  • wow, no.

    none of what you said is actually true.

    • “gridlock” happens in non-grid layouts too, the english name is just taken from american road patterns.
    • “show me…” no. YOU made a claim (that local information suffices, which is a VERY bold claim), so it’s on you to prove that local information suffices.
    • roads are absolutely NOT “like wires”; they are like pipes. which is why civil engineers commonly use fluid dynamics to simulate traffic.
    • the rest of what you said is irrelevant to everything else.

    seriously, if you make a claim contradicting both the very premise of the post, and common knowledge on the topic, then at least provide a source for that claim, lr explain WHY you think your claim is true.

    “all the information is there” is not enough information to verify the claim; it’s a wild guess without evidence to back it up.

    if shit where THAT simple, we’d have it figured out 50 years ago… it’s almost like this isn’t the simple problem you desperately want it to be…




  • I’m extremely sceptical about local data being enough to properly guide traffic…

    the problem is that intersections are connected.

    one intersection influences others down the line, wether that is by keeping back too much traffic, thereby unnecessarily restricting flow, or by letting too much traffic flow, thus creating blockages.

    you need a big picture approach, and you need historical data to estimate flow on any given day.

    neither can be done with local data.

    could you (slightly) improve traffic by using local traffic flow to determine signals? probably, sure.

    but in large systems, on metropolitan scales, that will inevitably lead to unforseen consequences that will probably probe impossible to solve with local solutions or will need to be handles by hard coded rules (think something like “on friday this light needs to be green for 30 sec and red for 15 sec, from 8-17h, except on holidays”) which just introduces insane amounts of maintenance…

    source: i used to do analysis on factory shop-floor-planning, which involves simulation of mathematically identical problems.

    things like assembly of parts that are dependant on other parts, all of which have different assembly speeds and locations, thus travel times, throughout the process. it gets incredibly complex, incredibly quickly, but it’s a lot of fun to solve, despite being math heavy! one exercise we did at uni, was re-creating the master’s thesis of my professor, which was about finding the optimal locations for snow plow depots containing road salt for an entire province, so, yeah, traffic analysis is largely the same thing math-wise, with a bit of added complexity due to human behavior.

    i can say, with certainty, that the data of just the local situation at any given node is not sufficient to optimize the entire system.

    you are right about real-time data being important to account for things like construction. that is actually a problem, but has little to do with the local data approach you suggested and can’t be solved by that local data approach either… it’s actually (probably) easier to solve with the big data approach!






  • i have a privacy/security feature request:

    lock screen prompt when trying to switch profiles.

    currently all it takes to switch is two clicks, no identity verification.

    so if you have a regular and a NSFW (or otherwise private) profile, and you give someone your phone to look at a post, it’s easy to switch to a profile that should be gated behind a verification screen…

    infinity has this feature, and it’s really nice for peace of mind!

    otherwise voyager has been excellent all around! thanks for putting the work in!


  • that’s because they are forced to by the yt algorithm: you flat out cannot run a business on yt without resorting to clickbait titles, stupid thumbnails, and a bit of sensationalization, because the algorithm will deprioritize your video and unfairly limit your viewership if you don’t do those things.

    Steve’s videos are generally very much dry, factual reporting using fairly neutral language; or in other words: really decent reporting!

    if you want to complain about some tech youtuber doing the exact things you complain about, look at linus and jay…

    there’s some good reasons why steve is one of only a handful of tech channels i still subscribe to…



  • it’s about being able to read emotions:

    a large portion of autistic people have trouble reading emotions in others.

    that’s why they’re often drawn to things like books, comics, animated content, theater, and, like in this example, robots that clearly express their emotions.

    speaking for myself (diagnosed ASD), it’s the ambiguity that bothers me more than anything. i like it when things are nice and clear, neatly organized, and generally don’t require a lot of attention to interpret.

    interpreting the environment is taxing enough, adding a lot of emotional interpreting on top can quickly get overwhelming, which leads to poor mood, performance, and ultimately just straight-up headaches…again, this isn’t a hunch, it was part of the ASD diagnostic test.

