The History of Visa is Probably Different Than You Think

Visa credit card association founder Dee Hock is a world-leading expert in payment systems. While an official in 1968 at a local bank in Washington State franchised by Bank of America to issue BankAmericard, Hock became chairman on a committee to create what would become Visa in 1976. Hock is open-minded and outspoken. He has even spoken favorably of the online digital currency Bitcoin. “Bitcoin is one of the best examples of how a decentralized, peer-to-peer organization can solve problems that these dated organizations cannot,” Hock once said. “[Bitcoin] presents incredible opportunities for new levels of efficiency and transparency in […]

Updated Ethminer 0.9.41 Nvidia CUDA Version for Windows

Genoil, the developer of the Ethminer fork with Nvidia CUDA support (source) has been actively working and there have been some othere people contributing code, so we have compiled an up to date Windows binary of ethminer with CUDA support. Do note that this Windows binary release is compiled with VS2013 fo windows 64-bit and is for CUDA 6.5 as previous versions were compiled for CUDA 7.5, so there could be some performance differences between the different versions. The latest version comes with some optimizations that should increase a bit the performance when using the CUDA mode with the miner, however there are also some differences as you may need to manually specify the number of GPUs to use if you have multiple cards using the cuda-devices command line parameter if the miner fires only on one device. Additionally to get better performance you can try adding the following command line parameters to the ethminer:

For OpenCL: --cl-global-work 16384
For CUDA: --cuda-grid-size 8192 --cuda-block-size 128 --cuda-turbo

The Ethminer CUDA fork should work on Compute 2.0 or newer GPUs, but the performance on older GPUs can be worse, also don’t forget that you can run Ethminer in OpenCL mode as well on Nvidia-based video cards and not only on AMD if you are having trouble with the CUDA support or the hashrate you get is lower as compared to OpenCL.

– Download the updated Ethminer CUDA fork compiled for Windows and ready to be used…

As the use of MPESA has […]
