Something really handy

mpi2-report.tex -- The MPI Specifications.

I just finished modifying my prime number finder (one that's implemented on a beowulf cluster at the advanced science and technology institute (ASTI)) which also happens to yield mind boggling results.

with the previous runs i have done, i get times of around 190+ seconds, finding all the prime numbers from 1 to 999999. and that was already surprising, considering that if you run it on one computer, it's really going to take more time than that. but with the modifications in, finding all the primes from 1 to 999999 only took about 5 seconds!! that was using just 5 nodes, and a chunk size of 10000 -- this may be confirmed, and test results as soon as available may be obtained by request via email. now i have to find a setup where the cluster is really homogeneous, and where the loads of the nodes are unstable (or where the nodes are not dedicated for the cluster).

anyway, more news to come as my sem draws to a close. i might be blogging more often to let people into my life as i rest. :) keep chillin'... :D

Writing Again

It's 2019 and I just realised that I've not written on this blog for a long while. I feel a little bad about this so I'm picking it back up again. More importantly, I've limited my social media to just Twitter (I've deleted all my Facebook-related accounts) and will be writing more on the blog instead of engaging in other social media sites. If you want to reach me directly, you can also reach me through my keybase.io account for encrypted communication. If you have my phone number, you can also contact me through Signal. Quite a number of things have happened in the past few years and here's a quick update on things that I can share:

I've been working on XRay, a function call tracing system now part of the LLVM project. This took a good two and some years of my time at Google.Most recently I've moved to the Chrome Operations Team still here in Google Sydney. I can't give specifics yet of what I'll be working on, so stay tuned.There've been c…

A Passion Project

I was so moved today by the prospect of a passion project that I took some time on a Friday night to get it done. Let me present the #RedJeans project over at redjeans.org. I've found myself wanting to work on a project that came purely from the heart and one that was very dear to me, something that is personal, and connects with a larger community of people in the world.
The idea for redjeans.org came to me as a hint when I was writing up my reflection for 2018. I realised that I didn't spend quite as much time identifying with and working with a community. I did a bit of soul-searching and found that one of the activities I really enjoyed and cherished in years past is donating blood -- and I keep wondering why not more people do it. It was an idle thought but then a conversation with someone where I described why I wrote down "donate blood more often" in 2019 became an idea where instead of just me doing it, how about if I get my friends to do it too?

I left it a…

From FOMO to JOMO

Until very recently I believed that I needed to be on top of the latest news and happenings not only in my field (computer science and software engineering) but also in as many things as I can be on top of. This meant subscribing to all sorts of magazines, newsletters, YouTube channels, Twitch streamers, watching TV and live sport events, etc. — I was on top of a lot of the latest happenings, trends, news, interesting developments. I was having fun and I felt busy. What I did not feel was particularly effective nor productive. I felt like I was consuming so much information with the thought that it might be useful someday. When I was younger this wouldn’t have been an issue but I realised that ever since I’ve started taking stock of what I’ve been spending my time on, that a lot of it I’ve been spending just staying on top of things that I really didn’t need to be on top of. This article is about some of the realisations I’ve made in the course of exploring this issue of “FOMO” or th…
