Show HN: Google hijacking search from GitHub, Twitter, others I couldn't find any relevant info about this. Maybe I'm part of some new Chrome experiment, or just very bad at searching. Here's what it looks like: https://ift.tt/psqrf8z I opened a new Chrome tab just now, typed GitHub in the address bar. Opened the top suggested repository I'm checking frequently, and then used the GitHub search input box. As GitHub search results loaded, on the right side of the Chrome address bar I noticed a new, and colorful G icon. Animating and distracting, the icon expanded into a pretty big inline notification saying "See more search results". After a few seconds it animated and minimized itself back to the G icon. Clicking the icon opens a right side panel with Google results of my GitHub query. I then tried to search for something via the Chrome address bar. Without clicking on any of the results, I used the address bar again to open Twitter's home page (typing twit...

We make it easy to query any blockchain with SQL, analyze it in notebooks, and embed the data in your app with our API. You can answer questions like: how many people that used Uniswap also have an ENS / .eth address? I know a lot of people here hate crypto. I get it. There's a lot of bullshit and scams in crypto. I'm personally drawn to it because a lot of financial applications suck and crypto provides a set of open source tools to build better ones.

Would love feedback and/or problems you encounter. I used both a Leica BLK 360 and Matterport Pro 2 to do the scanning and the Matterport SDK for the web viewer. Matterport's web display with Three.js has been the most accessible to a wide audience in the past (previous iterations are in Unity and Unreal, but difficult to download over slower connections). I've been interviewing social studies teachers around the 6th grade level to create teaching materials as well, and these along with other monuments that I've scanned at Giza are up at https://giza.mused.org/ Cheers from Cairo--and thanks for any feedback. https://ift.tt/UYpMgdm October 27, 2022 at 06:31PM

Show HN: Klipit.in – Online clipboard, quickly share data across devices Hello, wanted to share about my new project called Klipit. How do you quickly share data between devices? Here's what most people do – - Send it to someone on WhatsApp or other messaging service. - Email it to themselves. - Use a note taking application like Google Keep, Apple Notes or OneNote (my preferred way until now). All of these require you to already have those services logged into on both the devices. Logging into any service on a new device these days is a tedious process involving 2-factor authentication. What if there was a quick way to share data between devices? One that did not require any logins or installing any apps? Starting with this thought, I built Klipit.in. An online clipboard to share data quickly between devices. You get an instant online clipboard with a unique link. No need to create any account. You can paste any data to this clipboard and simply open the link on another device. No...

All of a sudden, 5-10 mins went by and I hadn't done anything yet. To solve this I tried setting timers, counting to myself, and a number of other ways. I realized the only way that I could consistently take a shorter shower is if something told me what I was suppos...

Show HN: mirrord – run your local code in the context of your cloud environment Hey everyone, I’m Eyal, co-founder and CTO of MetalBear, the company behind mirrord. We’ve recently released version 3.0 of mirrord - it’s the first version of the product that we believe can provide daily value for backend developers. mirrord is a free, open-source (MIT) product that cuts your development loops by making it easier and faster for your local code to “meet” your cloud environment. mirrord lets you “plug” your local process into your Kubernetes cluster. When you run your process with mirrord, it completely wraps your process in the context of the corresponding service on your cluster - it essentially proxies all of your process’ input/output to the remote pod, from network traffic to file access to environment variables, so that you can keep running your process from the familiar comfort of your local environment, but with input, configuration, and state from the cloud. While mirrord can be us...

Show HN: An investment forum where everyone manages a $1M imaginary portfolio Hi there! Made LongTermBoard.com as a Jr. FE engineer fresh from leaving the investment field but still in love with it. Back then, I'd read articles on investment forums and wanted a quick way to determine if I should spend time reading the analysis. I wanted a quick way to determine if the author is a good investor. LongTermBoard solves this by making it easy to view the competency of the author by seeing his investment performance of his profile. It's long-only for now, as the goal is to look for great long-term businesses to invest in. It ain't perfect as its a controlled investment environment, but my hope is that over the longer term, the portfolio performance should be a good proxy. It's super rough now, so hope it doesn't break. https://ift.tt/6VLUaq0 October 23, 2022 at 08:46PM

I wanted to have a way to share my photos, videos, documents etc from my phone directly to my MBP, without having to upload anything to the 'cloud' or some messaging app. Those ways tend to be less secure and fairly slow.

Building and deploying it has been a great learning experience, and in that spirit I'd be grateful for any thoughts or suggestions if you care to take a look. Thank you! source: https://bit.ly/3giqrBU Why: Composing music is different for everyone, yet some practices are employed by many musicians. One such practice is to record a musical idea on a phone, capturing the idea at its freshest, and for many, clearest. This often leads to a lengthy catalogue of chronologically organized recordings that can be difficult to parse when sitting down to flesh out a piece of music – what matters most is the content of the idea, more so than when it was conceived. The purpose of SoundSeeker is to allow you to organize musical ideas based on their content instead of when they came to be, and to serve as ...

Show HN: Tiny:optional – a C++ optional that does not waste memory tiny::optional is a header-only C++ library for x86/x64 intended to be a drop-in replacement for std::optional with the twist that it does not require additional memory for bools, floats, doubles and raw pointers. For example, a standard optional double has twice the size of a raw double because of 7 padding bytes after the internal bool. These wasted bytes can have a notable impact on performance in memory bound applications. On the other hand, a tiny::optional double has the size of a double by exploiting unused bit patterns. For other types such as integers, it allows to specify a "sentinel" value that represents the empty state, again causing the optional to have the same size as the underlying type.

