Re:Ask HN: What are you working on? (March 2025) on Sunday March 30, 2025 @08:20PM (#43529246)
I am working on this mobile app that is a cross between karaoke and musical instrument practice. Through playing music for a long time, I realize that playing with a band or with the actual song is important to get a good feel of music, specially for starting musicians. Hence the app. Currently I have Nepali songs up. I am finding it difficult to get more subtitle files or generate them quickly (for lyrics layout). Through this I would want to ask how I can quickly generate lyrics file. I really would appreciate the help.

Re:Ask HN: What apps have you created for your own use? on Wednesday December 13, 2023 @07:58PM (#38636466)
25 years ago I needed an app that would transliterate my writing in English to my native language (Nepali), as I did not know how to type in my native language (which I still don't). So I made a 1 person use transliterater. The fonts used for my native language then were mostly ascii fonts with typefaces changed to characters of Nepali. When unicode became more common, then an app that would change from those ascii fonts to unicode. Then I needed units converter as Nepal uses different units of measurement compared to metric as local levels. Hence unit converter for myself. Few more applications on the way, but most have been replaced by Google. In the last 4 years I have moved away from programming to being a full time farmer. Here I needed simple app that would take market data from past years to figure out when I would get the best price for a crop. Hence I made one for myself that would aid me make my crop calendar. Now working on a simple 1 person app for a crop calendar.
Re:Ask HN: Coolest thing you learned in 2023? on Thursday November 09, 2023 @07:36PM (#38213394)
Coolest thing I learned is to clone trees. Roughest thing I learned is that most people who talk about climate, don't really want to plant trees. They just want to talk about it.
If you checked out all others maybe you want to check this one too. Its in Nepal and pioneers of various tech in cataract surgery -- https://tilganga.org/ Their number of treatment is pretty impressive (73,49,257 is their current count of people treated.)
Re:Ask HN: What's Stopping You from Blogging? on Saturday November 05, 2022 @11:08AM (#33482191)
I wrote and made collection of stuff, but literally nobody read in last few years. Realized blogging (or making anything on the web) comes with a lot of marketing. Hence found text files to be better for note to oneself.

Thank you... Will do.

Ask HN: Please suggest an open source project work on

I am looking to work on open source pakcages or tools that are required, but do not have people working on them. Small tools that make life easy for all. I would like to take up one such project and maintain it. Anythin is Python would be good for me. Please suggest how to find such project? Or suggest some package I should look into.

I have started planting local fruit trees with an aim to plant 120,000 local fruit trees in the next 3-5 years. Currently I have reached 3000 in the last 5 months, with another 1000 in polybags.

Leaving programming after 25 years of it, I wanted to do something that will help world be a better place even after I am gone. Trees have always appealed to me. Hence local fruit trees -- sell fruits to run farm once fruiting happens in a few years. Local plants are localized to climatic and soil conditions of the area thereby requiring the least nutrition, water and care.

Its going to be a bit slow from here for few reasons, I have to learn to grow saplings faster and out of season, make fertilizer year round and figure out how to ensure plants are growing. I have figured out some of it, but financial resource crunch will hit me in next 6-8 months. So now trying to come up with ways to handle that.

Help in any of the above is extremely welcome. Does anyone feel social impact funds will want to look at me?

My daugther(18) and I(47) create a comic series at https://www.instagram.com/arghhhcomics/. We use Inkscape and Gimp for them. Now we have animated series coming up, called Misunderstood, where daughter is exploring blender. She is just starting, but loving it.
Having mentored quite a few gifted science students, the best thing that I have found is to give them a problem, give them a bunch of things and tools that they can break and tell them find a solution.

Find time to discuss various solutions or find mentors for your child who can do the same. Let the child understand more, not by making, but by breaking the problem down to the smallest units possible and see the connection.

With the same philosophy we are working to build one room labs in public schools in Nepal called tinker lab (www.tinker-lab.org)

Here is a list of things I have been doing from the time I left programming 2 years ago, roughly having worked for around 24 years. I was left with lots of time and didn't want to work only in one thing like programming before. So I got into small projects that meant something for me. Might be of help.

-- Learning music for last 4 years, mainly to get into a hobby. I put in about 1-2 hours of practice per day. Thinking of building a course for people with absolutely no prior knowledge of music, but I have not started yet. Have got a mindmap going here - https://www.viewpedia.org/musicCourse-map.png

-- Mentoring, at NYAS ((www.nyas.org) and invidiually. Perfect as it does not take too much time, but connects to lot of young minds. Hope to increase and maybe we should create a network of mentors as someone suggested being mentor in the comments. I have not found a mentor network yet.

