlog & writes a binary structure with audit logging. Printing gathers more info.

... either validation or sorts the files, & cleans up with error messages & exit codes. The validation involves iterating over each entry skipping NIS lines, & prompting what to do about any syntax errors, duplications, etc it finds depending on their severity. This is implemented seperately for the shadow file.

newusers checks privs & that the shadow files are present, opens all the accounts files, repeatedly reads lines from stdin, reports any errors, cleans up, & copies info over to PAM if supported. For each stdin line once validated newusers splits it into 7 fields, locates the password entry, validates a bit more, writes out the parsed group then user if valid, locates the password entry, generates & writes the hashed password, outputs password entry, & outputs/allocates subordinate IDs.

8/8!

This is your irregular reminder are fucking dicks:

> Adobe Tells Users They Can Get Sued for Using Old Versions of Photoshop

We need tools to get to the point where they can replace Adobe tools. Open alternatives are great, but they are sadly not there yet to replace Adobe tools for professionals.

And won't be unless projects like @inkscape get enough funding to develop to a point of being viable alternatives.

Yes, it is in no small part about the money.

@doctormo @jlapoutre @rysiek @inkscape Just the other day I remarked on a disconnect where FOSS-adjacent folks who don't trust opensource UX to have improved, & FOSS folks who don't trust them to be judging based on our current state.

I don't know what to take from this dynamic beyond meaningless noise to disprove...

@villewilson @rysiek @Blender What if you're at a studio who has built extensive tooling around Maya because Blender didn't exist when they started? I've heard that story before.

Not that Weta's actually using Maya anymore, but it's a load-bearing abstraction for them. And I would agree that Blender's better built for that purpose!

alcinnz,
@alcinnz@floss.social avatar

@villewilson @Blender @rysiek Agreed, major (and relatively old) effects studios like Weta are exceptional cases.
