Over the past 2 years, only 3 books got me reading until their end. The first, titled Mountain Beyond Mountains by Dr. Paul Farmer, a book chuck into my hands by a close friend. Unbeknownst to me, it was the book that inspired and got me moving out of nursing to explore technology with its […]

Scaling
Listened to this podcast while commuting https://twimlai.com/twiml-talk-269-advancing-autonomous-vehicle-development-using-distributed-deep-learning-with-adrien-gaidon/ A research scientist in Toyota working on deep learning simulation for high image resolution needed to learn dev-ops to scale their testing. Tools used: docker, kubernetes, Beegfs. Why beegfs though? He did mention that there were db that could store up to 700gb until a point that they […]
Distance detector
Tutorial for above is here. Tried the first time and fried my usb-c, wasn’t reading that I needed to ground them… Now it works 🙂 Adjusted the frequency much higher for nicer sounding tones. Tried to use the frequency for notes C – G, and it sounded pretty jarring to the ears. The electronic buzzer […]
Crash collision sensor
Having some time to myself to play with some new sensor, the circuit is pretty straight forward, waiting for my raspberry pi in the meantime.. SensorVCC >> 5VGND >> GNDOUT >> pin 3
Random reads to keep
Companies that does vulnerability scanning Encrypted Database and todos From the discussions, when a company has a encrypted database(s)– It needs to be backedup– backups needs to be tested and verified using a snapshot on a separate vm instance– if it was encrypted, the generated keys need to be saved– there are ITCP audits that […]
Finding an error in a haystack
Well, today I needed to debug an error on the server. I needed to search the logs to find what the error was. Finding the particular information that I needed was difficult simply because I wasn’t proficient in vim and linux commands, and, the log was more than 20GB of data.. As usual, I looked […]
Jest, Puppeteer or ?Nightwatch
After using nightwatch we decided to switch to using jest and puppeteer for the many more apis and functionalities to support our wordpress plugin and chrome extension. A note here though that puppeteer only supports chrome/chromium. If you need to test cross browsers, nightwatch may be better with their browser drivers. To setup jest and […]
Ubuntu auto script
So I was pretty tired of updating every single server I was messing around with for experimental purpose so I decided to create an auto scripting for the usual ‘apt update && apt upgrade’ command Go to your server Go to the folder where Cron exists. Cron is a time-based scheduler that allows daily, weekly, […]
