My two-tier A.I workflow: frontier thinks, MiniMax (open weights) does the heavy lifting

Everyone assumes you need the most expensive model to write good code. They are wrong. I have spent the last year building a CPU inference engine from scratchno PyTorch, no TensorFlow, just C and x86 intrinsics. Along the way I learned something: the model that understands you is not the same model that should write your code.

2025: Fighting Banks, Writing C, and The Great Untangling

Looking back, 2025 has been a good year. Actually, it has been a transformative one.It was a year defined by taking control, whether that was taking control of my code by removing bloated frameworks, taking control of my rights against a billion-dollar bank, or simply having the time during the strike to rethink where I want to go.Here is the breakdown of a very busy year.The Legal Battle: David v...

Reflecting on 2024

Heres my rundown:Mortgage PaymentsI stayed aggressive with my mortgage payments this year, aiming to chip away at my debt as much as possible. Im happy with my progress and might slow ...

The year 2020 has finally come to an end. What a year. In this blog, I want to share what I did, what I learned, what I have transformed into, and what I plan to do in 2021.The year started well, with a bunch of well-paying clients. ANTSAND agency was taking off. By March when covid-19 started to take a hit, things started to slow down. It was during this time I focused all my attention on develop...

Why I’m Doubling Down on C in 2026

It's 2026, and the hype around memory safety is deafening. The industry consensus seems to be that C and C++ are archaic, "unsafe" languages that we need to abandon immediately. There is a growing chorus pinpointing that the majority of CVEs (Common Vulnerabilities and Exposures, the standard system for cataloging publicly known security flaws), from databases to the Linux kernel and even Git, st...

The Great Untangling: Why I Ditched Vue, Node, and Microservices for Pure JS, PHP, and AI

I have been developing Antsand since 2014.

Antsand has survived multiple eras of "the next big thing." By 2021, the application had matured into a complex beast powered by Vue 2 on the front end and a ...

The 3rd Week of January

17 Jan 2021 by Anthony ShivakumarThis past week or so I have been doing good energy-wise. One being, I can get up very early. Anywhere between 4:00 am and 5:00 am. I do not put an alarm. I get up organically. I love it. After I get up, go to the washroom and wash up, I then sit and do the Wim Hof breathing exercise. It is a great way to start the day. A bit of deep breathing, yoga, and some medita...

The importance of priority #1. What is ANTSAND and why is it being built?

ANTSAND first started as my personal dairy to keep track of my life. At one point in time, I did not wanted to use any Social media sites. I wanted to only use the one I created. I think the creator in me thought, if I can build one, I will build one. Why do I need to use other products. This idea has still not completely grown out of me. For the most part I am vey much a maker.I have been working...

Progress on Drones

I did not write yesterday's journal. Today and yesterday I woke up at 430 am. This is so that I can squeeze in the Wim Hof Method in the morning. I want to get into the practice of breathing, meditating yoga, and perhaps even cold showers. My eating habits too, have been improving. Though today I did skip lunch. I had a slight headache and my left eyes were hurting. Plus I woke up at 4:30 am so I ...

A lazy day

Today, I got up early and worked on some client work. I felt very bloated in the morning. A lot of burping. I also sent a mail to a potential co-founder on starthawk. I most likely will need to look for a co-founder for ANTSAND. Will need someone who can take care of sales and marketing.We then went for a walk followed by a run round the park. The distance covered was approx. 2.7 km. I beleive I w...
