With more than 10 years of software development experience, I have developed a strong foundation in cyber-security, web development, machine learning, and cryptocurrency/blockchain. My background in Astronomy and Astrophysics (H. BSc and MSc) has provided me with strong analytical, mathematical, programming, and communication skills.

In the cyber-security domain, I have spent four years mastering Golang, PostgreSQL, Grafana, and GitHub Actions. At Arctic Wolf, I was a team lead for the past two years, where I managed five developers. I guided the team on a modularization project of our end-point Agent, and where I managed the biannual release cycle of our software. My back-end web development experience spans five years, where I have worked with Node.js/PHP/Golang, MySQL/PostgreSQL, Redis, RabbitMQ, and Docker/Docker-Compose. I also have more than a decade of experience in scientific programming, using FORTRAN, C/C++, Python and Bash.

Some of the work I am most proud of includes the parallelization of the SWIFT numerical integrator, a ML document classifier for OCR text, my contributions to the Bitcoin code base, and my entry in the 2016 Halite AI Challenge where I ranked in the top 3%. To see my ML portfolio, visit: huggingface.co/spaces/ccapo/portfolio

Outside of my professional career, I am passionate about pushing the boundaries of my personal projects. Currently, I am building a high-altitude balloon equipped with a Raspberry Pi and an Arduino. I also enjoy crafting rogue-like video games, blending creativity with interesting game mechanics. For a glimpse of my work, visit: github.com/ccapo

The University of Toronto (among others in Canada) had SLOWPOKE reactors on campus.

When I came across the site years ago, I saved a copy of it so I could run it locally in my browser. Only later did I realize there was a GitHub repo: https://github.com/cantonbecker/bitcoinpaperwallet
The detector could just be the entire galaxy, it doesn't have to be an artificial construct. To your question, you have already seen it, hiding in plain sight.
Re:Ask HN: What are you working on? on Thursday January 14, 2021 @07:34PM (#25785266)
I wrote an in-memory, write-only caching library for C++:

https://github.com/ccapo/ephemera

I am planning on using it for a game server, to keep track of player scores.

Re:Ask HN: What are your favorite roguelike games? on Sunday November 22, 2020 @12:46PM (#25179348)
- Jauntropper: Mission Thunderbolt, and the sequel Mission Firestorm

- Pixel Dungeon

- NetHack

- Moria

- Rogue

- Games made for the annual 7DRL challenge

Was it a Jamaican and Hungarian restaurant, because that would be awesome! I would try a Jerk Chicken Goulash in a heartbeat.
Help! Help! I'm being repressed!
Re:Kahan Summation Algorithm on Tuesday December 24, 2019 @12:25AM (#21870083)
I remember reading about Kahan summation, and I naively thought it would help improve the accuracy/consistency of a n-body code I was using for my PhD. I was trying to resolve a discrepancy between summations when performed serially versus in parallel using OpenMP. In the end I abandoned the approach, since it seems the issue lay elsewhere.
Thanks, I will have a look at it.
Thanks for sharing that information about Differential Programming, I was not aware of its existence. I'm curious if this approach will help solve some problems I am investigating.

Do you have any suggestions for papers or libraries that implement Differential Programming?

Correct, and since that bias is towards larger NEOs, which are relatively easier to detect then smaller objects, they can be reasonably confident about that estimate. It is the medium to small size NEOs that are the most worrisome. They are harder to detect, and hence harder to estimate how many are out there.
Re:Ask HN: What do you do with your Raspberry Pi? on Monday June 24, 2019 @10:21PM (#20270623)
* I made a Raspberry Pi Zero W version of this baby monitor (https://kamranicus.com/guides/raspberry-pi-3-baby-monitor)

* I am using a Raspberry Pi Zero W + Arduino Pro Mini, with a GPS, Sensors, Camera and Radio for a High Altitude Balloon (HAB) project (https://bitbucket.org/ccapo/habpi/src/master), launch pending. A friend is also launching a similar project (https://bitbucket.org/peterkingsbury/neopi/src/master/)

* I am using a Raspberry Pi 3 for RetroPie

* I have a Raspberry Pi 3+ for development purposes, mainly the HAB project since developing on a Raspberry Pi Zero is quite slow

Re:The sun is stranger than astrophysicists imagined on Friday May 03, 2019 @01:55AM (#19815910)
The Parker Solar Probe is currently in orbit around the our Sun, with its main mission to determine why the Solar Corona is so hot.

So they haven't just stopped talking about it, they are patiently waiting for the data so they can analyze it.

I wholeheartedly agree with this assessment. I think the culture is extremely toxic, and it pushes out many promising students and researchers.
