Free O'Reilly books and convenient script to just download them.

Thanks /u/FallenAege/ and /u/ShPavel/ from this Reddit post

How to use:

1. Take the download.sh file and put it into a directory where you want the files to be saved.
2. cd into the directory and make sure that it has executable permissions (chmod +x download.sh should do it)
3. Run ./download.sh and wee there it goes. Also if you do not want all the files, just simply comment the ones you do not want.

Smart Contracts on Cardano are Plutus scripts. We often talk about the size of transactions and blocks compared to the maximum currently authorized by the protocol parameters, but scripts are also limited in CPU and memory units.

Here is the description of those 3 properties from Cardano docs:

• The total on-chain transaction size in bytes: a simple transaction, for example, is around 300 bytes, one with metadata is around 650 bytes, and Plutus scripts are typically 4,000-8,000 bytes (future optimizations and improvements will reduce this).
• The number of computational (CPU) steps that the script uses: each step represents 1 picosecond of execution time on a benchmark machine. Typical scripts should consume less than 1,000,000,000 (1 millisecond).
• The number of memory units that the script uses: this represents the number of bytes that the script allocates. Typical scripts should consume less than 1,000,000 memory units (

After researching a lot on how to use PyTorch with a RTX 3060 card, specially with older versions or torch (0.4.0) and torchvision (0.2.1), I noticed that it was either impossible or very hard to do. RTX 3060 and these packages apparently doesn't have compatibility with the same versions of CUDA and cuDNN. I tried to do this by using different combinations with compiled versions available in conda, but didn't work, maybe it could work if you recompile from source these versions.

After all this, actually I was able to use RTX 3060 effectively with latest versions of all these dependencies with two methods:

1. Using a conda env, and latest versions published in pytorch site (https://pytorch.org/get-started/locally):

conda create -n rtx_3060 python=3.6.5
conda activate rtx_3060
conda install pytorch torchvision torchaudio cudatoolkit=11.1 -c pytorch -c nvidia
