Science made simple

Hanra — Sat, 27 Feb 2021 10:36:28 +0000

Here is a small pen containing links to the Science made simple documentaries.
Originally the documentary was on a DVD that they stopped selling.
I thus, because I the documentary was so interesting, decided to upload it's chapters to my YouTube channel so that everybody can now learn from them.

I do not intend to steal their work. This is the Twitter page of the company @yorkfilms and here is their website YorkFilms of england.

These documentaries are a great source of knowledge. Unfortunately, they decided to stop selling the DVD, so that is why I decided to upload the chapters. more info is in the webpage of my pen.

color cells for programers

Hanra — Sun, 03 May 2020 01:12:31 +0000

I have created this code so that anbody who is looking for a big range of colours, can find it here. You might ask me, why did you do this colour table? Well, it isn't juste a colour table, it's a colour coded table. Depending on which css property you chose and if you want a semi-colum at the end or not, you will just need to choose in the two scroll-down list. The minute you made your choice, it will be applied on every single line that condains a colour tag. Usefull, isn't it?

If you like this project, please consider sharing it and not to forget to credit the author.

If you wish, an all in one version (no need of the js or the css file, all will be included in the same page), you can download it on this github page: https://github.com/HenraL/Color-Table

Follow-me

This page contains different follow me forms such as:

a side follow-me with icons

a position absolute head follow-me

a head follow-me with the same icons again

a footer follow-me

a position absolute footer follow-me (stage at the same place, no-mater if the text mooves)

an inner follow-me (usefull for aticle, to do an ad break in the middle)

If You use one of my free option, please, kindly, give-me your feedback on it, in:

either the Discord server (https://discord.gg/dtJTBn)

or on Dodepen (https://codepen.io/henry-letellier/pen/OJygPKY)

NSI_GLOUTONS (Greedy Algorithm)

Hanra — Mon, 27 Apr 2020 11:11:43 +0000

This is My first completely working html/JavaScript/CSS webpage hosted by codepen.
You can follow me on YouTube: http://bit.ly/34iZAK9
The program is written in French but is easily understandable

L’algorithme glouton consiste à donner les pièces de plus grande valeur possible (tant que cela ne dépasse pas la somme totale) puis continuer avec les pièces de seconde plus grande valeur etc.
L’ensemble dans lequel sont stockés les objets (des pièces de monnaie) est une tirelire , et ce n’est pas par catégorie que sont classées les pièces, mais avec pour but de totaliser une somme donnée.
D’ordinaire , pour payer 13 centimes , on donne une pièce de 10 centimes , une pièce de 2 centimes et une pièce de 1 centimes .
Mais que faire lorsqu’on n’ a qu’une pièce de 5 centimes et pas de pièce de 10 centimes ?
Plus généralement, on peut se demander de combien de manières différentes , on peut former 13 centimes ?
You can find the French version here: (https://codepen.io/henry-letellier/pen/GRpWWoY)

Greedy algorithms determine minimum number of coins to give while making change. These are the steps a human would take to emulate a greedy algorithm to represent 36 cents using only coins with values {1, 5, 10, 20}. The coin of the highest value less than the remaining change owed, is the local optimum. (In general, the change-making problem requires dynamic programming to find an optimal solution; however, most currency systems, including the Euro and US Dollar, are special cases where the greedy strategy does find an optimal solution.)
