proot is just good enough to make you want to try it, but not good enough to keep using it. chroot was far better and if that's what was holding you back I'd recommending trying chroot.

I can relate to the clunk of having 3 different pieces to the setup, but I found myself using just the phone + keyboard pretty often for quick things. And since the desktop environment seems to sit in the background just fine, it wasn't much more than just turning on the phone and opening the keyboard. So in that sense it wasn't much different than a laptop.


I see - actually in my case I'm on Samsung, and Dex takes several seconds to boot. I like the desktop but It sounds like chroot + Termux:X11 would be way faster in every way.. I just really wish there was a Termux:Wayland - my favorite desktop doesn't seem to have an equivalent in X11 (niri, though maybe I need to look harder)


That's a great compliment; thank you.

As far as being outside, I imagine it's very dependent on personality. I often get restless and distracted working from home, and being outside or in a public space will help me feel a lot calmer and more focused. There's also a certain amount of intentionton it takes to "go to a specific place to do a specific thing" that helps me mentally.

It's not something I'm doing every day, but when the weather is beautiful and I'm feeling stuck behind a desk it's so nice to be able to work outside.


Do people ever think you are staring at them? You still have to point your face somewhere, just with a laptop screen it’s more likely obvious.


The focal plane of the glasses is around 10 feet, so I think you should be able to see it just as well as anything else at that distance.


Wow, there's some very nice builds there. I so far I hadn't seen anything that seemed genuinely pocket-able but there are a few there that look like they might work. I'd still really love something that can lock flat and be used on a lap, but that feels doable.


I love kbd.news and was recently struck by the novelty of the Tackle keyboard[0]. Seems rather extreme but my first thought was it could be a great complement to AR glasses. The design could be improved with improved with some tenting, because those keys at the edges will be easy to accidentally trigger when reaching for other keys towards the center.

Anyone - I need this! or something similar as a wearable keyboard. Please help me.

I rigged together a torso/chest mounted keyboard system using rugged keyboard and laptop chest harness modified. It actually kinda works but this Tackle keyboard would work really well for my use case, which overlaps significantly with this post.

I use Viture XR glasses, similar to the Xreals in the post. And I have a rugged laptop in a backpack with LTE modem and external antenna. Then what I do is go hiking in woods and periodically stop and open a Ta-Da chair, which I use as a walking stick or carry on my back, then put on the XR glasses which connected to laptop just using the Viture HDMI adapter, open the keyboard harness, and start working, all terminal based work.

The worst worst part of this crazy setup is the keyboard system. It’s awkward and kinda scares other people as it looks like maybe I have a tactical military vest on. opening it up and getting oriented is like 90% of the hassle.

Please someone help me get this Tackle keyboard. I don’t have the physical engineering skills needed, I’m a software guy. DM me on reddit with same username as HN. I will PAY decent money to anyone who can deliver me a working version of this Tackle keyboard.

I also own and tried tap strap and it’s not viable. Keys needed. LLMs combined with Voice to Text is promising and something on software side I’m looking into actively, but I don’t think no keyboard is a productivity retaining option anytime soon.

I do at least 10K steps daily when I have this system working and my goal is to get to 15K steps and drop weight. My preferred environment is outdoors away from desks and tables and civilization.



Unfortunately not but … but yes if you see me outside in my setup it bears resemblance.

The laptop harness closes so the keyboard is strapped to my chest while walking and there isn’t any screen as I use the Viture glasses as the monitor when I stop and work while sitting.


I could make people SO uncomfortable if I worked as a receptionist with this strapped on and threw in some very subtle signs of enjoying it. Reminds me of the south park nipple twisting guy. Very cool keyboard for VR and AR though. Can't really think of anything better if you wanted to type something quick in the middle of a physical VR game.


Hey thanks (I'm the author)! BTW the "Pro" version has the electrochromic dimming, so I recommend paying a little extra for that unless you're really sure you're not going to need it.

EDIT: To clarify, I meant the "Xreal Air 2 Pro", not the "Xreal One Pro". The latter are much more expensive.


Your price point for the used glasses is quite lucky to just play around with it or using it sometimes.

They cost 800 new :|

1080p is that really okay?


They are $299 on sale on the vendor website right now. I won't link because I don't want to promote them necessarily, but I think you must have seen a different vendor or something?


I also paid less than $300. OP must be referring to a different model.


