I'm a passionate problem solver that use code, design and empathy to help people through their digital challenges. Hi, my name is Marco and this is where I collect my thoughts, intuitions and ideas on the IT industry (and more). Occasionally, I do contribute to open-source projects and share some ideas with my fellows . If you are more into philosophy you should give a try to the manifesto . Online you can find me ..

Welcome to the newest Snyk blog series! In this monthly series, Snyk looks back on the vulnerabilities discovered by or reported to our research team. We choose one noteworthy vulnerability from the past month and tell the story behind the discovery, research, and disclosure of the vulnerability. We highlight the researchers, developers, and users who are helping identify and remediate vulnerabilities across the open source community.

When working on command-line utilities which can be useful for various platforms, from Windows on x86 to Linux on MIPS, the existence of a cross-compilation is highly attractive. A number of different binaries can be constructed conveniently from a single, typically powerful host system.

Migrating your workloads to Azure can help you leverage the benefits of cloud computing. This includes agility, scalability, lower costs, and easier management. However, the process of migration can sometimes be complicated. You have to select the proper service model for every workload and establish a migration strategy for all workloads. A well-planned migration strategy can help you make the move without impacting your business. The foll....

This post presents a DoubleMAD-based outlier detector that handles asymmetric and heavy-tailed distributions using the Harrell-Davis quantile estimator. For symmetric scale estimation, Pragmastat recommends Spread — the Shamos estimator — as a more efficient alternative to MAD. Confidence intervals are available via SpreadBounds . pragmastat.dev github.com/AndreyAkinshin/pragmastat Outlier detection is an important step in da....

At Jane Street, we have some experience using FPGAs for low-latency systems–FPGAs are programmable hardware where you get the speed of an application-specific integrated circuit (ASIC) but without being committed to a design that’s burned into the chip. It wasn’t so long ago that FPGAs were expensive and rare, but these days, you can rent a $5,000 card on the Amazon AWS cloud for less than $3 an hour.

Here’s how attempting to export images off a Word Document led to a quest for data deduplication and classification using the shell. The images I wanted to export were MS Word diagrams drawn in Word, rather than PNG files 1 . Because those doodle-shapes do not export to PNG well, I first copy-pasted them into Powerpoint to get the familiar “save as picture” context menu. But a couple of images were still deformed beyond recognition.

Then and now Link to heading I remember when the internet, or more specifically the web, was new. There was so much hope and optimism. Early adopters talked excitedly of the seemingly endless ways in which it would revolutionise so many aspects of society in positive ways. There was the idea that “information wants to be free”, where free, at least how I understood it, was free as in “libre” (freedom) rather than “gratis” (zero ....

Introduction This is another blog post related to the Build Systems à la Carte paper. See Using type-classes to model the expressivity of build systems for the first one. The paper proposes splitting build systems into two components: Rebuilders decide when to rebuild a particular key (file). Schedulers decide how to rebuild multiple keys - handling dependencies while maintaining correctness and efficiency. Schedulers come in 3 flavors (see..

I was around during the birth of the web in the early 1990s and have enjoyed every twist and turn since then. Even before creating my own personal website and blog (this site) in 1998, I maintained the Department of Science website at UW (originally http://sciborg.uwaterloo.ca ). And while I’ve enjoyed watching the evolution of the web, I still think the old web was more fun. In this blog post, I’ll tell you why. But first, let’s cover s..

What I want to do in this article is to go through the costs associated with shooting film in 2020, and specifically in Canada. There are many YouTube videos and articles about film photography in Germany or in the United States but not much is said about Canada.

Tonsky recently had a great post about 4K monitors, fonts and scaling. The magic in this article are his suggestions around how to set fonts on your OSX machine. Apparently Apple does not set the defaults correctly (and, I'm writing this on a brand new OSX box that is NOTABLY improved by following his directions). This is the kind of stuff that I'm going to need to refer back to hence this post. Discussion thread about this . How t..
