  • Analogue likely doesn’t emulate the hardware at the transistor level, as it’s far more difficult than doing what most software emulators do.

    From an interesting (altough non-conclusive) HN-thread [1].

    Without seeing the code, it’s impossible to know where Analog’s implementation falls on the spectrum of software emulation vs hardware simulation. There is nothing magical about FPGAs that automatically makes anything developed with them a 1:1 representation of real hardware. In fact, there are plenty of instances where the FPGA version of a particular console is literally just a representation of a popular emulator only in verilog/vhdl. In many instances, even the best FPGA implementations of some systems are still only simulating system level behavior. Off the top of my head, one famously difficult case is audio, where many chips have analog circuitry that cannot be fully simulated.

  • I disagree with the notion that it’s better for the cheaters to have an easier time (and less chance of being detected), but you’re right, BattleEye doesn’t solve the cheating problem for GTA.

    Rockstar should fix their netcode and run game server on dedicated server, instead of their customers PC’s. I’d think decting aimbot isn’t the biggest issue, while cheaters are able to break entire lobbies…

    IMO no game should require client side anti cheat except for shooters, where looking through walls and aimbot is actually difficult to detect server side. At least for those is it possible to find valid arguments (except for being lazy).





  • I believe the advantage is that old drivers still work as they are all in the kernel. With them sharing much code it’s not even that big of a disk space issue. Edit: A more dynamic approach would be great though, especially with this size issue popping up.

    In a way it’s great that I’m able to replace any part of my system and it just works without me having to make sure the old GPU driver doesn’t leave some traces behind–altough while writing this the latter part shouldn’t be an issue with Windows auto download and installation of drivers.








  • I prefer swap files over swap partitions, because it makes it my partition layout simpler to manage.

    If your using a swap partition, make sure it’s located on an encrypted partition, else it exposes data stored in RAM (encryption keys etc). With SSD’s it’s difficult to make sure this data is actually deleted, even after overwriting.

    My preferred setup for a long time was LUKS with btrfs on top. Then subvolumes for /, /home and the swap file (+ /var/cache, /var/log etc.). This gives me peace of mind nothing is unencrypted except /boot.

    Nowadays I simply use zram, which allows for a small part of RAM to be compressed for swap. It’s great, simple to setup and performs well. Imo it should be default for all desktops.



  • Online transactions require a second factor which displays the actual amount to be transferred. This works by either an app which receives the transaction data (recipient, how much) over the network, or a device which takes the bank card and is used to scan something similar to a qr code. The device then displays the transaction data.

    This makes sure a fraudulent site can’t easily change the amount or the recipient of a transaction, even if they somehow made an identical website (or close enough).

    For remote transactions (e.g. online payments), the security requirements go even further, requiring a dynamic link to the amount of the transaction and the account of the payee, to further protect the user by minimising the risks in case of mistakes or fraudulent attacks.

    It’s not perfect, especially with people using a banking app and the second factor app on the same device for convenience sake.


  • That’s a bummer. Seems like Google Pixel and Fairphone are the only ones left. I don’t even know why manufacturers wouldn’t allow for relocking or even unlocking of their phones. I can’t imagine they make much money with user data and the phone is already paid for. Warranty claims shouldn’t be much of an issue either, as modifications can be easily detected and it’s likely not a relevant amount of people anyway.


  • The banking apps I’ve tried don’t require SafetyNet, instead they use Android AOSP’s basicIntegrity. The latter doesn’t require certification by Google, but also checks whether the device is rooted and the bootloader is locked.

    This means custom ROM’s on most devices won’t pass basicIntegrity, as only Google Pixel, OnePlus and Fairphone allow for relocking the bootloader.
