In this video I will present a case study of a complex performance issue where the initial symptoms pointed somewhere else than the root cause. Only when systematically following through the troubleshooting evidence, we get to the root cause of the problem. This session aims to help you understand (and reason about) the Oracle’s multi-process & multi-layer system behavior, preparing you for independent troubleshooting of such complex perfor..

Last night I was playing Maquette and I got stuck on the final level (called “The Exchange”) for a really long time. I was at a place with some towers with crystals above them and I had opened the doors to the first tower; Inside was a switch. Flipping the switch made a bunch of … Continue reading Stuck on the final Maquette level

WFH Day 353 I didn’t sleep too bad last night. I got up at around 7:15 am, made myself a coffee, and continued to read my current book Gerta . I’m a slow reader, and if I don’t put time aside for reading, I will never finish any longer book in a finite amount of time. Reading in bed at night is something that doesn’t work for me. I usually fall asleep pretty quickly, and then my Kindle, or even worse, my iPad, falls to my face. If I start..

We're excited to announce that we’ve redesigned Snyk's issue cards to significantly improve its usability and value. It’s more than a fresh coat of paint and we haven’t taken anything out, but we’ve added value and feng shui’d the card considerably.

This post is the part of Scraping Series. Usually, when you start developing a scraper to scrape loads of records, your first step is usually to go to the page where all listings are available. You go to the page by page, fetch individual URLs, store in DB or in a file and then start parsing. Nothing wrong with it. The only issue is the wastage of resources. Say there are 100 records in a certain category. Each page has 10 records. Ideally,....

Today’s mandatory reading is How I cut GTA Online loading times by 70% . As someone who’s been fighting the protection/obfuscation cat & mouse game for twenty+ years, let me tell you one thing. The way this guy reverse-engineered parts of the GTA5 codebase and then proceeded to single-handly triage and fix a long-standing (7+ years) performance issue is simply mindblowing. All he had to work with were heavily obfuscated dlls. This also ..

I’m really interested in privacy and how my data are collected, used, stored and just in general exists. While I think of my data as mine, the more I think about it, the hazier I am. I think defining ownership more clearly will help me think of what’s possible and then what’s also appropriate and reasonable to do with data. Limits to using my data I was reading about how Google is changing Chromium to remove and restructure some features....

The Harrell-Davis quantile estimator is one of my favorite quantile estimators because of its efficiency . It has a small mean square error which allows getting accurate estimations. However, it has a severe drawback: it’s not robust. Indeed, since the estimator includes all sample elements with positive weights, its breakdown point is zero. In this post, I want to suggest modifications of the Harrell-Davis quantile estimator which inc..

Last weekend’s reading list also included Taking Back Our Privacy , yet another 1 New Yorker piece but this time signed by Anna Wiener. This article is a long-read on Moxie Marlinspike, co-founder and CEO of Signal. Moxie is a childhood nickname. That alone signals (pun intended) an original personality. I mean, how many times have you heard of a CEO going by his childhood nickname? Indeed the personal story of Marlinspike, along with..

I've just finished reading the very enjoyable Almanack of Naval Ravikant. It's one of those rare books that made me want to read it as slowly as possible so I could really take in all the bits that resonated with me.

Von Neumann architecture This basic model of a computer as a processing unit that receives input, communicates with a memory and produces output is known as the von Nuemann architecture named after the first computer scientist John von Neumann. In this architecture, the processor itself consists of several specialized parts: The arithmetic logic unit (ALU)-the central processing unit capable of performing mathematical and logical operations..

As a career changer and a black woman, transitioning into tech has been a challenging and so far, a rewarding experience. Prior to working at Thoughtworks, I worked for more than a decade in the legal industry assisting Intellectual Property litigation attorneys. In 2016, I decided to learn to code and attended an online coding bootcamp while I was working full time. It was definitely effortful learning to code, however, I wanted to make th..

When most people think of three dimensions, they think of three positional (spatial) dimensions. Up & down, left & right, forward & back. I was thinking - instead of a positional dimension, what if we used something else that we can perceive such as color?

4300 words, 14 minutes. This post was circulated privately in April 2020. Three months later the government announced that Huawei 5G equipment will be removed from the UK by 2027, a reversal of their previous position. I’ve updated the timeline with that development. Otherwise, the text is almost unchanged from the original. Keep that in mind. It follows my July 2019post on the consideration the UK and its allies are giving to Huawei as a ..

I was asked during a recent panel on Clubhouse about assessing culture fit. What was once an innocuous term for “people who aren’t terrible human beings” has quickly become a trigger for exclusivity, gate-keeping, and homogeneity. Here are my thoughts on how things got out of hand with this hiring practice.
