Yesterday I attended to the SF NewTech Meetup in San Francisco. This is a Meetup there new Start-Ups can present themselves and hire new people.

Actually the Event is in a pretty cool location with high brick walls, a nice bar and cool paintings.

The special Thing on this Meetup is that every Speaker have just 5 min to talk. Actually there is big red timer running down from 5 min to zero. If the timer is down the time for the Speaker is over. In the next 5 min the audience have time to ask questions. And than everything is starting again with another Speaker.

Every SF NewTech Event have his own Theme. The Theme this time was “API”. So I heard some cool stuff about some of the APIs which are out there in the deep Internet. I learned a lot new stuff. Did you know that SalesForce is making 500 mil. transactions per day over their API? Much more than over regular Browser Requests from human users. And far much more than Microsofts Cloud Service. Actually SalesForce is a bigger Cloud Service than Microsoft!

Yesterday I attended to the Java Meetup at Square. Square is one of the hottest Start-Ups in the Bay Area. They are providing Credit Card Payment over mobile devices like iPhone and Android.

Maybe you saw already one of this small Card Reader devices from Square.

You can put it into your iPhone, iPad or Android Phone. Like this.

With the Square App on you phone you can just enter the amount you want receive from your buyer. Than the buyer just has to slide his Credit Card through the device. In the next step the buyer has to sign with the finger.

In the next step the buyer can enter an email address, so that he can receive an receipt.

You as seller can see the transaction in the Square Webapplication at http://squareup.com. I tried it today with a friend of my and 2 USD. In my square account it looks like this.

So the payment was over 2 USD. I received on my account just 1.94 USD. 0.06 USD (2.75%) goes to the Square company. Fair enough.

It shows me even on the map where the transaction happend. That is pretty easy and cool.

And this is the main entry of the office.

They have a pretty cool Office in San Francisco on the 5th Street.

Everybody is working on Mac Books and huge Apple LED Cinema Displays. I guess there are 60 people in the office.

I heard that Square is looking for 15 more Java Developers.
