arkokoley··on I am building a browser for agents
very interesting but similar to the others out there but privacy focussed. My take is on a better UX around the agents with better agency delegation.
arkokoley··on Ask HN: What Are You Working On? (July 2026)
I have been working on a AI native browser = WebMCP is first class and the in-app agent uses it to do tasks.. not the same as a slapped on chat sidebar. also MCP actions are lightning fast.. so i use it via my Hermes agent.

arkokoley··on Launch HN: Societies.io (YC W25) – AI simulations of your target audience
This is a fascinating project! It's exciting to see the application of multi-agent simulations to a real-world problem like optimizing marketing messages. Your approach of grounding the AI personas in public data and focusing on social influence is very insightful.

I recently authored a paper on a related topic that might be of interest, particularly concerning your challenges with accuracy and long-term simulation stability. Our work, "SALM: A Multi-Agent Framework for Language Model-Driven Social Network Simulation," introduces a novel framework for integrating language models into social network simulations.

I specifically focused on achieving long-term temporal stability in multi-agent scenarios.[2] A couple of our key contributions could be relevant to your work:

I developed a hierarchical prompting architecture that enables stable simulations beyond 4,000 timesteps while significantly reducing token usage.[3]

To address memory growth and maintain agent consistency, I implemented an attention-based memory system that achieves high cache hit rates with sub-linear memory growth.

I also established formal bounds on personality stability, which could be a useful concept for ensuring the accuracy and predictability of your AI personas over time.

Our validation against SNAP ego networks demonstrated the capability of our framework to model long-term social phenomena with empirically validated behavioral fidelity.[3]

It seems like there's a lot of synergy between our research and your product. I'd be very interested to hear your thoughts on our paper and explore if any of our findings could be beneficial for the continued development of Artificial Societies.

Here's the link to my paper: https://arxiv.org/abs/2505.09081

arkokoley··on Ask HN: What are you working on? (February 2025)
Working on a resume editing tool for rapidly applying to a large number of jobs. The basic idea being that resumes should be tailored to the job being applied to. In this tool, you put in your resume, add in other details regarding your background, projects and other things that you might not put in the resume. You do this once.

Now you paste in the job description, we use an llm to generate a new resume grounded in the details you added earlier. You get a pdf that you can submit to the job application.

Have you tried Authority Rank as a substitute for PageRank? https://link.springer.com/content/pdf/10.1007/978-3-030-6097...
arkokoley··on Ask HN: What are you working on? (October 2024)
I have worked on social dynamics on social media particularly how why certain kinds of content/people become viral. To that end, I have been working on a large-scale simulation that simulates twitter. It pulls data from a random distribution, generates users with specific interest vectors. its modelled as a Agent based modelling with the users as agents, posting every timestep, reading content posted by others, recommended to them by a recommendation engine. all of this this then generates data for research.

Hi all, I'm an ex-Microsoft SWE currently working through my PhD in Data Science at Boston University. In the past I have worked on numerous projects with Large Enterprises and small startups. I am a one man machine, capable of working on Front-end, backend and any devops aspects of any business. I'm also a Data Scientist in training so interested in data-sciency roles too!
arkokoley··on Uber and Lyft’s new road: Fewer drivers, thrifty riders and jittery investors
I used to do that with QuickRide in Bangalore. Very popular and fairly simple to use. As a rider, you can put up your origin and destination points. You are shown people with cars who have a high overlap with your origin-destination route and you can send them requests to join. Usually 1/4th the price of a cab and the app has information about where each rider/car owner works (mostly MNCs), that works as a trust factor.

arkokoley··on Ask HN: Does Microsoft use Teams for internal comm?
I used to work for Microsoft and our team's morning rant (on Whatsapp) would start with MS Teams not working. Often meetings would be stopped because Teams hung up for the person who was presenting. And the Teams/Skype Infra team were the slowest in the world to respond to any requests!

The article mistakenly calls the Haken Kreuz as Swastika, confusing the Hindu symbol for prosperity with the Nazi Haken Kreuz. This should be corrected.
arkokoley··on Show HN: I made a little digital circuit simulator that operates on PNGs
Have you tried http://Circuitverse.org?

It's by a friend who initiatally built a digital circuit simulator and then turned it into a GitHub like collaborative website.

arkokoley··on Ask HN: How to save bookmarks locally including searchable content?
I'm building my own solution because nothing like this existed to my knowledge.

