Is there an actual difference between compiling and building?

Both terms are used daily in software development environments: "F***, compiling takes forever," or "Did you build after that last change?"... In reality, they're used pretty much the same way — and I’m guilty of that too. But is it actually correct to refer to compiling and building a project as if they meant the same thing?

Computer vision #2 | Image acquisition, characterization and interpretation

From the moment an image is captured until some information is inferred, various subprocesses are at work. These process the image as a set of pixels to classify and interpret different groups of pixels based on certain criteria. In short, they try to “identify” which objects are contained in a given scene.

Computer vision #1 | A brief introduction to computer vision

This is the first "chapter" of what will be a small series about computer vision—a very extensive area of technological knowledge that has caught my attention. I do not plan to follow a content script, so I will decide what to publish as time goes on. I am dedicating a lot of effort and care to studying it, so I hope that, as a reader, you enjoy it, share it, and, above all, learn something new each time.

Decrypt HTTPS (TLS) traffic using the SSL Key Log File | Wireshark @Windows 10

To go through the following practice, services offered by a network traffic capturer will be required. I opted for Wireshark, which can be downloaded from its official site https://www.wireshark.org/#download. It is easy to install and free to use.

An implementation for UDP & SYN Stealth (TCP) port scan | Scapy - Ubuntu 18.04

Every result obtained from the port scanning scripts will be compared to Nmap's to ensure they work correctly.

Installing Scapy software through the command $ sudo apt install python-scapy is necessary. Once installed, it can be launched by entering $ sudo scapy, although we will not use Scapy that way in this post.

'ps' system call implementation in xv6 operating system | Operating Systems - Sevilla's University

Under the pretext of a school volunteer project, I chose to dig into xv6 OS to understand how processes work in a given operating system. First, I had to download every tool needed to launch xv6 from Windows 10's command line. I also had to download xv6 itself.
