What does a software architect do?

What does a software architect do?

Comments 0 Comment

A software architect is a programmer; and continues to be a programmer. Never fall for the lie that suggests that software architects pull back from code to focus on higher-level issues. They do not! Software architects. are the best programmers, and they continue to take programming tasks, while they also guide the rest of the team toward a design that maximizes productivity. Software architects may not write as much code as other programmers do, but they continue to engage in…

Three Paradigms in Software Architecture

Three Paradigms in Software Architecture

Comments 0 Comment

The three paradigms of software architecture are structured programming, objected-orient programming, and functional programming. Each can be summarized as follows: Each of the paradigms removes capabilities from the programmer. None of them adds new capabilities. Each imposes some kind of extra discipline that is negative in its intent. The paradigms tell us what not to do, more than tell us what to do. In another way, it is to recognize that each paradigm takes something away from us. The tree…

What is Clean Architecture?

What is Clean Architecture?

Comments 0 Comment

Clean Architecture is a software design philosophy introduced by Robert C. Martin (Uncle Bob) to create maintainable, flexible, and scalable systems. It focuses on organizing code in a way that separates concerns and ensures high cohesion and low coupling between components. Here’s a summary of its key principles: Layered Structure: Clean Architecture divides the system into layers with different responsibilities. The core idea is to isolate business logic from external concerns (UI, databases, frameworks, etc.), ensuring that the core of…

Spring Boot Caching with Redis

Spring Boot Caching with Redis

Comments 0 Comment

요즘 Spring을 활용하는 방법에 익숙해 지려고 노력하고 있다. 사실 Spring은 거의 15년여 전 Spring Framework 초기에 잠깐 사용해보고 그 이후는 경험이 전무한 터라 개념 정도는 얘기할 수 있을지라도 요즘 개발자들과 Spring 활용에 대해 말을 썩을 수 있는 처지가 못된다. 이 참에 Spring에 녹아있는 핵심적인 기술들을 하나씩 꺼내와서 이해하고 정리해 보려고 한다. 이 글은 그 시리즈의 첫 번째로 Spring Cache에 대한 내용이다. 인터넷에서 흔히 소개되고 있는 내용들 보다 좀 더 깊숙이 들어가서 어떤 매커니즘에 의해 Caching이 적용되고 동작하는 지 살펴보도록 한다….

AI systems based on two model types

AI systems based on two model types

Comments 0 Comment

The current frontier of AI systems is based on two model types(they are almost identical under the hood, but their behavior is notably different in practice, hence the distinction) Pre-trained models, also known as ‘non-reasoning models’ These are the famous ‘Large Language Models’, or LLMs, gigantic AI models trained on as much as data as possible, reaching double digits of trillions of words (for reference, Lama 3.1 405B was trained on 15 trillion tokens ~ 11-12.5 trillion words, and DeepSeek…

How did DeepSeek build its A.I. with less money?

How did DeepSeek build its A.I. with less money?

Comments 0 Comment

The Chinese start-up used several technological tricks, including a method called “mixture of experts” to significantly reduce the cost of building the technology. A.I. companies typically train their chatbots using supercomputers packed with 16,000 specialized chips or more. But DeepSeek said it needed only about 2,000. DeepSeek engineers needed only about $6 million in raw computing power, roughly one-tenth of what Meta spent in building its latest A.I. technology. What exactly did DeepSeek do? How are A.I. technologies built? Companies…

DeepSeek just Exposed the Rot at the Core of the AI Industry

DeepSeek just Exposed the Rot at the Core of the AI Industry

DeepSeek made two critical changes. Firstly. the architecture. OpenAI uses an AI architecture known as “fully dense”. This basically means that the architecture is comprised of a single, vast network that processes every request with all its parameters and data points. This is incredibly computationally dense, but the idea is that it can make it more capable in a broader application. DeepSeek is instead much more picky and uses a “mixture of experts” architecture. In this approach, the AI is…

What is Distillation in A.I. ?

DeepSeek shook up the U.S. stock market, and it’s still creating shock wavers around world. But the newest allegation is that DeepSeek actually used a particular process to put together its training data, and it’s one that some consider to be a little shady. The new U.S. president’s AI and crypto czar David Sacks is one of those who is getting in on the action, saying in an interview with Fox News that there was “substantial evidence” that this kind…

DeepSeek’s breakthrough on cost challenges the “bigger is better” narrative that has driven the A.I. arms race in recent years by showing that relatively small models, when trained properly, can match or exceed the performance of much bigger models. That, in turn, means that A.I. companies may be able to achieve very powerful capabilities with far less investment than previously thought. And it suggests that we may soon see a flood of investment into smaller A.I. start-ups, and much more…

A Story about Building Container Images

최근 들어 Docker Container에 대해 깊은 이해가 필요하여 이 참에 어렴풋이 알고 있던 Container에 대해 제대로 함 알아보자는 요량으로 관련 서적을 뒤지다가 가장 최근의 책이라고 여겨지는 “Docker Deep Dive 2024 edition” 을 골라 습독을 했다. 대략 Docker Container에 대한 내용은 익히 알고 있던터라 개념적 이해는 쉽게 지나갔지만 실제 이 기술을 이용하고 싶을 때 막히지 않을 정도로 몸에 익혀보자는 생각으로 책에 나온 샘플 코드를 이리 저리 내가 활용해 보고 싶은 시나리오로 변형하고 적용하다 보니 계획했던 2주 보다 시간이 좀 더 걸렸다….