    so i can imagine how much easier it is for kids with similar problems to relate emotionally to something that shows it’s emotions in clear, easily recognizable ways, rather than having to guess constantly. that constant guessing gets real tiring, real quick…






  • this is not true.

    it entirely depends on the specific application.

    there is no OS-level, standardized, dynamic allocation of RAM (definitely not on windows, i assume it’s the same for OSX).

    this is because most programming languages handle RAM allocation within the individual program, so the OS can’t allocate RAM however it wants.

    the OS could put processes to “sleep”, but that’s basically just the previously mentioned swap memory and leads to HD degradation and poor performance/hiccups, which is why it’s not used much…

    so, no.

    RAM is usually NOT dynamically allocated by the OS.

    it CAN be dynamically allocated by individual programs, IF they are written in a way that supports dynamic allocation of RAM, which some languages do well, others not so much…

    it’s certainly not universally true.

    also, what you describe when saying:

    Any modern OS will allocate RAM as necessary. If another application needs, it will allocate some to it.

    …is literally swap. that’s exactly what the previous user said.

    and swap is not the same as “allocating RAM when a program needs it”, instead it’s the OS going “oh shit! I’m out of RAM and need more NOW, or I’m going to crash! better be safe and steal some memory from disk!”

    what happens is:

    the OS runs out of RAM and needs more, so it marks a portion of the next best HD as swap-RAM and starts using that instead.

    HDs are not built for this use case, so whichever processes use the swap space become slooooooow and responsiveness suffers greatly.

    on top of that, memory of any kind is built for a certain amount of read/write operations. this is also considered the “lifespan” of a memory component.

    RAM is built for a LOT of (very fast) R/W operations.

    hard drives are NOT built for that.

    RAM has at least an order of magnitude more R/W ops going on than a hard drive, so when a computer uses swap excessively, instead of as very last resort as intended, it leads to a vastly shortened lifespan of the disk.

    for an example of a VERY stupid, VERY poor implementation of this behavior, look up the apple M1’s rapid SSD degradation.

    short summary:

    apple only put 8GB of RAM into the first gen M1’s, which made the OS use swap memory almost continuously, which wore out the hard drive MUCH faster than expected.

    …and since the HD is soldered onto the Mainboard, that completely bricks the device in about half a year/year, depending on usage.

    TL;DR: you’re categorically and objectively wrong about this. sorry :/

    hope you found this explanation helpful tho!


  • the DLC are pricey, but they’re also proper, old school expansions adding lots of content that actually enhances the game.

    it’s perfectly playable without the DLC, and there’s a LOT of DLC-sized mods on the workshop!

    kind of a fundamental problem with modern DLC: they generally don’t get cheaper over time (remember when that was an actual thing? not just sales, but actually lower prices for older games?).

    if you keep up with the releases it’s super okay at about 20/25€ once a year, maybe twice, bur if you’re late to the party it’s a whole lot of cash all at once!

    exactly why paradox introduced a subscription for Stellaris’ DLCs at 10€/month… honestly kinda worth it, if you know you’re just gonna play for a while and then move on…still wish stuff would just get cheaper at some point again…


  • and your source measured the effects of one single area that cathartic theory is supposed to apply to, not all of them.

    your source does in no way support the claim that the observed effects apply to anything other than aggressive behavior.

    i understand that the theory supposedly applies to other areas as well, but as you so helpfully pointed out: the theory doesn’t seem to hold up.

    so either A: the theory is wrong, and so the association between aggression and sexuality needs to be called into question also;

    or B: the theory isn’t wrong after all.

    you are now claiming that the theory is wrong, but at the same time, the theory is totally correct! (when it’s convenient to you, that is)

    so which is it now? is the theory correct? then your source must be wrong irrelevant.

    or is the theory wrong? then the claim of a link between sexuality and aggression is also without support, until you provide a source for that claim.

    you can’t have it both ways, but you’re sure trying to.
