Opinions on usage of Linux at college?

I used to use Linux a couple of years ago on my Dell G15 and it was absolutely wonderful (Arch with KDE), so you may be wondering "If you were happy about it, why are you even asking this question".

Well, first of all I was not at college back then, and now I use a different laptop (Lenovo Yoga Slim 7 14IMH9). I'm not concerned about connectivity between devices or what programs I can run on Linux, but I'm concerned about the PowerPoint and Word documents that I send to my professors every week. I'm studying to become a teacher, thus you may understand why these documents are so important for me. Sometimes, I'm literally graded based on these documents.

I'm afraid that a Word or a PowerPoint document that I send to one of my professors may not be compatible with Windows. For example, an essay that I've written on my Linux laptop may not work on my professor's Windows laptop for some random compatibility issue. I don't think that there will be any problems on my side, but rather on my professors' side because I don't think that none of my professors, except maybe one of them, have any idea about Linux let alone having used any distro at any point in their lives.

Also, sometimes I have to do presentations and/or give lectures, so I'm scared that the projector that I have to use may not work with my PC for some random reason.

So, I would really appreciate it if you guys could help me with this situation.

What are the main issues you have with Linux?

Literally the title: what are the main issues or the main parts you wish would be easier or done differently when using a Linux distro? From the moment you installed it, to the moment you're using it for a long time, to features you wish it would have or do better than it does already. What apps or looks or capabilities you wish it would be able to have or do from the get go?

This is a question for people at their start of the journey with Linux, to experienced, people who edit or build their own distro and people who mainly use one flavor in it's original ISO.

need papa linus to save us.

I always take the surface level complaints about anything linux related with a grain of salt, when i looked at btrfs i saw them. But i wanted that snapshot granularity + compression. So i went for it.

There are a lot of uAPI things that are "odd" especially with the whole snapper "make the snapshot subvolume then unmount then make it then remount then delete and don't do it wrong or snapper has a stroke" sorcery. I immediately moved to just doing snapshots manually because no way i was going to even touch something that depends on a naming convention to work.

I really liked btrfs, i was able to get my sophisticated layout, i do a lot of NPU related low level projects so i have a flat layout with seperate subvolumes for ssh, certain compilers like v++ i will build from source and keep isolated so i can have them out of the equation for a different one path resolution wise.

The issue arrived however, when i realized it was just the fact i THOUGHT i liked it because of running btrfs send to my network drive with it as RO, running btrfs receive, then checking that it hit the drive. I mean if you look at a directory and see the file than it's there... one would assume.

Suffice to say, one day i checked on the drive to grab a python wheel i knew i had tucked away and had accidentally delete on my test machine. The snapshots just kind of walked away... Like i thought peter dinklage was going to come to me and say the "the file system just... never cared" or some shit. Wasn't an unmounted subvolume, wasn't a userfacing miss. The data was just gone.

This brings me to the main point of this post, PLEASE LET OVERSTREET BACK INTO THE MAINLINE EMPEROR LINUS. It truly has boiled down to my issues with it, and just the objective state of the actual btrfs team that all roads lead back to the overstreet. Read the front page to his website and you see exactly the type of shit that is overlooked in btrfs development but is just wrong. "Never writes bad data", things that are just outlook and introspective. But the type where there's objectively correct and then there's stupid

Overstreet pushed a filesystem commit for an issue that was seriously important for bcachefs users- because i mean having the kernel doesn't really matter when you have critical filesystem issues that need to be constrained for some autisitc nerds unrelated NPU drivers ( that's me btw, not to demean ). Bcachefs is structurally better than btrfs even as a dkms, but pretty unusable for mainline users.

Regardless of it's usage btrfs is still just beating at a dead horse, i do not see why the technically inferior filesystem is being taken seriously when the only reason it's still the COW standard is some maintainers having their feelings hurt. Like idk how anybody could look at that commit past the merge window and not think "oh that'd be a pretty fair exception"

What is the general consensus on this one? my bad for the long post, just wanted to make it clear i didn't just hastily snapshot things and send as RW with no btrfs receive being ran- or just anything that isnt in the docs.

I say petition to bring/invite Kent Overstreet to come back into the kernel cycle. He's got an ego, he's kind of a douche, but in my opinion even if charles manson was on the prison's kindle E book, rooted it, and was pushing something that showed promise -- id go with it.

just overall curious on what the community thinks about this topic, raid 5 coming before the heat death of the universe!

are there any "4th level" distros?

There's probably a better term for this already. by "level" i mean how many layers of dependancy is there for the operating system. For example, Mint is a 3rd level because it's built on Ubuntu which is built on Debian.

are there any distros built on top of the big user friendly ones like mint or zorin OS ?

I have no idea why they would exist

Looking for old Realtek wifi cards and USB adapters

Hi!

I'm looking for old Realtek wifi cards and USB adapters for my hobby, which is fixing/improving their Linux drivers:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/log/?h=v7.1-rc2&qt=author&q=rtl8821cerfe2

If you're in the EU (+ Norway, Iceland, and Liechtenstein?) and you have a device you want to donate, please message me here or email me. (You can find my email address in any of the commits listed at the link above.)

