Prosper : comment ça marche ?

Depuis quelques mois, je m'intéresse à un concept très prometteur. Il s'agit des plates-formes qui permettent de mettre en relation une offre et une demande de crédit sans passer par l'intermédiaire d'une banque.

L'idée est que, si on supprime le « middle man » dans la transaction, le coût final pour l'emprunteur sera inférieur au coût d'un prêt standard ou, pire, d'une carte de crédits (j'écrirai un article à ce sujet dans le futur).

En tant que prêteur, l’avantage que je vois à ce système est double :

- Aider des personnes qui ont besoin d’un crédit pour se sortir d’une mauvaise passe ou qui, pour une raison ou une autre, ne peuvent pas demander un prêt standard à une banque ;
- Avoir la satisfaction de ne pas laisser une banque engranger un maximum d’intérêts pour ne payer qu’un taux ridicule en échange. Par exemple, un compte qui est supposé être rémunéré rapporte 2 ou 3 pourcents alors que la banque fait un prêt à 10, 12 ou 15 pourcents de l’autre côté, encaissant la différence.

Le site dont je parle est www.prosper.com et il faut montrer patte blanche avant de pouvoir l’utiliser en tant qu’emprunteur (borrower) ou prêteur (lender).

Pour être autorisé à devenir un prêteur, il m’a fallu donner mon « social security number », une photocopie de mon permis de conduire (qui sert aussi de carte d’identité) et authentifier mon compte chèque.

De la même manière, les emprunteurs doivent faire la même démarche, afin que Prosper (la société) sache qui ils sont et puisse déterminer leur profil de crédit, afin de déterminer le risque que l’emprunteur représente.

Le concept devient intéressant lorsqu’on apprend que l’idée principale pour minimiser le risque consiste à faire de petits prêts qui sont alors mis en commun.

Par exemple, si j’ai $1,000 à prêter, faire un seul prêt à une seule personne représente un risque important. Si cette personne ne me rembourse pas, je perds tout le capital restant dû au moment où le remboursement s’arrête. Par contre, si je prête $100 à 10 personnes différentes, je distribue le risque et si une personne arrête de me rembourser (on appelle cela « to default » en Anglais), il me reste encore 9 autres prêts. En d’autres termes, on peut dire que l’idée consiste à ne pas mettre tous ses œufs dans le même panier.

Le fonctionnement du système suit un principe d’enchères inversées.

Un emprunteur potentiel (une fois enregistré) va mettre en place une description de son besoin (combien d’argent) et un texte de quelques lignes pour expliquer sa situation particulière ainsi qu’un taux d’intérêt initial maximum qu’il accepte de payer.

Les prêteurs intéressés peuvent alors choisir combien ils veulent prêter et à quel taux minimum (forcément inférieur au taux maximum que l’emprunteur a défini).

Chaque demande de prêt a une date limite. Si le prêt n’est pas financé à 100% au moment où la date limite est atteinte, la demande est rejetée. Si le prêt est financé à 100% avant la date limite, d’autres prêteurs peuvent faire une contre offre, en baissant le taux d’intérêt minimum qu’ils acceptent d’être payés.

La valeur ajoutée de la plateforme mise en place par Prosper est de se charger de tous les détails techniques des enchères, de valider l’identité des acteurs et de pouvoir mettre en relation des prêteurs et des emprunteurs qui n’auraient quasiment aucun moyen de se rencontrer autrement.

Pour ceux qui sont intéressés, allez faire un tour sur www.prosper.com où vous pouvez naviguer sans avoir besoin de vous enregistrer. Seuls ceux qui veulent emprunter ou prêter de l’argent ont l’obligation de s’enregistrer.

Enfin la Green card !

Après plus de deux ans d'attente, j'ai finalement reçu la fameuse "green card" qui me donne le droit de vivre et travailler aux Etats-Unis indéfiniment. Enfin, quand j'écris "indéfiniment", il faut comprendre pour dix ans. En effet, cette autorisation légale doit être renouvelée tous les dix ans.

Prochaine étape, la nationalité ! Si je ne me trompe pas, dans mon cas, j'aurai le droit, légalement, de faire une demande de naturalisation dans un peu moins de trois ans maintenant.

Bref, le besoin de renouveler cette green card ne me dérange pas une seule seconde puisque que je serai citoyen bien avant qu'elle n'expire.