I've updated it so I can read Hacker News just the way I want to. ## Major changes/innovations: - Default news feed is from hckrnews.com (all items that have made the HN homepage, sorted by date). - Direct "More..." links (no scrolling required) to dates as far back as June 9, 2010 (No hckernews data beyond this date: https://ift.tt/fVXEoOA ) - https://ift.tt/VzsmJeM combines HN's show and shownew pages. (Removes "did I already read up to here?" confusion when "Show HN" items are in both lists.) - https://ift.tt/4vKZBUN shows the first two pages of Ask HN - Displays last time you visited. - Renders individual comment items. This is useful for sharing, or reading a child comment tree. - "Pagedown...

Show HN: First Working Interpreter Hello everyone! I'm an undergrad in computer science in my last semester. I've tried my hand at a few interpreters the past year. This is my first one that I've actually got set up, with a working lexer and execution tactics. I've implemented the input and output prefixing primitives of the pi calculus. I intended to implement the replication and restriction primitives soon. I find process algebras very interesting. They seem to be an important area of research, to bring the computing ecosystem to a concurrent-first paradigm. This github project isn't much to look at currently; it's my first project of any substance. However, you might find the linked research papers interesting! Feel free to share criticisms, insights, or your favorite process algebra! https://ift.tt/TSUdcP8 October 16, 2022 at 09:59AM

Show HN: ESInfer – Make JavaScript Type-Safe Hello, folks. I'm Jiang, the author of ESInfer. I love writing Javascript because it has a prosperous ecosystem and is quick to get my hands dirty. However, sometimes it's painful when the flow is not fast to follow due to the lack of a type system. To solve this, I wrote ESInfer, a statical inference tool, to automatically type check and generate type annotations for Javascript. It works with pure Javascript without any add-ons to the language or user-space code and supports highly dynamic features, such as the modification of prototypes. It is still in the very early stage, which offers almost all ES5 features and a select set of ES6 features like array/object destructing. I'm working hard to bring all ES6+ features into it incrementally. If you heavily use javascript/typescript and do NOT want to write the type annotation sh*ts anymore, give it a try :) https://esinfer.com/ October 15, 2022 at 05:03PM

Show HN: Circumflex, browse HN in your terminal Some two years ago, I found myself spending a lot of time in the terminal between learning vim and discovering new command line tools. I was surprised to see that the niche of HN clis was (relatively) small, and so I decided to write my own command line tool for browsing HN called `circumflex`(`clx`). `clx` is written in Go using Bubble Tea[1]. You can read the comment section or the linked article in reader mode in the pager `less`. Using `lesskey` to add custom keybindings, the replies can be collapsed and expanded in real-time (but not individual replies, only all replies at once). Behind the scenes I am appending invisible unicode characters to each line so that I can use the custom keybindings to filter them out. The same technique is used to allow for jumping between top-level comments. I spent a lot of time thinking about syntax highlighting and finding relevant bits to highlight while also not going overboard with colors. The end ...

Show HN: Code of War – Satirical book about moving up the IT corporate ladder Hello dear HN crowd, I love when I stumble upon a developer war story in a random comment here on HN. I love it so much that I also wanted to share some of the stories I've collected over the years working in IT. I came up with the idea to present the stories in a somewhat unusual way, in the style of the malicious self-help book. The book gives you advice on how to succeed in IT, from the interview phase to the management, by acting like an immoral, unscrupulous person. The advice is based on experiences with some shady, weird people I met throughout my career. After every chapter, there's a short story about the person who was the chapter's inspiration. I've worked with those people, so everything is a first-hand experience! This was my first attempt at doing something like this, so go easy on me! :) One cool fact! I used entirely free and open-source software for the creation of this title....

Show HN: Cobalt – social media downloader with no bullshit Hey, HN! I made my own social media downloader because I got annoyed by others that either shove 50 ad banners down your throat, or require you to do some extra steps. The frontend page is light and all processing is done on the server, so it runs speedily on pretty much anything. It also has a bunch of download/ui customization options, but none of them are forced on you. My main goal was to make something that's open, easy to use, and not annoying to deal with. Please take a look at it and let me know what you think, I'm thirsty for feedback and opinions. You can also take a look at its source code and judge my coding abilities: https://ift.tt/rSncfGK https://co.wukko.me/ October 12, 2022 at 09:33AM

I built it because I wanted helpful tutorials without having to watch an entire video. In a later version, I was thinking it could be cool to show other screenshots from the video throughout the transcript, but there’s really no easy way to do that outside of downloading the video and taking clips from there.

Show HN: My book for programmers called “Junior to Senior” was published today After a four year journey, the book I wrote to help junior and mid-level programmers earn their first promotion was published today . The book is titled Junior to Senior: Career Advice for the Ambitious Programmer and is now available on Holloway’s website[0]. I truly believe that soft-skills are what makes the difference between a good programmer and a great one. I also believe that anyone can learn the soft-skills needed to accelerate their programming career. I wish I’d had better resources to learn these things in the early years of my career and I’m hoping this book will become a useful resource for the next generation of programmers to build successful careers. What this book covers: Choosing a career path: generalist vs. specialist What makes you a senior engineer? How to deal with feeling like an impostor How to build trust and work with your manager How to recover when you make a mistake, and what t...
