Replace your C3P0 or DBCP by Oracle pool (UCP)

Introduction : ODS or UCP? I've been using DBCP and C3P0 for a long time. But, a few months ago, I started to have problems with them. For example, sometimes, no way to get any connection to my database (while it's still possible with my Oracle SQL Developer). So, I decided to look at the code of C3P0. What a surprise! Even if it's a very common pool for a lot of projects (such as Hibernate), it seems to be dead.

DCcduino usb drivers (CH340 / CH341 chipset)

I've just received my first arduino platform. It's a DCcduino board (a clone of Arduino Uno). As I had some difficulties to have it recognised by my MacBook, I decided to share its drivers. This card has a CH340 USB-to-serial chip. You can find drivers for this chip on the web site of the chinese manufacturer, here : http://www.wch.cn/downloads.php?name=pro&proid=5 Or download it directly from my Google Drive. The archive contains drivers for Mac, Linux and Windows platforms. https://drive.google.com/file/d/0B5okZr5AW4gaX2pZaWt6dVNaSFU/edit?usp=sharing I hope this will help somebody. UPDATE for Mac users with Yosemite : Please, follow this extra instructions : Install the CH340 driver Run the command in Terminal: sudo nvram boot-args="kext-dev-mode=1" Reboot
