How does async work in async-std?

(Phaiax - 2019/12/1 - CC_BY_SA 4.0)

Lately I was porting a software from tokio/futures-1.0 to async-await. I somehow thought async-std was the successor of tokio and ported everything to async-std. 80% in, I noticed that my hyper dependency requires tokio and that it's not possible to replace tokio with async-std without also replacing hyper. Also, tokio and async-std try to solve the same problem. So I started a journey into the inners of the rust async story to find out if it is possible to use both tokio and async-std at the same time. (tl;dr: it is). I had heard of reactors and executors before, but there was much new stuff to discover.

This is a little challenge to find out which tools programmers use to get their everyday tasks done quickly.

You got your hands on some data that was leaked from a social network and you want to help the poor people.

Luckily you know a government service to automatically block a list of credit cards.

The service is a little old school though and you have to upload a CSV file in the exact format. The upload fails if the CSV file contains invalid data.

The CSV files should have two columns, Name and Credit Card. Also, it must be named after the following pattern:

YYYYMMDD.csv.

How to change Pantheon Terminal's color scheme

Many of us spend many hours of our days using their terminal. Plus, we all have different tastes when it comes to color schemes. That's why the ability to change the color scheme of a terminal is one of its more important featuresl. Throughout this tutorial, I'll teach you how you can change the looks of your terminal, step by step.

This tutorial is aimed at elementary OS users, but it also works for any Ubuntu user. Start by installing dconf-tools:

sudo apt-get install dconf-tools

Secondly, you need to decide which theme you're going to apply. You can find dozens of terminal color schemes online, you can even design your own using this web application. Design the color scheme, hit "Get Scheme" and choose "Terminator". You'll get a raw text file with a background color, a foreground color and a palette. Those strings define your color scheme. In this tutorial, I'll post an

Password value object for MongoMapper documents
# In a MongoMapper::Document,
# simply add
# key :password, Password
# your password will be automatically hashed,
# and you can compare plain-text passwords with the user's hashed password, ruby style:
# User.first.password == '1234'
# => true
#
# Also, prevents passwords from being leaked onto the console or error messages:
# User.first.password
