Show HN: Forth – Rethinking (and improving) News Hi HN -- After a thread a couple of weeks ago (https://bit.ly/3GoE2Qw) got more attention than I expected, and someone even suggested doing a Show HN (thanks wanderingmind)-- so, here goes: We're building a network of local journalists, along with others in national verticals. Our incentive structure exists in a way to promote news people want to come back to read, not clickbait headlines, divisive or anger driving hot takes, or lowest common denominator coverage. All geared to 18-34 year olds, who are less likely to consume local news in the traditional forms, like subscribing to a local paper or watching broadcast TV. It's still early stages; but we're proving out the concept. Newsrooms are infamously understaffed, so asking them to take on another platform is usually a nonstarter. Instead, we offer free, proprietary communication tools to help the staff communicate (https://bit.ly/3Gnqvcc) and that syndicates updates out automatically. As we're onboarding traditional newsroom partners, we're also pushing forward with college students (see Ithaca, NY: https://bit.ly/3GwBT5J) and also automatically publishing White House Pool Reports (https://bit.ly/3Egss8l) which are public, but difficult to obtain if you aren't in the media. I'd love to hear what you think. And as an aside/shameless plug, if you work for a newsroom or cover local news, please reach out -- we'd love to have you on board -- jared at nillium dot com.

Show HN: LED Website Indicator – an LED lights up when someone visits your site https://bit.ly/3b9oXE0

Show HN: LED Website Indicator – an LED lights up when someone visits your site Recently while looking for coding work I connected an LED to my resume site so that I would have instant feedback in the form of a visual notification whenever anyone visited. People seemed to like the idea when I wrote about it on my blog, so I have made this into a free service. Using ESP8266, my own hosted MQTT broker and WordPress plugin. If you want to try it out, I have the instructions over at https://bit.ly/3m7mZdN - see the "learn" page. All you need is a spare ESP8266 module and a WordPress site. I'm concentrating on WordPress for now, but it should be relatively simple to send MQTT messages from other types of websites. If there is enough interest I plan to do this as a pre-programmed product, with an RGB LED and support for multiple websites. I know you can set this up yourself with Node-Red or Adafruit but I'm going for a very focused product which does one thing well, and is super simple to set up. October 23, 2021 at 07:57PM

Show HN: I created a tool to schedule HTTP requests In my last project, I was struggling to create and monitor cron jobs. So, instead of creating hundreds of standalone scrips and executing them with cron, I decided to turn those scripts into multiple endpoints. Next, I created a single service that I could schedule HTTP requests to those endpoints and monitor its execution. No more scripts, now everything is endpoints that I can run manually at any time I turned this scheduler service into a Micro-SaaS so you don't have to build it yourself: beew.io I know you can Schedule HTTP requests with Zapier but come on... I will not pay 50 bucks for that hahahaha btw, feedbacks are welcome. https://bit.ly/3GdxKmU October 22, 2021 at 06:38PM

Show HN: Semgrep App https://bit.ly/3EcOusN

Show HN: Semgrep App https://bit.ly/3GfyJTo Hi! I work on Semgrep, an open-source project (discussed on HN previously [0][1)]. We’re one of those companies that maintain an OSS tool and a web app, and then monetize by selling enterprise features on said web app. Our free web app just went through a major revamp (sort of like a v1.0 release) so this feels like the perfect time to share and hear what the HN crowd thinks! Let me start with some backstory on Semgrep. Our team, r2c, has been experimenting with various ways to help organizations step up their application security game. One of our earliest experiments was Bento, a wrapper around multiple existing linters to help people configure various tools like ESLint and Bandit in one go. The bottleneck with a tool like this was, of course, interfacing with more and more tools. I had previously worked on a similar project called coala[2] which got all the way up to 78 analyzers covering 54 languages, until the project ground to a halt over the maintenance burden of all that. One of our team members at r2c came up with a novel approach to this problem: he suggested reusing some of his old work on Coccinelle[3] and later Sgrep[4], which were tools to search parsed syntax trees of various languages. Conceptually this meant that while Bento and coala could standardize the command-line interface, the configuration syntax, and file targeting logic of linters, now we could also standardize the core linting logic. Extending Bento with linting rules using this pattern language proved to be so easy that we rather just reimplemented the existing linters with it. And thus, Semgrep was born specifically to scan code with these pattern definitions, and there was no longer a need for Bento. Our rule registry[5] now contains over 1,500 rule definitions in this standardized linter rule definition language, across 20 languages. And this leads us to our web app. Early adopters of Semgrep encountered problems rolling out the CLI tool across their organization. Their key needs: scanning hundreds of repos, reviewing all their scan results, deploying custom organization-internal rules across them, and avoiding backlash from developers during all that. We also made the unorthodox decision to start with a ground rule that we never ever want to have access to the source code of our customers. These needs and rules guided our web app’s feature set, which ended up being: provisioning CI jobs on repositories, centrally configuring which rules should block builds or notify people, sending notifications via PR comments/Slack/email, and displaying the list of all findings, along with some analytics. As for today, we just launched a major release of Semgrep App, which cuts down on the complexity that built up in our original implementation, and we also tried to expand the problem space our app tackles all the way through remediating issues on the web UI. You can read more about these recent changes at https://bit.ly/2ZfH3So And as for the future, two main areas of interest are 1) intelligently selecting all the right Semgrep Registry rules for a given project and 2) creating a smooth workflow for organizations to collaboratively maintain their own set of internal Semgrep rules. Please check out the app we built at https://bit.ly/3GfyJTo , and let us know what you think! I’ll be hanging out in the comments as one of the engineers who built the app, but our CEO (ievans) is also ready to answer questions, and the rest of the team will surely be lurking here as well.

