rr: lightweight recording & deterministic debugging

3 août 2024 à 17:31
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

19 janvier 2024 à 10:04
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

Home, Not So Sweet Home

28 août 2023 à 03:10
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.

Online Color Blindness Simulator | DaltonLens

29 août 2022 à 06:40
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.

How Earth’s Climate Changes Naturally (and Why Things Are Different Now) | Quanta Magazine

22 juillet 2020 à 06:36
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.

The Art of Command Line in one page · jlevy/the-art-of-command-line

23 mars 2020 à 23:32
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.
