Title pretty much. Some days ago I noticed several of the frequent posters that made this community so enjoyable and lively have left and stopped posting here, supposedly due to some behind the scenes drama....
TLDR: some don’t like the moderation here, which is done by a single mod, and have gone and made their own community over on lemmy.world.
If this drama was real and the instance admins knew about it, I think I’d be happy to conclude that the instance admins did a bad job here given their status as a star trek instance. If there was a split amongst Risa people and its mod, then create another community (with TenForward being a great name for it) with a different moderator and let them co-exist as part of the same federation.
Now there’s probably some unnecessary fracturing (which is fine, that’s what the fediverse is all about in the end) … and I can’t help but wonder if the admins here are maybe a tad too much used to a reddit culture of allowing mods and admins get away with things … which is of course me being rather quick to judge, I can only speculate here clearly, but still … kinda funny to see.
I’ve been thinking lately about the concept of the fediverse and repurposing it toward the goal of creating a free and open, decentralized, federated network of vendors that run instances or groups of vendors that run one instance together. These instances would broadcast inventory updates to each node that they federate with....
It’s an interesting idea! I think there are many such applications for federation protocols.
A few thoughts/questions:
Ideally you’ll need a stable identifier for each specific product. Most small online stores I use have product names riddled with typos, so a way to tackle that would be nice.
What’s the data model? Would each store be an ActivityPub Actor? Like each one would have a username and publish inventory updates?
Where do these updates go (maybe something akin to a Lemmy “community”)?
If you’re just relying on stores’ self-reported stock levels, where’s the benefit of using a federated model? Could you just build an open source app that scrapes retailers’ websites and collates that information?
Is the eventual goal that this competes with Amazon et al? I.e. it becomes an actual marketplace, perhaps with a “buy” and “sell” Action, and where vendors’ instances are effectively web stores?
My goal is to cut out the middleman and allow vendors to wrestle back control from services like Amazon. I work in the film industry where we watched our suggestions to studio heads get ignored.
To give you an idea of how I tend to think, years ago, my idea was this to solve the fragmentation/walled garden problem in video streaming:
every company submits video content to a central store
users can watch anything they want. They just have to pay a monthly fee
that fee gets divvyed up to the companies that produced the media watched. Money only goes to companies that had content that was viewed and is a direct percentage of the monthly revenue of each user.
Ideally you’ll need a stable identifier for each specific product. Most small online stores I use have product names riddled with typos, so a way to tackle that would be nice.
Ideally, I’d start in a budding industry, slowly building and iterating upon an industry stylebook for their retail items that can be iterated upon by all users who are able to submit merchandise. I’m thinking of a whole separate place where the structure of each industry’s API can be tuned and made polymorphic with related but different item types.
What’s the data model? Would each store be an ActivityPub Actor? Like each one would have a username and publish inventory updates?
That’s the current vision, though I could also see an ecosystem of incentivized crowd-sourcing of out-of-reach inventories. That’s another idea I have concerning decentralized oracles but, if crypto tied into this retail thing eventually, a lot of the cool new technologies that crypto offers (digital identity, oracles, SPO’s that operate alongside instances, and so, so much more) could certainly come along for the ride.
Where do these updates go (maybe something akin to a Lemmy “community”)?
A lot like a Lemmy community but reformatted to work with inventories. Think of any web store. It could be identical to that but the data could be coming from multiple sources at once. I think there could be so many different possibilities for how this data could be mapped onto a front end that that I’d hate to pigeonhole this based on my preconceived notions…the flexibility might even be part of the beauty of this idea.
If you’re just relying on stores’ self-reported stock levels, where’s the benefit of using a federated model? Could you just build an open source app that scrapes retailers’ websites and collates that information?
I was actually attempting to do that but then quickly came up with this idea instead because it felt like I wold be further contributing to enshittification in an entirely enshittified dystopian hellscape if I just did the same thing as everyone else again. So many other sites contain warchests of scraped metadata. Very few are truly egalitarian like the fediverse can be, IMO.
