Show HN: Bulwark Passkey – A virtual Yubikey-like device for 2FA or WebAuthN Hey y'all, This is something I've been working on for a few months. It is a passkey system, similar to Apple Passkeys or a Yubikey, but it is entirely software based so you can sync credentials between devices. Passkeys (and FIDO devices in general) allow you to use public keys instead of passwords or codes to authenticate. For instance, you can just click "Approve" on the device/software instead of having to copy a code, and there are no passwords to phish. This is a new piece of tech, so website support for logins are still limited, but it can currently be used for 2FA anywhere a Yubikey can be used. Bulwark Passkey emulates the USB device in software, which allows you to sync credentials as well as copy them out. This is less secure than a dedicated hardware device, where credentials can never by copied or removed from the device, but it is much, much more secure and usable than passwords or one-time codes. Please take a look, and I appreciate any feedback you might have! https://bulwark.id November 29, 2022 at 10:41PM
Show HN: Jektex – Fast server side rendering of latex for Jekyll Hello! This is my first attempt of creating, publishing and maintaining my own package. I have a blog with something around 4000 latex expressions. Client side rendering using latex was super slow and some phones did not render it properly. I tried some KaTeX plugins for server side rendering but they were painfully slow (on my laptop it took more than 5 min to build). So I decided to learn some ruby and create latex rendering plugin by my self. So I created jektex. Jektex is a Jekyll plugin for fast server side cached LaTeX rendering, with support for macros and is very configurable. Now I can render y entire blog in 2 seconds on same laptop. I will be very happy for any feedback or advice. Have a nice day https://ift.tt/Vuq0TvI November 29, 2022 at 04:37AM

Show HN: General Task, a free task manager for builders (beta) Hello everyone! I left my job to start General Task a little over a year ago, and have been building a better free task manager with a small team. We aim to be the best place where one can find what’s next in their workday and we integrate with a number of different services to help do that. We’re still in the early stages of a beta, but so far you can: - Create/edit tasks with due dates, priorities, and folders - Drag tasks onto your calendar to block off time to do them (syncs with GCal) - Sync with Linear (JIRA coming soon) to see tasks assigned to you - Sync with Github to see your PRs - Integrate with Slack to make tasks directly from Slack What sets us apart? We know there are tons of task managers out there. We believe ours is different because it is tailor-made for engineers, with integrations for Github PRs, Linear and Slack. We also support dragging tasks onto your calendar, which is usually only found in premium paid products, while our consumer product is free and always will be. Our mission is to make knowledge workers more productive, and we believe the best way to do that is by focusing on software engineers and achieving mass adoption of a free consumer product before releasing a paid product for businesses. Let us know what you think! NOTE: We currently only support Google sign-in, sorry about that! We will be adding more login options soon. If you don't want to sign in with Google, you can see a quick 1 minute demo of our features here: https://youtu.be/NUOIH2On_Nw https://ift.tt/l7hm23P November 18, 2022 at 11:25PM

Show HN: At a Glance ESM Support for NPM Packages We've rolled out a feature for openbase.com that we think is a DX game changer for Node devs. Since the emergence of ECMA Script modules, it's been a continuous guessing game as to what kind of exports a package has. That's never really been discoverable without using a site like unpkg, or installing the package and inspecting package.json. Openbase now displays the ES Module support level (e.g. type of exports) on all of their package pages. We added this feature because our devs are some of the folks continually caught off guard by installing an NPM dependency only to find out it's ESM-only. If that's you too, or if the type of exports matter for your project, check out the package on Openbase first. https://openbase.com A few screenshots: - https://ift.tt/9AQ7vBZ - https://ift.tt/G60r2Lv - https://ift.tt/fLgZBbA November 19, 2022 at 01:17AM

Show HN: Flowchart-based planning tool to see the big picture (miro and asana) Hey HN, My dad, friend, and I have been working hard on building Twigflo, a flowchart-based project planning tool to help teams visualize their projects using the concept reverse planning. When I was a data consultant, I struggled keeping my team and clients aligned to a specific goal. Spreadsheets or equivalent tracking tools did a good job showing what to do but didn't explain why we were doing it and where we were going. So, like many of us here, we invested the time into building our own tool. We tried to make Twiglfo as goal-oriented and BIG PICTURE as possible. You and your team can set a goal and define how you get there. The key thing is everything you put on the canvas has to lead to the goal itself. If it cant be tied to the goal, no need to do it. We've had some early users (not friends or family) call this their preferred method of visualizing and communicating the big picture. You can easily see bottlenecks, dependencies, what can be done in parallel, etc. We believe its best place in your current workflow is before work gets started and when the need for alignment is most important. There are still clear areas where we can improve the experience but if these resonate with you, then give Twigflo a try. It's free to sign up. If you do, we currently only support desktop. Let me know if you have any feedback or questions! https://ift.tt/dhX4uzZ November 18, 2022 at 12:32AM

