Greef: The world is becoming more transactional, from servers to serverless, and per second billing. You used to buy a server every three years or rent dedicated by the month, then an instance by the hour, and now every second there's a serverless transaction. In the same way from coal to clean energy, our energy so...

The wrong way to speed up your code with Numba

If your NumPy-based code is too slow, you can sometimes use Numba to speed it up....
If your NumPy-based code is too slow, you can sometimes use Numba to speed it up. Numba is a compiled language that uses the same syntax as Python, and it compiles at runtime, so it’s very easy to write. And because it re-implements a large part of the NumPy APIs, it can also easily be used with existing NumPy-based...

Lately I’ve been helping a colleague to add worker threads to his GUI-based Windows application. Thread programming can be tricky. Here are a few things I’ve learned along the way. Performance. This app does compute-intensive work. It is helpful to offload this very compute-heavy work to a worker thread. Doing this ...

Downloaded over 5 Billion times, NumPy is the most popular library for numerical computing in Python. It wraps low-level HPC libraries like BLAS and LAPACK, providing a high-level interface for matrix operations. BLAS is mainly implemented in C, Fortran, or Assembly and is available for most modern chips, not just C...

At Allegro, we use Kafka as a backbone for asynchronous communication between microservices. With up to 300k messages published and 1M messages consumed every second, it is a key part of our infrastructure. A few months ago, in our main Kafka cluster, we noticed the following discrepancy: while median response times...

The Impact of Pre-allocating Slice Memory on Performance in Golang During my code reviews, I often focus on whether the slice initialization in the code has allocated the expected memory space, that is, I always request to change from var init []int64 to init := make([]int64, 0, length) format whenever possible.

Version 0.10 of libjxl, the reference implementation for JPEG XL, has just been released. The main improvement this version brings, is that the so-called “streaming encoding” API has now been fully implemented. This API allows encoding a large image in “chunks.” Instead of processing the entire image at once, which ...
