Babble – Communicate privately on state-sponsored social media

In plain words
Babble is a messaging app designed for people in countries with severe internet censorship and surveillance, such as China, where conventional encrypted messaging services are blocked by firewalls. It enables private communication on state-sponsored social media platforms where direct access to tools like Signal is unavailable. The app targets ordinary users who need to bypass restrictions to communicate freely without government interference or message deletion.

In the maker’s words, at launch
Thanks for checking out Babble! You might wonder why this app is even useful and why not just use Signal/PGP. This app's target audience is actually ordinary people in China or similar countries who are under severe government surveillance and censorship, where access to Signal and similar E2EE messaging software is blocked by nationwide firewalls, such as the Great Firewall of China (GFW). Chinese people have been deprived of freedom of speech even before the COVID-19 pandemic. Li Wenliang, who was among the first to notice the spread of the virus and warned his colleagues about it in a private WeChat group, was admonished by the police for "spreading rumors"; his punishment was then aired on the national TV channel. After Wenliang passed away due to getting COVID-19 himself, discussions about it on China's public Internet were highly restricted; most discussions will be deleted upon being posted, which was done by some automatic keyword detection mechanism. Things got even worse over the years and especially during the Shanghai lockdown in early 2022. Everything related to questioning the public health policy is banned. Many people posted articles about how bad Shanghai's economic and social situation is on their WeChat public accounts. None of these articles, not even their accounts, can survive for longer than a few hours. Even articles crying for help, because people were starving, got deleted. A video called Voice from Shanghai Lockdown (https://youtu.be/38_thLXNHY8), which contains audio recordings of desperate Shanghai people during the lockdown, went viral on Chinese social media at the end of this April. Unsurprisingly, this video was immediately censored. People got angry and tried to spread this video as much as possible by re-posting it again and again, racing against the detection algorithm. But it was futile. It's just like 1984, where the number of words available to say "legally" is decreasing. There are no tools available for people to speak out. Public social media and private messaging apps are all monitored by the government. Foreign tools such as Telegram, Signal, or anything similar are blocked by the GFW. PGP is too technical for normal people. The goal of Babble is to provide those people with a cryptographic and steganographic tool that's easy enough to use but secure enough against a censorship system. It's not perfect as of now, but we are making an effort to make it better. Yes, Babble might get removed from the App Store in China if the Chinese government asks, but it's fundamentally different from Signal being blocked - there are a considerable number of people in China who has an overseas Apple ID so that they can download apps not on Chinese App Store, but to use Signal, you have to bypass GFW, which fewer people know how to. One of the real challenges for this project though, is how to get people aware of the situation, because our education is brainwashing and people are starting to take surveillance and censorship for granted. And it's very hard for the app to reach its intended audience because the surveillance system is designed to prevent them from accessing this kind of tool.

Hello, HN - I wanted to share this puzzle game I made during my vacation. I'm rather fond of the pipes puzzle where your goal is to restore a scrambled network of connections by rotating tiles. It's usually played on a grid of squares and this all started when I decided to make a programmatic solver for that kind of puzzle. Then I realized that with some minor changes the solver could generate new puzzle instances. I thought about what kind of puzzle to make and someone suggested a hexagonal grid. Adapting the generator wasn't too hard but then I had to create a way to play this variant. So…

We're building Parsnip to create a "tech tree" of cooking skills that allows anyone to level up on the building blocks of cooking knowledge while tracking their progress over time. It took us a few iterations to figure out the right product; here's the story of our latest pivot: [https://parsnip.substack.com/p/a-new-hope] The goal is to create a personalized way to learn any recipe on the Internet, then use this as a springboard to help home cooks of all levels solve the problem of repeated meal planning in a 10x better way:…