Show HN: Narrative BI – Turn marketing data into automated narratives Michael and Yury here – we're building a no-code analytics platform for growth teams that automatically generates actionable data insights. After working in the data space for many years, we realized there was still a huge gap in the marketing analytics market. Growth teams have so much marketing and advertising data, yet this siloed data is not actionable. The existing BI and search-driven analytics solutions are designed for data-savvy people. In our experience (previously built an NLP company called FriendlyData), non-technical people just don't know what questions to ask. So we decided to try a different approach: Narrative BI automatically generates a personalized feed of insights. You just need to connect your data sources (takes 2 min to set up), and you will get automated narratives, alerts, and reports in minutes. We currently support UA, GA4, Google Ads, and Facebook Ads, but many more integrations will be added soon. You can try it out for free and give feedback or roast it in the comments section. Just connect your data source, and you'll start getting narratives in 5 minutes. https://ift.tt/FRJc6kb November 16, 2022 at 11:53PM
Show HN: I Built a Gaming GeoGuessr My friend and I made a fully featured gaming geoguessr - complete with 360 degree panoramas, movement, leaderboards, and multiplayer. We had made a Fortnite geoguessr a while back, and although this was well received, our goal always was to bring the worlds of all games to the browser. A much harder task considering the scale and scope of many open world games. We had to make a bunch of tools to be able to achieve this. World of Warcraft alone took us roughly 3,000,000 images to do (and will likely need another 1,000,000 for Dragonflight once it releases). We are finally at a point where we are happy to release this into the wild and let people try it, although we are still working hard on adding all the games that are listed as coming soon.

Show HN: Dlna-cast, a command line tool to cast PC screen to DLNA devices dlna-cat is a cross-platform command-line tool that casts screen and media file to remote DLNA device. dlna-cast uses ffmpeg to capture screen and audio, then convert them into HLS streams which could be served by a simple HTTP server. The HLS url will be send to the selected device via uPnP protocol and then you can watch you screen on the remote device (smart TV, typically). This tool is supposed to be cross-platform but currently I don't have a Linux or MacOS device at hand so it can only run on Windows now. It won't be hard to support other platforms though, as there are no platform specific dependencies. HLS is chosen just because it is easy to implement. But the problem of HLS is its high latency (up to 5-10s or more) so it's definitely not for scenarios that require low latency (presentation for example). But as a trade-off the streaming quality exceeds a lot of software screen-casting solutions (Lebocast for example) that have been tested by myself, which make it pretty good to stream music or video playing from your PC to TV. https://ift.tt/36bcKtv November 14, 2022 at 11:07PM

Show HN: An API for CO₂ Removal Hi all, We're Fabienne and Ewan of Climacrux. Today we're proud to launch our latest project to try and make carbon dioxide removal as accessible as possible: CDR Platform [1]. In short: it’s an API to connect to a portfolio of carbon removers. You can purchase from as low as a single gram and select from both natural and technological removal methods. Longer: A couple of years ago we launched an alternative to carbon credits, Carbon Removed[2], designed for individuals to buy and subscribe to CDR. But we always had the nagging thought that there was more that could be done. CDR Platform is our foundation for that - a simple API to get prices and purchase (at the moment). Our plan is to become the Stripe of the carbon removal ecosystem, seamlessly connecting the supply to the demand. We’d love to hear your feedback. Do you see a use case for this and would you use it? What features have we missed? Do you understand what we’re doing and if not, what’s unclear? We’d love to hear from you.[3] Many thanks and happy hacking, Climacrux. P.s. If you are a carbon remover, send us your prices, life cycle analysis and some more information about your removal timeline. Our aim is to bring your services to a wider audience so you can focus on reducing our CO₂ levels. Thanks for your work!

