الحلقة السادسة و الثلاثون من راديو اسأل مطور, نناقش في هذا الأسبوع أهمية نظم حفظ و تنظيم الكود Source Control و نقارن بين أنواعها المختلفة و نتكلم باستفاضة عن Git

What is source control
Why do I need Source Control
Source control absence from official CS curriculum is a disaster
Source control can be as important as If Else statements
Important for individuals. Vital for teams
Types of Source Control Systems
	Centralized (Traditional)
		CVS
		SVN - Subversion.
		TFS
	Distributed
		Git
		Mercurial 
Awesome Git Features
	Stash
	Branching with no overhead
	Local Commits (never lose a thing)
	Rewriting History (rebasing)
Git vs GitHub
	GitLab
	Bitbucket
Using GitHub in non-programming projects


EP36 - Source Control And Git

Introduction
What is a package?
What is a Package Manager?
Why Do we need Package Manager?
Pros and Cons
	Pros
		Break your code into sharable components.
		Reduce build times.
		Easy to find well-made packages to speed up development.
		Resolving versioning in a clean way.
	Cons
		Sometimes packages don't play well together
		Too many package managers with very little differences
Examples
	Ruby Gems (was that the first one?)
	Python Pip
	NuGet
	NPM
	apt-get
	OneGet
	Chocoloty
	Bower
	Yum
	pacman


EP38 - Package Managers

	• What's wrong with the world as it is today?
		○ Gatekeepers and Walled Gardens 
		○ The Master Switch by Tim Wu
			▪ Tim Wu is the one who coined the Net Neutrality term.
			▪ This book tells the story of how every communication medium starts a revolution that upsets the order, then eventually it gets controlled. The same thing could happen to the Internet.
	• Bitcoin
		○ Is this about money, or about technology
		○ Is this about the technology or bitcoin, or the technology of distributed money.
		○ How Bitcoin works. Video.
		○ Bitcoin mining in plain English.
	• Blockchain
		○ permissionless distributed database based on the bitcoin protocol that maintains a continuously growing list of data records hardened against tampering and revision, even by its operators. The initial and most widely known application of block chain technology is the public ledger of transactions for bitcoin, which has been the inspiration for similar implementations often known as altchains
		○ Trustless transactions
		○ Simple explanation of how Blockchain works.
	• Distributed hash tables
		○ class of a decentralized distributed system that provides a lookup service similar to a hash table
	• Git
		○ Git GPG Signature
	• BitTorrent
	• IPFS: Inter-Planetary File System
		○ Intro to IPFS 
		○ IPFS: Why We Must Distribute the Web (Video)
		○ How to Use IPFS to fix NPM
		○ HTTP is obsolete. It's time for the distributed permanent web
			▪ This page is actually served via IPFS
It covers important points: how IPFS does mutable data, how it does human-readable URLs.

○ Digital Signatures
   § Goal: verify Authenticity of a message.
   § Based on Asymmetric Cryptography.
   § Basic operations
    1. Public / Private keys generation (using some algorithm like RSA)
    2. Signing algorithm using the private key
    3. Signature verification algorithm using the corresponding public key
   i. Extending previous Example
    • Steps (Order is very important, bold stuff is the difference added to authenticate sender)
     ® Party 1 (Alice)
      1. Generates a random AES Session Key (32 bytes / 256 bits)
      2. Generates a random Initialization Vector (IV) (16 bytes / 128 bits)
      3. Encrypt the message to be sent using the AES Session Key & IV
      4. Calculate an HMAC of the encrypted message using the AES Session key
      5. Encrypt the AES Session Key using the Public Key of Party 2 (Bob) The recipient.
      6. Calculate Signature using the private signing key on the HMAC
      7. Sends a packet of (Encrypted Message, Encrypted Session Key, Initialization Vector, HMAC, and Signature) to Bob
     ® Party 2 (Bob)
      1. Decrypts Session key using his Private Key
      2. Recalculates the HMAC of the encrypted message (Validates message integrity)
       } If HMAC check pass
        – Verify digital signature using Alice Public Key
         w If signature verification pass
          w Decrypts the message using the decrypted AES Session Key and Initialization Vector
         w Otherwise, identity of the sender couldn't not be verified, reject message.
       } Otherwise, rejects the message because of integrity check failure.
    • Why Order matters?
     ® Timing Side-Channel Attacks
     ® Padding-Oracle Attack
     
  ○ Protocols
   § TLS/SSL
    • How TLS/SSL Works?
    • Mitigates against
     ® Man in the Middle Attacks
     ® Authentication, so the client can be sure it is talking to the correct destination.
   § Public Key Infrastructure (PKI)
    • Certificates aka X.509 Certificate (Sha-1 Signature Issues)
     ® A digitally signed file
     ® Identifies (Computer / User / Device)
     ® Has Public & Private Key, only the certificate owner has the Private Key.
     ® Has Expiration date
     ® Information about the CA that issued the cert 
     ® X.509 Extension Attributes (like Usage attribute)
     ® Revocation Information.
    • Certificate Authority (CA) (CNNIC, WoSign)
     ® Issues, signs and manages certificates.
     ® Famous certificate authorities (Verisign, GoDaddy, … etc).
    • Trust Chains
     ® CA's can delegate the signing job to subordinate CA's
      ◊ Root CA's signs an intermediate signing certificate to the subordinate CA
     ® The subordinate CA can then issue certificates
     ® To validate a certificate, the client validates the signatures of all the intermediate stages and make sure all of them are linked to a Trusted CA
    • Certificate Revocation Lists (CRL's)
     ® When a certificate is compromised (Private Key leaked) it will be published on the CRL, so each time the cert is validated, the CRL list is checked in case cert is revoked.

  ○ MITx launched by MIT in response to commercialization of MOOC, then joined by Harvard and renamed edX
 - Cost
  ○ Content is free
  ○ edX offers certificate for 100$ for most courses
  ○ Coursera have some quizzes and grading exercises only for paying students
  ○ Udacity has nano-degrees with projects reviewed only for paying students
 - Interdisciplinary learning
  ○ Importance
  ○ Examples

	• What defines ethical? -- * 
	• Failing and realizing why it happened.
	• Respect your own capabilities with consideration of (is it hard enough?)
	• What do you do at work?
	• You as a brand, what message do you want to deliver? "What you do is perceived as who you are"
	• Dare to disrupt your life, When nothing is happening for while it is important to look on what have you done for the next step, what you are doing and the next months is basically the present (it is planned and determined and probably the outcome of it is known)
	• The need to explore other areas to empower the current moment.
	• Are you ready to answer all questions in a meeting? 
	• Do you intentionally mislead people with subtle language/words?
	• Starting a startup and how much I wasn't ready for it, how bad I treated people and how much effort did I have to work on my attitude?
	• Are you really as good/bad as you think you are?
	• Let's discuss "There is nothing noble in being superior to your fellow man; true nobility is being superior to your former self." - Ernest Hemingway
	• Opinions and Facts, the critical need to distinguish both from each others.
	• Where/Who/What you are doesn't define you, Anything is subject to change and none should be defining your future.
	• Assuming (good intention)/(Positive attitude) when listening to people changes how people perceive you as ally or adversary
	• Why good language matters at work.
	• What is the difference between pushing the limits and (breaking the law / respecting others / etc)
	• Your values and what drives you.
	• Let's see why greedy will fall short to help you achieve your targets.
	• The multi modes for writing code, communicating and looking back.
	• What do you do while your work is compiling.
	• The balance of listening to others and going your own way. 
	• Picking up answers from Stack overflow. -- * 
When it works, do you know why it works? -- *
