What it does
Hi, I’m Jakub Linowski and the goal of Fastforward is to find repeatable patterns with the highest probabilities of lifting conversion rates. To do this we run experiments with trusted companies open to testing similar ideas. So far we have identified 71 patterns based on 117 tests and we're adding new tests each month.
Reach higher conversions faster by repeating what worked for others and avoiding what failed.
Unsubscribe any time . Receive up to 1 email per week with new UI patterns and test results that we discover. Be it landing pages, funnels, ecommerce sites or apps, they all get better with UI changes backed by positive design experiments - the more the better. And so we actively publish results of amazing companies that learn from experimentation: Test #668 on by Oshri Maidanik Sep 13, 2026 Desktop Mobile Checkout X.X% Sales This experiment ran on an ecommerce store utilizing Shopify's checkout. The treatment compared the checkout experience with and without a limited-time countdown timer. Impact on placed orders was measured. The A/B test ran using PrettyDamnQuick software.

Speeding up LLM inference 2x times (possibly)2024 · asciinema.org · ▲419Here's a project I've been working on for the last few months. It's a new (I think) algorithm, that allows to adjust smoothly - and in real time - how many calculations you'd like to do during inference of an LLM model. It seems that it's possible to do just 20-25% of weight multiplications instead of all of them, and still get good inference results. I implemented it to run on M1/M2/M3 GPU. The mmul approximation itself can be pushed to run 2x fast before the quality of output collapses. The inference speed is just a bit faster than Llama.cpp's, because the rest of implementation…

Faster FastAPI with simdjson and io_uring on Linux 5.192023 · github.com · ▲290A few months ago, I benchmarked FastAPI on an i9 MacBook Pro. I couldn't believe my eyes. A primary REST endpoint to `sum` two integers took 6 milliseconds to evaluate. It is okay if you are targeting a server in another city, but it should be less when your client and server apps are running on the same machine. FastAPI would have bottleneck-ed the inference of our lightweight UForm neural networks recently trending on HN under the title "Beating OpenAI CLIP with 100x less data and compute". (Thank you all for the kind words!) So I wrote another library. It has been a while since I have…
