Very often, backend devs don’t want to write code. For this, we use one trick : derive HTML widget for presentation, database access, REST endpoints from ONE SOURCE of truth and we call it MODEL. A tradition, and I insist it’s a conservative tradition, is to use a declarative model where we mad the...

   Right now, I am on a never ending quest that requires me to think of building a full fledge MVC controller : an anti jira tracker that would favours HARD CHECKED facts over wishful thinking. For this to begin, I am not really motivated in beginning with a full fledged MVC Model View Controller à ...

   I was on a french speaking IRC chan bragging a tad about how I was doing a guitar tuner and paying attention to not fall into the pit of confusing precise and exact figures as a random computer engineer. Science he was a patented CS engineer he wanted to prove me that my new guitar tuner was...

   Today’s exercice is just about turning a very nice example of the python soundevice module into something that works for me to help me tune my bass. Long story short, I suck at tuning my instrument and just lost my tuner... This will require the python module soundevice and matplotlib. So in order...

   In part I we explored the pre requisite in order to code print : having a grasp on the framebuffer. Here, we are gonna deep inside one of the most overlooked object oriented abastraction : a file and actually print what we can of hello world in lines of code. The file handler and the file...

   The hello world example is about standing on the shoulders of the giant and learn how to use function as tools. Most coders will use print during their whole life without actually coding it. However, it is a fun exercise. The framebuffer Given you are on linux you probably have a device...

   Wishing to prove my assertion wrong on python tk that piping python directly into tk tcl interpreter is simple I tried to contradict myself by making a full GUI in matplotlib. Because, if you are not aware : matplotlib supports multi target Wx, Qt, gtk, tk, html multi platform widgets Button,...

   Maybe, you want to experiment small stuffs in wish the tcl tk interpreter because of a post claiming that direct python tcl tk is simpler in some simple cases than tkinter. As a convinced tkinter FreeSimpleGUI user, I see this as an extreme claim that requires solid evidences. When all is said...

   Last time I exposed an old way learned in physical labs to do C or python tk like in the old days: by summoning a tcl tk interpreter and piping commands to it. But what fun is it It’s funnier if the tcl tk interperpreter talks back to python :D as an hommage to the years awaited TK versions...

   Well, the PySimpleGUI rug pulling of its licence reminded me how much dependencies are not a good thing. Even though FreeSimpleGUI is a good approach to simpler tk tcl binding in python : we can do better, especially if your linux distro split the python package and you don’t have access to...

   I liked pySimpleGUI, because as a coder that likes tkinter the Tk Tcl bindings and as a former tcl tk coder I enoyed the syntaxic sugar that was avoiding all the boiler plates required to build the application. The main advantage was about not having to remember in wich order to make the pack...

   Recently I decided to get back to the basics and question my use of classes frameworks. I tried to find a definition of the word framework but weirdly this word is a tautology, no one knows what it is, but it refers at itself for something people use to get the work done through the use of...

   After the stupid example with the taxonomy of the species car employees that makes you do a lot of inheritance one of the valid use case for OOP is D geometry : points amp; rectangles. This is the python example in wiki.python.org https: wiki.python.org moin PointsAndRectangles Don’t worry,...

   In my job, I sometimes have to deal with web applications that are pointing to half a dozen databases with an overall of more than tables. Not to say it can be complex, but sometimes it is : So I made a small script using of my favourite technologies to deal with that: graphviz, and...

   Heard of randomness What is random: something that given a serie of chronological events happening after one another whatever long the time serie is, we cannot predict the future. Two kinds of events are random; purely random events stochastics or mathematically deterministic equations that...

   I told fellow coders: hey I know a solution to the safe eval problem: it is right under my eyes . I think I can code it in less than hours from scratch. It will support safe templating... Because That’s the primary purpose for it. TL; DR: I was told my solution was overengineering...

   Preamble, I know about this excellent article: http: nedbatchelder.com blog eval really is dangerous.html I have a bigger objection than ned to use eval; python has potentially unsafe base types. I had this discussion with a guy at pycon about being able to safely process templates and...

   While we have a convention in python for numbering: http: legacy.python.org dev peps pep We can mostly say that version numbering thanks to Windows has shed an interesting spotlight on version comparaison. They are to tenants of version handling: the naïves who consider...

   So let’s speak of what and un deterministic code really are. I am gonna prove that you can achieve nearly chaotic series of states with deterministic code o Definitions: Deterministic: code is deterministic if the same input always yield the same output Chaotic: a time serie of value is...

   In real life there are companies were keywords kw are prohibited, and others where positional arguments can stack up as high as seven. Let’s state the obvious concerning arguments: Human beings are flawed The positional arguments are fixed arguments. Some are mandatory others are...

   So the actual buzz is gender issues http: www.kathrineswitzer.com written about.shtml I dare say it is a non problem. But before let me tell you my story as a cross dresser ... on the internet. Once upon a time I signed up for a famous dating site. And as advised by a friend, I was told to...

   Learning that signals were software interrupts in a book on Unix, I thought, hey, let’s try to play with signals in python since it is in stdlib The proposed example is not what one should really do with signals, it is just for the purpose of studying. Well remember this point it will prove...

   I remembered opening books of Computer Science to learn algorithm when I began. And my first reaction was: it seems unnecessarily complicated like maths, but I must be an idiot since I learnt physics. So years later I reopened Introduction To Algorithms By Thomas H Cormen, Charles E...

   So today, I dared open a bug on python. Which at one point should make me feel mortified, since it has proven that I misunderstood what a character is. The point was in python . : fooâ bar File stdin , line fooâ bar SyntaxError: invalid character in identifier...

   Well, I remember overhearing a conversation one day in a laboratory once years ago. Electronic engineers were proud to have helped their team to higher CDD resolution with a trick they published: they would use a median filter to filter out the photon arriving from the CDD from the...