Looks like they’re weirdly expensive through the EU store. Just navigate from xreal.com - I see them for $US 299


Have you looked on Amazon? I got the One (not pro) for less than £500.


That is absurd. Muscle mass is a huge predictor of mortality and anyone who isn't actively strength training and maintaining higher levels of muscle would see a health benefit by doing so. The idea that an overweight person has "too much muscle" is nonsense.

The side affect of muscle loss from these glp-1 agonist drugs is a serious downside that everyone should be aware of and try to mitigate if they choose to take them.


> The idea that an overweight person has "too much muscle" is nonsense.

I think you've misunderstood GP. He's not saying they have too much muscle when they're overweight. He's saying that take that exact same amount of muscle, subtract a ton of fat from their upper bodies, then they have "too much muscle" as typically needed for their body mass. I don't agree with their phrasing, but the point isn't "nonsense."


> then they have "too much muscle" as typically needed for their body mass

It's a leap to suggest that it's "good" to lose this muscle mass. If you're obese then it's good to lose fat. It's even better to do so while maintaining muscle mass.


Yeah, but whether you do resistance training while losing weight so that you have proportionally extra muscle mass than you had when you were overweight has nothing to do with the GLP-1 drug.

Every time GLP-1 drugs come up, the convo splinters off into topics that have nothing to do with anything unique to the drug. Now we're just talking about general weight loss and that it's good to exercise. Which is a trivial claim.


Yeah that's obviously better. They really meant it's "not bad" rather than "good".

When people read "muscle loss" they think "oh it's going to make me weak and feeble".


The problem is it is bad. People aren't just losing a proportional amount of muscle to fat mass to keep a good ratio - rapid weight loss is more catabolic towards lean body mass than it is with slower weight loss.

And most obese people are below optimal levels of total lean body mass overall even before this - their leg muscles being larger than an untrained person of the same height and an average weight does not mean that their leg muscles are of optimal size, much less the rest of their body.

Sarcopenia is a real risk for any obese person who is rapidly losing weight and GLP-1s are no exception.


Well, no, but I like how muscular I look (even with the extra weight). I wouldn't want to look skinny and lose the weight lifting gains.


I understand the point. Mine is that an ordinary untrained person will see health benefits and a statistically longer life from more muscle. An overweight person would have more muscle than their non-overweight counterparts (mostly localized to the legs, not upper body), and that is the one and only positive of being overweight. Willfully throwing that away will harm your health, full stop. The muscle loss problem with these drugs is talked about a lot because it is in fact a problem. Not because the medical field is mistaken in thinking it's a bad thing.


There’s negative cardiovascular effects from excess muscle just as with excess fat.

Normally that’s offset by the health effects of the exercise required to gain and maintain them as well as the lack of medical conditions that prevent exercise etc. But a fat person losing weight should inherently lose muscle mass long term assuming no changes to lifestyle.


This is one of those statements that is technically true but not particularly relevant. Obese people are almost never at a level of lean body mass that they would overall be at a good amount of muscle even for a healthy total weight, and rapid weight loss has consistently been shown in studies to reduce more lean body mass than slower weight loss.

Getting to the same level of additional weight from muscles as there is from fat is also incredibly difficult. The average 5'8 person not utilizing AAS would take years of dedicated training, dialed in diet and recovery, etc., to get to 200lb at 15% bodyfat. People get there much faster and much easier putting on fat.


What’s relevant is subjective. I’ll agree it’s far from as important as obesity, but the point is some of this adaptation is good.

As to loss of muscle mass from rapid weight loss, that’s very true but slightly overstated as regaining muscle can occur ~10x as fast as it takes to grow it in the first place. Someone without a significant calorie deficit barring nutritional deficiency or other impediment will regain whatever muscle mass is required for their lifestyle quite quickly. However, people don’t train with weighted vests as among other things it targets the wrong muscle groups.


>muscle mass is required for their lifestyle

The problem here is that the overwhelming majority of people that need GLP-1s have lifestyles that are not conducive to health and have less muscle mass than would be healthy to begin with.

Which is what has me so confounded by this claims - these people already have less muscle than they should for optimal health. Losing any is a significant issue. And without lifestyle intervention, they're not going to regain any of that lost muscle.

GLP-1 drugs are phenomenal and a huge win for health outcomes. But that doesn't mean we shouldn't be telling people the truth about their downsides and what they need to do to counteract them.