Crackintosh

Oh boy!

Now I get it. Now I know why people who have been using a Mac for some time always told me they just loved the experience. I got my brand new MackBook Pro this morning and this machine simply rocks!

First of all, the design of the case is gorgeous. Just look at some pictures on Apple's web site if you have never seen one before.

Second, the OS is very elegant. It feels like an extension of my brain.

Third, it is running Unix behind the scenes and it feels totally natural to pop up a shell and issue commands or simply log on to a remote server using ssh.

On top of all this, the machine is very quiet. The only moment I hear something is when the fan spins up when the CPU is running a heavy task for more than a few seconds.

Using this machine is definitely addictive.

I did it!

I finally purchased a MacBook Pro (the latest core 2 duo) from Amazon.com.

Interestingly, when ordering it from Amazon.com, I didn't have to pay sales tax, whereas ordering it from the Apple store online would have triggered an 8.25% California Sales Tax.

It should arrive on Thursday.

Getting rid of Windows (Finally)

Today, Apple officially released an upgraded version of its MacBook Pro. New CPU (Core 2 Duo) more memory, bigger hard drive, for the same price.

Sales of Macintosh laptops are growing at twice the rate of the global laptop market. Hmm... Let me guess. People are ditching their Windows laptops and are switching over to the Mac?

Since Windows Vista is almost ready to be shipped to retailers (I have the feeling this is going to be funny) I think it is now time to stop the BS and move over to the Mac side.

Time for me to finally switch over and buy my first Mac ever.

Getting rid of Windows (part 2)

I have finally found a little bit of time to work on removing Windows from my machines. The obvious choice (for those of us who need to use a computer to get our work done) is Linux or MacOS.

Unfortunately, when using a PC laptop (like Dell), one cannot legally install MacOS without an actual Macintosh. I know it can technically be done, but one has to hack the MacOS installer to bypass the initial test of the hardware that is in there to prevent it from being installed on a non Apple computer.

Being a computer professional, I believe one should pay a license (and respect its terms) when the product needs to be licensed.

We can all argue about the choice made by Apple, but in the end, they own the product (Mac OS) and we must follow their rules about licensing it.

So, until I actually buy a Mac (which I will probably do as soon as they release the new MacBook Pro) Linux is my only option to get rid of Windows.

Lately, Windows has triggered some really nasty feelings in my brain. This so-called "Operating System" keeps getting in the way. The network connections get dropped for no apparent reason (ok, it is easily fixed by rebooting) the system freezes from time to time for a few seconds (even the mouse doesn't move any more, what is crappy Windows doing under the hood?) etc.

I got a new PC and Windows is definitely -not- going to be installed on it. I even expressely asked my vendor not to install Windows on it nor to charge me a license fee (that looks more like a Microsoft tax.) I installed CentOS 4.3 on it and this machine is flying.

For my laptop, I purchased a new hard drive at Fry's and I installed Suse 10.1 on it. I migrated my emails, calendar, address book etc. over to the new system. It took a bit of time, but it was well worth it. No more questions like "what is the OS doing?" or "Why is it frozen now?"

I made the choice of Suse 10.1 because it contains a lot of tools for laptops and it was easy to install. The only trick I had to use with my laptop (a Dell Inspiron 600m) was to install a small package called "NDIS Wrapper" that implements an NDIS layer to be able to use a driver written for Windooz. Some hardware manufaturers still don't understand that providing a driver for Linux is to their advantage. Anyway, the installation of the NDIS wrapper was easy and now, I can use my wireless card in the laptop, using the driver written for Windows.

I don't think Linux is ready to be installed on every desktop/laptop in the world to replace Windows.

However, compared to the first version of Linux I was using back when I was a student (in 1994), it has made significant progress. The main limitation that I see is that Linux is giving you too much power and thus, too much responsibility with your system. The average user is probably not willing to spend the time to learn Unix.

There is hope, however. The hope of a world where Windows and Microsoft are not the de facto monopoly on the computer. India is now training its students, starting in High School on Linux only, not Windows any more. This means that these students will then go to College, using Linux instead of Windows. In less than ten years from now, India will have millions of people entering the work force who know how to use Linux and won't be willing to buy the crap MS is selling any more.

Windows is gone from my machines. Good riddance!