Is the eventual goal that this competes with Amazon et al? I.e. it becomes an actual marketplace, perhaps with a “buy” and “sell” Action, and where vendors’ instances are effectively web stores?
Buying and selling features will be essential to draw people away from Amazon. Problem is, that’s one of the hardest probems to tackle in an elegant, dependable way. I can see similarities to OpenBazaar using a atomic wallets that accept any kind of crypto and convert it to any other…but I intend to spin this tech up with existing technologies to start.
Don’t know if we already have this but if not, this could be a new breath for running away from Google’s polluted, hard to find any real useful stuff SEO World. With Kagi’s optimization for activity pub, it’s easier to find content within the Federation. With a blog system that supports activity pub, people can get...

I am currently running most of my stuff from an unraid box using spare parts I have. It seems like I am hitting my limit on it and just want to turn it into a NAS. Micro PCs/USFF are what I am planning on moving stuff to (probably a cluster of 2 for now but might expand later.). Just a few quick questions:...
My current setup is 3x Lenovo m920q (soon to be 4) all in a proxmox cluster, along with a qnap nas with 20gb ram and 4x 8tb in raid 5.
The specs on the m920q are: I5 8500T 32gb ram 256gb sata SSD 2tb nvme SSD 1gbe nic
On each proxmox machine, I have a docker server in swarm mode and each of those vm all have the same NFS mounts pointing to the nas
On the Nas I have a normal docker installation which runs my databases
On the swarm I have over 60 docker containers, including the arr services, overseerr and two deluge instances
I have no issues with performance or read/write or timeouts.
As one of the other posters said, point all of your arr services to the same mount point as it makes it far easier for the automated stuff to work.
Put all the arr services into a single stack (or at least on a single network), that way you can just point them to the container name rather than IP, for example, in overseerr to tell it where sonarr is, you’d just say sonarr:8989 and it will make life much easier
As for proxmox, the biggest thing I’ll say from my experience, if you’re just starting out, make sure you set it’s IP and hostname to what you want right from the start… It’s a pain in the ass to change them later. So if you’re planning to use vlans or something, set them up first

<p>In a newly published study from the journal <a href="https://doi.org/10.1016/j.bbi.2023.05.010"><em>Brain, Behavior, and Immunity</em></a>, researchers have uncovered a surprising connection: Individuals with higher levels of inflammation, as evidenced by a marker known as C-reactive protein, tend to use social media more frequently.</p>
<p>Historically, inflammation has been linked to numerous health conditions, ranging from heart disease to rheumatoid arthritis. On a psychological level, prior research has suggested that systemic inflammation might influence behavior — particularly social affiliations, which makes sense from an evolutionary standpoint. When our ancestors faced infections, they might have been compelled to seek out social connections to increase their chances of survival. However, in today’s digitized world, social media platforms serve as a significant outlet for these affiliations.</p>
<p>For researchers David Lee, Tao Jiang, Jennifer Crocker, and Baldwin Way the relationship between inflammation and our modern-day social interactions held more to unpack. Drawing on recent evidence, the present research posited that higher inflammation levels might be associated with increased social media usage. This is based on the theory that inflammation can enhance motivations to seek out social connections — in a modern context, this is done namely through platforms like Facebook, Twitter, or Instagram.</p>
<p>To investigate this theory, the researchers conducted three studies with a combined total of 524 undergraduate students from three different Canadian universities. These students provided blood samples to measure C-reactive protein levels, an established indicator of systemic inflammation. They also filled out questionnaires about their social media habits, capturing details such as the frequency, type, and duration of their usage. This approach allowed the scientists to gauge if there was a direct link between inflammation markers and online social behavior.</p>
<p>Even after adjusting for potential confounding variables such as gender, personality traits, and depressive symptoms, a clear pattern emerged: students with higher C-reactive protein levels reported more frequent and prolonged social media use. In other words, participants with more inflammation were seemingly drawn more towards social media, perhaps as a modern-day method to fulfill their intrinsic social affiliation needs.</p>
<p>“The present study found that systemic inflammation is associated with more social media use among middle-aged adults and college students,” the researchers stated. “The study of inflammation and social behaviors on social media presents an intriguing opportunity to understand the social effects of inflammation in daily life.”</p>
