Show HN: WordSea – Visual English Dictionary https://ift.tt/OVDpbSN

Show HN: WordSea – Visual English Dictionary Hi! My girlfriend and I created an app that allows you to "see" the meaning of words based on their definitions. We think it is sometimes easier to understand and remember a new word when you can visualize it. For some words, it is easy to do - you can search Google Images to quickly grasp the meaning. We wanted to extend this idea to more abstract words. Hope you find it useful! https://wordsea.xyz/ July 14, 2024 at 07:35PM

Show HN: Htmx Offline Mode https://ift.tt/wmzvl9U

Show HN: Htmx Offline Mode I wrote a pretty simple extension to HTMX that captures requests made if you lose internet or other connectivity to the server receiving the requests. Then, when you're back online, it replays requests. Maybe someone here would benefit from it. https://ift.tt/g17hJIF July 13, 2024 at 10:06PM

Show HN: An open-source backend for frontend framework built on Express.js https://ift.tt/iHEA3Vw

Show HN: An open-source backend for frontend framework built on Express.js Hey All! I started a project to create a simple API proxy server that would allow me to use third-party APIs in my frontend apps without exposing my API keys. This solved a common problem I faced: needing to interact with external services securely without building a full backend for every project. As I worked on it, the project evolved into something more comprehensive: a Backend for Frontend (BFF) Framework built on Express.js. This framework now helps you quickly spin up a backend for your client applications, especially useful when you're dealing with APIs you don't fully control. You can configure the BFF using a simple YAML file, and it comes with built-in policies for CORS, JWT validation, and rate limiting. If you need more customization, you can extend its functionality by writing custom Express middleware and handlers. I'd love to get your feedback and hear if this would be useful for your projects! https://ift.tt/cfudzl5 July 13, 2024 at 07:52PM

Show HN: Perf Sea – performance engineering for everyone https://ift.tt/2XV1x6H

Show HN: Perf Sea – performance engineering for everyone I have found that many companies don’t have time for performance engineering and leave random tunables incorrectly configured for their workload. Instead of solving the same problems over and over I wanted an open source place where people could collaboratively share their best practices, knowledge, and methodologies, because in performance engineering no one is really a competitor. It is under active development, but currently you can: * scan flamegraphs to match with optimizations * scan raw hardware counter events to generate high level metrics and insights * scan arbitrary command output for system configuration red flags All in the browser with a simple copy paste. https://perfsea.com/ July 12, 2024 at 06:09PM

Show HN: Mandala – Automatically save, query and version Python computations https://ift.tt/EQ9ve8V

Show HN: Mandala – Automatically save, query and version Python computations `mandala` is a framework I wrote to automate tracking ML experiments for my research. It differs from other experiment tracking tools by making persistence, query and versioning logic a generic part of the programming language itself, as opposed to an external logging tool you must learn and adapt to. The goal is to be able to write expressive computational code without thinking about persistence (like in an interactive session), and still have the full benefits of a versioned, queriable storage afterwards. Surprisingly, it turns out that this vision can pretty much be achieved with two generic tools: 1. a memoization+versioning decorator, `@op`, which tracks inputs, outputs, code and runtime dependencies (other functions called, or global variables accessed) every time a function is called. Essentially, this makes function calls replace logging: if you want something saved, you write a function that returns it. Using (a lot of) hashing, `@op` ensures that the same version of the function is never executed twice on the same inputs. Importantly, the decorator encourages/enforces composition. Before a call, `@op` functions wrap their inputs in special objects, `Ref`s, and return `Ref`s in turn. Furthermore, data structures can be made transparent to `@op`s, so that an `@op` can be called on a list of outputs of other `@op`s, or on an element of the output of another `@op`. This creates an expressive "web" of `@op` calls over time. 2. a data structure, `ComputationFrame`, can automatically organize any such web of `@op` calls into a high-level view, by grouping calls with a similar role into "operations", and their inputs/outputs into "variables". It can detect "imperative" patterns - like feedback loops, branching/merging, and grouping multiple results in a single object - and surface them in the graph. `ComputationFrame`s are a "synthesis" of computation graphs and relational databases, and can be automatically "exported" as dataframes, where columns are variables and operations in the graph, and rows contain values and calls for (possibly partial) executions of the graph. The upshot is that you can query the relationships between any variables in a project in one line, even in the presence of very heterogeneous patterns in the graph. I'm very excited about this project - which is still in an alpha version being actively developed - and especially about the `ComputationFrame` data structure. I'd love to hear the feedback of the HN community. Colab quickstart: https://ift.tt/vMlIRD4...

Show HN: Dut, a fast Linux disk usage calculator https://ift.tt/WRrtFwU

Show HN: Dut, a fast Linux disk usage calculator "dut" is a disk usage calculator that I wrote a couple months ago in C. It is multi-threaded, making it one of the fastest such programs. It beats normal "du" in all cases, and beats all other similar programs when Linux's caches are warm (so, not on the first run). I wrote "dut" as a challenge to beat similar programs that I used a lot, namely pdu[1] and dust[2]. "dut" displays a tree of the biggest things under your current directory, and it also shows the size of hard-links under each directory as well. The hard-link tallying was inspired by ncdu[3], but I don't like how unintuitive the readout is. Anyone have ideas for a better format? There's installation instructions in the README. dut is a single source file, so you only need to download it and copy-paste the compiler command, and then copy somewhere on your path like /usr/local/bin. I went through a few different approaches writing it, and you can see most of them in the git history. At the core of the program is a datastructure that holds the directories that still need to be traversed, and binary heaps to hold statted files and directories. I had started off using C++ std::queues with mutexes, but the performance was awful, so I took it as a learning opportunity and wrote all the datastructures from scratch. That was the hardest part of the program to get right. These are the other techniques I used to improve performance: * Using fstatat(2) with the parent directory's fd instead of lstat(2) with an absolute path. (10-15% performance increase) * Using statx(2) instead of fstatat. (perf showed fstatat running statx code in the kernel). (10% performance increase) * Using getdents(2) to get directory contents instead of opendir/readdir/closedir. (also around 10%) * Limiting inter-thread communication. I originally had fs-traversal results accumulated in a shared binary heap, but giving each thread a binary-heap and then merging them all at the end was faster. I couldn't find any information online about fstatat and statx being significantly faster than plain old stat, so maybe this info will help someone in the future.

Show HN: Open-source tool that writes Nvidia Triton Inference Glue code for you https://ift.tt/JhRfCba

Show HN: Open-source tool that writes Nvidia Triton Inference Glue code for you Triton Co-Pilot: A quick way to write glue code to make deploying with NVIDIA Triton Inference Server easier. It's a cool CLI tool that we created as part of an internal team hackathon. Earlier, deploying a model to Triton was very tough. You had to navigate through the documentation for the Python backend, figure out how to get your inputs and outputs right, write a bunch of glue code, create a config.pbtxt file with all the correct parameters, and then package everything up. It could easily take a couple of hours. But with Triton Co-Pilot, all that hassle is gone. Now, you just write your model logic, run a command, and Triton Co-Pilot does the rest. It automatically generates everything you need, uses AI models to configure inputs and outputs, and handles all the tedious parts. You get your Docker container ready to go in seconds. Check out our GitHub repository and see how much easier deploying to Triton can be! It would be great if you folks try it out and see if it works for you. reply https://ift.tt/hMme7bt July 11, 2024 at 04:24AM
