What is squashing?

Squashing is a process in which we squeeze multiple commits into one pretending it is only a single commit.

Basically squashing commits means we are rewriting the history of commits to make them look like single commit.

Why squashing commits is necessary?

Step 1 - Install and Configure dnscrypt-proxy

sudo su
pacman -S dnscrypt-proxy

cd /etc/dnscrypt-proxy/

Renew GPG key

Overview - Adding support for a new currency in Coinomi

The Coinomi wallet can support any kind of cryptographic currency because it adopts the model of a thin wallet.

A thin wallet will delegate most of the complexity to a trusted server, while still maintaining control of the private keys by using a deterministic key chain BIP44. It is different than SPV in that it doesn't need to perform any header or transaction merkle root validations (although it is optionally possible).

The advantage of a thin wallet is that it is light weight and can easily work with low-specs devices and consumes small amounts of network bandwidth. Some assets like Peercoin, CounterParty or Mastercoin can only work with this model because as SPV is not enough to validate transactions. The disadvantage is that it needs a trusted service to get the state of the network. A known attack for an SPV wallet is to hide transactions, in a thin wallet it is possible to al

Background

While I'm learning how to use Nginx, I was instructed to update the server_names_hash_bucket_size (/etc/nginx/nginx.conf) value from 32 to 64, but I don't understand why should I increase the value to 64.

How to squash commits in a GitHub pull request

o you've contributed some code to an open source project, say, Rails. And they'd like you to squash all of the commits in your pull request. But you're not a git wizard; how do you make this happen?

Normally, you'd do something like this. I'm assuming upstream is a git remote that is pointing at the official project repository, and that your changes are in your 'omgpull' branch:

	package com.mypackage.myapp.prefs

	import android.content.Context
	import com.mypackage.myapp.appCtx

	object MyPreferences : Preferences(name = "MyPrefsFileName") {

	var userWantsFancyUi by BoolPref(Keys.FANCY_UI, false)
	var isFcmTokenSent by BoolPref(Keys.FCM_TOKEN_SENT_TO_SERVER, false)
	var eggTapsCount by LongPref(Keys.EGG_TAPS_COUNT, 0L)