<p>These findings shed light on a previously unrecognized link between our physiological state and our digital behaviors. The present research highlights a potential biopsychosocial antecedent to social media use. As we continue to understand the factors that influence our online habits, the role of internal biological cues might become an increasingly important area of study.</p>
<p>Like all research, this study must be viewed with an objective lens by acknowledging limitations. While the relationship between inflammation and social media use was identified, the study was correlational and does not necessarily prove that inflammation directly causes increased social media usage. Additionally, the research combined results from three individual studies, each with its own unique methodology and sample. This raises challenges in making direct comparisons. The study also broadly measured social media use, without diving into specific behaviors on individual platforms which might offer more nuanced insights.</p>
<p>The study, “<a href="https://www.sciencedirect.com/science/article/abs/pii/S0889159123001289">Can inflammation predict social media use? Linking a biological marker of systemic inflammation with social media use among college students and middle-aged adults</a>“, was authored by David Lee from the University of Buffalo, as well as Tao Jiang from Northwestern University and Jennifer Crocker and Baldwin Way from Ohio State University.</p>

Hi there! Looks like you linked to a Lemmy community using a URL instead of its name, which doesn’t work well for people on different instances. Try fixing it like this: !conservative
<p>In a new study published in <em><a href="https://www.sciencedirect.com/science/article/pii/S0010945223002897" target="_blank" rel="noopener">Cortex</a></em>, researchers have discovered that autistic adults exhibit a diminished neural response to their own faces compared to neurotypical adults, suggesting unique differences in self-referential processing. This research, using advanced brain imaging techniques, also indicates that these differences are specific to facial recognition and do not extend to how names are processed.</p>
<p>Autism, also known as Autism Spectrum Disorder (ASD), is a complex developmental condition characterized by challenges in social interaction, communication, and restricted or repetitive behaviors and interests. People with autism may have difficulty understanding social cues, may engage in repetitive behaviors such as hand-flapping or rocking, and often have intense interests in specific topics.</p>
<p>Past research has consistently shown that humans generally have a strong bias towards processing information related to themselves. This self-bias is believed to be crucial for social interactions and building accurate models of the social environment. Intriguingly, autistic individuals were found in previous studies to show potential differences in this self-referential processing.</p>
<p>Given the importance of faces and names in social interactions and their high relevance to oneself, understanding how these are processed differently in autism could provide key insights into the social challenges faced by autistic individuals.</p>
<p>“It has been becoming increasingly clear that there are differences in how individuals with autism process self-related information, and this may be linked to their social and communication difficulties,” explained study author <a href="https://annabelnijhof.com/" target="_blank" rel="noopener">Annabel Nijhof</a>, a researcher at Ghent University. “With a relatively new EEG analysis technique, we could investigate potential brain differences in the response to one’s own name and own face in little more than a minute, between adults with and without autism.”</p>
<p>To delve into this, researchers recruited a total of 58 adults – 31 with an autism diagnosis and 27 neurotypical individuals. However, due to various reasons such as inability to provide the necessary images for the face task, attention check failures, and technical issues, the final participant count was adjusted to 20 autistic and 24 neurotypical individuals for the face task, and 27 autistic and 25 neurotypical individuals for the name task.</p>
<p>The researchers employed a sophisticated brain imaging technique known as Fast Periodic Visual Stimulation with Electroencephalography (FPVS-EEG). This method involves presenting stimuli – in this case, faces and names – at rapid, periodic frequencies, allowing for the measurement of neural responses with a high degree of accuracy.</p>
<p>Participants were shown images of their own faces, faces of a close acquaintance, and faces of strangers, as well as their own name, the name of a close acquaintance, and unfamiliar names. The key was to measure the participants’ brain responses to these different stimuli and compare the patterns between autistic and neurotypical individuals.</p>
