Another longtime JD user here, I'd love to hear what your reasons are for each of these!

Cheers! I'd like to pass on this info though, for anyone who enjoys both like myself:

Caffeine drinking potentiates cannabinoid transmission: interaction with stress effects - Neuropharmacology 2009

Our data suggest that the cannabinoid system is implicated in the psychoactive properties of caffeine and in the ability of caffeine to reduce the pathological consequences of stress. Chronic caffeine assumption sensitized GABAergic synapses to the presynaptic effect of cannabinoid CB1 receptor stimulation by exo- and endocannabinoids. The synaptic effects of caffeine were slowly reversible after its removal from the drinking solution. Furthermore, although exposure to caffeine for only 24h did not produce measurable changes of the sensitivity of cannabinoid CB1 receptors, it was able to contrast the down-regulation of CB1 receptor-mediated responses after social defeat stress.

I copied the rest from bloommedicinals.com, just the relevant bits. Also added the links to the studies and the pages with additional descriptions.

TL;DR:

  • Low levels of caffeine can help to maximize the effects of THC, but too much caffeine can lessen the impact of your cannabis
  • Caffeine and THC can both increase dopamine levels, but too much at once can trigger anxiety, agitation, and paranoia

What Happens When You Smoke Weed and Drink Coffee?

Since coffee and cannabis may offer so many health benefits on their own, you might think it’s safe to assume that enjoying a little bit of weed with your coffee would be okay. The reality is … it might be safe for most, but not for all. Here’s why.

THC and coffee can boost the amount of dopamine in our systems. Although dopamine can promote feelings of happiness and euphoria, too much of it at once can trigger anxiety, agitation, and paranoia. In addition, both caffeine and THC can both increase your blood pressure and heart rate.

This is why many doctors advise that those with heart conditions and those at risk of heart arrhythmia or stroke, should not mix caffeine and THC. So, if you’re new to mixing coffee and cannabis, it’s important to consult your doctor to make sure it makes sense for you. If it does, begin with lower amounts of coffee and cannabis than you would normally consume on their own. Then if needed, you can increase your dosage slowly.

Back in 2014, a study was conducted to measure the effects of mixing caffeine and cannabis on squirrel monkeys. The results of this study were published in the Journal of Neuroscience. (also described here)

The monkeys were given the ability to self administer cannabis whenever they wanted. All they had to do was to pull on a lever. When the monkeys were given low doses of a substance similar to caffeine, they seemed less likely to reach for the THC. But, when they received high doses of caffeine, they seemed to reach for that lever more often.

Then in 2018, a study led by Marilyn Cornelis at Northwestern University’s Feinberg School of Medicine seemed to back up these findings. This time, the study examined the effects of mixing cannabis and coffee on humans. It found that the more caffeine people consumed, the less cannabis their body was able to metabolize. (also described here)

So, although small amounts of caffeine can help your THC go a long way – too much caffeine can lessen its effects.

Hi JB, I went down this rabbit hole last week, here is a post I made summarizing what I found, with links to the dev's GH discussions of the different ideas for implementing the linking of communities, both within an instance or across instances, public or private, mod or user created. These features would likely be implemented separately.

There is also a link to a firefox extension that you may find useful while the dev work is ongoing.

See https://lemmy.ml/post/1615183

 

Good morning, lemmonheads!

P.S. in the meantime, a user has created a FireFox addon that might be useful, I have not checked it out myself.

Multilemmys (lemmy.ml)

Hey everyone! After my first week of settling in here, I think what would give my lemmy experience the biggest boost of any single added feature would be Multilemmys (or Multicommunities), so we can see the combined feeds of multiple communities in a single streamlined feed. I guess the purpose of this post is to spread awareness of this as a concept and point to the ongoing discussion on Github:

Support for grouping communities / multi-communities #818

Cross-instance 'multireddits', that are also automatic and topic-based #1113

Community Grouping #3071

I have seen users post that this was how they initially thought the fediverse would work when it was explained to them. I thought this would be the case as well when I joined.