Let’s ignore GLP-1, and assume an individual slowly dieted to that exact same weight. What’s going to happen over the following year(s) is their lifestyle causes identical muscle loss.

In that context is this a long term downside of GLP-1 or their lifestyle?

Treating lean muscle mass as an inherent good makes sense when it’s adapted to a person’s current lifestyle. It doesn’t make sense when it’s a temporary situation.


False dichotomy - much of the muscle loss happens because of the rapid weight loss. If you diet more slowly and are not at very high levels of relative musculature you’re not going to lose nearly as much even in the long run, at least prior to advanced age. The newly skinny person might lose some muscle mass on their legs if they dieted down slowly, but it is significantly less likely that they will lose all of the other body-wide muscle mass that they do with rapid weight loss.

Your body will hold on to a surprising amount of muscle. Even people that take PEDs can drop back down to natural testosterone levels and keep ~80% of their gains in the long term. (Actual gains, not the temporary glycogen and intra-muscular water retention that you see with some compounds on cycle.) It takes significant effort for them, but they’re trying to hold on to supraphysiological levels, vs. someone who is trying to hold on to what is already on the lower end of the physiological range.


> False dichotomy

No, you’re looking at the short term effects on a largely irrelevant metric (volume) while ignoring the underlying mechanisms at play.

> Your body will hold on to a surprising amount of muscle.

It’s only surprising if you ignore what going on at the cellular level. Gaining fat or muscle eventually involves gaining new cells and structures like capillaries not just increased the volume of existing cells. This is a really slow process in muscle, but those new cells stick around and can rapidly adapt to stimulus as long as you have a sufficient diet.

So yes in rapid weight loss your individual muscles cells become smaller and less capable but that’s very quick to recover. Longer term, you’ll hit the exact same homeostasis point based on stimulus and long term diet.

PS: If this seems like voodoo magic it’s simply a very old evolutionary response to starvation that predates hominid development. Being able to fairly rapidly lower energy expenditure over say winter and then recover is a major advantage.


> Gaining fat or muscle eventually involves gaining new cells and structures like capillaries not just increased the volume of existing cells. This is a really slow process in muscle, but those new cells stick around and can rapidly adapt to stimulus as long as you have a sufficient diet.

It's an open question if hyperplasia even occurs in adult humans, and if so, under what conditions. MSC proliferation and differentiation is a thing, but none of this is actually particularly relevant to the discussion at hand.

> So yes in rapid weight loss your individual muscles cells become smaller and less capable but that’s very quick to recover. Longer term, you’ll hit the exact same homeostasis point based on stimulus and long term diet.

I'm not talking about hypothetical situations where people treat this more like a cut and then turn their lives around when it comes to resistance training and protein intake, because we know that in large part they don't. We know that a good portion of people on GLP-1 medications become sarcopenic and stay that way. And this whole thread basically started because someone was claiming that the muscle loss was good!

I'm not saying GLP-1s are bad or rapid weight loss is bad - I'm just saying you need to take steps to avoid muscle loss. And a huge amount of people on GLP-1s don't know about or understand these risks.


> I'm just saying you need to take steps to avoid muscle loss.

Do you have any evidence that long term lifestyle isn’t going to result in similar levels of strength?

> if hyperplasia even occurs in adult humans

It definitely occurs in other mammal muscle and some human tissue, and there’s studies supporting it occurring in human muscle. Myofibre splitting for example definitely occurs. https://pubmed.ncbi.nlm.nih.gov/16625366/

I’ll admit there’s controversy here, but I think the default position should be human biology is similar to other mammals unless someone demonstrates otherwise. Otherwise our unwillingness to preform experiments on humans and the expense of primate experimentation is going to create a scientific bias.


I was looking for this comment! Not a doctor, but as I understand it muscle is roughly equivalent to fat as far as your heart’s workload is concerned. I thought I also read that muscle movement helps with blood return.


Muscle movement is also necessary for the limbic system to function.


Limbic system is unrelated to muscle movement.

Movement is required for the lymphatic system to function, excess muscle volume doesn’t help.


Your complaint doesn't make sense to me. The negative health impact of being obese isn't equalized by having a little more muscle mass.

Also, if this is your stance, then GLP-1 is a red herring because you have the same issue with weight loss in general. Weight loss, without increasing resistance training, leads to muscle loss.


