Bidirectional instant file synchronization options

So right now I'm using syncthing to sync a folder (documents) between my desktop and laptop for programming synchronicity and so on between devices but I have a problem; it's kinda slow.

I'd like to be able to, while using Synergy3 between my desktop and laptop, instantly or at least very quickly sync changes to files from my desktop to my laptop while for example running a test build that hot-refreshes on the laptop and having my IDE open on my desktop.

With Syncthing it takes abouuut 15 seconds from save in the IDE to the auto refresh on the laptops running application (natively it takes about 0.5ish) and I was wondering if anyone had any solutions for 2 Linux devices that allows a much more rapid propagation of changes from device to device?

I've found some options looking around on google like Lsyncd but they all have some pretty specific caveats so I'd love to hear what people use in the wild.

Thank you in advance for any advice or ideas!

Systems in question:
Desktop: Manjaro KDE (Kernel 6.12.28-1-Manjaro)
Laptop: Elementary OS 8 (though also running plasma)

Full disk encryption on an existing partition

Hi,

I am wondering if there's a way to enable fill disk encryption without having to reinstall my system.

I've seen cryptsetup reencrypt but the doc is quite on the light side and can't find any real info on this.

Thanks

More groff Quick Reference Guides (-man and -mom)

So I thought I'd create a QRG to groff -man to add to my -me, -mm and -ms ones. It was easy - how small is the set of -man macros! A tribute to the concise way the original developers aced manual writing both for the terminal and on the printed (postnoscript) page. The downside is that -man has not the horsepower to write this document in it's own macro set so I had to use -mm.

Then, having managed quite nicely for much of my own documentation with -me all these years (since the 80's), I recently heard about -mom (I'm 'Tom' at https://linuxgazette.net/107/schaffter.html \- just 21 years late!) so I thought I'd take a look at it.

The best way to learn something like this is to write in it - so now I have a shiny new, if slightly banged up QRG for -mom. Sheesh - -mom is enormous, what an epic piece of work by an obvious genius - but what labyrinthine, baroque and berserk documentation. It's not easy to plumb the depths of it and I must confess I haven't crushed it like the other QRG's. I've run out of patience for now but it's more or less fit for purpose modulo some formatting quirks and the inevitable inaccuracies and errors (all mine). As ever, the real documentation is ground truth, not my QRGs but nonetheless they may be useful to others as well as myself. There is, of course, an online QRG as part of -mom author's documentation but it is itself of book length. MIne is just 8 pages.

All these tributes to the groff way of doing things are on gitlab

Why aren't people talking about AppArmor and SELinux in the age of AI?

Currently, AI bots and software, like Cursor and MCPs like Github, can read all of your home directory (including cookies and access tokens in your browser) to give you code suggestions or act on integrations like email and documents. Not only that, these AI tools rely heavily on dozens of new libraries that haven't been properly vetted and whose contributors are picked on the spot. Cursor does not even hide the fact that its tools may start wondering around.

https://docs.cursor.com/context/ignore-files

These MCP servers are also more prone to remote code execution, since they are impossible to have 100% hard limits.

Why aren't people talking more about how AppArmor or SELinux can isolate these AI applications, like mobile phones do today?

Is linux a red flag for employers?

Hello y’all, I got a question that’s been stuck in my head after an interview I had. I mentioned the fact that I use Linux on my main machine during an interview for a tier 2 help desk position. Their environment was full windows devices and mentioned that I run a windows vm through qemu with a gpu passed through. Through the rest of the interview they kept questioning how comfortable I am with windows.

My background is 5 years of edu based environments and 1 year while working at an msp as tier 1 help desk. All jobs were fully windows based with some Mac’s.

Has anyone else experience anything similar?

Experimenting with Linux cgroups to tweak memory limits for processes

Hey, I recently decided to get back to studying systems regularly and so I am conducting small experiments for learning purposes.I recently explored how cgroups can restrict process memory usage. Here's what I did:

1. Created a cgroup with a 1MB memory limit.
2. Ran a simple program that tried to allocate \~5MB.
3. Observed the process getting killed due to exceeding the memory limit (OOM kill).
4. Checked cgroup memory events to confirm the behavior.

You can find the detailed steps here.

Are there better ways to experiment with cgroups or other interesting use cases you'd recommend I should try? I wish to hear your thoughts and suggestions.

Thanks!

I’m thinking about chatting with my university about installing Linux on some of there older machines.

Okay so I love Linux, and it’s come a longgggg way the last 3 years with valves help. I believe it’s time that workplaces, libraries, etc. to consider using Linux to save money.

My biggest concern right now is the amount of e-waste that is the result of Windows requirements for the security chips. My uni just sent out a notice that they’re getting less money next fiscal year, and I’m thinking about chatting with IT about setting up Linux with KDE on the machines that’d just be sold off for pennies via surplus.

Most people also don’t want to admit it, but folks in admin or similar usually use google suits, and even Microsoft office now is available online now.

Myself, if it wasn’t for Microsoft office being installed I’d be doing all my work through the browser. This leaves me to the argument that Linux is stable enough to be ran as a daily machine.

Even accessibility tools, and other things are available now yes some setup but IT can auto set things up on most new installs.

I’m just trying to figure out is there a really why this hasn’t been a thing, my guess is the lack of management tools and network logins.

I found something in an old server’s RAM. It wasn’t supposed to be there.

I was debugging a memory leak on an old machine.
Dumped a chunk of /dev/mem just to see what’s there.
Expected garbage.

Instead, I found this.

I don't know who wrote it.
Maybe it was always there.
Maybe it wrote itself.

(I didn't change a single byte.)

Looking for a Windows WIN+H-style speech-to-text solution on Linux

On Windows, I regularly used WIN+H to activate speech recognition and dictate directly into any text field. It was a huge timesaver for my writing workflow.

Now that I’ve switched to Linux, I’m wondering:
Is there anything similar on Linux that allows system-wide speech-to-text dictation? Ideally something lightweight and privacy-friendly.

And if that's not possible: can anyone recommend a simple Markdown editor where I could use speech recognition reliably?
Open source tools, practical setups, or personal experiences are all very welcome!
