Visual complex analysis: first chapter exercises
"Visual complex analysis" it's a very good book, with really good exercises.
Abstract and symbolic execution notes (with possible application on reverse engineering)
This post will be probably a too ambitious one, since I'm going to write about a very theoretical aspect of computation, in particular the so called abstract interpretation: for now let me just say that this field tries to give the best possible answer to unsolvable characterization of computer programs.
Another point of view that I want to address is the use of this kind of analysis with reverse engineering, since a lot of aspects between these two kind of analysis are shared.
This post will have pretty mathematical formalism but should be readable enough also without a PhD.
Reversing C++, Qt based applications using Ghidra
This post is going to be too ambitious probably: I want to introduce you to
reversing C++ code, applying this knowledge in particular to Qt
applications and since we are at it, explaining some ghidra scripting to
automate the process.
side channels: power analysis
This is a post in a serie regarding side channels, from the theoretical and pratical point of view; the posts are
- introduction on the model of computing devices (to be finished)
- using the Chipwhisperer (here)
- power analysis (this post)
- glitching (to be finished)

Reusing old shit: laptop keyboard
Here we are with another experiment in reusing otherwise trash-destined electronics material; in this episode we are going to refurbish a keyboard, from the recovering of the internal "matrix" to the design of the PCB destined as the controller board, to finally reworking of an existing firmware to create a new USB keyboard.
blog migration to Nikola
After running for a couple of years using jekill as a static site generator
I decided to switch to nikola for a couple of reasons: first of all because
is implemented in python, a language that I know more than ruby and this
allows me to improve the platform and customize it more to suite my needs.
Reusing old shit: creating a BSP using Yocto for the Samsung Galaxy S (S5PV210)
In this post I'll describe my esperiments in reusing my old Samsung Galaxy S; don't expected anything sophisticated, it's more a brain dump.
Reusing old shit: lcd screen
It's happened in the past that someone gifted me of very old (and not working anymore) laptops that otherwise would have been thrown in the garbage; my idea for them was of reusing some parts that are more valuable: battery, disks, keyboards, etc...
