une matinée cerf-volant

February 15, 2010 3 comments

Les faits selon Dimous …

On a fait une journée de cerf-volant! Pendant que je tenais le cerf-volant, mon papa m’a jeté en l’air pour voir si je peux m’envoler et le cerf-volant m’a emporté! Mon papa, il m’a vite rattrapé: “Ouf! je t’ai rattrapé!”
(Ce texte est de Dimitri)

Sinon, nous avons aussi quelques photos … qui montrent qu’avec du vent et un cerf-volant de traction petits et grands peuvent bien s’amuser.

Ca c’est Dimitri … et ce qu’il a raconté plus haut est vrai … il y avait tellement de vent qu’il tenait à peine au sol et que quand j’ai essayé de le jeter en l’air (en l’attrapant sous les bras)  il s’est effectivement envolé et j’ai du vite sauter en l’air pour le rattraper! Dommage qu’on n’ait pas de photo de cet évènement!

Lucas aussi a fait du cerf-volant … mais là j’ai pas trop essayé de le faire voler 🙂

Et ça, c’est Tatiana … elle aussi tenait à peine au sol!

Et quelques vidéos … pour ceux qui veulent plus de détails et qui voudraient aussi voir le cerf-volant

Quelques explications …

Aujourd’hui c’est le “Lundi Propre” en Grèce … ne me demandez pas ce que c’est exactement … l’important est que c’est un jour férié, qu’il a fait très beau avec du vent et que selon la tradition grecque, ce jour est dédié aux cerf-volants.  Nous avons donc ressorti le super cerf-volant de traction que Tatiana m’avait offert il y a bien longtemps … vous savez un de ces cerf-volants qu’on utilise aussi pour le kyte surf mais en plus petit … et on s’est bien amusés.

Recette de Beurre Maison

Comment faire du beurre soi-même sans matériel particulier.

Ingrédients et Matériel

Une petite photo vaut toujours mieux qu’un long discours …

Tout ce dont on a besoin pour faire du beurre

Tout ce dont on a besoin pour faire du beurre


  • 1 pot de crème fraiche liquide complète (35% de matières grasses)
  • 1 pincée de sel


  • 1 pot en plastique avec un couvercle (qui ferme hermétiquement)
  • 2 petits bouts de bois (1cm de long)
    On peut par exemple couper des bouts d’une baguette chinoise
  • Un torchon blanc (type torchon pour essuyer la vaisselle)
  • Un pot pour mettre le beurre


La préparation du beurre doit se faire à froid: il ne faut donc pas trop traîner.

  • Verser la crème fraiche dans le pot de plastique
  • Rajouter le sel
  • Mettre les 2 bouts de bois
  • Bien fermer le couvercle
  • Secouer énergiquement pendant 10 à 15 minutes
    On peut ouvrir le couvercle de temps en temps pour voir le beurre se former. Dans le pot, on voit se former petit à petit une masse jaune grumeleuse (le beurre) et un liquide blanchâtre (le bas-beurre ou petit lait).

    Après 15 minutes ... le beurre s'est séparé du bas-beurre

    Après 15 minutes ... le beurre s'est séparé du bas-beurre

  • Sortir le beurre du pot en plastique et le mettre dans le torchon

    Le beurre est dans son torchon prêt à être essoré

  • Bien essorer le beurre pour faire partir toute l’eau (sous forme de gouttelettes à la surface du beurre). En profiter pour le malaxer afin qu’il perde son aspect grumeleux.
  • Transvaser le beurre dans son pot à l’aide d’un couteau
  • Decorer le beurre par exemple avec un moule à pate à modeler
  • Mettre rapidement le beurre au frigo

    Une fois dans son pot, on peut même le décorer

Bon appétit !

Sur une tartine de pain bien frais, on appréciera le bon gout de ce beurre maison!

Learning Qt

June 3, 2009 Leave a comment

I have been really impressed by the KDE desktop for quite a long time now and being myself a software engineer, I have decided to learn Qt programming.

My main problem here is that I am not fluent in C++, the truth is that I have been a J2EE programmer for the last 5 years and more. So my first concern is to refresh / complete my knowledge of C++. In order to do so, I have borrowed a copy of the excellent but quite difficult  book: “The C++ Programming Language” written by B. Stroustrup and started reading it.

In the XX paragraph I stumbled on a the calculator example: I found the algorithm interesting and decided to widen the scope of my Qt experiment the following way. I will first convert this algorithm in Java and Javascript, two languages that I know quite well. In each of these languages I will then write a Graphical User Interface on top of the algorithm using a well known toolkit: For the Javascript language, my choice will go to the excellent Ext JS toolkit, where for Java language I will use the classical Swing toolkit. As you can imagine my third implementation language will be C++ and the Qt toolkit for the GUI.

