In order to limit the number of bugs, particularly for huge programs, we started to thin about how to best organize computer programs.
|

In the end, from the imperatives language culture, it produced the Object Oriented programming (OOP).
|

Beware, the Object Oriented programming isn't a miracle. Proof? How many bug-free software do you use?

Furthermore, OOP doesn't fit all problems.

The ugly
|
||||
|

Industry wanted an Object Oriented Language without loosing all their old C code.
|

Solution, keep C and add an Object layer on it.

The main concern about C++ is it do too many things.
|
||||
I particularly appreciated multiple inheritage and templates.

I particularly appreciated multiple inheritance and templates.
|

In reality I liked a lot C++ while I was working alone.
|
||||
I used it to write `DEES` my main thesis software.
|
||||
My only concern was about a lack in the STL.
|
||||
In the doc, one could use `String<T>`.
|
||||
But in reality, T have to be only `char` or `char16`.
|
||||
Then I had to reduce my alphabet to $2^16$ letters.
|
||||
Then I had to reduce my alphabet to 2<sup>16</sup> letters.
|
||||
Except for some application, the alphabet must be far larger than that.
|
||||
|

To conclude, I'd say, C++ is very good if you work alone or with a fixed subset of its features.

### Eiffel
|
||||
|
||||
<%=leftblogimage("eiffel.jpg","Eiffel tower construction")%>
|
||||
|
||||
Yes, it is a really nice language.
|
||||
Full object in mind. Far cleaner than C++.
|
||||
But it isn't so popular.
|
||||
Behind C++ there is a large community to help new users and to write libraries.
|
||||
Furthermore, I preferred working with C++.
|
||||
At that time I programmed a lot with C and like its syntax.

### Java

There was incrusted inside the language architecture concepts to help limit mistakes, and force you to use good programming habits. But...
|

But It is extremely verbose.

||||
And limitations are quite boring if you know what you're doing.
|
||||
|
||||
For example, there is no multiple inheritance.
|
||||
Generally it is a coherent choice if it is compensated by something else.
|
||||
In Java, there are interfaces.
|
||||
Except, interfaces are a way to add only methods to classes.
|
||||
In no way, you can add any attribute.
|
||||
It was really a lack to make a graphic interface.

Generally it is a coherent choice when there are a way to compensate.

In Java, there are interfaces for this.

Except, interfaces can only add methods to a class.
|
||||
You cannot add any attribute to a class except by subclassing.
|
||||
I really lacked this feature.
|
||||
|
||||
I made a GUI using Java Swing and I created my own notification system between different element of the GUI.
|
||||
Then, at the begining I only needed to send notification 1 to 1.
|
||||
After some times, I needed to make 1 to many notifications.
|
||||
And I add to make a bunch of copy/paste inside all my subclasses!
|
||||
Copy/paste are exactly what should be avoided the most by Object oriented languages.

Concerning haskell, this is very different.

The concepts behind haskell are really deep.

The community behind haskell is very friendly and nice. There is no "LOL! URAN00B! RTFM!"

And no concession on the language as been made to make it more popular. Therefore this langage remain pure (I know there is two meaning).
|
||||
To master haskell you need to understand very hard concepts.
|
||||
Monads and Arrows are some of them.
|
||||
I didn't understand them before I read some scientific paper.
|
||||
Many week will be necessary to master it perfectly (if someone does).
|
||||
Also the community is very friendly and nice. There is no "LOL! URAN00B! RTFM!"

||||

What make metapost very good?

It contains a linear solver.

This is really usefull to draw things.
|
||||
This is really useful to draw things.
|
||||
For example if you write:
|
||||
|
||||
<code class="ruby">
|
||||
x=(2*y+z)/2
|
||||
AA=1/3[A,B]
|
||||
</code>
|
||||
|
||||
It will place the point x at 2/3 of y and 1/3 to z.
|
||||
This feature is very nice. Most programming language should think about adding it.
|
||||
It will place the point `AA` between the point `A` and `B`.
|
||||
More precisely at the barycenter `(2xA + B)/3`.
|
||||
|
||||
<code class="ruby">
|
||||
X=whatever[A,B]
|
||||
X=whatever[C,D]
|
||||
</code>
|
||||
|
||||
This second example, will place the point X at the intersection of the two segments `AB` and `CD`.
|
||||
|
||||
This feature is very helpful, and not only to draw things.
|
||||
Most programming language should think about adding it.

I had only given my impressions.

But I used them all.

Of course, my feelings are highly subjectives.

## Langages originaux

||||
En plus des langages de programmation proprement dit, il existe des langages dont le seul but et de créer des documents.

|
||||
### MetaPost
|
||||
### Metapost
|
||||
|
||||
Metapost est un langage qui permet de programmer des dessins.
|
||||
Le gros plus de metapost, c'est qu'il y a un solveur d'équations linéaires.
|
||||
Ainsi on peut faire des choses assez impressionnantes, comme laisser une petite distance entre les flèches et les bords.
|
||||
Ou encore les têtes des flèches se courbent.
|
||||
Très sympatique à utiliser.
|
||||
Le gros plus de metapost, c'est sa capacité de résoudre automatiquement les systèmes d'équations linéaires.
|
||||
Par exemple, si vous écrivez :
|
||||
|
||||
<code class="ruby">
|
||||
x=(2*y+z)/2
|
||||
AA=1/3[A,B]
|
||||
</code>
|
||||
|
||||
Il va position le point `AA` entre `A` et `B`.
|
||||
Plus précisément, au barycentre `(2A + B)/3`.
|
||||
|
||||
<code class="ruby">
|
||||
X=whatever[A,B]
|
||||
X=whatever[C,D]
|
||||
</code>
|
||||
|
||||
Ce deuxième exemple positionne `X` à l'intersection des deux segments `AB` et `CD`.
|
||||
Vous pouvez aussi voir pas mal d'[exemples ici](http://tex.loria.fr/prod-graph/zoonekynd/metapost/metapost.html).
|
||||
You could see [more example there](http://tex.loria.fr/prod-graph/zoonekynd/metapost/metapost.html).

