EP75 - AskDeveloper Podcast - API Security with Ahmed Elemam

هل محبين و متابعين التكنولوجيا في المنطقة العربية يجب عليهم التحدث و الكتابة بالعربية؟ هل من يود تعلم التكنولوجيا في المنطقة العربية عليه أن يجيد اللغة الانجليزية و يتجه للمصادر الأجنبية؟
Should Arabic technology enthusiasts and workers speak and write in Arabic? should people who wish to learn about IT go for Arabic or English resources?

EP76 - AskDeveloper Podcast - بعتني بكام يا عشري - عن موجة التسريحات في شركات التكنولوجيا

What it will take to have the middle east region create more startups:

1. Entrepreneurs and avoid the fear of failures
2. Infrastructure (internet, electricity, payments)
3. Education
4. Investments
5. Social connector (this is an important one - almost always ignored - Geekwire used to this in Seattle, etc..)
6. Exits. Hard to in our region with less M&A and IPOs but they will come with time.
7. Alumnis network of successful startups

Georges is a software engineer that worked previously at Microsoft, Uber and Airbnb.

He is currently helping startups, writing a technical newsletter at https://www.softwareengineeringtidbits.com/ and teaching a cohort based software engineering course at maven: https://maven.com/georges-el-khoury/mastering-software-engineering

EP79 - AskDeveloper Podcast - ازاي يبقى عندنا شركات ناشئة أكثر مع جورج الخوري

الحلقة 35 من راديو اسأل مطور, في هذه الحلقة نستعرض موضوع المنطق للمبرمجين.
- Abstraction
  ○ 1+1 = 2 almost always not true
  ○ If 1 orange + another orange, what about the size of each, the taste ... etc
  ○ For this to be true some abstraction is required
  ○ Abstraction is removing some details to simplify reality modeling and perception
  ○ Programming is in huge part an art of abstraction
  ○ "Leaky abstraction" Spolsky's post. 
 - Perception
  ○ This table has four legs
  ○ This table is beautiful
  ○ The first statement the signifier and signified are adjacent while the second statement there is a space for interpretation
  ○ Some signifiers has wide meanings or narrow, and different people perceive it differently
  ○ Role of agile development in addressing perception issues
 - Deduction

EP80 - AskDeveloper Podcast - Software Architecture

المرة دي حندردش مع د وليد عمار عن الذكاء الصناعي و تأثيره على المجتمع, د وليد من خبراء الذكاء الصناعي و من اللي اشتغلوا في المجال سواء من أكثر من زاوية, سواء من زاوية الأكاديميا و البحث العلمي, أو من الناحية التطبيقية و العملية. 

- Did scientific innovation (eg, AI) improve our lives?
- How does early stage scientific innovation translate into economic progress?
- Can AI be used to build more advanced weapon?
- Who is in charge?

Waleed Ammar is the co-founder of a mission-driven AI startup and a product manager at the Allen Institute for Artificial intelligence (AI2). Before rejoining AI2 this year, Waleed was a senior research scientist at Google, where he helped develop transformer-based models for generating DNA sequences based on PacBio long-reads which significantly reduced variant-calling errors [Nature Biotech'22]. He also helped develop task-oriented dialog systems which are more robust to disfluencies, code-switching and user revisions [arXiv'23]. Prior to joining Google, Waleed led the Semantic Scholar research team's efforts to develop ML-based methods to facilitate access to the literature [e.g., NAACL 19], build a knowledge graph of the scientific literature [NAACL'18], and use this wealth of information to identify systemic social problems in science [JAMA'19]. He also occasionally teaches courses at UW linguistics as an affiliate faculty member. In 2016, Waleed received a Ph.D. degree in artificial intelligence from Carnegie Mellon University. Before pursuing the Ph.D., Waleed was a research engineer at Microsoft Research and a web developer at eSpace Technologies. Outside work, Waleed spends most of his time on the water or in dancing studios.

Information Security
 1. Introduction
  ○ Security by obscurity
   § Steganography
    □ Hiding data inside another form of data, like using non-used bits in image to hide a message
     § Cool, but not practical.
     § Disadvantages
      ◊ Algorithm secrecy vs. key secrecy
  ○ Cryptography is everywhere and yet if done right, you can barely see it.
  ○ Goals: 
   § Confidentiality
    □ Secrets stay secret.
   § Integrity
    □ Data is not tampered with.
   § Non-Repudiation
    □ No party can deny sending messages.
   § Authentication
    □ Each party can ensure that the sender is what they expect.
  ○ Cryptography
   § Hashing
   § Encryption
   § Signing
   § Protocols
  ○ Random Number Generators
   § Extremely important, almost all encryption/hashing strength is affected by how random the random number generator is.
   § Don't use simple random number, use a cryptographic random number generator with a sophisticated source of entropy.
   § Pseudorandom number generator
   § Dual_EC_DRBG random generator backdoor
 2. Body
  ○ Hashing (one Way)
   § Properties
    □ Fixed length output no matter what size the input was
    □ Very easy to compute the hash of a given message, however very hard to compute from a hash the corresponding input.
    □ Mathematically infeasible to generate a message that has a given hash
    □ Any modification to a message produces a completely different hash that has no relationship to the original message's hash.
    □ It is mathematically infeasible to find two messages with the same hash. Hash Collision
   § Hashing Functions
    □ Provides data integrity, however lacks authentication
    □ Examples
     ® MD5 
      ◊ Considered Insecure
     ® Secure Hash Family SHA-X, Sha-1, Sha-2 [Sha256, Sha512], Sha-3
      ◊ Sha-1 is considered insecure.
      ◊ Sha-1, Sha-2 designed by NSA
      ◊ Sha-3 is not designed by NSA, Competition winner.
    □ Attacks
     ® Brute force
      ◊ CPU's are getting faster and cheaper every day.
      ◊ GPU's are getting faster and cheaper every day.
      ◊ Special Hash calculating hardware is becoming more available especially with the BitCoin push.
     ® Rainbow table attacks
      ◊ Pre-Calculated tables where you can reverse lookup a hash to a value
      ◊ Try www.crackstation.net
   § Hash Message Authentication Codes (HMAC)
    □ Adds authentication to integrity
    □ Can be used with all previous algorithms, HMACMD5, HMACShA1, HMAC256 … etc.
   § Salted Hash
    □ Adds random salt to mitigate rainbow table
    □ Salts are unique per record, and not a secret.
   § Password Based Key Derivation Function (PBKDF2)
    □ RSA Public Key Cryptographic Standard PKCS #5 Version 2.0
    □ Internet Engineering Task Force RFC 2898 Specification
     ® Adds a lot of iterations to slow it just enough to mitigate brute force (default 50,000 iterations)
     ® Adds random salt to mitigate rainbow table
    □ Disadvantage: It can be easily implemented with hardware which makes it vulnerable to bruteforce even with high number of iterations
   § Bcrypt
    □ Password Hashing function
    □ State of the art password hashing
   § Usages
    □ Integrity Check
Password Storage

- Quick history
  ○ Distance learning