Yea what you're replying to is just pure fat-logic that isn't really backed by science. You will lose muscle from calorie restriction - that isn't really in doubt by anyone. However, when cutting weight, you can do a routine that maintains/builds muscle as you cut, to reduce the effect. A body with more lean muscle mass will be able to keep weight off for longer - this has been known, settled, and accepted in weight loss and fitness science for decades now. I've never heard anyone, anywhere posit that muscle loss is good - and would love to see a source, so I can laugh at it.

One insidious thing with these GLP1 drugs, is that they also seemingly affect muscles like the heart. I would not be willing to take one unless the risk of me carrying my weight far outweighed (no pun intended) the risk of the side effects. However, a lot of people seem to be treating it as some kind of miracle fad diet drug, which is concerning.

It also has other side effects like reduced elasticity on skin, etc. I suspect we'll see longer term issues in the next decade from these drugs, and I'm glad alternatives are being explored.


> Yea what you're replying to is just pure fat-logic

I can't even imagine what that's supposed to mean.

> However, when cutting weight, you can do a routine that maintains/builds muscle as you cut, to reduce the effect.

I literally talked about staying physically active.

The point is, you're going to have however much muscle your workouts and physical activity build/maintain. And you're going to lose whatever extra muscle isn't needed in your workouts. And that's fine, because you probably want well-balanced strength rather than legs that can carry around 300 lbs all day long.

None of this has anything to do with weight loss, except that simply walking around and daily movement becomes less of a workout as you lose weight because you're moving less mass. But it's not the weight loss directly that makes you lose muscle (assuming you're eating protein), it's the reduced physical strain because you weigh less so you're not needing those muscles. Do you get the distinction?

You don't need to work out even more to "reduce the effect" as you say. There's no effect. There's just working out to have whatever muscles you want. Weight loss will never lead to losing the level of muscle you need for your workout.


The reason you want to keep all your muscle on a cut is because that means a higher proportion of the weight that you do lose will be fat tissue.

This is the strictly superior outcome.


If you're "cutting" as part of bulking and cutting, then obviously.

But if you're going from obese to healthy, then your goal isn't to retain all your leg muscle, that's absurd. Your goal is to get to a healthy weight with overall balanced healthy muscle -- not disproportionately large legs.

Nothing is "strictly superior". What is best depends on what your goals are. Bodybuilding and not being obese any more involve wildly different measures of success.


If we didn't see tons of people reaching their "target weight" on GLP-1 drugs while having unhealthily low levels of lean body mass, you might have a point.

But that is what we do see. I'd argue that they're still in a better place than they were before, and we know that muscle that has been lost recently grows back very quickly when exposed to stimulus and adequate protein and rest, so I absolutely am a full believer in GLP-1 medications.

But if everyone on GLP-1 meds were keeping up with their protein and resistance training, even leg day, there would be very very few that had huge legs. That one portion of their body might be, on average, more muscular than a totally untrained individual, but it's not like being fat is the equivalent of a low bf% bodybuilder when it comes to lower body muscle mass. A formerly 300lb person dropping down to 180 with average genetics is almost certainly going to have smaller legs than someone who has been lifting for a year at the same height/weight.


No this is absurd.

The goal for anyone obese is to lose as much fat as sustainably possible.

For any given rate of weight loss, losing a higher proportion of body fat is always better.

This notion of "balanced" healthy muscle is one you've made up that no one else thinks of. I've been on fitness forums for well over a decade and have literally never seen a single case of this.


> The goal for anyone obese is to lose as much fat as sustainably possible.

Correct.

> For any given rate of weight loss, losing a higher proportion of body fat is always better.

That is in direct contradiction to your previous sentence. No, losing the higher absolute amount of body fat is better. While being sustainable healthy.

> I've been on fitness forums for well over a decade and have literally never seen a single case of this.

You may be on the wrong forums then. Most forums don't think all your days should be leg days.


> That is in direct contradiction to your previous sentence. No, losing the higher absolute amount of body fat is better. While being sustainable healthy.

This isn't in any way a contradiction if you're mathematically literate. If the highest rate of weight loss is some rate R, and losing weight without preserving muscle has you losing 0.5R muscle and 0.5R fat, losing R fat and 0 muscle is literally going to lose you more fat at the same rate. This is middle school math, and is literally what anyone who knows what they're talking about suggests, and is validated in the research.

> You may be on the wrong forums then. Most forums don't think all your days should be leg days.

Oh good more shit you've made up. No where did I suggest this. If you're going to engage in bad faith, go away.

