In 2018 I set out to replace our XenSever 7.2 based virtualisation after Citrix essentially screwed over free / open source users . This project was to directly replace XenServer 7.2 with something supported and manageable for our traditional virtualisation needs. High Level Selection Considerations I evaluated a number of options, with the primary candidates below. Key criteria (at a high level) I was evaluating: Ease of moving f....

Autoscaling was a great addition to DynamoDB and it lets you forget about assigned capacity. Here’s how we implemented our own algorithm to improve on this idea. 10-15 minute read DynamoDB is a NoSQL key-value database service provided by AWS. We use it at the core of many of our systems, since the consistent read latency is awesome for realtime applications. If you are not entirely familiar with it, it might be worth refreshing the ba....

A recently discovered vulnerability in NumPy, the widely used open source package for scientific computing in Python, allows for the execution of arbitrary, potentially malicious code.

January brings in a brand new year, which means I’ll be reading brand new books… Or maybe I’ll be reading old books. In either case, they’ll be new to me.

As of today, Snyk enables importing, scanning and monitoring of .NET projects directly within GitHub, GitLab, and Bitbucket without having to move away to Snyk.

When I tried to fix the situation, I realized how little I actually knew about the event-loop behavior and gained some realizations that at first surprised me and some fellow developers I shared this with. I believe it’s important that as many Node developers will have this knowledge too - which led me to writing this article.

I was contacted for this, as a result of research I'd previously conducted into the feasibility of delivering high resolution video via encrypted overlay networks (in this case, Tor). The customer was a small group of people who had an idea, but weren't sure on how best to implement it - the idea being a privacy sensitive service delivering legal adult content, in effect a PornHub without all the tracking and profiling that MindGeek doe..

mgmt @ FOSDEM : Later today I’m giving four talks about mgmt at FOSDEM . I’m also giving two more on the following day. (One is a 5 min lightning talk.) I don’t know how I got accepted for so many talks, I just replied to the CFP for every room where I thought I had something interesting to share, and well, here we are! I got rejected for the main track again, but I guess it’s up to me to make my work more generally appealing firs..

In a previous blog post we detailed how we used OCaml to reproduce some classical deep-learning results that would usually be implemented in Python. Here we will do the same with some Reinforcement Learning (RL) experiments.

TL;DR < You can find the source code here . I used the Wii Nunchuk controller to prototype one handed controller for creating computer graphics. I used the Blue Pill board which carries a STM32F1 microcontroller with a built-in USB peripheral . That allowed me to implement it as a true USB HID (Human Interface Device) for the Windows OS . The results were disappointing. My USB HID implementation was poor. I have fixed sev..

The Knapsack problem is one I’ve encountered a handful of times, both in my studies (courses, homework, whatever…), and in real life. Unfortunately, the times I encountered it in a real situation I never had to actually fully solve it – it was more along the lines of, “hey, this is just like the Knapsack … Continue reading "0/1 Knapsack Discrete Optimization w/ Dynamic Programming"

Earlier this month it was found that Bower, a popular web package manager, is vulnerable to archive extractions and currently, we can associate two security incidents with it, for which follow-up releases to address them are available:

Today we’re delighted to share that we’re launching our Open Source Security Runtime Monitoring solution, in beta, to all users, with no limitation on usage! While Snyk invests heavily in making fixing vulnerabilities ridiculously easy by baking it into the development workflow, handling a large backlog of issues can be time-consuming.

I have used the “5 whys” approach multiple times to get to the root of some question. This article advocates adding a time dimension to the decision. Not only should we consider why we are doing something, we should also consider why we are doing something at a specific point in time. It also twists this around and suggests we should consider “What is the danger of not doing this right now?” - what would we lose or miss?

From my first post in July 2017: I expect much of the content here to be around the subject of what we now call Cyber Security, since this is a field I began researching around 1990 and have worked professionally within for years in both an offensive and defensive capacity. Cyber Security (or just security as we used ..