<p>In the task involving face recognition, neurotypical adults exhibited a stronger response to their own face compared to faces of acquaintances and strangers. However, autistic adults showed a reduced specific response to their own face, suggesting a unique difference in self-face recognition. This effect was not observed in the task involving name recognition, where both autistic and neurotypical adults showed similar patterns of neural response, primarily exhibiting familiarity effects (stronger responses to familiar names compared to stranger names).</p>
<p>These results imply that the diminished self-specific neural response in autistic individuals is particularly tied to facial recognition, and not to the processing of self-related information in general. This distinction is crucial as it sheds light on the nuanced ways in which social processing might be different for autistic individuals.</p><div class="addrop-wrap" data-id="64749"><p style="text-align: center;">

<p>“Adults with autism showed a comparable neural response when seeing their own face and that of someone close to them, whereas adults without autism show stronger responses to seeing their own face (a ‘self-bias’),” Nijhof told PsyPost. “Contrarily, neither adults with nor without autism show differences in the neural response to their own or a close other’s name. Thus, there do appear to be self-specific differences in autism, but not across all domains of information processing.”</p>
<p>However, the study is not without its limitations. While the study’s sample size was consistent with similar studies in this field, a more extensive participant base in future research could provide even more robust findings. This research opens the door to further exploration into how autistic individuals process various types of self-related information, which could have significant implications for developing tailored approaches in education and therapy.</p>
<p>It is also possible that the distinct neural response to one’s own name, compared to other names, might not be immediately apparent but emerge at later stages of cognitive processing. “Because we wanted to design an experiment that was very quick (it took less than 8 minutes per person to test them on all conditions), we may not have been able to pick up on (differences in) slower, more effortful and in-depth brain responses to seeing your own face or name,” Nijhof explained.</p>
<p>The study, “<a href="https://doi.org/10.1016/j.cortex.2023.10.023">Differences in Own-Face but not Own-Name Discrimination between Autistic and Neurotypical Adults: A Fast Periodic Visual Stimulation-EEG Study</a>“, was authored by Annabel D. Nijhof, Caroline Catmur, Rebecca Brewer, Michel-Pierre Coll, Jan R. Wiersema, and Geoffrey Bird.</p>

The wife of Bill Ackman, the hedge fund billionaire who accused Claudine Gay of being a plagiarist and led calls for her resignation as Harvard president, is now facing allegations of plagiarism herself.
Neri Oxman, a prominent former professor at the Massachusetts Institute of Technology, has apologized after Business Insider identified multiple instances in which she lifted passages from other scholars’ work without proper attribution in her 2010 dissertation.
In response to Gay’s resignation, Ackman published a 4,000-word post on X – formerly Twitter – in which he criticized diversity, equity and inclusion efforts as well as complained about “racism against white people”.
Gay had faced plagiarism allegations over her 1997 dissertation, but she requested corrections and was cleared of academic misconduct by a three-member independent review board.
Ackman additionally criticized Business Insider and the reporters at the publication who authored the story investigating Oxman, saying he would spearhead plagiarism reviews against the outlet’s staff.
Some consider her a celebrity in the field of architecture and design, and her new company – named Oxman – was in the middle of a soft launch when she issued her apology in response to Business Insider’s reporting.

Link aggregators have a problem on the fediverse. The approach is server-centric, which has positives, but it also has major negatives.
The server-centric approach is where a community belongs to a certain server and everything in the world revolves around that server.
The problem is that it's a centralized formula that centralizes power in a the hands of a whichever servers attract the most users, and potentially breaks up what might be a broader community, and makes for a central point of failure.
Right now, if [email protected] and [email protected] talk on [email protected] then a lot of things can happen to break that communication. if c.com defederates b.com then the communication will not happen. If c.com breaks then the communication will not happen. If c.com shuts down then the communication will not happen. If c.com's instance gets taken over by management that doesn't want person1 and person2 to talk, then the communication will not happen.
Another problem is that [email protected] and [email protected] might never meet, because they might be on [email protected] and [email protected]. This means that a community that could reach critical mass to be a common meeting place would not because it's split into a bunch of smaller communities.
