    Someone told me that Oppa means ‘Uncle’, but in the particular district of Gangnam the word Oppa/Uncle also means Pimp.

    So it’s basically a song based on a pretty bad pun. I’ll protect you like an uncle, and by Uncle I mean Pimp.

    EDIT: English speakers likely would do better with the translation as 'Ill be like a Father to you, a real Las Vegas Pimp Daddy (where Daddy is a word that means Father but has more Pimp connotations, and Las Vegas being famous for legalized prostitution).

    It’s definitely debauchery. But we likely have memorials to Austin Powers and other such pop culture icons, so it’s understandable.




  • Discover seems to be the best bet to me so far.

    Discover is on the JCB, UnionPay, Troy and RuPay. (japan, China, turkey, and India respectively). Probably many more.

    Similarly, a JCB card should work wherever Discover is. It’s a billateral alliance.

    Oh, and all Discover cards work on Diners Club International because those two networks completely merged.

    Alliance members are not 100% acceptance. It seems like 95%+ acceptance though (most JCB will accept most Discover cards and vice versa, though you will get confused looks from the locals). It sounds like there’s a lot of old equipment around the countries that break compatibility but cities and other urban areas with new equipment shouldn’t have any problems.


    I’ll probably get a Discover card and start testing this out. I already have Visa and Mastercard but this new censorship issue seems serious enough to make me start supporting a 3rd place competitor.

    Between Discover vs AmEx, it seems like AmEx is about elite club / customer service / returns etc. etc. nice features but I’m not sure if it’s worth the price.

    Discover is free of annual fees, reasonable cash back, mediocre costs for the merchants (better than AmEx anyway and comparable vs Visa) and a surprisingly huge offering of international compatibility (RuPay, JCB, UnionPay, etc Etc). It seems like the winner to me as a 3rd card to experiment with.




  • Ummmm.

    ACH is how you get your paycheck, and it’s being updated to FedNow.

    Zelle is an independent network as well.

    And of course, there is Discover and AmEx.

    There is also cash, check, money order. They still work today, just people largely forgot how to use them.

    IIRC some Brazilian network was getting very popular off of this. If you want to look at non-US options.

    There are plenty of competitors to Visa/Mastercard/Paypal.





  • Wtf?

    • Premeditated Intent: Murder
    • Intent without premeditation. Heat of the moment: 2nd degree Murder
    • Doing something you weren’t supposed to and killing someone: involuntary homicide
    • Failing to do something you were supposed to and killing someone: negligent manslaughter.

    Who made this meme (and topic) and why is everyone so ignorant of the law? This almost certainly is vehicular manslaughter case or… If it can be suggested that it’s the pedestrian maybe was partially at fault it might be negligent manslaughter (ex: failed to stop when someone jumped out).


  • Real question: if we just parked our cars in the streets during these events and blocked the road, what could they do about it?

    Yes I get that my license plate is on there and that maybe I’ll get a ticket. But think about how many of those people actually have options beyond recording on their phones that is also nonviolent.

    Don’t drive aggressively into their cars or whatever but it shouldn’t be too hard to organize a blockade down the road a bit.


    One car is a hassle and needs a towing. 20 cars would be very difficult to remove. Of course it depends on territory (they might just drive off road and around) but consider your local geography and with some planning surely there’s a bottleneck that can be a real headache to them.



  • Great answer!!

    After thinking about all this for a while, I’ve gone with the basic binary tree (leaning towards AVL tree as I expect my use case to be read heavy).

    In my use case, multiple ‘intervals’ can merge together without major penalty (and should be merged together). It looks like a lot of these interval trees (including ph trees) are best when the intervals need to be kept separate.

    There is a part of my algorithm where ph trees might be useful though. I’ll have to give it some though.


    I’m kind of shocked that a basic binary tree ended up being so usable. Its a classic for a reason, lol. I guess I saw the intervals and got confused and overcomplicated things…


  • And typical RAM speeds are 100GB/second for CPUs and 500GB/second on GPUs, meaning 512MB operations are literally on the order of 5 miliseconds for CPU and 1ms on GPU.

    Below certain sizes, the ‘billions of intervals’ is larger than the damn Bitmask. Seriously, 8 bytes per interval (aka one pointer and 0 data) and that’s 8GB for the data structure.

    Instead of a billion 32-bit intervals to store (4GB of RAM at the minimum) it’s obviously a better move to store 500-million byte Bitmasks. And modern GPUs can crush that in parallel with like 3 lines of CUDA anyway.


  • Because CUDA and ROCm/HIP are far easier to program.

    The Khronos competitor to CUDA/ROCm is SYCL not OpenCL.


    SYCL vs these other options is a fun theoretical problem, but only Intel seems to be pushing SYCL at all. OpenCL got stuck in OCL1.2 (the 2.0 release was dead. 3.0+ OpenCL ignores OCL2.0 but it’s too late, OpenCL is seen as a dead end tech these days).

    The biggest issue is that OpenCL is a different language, while CUDA/HIP/SYCL are ‘just’ C++ extensions. This means that if you ever shared data between CPU and GPU in OpenCL (or DirectX or Vulkan for that matter), you have to carefully write and rewrite structs{} to line up between the two languages.

    Meanwhile, CUDA/HIP support passing structs, classes and more between CPU and GPU (subject to conditions of course. GPUs can’t do function pointers or vtables for example, but cpu-only classes can have vtables)



  • USA’s brand of capitalism has IP protections, such as patent, copyrights, and trademarks. None of which China actually follows.

    China is well known to conduct significant corporate espionage. (IE: hackers targeting corporations like Microsoft or Sony, not really people with “critical national secrets” but instead software they’d rather keep secret). China also hacks for national-security purposes too I’m sure.

    I mean, still better than the Russian hackers or North Korean ones that focus on randomware. China at least is trying to get economic benefits out of it, but… its clearly built up on a lot of stolen tech.