Any well-rounded strength program will preserve muscle mass in a cut. You only need to work every muscle twice per week. No leg emphasis needed.


> if you're mathematically literate

No insults, please. I'm sure that if you have good arguments, you won't need to resort to that kind of attitude. And the fact that you're resorting to swearing later in your comment doesn't help you.

> If the highest rate of weight loss is some rate R

That's not a valid precondition. Nobody chooses a rate to lose weight at, and then magically chooses some proportion of fat vs muscle. What actually happens is that you lose fat through eating less calories, and you naturally lose muscle from using your leg muscles less by putting less weight on them, because you weigh less.

> No where did I suggest this.

You did. You literally said:

> This notion of "balanced" healthy muscle is one you've made up

You are arguing that one should preserve all of the leg muscle for a 300 lb body, even once you're 180 lbs. Again, that's absurd. That's going to take a far disproportionate amount of time at the gym on your legs to maintain. You say "No leg emphasis needed." That's completely and utterly false.

You are talking about bulking and cutting for strength training. But you already have a balanced body, I'm assuming. This conversation, on the other hand, is about obese people losing weight. Their muscles are disproportionately in their legs. Do you get that now? Do you understand the concept of a balanced distribution of muscle and strength, e.g. between arms and legs? Or since you're so concerned about having a conversation at a "middle school" level, do you need it explained in even simpler terms?


>you naturally lose muscle from using your leg muscles less by putting less weight on them, because you weigh less.

That is one cause of muscle loss, but there is a more important factor: when running a calorie deficit, the body removes protein from muscle so that it can turn the protein into glucose for energy. The human body preferentially gets fuel (calories to use to fight infections, digest food, and do the other things needed just to stay alive) from muscle (as opposed to getting it from fat) during times of not-enough-food because it takes more energy (fuel) to keep muscle cells alive than it takes to keep fat cells alive.

We evolved in an environment in which the body had no way to know whether the time of not-enough-food would last so long that it would lead to death. In that scenario, the policy that maximizes the probability of survival is to disassemble most of the muscles first and only then to start to disassemble the fat in the fat cells.

Corollary: most people on weight-loss diets should regularly exercise their muscles especially if they are elderly (because the elderly find it hard or impossible to regain the muscle once it is lost) and should consume a decent amount of protein.

Having a large amount of muscle mass doesn't make you live longer (as far as I know): the case for striving to preserve muscle mass during the aging process is that it gives a higher quality of life.


> No insults, please. I'm sure that if you have good arguments, you won't need to resort to that kind of attitude. And the fact that you're resorting to swearing later in your comment doesn't help you.

I have zero patience for intellectual dishonesty and made up claims as you've repeatedly done.

> That's not a valid precondition. Nobody chooses a rate to lose weight at, and then magically chooses some proportion of fat vs muscle. What actually happens is that you lose fat through eating less calories, and you naturally lose muscle from using your leg muscles less by putting less weight on them, because you weigh less.

Do you not know how thought experiments work? If you lose weight without strength training, you lose less fat and more muscle than if you lost weight while strength training. The numbers were chosen to illustrate that point, not to say those were precisely the numbers you'll see.

And of course it's entirely wrong that you lose muscle in your legs specifically because of the reduction in weight. You lose muscle everywhere you don't use it, which means a smaller proportion of your weight is lost as fat, which means it takes you longer to reach your target body composition.

> You are arguing that one should preserve all of the leg muscle for a 300 lb body, even once you're 180 lbs. Again, that's absurd. That's going to take a far disproportionate amount of time at the gym on your legs to maintain. You say "No leg emphasis needed." That's completely and utterly false.

This is yet more evidence of your complete ignorance of this topic and even what I've been suggesting. Your obsessive fear of having muscular legs blinds you to everything I've said.

Maintaining muscle mass takes far less work than building it. You literally only have to hit your muscles twice per week to do it, which could take anywhere as little as 1-3 hours per week of work if you know what you're doing.

You are objectively and empirically wrong about this and are only demonstrating how much you don't know about this topic.

> You are talking about bulking and cutting for strength training. But you already have a balanced body, I'm assuming. This conversation, on the other hand, is about obese people losing weight. Their muscles are disproportionately in their legs. Do you get that now? Do you understand the concept of a balanced distribution of muscle and strength, e.g. between arms and legs? Or since you're so concerned about having a conversation at a "middle school" level, do you need it explained in even simpler terms?

