TL;DR Modern disks are so fast that system performance bottleneck shifts to RAM access and CPU. With up to 64 cores, PCIe 4.0 and 8 memory channels, even a single-socket AMD ThreadRipper Pro workstation makes a hell of a powerful machine - if you do it right! Update 1: Since 2021, networks have gotten faster and now it is possible to have high-speed reliable remote I/O even in cloud VMs! Here’s my recent article about testing an ..

Are you interested in processing images in Python? Do you need to load and modify images for your Flask or Django website or CMS? Then you most likely will be working with Pillow, the friendly fork of PIL, the Python imaging library. This week on the show, we have Mike Driscoll, who is writing a new book about image processing in Python.

I am presenting at two different events in February next month. Given the current COVID situation, that is entirely unexpected. In 2020 I only gave four talks , three of which were virtual. I am not holding my breath for 2021. Conferences are going virtual all year-long. Next year too, most likely. There are some clear advantages in going virtual, but the final result is a net negative. Any conference junkie will tell you that she/he att..

The original title included a short list of such positions, including gender nihilism. However, it was pointed out to me that a lot of gender nihilists do not actually hold transphobic views (only few people, who are not even considered nihilists by some, do), so I decided to remove that. This is yet another of those posts that mainly exists for the purpose of quickly debunking opinions I consider incorrect without having to write a full....

In a perfect world, you want to do vulnerability remediation on all issues and end with zero vulnerabilities. But you may not be able to fix all the vulnerabilities at once. You want to start with the most vulnerable issues that impact your application and start vulnerability remediation from there.

I still have no idea what actually was going on… Most of what I know is in this issue . Basically, my server was sending events successfully, yet, they did not show up on other servers, and then today, it suddenly worked again for whatever reason… In other news, fantasycookie17.onederfultech.com now redirects to fantasycookie17.cf, and I might get a "proper", paid domain during the next Netcup (my favourite registrar so far) sale, probab....

We’ve seen other articles pointing the finger at unnecessarily bloated websites. Terence Eden’s On the unreasonable effectiveness of simple HTML deserves mention, I think, for two reasons. First, the delivery is incredibly effective. Second, it is effective because of the storytelling. By enveloping the message into an original short, touching story, he achieves two goals. First, he captures the reader’s attention; second, he makes th..

Introduction Update: I wrote a follow up: Keeping platforms open . Check it out if you found this article interesting. I have never used WhatsApp, and never will. Despite this, I still feel the need to write an article about WhatsApp since it’s the perfect case study to help understand a class of businesses models I call “user domestication”. The domestication of users is high on my list of problems plaguing the human race, and is....

Imagine if you were able to pause your aging and just live at the same age forever − people might pick a time in their 20s or 30s so they could spend time partying; they might pick an older time when they’d have more money and wisdom; but nobody is going to say that they want to be 8 again and spend their time finger painting and learning to use scissors.

If you are a AWS SES user (AWS’ email system) you probably know that working with its JSON based templates is not a user-friendly task: Text and HTML content are defined as properties of a JSON object It’s a JSON file, meaning that you have to escape some characters, like " in the HTML It’s quite hard to find the content to change in the HTML being stored in a single line But still, is a quite convenient system, as hosting your own em....

When we come to using the container runtime in Kubernetes, these controls are used by the Kubernetes control plane to define which capabilities our container should be started with. The configuration for capabilities is surfaced to the user through various settings in the securityContext section of the YAML for a container.

Software should do one thing, and do it well. Each piece of software should have a clearly-stated goal that is used to determine whether a particular feature should be implemented or not. When a proposed feature does not fit with the software’s stated goal then don’t implemented it. Just don’t. Like adding source control to your product. We already have several perfectly good source control systems. Building your own custom source cont..

The purpose of this post is to provide instructions on how to setup a simple RESTful API server, in Golang, using only the net/http package and not any other third-party web framework. You will learn how to create REST endpoints within your project that can handle POST , GET , PUT and DELETE HTTP requests. This is the first post in a multi-post series.
