Bravada Bravada is the new game from Ukraine developers Interbellum Team that features a cheery little story. This game differ from most of the others for it’s gameplay, in short it’s a mix of a vertical scroller with RPG and turn based strategic game.

Story and Setting:

The game follows the story of a young dwarf who has yet to acquire his own beard and dreams of having his own adventures. When he is awoken from his dreams his only adventure is looking after chickens but all is not what they seem when he enters the chicken coop. The chickens were being mind controlled and they attacked him on sight. Its up to him to save the chickens and slay the slimes that are controlling them. This is only the beginning of our young heroe’s story and the mystery of why he hasn’t grown a beard will be revealed in a humorous tale. The story will take you to many different locations based on different locales including forests, beaches, caves and dungeons. The story is told using hand drawn cutscenes and Zelda style voice acting (grunts and hums).

Dstat is a versatile replacement for vmstat, iostat, netstat and ifstat. Dstat overcomes some of their limitations and adds some extra features, more counters and flexibility. Dstat is handy for monitoring systems during performance tuning tests, benchmarks or troubleshooting.

Dstat allows you to view all of your system resources in real-time, you can eg. compare disk utilization in combination with interrupts from your IDE controller, or compare the network bandwidth numbers directly with the disk throughput (in the same interval).

Dstat gives you detailed selective information in columns and clearly indicates in what magnitude and unit the output is displayed. Less confusion, less mistakes. And most importantly, it makes it very easy to write plugins to collect your own counters and extend in ways you never expected.

Dstat’s output by default is designed for being interpreted by humans in real-time, however you can export details to CSV output to a file to be imported later into Gnumeric or Excel to generate graphs.

For what I know there isn’t an official google drive application for Linux and so after looking around I’ve found that there are some interesting project that you can use to access your data on Google Drive from your linux, and in particular today I’d like to show 2 of them:

Grive and Grive Tools: These 2 tools are good if you want to use Google Drive on your laptot or Desktop or in general in a graphical environment.

google-drive-ocamlfuse: This is more suited if you want to mount your Google Drive from a server or from a terminal, in fact this software will mount your Google Drive as File System and you’ll be able to move inside it and see all your files, like a local file system.
