rr aspires to be your primary C/C++ debugging tool for Linux, replacing — well, enhancing — gdb. You record a failure once, then debug the recording, deterministically, as many times as you want. The same execution is replayed every time.

rr also provides efficient reverse execution under gdb. Set breakpoints and data watchpoints and quickly reverse-execute to where they were hit.

WinPython is a free open-source portable distribution of the Python programming language for Windows 8/10 and scientific and educational usage.

It is a full-featured Python-based scientific environment:

    - Designed for scientists, data-scientists, and education (thanks to NumPy, SciPy, Sympy, Matplotlib, Pandas, pyqtgraph, etc.):
        - interactive data processing and visualization using Python with Spyder and Jupyter/IPython, Pyzo, IDLEX or IDLE
        - fully integrated Cython and Numba! See included example
        - connectors (cffi, odbc, rpy2, scilab2py, requests, ...) for advanced users
    - Portable:
        - Runs out of the box(*) on any Windows 8+ with 2GB Ram (Jupyter Notebook will require a recent browser)
        - The WinPython folder can be moved to any location (**) (local, network, USB drive) with most of the application settings
    - Flexible:
        - You can install as many WinPython distributions as you want on the same machine: each one is isolated and self-consistent
        - These installations can be of different versions of Python (3.7/3.8/3.9...)
    - Customizable:
        - The integrated WinPython Package Manager (WPPM) helps installing, uninstalling or upgrading Python packages
        - It's also possible to install or upgrade packages using pip from the WinPython command prompt
        - A configuration file allows you to set environment variables at runtime

WinPython is something different from other Python Distributions (see historic motivation and concept):

    - non-invasive: WinPython lives entirely in its own directory, without any OS installation
    - customizable: add your missing packages, zip the WinPython directory and give it to your students
    - do your own version: a winpython-creator kit is made available for you

The source code for the classic PSX launch title wipEout was leaked in 2022. A few month ago I finally sat down to take a look at it. The result is a (nearly) complete rewrite that compiles to Windows, Linux, macOS and WASM.

This post is a detailed discussion into user profiles, their directories, and how they are—to put it bluntly—in total disarray on Windows and Linux (I haven't used a Mac in ages, but I assume the situation is very similar there, too). Applications treat the user profile as a dumping ground, and any user with a reasonably wide list of installed software will find their user profile very difficult to traverse after some time in use. There are platform conventions and attempts to standardise things on more open-source platforms, but a lot of developers resolutely refuse to change the behaviour of their software for a variety of reasons (some less valid than others).

The first part is a deep dive into user profiles on Linux and Windows, and the conventions that have been established on these platforms over the years. The second section details how they are broken on each platform, and why they are broken.

This page lets you simulate various color vision deficiencies (CVD) directly in your browser. There are many simulation methods, with varying degrees of accuracy. Several are proposed here and they all have been carefully implemented in DaltonLens-Python by reviewing the state-of-the-art and testing them against reference implementations.

Earth has been a snowball and a hothouse at different times in its past. So if the climate changed before humans, how can we be sure we’re responsible for the dramatic warming that’s happening today?

In part it’s because we can clearly show the causal link between carbon dioxide emissions from human activity and the 1.28 degree Celsius (and rising) global temperature increase since preindustrial times.

But paleoclimatologists have also made great strides in understanding the processes that drove climate change in Earth’s past. Here’s a primer on 10 ways climate varies naturally, and how each compares with what’s happening now.

Fluency on the command line is a skill often neglected or considered arcane, but it improves your flexibility and productivity as an engineer in both obvious and subtle ways. This is a selection of notes and tips on using the command-line that we've found useful when working on Linux. Some tips are elementary, and some are fairly specific, sophisticated, or obscure. This page is not long, but if you can use and recall all the items here, you know a lot.

This app from NASA's EOSDIS provides the capability to interactively browse over 600 global, full-resolution satellite imagery layers on desktop and mobile devices. Many of the imagery layers are updated within three hours of observation, showing the entire Earth as it is "right now". This supports time-critical applications such as wildfire management, air quality measurements, and flood monitoring. Some satellite imagery layers span almost 30 years, providing a long term view of our dynamic planet. The underlying data is available for download, and Arctic and Antarctic views of several imagery layers are available for a “full globe” perspective.

On February 6th, 2018 SpaceX launched a Tesla Roadster on a Mars crossing orbit. We perform N-body simulations to determine the fate of the object over the next several million years, under the relevant perturbations acting on the orbit. The orbital evolution is initially dominated by close encounters with the Earth. The first close encounter with the Earth will occur in 2091. The repeated encounters lead to a random walk that eventually causes close encounters with other terrestrial planets and the Sun. Long-term integrations become highly sensitive to the initial conditions after several such close encounters. By running a large ensemble of simulations with slightly perturbed initial conditions, we estimate the probability of a collision with Earth and Venus over the next one million years to be 6% and 2.5%, respectively. We estimate the dynamical lifetime of the Tesla to be a few tens of millions of years.
