• Thinking Like an Architect - InfoQ

  tags: blog

  • Thinking Like an Architect
  • This article represents the talk, which starts by explaining the roles of an architect and the concept of connecting levels.
  • metaphors to make complex technical concepts more relatable
  • While discussing topics like high automation levels, cloud infrastructure, and DevOps can be exhilarating for technical teams, CIOs or heads of IT are more concerned about avoiding security breaches, ensuring high availability, and maintaining cost efficiency. Hohpe outlines how to bridge these perspectives: the technical innovations directly address these CIO-level priorities, but architects riding the elevator have to connect the dots between the different levels. For example, automation assures consistent patch levels, which in turn improves security.

• Strengthening data security in AWS Step Functions with a customer-managed AWS KMS key | AWS Compute Blog

  tags: blog

  • KMS key policy and IAM identity policies determine who decrypts and access various aspects of the state machine, including the definition, execution details, and input/output payload transitions for each tas
  • Apply these security guardrails using customer-managed AWS KMS keys at the organizational unit, business unit, or at the individual account level.

  • AWS Identity and Access Management policies, permission boundaries (IAM)

     

    You control access in AWS by creating policies and attaching them to AWS identities or resources. A policy is an object in AWS that, when associated with an identity or resource, defines their permissions. AWS evaluates these policies when a principal (user or role session) makes a request. Permissions in the policies determine whether the request is allowed or denied. Most policies are stored in AWS as JSON documents. In IAM, a permissions boundary is used to set the maximum permissions that an identity-based policy can grant to an IAM entity (users or roles). An entity's permission boundary allows it to perform only the actions that are allowed by both its identity-based policies and its permission boundaries.

• Full scan of 1 cubic millimeter of brain tissue took 1.4 petabytes of data, equivalent to 14,000 4K movies — Google's AI experts assist researchers | Tom's Hardware

  tags: blog

  • A recent attempt to fully map a mere cubic millimeter of a human brain took up 1.4 petabytes of storage just in pictures of the specimen
  • We did the back-of-napkin math on what ramping up this experiment to the entire brain would cost, and the scale is impossibly large — 1.6 zettabytes of storage costing $50 billion and spanning 140 acres, making it the largest data center on the planet.
  • The cubic millimeter of brain matter is only one-millionth of the size of an adult human brain, and yet the imaging scans and full map of its intricacies comprises 1.4 petabytes, or 1.4 million gigabytes. If someone were to utilize the Google/Harvard approach to mapping an entire human brain today, the scans would fill up 1.6 zettabytes of storage. 
  • Taking these logistics further, storing 1.6 zettabytes on the cheapest consumer hard drives (assuming $0.03 per GB) would cost a cool $48 billion, and that's without any redundancy. The $48 billion price tag does not factor in the cost of server hardware to put the drives in, networking, cooling, power, and a roof to put over this prospective data center. The roof in question will also have to be massive; assuming full server racks holding 1.8 PB, the array of racks needed to store the full imaging of a human brain would cover over 140 acres if smushed together as tightly as possible. This footprint alone, without any infrastructure, would make Google the owner of one of the top 10 largest data centers in the world, even approaching (if not reaching) the scale of Microsoft and OpenAI's planned $100 billion AI data center.

  • this small sample — one-millionth of the total human brain and about 3 mm long — requires more than a million Gigabytes of data: 1.4 Petabytes. This is the largest dataset ever made of human brain structure at this resolution.

  • Note taking example

     

    Imagine you heard the following in a lecture:

     

    "The United Kingdom’s population, at around sixty million, is similar to that of Italy, but Italy’s population is now shrinking because its birth rate has fallen below its death rate. The UK’s population is still growing, albeit very slowly – at a rate of 0.09% between 1995 and 2000."

       

     

     

        

     

                   

     

       

       

    Your notes could look like: 

     

    UK pop c60m ≈ I. BUT I. ↓ due BR < DR – cf. UK ↑ slow ie 0.09% 95 – 2K

• data annotation: Indian gig workers toil at frontlines of AI revolution - The Economic Times

  • As we are heading towards increasing complexity of training multimodal LLMs across text, speech, image, video, code etc., especially in low-resource languages such as those in India, skilled annotators will be required to build ethical guardrails into these innovations,” he added.