Getting rid of Windows (sort of)

In my quest to get rid of Windows on my machines (I know, it won't be completely gone, I still have a few software to work with that only run on Windows) I found a fantastic option: Linux with a Virtual Machine to run Windows in it.

I know I want a Mac (which, by the way, is running Unix behind the scenes) but while I am waiting for Apple to release its next generation of Power Books Pro, I am going to test this:

Mac On Stuff: How to run Windows XP under Ubuntu Dapper

Ubuntu is a distribution of Linux pre-packaged to be easily installable. I am definitely going to check it out. If Windows runs with a satisfactory speed, I will do a full backup of my hard drive (just in case) and will reformat it entirely to run Ubuntu only.

No more Windows!

That's it! I am switching over!

My wife has been telling me for a while now how using a Macintosh and its amazing OS X environment was so much more pleasant than #$@% Windows.

I am so over Windows right now. I won't write up a list of all the problems I have been confronted with, but it is simply amazing to me that so many people still use this unreliable piece of crap to work every day.

Lately, Outlook has decided to go on strike for no apparent reason. Unfortunately, I still need to use this software as I have a ton of emails that I need to get access to (yes I did archive them).

Now, Microsoft is touting another major piece of junk called Vista. Just by looking at the requirements, I can already see this thing is a joke. I ran their "Vista ready assessment software" and I found out that my machine won't be able to run Vista. So, I will have to buy YET another computer.

If I have to change my PC, I am going to change for good and buy a Mac. Now that Apple uses Intel CPUs I could even run Windows (I know I won't be able to entirely get rid of it, unfortunately) in a virtual machine, so that when it craps out (and it will, we all know Windows is not reliable) it will be in its own sand box.

Let's do the math here:

Option 1: I buy a new PC with Vista to run it. I obviously will have to spend about $1,000 to get something decent to run Vista. I have to re-learn an interface that Microsoft completely reshuffled just for the sake of it and will have to go through the pre-SP2 hell (we all know that an MS product is not stable before SP2 minimum.)

Option 2: I buy a Mac with OS X. Depending on what I want to do, I could get a Mac mini (dual core, 1 Gb of RAM, wireless keyboard and mouse) for about $1,000 too. I get to work on OS X that I already know and have access to Unix (since OS X is built on top of BSD.) As a complimentary feature, I get to work on a machine that doesn't crap out here and there without any warning.

In both cases, I won't have to buy a screen, since I would reuse the one I already have on my desk.

For most people, it makes sense to buy a Mac. If all you do is email, surf the web, edit a spread sheet or write a document in a word processor, Windows is not necessary. Even for those that have one or two applications that run only on Windows (like Visio), buying a Mac makes a lot of sense since you can still run Windows in a virtual machine by using a software like "Parallels" and still have access to your Windows only applications.

By forcing people to buy a new machine to run Vista, Microsoft is offering Apple an amazing opportunity to grab market shares since there is the cost of changing the hardware for both options. If we are forced to change the whole machine, then let's change for a better system.

My decision is made; my next machine won't be a Windows PC.

World Cup

Most of the world is currently preoccupied by the FIFA world cup. Once every four years, it looks like nothing else matters on this planet.

In the US, soccer is not as popular and most of the population simply doesn't care. Is it a big deal? I don't think so. People should be free to like what they want to like and simply ignore what they don't. It's the same concept with music. The different kinds of music exist because all the different tastes in the world are represented. We all simply ignore the music we don't like and choose to buy and listen to the music we do like. If people in the US would rather watch baseball or basketball, so what?

Many people ask me what I miss about France and Europe. I can't make a list of what I am missing just yet, but I can definitely say that not having to be bombarded all day long with the latest news about the World Cup like they do in Europe has given me an immense pleasure. I have the freedom to have a look on the web only when I want to.

That's one of the reasons why I love the US so much: freedom.

Graduation day!

Congratulations to my brother Laurent!

Last week-end I went to Evanston, Illinois for the graduation ceremony at the Kellogg School of Management. My brother earned two degrees. An MBA from Kellogg and a Masters of Science from the McCormick University.

He got his MBA with distinction (top 10% of the class) with a GPA of 3.86. Not bad for a non native speaker...

The best part though was to see the pride into my parents' eyes.

That was a moment I will never forget.

Bravo Laurent!
