Show HN: Infracost (YC W21): Be proactive with your cloud costs https://bit.ly/45iAqeE

Show HN: Infracost (YC W21): Be proactive with your cloud costs Hi, we are Ali, Hassan, and Alistair, co-founders of Infracost (https://bit.ly/3q0dSel). Infracost helps engineers see the cost of each Terraform change before launching resources. When changes are made, it posts a comment with the cloud cost impact. For example, “you’ve added 2 instances and volumes, and change an instance type from medium to large, your bill will increase by 25% next month, from $1000 to $1250 per month”. We launched in February 2021 (https://bit.ly/3q0AHPl), and Infracost is now being actively used by over 3,000 companies. However, there is a shift happening in the cloud cost management space. New teams, called FinOps teams (a combination of "Finance" and "DevOps"), are being formed within companies to manage cloud costs. One of the first tasks assigned to these teams is to determine "who is using what" - that is, which teams, business units, products, etc. are spending the most on cloud. To accomplish this, they use tags. Tags are labels that all cloud resources should have and are key-value pairs. For example, a server could be tagged with: product=HackerNews; environment=production; team=blueTeam. So if resources are not tagged properly, then you can’t tell who is using what. However, FinOps teams face challenges because their tools are reactive. These tools begin by analyzing cloud bills and providing visibility of tags from there. This means that they are looking at resources that are already running in production and costing money. A customer recently shared, “I want all resources to be properly tagged. But if they are not, I would rather a resource not be tagged at all than be tagged incorrectly.” My "aha" moment! FinOps teams can define a tagging policy that can be validated in CI/CD before resources are launched. This is important because if code is shipped with the wrong tags, FinOps teams will have to fight for sprint time to fix them. Even if you shut down an untagged resource directly in the cloud, the next time Terraform runs, the resource will launch again with no tag. You need to fix the issue at its root. I’d love your feedback on our solution to the tagging problem. You define your tag key-value policy in our SaaS product, and Infracost checks all Terraform resources per change. If anything fails the policy, it posts a comment with the details of which resources need tags, and what the allowed values are. Once fixed, it will let the code be shipped to production. Try it out by going to https://bit.ly/3qnXOZw, setting up with the GitHub app or GitLab app, and defining your tagging policy. It will then scan your repository and inform you of any missing tags and their file and line number. You can use the free trial, but if you need more time, please message me and I’ll extend it for you. I would also love to hear how others ensure that the correct tag keys and values are applied to all resources, and whether this is done proactively or reactively. Additionally, I would be interested in hearing about any lessons learned in the process. Cheers August 9, 2023 at 02:01PM

Show HN: Social Bellow – AI-Powered Interactive Companion https://bit.ly/45jyjal

Show HN: Social Bellow – AI-Powered Interactive Companion Greetings HN, My name is Edgar and I've created Social Bellow, an AI chat companion. Before this I spent close to a decade working on games with Grumpyface Studios, working closely with Cartoon Network as well as managing my own business. I've built Social Bellow out of the need to manage prompts and eliminate the repetitive task of copying and pasting the same prompts. Storing prompts has the added advantage of providing Large Language Models (LLMs) with more context, thereby facilitating structured content responses. Moreover, I saw the necessity for a tool that could maintain the context window during conversations with the LLMs. Social Bellow was built using AWS Amplify, NextJS, and the help of Vercel to do the streaming. Figma has also helped tremendously in the creation of the project. Having a workflow of Figma, Amplify Studio, and Git continuous deployment has cut down on the time to publish a change. Social Bellow is free to use with OpenAI GPT-3.5 Turbo with a token allowance of 50,000 tokens a month. I've just launched this so you'd be one of the first to try it out. Thank you for the feedback and helping improve the application! https://bit.ly/3QES1cu August 9, 2023 at 09:10AM

Show HN: MagicQuit – closes apps when you don't use them anymore (free) https://bit.ly/3DMEc46

Show HN: MagicQuit – closes apps when you don't use them anymore (free) I often end up having 15+ applications open in my Dock. And, unfortunately, I tend to never close them. While Arc Browser does a great job for browser tabs, I didn’t find any fully satisfying solution for MacOS. One used way too much power and the other one would have taken quite some time to set it up. So instead I decided to develop an app which took x times more of my free time. MagicQuit is entirely free, open source, 100% offline and closes apps that you haven’t been using in the last 12 hours (customizable). Feature-wise I wanted to keep it as clean and simple as possible. It also uses nearly ~0% of cpu usage. Give it a try if you’re a Mac user and also having the same issue with many open applications: https://bit.ly/3KybkAp https://bit.ly/3KybkAp August 9, 2023 at 12:48PM

