There are a few remaining things I want to learn while I'm still an undergraduate:
Compilers, Electronic Circuit and VLSI

The latter two are tough and confusing...

Got a new job

OK, here's a take for you:

PDFs are not a document format. Instead, as they encapsulate an executable (postscript) and a set of resources that are accessed in a sandboxed environment, they constitute a container.

Announcing #bpftop: Streamlining #eBPF performance optimization

https://netflixtechblog.com/announcing-bpftop-streamlining-ebpf-performance-optimization-6a727c1ae2e5

"'"bpftop provides a dynamic real-time view of running eBPF programs. It displays the average execution runtime, events per second, and estimated total CPU % for each program. This tool minimizes overhead by enabling performance statistics only while it is active."'"

Good bye Purdue University!

It has been so intense, now suffering from jet lag and getting back to real life.

Was working out today wearing this tshirt, suddenly someone asked me "You use Linux? I use Arch by the way..."

At this point obviously I'm here to drink more

First week at purdue

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```

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":

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:

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…

#Linux #Kernel patch review process finally moving on from mailing lists

Hey #Linux #Kernel people. Last year we had the first #Kernel Devroom at #FOSDEM. And we're running the #Kernel Devroom for #FOSDEM in 2024 as well!

#FOSDEM 2024 is taking place over the weekend of the 3 & 4 February in Brussels, Belgium!

It is a wonderful event that's very close to my and a lot of people's hearts!

Join @rppt, Daniel Borkmann, and @stgraber, and myself and make this another great #FOSDEM!

We're very excited for your submissions!
