ES2026 có gì mới: 7 tính năng JavaScript giúp bạn xóa bớt helper tự viết
ECMAScript 2026 — bản đặc tả JavaScript thứ 17, được Ecma phê duyệt vào tháng 6/2026 — mang tới 7 tính năng mới mà không thêm bất kỳ cú pháp nào. Cả 7 đều thay thế những hàm helper mà gần như codebase nào cũng tự viết: upsert cho Map, giữ nguyên số lớn khi parse JSON, cộng số thực chính xác hơn.

No, what's happened is that I have repeatedly asked you what a "known good codebase" would be and it doesn't escape my notice that you keep dodging the question.

Lauren Tan of SpaceXSI argues for constraining AI coding agents through codebase design and lint rules before prose instructions. A video of her talk went up 144,376 views in 12 hours, about 79x the typical pace of other AI-tool videos SteadyVane tracks on YouTube.
How to scale AI coding agents with architecture, lint rules and layered verification
Lauren Tan, a Principal Engineer at SpaceXSI, gave a talk at the AI Engineer Code summit on keeping AI coding agents reliable. Her 'trust pyramid' puts codebase design and static analysis ahead of prose instructions. One example is explicit directories with lint rules that forbi…

AI is making code cheap to generate, but extremely expensive to understand, threatening fundamental engineering skills, troubleshooting, and long-term codebase ownership.
Are we trading code quality for AI speed?

The 30-Day Rescue Plan for a Codebase Nobody Can Explain

Okay, so give an example of a known good codebase.

Yknow it'd be funny if someone could reverse engineer and decompile sonic genesis on gba just to figure out what the hell is going on with it
I genuinely wonder how salvageable the codebase is

Helping Developers Writing Code Analyzer Queries
Generating Complex Code Analyzers from Natural Language Questions
Many software development tasks, such as implementing features and fixing bugs, begin with developers posing questions about a codebase. However, answering questions about codebases that span millions of lines of code across thousands of files is non-trivial. Standard tools like grep cannot answer questions requiring semantic or inter-procedural reasoning, and large language models (LLMs) struggle with large codebases due to resource and context constraints. In this paper, we present Merlin, a new system for answering free-form questions that require analytical reasoning about code. Merlin integrates an LLM with CodeQL, a program analysis framework that supports expressive queries over large codebases. We face two principal challenges in the design of such systems: First, program analysis queries are diverse and semantically complex; as a result, even syntactically well-formed queries frequently produce degenerate/empty results. Furthermore, relatively few CodeQL queries are available online, limiting the out-of-the-box effectiveness of LLMs as CodeQL query generators. We address these challenges by developing a RAG-based iterative query-generation approach and a novel self-test technique. Our query debugging technique builds on the idea of assistive queries, which generate concrete witnesses that expose and explain semantic flaws in candidate queries. We evaluate Merlin through both experimental and user studies. Over a set of natural language questions derived from common bug-finding tasks, Merlin discovered not only the majority of software issues reported by other approaches, but also issues that would have otherwise remained undetected. Through a within-subject user study, we found that access to Merlin increased task accuracy by an average of 3.8* and simultaneously reduced the time for programmers to complete all tasks by 31%.

Audiosurf but for a codebase

"Let's just add a quick fix."

One quick fix becomes three workarounds. Then another developer builds around them.

Eventually, nobody wants to touch that part of the codebase.

When does a temporary solution become technical debt worth addressing?

Personally I don't like this direction we're going in because I understand the importance of knowing my codebase. I also know the importance of training people how to be good engineers.

But I also really fucking get why so many devs are fed up of reinventing wheels every 5 minutes.

One issue I have with some channels is I feel like I have to leave off some information as context because that would end up being a total info dump.

When knowing how long Ive written scifi is important context for why my codebase feels how it does.

La dernière fois qu'un client m'a demandé de bosser sur des des Specs et une vision Produit... je l'ai fait.

Et je lui ai aussi livré un prototype complet de son application, sur sa Codebase.

Et on ne parle même pas d'une application simple, mais vraiment de comportements complets :

I guess that's why most fictional writers in series with multiple novels don't transition well into codebase development unless they've already in that career path.

And even less usual: a codebase based on over a decade of your novels and short stories.

This post is just bad.

Here, the "translation" could actually be just... wrong.

Sites ≠ places
100s of time per second ≠ 1k connections every 4-5 seconds

"Places" could be intranet, or even the same codebase, and the original phrasing doesn't imply a uniform load which behaves differently.

Case and point. Biggest project of my career wrapped up recently. Forced to use agents.

It took the team the exact same amount of time as without it and our codebase is the worse for it.

Its kind of fascinating how the YT algorithm is unsure how to categorize me as pro-AI or anti-AI, or whether I'm in computer science, or more creative.

It's fantasy language used for a game engine codebase.
