Alright, let’s not waste any invaluable time and bounce proper into this month’s updates.

Here is what you missed in October 2025 as a Net Developer…

Pareto CSS 💅🏻

What is the least quantity of CSS you want for a good trying website? Someone explored this question and I do love the simplicity of all of it.

All the pieces in our trade is continually altering however there may be one rule that by no means modifications: simplicity over complexity.

Octoverse Outcomes 🐙

Large knowledge level that’s launched yearly from Github: Octoverse, and there are some stunning issues. Right here is the takeaway:

Builders created greater than 230 new repositories each minute, merged 43.2 million pull requests on common every month (+23% YoY), and pushed practically 1 billion commits in 2025 (+25.1% YoY)—together with a file of practically 100 million in August alone.

This surge in exercise coincides with a structural milestone: for the primary time, TypeScript overtook each Python and JavaScript in August 2025 to grow to be probably the most used language on GitHub.

I really feel like we needs to be together with JavaScript and TypeScript collectively…Additionally it seems like AI slop is actual.

HTML’s Greatest Saved Secret 🥢

Each developer is aware of . It’s the workhorse of the online.

However

? Most have by no means touched it. Some don’t even understand it exists. Can you guess what it does?

TLDR: we’re all low cost and simply care in regards to the value.

P.S. enjoyable factor from this month… now you can use Claude Code inside your web browser.

New Libraries and Instruments 🗿

There are a ton of shiny new libraries and instruments each month which is why I’ve this devoted part for them…

• ChatKit – framework for constructing high-quality, AI-powered chat experiences.

• React Native 0.82 is out! This one runs completely on their new structure.

• Bun 1.3 is right here, the brand new fashionable JavaScript runtime.

• NodeJS 25.0.0 is right here with a serious JSON.stringify efficiency enchancment.

• NextJS v16 is out, however I’ve an excessive amount of NextJS fatigue to even care.

Information Across the World 🗺

Large Tech Information aka AI Information 🏢

• I’ve to start out this part with the worst thought of the month, and probably the worst thought of the yr award (though robust to beat something created by Meta): OpenAI Atlas – have you ever ever needed to have OpenAI see your complete search historical past and all of the stuff you search for on-line and feed it into ChatGPT? Effectively, that is what you are able to do with Atlas.

• OpenAI launched some enterprise numbers: $4.3b in income, $13.5b in loss. I like this take from a commenter:

I feel individuals are massively underestimating the cash they may come from advertisements sooner or later. They generated $4.3B in income with none promoting program to monetise their 700 million weekly lively customers, most of whom use the free product.

Google earns primarily all of its income from advertisements, $264B in 2024. ChatGPT has extra shopper belief than Google at this level, and quite a few methods of inserting sponsored outcomes, which they’re beginning to experiment with with the latest announcement of direct checkout.

The largest concern IMO is how good the open weight fashions popping out of China are, on shopper {hardware}. However so long as OpenAI stays the go-to for the common shopper, they’ll be superb.

• OpenAI additionally introduced Apps and Apps SDK… a manner for builders to create apps you may chat with proper inside ChatGPT. In addition they introduced AgentKit which offer you new instruments for constructing, deploying, and optimizing brokers.

• Qualcomm is buying Arduino.

• Anthropic introduced Claude Haiku 4.5. 5 months in the past, Claude Sonnet 4 was a state-of-the-art mannequin. At present, Claude Haiku 4.5 provides you related ranges of coding efficiency however at one-third the associated fee and greater than twice the velocity.

• One other Anthropic announcement: Claude Skills, primarily Abilities are folders and information with textual content that embrace directions, scripts, and assets that Claude can load when wanted, ideally written by you and the “teacher”.

• Large information out of Apple: the M5 chip is coming: M5 delivers over 4x the height GPU compute efficiency for AI in comparison with M4, that includes a next-generation GPU with a Neural Accelerator in every core, a extra highly effective CPU, a sooner Neural Engine, and better unified reminiscence bandwidth. Apple chip is just about dominating the non-public pc area proper now.

• AWS had a serious outage this month that resulted in plenty of companies being down (together with ZTM), however the excellent news is that plenty of great memes got here out of it. Here is what happened.
