Create Root Key

Attention: this is the key used to sign the certificate requests, anyone holding this can sign certificates on your behalf. So keep it in a safe place!

Install drivers (firmware) for debian 8 (jessie) on GA-H170N-WIFI with Nvidia GTX970

After installing debian 8 (jessie) on my GA-H170N-WIFI with Nvidia GTX970, there are many hardwares not working properly. After digging for some time, I finally get everything working. So I am going to write this simple note to help people might need this in the future (for me as well).

Today is 2016/6/25, many things may be fixed in the future

Things not working properly after installation:

Configure Git to use a proxy

In Brief

You may need to configure a proxy server if you're having trouble cloning or fetching from a remote repository or getting an error like unable to access '...' Couldn't resolve host '...'.

Consider something like:

iOS Cell Registration & Reusing with Swift Protocol Extensions and Generics

A common task when developing iOS apps is to register custom cell subclasses for both UITableView and UICollectionView. Well, that is if you don’t use Storyboards, of course.

Both UITableView and UICollectionView offer a similar API to register custom cell classes:

public func registerClass(cellClass: AnyClass?, forCellWithReuseIdentifier identifier: String)
public func registerNib(nib: UINib?, forCellWithReuseIdentifier identifier: String)

	# This is a helper script that keeps snapraid parity info in sync with
	# your data and optionally verifies the parity info. Here's how it works:
	# 1) It first calls diff to figure out if the parity info is out of sync.
	# 2) If parity info is out of sync, AND the number of deleted files exceed
	# X (configurable), it triggers an alert email and stops. (In case of
	# accidental deletions, you have the opportunity to recover them from
	# the existing parity info)
	# 3) If partiy info is out of sync, AND the number of deleted files exceed X