So much for no insults. Rules for thee and not for me seems like your motto.

If an obese person losing weight is worried about an imbalance, then the solution is not to let their legs atrophy to nothing but to increase the volume of the work for the muscles they fear are lagging so they can experience more growth and catch up, just like anyone else who has ever lifted weights.

These are extremely basic concepts in the field.

And lastly, a topic I should have mentioned earlier, anyone who follows your advice, which is clearly the advice of someone who neither knows what they're talking about nor the advice of someone with a healthy relationship with body image, will inevitably be increasing the risk and extent of lose skin if they avoid strength training. If you don't bother preserving muscle, not only will it take longer to reach your target body composition, you will have end up with less total tissue filling your skin and, short of surgery, you would have to build muscle to fill it up again to reduce or resolve the issue.

Your advice is objectively terrible, rooted in ignorance of basic fundamentals of the space, and will lead people to worse outcomes.

You should in no way be offering advice on this topic to anyone. You will only increase the chances that they give up as their journey takes longer and results in worse outcomes in terms of both health and aesthetics.


> I can't even imagine what that's supposed to mean.

Where are you getting your information from?


Don't you also need a bigger heart when you gain weight and not need as big of one at less weight? Liposuction and amputations can also result in muscle loss in the heart from it having less work to do.


You don't want to have too much hypertrophy in the heart for sure. My understanding though is that it's very hard (almost impossible?) for it to be a problem without exogenous hormones, or some other condition that allows you to accrue an abnormal amount of muscle mass (e.g. myostatin defficiency).

Edit: I mean someone with a healthy fat percentage body composition. Of course having to pump blood to a 300lb-140kg body is problematic for the heart, be it a mostly fat or mostly muscle body composition. My point is it's just much easier to be fat enough for it to be a problem than muscular enough without exogenous hormones or an abnormal condition.


Yeah, LVH is the big deal there in both cases.

Telmisartan, an ARB generally used for BP management, can actually reverse LVH to a significant degree over time, though. Popular for bodybuilders on large quantities of AAS for that reason.


> One insidious thing with these GLP1 drugs, is that they also seemingly affect muscles like the heart.

Okay so I don't know where I picked this up - it was a decade or more ago - but I always thought the problem was losing weight too fast is what causes bad muscle loss such as from the heart, or from leg/other muscles beyond what's no longer needed from the weight loss. Something like, you're starving yourself so your body starts drawing energy not just from your fat but from anywhere it can.


The idea that people on GLP-1s shouldn't be trying to preserve (or indeed build) as much muscle mass as they can is absurd. It is more important than ever to perform resistance training and make sure you are getting adequate protein.

But this isn't anything special about GLP-1s - the same is true for any sort of rapid weight loss approach, be it diet, GLP-1, lap band, whatever.

And we see improved cardiovascular outcomes independent of weight loss for people on GLP-1 drugs in widespread clinical trials, vs. one mechanistic in vitro study showing loss of heart muscle cells.


There is a huge conflation of cause and effect with respect to muscle mass and longevity.

Low muscle mass is associated a broad swath of illnesses, low activity, and generally poor health.

Muscle mass's power as a predictor is not the same as it's utility as an intervention.


As long as you're not using exogenous hormones, muscle mass can only be achieved with exercise that builds or preserves muscle. I'd say that's a pretty good predictor against frailty, which is strongly associated with mortality among the elderly.


True, but frailty in the old age has a reason that cannot fully be mitigated with exercise: depletion of stem cells. The same mechanism will make our blood vessels thin and prone to bursting etc.


Exactly my point! you have a chain of 3 associations right there. One is nearly tautological and another has backwards causality. Correlation =/= causation.

Something being a good a good predicative indicator does not mean it is an effective intervention.


There is no backwards causality in the implication that building or preserving muscle that would otherwise be lost can prevent or delay frailty, nor is it backwards to imply that frailty can lead to death (from falls, disease, etc.). I really don't understand what you're trying to say.


"Muscle" isn't an intervention.

"Building muscle" is an intervention and has extremely well-documented mechanisms that have a causal role in improving health.


Muscle actually is an intervention for one of the biggest risk factors in metabolic syndrome - insulin resistance.

Muscles use glycogen. They use more glycogen when you're doing the sort of thing that builds muscle, so of course it's even better there, but someone who just genetically puts on more muscle at the same level of activity as someone who puts on less will still use more blood sugar for their muscles, and thus be less likely to increase their insulin resistance.


