Show HN: Modifying Clang for a Safer, More Explicit C++ https://bit.ly/3A6k1w4

Show HN: Modifying Clang for a Safer, More Explicit C++ Modified C++ Inspired by the paper "Some Were Meant for C" by Stephen Kell, I decided to show that it's possible to iterate C++ to be safer, more explicit, and less error-prone. Here's a possible starting point: I didn't invent a new language or compiler, but took the world's best compiler, clang, and modified it to begin iterating towards a new furture of C++. Naming things is hard, so I call this 'Modified C++'. Some of the following could be implemented as tooling in a linter or checker, but the idea is to update the compiler directly. I also wanted to learn more about clang. This compiler needs a flag to enable/disable this functionality so that existing library code can be used with a 'diagnostic ignored' pragma. You can build clang using the normal non-bootstrap process and you'll be left with a clang that compiles C++ but with the following modifications: - All basic types (excluding pointers and references) are const by default and may be marked 'mutable' to allow them to be changed after declaration - Lambda capture lists must be explicit (no [&] or [=], by themselves) - Braces are required for conditional statements, case and default statements within switches, and loops - Implicit conversions to bool are prohibited (e.g., pointers must be compared against nullptr/NULL) - No goto support - Explicit 'rule of six' for classes must be programmer-implemented (default, copy, and move c'tors, copy and move assignment, d'tor) - No C style casts Here's an example program that's valid in Modified C++: mutable int main(int, char**) { mutable int x = 0; return x; } Here's another that will fail to compile: mutable int main(int, char**) { int x = 1; x = 0; // x is constant return x; } I'd like your feedback. Future changes I'm thinking about are: - feature flag for modified c++ to enable/disable with 'diagnostic ignored' pragma, to support existing headers and libraries - support enum classes only - constructor declarations are explicit by default - namespaces within classes - normalize lambda and free function syntax - your ideas here https://bit.ly/3py4Wyc August 17, 2022 at 08:21PM

Show HN: An HTML endless runner under 900 lines without frameworks or libraries https://bit.ly/3Ch0WcX

Show HN: An HTML endless runner under 900 lines without frameworks or libraries My wife and I recently submitted to a mobile game jam on Newgrounds (yes, it's still around). What started as a question of whether we could do it somehow morphed into whether we could do without so many of the seemingly needless complications rampant in our respective industries. My wife thus did all the art as traditional frame-by-frame animation (no puppets or tweening) and I preceded without a game engine. I did use a pre-processor that gives JS a Lisp syntax (Parenscript), because C-syntax is gross. We hope the end result, while definitely of small scope, will serve to inspire some thought as to what is and isn't needed in your next project. https://bit.ly/3QCNN2i August 19, 2022 at 05:12AM

Show HN: I spent a year designing a low profile, minimal mechanical keyboard Hi HN, During lockdown I took up the keyboard hobby but I couldn't find anything I liked the aesthetic of. So I set out to design my own keyboard from scratch that shunned the gamer look in favour of a more minimal, serious design. I've built several prototypes but I would love to get some feedback from the HN community. https://bit.ly/3A5e3vp August 18, 2022 at 10:24AM

Show HN: StoneDB—A Real-Time HTAP Database Based on the MySQL Kernel https://bit.ly/3PxlHEt

Show HN: StoneDB—A Real-Time HTAP Database Based on the MySQL Kernel StoneDB is an open-source hybrid transaction/analytical processing (HTAP) database designed and developed by StoneAtom based on the MySQL kernel. It is the first database of this type launched in China. StoneDB can be seamlessly switched from MySQL. It provides features such as optimal performance and real-time analytics, offering you a one-stop solution to process online transaction processing (OLTP), online analytical processing (OLAP), and HTAP workloads. StoneDB is fully compatible with the MySQL 5.6 and 5.7 protocols, the MySQL ecosystem, and common MySQL features and syntaxes. Tools and clients in the MySQL ecosystem, such as Navicat, Workbench, mysqldump, and mydumper, can be directly used on StoneDB. In addition, all workloads on StoneDB can be run on MySQL. StoneDB is optimized for OLAP applications. StoneDB that runs on a common server can process complex queries on tens of billions of data records, while ensuring high performance. Compared to databases that use MySQL Community Edition, StoneDB is at least 10 times faster in processing queries. StoneDB uses the Knowledge Grid technology and a column-based storage engine. The column-based storage engine is designed for OLAP applications and uses techniques such as column-based storage, Knowledge Grid-based filtering, and high-efficiency data compression. With such storage engine, StoneDB ensures the high performance of application systems and reduces the total cost of ownership (TCO). https://bit.ly/3IhU7J8 August 18, 2022 at 06:56AM

Show HN: Allsearch – Making it easier to use different search engines seamlessly https://bit.ly/3Qw5ell

Show HN: Allsearch – Making it easier to use different search engines seamlessly Allsearch is a tool I made after getting fed up with Google's search results and reading up on conversations on HN about the state of search on the internet. This is a tool I made as a spiritual successor to GnodSearch ( https://bit.ly/3dCKd9Q ), which I've seen in a couple conversations about search on HN. GnodSearch is great, but a bit barebones in terms of looks and functionality; Allsearch is my attempt to build off of it. Similar to Gnod, Allsearch allows you to apply any given search query to a search engine of your choice (either through only keystrokes, or via mouse). However, it also allows you to add your own engines to its catalogue, and allows you to define macros to use multiple engines simultaneously (useful for easily comparing engines). It's not feature complete; there are still some things I'd like to add in. There are way more engines I want to add to it's default catalogue, and I also want to add in the ability to export your settings to allow people to easily share their Allsesarch configurations. Curious about people's thoughts on it :) https://bit.ly/3Qw9UHz August 17, 2022 at 07:47AM

Show HN: A network for Americans who can't afford health insurance https://bit.ly/3QxgHkn

Show HN: A network for Americans who can't afford health insurance Hey HN, launched this recently and looking for early feedback. The problem to solve: In the US, patients who can't afford health insurance are regularly charged the highest prices for healthcare - prices that are deliberately inflated by 2x-4x above market. But theoretically they should be getting the best prices, because they are paying without the expenses and delays of insurance claims. However, insurance contracts are written in a way that prevents anyone outside a network from getting better prices than insurers. The Pocketero solution: An affordable non-insurance network for people who pay out of pocket for healthcare, especially those who can't afford health insurance. Network members get the best prices from network providers. If you have any comments about the design, implementation, business model, etc. - please share your thoughts! https://bit.ly/3STkme3 August 16, 2022 at 09:41PM
