How to clean up Mail in OS X Yosemite

Question

On checking SSD disk on my MacBook Pro I noticed that ~50 GB free space has disappeared without any notification in the past few months. I did not install any new applications or big data, and already removed temporary files and caches, and cleared ~/Download folder and Trash. Safari, Mail, Adobe PhotoShop and Final Cut are extensively used. I heard that Mail cannot work well with Google mail servers and it may store tons of cache files. Deleted files and attachments are not removed from local storage etc. I have a couple of gmail accounts and some mails with large attachments. I am using IMAP google accounts and Mac Mail 8.2 on Yosemite 10.10.3. Is the source of the mess is the Mail? How to clean it up?

Configure NetBeans to test and deploy Raspberry Pi project

The Raspberry Pi (RPi) is a great strong device to play with. It is definiately not the perfect gadget to run resource hungry IDE, and develop c, c++, web… or Java applications on. Use your own laptop or desktop computer to build your code, test it and debug it while the code is running on the device. NetBeans for Mac (and Windows) is a reliable IDE with remote testing and deployment options.

Assign static ip address to Raspberry Pi

We usually want to develop and deploy applications and work with the Raspberry Pi (RPi) from a laptop or desktop computer. Use an external keyboard and an extra monitor only when there is no network access to the device. Your computer and RPi is likely connected to the same office or home network by using LAN connections or a WiFi router. The best way is to assign an ip address to the RPi to make sure it’ll always have an ip address that we know to be able to use SSH, remote desktop and application deployment tools. We have two popular options.