Ok how do you "intervene" with muscle? Do you surgically transplant it?

It's a thing that exists. Genetic differences are not interventions. Those are also simply things that exist.

An intervention is a change in treatment or behavior that induces a change with effects we want.

Differences between individuals are not interventions.

The intervention of interest is building muscle through strength training.


There's a significant number of posts in this larger thread saying that it is basically just the benefits of exercise that is providing the positive health outcome and not just having the muscle, and I interpreted intervention in a broader manner based on that context.

My point is simply that muscle in and of itself has positive benefits, even if you didn't need to do another healthy activity to maintain or gain it.


"The idea that an overweight person has "too much muscle" is nonsense."

Our bodies like to have a balance of everything.

"Muscle mass is a huge predictor of mortality"

In biology, most such predictors work only up to a point. Massively muscular people don't live to be 120. Bodies don't work in a straightforward fashion, and there are other effects to consider. For example, activation of the mTOR pathway, associated with tissue growth, is associated with shorter lifespan, and mTOR inhibitors like rapamycin seem to be modestly prolonging lives of many species.


lol image creating a beloved tech product, growing the company to the point where it gets acquired by a tech giant, and then waiting until they spit it back out so you can start it all again.

Congrats to Eric. This whole thing is so funny to me and I can't wait for my new Pebble.


Patience is a virtue :)


I get major lag spikes when the gpu is under heavy load (like doing Stable Diffusion inference or something). TBF I haven't A/B tested with X11, but I don't ever remember it being like that. An extra frame of latency isn't great on it's own, but the occasional spikes in lag are really irritating.


May still happen especially if it is thrashing vram in and out of system memory or something, but have you tried lowering priority of the stable diffusion process?


I can also attest to horrific lagspikes on an Optimus laptop even if Intel is driving the desktop. Memory pressure is definitely the problem here. Lagspikes actually lessened when I switched to Wayland Gnome. I think they lessened further with PREEMPT_RT on kernel 6.12. Nvidia requires an environment variable to build on real time kernels but it plays surprisingly nice as of driver 570. But if you have this config, you need at least 11th gen Intel iGPU or AMD APU, because i915 does not build for real-time kernels. Only the Xe driver works and only if you force_probe the ID if it's Tiger Lake.

...Which I don't get because the Xe driver is said to explicitly support, at minimum, Tiger Lake. I played Minecraft on the iGPU with Xe and it was perfectly fine. It... drew 3D graphics at expected framerates.


Showing up early just makes other people feel like they did something wrong by showing up on time.


It could be argued that people can’t be made to feel anything, apart from pain. How people react, on the other hand, may be quite different.


True. Probably wouldn't be a very good argument though.


Other people's feelings about a dimension don't change the dimension.


In a social context, almost everything some people do changes how other people feel.


I bought my 65" TV for $299 recently, including shipping to my doorstep. Clearly all the bullshit that's baked into it is subsidizing the price by a lot.

I just never gave it network access and I use it like a dumb TV with a streaming box, so I get to benefit from a price subsidized by the the other 98% of the population who are getting exploited. The whole thing is kinda gross.

It's like there's this enshittification tipping point that you can't come back from. Realistically, who is going to buy a dumb TV at a much higher cost? People who are already savvy enough to get around a smart TV? People who aren't? I don't see it working.


I worry about how long it'll be before the manufacturers either make the TV demand an internet connection, or simply build one right into it.

Exactly, that's why all this "I want a dumb TV!" stuff is, well, dumb.

It doesn't cost any less for a mfgr to make a dumb TV, in fact it would cost more. Modern TVs need a lot of computing power to make them work properly, so making the thing connect to the internet and show you ads really costs them nothing for hardware. Then they get to subsidize the TV with all the ad revenue, the kickbacks from the various streaming apps pre-installed, etc. A dumb TV would end up having the exact same hardware and a higher price tag. What kind of idiot would buy that? Not enough to make it worthwhile for the mfgr. If you don't want ads, just don't connect the TV to the internet.

It's a lot like modern Windows laptops that are cheaper than the same laptop with Linux pre-installed. MS and/or the laptop mfgr get a bunch of kickbacks from the crapware vendors to pre-install their crapware, so you end up paying less than you would for having the mfgr pre-install Linux (a free OS).