Mastodon has servers going up and down all the time, and part of the reason it's able to continue functioning as a decentralized network is that as long as you're following people on a wide variety of servers then one server going down will stop some users from talking but not all of them so the system can continue to operate as a whole. By contrast, I'm posting this to one server, and it may be seen by people on a wide variety of servers, but if the one server I'm posting this to goes down the community is destroyed.
There are a few ways to solve the problem...
one method could work as something like a specific "federated network community". There would be a local community, and the local community would federate (via local mods, I presume) with communities on other instances creating a specific metacommunity of communities on many instances that could federate with other activitypub enabled communities, and if any of the federated communities go down the local community remains. If any servers posed problems they could cease being followed, and in the worst case a community could defederate totally from a server (at a community level rather than a server level) In that case, [email protected] and [email protected] could be automatically linked up once both connect to [email protected] (I'm thinking automatic linking could be a feature mods could turn off and on for highly curated communities), and if c.com shuts down or defederates with one of the two, [email protected] and [email protected] would continue to be able to talk through their federated network.
Another method would be something more like hashtags for root stories, but I don't know how server-server links would be accomplished under a platform like lemmy, kbin, or lotide. I don't know how hashtags migrate on mastodon type software and how that migrates. In that case, it might be something like peertube where a network is established by admins (or users, I don't know) connecting to other servers manually.
Finally, I think you could implement the metacommunity without changing the entire fediverse by having the software auto-aggregate metacommunities. You could create a metacommunity community1 on a.com that would then automatically aggregate all posts on communities called community1 on all known servers. The potential downside of this is you could end up with a lot of noise with 100 posts of the same story, I haven't thought much about how you could handle duplicates so you could participate but wouldn't have 100 similar posts. In this case with respect to how to handle new posts, each metacommunity would be a local community and new individual posts would be posted locally and federated to users on other metacommunities. If metacommunities of this sort became the norm, then the duplicates problem may be solved organically because individuals using metacommunities would see the posts on other metacommunities and wouldn't bother reposting the same story, much like how people see a story and don't repost in individual communities.
One big problem is scaling, doing something like this would definitely be a non-trivial in terms of load per community. Right now if one person signs up to one community, they get a lot of posts from one server. Under a metacommunity idea like this, if one person signs up to one community, they get a lot of posts from many, many servers. lemmy.world has 5967 total instances connected to it, and 2155 instances running lemmy, lotide, kbin, mbin, or friendica that could contain similar types of community, that's a lot of communities to follow for the equivalent of one single community, especially if some of the communities in the metacommunity have a lot of traffic in that community. You'd have to look at every known server to first see if it exists and second if it has a community appropriate for the metacommunity, and the metacommunity would have to routinely scan for dead hosts to remove from the metacommunity and live hosts that may start to see an appropriate metacommunity has been created.
I'm sure there are other solutions, but I'm just thinking of how things work within my current understanding.
Of course, for some people, the problem is one they don't want solved because it isn't a problem in their view (and that's a legit view even if it's one I'm not really amenable to). Some people prefer smaller communities, or want tighter control over their communities. For servers or communities that don't want to be brought into a metacommunity, it seems like some sort of flag to opt-out (or opt-in as the case may be) should be designed in -- I'm thinking something in the community description like a textflag NOMC or YESMC that server software would be designed to respect.
With respect to moderation, It seems to me that you could have a variety of strategies -- you could have a sort of default accept all moderation where if one instance moderates a post other instances take on the same action, or whitelist moderation where if one instance or one set of moderators on a whitelist take an action then other instances take the same action, or a sort of republican moderation where if a certain number of instances take an action then other instances take the same action, and probably an option for individual metacommunities to only accept moderation from the local community the original post came from. I suspect you'd want a choice in the matter per metacommunity instance on a server.
Solving the fragmented community problem is something I’ve been pondering too, and the meta-community idea you described seems interesting.
Obviously, a proper technical solution will be difficult. Federation comes with a host of challenges, as well as benefits.
Giving communities the opportunity to be open to other like minded people on different instances would be beneficial to the network, for a number of reasons.
If two communities on different instances have the same name, it doesn’t seem crazy to ask each of them if they’d like to federate with each other.
That way, apart from instances defederating, discussions could continue even if individual servers go down.
