“It often happens that two schoolboys can solve difficulties in their work for one another better than the master can. The fellow-pupil can help more than the master because he knows less. The difficulty we want him to explain is one he has recently met. The expert met it so long ago he has forgotten it.” — CS Lewis, The Weight of Glory (quoted in Show Your Work!) I loved that quote. It made a lot…
It became obvious within five minutes that my friend was going to lose the chess match to a six-year-old. When the inevitable happened, everyone celebrated the kid. A few moments later, they congratulated the parents too. Interesting. If the kid had been eight years old, would people still congratulate the parents? What about ten? Fifteen?

By default when we run a process inside a Docker container, it is run as the root user, and that’s all right; after all, we are talking about inside the container, but as far as the host machine is concerned, what user is running the process? Spoiler alert: It is the same root user as on the host. Let’s take a step back and try to understand what’s happening. So I created a fresh VM server and…
At one point or another we’ve come across a command line that looked something like the following sh program.sh 2>&1 In general we know that it redirects the error stream to the stdout stream, but let’s dive a little bit deeper today. Let’s run a simple sleep process and let’s open another terminal to find the process id with ps aux sleep 5000 ps aux | grep sleep And that should give you an output…
I had decided a long time ago, that when I build my next PC I would make the current PC a server. But I was unclear about how I was gonna go with it, I was thinking of maybe installing Ubuntu on it, and install all the services(maybe all the services in individual dockers) for safety reasons. But then, that’s when my friend introduced me to Proxmox. To put it simply with proxmox we can create…

Installing tmux I usually spend a lot of time here, to get the perfect setup, something like - tmux + tpm + zsh + tmux-resurrect + zsh autocomplete. This time I’m just going for the vanilla experience, just tmux alone. One of the reasons is I keep finding myself with new OS installs, new temp laptops, new servers, and I can’t afford to set it up in every place, so I’m going to try to limit my…

Not to brag but since this is important to the context, let me make something clear - I considered myself an above-average coder, I have released a few noob android apps, have won a couple of Hackathons, and have also contributed to some open source.
