The Hilbert transform is a linear operation used in telecommunications engineering to obtain spectrally efficient signals. It translates signals into a phase shift of -90º at positive frequencies and +90º at negative frequencies. In the frequency domain, the Hilbert transform results in a phase shift of 90°. The Hilbert transform can be applied to baseband […]

Firecracker, known for its speed and security, is a popular microVM hypervisor that is used by AWS Lambda for short-lived workloads. However, after testing, we discovered that Firecracker lacks support for crucial hypervisor features needed for long-running workloads, such as dynamic RAM management. While Firecracker is lightweight and optimized for short-lived workloads, it falls short […]
The address bar in Firefox serves as our gateway to the internet, and by default, the browser tries to intelligently guess what we want based on our input. If it resembles a URL, Firefox makes the request; if not, it sends the string to the default search engine. Usually, this works fine, but there are […]
The Video Game History Foundation and the Software Preservation Network have recently conducted a study on the availability of classic video games and the results are quite alarming. The study reveals that a staggering 87% of these games are critically endangered in the United States. In comparison, only 13% of video game history is being […]
Deep learning has made significant progress in various applications, but the widespread use of deep neural network models raises concerns about unfair biases and privacy protection. Machine unlearning is an emerging field that aims to remove the influence of specific training examples from a trained model. Retraining models can be computationally expensive, so an ideal […]
Perl is described as a language that can replace awk and sed. It is an interpreted language that is optimized for scanning and extracting information from text files, as well as performing system management tasks. The author believes that Perl combines the best features of C, sed, awk, and sh, making it familiar to those […]
I used to believe that buying new laptops was necessary for a good computer and quality work. However, after going through three laptops in 17 years, I decided to switch to a 2006 second-hand machine for just 50 euros. With a new battery and hardware upgrade, I spent less than 150 euros in total. If […]
