  • Once again we hit the wondrous conflation of correlation and causation.

    Grip strength is not something that you can train to have an outsized impact on your health. It is a good marker because it is not something people often train, it is something that an active life will naturally train, and it tends to be a part of most upper body exercises.

    It would be like saying people who carry lots of cash live longer, so you should carry lots of cash. People who are richer have less worry about carrying cash and it is a good indicator they are not running all the way out of money each week. Taking money with you won’t make you rich and it won’t change whether you can afford good healthcare, food, housing, or a lower stress life. Impacting how much cash you carry won’t make you live longer, but measuring it across the population is a simple proxy for wealth and therefore health.

    Come on The Guardian. Get a science reporter who cab actually do their job, someone who has at least a bachelor of science and ideally took some critical thinking units.


  • Yeah, it is a fairly large dataset depending on the tower location. For example, in an inner city locale you may have hundreds of devices on a single passenger train going past a local tower. These transient handsets used to cause a massive issue with drop outs and loss of signal as they would acquire and then drop service from a given tower. Nowadays we have solutions for this which centre around shaped beams along the direction of travel with communication between towers to ignore handsets which are moving along a travel corridor.

    To make that clearer, imagine the overhead train line has passengers moving along and under the train line people are walking on the street. The various towers which are along the train line will pass information about which handsets are moving and which are local so the local towers can handle local handsets and specific towers above can handle the train customers. This keeps the lower towers from changing their directionality and dropping calls and data confections, but also allows the train handsets to have reasonable connection to the network.

    Another interesting case is what used to happen at the edge of the range for a tower. The whole tower could modulate its power so it could reach a far off handset if nobody else was around, extending the effective range. This unfortunately meant that if someone came closer to the tower it would have to lower its power to not harm the handset and the person far away would lose signal.

    Nowadays the power level can be handled per handset. Each handset gets a small portion of a second, actually a small handful of parts of a second, and the power of the tower is adjusted to reach them at their required level for their time slots. If someone comes online close to the tower you may have competition for the time of the tower and thus lower speeds but the power will still match your handset independently of the rest. Very cool technology, way better than what it was with GSM, and also much more secure.


  • Yeah, it is absolutely insane to think that as a person with a literal disability in attentional regulation I have had fewer collisions than most people who are not disabled. It seems like if it is too easy people stop trying and don’t take it seriously, so they text or change the music or reach over the back. I know I can’t do that without risking a major issue and I actively have to maintain focus, so I simply do not ever “let it slide” or “just this once”. Rules can save lives if followed, but do nothing if ignored.



  • Put simply the radio broadcasts a sort of hello message to the tower so the tower knows where to listen (this is about signal direction or beam shaping, but imagine the eye of Sauron swiveling to see Frodo). This includes the identifier of the handset, the IMEI number, so that the tower can keep track of who is who. The second step of getting connected to the network is done with the details inside the SIM card, specifically the IMSI number.

    If your phone has no SIM card you can still make an emergency call. You can also have an eSIM which is a software version of the SIM card. In both cases you can bypass the SIM and get connected.

    If you turn airplane mode on the radio is powered off in theory, but this is not absolutely guaranteed. It should be off, the system will report it is off, but there are fringe cases where it may still be very slightly active, usually from malware or similar things.

    So no SIM means no IMSI, but the radio itself has the IMEI and that handset is hard coded to that identifier. If the radio powers on it will broadcast the IMEI to negotiate connection with or without the SIM and IMSI.


  • It isn’t really clear from what you have said if you are using a laptop or desktop. If you are using a laptop chances are you only have one primary storage medium, likely an HDD or SSD. If it is a desktop it is more likely you have or can have two drives. If you have the option of having two entirely separate drives you can keep Windows installed on one drive and Linux on the other. You could select your boot device on startup and the chance of one messing with the other is reduced a lot.

    A potentially better way to learn is to either install linux on an old or spare machine or to just boot off a live USB. The great thing with a live USB is you can access the system, use the software management stuff, try out finding settings and getting things done, all while being able to just reboot and have everything go back to normal after. If you want you can even make the USB a persistent install, so changes hang around and allow you to keep using the system in Linux with your changes over multiple reboots.

    That all said, my honest recommendation is to use VirtualBox or a similar program. VirtualBox lets you run a virtual machine and install Linux on it without risking anything on your main system. You can learn how to do software updates, install new programs, configure things, and so on all while touching nothing on your system. Your machine can keep working as normal in Windows, you can learn with no risk, and you can compare different versions of Linux to see what you prefer. The process for setting up a virtual machine in VirtualBox is fairly simple and should only take about half an hour to do, so it isn’t a big time investment.


  • The unfortunate thing about people is we acclimatise quickly to the demands of our situation. If everything seems OK, the car seems to be driving itself, we start to pay less attention. Fighting that impulse is extremely hard.

