New top story on Hacker News: Reciprocal Approximation with 1 Subtraction

Reciprocal Approximation with 1 Subtraction
7 by mbitsnbites | 3 comments on Hacker News.
Today's find: You can get a floating-point approximation of 1/x that's accurate to 3 bits with a single integer subtraction instruction. float fast_reciprocal(float x) { unsigned i = *(unsigned *) &x; i = 0x7effffffU - i; return *(float *) &i; } The magic number 0x7effffff accomplishes two things: 1) The exponent is calculated as 253-e, which effectively negates the exponent and subtracts 1. 2) The mantissa is approximated as a 1st order polynomial in the interval [1, 2). Interesting, but perhaps not very useful (as most CPU:s have more accurate reciprocal approximations these days).

Show HN: Shop Clothes with Models That Match Your Body Shape
4 by Deekshana_Reddy | 1 comments on Hacker News.
This is one of those fix a problem you can’t ignore projects. Like most online shoppers, I often found myself frustrated: clothes look great on models but disappoint when I try them on. It’s not the clothes, it’s the body shape mismatch. So, I spent the last few months building TheBodyMatch, a platform where clothes are showcased on models who share your body shape. You get a more relatable and confident shopping experience because seeing is believing, especially when the model reflects you. It’s still early days. Think of this as a beta where feedback is gold. I’d love for you to try it out here: www.thebodymatch.com and share your thoughts. Is this the future of online fashion? I hope so.

Hi HN! I’m a professional runner and programmer, and I built *Run10K Trainer*, the app I wish I had when I started training. It’s a web and mobile app that generates personalized plans for 10K races, tailored to your schedule, experience level, and race date. After months of development, I’d love your feedback to help make it even better for runners everywhere. Does this sound like something you’d use?

Show HN: myphotos.site – Google photos to a website in 60 seconds
7 by gabigrin | 2 comments on Hacker News.
Hey HN! My friend and I love taking pictures on our phones, and we were looking for a super simple way to share them with the world. Google Photos albums are nice, but the result isn't slick enough and lacks customization options (embed, custom domain). That's why we built myphotos.site - a micro SaaS that allows anyone to create a slick, minimal gallery website from Google Photos. Galleries can be iframe-embedded for those looking for full customization. One thing we haven't solved yet - many Google Photos users (myself included) do not have images pre-organized in albums, so the fact that technically it takes 60 seconds to build a website doesn't take into account that you have to spend time picking the right images. Would love to some feedback/ideas from hobbyist photographers here!

Show HN: A ready-to-adapt email marketing sequences database
9 by davidbff | 3 comments on Hacker News.
Hey HN, as an email marketer for the past 4 years, I’ve built sequences that reach millions of inboxes every month. But whenever I start a new project—or when a company reaches out for help—it was always almost back to square one: researching from scratch, especially when entering an unfamiliar industry. Really Good Emails and similar resources are awesome, and I use some of them every now and then. But to me, they lack that strategic part of email marketing. So, a couple of months ago, I started building a database of email sequences, which now has examples from 80+ companies and over 330+ categorized and sequenced emails. It’s designed to help non-marketers, solo founders, and busy teams create better email campaigns without starting from scratch. I’d love to hear your thoughts or any suggestions for improvement. Thanks for taking a look!

Show HN: Nova JavaScript Engine
11 by aapoalas | 0 comments on Hacker News.
We're building a different kind of JavaScript engine, based on data-oriented design and willingness to try something quite out of left field. This is most concretely visible in our major architectural choices: 1. All data allocated on the JavaScript heap is placed into a type-specific vector. Numbers go into the numbers vector, strings into the strings vector, and so on. 2. All heap references are type-discriminated indexes: A heap number is identified by its discriminant value and the index to which it points to in the numbers vector. 3. Objects are also split up into object kind -specific vectors. Ordinary objects go into one vector, Arrays go into another, DataViews into yet another, and so on. 4. Unordinary objects' heap data does not contain ordinary object data but instead they contain an optional index to the ordinary objects vector. 5. Objects are aggressively split into parts to avoid common use-cases having to reading parts that are known to be unused. If this sounds interesting, I've written a few blog posts on the internals of Nova over in our blog, you can jump into that here: https://ift.tt/rcnJkNF

