  • 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.


  • 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.


  • 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.


  • Vibes

    They are for musicians but are fairly cheap, have a nice carry case which is very small, and let you hear what is happening without losing your shit. They are also easy to clean with hot soapy water and last so far multiple years of daily use. They don’t make you feel like you are underwater and more reduce volume than block sound, so walking around and talking to people is viable.


  • Hold their hairs that normally fall out in place until they are on camera then shed all at once.

    Make their eyes water whenever they are on camera by pushing just a little too much air at them.

    Wardrobe malfunctions are an option, but I think making them fumble everything would be better, so they try to hold a pen and it slips out of their hand etc.

    Make the camera drift upwards so they look shorter.




  • They may or may not be helpful, and trying both major types is a good idea to be sure, but the key is to self advocate with your psychiatrist. Some are reluctant to try the meds because “meds bad” but saying you would like to know if there are medications that can help you with emotional regulation, attention regulation, and sensory issues should lead to the offer of trying ADHD meds specifically.

    The first dose of Ritalin was a game changer because it gave me perspective. The things that I struggled with were actually harder for me than for other people, so I was not trying to do the same task and failing it, I was failing a harder task. That mindset shift allowed me to start the mental health work I am benefiting from today as well as start actually solving problems.

    I think addressing the Autism side of things will be easier with the ADHD side more supported.




  • Is this running with Vulkan? Have you tried using other graphics backends like DX or similar?

    Have you tried windowed mode? That had fixed a similar issue for me before.

    Have you tried running the graphics settings all down to as low as possible, like absolute potato mode, to see if it continues there? If it works as a potato then adding a few things until you replicate the issue will help you narrow it down. If it happens on potato mode then maybe try verifying the game files?

    Lastly, maybe consider trying an earlier driver version? Same for kernel? Sometimes weird issues like this are regressions and it was actually solved a few versions back but someone recreated the problem because they thought they were being smart and regressed the issue.


  • Dude, sounds like as really shitty time. I can see from your post history that you’ve had a bad run with communities (r/autism and their rule enforcement bullshit) and also a consistent theme of not having a very good home life. It sucks and being upset about it is the right first step. No problems there, this does suck, and you should at this point feel bad about it.

    That said, that is step one. Your emotions are telling you that things are not OK, so it is a good time to listen to them. That does not mean letting them make decisions though, just let them inform you about your needs.

    So next step, you need to know more about autism and ADHD. You will have this brain for the rest of your life and learning how best to use it now will pay off for your whole life. Learning that something is bad for you now means you can avoid it forever, rather than just trying to tank it and be OK with suffering it.

    I have read you have seen a psychiatrist. Have you had meds for ADHD yet? Did you try methylphenidate and dexamphetamine? Did you try other meds? I found that dexamphetamine did very little for me but methylphenidate did a lot, so I ended up on Concerta and additional Ritalin in the afternoon. Your experience may be very different to mine but trying a few things is a good idea.

    As for your parents, damn dude, having shitty parents is honestly awful. It is not your fault that they are shitty, that is a them problem. You need to take care of yourself and it seems likely that will mean getting out as soon as practical. Given that you are in the EU moving should be fairly easy, and given your English skills you should be able to function in a lot of different places. Maybe focussing on moving in a couple of years could make their bullshit a temporary inconvenience rather than the end of all things? Whatever they think is just their opinion, it is not fact, so if they treat you like shit they are not showing that you are shit, they are showing that they are the kind of people who treat others like shit. You can get out, it will take time, but it can be done.

    As for how to manage things now, I would recommend emotionally divesting from your parents. They say you are a junkie for smoking weed? Don’t fight it, just say OK, accept their opinion is their opinion, you don’t agree with them, you don’t need them to acknowledge that you are not a junkie, you can actually just let it go. You are the person who will decide on your values and make your choices. If they want you to be a certain way then they are welcome to be disappointed. You’ll live.

    There are some books which may be helpful but they are all in English, maybe there is one in Italian which is easier to really understand for you. First, have a look into parenting. Learn a little about attachment theory, parenting styles, and how good positive parenting is done. Once you actually know a little you can look at their behaviours and evaluate their performance. I would also recommend learning about narcissism, trauma, and cptsd.

    Given that you are young and don’t have decades of wealth acquisition behind you it will be challenging to move. Consider what you can do to earn some sort of income and develop your earning capacity. Obviously university is a great option depending on the field you are going into, but if it is not working out maybe look at whether you can finish up with a lesser qualification than a bachelor, say a diploma or advanced diploma. In many places this is basically equivalent to half or two thirds of a bachelor and allows you to finish more of your education later but enter industry now. That could shorten your path to financial independence significantly.

    Regardless of what you do, there are options. Some of them suck, some of them are risky, and most of them are hard, but you have survived however many years being undiagnosed and mistreated, you are strong enough for this. Reaching out to other people for help is a strong thing to do and with that reaching you can build a good life for yourself. Don’t sink into a depression because you can’t get out right now, focus on the path you can make out and make active steps in that direction. You can escape fascist Italy and you can make a life for yourself, meet cool people, have friends, have relationships, and do cool stuff, it will just take time and persistence.


  • Double speed audio.

    I have real difficulty with listening to people speaking slowly. By the time they finish the sentence I have lost the start, so unless I actively hold their sentence until it is done I often lose meaning or misunderstand.

    Listening at double speed allows me to keep up without losing what was said. I listen to audiobooks and podcasts while doing most chores and it has been a game changer.
