+For many years during our radare2 times we participated in Google Summer of Code. Also, in addition
+to hosting those we often did our own Summer of Code. To continue the tradition, albeit under a
+completely new name and a few differences we introduce the RSoC 2021.
+[Together with the KeenLab of Tencent](https://keenlab.tencent.com/zh/2021/03/04/RSoC-keenlab-2021/) we provide an opportunity for students
+to apply for the internship and to work on improving Rizin. The application period
+continued through all of April with the fierce competition between candidates. Finally, we chose
+two.
+Let them introduce themselves, and we wish them luck!
+
+## Intermediate language improvements
+
+Hello, I'm Heersin from China, an undergradute student majoring in information security. At the very first, I was looking for a handful RE tool on the linux platform and then I met radare2. I have been using it to solve some basic CTF tasks and dumps from some malwares. I found there are some imperfect features (the concept of project, ESIL, search... ) and want to contribute to it. After knowing there is a new fork named Rizin, which aimed at refactoring radare2, I started to get involved.
+
+During my spare time, I've done some work for rizin, including:
+   1. Update some out-of-date pages in the rizin documentation and add more examples.
+   2. Fix some bugs in `pyc` plugin
+   3. Add support for `luac` format
+   4. Extend the testsuite to cover more platforms
+
+For RSoC this year, I will be working on the ESIL and follow the [issue 277](https://github.com/rizinorg/rizin/issues/277) to refactor it, and add support for floating point and bitvectors. I will also try to fix some issues in ESIL (e.g. prevent rizin from getting stuck when hitting some C-library functions).
+
+It will be an exciting and challenging summer, looking forward to it!

+## Types analysis
+
+Hi, I'm basstorm from China and I am a 21 years old student. Over the last couple of weeks, I have done some bug fixes and improves around class analysis submodule:
+
+- Fixed display of duplicate vtables in `acll` command when using `aaa` command to analyze over 2 times.
+- Improved the output of the `acll` command to be more concise and clear.
+- Implemented the integration of data from the **RzBin** and **RzAnalysis** modules, which makes the results of class analysis more accurate.
+- Implemented constructor and destructor detection based on the function name.
+
+This summer, I am gonna do the following tasks.
+
+- Improve the support of PDB Structure.
+- Implementing new features in **RzTypes**.
+- Continue to implement new features or bug fixes around class analysis.