In the end, I hope I will have learned something in C++ and Qt, but more generally I also expect to learn something from the comparison of the three languages and toolkits used in my experiment. I will post thoughts, results, code … anything I find usefull on this experiment in the near future.

What you can learn from a pair of gold fishes

April 29, 2009 Leave a comment

This post is about gold fishes and how surprisingly complicated it is to set up an aquarium for only 2 of them…

Some weeks ago, my oldest son received a pair of gold fishes in a small plastic bowl as a present for his birthday. He was very pleased with the present and so was my youngest son who spent hours during the days following their arrival, talking to the fishes and knocking on the bowl with his little fingers to “wake them up”.

The problem with gold fishes is that you cannot decently leave them in a plastic bowl, can you? These lovely little creatures produce an incredible amount of waste, probably proportional to their appetite and thus, the water in the bowl needs to be changed very frequently … too frequently I would say. That was the main reason why all the family decided to buy an aquarium for our 2 beloved gold fishes.

We went to a pet store very close to our house and bought a nice aquarium of 40 liters that we naively thought would be quite enough for our 2 little fishes. Then, when the time came to set up the aquarium, we discovered that the task was much more complicated than we first thought and began searching the Internet for information on gold fishes and aquariums.

And there was the surprise … aquariophilia is a world apart with its own inhabitants, rules, web sites, shops, books etc. And if you dive into this world, you surely learn a lot of things … and also spend a lot of money 🙂

This is the reason why I decided to write a post about some of the things I have learned so far concerning the art of aquariophilia in general and more specifically the branch that deals with gold fishes.

  • First of all, a 40 liters aquarium is a small aquarium … a “nano cube” as I read somewhere! I was really disappointed when I learned that I had spent 85 euros on an aquarium clearly too small even for my son’s 2 beloved gold fishes. Anyway, I don’t plan to change the aquarium for the time being as the 2 fishes are still very small and the aquarium much bigger than the initial bowl.
  • It is easier to set up a big aquarium than a small one. By big people usually mean more than 100 liters: it quickly became obvious to me that I had chosen the hard way.
  • Setting up an aquarium is a long and difficult task (especially if the aquarium is small). When setting up an aquarium, people should count weeks if not months before they can be sure of the result. Don’t rush, is what everybody says because the final result you expect is a real working ecosystem. An interesting information that should also be kept in mind is that putting the fishes in the aquarium is one of the last steps in the setup process: for 1 up to 2 weeks your aquarium will only contain water, rocks, gravels and plants.

Now let’s look at some rules more specific to the gold fishes themselves:

  • Gold fishes should never be kept in a bowl! This very common practice is commonly described as the most cruel thing that a human being can do to a gold fish. Beware, some aquarists may become aggressive when it comes to fishes and their well-being 🙂
  • When setting up an aquarium you should count 30 up to 50 liters per gold fish depending on their age! The main reason for this is that a gold fish is fast growing fish which can reach 20 cm in size. Moreover, gold fishes produce a lot of dirt and may easily poison themselves in a small aquarium. Finally, gold fishes like to swim and “feel” better if they have enough space for it. Our 2 gold fishes would have needed a 100 liters aquarium at least … 😦
  • Gold fishes like “cold” waters (up to 22 degrees Celsius). All other fishes that are commonly found in pet stores are tropical fishes that like much warmer waters: unfortunately it is theoretically impossible to mix your gold fishes with anything else than … a gold fish. I initially wanted to buy some more different fishes for my (too small) aquarium: that was one more reason why I had to abandon the idea.
  • Gold fishes “hate” to be alone: you should always buy them by 2 or 3. This means that you should have a 100 liters aquarium at least and a lot of free square meters in your apartment.

At the time of this writing, I have started the setup process of my too small aquarium. The 2 gold fishes are still in their plastic bowl waiting for the aquarium to be ready. If you are as patient as they are, you will soon learn some more about gold fishes, aquariums and the wide world of aquariophilia. Until then …

A starting point …

April 29, 2009 Leave a comment

I opened this blog some weeks ago not knowing what I was going to do with it … I just wanted to see what a blog is and how it works. Now that I have seen, I can say I am quite impressed with the tool and the functionalities provided: so I decided to give it a real try.

This blog will be about me, all the different things that interest me and have some kind of impact on my life: that’s as selfish as possible but also close enough to the primary meaning of my blog’s title. As far as I can see from this starting point the subjects addressed here should range from computer sciences to gold fishes with some stops on family, children, religion or politics.

I don’t really expect people to find anything interesting in my writing but I am also experimenting on the psychological benefits of sharing one’s own experience on a public and somehow anonymous media. However, if for some reason I get feedback from my posts … I will be pleased of course 🙂

Finally, I am not a native English speaker but I will mostly be writing in English to get the widest possible audience: so be kind, you who read me and forgive my mistakes.
