Manual intervention for pacman 7.0.0 and local repositories required
With the release of version 7.0.0 pacman has added support for downloading packages as a separate user with dropped privileges.
For users with local repos however this might imply that the download user does not have access to the files in question, which can be fixed by assigning the files and folder to the
alpm group and ensuring the executable bit (+x) is set on the folders in question.$ chown :alpm -R /path/to/local/repo
Remember to merge the .pacnew files to apply the new default.
Pacman also introduced a change to improve checksum stability for git repos that utilize
.gitattributes files. This might require a one-time checksum change for PKGBUILDs that use git sources.source

Zen 2 doesn't use previous target history to predict indirect branches, so it often mispredicts if target selection doesn't correlate with plain taken/not taken global history.

The PhD Paradox: A Journey into Academia’s Upside-Down World
Imagine a world where becoming a doctor isn’t about years of rigorous study, but about showcasing your life’s work. That’s how doctorates used to roll. You’d write a book, make a groundbreaking discovery, and voila, a doctorate was yours. Fast forward to today, and we’ve flipped the script. Now, a PhD is less about what you’ve done and more about preparing you for a career in academia, often at a subsidized cost. Sounds great, right?
Here’s the catch: this system works like a charm as long as universities are expanding. But what happens when they hit the brakes? You guessed it – a PhD glut. With more PhDs than professorships, the job market turns into a gladiatorial arena where only the most politically savvy survive. This isn’t just about competition; it’s about who can navigate the labyrinthine politics of academia.
Universities, with their pristine campuses and lofty ideals, market themselves as bastions of brilliance and nurturing. But peel back the curtain, and you might find a different story. Professors, often out of touch with the real world, teach subjects they’ve never truly experienced. Take entrepreneurship, for example. You’d think those teaching it would have started a business, right? Nope. Many haven’t even stepped into a startup, let alone run one.
Then there’s the publishing game. Tenured professors, the supposed engines of new knowledge, might not even produce a paper a year when you account for co-authorships. And when they do publish, well, let’s just say the quality can be…variable. Even at the pinnacle of academia, like Harvard, the standards can slip, as seen with its former president’s less-than-stellar publication record.
So why do we keep pushing our youth into this system? It’s all about signaling. A degree, especially a PhD, is like a badge, a shiny sticker that says, “I’m educated.” But here’s the kicker – this badge might not make you more productive or happier. In fact, less time in school and more time in the real world could be the real recipe for success.
Imagine if we recruited professors not just for their academic credentials but for their real-world achievements. People who’ve actually built things that work, could revolutionize how we teach software engineering or entrepreneurship. But we’re not there yet. We’re still caught in a system that values form over function, prestige over practicality.
Our love affair with academia might be making us less productive and more miserable. Maybe it’s time we rethought this whole PhD business, not as a rite of passage into an elite club, but as a tool for real-world impact. After all, isn’t education supposed to prepare us for life, not just for more education?
