huangyz0918··on Ask HN: Could you help me to build a database?
We can only know your device information and the picture, whatever you took. The contents of picture are unnecessary.

Thank you for your understanding and help. Thanks!

huangyz0918··on What is the working principle of the invisible watermark?
At present, this framework is still under development, and the invisible watermark only implements the LSB spatial domain. LSB is very poorly robust and does not support lossy compression, so I am going to make a watermark added to the frequency domain in the next step. For an Android framework, I think it is enough to provide these two interfaces.

You can see the Demo about the invisible watermark in README: https://github.com/huangyz0918/AndroidWM/blob/master/README....
huangyz0918··on [Android Library] Add invisible watermarks into your photos!
This library supports those kind of watermarks:

- image watermark

- text watermark

- LSB invisible image watermark

- LSB invisible text watermark

- Frequency domain invisible image watermark (developing)

- Frequency domain invisible text watermark (developing)

and also supports invisible watermark detections.

Contributions welcome :)

We want to collect data in challenging environments around the world, maybe some places without network connections. You can download ODK Collect and have a try.

I'm one of a developer for Open Data Kit. And This is the first open source community that I have contributed to, I have to say, ODK is an awesome place to get start with open source developments and all the ODKers are so warm hearted and cool! ODK can teach many things you don't know and all you need to do is to claim an issue and send a PR!
huangyz0918··on Open source tutorial for Hackintosh installation
Thank you,it sounds good !

yeah maybe we can focus on the clover config in this repo :)

Hackintosh is good but I think most people just want a macOS system, they don't really care about how much they can learn from hackintosh installations.(e.g., bootloader, dsdt, kexts adaptions). This repo may be more suitable for those geeks and those who want to understand the computer OS better. So it will focus more on the technologies and theories (if one just want to install macOS and get no interests in hackintosh, he should turn to tonymacx86 or some other forums)

Yes many Hackintosh users are iOS developer, I built my first Hackintosh in order to develop my iPhone apps too.

There are a lot of people have posted their configurations and successful installation guides in GitHub, but they are hidden very deeply so that many newbies cannot find the configuration the same with their machine. It’s a great pity:( So I came up an idea that why not to build an index which can collect some basic knowledge about operation system and successful Hackintosh configurations together? Maybe we can add some systematic guides in it too. It’s just a new repo, but I will do this step by step.
