"Too many files" error in NGINX

Screener was quite a bit slow yesterday. But more importantly, once in a while we were getting a "504 bad gateway" error.

One thing I remember the most from Max Kanat-Alexander's "Understanding Software" is to never fix a problem until you can reproduce it.

Sometimes people have a very hard time debugging. Mostly these are people who believe that in order to debug a system, you have to think about it instead of looking at it.

[...]

It can be tempting to think that you already know the answer. Sometimes you can guess and you're right. It doesn't happen very …

Trek to Sandak Phu - 11980 ft

Phalut top - with The Sleeping Buddha in the backdrop

This was my first high altitude trek. After returning, I am surprised, it didn't feel that hard. I can to do it again!

Probably the walk on day 4, from Phalut to Aal changed everything. It was a walk I will remember for a long time. That day I saw the valley of clouds. The ocean of clouds floating beneath us. The little hail (kind of snowflakes) particles, flying and sticking to my fleece. Huge vultures flying with their 3ft wide wings.

We saw Mt Everest and The Sleeping Buddha …

Week 16: The 4-Hour Work Week

There have been lots of interesting developments over last few weeks:

Added a WYSIWYG editor (Squire)
Created a new app: DumbFill (RAG)
Had a small family get-together
Caught "The 4-Hour Work Week" bug

While the first 3 were more creative and fun; the last one has been occupying me the most. It is an experiment I would like to talk about.

Warning: I have still read only 50% of the book. Trying to test and apply each page; rather than discarding the weird ideas in the book.

It all started with this Tweet.

Week 15 - PyDelhi

I attended PyDelhi conference this week. It was refreshing to talk about tech, non-stop, for two days.

These are some notes from the talks at the conference.

NetworkX for network analysis

Navya gave a simple and quick overview of the NetworkX library with practical examples. I want to try this library. Though I don't have an immediate use-case, I want to explore something similar for recommendations. Something where I can just define the existing associations. And then ask the library to throw a recommendation based on certain selection. Something as …

Weekly Review 14 - Chennai

I travelled to Chennai last week with my wife and daughter.

We visited temples in Kanchipuram, did some saree shopping, and travelled around the city. I stayed for two more days and visited some listed companies after my wife returned.

I was surprised to see zero encroachment in the city. In Lucknow and most parts of India, the foothpaths are taken over by street vendors. Just outside our house, the street is being encroached by vegetable sellers, cigarette shops, thelas and puncture walas. I filed a complaint. They were moved one day, but returned with two additional gumtis the next …

I was Stuck

I get stuck sometimes. And I can do nothing until I solve that problem.

When I am stuck;
My emails start piling-up;
Pending payments go unnoticed;
People get offended as I don't reply to their DMs;
Meetings as hastened or cancelled;
The error logs start increasing;
All the KMPs take a sudden nose-dive.

I get stuck fixing the music player, while all the guests are waiting for the dinner. I get stuck fixing the page layout in Excel, when it is last week of September and a dozen tax returns need to be filed.

I was in 6th or 7th …

Weekly Review 13 - Flame

My Brother and I were at Flame University last week. We attended Prof. Sanjay Bakshi's course of Case Studies and Business Models.

Prof Sanjay Bakshi and Flame

Sanjay Bakshi Sir's lectures have changed the way we invest.

We always looked for undervalued and unpopular companies going through a transition. We were number guys and focused mostly on financials of the companies. We sold the stocks when they sort of doubled.

Prof's lectures taught us to focus on qualitative aspects. These models help us evaluate the companies better and ride them longer. It …
