My friend told me to play Minecraft together (It's been 4 years since last played) but I can't because Microsoft threw away my Mojang account 😠 😠

```As of December 18, 2023, the post-migration process for Mojang accounts has officially ended```

By the way, it's not easy to take general kernel or MM topic as a project during an internship or as a team project in university. I guess it will remain a hobby for few years...

My next plan for this winter vacation is to do a research project in compilers with a group of students (at Purdue University, USA)

After that, I don't know. Maybe another internship or just prepare for graduation and do some patches.

Yesterday, my internship finally finished. It was fun and inspiring to look at a project (QEMU) other than Linux, and learn how PCIe/CXL/ACPI/UEFI works in general.

Now trying to do some work (a little) on CXL emulation in QEMU, though I'm not sure how far I want to pursue as my heart is still in MM.

This link captures the confusion about how to pronounce "fsck":

https://lwn.net/Articles/190223/

Here's the truth. Ted Kowalski, username frodo, may he rest in peace, was the original author, just down the hall from my office in Murray Hill, and his name for the program had a 'u' where there is now an 's'. Management made him change it for distribution, but they couldn't make him change his pronunciation.

Interesting post from the Android Rust compiler team:

https://android-developers.googleblog.com/2023/12/faster-rust-toolchains-for-android.html

Seems to line up with my benchmarks for performing a lot of the same optimization techniques to LLVM and clang and it is cool to see the amount of savings that this translates to for CI. Reminds me that I should look at integrating my kernel.org LLVM builds into tuxmake so that we can use them with tuxsuite…