-- Lokopakar (www.lokopakar.com) - for mentoring and another unique program called Strength Together, that is a peer-to-peer network to help adolescent girls in developing countries overcome their feeling of "I am not Enough"

-- Tinker Lab (www.tinker-lab.org) - I found a group of guys who were into breaking things apart and seeing what was inside and trying to put it back (never really making it). We are now working to make a lab for public schools in Nepal where young, eager, self learning students to do the same. The first lab is coming up within the month.

-- Farming, fruits for fun, vegetables commercially. Now thinking of adding bee keeping and a farm stay program. I spend only the weekends on it as others handle everyday work better than I.

-- Viewpedia (www.viewpedia.org) Still left with time as I gave up social media and most of TV. So learning about my own culture and building a website to provide collection of youtube videos of mostly unwritten Nepali culture. Currently focused on music and dance.

Not only language barrier, many pieces of great music and dance, specially from oral cultures like mine, go unnoticed most of the time.

Few songs to listen for the added variety and by local singers from Nepal:

I have started making a Visual encyclopedia of unwritten and undocumented cultures of the world, currently focusing on Nepal. http://www.viewpedia.org

Listing of Over 60 varieties of Nepali Music

I made a listing and links to sample videos of over 60 different varieties of Nepali music at http://prjoshi.com/music-list/This is a whirlwind tour of Nepal through its music and dance from East to west, North to South and communities. Please listen and provide feedback.While making this list I realized that Youtube is a treasure trove of contributions by people of their native culture as...

Ask HN: What are new Tools to help create online course?

I have been looking at newer tools that people have posted in Hacker news to use them in creation of online courses. I hope to create an online course in Music using these newer tools. More than that I think it would be good to get a listing of tools out that have potentials to used for online courses.Just to name a few that I have seen: Barbra -- https://barbra.io/ -- to share notes among...

Thanks. Looks good, will definitely check it out.
how about building a social platform and further learning site for serial entrepreneurs?? Serial entrepreneurs get together to test ideas, projects, etc... They learn mainly by seeing what others are doing and sharing thoughts. I go to sites to learn something, it is designed for someone just starting out. I want to talk to fellow serial entrepreneurs who are looking at various ideas, but don't know where to meet them and how. Even sharing of visions and opportunities that serials entrepreneurs see could be really insightful not only for themselves, but for anyone who are looking at what is going to happen next.
Re:Ask HN: What you have automated with Python? on Tuesday May 16, 2017 @06:44AM (#14348611)
We, meaning 3 of us, have automated a greenhouse using Python code running on a raspberry pi -- this includes getting data from sensors within the greenhouse (temperature, humidity, soil moisture, soil temperature, carbon dioxide), from an accurite 5 in 1 weather station outside, and then running fans (intake and exhaust), water pumps and sprinklers, camera, etc... and pump data to web, so that we do not need to be present to see what is happening inside the greenhouse. No code is production ready, but we have had 2 good vegetables crops from the greenhouse already. The problem we working on is presented here : https://medium.com/@pravenj/a-bucket-a-day-a-hack-in-agricul...
Re:Ask HN: I'm out of ideas for side projects. Help please. on Wednesday February 01, 2017 @08:12PM (#13547176)
maybe hack a project for extreme affordability from hackproject.org? More problem discussion in the slack channel where you can self-register hackprojectorg.herokuapp.com. Even old problems or simple problems that you might have not even looked at with passing eyes could have dramatic effect for extremely rural areas and what the UN calls the frontier worlds.
Re:Ask HN: How to learn new things better? on Monday January 02, 2017 @08:29AM (#13301026)
My methods are divided into 2 -- binge and short bursts. In both I tend to use open ended questioning, perspectives and reflections as ways of enhancing the learnings.

Binge is method I use to learn a lot about a topic in the shortest period possible. I start a binge with either trying to understand more about a topic or to try an see whether a hunch I have in regard to the topic is well worth following.

Short burst is a method I use to learn something more deeply and more over a longer term. In this I put in 5-10 minutes 3-4 times a day maybe for a period of about 2-3 weeks. Then rest and reflect for a couple of weeks and then go through the cycle again.

I have written a post about it here : http://prjoshi.com.np/2017/01/02/on-learning/

Hope it helps.

Would love to test it. Where do I use it from???
Could collaborate on a project that I am contemplating as well as testing out bits and pieces. One thing though I probably am located very far from you and the project would be more of a research project. If interested a few rounds of emails might become a path to follow.