    A good example is ADHD. I have severe ADHD so I take meds to manage it. If I am driving an automatic car on cruise control I find it very difficult to maintain long term high intensity concentration. The solution for me is to drive a manual. The constant involvement of maintaining speed, revs, gear ratio, and so on mean I can pay attention much easier. Add to that thinking about hypermiling and defensive driving and I have become a very safe driver, putting about 25-30 thousand kms on my car each year for over a decade without so much as a fender bender. In an automatic I was always tense, forcing focus on the road, and honestly it hurt my neck and shoulders because of the tension. In my zippy little manual I have no trouble driving at all.

    So imagine that but up to an even higher level. Someone is supervising a car which handles most situations well enough to make you feel like a passenger. They will switch off and stop paying attention eventually. At that point it is on them, not the car itself being unfit. I want self driving to be a reality but right now it is not. We can do all sorts of driver assist stuff but not full self driving.



  • No good options I have found, but I would love to see the result of this thread. I use both IEMs and Bluetooth headphones depending on the circumstance and the good thing about having both is you aren’t stuck with one or the other.

    The other question is whether you want things like audio playback speed, chaptering for audiobooks, and marking as read. For someone using this for podcasts or audiobooks those would be useful features, but if it is exclusively music then it won’t make a difference.


  • Essentially correct. Roblox has a sort of central platform, the basic stuff which determines how interacting works, how things can look, what defines objects etc, and then it has things that run on top of that, so specific games with rules, different experiences within that base platform.

    For example, you may want to play a spiderman kind of webslinging game. The rules for shooting your web and attaching to buildings along with how swinging works are all handled by the custom code, but the core of how the game looks, multiplayer conections, state saving, and so on are all handled by the outer game logic.

    So all these people dressing as ice agents may be running around in other peoples games and using in game capabilities to block them from moving, to harass them, and to grief them. The other players can ban the ICE agent players from their game but is is exhausting and the disruption is real.

    The more shared spaces, the large public rooms, is where you would do something like protest. You could take all the players who are griefing with ICE outfits and make it clear they are not welcome, unpopular, and just plain annoying. It may or may not work, but it is good the kids are not just accepting it and moving on. The kids are all right.



  • Yeah, exactly, like the idea of Mensa is there but she is shown in a more TV friendly way without completely wiping out what makes her Mensa. Also, the relationship drama from the single perspective of Murderbot is uninteresting, even a little gross, so it is described from a distance. They did not have the internal monologue stuff in the show so they did a lot more showing rather than telling. That makes it much more detailed and clear compared to the distant vantage of Murderbot describing “a sexual relationship”. Different, not worse, not better, but different. Honestly I am surprised how different it is without putting me off.


  • I feel like the changes to characters are really large. The feelings I have from each character in the books and the show are not close enough to be the same character. Mensa is so much more emotional and reactive in the show than she was in the books, but I like both. Murderbot is much more human than in the books, there is way less internal monologue, so it feels very different, but I still love the character in both. Same for all the rest.

    As for the story changes, so far it seems good in terms of changing just enough to make it fit for TV rather than doing something insanely different with only a passing resemblance to the books. I like how the violence is shocking, sudden, and really limited. In the books it is not the whole story, one gory moment after another, and I was worried they would get sucked into the trap of violence being attention getting and shocking and therefore needed in huge quantity.

    The visuals are excellent. From a purely technical perspective they have done a great job with making something easy to look at, enjoyable to experience, and mostly visually consistent. There have been very few moments where the colour balance is skewed weirdly, where the lighting requires adjusting the screen, or where the volume levelling was terrible. Great production quality.


  • I have a HP EliteDesk 800 G3 as a server at home. It is small enough to fit on my printer stand, it has two 4Tb HDDs for data in raid 1 and one 256Gb SSH for the OS and VMs to run from. It has 32GB of RAM and works really well. I have a few VMs for managing media, one for my personal jabber server (Open fire), another for calendar and contact sync, and Syncthing. I also have another 16GB of RAM unallocated so far which makes me itch for another VM to spin up, but so far I haven’t had something come to mind service wise. Because it is all off my main system I can do updates, change my HDD, take my machine with me, and I always know my server is OK. The same goes in reverse, I won’t bork my main system when doing server stuff. It is very handy and I find it useful to segregate things, but your situation obviously could demand a different approach. That said, I would recommend it instead of upgrading just because of the stability and segregation of risk.



  • I think when someone is making a movie or TV show they don’t want to have anything that distracts from the story, so they only show clean lines, clear surfaces, and new enough items that their disrepair or dirtiness is not taking away from the story.

    My experience was pretty poor compared to my peers, but I was actually homeless for a period so I think I was legitimately below the standard of the time. That said, rich people pay cleaners to make their house look good. They have good storage solutions, new items, and throw away and replace anything that looks bad.