Show HN: Generic dual-paradigm hooking mechanism Hi HN ! I am Alex, a tech enthusiast, I'm excited to show you a major iteration of my library for performing hooking in Python. I redesigned the whole project because it didn't not cover all my needs. I'm happy with the current iteration that I've written tests for and look forward to spending weeks and months using it in my projects. Python has a concept called Decorator [1] which is a function that takes another function and extends the behavior. In the following script, the timeit decorator is used to measure the execution time of the heavy_computation function: import time from functools import wraps def timeit(text): def deco(target): @wraps(target) def wrapper(*args, **kwargs): # execute and measure the target run time start_time = time.perf_counter() result = target(*args, **kwargs) total_time = time.perf_counter() - start_time # print elapsed time print(text.format(total=total_time)) return result return wrapper return deco @timeit(text="Done in {total:.3f} seconds !") def heavy_computation(a, b): time.sleep(2) # doing some heavy computation ! return a*b if __name__ == "__main__": result = heavy_computation(6, 9) print("Result:", result) Output: $ python -m test Done in 2.001 seconds ! Result: 54 Besides benchmarking, there are many other cool things that can be done with the Python decorator. For example, the Flask [2] and Bottle [3] web frameworks implement routing with decorators. While decorators are cool, it's worth mentioning that using a decorator is much more intuitive than writing its code. The code is entirely different depending on whether the decorator takes arguments or not. The following code performs the same task as the previous one, except it is more clear and intuitive: import time from hooking import on_enter def timeit(context, *args, **kwargs): # execute and measure the target run time start_time = time.perf_counter() context.result = context.target(*args, **kwargs) total_time = time.perf_counter() - start_time # print elapsed time text = context.config.get("text") # get 'text' from config data print(text.format(total=total_time)) context.target = None @on_enter(timeit, text="Done in {total:.3f} seconds !") def heavy_computation(a, b): time.sleep(2) # doing some heavy computation ! return a*b if __name__ == "__main__": result = heavy_computation(6, 9) print("Result:", result) Output: $ python -m test Done in 2.001 seconds ! Result: 54 The Hooking library used in the code above uses Python decorators to wrap, augment, and override functions and methods. It is a generic hooking [4] mechanism which is perfect for creating a plug-in mechanism for a project, performing benchmarking and debugging, implementing routing in a web framework, et cetera. Also, it is a dual paradigm hooking mechanism since it supports tight and loose coupling [5]. The previous code uses the tight coupling paradigm, that's why the timeit hook is directly tied to the target function. In loose coupling paradigm, targets functions and methods are tagged using a decorator, and hooks are bound to these tags. So when a target is called, the bound hooks are executed upstream or downstream. This paradigm is served by a class designed for pragmatic access via class methods [6]. This class can be easily subclassed to group tags by theme for example. Here is an example of the loose coupling paradigm: import time from hooking import H @H.tag def heavy_computation(a, b): print("heavy computation...") time.sleep(2) # doing some heavy computation ! return a*b def upstream_hook(context, *args, **kwargs): print("upstream hook...") def downstream_hook(context, *args, **kwargs): print("downstream hook...") # bind upstream_hook and downstream_hook to the "heavy_computation" tag H.wrap("heavy_computation", upstream_hook, downstream_hook) if __name__ == "__main__": result = heavy_computation(6, 9) print("Result:", result) Output: $ python -m test upstream hook... heavy computation... downstream hook... Result: 54 This library is available on PyPI and you can play with the examples [7] which are on the project's README. I would like to know what you think [8] of this project.

Show HN: textshader.com TLDR: Click the link to see some cool visualizations, refresh a few times for random examples, and try editing some of the code yourself. This is a small weekend project of mine inspired by shadertoy.com It's a static single-page site hosted on GitHub pages so the website design is pretty barebones. I'm not a web developer so I mainly wanted to create a Cool Thing with my free time and not have to learn tons of front-end to do it. I'd love to hear what people think about it and please post or send me any shaders you make! You can use the link button in the bottom right to share. I hope that this gets more people interested in shaders because GPU programming is a pretty different paradigm and learning it has made me a better software engineer even though my current job doesn't touch it. That said, textshader only runs normal Javascript on the CPU so think of it like a simplified sandbox and not the real thing. I'd highly recommend checking out shadertoy to level up to the real deal too! https://textshader.com November 7, 2022 at 10:02AM

Arguably I've spent too many months on this detail, but in addition to the standard DOM iteration, Unclutter uses a CSSOM iteration, patching of mobile styles, CSS word blocklists, and crowdsourced element selectors. Plus an animation system to move text to its "uncluttered" position. Also interesting might be the article "library", a lightweight read-it-later list. It uses screenshots instead of titles & thumbnails, and drag & drop to move articles around. And there's an integration with Hacker News, where every top-level comment with an article quote in it automatically gets converted into an annotation. https://ift.tt/pW12eQS November 5, 2022 at 01:01AM

Show HN: Crowd.dev – The open-source platform for community-led growth Hi everyone, after months of work we’re excited to show you crowd.dev - the open-source platform for community-led growth. We created crowd.dev with the belief that the future of business relies on thriving communities - particularly in the fast-growing open-source and developer space. Developers have increased buying power when it comes to the technologies their companies use, and the way to their hearts isn’t through paid ads or sales reps but through authentic community interactions. In other words, developer-focused companies (open-source, API, dev tools) need communities to grow. While crucial for every developer-first company, community building is complex and time-consuming work. The developer community tech stack is fragmented, and organizations are stuck managing endless platforms and working with incomplete data. Today, the term “community” gets used to describe everything from social media followers to online learning groups to DAOs. There has been a lot of hype around community, but the ability to turn it into real value and growth is still nascent. We see the need for a platform focussing solely on developer communities. “One-size-fits-all” doesn’t make sense when communities are different in terms of their members’ motivations, the platforms that they live on, or the business objectives that they should fulfill. Furthermore, we believe that an essential tool for open-source companies, as community management is, should be open-source itself. Since the beginning of 2022, several hundred companies have joined our closed beta, including some of the fastest growing open-source companies in the world, like Meilisearch, CrowdSec, or Dragonfly. Starting today, crowd.dev is also an open-source project. We’re looking forward to any feedback! https://ift.tt/PacI0MU October 31, 2022 at 08:37PM
