Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

QEMU Version 9.0.0 Released
My most-wanted QEMU feature: https://github.com/qemu/qemu/commit/a2260983c6553
Using `gic-version=3` on macOS you can now use more than 8 cores on ARM chips.

Autoconf makes me think we stopped evolving too soon
A better solution is just to write a plain ass shell script that tests if various C snippets compile.
https://github.com/oilshell/oil/blob/master/configure
https://github.com/oilshell/oil/blob/master/build/detect-pwe...
Not an unholy mix of m4, shell, and C, all in the same file.

These are the same style as a the configure scripts that Fabrice Bellard wrote for tcc and QEMU.
They are plain ass shell scripts, because he actually understands the code he writes.
https://github.com/qemu/qemu/blob/master/configure
https://github.com/TinyCC/tinycc/blob/mob/configure
OCaml’s configure script is also “normal”.
You don’t have to copy and paste thousands of lines of GNU stuff that you don’t understand.

Revng translates (i386, x86-64, MIPS, ARM, AArch64, s390x) binaries to LLVM IR
> architectural registers are always updated
In tiny code, the guest registers (global TCG variables) are stored in the host's registers until you either call an helper which can access the CPU state or you return (`git grep la_global_sync`). This is the reason why QEMU is not so terribly slow.
But after a check, this also happens when you access the guest memory address space! https://github.com/qemu/qemu/blob/master/include/tcg/tcg-opc... (TCG_OPF_SIDE_EFFECTS is what matters)
But still, in the end, it's the same problem. What QEMU does, can be done in LLVM too. You could probably be more efficient in LLVM by using the exception handling mechanism (invoke and friends) to only serialize back to memory when there's an actual exception, at the cost of higher register pressure. More or less what we do here: https://rev.ng/downloads/bar-2019-paper.pdf

Multipass: Ubuntu Virtual Machines Made Easy
Some of these tools include Oracle VM VirtualBox (that I've used since before the acquisition of Sun Microsystems by Oracle), VMWare Workstation Player, and QEMU, but last year, I found out about Multipass.

Libsodium: A modern, portable, easy to use crypto library
For C/C++ projects that use meson as the build system, there is an excellent way to manage dependencies:
https://mesonbuild.com/Wrapdb-projects.html
https://mesonbuild.com/Wrap-dependency-system-manual.html
meson will download and build the libraries automatically and give you a variable which you pass as a regular dependency into the built target:
https://github.com/qemu/qemu/tree/005ad32358f12fe9313a4a0191...
https://github.com/harfbuzz/harfbuzz/tree/main/subprojects
https://github.com/harfbuzz/harfbuzz/blob/37457412b3212463c5...
Or, if you're using proper operating systems, they're managed by the usual package manager, just like everything else.

Top 6 Virtual Machine Software in 2023
For all the users of the Linux platform, QEMU is the VM that you should go for. This software comes without any price tag and works as an emulator of various machines with utmost ease and completion; the software uses dynamic translations to emulate hardware peripherals and enhances its overall performance. If you are using QEMU as a virtualizer, then it will function exactly like the host system (provided you have the right set of hardware).

UTM for Developers
In this tutorial, we set up macOS and Windows virtual machines on UTM, a macOS application that provides a GUI wrapper for QEMU, a powerful open-source emulator and virtualizer. UTM allows you to easily manage and run virtual machines without memorizing complex commands. It also has special handling for macOS, making it simpler to install compared to other virtual machine software.

Google Scholar PDF Reader
Maybe try Zotero[1]. There are many addons which can do what you need.

I wrote my bibliography manually (Dont ask why). How do I sort it by the first letter of each entry?
And next time, you use a real literature management program like zotero (some university libraries offer classes, there is a r/zotero, etc) or jabref to create a proper bibtex file with the references. It is not that difficult, and keeps you sane (esp. if a paper has to be formatted for a different publisher). See e.g. learnlatex.

Ask HN: Who is hiring? (December 2023)
Zotero | Remote | Full-Time or Part-Time | https://www.zotero.org
Zotero is an open-source project that develops software to help people collect, organize, annotate, cite, and share their research. Our software is recommended by most universities and used by millions of students, scholars, scientists, and researchers worldwide.
We're looking for a JavaScript developer to work on Zotero "translators" — the pieces of code that let people click a button in their browser toolbar on any webpage and save high-quality metadata and files to their Zotero libraries. If you like web scraping, APIs, data formats, and exploring sites in the browser devtools, this would be up your alley. As a core Zotero developer, you'll also have the ability to work across Zotero's vast ecosystem and help shape the future of the project.
This is an open-ended contract role that can scale up and down in hours based on availability and workload.

Is there an equivalent of calibredb for research papers?
I use the free and open source Zotero which I think you'd find very calibre-like and manage notes and concept linking with org-roam in emacs.

Will I lose everything on Zotero?
If you can't hold the urge to know, you can check on the Zotero web library if all of your things are still there

Advice for Thesis students
Resources: ZOTERO. Zotero is a free (you can pay to get more storage), open-source citation manager with optional browser plugins. IT WILL FORMAT CITATIONS FOR YOU. (sometimes you have to edit them, but most of the time it can pull metadata and format things correctly on its own). You can sort your references into folders or with tags, read and annotate PDF copies on your computer or in a mobile app, and make notes - which I used to keep track of specific quotations I wanted to use.

Extra Reading for Archaeology / Ancient History
You can also use online resources like The Encyclopedia of Archaeological Sciences, that I think is mostly free or the Handbook of Archaeological Sciences which I think is also mostly free. If you can't get a hold of those things you can also email the authors/editors and they might send you a free copy or look them up on Academia.edu and see if they have a free version. Also, if you don't already, use Google Scholar, it's the best resource for finding free articles and topics to read. It's also never too early to start using something like Zotaro, Mendeley, or Endnote to keep track of your readings and help you with citations/references in papers. You can literally download the citation, import it into one of those systems and it automatically formats your referencing.