Of course, people love to hold on to their little fiefdoms, so the issue is as much social as technical.
I imagine it like friend requests between communities: [email protected], [email protected] and [email protected] could send each other friend requests and merge into one federated meta-community about x. Then if one instance goes down the other two are still there to keep the meta-community alive, and if one goes rogue they can just unfriend and keep going without it.
The nice thing about manual federation is that the communities don’t have to have exactly the same name, and the mods can keep malicious or troll communities out. And ofc you could still have client-side control if you want to, e.g. add or remove a community just for you locally, or create your own local meta-community.

Several pro-Moscow receptions are scheduled across the country in the coming weeks, one even featuring the far-right Kremlin ideologue Alexander Dugin. All is happening just months away from the EU elections, a “functional junction for the destabilisation of our democracies,” according to EP Vice-President Picierno...
Imagine a post from a tiny instance running on the cheapest VPS going viral and now all of the top Lemmy instances are trying to embed it from the tiny instance. It would immediately blow up.
That would increase the barrier to entry massively, and all that to save a few GBs of disk space. It’s small enough it wouldn’t even fill up half of my phone’s storage that I’m carrying in my pocket all the time.
What’s wasteful is the MBs of JavaScript you load on most modern website infested with all the video ads.
What Lemmy does is also very effective because each instance acts as a cache for the other instances. If any given post is viewed more than once from a remote instance, it ends up cheaper in CPU and bandwidth.
On bigger instances, the cost of federation is very small compared to the load of serving the instance’s users.
It also allows instances to have their own sorting algorithms, discovery algorithms, you name it. You have the data, you can crunch the numbers however you want for your users. You can develop your own spam filters and tools.
Even on my small 5 users instance, that’s 4 users worth of traffic that never hits the bigger instances. Probably more because I refresh the home page a few times a day whenever I open up my app to scroll a bit.
Power management on certain chips is simply better than anything Linux has to offer (AMD Zen+ mobile for instance)
Modular driver architecture with drivers that aren’t complete jank to manage and install. A lot of people see this as a pain point, but in reality it’s not such a bad thing, especially nowadays.
This is a given, but as lots of stuff runs on Windows (namely older games), you can only really make stuff for Windows on Windows. So if you need to develop Win32 software, you really have to use Visual Studio for proper development. Mingw cross compile exists, I know, but that’s never going to be as good.
Number 3 is keeping me on Windows. I make mods for old games and I need Visual C++. I almost got the compiler to run under Wine but who knows how it would behave if it did run.
<p>In a significant stride towards understanding Alzheimer’s disease, researchers have discovered that higher levels of certain fatty acids in the blood are associated with a lower risk of brain changes typical of the disease. This finding, published in <em><a href="https://doi.org/10.1093/gerona/glad248" target="_blank" rel="noopener">The Journals of Gerontology: Series A</a></em>, could pave the way for more effective early detection and management strategies for Alzheimer’s, a condition that affects millions worldwide.</p>
<p>Alzheimer’s disease is a progressive neurological disorder that primarily affects older adults, leading to memory loss, impaired reasoning, and changes in personality and behavior. It is the most common form of dementia, characterized by the accumulation of amyloid-beta proteins in the brain, forming plaques that disrupt cell function. Despite extensive research, Alzheimer’s remains incurable, and its exact cause is still not fully understood, making early detection and management strategies critical.</p>
<p>“The incidence of dementia is increasing over time, impacting the persons affected, as well as their families and loved ones,” said study author Natasha A. Grande de França. “An earlier and more accurate diagnosis can help to prolong the quality of life; however, the diagnosis of dementia is still plenty biased and hard to do. For this reason, we were interested in finding blood biomarkers that could be used to help clinicians in the diagnosis of dementia, especially Alzheimer’s disease (the most common dementia).”</p>
<p>To carry out the study, the researchers employed a cross-sectional design, utilizing baseline measurements from a larger ongoing study named COGFRAIL. This study involved 317 older adults, aged 70 and above, who exhibited mild cognitive impairment but not severe dementia. The participants were chosen based on specific cognitive scores and were either prefrail or frail, meaning they showed signs of physical decline but were not entirely dependent on others for daily living.</p>
