Perché niente è impossibile da capire… Se lo spieghi bene !

The web platform is the delivery mechanism of choice for a ton of software these days, either through the web browser itself or through Electron, but that doesn’t mean there isn’t a place for a good old fashioned straight-up desktop application in the picture.
Fortunately, it’s easier than ever to write a usable, pretty, and performant desktop app, using my language of choice (Rust) and the wildly successful cross-platform GUI framework GTK.
GUI prototyped using Glade.
We often have to write code using permissive programming languages like C and C++. They tend to generate hard-to-debug problems that can crash your applications. Thankfully, many compilers offer “sanitizers”. I discussed them in my post No more leaks with sanitize flags in gcc and clang. I strongly encourage the use of sanitizers as I think it is the modern way to write C and C++. When many people describe how impossibly difficult it is to build good software in C and C++, they often think about old-school bare metal C and C++ where the code do all sorts of mysterious things without any protection. Then they feel compelled to run their code in a debugger and to manually run through it. You should not write code this way! Get some tools! Sanitizers can catch undefined behaviour, memory leaks, buffer overflows, data races, and so forth.

You’ve probably played with model trains, for instance with something like the Brio set shown below.1 And if you’ve built a layout with a model train set, you may well have wondered: is it possible for my train to use all the parts of my track?
These APIs, from niche but useful to just plain fun, should make any software developer smile. @Enterprisenxt
Rebuttal to the opinion of Christoph Buchal, Hans-Dieter Karl and Hans-Werner Sinn titled “Coal Engines, Wind Engines and Diesel Engines. What does the CO2 balance show?”
Britney Crystal Gallivan (born 1985) of Pomona, California, is best known for determining the maximum number of times that paper or other materials can be folded in half.
This is the 4th post in a series about migrating to functional programming. This week, I'll first implement the Dijkstra algorithm, then migrate the code to a more functional-friendly design. Dijkstra's algorithm allows to find the shortest path in any graph, weighted or not, directed or not. The only requirement is that weights must be positive.
If you have a digital audio device that can connect your guitar to a PC, here is some software you can use to record, edit and process the signal.
Learn about 5 interesting Linux tools that will help break your dependence on the GUI and keep you productive on the command line.
The type of organizing tools you use to plan your projects can make your work routine more efficient and improve your productivity. A project management application is an essential tool in some business environments. This week's Linux Picks and Pans takes a deep dive into some of the best project management software solutions available for the Linux desktop.
Firefox Send, send.firefox.com, is a free encrypted file transfer service that allows users to safely and simply share files from any browser.
Welcome This site is a blog dedicated to reviewing and cataloging useful command-line tools. There have been an amazing amount of useful utilities produced in the last few years, so many that it’s difficult to keep abreast of new applications that could potentially improve your workflow. I spend a silly amount of my free time trawling the internet for interesting tools, so I’d like to present the results with you!
Have you ever been in a situation where you are presenting to your manager or your manager's manager and you completely flub the opportunity by saying all the wrong things? Me too. It is from such encounters that I started to put together design patterns for handling these difficult situations. I like to think in systems and patterns, so applying this way of thinking to communication just makes sense. I have also found that these rules of thumb are useful to others, so I would like to share them here.
When you can spot the patterns, you can use some of the ideas presented here as guidelines to navigate these tricky, high-stress scenarios. This way you can feel confident and capable as a leader because you will know what to do: how to solve the problem and what steps to follow next.
Here are some of the most common challenging situations you may run into at work and how you can handle them.
- Someone asks you something you don't know
- There is a problem that is your fault or responsibility
- There is a decision that you don't agree with
- Your manager gives you negative feedback
I am a bit dissatisfied with the use of the Tragedy of the commons to represent issues with free and open source software development. It is not an abstract resource that can be depleted when overused. It is not magically maintained if left alone.
It is based on the work of people, and we should not erase those people.
Unfortunately (and it is by design), most of the licences and the vocabulary around it are focused on the software’s user. After all, they work by reducing the creator’s right to empower the user.
As examples of this vocabulary, we have the distinction between “free as in beer” and “free as in speech” to show that the “free” word in “free software” has more to do with freedom and people’s rights to use, study, modify and share a program, than its actual price. Although, in practice, the overwhelming majority of FOSS will not cost you anything.
Error handling is an integral part of programming, but in many popular languages, it comes as an afterthought.
The godfather of numerous programming dialects, C, never had a dedicated error or exception mechanism in the first place. It is up to the programmer to accurately report whether the function did what it was intended to do, or threw a tantrum—usually by relying on integers. In case of a segmentation fault—well, all bets are off.
