As soon as I read this

>Shared dev boxes, shell-as-a-service, jump hosts, build servers — anywhere multiple users share a kernel. any user becomes root

jumped out of bed and went straight into webminal.org servers as local user and ran the python code. It says permission denied on sock() call.

Then I tested with local laptop with it:

```

$ uname -a

Linux debian 6.12.43+deb12-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.12.43-1~bpo12+1 (2025-09-06) x86_64 GNU/Linux

$ python3 copy_fail_exp.py

# cd /root && ls

bluetooth_fix_log.txt dead.letter overcommit_memorx~ overcommit_memory~ overcommit_memorz~ resize.txt snap

```

It does provide the root access!

Yes, GIF in PR is really nice in my view too :) Our reproduction runs in a sandboxed per-repo environment that we re-verify the fix in before opening the PR. Would love to have your thoughts on beta and to see how it goes on real world apps. I'm reachable on support AT neverbreak.ai

https://neverbreak.ai that fixes failing CI and opens a PR with _proof_. Most "AI CI fix" tools read the error log and guess a patch. We actually reproduce the failure, fix it then re-run the test in a fresh environment to confirm it passes before opening the PR. Each PR includes a short GIF of the fix working. If the test doesn't actually pass, no PR gets opened. Works with C, Python, Go, Node.js, Java on GitHub Actions and GitLab CI. Currently working with few beta users.

Sure. We had quite a lot of universities and schools used this platform for their classes. I'll be away from system for next 48hrs though.Drop us a mail,will respond.

Actually I opened up GitHub Sponsor just few weeks ago. Few tims i received enquiry from users (professors) who wanted to contribute back.only now i have proper channel to redirect such requests.

Only UML is the resource consuming part kept as option available on request. Rest of them all shared Shellinabox, nginx,Flask and each active user session consumes little RAM since its a shared terminal. Simple `ls /home` shows all other users on that server!

There will be little latency if you access from different region. Server located at Singapore. From India, I checked right now directly via this link https://www.webminal.org/terminal/proxy/index/ I dont see much issue. I use firefox/chrome on Debian. May be try with different browser?

Thanks, most of these came out restriction, we cant afford to throw money on horizontal scaling (adding more server,load server etc). So we kind of forced to try out new things to keep cost affordable. There are many thing left out on above doc: IIRC, we started with openvz and even today our security relies on SELinux, how we remapped user account creation with pre-existing templates for ext4 quota, we moved to xfs because of flexibility. Mysqldb quota/limits, fork bombs by college/school students bringing out docker environment. Old school internet is right term.

Until few days server ago was using 8GB and I did a cost cutting measure and its running on 4GB server for last week or so. :)

In past I have seen around 10 process, but I think with current setup, it could support around upto 20 UML. Remember this runs on the same server where others login and get their normal bash account too. So not a dedicated UML server.

It began as on-prem, Freston hosted in his house (we shared server cost, some people called it crazy, because I sent money to someone I met in Linuxforums.org and never seen this person, even via internet, I trusted him because I know him for few years on that forum) After 3 years or so we moved on to cloud servers. Mostly switching from one infra and another if we get some credits :D Couple of years we had Linode sponsoring those nodes until its acquisition.

>shared screen comms system is outrageously crazy,

Thats Freston idea. I remember our typically chat begins with something like "Hey Laks, Can you see me typing!" ;)

Yes, User mode linux pretty cool project. If I'm not wrong, UML is kind of predecessor to gvisor or firecracker from a different era.

To be honest, I do regret it. After 20 years of working on FOSS projects, I've invested enormous amounts of time, effort, and money into these and other free/open-source initiatives. It was enjoyable initially - there's something addictive about receiving praise from strangers and unknown communities. You keep going because it feels good and you develop a sense of moral superiority. But years later, when the people closest to you are no longer around - you pause and reflect on how much energy you devoted to random strangers instead of those who shared your life. If I had invested even 1% of the time and effort I put into FOSS projects into my relationships with loved ones, they would have been so much happier. Now I'm left wondering what the hell I was doing all those years https://giis.co.in/foss.html

Looks nice. Is it possible start_chrome() with specific chrome browser profile name or re-use existing open firefox/chrome browser session and launch a new tab with specific domain?

If you have recent kernel version and using ext4, case insensitivity for specific directory can be enabled using casefold feature. See https://unix.stackexchange.com/questions/558977/how-to-enabl...

Just a background for people who don't know about Delhi CM:

- He came to power by using India Against Corruption movement which was led by Anna Hazare https://en.wikipedia.org/wiki/Anna_Hazare

- Once capturing power, he kicked out founding member like https://en.wikipedia.org/wiki/Kumar_Vishwas and his close associates like https://en.wikipedia.org/wiki/Yogendra_Yadav and many others & became de-facto leader of this party. (Now his wife seems to chief of this party)

- In this specific case, Indian Investigators summoned him 9 times and he refused their request for meeting and finally he was arrested after court refused to stay any arrest by Investigators

IMHO, he should have corporated with Investigator, rather than trying to keep them at bay.

PS: I used to be huge supporter of him during those time (2011-2014) and even donated small money (my only donation to any political party till now) while he formed the party (which I regret now).

PS2: Interestingly, his mentor Anna Hazare (who stayed away from his political party and doesnt have political ambitions) said "His arrest is a result of his own actions" https://www.thehindu.com/news/national/result-of-his-own-act...
