Мне вообще никто не нужен, сам себе погрею ужин. Самодостаточная Data
Привет, на связи Лука. Мне всегда было интересно узнать больше о чистой архитектуре и о том, как построить систему, которая будет простой, но при этом выполнять всё, что от неё требуется. Естественно, без ухода в крайности, результат — наше всё, в булочную на такси не поедем. Со временем вырисовываются какие-то паттерны и принципы, к которым лежит душа. У каждого свои: кто-то горит TDD, кто-то ATDD, FDD, BDD и прочими DD. Я же больше всего прикипел к DDD, причём первая D тут варьируется: угораю как по Domain , так и по Data . И что дальше?

Correctness is clearly the prime quality. If a system does not do what it is supposed to do, then everything else about it matters little.

The most important property of a program is whether it accomplishes the intention of its user.
— C. A. R. Hoare
Years ago I started writing a #specification for a family of binary file formats with three goals:
- Extremely simple for mmapped access
- Frozen in time (no versioning)
- No complex algorithms to read/write the data
I still think there's value to those formats, since the tasks they try to ratify come up time and again, and there seems to be no simple equivalent
I never finished it because I feel I still need more feedback. If you're interested, please have a read:
shirakumo.github.ioSF3 SpecificationSF3 - The Simple File Format Family is a specification of a number of simple binary file formats.
Inside every large program, there is a small program trying to get out.

Regular expression pattern modifiers · A look at a feature expected in ECMAScript 2025 https://ilo.im/161s45

ilo.imECMAScript feature: regular expression pattern modifiersTraditionally, we could only apply regular expression flags such as i (for ignoring case) to all of a regular expression. The ECMAScript feature “Regular Expression Pattern Modifiers” (by Ron Buckton) enables us to apply them to only part of a regular expression. In this blog post we examine how they work and what their use cases are. Regular expression pattern modifiers attributes reached stage 4 in October 2024 and will probably be part of ECMAScript 2025.

ilo.imECMAScript feature: import attributesThe ECMAScript feature “Import Attributes” (by Sven Sauleau, Daniel Ehrenberg, Myles Borins, Dan Clark and Nicolò Ribaudo) helps with importing artifacts other than JavaScript modules. In this blog post, we examine what that looks like and why it’s useful. Import attributes reached stage 4 in October 2024 and will probably be part of ECMAScript 2025.
Sometimes the problem is to discover what the problem is.