Show HN: Stable Reminders – never miss a business filing deadline again https://bit.ly/3BZZby3

Show HN: Stable Reminders – never miss a business filing deadline again Hi all! We’re Collin and Sarah from Stable — a virtual address + mailbox for business. Today we’re excited to share that Stable is launching Stable Reminders (https://bit.ly/3aX8dA4)! What are Stable Reminders? Stable Reminders are email notifications sent directly to your inbox before important federal and state filings are due. These reminders are customized to your entity type and state(s) you've registered to do business in. It’s nothing fancy, just reminders, and all for free. Why are we launching this? We have digitized a lot of physical mail — our core product is a virtual address + mailbox for business. Throughout this, we’ve been consistently surprised by the number of businesses that get notified and fined for missed filing deadlines via physical mail. We think it’s anxiety-inducing to receive unknown mail from a government agency, frustrating to pay fines for simple oversight, and generally outdated to receive physical mail in the first place. We built Stable Reminders to make tracking and acting on filing deadlines a better experience! With Stable Reminders, we hope your business can avoid penalties & late fees imposed by federal and state governments, ensure that good standing is maintained, and gain peace of mind + instill confidence that filing deadlines will be met (especially if you aren’t relying on a corporate lawyer). Currently support jurisdictions: Federal, Delaware, California (If you’d like to see support for other jurisdictions please leave a comment or email us at collin.pham@useStable.com) What do you think? Does this sound useful to you? If it does, you can sign up with your email here (https://bit.ly/3aX8dA4). If it doesn’t, we’d love to hear why in the comments. If you’d like to learn more or have any questions, leave a comment or shoot us an email at collin.pham@useStable.com October 20, 2021 at 05:30PM

Show HN: Datree (YC W20): Prevent K8s misconfigurations from reaching production https://bit.ly/2Z6Hz5e

Show HN: Datree (YC W20): Prevent K8s misconfigurations from reaching production When I was an Engineering Manager of Infrastructure at ironSource (NASDAQ:IS) for 400 developers, a developer made a mistake, causing a misconfiguration to reach production, which caused major problems for the company's infrastructure. Mistakes happen all the time - you learn from them and hope to never make them again. But how can we prevent a production issue from recurring, or, how about a bigger challenge — how can you prevent the next one from the get-go? In our case, we tried sending emails to our devs, writing Wikis, and hosting meetups and live sessions to educate our developers, but I felt that it just wasn’t driving the message home. How can developers be expected to remember to configure a liveness probe or to put a memory limit in place for their Kubernetes workload when there are so many things that a dev must remember? Infra just isn’t their primary focus. Today, organizations want to delegate infra-as-code responsibilities to developers, but face a dilemma — even a small misconfiguration can cause major production issues. Some companies lock up infra changes and require ops teams to review all changes, which frustrates both sides. Developers want to ship features without waiting for infra. And infra teams don't want to “babysit” developers by reviewing config files all day long, essentially acting as human debuggers for misconfigurations. That’s why I teamed up with Eyar Zilberman to found Datree. Our mission is to help engineering teams prevent Kubernetes misconfigurations from reaching production. We believe that providing guardrails to developers protects their infra changes and frees up DevOps teams to focus on what matters most. Datree provides a CLI tool (https://bit.ly/3phXqIQ) that runs automated policy checks against your Kubernetes manifests and Helm charts, identifies any misconfigurations within, and suggests how to fix them. The tool comes with dozens of preset, best-practice rules covering the most common mistakes that could affect your production. In addition, you can write custom rules for your policy. Our built-in rules are based on hundreds of Kubernetes post-mortems to ensure the prevention of issues such as resource limits/requests (MEM/CPU), liveness and readiness probes, labels on resources, Kubernetes schema validation, API version deprecation, and more. Datree comes with a centralized policy dashboard enabling the infra team to dynamically configure rules that run on dev computers during the development phase, as well as within the CI/CD process. This central control point propagates policy checks automatically to all developers/machines in your company. We initially launched Datree as a general purpose policy engine (see our YC Launch https://bit.ly/2IEBDo8) in which you could configure all sorts of rules, but the market drove our focus toward infrastructure-as-code and, more specifically, Kubernetes, one of the most painful points of friction between developers and infrastructure teams. When we adjusted to a Kubernetes-focused product, we pivoted our top-down sales-driven model to a wholly new bottom-up adoption-driven model focused on the user. Our new dev tool is self-served and open-source. Hundreds of companies are using it to prevent Kubernetes misconfigurations and, in turn, are helping the tool improve by opening issues and submitting pull requests on GitHub. Today we are a “product-led growth” company, which is a relatively new business methodology centered on user adoption driving product demand toward monetization. Our product is well suited for self-evaluation and immediate value delivery. No more demo calls — just 2 quick steps to try the product yourself! TechWorld with Nana did a deep technical review of our product, which can be viewed at https://www.youtube.com/watch?v=hgUfH9Ab258. We look forward to hearing your feedback and answering any questions you may have. Thank you :) October 19, 2021 at 04:04PM

