Why do you need to place your servers geographically close to your users? One of the reasons is to achieve lower latencies. That makes a lot of sense when you are sending short bursts of data that should be delivered as quickly as possible. But what about large files, such as videos? Surely there is a latency penalty…
Explore the internals of the BEAM VM in comparison to the JVM, highlighting the significance of understanding these components.
Your laptop spends all day lying to you. If you want your code to run well on server hardware, best write it on server hardware.
Trying to figure out how Linux containers work by implementing them from scratch in C.
Introduction: Beginning in Insider Build 17063, you’ll be able to use the unix socket (AF_UNIX) address family on Windows to communicate between Win32
For the last few years, Microsoft has stated during event keynotes and in other places that Linux is a rapidly growing operating system (OS) being used within Microsoft Azure. They had proudly stat…
I have taught operating systems at my university, so I will link my notes from that course here regarding the virt I/O protocol. This protocol has changed over the years, but the one that QEMU implements is the legacy MMIO interface.
Vacuum is one of the sub-systems in PostgreSQL which gets improved with each release. I have checked past five releases and each has qu...
Clang is an “LLVM native” C/C++/Objective-C compiler, which aims to deliver amazingly fast compiles […]
Huawei has seemingly stepped its foot into the kernel self-protection game with the release of HKSP. Absent any threat model and riddled with weaknesses, it also introduces a trivially exploitable local root vulnerability due to a complete lack of defensive programming.
Recently I was digging deeper into Raft , an important algorithm in the field of distributed systems. Raft is a consensus algorithm , meaning that it is designed to facilitate a set of computers agreeing on a state of the world (more on exactly how the state of the world is represented later), even when communications…
Tim Kadlec writes about performance, product management, and the web.
...and the crucial role it plays in modern operating systems.
Soon the Windows May 2020 Update (20H1) will be released upon the world. This update will contain some nice UI improvements, but most relevant to me it allows Web Developers on Windows to upgrade to WSL 2. This is a significant milestone in the #davegoeswindows saga and it’s worth posting about what it means going…
I’ve noticed a small pattern across a few of my projects where I had vectorized and parallelized some code. The original algorithm had a “push” approach, the optimized version instead took a “pull” approach. In this article I’ll describe what I mean, though it’s mostly just so I can show off some pretty videos…

What's a race anyways? Most of the readers, for sure, do know what a race condition is. Let me however include short description just fo...
WebGPU is a new graphics and compute API designed on the grounds of W3C organization (mostly) by the browser vendors. It’s designed for the Web, used by Java...
I spent last week-end getting accustomed to CUDA and SIMT programming. It was a prolific time ending up with a Business Card Raytracer running close to 700x faster [1] , from 101s to 150ms. This pleasant experience was a good pretext to spend more time on the topic and learn about the evolution of Nvidia architecture…
Julia 1.5 is gaining a cool new bug reporting capability, leveraging mozilla's rr project to automatically create fully-reproducible bug reports
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 2012-2014, and systemd…
