In this article, you will learn seven common token-waste patterns in production AI agent systems, and the architectural fixes that address each one. Topics we will cover include: How treating the context window as a system of record inflates costs and latency, and how to fix it with sliding windows and semantic summarization. How uncompressed tool results, static schema bloat, and naive retrieval patterns silently drain your token budget.

With emerging trends in AI, machine learning, and big data, 2026 brings a new wave of data science tools designed to streamline workflows and enhance productivity. In this blog, we’ll explore the must-know data science tools that can help you stay competitive and advance your career in the ever-expanding data science landscape.
With product engineering, figuring out what the requirements are is still most of the job. This post presents an interview model where LLMs can be used in interviews to roleplay as customers, and engineers talk to the models to extract requirements. The approach rewards candidates who think of edge cases, approach things sideways, and think about whole systems at once. It's relatively cheap and can be used in conjunction with a standard human interview.

Postgres 19 most likely won't be released until November and could possibly be postponed further. Several large features were reverted quite late in the beta period. AI has made it easier to identify bugs, and this has resulted in a lot more bug reports that the PostgreSQL committers have to work on. This has taken the focus off development of new features, as the project cares about quality.
Switching from pm2 to wattpm for process management, combined with smarter nginx load balancing and tuned garbage collection settings, cut compute costs by 38% on Booking's largest Node service. The team ran 30% fewer pods, reduced memory use by 20%, and cut tail latency by up to 10%. No application code changes were needed, and other teams could adopt the improvement by changing a single config flag.

AI News:
Meta has reportedly built a humanoid robot with Chinese robotics company Fourier, as it explores giving its Muse AI assistant a physical body. Max runs on Nvidia's Jetson Thor chip and has five-fingered hands that can pick up small bottles and toys. Development of Max 2 began in September, with improved hands, a projector, and additional sensors designed to help it navigate stairs.
The holiday streaming season is almost here
Are you ready? As revealed in our holiday playbook, Roku Ads Manager lets you easily set up, measure and optimize your self-serve holiday ad campaign. You can even create a shoppable ad unit that lets streamers buy directly from their remote.
This week’s U.S. midterms double as a referendum on data centers, with roughly 20 communities voting on bans or pauses, while OpenAI reportedly prepares a post-election push to rebrand the sites as “AI compute campuses.” Democrats are projected to flip the House Tuesday, which could end a two-year run of easy treatment in Washington for AI firms with close ties to Pres. Trump.
Elon Musk’s xAI faces a possible shutdown of the gas turbines powering Colossus 2 after a judge allowed an air pollution lawsuit to proceed. A federal judge rejected xAI's argument that its temporary gas turbines were exempt from air permit requirements. The NAACP estimates the turbines could release over 5,000 tons of smog-forming nitrogen oxides annually.
Some nights YouTube’s home page feels like it was picked for somebody else entirely. Andrej Karpathy had one of those nights on a Friday. He figured the feed was made for the typical viewer and not for someone like him. The next morning he built his own YouTube. He went looking on Hacker News. People there’ve been pointing each other to good videos for almost two decades.
Somebody poking around Gemini Notebook found a button they weren’t meant to see yet. It sits next to the other things Notebook can make from your files, and it’s called Comics. There’s a small Beta label on it. Gemini Notebook can already turn your own notes or docs into slides and videos. The Comics tile looks like it’d turn those same files into an illustrated story.

How to recreate the mega-viral ‘Subway Running Trend’ with Higgsfield AI

Open Higgsfield > ‘Video’ > ‘Create Video’ > ‘Higgsfield Genjutsu’, then choose ‘Motion Transfer’.
Open ‘Motion Library’ and search the ‘Community Trending’ feed for the train/subway performance; if it appears, select it directly. If not, upload this reference clip instead.
Upload 2–5 clear photos of yourself from similar angles so Higgsfield can keep your face and appearance consistent. Then, turn on ‘Prompt’ and use the following prompt:
Sample Prompt: “Recreate this train-performance trend using the person in my reference images. Preserve the exact phone-mounted camera movement, train motion, pacing, singing performance, city reveal, and shot timing. Keep my face, hair, outfit, and body proportions consistent throughout, with realistic lighting, motion, and facial performance.”
Set the output to 9:16 and 1080p, then click ‘Generate’.
Add Dua Lipa’s “Training Season” live audio inside Instagram or TikTok when posting— the current trend commonly uses that song.