Show HN: mybf.io - platform for software reviews with social network aspect Hi! Recently I've launched - mybfio.io - platform for software reviews with social network aspect. Prehistory Many great system are already in place that allow people to search and rate software products, including the site I am publishing this post on. However I have always felt that those systems are not specifically centered around product/software development lifecycle (releases, real users feedback over a product entire lifetime, so on) and often too broad or not designed specifically for that type of work, which is ok. Why? As an opensource author I would like to have constant real users feedback, not necessarily tied only to bugs and feature requests. And even if my project is not that big and not that promoted I still want my voice will be heard among myriads of other projects and to gain my own community. Who? Opensource authors seeking to build community around products they maintain Users seeking for relevant and well maintained software to fit best theirs needs What? Welcome mybfi.io, see the "Principles" article on mybfi.io site - https://bit.ly/3BMwip4 explaining some of those principles in more details. PS The mybfio service is still in active development, things might change, but any feedback is valuable. October 14, 2021 at 09:58PM

Show HN: OtterTune – Automated Database Tuning Service for RDS MySQL/Postgres https://bit.ly/2YTVFXG

Show HN: OtterTune – Automated Database Tuning Service for RDS MySQL/Postgres Yo. OtterTune is a database optimization service. It uses machine learning to automatically tune your MySQL and Postgres configuration (i.e., RDS parameter groups) to improve performance and reduce costs. It does this by only looking at your database's runtime metrics (e.g., INNODB_METRICS, pg_stat_database, CloudWatch). We don't need to examine sensitive queries or user tables. We spun this project out of my research group at Carnegie Mellon University in 2020. This week we've announced that OtterTune is now available to the public. We are offering everyone a starter account to try it out on their Postgres RDS or MySQL RDS databases (all versions, AWS US AZs only). We have seen OtterTune achieve 2-4x performance improvements and 50% cost reductions for these databases compared to using Amazon's default RDS configuration. I am happy to answer any questions that you may have about how OtterTune works here. -- Andy ================ More Info: * 5min Demo Video: https://bit.ly/3FMAIym * Free Account Sign-up: https://bit.ly/3DGPdSv October 14, 2021 at 07:54PM

Show HN: HTML Planet for Kids – A HTML and CSS Course for Children https://bit.ly/3v3irIk

Show HN: HTML Planet for Kids – A HTML and CSS Course for Children Hi HN, We are Matjaz (that’s me) and Benjamin - a father & son team - from HTML Planet for Kids (https://bit.ly/3v5TsUI), an online space where children learn and create with HTML & CSS. I’m the author of Pinegrow Web Editor (launched on HN seven years ago) and Ben is a 11 year old boy full of creativity and ingenuity. In early 2020 our family embarking on a journey around the world. Thanks to the Covid pandemic we immediately got stuck at our first destination. With time saved on not traveling around, Ben and I finished our Maths lessons early and had some extra time to do a project together. We did research on existing HTML & CSS courses and discovered that all teach HTML & CSS exclusively through coding, and after the course is done, they offer no follow-up to engage kids in using their newly acquired skills. We decided to take a month off and create a HTML & CSS course for children, based on the simplified online version of our web editor software. That was more than a year ago :) The quick one month project turned into a year of work on creating the course structure, designing and recording the adventures, improving the website editor, testing… But, every evening, we showed up for work and step by step, got HTML Planet for Kids ready for release. It has 60+ interactive lessons and projects that teach children enough HTML & CSS to be able to create simple websites. Our visual editor lets children jump straight into using HTML & CSS, without having to memorize the code syntax and property names. Along the way, they get naturally familiar with coding and can start using the built-in code editor. Completing the lessons is just the beginning. Kids then use their skills to create projects (websites, experiments, toys) with HTML Planet. We plan to run monthly challenges and showcases to keep children engaged. If you are a parent, caretaker or teacher - or just feel like going on a space adventure, visit HTML Planet for Kids and take it for a spin. No registration is needed to do the first ten adventures. Looking forward to your feedback! Ben & Matjaz https://bit.ly/3v5TsUI October 12, 2021 at 06:46PM