It currently supports webpages, pdfs, personal notes, images and twitter.

arkokoley··on Challenge: can you view my source?
Yep.. throttling the connection worked for me too!
arkokoley··on Ask HN: How do you organize yourself ?
I tried out a bunch of tools. The calendar, markdown files, todo apps, I tried them all. Nothing quite stuck around.

So I decided to build a tool on my own with help from a friend. Add items to the list board, and they get added to my calendar as and when time is available.

arkokoley··on Ask HN: What are some tools / libraries you built yourself?
I built a Pdf viewer library for VueJS based on Mozilla's PDF.js. PDFVUER - https://github.com/arkokoley/pdfvuer

I also built a time tracker library that tracks how much time was spent on the current open tab. It also detects when the user moves away from the page or comes back.

For a GIS project, I needed to extract county level data from NASA's MODIS dataset. Wrote a bash utility to do that: https://github.com/arkokoley/modis_county_cropper

Also wrote a boilerplate latex template for Academic homework: https://github.com/arkokoley/latex-homework-boilerplate

arkokoley··on Ask HN: What are the best books to read in 2021?
The Power Law of Information: Life in a Connected World by Srinath Srinivasa

https://www.goodreads.com/book/show/8449969-the-power-law-of...

A 14 year old book that is still as relevant as it was when it was published. Prof Srinath gives you a crash course in graph theory and network science while still making sense to people who have never heard of either graphs or networks. The only instance when I felt that I was reading a 14 year old book was while reading about the prevalent USD-INR conversion rates. This makes me come to the conclusion that one of the following must be true: Either the book was way ahead of its times; or we haven't made much progress in the last 14 years with respect to communication technologies. Since the latter is obviously false, the former must be true!

A absolute must read if you are interested in the working of networks science and how the interconnectedness of the world affects us all!

Added points to Prof Srinath for pointing out the defintion of "memes" :-D

arkokoley··on App Review process updates
We think we are creating a softer and kinder world, but the opposite is true. If a guideline is actually an order, what's an order?
arkokoley··on Ask HN: What city do you plan to move to if all companies move to WFH?
If my current MNC turns WFH full time, I plan to shift to Goa, take up a house by the sea, wake up to the breeze and take a dip in the sea once I'm done working.

Currently a Software Engineer in Bangalore, India earning approx $30k per annum

arkokoley··on Ask HN: What's your quarantine side project?
Taking my master's thesis project and turning it into a Analytics SaaS for Social Networks. My master's thesis[1] was a generic model for social capital based on Engagement and results in metrics of engagement and influence in a social network. For testing this out I built a social network[2] for sharing preprint and published papers. I am now generalising the metric calculating backend and providing it as a an API+Dashboards for other social networks who want to understand their network structure and identify members who enjoy a lot of attention, those who might not be popular across the entire network but enjoy a cult like status amongst their followers and people who participate the most on the network.

arkokoley··on Merry Christmas HN
Merry Christmas and Happy holidays!
arkokoley··on Blogging Like a Hacker (2008)
True. Zense Dev (we are a student software development group based out of Bangalore, India) uses Jekyll to render its main website[0] which includes a blog, a list of projects, lists of events happening and a list of the members of the group. We even have member pages and the blog posts written by that member show up there.

arkokoley··on Show HN: Personal Management System
I always felt the same too!
arkokoley··on Writing Tool for Focus and Creativity
I thought this was a joke but damn! It sure does force you to focus.
arkokoley··on Ask HN: Do you have a personal website that isn't just a landing page?
I have one. It's just my poems, what I build, what I talk about and what I blog about.

arkokoley··on 339 Bytes of Responsive CSS
Very interesting point. My thoughts were along the lines of "underlined links look bad". I did not realise this could be an accessibility problem.
arkokoley··on 339 Bytes of Responsive CSS
True. But reading lines longer than 90 char is difficult. Probably multi-column text is the way to go.
arkokoley··on 339 Bytes of Responsive CSS
Imports would be a boon!
arkokoley··on 339 Bytes of Responsive CSS
True. Grid still has a long way to go. Flexbox works as a nice alternative in the meanwhile. However, the semantics of the flex is too confusing and cumbersome.