<p>The study excluded individuals with severe psychological conditions or high dependency on others for basic activities. The final sample included a total of 177 individuals.</p>
<p>França and her colleagues employed several measures to gather data. They used positron emission tomography (PET) scans to measure the levels of amyloid-beta, a protein that forms clumps in the brains of people with Alzheimer’s, in various brain regions. Blood samples were also collected and analyzed for various nutrients, including different types of fatty acids, vitamins, and an amino acid called homocysteine. The analysis of fatty acids was particularly comprehensive, examining their composition in red blood cell membranes.</p>
<p>Over half of the participants (57.6%) were identified as having high amyloid-beta levels in their brains. The researchers found that higher concentrations of a fatty acid called clupanodonic acid were consistently associated with lower amyloid-beta load in the brain. This association was observed in almost all regions of the brain, except for the thalamus.</p>
<p>“I was expecting that if any association would be significant, that would arise from the fatty acids omega-3 EPA and DHA,” França told PsyPost. “However, a more consistent result was observed with a metabolite of EPA, the clupanodonic acid. This suggests we should expand the look and the research to less well-known fatty acids, in particular the metabolites of the EPA and DHA as potential more precise biomarkers.”</p>
<p>Furthermore, the study noted that linoleic acid showed a positive association with amyloid-beta load, while mead acid and adrenic acid were negatively associated, though less consistently than clupanodonic acid. Interestingly, the study did not find any significant associations between amyloid-beta load and blood vitamins or homocysteine, a common amino acid in the blood.</p>
<p>“Our study found potential blood biomarkers to be used in the diagnosis of dementias associated with the aggregation of amyloid-beta in the brain – a peptide associated with the development of Alzheimer’s disease,” França told PsyPost. “However, this is just the first step that needs to be confirmed with other studies in other populations.”</p><div class="addrop-wrap" data-id="64749"><p style="text-align: center;">

<p>Like all scientific research, this study comes with its limitations. The cross-sectional nature of the research means that it can’t definitively establish cause and effect. Additionally, the sample consisted of older adults who were either prefrail or frail, which may not represent the broader population.</p>
<p>“Our study has a cross-sectional design and was conducted with a very specific population (older adults with a light degree of cognitive impairment and who were at least pre-frail). So, some questions I can list include: has the association between clupanodonic acid and amyloid-beta happened by chance? Is this association true in populations in different conditions? What is the timing? – when does it start and when does it finish?” França explained.</p>
<p>The study, “<a href="https://academic.oup.com/biomedgerontology/article-abstract/79/1/glad248/7330065" target="_blank" rel="noopener">Associations Between Blood Nutritional Biomarkers and Cerebral Amyloid-β: Insights From the COGFRAIL Cohort Study</a>“, was authored by Natasha A.

Wow, that fucking sucks bro. I checked out the instance, and your name (and iconic profile pic) was on the top of whatever they call “All” over there.
If it takes off and you need to create a new name, please keep us informed. Your memes are vital lifeblood to the fediverse, lmao (but seriously everyone here loves you and we wanna keep in touch).
People have made distro recomendations already, so I want to talk a bit about what makes a distro a distro: application repositories and management, update cadence, and what’s installed by default. That’s pretty much it. Anything else can likely be transplanted from distro to distro.
Out of the default applications by far the most important is the desktop environment. Have a look at Gnome, KDE (and others, cinnamon, etc.). Pick something you like the look of. Gnome is known to be closer to Mac styling and sentiments, including the our-way-or-the-highway philosophy, limited customisability in the name of consistency, etc… KDE is the ‘we heard you like customisation so we put customisations on your customisations’ kind of environment.
Update cadence really boils down to one of two things - do you want a new OS version every few months where the distro maintainers manually release a bunch of software all tested together (e.g. Debian, Ubuntu, Fedora), or do you want each application released individually after it’s been tested to work with everything else (Arch)? Note that the former are sometimes called ‘stable’ releases but not because they are less likely to crash, but because there are simply fewer updates. The latter are called ‘rolling’ releases.
