Problem

I have two Github accounts: oanhnn (personal) and superman (for work). I want to use both accounts on same computer (without typing password everytime, when doing git push or pull).

Solution

Use ssh keys and define host aliases in ssh config file (each alias for an account).

How to?

1. Generate ssh key pairs for accounts and add them to GitHub accounts.

Even tho Unity has implemented a game-center api (Social api) it doesn't have a way to generate a verification signature, which you need to use game-center as a authentication method.

Luckily the objective-c code required is pretty straight forward. (Apple documentation: generateIdentityVerificationSignature)

#import <Foundation/Foundation.h>
#import <GameKit/GameKit.h>

typedef void (*IdentityVerificationSignatureCallback)(const char * publicKeyUrl, const char * signature, int signatureLength, const char * salt, int saltLength, const uint64_t timestamp, const char * error);

## Pre-requisite: You have to know your last commit message from your deleted branch.
git reflog
# Search for message in the list
# a901eda HEAD@{18}: commit: <last commit message>

# Now you have two options, either checkout revision or HEAD
git checkout a901eda 
# Or
git checkout HEAD@{18}

# delete local tag '12345'
git tag -d 12345
# delete remote tag '12345' (eg, GitHub version too)
git push origin :refs/tags/12345
# alternative approach
git push --delete origin tagName
git tag -d tagName

How Software Companies Die

Orson Scott Card

The environment that nurtures creative programmers kills management and marketing types - and vice versa.

Programming is the Great Game. It consumes you, body and soul. When you're caught up in it, nothing else matters. When you emerge into daylight, you might well discover that you're a hundred pounds

The Last Question by Isaac Asimov, LET THERE BE LIGHT!

Comic version

The Last Question by Isaac Asimov © 1956

The last question was asked for the first time, half in jest, on May 21, 2061, at a time when humanity first stepped into the light. The question came about as a result of a five dollar bet over highballs, and it happened this way:

Alexander Adell and Bertram Lupov were two of the faithful attendants of Multivac. As well as any human beings could, they knew what lay behind the cold, clicking, flashing face -- miles and miles of face -- of that giant computer. They had at least a vague notion of the general plan of relays and circuits that had long since grown past the point where any single human could possibly have a firm grasp of the whole.