(Edit to add: an older post with discussion on this idea including devs' thoughts at that time which shed light on why it does not work this way.)

Although I am new to this world, I feel this is one of the most intuitive abilities associated with the concept of the fediverse and that it MUST eventually be possible, the sooner the better.

This is similar to "multireddits", and the equivalent way to use them would be to combine feeds from different communities that are on the same instance, so for example I have one multilemmy to combine the feeds from /c/politics, /c/news, /c/worldnews, /c/worldpolitics (all on lemmy.ml).

Then additionally with Lemmy we have equivalent communities hosted across various instances, and it would be a new and different kind of ability to be able to combine these into a single multilemmy, so for example I have a multilemmy combining lemmy.ml/c/politics, lemmy.world/c/politics, beehaw.org/c/politics, etc.

I found this idea mentioned a few times around lemmy, where @deadcyclo@lemmy.world and @communist@beehaw.org pointed out the above open github tickets for these ideas.

Those github discussions were a fascinating read for me! Its clear that the boffins have already put a fair amount of thought into these possibilities, and identified questions that will need to be answered such as

  • how to deal with communities that have the same/different name but are or are not actually the same subject
  • duplicate posts and/or cross posts
  • whether to cause automatic/default links or not
  • how to implement this in a way that is of most benefit to the health of the lemmy ecosystem
  • there seem to be two separate use-cases also: one being communities intentionally linking to share content and the other being a user creating their own custom combinations, either for personal or public use.
  • how to handle subscriptions

Discussion continues even this week! After reading through all the ideas, I don't have any specific preference but I am excited to see what they eventually decide to implement as I'm sure it will be rewarding. Personally I think getting some cross-instance version of this should become a priority as soon as they feel they've adequately responded to the reddit migration, which I imagine would be a month or two down the road.

I gotta end by saying how happy I am to be here after leaving Reddit, this really feels like the start of something incredible. Cheers!

Not at all: Not if you avoid purchasing anything involving tipped-services! People who pay their workers so little that they need to be tipped tend not to get my business.

 

This guy's project is tremendous:

"Carbonating tap water to make seltzer is easy, fast, and absurdly inexpensive with my improvised apparatus. All that is required is to place CO2 gas in agitated contact with chilled water for a few seconds. In this essay, I'll show you how it is done with easy-to-find parts and common PET soda bottles. I'll also explain the kinetic chemistry of why it works so well. And in the second half of this essay, I'll explain how I progressed from this improvised apparatus to installing a complete soda fountain in my home."

Thanks!

I don't seem to be able to find the m3u8 in network tab with Firefox, so not sure if thats my fault or if youtube changed something. I'll think to search for the m3u8 in the network tab next time I encounter a blob elsewhere, though.

I often have trouble trying to get VLC to work with videos on youtube directly, and it didn't seem to like the blob link from youtube as described by this article, I assume youtube changed something and VLC hasn't been updated to keep pace.

(Article is from 2021)

So strictly speaking, blobs themselves still cannot be downloaded but it is often possible to find the stream link which will work when a blob is being used.

 

Today I learned how to tell VLC to use an audio track which is in a separate file, to play with the 4k video file I was watching.

It's not hard, as the linked docs explain:

  • Go to Media -> Open Multiple Files....
  • In the Open Media window, click Add....
  • In the Select one or multiple files window, select the desired first media (the video file) and add it.
  • In the Open Media window, tick Show more options, then tick Play another media synchronously. Click Browse and add the second media (audio to play).
  • Then click Play
  • (You may need to manually select the correct audio track if there is more than one now)

Of course if you need to synchronize the audio and video better you can go to the menu and select Tools > Track Synchronization to adjust as needed!

I'd gotten the video and audio separately via Invidious from youtube, because there seems to be no way to get a file for 4k video which includes audio straight through the UI. (Is there a good way to get a single file off youtube with 4k video and audio via some site so I don't need to merge or sync them manually?)