Some of these devices can still be bought today, so money can help too.


RTL8188SU / RTL8191SU / RTL8192SU

These USB adapters used to be supported by the r8712u module, but it was removed in kernel 6.13 because it used outdated APIs and no one did anything about that for years. r8712u probably can't support WPA3, so the goal is to add support for this chip to rtlwifi, which already supports the PCIe version.

RTL8191SE / RTL8192SE
RTL8723AE
RTL8192CE
RTL8192DE
RTL8723BE
RTL8192EE / RTL8192EEBT

RTL8723AU

This was a ~special~ module used in some Lenovo Yoga laptops. I'm hoping it can be hooked up to a USB cable, since it uses USB to communicate with the system.

RTL8188CUS

Lots of USB adapters used this chip but they're out of stock now.

RTL8192DU with two USB interfaces ("bNumInterfaces 2" in lsusb)

This is an unusual USB adapter that can work in both the 2.4 GHz band and the 5 GHz band at the same time. Products that likely have this variant of the chip: SAPIDO AU-5125, SAPIDO AU-5015, Planex GW-USFang300, Planex GW-USDual300, Planex GW-USUltra300.

Newer devices are also welcome:

RTL8821CU (wifi + bluetooth) / RTL8822BU (wifi + bluetooth) / RTL8812CU (wifi only)

These would be just to have a complete collection, as I already have other versions of these chips.

RTL8723DE
RTL8821CE
RTL8822BE
RTL8814AE

As far as I can tell this is only found in desktop cards, which I can't use unless it's actually a mini PCIe card in an adapter.

RTL8852AE
RTL8852BE
RTL8852CE
RTL8922AE
RTL8922DE

BeeMesh++ — A distributed volunteer computing framework built with modern C++ & Asio

Hi,

We have been working on an open-source project called BeeMesh++ which is the C++ implementation of the original python code BeeMesh.

This is basically like **SLURM** but for multiple geographically independent devices.

It uses a nature-inspired architectural model:

The Hive (Orchestrator): Manages the state of the network, tracks available compute nodes (bees), handles job dispatching logic, and aggregates results.
The Bees (Workers): Volunteer compute nodes that connect to the Hive, announce their availability, listen for incoming serialized task payloads, execute them, and stream the results back.

NOTE: This is still in it's early stages.

Plan ahead would be to implement encryption for all the network communications, communication between bees, parallelizing independent code blocks etc.

Feedback, architectural critiques, or code reviews appreciated.

Google GTIG just documented the first confirmed AI-developed zero-day vulnerability — some technical details worth discussing

So GTIG dropped their Q2 AI Threat Tracker on May 11 and I think the most technically interesting finding has been underreported relative to its significance.

A cybercrime group was planning a mass exploitation campaign. The Python exploit scripts associated with the campaign had hallmarks that GTIG says indicate "high confidence" the code was written with AI assistance: educational docstrings throughout, a hallucinated CVSS score, structured "textbook Pythonic" formatting, detailed help menus and a clean ANSI color class. No human writing an exploit for actual deployment bothers with any of that.

The actual vulnerability — which GTIG helped disclose and remediate before it was deployed — was a 2FA bypass in a popular open-source web-based system administration tool (unnamed for now). Not a memory corruption bug. A semantic logic flaw: the developer hardcoded a trust assumption that contradicted the 2FA enforcement logic elsewhere in the codebase. Traditional fuzzers don't catch that. LLMs, apparently, do.

GTIG's explanation of why is worth reading: frontier LLMs can "read developer intent" and correlate enforced security policies against hardcoded exceptions. That's a completely different threat model than what most SAST tools are built around.

Beyond the zero-day, the same report covers PROMPTSPY (Android malware using Gemini as an autonomous UI navigation engine), CANFAIL and LONGSTREAM (AI-generated decoy code to confuse analysts), and the TeamPCP supply chain hits on LiteLLM and BerriAI via PyPI.

Some questions for the community:

1. Is your organization treating semantic logic flaws (hardcoded trust assumptions, contradictory auth enforcement) differently from memory corruption bugs in code review? Because if AI can find them at scale, so can attackers.
2. For those running AI API gateways — have you rotated credentials after the LiteLLM/BerriAI PyPI compromise? What's your secret management posture for AI API keys?
3. GTIG says the most common threat actor use of LLMs is still just basic research and troubleshooting — but zero-day development is now proven possible. How do you model this in your threat matrix?

Full technical write-up here if you want the PROMPTSPY attack chain and the MITRE ATLAS mappings: https://www.techgines.com/post/gtig-ai-developed-zero-day-vulnerability-promptspy-2026

I previously covered the first AI-assisted OT attack (Dragos / Monterrey water utility) here if you want more background on the AI-as-attacker threat progression: https://www.techgines.com/post/ai-assisted-ot-attack-claude-scada-water-utility-dragos

Techgines GTIG Confirms the First AI-Developed Zero-Day Vulnerability in the Wild — And the Attack Landscape Just Permanently Shifted I'll be honest — when I first read Google's GTIG AI Threat Tracker report dropped on May 11, I had to go back and re-read the section twice. Not because it was poorly written. Because I wanted to make sure I wasn't misreading what it was actually saying.…
