Analysis of Chromium issue 1196683, 1195777
On April 12, a code commit[1] in Chromium get people’s attention. This is a bugfix for some vulnerability in Chromium Javascript engine v8. At the same time, the regression test case regress-1196683.js for this bugfix was also submitted. Based on this regression test case, some security researcher
AWS Startup Security Baseline (AWS SSB)
AWS Startup Security Baseline (AWS SSB)
The Amazon Web Services (AWS) Startup Security Baseline (SSB) is a set of controls that create a minimum foundation for businesses to build securely on AWS without decreasing their agility. The controls in this guide are designed with early startups in mind, mitigating the
Ctrl-C: Why Programmers Can’t "Reset" Programs With Ctrl-C, but Used to Be Able To, and Why They Should Be Able to Again
When a programmer presses ctrl-c inside of a command-line program, that program should stop what it’s doing, return to the nearest sensible restart position, and allow you to continue where you left off.
This isn’t much different from insisting on “one-button builds,” except it’s an older phenomenon.
AES-1024 military grade encryption broken
This post is an analysis of a file encryption solution that claimed to implement “AES-1024 military grade encryption“. Spoiler alert: I did not break AES, and this work does not concern the security of AES. You may find advanced research regarding this topic.
This project started during a forensic analysis.
lockdown browser reverse engineered
This analysis was the culmination of a ~6 month journey. It is unfortunate, that the software considered the “gold standard” for remote proctored exams is in the current state it is. This post was motivated purely for informational purposes and I do not condone any of the following contents. This
A plain english introduction to CAP Theorem
CAP Theorem explained
You’ll often hear about the CAP theorem which specifies some kind of an upper limit when designing distributed systems. As with most of my other introduction tutorials, lets try understanding CAP by comparing it with a real world situation.

Fault tolerant distributed system failure; real world example and mitigation
Starting October 28th and fully resolving on October 31st, Roblox experienced a 73-hour outage.¹ Fifty million players regularly use Roblox every day and, to create the experience our players expect, our scale involves hundreds of internal online services. As with any large-scale service, we have service interruptions from time to
systemd, 10 years later: a historical and technical retrospective
10 years ago, systemd was announced and swiftly rose to become one of the most persistently controversial and polarizing pieces of software in recent history, and especially in the GNU/Linux world. The quality and nature of debate has not improved in the least from the major flame wars around
Visualizing Bayes Theorem
I recently came up with what I think is an intuitive way to explain Bayes’ Theorem. I searched in google for a while and could not find any article that explains it in this particular way.
Of course there’s the wikipedia page, that long article by Yudkowsky, and a
JWST sequential ranging
I decoded a recording I made with the Allen Telescope Array. I used an IQ sample rate of 3.84 Msps when doing this recording because I wanted to see if there were any ranging signals. Usually, ranging signals have a bandwidth of 1.5 MHz or less in baseband,
How a Single Line of Code Made a 24-core Server Slower Than a Laptop
Imagine that you wrote a program for a problem that is very easy to solve. Each thread does its own piece of work, and the threads don’t have to work together except to combine their results at the end. The more cores it runs on, the faster it is.
