Ask HN: What do you use to digitize your paper records?
13 points|narak|8 years ago|5 comments
I'm looking at digitizing most of my personal paper records like tax files, large value receipts, important letters, legal documents etc. The plan is to scan them to PDF or TIFF using a feed scanner. I want a solution that encrypts and backs up to the cloud. Anyone doing this? Suggestions for a good system and tools for this requested. Thanks!

Edit: So far I've found Cryptomator (https://cryptomator.org/) which seems like a good open source secure vault on top of my existing Dropbox/Google Drive storage.

I coded a Binance trading bot that analyses news sentiment and places trades

I had a lot of fun building this algo, and I'm quite happy with how it turned out.

Here's quick overview of what the bot does:

Pulls and analyzes the last headline from the top 100 crypto news sites

Provide an overview on the most mentioned coin across all the headlines

Analyse the sentiment of each headline and categorises the output by coin

Places a Buy order if the compound sentiment is positive and the a coin is mentioned in multiple headlines

It works with any cryptocurrency available on Binance

Here are some considerations that I am planning address in the future:

I accidentally used Feedspospot's top 100 Bitcoin feeds, so the sources are a bit biased right now

During my testing the compound sentiment wasn't high enough and wouldn't place a lot of trades

It can probably make use of multiprocessing to increase performance

Anyway, here is the GitHub repo for the source code: https://github.com/CyberPunkMetalHead/Binance-News-Sentiment-Bot

And if you want a step by step guide, I wrote one too:
