18 Sep, 2025 We have all been there. Your software keeps growing and you feel the need to make it customizable. It is too soon for a full-blown UI with all the bells and whistles, so your pragmatic instinct suggests a text-based configuration file. Yes, that’s exactly it! You rejoice knowing the software’s configuration will be trivial to version control. Your pragmatic instinct is satisfied as well; the door remains open to creating a proper UI later, since it would be merely a graphical view

Semlib Semlib is a Python library for building data processing and data analysis pipelines that leverage the power of large language models (LLMs). Semlib provides, as building blocks, familiar functional programming primitives like map , reduce , sort , and filter , but with a twist: Semlib's implementation of these operations are programmed with natural language descriptions rather than code. Under the hood, Semlib handles complexities such as prompting, parsing, concurrency control, caching,

La-Proteina: Atomistic Protein Generation via Partially Latent Flow Matching Abstract. Recently, many generative models for de novo protein structure design have emerged. Yet, only few tackle the difficult task of directly generating fully atomistic structures jointly with the underlying amino acid sequence. This is challenging, for instance, because the model must reason over side chains that change in length during generation. We introduce La-Proteina for atomistic protein design based on a n

Is OOXML Artifically Complex?

Is OOXML Artifically Complex? A while ago, the official blog of LibreOffice published a provocative article: “An artificially complex XML schema as a lock-in tool.” Its target is Microsoft’s XML-based file formats — the Office Open XML (OOXML). The article alleges that, although Microsoft put its Office formats through standardization, the spec is engineered to be so complex that it obstructs interoperability with third-party software.
