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.

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.

restrictions lead to clever and optimized solutions. well done!

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.

Thanks. Interesting, that's slightly less than I expected with 500,000 users!

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.

Sure thanks, Let me know if you have feedback.

I really like the ease of use of the site. It's also very clean. However, when you go into the Linux, there is a bit of latency (very noticeable). I know that it's impossible to remove the latency completely (it is what it is), but is there a way to slightly reduce it?

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?

How does it only work on 8gb of RAM if it serves 500k users (albeit not all 500k at once)?

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!

Trading 0 day till expiry options?


Yes, I know the risk involved. Just 1 or 2 trades per day not more. Always used the amount that I can afford to lose. No gambling.


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


This is a very thoughtful post, and I sympathize with the sentiment, but I don't think it's really about "open sourcing" anything. The same could be said if you spent that time building model trains, working on a car, or engaging in any other hobby.


Agreed. "Open sourcing" means you do it for free but your work benefits others. And you may have an opportunity to pass the torch to others. For hobbies you keep it to yourself. I played an instrument for many years in spare time. I enjoyed it a lot. I eventually gave up, because my life changed and many other things popped up. On reflection, I still think it was an intersting experince for all those years. But I don't feel anything for it now.


Yes, it's not different from a workaholic for example. So in this vein, not on topic, because it's not about the license. Still, it's a good lesson, and is technically an answer to "regretting open-sourcing something" - it's just that OP reconsidering open-sourcing their life, not their software.


>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.

This is a wise conclusion, that I think impacts many people. I know it does impact me. My personal way of going about it was that I was more invested into theoretical, ethical problems instead of my actual life problems that surrounded me. My tech life was vast and colorful, but my real life was barren.


I can imagine that happening when the motivation is external (praise). When I write open-source it's because I have to write it out of myself.

Do I expect praise, kudos, fame, whatever? I do and that happens, I have been hired countless of times because of open-source. Even my friends (!) have been hired because of open-source stuff I wrote and they contributed to.

But the main motivation is internal - I just have to see it take shape. Like a writer who can't resist painting or a writer who can't stop writing.

Do I have regrets still? Yeah because I could have used the time for better things. But that can be said about any hobby.


What you describe is an interesting moral hazard variation: you were disconnected from the positive effects you had on others. All may not be lost: what if you were to reach out to individuals who have enjoyed your work?


Thank you for this honest reflection. A good reminder to think about priorities.