Cette fonction est très utile.

||||
Et à mon avis pas seulement pour afficher des choses.
|
||||
De mon point de vue, les autres langages de programmation devraient penser à rajouter les résolutions automatiques simples.

fr: J'ai appris CamL à la fac, j'avais trouvé cette expérience très interressante. J'étais plutôt bon, et j'avais les bonnes intuitions mathématiques qui vont avec la programmation fonctionnelle. Mais je dois avouer que je ne l'ai plus jamais utilisé. Simplement, ce type de langage semble si loin de ce qui se fait pour fabriquer des produits que ça me donnais vraiment l'impression d'être un langage pour chercheurs.
|

en: I learned CamL during the college. I founded this really interresting. Functional programming is very different to imperative one. I had good mathematic intuitions to use this language. But I must confess I never used it for something serious.

fr: Metapost est un langage qui permet de programmer des dessins.
|
||||
fr: Le gros plus de metapost, c'est qu'il y a un solveur d'équations linéaires.
|
||||
fr: Ainsi on peut faire des choses assez impressionnantes, comme laisser une petite distance entre les flèches et les bords.
|
||||
fr: Ou encore les têtes des flèches se courbent.
|
||||
fr: Très sympatique à utiliser.
|
||||
fr: Le gros plus de metapost, c'est sa capacité de résoudre automatiquement les systèmes d'équations linéaires.

fr: Par exemple, si vous écrivez :
|
||||
en: Metapost is a language to program drawings.

en: It contains a linear solver.

en: This is really usefull to draw things.
|
||||
en: This is really useful to draw things.
|
||||
en: For example if you write:

<code class="ruby">
|
||||
x=(2*y+z)/2
|
||||
AA=1/3[A,B]
|
||||
</code>
|
||||
|
||||
en: It will place the point x at 2/3 of y and 1/3 to z.
|
||||
en: This feature is very nice. Most programming language should think about adding it.
|
||||
fr: Il va position le point `AA` entre `A` et `B`.
|

fr: Plus précisément, au barycentre `(2A + B)/3`.
|

en: It will place the point `AA` between the point `A` and `B`.

X=whatever[A,B]

En java, il existe les interfaces.

<h3 id="metapost">Metapost</h3>
|

|

<p>Metapost est un langage qui permet de programmer des dessins.
|
||||
Le gros plus de metapost, c’est qu’il y a un solveur d’équations linéaires.
|
||||
Ainsi on peut faire des choses assez impressionnantes, comme laisser une petite distance entre les flèches et les bords.
|
||||
Ou encore les têtes des flèches se courbent.
|
||||
Très sympatique à utiliser.</p>
|
||||
Le gros plus de metapost, c’est sa capacité de résoudre automatiquement les systèmes d’équations linéaires.
|
||||
Par exemple, si vous écrivez :</p>
|
||||
|
||||
<pre class="twilight">
|
||||
x<span class="Keyword">=</span>(<span class="Constant">2</span><span class="Keyword">*</span>y<span class="Keyword">+</span>z)<span class="Keyword">/</span><span class="Constant">2</span>
|
||||
<span class="Variable">AA</span><span class="Keyword">=</span><span class="Constant">1</span><span class="Keyword">/</span><span class="Constant">3</span>[<span class="Variable">A</span>,<span class="Variable">B</span>]
|
||||
</pre>
|
||||
|
||||
<p>Il va position le point <code>AA</code> entre <code>A</code> et <code>B</code>.
|
||||
Plus précisément, au barycentre <code>(2A + B)/3</code>.</p>
|
||||
|
||||
<pre class="twilight">
|
||||
<span class="Variable">X</span><span class="Keyword">=</span>whatever[<span class="Variable">A</span>,<span class="Variable">B</span>]
|
||||
<span class="Variable">X</span><span class="Keyword">=</span>whatever[<span class="Variable">C</span>,<span class="Variable">D</span>]
|
||||
</pre>
|
||||
|
||||
<p>Ce deuxième exemple positionne <code>X</code> à l’intersection des deux segments <code>AB</code> et <code>CD</code>.
|
||||
Vous pouvez aussi voir pas mal d’<a href="http://tex.loria.fr/prod-graph/zoonekynd/metapost/metapost.html">exemples ici</a>.
|
||||
You could see <a href="http://tex.loria.fr/prod-graph/zoonekynd/metapost/metapost.html">more example there</a>.</p>
|
||||
|
||||
<p>Cette fonction est très utile.
|
||||
Et à mon avis pas seulement pour afficher des choses.
|
||||
De mon point de vue, les autres langages de programmation devraient penser à rajouter les résolutions automatiques simples.</p>

|

C’est un langage qui essaye de résoudre les contraintes autant qu’il le peut pour vous.

C’est assez magique.

Il en ressort un impression de magie.
