Any idea who they plan to use for fabrication?
fascinating, thanks.
no doubt ushered in under some notion of “protecting” us from well funded groups, yet mysteriously didn’t include a minimum threshold so poor folks with $4.25 in their account are still included in these broad sweeping laws.
+1 for huygen optics, this dude is legit
out of interest, whats the deal with banks needing to know where you sleep at night?
is it a serfdom thing?
or is it only in the case of eg. that being the place you hold a mortgage with them on?
@op looking back, what was the specific cringe aspect of what you described in your story?
that you’d hope for this seemingly impossible outcome, of being a positive force in an established group with a clear bigoted direction?
or that you feel foolish for relapsing into believing religious topics again?
or something else?
may i ask why you believed that and why you stopped believing?
what piece of knowledge changed things for you?
surely you already knew all the reasons why that sounds pretty fantastical, even back then?
tangent away mate
seems like i’m mostly telling people in this thread not to feel bad about their prior cringe…
i really didn’t follow this closely AT ALL. but i feel like back in the day libertarian ideas were much more left of center than they are now. to my inexpert perception, it feels like libertarianism (and alot of other things) have been co-opted by conservatism over the years.
which version of the hollow earth are we talking? if you mean a giant hollow shell, then yeh i’m not sure how well supported that is.
if you mean the honeycomb earth idea, where there could be myriad of huge deep caverns. then i’m kinda open to that possibility.
(not that my geoscience knowledge extends beyond highschool geography and the odd wikipedia article - so would welcome an opportunity to discuss with someone adept.)
5·2 months agothis is a complex topic and probably belongs in a different thread.
essentially i don’t personally believe in punishing citizens of a country for the actions of its politicians.
at best its misguided, at worse it basically empowers politicians on both sides who draw power from friction between citizens of different nations. typical divide and conquer bs.
why do you not think a software developer wouldn’t have to
wouldn’t or shouldn’t? if you mean wouldn’t, it’s not surprising and its not the dev’s fault they have to comply with policy, so the criticism is not with them.
if you mean shouldn’t, i don’t agree with punishing athletes either, but regarding foss specifically, isn’t the “friendly competition” of olympics equivalent to that? sort of. in some ways yes. in other ways its actually the opposite.
collaboration is actually the opposite of competition.
and while there’s a case for the benefits of healthy sports competition, i don’t believe it truly fulfills the spirit of international goodwill to the degree it says on the packaging. foss and other forms of international collaboration for the betterment of greater society are definitely on a higher rung - in my opinion at least.
personally i don’t agree with sanctioning foss communities.
but fuckit, bring on more forks i say.
among other benefits, the scifi-type scenario of nations trying to patch eachothers backdoors and slip in new backdoors (and hopefully innovations). could make for an exciting OS space-race type scenario
its BIG. could be great to see some different teams tackle different issues.
for example a transcode team to tag and convert different media to the latest efficient formats might save alot of space.
and eg. voice-only recordings could be suitably encoded vs music etc
also some methods for diffing snapshots, or some kind of compromise on snapshots storage with minimal changes? not ideal but might be enough to get across the line maybe?
re. the “most important”, aside from specific items or archives, imo a crucial role might be text-only snapshots of most of the web. would help increase accountability amongst modern media outlets, journalists etc
incredible! can you please describe it a little more, how it worked and especially what the jets did and how that was pleasant vs being bombarded in an unpleasant way. what type of stream was coming out of the jets?
reddit is a cesspit, on reddit it used to be that misinformation or incompetency cope would be promptly identified, now its the top 5 comments on any thread…and the next 5 are circle jerks.
in other words: welcome reddit refugees. please please feel free to leave the reddit mindset at the door on your way in :)
gonna use this as an opportunity to launch my ted talk:
there’s no such thing as anything but “race mixing” since every single human on the planet is a mix of different ancient races anyway
(or to put another way, race is a bs term anyway since we’re all homosapiens)
Below is my general sleep guide.
From your post these points sound the most relevant:
- Once in bed, no work/study/planning thoughts. Identify and then free your mind of any thought patterns which keep your mind going. Resolve to address them at another time.
- You can even pre-allocate a time to resolve them during regular waking hours. eg. before getting into bed, remind yourself that any thoughts which ‘need attention’ will be resolved at ‘12pm tomorrow’ or ‘during your commute’ etc. If they pop up during the night, you already have a precooked answer which doesn’t involve waking your brain up even more.
- Don’t keep looking at the clock or trying to calculate how many hours of sleep you can get.
- Avoid looking at phone screen once you’re in bed, if you need to adjust volume use buttons or remote etc with your eyes still closed.
General
- Observe if caffeine plays a role, you can eg. avoid it after lunch or after dinner - whatever works for you & your body.
Late Evening
- Avoid cold (bluer) colour lighting & use warm (redder) colour lighting from late evening until bed. This is important and melatonin effectiveness is directly controlled by this 1. To put it very very simply, we’ve evolved for redder light = sunset->sleep, bluer = day->awake. Angle of the light can also play a role if you want to go deeper into it.
- Schedule blue light filters on your phone & computers. Should be standard on modern phones & use something like f.lux for computer 2.
Before Bed
- Avoid alcohol, lots of sugar or sugary drinks for at least an hour or so before bed.
- Some other otc/“natural” sleep aids to consider: l-tryptophan, valarian, hops, passion flower, chammomile. There’s some ‘complex’ products which are basically derived from these kinds of things eg. 3. [Always check anything you take for possible interactions with eachother or medication you’re on].
- Supplements like magnesium can help reduce effects of muscle tension.
- Ensure any herbal teas or other foods, drinks etc don’t contain more caffeine than you’d planned for. eg. some chocolates contain caffeine.
- Showering or bathing just before bed can help you relax.
In Bed
- Once in bed, don’t keep looking at the clock or keep trying to calculate how many hours of sleep you can get.
- No work/study/planning thoughts. Identify and then free your mind of any thought patterns which keep your mind going. Resolve to address them at another time.
- Is temperature or air flow effecting you? Some people find an oscillating fan can help regulate the airflow & temperature, and the repetition can be soothing.
- Are sounds keeping you alert or waking you up? Consider fan, white noise machine or rain sounds 4. You can adjust the EQ to mask specific problem sounds, eg. bass for thumps, mids/high for clatter or voices etc.
- Is light making problems? eg. light from electronics in standby mode, light coming through or around edges of windows, other lights in the house? Identify and cover them or your eyes as needed. Remember blue light is not your friend at this time, blue LEDs might look nice but can mess with the brain chemistry of sleep 1
- Avoid looking at phone screen once you’re in bed, if you need to adjust volume use buttons with your eyes still closed.
Sound
Falling asleep to sounds can sometimes help. Different people like different things on different occasions: music, YT, movies, TV, audio books, ambient soundtracks (rainforest, crackling fire), even boring monotone talking can be good. Avoid any ads if streaming or TV as they’re designed to grab your attention.
There are music genres almost designed for sleep, various ambient genres can be great especially if they employ low frequency variations and alpha, theta and delta wave type transitions 5. There’s a bit of bs around this, but also some legit bio-entrainment science too. In general find what works for you.
If listening, consider using your phone & use a sleep timer app on your phone to automatically gradually lower the volume and switch off after a scheduled time, this can help avoid being woken up by it later in the night. Find the timer periods which work for you. Also ensure your alarm will still wake you.

Here’s why knowing the above i still donate to wikipedia.
Because we don’t want them to be in a position where they take money with strings attached. Imo its good for them to be reminded they serve the public first and foremost.
