When you give access to developers to create firewall rules, they generally open all sorts of ports to the internet. All they need to do / expected to do is get the product working. The rest doesn’t matter. This was the same with the company I worked with. There were tonnes of firewall rules in the GCP projects which opened many ports to the public internet. One could think of deleting firewall rules straight away and check if something is ..

As of late, I have found myself writing a number of what amount to "Non Rails" tools. These are tools that tend to: Run continuously in the background Are deployed as SystemD services on Unix boxes Have the normal issues of coding complexities between development (OSX) and production (Ubuntu) Even though I normally just generate a Rails application for even my command line tools, this project felt like minimalism was called for and, we....

We forget passwords. Usually it's OK, because most websites implement a password reset feature. But how to do this in end-to-end encrypted applications that don't have access to the password in the first place ?

I’m always curious about expanding functionality and improving workflow by connecting devices to software that I already enjoy using. I love using Blender and making custom controllers for creating computer graphics is something very interesting to me. As long as a program has a scripting environment or a plugin support, you can usually connect anything you like to it. In one of my previous experiments I’ve added a serial communication ..

I like most of Leo Babauta’s work, but this one disappointed me. He titled it The Honest Guide to Mindfulness , but a more apt title would have been The Honest Guide to Meditation — because he talked about nothing else. Meditation, though, is a practice some have used to become more mindful, not the goal itself, and by no means the epitome of mindfulness. My favorite explanation of mindfulness came from an episode of Back to Work ,....

Rbenv provides a powerful tool for installing ruby on whether on your local box or on your server environment. While I have traditionally used RVM for local ruby development, I have found RVM problematic for use in a server context. As long as you are using bash -lc along with things like CRON jobs or System D , rbenv seems to be a great server side tool. My inspiration for this came from the Digital Ocean docs. As always, Digita....

Probiotiká sú dôležité aj pri helikobakterovi a refluxe – pálení záhy

Mnohí si myslia, že probiotiká sú prospešné len po užívaní antibiotík a ako pomoc proti premnoženiu plesňových infekcii. No okrem tohoto a ich významného vplyvu na imunitu a teda na celkové zdravie, sú veľmi nápomocné aj pri prevencii a liečbe helikobaktera a refluxu – ľudovo nazývaným pálenie záhy. Probiotiká v modernej strave chýbajú – to […]

This has bit me I think every single time I make a SystemD launch script using ruby and rbenv (RVM is worse; imho). Perhaps writing it down for once makes the lesson stick. Let's start with our SystemD unit file that doesn't work: [Unit] Description=Twitter To Kafka [Service] SyslogIdentifier=twitter_to_kafka User=ubuntu PIDFile=/home/ubuntu/twitter_to_kafka/twitter_to_kafka.pid WorkingDirectory=/home/ubuntu/twitter_to_kafka ExecStart=....

Introduction Welcome back to a new part in my blog series about my graduation project. As mentioned in the previous parts, the Fourier Transform will be dominant in the implementation of the Coherent De-Dispersion. This part will dive into the relevant theory behind the Fourier Transform. This includes another algorithm that is need to accomplish the implementation of the Fourier Transform: the CORDIC. The Fourier Transform DFT The Four....

Denis Shiryaev used neural networks to upscale a famous 1896 video to 4k quality

This is such a cool idea: Denis Shiryaev used Gigapixel AI’s neural network to upscale a classif video from 1896 into 4k; as Timothy Bee points out , a similar approach could then add color. One of my long-term projects involves making the small part of the internet I use every day available offline. As I lean toward a more nomadic lifestyle, I may not always have ready access to the familiar shows I stream on Netflix, for example, o....

I’m a FreeBSD guy. My first computer was a FreeBSD machine that my dad had running in a closet. I learned how to use Emacs as well as the command line on that black-screen white-text no-mouse interface. That’s how real programmers spend their childhood! 😎 😜 I’ve only heard good things about FreeBSD. While not known as particularly desktop-friendly (various Linux distros win here) I’ve heard tales of its rock-solid stability. I wanted to t....
