Part 1: How your user experience changes for the worse as the open web gives way to walled gardens I hang out in two circles. Open web enthusiasts that are lamenting its demise, and regular users who are happy with their fast snappy apps and couldn’t care less. These

The excitement around Apple’s new M1 chip is everywhere. I bought a MacBook Air 16GB M1 to see how viable it is as main development machine – here’s an early report after a week of testing. Xcode Xcode runs FAST on the M1. Compiling the PSPDFKit PDF SDK (debug,

My thoughts before I post Amazon’s response: Running out of file handles and other IO limits is embarrassing and happens at every company, but I’m surprised that AWS was not monitoring this. I’m also surprised at the general architecture of Kinesis. What appears to be their own

The purpose of this post is to document our trial, error, and best findings with regards to manual and automatic memory collection in Go. Our excitement for Go has gone beyond building systems, and has led us to even write scripts in Go that would typically be written in Bash

Apple has now released the M1 Apple Silicon chips, and after all the fuzz you may be wonder what makes it different from an intel or AMD processor? You have probably heard M1 referred to as an ARM processor and that ARM is a so called RISC processor, unlike x86

Please note: this occurred in 2018, and has been properly patched and archived. The vulnerabilities were immediately reported to Blackboard and the NTNU Security Operations Center on the 9th of February 2018. They were confirmed patched 61 days later. How did the Blackboard exploit work? A student (attacker) submits an

One of many timeless works from Butler Lampson. The patterns are still widely in use to this day. The trade offs between lease times and availability are clearly defined; reading this could save a lot of hard earned lessons. This paper is such a great top-down explanation of consensus and

For my money there is perhaps nothing more valuable than in situ kernel debugging. The ability to ask questions of any part of the kernel, on a live production system, without stopping or pausing anything, is quite frankly, amazing. One such avenue to in situ kernel debugging is the DTrace

Today, I wanted to take the time to dissect the statement I hear countless times: “Computers are all made out of logic gates”. From this we deduce that logic gates are very simple machines, analogous to light switches. This raises the question: how exactly do kind-of-light-switches come together to form

This article originally appeared on the-scientist.com; however, I found it quite problematic and intriguing at the same time, so I decided to share. This article highlights the pitfalls of predatory research journals, pseudo-science, and boosted citation counts. The majority of what is presented on this website is my own

RSA is an intrinsically fragile cryptosystem containing countless foot-guns which the average software engineer cannot be expected to avoid. Weak parameters can be difficult, if not impossible, to check, and its poor performance compels developers to take risky shortcuts. Even worse, padding oracle attacks remain rampant 20 years after they
