  • 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.


  • 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.



  • 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.


  • It is more than that. In previous studies from the authors they have controlled for the nutritional content and the processing and found that the content itself, so carbs fats etc, have a certain amount of causal influence on health, but the processing also has a separate and significant effect. Just having less processing seems to have a meaningful effect. This means less of the additives like milk powder, xanthan gum, sweeteners, flavourings, extracts, and so on. The exact mechanism seems to vary depending on the specific case, but separating components of food and then remixing them as well as adding non food components and processing with heat and pressure seems to make these things no longer digestible and safe.


  • Nice, good to hear it worked out mostly. As for the black menu issue, consider looking at using various different libraries. For example, some games need the actual Windows .DLL files depending in exactly how they use them. The substitutes in WINE are just that, substitutes, so they have very slightly different behaviour in some cases. For GUI libraries if you get something wrong it is easy to have problems like a black menu box from something loading out of order, returning too fast or slow, or just being formatted differently. The native libraries can be used and that can sometimes solve the issue.


  • Yes, this can be done through WINE.

    Depending on your method of install for WINE you will use different specific buttons and so on, but the idea is the same. Take the patch .exe file and run it inside the same WINE prefix as the game is installed in. This can usually be done by opening Lutris and selecting the game, then clicking not in Run but on the WINE icon near it. That allows you to select the .exe file and run it in the same WINE prefix as your existing game install. From there the patch should be able to find the game at C:\Path\to\game and make the required changes.

    Hope that works out for you







  • OK so I can definitely see why it would seem pointless or really narrow, but I think this would have actually been very helpful for me and people like me. I have dyspraxia, a coordination disability. Mine is specifically graphomotor, meaning the exact types of movements involved in writing. My handwriting was absolutely terrible, causing pain in my hands (I also had incomplete hand dominance, so yay, both hands sucked equally), inability to express in a written form, and difficulty with tasks like painting, drawing, sewing, and cooking. Over the years the most helpful things were gaining strength and switching to printing only, no running writing at all.

    If this tool could help with increasing the feedback from my hands to my brain and also push my fingers through the shapes of letters I think I would have had some benefit. I think people who have had a stroke may also potentially benefit, though obviously it would need thorough testing.



  • I disagree. The current setup is like having the real estate have a key and you have a swipe card. The swipe card let’s you into parts of the house but you don’t have access to the basement or electrical box. If you wanted access to those you could ask but the real estate basically says no unless they really messed up, and even then they send a tradesperson to do the work and give them the key. If that tradespersons loses the key or gives it to someone else the real estate shrugs and says “What do you want us to do about it? Security is hard.”

    They also have a contract for all the furniture, most of which is bolted down, so you can’t even rearrange your house, let alone install a hand rail in the bathroom for your disabled brother who needs support getting in and out. You also can’t install anything on the walls like a TV or a picture frame, and attempting to do so would lead to the possibility of piercing a pipe or cutting a wire in the wall because you don’t have schematics.

    You can’t put a different OS on, you can’t modify the one you have, and breaking any of the protections on software is a violation of the DMCA, so you are a renter. You rent the device, they control the features, they decide what parts are available to the public (usually none), they decide when it will be end of life, and they make it very technically difficult to repair anything by using parts pairing. If they sold the device as a subscription with hardware upgrades included, repairs included, ongoing support included, then maybe locking it down would be OK, but otherwise no, it is unreasonable and I don’t think we really own our devices in a meaningful sense.

    This is simply incorrect. Implementing a lock on a bootloader is not dissimilar to a lock on your house. A person breaking in doesn’t care that they are breaking the law, they just need to find the how of breaking in. If I as a consumer want to enter my house or give a copy of my key to someone else as a backup I should be able to do so. If I want to leave my door unlocked I should have that right however foolhardy it is. And when it comes to locking the bootloader of a computer most people won’t notice it in general use but that isn’t the point. It is about the edge cases, the end of life for the device, the lack of security updates.