Ask HN: Would you recommend a framework laptop
2 by ramon156 | 0 comments on Hacker News.
It's that time of my life where I need to find a good work laptop. With the prices that laptops go for I'd rather not impulse buy and (maybe) regret my decision. My last purchase was a Vivobook S(15?), and even with the discount I regret it to this day. It didn't even run Windows 10, and I had no time to look for another one as my uni courses already started. 700 euros for a raspberry-grade CPU that sucked the battery dry in less than an hour. The DIY option from Framework seems very intriguing. The customizing part seems rather cheap (I could get extra accessories in case I change my mind for ~10 euros per piece). My question is if anyone has experience with them and would recommend them, as I want to avoid another flop.

13 by dirkc | 10 comments on Hacker News.
I didn’t have a doorbell before (multiple reasons) and my house feels unwelcoming without one. So I built a doorbell app that uses a QR code - visitors scan the QR code to ring the doorbell and I get notified on my phone. Here is an example of the QR code I have on my door. You can scan it and say hello: https://ift.tt/nCqRMso This was also a great excuse to build my first app for Android and iPhone. I’d love to get some feedback before I spend more time polishing the app. Please try it out and feel free to ask me any questions! No logins or accounts needed.

Show HN: MonsterWriter – Write a thesis, post, or organize notes
11 by WolfOliver | 3 comments on Hacker News.
Hello HN, in 2017 I started a project that would become MonsterWriter. First envisioned as a semi-structured wiki it became a writing application specialized for scientific content. It is a perfect tool if you write your thesis. While it is focused on technical content, you can still see the knowledge management spirit in it. One or two years ago, my wife joined me in my efforts and redesigned the whole project and we recently released it as MonsterWriter2. To celebrate this milestone we are giving away free lifetime licenses for the Desktop version (till Apr 28). Just use the promo code "gu0ho4q" for a 100% discount. You can find detailed instructions here: https://ift.tt/57zZcQJ You can also find a short introduction video to the app on YouTube: https://www.youtube.com/watch?v=vR8i-EY_UBk We are happy to receive any kind of feedback!

Show HN: A universal Helm Chart for deploying applications into K8s/OpenShift
8 by nixys_nxs | 4 comments on Hacker News.
Hey HN! We wanted to share with you nxs-universal-chart - our open-sourced universal Helm chart. You can use it to deploy any of your applications into Kubernetes/OpenShift and other orchestrators compatible with native Kubernetes API. Our team regularly faced the need to create almost identical charts, so when we had 14 identical microservices in one project, we came up with a chart format that essentially became a prototype of nxs-universal-chart. It turned out to be more relevant than we even thought! When we needed to prepare CI/CD for 60 almost identical projects for a customer, we reduced the preparation time for release from 6 hours to 1. Basically, that’s how the idea of nxs-universal-chart became a real thing that everyone can use now! The main advantages of such chart that we would like to highlight: -Reducing time to prepare deployment -You’re able to generate any manifests you may need -It compatible with multiple versions of k8s -Ability to use go-templates as your values In the latest release we’ve added a few features like cert-manager custom resources support! Any other information and details you can find on GitHub: https://ift.tt/nZswj8l We’re really looking forward to improving our universal-chart so we’d love to see any feedback, contributions or report any issues you encounter! Please join our chat in telegram if you want to discuss something about this repo or ask any questions: https://ift.tt/UVMreGh

When you're a tiny team of developers working on something beyond MVP level and beyond heroku — managing your CI, deployments/rollbacks, DBs etc. looks like a nightmare to me without Devops expertise. I want to understand what kind of challenges you all are facing with regards to this. And any tools, practices, you’ll are using to reduce this pain? Ex- How do you deploy resources? How do you define architecture? How do you manage your environments, observability?, etc.
