Comment publier son premier ebook: Les étapes indispensables - Les erreurs à éviter

J'ai publié au mois de mars un ebook simple et que j'espère limpide sur les étapes à suivre pour bien publier son premier ebook sur Kindle. J'insiste sur le bien, car il y a malheureusement encore trop d'erreurs de novice qui sont faites par les personnes qui s'y essaient.

Avec ces erreurs de novice, on risque d'être décçu, or il y a une opportunité très importante de publier, de vendre et de développer cette activité.

Toutes les personnes que je connais et qui publient sur Kindle ne le font pas pour en vivre ou gagner de l'argent. Certaines oui, d'autres uniquement pour être publiées. L'avantage de la plate-forme du Kindle est justement que cela devient possible de se lancer pour une dépense raisonnable. Et après on peut investir si on y voit une opportunité. On peut aussi bien sûr investir directement si on est persuadé(e) que c'est cela qu'on veut faire.

Bref, vous pouvez télécharger cet ebook presque gratuit (en tout cas pas très cher) sur Amazon et en profiter pour vous aussi éditer vos livres en ebooks.

PS : pour moi cela ressemble à ce que j'ai fait en développement iPhone. J'ai fait une première application simple qui m'a rapporté quelques dizaines d'euros. Quand j'ai vu le potentiel et ce qu'on pouvait faire, j'ai investi plusieurs milliers d'euros pour aller suivre une formation au Big Nerd Ranch Europ en Allemagne. Qui m'a rapporté des dizaines de fois son prix parce que j'ai développé une nouvelle compétence. J'ai trempé le pied puis j'ai plongé. Sans regret.

2014-05-31 Heart rate training : the link

Where can you find "Efficient Heart Rate Training" ?

I'm a slacker.

Sorry, but it's true. I am. I announce things and then I forget to talk about them when they are released.

So, to repair things : I did write a few months ago a book on heart rate training that's avaialble on iBooks and Kindle.

If you're on a mac, an iPhone or an iPhone, you can use this link to review and buy the book in iBooks.

If you have a kindle or prefer Amazon, you can use this link.

Both of them are affiliate links, but given the price of thes book, I don't expect to retire tomorrow ;-)

Use PhotoGPS with Aperture

Are you a frequent image shooter?

If you have an iPhone, it's easy to know where you have taken a picture, and once they're imported in Aperture, you can use the Maps to find pictures based on a location.

But what if you don't exclusively use your iPhone ?

For example, I have a DSLR old Canon, with a great lens (50mm from Canon, yes the plastic one), and a better, but heavier great lens (30mm f/1.2). And I also have a simple and useful Panasonic GH1.

The pictures taken with these cameras are by default not geotagged, no position in their metadata. And doing it by hand is … a pain.

The solution is to use PhotoGPS, a small and simple app I made that allows you to record your position ALL THE TIME without killing your battery and export that info.

With PhotoGPS, you just launch the app once, and it will always record where you've been, based on your cell network towers and wifi networks. If you want a better position, you launch it again and it will use GPS to know where you are, with up to 9 m precision.

You can then review and export your positions based on the date.

Once you want to geotag pictures in Aperture, export the data from your iPhone by selecting the dates you're interested in. You'll get them by email in a .gpx file attached yo your email.

In Aperture, first select the project you want to work one.

Then select the places in the upper RIGHT corner (it'a a globe icon)

Just under the map, on the lef side, you'll find a button called "GPS"

Import the file you got by mail, and you'll get the lines describing your course. Then select an image taken at a precise location, drag it on the precise location on the line, and Aperture will ask if it needs to locate all pictures based on the time etc.

Et Voilà !

New publication: Efficient Heart Rate Training

I just published a new book on Amazon Kindle, Efficient Heart Rate Training, a short book on why, how and for what benefits you should measure your heart rate while training for a run, both with a watch or an iPhone.

Of course, given that I am also the developer of 321Run, I am more prone to advise you to use an iPhone app.

Here is the description


Did you know how much you can benefit from a heart rate measure to better train for running? Even if you are just beginning?

Heart rate training is the best way to know your effort, measure it, know your body and improve your health and well being. Wether you are looking for weight loss or to improve your fitness, it will help you understand where you are, where you need to go, and how you can improve.

This ebook goes into the scientific knowledge that supports heart rate training and explains in common language these facts. It helps you test yourself and define your goals in simple, understandable words. It provides you with the essential knowledge to be able to start planning a regular fitness exercise, improve immediately your current training, and feel better with a few exercises.


The iBooks version is still in review by Apple but should be published in a few days.

Enjoy!
