A few days ago I started my day with my Twitter feed full of articles saying something like: “75% of Redis servers infected by malware”. The obvious misquote referred to a research by Incapsula where they found that 75% of the Redis instances left open on the internet, withou...

Ahhh.. meetings. The one old school company thing that survives in this agile, open-office, ‘remote first’, nomadic worker world. And it is easy to see why: the ‘meeting’ is the last guaranteed way to get everyone to pay attention for an hour, or at least, pretend to. It still is rare for people to fake attending two meetings at the same time in any case. The late great Andrew S. Grove, long time CEO of Intel and overall hero engineer, wrote the massively important book High Output Management.

The problem that's been bothering me for a week

When you hear “atomic design,” you probably think of Brad Frost. Interestingly, he was not the first person to develop that method of delivering design as components, or even the terminology. Brad published his atomic design article in 2013. While digging through the arch...

It is upsettingly easy to work hard without being productive. The Lean Startup includes a quote I really liked: “[People] feel that a good day is one in which they did their job well all day.” The point being that this doesn’t account for whether you are doing the right wo...

[This blog post is also experimentally available on Medium: https://medium.com/antirez/a-short-tale-of-a-read-overflow-b9210d339cff] When a long running process crashes, it is pretty uncool. More so if the process happens to take a lot of state in memory. This is why I love ...

As of today, February 6th 2018, from around 3:50 PM, there is a Tesla Roadster headed to Mars.

Today marked the first successful launch of the SpaceX Falcon Heavy, a rocket ship than can carry other rocket ships. Not only did the Heavy, which can carry more payload than any other ship besides the Saturn V, launch successfully, but its rocket boosters then deattached and landed themselves, successfully, so that they can be reused for the next launch.

The car is currently in geostationary orbit within the Van Allen radiation belt, testing radiation shielding for "Air Force intel missions". It has live coverage and will launch for Mars within the next 8 hours.

To reiterate:

THERE IS A CAR IN SPACE.

That is all.

I saw multiple users asking me what is happening with Streams, when they’ll be ready for production uses, and in general what’s the ETA and the plan of the feature. This post will attempt to clarify a bit what comes next. To start, in this moment Streams are my main priority...

Comments are very welcome on bert@hubertnet.nl or @bert_hu_bert. Update: several constructive remarks have been used to improve this text. Thanks! In this post I will attempt to fully explain the Spectre and Meltdown vulnerabilities in an accessible way. I decided to write it up after I realised it took me more than a day to figure it out, even though I’ve been doing security related stuff on CPUs for 20 years.

The story of how I set up this site

I decided one day that I really wanted a remote server.

Hello, World!

Four days ago a user posted a critical issue in the Redis Github repository. The problem was related to the new Redis 4.0 PSYNC2 replication protocol, and was very critical. PSYNC2 brings a number of good things to Redis replication, including the ability to resynchronize jus...

Welcome to Kolmo There are three avenues to learn about Kolmo (GitHub). There are two Youtube videos, one from the most excellent NLNOG 2017, the other from the equally excellent UKNOF 38. These videos explain a lot of the the history and the ‘why’ behind Kolmo. There is also the kolmo.org website, which is ‘self-hosted’ by the ws Kolmo-powered webserver. Finally, there is this post, in which I focus on what Kolmo actually does, without spending much time on the ‘why’ or the history.
