nickwitha_k (he/him)@lemmy.sdf.orgto Ask Lemmy@lemmy.world•When scientists come up with the hypothesis and antihypothesis for an experiment, are they usually orthogonal so its easier to form a range of effect for whatever cause or correlation is at subject?3·17 days agoIt’s been years since I’ve been in the lab but it really will depend a lot on the subject matter and the type of experiment.
If it’s a subject matter that is fairly well explored and defined, the alternative hypotheses might be fairly straightforward. Take, for example, an experiment from a while ago where entomologists suspected that desert ants navigate by using dead reckoning, effectively counting their steps, remembering their changes in direction measured by a biological compass, and integrating them together, in a process similar to “fusion” in electronic position sensors.
To validate part of this hypothesis, they needed to get more granular and isolate one part of it. So, they formulated a “sub-hypothesis” that stated that the ants had some sort of innate awareness of the distance that they covered with each step, knowing the length of their legs and this their stride length, similar to how cats know their healthy body width. The experimental hypothesis would be something like:
“Altering the length of desert ant legs will result in navigation failure with longer legs causing them to overshoot and shorter legs causing them to undershoot. The navigational trajectories should otherwise be identical.”
Building alternative hypotheses for this relatively simple experiment, prior to conducting it would be straightforward, as you appear to be suspecting. They could be as simple as:
“The length of the desert ant’s legs will have no impact on their navigation because they are not directly related. This will be apparent through the ants showing no discernable difference in the paths that they take when navigating, regardless of leg length.”
“The length of the desert ant’s legs will have some impact on their navigation but, they are able to compensate for discrepancies in stride length through some as of yet unknown mechanism. This will likely be apparent in statistically significant distance-related navigation errors in their paths.”
After the experiment, the data would be analyzed and checked for a match against the established hypotheses. If there is not a good match or there is an unexpected shape to the data, further experiments may be required to see if it is an anomaly or if something else might be going on.
(In this case, it was found that, yes, desert ants have some sort of innate awareness of what their stride length should be and changes in their leg lengths throw off their navigation, as expected.)
Now, when it gets to subjects that are less clear and established, alternative hypotheses can get a lot more challenging because often the difference between the data fit that proves or disproves a hypothesis can be miniscule. Or, the data points might form a completely unexpected shape that doesn’t match currently known phenomena.

It blows my mind how they manage to always act in bad faith. Always.
It’s pretty straightforward, imo, they built a feedback loop into their instance culture that encouraged social dopamine junkies to participate in toxic behaviors, valuing things like “dunking”, othering, and dehumanizing the out group (non-hexies) over things like factuality, good faith, and not being dicks.

Hey. How’d you get my notes?..I forgot where I put them so if you have some kind of trick or magic, it would be most helpful.

In my experience often detriment. Most of the images for projects that I have been encountering as of late - hell, most Dockerfiles that I’ve been encountering - have hardware-specific config and packages. I just want a Dockerfile or maybe a docker-compose.yaml that is hardware neutral by default and doesn’t use the shitty throttled Dockerhub for its base image.

nickwitha_k (he/him)@lemmy.sdf.orgto Linux Gaming@lemmy.ml•Gaming on Linux hasn't been great so far...2·1 month agoyou answered my second question but not in the way I intended, I meant to ask for more of a methodology like, do you just read the man pages? do you refer to AI? are you just full trial and error? does your work provide resources? Im asking because I generally want to see why its such an issue for people to find info, personally I use a mix of selfhosted AI and various forums and wikis. I wouldn’t be supprised if some users are learning 100% through chatgpt or a single youtube channel.
My recommendation would vary depending on use case.
If just gaming, yeah. Your approach sounds sane.
If wanting to tinker, develop, or, honestly, even do stuff like deploying local LLMs and the like, I would strongly encourage gaining familiarity with manpages. For anytime where precision and accuracy are necessary, like low level tinkering, I don’t believe that should trust LLMs. Learning how to find relevant info in manpages and dev reference materials will save a huge amount of time and heartache.
On the one hand, conservatism, an authoritarian, pro-oligarchic ideology has no legitimate place in a democracy. On the other, mass murder is still bad, mmm-kay.

I can verify that the OS fails to see the microphone and webcam when switched off. This was really confusing the one time that I wanted to use them.

nickwitha_k (he/him)@lemmy.sdf.orgto Linux Gaming@lemmy.ml•Gaming on Linux hasn't been great so far...4·1 month agoOpen question to all: what is your level of profiency?
I’d say that I’m pretty proficient. I haven’t done LFS yet but haven’t really spent more than a few mins with windows except for a handful of times for about 15 years. The one time that I did so recently was to try to get a PSVR2 to work. That experience was so awful (driver disks for OS install, ADS FUCKING EVERYWHERE THAT CANNOT BE DISABLED, etc) that I quickly gave up and ended up killing the VM. I’d dinner become a hermit in a cave than abide by OS-level ads that can only be partially disabled by mucking around in the registry.
Sorry. A bit off-topic. I just really hate ads. Erm… I’ve done some basic tutorials on writing drivers for the kernel and have been working on reverse engineering a driver for some AR glasses, though I’ve not made it too far.
How do you learn about linux?
My initial learning was because I lost my XP serial in college and decided to give Linux a try. From there, a lot of my learning has been through work, which I got due to my teaching myself how to use Linux.
Do you think there is a problem or is it a loud minority of users?
It’s both. I’d say that it really is going to vary based upon the sub-community. Unfortunately, there’s a lot of toxicity in the gaming community at large, which, in my experience, is reflected in segments of Linux gaming communities. On the other hand, I just last night saw a bunch of people on Lemmy trying to help someone figure out how to get their new GPU to work, which was very much the opposite of toxic.
You nailed it, IMO. However, I would like a real artificial sentience of some sort just to add to the beautiful variety of the universe. It does seem that many of my fellow humans just want chattle slaves though. Which is saddening.
