Host Your Site Under Your Domain on IPFS

Host Your Site Under Your Domain on IPFS

This is a step-by-step tutorial for hosting your website under your domain on IPFS, from zero, on a DigitalOcean Ubuntu 16.04.3 x64 Droplet (i am using the $10 variant with 2GB RAM).

Install IPFS

Log in as root.

First, make sure the system is up to date, and install tar and wget:

def club_similar_keywords(emb_mat, sim_score=0.9):
"""
:param emb_mat: matrix having vectors with words as index
:param sim_score: 0.9 by default
:return: returns list of unique words from index after combining words which has similarity score of more than
0.9
"""
if len(emb_mat) == 0:
return 'NA'
xx = cosine_similarity(emb_mat)

How To Work With Multiple Github Accounts on your PC

How To Work With Multiple Github Accounts on a single Machine

Let suppose I have two github accounts, https://github.com/rahul-office and https://github.com/rahul-personal. Now i want to setup my mac to easily talk to both the github accounts.

NOTE: This logic can be extended to more than two accounts also. :)

The setup can be done in 5 easy steps:

Steps:

  • Step 1 : Create SSH keys for all accounts
  • Step 2 : Add SSH keys to SSH Agent

Using Whisper to transcribe audio

This episode of Recsperts was transcribed with Whisper from OpenAI, an open-source neural net trained on almost 700 hours of audio. The model includes an encoder-decoder architecture by tokenizing audio into 30-second chunks, normalizing audio samples to the log-Mel scale, and passing the data into an encoder. A decoder is trained to predict the captioned text matching the encoder, and the model includes transcription, as well as timestamp-aligned transcription, and multilingual translation.

The transcription process outputs a single string file, so it's up to the end-user to parse out individual speakers, or run the model [through a sec

Notes on the GPT-4 abbreviations tweet

Notes on this tweet.

  • The screenshots were taken on different sessions.

  • The entire sessions are included on the screenshots.

  • I lost the original prompts, so I had to reconstruct them, and still managed to reproduce.

  • The "compressed" version is actually longer! Emojis and abbreviations use more tokens than common words.