The application management philosophies are a lot harder to nail down, especially as a newbie. You will probably just have to accept that the first distro you try will likely not be the one you settle on. For instance I started with Ubuntu until I got fed up how difficult it was to install anything not found in the main repository (a surprising amount of software): In Debian-based distros (like Ubuntu) unofficial software is fragmented across thousands of ‘personal’ repositories that you must manually add URLs and signing keys for, it feels very clunky. Because they are personal respositories it’s easy for the owner to abandon it or just not push updates and you won’t even notice until it breaks after a system update. Once I had some Linux experience under my belt I found the Arch repository style much easier to work with: One central official repository, and one ‘unofficial’ repository. I’ve heard Fedora has a similar system.
But the single most important piece of advice - just pick something. The great thing about Linux is it makes hopping distros easy: A package manager makes it trivial to export a list of installed programs so you can reinstall them on your next distro. You won’t be enslaved to a distro once you decide, so just pick something and use it for a bit. Learn what you like and what you don’t. Use that to decide on your next pick.
From my previous comment, it looks like NHTSA is moving faster than I predicted. We’re now at step 1, with this Advance Notice of Proposed Rulemaking....
For the avoidance of doubt, for purposes of this Privacy Policy, “using” the Services includes being a Vehicle Occupant in a Connected Vehicle.
In section 2, “Information We Collect”, it says:
Identifiers - A real name, username or alias, postal address, unique personal identifier, online identifier, Internet Protocol address, email address, account name, Social Security number, driver’s license number, vehicle information (such as model and year), vehicle identification number (VIN), vehicle telemetry data, or other similar identifiers.
Other Personal Information subject to certain laws - A name, signature, Social Security number, address, telephone number, driver’s license or state identification card number. Some Personal Information included in this category may overlap with other categories.
Commercial information - Records of personal property, products or services purchased, obtained, or considered.
Internet or other similar network activity. - Browsing history, search history, information on a consumer’s interaction with a website, application, or advertisement.
Geolocation data. - Physical location and movements, including from Connected Vehicle Services or Technology Services.
Inferences drawn from other Personal Information. - Profile reflecting a person’s preferences, characteristics, predispositions, behavior, or attitudes.
Recordings - Audio recordings of Vehicle Occupants. Audio recordings when you call our call centers or a Retailer.
Payment information - Credit card information for optional Services, such as Subaru Starlink.
You can opt out of Subaru Starlink, but all that does is turn off the benefits the owner of the vehicle would get. It doesn’t disable the collection of information and recordings and such. (If you never paid for Subaru Starlink, this would probably prevent them from having your payment information, I guess.)
About your concern about kids, they have this to say:
Subaru’s Service is intended for a general audience and not directed at children under (13) years of age.
We do not knowingly gather Personal Information (as defined by the U.S. Children’s Privacy Protection Act, or “COPPA”) in a manner not permitted by COPPA. If a person under 13 submits Personal Information through any part of a Subaru Service, and we learn the person submitting the Personal Information is a child, we will attempt to delete this Personal Information as soon as possible. If you are a parent or guardian and you believe we have collected Personal Information from your child in a manner not permitted by law, contact us as set out in the “Contact Us” Section below. We will remove the data to the extent required by applicable laws.
So, basically, they’re going to collect until you call and tell them why it’s not legal. Until then, they’ll assume they’re not breaking any laws.
But then again, it’s entirely likely you don’t have a Subaru and don’t really care about Subaru specifically. If that’s the case, I highly recommend this page on Mozilla’s site where you can go to look more into most popular car brands’ privacy practices. Soiler alert: none of the 25 popular car brands they evaluated are much better than Subaru. And many are worse.
Whatever the case, it’s pretty clear that whether they’re “allowed to” or not, they do it.
And cars aren’t the only concern. Robot vacuum cleaners for instance are an issue. (Also, don’t believe a robot vacuum company when they say "this model doesn’t have a camera, it only has an “optical sensor.” If this interests you, see this talk.) And smart TVs. Just for instance.