Show HN: The Population Project https://bit.ly/44Yd91L

Show HN: The Population Project Two years ago, I turned 50. After a successful career as an entrepreneur, a business angel and a novelist, I set out to start a philanthropic venture under the following constraints: - it had to be global. - it had to be beautiful (in my eyes, at least). - it had to be technology and stats driven. I decided I would try to list the full name and date of birth of all humans alive. While some may find the concept pointless, I immediately knew I had struck gold: - it was global and incredibly hard. - it had an almost artistic quality to it, like an ever-changing installation. - as a libertarian, I resent that states conduct censuses and then sit on the data. - One billion people in the world aren't officially registered. At least someone would acknowledge their existence. I created a non-profit called The Population Project. I would never make a dime off it, but at least my costs would be tax-deductible. I then started researching lists of names online. I quickly adopted two principles. First I would collect a minimal set of information : full name, birth date, and birth place. Second, I would only scrape public information, i.e. nothing behind a password. After a few months, I realized I needed help from more experienced developers. I chose to work on 4D, a platform I had used in the past to develop my company's information system. It was a tough choice: 4D is not a leading player in the back-end world, but I figured the growth of API tooling would make language choice less critical. The first iteration of our database was frustrating - way too slow to publish a website. I learned the power of incremental change, with each marginal improvement saving you a few percent of speed or space. I also got to implement concepts I had heard about but never implemented, such as mirroring, partitioning, or hash-indexing. Then I hired a team of six data processors in Madagascar who clean up and process the lists found online. Lots of Python and Excel macros in their day-to-day. I have instilled in them an obsession with quality. A bad record will sit in our base forever. After trying dozens of softwares, we've settled on Adobe Acrobat and Octoparse. The final piece was the website. I lucked out in finding a strong team in Romania. They build with Next.js and deploy on Vercel. I gave them Wikipedia as the model to aim for. We/they haven't been able to match Wikipedia's simplicity. Our pages are too heavy. But I find the site user-friendly, pleasing to the eye and reasonably fast. We can and we will do better. A word about privacy. Some people complain that because it publishes names and DOBs, the Population Project infringes on their privacy. We obviously don't see it that way. - All our info is public. That DOB you find on the site is probably in the voter list of your state, a list that anyone can request or plainfully download. - The info we publish is minimal. Basically, we say that you exist. No one will find anything about your race, religion, sexual preferences, job or income. - We have adopted Wikipedia's privacy policy. We do not record your IP, unless you create or edit a record. - We're using Matomo for our Analytics. Great stuff. It's not free but they do not use your data like GA. Why am I telling you all this? From the beginning, I've envisioned a three-step process: 1) Build the database and populate it with millions of Western profiles. 2) Launch the site, where anybody can create or edit records and share them with their family. 3) When we've reached critical mass (1B records?), start making deals with NGOs and governments, and venture into other alphabets. We have just completed step 1. Step 2 is daunting as hell. I have grown a business but I have never grown a website. While I am ready to spend a bit of money on PR or SEO, I am not delusional: to reach the level of success we have in mind, we need this thing to go (somewhat) viral. How do you do that? https://bit.ly/453p8LC August 7, 2023 at 04:46PM

Show HN: A social media site for reviewing albums, movies, books, and podcasts https://bit.ly/47pxi2E

Show HN: A social media site for reviewing albums, movies, books, and podcasts I’ve been working on a social media web app for reviewing works of entertainment with the hopes to compete against Goodreads and Letterboxd. I started working on this two and a half years ago and it has taught me a lot about full stack development, from Vue, and REST APIs, to hosting with AWS. It’s still very much so a work in progress, but it’s functional and I’d love any feedback I can get. I know other options exist, but I couldn’t find one that I like that had all of the different mediums, and I’d rather have them all in one place. Likewise didn’t give me enough freedom with rating, and seemed more focused on algorithm generated suggestions. Usage : A lot of functionality requires a login, so I created this guest account for you guys to use: username: showhnguest password: hackernews23 If you wind up liking it enough to create an account, feel free to invite your friends. https://bit.ly/44UdLWe August 8, 2023 at 01:38PM

Show HN: Building an Audio Journaling App – Looking for Community Insights https://bit.ly/44WUuTX

Show HN: Building an Audio Journaling App – Looking for Community Insights I am a product designer by profession, and recently, I ventured into coding and started developing applications. Today, I'm excited to share a project I've been passionately working on. The concept is a voice-activated journal: just voice-record your thoughts, and the app will transcribe them into text. I built this to help those like me who struggle to build a journaling habit. Also has features that encourage habbit building like a streak/tracker and a threshold marker encouraging you to record a minimum amount. I used OpneAI Whisper to power the transcriptions which means you can record journals in most common languages and it will transcribe it accurately. I am hoping to get feedback from all of you: Would you use this? If Yes, how often? If No, What would hold you back? Would you pay for this? If yes: How much, If no: what if added would make you want to pay for it? Screenshots: https://bit.ly/450bZ5R https://bit.ly/45gv2ZB August 8, 2023 at 08:15AM

Show HN: I created an app to transfer files from my PC to any device wirelessly https://bit.ly/44Ypweh

Show HN: I created an app to transfer files from my PC to any device wirelessly I found transferring images from my PC to my phone very tedious. Using Whatsapp and other such apps reduced image quality and had limitations on the file size. Using online file transfer solutions were too slow for my taste. Hence, I created a desktop app to send all sorts of files - images, PDFs, lengthy videos, etc. to any device connected to the same Wi-Fi network. You also don't need to download a separate mobile app. There's only 3 steps involved - select your files, scan a QR code, download your files. You can download it now for free via https://bit.ly/44VNIy4 August 6, 2023 at 07:53PM
